The relationship between participation in civic and political activities and membership of voluntary associations is now well established. What is less clear is the relative impacts of how much time people spend on group activities (associational intensity), and the number and type of groups that individuals are involved with (associational scope). Does it matter in terms of civic engagement, for example, whether one is a member of a quilting-circle or trade union? Does it matter whether association ‘membership’ is simply an annual payment or a major commitment of time and energy? In this article, we use a large survey to explore these questions empirically by focusing on the membership patterns and civic engagement practices of 4,001 citizens drawn from eight suburbs across Greater Melbourne, Australia. Our findings indicate that, while associational intensity is positively related to civic engagement, associational scope (the number of group memberships per person), is a more influential determinant of the level of civic and political participation. The results also suggest that while all forms of associationalism are important in terms of fostering greater levels of civic activity, not all forms have the same impact.

Group membership is central to social interaction. Within peer groups, social hierarchies and affiliations are matters to which members seriously attend (Corsaro, 2014). Studies of peer groups highlight how status is achieved through oppositional actions. This paper examines the way in which competition and collaboration in a children’s peer group accomplishes status during the production and management of “second stories” (Sacks 1992). We present analysis of the interaction of young boys in a preparatory year playground who are engaged in a single instance of storytelling “rounds”. Analysis highlights the pivotal role of members’ contributions, assessments and receipts in a series of second stories that enact a simultaneously competitive and collaborative local order.

Effective leaders are believed to inspire followers by providing inclusive visions of the future that followers can identify with. In the present study, we examined the neural mechanisms underlying this process, testing key hypotheses derived from transformational and social identity approaches to leadership. While undergoing functional MRI, supporters from the two major Australian political parties (Liberal vs. Labor) were presented with inspirational collective-oriented and noninspirational personal-oriented statements made by in-group and out-group leaders. Imaging data revealed that inspirational (rather than noninspirational) statements from in-group leaders were associated with increased activation in the bilateral rostral inferior parietal lobule, pars opercularis, and posterior midcingulate cortex: brain areas that are typically implicated in controlling semantic information processing. In contrast, for out-group leaders, greater activation in these areas was associated with noninspirational statements. In addition, noninspirational statements by in-group (but not out-group) leaders resulted in increased activation in the medial prefrontal cortex, an area typically associated with reasoning about a person’s mental state. These results show that followers processed identical statements qualitatively differently as a function of leaders’ group membership, thus demonstrating that shared identity acts as an amplifier for inspirational leadership communication.

Este estudo analisa como a classe de acionistas afeta o valor das empresas brasileiras listadas na bolsa de valores no ponto de vista da governança corporativa. O trabalho examina a interação entre o valor das empresas e cinco tipos de concentrações acionárias comumente presente em mercados emergentes: famílias, agentes públicos, investidores estrangeiros, executivos e investidores financeiros nacionais. A análise empírica demonstra que o mix e a concentração de participação acionária afeta significativamente o valor das empresas. Utilizando uma compilação única de dados em painel de 2004 a 2008, a presente pesquisa também desenvolve hipóteses sobre o efeito da participação em grupos econômicos para o valor das empresas. A investigação encontra evidências de que, apesar de sua importância para o desenvolvimento de empresas brasileiras, o capital familiar, instituições públicas, e investidores estrangeiros estão cedendo lugar a monitores mais especializados e menos concentrados, como executivos e instituições financeiras nacionais. Estes resultados indicam que a governança corporativa no Brasil pode estar alcançando níveis de maturidade mais elevados. Adicionalmente, apesar de não haver indicação da existência de correlação entre a participação em grupos econômicos e o valor das empresas, os resultados indicam que a presença de um tipo específico de acionista em uma empresa do grupo facilita investimentos futuros desta classe de acionista em outras empresas do mesmo grupo, sinalizando que os interesses acionários são provavelmente perpetuados dentro de uma mesma rede de empresas. Finalmente, a pesquisa demonstra que enquanto o capital familiar prefere investir em empresas com ativa mobilidade do capital, investidores internacionais e instituições públicas procuram investimentos em equity com menor mobilidade de capital, o que lhes garante mais transparência com relação ao uso dos recursos e fundos das empresas.

Three studies examine how people’s attributions of responsibility for terrorist attacks depend on their group membership and their identification with the victim (study 1) or their identification with the victim’s or perpetrator’s ingroup (studies 2 and 3). We observe that people’s group membership (perpetrator group versus victim group) determines the judgments of responsibility for recent terrorist attacks. Members of the perpetrator group hold the direct perpetrators responsible, while members of the victim group perceive the perpetrator world as a whole as relatively responsible as well. Identification with the victim (study 1) or victim group (studies 2 and 3) strengthens attributions of responsibility to the whole perpetrator group, and this relationship is partially mediated by the perceived typicality of the perpetrator for the whole group. We discuss possible explanations for this pattern, and indicate the implications of these results in terms of improving intergroup relations.

