Full textAbstract:
This article examines the telephone’s entangled history within contemporary infrastructural systems of ‘big data’, identity and, ultimately, surveillance. It explores the use of telephone numbers, keypads and wires to offer new perspective on the imbrication of telephonic information, interface and infrastructure within contemporary surveillance regimes. The article explores telephone exchanges as arbiters of cultural identities, keypads as the foundation of digital transactions and wireline networks as enacting the transformation of citizens and consumers into digital subjects ripe for commodification and surveillance. Ultimately, this article argues that telephone history – specifically the histories of telephone numbers and keypads as well as infrastructure and policy in the United States – continues to inform contemporary practices of social and economic exchange as they relate to consumer identity, as well as to current discourses about surveillance and privacy in a digital age. This article is based on a paper presented at the Media in Transition symposium (Utrecht, June 28, 2018), in the Industries and Infrastructures panel organised by Judith Keilbach.

Full textAbstract:
The current research analysed the existing literature on the electromagnetic spectrum influences and made significant contributions in the perspective of the ongoing insinuations of electromagnetic frequency radiation emitted from the novel 5G network technology installations. In this case, the contemporary 5G network technology was tested along ANALOGY1, ANALOGY 2 and ANALOGY3 to find out if 5G network does emit electromagnetic non-ionizing radiation capable of destroying human body cells as already alleged. The paper observed that deploying the standalone 5G network on unmodulated ultra-high frequency beyond 20Gigahertz will produce non-ionizable, non-visible radiation (electrons and protons interacting as fields) capable of adverse health effect including heating up the human skin through polarisation and dipolar moment urtication , thereby destabilising the equilibrium of the human DNA charged particles through the formation of free radicals that are highly reactive due to the presence of unpaired electrons that occurred when water molecules are broken within the human cell.

Full textAbstract:
The relevance of this article is determined by the growing ubiquitous digitalization of mediatized communications, including under the influence of the COVID-19 pandemic in 2020-2021. The consequence of this process is the transformation of the structure of social space and approval of virtual interaction as a basic method of communication - instead of interpersonal. These transformations entail institutional changes, manifested in axiological and normative transitions of communicative space, semantic restructuring of communications under the influence of changing social reality. Induced by the technological infrastructure of communication, a mediatized social reality emerges, which also entails semantic changes in communication. All these circumstances actualize the phenomenon of communicative competence of an individual, which determines the effectiveness of interactions in the context of technological, semantic and institutional changes. The article presents some outcomes of empirical verification of communicative competence in contemporary Russian interaction practices. The phenomenon of hybridization of communicative competence during the transition of a person from the environment of real communications to the environment of virtual communications, contributes to the construction of mediatized social reality and expands his social reality. This ability of an individual and his communicative competence for transgression, combined with hybridity, is a factor in the integration of the communicative space of society with its contradictory characteristics.

Introduction. The information environment of the society as an integral part of a human habitat is a factor of his health and must comply with safety requirements. As a result of the development of communication technologies on the basis of computer devices and the Internet, there have been significant changes in the information environment of the society and its impact on people. The study of the negative impact of the contemporary information environment on a human cannot be limited to physical and psychophysiological factors. A semantic component of the information itself is significant. Information environment has a negative impact on the cognitive and emotional sphere of his psyche. The object of information influence is the personality. The objective of the paper is to study the formation of the contemporary information and communication environment of the society, the trends in its development, to define its main components and psychological peculiarities. Material and methods. The method of investigation is a comparative analysis of the views of various authors and their theoretical generalization. Results. Based on the analysis of publications, a current understanding of the information and communication environment of the society is presented. The formation of the information environment is connected with the development of technologies and tools for fixing, preserving and transferring social experience. Six stages of the development of the means of the information transferring and preservation in the society are selected. Global informatization of the environment leads to the changes in people’s lives and activities. The picture of the human world, his worldview, his way of life are exposed to the effects of the information traffic. The risk factor is the deterioration of the human adaptation to new conditions. The changes within the individual do not keep up with the rapid changes in technology. Conclusion. In the context of the new information and communication reality the importance of the problems of human ecology was shown to increase. The information environment of a society as an object of the study can be considered in the following aspects: a) as a human habitat; b) as a means of information human activities; c) as a system of communications, including interpersonal ones; d) as an information infrastructure that provides storage, access and use of information arrays.

