Self-Perceived Attractiveness and Its Influence on the Halo Effect and the Similar-to Me Effect

The present research examined the influences of the halo effect and the similar-tome effect on physical and sexual attractiveness for hiring decisions. It was hypothesized that the halo effect would cause applicants rated highly in physical and sexual attractiveness to receive higher ratings of hireability than unattractive applicants.However, if the similar-to-me effect is influential for levels of attractiveness in hiring situations, participants who rated themselves as less attractive should favor unattractive applicants. The results did not show an interaction between participant self-ratings and ratings of hireability, indicating the similar-to-me effect does not apply to physical or sexual attractiveness. There was a main effect of sexual attractiveness of the applicant forhireability, showing support for the halo effect. This effect was only found for White applicants, potentially due to in-group bias and out-group homogeneity.

Policing and Islamophobia in Germany – The Role of Workplace Experience

This study starts from a recognition of the German police force as having a significant potential for promoting integration in contemporary multiethnic Germany. It employs three measures of Islamophobic attitudes and contact quality amongst a sample of 727 German police officers, and relates these to measures of job-satisfaction, political affiliation, individual responsibility, and recognition. The data reveal Islamophobia to be significantly linked to these variables. Detailed analyses indicate that the respondents’ experience of policing may produce levels of dissatisfaction that impacts upon their out-group attitudes. The implications of this for initiatives to promote police–Muslim relations are explored.

Definition einer kritischen Situation im Fussball - Ergebnisse einer Experten-Fokusgruppe

Einleitung Bei der Untersuchung von Ausschreitungen bei Fußballspielen sind kritische Situationen (KS) interessant, die sich durch eine erhöhte Spannung auszeichnen, aber nicht immer in Gewalt enden. Es stellt sich die Frage, an welchen Merkmalen eine KS in situ erkannt werden kann, und ob dies mit theoretischen Erklärungen verglichen werden kann, wie z.B. mit dem Aggravation and Mitigation Model (Hylander & Guvå, 2010). Methode Um Kriterien einer KS festzulegen, wurde eine Fokusgruppe (Bohnsack, 2007) mit fünf Experten für Zuschauergewalt durchgeführt: zwei Polizisten mit Leitungsfunktion, zwei Fanarbeiter sowie ein Fanverantwortlicher eines Fussballstadions. In der ersten Phase gestalteten die Teilnehmer die Diskussion nach einer offenen einleitenden Frage möglichst autonom. In der zweiten Phase stellte die Moderatorin Fragen zur Klärung früherer Aussagen und bisher nicht erwähnten Themen. Angesprochen wurden das Fanverhalten, Alkoholkonsum und das Verhalten der Polizei. Die ersten beiden Autoren führten unabhängig eine zusammenfassende qualitative Inhaltsanalyse (Mayring, 2008) des transkribierten Gesprächs durch, um die Aussagen zu strukturieren und zu kategorisieren. Ergebnisse und Diskussion Verschiedene Kriterien zur Identifizierung einer KS wurden gefunden, beispielsweise „fehlende Distanz zwischen Fans und Polizei“, „Vermummung der Fans“, „Zusammenrücken der Fangruppe“ sowie „Aktionen ausserhalb der Fanrituale“. Diese und weitere Kategorien lassen sich vier Überkategorien zuordnen und damit strukturieren. Es gelang, durch die Methode der Fokusgruppe, relevante und beobachtbare Faktoren zu identifizieren, um kritische Situationen im Kontext der Fußballzuschauer auch dann zu erkennen, wenn es nicht zu Ausschreitungen kommt. Dies ist eine wichtige Voraussetzung, um die Dynamik der Gewalteskalation oder Mitigation im Feld untersuchen zu können. Literatur Bohnsack, R. (2007). Gruppendiskussion. In U.

