By analyzing the logs of corporate e-mail networks we found a number of patterns, showing how the size of ego-networks of individual employees changes on a day by day basis. We proposed a simple model that adequately describes the observed time dependence of an employee's "social circle". Comparison of experimental data with the theoretical model showed that employees are divided into two groups - with fast and slow changes in their social circles, respectively. We believe that the presence of these groups reflects both project-type and process-type of employees' activities. Comparison of data obtained before and during the global economic crisis has shown that the crisis led to an actual reduction in project-type activities.

Souvent considéré comme une activité des plus nuisibles, le piratage des contenus audiovisuels n’en constitue pas moins, depuis des décennies, pour de nombreuses populations aux quatre coins du monde, un moyen majeur d’accéder aux produits des industries culturelles. Nourri d’enquêtes de terrain, cet ouvrage explore les enjeux que recèle ce phénomène complexe. Cette étude inédite analyse les stratégies globales de lutte contre le piratage, évalue les politiques des autorités nationales, décrit les usages que font les publics des contenus audiovisuels piratés, retrace les chemins qu’empruntent ces derniers et s’intéresse à ceux qui font le commerce de ces produits, de même qu’aux mutations engendrées par internet en la matière.
The article discusses the phenomenon of interconnected glocal hospitality communities which have recently spread over the world in the context of the internet development and cultural globalization processes. It focuses on a typical community of users of CouchSurfi ng.org, a major social hospitality network in St. Petersburg. The author argues that, in the framework of this web service, there occurs a transformation of virtual groups of users localized in various spots of the globe into actual interconnected glocal communities which shape shared identities, norms, values, and practices among its members.
There have been implemented engineering and development of multi-agent recommender system «EZSurf» that performs analysis of interests and provides recommendations for the social network «VKontakte» users based on the data from profile of particular user. During the work process different methods and technological solutions have been analyzed with examination of their advantages and disadvantages. Besides of that the comparative analysis of analogous products has been held where the most similar is Russian start-up service - Surfingbird. Based on this analysis the decision of recommender system implementation and integration has been accepted. The feature of this system is that it uses social network “VKontakte” profile for user’s data collection and API of third-party services (LastFM, TheMovieDB) for an extraction of information about similar objects. Such an approach contributes into optimization of recommender system, because it does not require creation of its own object classification system and objects database. The functionality of multi-agent system was separated between three agents. First agent (Collector) collects user data from “VKontakte” profile using VK API. Second agent (Analyzer) collects similar objects from databases of thitd-party services (LastFM, TheMovieDB) that will be the criteria for further search of recommendatory content. For search and selection of information an agent (Recommender) that works as web-crawler has been implemented. System «EZSurf» can be exploited by the users of social network “VKontakte” in everyday life for time economy on web-surfing process. At the same time they will get recommendations on content that are filtered depending on preferences of every particular user.
Market growth of personal medical device comes from a number of factors: • Aging population requiring more attention; • Patients with chronic diseases may measure blood pressure and blood glucose at home; • Reducing the cost of these devices; • Ease of use and availability of medical devices; • Risen cost of a series of medical tests. This article discusses the new challenges that arise in the relationship doctor - patient in the remote Monitoring human healthcare. With the advent of a greater variety of low-cost medical devices, as well as low-cost high-quality mobile communication system will allow the system to tell the Remote Healthcare Monitoring System has also become possible. This system should be as ready to doctors and patients themselves. there is a new quality in the interaction between doctor and patient. Considers a new model of doctor-patient relationship in the light of the transfer of active interaction to the virtual world.
