Факторы формирования дружеских связей студентов
We consider the structure of social network of university students, and analyze factors that lead to the personal communication (friendship) network formation. Using the data from student survey and administrative information, we estimate the econometric models that assume homophily and propinquity effects on the likelihood of being friends. Specifically, we estimate linear and logistic probability models with and without fixed effects. The results confirm the significance of such friendship formation factors as sharing the same study group, living in dormitory, similar academic achievement and having the same gender. The probability of a tie increases with the number of similar attributes.
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.

The main reason the so-called "crisis of education" covers not only the rap-id changes in the system of knowledge and technology, but also the changes in the labor market, the prevalence of atypical employment. As a result, the univer-sity, by definition, can not train a specialist, fully satisfying the requirements of the employer. For example, the direction of "Advertising and public relations" proposes measures to resolve the existing contradictions.
The book’s stated objective is to uncover context, “how social capital interacts with social institutions.” It is part of a new wave of research on social capital that, dissatisfied with both macro analyses limited to societal patterns and micro analyses limited to actors’ conditions, seeks to understand the operation of networks at the meso-level: how institutions and organizations structure the transfer of resources across networks. It purports to make both theoretical and methodological contributions, the first by developing the concept of “institutional logics,” the latter by “casting diverse contextual settings as ‘generators’ of social relations”, and studying these contexts from multiple methodological perspectives.

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.
Smoking is a problem, bringing signifi cant social and economic costs to Russiansociety. However, ratifi cation of the World health organization Framework conventionon tobacco control makes it possible to improve Russian legislation accordingto the international standards. So, I describe some measures that should be taken bythe Russian authorities in the nearest future, and I examine their effi ciency. By studyingthe international evidence I analyze the impact of the smoke-free areas, advertisementand sponsorship bans, tax increases, etc. on the prevalence of smoking, cigaretteconsumption and some other indicators. I also investigate the obstacles confrontingthe Russian authorities when they introduce new policy measures and the public attitudetowards these measures. I conclude that there is a number of easy-to-implementanti-smoking activities that need no fi nancial resources but only a political will.
