Sociometric popularity is computed based on peer liking and dislike. The relation between sociometric popularity and perceived popularity, based on peer identification of school associates considered popular, was investigated in a sample of 727 middle school students (7th and 8th grades). Most sociometrically popular students were not high on perceived popularity. Most students high on perceived popularity were not sociometrically popular Perceived popularity was correlated more highly with a measure of dominance than was sociometric popularity. Sociometrically popular students who were not high on perceived popularity were characterized by peers as kind and trustworthy but not as dominant, aggressive, or stuck-up. Students who were high on perceived popularity but not sociometrically popular were characterized as dominant, aggressive, and stuck-up but not as kind and trustworthy. Sociometrically popular students who also were high on perceived popularity were characterized as kind, trustworthy, and dominant but not as aggressive or as stuck-up.

Emotional labor (EL) is the process by which employees manage their true feelings in order to express organizationally desired emotional displays. We develop and test components of an organizing framework for emotional labor wherein various aspects of emotional labor are understood through the underlying discordance versus congruence in felt versus displayed emotions. Meta-analytic results from 109 independent studies (total N ¼ 36,619) demonstrate that discordant emotional labor states are associated with a range of harmful consequences (health-, attitudinal-, and performance-related), whereas congruent emotional labor states do not incur these harmful consequences. We identify different patterns of worker-and work-related correlates on the basis of emotional discordance-congruence, as well as interesting occupational differences in these relationships. Lastly, we find discordant forms of emotional labor partially mediate the effects of organizational display rules on burnout, whereas congruent states do not mediate this relationship.

In this study, the associations between peer effects and academic functioning in middle adolescence (N = 342; 14-15 years old; 48% male) were investigated longitudinally. Similarity in achievement (grade point averages) and unexplained absences (truancy) was explained by both peer selection and peer influence, net of acceptance, and connectedness. Friendships were formed and maintained when adolescents had low levels of achievement or high levels of truancy. Friends influenced one another to increase rather than decrease in achievement and truancy. Moreover, friends' popularity moderated peer influences in truancy in reciprocal friendships but not in unilateral friendships, whereas friends' acceptance moderated peer influences in achievement in both unilateral and reciprocal friendships. The findings illustrate the dynamic interplay between peer effects and academic functioning.

Contemporary teams are self-assembling with increasing frequency, meaning the component members are choosing to join forces with some degree of agency rather than being assigned to work with one another. However, the majority of the teams literature up until this point has focused on randomly assigned or staffed teams. Thus, the purpose of the current study was to investigate how people do form into teams and how people should form into teams. Specifically, we utilized a sample of digital traces from a massively multiplayer online role-playing game (N = 1,568) to evaluate the bases for and performance implications of team self-assembly. The results indicated that self-assembled teams form via three mechanisms: homophily, familiarity, and proximity. Moreover, results of the trace data analyses indicated that successful and unsuccessful teams were homogeneous in terms of different characteristics, and successful teams formed based on friendship more often than unsuccessful teams did.
