The widespread application of wireless communication technology brings great convenience to people, but security and privacy problems also arise. To assess and guarantee the security of wireless networks and user devices, discovering and identifying wireless devices become a foremost task. Currently, effective device identification is still a challenging issue, as device fingerprinting requires huge training datasets and is difficult to expand, and rule-based identification is not accurate and reliable enough. In this paper, we propose WND-Identifier, a universal and extensible framework for the identification of wireless devices, which can generate high-precision device labels (vendor, type, and product model) efficiently without user interaction. We first introduce the concept of device-info-related network protocols. WND-Identifier makes full use of the natural language features in such protocol messages and combines with the device description in the welcome page, thereby utilizing extraction rules to generate concrete device labels. Considering that the device information in the protocol messages may be incomplete or forged, we further take advantage of the application logic independence and stability of the device-info-related protocol, so as to build a multiprotocol text classification model, which maps the device to a known label. We conduct experiments in homes and public networks and present three application scenarios to verify the effectiveness of WND-Identifier.

Internet of Things(IOT) is the rising innovation without bounds is required to associate billions of devices. IoT is the future where many low power resources and constrained devices are connected by means of the internet for communication, compute process and take actions in the communication network. The increased number of communication is relied upon to produce heaps of information and the security of information can be a threat resulting a secure solution for communication is necessitates among heterogenous devices. Focus of the work is to provide confidentiality, authentication and integrity of data in transit between IoT edge devices and back-end systems. This paper proposes a lightweight hybrid encryption system using ECDH key exchange mechanism for generating keys and establishing connection, digital signature for authentication, thereafter AES algorithm for encryption and decryption of user data file. The proposed combination is referred to as “three way secured data encryption mechanism” which interpret all the 3 protection schemes of authentication, info security and verification with the characteristics of lower calculation cost and faster speed makes it robust for hackers to crack the security system, thereby protective data in transmission.

Certain technological improvements mean the obvious rethinking of the boundaries of the private sphere. This process has made a legislative response necessary. In this sense, Act LIII of 2018 can be highlighted, which states in its preamble that the modern devices of info communication have laid new foundation for the everyday communication, hence the protection of private life extends beyond the physical harassment to Internet. An important factor in the protection of privacy is the responsibility of companies, which must ensure the protection of the privacy rights of entities using their online interfaces.

In this work, a cheaper alternative method of determining path loss using Network cell info lite software is proposed. Hata-Okumura model is used in the determination of path loss and signal strength of mobile communication devices within Ibogun and Ifo, a suburban community in Ogun state, Nigeria. Additionally, this paper is also aimed at determining the path loss under transmission line to ensure proper network planning in areas covered by transmission lines. Result obtained shows that areas with pylons have greater path loss compared to areas with no pylons. It is recommended that the power levels of base station operating in this area should be increased.

The emergence of the new digital platforms, a diversified number of approaches and providers cannot damage too much a rather crowded info sphere. What may come as a general challenge is the “performance” amateurs who have the devices, the will but not the skills to become reliable communicators. Good training and an expanded concern for the accuracy of messages should distinguish between fact and fiction and between information and opinion. The smart phone, the iPod, the lap top or the tablet have expanded the means of communication. They have also diversified the types of messages circulated. The traditional main stream media outlets are facing a mounting competition from the social networks populated with the folk journalists, albeit, non-professionals. Basic training of all those willing to come into the communication ring and regulations that may concern not only the professionals but also the amateurs, may be ways to get over what seems to be a deadlock.

IoT devices (sensors, drones, cameras) are gaining more and more emphasis on military operations. The application of IoT elements in the military environment increases situational awareness and supports the acquisition and maintenance of information superiority. The information they provide about the enemy, the area of operations, and the location and status of our soldiers and assets can contribute to the successful execution of operations at the tactical, operational and strategic levels. However, they can also pose serious threats if their vulnerabilities allow the data they collected to leak or they provide access to the info-communication networks used for the enemy. In this article, the author examined the vulnerabilities of these IoT devices using keyword analysis. After drawing conclusions from the analysis of the relevant literature, he compared the results with the general-purpose IoT threats and attacks typical of today, like distributed denial of service attacks, security, software, security and privacy issues.

Advances in the info and communication knowledge have led to the emergence of Internet of things (IoT). Internet of things (loT) is worthwhile to members, trade, and society seeing that it generates a broad range of services by interconnecting numerous devices and information objects. Throughout the interactions among the many ubiquitous things, security problems emerge as noteworthy, and it is significant to set up more suitable solution for security protection. Nonetheless, as loT devices have limited resource constraints to appoint strong protection mechanisms, they are vulnerable to sophisticated security attacks. For this reason, a sensible authentication mechanism that considers each useful resource constraints and safety is required. Our proposed scheme uses the standards of Elliptic Curve digital signature scheme and evaluates systematically the efficiency of our scheme and observes that our scheme with a smaller key size and lesser infrastructure performs on par with the prevailing schemes without compromising the security level.

Background: Software-Defined Radio (SDR) frameworks from cellular telephone base stations, e.g., Multiservice Distributed Access System (MDAS) and small cells, employ extensively integrated RF agile transceivers. The Internet of Medical Things (IoMT) is the collection of medical devices and applications that connect to healthcare IT systems through online computer networks. Medical devices equipped with Wi-Fi allow M2M communication, which is the backbone of IoMT and associated devices linked to cloud platforms containing stored data to be analyzed. Examples of IoMT include remote patient monitoring of people with chronic or long-term conditions, tracking patient medication orders and the location of patients admitted to hospitals, and patients' wearables to send info to caregivers. Infusion pumps connected to dashboards and hospital beds rigged with sensors measuring patients' vital signs are medical devices that can be converted to or deployed as IoMT technology. Methods: This work proposes an SDR architecture to allow wireless High-Definition (HD) video broadcast for biomedical applications. This text examines a Wideband Wireless Video (WWV) signal chain implementation using the transceivers, the data transmitted volume, the matching occupied RF bandwidth, the communication distance, the transmitter’s power, and the implementation of the PHY layer as Orthogonal Frequency Division Multiplexing (OFDM) with test results to evade RF interference. Results: As the IoMT grows, the amount of possible IoMT uses increases. Many mobile devices employ Near Field Communication (NFC) Radio Frequency Identification (RFID) tags allowing them to share data with IT systems. RFID tags in medical equipment and supplies allow hospital staff can remain aware of the quantities they have in stock. The practice of using IoMT devices to observe patients in their homes remotely is also known as telemedicine. This kind of treatment spares patients from traveling to healthcare facilities whenever they have a medical question or change in their condition. Conclusion: An SDR-based HD biomedical video transmission is proposed, with its benefits and disadvantages for biomedical WWV are discussed. The security of IoMT sensitive data is a developing concern for healthcare providers.

This article deals with the new configurations of information and communication in the domain of health knowledge in Brazil, by the intercurrence of two concomitant factors: the increasingly powerful increment of technical mediations in the digital environment; the health crisis caused by the pandemic of the new coronavirus - the SARS-CoV-2. To study the domain at this critical moment, we considered the scientific society that represents it - the Brazilian Association of Collective Health (Abrasco) - and the way it promoted communication among peers in the scientific field and between them and society, through the "Abrasco Agoras", a set of webinars bringing together researchers, professionals, health authorities, representatives of organizations and social movements to discuss the issues related to the pandemic moment. We started with a theoretical treatment of Domain Analysis, to then approach the new modalities of scientific info-communication in the era of E-science and pandemic. The results of the analysis of a sample of the "Abrasco Agoras" show that the intensive use of digital devices and the accelerated rhythm of scientific knowledge production demand reflections on the health domain that take into account the very way of functioning of the scientific field, the status of researchers and health professionals, the processes of production, mediation, diffusion and appropriation of knowledge, the modes of information and communication among peers and between peers and society.

Abstract One of the most dynamically evolving sectors of our days is eHealth. More and more applications, software, devices, etc. are launched that make healthcare segments accessible not only for professionals but for laics, too. This study examines to what extent the adult Hungarian population of Mureş County is ready to become eHealth participative, i.e. an active agent of its own healthcare attendance, in order to make use of the advantages offered by modern technologies that provide information and help understand our diseases, their prevention, and health maintenance. The probability of eHealth usage is approximated by the frequency of Internet usage. Social determinants of info-communication tool usage are assessed, controlling for covariates. Age has the strongest impact upon the frequency of Internet usage. The younger is the respondent, the more likely he/she is to be a frequent user, and, apart from this, only the educational level determines Internet use, higher education implying more frequent usage.

The area of transmission compression is gaining a quick momentum by evolving with completely different varieties of compression protocols and coding method. However, majority of the prevailing communication devices still uses H.264 as a customary compression protocol. we tend to reviewed a number of the prevailing system touching on usage of H.264 in video compression to explore it doesn’t supply process effectiveness though it's going to supply higher reconstructed knowledge on the receiver finish. This paper introduces A distinctive optimisation mechanism to optimize the coding time by introducing a value perform formulation. The bestowed design runs over typical H.264 and supply worth additional advantage by creating it additional resource friendly. The rule made uses MPEG file as AN input that endure the method of optimisation of coding time used for coding I and P frame. The study outcome of the projected system is found to supply a much better reduction in coding time as compared to existing mechanism of Lagrangian price perform. As a contribution, our outcome shows a much better equilibrium between the info quality of reconstructed signal and therefore the coding time.

According to existing forecasts, after 2030, an intelligent, three-dimensional, ultra-dense, integrated, terabyte, terahertz, tactile, and touch-scanning wireless communication system of the sixth generation (6G) will be deployed. Spatial features will be very significant for it, which necessitates geographical research. Therefore, an attempt has been made to determine the future directions of the geographical study of 6G networks based on a comparison of network parameters with the existing experience of knowing the spatial and temporal features of the deployment of information and communication networks. The main attention is paid to the infrastructure and the telecommunication services. The infrastructure includes cloud data centers, stationary and mobile base stations, subscriber and robotic devices, radiating surfaces, sensors, and other network elements. Future services will be represented by ubiquitously connected artificial intelligence, sensory scanning of the environment, holographic telepresence, augmented reality, tactile communication, three-dimensional positioning, and other services. It is proposed to develop geographical research in the following areas: deployment of a spatially distributed network; info-communication-network development of space; identification of “smart” agglomerations and regions; spatial diffusion of telecommunications services; center-peripheral digital inequality; and artificial intelligence specialization of regions. Applied work is proposed to be carried out on the geographical expertise of network projects, optimization of the linear-node structure and recommendations of the 7G network parameters. For each of the nine directions, general characteristics and possible division into particular directions are given. Within the framework of the selected directions, the proposed periodization of the main research tasks is shown from the development of a methodology for geographical cognition of 6G networks in the 2020s to obtaining empirical results in the 2030s and their subsequent discussion for the transition to 7G in the 2040s.

