Too many friends, too little care: an exploration of the relational benefits and costs of friendship for academic self-efficacy, depression and anxiety in adolescence.

Our paper explores in a large Romanian sample (2168 adolescents) the relational costs and benefits of the number of friends at school. Using the MEDCURVE procedure to test the non-linear mediation effects, our results show that psychological safety, bullying and negative relations mediate the association between the number of friends and depression and anxiety, while social acceptance and bullying mediate the association between the number of friends and academic self-efficacy. In general, our results show that the relational benefits of friendship tend to diminish as the number of friends increase, in general over 9 friends (depending on the relational state) and parents, teachers and school counselors should help adolescents manage their number of friends in order to prevent the relational costs associated with engaging in too many (superficial) friendships.

Empowering leadership during the COVID-19 outbreak: Implications for work satisfaction and effectiveness in organizational teams.

The COVID-19 pandemic generated unprecedented challenges for social and organizational life. We set out to explore how empowering leadership and leadership support were affected as a result of the team-based organization starting to implement flexible and remote work practices after the outbreak of the COVID-19 pandemic. We collected data in a cross-lagged design and used the two-condition MEMORE mediation procedure to analyze data on work satisfaction and team effectiveness obtained just before and immediately after the COVID-19 outbreak in 34 organizational teams.

Multiple teams, multiple projects, multiple groups at the intersection of (multiple) research fields: A bibliometric study.

Multi-teaming is a concept studied across a variety of disciplines. While using a bibliometric approach on 255 research papers extracted from Web of Science, we aimed to depict the architecture of the multi-teaming concept across academic disciplines and time. Results of citation, co-citation and bibliographic coupling analyses identified four major fields looking at the concept of multi-teaming.

Death anxiety, death reflection and interpersonal communication as predictors of social distance towards people infected with COVID 19.

Our study investigates several antecedents and consequences of negative emotional reactions to the COVID-19 pandemic in a cross-national sample of 737 participants. Our results show that COVID-19 anxiety and negative mood are positively predicted by death anxiety and the use in communication of general COVID-19 information. Death reflection reduces negative mood in relation to COVID-19 and attenuates the positive association between death anxiety on the one hand and the negative mood and anxiety in relation to COVID-19 on the other hand.

Personality characteristics that are valued in teams: Not always "more is better"?

This study investigates the relationships between personality traits and contributions to teamwork that are often assumed to be linear. We use a theory-driven approach to propose that extraversion, agreeableness and conscientiousness have inverted U-shaped relationships with contributions to teamwork. In a sample of 220 participants asked to perform a creative task in teams, we found that extraversion, agreeableness and conscientiousness were curvilinearly associated with peer-rated contributions to teamwork in such a way that the associations were positive, with a decreasing slope, up to a peak, and then they became negative as personality scores further increased.

'We didn't know anything, it was a mess!' Emergent structures and the effectiveness of a rescue operation multi-team system.

Multi-team systems (MTS) are used to tackle unpredictable events and to respond effectively to fast-changing environmental contingencies. Their effectiveness is influenced by within as well as between team processes (i.e.

Personality, relationship conflict, and teamwork-related mental models.

This study seeks to explore whether neuroticism, agreeableness, and conscientiousness moderate the influence of relationship conflict experienced in groups on changes in group members' evaluative cognitions related to teamwork quality (teamwork-related mental models). Data from 216 students, nested in 48 groups were analyzed using a multilevel modeling approach. Our results show that the experience of relationship conflict leads to a negative shift from the pre-task to the post-task teamwork-related mental models.

Cognitive distance, absorptive capacity and group rationality: a simulation study.

We report the results of a simulation study in which we explore the joint effect of group absorptive capacity (as the average individual rationality of the group members) and cognitive distance (as the distance between the most rational group member and the rest of the group) on the emergence of collective rationality in groups. We start from empirical results reported in the literature on group rationality as collective group level competence and use data on real-life groups of four and five to validate a mathematical model. We then use this mathematical model to predict group level scores from a variety of possible group configurations (varying both in cognitive distance and average individual rationality).

When none of us perform better than all of us together: the role of analogical decision rules in groups.

During social interactions, groups develop collective competencies that (ideally) should assist groups to outperform average standalone individual members (weak cognitive synergy) or the best performing member in the group (strong cognitive synergy). In two experimental studies we manipulate the type of decision rule used in group decision-making (identify the best vs. collaborative), and the way in which the decision rules are induced (direct vs.

Decision rules and group rationality: cognitive gain or standstill?

Recent research in group cognition points towards the existence of collective cognitive competencies that transcend individual group members' cognitive competencies. Since rationality is a key cognitive competence for group decision making, and group cognition emerges from the coordination of individual cognition during social interactions, this study tests the extent to which collaborative and consultative decision rules impact the emergence of group rationality. Using a set of decision tasks adapted from the heuristics and biases literature, we evaluate rationality as the extent to which individual choices are aligned with a normative ideal.

Demographic diversity, communication and learning behaviour in healthcare groups.

An integrative model of group learning was tested in a sample of 40 healthcare groups (434 respondents), and the results show that age diversity reduces the frequency of face-to-face communication whereas educational diversity reduces the frequency of virtual communication in healthcare groups. Frequency of communication (both face-to-face and virtual), in turn, positively impacts on the emergence of trust and psychological safety, which are essential drivers of learning behaviours in healthcare groups. Additional results show that average educational achievement within groups is conducive for communication frequency (both face-to-face and virtual), whereas mean age within groups has a negative association with the use of virtual communication in healthcare groups.

Gender stereotypes in management: a comparative study of communist and postcommunist Romania.

This study sets out to investigate the changes in the perception of women in leading positions in communist and postcommunist Romania. The study uses a noninvasive paradigm of analyzing the content of obituaries for women and men in leading positions published in a national journal, and shows that the gender gap in management widened during the postcommunist period. In postcommunist Romania, women are perceived as being less able to lead/manage and more relational in their leadership style as compared to men, while in the communist period the gender differences were not significant.

Socially rejected while cognitively successful? The impact of minority dissent on groups' cognitive complexity.

The impact of minority dissent on group-level outcomes is explained in the current literature by two opposing mechanisms: first, through cognitive gains due to a profound change induced by minority members in the individual cognitions of the majority members, and second, through socio-affective process losses due to social rejection and relationship conflict. Groups are most effective in information processing if they succeed in solving this opposition and reduce the negative impact of process losses. The present study addresses this opposition using an experimental design in which we crossed minority dissent (presence vs.