Present situation with riverside territories planning in many Russian cities, particularly in bigger scale in St. Petersburg and Moscow, might be characterized as quite problematic. Main reason for this situation is related with constantly increasing transport pressure, in fact noticeably reducing pedestrian accessibility because of riverside territories dense occupation by transit roads network. Instead forming ecologically balanced blue-green infrastructure for sustainable development providing, many big cities in Russia are losing riverside areas for population direct contact with the most attractive parts of urban landscape. Contemporary international experience is permanently presenting wide diapason of riverside territories management concepts realization and their humanly orientated strategies of adaptation for population sufficient using. Among the most topical aspects of riverside territories essential transformation such as optimally balanced pedestrian, bicycle and transport infrastructure creation, functions and landscape logical integration, widening of leisure activities infrastructure, water communications development and regeneration of riverside ecosystems could be marked.

Full textAbstract:
Volunteer Computing provision of seamless connectivity that enables convenient and rapid deployment of greener and cheaper computing infrastructure is extremely promising to complement next-generation distributed computing systems. Undoubtedly, without tactile Internet and secure VC ecosystems, harnessing its full potentials and making it an alternative viable and reliable computing infrastructure is next to impossible. Android-enabled smart devices, applications, and services are inevitable for Volunteer computing. Contrarily, the progressive developments of sophisticated Android malware may reduce its exponential growth. Besides, Android malwares are considered the most potential and persistent cyber threat to mobile VC systems. To secure Android-based mobile volunteer computing, the authors proposed MulDroid, an efficient and self-learning autonomous hybrid (Long-Short-Term Memory, Convolutional Neural Network, Deep Neural Network) multi-vector Android malware threat detection framework. The proposed mechanism is highly scalable with well-coordinated infrastructure and self-optimizing capabilities to proficiently tackle fast-growing dynamic variants of sophisticated malware threats and attacks with 99.01% detection accuracy. For a comprehensive evaluation, the authors employed current state-of-the-art malware datasets (Android Malware Dataset, Androzoo) with standard performance evaluation metrics. Moreover, MulDroid is compared with our constructed contemporary hybrid DL-driven architectures and benchmark algorithms. Our proposed mechanism outperforms in terms of detection accuracy with a trivial tradeoff speed efficiency. Additionally, a 10-fold cross-validation is performed to explicitly show unbiased results.

Full textAbstract:
This study proposes a modular water monitoring IoT system that enables quantitative and qualitative measuring of water in terms of an upgraded version of the water infrastructure to sustain operational reliability. The proposed method could be used in urban and rural areas for consumption and quality monitoring, or eventually scaled up to a contemporary water infrastructure enabling water providers and/or decision makers (i.e., governmental authorities, global water organization, etc.) to supervise and drive optimal decisions in challenging times. The inherent resilience and agility that the proposed system presents, along with the maturity of IoT communications and infrastructure, can lay the foundation for a robust smart water metering solution. Introducing a modular system can also allow for optimal consumer profiling while alleviating the upfront adoption cost by providers, environmental stewardship and an optimal response to emergencies. The provided system addresses the urbanization and technological gap in the smart water metering domain by presenting a modular IoT architecture with consumption and quality meters, along with machine learning capabilities to facilitate smart billing and user profiling.

The activities of the MNO (Mobile Network Operator) feature rapid development and business model innovations; one of their principal results is the communications infrastructure that is vital for economic growth. This dynamic and changing mode of operation (modus operandi) introduces high requirements for business decisions and overall informing to maintain competitiveness. One of the principal success factors in MNO activities is the application of contemporary information technologies, in particular technologies of business intelligence and analytics. The activities of MNO create large data volumes, leading to a significant potential discovery of insights from data. As a result, MNOs have been using analytical technologies to mine large data volumes for several decades, and experience accumulation started long before the term “big data” emerged in academia and business. The growing dynamics of activities drive the efficient use of analytical experience to boost competitive advantage. The goal of this paper is to define the most important features of the use of big data analytics in MNO business and any possible related challenges.