Patient signals produced from a physical device, such as electrocardiography (ECG), which records the electrical activity of the heart, are vulnerable to keep noise due to various physical constraints of acquisition devices. It is critical for the detection and diagnosis of a variety of diseases. An ECG signal should be displayed as clean and clear as feasible due to its relevance in assisting physicians and doctors in making appropriate judgments. ECG is vulnerable to many types of noise because it is an electrical signal. To improve the quality of assistance for consumers Info a surveillance system by cooperative surveillance systems, high-quality data processing by the observed surveillance systems is required, which predetermines the requirement for high noise immunity of the latter. At the same time, the basics of building cooperative surveillance systems as a network of two-channel asynchronous information communication systems which include numeral of transmitting and receiving process using diverse frequency limits for reception and transmission, failure-prone open single-channel queuing systems, and request signals do not allow to provide the required the noise resistance of the systems under consideration. This paper first gives a characterization of request and interference signal flows in cooperative surveillance systems and briefly examines the features of request signals and their effect on the immunity of cooperative surveillance systems. Then, it calculates the noise resistance of the demand signals of the cooperative surveillance systems for the probabilities of errors: signal skipping; First- and second-degree false alarms in the case of unrelated events, unintended and intra-system impulse interferences in the request channel

The article deals with issues of countering cyber-attacks (so-called trolling and hacking) in Internet broadcasting, and using social networks in info-competition and communication discourse in German-language on-air, by the example of International News Agency “Russia Today” (RT) and its website Sputnik. The topicality of the article is based on the fact that RT’s website Sputnik is a relatively new resource on the European information market. The author analyzes the cases and contexts of countering malware and targeted cyber-attacks on European German-language broadcasting agencies. The study of RT’s and Sputnik’s journalists’ work shows that it is actively hindered by some Western countries, particularly the USA and the UK, which are obsessed by anti-Russian xenophobia and the unproved pre-conception of Russia’s interference with their internal affairs. These countries openly admit to be waging an outreach war against Russian broadcasting companies by means of hacking attacks. Russian multi-language broadcasting channel RT, founded in 2005, successfully reflects and transmits Russia’s official position on key issues of the international politics and countering cyber-attacks by foreign “trolls” and “hackers”. A website is currently the most easily accessible among all digital communication channels, and its quality is easy to assess. Considering this, the author describes advantages of RT’s transition from social networks to its German-language site Sputnik. The measures taken in order to optimize its structure, adapt to mobile devices, and provide convenience of site navigation, enabled Sputnik to enlarge its geographic reach and enter the circle of foreign German-language social networks. Keywords. Internet broadcasting, broadcasting, cyber-attacks, information war, trolling, hacking, German-speaking audience, management of news, International News Agency “Russia Today” (INA RT), website Sputnik, Internet media, social networks, RIA Novosti.

The article explores approaches to the definition of the concepts of «business» and «e-business». In the study of different approaches to the definition of e-business and e-commerce, only those considering e-commerce as one of the areas of e-business were chosen. e-Business belongs to all forms of use of digital information and communication technologies designed to support or increase the efficiency of sales processes both at the stage of preparation and at the stages of negotiations and implementation. The interpretation of the category of «e-commerce» by modern researchers is considered, the areas of e-commerce are defined. The term «e-commerce» stipulates that companies and individuals can buy and sell goods and services over the Internet. It can be carried out using computers, tablets, smartphones and other intelligent devices. e-Business models are analyzed, e-business classification is examined, concerning the following: intermediary model, advertising model, info-intermediary model, seller model, manufacturer model, partner model, community model, subscription model, and practical model. The advantages and disadvantages of e-business are determined, which will allow not to lose the opportunities provided and to develop measures to maximize the leveling of weaknesses. Thus, the advantages of e-business are associated with the implementation of its main goal – the creation of electronic value, that is, the generation of electronic added value. The main stages of creating the value of an electronic information product have been determined

Rapid progress of computing and info-communication technologies (ICT) has changed the ecosystem of power production and delivery. Today, an energy network is a complex set of interrelated devices and information systems covering all areas of electric power operations and applying ICT based on open standards, such as IEC 60870, IEC 61850, and IEC 61970. According to IEC 62351, the energy networks are faced with high cybersecurity risks caused by open communications, security requirements rarely considered in the energy facilities, partial and difficult upgrades, and incompatibility of secure tools with industrial solutions. This situation results in new security challenges, e.g. denial of service attacks on the connected controllers, dispatching centers, process control systems, and terminals. IEC 62351 describes possible ways to comprehensive security in the energy networks. Most of them used in traditional networks (e.g., firewalls, intrusion detection systems) can be adapted to the energy networks. Honeypot systems as a protection measure help us to mitigate the attacks and maintain necessary security in the networks. Due to the large scale of an energy network and heterogeneity of its components, a new design, deployment, and management strategy for the honeypot systems are required. The paper suggests a new method for organizing a virtual network infrastructure of a hybrid honeypot system and a dynamic management method that adapts the network topology to the attacker’s actions according to the development graph of potential attacks. This technique allows us to dynamically build virtual networks of arbitrary scale. Because of the similarity of the virtual network to the virtualized origin and providing the level of interactivity of its nodes corresponding to real devices, this technique deploys an energy network indistinguishable from the real one for the attackers. A prototype of our honeypot system has been implemented, and experiments on it have demonstrated the more efficient use of the computing resources, the faster reaction to the attacker’s actions, and the deployment of different sizes of virtual networks for the given limits of the computing resources.

Abstract With the number of connected-devices increasing tremendously, communication data rates are projected to be at least 10–100X in the 5G/mm-wave (MMW) technology - much higher than the existing 4G LTE connections.[1], [2] To catch up with the trend, novel packaging technology in the MMW frequency range is required, which will address fundamental MMW technical challenges such as high dielectric loss, degradation of quality factors in passives, increased parasitic, dramatically-enhanced electromagnetic interference, and the reduced radiation efficiency of antenna arrays. State-of-the-art approaches being pursued include organic-core substrates that have a low dielectric constant (Dk) and low dissipation factor (Df) such as fluorine based or liquid-crystal polymer (LCP) substrates in order to achieve enhanced antenna performance and low signal dissipations. These organic-based substrate technologies, however, can neither miniaturize packages nor handle precision signal routings that enable high density packages. To address these challenges, attention is focused on Fan-Out Wafer Level Package (FOWLP) technologies, like eWLB, InFO, and SWIFT, where integrated circuits (ICs) are embedded in epoxy molding compound. [3]–[6] Recently, glass-panel embedding (GPE) technology is emerging as an ideal packaging methodology that enables superior performance along with small form factor, ultra-low-loss, high density, ultra-short interconnects, and low cost. [7] These benefits stem from the advantages of using glass which has excellent properties such as ultra-smooth surface for precision redistribution layer (RDL), exceptional dimensional stability for panel-scalability and tailorability of CTE that allow direct board-attach for improved system performance. In addition, utilizing the epoxy molding compounds as encapsulation material allows the GPE package to be thinner and more robust package with small farm factor. Molding of glass cavity panels also helps with the handling of ultra-thin glass which is seen as a bottleneck towards glass based packaging solutions in production. These facilitates enhanced throughput by allowing more cavity cut outs (more coupons) per panel. This paper presents the first demonstration of ultra-thin GPE with sheet type epoxy molding compound (SMC) for 5G/mm-wave applications. First part of this paper discusses the process-flow used in glass-panel embedding with laminated SMC, including chip placement in glass cavities, lamination of SMC, and the reliability of the package architecture. This paper reports on such a demonstration in 60 μm glass substrates with 40 μm thickness SMC. The second part of this paper focuses on low-loss interconnects for 5G/mm-wave applications and presents the process development of signal routings such as transmission lines and microvias in RDLs as well as through-package vias (TPVs) with via-in-via process. The results suggest that the ultra-thin GPE architecture is a promising packaging technology solution for a variety of applications including high-frequency communications and high-performance computing.

Peer-review under responsibility of 3rd Asia International Multidisciplanry Conference 2019 editorial board (http://www.utm.my/asia/our-team/) © 2019 Published by Readers Insight Publisher, lat 306 Savoy Residencia, Block 3 F11/1,44000 Islamabad. Pakistan, info@readersinsight.net This is an open access article under the CC BY-NC-ND license (http://creativecommons.org/licenses/by-nc-nd/4.0/). _________________________________________________________ Research Highlights The study is dealing with the product implementation of mobile learning media for Arabic lesson by utilizing android communication tool with offline operational system. This is to explore the effectiveness of mobile learning media towards students’ Arabic lesson achievement. Data collection was carried out using pre-test and post-test with multiple choice test instrument. To analyze the data, the paired samples t-test was employed and it was obtained that the value of tcritical= 14.342 while the value of ttable = 2.086 at a significant level of α = 0.05. This means that tcritical = 14.342 > ttable = 2.086. Thus, H0 is rejected and H1 is accepted. As such, it can be concluded that the implementation of mobile learning media for Arabic lesson is highly effective to improve students’ achievement at Madrasah Aliyah (Islamic senior high school) in Lampung, Indonesia. Research Objectives This study is aimed at finding out the effectiveness of mobile learning media towards students’ achievement of Arabic lesson at Madrasah Aliyah in Lampung, Indonesia. The findings are expected to theoretically and practically bring benefits to researchers, teachers, students and readers in terms of 1) contributing mobile learning media for a more effective Arabic lesson, 2) providing an independent learning source for students in line with technology advancement, 3) assisting teachers to create effective, efficient and innovative instruction, 4) being researchers’ valuable experience to contribute to education by optimizing the instructional media for Arabic lesson in the era of industry revolution 4.0. Instructional media is a communication tool to make the learning process more effective (Yetri, Koderi, Amirudin, S Latifah, 2019). The benefits of using mobile learning in general are: 1) more affordable than buying PCs and laptops, 2) more diverse and varied in delivering the learning material, 3) encouraging the teachers to carry out continuous learning because students always have their smartphones on them, 4) lowering the cost of the learning process because it does not have to be conducted in class, 5) having a better potential in providing experiential learning, 6) increasing literacy, 7) increasing the number of participants in education, and 8) having more communication features because they are able to send text, audio, and audio-visuals between mobile phones (Mehdipour, 2013). Materials and Methods The study belongs to implementation research (Experimental Research). The independent variable is mobile learning media, while the dependent one is students’ achievement of Arabic lesson at Madrasah Aliyah in Lampung, Indonesia. The sample, a group of 35 students in class IX IPA as the experimental class, was taken using purposive random sampling technique. The study was conducted at Madrasah Aliyah Negeri 2 Bandar Lampung for 5 sessions in the odd semester of 2018/2019 academic year. Data were collected using test, observation, documentation and interview. Before implemented, the instruments had been validated by the experts of content and language to assure the content and construct validity. Data analysis was executed by comparing the scores of pre-test and post-test using the paired samples t-test. Prior to the use of t-test analysis, the normality test and homogeneity test were carried out as a prerequisite for conducting the t-test analysis. The normality test is a prerequisite test to find out whether the data used in the study is normally distributed or not so that it can be used to test the hypothesis. The normality testing technique of this study was the Liliefors test. The homogeneity test used in this study was the F-test. The results of the normality and homogeneity tests calculation showed that the data of pre-test and post-test was normally distributed and homogeneous. Results The implementation of mobile learning media for Arabic lesson at Madrasah Aliyah in Lampung, Indonesia shows high effectiveness to improve students’ achievement. It is in agreement with a previous study conducted by Halawani (2008) entitled “Arabic Sign Language Translation System (ArSL-TS) on Mobile Devices”, and its result is: “we proposed the ArSL-TS for the text translating into sign language animations on mobile devices. Since ArSL-TS is intended for mobile deaf users (Arab people), we based it on a standard Arabic sign language and provide animation and instant feedback about the meaning of the arabic text”. Another study entitled “E-learning modules supported by cooperative learning: Impact on Arabic language achievement among Qatar University students” which found out that the overall achievement of university level students improved with the implementation of a cost-free cooperative e-learning approach (Hassan and Fook, 2012). The relevant previous studies indicate that mobile learning instructional model affected positively upon the Arabic lesson achievement. In fact, with proper design mobile learning media may facilitate effective learning as students may find it easy to 1) attain expected competency, 2) explore knowledge and skills, 3) have longer retention of the learning materials, and 4) apply the lesson into practice (Koderi, 2014). Findings This research findings include 1) mobile learning media for Arabic lesson is characterized by the interesting and practical auditory visualization as well as variative questions for assessment; 2) mobile learning everywhere which means that students and teacher may use it anywhere and any time; 3) mobile learning friendly meaning that close relationship between teacher and students appear as they use the media together; 4) students can be concentrated to study by focusing on their personal small smartphonr screen; and 5) process of instruction will run more comfortably as with the use of mobile phone learning may take place more rapidly, and time of learning is adjustable to the activities and times of day. Acknowledgement The study was a collaboration of lecturer and student of Tarbiyah and Teacher Training Faculty at Raden Intan State Islamic University of Lampung Indonesia, and the lecturer of Science & Engineering Faculty at Nusa Cenada University of Kupang Indonesia with a shared fund scheme.

