This study examined the collective behaviour of the police during a football match at the 2006 Football World Cup. What peacekeeping and aggravating processes could be identified and what were their consequences? Data were collected using observation and field interviews. Some critical situations could have escalated into riots; however, the police showed trust in the majority of the supporters' intentions to be peaceful. Distrust was reserved for selected individuals who were under surveillance. This, together with tactics involving using different forces for different tasks and an overall organisational strategy focusing on the festivity of the event, was the main reason for the peaceful outcome. A friendly but firm approach was successful in keeping the peace. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

Collective action is a group behavior that aims to improve the status, power, or influence of an entire group. The present study focused on hostile collective action performed for releasing negative emotions, and explored a pathway including the roles of general attitudes toward the advantaged group and situational group‐based anger in predicting the disadvantaged groups’ hostile collective action. Group‐level data were collected via a laboratory experiment. The results obtained using multiple regression analysis suggested that general attitudes toward the advantaged group formed before the trigger event predicted hostile collective action indirectly through the mediating effects of situational group‐based anger and collective action tendencies, which were both produced after that trigger event. In addition, situational group‐based anger predicted hostile collective action fully through collective action tendencies. These pathways provided a continuous process of hostile collective action in which general attitudes toward the advantaged group that were formed before the trigger events would influence situational group‐based anger when the trigger events occurred, and then affected hostile collective action for responding to these events. Thus, hostile collective action could be predicted before the trigger events by monitoring the disadvantaged groups’ attitudes toward the advantaged group. Moreover, reducing destructive collective action by improving intergroup attitudes through some effective interventions was discussed in this study.  相似文献

The purpose of this project was to do a qualitative study of an integrated and flexible ACT model, the Resource Group Assertive Community Treatment (RACT), as seen from the perspective of case managers in training. The resource group normally consists of the client, the case manager and other available personnel in the medical and support areas, as well as family members. Nineteen theses were randomly chosen from a set of 80 theses written by a group of Swedish trainee case managers. The exams were conducted as case studies and concerned 19 clients with psychotic problems, 11 men and 8 women. “The Empirical Phenomenological Psychological Method” was used in the analysis, which generated five overarching themes: (a) the RACT program; (b) the resource group; (c) the empowerment of the client; (d) progress in treatment; and (e) the case manager. These together constituted a “therapeutic circle,” in which methods and tools used within the RACT made it possible for the resource group to empower the clients who, as a result, experienced progress with treatment, during which the case manager was the unifying and connecting link.  相似文献

Drawing on evolutionary psychology, social exchange styles were conceptualized in terms of two dimensions of individual differences in approaching exchange relationships: Benefit‐seeking and cost‐vigilance. In Study 1, a principal components analysis of the Social Exchange Styles Questionnaire (SESQ) in 156 undergraduates confirmed the presence of two dimensions that were very similar to the expected dimensions: Equitable alliance building (EAB) and vigilant alliance management (VAM). The SESQ scales showed good internal consistency and construct validity. Multiple regressions confirmed that social exchange styles were distinct from other personality variables. In Study 2, multilevel modelling conducted on 45 small work groups demonstrated that EAB positively predicted members' subjective performance, while VAM positively predicted objective performance. Theoretical questions and future research directions are discussed. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

This study examined whether the effect of social group norms on 7‐ and 10‐year‐old children's aggression can be moderated or extinguished by contrary school norms. Children (n=384) participated in a simulation in which they were assigned membership in a social group for a drawing competition against an outgroup. Participants learnt that their group had a norm of inclusion, exclusion, or exclusion‐plus‐relational aggression, toward non‐group members, and that the school either had a norm of inclusion, or no such norm. Findings indicated that group norms influenced the participants' direct and indirect aggressive intentions, but that the school norm moderated the group norm effect, with the school's norm effect tending to be greater for indirect vs. direct aggression, males vs. females, and younger vs. older participants. Discussion focused on how school norms can be developed, endorsed, and presented so that they have their most lasting effect on children. Aggr.

This essay critiques dual-inheritance theory as presented in Peter Richerson and Robert Boyd's book Not by Genes Alone: How Culture Transformed Human Evolution (2005). The theory states that culture became prominent in human evolution because it allowed relatively rapid adaptation to changing environments by means of imitation. Imitating the behavior of other members of one's community produces adaptive behaviors more readily than either genetic evolution or individual learning. Imitation follows a number of patterns: imitating high-status individuals, imitating the most common forms of behavior, imitating behaviors perceived to be the most effective solutions to various problems relevant to survival. This process combined with occasional innovations in behavior lead to a process of cultural evolution involving populations of cultural variants. Different local human populations were associated with different local populations of cultural variants, and both the human and the cultural populations evolved over time. Human evolution cannot be understood without taking into account these parallel processes of genetic and cultural evolution. Not by Genes Alone traces the implication of dual-inheritance theory for understanding human evolution and refers to various bodies of evidence relevant to the theory.  相似文献

This paper examines the relationships between self‐identified crowd membership, attributional characteristics, and perceptions of parental style among students in their first year of high school (N = 893). The aim was to assess the extent to which group identity is reflected in self‐reported characteristics. Most students self‐identified either as studious, athletes, populars, rebels, or normals (N = 669) and also completed measures of perceptions of parental styles and attributional style. Consistent differences were observed between self‐identified studious and rebel teenagers. One‐way ANOVAS revealed significant group differences on mother's authoritativeness, father's authoritativeness, positive attributional style, and negative attributional style. These results are discussed with reference to the interplay between group influences and individual characteristics. Copyright © 2005 John Wiley & Sons, Ltd.  相似文献

Two studies tested a model, whereby, identification with the minority group was predicted to impact on acculturation preferences, which in turn were proposed to impact involvement in intragroup friendships with other minority members, intergroup friendships with majority members and stress experienced by minority members. A direct path from minority identification to stress was also included in the model. The model was tested using structural equation modelling on survey data collected from Muslim women (N = 250) and from Somali minority members (N = 198) in Britain. Results supported predictions and revealed that identification was associated with more culture maintenance preference and less culture adoption preference. Culture maintenance preference was associated with involvement in intragroup friendships, and culture adoption preference was associated with involvement in intergroup friendships and increased stress. Practical applications of the findings are discussed.  相似文献

Structural vector autoregressive models (VARs) hold great potential for psychological science, particularly for time series data analysis. They capture the magnitude, direction of influence, and temporal (lagged and contemporaneous) nature of relations among variables. Unified structural equation modeling (uSEM) is an optimal structural VAR instantiation, according to large-scale simulation studies, and it is implemented within an SEM framework. However, little is known about the uniqueness of uSEM results. Thus, the goal of this study was to investigate whether multiple solutions result from uSEM analysis and, if so, to demonstrate ways to select an optimal solution. This was accomplished with two simulated data sets, an empirical data set concerning children's dyadic play, and modifications to the group iterative multiple model estimation (GIMME) program, which implements uSEMs with group- and individual-level relations in a data-driven manner. Results revealed multiple solutions when there were large contemporaneous relations among variables. Results also verified several ways to select the correct solution when the complete solution set was generated, such as the use of cross-validation, maximum standardized residuals, and information criteria. This work has immediate and direct implications for the analysis of time series data and for the inferences drawn from those data concerning human behavior.  相似文献
