This issue of Philosophical Transactions of the Royal Society, Part A represents a summary of the recent discussion meeting ‘Communication networks beyond the capacity crunch’. The purpose of the meeting was to establish the nature of the capacity crunch, estimate the time scales associated with it and to begin to find solutions to enable continued growth in a post-crunch era. The meeting confirmed that, in addition to a capacity shortage within a single optical fibre, many other ‘crunches’ are foreseen in the field of communications, both societal and technical. Technical crunches identified included the nonlinear Shannon limit, wireless spectrum, distribution of 5G signals (front haul and back haul), while societal influences included net neutrality, creative content generation and distribution and latency, and finally energy and cost. The meeting concluded with the observation that these many crunches are genuine and may influence our future use of technology, but encouragingly noted that research and business practice are already moving to alleviate many of the negative consequences.

Technological developments have a major impact on user behavior. The rapidly evolving communication system and technology have provided numerous choices for people. The ever-shifting changes in the generation of communication networks have posed challenges for mobile network service providers to attract and retain customers. This study aims to prioritize the determinants of the adoption of mobile network service providers using the unified theory of acceptance and use of technology (UTAUT-2). In this study, data were collected from 660 mobile phone users in Haryana, India. A fuzzy analytical hierarchy process (F-AHP) was applied to arrange the priority or rank the factors based on the significance of the factors in explaining the adoption of mobile network service providers. Results of the study reveal that efforts expectancy is the highest-ranked and prioritized factor for the adoption of mobile network service providers followed by performance expectancy and facilitating conditions. However, social influence emerged as the least important factor. The present study provides theoretical implications for future researchers by synthesizing and prioritizing the important factors affecting technology acceptance. The practical implications offer a clearer insight to marketers for developing focused pragmatic strategies to retain customer loyalty. The study has considered only UTAUT-2 model constructs and used the F-AHP technique. Other factors may be considered in future studies. Other priority analysis techniques can also be used such as ISM and MICMAC analysis for further study. The research has been conducted in Haryana, India, and therefore, it needs to be tested in other areas/countries for generalizability. JEL Classification: O1, O2, O4

This study aimed at the role of knowledge of information technology in organizational ‎development, by identifying the role of using information technology on developing ‎the skills of principals and employees at Al-Ferar School from the point of view of ‎teachers and teachers, and identifying the feasibility of using information technology ‎to reduce the size of the administrative apparatus in the school, in addition to identify ‎the feasibility of using information technology to expand communication networks in ‎the school, and to know the feasibility of using information technology to sort out new ‎and advanced patterns of management in the school, in order to complete the study. ‎The analytical descriptive approach was followed, through the use of the ‎questionnaire as a tool for the study, and a sample of (42) teachers was selected ‎from the research community in a random manner. The central results of the study: ‎There is a high effect of (3.46) for the use of technology on the organizational ‎development of the Ferar School for Girls from the point of view of the teachers. ‎There is also a significant impact of the use of technology at a rate of (3.6) on the ‎development and administrative development in Ferar School for Girls from the point ‎of view of the teachers. There is an average effect of using technology, at an ‎average of (3.06) on reducing the size of the administrative apparatus in the Ferar ‎School from the point of view of teachers. There is also an impact of a high rate of ‎‎ (3.7) for the use of technology on the expansion of the communication network in the ‎Ferar School from the point of view of teachers and teachers. There is a high (3.4) ‎role for the use of technology to sort out new and developed administrative patterns ‎in the Ferar School from the point of view of the teachers. It also found that the use ‎of technology contributes by (69.9%) to the development of administrative skills in the ‎Ferar School from the point of view of teachers and teachers, and that the use of ‎technology contributes by (65.2%) to reducing the size of the administrative ‎apparatus, and the use of technology contributes by (86.1%) in Expanding the ‎communication network in the Freer School from the point of view of the teachers ‎and the teachers. The study also found that there is no significant effect for (the ages ‎of the respondents, educational qualifications, and years of experience) for their ‎answers about the feasibility of using technology on organizational development in ‎the Freer Secondary School from their point of view. In the wake of these results, the ‎study came out with recommendations, the most important of which are: the need to ‎proceed with the use of technology as a developmental tool in schools, and the need ‎to develop benefiting from this use, especially in the areas of developing ‎administrative skills. Similar prospective studies on broader groups of teacher ‎schools‎.‎ Key words:


The purpose of this discussion meeting was to consider in depth the structures of some selected biological membranes and envelopes - in particular, those with marked, morphological substructure. Where such substructure could be related to function, this also was considered, the aim being to illustrate by multidisciplinary techniques the interdependence of membrane morphology and physiology. Inevitably, as the discussion was restricted to two days, with such a ubiquitous and pantomorphic subject as biological membranes, the field had to be strictly limited. Some of the most important aspects of membrane function, including bioenergetics, transport mechanisms and membrane flow, were deliberately excluded, largely because they have been the subjects of recent discussion meetings either at the Royal Society or elsewhere. Despite such restrictions, we had a distinguished field of research workers from whom to select our speakers. We were indeed fortunate, that so many were able to come, from many parts of the world, and contribute to this meeting.

The article is devoted to the analysis of the advantages and risks of using distributed ledger technology in the tasks of logistics and supply chain management. The specificity of the blockchain system makes it possible to solve a number of critical problems of sales management in an enterprise, and, apparently, in one form or another, it will be introduced into economic and business practice. The use of technology will require a number of economic, legal and technological solutions, as well as taking into account new types of risks.

Most territorial songbirds live in communication networks where eavesdropping on vocal interactions may constitute an important option for gathering information regarding the relative dominance, condition and quality of individuals being eavesdropped upon. The relatively low costs and risks of eavesdropping, together with the obvious advantages of gaining such comparative information about other individuals, predict eavesdropping to be a widespread phenomenon even though it is not necessarily advantageous for the participants to be eavesdropped upon. Special eavesdropper strategies that facilitate eavesdropping (how best to eavesdrop) may therefore have evolved together with strategies for interacting that either co-facilitate (public signaling) or counter eavesdropping directly (private signaling) or indirectly by preventing any subsequent negative consequences of being eavesdropped upon (anonymity). This paper reviews the predictions for the strategies and also gives examples supporting their use by territorial songbirds in connection with vocal interactions.

The use of Information and Communication Technologies (ICT) has undoubtedly influenced children, adolescents, and young people's social interactions and behavior. The use of technology has not only positive but also negative consequences. In recent years, research has shifted from traditional bullying to new forms of bullying, such as cyberbullying. In Greece, there is a research gap in investigating this phenomenon among students of Ecclesiastical Schools. This paper investigates the frequency of bullying and victimization of these students through digital means, as well as their views on the role of Ecclesiastical Education in the prevalence of cyberbullying.

As employees increasingly use technology for personal purposes in the workplace, tensions between proponents of control versus flexibility are rising. Proponents of control emphasize negative consequences and argue for employee restrictions and monitoring, whereas those for flexibility highlight positive consequences and advocate for employee discretion. We build consensus between these two approaches by adopting the job demands–resources model to show why the personal use of technology at work has both negative and positive effects on organizational outcomes, and then, we theorize about several boundary conditions that mitigate or strengthen these effects. We discuss implications for human resource development (HRD) scholars and professionals.

With the advancement of technology, new modes of communication have emerged and are being used in the field of academics. Traditional media played a pivotal role in spreading knowledge in all sections of societies in the world. Traditional media proved to be a powerful tool in the process of making learning and teaching more effective, interesting, and simple to insure everyone benefits to the maximum. Social media are newly-emerged communication networks which are in use not only for sharing information but also for education, knowledge transfer, and for building a global community of academicians. Different tools of social media are in use in different streams of education. Over the years, it has been realized that both traditional and social media have much potential and use in education at all three levels e.g. primary, secondary, and higher education. But, the integration of traditional and social media still has a long way to go in terms of acceptance. This chapter highlights some major points related to changing academic environment, with the use of technology in classes, students vs. teachers' perspectives on learning and teaching, academics, and use of media – Traditional vs. New media in classes and integrating traditional and social media within the academic environment.