Purpose – International roaming (IR) makes it possible to conveniently use mobile communication services (MCS) such as MI access abroad without switching providers, devices or subscriber identity module (SIM) cards. To increase the intensity of competition in the intra-European Union market for IR services, customers will be enabled to buy IR voice and MI access services separately from their existing domestic MCS, as of July, 2014. Specifically, for separated international MI services providers can choose from three different charge types (use-dependent, flat and combination of flat and use-dependent). The purpose of this paper is to empirically examine customer preferences regarding these tariff types for separated international MI services. Design/methodology/approach – Six research questions concerning antecedents of tariff type preferences for separated international MI access services are derived from a literature review. They are empirically addressed by analyzing survey responses obtained for a sample of 496 German-speaking MCS users. Findings – Customers who actively seek for IR price information, consider IR services to be useful, exhibit high use intensities of MI services, do not restrict their MI usage when travelling abroad and tend to prefer flat rates to other pricing schemes. In contrast to these rather “active users”, customers favoring strictly use-dependent tariff plans exhibit significantly lower IR price information seeking efforts and comparatively low use intensities of MI services. Pricing schemes with MI allowances are especially liked by customers who are well-informed regarding and satisfied with IR prices, report above average use intensities of MI services, restrict their MI use abroad, are more likely to switch providers and use MCS mainly for job-related purposes. Research limitations/implications – The study is based on a German-speaking sample, which deviates from the German adult population. Additionally, the analysis is limited to stated instead of behaviorally revealed preferences for cross-border MI tariff types. Price thresholds influencing whether a cross-border MI tariff is entered into a consumer’s relevant set of offerings are not examined. Practical implications – The research suggests that mobile network operators are well-advised to offer a clearly structured menu of a limited number of tariffs directed to the three profiled customer segments. Notwithstanding the advantages of such a set of rate plans, international MI tariff schemes with a data volume allowance appear to be generally beneficial both from a provider and an end-customer perspective. Originality/value – To date, little is known about customer preferences concerning the three rate plan categories and on antecedents of such preferences in the field of MI access abroad. The present study takes a first step to narrowing this knowledge gap.

India has a population of 1,392,700,250 people and traffic is a big issue. When population and traffic are big issues, it would be wrong to say road accidents are very common in India. Road accidents have now earned India a dubious honour: with nearly 140,000 deaths a year, the country has overtaken China at the top of global road fatalities. India is the only country in the world where more than 15 people are killed and 53 injured every hour due to road accidents. Protego is such a device that can save many lives. Looking at the current scenario accidents and rape are concerned issues excluding corona. Especially in India, the cases are getting more because of the unfinished roads and no proper communication or proper info for the respected departments to help the victims.

Internet of Things (IoT) is a very relevant technology used by internet networks to send and receive sensed data via a sensor. The same relates to common data communication except that sensors and microcontrollers are commonly used in IoT. It is supposed to explore, and there will be developing interest in the IoT framework which gives frequent IoT system capabilities. It connects us to the Internet and also helps us to reveal and manage the actual world by using sharing its info. IoT systems make use of real-world data, so device-collected data may also be a tool for cyber attack. The attack surface also expands as IoT expands and all the vulnerabilities present in the digital world flow through our modern world. DDoS attacks built on compromised IoT systems emerge as a serious problem. There are many technological solutions, but technology has changed a lot, so software solution can be in risk as well. The proposed system will serve as a prevention tool for DDoS attack and send the admin an alert when an attempt is made to hack the IoT device. In this proposed system, intend to provide a highly secured platform that will clean out all the unnecessary data without disrupting IoT’s normal operation.

In the normal course, a teacher can not teach that sometimes does not give the info first. Either directly to the field of teaching, students are appointed as class representative, or attach the previous announcement. Regardless of the reason for the absence of a lecturer during teaching hours, either because of forgetting or any unforeseen events, it is necessary that certain information about the status of lecturers coming, both to the campus or to students in real time. If we notice, communication devices that are the most portable and almost everyone has a cell phone or who is often called by mobile phone. This communication tool we can use to communicate verbally (call) with others, send short messages (SMS), multimedia messaging (MMS), internet access (GPRS), and even capable of streaming video directly (3G). Of some features of the mobile phone, the most frequently used feature is the SMS facility. This may be due to the ease of use and more importantly because of its economic value. Well go from here, in this study will be discussed about the use of SMS technology for the development of a system that can complement the Academic Information System that has been around Keywords: Schedule, Lecturer, SMS

The paper presents the results of some OPNET simulation experiments realized with an aim to benchmark MANET and ZigBee networks’ performances at the seaport environment. The MANET is formed among workers’ and supervisors’ personal digital assistants (PDAs). On the other side, the ZigBee is established between end-nodes or employees’ body central units (BCUs), which collect signals from several active and passive devices embedded into ID badges and personal protective equipment (PPE) pieces; several moving and fixed routers; and the coordinator mounted at the appropriate seaport location. The simulation experiments are realized over the layout of the Port of Bar (Montenegro) container and general cargo terminal by taking into account the real number of workers and supervisors engaged at the terminal per each shift. This research work should give an insight to the seaport’s managers and stakeholders into some advantages and disadvantages of these two considered wireless networks’ schemes, and to motivate them to provide conditions for implementing these or similar on seaport and backend info-communication solutions for uprising the level of occupational safety and overall seaport’s environmental management system.

Like this, examination contributors otherwise the users know how to optimize applicable apparatus or obtain equivalent defensive procedures according to the evaluation results. The smart contracts deployments and function calls within that block get executed on the node that mines the block cloud based IoT ecosystem proposed by many companies. All IoT devices communicate to the cloud and get global state info from the cloud. Blockchain technology integrated with cloud avoids cyber attack on cloud.

Abstract Background Long-acting and permanent contraceptive methods have clear advantages over short-acting methods of contraception that benefit both clients and health systems. Despite this importance, studies show that the proportion of women currently using long acting and permanent contraceptive methods are significantly lower than the proportion using short-acting methods. Objective The main aim of the study was to assess the level of utilization of long acting and permanent contraceptive methods and associated factors among married women in Adama town. Methodology Community Based Cross-Sectional Study was conducted in four kebeles of Adama town from April 15–30, 2015. Multistage sampling technique was used to select the study participants. The collected data was cleaned and entered using Epi info 3.5.3 and analyzed using statistical package for social science version 20.0. Factors associated with utilization of long acting and permanent contraceptive methods were identified using logistic regression model. Result In this study, the magnitude of long acting and permanent contraceptive methods was 20.9%. Implant, Intra-Uterine devices (IUDs) and tubal ligation accounted for 16.1, 4.6, and 0.2% respectively. Current use of long acting and permanent contraceptive methods was higher among women who had high knowledge (AOR = 5.26, 95% CI = 1.90–14.69), positive attitude (AOR = 3.25, 95% CI = 1.60–6.58) and women who had 3–4 children (AOR [95%CI] =2.3[1.14–4.63]) compared to those who had no child. Conclusion Current use of long acting and permanent contraceptive methods in Adama town was low. Level of knowledge, attitude about the methods, and number of children were factors affecting utilization of long acting and permanent contraceptive methods. Targeted Information Education Communication Intervention should be intensified to improve the utilization of these methods.

The project's model is based on the idea that, in the modern world, internet communication has become increasingly crucial. Users can communicate with others quickly and conveniently when using the internet. In light of this, the Android communication software ought to be able to exchange texts, images, and other things more quickly and without any delay at all. One of the platforms that allows developers to create these apps easily is Firebase, which offers period info cloud services. Electronic communication that is instantaneous will be seen as a means of maintaining communication. Compared to other platforms, mechanical man offers a higher platform for developing a wider range of applications for instantaneous electronic communication. This paper's primary goal is to present a package application that will enable operators and users to communicate in real time. With the use of the internet, the system designed for mechanical men can change users' ability to text one another. Every device in the system must be connected to the internet.Social networks are the most common occupation of people. People traveling in different cities or countries have difficulties with communication language; even hotel signs ormenus are in regional languages. Our application is very useful andeasy to use solve such problems. We managed to translate many more languages. Most Indians, especially rural villagers, cannot read or write English; therefore, an efficient interpreter is needed. Translation is necessary to eliminate the communication differences between the two languages and to eliminate the sharing of information between them. Authors need translation to write a rich literary work in one language for others and therefore they need a faster and better translator

Following servers in like way has GSM/GPRS modem that gets vehicle region data by techniques for GSM system and stores info into databases. This info is available to embraced clients of the systems by techniques for sites over the web.

