Health, Grades and Friendship: How Socially Constructed Characteristics Influence the Social Network Structure
Homophily - tendency for people to form social connections with similar others - is one of the key topics in social network analysis. It indicates to what extent people tend to be similar to their friends and in what dimensions. For the long time homophily was just an index of the social similarity, but for the recent years the interest for the homophily formation, dynamics and multidimensionality increased. In this paper we investigate the homophily in such social constructed behavior as food consumption and academic achievements. The study of body mass index in social network context reveals the presence of homophily, which means that persons with similar constitution are more likely to be interconnected with each other. Interestingly, that healthy food consumption has no impact on social network formation, but there is homophily based on fast food consumption. Thus, ‘bad habits’ are stronger forces for the social ties formation. This results show that social constructed behavior is an important component on the process of social network formation.
Since the first works on Higher Education Administration in the 1970s no comprehensive work in terms of purpose and scope of Higher Education has been published. There have been important changes in people’s aspirations vis-à-vis higher education globally. In parallel, the higher education systems, worldwide, have been undergoing constant transformation in response to these aspirations. From governments, employers and prospective students and their parents, the stakeholders in higher education system are now extremely varied paying close attention to the various aspects of higher education - from infrastructure, on-campus safety and security to administration, faculty and curricula. The present series attempts to take into account the issues of importance to all the stakeholders. Hence the series not only pays attention to the purpose and outcomes of higher education but also the economics surrounding higher education vis a vis marketization. The nitty gritty of running and maintaining a university infrastructure, impact of globalization and internationalization on delivery and demand of higher education, the commoditization of research, and changing paradigms of teaching and learning fall within the purview of the series. The increasing competition from other entities to provide degrees, certificates or other forms of credentials makes it important to have a work that brings all of the elements together to see how they actually interact and inter-relate from a systems perspective. The present series attempts to comprehensively attend to these issues and provide a complete reference resource to all those involved and interested in setting up of a Higher Education institution and its administration.
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.
Legal pluralism and the experience of the state in the Caucasus are at the centre of this edited volume. This is a region affected by a multitude of legal orders and the book describes social action and governance in the light of this, and considers how conceptions of order are enforced, used, followed and staged in social networks and legal practice. Principally, how is the state perceived and how does it perform in both the North and South Caucasus? From elections in Dagestan and Armenia to uses of traditional law in Ingushetia and Georgia, from repression of journalism in Azerbaijan to the narrations of anti-corruption campaigns in Georgia - the text reflects the multifarious uses and performances of law and order. The collection includes approaches from different scholarly traditions and their respective theoretical background and therefore forms a unique product of multinational encounters.
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.
