Abstract:

Abstract Utility service provision is designed to satisfy basic human needs. The main objective of the research is to investigate mathematical methods for evaluating the feasibility of using a more efficient approach for utility services provision, compared to the current diversity of utility products delivered to households. Possibilities for alternative utility service provision that lead to more sustainable solutions include reducing the number of delivered utility products, on-site recycling and use of locally available natural resources. The core of the proposed approach is the simulation system that enables carrying out feasibility study of so-called transformation graph, which describes direct transformations and indirect transformations of the utility products into defined services. The simulation system was implemented in C# and .NET 3.5, while the XML database was implemented using eXist-db. The XML database stores information about all devices, utility products, services and technologies that can be used to define and solve services-provision problems. An example of such problem and its solution is presented in this paper. This research is a part of the All-in-One Project.

Abstract:

This paper presents Quality of Service analyses in wired and wireless IP networks based on the three popular techniques – RSVP, IntServ, and DiffServ. The analyses are based on a quick approximation schema of the traffic system with static and dynamic changes of the system bounds. We offer a simulation approach where a typical leaky bucket model is ap- proximated with a G/D/1/k traffic system with flexible bounds in waiting time, loss and priority. The approach is applied for two cascaded leaky buckets. The derived traffic system is programmed in C++. The simula- tion model is flexible to the dynamic traffic changes and priorities. Student criterion is applied in the simulation program to prove results. The results of the simulation demonstrate the viability of the proposed solution and its applicability for fast system reconfiguration in dynamic environmental circumstances. The simulated services cover a typical range of types of traffic sources like VoIP, LAN emulation and transaction exchange.

Abstract:

Mountain ecosystems have special ecohydrological services, and the study of water conservation and soil conservation services in the Qilian Mountain Ecosystem (QLME) in China has important theoretical value for scientific understanding of the ecological processes and mechanisms of mountain ecosystems. In this study, we quantitatively estimated the spatial-temporal changes of water conservation and soil conservation services in the QLME based on the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) model and estimated the future ecosystem services (ESS) of the QLME under RCP4.5 (Representative Concentration Pathways) and RCP8.5 scenarios using the coupled Geosos-FLUS model. Firstly, the QLME ecohydrological service increased from 1985 to 2018, and its spatial heterogeneity was high in the east and low in the west. Among them, water conservation first decreased and then showed a trend of fluctuating increase, and soil conservation services decreased sharply from 2010 to 2015. Secondly, there are differences in the ecohydrological services of the QLME under different land-use types. The water conservation capacity in descending order is glacier snow, grassland, forest land, wetland, and cultivated land. The soil conservation intensity from strong to weak is woodland, grassland, arable land, glacier snow, and bare land. Thirdly, under different scenarios, QLME water conservation and soil conservation functions will increase to varying degrees over the next 30 years. The water conservation in the RCP4.5 scenario is higher than that in the RCP8.5 scenario, and the higher discharge scenario will lead to the decline of the water conservation service function. The increased rate of soil conservation was greater under the RCP8.5 scenario. With the development of Nationally Determined Contributions (NDCs) and scenarios below 2 °C, the future of QLME ecohydrological services will be further understood.

Abstract:

The growing number of vehicles in cities has a great impact on our quality of life, such as air and noise pollution, traffic jams and traffic accidents. Cooperative Intelligent Transportation System (C-ITS) relies on communication technologies to provide innovative services and applications for transportation and traffic management. In the C-ITS context, users, roadside infrastructure and vehicles need to be connected and, for this purpose, a wide variety of wireless technologies can be used (e.g, vehicular WiFi, cellular and visible light communication). In this work we consider a VANET (Vehicular Ad-hoc NETwork) using vehicular WiFi (based on 802.11p). The communications in VANET networks have been studied for years and several routing algorithms have been developed for such a kind of network. However, a benchmark to compare the performance of such algorithms is still lacking. To fill this gap, the present work proposes a benchmark composed by instances of data routing for different scenarios in the VANET. Moreover, we propose a multi-objective algorithm based on ACO (Ant Colony Optimization) to compare with such benchmark. The results of simulations show the impact of several factors in the VANET connectivity, such as vehicle density, geographical location, propagation and fading models. The results are promising and indicate the importance of choosing appropriated simulation models.

Abstract:

For more than a decade, communication systems based on the IEEE 802.11p technology—often referred to as Dedicated Short-Range Communications (DSRC)—have been considered a de facto industry standard for Vehicle-to-Infrastructure (V2I) communication. The technology, however, is often criticized for its poor scalability, its suboptimal channel access method, and the need to install additional roadside infrastructure. In 3GPP Release 14, the functionality of existing cellular networks has been extended to support V2X use cases in an attempt to address the well-known drawbacks of the DSRC. In this paper, we present a complex simulation study in order to benchmark both technologies in a V2I communication context and an urban scenario. In particular, we compare the DSRC, LTE in the infrastructural mode (LTE-I), and LTE Device-to-Device (LTE-D2D) mode 3 in terms of the average end-to-end delay and Packet Delivery Ratio (PDR) under varying communication conditions achieved through the variation of the communication perimeter, message generation frequency, and road traffic intensity. The obtained results are put into the context of the networking and connectivity requirements of the most popular V2I C-ITS services. The simulation results indicate that only the DSRC technology is able to support the investigated V2I communication scenarios without any major limitations, achieving an average end-to-end delay of less than 100 milliseconds and a PDR above 96% in all of the investigated simulation scenarios. The LTE-I is applicable for the most of the low-frequency V2I services in a limited communication perimeter (<600 m) and for lower traffic intensities (<1000 vehicles per hour), achieving a delay pf less than 500 milliseconds and a PDR of up to 92%. The LTE-D2D in mode 3 achieves too great of an end-to-end delay (above 1000 milliseconds) and a PDR below 72%; thus, it is not suitable for the V2I services under consideration in a perimeter larger than 200 m. Moreover, the LTE-D2D mode 3 is very sensitive to the distance between the transmitter and its serving eNodeB, which heavily impacts the PDR achieved.

Purpose. This paper presents the innovative scientifically-based method on efficiency evaluation of the building production management for contracting companies. Otimisation models are substantially aimed at reducing the influence of negative factors and increasing the quality indexes of the organisational process of construction production. Methodology. Methodological approaches of the organisational processes optimisation of construction production are based on the establishment of a well-defined interconnection between the units of the functional structure, the definition of strategies hierarchy of the contracting company.The correlation of duration t and cost c in building production, its influence on the economic appropriateness for projects realisation in civil engineering are analyzed. Findings. Using mathematical analysing methods for cumulative distribution function S(t,c) of two-dimensional random value of construction duration and cost, the basic principles are shown that allow to qualitatively and quantitatively determine the level of influence of the construction market external factors on the implementation of organisational processes in the construction industry, in which a large number of forming elements are involved. The implementation of this methodology permits to assess the real state of organisational processes system in building production, its stability, the degree of determinate indicators structuring in a single functional system, to generate an economic justification in complex. On basis of simulation modeling, efficiency of organisational processes system in building production S(t,c) was determined and graphically illustrated. Originality. The results of the present study demonstrate that it amounted to 58.08 % within the established limits of acceptable risk (LAR) between 0.35 and 0.65. Practical value. It has been shown an implementation practicability of using this methodology by contracting companies at decision-making stage for construction projects initiation with determinate indicators of duration Td and cost Cd. The creation of theoretical and methodological foundations for the development of structural efficiency evaluation algorithms for the organisation of construction production will allow to achieve for contractor companies the highest level of competitiveness in the market of construction services.

Abstract:

-Security is a key factor to the development of any nation, yet it is a one major challenges faced all over the world. Several measures which ranges from key lock system to a highly intelligent lock system employed to restrict unwanted person to certain areas do have some level of limitations. This paper present the design of security lock using Radio frequency Identification (RFID) system and Global system for Mobile (GSM) communication technology aimed to address some of this limitation. The proposed lock system identifies a user by an RFID tag, authenticate it by sending 4digit codes to its mobile phone using short message services (SMS) and allow (confirm) the user to gain entrance if the correct code is entered. The program was written and builds to debug any error using Mikro C software. The circuit was designed using Proteus software and linked to the hex file generated by Mikro C to simulate. The simulation results were satisfactory which shows that real lock system will work according to design.

Abstract:

Since its emergence, cloud computing has continued to evolve thanks to its ability to present computing as consumable services paid by use, and the possibilities of resource scaling that it offers according to client’s needs. Models and appropriate schemes for resource scaling through consolidation service have been considerably investigated, mainly, at the infrastructure level to optimize costs and energy consumption. Consolidation efforts at the SaaS level remain very restrained mostly when proprietary software are in hand. In order to fill this gap and provide software licenses elastically regarding the economic and energy-aware considerations in the context of distributed cloud computing systems, this work deals with dynamic software consolidation in commercial cloud data centers 〖DS〗^3 C. Our solution is based on heuristic algorithms and allows reallocating software licenses at runtime by determining the optimal amount of resources required for their execution and freed unused machines. Simulation results showed the efficiency of our solution in terms of energy by 68.85% savings and costs by 80.01% savings. It allowed to free up to 75% physical machines and 76.5% virtual machines and proved its scalability in terms of average execution time while varying the number of software and the number of licenses alternately.

Abstract:

Abstract. An analysis to evaluate the impact of multiple radar reflectivity data with a three-dimensional variational (3-D-Var) assimilation system on a heavy precipitation event is presented. The main goal is to build a regionally tuned numerical prediction model and a decision-support system for environmental civil protection services and demonstrate it in the central Italian regions, distinguishing which type of observations, conventional and not (or a combination of them), is more effective in improving the accuracy of the forecasted rainfall. In that respect, during the first special observation period (SOP1) of HyMeX (Hydrological cycle in the Mediterranean Experiment) campaign several intensive observing periods (IOPs) were launched and nine of which occurred in Italy. Among them, IOP4 is chosen for this study because of its low predictability regarding the exact location and amount of precipitation. This event hit central Italy on 14 September 2012 producing heavy precipitation and causing several cases of damage to buildings, infrastructure, and roads. Reflectivity data taken from three C-band Doppler radars running operationally during the event are assimilated using the 3-D-Var technique to improve high-resolution initial conditions. In order to evaluate the impact of the assimilation procedure at different horizontal resolutions and to assess the impact of assimilating reflectivity data from multiple radars, several experiments using the Weather Research and Forecasting (WRF) model are performed. Finally, traditional verification scores such as accuracy, equitable threat score, false alarm ratio, and frequency bias – interpreted by analysing their uncertainty through bootstrap confidence intervals (CIs) – are used to objectively compare the experiments, using rain gauge data as a benchmark.

Abstract:

At the request of the Joint Program Office for intelligent transportation systems (ITS) of the FHWA, Mitretek Systems conducted a modeling analysis of ITS impacts in support of the metropolitan model deployment initiative evaluation program. The Mitretek modeling study supports the evaluation of the Seattle model deployment Smart Trek, testing a series of hypotheses that could not be addressed in controlled field studies or survey research. Using both a regional planning model and a subarea simulation, the study includes a series of experiments to quantify impacts from integrating ITS technologies and services both across jurisdictions and between functional components. The analysis addressed ( a) subarea-wide impacts of traffic signal coordination on major arterials, ( b) the impact of integrating arterial data into the current freeway-based advanced traveler information service (ATIS), and ( c) interactions at the corridor and the regional levels from concurrent deployment of signal coordination and the enhanced freeway and arterial ATIS. Results from that study have been summarized, detailing findings for a 300-km2 mixed freeway and arterial subarea network drawn from the roadway system north of downtown Seattle. The coordination of traffic signals along two major arterials resulted in a 7 percent reduction in overall subarea delay and a 3 percent reduction in total stops. More efficient route diversions for ATIS users result from the integration of arterial data into the current web-based service. At currently estimated levels of ATIS usage (6 percent of travelers), this improved diversion efficiency reduces overall subarea delay (users and nonusers) by over 3 percent.

Abstract:

Data are central to research, public health, and in developing health information technology (IT) systems. Nevertheless, access to most data in health care is tightly controlled, which may limit innovation, development, and efficient implementation of new research, products, services, or systems. Using synthetic data is one of the many innovative ways that can allow organizations to share datasets with broader users. However, only a limited set of literature is available that explores its potentials and applications in health care. In this review paper, we examined existing literature to bridge the gap and highlight the utility of synthetic data in health care. We searched PubMed, Scopus, and Google Scholar to identify peer-reviewed articles, conference papers, reports, and thesis/dissertations articles related to the generation and use of synthetic datasets in health care. The review identified seven use cases of synthetic data in health care: a) simulation and prediction research, b) hypothesis, methods, and algorithm testing, c) epidemiology/public health research, d) health IT development, e) education and training, f) public release of datasets, and g) linking data. The review also identified readily and publicly accessible health care datasets, databases, and sandboxes containing synthetic data with varying degrees of utility for research, education, and software development. The review provided evidence that synthetic data are helpful in different aspects of health care and research. While the original real data remains the preferred choice, synthetic data hold possibilities in bridging data access gaps in research and evidence-based policymaking.

Abstract:

With the continuous advancement of medicine and computer science, medical image processing technology is also constantly advancing, and at the same time, it puts forward the needs of its own development. The purpose of this article is to combine the three-dimensional reconstruction of medical images and virtual reality (VR) technology in nursing experiment teaching to help students understand more easily and to simplify the teachers’ teaching process and make the VR application technology. It is the most popular and effective in medical teaching. This article proposes the C-V model and the geometric active contour model to help us more clearly understand the pathology in this environment, where the specific symptoms appear, and bring a more easy-to-understand model for teaching and improving teaching quality. This article also designs nursing experiment teaching. The experimental results of this paper show that, after using VR courseware for teaching, the optimal test rate of the experimental class is 15% higher than that of the control class, and the transition rate is 8%. The actual test excellent rate and success rate of the experimental class are much higher than those of the control class. Therefore, it can be concluded that the application of VR technology in nursing teaching helps teachers improve their practical ability. The excellent teaching feedback rate is 95%, which is higher than 80.5% in the control group, indicating that the patient teaching simulation is approved by the observation group. The program can effectively improve the feedback rate of excellent teaching and provide students with better teaching services.

Abstract:

The worldwide COVID-19 pandemic has changed the development plans of every country. Instead, governments had to constantly deal with ever-emerging issues in healthcare, education, economics and industry. As a result, there has been an accelerated introduction of digitalization in these spheres. Thus, an increasing number of people have started using electronic services that have improved their digital literacy. This feature has had a positive impact on society and helped to create new interaction tools between populations and governments, students and institutions, customers and companies. The article aims to analyze how studying radio electronics can be improved by involving new tools and how they can be applied in distance learning. This work presents the results of the development and application of a virtual radio signal simulation in the educational process in the form of a laboratory practicum. Working on this approach required specific research in the field; the foreign experience was observed and studied. The review allowed us to find out how digitalization and the application of digital tools affect the behaviour, cognition, and overall performance of students during the pandemic. The authors conducted a questionnaire among students to evaluate the features of the virtual laboratory work and their effect on the educational process. The results analyzed are given in the article. They showed that students highly appreciate the introduction of such tools in learning. Moreover, like the entire laboratory, the proposed model can be used in the educational process offline and with distance learning. Finally, the article describes the experience and results of the software package’s development and integration for the spectrum analyzer’s computer model and virtual laboratory work using the MS VS environment in C ++. The results of the conducted work demonstrate the versatility of the proposed approach, its positive impact on the educational process, high potential in the other spheres.