As I sit here, the radio announcer announces a feature on the forthcoming Big Brother series, another chance to engage in this collective shared experience, another opportunity to revel in your very own voyeuristic impulse, what once was private is now made public. Curiously it’s almost fifteen years ago since I released the first Scanner recordings Scanner 1 [1992] and Scanner 2 [1993] featuring the intercepted cellular phone conversations of unsuspecting talkers, which I edited into minimalist musical settings as if they were instruments, bringing into focus issues of privacy and the dichotomy between the public and the private spectrum. Sometimes the high frequency of cellular noise would pervade the atmosphere, at other junctures it would erupt into words and melt down to radio hiss. Intercepted in the data stream, transmissions would blend, blurring the voices and rupturing the light, creating audio transparencies of dreamy, cool ambience. In many ways they pre-empted our reality culture as it exists today. Having the technology to peel open virtually any zone of information and consume the contents, I used the scanner device itself – a modestly sophisticated radio receiver – to explore the relationship between the public and private spheres. Working with sound in this manner suggested a means of mapping the city, in which the scanner device provided an anonymous window into reality, cutting and pasting information to structure an alternative vernacular. It was a rare opportunity to record experience and highlight the threads of desire and interior narrative that we weave into our everyday lives. The sounds of an illicit affair, a liaison with a prostitute, a drug deal or a simple discussion of “what’s for dinner” all exist within an indiscriminate ocean of signals flying overhead, but just beyond our reach. Applying the tools in this manner, I was able to twist state-of-the-art technology in unconventional ways to intercept highly personalised and voyeuristic forms of info food: sound recordings, phone scans, modem and Net intercepts, all of which became material for my multi-layered soundscapes. Every live performance, recording or mix that has followed is still in its way a “true” representation of that moment in time and in that way relates to performance art in the temporality of its data – a “Sound Polaroid” – a way of capturing the moment in sound similar to that of a Polaroid camera, which seizes an image and immediately exposes it to permanence of interception. Is there an innate desire to remain invisible and yet hear the world, scanning it for its stories and secrets? Today for our media saturated culture, this almost fetishistic desire to know all, is expressed in the publishing of private communications, of letters, faxes or telephone conversations, giving rise to all kinds of debate on the nature of privacy and the extent to which its protection can be legislated for. Images come to mind from Wim Wender’s film Wings of Desire where the lead character is a fallen angel left on earth to try and understand the madness of mortal behaviour. At various points he is able to pass through public spaces, the library, an underground train, people’s innermost thoughts and concerns become audible to him while he remains invisible to them. It is here that these Scanner CDs mirror this fantasy of the 20th century: to know everything and to have access to all secrets without being observed. This desire continues to inform our entertainment and cultural channels and looks to continue to do so for some years yet. This listening-in and scanning of the private channels has a clear relationship to surveillance, and connects to an aesthetic explored in works such as the seminal video piece, Der Riese – The Giant (1983) where the artist collaged the contents of surveillance cameras from German supermarkets, subway platforms, traffic crossings and shopping centres, using the tools of commercial voyeurism. Without a director, nor actors nor script, this is a dehumanised exploration of a contemporary history of our post-modern times. Connecting the invisible dots between Vertov’s The Man with a Movie Camera and the Rodney King TV footage, this detached work resonates and celebrates new technology’s ability to film and map everything, scanning our landscape for future reference. We watch with a constant anticipation of resolution, of catching a moment, yet the suspension finally gives way to an exquisite boredom, the true revelation of watching others. The film closes with an alien landscape, unmarked by any human presence, moving over a simulated environment, a toy-town yet still patrolled by the power of surveillance. This corporate datasphere, revealed as a kind of digital fingerprint through its storage and distribution, has moved from security and surveillance to entertainment consumption. For me, zooming in on these spaces in between – between language and understanding, between the digital fallout of ones and zeros, between the redundant and undesired flotsam and jetsam of environmental acoustic space, led to a focus towards the cityscape. Scanning technology led towards an understanding and reading of the environment and city in a fresh manner. If an accent suggested a certain class, age or attitude, then how suggestive was the raw sound around these conversations, how influential was the location where each conversation was held? Sound is ever-present, sometimes as a constantly shifting whir, as a damp grain of footsteps, as the drone-like spangle of distant traffic, as the seemingly motionless air that ripples past our ears, or as the elegant stuttering trill of a bird overhead. How influential was this common envelope of space, the environment in which we consume sound and music? How does one define the spaces between music and sound? When we listen to a Walkman, how do we distinguish between that which is intended – the sound carrier – and that which is incidental: passing traffic, the roar of a plane, the screech of a train door, your own footsteps? Whether active (creator) or passive (listener) we set up a virtual space in which we are each free to explore the sonorous and acoustic strata of what is an intimate yet global expression of space, a simple translation of the social transformations wrought by new technologies. Projects that have followed since then have expanded upon these notions. In 1998 Liverpool became this cityscape of focus, where I produced a project, Stopstarting, which explored the acoustic debris of the city, premiering at the International Symposion on Electronic Art (ISEA) conference in September of that year. For this project I chose significant points of sound located in the city, partly based on random questions in interviewing local people, partly out of self-interest. From these I mapped out a walk that took me from one point to another, minidisc in hand, recording the acoustic data in that place, mapping out the city in sound, teasing out the language that the city speaks. I wanted to create, in a sense, a sound work similar to the opening scene in Robert Altman’s movie Short Cuts (1993), in which a helicopter hovers gently over the densely packed city landscape and the film scans into moments in the daily lives of its inhabitants. It is a motion across a city, an architectural electronic scanning of an almost invisible sound wave. Liverpool, like most cities, has its very own unique sound dialect. Historically one can recall the sound of the docks, the railway station, the Cavern Club where the Beatles played their earliest live shows, their brittle tunes floating through the air of memory. As in Der Riese, voices, traffic lights, announcement speakers, buses, building work, footsteps, telephones and cash machines became the key subjects, the lead players, and were manipulated and transformed into a composition that captured this Sound Polaroid of Liverpool at this particular point in 1998. The following year Surface Noise (1999) which explored the wow and flutter of my own city, London; taking people on a red Routemaster bus journey across the city from Big Ben to St. Paul’s Cathedral, where the sheet music of “London Bridge Is Falling Down” became the score and A-Z for both musical and geographical direction following a Cageian use of indeterminacy. Where each note fell onto the map of the city between these two points not only suggested a location at which to record but also a route that the bus would later follow with the public aboard. Performances followed this routing every night for three nights, at intervals throughout the evening, each re-assembling fragments of the city in terms of sound and image, suggesting the slight shifts in tone and shape in similar places but at very different hours, so that a busy West End street at 18:00 would transform into a ghostly emptiness at 21:00. Surface Noise became a form of alternative film soundtrack, where the film was simply the view through the dusty window of a double-decker bus. Through the brief space of a bus journey the work drew upon many of our common reserves of sonic recognition, mingling the folk memory of the nursery rhyme, the background roar of traffic and the private sounds we make, secure in the knowledge that no one else is listening. Most recently I was commissioned to create a work to celebrate Italian film director Michelangelo Antonioni’s 90th birthday. 52 Space (2002) uses sounds of the city of Rome and elements of his movie The Eclipse (1962) to create a soundtrack of an image of a city suspended in time, anonymous and surreal. The resulting work is a distilled narrative of seductive conversation, musical fragments and scanned city soundscapes. Selecting a series of 52 framed images from the closing moments of the film slowed down to a kind of mnemonic slide show and accompanied by audio culled from the movie, processed with twinkling elements from the soundtrack’s original melody, the live performance conveys a complex and mysterious chronicle, offering up a space for contemplation and reflection as the soundtrack weaves an imaginary narrative. It’s almost as if you are gently floating through the city, experiencing this dream-like state. All of my works have explored the hidden resonances and meanings within memory and, in particular, the subtle traces that people and their actions leave behind. My role has often been to discover and reveal these layers of history, scanning across the mediums, so the works are part urban guide, part urban geography and part detective fiction, raising questions about public and private space. Engaging with the tools of surveillance and scanning technology has given rise to an understanding of communication that was otherwise hidden. Revelation followed from a discovery of the possibilities of these devices. Recording and redirecting these moments back into the public stream has enabled me to construct an archaeology of loss, pathos and missed connections, a momentary forgotten past in our digital future, radioactive fossils of sound, image and the imagination.

