Analyzing the impact of storage shortage on data availability in decentralized online social networks

Maintaining data availability is one of the biggest challenges in decentralized online social networks (DOSNs). The existing work often assumes that the friends of a user can always contribute to the sufficient storage capacity to store all data. However, this assumption is not always true in today’s online social networks (OSNs) due to the fact that nowadays the users often use the smart mobile devices to access the OSNs. The limitation of the storage capacity in mobile devices may jeopardize the data availability. Therefore, it is desired to know the relation between the storage capacity contributed by the OSN users and the level of data availability that the OSNs can achieve. This paper addresses this issue. In this paper, the data availability model over storage capacity is established. Further, a novel method is proposed to predict the data availability on the fly. Extensive simulation experiments have been conducted to evaluate the effectiveness of the data availability model and the on-the-fly prediction

The Rise of Mobile and the Diffusion of Technology-Facilitated Trafficking

In this report, researchers at the USC Annenberg Center on Communication Leadership & Policy (CCLP) reveal how those involved in human trafficking have been quick to adapt to the 21st-century global landscape. While the rapid diffusion of digital technologies such as mobile phones, social networking sites, and the Internet has provided significant benefits to society, new channels and opportunities for exploitation have also emerged. Increasingly, the business of human trafficking is taking place online and over mobile phones. But the same technologies that are being used for trafficking can become a powerful tool to combat trafficking. The precise role that digital technologies play in human trafficking still remains unclear, however, and a closer examination of the phenomenon is vital to identify and respond to new threats and opportunities.This investigation indicates that mobile devices and networks have risen in prominence and are now of central importance to the sex trafficking of minors in the United States. While online platforms such as online classifieds and social networking sites remain a potential venue for exploitation, this research suggests that technology facilitated trafficking is more diffuse and adaptive than initially thought. This report presents a review of current literature, trends, and policies; primary research based on mobile phone data collected from online classified sites; a series of firsthand interviews with law enforcement; and key recommendations to policymakers and stakeholders moving forward

The Internet of Things Will Thrive by 2025

This report is the latest research report in a sustained effort throughout 2014 by the Pew Research Center Internet Project to mark the 25th anniversary of the creation of the World Wide Web by Sir Tim Berners-LeeThis current report is an analysis of opinions about the likely expansion of the Internet of Things (sometimes called the Cloud of Things), a catchall phrase for the array of devices, appliances, vehicles, wearable material, and sensor-laden parts of the environment that connect to each other and feed data back and forth. It covers the over 1,600 responses that were offered specifically about our question about where the Internet of Things would stand by the year 2025. The report is the next in a series of eight Pew Research and Elon University analyses to be issued this year in which experts will share their expectations about the future of such things as privacy, cybersecurity, and net neutrality. It includes some of the best and most provocative of the predictions survey respondents made when specifically asked to share their views about the evolution of embedded and wearable computing and the Internet of Things

Active Digiage? : Desirable Futures for Aging People

The changing age structure of population, with its growing number of ageing people, is a worldwide phenomenon among industrialized countries, and Finland is not an exception. This has implications for swiftly rising healthcare and social welfare costs, but also for new type of demand in related services, and thus creates business opportunities for Finnish know-how. Through qualitative semi-structured interviews this research builds understanding on the desires, needs and challenges that the ageing people have in their every-day life and especially in their use of digital technology and different kinds of digital services. This will further provide insight for the service creation for the needs of elderly people in Finland. The results presented in this paper are part of a larger research project, of which this paper represents the pilot study phase

The Role of Mobility Digital Ecosystems for Age-Friendly Urban Public Transport:A Narrative Literature Review

Within the context of the intersection of the global megatrends of urbanisation, ageing societies and digitalisation, this paper explores older people’s mobility, with a particular interest in public transport, and a strong consideration of digital/ICT elements. With a focus on (smart) mobility, the paper aims to conceptualise transport, one of the main domains of age-friendly cities as a core element of a smart, age-friendly ecosystem. It also aims to propose a justice-informed perspective for the study of age-friendly smart mobility; to contribute towards a framework for the evaluation of age-friendly smart transport as a core element of the global age-friendly cities programme that comprises mobility practices, digital data, digital networks, material/physical geographies and digital devices and access; and to introduce the term “mobility digital ecosystem” to describe this framework. The paper uses the method of a narrative literature review to weave together a selected range of perspectives from communications, transport, and mobility studies in order to introduce the embeddedness of both communication technology use and mobility practices into their material conditions. Combining insights from communications, mobility and transport and social gerontology with a justice perspective on ICT access and mobility, the paper then develops a framework to study age-friendly smart mobility. What we call a “mobility digital ecosystem” framework comprises five elements—mobility practices, digital data, digital networks, material geographies, digital devices and access to services. The paper contributes a justice-informed perspective that points towards a conceptualisation of age-friendly smart mobility as a core element of the age-friendly cities and communities in the WHO’s global age-friendly cities programme