Abstract:

The aim of this paper is to determine the most efficient strategic alternative in the case of a notary office, by taking into account the expected values associated to different levels of supplementary services requests by its customers. The determination of expected monetary values associated to the strategic alternatives by means of WinQSB software confirms the hypotheses concerning the feasibility analysis results and the manager’s ability to make the right decision from the financial point of view. Thus, the manager of the notary office will be able to make efficient decisions regarding the business development plan by using appropriate software tools, which deliver real time results in different simulation scenarios. Once the optimal decision is found, the notary office can seek to improve its business development strategy by taking into account more options and levels of supplementary services requests from the part of its customers.

Abstract:

Energy, power, lifetime and safety of Lithium ion batteries (LIBs) are determined in part by the internal microstructure of the electrodes. That microstructure is characterized by the spatial location and the resulting interfaces between the active material particles, the conductive additive, the binder and the pores. The microstructure is determined by the manufacturing process of the electrodes, which encompasses, in its traditional wet form, multiple steps and numerous parameters. Therefore, its optimization is difficult and can be time consuming and costly if carried out only on the basis of a trial and error approach. In this lecture I discuss a digital infrastructure for accelerated optimization of the manufacturing process of LIBs that we are developing since few years: ARTISTIC.1 Such digital infrastructure is supported on a hybrid approach encompassing a physics-based multiscale modeling workflow, Artificial Intelligence (AI)/machine learning models and high throughput experimental characterizations.2 ARTISTIC simulates different steps along the battery cells manufacturing process, such as the electrode slurry preparation, the coating, the drying, the calendering and the electrolyte infiltration. For that purpose, it uses a combination of sequentially-coupled 3D-resolved physical models based on experimentally-validated Coarse Grained Molecular Dynamics, Discrete Element Method and Lattice Boltzmann Method. This allows predicting the impact of the manufacturing process parameters on the final electrode microstructure in three dimensions. The predicted electrode microstructures are then injected in a continuum performance simulator capturing the influence of the electrode microstructure on the solid electrolyte interphase formation (for anodes) and the electrochemical response (of anodes vs. lithium, cathodes vs. lithium and the full cells). Machine learning models are used to unravel manufacturing parameters interdependencies from the physical models’ predictions and experimental data, and to suggest manufacturing process optimizations. The predictive capabilities and chemistry-neutrality of the ARTISTIC digital infrastructure are illustrated with results for different LIB electrode formulations and chemistries (NMC, LFP, graphite, silicon/graphite blends) and also for organic active materials for sodium ion batteries. Finally, I discuss the free online battery manufacturing simulation services (online caculator and associated databases) offered by our project and that you can use interactively from your Internet Browser.3 References: [1] ERC Consolidator Project ARTISTIC, grant agreement #772873 ( https://www.erc-artistic.eu/ ).

Abstract:

This paper summarizes the main theoretical points within the scientific discussion on the issue of digitalization in Mass Customization concept and online Mass Customization frameworks. Origins of a stand-alone Mass Customization concept drawback to the second half of the 1990s, but major theoretical content changes and development have been identified in the last 2 decades. An intensive application of combined technology and management solutions, digital society and business transformations in the past decade has shifted the orientation of the concept to intangible products management, customer involvement and mutual value creation via frameworks in the online environment. The main purpose of the research is to reveal and present the role and impact of the digitalization sub-domain to the Mass Customization concept, its transition to the e-concept version and modelling of new combined online customization frameworks. The decision relevance of this scientific problem is multiple issues in transitions of practical organizations to the modern and mixed technological-management approach-based Mass Customization version as well as application limitations of existing online customization frameworks. The analysis of the research topic is carried out in the logical sequence. Firstly, the author presented the influence of the digitalization sub-domain to theoretical transformations of traditional Mass Customization concept. Then, a case study of the organizational transition to electronic Mass Customization and Personalization and online customization frameworks was conducted. Methodological tools and research methods used in the paper have been integrative literature review and narrative synthesis of qualitative findings of 53 articles, and a simplified Robinson conceptual modelling framework together with a c-tuple method for the simulation of new combined online customization frameworks. The research empirically confirms and theoretically proves that within last decade both practical and academic attention to sustainable and agile development of new, fully digital customized products and personalized services as well as flexible online customization frameworks and solutions significantly have increased. Furthermore, here the extent by 6 new online customization frameworks is offered next to 3 standard theoretical online customization frameworks, which became difficult to apply in the environment and preferences of modern e-business organizations and digital end-users. The results of the research can be useful for continuous scientific researches to test and validate 6 new online customization frameworks in a feedback loop part and evaluate the influence of these frameworks to a digital end-user behaviour, their role in frameworks and attitude aspects.

Abstract:

With the emerging vehicular network and the possible diverse applications, intelligent transportation systems (ITS) have been evolving to Cooperative ITS (C-ITS) with connected intelligent vehicles, and the topics in this field have raised more and more research interests recently. However, subjecting to the immaturity of V2X communication technology, the difficulty and high cost to deploy such large scale ITS with intelligent vehicles, emerging studies are stuck with the verification of these big C-ITS. As more and more expected, intelligent vehicles will play important roles in the future smart cities and societies, as diverse mobility carriers. Focusing on new features of these carriers, mainly covering cyber-physical fusion, vehicular networking, service-carrier and so on, one new ITS simulator QoS-CITS for such service-oriented C-ITS is designed and developed. To enhance the adaptability, a scenario reconfigurable architecture is firstly designed, in which scenes can be described via XML file. On this basis, the authors have implemented all reservation-based models of traffic objects, state-driven behaviors, cooperation mechanisms, and policies, which are proposed for service-oriented C-ITS. Through a series of experiments are conducted with different parameters and typical scenes, all simulation functions are efficiently verified. And finally, some important conclusions drawn from large amount of experiments via QoS-CITS are exhibited. It's important to note that, researchers can conduct various experiments, both the traditional Passing-Through-Intersection (PTI) problem and service-oriented cooperation, via setting parameters of QoS-CITS according to their requirements, and can also analyze the performance with statistics data recorded automatically.

Abstract:

People make mundane and critical consumption decisions every day using choice processes that are inherently constructive in nature, where preferences emerge ‘on the spot’ or ‘on the go’ using multiple strategies based on the task at hand (Bettman, Luce, & Payne, 1998; Sproule & Archer, 2000). This implies that applying a single, invariant algorithm will not solve decision problems that humans face (Tversky, Sattath, & Slovic, 1988). Instead, consumers need adaptive, multi-strategy decision aids since they shift between multiple strategies in a single decision as they acquire increasing information during the decision-making process (Bettman et al., 1998). This paper puts forth a cognitive computing approach to develop and validate a naturalistic decision model for designing language-based, mobile decision-aids (MoDA©) based on adaptive and intelligent information retrieval and multi-decision strategy use. The approach integrates established psychological theories, Elaboration Likelihood Model (ELM) and Construal Level Theory (CLT), to develop the scientific base for predicting decision-making under contingencies. ELM delineates whether human information processing is effortful or heuristic based on a person’s ability and motivation to engage in an object-relevant elaboration (Petty & Cacioppo, 1981). CLT determines whether the cognitive construal of the decision object is abstract or concrete based on psychological distance (Liberman, Trope, & Wakslak, 2007). Integrating the derivatives of these theories, the Human-Elaboration-Object-Construal (H-E-O-C) Contingency Decision Model’s central thesis is that the decision-making strategy employed by a decision-maker can be predicted by using natural language cues to infer the extent of human elaboration (low-high) on the decision and the type of knowledge (abstract-concrete) possessed on the decision object. Specifically, an extensive (vs. limited) decision strategy is likely to be employed when human elaboration revealed through natural language cues is high (vs. low). Further, an attribute-based (vs. alternative-based) strategy may be employed when the cognitive representation of the decision object is abstract (vs. concrete). Based on this theorizing, the H-E-O-C Contingency Decision Model can predict the use of four common decision strategies that systematically differ based on the amount (extensive vs. limited) and pattern (attribute- vs. alternative-based) of processing: Lexicographic or LEX (limited, attribute-based processing), Satisficing or SAT (limited, alternative-based processing), Elimination-by-Aspects or EBA (extensive, attribute-based processing), and Weighted Adding or WADD (extensive, alternative-based processing) (Bettman et al., 1998). To validate the H-E-O-C Contingency Decision Model, we conducted observational studies that simulated in-store purchase decision-making with real consumers. A total of 48 shopping sessions (n = 48) were held in a simulation home improvement retail store, and decision-making dialog between consumers and a customer service agent (trained research assistant) was recorded using wearable voice recorders. To ensure that there were fairly equal numbers of consumers who were either motivated or not to elaborate on their decisions, we created two shopping conditions – low risk (replacement AC filter purchase) and high risk (AC filter purchase to address allergy and asthma). The recorded decision dialogs were first transcribed verbatim, resulting 48 units of analysis, which were then analyzed using the grounded theory approach through open and axial coding processes (Corbin & Strauss, 1990). The open coding first identified the construal level, which was followed by axial coding to infer the decision strategy (LEX, EBA, SAT, or WADD) employed by the consumer at the initial and final stages of decision-making. This process was conducted by two coders with adequate inter-coder reliability. Two different coders coded the transcripts for the elaboration level (low vs. high) of the consumer based on specific definitions, with adequate inter-coder reliability. The H-E-O-C Contingency Decision Model proposes that high elaboration consumers will employ either WADD or EBA, whereas low elaboration consumers will employ either SAT or LEX. This proposition was supported in over 80% of the decision transcripts, offering an important validation of the framework. The main contribution of the H-E-O-C Contingency Decision Model is that it is derived from universal psychological constructs and predicts decision-making strategies that apply to many types of products and services related to healthcare, education, and finance that are characterized by attributes and alternatives. This ensures its broad applicability across a wide variety of disciplines and use cases.

Abstract:

Abstract Cloud computing is continuing to prove its flexibility and versatility in helping industries and businesses as well as academia as a way of providing needed computing capacity. As an important alternative to cloud computing, desktop grids allow to utilize the idle computer resources of an enterprise/community by means of distributed computing system, providing a more secure and controllable environment with lower operational expenses. Further, both cloud computing and desktop grids are meant to optimize limited resources and at the same time to decrease the expected latency for users. The crucial parameter for optimization both in cloud computing and in desktop grids is the level of redundancy (replication) for service requests/workunits. In this paper we study the optimal replication policies by considering three variations of Fork-Join systems in the context of a multi-server queueing system with a versatile point process for the arrivals. For services we consider phase type distributions as well as shifted exponential and Weibull. We use both analytical and simulation approach in our analysis and report some interesting qualitative results.

Abstract:

Recent Trends and Future of Fog and Edge Computing, Services, and Enabling Technologies Cloud computing has been established as the most popular as well as suitable computing infrastructure providing on-demand, scalable and pay-as-you-go computing resources and services for the state-of-the-art ICT applications which generate a massive amount of data. Though Cloud is certainly the most fitting solution for most of the applications with respect to processing capability and storage, it may not be so for the real-time applications. The main problem with Cloud is the latency as the Cloud data centres typically are very far from the data sources as well as the data consumers. This latency is ok with the application domains such as enterprise or web applications, but not for the modern Internet of Things (IoT)-based pervasive and ubiquitous application domains such as autonomous vehicle, smart and pervasive healthcare, real-time traffic monitoring, unmanned aerial vehicles, smart building, smart city, smart manufacturing, cognitive IoT, and so on. The prerequisite for these types of application is that the latency between the data generation and consumption should be minimal. For that, the generated data need to be processed locally, instead of sending to the Cloud. This approach is known as Edge computing where the data processing is done at the network edge in the edge devices such as set-top boxes, access points, routers, switches, base stations etc. which are typically located at the edge of the network. These devices are increasingly being incorporated with significant computing and storage capacity to cater to the need for local Big Data processing. The enabling of Edge computing can be attributed to the Emerging network technologies, such as 4G and cognitive radios, high-speed wireless networks, and energy-efficient sophisticated sensors. Different Edge computing architectures are proposed (e.g., Fog computing, mobile edge computing (MEC), cloudlets, etc.). All of these enable the IoT and sensor data to be processed closer to the data sources. But, among them, Fog computing, a Cisco initiative, has attracted the most attention of people from both academia and corporate and has been emerged as a new computing-infrastructural paradigm in recent years. Though Fog computing has been proposed as a different computing architecture than Cloud, it is not meant to replace the Cloud. Rather, Fog computing extends the Cloud services to network edges for providing computation, networking, and storage services between end devices and data centres. Ideally, Fog nodes (edge devices) are supposed to pre-process the data, serve the need of the associated applications preliminarily, and forward the data to the Cloud if the data are needed to be stored and analysed further. Fog computing enhances the benefits from smart devices operational not only in network perimeter but also under cloud servers. Fog-enabled services can be deployed anywhere in the network, and with these services provisioning and management, huge potential can be visualized to enhance intelligence within computing networks to realize context-awareness, high response time, and network traffic offloading. Several possibilities of Fog computing are already established. For example, sustainable smart cities, smart grid, smart logistics, environment monitoring, video surveillance, etc. To design and implementation of Fog computing systems, various challenges concerning system design and implementation, computing and communication, system architecture and integration, application-based implementations, fault tolerance, designing efficient algorithms and protocols, availability and reliability, security and privacy, energy-efficiency and sustainability, etc. are needed to be addressed. Also, to make Fog compatible with Cloud several factors such as Fog and Cloud system integration, service collaboration between Fog and Cloud, workload balance between Fog and Cloud, and so on need to be taken care of. It is our great privilege to present before you Volume 20, Issue 2 of the Scalable Computing: Practice and Experience. We had received 20 Research Papers and out of which 14 Papers are selected for Publication. The aim of this special issue is to highlight Recent Trends and Future of Fog and Edge Computing, Services and Enabling technologies. The special issue will present new dimensions of research to researchers and industry professionals with regard to Fog Computing, Cloud Computing and Edge Computing. Sujata Dash et al. contributed a paper titled “Edge and Fog Computing in Healthcare- A Review” in which an in-depth review of fog and mist computing in the area of health care informatics is analysed, classified and discussed. The review presented in this paper is primarily focussed on three main aspects: The requirements of IoT based healthcare model and the description of services provided by fog computing to address then. The architecture of an IoT based health care system embedding fog computing layer and implementation of fog computing layer services along with performance and advantages. In addition to this, the researchers have highlighted the trade-off when allocating computational task to the level of network and also elaborated various challenges and security issues of fog and edge computing related to healthcare applications. Parminder Singh et al. in the paper titled “Triangulation Resource Provisioning for Web Applications in Cloud Computing: A Profit-Aware” proposed a novel triangulation resource provisioning (TRP) technique with a profit-aware surplus VM selection policy to ensure fair resource utilization in hourly billing cycle while giving the quality of service to end-users. The proposed technique use time series workload forecasting, CPU utilization and response time in the analysis phase. The proposed technique is tested using CloudSim simulator and R language is used to implement prediction model on ClarkNet weblog. The proposed approach is compared with two baseline approaches i.e. Cost-aware (LRM) and (ARMA). The response time, CPU utilization and predicted request are applied in the analysis and planning phase for scaling decisions. The profit-aware surplus VM selection policy used in the execution phase for select the appropriate VM for scale-down. The result shows that the proposed model for web applications provides fair utilization of resources with minimum cost, thus provides maximum profit to application provider and QoE to the end users. Akshi kumar and Abhilasha Sharma in the paper titled “Ontology driven Social Big Data Analytics for Fog enabled Sentic-Social Governance” utilized a semantic knowledge model for investigating public opinion towards adaption of fog enabled services for governance and comprehending the significance of two s-components (sentic and social) in aforesaid structure that specifically visualize fog enabled Sentic-Social Governance. The results using conventional TF-IDF (Term Frequency-Inverse Document Frequency) feature extraction are empirically compared with ontology driven TF-IDF feature extraction to find the best opinion mining model with optimal accuracy. The results concluded that implementation of ontology driven opinion mining for feature extraction in polarity classification outperforms the traditional TF-IDF method validated over baseline supervised learning algorithms with an average of 7.3% improvement in accuracy and approximately 38% reduction in features has been reported. Avinash Kaur and Pooja Gupta in the paper titled “Hybrid Balanced Task Clustering Algorithm for Scientific workflows in Cloud Computing” proposed novel hybrid balanced task clustering algorithm using the parameter of impact factor of workflows along with the structure of workflow and using this technique, tasks can be considered for clustering either vertically or horizontally based on value of impact factor. The testing of the algorithm proposed is done on Workflowsim- an extension of CloudSim and DAG model of workflow was executed. The Algorithm was tested on variables- Execution time of workflow and Performance Gain and compared with four clustering methods: Horizontal Runtime Balancing (HRB), Horizontal Clustering (HC), Horizontal Distance Balancing (HDB) and Horizontal Impact Factor Balancing (HIFB) and results stated that proposed algorithm is almost 5-10% better in makespan time of workflow depending on the workflow used. Pijush Kanti Dutta Pramanik et al. in the paper titled “Green and Sustainable High-Performance Computing with Smartphone Crowd Computing: Benefits, Enablers and Challenges” presented a comprehensive statistical survey of the various commercial CPUs, GPUs, SoCs for smartphones confirming the capability of the SCC as an alternative to HPC. An exhaustive survey is presented on the present and optimistic future of the continuous improvement and research on different aspects of smartphone battery and other alternative power sources which will allow users to use their smartphones for SCC without worrying about the battery running out. Dhanapal and P. Nithyanandam in the paper titled “The Slow HTTP Distributed Denial of Service (DDOS) Attack Detection in Cloud” proposed a novel method to detect slow HTTP DDoS attacks in cloud to overcome the issue of consuming all available server resources and making it unavailable to the real users. The proposed method is implemented using OpenStack cloud platform with slowHTTPTest tool. The results stated that proposed technique detects the attack in efficient manner. Mandeep Kaur and Rajni Mohana in the paper titled “Static Load Balancing Technique for Geographically partitioned Public Cloud” proposed a novel approach focused upon load balancing in the partitioned public cloud by combining centralized and decentralized approaches, assuming the presence of fog layer. A load balancer entity is used for decentralized load balancing at partitions and a controller entity is used for centralized level to balance the overall load at various partitions. Results are compared with First Come First Serve (FCFS) and Shortest Job First (SJF) algorithms. In this work, the researchers compared the Waiting Time, Finish Time and Actual Run Time of tasks using these algorithms. To reduce the number of unhandled jobs, a new load state is introduced which checks load beyond conventional load states. Major objective of this approach is to reduce the need of runtime virtual machine migration and to reduce the wastage of resources, which may be occurring due to predefined values of threshold. Mukta and Neeraj Gupta in the paper titled “Analytical Available Bandwidth Estimation in Wireless Ad-Hoc Networks considering Mobility in 3-Dimensional Space” proposes an analytical approach named Analytical Available Bandwidth Estimation Including Mobility (AABWM) to estimate ABW on a link. The major contributions of the proposed work are: i) it uses mathematical models based on renewal theory to calculate the collision probability of data packets which makes the process simple and accurate, ii) consideration of mobility under 3-D space to predict the link failure and provides an accurate admission control. To test the proposed technique, the researcher used NS-2 simulator to compare the proposed technique i.e. AABWM with AODV, ABE, IAB and IBEM on throughput, Packet loss ratio and Data delivery. Results stated that AABWM performs better as compared to other approaches. R.Sridharan and S. Domnic in the paper titled “Placement Strategy for Intercommunicating Tasks of an Elastic Request in Fog-Cloud Environment” proposed a novel heuristic IcAPER,(Inter-communication Aware Placement for Elastic Requests) algorithm. The proposed algorithm uses the network neighborhood machine for placement, once current resource is fully utilized by the application. The performance IcAPER algorithm is compared with First Come First Serve (FCFS), Random and First Fit Decreasing (FFD) algorithms for the parameters (a) resource utilization (b) resource fragmentation and (c) Number of requests having intercommunicating tasks placed on to same PM using CloudSim simulator. Simulation results shows IcAPER maps 34% more tasks on to the same PM and also increase the resource utilization by 13% while decreasing the resource fragmentation by 37.8% when compared to other algorithms. Velliangiri S. et al. in the paper titled “Trust factor based key distribution protocol in Hybrid Cloud Environment” proposed a novel security protocol comprising of two stages: first stage, Group Creation using the trust factor and develop key distribution security protocol. It performs the communication process among the virtual machine communication nodes. Creating several groups based on the cluster and trust factors methods. The second stage, the ECC (Elliptic Curve Cryptography) based distribution security protocol is developed. The performance of the Trust Factor Based Key Distribution protocol is compared with the existing ECC and Diffie Hellman key exchange technique. The results state that the proposed security protocol has more secure communication and better resource utilization than the ECC and Diffie Hellman key exchange technique in the Hybrid cloud. Vivek kumar prasad et al. in the paper titled “Influence of Monitoring: Fog and Edge Computing” discussed various techniques involved for monitoring for edge and fog computing and its advantages in addition to a case study based on Healthcare monitoring system. Avinash Kaur et al. elaborated a comprehensive view of existing data placement schemes proposed in literature for cloud computing. Further, it classified data placement schemes based on their assess capabilities and objectives and in addition to this comparison of data placement schemes. Parminder Singh et al. presented a comprehensive review of Auto-Scaling techniques of web applications in cloud computing. The complete taxonomy of the reviewed articles is done on varied parameters like auto-scaling, approach, resources, monitoring tool, experiment, workload and metric, etc. Simar Preet Singh et al. in the paper titled “Dynamic Task Scheduling using Balanced VM Allocation Policy for Fog Computing Platform” proposed a novel scheme to improve the user contentment by improving the cost to operation length ratio, reducing the customer churn, and boosting the operational revenue. The proposed scheme is learnt to reduce the queue size by effectively allocating the resources, which resulted in the form of quicker completion of user workflows. The proposed method results are evaluated against the state-of-the-art scene with non-power aware based task scheduling mechanism. The results were analyzed using parameters-- energy, SLA infringement and workflow execution delay. The performance of the proposed schema was analyzed in various experiments particularly designed to analyze various aspects for workflow processing on given fog resources. The LRR (35.85 kWh) model has been found most efficient on the basis of average energy consumption in comparison to the LR (34.86 kWh), THR (41.97 kWh), MAD (45.73 kWh) and IQR (47.87 kWh). The LRR model has been also observed as the leader when compared on the basis of number of VM migrations. The LRR (2520 VMs) has been observed as best contender on the basis of mean of number of VM migrations in comparison with LR (2555 VMs), THR (4769 VMs), MAD (5138 VMs) and IQR (5352 VMs).

Abstract:

Technical analysis of intellectual property (IP) is conducted for the purpose of legal protection and product development. A brief review of the process of IP analysis and associated terminology is provided along with examples illustrating the significant potential for monetary benefits to be derived. The evolution of the reverse engineering (RE) process in the semiconductor industry is briefly reviewed from a historical perspective. It is shown how the objective of RE, while continuing its traditional engagement in IP protection, has shifted away from “second sourcing” activities to become an active participant by providing valuable services to technology and product development. The assertion is made that the negative connotation often associated with “reverse engineering” is no longer justified; and the legitimacy, usefulness, and respectability of that process is reaffirmed. The effects of international diffusion of technology are described. It is shown that being aware of technology content in competing high-tech products is now greater than ever before. The process of RE and the “toolbox” of career IP analysts are described through the analysis example of an advanced SOC and SIP structure. The dual utility of the analyst's toolbox and skill set is examined as it is being applied a) to the discovery process aimed at intellectual property protection and b) as a means to accelerate product development. Special attention is given to technical IP analysis conducted in association with new product research and development. Practical examples involving the analysis of advanced 3D structures are provided from the field of 3D integrated product development in order to demonstrate how technical IP analysis can a) help avoid costly mistakes, b) capture design wins, and c) accelerate new product development. The synergistic relationship between IP analysis applied to IP protection and product development is explored; and a coordinated and comprehensive approach to technical IP analysis is recommended whenever practical. A high-tech company will realize maximum benefits from a technical analyst's work if IP analysis of competing products is performed for the purpose of product development with the analyst remaining mindful and attentive of the need to protect corporate patent portfolio. Conversely, knowledge gained from technical analysis aimed at protecting the company's patents can be quite useful to the development engineer. Regardless of whether or not the analyst is an employee of the company or a hired sub-contractor, proper description of the task is crucial from the outset. The analyst should be encouraged to take a dual track approach with primary focus directed towards the main intent (IP protection or engineering analysis of a competing product or technology) without ignoring the secondary purpose. At the end of a project, an assessment should be made as to what part of the acquired knowledge is relevant to the engineering community and what portion of the report needs to be directed to the IP department. Technical IP analysis conducted with this dual purpose in mind is a cost-effective way to maximize return on investment (ROI) in RE. It can also be a powerful tool to reduce the cost of new product development while improving time to market. A new area of technical IP analysis, the extraction of parasitic R, L, C elements from SOC and SIP structures, is explored in detail. This field is believed to be of great importance in 3D integration due to the loss or breakup of ground and power delivery planes as a result of increased reliance on vertical interconnections such as interposers and TSVs. These structures introduce troublesome interconnect inductances, resistances, and capacitances. Both power distribution networks (PDN) and high-speed signal paths are affected by interconnect parasitic elements in component modules such as deep sub-micron 22nm ARM processors, multi-stack memories, and multilayer PCBs of high speed communication devices and systems. It is essential for circuit designers, package designers, and system designers to be aware of these risks as early in the design phase as possible. Practical examples are given how an entire PDN of a larger system including complex 2.5D and 3D packages, substrates, and PCB can be reconstructed from the power source down to individual components, including high-speed data paths. Such reconstruction is done using two-dimensional layer images and via structures. The reconstructed file can be 2D or 3D representation. Depending on the objective, the data residing in those files is then imported into state-of-the art circuit simulation tools familiar to the circuit or package designer. At that point, the circuit, package, or system designer can analyze the entire system and extract all parasitic interconnect elements. The circuit designer can then incorporate all those interconnect and passive component parasitic R, L, C, and M elements or their S-parameter representation into a top-level circuit simulation of an integrated circuit and obtain an accurate circuit performance that is truly representative of the final hardware. In summary, the need for precise modeling of the PDN section and certain high-speed data paths of SOC and SIP structures is reaffirmed, and a case is made for making this sometimes labor intensive process available as part of the technical analysis process. The synergy between reverse engineering conducted for the purpose of IP protection and product development is further emphasized. It is concluded that technical IP analysis, competitor product (hardware) analysis, and product development are activities complementary to one another. These activities, if executed thoughtfully, consistently, and systematically, can not only protect IP, increase intellectual asset value, but can also accelerate product development, guide and fuel innovation, and help in setting the direction of research and development.

Abstract:

A service system with multiple types of arriving customers is considered. There is an infinite number of homogeneous servers. Multiple customers can be placed for simultaneous service into one server, subject to general packing constraints. The service times of different customers are independent even if they are served simultaneously by the same server; the service time distribution depends on the customer type. Each new arriving customer is placed for service immediately into either an occupied server, that is, one already serving other customers, as long as packing constraints are not violated or into an empty server. After service completion, each customer leaves its server and the system. The basic objective is to minimize the number of occupied servers in steady state. We study a greedy random (GRAND) placement (packing) algorithm, introduced in our previous work. This is a simple online algorithm that places each arriving customer uniformly at random into either one of the already occupied servers that can still fit the customer or one of the so-called zero servers, which are empty servers designated to be available to new arrivals. In our previous work, a version of the algorithm, labeled GRAND(aZ), is considered, in which the number of zero servers is aZ with Z being the current total number of customers in the system and positive a being an algorithm parameter. GRAND(aZ) is shown in our previous work to be asymptotically optimal in the following sense: (a) the steady-state optimality gap grows linearly in the system scale r (the mean total number of customers in service), that is, as c(a)r for some positive c(a), and (b) c(a) vanishes as a goes to zero. In this paper, we consider the GRAND(Z p ) algorithm, in which the number of zero servers is Z p , where p < 1 is a fixed parameter, sufficiently close to 1. We prove the asymptotic optimality of GRAND(Z p ) in the sense that the steady-state optimality gap is sublinear in the system scale r. This is a stronger form of asymptotic optimality than that of GRAND(aZ).

Abstract:

Livestock grazing occupies ca. 25% of global ice-free land, removing large quantities of carbon (C) from global rangelands (here, including grass- and shrublands). The proportion of total livestock intake that is supplied by grazing (GP) is estimated at >50%, larger than the proportion from crop- and byproduct-derived fodders. Both rangeland productivity and its consumption through grazing are difficult to quantify, as is grazing intensity (GI), the proportion of annual aboveground net primary productivity (ANPP) removed from rangelands by grazing livestock. We develop national or sub-national level estimates of GI and GP for 2000–2010, using remote sensing products, inventory data, and model simulations, and accounting for recent changes in livestock intake, fodder losses and waste, and national cropland use intensities. Over the 11 study years, multi-model average global rangeland ANPP varied between the values of 13.0 Pg C in 2002 and 13.96 Pg C in 2000. The global requirement for grazing intake increased monotonically by 18%, from 1.54 in 2000 to 1.82 Pg C in 2010. Although total global rangeland ANPP is roughly an order of magnitude larger than grazing demand, much of this total ANPP is unavailable for grazing, and national or sub-national deficits between intake requirements and available rangeland ANPP occurred in each year, totaling 36.6 Tg C (2.4% of total grazing intake requirement) in 2000, and an unprecedented 77.8 Tg C (4.3% of global grazing intake requirement) in 2010. After accounting for these deficits, global average GI ranged from 10.7% in 2000 to 12.6% in 2009 and 2010. The annually increasing grazing deficits suggest that rangelands are under significant pressure to accommodate rising grazing demand. Greater focus on observing, understanding, and managing the role of rangelands in feeding livestock, providing ecosystem services, and as part of the global C cycle, is warranted.

Abstract:

Blue-green infrastructure (BGI) is defined as a strategically planned network of natural and semi-natural areas with other environmental features designed and managed to deliver a wide range of ecosystem services, which include microclimate regulation and enhanced human thermal comfort. While green infrastructure is widely known to be capable of mitigating the adverse effects of urban heat island, the effect of blue infrastructure to regulate thermal comfort is still poorly understood. This study investigates several blue-green-infrastructure (BGI) scenarios in the central business district (CBD) of Melbourne, Australia to assess their effects on microclimate and human thermal comfort. Three-dimensional microclimatic modelling software, ENVI-met, was used to simulate the microclimate and human thermal comfort. Physiological equivalent temperature (PET) was used to quantify the level of thermal comfort in selected research areas. Ten different scenarios were simulated, which included those based on green roofs, green walls, trees, ponds and fountains. The simulations suggest that green roofs and green walls in the high-rise building environment have a small temperature reduction in its surrounding area by up to 0.47 °C and 0.27 °C, respectively, and there is no noticeable improvement in the level of thermal perception. The tree-based scenarios decrease temperature by up to 0.93 °C and improve the thermal perception from hot to warm. Scenarios based on water bodies and fountains decrease the temperature by up to 0.51 °C and 1.48 °C, respectively, yet they cannot improve the thermal perception of the area. A deeper water body has a better microclimate improvement as compared to a shallow one. The temperature reduction in the fountain scenario tends to be local and the effect could only be felt within a certain radius from the fountain.