Introduction Despite the expansive and multimodal realm of Chinese Boys’ Love (BL) culture (also known as danmei in Chinese), audio works have been notably absent from scholarly discussions, with the focus predominantly being on novels (e.g. Bai; Zhang). This article aims to fill this gap by delving into the transformative impact of sound on narrative engagement within the Chinese BL culture. Focussing on the audio drama adaptations of Grandmaster of Demonic Cultivation (modao zushi, hereafter Grandmaster), originally a serialised Chinese BL novel, this analysis aims to unravel the meticulously crafted BL fantasy in these auditory renditions. The audio drama format delivers an intimate storytelling experience directly to the listener’s ears. Unlike textual media, audio dramas allow listeners to immerse themselves in narratives during various daily activities, deepening their connection with the content. The audio drama Grandmaster, produced by the renowned Chinese platform MissEvan, has garnered a vast fan base and over 640 million plays across three seasons (the episodes and numbers of plays can be found on MissEvan: Season 1, Season 2, and Season 3). Unlike the serialised Web-drama adaption diluted by censorship regulations, the audio drama retains the utmost BL fidelity to the original novel, highlighting the significant potential of this medium in the Chinese BL culture. BL culture has surged in popularity within China, partly due to the export of Japanese culture and the burgeoning Chinese Internet accessibility (Feng). The BL genre encompasses diverse media forms such as novels, fanfiction, comics, animation, and audio/Web dramas, rooted in shared fantasies of romantic love between men. The growing interest in BL culture reflects a response to societal structures like Confucianism and the oppressive education system, which, due to their restrictedness, inadvertently foster the exploration of alternative narratives and identities within the genre (Kwon). While initially inspired by Japanese subculture, Chinese BL has evolved under diverse global influences, including American and other Asian subcultures (Lavin et al.). Chinese BL narratives delve into themes of identity, sexuality, power dynamics, and societal norms, reflecting a rich blend of modern and traditional Chinese culture (Madill and Zhao). Moreover, the rise of BL fandom has empowered female readers to engage in questions about gendered politics, questions that enable them to turn a voyeuristic gaze upon men (Zhang). The versatility of Chinese BL media reflects not only the evolving nature of the genre but also its enduring appeal and cultural significance within contemporary Chinese society. This article initiates a concise review of audio drama in China and the transformative impact of earphone technology, shifting listening experiences from public to intimate settings. It subsequently explores the intricate interplay between Chinese BL novels and audio dramas, elucidating the unique dynamics involved. The analysis then examines specific scenes from Grandmaster, providing insights into its role in facilitating a mesmerising BL audio fantasy. Grandmaster, originating as an Internet novel, has gained a dedicated following. MissEvan, recognising its potential, secured copyrights and commissioned Triones Penguin Studio for a radio drama adaptation in Mandarin. This full-cast dramatisation involves skilled editors, playwrights, and composers, thereby enriching character portrayals and interactions. The professional teamwork and meticulous oversight at each production stage guaranteed regular updates and high audio quality (Shao). Despite the collaborative nature of teamwork, I argue that the power of sound technology personalises the auditory journey as it creates an immersive experience for individual listeners. My analyses mainly rely on research involving actual listeners, along with examinations of specific content within Grandmaster with an idealised listener in consideration, to elucidate the factors contributing to its auditory allure. This examination contributes to a nuanced understanding of Chinese BL culture and its constitutive relationship to audio. From Public Broadcasting to Intimate Voicing: Audio Drama in China Radio broadcasting in China, with roots dating back to the early twentieth century, initially served as a propaganda instrument for mass mobilisation and communication. Chinese storytelling, rooted in acoustics, emphasises the sensory appeal of sound (Chan). It intertwines oral and written traditions in classical literature, particularly fiction and drama (Børdahl). Local vernaculars commonly feature in oral storytelling traditions, whereas Chinese radio programs adopt Mandarin to foster a cohesive national identity via linguistic uniformity. The Communist Party tactically expanded its audience through a radio reception network, establishing a wired broadcasting infrastructure with over 100 million loudspeakers by the 1970s. This revolutionised politics, everyday life, and perceptions of time and space (Li). The interplay between radio and social change reflected China’s pursuit of modernity, as the Communist Party utilised radio to institute a national communication system and monopolise news production. Radio thus served as a crucial tool for constructing and sustaining revolutionary fervor (Lei; He). Radio dramas, often cross-media adaptations from edited films in the 1970s, contributed to everyday sensory pleasure amidst a totalising revolutionary soundscape (Huang). The growth of radio and loudspeaker infrastructure played diverse roles in the revolution, fostering political communication, labour mobilisation, propaganda, surveillance, and even nurturing the Mao cult, turning radio drama into a potent tool for mass mobilisation and communication (Li). As a result, before the widespread availability of televisions in the 1990s, radio structured Chinese people’s daily activities and served as the primary information medium. Technological advancements in earphones, transitioning from larger wired headphones to smaller wireless earbuds like AirPods, have shifted auditory experiences in China from a collective identity tool used in political propaganda to a medium for individualistic entertainment. This change is marked by the personal nature of headphone usage, which can extend social interactions in and beyond physical dimensions (Grusin). The transition from wired headphones to wireless earbuds implements the interiorisation of one person’s body/voice within another, initiating a profound connection that transcends physical limitations (Stankievech). Since 2018, wireless earbuds have exceeded wired headphones in output value in China (Insight and Info), with the online audio market surging to 22 billion yuan in 2021, a 67.9% increase year-on-year. Audiobooks and audio dramas are the most popular genres, with a predominantly female audience under forty who prefer listening at night after work (iimedia). Among audio dramas, BL works generate the most traffic and revenue in China (Y. Wang). Along with such content, putting wireless earbuds inside the ear intensifies the intimacy of listening, transmitting voices directly into the listener’s head and sitting alongside their thoughts (Weldon). This physical closeness underscores the exclusive bond between the listener and the audio content, redefining oral narratives and transforming public and political audio content into a more personal and intimate medium. The use of wireless earbuds even extends listening beyond mere auditory experience, empowering haptic sensations that create an intimate bond. The acousmatic voice envelops the listener’s ears, establishing a connection even before the message’s content is considered (Madsen and Potts). The ear’s sensitivity prompts consciousness and memory, unlocking the imaginative world (C. Wang 91-94). This sensory engagement surpasses traditional auditory limits, resembling a physical encounter where listeners feel like their body has joined with the body of sound. Dermot Rattigan, discussing radio drama, notes how listeners fill the void with mental visualisations and imagination, entering a state of individual ‘virtual reality’ through aural stimulation (Rattigan 118). Drawing from visual psychology, Shaffer likens the soundscape to a dynamic landscape painting, emphasising the fluidity of auditory experiences (Schafer). Listening becomes a multi-dimensional journey involving the entire body and mind, a compelling tool for reception and connection that transcends reality’s boundaries. The advent of MP3 technologies and the podcasting boom also extends the former spatial and temporal limitations of listening. In contrast to traditional real-time broadcasting, MP3 technologies enable voices to persist indefinitely into the future (Madsen and Potts). This temporal flexibility further builds a private sound sphere for listeners (Euritt). Listeners no longer need to share time and space with others around loudspeakers or radios, so they can freely indulge in their subcultural preferences, such as BL stories, without concern for societal judgment. Many listeners strategically incorporate audio dramas into their daily schedule, choosing moments of solitude such as before sleep or upon waking, where they can detach from the expectations of their physical space and identity roles. This is particularly evident among devoted fans of Chinese BL audio dramas, who carve out personal time for these works and seek a quiet space for focussed engagement (Wang 55). This intentional, focussed engagement differs from the typical mode of everyday radio listening as it serves an expanded, widespread dissemination environment that is also highly intimate (Madsen and Potts). Thus, the convergence of temporal flexibility and immersive technology shapes listener engagement and interaction dynamics. The fusion of intimacy, physical closeness, and temporal flexibility heightens the allure of the voice in programs with erotic undertones, such as BL audio dramas. Euritt introduces the concept of ‘breathing out into you’ to explain queer eroticism in podcasts, emphasising shared breaths and potential haptic exchanges that enhance the sensual dimensions of sound (Euritt 27-53). This wireless, intimately riveting auditory experience transforms the soundscape and reshapes contemporary social interactions. This shift is particularly noteworthy for popular Chinese radio and audio content as they began as a public, propaganda-oriented tool and transitioned into forms as novel as the intimate domain of BL audio dramas. This change underscores the transformative power of sound in shaping interactions, surpassing conventional storytelling boundaries, and ushering in a new era of engaging narratives. The 2.5-Dimensional: Auralising Chinese Boys’ Love Fiction The BL genre emerges as a cultural and social force that can potentially challenge traditional Chinese values. Its focus on male-male love inherently questions societal expectations around gender and sexuality in ways that disrupt Confucian ideology’s emphasis on heterosexual marriage and lineage (Welker). Furthermore, the genre’s similarity to the melodramatic ‘soap opera’ storytelling style resonates with Western ideals of individualism and aligns more with a feminist viewpoint that contrasts with the male-dominant heterosexism often found in traditional Chinese narratives (Mumford). This emphasis on individual desires also implicitly disputes the collectivist and socialist values, as well as the importance of the extended family, traditionally embraced in Chinese cultures. In short, the love, sex, and romance depicted in BL represent a departure from traditional Chinese values, positioning the BL genre as a vehicle for cultural exchange and societal transformation in terms of gender norms. The surge of Internet radio and social media in the 2010s has substantially contributed to the professionalisation and commercialisation of Chinese BL audio dramas. MissEvan, a prominent barrage-audio and live-broadcasting Website, has been crucial to this proliferation (Hu et al.). Before the advent of commercial dubbing, enthusiasts of BL novels voluntarily recorded non-profit Chinese audio dramas and disseminated them online. The popularity of BL novels subsequently