Full textAbstract:
The purpose of this chapter is to evaluate the effectiveness of marketing communications in promoting tourism on the Greek island of Myconos. The research evaluates the effectiveness of the marketing communications used by public bodies to promote Myconos in Europe. The research location was the airport at Myconos. The researchers used a probability sampling technique in the form of stratified random sampling, since the population used for the research was multinational. Four-hundred questionnaires were gathered from a research population of 8000. The percentage of arrivals pertinent to each subset (tourist population divided by nationality) was compared with the total number of tourists who arrived on Myconos from the countries constituting the sampling frame, and the number of questionnaires to be given to each of the subsets was calculated. The study shows that marketing communications had a positive effect on the overall business performance and improved it noticeably. Marketing communications used by public bodies to promote Myconos were effective as they increased tourism arrivals and influenced the majority of the tourists to visit it. In addition to this, the study shows that there are factors such as tourists' origin, age, and annual income that affect the effectiveness of marketing communications. It also identified that tourists value a marketing strategy that involves analytical information about the tourism destination, as they stated that brochures, guidebooks, and the Internet influenced them to a great extent.

This chapter introduces a group of 121 women, men, and children on the island of Madagascar that formally converted to Judaism in mid-May 2016. It discusses the Westerners before the conversions that had only vague and second-hand notions about the proselytes' difficulties in maintaining a religiously observant lifestyle in a country that has been plagued with endemic corruption and barely functioning infrastructure for decades. It analyses how the 121 Malagasies relied upon faith in the efficacy of the culture of digital communications, which they had harnessed since 2013 in order to prepare for the conversions. The chapter focuses on kelal yisra'el, the worldwide Jewish community that was facilitated by the globalized matrix of mass communication and enabled the learning of post-exilic Judaism. It identifies the groups of contemporary 'internet Jews' from the developing world, such as the Igbo of Nigeria and the Beth Yeshourun community of Cameroon.

Full textAbstract:
Next-generations of wireless communication systems (5G scheme & beyond) are rapidly evolving in the contemporary life. These schemes could propose vital solutions for many existing challenges in various aspects of our lives, eventually to ensure stable communications. Such challenges are even greater when it comes to address ubiquitous coverage and steady interconnection performance in fast mobile vehicles (i.e., trains or airplanes) where certainly blind spots exist. As an early initiative, the Third Generation Partnership Project (3GPP) has proposed a regulation for Long Term Evolution (LTE)-based Vehicle-to-Everything (V2X) network in order to offer solid solutions for V2X interconnections. V2X term should comprise the following terminologies: vehicle-to-vehicle (V2V), vehicle-to-network (V2N) communications, vehicle-to-infrastructure (V2I), and vehicle-to-pedestrian (V2P). Superior V2X communications have a promising potential to improve efficiency, road safety, security, the accessibility of infotainment services (any service of user-interface exists inside a vehicle). In this chapter, the aforementioned topics will be addressed. In addition, the chapter will open the door on investigating the role of wireless cooperative and automatic signal identification schemes in V2X networks, and shedding light on the machine learning techniques (i.e, Support Vector Machines (SVMs), Deep Neural Networks (DNNs)) when they meet with the next-generations of wireless networks.

Full textAbstract:
Access networks are usually termed “last-mile/first-mile” networks since they connect the end user with the metro-edge network (or the exchange). This connectivity is often at data rates that are significantly slower than the data rates available at metro and core networks. Metro networks span large cities and core networks connect cities or bigger regions together by forming a backbone network on which traffic from an entire city is transported. With the industry achieving up to 400 Gbps of data rates at core networks (and increasing those rates [Reading, 2013]), it is critical to have high-speed access networks that can cope with the tremendous bandwidth opportunity and not act as a bottleneck. The opportunity lies in enabling services that can be of benefit to the consumers as well as large organizations. For instance, moving institutional/personal data to the cloud will require a high-speed access network that can overcome delays incurred during upload and download of information. Cloud-based services, such as computing and storage services are further enhanced with the availability of such high-speed access networks. Access networks have evolved over time and the industry is constantly looking for ways to improve their capacity. Therefore, an understanding of the fundamental technologies involved in wired and wireless access networks will help the reader appreciate the full potential of the cloud and cloud access. Against the same backdrop, this chapter aims at providing an understanding of the evolution of access technologies that enable the tremendous mobility potential of cloud-based services in the contemporary cloud paradigm.