Abstract:

Unmanned aerial vehicles (UAVs), also known as drones, are important for several application domains, such as the military, agriculture, cultural heritage documentation, surveillance, and the delivery of goods/products/services. A drone’s trajectory can be enriched with external and heterogeneous data beyond latitude, longitude, and timestamp to create its semantic trajectory, providing meaningful and contextual information on its movement data, enabling decision makers to acquire meaningful and enriched contextual information about the current situation in the field of its operation and eventually supporting simulations and predictions of high-level critical events. In this paper, we present an ontology-based, tool-supported framework for the reconstruction, modeling, and enrichment of drones’ semantic trajectories. This framework extends MovingPandas, a widely used and open-source trajectory analytics and visualization tool. The presented research extends our preliminary work on drones’ semantic trajectories by contributing (a) an updated methodology for the reconstruction of drones’ trajectories from geo-tagged photos taken by drones during their flights in cases in which flight plans and/or real-time movement data have been lost or corrupted; (b) an enrichment of the reconstructed trajectories with external data; (c) the semantic annotation of the enriched trajectories based on a related ontology; and (d) the use of SPARQL queries to analyze and retrieve knowledge related to the flight of a drone and the field of operations (context). An evaluation of the presented framework, namely, ReconTraj4Drones, was conducted against several criteria, using real and open datasets.

Abstract:

A gas turbine (GT) blade is a key hot-pass component for advanced GT engines, and should have stable properties under extreme conditions of 1,350°C and 3,600rpm, etc. The GT blade, after operating with nearly 800 equivalent start-stops (ES) or 24,000 equivalent operation hours (EOH), should be replaced due to degradation of properties and microstructure, particularly, the formation of cracks in the airfoil tip and platform region. To date, the assessment of materials, prototype blade, etc, has been extensively studied in a laboratory simulated environment; however, evaluation of the full-scale blades in a service environment has been rarely reported. Here, the properties and microstructures of an F-class GT first stage blade, with a service history of 800ES were investigated. The results showed decreasing tensile properties at the airfoil part due to its higher temperature exposure. The microstructural characterization results revealed that the finer grain size and dendrite interfaces facilitated the formation of Cr-enriched M<sub>23</sub>C<sub>6</sub> along grain boundaries, as well as the spherical γ' in the airfoil part, resulting in a decrease in tensile properties. The results obtained here provide precious background for assessing the serviced blade and developing advanced blades.

Abstract:

The study demonstrated that spatial analysis with relevant socio-economic sources and physical parameter from different sources can be evaluated for the filling station sites planning. This has demonstrated the importance of Geographic Information System (GIS) application in predicting and determining of site criteria for filling stations facilities development, most especially in areas where there is land uses competition which requires consumer accessibility, sustainability, environmental safety, environmentally sensitive development solutions, etc. A stratified sampling technique was used to select the sample size and administration of the questionnaire. The data collected was analyzed using descriptive statistics such as frequency distribution, bar chart, pie chart and percentage and maps showing the sampled existing filling stations in the study area. The result shows the distribution of filling stations located across the study area. This study shows that GIS and multi-criteria analysis are essential tools to assist in correct siting to national planners and decision-makers in deciding the most appropriate filling stations location pattern to apply in Minna and its environs.

Abstract:

Objectives:Determine the relationship between quality of an accountable care organization (ACO) and its long-term reduction in healthcare costs.Methods:We conducted a cost minimization analysis. Using Centers for Medicare and Medicaid cost and quality data, we calculated weighted composite quality scores for each ACO and organization-level cost savings. We used Markov modeling to compute the probability that an ACO transitioned between different quality levels in successive years. Considering a health-systems perspective with costs discounted at 3 percent, we conducted 10,000 Monte Carlo simulations to project long-term cost savings by quality level over a 10-year period. We compared the change in per-member expenditures of Pioneer (early-adopters) ACOs versus Medicare Shared Savings Program (MSSP) ACOs to assess the impact of coordination of care, the main mechanism for cost savings.Results:Overall, Pioneer ACOs saved USD 641.24 per beneficiary and MSSP ACOs saved USD 535.59 per beneficiary. By quality level: (a) high quality organizations saved the most money (Pioneer: USD 459; MSSP: USD 816); (b) medium quality saved some money (Pioneer: USD 222; MSSP: USD 105); and (c) low quality suffered financial losses (Pioneer: USD -40; MSSP: USD -386).Conclusions:Within the existing fee-for-service healthcare model, ACOs are a mechanism for decreasing costs by improving quality of care. Higher quality organizations incorporate greater levels of coordination of care, which is associated with greater cost savings. Pioneer ACOs have the highest level of integration of services; hence, they save the most money.

Abstract:

Abstract. The mechanistic model GO+ describes the functioning and growth of managed forests based upon biophysical and biogeochemical processes. The biophysical and biogeochemical processes included are modelled using standard formulations of radiative transfer, convective heat exchange, evapotranspiration, photosynthesis, respiration, plant phenology, growth and mortality, biomass nutrient content, and soil carbon dynamics. The forest ecosystem is modelled as three layers, namely the tree overstorey, understorey and soil. The vegetation layers include stems, branches and foliage and are partitioned dynamically between sunlit and shaded fractions. The soil carbon submodel is an adaption of the Roth-C model to simulate the impact of forest operations. The model runs at an hourly time step. It represents a forest stand covering typically 1 ha and can be straightforwardly upscaled across gridded data at regional, country or continental levels. GO+ accounts for both the immediate and long-term impacts of forest operations on energy, water and carbon exchanges within the soil–vegetation–atmosphere continuum. It includes exhaustive and versatile descriptions of management operations (soil preparation, regeneration, vegetation control, selective thinning, clear-cutting, coppicing, etc.), thus permitting the effects of a wide variety of forest management strategies to be estimated: from close to nature to intensive. This paper examines the sensitivity of the model to its main parameters and estimates how errors in parameter values are propagated into the predicted values of its main output variables.The sensitivity analysis demonstrates an interaction between the sensitivity of variables, with the climate and soil hydraulic properties being dominant under dry conditions but the leaf biochemical properties being most influential with wet soil. The sensitivity profile of the model changes from short to long timescales due to the cumulative effects of the fluxes of carbon, energy and water on the stand growth and canopy structure. Apart from a few specific cases, the model simulations are close to the values of the observations of atmospheric exchanges, tree growth, and soil carbon and water stock changes monitored over Douglas fir, European beech and pine forests of different ages. We also illustrate the capacity of the GO+ model to simulate the provision of key ecosystem services, such as the long-term storage of carbon in biomass and soil under various management and climate scenarios.

Abstract:

Abstract. The phase of precipitation and its distribution at the surface can affect water resources and the regional water cycle of a region. A field project was held in March–April 2015 on the eastern slope of the Canadian Rockies to document precipitation characteristics and associated atmospheric conditions. During the project, 60 % of the particles documented were rimed in relatively warm and dry conditions. Rain–snow transitions also occurred aloft and at the surface in sub-saturated conditions. Ice-phase precipitation falling through a saturated atmospheric layer with temperatures > 0 ∘C will start melting. In contrast, if the melting layer is sub-saturated, the ice-phase precipitation undergoes sublimation, which increases the depth of the rain–snow transition. In this context, this study investigates the role of sublimation and riming in precipitation intensity and type reaching the surface in the Kananaskis Valley, Alberta, during March–April 2015. To address this, a set of numerical simulations of an event of mixed precipitation observed at the surface was conducted. This event on 31 March 2015 was documented with a set of devices at the main observation site (Kananaskis Emergency Services, KES), including a precipitation gauge, disdrometer, and micro rain radar. Sensitivity experiments were performed to assess the impacts of temperature changes from sublimation and the role of the production of graupel (riming) aloft in the surface precipitation evolution. A warmer environment associated with no temperature changes from sublimation leads to a peak in the intensity of graupel at the surface. When the formation of graupel is not considered, the maximum snowfall rate occurred at later times. Results suggest that unrimed snow reaching the surface is formed on the western flank and is advected eastward. In contrast, graupel would form aloft in the Kananaskis Valley. The cooling from sublimation and melting by rimed particles increases the vertical shear near KES. Overall, this study illustrated that the presence of graupel influenced the surface evolution of precipitation type in the valley due to the horizontal transport of precipitation particles.

Abstract:

This study aims to develop an activity-based science learning model with an inquiry learning approach for early childhood that can be used to increase the sense of curiosity and scientific thinking in children aged 5-6 years. This research was conducted with research and development / R & D research methods. Data was collected through interviews, observations, questionnaires, pre-test and post-test for children. Data analysis using paired t-test. The results showed that children were interested and enthusiastic in the learning process by using a science-based learning model with the inquiry approach, Sig. (2-tailed) showing results of 0.000, so the value of 0.000 <0.05 was different from before and after the use of learning models. The results showed that: children can understand the material given by the teacher, the child is more confident and has the initiative to find answers to the teacher's questions about science material, the child's curiosity increases to examine the information provided by the teacher, the child's understanding of work processes and procedures from science learning with the inquiry approach getting better. It was concluded that an activity-based science learning model with an inquiry approach for children aged 5-6 years used an activity model with an inquiry learning approach based on children's interests and children's needs so that children's curiosity would emerge and continue to be optimally stimulated.

Abstract:

Climate change induced sea-level rise (SLR) is on its increase globally. Regionally the lowlands of China, Vietnam, Bangladesh, and islands of the Malaysian, Indonesian and Philippine archipelagos are among the world’s most threatened regions. Sea-level rise has major impacts on the ecosystems and society. It threatens coastal populations, economic activities, and fragile ecosystems as mangroves, coastal salt-marches and wetlands. This paper provides a summary of the current state of knowledge of sea level-rise and its effects on both human and natural ecosystems. The focus is on coastal urban areas and low lying deltas in South-East Asia and Vietnam, as one of the most threatened areas in the world. About 3 mm per year reflects the growing consensus on the average SLR worldwide. The trend speeds up during recent decades. The figures are subject to local, temporal and methodological variation. In Vietnam the average values of 3.3 mm per year during the 1993-2014 period are above the worldwide average. Although a basic conceptual understanding exists that the increasing global frequency of the strongest tropical cyclones is related with the increasing temperature and SLR, this relationship is insufficiently understood. Moreover the precise, complex environmental, economic, social, and health impacts are currently unclear. SLR, storms and changing precipitation patterns increase flood risks, in particular in urban areas. Part of the current scientific debate is on how urban agglomeration can be made more resilient to flood risks. Where originally mainly technical interventions dominated this discussion, it becomes increasingly clear that proactive special planning, flood defense, flood risk mitigation, flood preparation, and flood recovery are important, but costly instruments. Next to the main focus on SLR and its effects on resilience, the paper reviews main SLR associated impacts: Floods and inundation, salinization, shoreline change, and effects on mangroves and wetlands. The hazards of SLR related floods increase fastest in urban areas. This is related with both the increasing surface major cities are expected to occupy during the decades to come and the increasing coastal population. In particular Asia and its megacities in the southern part of the continent are increasingly at risk. The discussion points to complexity, inter-disciplinarity, and the related uncertainty, as core characteristics.

Abstract:

Rapid urbanization rates impact significantly on the nature of Land Cover patterns of the environment, which has been evident in the depletion of vegetal reserves and in general modifying the human climatic systems (Henderson, et al., 2017; Kumar, Masago, Mishra, & Fukushi, 2018; Luo and Lau, 2017). This study explores remote sensing classification technique and other auxiliary data to determine LULCC for a period of 50 years (1967-2016). The LULCC types identified were quantitatively evaluated using the change detection approach from results of maximum likelihood classification algorithm in GIS. Accuracy assessment results were evaluated and found to be between 56 to 98 percent of the LULC classification. The change detection analysis revealed change in the LULC types in Minna from 1976 to 2016. Built-up area increases from 74.82ha in 1976 to 116.58ha in 2016. Farmlands increased from 2.23 ha to 46.45ha and bared surface increases from 120.00ha to 161.31ha between 1976 to 2016 resulting to decline in vegetation, water body, and wetlands. The Decade of rapid urbanization was found to coincide with the period of increased Public Private Partnership Agreement (PPPA). Increase in farmlands was due to the adoption of urban agriculture which has influence on food security and the environmental sustainability. The observed increase in built up areas, farmlands and bare surfaces has substantially led to reduction in vegetation and water bodies. The oscillatory nature of water bodies LULCC which was not particularly consistent with the rates of urbanization also suggests that beyond the urbanization process, other factors may influence the LULCC of water bodies in urban settlements.

The method used was descriptive qualitative with the subject of teachers in the Malang City area. Data was collected by using a survey distributed online through Google Forms. The results showed that the implementation pattern ofconstructivist theory in limited face-to-face learning (PTMT) was carried out through 5 (five) base of learning implementation, namely the application of problem-based learning, the application of project-based learning, the use of digital-based teaching materials and media, the application of psychosocial learning and contextuallearning. Teachers carried out limited face-to-face learning by applying constructivist theory massively and gradually, starting from planning, the process of learning activities, and learning evaluation. In addition to the use of media and 5M learning models in this study, the application of constructivist theory in PTMT learning aimed to help students become more active and teachers as moderators be more innovative. Learning process carried out at the elementary school level was only 50 percent attendance at the maximum. The implementation of student-centered learning showed 45% was very good, 50% was good, 2.5% was good, 2.5% was not good. The results showed that the inhibiting factor for student-centered implementation was the limited duration of time in learning. On the other hand, there were also restrictions on interactions carried out in the classroom so that teachers experienced a decline in exploring the learning process. Keywords: constructivism theory. limited face-to-face learning, elementary school. References: Adiyono, A. 2021.

Abstract:

AbstractTechnological advancements in the field of transportation are gradually enabling cooperative, connected and automated mobility (CCAM). The progress in information and communication technology (ICT) has provided mature solutions for infrastructure-to-vehicle (I2V) communication, which enables the deployment of Cooperative-ITS (C-ITS) services that can foster comfortable, safe, environmentally friendly, and more efficient traffic operations. This study focuses on the enhancement of speed advice comfort and safety in the proximity of signalized intersections, while ensuring energy and traffic efficiency. A detailed microscopic simulation model of an urban network in the city of Thessaloniki, Greece is used as test bed. The performance of dynamic eco-driving is evaluated for different penetration rates of the dynamic eco-driving technology and varying traffic conditions. The simulation analysis indicates that speed advice can be comfortable and safe without adversely impacting energy and traffic efficiency. However, efficient deployment of dynamic eco-driving depends on road design characteristics, activation distance of the service, traffic signal plans, and prevailing traffic conditions.