prompted their adaptation into animation and television dramas, creating a demand for dubbing services. This demand inaugurated a niche for professional voice actors to hone and showcase their skills. The integration of technology and capital by commercial production teams has markedly elevated the quality of Chinese BL audio dramas. Amidst tightening censorship in 2021, Chinese BL online novels and their television/Web-drama adaptations faced restrictions. Audio drama emerged as a less restrictive medium, which can relatively directly present explicit gay relationships (Hu et al.). Listeners of Chinese BL audio dramas typically read the online novel beforehand, engaging in dual consumption for pleasure in both reading and listening (Wang 58). Their engagement transcends plot comprehension, focussing instead on appreciating sophisticated voice performances. Exploring how audio dramas derived from novels can transcend textual narratives and captivate audiences has become a central focus in the production process, highlighting the flourishing landscape of audio drama. The listening process provides informed listeners with a re-experience, offering multiple sensory and emotional pleasures by translating words into voice and sounds. Unlike film and television dubbing, which requires synchronisation with actors’ lip movements and speech rhythms, dubbing for animation, audio dramas, and games gives greater creative autonomy to voice actors. The thriving market for audio dramas has shaped the Chinese dubbing industry, cultivating a devoted fan base for previously overlooked voice actors. The character voices (CVs, also known as voice actors, or VAs) have emerged as central figures, attracting fans and driving media traffic. In the late 2010s, collaborations between MissEvan and renowned CVs resulted in the adaptation of popular online fiction into paid audio dramas, exemplified by Grandmaster, which aired in 2017 and 2018 (Hu et al.). Fans’ motivation for engaging with BL audio dramas extends beyond intertextual and trans-media entertainment but incorporates an appreciation for their beloved CVs, thereby fostering a culture of support within the burgeoning Chinese BL audio drama market. In the storytelling of aural media, CVs are crucial in bridging the auditor’s BL imagination between the text and the characters as their performances breathe life into characters. CVs fill a gap between two-dimensional works (fiction, comic, and animation) and the three-dimensional real world, forging ‘2.5-dimensional’ content. This term originated in the 1970s-80s to describe anime voice actors, who imbue two-dimensional characters with a sense of existence and generate interrelations between the real, fictional, and cyber worlds (Sugawa-Shimada and Annett). In BL audio dramas, CVs commonly stimulate listeners’ sensations through male moans that facilitate an erotic flow between sound and body, arousing desire through the auditory channel. The incorporation of scenes with sexual innuendo between the male protagonists creates a space for listeners to indulge in these moments with earphones on, enveloped in their own private, eroticised sphere of engagement between fiction and reality. The deliberate pauses, gasps, and panting become the silent dialogue that intertwines inner voices with external narratives, enhancing comprehensive sensory engagement for listeners. Audio Fantasy in Grandmaster of Demonic Cultivation Grandmaster is a seminal Chinese BL novel that blends martial arts, supernatural fantasies, and emotional depth. Set in a richly imagined world where immortal cultivation techniques bestow individuals with extraordinary powers, the story follows protagonists Wei Wuxian’s and Lan Wangji’s intertwined fates. Its captivating narrative and nuanced characters have garnered a global fanbase, solidifying its place as a cornerstone of Chinese BL literature and media. The audio drama Grandmaster faithfully mirrors the novel’s narrative structure, unfolding from the protagonist Wei’s perspective after his reincarnation, weaving memories of his past and present life, including his romantic involvement with Lan. Wei’s establishment of the forbidden Demonic Path leads to his death, but he is reincarnated thirteen years later and reunites with Lan. After his reincarnation, Wei gradually realises Lan’s concealed profound affection and scarification for him. Diverging from the television/Web-drama adaptation, which replaces the romance with platonic ‘bromance’ due to censorship (Lei), the audio drama accentuates the impassioned soundscapes of their relationship. The three-season series, comprising episodes of 30-40 minutes, offers the first three episodes for free, with subsequent content requiring payment (approximately four to six dollars per season). Impressively, the series has driven earnings exceeding $1.5 million (Asia Business Leaders). This success highlights the captivating and profitable potential of audio dramas as a BL storytelling medium. Unlike the original novel, which uses an omniscient narrator, the audio drama advances the plot solely through character dialogue. Consequently, listeners navigate the storyline guided by the rhythm of the CVs’ delivery and the accompanying music. Different from Japanese BL audio dramas that feature as ‘voice porn’ for women (Ishida), Grandmaster subtly implies the romance between Lan and Wei, with the most intimate interactions limited to kisses. Rather than sexually explicit content, the drama focusses on the characters’ affective fulfillment after a prolonged thirteen-year anticipation. For instance, in Season 1, Episode 4, Wei attempts to hide his identity and flee from Lan. When Wei creeps back towards Lan’s bed to steal the pass for exiting Lan’s residence, Lan catches him. Rather than simply saying ‘Get off’ as in the novel, Lan instructs Wei in the audio drama to ‘Get off from my body,’ offering listeners additional physical contact cues (the quotes from the novel and audio drama in this article are translations from Chinese to English). Following Wei’s intentional refusal, the CV Wei Chao, portraying Lan, strategically breathes before his next line, ‘then stay like this for the whole night’. The breath conveys Lan’s deep, restrained affection and evokes the listener’s nuanced emotional resonance. To represent Lan’s affection within his minimal and often monosyllabic lines requires the CV to convey emotions through breaths and intonations, which commonly elicit an autonomous sensory meridian response (ASMR) in listeners. ASMR is a tingling sensation often triggered by soft low-tone spoken or whispered voices (Barratt and Davis). Wei Chao intentionally lowers his voice to interpret how Lan’s sighs encapsulate unspoken sentiments (Wei). In contrast, the CV Lu Zhixing employs a playful and sweet tone in his portrayal of Wei Wuxian. When Lu delivers flirtatious lines, online real-time comments frequently express listeners’ admiration, suggesting that his voice is even more captivating than women’s. The contrasting restraint and playfulness intensify the listener’s empathy for Lan’s unspeakable passion. Thus, Lan’s subtle expressions of his restrained love become the primary attraction for listeners (KikuHonda). The high-quality sound further amplifies the breath sounds, making each of Lan’s ‘hmm’ responses—indifferent, melancholy, or indulgent—a nuanced emotional trigger. Listeners, through their wireless earbuds, engage in the meticulously crafted expressions of Lan within a profoundly personal soundscape. This listening mode is a crucial component of the overall enthralling auditory voyage, augmenting the appreciation of the characters’ subdued emotions. The layered integration of music and sound in Grandmaster constructs a three-dimensional sonic storytelling landscape. Effective soundscapes for storytelling are crafted by multiple dimensions: sound source, temporal progression, simultaneous layers, and spatialisation. Sound editing allows for source selection, with listeners experiencing these dimensions as integrated, not separate or sequential (Stedman et al.). The audio drama Grandmaster distinguishes itself from the novel by using voice flashbacks for narrative enhancement. In Season Three, Episode 12, when Lan’s brother recounts Lan’s sacrifice for Wei, particularly the moment when Lan endured severe punishment to save Wei thirteen years ago, the soundscape instantly transports listeners to that intense scene. Listeners vividly hear the swishing force of the whip and its impact, immersing them in the sounds of Lan’s anguish and unwavering love. This direct auditory impact allows listeners to feel as if they are experiencing the events firsthand, physically sensing the hardships encountered by the protagonists in understanding each other’s affection, intensifying their hard-won love. The musical orchestration and vocal interplay are also pivotal to conveying the story. In the storyline, Wei and Lan showcase proficiency in their respective instruments: Wei with the flute and Lan with the guqin (a seven-string Chinese zither). The tonal features of these instruments—the flute’s melodious brightness and the guqin’s deep lingering resonance—symbolise the protagonists’ distinct personalities, adding ingenious layers to their relationship. In the Guanyin Temple scene (Season Three, Episode 13), as Wei confesses to Lan, the initial background music features the flute, guqin, and rain sounds, foreshadowing the confessional moment with Wei’s worries that Lan will not believe his words. As Wei promises to remember Lan’s every word from now on, the music incorporates the guzheng, a Chinese string instrument with a brighter timbre than guqin. The tremolo technique of guzheng is reminiscent of the characters’ heartstring vibrations. Through auditory cues, the narrative climaxes with Wei’s heartfelt confession of love for Lan. When Wei straightforwardly confesses, ‘I fancy you, I love you, I want you, I cannot leave you. … I do not want anyone but you—it cannot be anyone but you’ (Season Three, Episode 13), his heartfelt words are accompanied by layered sounds, including the duet of the flute and guqin, and the sound of thunder and rain, accelerating the affective climax. Lan echoes Wei’s words, underscored by erhu, thereby showing how this string instrument resembles humans’ sobbing voices through its sliding technique, rendering the touching melody. The heartbeat and rain sound with Lan’s panting highlight the painful loneliness of Lan’s thirteen-year wait. The intricate fusion of musical and vocal elements enables listeners to not only hear but also to feel the mutual affection between the characters, culminating in a sense of delight upon the disclosure of their reciprocal love following numerous adventures. Using earbuds amplifies listeners’ capacity to fully receive auditory details and stereo effects, thereby contributing to the popularity of BL audio dramas that skillfully convey unspoken love through detailed soundscapes. Epilogue The Grandmaster audio dramas provide crafted episodes that fulfill fans’ passionate needs that exceed the novel’s scope. In addition to adapting the novel, the team has conceived original mini-dramas that enrich the character images. Listeners can access additional content such as iconic quotes, ringtones, and ‘lullaby’ episodes recorded by the leading CVs, maximising the captivating power of sound and justifying listeners’ investment. The multi-layered use of sounds and instrumental arrangements effectively constructs a three-dimensional soundscape, reinforcing the audience’s understanding of the story and characters. Unlike television/Web-drama adaptations, the audio drama fully amplifies the tragic elements of the novel, pushing the immersed listener’s imagination past textual limitations. While casting choices and modelling in visual adaptions may disappoint viewers’ expectations at times, the audio drama leverages the power of sound to stimulate listeners’ imaginations, encouraging them to visualise their own specific character images. Skillful orchestration, along with sound effects, breaths, and dialogues in Grandmaster intensifies emotional expression, forming a rich and dimensional soundscape and unlocking new possibilities for audio drama artistic expression for Chinese BL fantasy.