“Who doesn’t think about technology when designing urban environments for older people?” A case study approach to a proposed extension of the WHO’s age-friendly cities model

The World Health Organization (WHO) strives to assist and inspire cities to become more “age-friendly”, and the fundamentals are included in the Global Age-Friendly Cities Guide. An age-friendly city enables residents to grow older actively within their families, neighbourhoods and civil society, and offers extensive opportunities for the participation of older people in the community. Over the decades, technology has become essential for contemporary and future societies, and even more imperative as the decades move on, given we are nearly in our third decade of the twenty-first century. Yet, technology is not explicitly considered in the 8-domain model by WHO, which describes an age-friendly city. This paper discusses the gaps in the WHO’s age-friendly cities model in the field of technology and provides insights and recommendations for expansion of the model for application in the context of countries with a high human development index that wish to be fully age-friendly. This work is distinctive because of the proposed new age-friendly framework, and the work presented in this paper contributes to the fields of gerontology, geography urban and development, computer science, and gerontechnology

The Elderly in the Digital World and Digital Inclusion of the Elderly: An Exemplary Mobile Application for the Elderly

In the modern day, technological developments are advancing exponentially, improving technology brings innovations in every corner of our lives, and with such innovations, the digital world is becoming more and more central to people’s lives. It is particularly important that the elderly also take part in this digital world, where especially young and middle-aged people are more likely to be involved. Our elders are our dearest and most respected family members whom we dote on and want to take care of with utmost attention. It is one of the noblest duties to increase their welfare, happiness, and life satisfaction by providing them with a safe, secure, and comfortable living environment. The elderly need to be actively involved in the digital world in order to benefit from the developments brought about by the digital world in a way to make their lives easier, such as maintaining social connections, following up on their health, staying healthy, making financial, banking and e-government transactions, using applications that facilitate their daily lives and remind them of important appointments or medication times. By the end of 2023, approximately 10 out of every 100 people living in the world will be elderly, and this figure is expected to increase to 12 in 2030 and 16 in 2050. Of all the applications developed in our constantly aging world; the necessity for mobile applications specifically for the elderly has also gradually increased and become more and more crucial in the world of applications. The applications to be developed for the elderly will facilitate the lives of both the elderly and those who are obliged to take care of them. The aim of this research is to contribute to the advancement of knowledge in the field of mobile application design for the elderly and to create a more inclusive and user-friendly technology for this growing user group. This article is analyzed in three parts. In the first section; the elderly population statistics of the Turkish Statistical Institute (TurkStat) for the year 2022 are studied on a detailed basis and the attributes of the elderly population aged 65 and over in Türkiye are examined by introducing a statistical overview of the subject. The second section deals with the topics about the elderly population; namely, what are the dangers ahead of the increasing elderly population, what are the challenges for families and individuals who are responsible for caring for the elderly, what are the most frequently diagnosed diseases in the elderly, what are the expectations of the elderly from their family members, what do the elderly feel most lonely about, and how should the city life be in order to facilitate the lives of the elderly. In light of the information put forth in the first part, the following topics are discussed in the second part: Why the elderly should be included in digitalization, what are the factors that increase the digital inclusion of the elderly, the obstacles to their digitalization, the dangers of their digitalization, the obstacles to the use of technology by the elderly, digital learning of the elderly, smart homes and wearable technologies. Although these issues may seem to be related to old age, they have been addressed because they are considered essential for understanding the elderly and identifying their needs for the mobile application to be developed. Finally, in the third part of the article, various applications developed for the elderly are reviewed and an exemplary mobile application for elderly is suggested.

Smart education as empowerment: outlining veteran teachers’ training to promote digital migration

Within the enhancement of technology and its ongoing integration into formal education setting, learning environments have been challenged to operationalize and arrange systems that engage pedagogy and technology together. The nature of this ongoing transformation is closely related to the paradigms that reign in the twenty-first century, in a scenario of what is now called a Fourth Industrial Revolution. School, despite losing its monopoly on knowledge diffusion, still plays a central role in educating new generations, therefore, it holds key responsibility in addressing contemporary logics of learning, living and becoming a citizen. Amidst the course of change and the ultimate calls for innovation in education, we encounter veteran teachers, professionals with a long teaching history, whose challenges include becoming familiar with new devices in order to fulfil their work demands. In this article, we then explore how central veteran teachers are for the progression to a smarter education scenario, through debating a training carried out in Portugal with 38 teachers from pre-school and k-12, aimed at promoting their digital migration. Data strengthen ties regarding teachers’ perceptions and attitudes in relation to technology and consequent resource on it as pedagogical tools. Also, the overall discussion of the training provides clues on how teacher-oriented actions might address their identity if meaningful output is desired, in order to support a real change of practice.Digital migrations and curricular innovation: giving new meaning to experience and rekindle teaching profession after 50 (Project number: PTDC/CED-EDG/28017/2017
