Scrolling in Silence: Is Social Media Bridging Connections or Fueling Isolation?

Perceived functions and importance of digital media use and adolescent depression and suicidal ideation.

The popularity of the Web has allowed individuals to communicate and interact with each other on a global scale: people connect both to close friends and acquaintances, creating ties that can bridge otherwise separated groups of people. Recent evidence suggests that spatial distance is still affecting social links established on online platforms, with online ties preferentially connecting closer people. In this work we study the relationships between interaction strength, spatial distance and structural position of ties between members of a large-scale online social networking platform, Tuenti. We discover that ties in highly connected social groups tend to span shorter distances than connections bridging together otherwise separated portions of the network. We also find that such bridging connections have lower social interaction levels than ties within the inner core of the network and ties connecting to its periphery. Our results suggest that spatial constraints on online social networks are intimately connected to structural network properties, with important consequences for information diffusion.

The purpose of this paper is to assess the cyber risks associated with the development of Augmented Reality (AR) and Virtual Reality (VR) technologies also in relation to their use in the Metaverse. AR and VR represent one of the most recent and relevant technological advances that have been able to take advantage of the changes brought about by the ongoing digital transformation driven by Industry 4.0, and the pandemic crisis. Moreover, these technologies are also becoming relevant for their potential in war scenarios and military exploitation.A common goal for both technologies is to improve knowledge and operational processes, overcoming the amount of information that is received by normal observation mechanisms, reducing the interactive distance between different variables. Consequently, the fields of application are various and regard all sectors, stemming from the national defense to the health, industrial and educational sectors. The culmination of these technologies, and their applications, is reached by the recent project announced by the founder of Facebook called "Metaverse". Some of the cybersecurity challenges will be similar to and will certainly enhanced others, such as the security and privacy risks related to social media, conference and streaming platforms and even internet browsing. The future of VR and AR spaces will involve a huge increase in new devices connecting to each other, through the creation of new apps and connection bridges, requiring the elaboration and the storage of huge quantities of data. Moreover, laws rarely reflect the rapidly evolving ways in which people interact with each other online. In this context, virtual assets can become as critical as physical ones, creating a worth to be protected. As the opportunities are all encompassing, so are the risks and vulnerabilities, such as identity theft, spying and social engineering. Security of confidential and market data, privacy and security of virtual assets are the most critical issues, linked to the volatility and reliability of providers with respect to assets.Unfortunately, new technologies are often developed and brought to market long before cybersecurity issues are addressed. An early identification of the main cyber risks inherent in the application of AR and VR technologies and the provision of framework for possible solutions to the various issues identified could address the Metaverse new challenge.

Islamic authority continues into the era of information technology development, the most striking thing is the shift in authority in the current era. Virtual space has become a connecting bridge and producer of religious knowledge for Muslims. Every Muslim is their own authority, Muslims produce their religious understanding on each of their social media accounts. The question is whether religion in virtual spaces has lost its prominence in religious knowledge, or has this virtual world become a platform for spreading inclusive teachings. This research uses qualitative methods, by taking field data and then processing it with several theoretical perspectives. The result of the study in this research is that the presence of virtual space has given rise to a new typology of Islamic authority within the academic scope of UIN Sunan Ampel, namely virtual world Islamic authority

The principal way of performing user profiling is to investigate accumulated social media data. However, the problem of information asymmetry generally exists in user generated contents since users post multi-modal contents in social media freely. In this paper, we propose a novel text-image cooperation framework (COOPNet), a bridge connection network architecture that exchanges information between texts and images. First, we map the representations of both visual and sentiment enriched textual modalities into a cooperative semantic space to derive a cooperative representation. Next, the representations of texts and images are combined with their cooperative representation to exchange knowledge in the learning process. Finally, a multi-modal regression is leveraged to make cooperative decisions. Extensive experiments on the public PAN-2018 dataset demonstrate the efficacy of our framework over the state-of-the-art methods on the premise of automatic feature learning.
