Exploring social media network landscape of post-Soviet space

2019

The “post-Soviet space” consists of countries with a substantial fraction of the world’s population; however, unlike many other regions, its social media network landscape is still somewhat under-explored. This paper aims at filling this gap. To this purpose, we use anonymized data on user friendships at VK.com (also known as VKontakte and, informally, as “Russian Facebook”), which is the largest and most popular social media portal in the post-Soviet space with hundreds of millions of user accounts. Using the VK network snapshots from October 2015 to December 2016, we conduct a “multiscale” empirical study of this network by considering conn…

Personal branding or employee advocacy : expert's use of social networking site

2017

This paper deals with social media in building experts’ professional images. In the theoretical part, online communities are discussed in the light of the paper’s topic. The study relies on technological adoption models, and in particular, the UTAUT (Unified Theory of Acceptance and Use of Technology) 2 model. In the empirical part, the use of LinkedIn was analyzed as the major tool for professional networking. Our research results suggest that the use of LinkedIn has been initiated mostly by invitation or encouragement of another user. Only in rare occasions, self-branding was reported as the primary motivation to register into LinkedIn. Self-presentation was improved in the process of usi…

Application of Zero Exclusion Condition to Stability Analysis of Computer Networks

2016

Stability, or robust [Dscr ]-stability analysis of computer network considered as a dynamic system, relies on increasing the speed of data transmission while minimizing the queuing time delays of its packets in the router buffers that can affect the overall data flow of the network traffic. We consider a zero exclusion condition as an effective method for testing and analyzing the computer networks stability. Our findings indicate that keeping control over the queuing time delays as well as including some factors of the RED algorithm and its variants, which we present in this paper, can improve the quality of network services significantly. Our method can be applicable both to single-loop a…
