—In next-generation wireless networks, device-todevice (D2D) communication represents a feasible way for mobile users to offload their cellular traffic demand without extra costs for deploying additional infrastructure from the network operators. Cellular (e.g., 3GPP LTE) network assistance can automate user/service discovery and connection establishment procedures, as well as enable secure D2D connectivity between proximate users. Currently, assisted direct connectivity is only available in the form of unlicensed-band protocols (e.g., WiFi Direct), which motivates research on understanding its practical limitations with realistic distributions of users and content. Whereas there are concerns that D2D communication alone may not be efficient due to limited content availability, in this paper, we advocate the use of network coding to upgrade assisted proximate communication and make it realize its full potential. In particular, we demonstrate that even simpler network coding techniques are capable to signifi- cantly improve the degrees of content availability for communicating users and thus enhance offloading performance under realistic constraints. Inspired by the recent popularity of wireless content distribution systems over D2D caches, we contribute a practical methodology for assisted data caching and distribution, mindful of the state-of-the-art D2D technology.
The age of new media that started in the late 1990s has problematized the integrity of personal identity. In this process, three factors are at play: 1. the condition of "late modern" western modernity that affects all social relations and implies individualization and "liquid" identities (Z.Bauman); 2. the development of new media as a burgeoning sphere, generating new ways of self-realization and "the search for oneself" online; and 3. the "human - interface" type of interaction in the new media, where the other to whom the person communicates could be not only another human being but also a computer. The main goal of this paper is to reveal the specific features of constructing the Self within the everyday use of new media, in particular blogs and multiplayer online games.
A woman’s body becomes a site of alarming attention and anxiety in modern Western culture. The preoccupation with the body seriously affects women’s psychological well-being and self-esteem, health and health related behaviours, relationships with others, and career. This article focuses onthe social influences on body perception and women’s individual lives. It reveals the complexity of a human body and women’s personal activity addressed to their bodies, and containsthe results of qualitative hermeneutical research of influential bodily sociocultural tendencies and women’s attitudes towards their bodies in modern Western culture.