It seems nowadays that any aspect of collecting and displaying tangible or intangible material culture is labeled as curating: shopkeepers curate their wares; DJs curate their musical selections; magazine editors curate media stories; and hipsters curate their coffee tables. Given the increasing ubiquity and complexity of 21st-century notions of curatorship, the current issue of MC Journal, ‘curate’, provides an excellent opportunity to consider some of the changes that have occurred in professional practice since the emergence of the ‘digital turn’. There is no doubt that the internet and interactive media have transformed the way we live our daily lives—and for many cultural commentators it only makes sense that they should also transform our cultural experiences. In this paper, I want to examine the issue of curatorial practice in the postdigital age, looking some of the ways that curating has changed over the last twenty years—and some of the ways it has not. The term postdigital comes from the work of Ross Parry, and is used to references the ‘tipping point’ where the use of digital technologies became normative practice in museums (24). Overall, I contend that although new technologies have substantially facilitated the way that curators do their jobs, core business and values have not changed as the result of the digital turn. While, major paradigm shifts have occurred in the field of professional curatorship over the last twenty years, these shifts have been issue-driven rather than a result of new technologies. Everyone’s a Curator In a 2009 article in the New York Times, journalist Alex Williams commented on the growing trend in American consumer culture of labeling oneself a curator. “The word ‘curate’,’’ he observed, “has become a fashionable code word among the aesthetically minded, who seem to paste it onto any activity that involves culling and selecting” (1). Williams dated the origins of the popular adoption of the term ‘curating’ to a decade earlier; noting the strong association between the uptake and the rise of the internet (2). This association is not surprising. The development of increasingly interactive software such as Web 2.0 has led to a rapid rise in new technologies aimed at connecting people and information in ways that were previously unimaginable. In particular the internet has become a space in which people can collect, store and most importantly share vast quantities of information. This information is often about objects. According to sociologist Jyri Engeström, the most successful social network sites on the internet (such as Pinterest, Flickr, Houzz etc), use discrete objects, rather than educational content or interpersonal relationships, as the basis for social interaction. So objects become the node for inter-personal communication. In these and other sites, internet users can find, collate and display multiple images of objects on the same page, which can in turn be connected at the press of a button to other related sources of information in the form of text, commentary or more images. These sites are often seen as the opportunity to virtually curate mini-exhibitions, as well as to create mood boards or sites of virtual consumption. The idea of curating as selective aesthetic editing is also popular in online markets places such as Etsy where numerous sellers offer ‘curated’ selections from home wares, to prints, to (my personal favorite) a curated selection of cat toys. In all of these exercises there is an emphasis on the idea of connoisseurship. As part of his article on the new breed of ‘curators’, for example, Alex Williams interviewed Tom Kalendrain, the Fashion Director of a leading American department store, which had engaged in a collaboration with Scott Schuman of the fashion blog, the Sartorialist. According to Kalendrain the store had asked Schuman to ‘curate’ a collection of clothes for them to sell. He justified calling Schuman a curator by explaining: “It was precisely his eye that made the store want to work with him; it was about the right shade of blue, about the cut, about the width of a lapel” (cited in Williams 2). The interview reveals much about current popular notions of what it means to be a curator. The central emphasis of Kalendrain’s distinction was on connoisseurship: exerting a privileged authoritative voice based on intimate knowledge of the subject matter and the ability to discern the very best examples from a plethora of choices. Ironically, in terms of contemporary museum practice, this is a model of curating that museums have consciously been trying to move away from for at least the last three decades. We are now witnessing an interesting disconnect in which the extra-museum community (represented in particular by a postdigital generation of cultural bloggers, commentators and entrepreneurs) are re-vivifying an archaic model of curating, based on object-centric connoisseurship, just at the point where professional curators had thought they had successfully moved on. From Being about Something to Being for Somebody The rejection of the object-expert model of curating has been so persuasive that it has transformed the way museums conduct core business across all sectors of the institution. Over the last thirty to forty years museums have witnessed a major pedagogical shift in how curators approach their work and how museums conceptualise their core values. These paradigmatic and pedagogical shifts were best characterised by the museologist Stephen Weil in his seminal article “From being about something to being for somebody.” Weil, writing in the late 1990s, noted that museums had turned away from traditional models in which individual curators (by way of scholarship and connoisseurship) dictated how the rest of the world (the audience) apprehended and understood significant objects of art, science and history—towards an audience centered approach where curators worked collaboratively with a variety of interested communities to create a pluralist forum for social change. In museum parlance these changes are referred to under the general rubric of the ‘new museology’: a paradigm shift, which had its origins in the 1970s; its gestation in the 1980s; and began to substantially manifest by the 1990s. Although no longer ‘new’, these shifts continue to influence museum practices in the 2000s. In her article, “Curatorship as Social Practice’” museologist Christina Kreps outlined some of the developments over recent decades that have challenged the object-centric model. According to Kreps, the ‘new museology’ was a paradigm shift that emerged from a widespread dissatisfaction with conventional interpretations of the museum and its functions and sought to re-orient itself away from strongly method and technique driven object-focused approaches. “The ‘new museum’ was to be people-centered, action-oriented, and devoted to social change and development” (315). An integral contributor to the developing new museology was the subjection of the western museum in the 1980s and ‘90s to representational critique from academics and activists. Such a critique entailed, in the words of Sharon Macdonald, questioning and drawing attention to “how meanings come to be inscribed and by whom, and how some come to be regarded as ‘right’ or taken as given” (3). Macdonald notes that postcolonial and feminist academics were especially engaged in this critique and the growing “identity politics” of the era. A growing engagement with the concept that museological /curatorial work is what Kreps (2003b) calls a ‘social process’, a recognition that; “people’s relationships to objects are primarily social and cultural ones” (154). This shift has particularly impacted on the practice of museum curatorship. By way of illustration we can compare two scholarly definitions of what constitutes a curator; one written in 1984 and one from 2001. The Manual of Curatorship, written in 1994 by Gary Edson and David Dean define a curator as: “a staff member or consultant who is as specialist in a particular field on study and who provides information, does research and oversees the maintenance, use, and enhancement of collections” (290). Cash Cash writing in 2001 defines curatorship instead as “a social practice predicated on the principle of a fixed relation between material objects and the human environment” (140). The shift has been towards increased self-reflexivity and a focus on greater plurality–acknowledging the needs of their diverse audiences and community stakeholders. As part of this internal reflection the role of curator has shifted from sole authority to cultural mediator—from connoisseur to community facilitator as a conduit for greater community-based conversation and audience engagement resulting in new interpretations of what museums are, and what their purpose is. This shift—away from objects and towards audiences—has been so great that it has led some scholars to question the need for museums to have standing collections at all. Do Museums Need Objects? In his provocatively titled work Do Museums Still Need Objects? Historian Steven Conn observes that many contemporary museums are turning away from the authority of the object and towards mass entertainment (1). Conn notes that there has been an increasing retreat from object-based research in the fields of art; science and ethnography; that less object-based research seems to be occurring in museums and fewer objects are being put on display (2). The success of science centers with no standing collections, the reduction in the number of objects put on display in modern museums (23); the increasing phalanx of ‘starchitect’ designed museums where the building is more important than the objects in it (11), and the increase of virtual museums and collections online, all seems to indicate that conventional museum objects have had their day (1-2). Or have they? At the same time that all of the above is occurring, ongoing research suggests that in the digital age, more than ever, people are seeking the authenticity of the real. For example, a 2008 survey of 5,000 visitors to living history sites in the USA, found that those surveyed expressed a strong desire to commune with historically authentic objects: respondents felt that their lives had become so crazy, so complicated, so unreal that they were seeking something real and authentic in their lives by visiting these museums. (Wilkening and Donnis 1) A subsequent research survey aimed specifically at young audiences (in their early twenties) reported that: seeing stuff online only made them want to see the real objects in person even more, [and that] they felt that museums were inherently authentic, largely because they have authentic objects that are unique and wonderful. (Wilkening 2) Adding to the question ‘do museums need objects?’, Rainey Tisdale argues that in the current digital age we need real museum objects more than ever. “Many museum professionals,” she reports “have come to believe that the increase in digital versions of objects actually enhances the value of in-person encounters with tangible, real things” (20). Museums still need objects. Indeed, in any kind of corporate planning, one of the first thing business managers look for in a company is what is unique about it. What can it provide that the competition can’t? Despite the popularity of all sorts of info-tainments, the one thing that museums have (and other institutions don’t) is significant collections. Collections are a museum’s niche resource – in business speak they are the asset that gives them the advantage over their competitors. Despite the increasing importance of technology in delivering information, including collections online, there is still overwhelming evidence to suggest that we should not be too quick to dismiss the traditional preserve of museums – the numinous object. And in fact, this is precisely the final argument that Steven Conn reaches in his above-mentioned publication. Curating in the Postdigital Age While it is reassuring (but not particularly surprising) that generations Y and Z can still differentiate between virtual and real objects, this doesn’t mean that museum curators can bury their heads in the collection room hoping that the digital age will simply go away. The reality is that while digitally savvy audiences continue to feel the need to see and commune with authentic materially-present objects, the ways in which they access information about these objects (prior to, during, and after a museum visit) has changed substantially due to technological advances. In turn, the ways in which curators research and present these objects – and stories about them – has also changed. So what are some of the changes that have occurred in museum operations and visitor behavior due to technological advances over the last twenty years? The most obvious technological advances over the last twenty years have actually been in data management. Since the 1990s a number of specialist data management systems have been developed for use in the museum sector. In theory at least, a curator can now access the entire collections of an institution without leaving their desk. Moreover, the same database that tells the curator how many objects the institution holds from the Torres Strait Islands, can also tell her what they look like (through high quality images); which objects were exhibited in past exhibitions; what their prior labels were; what in-house research has been conducted on them; what the conservation requirements are; where they are stored; and who to contact for copyright clearance for display—to name just a few functions. In addition a curator can get on the internet to search the online collection databases from other museums to find what objects they have from the Torres Strait Islands. Thus, while our curator is at this point conducting the same type of exhibition research that she would have done twenty years ago, the ease in which she can access information is substantially greater. The major difference of course is that today, rather than in the past, the curator would be collaborating with members of the original source community to undertake this project. Despite the rise of the internet, this type of liaison still usually occurs face to face. The development of accessible digital databases through the Internet and capacity to download images and information at a rapid rate has also changed the way non-museum staff can access collections. Audiences can now visit museum websites through which they can easily access information about current and past exhibitions, public programs, and online collections. In many cases visitors can also contribute to general discussion forums and collections provenance data through various means such as ‘tagging’; commenting on blogs; message boards; and virtual ‘talk back’ walls. Again, however, this represents a change in how visitors access museums but not a fundamental shift in what they can access. In the past, museum visitors were still encouraged to access and comment upon the collections; it’s just that doing so took a lot more time and effort. The rise of interactivity and the internet—in particular through Web 2.0—has led many commentators to call for a radical change in the ways museums operate. Museum analyst Lynda Kelly (2009) has commented on the issue that: the demands of the ‘information age’ have raised new questions for museums. It has been argued that museums need to move from being suppliers of information to providing usable knowledge and tools for visitors to explore their own ideas and reach their own conclusions because of increasing access to technologies, such as the internet. Gordon Freedman for example argues that internet technologies such as computers, the World Wide Web, mobile phones and email “… have put the power of communication, information gathering, and analysis in the hands of the individuals of the world” (299). Freedman argued that museums need to “evolve into a new kind of beast” (300) in order to keep up with the changes opening up to the possibility of audiences becoming mediators of information and knowledge. Although we often hear about the possibilities of new technologies in opening up the possibilities of multiple authors for exhibitions, I have yet to hear of an example of this successfully taking place. This doesn’t mean, however, that it will never happen. At present most museums seem to be merely dipping their toes in the waters. A recent example from the Art Gallery of South Australia illustrates this point. In 2013, the Gallery mounted an exhibition that was, in theory at least, curated by the public. Labeled as “the ultimate people’s choice exhibition” the project was hosted in conjunction with ABC Radio Adelaide. The public was encouraged to go online to the gallery website and select from a range of artworks in different categories by voting for their favorites. The ‘winning’ works were to form the basis of the exhibition. While the media spin on the exhibition gave the illusion of a mass curated show, in reality very little actual control was given over to the audience-curators. The public was presented a range of artworks, which had already been pre-selected from the standing collections; the themes for the exhibition had also already been determined as they informed the 120 artworks that were offered up for voting. Thus, in the end the pre-selection of objects and themes, as well as the timing and execution of the exhibition remained entirely in the hand of the professional curators. Another recent innovation did not attempt to harness public authorship, but rather enhanced individual visitor connections to museum collections by harnessing new GPS technologies. The Streetmuseum was a free app program created by the Museum of London to bring geotagged historical street views to hand held or portable mobile devices. The program allowed user to undertake a self-guided tour of London. After programing in their route, users could then point their device at various significant sites along the way. Looking through their viewfinder they would see a 3D historic photograph overlayed on the live site – allowing user not only to see what the area looked like in the past but also to capture an image of the overlay. While many of the available tagging apps simply allow for the opportunity of adding more white noise, allowing viewers to add commentary, pics, links to a particular geo tagged site but with no particular focus, the Streetmuseum had a well-defined purpose to encourage their audience to get out and explore London; to share their archival photograph collection with a broader audience; and to teach people more about London’s unique history. A Second Golden Age? A few years ago the Steven Conn suggested that museums are experiencing an international ‘golden age’ with more museums being built and visited and talked about than ever before (1). In the United States, where Conn is based, there are more than 17,500 accredited museums, and more than two million people visit some sort of museum per day, averaging around 865 million museum visits per year (2). However, at the same time that museums are proliferating, the traditional areas of academic research and theory that feed into museums such as history, cultural studies, anthropology and art history are experiencing a period of intense self reflexivity. Conn writes: At the turn of the twenty-first century, more people are going to more museums than at any time in the past, and simultaneously more scholars, critics, and others are writing and talking about museums. The two phenomena are most certainly related but it does not seem to be a happy relationship. Even as museums enjoy more and more success…many who write about them express varying degrees of foreboding. (1) There is no doubt that the internet and increasingly interactive media has transformed the way we live our daily lives—it only makes sense that it should also transform our cultural experiences. At the same time Museums need to learn to ride the wave without getting dumped into it. The best new media acts as a bridge—connecting people to places and ideas—allowing them to learn more about museum objects and historical spaces, value-adding to museum visits rather than replacing them altogether. As museologust Elaine Gurian, has recently concluded, the core business of museums seems unchanged thus far by the adoption of internet based technology: “the museum field generally, its curators, and those academic departments focused on training curators remain at the core philosophically unchanged despite their new websites and shiny new technological reference centres” (97). Virtual life has not replaced real life and online collections and exhibitions have not replaced real life visitations. Visitors want access to credible information about museum objects and museum exhibitions, they are not looking for Wiki-Museums. Or if they are are, they are looking to the Internet community to provide that service rather than the employees of state and federally funded museums. Both provide legitimate services, but they don’t necessarily need to provide the same service. In the same vein, extra-museum ‘curating’ of object and ideas through social media sites such as Pinterest, Flikr, Instagram and Tumblr provide a valuable source of inspiration and a highly enjoyable form of virtual consumption. But the popular uptake of the term ‘curating’ remains as easily separable from professional practice as the prior uptake of the terms ‘doctor’ and ‘architect’. An individual who doctors an image, or is the architect of their destiny, is still not going to operate on a patient nor construct a building. While major ontological shifts have occurred within museum curatorship over the last thirty years, these changes have resulted from wider social shifts, not directly from technology. This is not to say that technology will not change the museum’s ‘way of being’ in my professional lifetime—it’s just to say it hasn’t happened yet.