Full textAbstract:
The process of establishing appropriate institutional frameworks and information and communication technology (ICT) infrastructure backbones to support future development of e-democracy is not an easy task. Botswana has started building its e-democracy institutions as it accords citizens the opportunity to participate in the democratic process using appropriate ICT platforms out of the realization that participatory democracy is crucial in placing a country at a competitive edge in the contemporary global socio-economic value chains. Towards this goal, the first initiative has been the establishment of the e-government taskforce team, which has been mandated with the development of an e-government strategy commensurate with Botswana’s local context. The establishment of the e-government taskforce team has been done in tandem with putting in place appropriate ICT infrastructures and legal, institutional, or regulatory frameworks. This chapter presents an exploratory study that aims to discuss the different interventions that are being put in place by the Botswana government and its co-operating partners as setting the foundation for implementing full-scale e-democracy applications such as e-forums and e-voting. The chapter also presents obstacles and challenges that have not been met, insofar as building virtual public spheres in the realm of participatory e-democracy in Botswana is concerned. Attention is given to how virtual public spheres should be used as collaboration and networking platforms both in the private and public sectors of Botswana. It is anticipated that the different approaches that have been employed by Botswana towards this course may prove useful to other emerging nations who may have intentions of implementing ICT infrastructure and encouraging virtual public spheres as a means to building viable e-democracy.

Full textAbstract:
The covid-19 pandemic has brought about new ways of conducting business through the use of Information Communication Technologies and elections have not been spared either. Internet voting is another form of strengthening democracy through the use of Information Communication Technologies. Africa lags in the implementation of electronic voting, especially Internet voting. This chapter applied a critical socio-technical analysis that analyses factors that influence the applicability of Internet voting within the African context. The researcher applied desktop research which included 30 journals to gather data from the Internet and other documentation sources. The findings reveal that decision-makers can partially implement Internet voting in some of the countries in Africa like Kenya, Libya, Nigeria, Morocco, Mauritius, Tunisia, and Seychelles. To successfully implement Internet voting, the decision-makers in African nations have to fully invest in the Information Communication Technology infrastructure, provide the necessary security, legislation and carry out intensive voter education to build trust among voters.

Full textAbstract:
An infrastructure-based mobile environment is formed with a wireless network connecting mobile hosts (MHs) and mobile support stations (MSSs). MHs are clients equipped with portable devices, such as laptops, personal digital assistants, cellular phones, and so on, while MSSs are stationary servers providing information access for the MHs residing in their service areas. With the recent widespread deployment of contemporary peer-to-peer (known as P2P throughout this chapter) wireless communication technologies, such as IEEE 802.11 (IEEE Standard 802-11, 1997) and Bluetooth (Bluetooth SIG, 2004), coupled with the fact that the computation power and storage capacity of most portable devices have been improving at a fast pace, a new information sharing paradigm known as P2P information access has rapidly taken shape. The MHs can share information among themselves rather than having to rely solely on their connections to the MSS. This article reviews a hybrid communication framework - that is, mobile cooperative caching - which combines the P2P information access paradigm into the infrastructure-based mobile environment.

Full textAbstract:
This chapter provides a clear conceptual discussion on the recent developments in the Financial Statement Analysis (FSA). It presents how IFRSs changed the outlook of the financial reporting and the analysis and explains the key points that should be considered in FSA. Using a case study on the financial reports of Turkcell, a communication and technology company listed both on the New York Stock Exchange (NYSE) and the Borsa Istanbul (BIST), the differences between IFRSs and U.S. GAAP accounting standards in the measurement of overall financial performance and position are documented. Overall findings show that IFRSs change the appearance of financial statements significantly. While IFRS reporting extenuates “the bottom line” it accentuates total assets with higher shareholder equity compared to U.S. GAAP. This chapter might be a practical guide for users, preparers, and regulators to understand the cosmetic impact of IFRSs on financial statements.

Various contemporary information and communication technologies (ICT) have revolutionized the global computing environment. This impacts most companies, especially traditional stand-alone ERP systems are inadequate to handle the current requirements of logistics applications. This paper studies the integration of RFID and mobile technologies with web-enabled applications to an existing in-house ERP system. This enables management to utilize accurate information for analyzing their business performance and then perform any other further decisions quickly. Benefits include retrieving information more easily, reducing order processing and delivery time, increasing sales performance, enhancing communication with customer, and improving data accuracy for in-house ERP System. In particular, the authors illustrate how this infrastructure can help the integration of logistic processes and the handling of exceptions in key business processes. The authors further evaluate the approach with respect to the requirements of key system stakeholders.

