Dynamic characteristics of social networks users' behavior represent the toolkit for diagnosing the character and orientation of cyber communication.

Sixty-two (62) active participants of social networks were selected to answer the questions of the questionnaire. Further, on the grounds of the provided statistics of their accounts, quantitative characteristics of dynamics of cyber communication of participants' communicative behavior were analyzed using descriptive statistics and r-criterion of Spearman rank correlation. From the results, decrease in the level of intellectual communication of the youth in cyberspace provides a high level of the youth manipulative availability in social networks.

In this paper, we study the phenomenon of “digital” death, its genesis and the attitudes towards death in the context of social networks of students. As a result of the investigation we have discovered different forms of “digital death and the ways students react to it in social networks. We further investigate the origins of different user attitudes towards “digital death” and the impact of manipulative relation to death in social networks on the social reality. Some students stage their own death on social networks by posting images on their homepage, which has the intentions (i) to attract public attention, (ii) to express their auto aggression (iii) to make fun of death and (iv) to reduce their own anxiety of death by "sharing" the fear with other students. Our analysis shows that the main purpose of staging one’s death on social networks is to reduce the fear of death by creating plans, playing. Keywords: Students, cyberspace, social networks, death, "digital" death, attitude to the death in the social networks.

The work presents the materials of an empirical study aimed at identifying the link between adolescents' subjective experience of loneliness and their internet usage. 80 adolescents aged 11-15 (50% girls, 50% boys) took part in the study. The measurements have been carried out with the following: technique for diagnosing the level of subjective perception of loneliness; online involvement questionnaire; technique for screening diagnosis of cyber addiction.

The purpose is to identify personal determinants that predefine the effectiveness of sports among young people. In the process of studying personal determinants that predefine the effectiveness of sports among young people we applied the methods of logical, theoretical and comparative analysis, content analysis, interpretation and scientific data interpretation, generalisation and modelling. On the basis of theoretical analysis the study identified the most significant personal determinants for the increase in the effectiveness of sports among youth, developed a theoretical structural and functional psychological “Personal determinants of improving the effectiveness of sports among young people” model and determined the interrelation of intrapersonal structures mediating the process of the influence of biological, social and individual personal determinants to increase the effectiveness of sports among young people
