Friendship Selection

The current study examined whether youth’s perceived bullying norms play a role in friendship dynamics related to bullying and victimization among the fifth and sixth grade ( N = 736, 52% girls at Wave 1, N = 677, 52% girls at Wave 2) in elementary schools. Youth completed peer nominations (friendship, bullying, and victimization) and a self-reported measure of perceived bullying norms in the classroom. With longitudinal social network analysis (RSiena), this study investigated selection and influence of friends in bullying and victimization as well as the moderating role of perceived bullying norms in these processes. Results indicated that high bullying youth received many friendship nominations and tended to be more influenced by high bullying friends. In addition, highly victimized youth tended to form friendships with highly victimized peers, and youth whose friends are highly victimized became highly victimized themselves over time. As hypothesized, youth’s perceived bullying norms moderated these processes. As youth perceived higher bullying norms, the greater was the tendency for high bullying youth to select high bullying peers as friends and to be influenced by high bullying friends. Likewise, friend influence on victimization was magnified when youth perceived high bullying norms. The current study underscores the importance of youth’s perceived bullying norms in friendship dynamics of bullying and victimization.

Abstract Objective The current study uses methods from social network analysis to examine the relationship between chronic health conditions (CHCs) and adolescent friendships. Particular attention is given to the processes of peer marginalization, peer withdrawal and homophily related to CHCs. Methods Exponential random graph models were used to investigate the extent to which a CHC is associated with patterns in adolescent friendship connections, while controlling for important social network properties and covariates. The study uses cross-sectional data from six small US high schools (n = 461) within the National Longitudinal Study of Adolescent to Adult Health. Results Findings demonstrate no significant differences between adolescents with CHCs and adolescents without CHCs in the number of incoming friendship nominations (peer marginalization) or outgoing friendship nominations (peer withdrawal). In addition, similarity in CHCs (homophily) was not significantly related to friendship between two individuals. Conclusions In sum, the presence of an adolescent CHC was not significantly associated with adolescent social network structure, including peer marginalization, peer withdrawal, and homophily related to CHCs, after controlling for alternative social network processes. Although previous literature suggests that adolescents with CHCs experience negative social consequences, the current findings demonstrate that the social network structure of adolescents with CHCs did not differ significantly from that of their peers without CHCs. Thus, findings from the current study suggest that CHCs are not related to objective reductions in social connections.

Celem artykułu jest zaprezentowanie wyników badań , które skoncentrowane były na identyfikacja powiązań personalnych poprzez tzw. interlocking dyrektorski pomiędzy firmami uczestniczącymi w procesach przejęć w latach 2008-2014. Badaniami zrealizowanymi przy wykorzystaniu metody analizy sieci społecznych SNA (Social Network Analysis) objęto 525 spółek notowanych na GPW w Warszawie oraz NewConnect, które uczestniczyły w procesach akwizycji. W badaniach ważne było określenie poziomu usieciowienia poprzez interlocking dyrektorski pomiędzy firmami uczestniczącymi w omawianych transakcjach. Przyjmuje się, że jedną z podstawowych funkcji interlockingu jest redukcja niepewności i ograniczanie ryzyka poprzez dostęp do informacji dzięki połączeniu z radami innych firm. Przeprowadzone analizy wykazały, że poziom usieciowienia pomiędzy wszystkimi badanymi spółkami i osobami (członkami zarządów i rad nadzorczych) uczestniczącymi w transakcjach akwizycji w Polsce jest niski. Zidentyfikowane relacje miały charakter długotrwały i były widoczne zarówno przed transakcją, jak i po jej przeprowadzeniu.