Contemporary Photonic Integrated Circuit (PIC) packages within the communications network infrastructure have reached a thermal limit. Integrated packages involving microfluidic channels are an appealing development to improve the thermal design of future PIC packages, to significantly improve the removal of heat fluxes in order to sustain the expected enhanced data traffic growth. The Thermally Integrated Smart Photonics Systems (TIPS) project aims to develop and demonstrate a thermally enabled integrated platform that is scalable, to meet the predicted data traffic demands. Full system integration requires an integrated pumping solution, therefore a primary heat exchanger that can deliver the required thermal performance with a low pressure drop (ΔP) is needed. A channel containing a single array of cylindrical posts offers a low pressure drop, similar to a large hydraulic diameter minichannel. Local destabilization of the flow would provide heat transfer enhancement. In particular, non-Newtonian fluids have been shown to exhibit significant mixing in such configurations. Micro Particle-Image Velocimetry (μPIV) measurements were taken for Newtonian and viscoelastic fluids within this channel. Instabilities associated with the viscoelastic fluid were recorded immediately upstream of the post array. This flow exhibited almost a four-fold increase in mixing at comparable flow rates to the Newtonian fluid tested. This suggests that the Nusselt number enhancement associated with such flows could increase the heat transfer rates quite significantly in microchannels containing obstructions.

Optical networks are a critical element of contemporary communications infrastructure, due to their efficacy in transmitting high-speed data over large distances. Photonic integrated circuits (PICs) offer compelling advantages in terms of performance and miniaturization, but the increase in power density of these components, coupled with shrinking packaging restrictions, presents a significant thermal management challenge. This has driven the need for the integration of liquid-based microfluidic cooling artefacts into next generation PIC packages. Liquid micro-jets are emerging as candidate primary or secondary heat exchangers for such packages, however the thermal behavior of confined, low Reynolds number liquid slot jets is not comprehensively understood. This investigation utilized a hot foil technique to experimentally determine the influence of implementing jet outlet modifications — in the form of tabs and chevrons — as techniques for passive control and enhancement of single-phase convective heat transfer. The investigation was carried out for slot jets in the laminar flow regime, with a Reynolds number range, based on the conventional slot jet hydraulic diameter, of 100 to 500. The investigation was carried out with a slot jet aspect ratio of 4, and a fixed confinement height to hydraulic diameter ratio (H/Dh) of 1. It was found that all outlet modifications increased local and area-averaged Nusselt number compared to a conventional slot jet. Modifications to the major axis (or long edge) of the slot jet were most effective, achieving increases in area-averaged Nusselt number of up to 61%. It was also determined that the location and magnitude of Nusselt number peaks within the slot jet stagnation region, could be passively controlled and enhanced through the application of outlet tabs at varying locations, allowing for more flexible targeted hotspot cooling. Therefore, it was concluded that enhancements in an integrated microjet cooling artefact can be achieved through passive geometry devices, without compromising the stringent packaging restrictions of such systems, such as confinement height and nozzle geometry.