This paper will compare the metaphoric structuring of the ecological concept of resilience—with its roots in Holling's 1973 paper; with psychological concepts of resilience which followed from research—such as Werner, Bierman, and French and Garmezy and Streitman) published in the early 1970s. This metaphoric analysis will expose the difference between complex adaptive systems models of resilience in ecology and studies related to resilience in relation to climate change; compared with the individualism of linear equilibrium models of resilience which have dominated discussions of resilience in psychology and economics. By examining the ontological commitments of these competing metaphors, I will show that the individualistic concept of resilience which dominates psychological discussions of resilience is incompatible with the ontological commitments of ecological concepts of resilience. Because the ontological commitments of the concepts of ecological resilience on the one hand, and psychological resilience on the other, are so at odds with one another, it is important to be clear which concept of resilience is being evaluated for its adequacy as a concept. Having clearly distinguished these competing metaphors and their ontological commitments, this paper will show that it is the complex adaptive systems model of resilience from ecology, not the individualist concept of psychological resilience, that has been utilised by both the academic discussions of adaptation to climate change, and the operationalisation of the concept of resilience by social movements like the permaculture, ecovillage, and Transition Towns movements. Ontological Metaphors My analysis of ontological metaphors draws on insights from Kuhn's (114) account of gestalt perception in scientific paradigm shifts; the centrality of the role of concrete analogies in scientific reasoning (Masterman 77); and the theorisation of ontological metaphors in cognitive linguistics (Gärdenfors). Figure 1: Object Ontological commitments reflect the shared beliefs within a community about the sorts of things that exist. Our beliefs about what exists are shaped by our sensory and motor interactions with objects in the physical world. Physical objects have boundaries and surfaces that separate the object from not-the-object. Objects have insides and outsides, and can be described in terms of more-or-less fixed and stable “objective” properties. A prototypical example of an “object” is a “container”, like the example shown in Figure 1. Ontological metaphors allow us to conceive of “things” which are not objects as if they were objects by picking “out parts of our experience and treat them as [if they were] discrete entities or substances of a uniform kind” (Lakoff and Johnson 25). We use ontological metaphors when we imagine a boundary around a collection of things, such as the members of a team or trees in a forest, and conceive of them as being in a container (Langacker 191–97). We can then think of “things” like a team or forest as if they were a single entity. We can also understand processes and activities as if they were things with boundaries. Whether or not we characterise some aspect of our experience as a noun (a bounded entity) or as a verb (a process that occurs over time) is not determined by the nature of things in themselves, but by our understanding and interpretation of our experience (Langacker 233). In this paper I employ a technique that involves examining the details of “concrete images” from the source domains for metaphors employed in the social sciences to expose for analysis their ontological commitments (Harrison, “Politics” 215; Harrison, “Economics” 7). By examining the ontological metaphors that structure the resilience literature I will show how different conceptions of resilience reflect different beliefs and commitments about the sorts of “things” there are in the world, and hence how we can study and understand these “things.” Engineering Metaphors In his discussion of engineering resilience, Holling (“Engineering Vs. Ecological” 33) argues that this conception is the “foundation for economic theory”, and defined in terms of “resistance to disturbance and the speed of return to the equilibrium” or steady state of the system. Whereas Holling takes his original example of the use of the engineering concept of resilience from economics, Pendall, Foster, & Cowell (72), and Martin-Breen and Anderies (6) identify it as the concept of resilience that dominates the field of psychology. They take the stress loading of bridges to be the engineering source for the metaphor. Figure 2: Pogo stick animation (Source: Blacklemon 67, CC http://en.wikipedia.org/wiki/File:Pogoanim.gif). In order to understand this metaphor, we need to examine the characteristics of the source domain for the metaphor. A bridge can be “under tension, compression or both forces at the same time [and] experiences what engineers define as stress” (Matthews 3). In order to resist these forces, bridges need to be constructed of material which “behave much like a spring” that “strains elastically (deforms temporarily and returns to its original shape after a load has been removed) under a given stress” (Gordon 52; cited in Matthews). The pogostick shown in Figure 2 illustrates how a spring returns to its original size and configuration once the load or stress is removed. WGBH Educational Foundation provides links to simple diagrams that illustrate the different stresses the three main designs of bridges are subject to, and if you compare Computers & Engineering's with Gibbs and Bourne's harmonic spring animation you can see how both a bridge under live load and the pogostick in Figure 2 oscillate just like an harmonic spring. Subject to the elastic limits of the material, the deformation of a spring is proportional to the stress or load applied. According to the “modern theory of elasticity [...] it [is] possible to deduce the relation between strain and stress for complex objects in terms of intrinsic properties of the materials it is made of” (“Hooke’s Law”). When psychological resilience is characterised in terms of “properties of individuals [that] are identified in isolation” (Martin-Breen and Anderies 12); and in terms of “behaviours and attributes [of individuals] that allow people to get along with one another and to succeed socially” (Pendall, Foster, and Cowell 72), they are reflecting this engineering focus on the properties of materials. Martin-Breen and Anderies (42) argue that “the Engineering Resilience framework” has been informed by ontological metaphors which treat “an ecosystem, person, city, government, bridge, [or] society” as if it were an object—“a unified whole”. Because this concept of resilience treats individuals as “objects,” it leads researchers to look for the properties or characteristics of the “materials” which individuals are “made of”, which are either elastic and allow them to “bounce” or “spring” back after stress; or are fragile and brittle and break under load. Similarly, the Designers Institute (DINZ), in its conference on “Our brittle society,” shows it is following the engineering resilience approach when it conceives of a city or society as an object which is made of materials which are either “strong and flexible” or “brittle and fragile”. While Holling characterises economic theory in terms of this engineering metaphor, it is in fact chemistry and the kinetic theory of gases that provides the source domain for the ontological metaphor which structures both static and dynamic equilibrium models within neo-classical economics (Smith and Foley; Mirowski). However, while springs are usually made out of metals, they can be made out of any “material [that] has the required combination of rigidity and elasticity,” such as plastic, and even wood (in a bow) (“Spring (device)”). Gas under pressure turns out to behave the same as other springs or elastic materials do under load. Because both the economic metaphor based on equilibrium theory of gases and the engineering analysis of bridges under load can both be subsumed under spring theory, we can treat both the economic (gas) metaphor and the engineering (bridge) metaphor as minor variations of a single overarching (spring) metaphor. Complex Systems Metaphors Holling (“Resilience & Stability” 13–15) critiques equilibrium models, arguing that non-deterministic, complex, non-equilibrium and multi-equilibrium ecological systems do not satisfy the conditions for application of equilibrium models. Holling argues that unlike the single equilibrium modelled by engineering resilience, complex adaptive systems (CAS) may have multi or no equilibrium states, and be non-linear and non-deterministic. Walker and Salt follow Holling by calling for recognition of the “dynamic complexity of the real world” (8), and that “these [real world] systems are complex adaptive systems” (11). Martin-Breen and Anderies (7) identify the key difference between “systems” and “complex adaptive systems” resilience as adaptive capacity, which like Walker and Salt (xiii), they define as the capacity to maintain function, even if system structures change or fail. The “engineering” concept of resilience focuses on the (elastic) properties of materials and uses language associated with elastic springs. This “spring” metaphor emphasises the property of individual components. In contrast, ecological concepts of resilience examine interactions between elements, and the state of the system in a multi-dimensional phase space. This systems approach shows that the complex behaviour of a system depends at least as much on the relationships between elements. These relationships can lead to “emergent” properties which cannot be reduced to the properties of the parts of the system. To explain these relationships and connections, ecologists and climate scientists use language and images associated with landscapes such as 2-D cross-sections and 3-D topology (Holling, “Resilience & Stability” 20; Pendall, Foster, and Cowell 74). Figure 3 is based on an image used by Walker, Holling, Carpenter and Kinzig (fig. 1b) to represent possible states of ecological systems. The “basins” in the image rely on our understanding of gravitational forces operating in a 3-D space to model “equilibrium” states in which the system, like the “ball” in the “basin”, will tend to settle. Figure 3: (based on Langston; in Walker et al. fig. 1b) – Tipping Point Bifurcation Wasdell (“Feedback” fig. 4) adapted this image to represent possible climate states and explain the concept of “tipping points” in complex systems. I have added the red balls (a, b, and c to replace the one black ball (b) in the original which represented the state of the system), the red lines which indicate the path of the ball/system, and the black x-y axis, in order to discuss the image. Wasdell (“Feedback Dynamics” slide 22) takes the left basin to represents “the variable, near-equilibrium, but contained dynamics of the [current] glacial/interglacial period”. As a result of rising GHG levels, the climate system absorbs more energy (mostly as heat). This energy can force the system into a different, hotter, state, less amenable to life as we know it. This is shown in Figure 3 by the system (represented as the red ball a) rising up the left basin (point b). From the perspective of the gravitational representation in Figure 3, the extra energy in the basin operates like the rotation in a Gravitron amusement ride, where centrifugal force pushes riders up the sides of the ride. If there is enough energy added to the climate system it could rise up and jump over the ridge/tipping point separating the current climate state into the “hot earth” basin shown on the right. Once the system falls into the right basin, it may be stuck near point c, and due to reinforcing feedbacks have difficulty escaping this new “equilibrium” state. Figure 4 represents a 2-D cross-section of the 3-D landscape shown in Figure 3. This cross-section shows how rising temperature and greenhouse gas (GHG) concentrations in a multi-equilibrium climate topology can lead to the climate crossing a tipping point and shifting from state a to state c. Figure 4: Topographic cross-section of possible climate states (derived from Wasdell, “Feedback” 26 CC). As Holling (“Resilience & Stability”) warns, a less “desirable” state, such as population collapse or extinction, may be more “resilient”, in the engineering sense, than a more desirable state. Wasdell (“Feedback Dynamics” slide 22) warns that the climate forcing as a result of human induced GHG emissions is in fact pushing the system “far away from equilibrium, passed the tipping point, and into the hot-earth scenario”. In previous episodes of extreme radiative forcing in the past, this “disturbance has then been amplified by powerful feedback dynamics not active in the near-equilibrium state [… and] have typically resulted in the loss of about 90% of life on earth.” An essential element of system dynamics is the existence of (delayed) reinforcing and balancing causal feedback loops, such as the ones illustrated in Figure 5. Figure 5: Pre/Predator model (Bellinger CC-BY-SA) In the case of Figure 5, the feedback loops illustrate the relationship between rabbit population increasing, then foxes feeding on the rabbits, keeping the rabbit population within the carrying capacity of the ecosystem. Fox predation prevents rabbit over-population and consequent starvation of rabbits. The reciprocal interaction of the elements of a system leads to unpredictable nonlinearity in “even seemingly simple systems” (“System Dynamics”). The climate system is subject to both positive and negative feedback loops. If the area of ice cover increases, more heat is reflected back into space, creating a positive feedback loop, reinforcing cooling. Whereas, as the arctic ice melts, as it is doing at present (Barber), heat previously reflected back into space is absorbed by now exposed water, increasing the rate of warming. Where negative feedback (system damping) dominates, the cup-shaped equilibrium is stable and system behaviour returns to base when subject to disturbance. [...]The impact of extreme events, however, indicates limits to the stable equilibrium. At one point cooling feedback loops overwhelmed the homeostasis, precipitating the "snowball earth" effect. […] Massive release of CO2 as a result of major volcanic activity […] set off positive feedback loops, precipitating runaway global warming and eliminating most life forms at the end of the Permian period. (Wasdell, “Topological”) Martin-Breen and Anderies (53–54), following Walker and Salt, identify four key factors for systems (ecological) resilience in nonlinear, non-deterministic (complex adaptive) systems: regulatory (balancing) feedback mechanisms, where increase in one element is kept in check by another element; modularity, where failure in one part of the system will not cascade into total systems failure; functional redundancy, where more than one element performs every essential function; and, self-organising capacity, rather than central control ensures the system continues without the need for “leadership”. Transition Towns as a Resilience Movement The Transition Town (TT) movement draws on systems modelling of both climate change and of Limits to Growth (Meadows et al.). TT takes seriously Limits to Growth modelling that showed that without constraints in population and consumption the world faces systems collapse by the middle of this century. It recommends community action to build as much capacity as possible to “maintain existence of function”—Holling's (“Engineering vs. Ecological” 33) definition of ecological resilience—in the face of failing economic, political and environmental systems. The Transition Network provides a template for communities to follow to “rebuild resilience and reduce CO2 emissions”. Rob Hopkins, the movements founder, explicitly identifies ecological resilience as its central concept (Transition Handbook 6). The idea for the movement grew out of a project by (2nd year students) completed for Hopkins at the Kinsale Further Education College. According to Hopkins (“Kinsale”), this project was inspired by Holmgren’s Permaculture principles and Heinberg's book on adapting to life after peak oil. Permaculture (permanent agriculture) is a design system for creating agricultural systems modelled on the diversity, stability, and resilience of natural ecosystems (Mollison ix; Holmgren xix). Permaculture draws its scientific foundations from systems ecology (Holmgren xxv). Following CAS theory, Mollison (33) defines stability as “self-regulation”, rather than “climax” or a single equilibrium state, and recommends “diversity of beneficial functional connections” (32) rather than diversity of isolated elements. Permaculture understands resilience in the ecological, rather than the engineering sense. The Transition Handbook (17) “explores the issues of peak oil and climate change, and how when looked at together, we need to be focusing on the rebuilding of resilience as well as cutting carbon emissions. It argues that the focus of our lives will become increasingly local and small scale as we come to terms with the real implications of the energy crisis we are heading into.” The Transition Towns movement incorporate each of the four systems resilience factors, listed at the end of the previous section, into its template for building resilient communities (Hopkins, Transition Handbook 55–6). Many of its recommendations build “modularity” and “self-organising”, such as encouraging communities to build “local food systems, [and] local investment models”. Hopkins argues that in a “more localised system” feedback loops are tighter, and the “results of our actions are more obvious”. TT training exercises include awareness raising for sensitivity to networks of (actual or potential) ecological, social and economic relationships (Hopkins, Transition Handbook 60–1). TT promotes diversity of local production and economic activities in order to increase “diversity of functions” and “diversity of responses to challenges.” Heinberg (8) wrote the forward to the 2008 edition of the Transition Handbook, after speaking at a TotnesTransition Town meeting. Heinberg is now a senior fellow at the Post Carbon Institute (PCI), which was established in 2003 to “provide […] the resources needed to understand and respond to the interrelated economic, energy, environmental, and equity crises that define the 21st century [… in] a world of resilient communities and re-localized economies that thrive within ecological bounds” (PCI, “About”), of the sort envisioned by the Limits to Growth model discussed in the previous section. Given the overlapping goals of PCI and Transition Towns, it is not surprising that Rob Hopkins is now a Fellow of PCI and regular contributor to Resilience, and there are close ties between the two organisations. Resilience, which until 2012 was published as the Energy Bulletin, is run by the Post Carbon Institute (PCI). Like Transition Towns, Resilience aims to build “community resilience in a world of multiple emerging challenges: the decline of cheap energy, the depletion of critical resources like water, complex environmental crises like climate change and biodiversity loss, and the social and economic issues which are linked to these. […] It has [its] roots in systems theory” (PCI, “About Resilience”). Resilience.org says it follows the interpretation of Resilience Alliance (RA) Program Director Brian Walker and science writer David Salt's (xiii) ecological definition of resilience as “the capacity of a system to absorb disturbance and still retain its basic function and structure.“ Conclusion This paper has analysed the ontological metaphors structuring competing conceptions of resilience. The engineering resilience metaphor dominates in psychological resilience research, but is not adequate for understanding resilience in complex adaptive systems. Ecological resilience, on the other hand, dominates in environmental and climate change research, and is the model of resilience that has been incorporated into the global permaculture and Transition Towns movements.