Abstract:

AbstractThis paper aims to determine the economic and technical feasibility of developing a thermally enhanced digester in the Andean area using solar collectors. Communities in the rural area of the Andes lack access to electricity and other basic services which impact negatively on their everyday life and exposes them to harmful and inefficient fuels. Several experiences with anaerobic digestion prove that this technology could be applied in the Andean area, although its performance is limited due to low temperatures. To overcome this constraint, an enhanced digester was modelled and simulated using TRNSYS Software. The system consisted of two solar collectors, a storage tank and a digester with a wrapped-around heat exchanger. The average digester temperature in the simulation was 30.7 °C. The enhanced temperature was used in a model to calculate the daily biogas production. The Net Present Value and Internal Rate of Return were calculated and confirm the economic viability of the project. The biogas production fully covers the requirements of the system for household cooking and lighting, making a significant social impact. This simulation indicates that it is technically possible to develop an enhanced digester in the Andean area that is economically viable as well.

Abstract:

Background: NTI Competence Center, in the direction “Technologies of Storage and Analysis of Big Data,” has significant background in the development of integral indexes: a) IQ Cities (to Ministry of Construction of the Russian Federation), b) National Index of digital development of the subjects of the Russian Federation, c) Index of readiness of industries for the introduction of artificial intelligence, d) Index of innovative development for leading domestic companies, including in the sector of air transportation and oil production. Objective: Today, innovative, scientific, and technical development is one of the key factors in maintaining the competitiveness of the railway industry in the transport services market. At the same time, innovative development is a complex and dynamically changing process, due to the high rates of development and implementation of new technologies on the level of commercial use in various tech companies. Therefore, it is advisable to use an assessment of the level of innovative development of a company in comparison with the market competitors. Today in the railway industry, there is a need to assess and constantly monitor the level of innovative development of companies. The relevance of building a single tool for assessing the level of innovative development of railway companies is due to the lack of unified and comprehensive methods for calculating such indexes in the industry and the necessary efficiency of innovative railway companies to increase their competitiveness in the transport services market. Methods: The main research methods used were bibliometric analysis, qualitative methods of information analysis and quantitative methods for the development of integral indexes (methods for standardizing indicators, methods for assigning specific weights, methods for aggregating indicators). The data for the assessment of the indicators as in 2019 were collected using available sources of information (including official reports and strategic planning documents of railway companies, scientific literature from the Scopus/Web of Science databases) and the opinions of independent industry experts. There are three groups of indicators used to form an integral assessment: - indicators for assessing the level of readiness of advanced innovative solutions and technologies (indicators are measured on a scale from 0 to 1 using the Technology Readiness Level scale, where 0 is no solution/ no supporting data; 0.5 is a solution at the development stage (TRL1-7), 0.75 is a solution at the approbation stage (TRL8), 1 is a solution at the production stage (TRL9). - binary indicators for assessing the presence or absence of the use of advanced innovative solutions and technologies (indicators are measured on a scale from 0 to 1, where 0 is no relevant functional (specific characteristic/ capability), 0.5 is possible existence with consideration of indirect factors, 1 - confirmed existence). - quantitative indicators for assessing the effectiveness and scope of innovation policy and the use of advanced innovative solutions and technologies (evaluated and ranked based on the minimum-maximum method). To aggregate these groups of indicators at the subindex level, there was calculated a subindex of the average value of the indicators. All the weights of the indicators included in one subindex are the same. Results: The scientific result of the research is the development of a unique method (structure of the indicators) for calculating the integral index of innovative development of railway companies based on the analysis of the best domestic and foreign practices and approaches to the formation of integral indexes. The method for calculating the index was successfully tested as a part of the assessment of the level of innovative development of the Russian Railways holding. Conclusion: The main result of this work is integral index that has prospects in international practice as a tool for strategic planning of the activities of railway companies to improve efficiency and optimize work processes, as well as a tool for assessing the level of dynamics of the innovative development of the industry and increasing its competitiveness in comparison with other modes of transport.

Abstract:

Abstract Background In diagnostic evaluation, it is necessary to assess the clinical impact of a new diagnostic as well as its diagnostic accuracy. The comparative interrupted time series design has been proposed as a quasi-experimental approach to evaluating interventions. We show how it can be used in the design of a study to evaluate a point-of-care diagnostic test for C-reactive protein in out-of-hours primary care services, to guide antibiotic prescribing among patients presenting with possible respiratory tract infection. This study consisted of a retrospective phase that used routinely collected monthly antibiotic prescribing data from different study sites, and a prospective phase in which antibiotic prescribing rates were monitored after the C-reactive protein diagnostic was introduced at some of the sites. Methods Of 8 study sites, 3 were assigned to receive the diagnostic and 5 were assigned as controls. We obtained retrospective monthly time series of respiratory tract targeted antibiotic prescriptions at each site. Separate ARIMA models at each site were used these to forecast monthly prescription counts that would be expected in the prospective phase, using simulation to obtain a set of 1-year predictions alongside their standard errors. We show how these forecasts can be combined to test for a change in prescription rates after introduction of the diagnostic and estimate power to detect this change. Results Fitted time series models at each site were stationary and showed second-order annual seasonality, with a clear December peak in prescriptions, although the timing and extent of the peak varied between sites and between years. Mean one-year predictions of antibiotic prescribing rates based on the retrospective time series analysis differed between sites assigned to receive the diagnostic and those assigned to control. Adjusting for the trend in the retrospective time series at each site removed these differences. Conclusions Quasi-experimental designs such as comparative interrupted time series can be used in diagnostic evaluation to estimate effect sizes before conducting a full randomised controlled trial or if a randomised trial is infeasible. In multi-site studies, existing retrospective data should be used to adjust for underlying differences between sites to make outcome data from different sites comparable, when possible.

Abstract:

The marine ecosystem provides the environment, resources, and services necessary for the development of every human society. In recent years, China's coastal zone has been polluted to varying degrees, which has seriously affected its development. The characteristics of marine environmental data include the variety of data types, the complexity of factors affecting the marine environment, and the unpredictability of marine pollution. Currently, there are few studies applying the clustering analysis algorithm to marine environmental monitoring. Then, carbon emissions (CEs) from coastal areas are predicted using marine environmental data. Therefore, this paper mainly studies the spatial and temporal accumulation characteristics of marine environmental data and uses the fuzzy c-means (FCM) algorithm to mine the data monitored by the marine environment. Meanwhile, it has been focused on the prediction of coastal CEs, and the grey model-back propagation (GM-BP) algorithm has been developed to predict CEs from coastal areas, which solves the problem that the traditional back propagation neural network (BPNN) cannot fully learn data features, which leads to a decline in accuracy. The experimental results showed that the FCM algorithm can divide the marine sample data into corresponding categories to distinguish polluted and unpolluted samples. The improved neural network model has a higher degree of non-linear fit and lower prediction error than a back propagation (BP) neural network. The main contribution of this paper is to first study the spatial and temporal accumulation characteristics of marine environmental data. The academic contribution of this study is to substitute the predictions of the three gray models (GMs) with the neural network structure simulation to finally obtain more accurate predictions. From a practical point of view, this study is helpful to a certain extent in alleviating the pressure of climate change due to increased CEs in global coastal zones. This study can also provide a new method of measuring environmental governance for marine environmental regulatory authorities.

Full text

Abstract:

Cover crops provide agro-ecological services like erosion control, improvement of soil quality, reduction of nitrate leaching and weed control. Before planting the subsequent cash crop, cover crops need to be terminated with herbicides, mechanically or with the help of frost (winterkill). Winterkill termination is expected to increase its relevance in the next years, especially for organic farming due to limitations in the use of herbicides and for conservation agriculture cropping systems. Termination by frost depends on complex interactions between genotype, development stage and weather conditions. To understand these interactions for management purposes, crop frost damage models, whose review is the purpose of this article, can be very useful. A literature search led to the collection of eight frost damage models, mainly dedicated to winter wheat. Three of these models are described in detail because they appear suited to adaptation to cover crops. Indeed, they explicitly simulate frost tolerance acquisition and loss as influenced by development stage using a crop frost tolerance temperature, whose rate of variation depends on the processes of hardening and dehardening. This tolerance temperature is compared daily with environmental temperature to calculate frost damage to the vegetative organs. The three models, when applied to winter wheat in Canada, Norway and France, have shown good agreement between measured and simulated crop frost tolerance temperature (when declared, the root mean squared error was 2.4°C). To compare the behaviour of these models, we applied them in two locations with different climatic conditions (temperate climate: Sant’Angelo Lodigiano, Italy, and continental climate: Saskaatoon, Canada) with respect to frost tolerance acquisition. This comparison revealed that the three models provide different simulated dates for the frost damage event in the continental site, while they are more similar in the temperate site. In conclusion, we have shown that the reviewed models are potentially suitable for simulating cover crop frost damage. Highlights - Frost termination is very important for cover crops and needs to be simulated with crop models. - Lacking a cover crop frost damage model, we review eight models simulating damage of cash crops, namely cereals. - Three of these models are also applicable to cover crops and are described in more detail. - The simulated crop frost tolerance temperature decreases and increases with hardening and dehardening, respectively. - This tolerance temperature is compared with environmental temperature to calculate frost damage to the crop.

Abstract:

The copyrighting of digital augmentations (our data-flesh), their privatization and ownership by others from a vast distance that is simultaneously instantly telematically surmountable started simply enough. It was the initially innocuous corporatization of language and semiotics that started the deeper ontological flip, which placed the posthuman bits and parts over the posthuman that thought that it was running things. The posthumans in question, myself included, didn't help things much when, for instance, we all clicked an unthinking or unconcerned "yes" to Facebook® or Gmail®'s "terms and conditions of use" policies that gives them the real ownership and final say over those data based augments of sociality, speech, and memory. Today there is growing popular concern (or at least acknowledgement) over the surveillance of these augmentations by government, especially after the Edward Snowden NSA leaks. The same holds true for the dataveillance of data-flesh (i.e. Gmail® or Facebook® accounts) by private corporations for reasons of profit and/or at the behest of governments for reasons of "national security." While drawing a picture of this (bodily) state, of the intrusion through language of brands into our being and their coterminous policing of intelligible and iterative body boundaries and extensions, I want to address the next step in copyrighted augmentation, one that is current practice in professional sport, and part of the bourgeoning "anti-aging" industry, with rewriting of cellular structure and hormonal levels, for a price, on the open market. What I want to problematize is the contradiction between the rhetorical moralizing against upgrading the analogue-flesh, especially with respect to celebrity sports stars like Lance Armstrong and Alex Rodriquez, all the while the "anti-aging" industry does the same without censor. Indeed, it does so within the context of the contradictory social messaging and norms that our data-flesh and electric augmentations receive to constantly upgrade. I pose the question of the contradiction between the messages given to our analogue-flesh and data-flesh in order to examine the specific site of commentary on professional sports stars and their practices, but also to point to the ethical gap that exists not just for (legal) performance enhancing drugs (PED), but also to show the link to privatized and copyrighted genomic testing, the dataveillance of this information, and subsequent augmentations that may be undertaken because of the results. Copyrighted Language and Semiotics as Gateway Drug The corporatization of language and semiotics came about with an intrusion of exclusively held signs from the capitalist economy into language. This makes sense if one want to make surplus value greater: stamp a name onto something, especially a base commodity like a food product, and build up the name of that stamp, however one will, so that that name has perceived value in and of itself, and then charge as much as one can for it. Such is the story of the lack of real correlation between the price of Starbucks Coffee® and coffee as a commodity, set by Starbucks® on the basis of the cultural worth of the symbols and signs associated with it, rather than by what they pay for the labor and production costs prior to its branding. But what happens to these legally protected stamps once they start acting as more than just a sign and referent to a subsection of a specific commodity or thing? Once the stamp has worth and a life that is socially determined? What happens when these stamps get verbed, adjectived, and nouned? Naomi Klein, in the book that the New York Times referred to as a "movement bible" for the anti-globalization forces of the late 1990s said "logos, by the force of ubiquity, have become the closest thing we have to an international language, recognized and understood in many more places than English" (xxxvi). But there is an inherent built-in tension of copyrighted language and semiotics that illustrates the coterminous problems with data- and analogue-flesh augments. "We have almost two centuries' worth of brand-name history under our collective belt, coalescing to create a sort of global pop-cultural Morse code. But there is just one catch: while we may all have the code implanted in our brains, we're not really allowed to use it" (Klein 176). Companies want their "brands to be the air you breathe in - but don't dare exhale" or otherwise try to engage in a two-way dialogue that alters the intended meaning (Klein 182). Private signs power first-world and BRIC capitalism, language, and bodies. I do not have a coffee in the morning; I have Starbucks®. I do not speak on a cellular phone; I speak iPhone®. I am not using my computer right now; I am writing MacBook Air®. I do not look something up, search it, or research it; I Google® it. Klein was writing before the everyday uptake of sophisticated miniaturized and mobile computing and communication devices. With the digitalization of our senses and electronic limbs this viral invasion of language became material, effecting both our data- and analogue-flesh. The trajectory? First we used it; then we wore it as culturally and socially demarcating clothing; and finally we no longer used copyrighted speech terms: it became an always-present augmentation, an adjective to the lexicon body of language, and thereby out of democratic semiotic control. Today Twitter® is our (140 character limited) medium of speech. Skype® is our sense of sight, the way we have "real" face-to-face communication. Yelp® has extended our sense of taste and smell through restaurant reviews. The iPhone® is our sense of hearing. And OkCupid® and/or Grindr® and other sites and apps have become the skin of our sexual organs (and the site where they first meet). Today, love at first sight happens through .jpeg extensions; our first sexual experience ranked on a scale of risk determined by the type of video feed file format used: was it "protected" enough to stop its "spread"? In this sense the corporatization of language and semiotics acted as the gateway drug to corporatized digital-flesh; from use of something that is external to us to an augmentation that is part of us and indeed may be in excess of us or any notion of a singular liberal subject.Replacement of Analogue-Flesh? Arguably, this could be viewed as the coming to be of the full replacement of the fleshy analogue body by what are, or started as digital augmentations. Is this what Marshall McLuhan meant when he spoke of the "electronic exteriorization of the central nervous system" through the growing complexity of our "electric extensions"? McLuhan's work that spoke of the "global village" enabled by new technologies is usually read as a euphoric celebration of the utopic possibilities of interconnectivity. What these misreadings overlook is the darker side of his thought, where the "cultural probe" picks up the warning signals of the change to come, so that a Christian inspired project, a cultural Noah’s Ark, can be created to save the past from the future to come (Coupland). Jean Baudrillard, Paul Virilio, and Guy Debord have analyzed this replacement of the real and the changes to the relations between people—one I am arguing is branded/restricted—by offering us the terms simulacrum (Baudrillard), substitution (Virilio), and spectacle (Debord). The commonality which links Baudrillard and Virilio, but not Debord, is that the former two do not explicitly situate their critique as being within the loss of the real that they then describe. Baudrillard expresses that he can have a 'cool detachment' from his subject (Forget Foucault/Forget Baudrillard), while Virilio's is a Catholic moralist's cry lamenting the disappearance of the heterogeneous experiential dimensions in transit along the various axes of space and time. What differentiates Debord is that he had no qualms positioning his own person and his text, The Society of the Spectacle (SotS), as within its own subject matter - a critique that is limited, and acknowledged as such, by the blindness of its own inescapable horizon.This Revolt Will Be Copyrighted Yet today the analogue - at the least - performs a revolt in or possibly in excess of the spectacle that seeks its containment. How and at what site is the revolt by the analogue-flesh most viewable? Ironically, in the actions of celebrity professional sports stars and the Celebrity Class in general. Today it revolts against copyrighted data-flesh with copyrighted analogue-flesh. This is even the case when the specific site of contestation is (at least the illusion of) immortality, where the runaway digital always felt it held the trump card. A regimen of Human Growth Hormone (HGH) and other PEDs purports to do the same thing, if not better, at the cellular level, than the endless youth paraded in the unaging photo employed by the Facebook or Grindr Bodies®. But with the everyday use and popularization of drugs and enhancement supplements like HGH and related PEDs there is something more fundamental at play than the economic juggernaut that is the Body Beautiful; more than fleshy jealousy of Photoshopped® electronic skins. This drug use represents the logical extension of the ethics that drive our tech-wired lives. We are told daily to upgrade: our sexual organs (OkCupid® or Grindr®) for a better, more accurate match; our memory (Google® services) for largeness and safe portability; and our hearing and sight (iPhone® or Skype®) for increase connectivity, engaging the "real" (that we have lost). These upgrades are controlled and copyrighted, but that which grows the economy is an especially favored moral act in an age of austerity. Why should it be surprising, then, that with the economic backing of key players of Google®—kingpin of the global for-profit dataveillance racket—that for $99.95 23andMe® will send one a home DNA test kit, which once returned will be analyzed for genetic issues, with a personalized web-interface, including "featured links." Analogue-flesh fights back with willing copyrighted dataveillance of its genetic code. The test and the personalized results allow for augmentations of the Angelina Jolie type: private testing for genetic markers, a double mastectomy provided by private healthcare, followed by copyrighted replacement flesh. This is where we find the biopolitics of data- and analogue-flesh, lead forth, in an ironic turn, by the Celebrity Class, whom depend for their income on the lives of their posthuman bodies. This is a complete reversal of the course Debord charts out for them: The celebrity, the spectacular representation of a living human being, embodies this banality by embodying the image of a possible role. Being a star means specializing in the seemingly lived; the star is the object of identification with the shallow seeming life that has to compensate for the fragmented productive specializations which are actually lived. (SotS) While the electronic global village was to have left the flesh-and-blood as waste, today there is resistance by the analogue from where we would least expect it - attempts to catch up and replant itself as ontologically prior to the digital through legal medical supplementation; to make the posthuman the posthuman. We find the Celebrity Class at the forefront of the resistance, of making our posthuman bodies as controlled augmentations of a posthuman. But there is a definite contradiction as well, specifically in the press coverage of professional sports. The axiomatic ethical and moral sentiment of our age to always upgrade data-flesh and analogue-flesh is contradicted in professional sports by the recent suspensions of Lance Armstrong and Alex Rodriguez and the political and pundit critical commentary on their actions. Nancy Reagan to the Curbside: An Argument for Lance Armstrong and Alex Rodriguez's "Just Say Yes to Drugs" Campaign Probably to the complete shock of most of my family, friends, students, and former lovers who may be reading this, I actually follow sports reporting with great detail and have done so for years. That I never speak of any sports in my everyday interactions, haven't played a team or individual sport since I could speak (and thereby use my voice to inform my parents that I was refusing to participate), and even decline amateur or minor league play, like throwing a ball of any kind at a family BBQ, leaves me to, like Judith Butler, "give an account of oneself." And this accounting for my sports addiction is not incidental or insignificant with respect either to how the posthuman present can move from a state of posthumanism to one of posthumanism, nor my specific interpellation into (and excess) in either of those worlds. Recognizing that I will not overcome my addiction without admitting my problem, this paper is thus a first-step public acknowledgement: I have been seeing "Dr. C" for a period of three years, and together, through weekly appointments, we have been working through this issue of mine. (Now for the sake of avoiding the cycle of lying that often accompanies addiction I should probably add that Dr. C is a chiropractor who I see for back and nerve damage issues, and the talk therapy portion, a safe space to deal with the sports addiction, was an organic outgrowth of the original therapy structure). My data-flesh that had me wired in and sitting all the time had done havoc to the analogue-flesh. My copyrighted augments were demanding that I do something to remedy a situation where I was unable to be sitting and wired in all the time. Part of the treatment involved the insertion of many acupuncture needles in various parts of my body, and then having an electric current run through them for a sustained period of time. Ironically, as it was the wired augmentations that demanded this, due to my immobility at this time - one doesn't move with acupuncture needles deep within the body - I was forced away from my devices and into unmediated conversation with Dr. C about sports, celebrity sports stars, and the recent (argued) infractions by Armstrong and Rodriguez. Now I say "argued" because in the first place are what A-Rod and Armstrong did, or are accused of doing, the use of PEDs, HGH, and all the rest (cf. Lupica; Thompson, and Vinton) really a crime? Are they on their way, or are there real threats of jail and criminal prosecution? And in the most important sense, and despite all the rhetoric, are they really going against prevailing social norms with respect to medical enhancement? No, no, and no. What is peculiar about the "witch-hunt" of A-Rod and Armstrong - their words - is that we are undertaking it in the first place, while high-end boutique medical clinics (and internet pharmacies) offer the same treatment for analogue-flesh. Fixes for the human in posthuman; ways of keeping the human up to speed; arguably the moral equivalent, if done so with free will, of upgrading the software for ones iOS device. If the critiques of Baudrillard and Virilio are right, we seem to find nothing wrong with crippling our physical bodies and social skills by living through computers and telematic technologies, and obsess over the next upgrade that will make us (more) faster and quicker (than the other or others), while we righteously deny the same process to the flesh for those who, in Debord's description, are the most complicit in the spectacle, to the supposedly most posthuman of us - those that have become pure spectacle (Debord), pure simulation (Baudrillard), a total substitution (Virilio). But it seems that celebrities, and sports celebrities in specific haven't gone along for the ride of never-ending play of their own signifiers at the expense of doing away with the real; they were not, in Debord's words, content with "specializing in the seemingly lived"; they wanted, conversely, to specialize in the most maximally lived flesh, right down to cellular regeneration towards genetic youth, which is the strongest claim in favor of taking HGH. It looks like they were prepared to, in the case of Armstrong, engage in the "most sophisticated, professionalized and successful doping program that sport has ever seen" in the name of the flesh (BBC). But a doping program that can, for the most part, be legally obtained as treatment, and in the same city as A-Rod plays in and is now suspended for his "crimes" to boot (NY Vitality). This total incongruence between what is desired, sought, and obtained legally by members of their socioeconomic class, and many classes below as well, and is a direct outgrowth of the moral and ethical axiomatic of the day is why A-Rod and Armstrong are so bemused, indignant, and angry, if not in a state of outright denial that they did anything that was wrong, even while they admit, explicitly, that yes, they did what they are accused of doing: taking the drugs. Perhaps another way is needed to look at the unprecedentedly "harsh" and "long" sentences of punishment handed out to A-Rod and Armstrong. The posthuman governing bodies of the sports of the society of the spectacle in question realize that their spectacle machines are being pushed back at. A real threat because it goes with the grain of where the rest of us, or those that can buy in at the moment, are going. And this is where the talk therapy for my sports addiction with Dr. C falls into the story. I realized that the electrified needles were telling me that I too should put the posthuman back in control of my damaged flesh; engage in a (medically copyrighted) piece of performance philosophy and offset some of the areas of possible risk that through restricted techne 23andMe® had (arguably) found. Dr. C and I were peeved with A-Rod and Armstrong not for what they did, but what they didn't tell us. We wanted better details than half-baked admissions of moral culpability. We wanted exact details on what they'd done to keep up to their digital-flesh. Their media bodies were cultural probes, full in view, while their flesh bodies, priceless lab rats, are hidden from view (and likely to remain so due to ongoing litigation). These were, after all, big money cover-ups of (likely) the peak of posthuman science, and the lab results are now hidden behind an army of sports federations lawyers, and agents (and A-Rod's own army since he still plays); posthuman progress covered up by posthuman rules, sages, and agents of manipulation. Massive posthuman economies of spectacle, simulation, or substitution of the real putting as much force as they can bare on resurgent posthuman flesh - a celebrity flesh those economies, posthuman economies, want to see as utterly passive like Debord, but whose actions are showing unexpected posthuman alignment with the flesh. Why are the centers of posthumanist power concerned? Because once one sees that A-Rod and Armstrong did it, once one sees that others are doing the same legally without a fuss being made, then one can see that one can do the same; make flesh-and-blood keep up, or regrow and become more organically youthful, while OkCupid® or Grindr® data-flesh gets stuck with the now lagging Photoshopped® touchups. Which just adds to my desire to get "pumped up"; add a little of A-Rod and Armstrong's concoction to my own routine; and one of a long list of reasons to throw Nancy Reagan under the bus: to "just say yes to drugs." A desire that is tempered by the recognition that the current limits of intelligibility and iteration of subjects, the work of defining the bodies that matter that is now set by copyrighted language and copyrighted electric extensions is only being challenged within this society of the spectacle by an act that may give a feeling of unease for cause. This is because it is copyrighted genetic testing and its dataveillance and manipulation through copyrighted medical technology - the various branded PEDs, HGH treatments, and their providers - that is the tool through which the flesh enacts this biopolitical "rebellion."References Baudrillard, Jean.

Abstract:

This article investigates the prosthesis of identity through the process of branding. It examines cross-cultural manifestations of this phenomena from sixth millennium BCE Syria to twelfth century Japan and Britain. From the Neolithic Era, humanity has sort to extend their identities using pictorial signs that were characteristically simple. Designed to be distinctive and instantly recognisable, the totemic symbols served to signal the origin of the bearer. Subsequently, the development of branding coincided with periods of increased in mobility both in respect to geography and social strata. This includes fifth millennium Mesopotamia, nineteenth century Britain, and America during the 1920s.There are fewer articles of greater influence on contemporary culture than A Theory of Human Motivation written by Abraham Maslow in 1943. Nearly seventy-five years later, his theories about the societal need for “belongingness” and “esteem” remain a mainstay of advertising campaigns (Maslow). Although the principles are used to sell a broad range of products from shampoo to breakfast cereal they are epitomised by apparel. This is with refence to garments and accessories bearing corporation logos. Whereas other purchased items, imbued with abstract products, are intended for personal consumption the public display of these symbols may be interpreted as a form of signalling. The intention of the wearers is to literally seek the fulfilment of the aforementioned social needs. This article investigates the use of brands as prosthesis.Coats and Crests: Identity Garnered on Garments in the Middle Ages and the Muromachi PeriodA logo, at its most basic, is a pictorial sign. In his essay, The Visual Language, Ernest Gombrich described the principle as reducing images to “distinctive features” (Gombrich 46). They represent a “simplification of code,” the meaning of which we are conditioned to recognise (Gombrich 46). Logos may also be interpreted as a manifestation of totemism. According to anthropologist Claude Levi-Strauss, the principle exists in all civilisations and reflects an effort to evoke the power of nature (71-127). Totemism is also a method of population distribution (Levi-Strauss 166).This principle, in a form garnered on garments, is manifested in Mon Kiri. The practice of cutting out family crests evolved into a form of corporate branding in Japan during the Meiji Period (1868-1912) (Christensen 14). During the Muromachi period (1336-1573) the crests provided an integral means of identification on the battlefield (Christensen 13). The adorning of crests on armour was also exercised in Europe during the twelfth century, when the faces of knights were similarly obscured by helmets (Family Crests of Japan 8). Both Mon Kiri and “Coat[s] of Arms” utilised totemic symbols (Family Crests of Japan 8; Elven 14; Christensen 13). The mon for the imperial family (figs. 1 & 2) during the Muromachi Period featured chrysanthemum and paulownia flowers (Goin’ Japaneque). “Coat[s] of Arms” in Britain featured a menagerie of animals including lions (fig. 3), horses and eagles (Elven).The prothesis of identity through garnering symbols on the battlefield provided “safety” through demonstrating “belongingness”. This constituted a conflation of two separate “needs” in the “hierarchy of prepotency” propositioned by Maslow. Fig. 1.

The Book of Family Crests: Comprising Nearly Every Family Bearing, Properly Blazoned and Explained, Accompanied by Upwards of Four Thousand Engravings. Henry Washbourne, 1847.The Pursuit of Prestige: Prosthetic Pedigree from the Late Georgian to the Victorian Eras In 1817, the seal engraver to Prince Regent, Alexander Deuchar, described the function of family crests in British Crests: Containing The Crest and Mottos of The Families of Great Britain and Ireland; Together with Those of The Principal Cities and Heraldic Terms as follows: The first approach to civilization is the distinction of ranks. So necessary is this to the welfare and existence of society, that, without it, anarchy and confusion must prevail… In an early stage, heraldic emblems were characteristic of the bearer… Certain ordinances were made, regulating the mode of bearing arms, and who were entitled to bear them. (i-v)The partitioning of social classes in Britain had deteriorated by the time this compendium was published, with displays of “conspicuous consumption” displacing “heraldic emblems” as a primary method of status signalling (Deuchar 2; Han et al. 18). A consumerism born of newfound affluence, and the desire to signify this wealth through luxury goods, was as integral to the Industrial Revolution as technological development. In Rebels against the Future, published in 1996, Kirkpatrick Sale described the phenomenon:A substantial part of the new population, though still a distinct minority, was made modestly affluent, in some places quite wealthy, by privatization of of the countryside and the industrialization of the cities, and by the sorts of commercial and other services that this called forth. The new money stimulated the consumer demand… that allowed a market economy of a scope not known before. (40)This also reflected improvements in the provision of “health, food [and] education” (Maslow; Snow 25-28). With their “physiological needs” accommodated, this ”substantial part” of the population were able to prioritised their “esteem needs” including the pursuit for prestige (Sale 40; Maslow).In Britain during the Middle Ages laws “specified in minute detail” what each class was permitted to wear (Han et al. 15). A groom, for example, was not able to wear clothing that exceeded two marks in value (Han et al. 15). In a distinct departure during the Industrial Era, it was common for the “middling and lower classes” to “ape” the “fashionable vices of their superiors” (Sale 41). Although mon-like labels that were “simplified so as to be conspicuous and instantly recognisable” emerged in Europe during the nineteenth century their application on garments remained discrete up until the early twentieth century (Christensen 13-14; Moore and Reid 24). During the 1920s, the French companies Hermes and Coco Chanel were amongst the clothing manufacturers to pioneer this principle (Chaney; Icon).During the 1860s, Lincolnshire-born Charles Frederick Worth affixed gold stamped labels to the insides of his garments (Polan et al. 9; Press). Operating from Paris, the innovation was consistent with the introduction of trademark laws in France in 1857 (Lopes et al.). He would become known as the “Father of Haute Couture”, creating dresses for royalty and celebrities including Empress Eugene from Constantinople, French actress Sarah Bernhardt and Australian Opera Singer Nellie Melba (Lopes et al.; Krick). The clothing labels proved and ineffective deterrent to counterfeit, and by the 1890s the House of Worth implemented other measures to authenticate their products (Press). The legitimisation of the origin of a product is, arguably, the primary function of branding. This principle is also applicable to subjects. The prothesis of brands, as totemic symbols, assisted consumers to relocate themselves within a new system of population distribution (Levi-Strauss 166). It was one born of commerce as opposed to heraldry.Selling of Self: Conferring Identity from the Neolithic to Modern ErasIn his 1817 compendium on family crests, Deuchar elaborated on heraldry by writing:Ignoble birth was considered as a stain almost indelible… Illustrious parentage, on the other hand, constituted the very basis of honour: it communicated peculiar rights and privileges, to which the meaner born man might not aspire. (v-vi)The Twinings Logo (fig. 4) has remained unchanged since the design was commissioned by the grandson of the company founder Richard Twining in 1787 (Twining). In addition to reflecting the heritage of the family-owned company, the brand indicated the origin of the tea. This became pertinent during the nineteenth century. Plantations began to operate from Assam to Ceylon (Jones 267-269). Amidst the rampant diversification of tea sources in the Victorian era, concerns about the “unhygienic practices” of Chinese producers were proliferated (Wengrow 11). Subsequently, the brand also offered consumers assurance in quality. Fig. 4. The Twinings Logo reproduced from "History of Twinings." Twinings. 24 July 2019 <https://www.twinings.co.uk/about-twinings/history-of-twinings>.The term ‘brand’, adapted from the Norse “brandr”, was introduced into the English language during the sixteenth century (Starcevic 179). At its most literal, it translates as to “burn down” (Starcevic 179). Using hot elements to singe markings onto animals been recorded as early as 2700 BCE in Egypt (Starcevic 182). However, archaeologists concur that the modern principle of branding predates this practice. The implementation of carved seals or stamps to make indelible impressions of handcrafted objects dates back to Prehistoric Mesopotamia (Starcevic 183; Wengrow 13). Similar traditions developed during the Bronze Age in both China and the Indus Valley (Starcevic 185). In all three civilisations branding facilitated both commerce and aspects of Totemism. In the sixth millennium BCE in “Prehistoric” Mesopotamia, referred to as the Halaf period, stone seals were carved to emulate organic form such as animal teeth (Wengrow 13-14). They were used to safeguard objects by “confer[ring] part of the bearer’s personality” (Wengrow 14). They were concurrently applied to secure the contents of vessels containing “exotic goods” used in transactions (Wengrow 15). Worn as amulets (figs. 5 & 6) the seals, and the symbols they produced, were a physical extension of their owners (Wengrow 14).Fig. 5.