The contemporary conjuncture of widespread ecological and social crises summons critical thinking about significant cultural changes in digital media design. The selection and classification practices that marked the history of slavery and colonization now rely on all types of nanotechnologies. On behalf of the future, bodies became expanded territory to sovereign intervention, where the role of contemporary powers enable extraction and mining of material, plumbed from the most intimate sphere of the self. This logic requires the state of exception to become the norm, so that the crisis is the digital media’s critical difference: they cut through the constant stream of information, differentiating the temporally valuable from the mundane, offering users a taste of real-time responsibility and empowerment. Thereby, this research aims to explore the dynamic transformations of the mediatic environment and their impacts on the fundamental relationships of human beings with the world, the self, and objects. It unfolds concerns around neocolonial assaults on human agency and autonomy that resonate from structuring patterns emerging from the digital infrastructure of neoliberalism and the relationships of human beings with the world. It disputes the imaginaries, representational regimes, and the possibilities of reality perceptions with universal, patriarchal, and extractive representations. This research also seeks alternative forms of media education and political resistance through its collaborative practice, pursuing an attentive and open-ended inquiry into the possibilities latent for designing new communication and information tools within lived material contexts: How might we represent invisible media infrastructures? How to produce knowledge about this space and present it publicly? How can these representations be politically mobilized as ecological and social arguments to establish a public debate? How can artistic sensibilities, aesthetics and the visual field influence what is thought of this frontier space? Finally, how can art, play and research intervene and participate? For this, the project involves participatory methods to create spaces for dialogue between different epistemologies, questioning the forms of ethical and creative reasoning in the planetary media and communication systems; for fostering the techno-politics imagination through playful, participatory futures and transition design frameworks as an ethical praxis of world-making; and for a reconceptualization of autonomy as an expression of radical interdependence between body, spaces, and materiality. The research aims to provide a framework for designing media tools, which incorporates core design principles and guidelines of agency and collective autonomy. It also engages with the transnational conversation on design, a contribution that stems from recent Latin American epistemic and political experiences and struggles, and the wider debate around alternative forms of restoring communal bonds, conquering public discussion spaces, and techno-political resistances through collaborative research practices and participatory methods.

In 4th International Conference of Contemporary Affairs in Architecture and Urbanism – Full book proceedings of ICCAUA2020, 20-21 May 2021.

Full textAbstract:
Technological developments such as the extensive use of modern communication tools and increasing infrastructure opportunities have changed the spatial organization forms and daily life practices in cities. Previously, central place theory, which explains hierarchical urban patterns based on the minimum population size-based threshold concept and the maximum distance-based range concept has become incompetent to explain the spatial organization of today's settlements. At this point, in defining the urbanization processes and explaining the spatial organization, the search for new conceptual and methodological approaches has become important. In this study, changing urban systems are evaluated in terms of closeness centrality, attribute centrality, network centrality, and geographical centrality based on space of flows and interpreted by current parameters. It is concluded that in defining the structure and spatial organization of urban systems, the morphological and functional dimensions of urban systems should be evaluated besides the parameters of population, geographical proximity or network relations. In this context, a model proposal has been developed by using current parameters such as density, diversity, mobility, connectivity, spatial-temporal structure, and urban networks.

Full textAbstract:
The main recommendations of the panel report can be summarised under four key headings: High quality, high impact research: the importance of archaeological science is reflected in work that explores issues connected to important contemporary topics, including: the demography of, the nature of movement of, and contact between peoples; societal resilience; living on the Atlantic edge of Europe; and coping with environmental and climatic change. A series of large-scale and integrated archaeological science projects are required to stimulate research into these important topics. To engage fully with Science in Scottish Archaeology iv these questions data of sufficient richness is required that is accessible, both within Scotland and internationally. The RCAHMS’ database Canmore provides a model for digital dissemination that should be built on. Integration: Archaeological science should be involved early in the process of archaeological investigation and as a matter of routine. Resultant data needs to be securely stored, made accessible and the research results widely disseminated. Sources of advice and its communication must be developed and promoted to support work in the commercial, academic, research, governmental and 3rd sectors. Knowledge exchange and transfer: knowledge, data and skills need to be routinely transferred and embedded across the archaeological sector. This will enable the archaeological science community to better work together, establishing routes of communication and improving infrastructure. Improvements should be made to communication between different groups including peers, press and the wider public. Mechanisms exist to enable the wider community to engage with, and to feed into, the development of the archaeological and scientific database and to engage with current debates. Projects involving the wider community in data generation should be encouraged and opportunities for public engagement should be pursued through, for example, National Science Week and Scottish Archaeology Month. Networks and forums: A network of specialists should be promoted to aid collaboration, provide access to the best advice, and raise awareness of current work. This would be complemented by creating a series inter-disciplinary working groups, to discuss and articulate archaeological science issues. An online service to match people (i.e. specialist or student) to material (whether e.g. environmental sample, artefactual assemblage, or skeletal assemblage) is also recommended. An annual meeting should also be held at which researchers would be able to promote current and future work, and draw attention to materials available for analysis, and to specialists/students looking to work on particular assemblages or projects. Such meetings could be rolled into a suitable public outreach event.
