We examined the relation between adolescent separation-individuation, family cohesion, and college adjustment. A large sample of college students was split into two groups. One group was used to determine whether several measures of separation-individuation were measuring different dimensions of individuation. Two related factors, labeled Positive Separation Feelings and Independence From Paren...

We study the cohesion within and the coalitions between political groups in the Eighth European Parliament (2014-2019) by analyzing two entirely different aspects of the behavior of the Members of the European Parliament (MEPs) in the policy-making processes. On one hand, we analyze their co-voting patterns and, on the other, their retweeting behavior. We make use of two diverse datasets in the...

Choice tests have been widely used to assess animal preferences. In the case of group-living species, these tests are commonly presented to animals in groups, because isolation can have strong effects on behaviour and motivation. However, assessing preference at the group level could be misleading if strong control of movement, through influential individuals, and group cohesion were present. T...

Members of virtual communities generally expect that their groups satisfy some given requirements. For this aim, the profile matching between user requirements and group characteristics can be considered as the most natural way to represent the group homogeneity, measuring how much the group members are mutually linked. However, optimizing profile matching does not guarantee that the group will...

Four studies examined attachment-style differences in group-related cognitions and behaviors. In Studies 1-2, participants completed scales on group-related cognitions and emotions. In Studies 3-4, participants were divided into small groups, and their performance in group tasks as well as the cohesion of their group were assessed. Both attachment anxiety and avoidance in close relationships we...

*Correspondence: [email protected] Complex Systems and Artificial Intelligence research center, Università degli Studi di Milano–Bicocca, Milano, Italy Abstract Purpose: A crowd of pedestrians is a complex system in which individuals exhibit conflicting behavioural mechanisms leading to self-organisation phenomena. Computer models for the simulation of crowds represent a consolid...

Cohesion and structural equivalence are two competing network models to explain diffusion of innovation. The dispute of which model plays a more influential role has not been resolved. This paper attempts to reconcile this problem in a large network setting – adoption of caller ringback tone (CRBT) in a cellular telephone conversation network. Since this societal scale network is very large, we...

This article examines the effects of status differentiation on the cohesion of a social structure. Using a formal model, we simulate the fates of a hypothetical cohort of newly hired employees, who are equals in the eyes of their boss and in the nascent stages of sorting into a status hierarchy. We cast these employees in a process in which they exert effort, receive public approval from the bo...

In recent years, there has been an increase in the use of challenge course programs and activities, including low-element challenge courses, as interventions in clinical treatment facilities, as well as a treatment approach for adolescents with behavioral and social problems (Johnson, 1992), an approach to encourage personal growth (Herbert, 1996; Nassar McMillan & Cashwell, 1997), and as a met...

Preliminary results from an experimental study of readers’ perceptions of lexical cohesion and lexical semantic relations in text are presented. Readers agree on a common “core” of groups of related words and exhibit individual differences. The majority of relations reported are “non-classical” (not hyponymy, meronymy, synonymy, or antonymy). A group of commonly used relations is presented. The...