Fig. 7. Recreation of stamp seal designs from Mesopotamia from the late fifth to fourth millennium BCE. Wengrow, David. "Prehistories of Commodity Branding." Current Anthropology 49. 1 (2008): 16.In the following millennia, the seals would increase exponentially in application and aesthetic complexity (fig. 7) to support the development of household cum cottage industries (Wengrow 15). In addition to handcrafts, sealed vessels would transport consumables such as wine, aromatic oils and animal fats (Wengrow 18). The illustrations on the seals included depictions of rituals undertaken by human figures and/or allegories using animals. It can be ascertained that the transition in the Victorian Era from heraldry to commerce, from family to corporation, had precedence. By extension, consumers were able to participate in this process of value attribution using brands as signifiers. The principle remained prevalent during the modern and post-modern eras and can be respectively interpreted using structuralist and post-structuralist theory.Totemism to Simulacrum: The Evolution of Advertising from the Modern to Post-Modern Eras In 2011, Lisa Chaney wrote of the inception of the Coco Chanel logo (fig. 8) in her biography Chanel: An Intimate Life: A crucial element in the signature design of the Chanel No.5 bottle is the small black ‘C’ within a black circle set as the seal at the neck. On the top of the lid are two more ‘C’s, intertwined back to back… from at least 1924, the No5 bottles sported the unmistakable logo… these two ‘C’s referred to Gabrielle, – in other words Coco Chanel herself, and would become the logo for the House of Chanel. Chaney continued by describing Chanel’s fascination of totemic symbols as expressed through her use of tarot cards. She also “surrounded herself with objects ripe with meaning” such as representations of wheat and lions in reference prosperity and to her zodiac symbol ‘Leo’ respectively. Fig. 8. No5 Chanel Perfume, released in 1924, featured a seal-like logo attached to the bottle neck. “No5.” Chanel. 25 July 2019 <https://www.chanel.com/us/fragrance/p/120450/n5-parfum-grand-extrait/>.Fig. 9. This illustration of the bottle by Georges Goursat was published in a women’s magazine circa 1920s. “1921 Chanel No5.” Inside Chanel. 26 July 2019 <http://inside.chanel.com/en/timeline/1921_no5>; “La 4éme Fête de l’Histoire Samedi 16 et dimache 17 juin.” Ville de Perigueux. Musée d’art et d’archéologie du Périgord. 28 Mar. 2018. 26 July 2019 <https://www.perigueux-maap.fr/category/archives/page/5/>. This product was considered the “financial basis” of the Chanel “empire” which emerged during the second and third decades of the twentieth century (Tikkanen). Chanel is credited for revolutionising Haute Couture by introducing chic modern designs that emphasised “simplicity and comfort.” This was as opposed to the corseted highly embellished fashion that characterised the Victorian Era (Tikkanen). The lavish designs released by the House of Worth were, in and of themselves, “conspicuous” displays of “consumption” (Veblen 17). In contrast, the prestige and status associated with the “poor girl” look introduced by Chanel was invested in the story of the designer (Tikkanen). A primary example is her marinière or sailor’s blouse with a Breton stripe that epitomised her ascension from café singer to couturier (Tikkanen; Burstein 8). This signifier might have gone unobserved by less discerning consumers of fashion if it were not for branding. Not unlike the Prehistoric Mesopotamians, this iteration of branding is a process which “confer[s]” the “personality” of the designer into the garment (Wengrow 13 -14). The wearer of the garment is, in turn, is imbued by extension. Advertisers in the post-structuralist era embraced Levi-Strauss’s structuralist anthropological theories (Williamson 50). This is with particular reference to “bricolage” or the “preconditioning” of totemic symbols (Williamson 173; Pool 50). Subsequently, advertising creatives cum “bricoleur” employed his principles to imbue the brands with symbolic power. This symbolic capital was, arguably, transferable to the product and, ultimately, to its consumer (Williamson 173).Post-structuralist and semiotician Jean Baudrillard “exhaustively” critiqued brands and the advertising, or simulacrum, that embellished them between the late 1960s and early 1980s (Wengrow 10-11). In Simulacra and Simulation he wrote,it is the reflection of a profound reality; it masks and denatures a profound reality; it masks the absence of a profound reality; it has no relation to any reality whatsoever: it is its own pure simulacrum. (6)The symbolic power of the Chanel brand resonates in the ‘profound reality’ of her story. It is efficiently ‘denatured’ through becoming simplified, conspicuous and instantly recognisable. It is, as a logo, physically juxtaposed as simulacra onto apparel. This simulacrum, in turn, effects the ‘profound reality’ of the consumer. In 1899, economist Thorstein Veblen wrote in The Theory of the Leisure Class:Conspicuous consumption of valuable goods it the means of reputability to the gentleman of leisure… costly entertainments, such as potlatch or the ball, are peculiarly adapted to serve this end… he consumes vicariously for his host at the same time that he is witness to the consumption… he is also made to witness his host’s facility in etiquette. (47)Therefore, according to Veblen, it was the witnessing of “wasteful” consumption that “confers status” as opposed the primary conspicuous act (Han et al. 18). Despite television being in its experimental infancy advertising was at “the height of its powers” during the 1920s (Clark et al. 18; Hill 30). Post-World War I consumers, in America, experienced an unaccustomed level of prosperity and were unsuspecting of the motives of the newly formed advertising agencies (Clark et al. 18). Subsequently, the ‘witnessing’ of consumption could be constructed across a plethora of media from the newly emerged commercial radio to billboards (Hill viii–25). The resulting ‘status’ was ‘conferred’ onto brand logos. Women’s magazines, with a legacy dating back to 1828, were a primary locus (Hill 10).Belonging in a Post-Structuralist WorldIt is significant to note that, in a post-structuralist world, consumers do not exclusively seek upward mobility in their selection of brands. The establishment of counter-culture icon Levi-Strauss and Co. was concurrent to the emergence of both The House of Worth and Coco Chanel. The Bavarian-born Levi Strauss commenced selling apparel in San Francisco in 1853 (Levi’s). Two decades later, in partnership with Nevada born tailor Jacob Davis, he patented the “riveted-for-strength” workwear using blue denim (Levi’s). Although the ontology of ‘jeans’ is contested, references to “Jene Fustyan” date back the sixteenth century (Snyder 139). It involved the combining cotton, wool and linen to create “vestments” for Geonese sailors (Snyder 138). The Two Horse Logo (fig. 10), depicting them unable to pull apart a pair of jeans to symbolise strength, has been in continuous use by Levi Strauss & Co. company since its design in 1886 (Levi’s). Fig. 10. The Two Horse Logo by Levi Strauss & Co. has been in continuous use since 1886. Staff Unzipped. "Two Horses. One Message." Heritage. Levi Strauss & Co. 1 July 2011. 25 July 2019 <https://www.levistrauss.com/2011/07/01/two-horses-many-versions-one-message/>.The “rugged wear” would become the favoured apparel amongst miners at American Gold Rush (Muthu 6). Subsequently, between the 1930s – 1960s Hollywood films cultivated jeans as a symbol of “defiance” from Stage Coach staring John Wayne in 1939 to Rebel without A Cause staring James Dean in 1955 (Muthu 6; Edgar). Consequently, during the 1960s college students protesting in America (fig. 11) against the draft chose the attire to symbolise their solidarity with the working class (Hedarty). Notwithstanding a 1990s fashion revision of denim into a diversity of garments ranging from jackets to skirts, jeans have remained a wardrobe mainstay for the past half century (Hedarty; Muthu 10). Fig. 11. Although the brand label is not visible, jeans as initially introduced to the American Goldfields in the nineteenth century by Levi Strauss & Co. were cultivated as a symbol of defiance from the 1930s – 1960s. It documents an anti-war protest that occurred at the Pentagon in 1967. Cox, Savannah. "The Anti-Vietnam War Movement." ATI. 14 Dec. 2016. 16 July 2019 <https://allthatsinteresting.com/vietnam-war-protests#7>.In 2003, the journal Science published an article “Does Rejection Hurt? An Fmri Study of Social Exclusion” (Eisenberger et al.). The cross-institutional study demonstrated that the neurological reaction to rejection is indistinguishable to physical pain. Whereas during the 1940s Maslow classified the desire for “belonging” as secondary to “physiological needs,” early twenty-first century psychologists would suggest “[social] acceptance is a mechanism for survival” (Weir 50). In Simulacra and Simulation, Jean Baudrillard wrote: Today abstraction is no longer that of the map, the double, the mirror or the concept. Simulation is no longer that of a territory, a referential being or a substance. It is the generation by models of a real without origin or reality: a hyperreal… (1)In the intervening thirty-eight years since this document was published the artifice of our interactions has increased exponentially. In order to locate ‘belongness’ in this hyperreality, the identities of the seekers require a level of encoding. Brands, as signifiers, provide a vehicle.Whereas in Prehistoric Mesopotamia carved seals, worn as amulets, were used to extend the identity of a person, in post-digital China WeChat QR codes (fig. 12), stored in mobile phones, are used to facilitate transactions from exchanging contact details to commerce. Like other totems, they provide access to information such as locations, preferences, beliefs, marital status and financial circumstances. These individualised brands are the most recent incarnation of a technology that has developed over the past eight thousand years. The intermediary iteration, emblems affixed to garments, has remained prevalent since the twelfth century. Their continued salience is due to their visibility and, subsequent, accessibility as signifiers. Fig. 12. It may be posited that Wechat QR codes are a form individualised branding. Like other totems, they store information pertaining to the owner’s location, beliefs, preferences, marital status and financial circumstances. “Join Wechat groups using QR code on 2019.” Techwebsites. 26 July 2019 <https://techwebsites.net/join-wechat-group-qr-code/>.Fig. 13. Brands function effectively as signifiers is due to the international distribution of multinational corporations. This is the shopfront of Chanel in Dubai, which offers customers apparel bearing consistent insignia as the Parisian outlet at on Rue Cambon. Customers of Chanel can signify to each other with the confidence that their products will be recognised. “Chanel.” The Dubai Mall. 26 July 2019 <https://thedubaimall.com/en/shop/chanel>.Navigating a post-structuralist world of increasing mobility necessitates a rudimental understanding of these symbols. Whereas in the nineteenth century status was conveyed through consumption and witnessing consumption, from the twentieth century onwards the garnering of brands made this transaction immediate (Veblen 47; Han et al. 18). The bricolage of the brands is constructed by bricoleurs working in any number of contemporary creative fields such as advertising, filmmaking or song writing. They provide a system by which individuals can convey and recognise identities at prima facie. They enable the prosthesis of identity.ReferencesBaudrillard, Jean. Simulacra and Simulation. Trans.

Abstract:

Introduction Figure 1 The counter-Terrorism advertising campaign of London’s Metropolitan Police commodifies some everyday items such as mobile phones, computers, passports and credit cards as having the potential to sustain terrorist activities. The process of ascribing cultural values and symbolic meanings to some everyday technical gadgets objectifies and situates Terrorism into the everyday life. The police, in urging people to look out for ‘the unusual’ in their normal day-to-day lives, juxtapose the everyday with the unusual, where day-to-day consumption, routines and flows of human activity can seemingly house insidious and atavistic elements. This again is reiterated in the Met police press release: Terrorists live within our communities making their plans whilst doing everything they can to blend in, and trying not to raise suspicions about their activities. (MPA Website) The commodification of Terrorism through uncommon and everyday objects situates Terrorism as a phenomenon which occupies a liminal space within the everyday. It resides, breathes and co-exists within the taken-for-granted routines and objects of ‘the everyday’ where it has the potential to explode and disrupt without warning. Since 9/11 and the 7/7 bombings Terrorism has been narrated through the disruption of mobility, whether in mid-air or in the deep recesses of the Underground. The resonant thread of disruption to human mobility evokes a powerful meta-narrative where acts of Terrorism can halt human agency amidst the backdrop of the metropolis, which is often a metaphor for speed and accelerated activities. If globalisation and the interconnected nature of the world are understood through discourses of risk, Terrorism bears the same footprint in urban spaces of modernity, narrating the vulnerability of the human condition in an inter-linked world where ideological struggles and resistance are manifested through inexplicable violence and destruction of lives, where the everyday is suspended to embrace the unexpected. As a consequence ambient fear “saturates the social spaces of everyday life” (Hubbard 2). The commodification of Terrorism through everyday items of consumption inevitably creates an intertextuality with real and media events, which constantly corrode the security of the metropolis. Paddy Scannell alludes to a doubling of place in our mediated world where “public events now occur simultaneously in two different places; the place of the event itself and that in which it is watched and heard. The media then vacillates between the two sites and creates experiences of simultaneity, liveness and immediacy” (qtd. in Moores 22). The doubling of place through media constructs a pervasive environment of risk and fear. Mark Danner (qtd. in Bauman 106) points out that the most powerful weapon of the 9/11 terrorists was that innocuous and “most American of technological creations: the television set” which provided a global platform to constantly replay and remember the dreadful scenes of the day, enabling the terrorist to appear invincible and to narrate fear as ubiquitous and omnipresent. Philip Abrams argues that ‘big events’ (such as 9/11 and 7/7) do make a difference in the social world for such events function as a transformative device between the past and future, forcing society to alter or transform its perspectives. David Altheide points out that since September 11 and the ensuing war on terror, a new discourse of Terrorism has emerged as a way of expressing how the world has changed and defining a state of constant alert through a media logic and format that shapes the nature of discourse itself. Consequently, the intensity and centralisation of surveillance in Western countries increased dramatically, placing the emphasis on expanding the forms of the already existing range of surveillance processes and practices that circumscribe and help shape our social existence (Lyon, Terrorism 2). Normalisation of Surveillance The role of technologies, particularly information and communication technologies (ICTs), and other infrastructures to unevenly distribute access to the goods and services necessary for modern life, while facilitating data collection on and control of the public, are significant characteristics of modernity (Reiman; Graham and Marvin; Monahan). The embedding of technological surveillance into spaces and infrastructures not only augment social control but also redefine data as a form of capital which can be shared between public and private sectors (Gandy, Data Mining; O’Harrow; Monahan). The scale, complexity and limitations of omnipresent and omnipotent surveillance, nevertheless, offer room for both subversion as well as new forms of domination and oppression (Marx). In surveillance studies, Foucault’s analysis is often heavily employed to explain lines of continuity and change between earlier forms of surveillance and data assemblage and contemporary forms in the shape of closed-circuit television (CCTV) and other surveillance modes (Dee). It establishes the need to discern patterns of power and normalisation and the subliminal or obvious cultural codes and categories that emerge through these arrangements (Fopp; Lyon, Electronic; Norris and Armstrong). In their study of CCTV surveillance, Norris and Armstrong (cf. in Dee) point out that when added to the daily minutiae of surveillance, CCTV cameras in public spaces, along with other camera surveillance in work places, capture human beings on a database constantly. The normalisation of surveillance, particularly with reference to CCTV, the popularisation of surveillance through television formats such as ‘Big Brother’ (Dee), and the expansion of online platforms to publish private images, has created a contradictory, complex and contested nature of spatial and power relationships in society. The UK, for example, has the most developed system of both urban and public space cameras in the world and this growth of camera surveillance and, as Lyon (Surveillance) points out, this has been achieved with very little, if any, public debate as to their benefits or otherwise. There may now be as many as 4.2 million CCTV cameras in Britain (cf. Lyon, Surveillance). That is one for every fourteen people and a person can be captured on over 300 cameras every day. An estimated £500m of public money has been invested in CCTV infrastructure over the last decade but, according to a Home Office study, CCTV schemes that have been assessed had little overall effect on crime levels (Wood and Ball). In spatial terms, these statistics reiterate Foucault’s emphasis on the power economy of the unseen gaze. Michel Foucault in analysing the links between power, information and surveillance inspired by Bentham’s idea of the Panopticon, indicated that it is possible to sanction or reward an individual through the act of surveillance without their knowledge (155). It is this unseen and unknown gaze of surveillance that is fundamental to the exercise of power. The design and arrangement of buildings can be engineered so that the “surveillance is permanent in its effects, even if it is discontinuous in its action” (Foucault 201). Lyon (Terrorism), in tracing the trajectory of surveillance studies, points out that much of surveillance literature has focused on understanding it as a centralised bureaucratic relationship between the powerful and the governed. Invisible forms of surveillance have also been viewed as a class weapon in some societies. With the advancements in and proliferation of surveillance technologies as well as convergence with other technologies, Lyon argues that it is no longer feasible to view surveillance as a linear or centralised process. In our contemporary globalised world, there is a need to reconcile the dialectical strands that mediate surveillance as a process. In acknowledging this, Giles Deleuze and Felix Guattari have constructed surveillance as a rhizome that defies linearity to appropriate a more convoluted and malleable form where the coding of bodies and data can be enmeshed to produce intricate power relationships and hierarchies within societies. Latour draws on the notion of assemblage by propounding that data is amalgamated from scattered centres of calculation where these can range from state and commercial institutions to scientific laboratories which scrutinise data to conceive governance and control strategies. Both the Latourian and Deleuzian ideas of surveillance highlight the disparate arrays of people, technologies and organisations that become connected to make “surveillance assemblages” in contrast to the static, unidirectional Panopticon metaphor (Ball, “Organization” 93). In a similar vein, Gandy (Panoptic) infers that it is misleading to assume that surveillance in practice is as complete and totalising as the Panoptic ideal type would have us believe. Co-optation of Millions The Metropolitan Police’s counter-Terrorism strategy seeks to co-opt millions where the corporeal body can complement the landscape of technological surveillance that already co-exists within modernity. In its press release, the role of civilian bodies in ensuring security of the city is stressed; Keeping Londoners safe from Terrorism is not a job solely for governments, security services or police. If we are to make London the safest major city in the world, we must mobilise against Terrorism not only the resources of the state, but also the active support of the millions of people who live and work in the capita. (MPA Website). Surveillance is increasingly simulated through the millions of corporeal entities where seeing in advance is the goal even before technology records and codes these images (William). Bodies understand and code risk and images through the cultural narratives which circulate in society. Compared to CCTV technology images, which require cultural and political interpretations and interventions, bodies as surveillance organisms implicitly code other bodies and activities. The travel bag in the Metropolitan Police poster reinforces the images of the 7/7 bombers and the renewed attempts to bomb the London Underground on the 21st of July. It reiterates the CCTV footage revealing images of the bombers wearing rucksacks. The image of the rucksack both embodies the everyday as well as the potential for evil in everyday objects. It also inevitably reproduces the cultural biases and prejudices where the rucksack is subliminally associated with a specific type of body. The rucksack in these terms is a laden image which symbolically captures the context and culture of risk discourses in society. The co-optation of the population as a surveillance entity also recasts new forms of social responsibility within the democratic polity, where privacy is increasingly mediated by the greater need to monitor, trace and record the activities of one another. Nikolas Rose, in discussing the increasing ‘responsibilisation’ of individuals in modern societies, describes the process in which the individual accepts responsibility for personal actions across a wide range of fields of social and economic activity as in the choice of diet, savings and pension arrangements, health care decisions and choices, home security measures and personal investment choices (qtd. in Dee). While surveillance in individualistic terms is often viewed as a threat to privacy, Rose argues that the state of ‘advanced liberalism’ within modernity and post-modernity requires considerable degrees of self-governance, regulation and surveillance whereby the individual is constructed both as a ‘new citizen’ and a key site of self management. By co-opting and recasting the role of the citizen in the age of Terrorism, the citizen to a degree accepts responsibility for both surveillance and security. In our sociological imagination the body is constructed both as lived as well as a social object. Erving Goffman uses the word ‘umwelt’ to stress that human embodiment is central to the constitution of the social world. Goffman defines ‘umwelt’ as “the region around an individual from which signs of alarm can come” and employs it to capture how people as social actors perceive and manage their settings when interacting in public places (252). Goffman’s ‘umwelt’ can be traced to Immanuel Kant’s idea that it is the a priori categories of space and time that make it possible for a subject to perceive a world (Umiker-Sebeok; qtd. in Ball, “Organization”). Anthony Giddens adapted the term Umwelt to refer to “a phenomenal world with which the individual is routinely ‘in touch’ in respect of potential dangers and alarms which then formed a core of (accomplished) normalcy with which individuals and groups surround themselves” (244). Benjamin Smith, in considering the body as an integral component of the link between our consciousness and our material world, observes that the body is continuously inscribed by culture. These inscriptions, he argues, encompass a wide range of cultural practices and will imply knowledge of a variety of social constructs. The inscribing of the body will produce cultural meanings as well as create forms of subjectivity while locating and situating the body within a cultural matrix (Smith). Drawing on Derrida’s work, Pugliese employs the term ‘Somatechnics’ to conceptualise the body as a culturally intelligible construct and to address the techniques in and through which the body is formed and transformed (qtd. in Osuri). These techniques can encompass signification systems such as race and gender and equally technologies which mediate our sense of reality. These technologies of thinking, seeing, hearing, signifying, visualising and positioning produce the very conditions for the cultural intelligibility of the body (Osuri). The body is then continuously inscribed and interpreted through mediated signifying systems. Similarly, Hayles, while not intending to impose a Cartesian dichotomy between the physical body and its cognitive presence, contends that the use and interactions with technology incorporate the body as a material entity but it also equally inscribes it by marking, recording and tracing its actions in various terrains. According to Gayatri Spivak (qtd. in Ball, “Organization”) new habits and experiences are embedded into the corporeal entity which then mediates its reactions and responses to the social world. This means one’s body is not completely one’s own and the presence of ideological forces or influences then inscribe the body with meanings, codes and cultural values. In our modern condition, the body and data are intimately and intricately bound. Outside the home, it is difficult for the body to avoid entering into relationships that produce electronic personal data (Stalder). According to Felix Stalder our physical bodies are shadowed by a ‘data body’ which follows the physical body of the consuming citizen and sometimes precedes it by constructing the individual through data (12). Before we arrive somewhere, we have already been measured and classified. Thus, upon arrival, the citizen will be treated according to the criteria ‘connected with the profile that represents us’ (Gandy, Panoptic; William). Following September 11, Lyon (Terrorism) reveals that surveillance data from a myriad of sources, such as supermarkets, motels, traffic control points, credit card transactions records and so on, was used to trace the activities of terrorists in the days and hours before their attacks, confirming that the body leaves data traces and trails. Surveillance works by abstracting bodies from places and splitting them into flows to be reassembled as virtual data-doubles, and in the process can replicate hierarchies and centralise power (Lyon, Terrorism). Mike Dee points out that the nature of surveillance taking place in modern societies is complex and far-reaching and in many ways insidious as surveillance needs to be situated within the broadest context of everyday human acts whether it is shopping with loyalty cards or paying utility bills. Physical vulnerability of the body becomes more complex in the time-space distanciated surveillance systems to which the body has become increasingly exposed. As such, each transaction – whether it be a phone call, credit card transaction, or Internet search – leaves a ‘data trail’ linkable to an individual person or place. Haggerty and Ericson, drawing from Deleuze and Guattari’s concept of the assemblage, describe the convergence and spread of data-gathering systems between different social domains and multiple levels (qtd. in Hier). They argue that the target of the generic ‘surveillance assemblage’ is the human body, which is broken into a series of data flows on which surveillance process is based. The thrust of the focus is the data individuals can yield and the categories to which they can contribute. These are then reapplied to the body. In this sense, surveillance is rhizomatic for it is diverse and connected to an underlying, invisible infrastructure which concerns interconnected technologies in multiple contexts (Ball, “Elements”). The co-opted body in the schema of counter-Terrorism enters a power arrangement where it constitutes both the unseen gaze as well as the data that will be implicated and captured in this arrangement. It is capable of producing surveillance data for those in power while creating new data through its transactions and movements in its everyday life. The body is unequivocally constructed through this data and is also entrapped by it in terms of representation and categorisation. The corporeal body is therefore part of the machinery of surveillance while being vulnerable to its discriminatory powers of categorisation and victimisation. As Hannah Arendt (qtd. in Bauman 91) had warned, “we terrestrial creatures bidding for cosmic significance will shortly be unable to comprehend and articulate the things we are capable of doing” Arendt’s caution conveys the complexity, vulnerability as well as the complicity of the human condition in the surveillance society. Equally it exemplifies how the corporeal body can be co-opted as a surveillance entity sustaining a new ‘banality’ (Arendt) in the machinery of surveillance. Social Consequences of Surveillance Lyon (Terrorism) observed that the events of 9/11 and 7/7 in the UK have inevitably become a prism through which aspects of social structure and processes may be viewed. This prism helps to illuminate the already existing vast range of surveillance practices and processes that touch everyday life in so-called information societies. As Lyon (Terrorism) points out surveillance is always ambiguous and can encompass genuine benefits and plausible rationales as well as palpable disadvantages. There are elements of representation to consider in terms of how surveillance technologies can re-present data that are collected at source or gathered from another technological medium, and these representations bring different meanings and enable different interpretations of life and surveillance (Ball, “Elements”). As such surveillance needs to be viewed in a number of ways: practice, knowledge and protection from threat. As data can be manipulated and interpreted according to cultural values and norms it reflects the inevitability of power relations to forge its identity in a surveillance society. In this sense, Ball (“Elements”) concludes surveillance practices capture and create different versions of life as lived by surveilled subjects. She refers to actors within the surveilled domain as ‘intermediaries’, where meaning is inscribed, where technologies re-present information, where power/resistance operates, and where networks are bound together to sometimes distort as well as reiterate patterns of hegemony (“Elements” 93). While surveillance is often connected with technology, it does not however determine nor decide how we code or employ our data. New technologies rarely enter passive environments of total inequality for they become enmeshed in complex pre-existing power and value systems (Marx). With surveillance there is an emphasis on the classificatory powers in our contemporary world “as persons and groups are often risk-profiled in the commercial sphere which rates their social contributions and sorts them into systems” (Lyon, Terrorism 2). Lyon (Terrorism) contends that the surveillance society is one that is organised and structured using surveillance-based techniques recorded by technologies, on behalf of the organisations and governments that structure our society. This information is then sorted, sifted and categorised and used as a basis for decisions which affect our life chances (Wood and Ball). The emergence of pervasive, automated and discriminatory mechanisms for risk profiling and social categorising constitute a significant mechanism for reproducing and reinforcing social, economic and cultural divisions in information societies. Such automated categorisation, Lyon (Terrorism) warns, has consequences for everyone especially in face of the new anti-terror measures enacted after September 11. In tandem with this, Bauman points out that a few suicidal murderers on the loose will be quite enough to recycle thousands of innocents into the “usual suspects”. In no time, a few iniquitous individual choices will be reprocessed into the attributes of a “category”; a category easily recognisable by, for instance, a suspiciously dark skin or a suspiciously bulky rucksack* *the kind of object which CCTV cameras are designed to note and passers-by are told to be vigilant about. And passers-by are keen to oblige. Since the terrorist atrocities on the London Underground, the volume of incidents classified as “racist attacks” rose sharply around the country. (122; emphasis added) Bauman, drawing on Lyon, asserts that the understandable desire for security combined with the pressure to adopt different kind of systems “will create a culture of control that will colonise more areas of life with or without the consent of the citizen” (123). This means that the inhabitants of the urban space whether a citizen, worker or consumer who has no terrorist ambitions whatsoever will discover that their opportunities are more circumscribed by the subject positions or categories which are imposed on them. Bauman cautions that for some these categories may be extremely prejudicial, restricting them from consumer choices because of credit ratings, or more insidiously, relegating them to second-class status because of their colour or ethnic background (124). Joseph Pugliese, in linking visual regimes of racial profiling and the shooting of Jean Charles de Menezes in the aftermath of 7/7 bombings in London, suggests that the discursive relations of power and visuality are inextricably bound. Pugliese argues that racial profiling creates a regime of visuality which fundamentally inscribes our physiology of perceptions with stereotypical images. He applies this analogy to Menzes running down the platform in which the retina transforms him into the “hallucinogenic figure of an Asian Terrorist” (Pugliese 8). With globalisation and the proliferation of ICTs, borders and boundaries are no longer sacrosanct and as such risks are managed by enacting ‘smart borders’ through new technologies, with huge databases behind the scenes processing information about individuals and their journeys through the profiling of body parts with, for example, iris scans (Wood and Ball 31). Such body profiling technologies are used to create watch lists of dangerous passengers or identity groups who might be of greater ‘risk’. The body in a surveillance society can be dissected into parts and profiled and coded through technology. These disparate codings of body parts can be assembled (or selectively omitted) to construct and represent whole bodies in our information society to ascertain risk. The selection and circulation of knowledge will also determine who gets slotted into the various categories that a surveillance society creates. Conclusion When the corporeal body is subsumed into a web of surveillance it often raises questions about the deterministic nature of technology. The question is a long-standing one in our modern consciousness. We are apprehensive about according technology too much power and yet it is implicated in the contemporary power relationships where it is suspended amidst human motive, agency and anxiety. The emergence of surveillance societies, the co-optation of bodies in surveillance schemas, as well as the construction of the body through data in everyday transactions, conveys both the vulnerabilities of the human condition as well as its complicity in maintaining the power arrangements in society. Bauman, in citing Jacques Ellul and Hannah Arendt, points out that we suffer a ‘moral lag’ in so far as technology and society are concerned, for often we ruminate on the consequences of our actions and motives only as afterthoughts without realising at this point of existence that the “actions we take are most commonly prompted by the resources (including technology) at our disposal” (91).