Support among US citizens for severe interrogation has been recognized as drawing upon utilitarian as well as on retributive motivation (Carlsmith & Sood, 2009). Two studies were conducted to expand on these findings in a Swiss sample. In Study 1, participants rated the severity of different interrogation techniques, which were scaled to provide an alternative measure of interrogation severity. In Study 2, retributive motivation was manipulated by varying the terrorist past of a male suspect, and utilitarian motivation was manipulated by varying the probability that the suspect could provide valuable information. Additionally, we manipulated the suspect’s group membership. The results of the vignette study suggest that the number and severity of recommended interrogation techniques is mainly influenced by whether the suspect might provide valuable information. Whether the suspect had a terrorist past was an additional influence that, however, was primarily attributable to the suspect’s group membership: If the suspect belonged to the ingroup, participants’ harsher interrogation recommendations were affected by that person’s past, whereas recommendations were not significantly influenced by a terrorist past if the suspect was an outgroup member.

An experiment was conducted to investigate the idea that an important motive for identifying with social groups is to reduce subjective uncertainty, particularly uncertainty on subjectively important dimensions that have implications for the self-concept (e.g., Hogg, 1996; Hogg & Mullin, 1999). When people are uncertain on a dimension that is subjectively important, they self-categorize in terms of an available social categorization and, thus, exhibit group behaviors. To test this general hypothesis, group membership, task uncertainty, and task importance were manipulated in a 2 x 2 x 2 between-participants design (N = 128), under relatively minimal group conditions. Ingroup identification and desire for consensual validation of specific attitudes were the key dependent measures, but we also measured social awareness. All three predictions were supported. Participants identified with their group (H1), and desired to obtain consensual validation from ingroup members (H2) when they were uncertain about their judgments on important dimensions, indicating that uncertainty reduction motivated participants towards embracing group membership. In addition, identification mediated the interactive effect of the independent variables on consensual validation (H3), and the experimental results were not associated with an increased sense of social awareness and, therefore, were unlikely to represent only behavioral compliance with generic social norms. Some implications of this research in the study of cults and totalist groups and the explication of genocide and group violence are discussed.

The purposes of this research are: (1) to compare the similarides and differences in intra-group and inter-group social rules of hospital doctors and nurses; (2) to compare rule following, rule breaking & tolerance of rule breaking of doctors and nurses with respect to different work reladonships. Professional discipline and idendficadon, ingroup-outgroup membership and reladve status were used as predictors. In-depth interview of 20 doctors and 20 nurses were conducted to elicit social rules and goals. In the second study, 30 rules and 10 goals with high consensus were selected from study one and developed into a quesdonnaire which measured their applicadon to four different work reladonships, namely, padents, peers, seniors and doctors/nurses. Forty-three doctors and one hundred and seven nurses completed this questionnaire. In the third study, the frequency and goals of violation and tolerance of violation of five different social rules were measured. One hundred and thirty-six doctors and one hundred and sixty-six nurses completed the questionnaire.

Purpose – Social loafing is described in the literature as a frequent problem reducing individuals' performance when working in groups. This paper aims to utilize the social identity approach and proposes that under conditions of heightened group salience social loafing can be reduced and turned into social laboring (i.e. increased performance). Design/methodology/approach – Two experimental studies are conducted to examine the impact of participant's group membership salience on task performance. In Study 1, school teachers work either in coactive or in collective working conditions on brainstorming tasks. In Study 2, participants perform both a brainstorming task and a motor task. Findings – The results show social laboring effects. As predicted, participants in the high salient group conditions outperform participants in the low salient group conditions and the coactive individual condition. Practical implications – The results indicate that rather than individuating group members or tasks to overcome social loafing, managers can increase group performance by focusing on group members' perceptions of their groups as important and salient. Originality/value – The studies presented in this paper show that social identity theory and self categorization theory can fruitfully be applied to the field of group performance. The message of these studies for applied settings is that collective work in groups must not necessarily negatively impact performance, i.e. social loafing. By heightening the salience of group memberships groups can even outperform coactively working individuals.

Two experiments are reported which investigate the influence of ingroup and outgroup minority influence where group membership was determined according to a trivial dimension. The results of the first experiment replicate an earlier study and show that an ingroup minority has significantly more influence than an outgroup minority. In the second study the connotations associated with membership of the ingroup and outgroup (positive/negative) were experimentally manipulated. When ingroup/outgroup membership was associated with a positive/negative image respectively, the ingroup minority had the most influence. However, when ingroup/outgroup membership was associated with a negative/positive image, as predicted, an outgroup minority had more influence than an ingroup minority. These results are interpreted as supporting an intergroup analysis of minority influence processes.

Although theory on team membership is emerging, limited empirical attention has been paid to the effects of different types of team membership on outcomes. We propose that an important but overlooked distinction is that between membership of real teams and membership of co-acting groups, with the former being characterized by members who report that their teams have shared objectives, and structural interdependence and engage in team reflexivity. We hypothesize that real team membership will be associated with more positive individual- and organizational-level outcomes. These predictions were tested in the English National Health Service, using data from 62,733 respondents from 147 acute hospitals. The results revealed that individuals reporting the characteristics of real team membership, in comparison with those reporting the characteristics of co-acting group membership, witnessed fewer errors and incidents, experienced fewer work related injuries and illness, were less likely to be victims of violence and harassment, and were less likely to intend to leave their current employment. At the organizational level, hospitals with higher proportions of staff reporting the characteristics of real team membership had lower levels of patient mortality and sickness absence. The results suggest the need to clearly delineate real team membership in order to advance scientific understanding of the processes and outcomes of organizational teamwork.