Perception of critical situations involving football fans: dynamics of conflict escalation and de-escalation

Title: The perception of critical situations involving football fans – how conflicts escalate or de-escalate Authors: Brechbühl, A.1, Schumacher, A.1 & Seiler, R.1 1Institute of Sport Science, University of Bern, Switzerland Abstract: Introduction: Fan violence in the context of football matches is a prominent issue in today’s western societies and Switzerland presents no exception. A lot of research has been conducted on reasons for fan violence, mostly with fans of national teams. A prominent model is the Elaborated Social Identity Model (ESIM; Drury & Reicher, 2000): ESIM highlights the importance of interactions between the involved groups and their effect on the development of social identities. Another model is the aggravation mitigation model (AM model; Hylander & Guvå, 2010) which illustrates factors that can contribute towards an escalation or non-escalation of group violence, such as the “categorization” of the opponent group. Despite these models, research about the individual perceptions, and in particular, what factors distinguish between an escalation versus a non-escalation of a potentially violent situation in domestic football, is as yet scarce. This explorative study examines perceptions of critical situations in the domestic football fan context in Switzerland. Methods: An explorative qualitative design was employed to gather data about critical situations (CS) around football matches of two clubs of the Raiffeisen Super League. A CS is defined as a setting in or around the football stadium where violence between football fans and another group could occur. Eight CS were identified and analysed. Fifty-nine narrative interviews with individuals involved in a CS, e.g. fans, police officers or security personnel, were conducted. Interviews were analysed using interpretative phenomenological analysis (IPA). Results: The involved opposing groups expressed group-specific perceptions. Furthermore a strong tendency to negatively stereotype the opponent group was observed. Provocative symbols, such as balaclavas or riot-gear uniforms, were considered as highly relevant for the interpretation of the situation. Successful communication and sufficient distance between opponent groups supported the appeasement of a CS. These findings also underline the importance of knowledge about the local fan culture. This culture serves as basis for the perception of legitimacy, which was assessed to be essential for a de-escalation of a CS by fans. Discussion/Conclusion: This study improves the understanding of fan violence in the domestic football context in Switzerland. Based on the results it is suggested to deploy security or police forces without riot gear but with the goal of seeking dialogue with the fans to increase the likelihood of a peaceful ending in a CS. The findings also support the applicability of the ESIM (Drury & Reicher, 2000) and the AM model (Hylander & Guvå, 2010) in the context of domestic fan violence. Due to possible differences in the local fan cultures in Switzerland, research in this area should be continued. References: Drury, J., & Reicher, S. (2000).

Evaluation of an inventory for the assessment of critical incidents involving football fans

Introduction: Fan violence is a frequent occurrence in Swiss football (Bundesamt für Polizei, 2015) leading to high costs for prevention and control (Mensch & Maurer, 2014). Various theories put forward an explanation of fan violence, such as the Elaborated Social Identity Model (Drury & Reicher, 2000) and the Aggravation Mitigation Model (Hylander & Guvå, 2010). Important observations from these theories are the multi-dimensional understanding of fan violence and the dynamics occurring in the fan group. Nevertheless, none of them deal with critical incidents (CIs) which involve a tense atmosphere combined with a higher risk of fan violence. Schumacher Dimech, Brechbühl and Seiler (2015) tackled this gap in research and explored CIs where 43 defining criteria were identified and compiled in an integrated model of CIs. The defining criteria were categorised in four higher-order themes “antecedents” (e.g. a documented history of fan rivalry), “triggers” (e.g. the arrest of a fan), “reactions” (e.g. fans masking themselves) and “consequences” (e.g. fans avoiding communication with fan social workers). Methods: An inventory based on this model is being developed including these 43 criteria. In an exploratory phase, this inventory was presented as an online questionnaire and was completed by 143 individuals. Three main questions are examined: Firstly, the individual items are tested using descriptive analyses. An item analysis is conducted to test reliability, item difficulty and discriminatory power. Secondly, the model’s four higher-order themes are tested using exploratory factor analysis (EFA). Thirdly, differences between sub-groups are explored, such as gender and agerelated differences. Results: Respondents rated the items’ importance as high and the quota of incomplete responses was not systematic. Two items were removed from the inventory because of low mean or a high rate of “don’t know”-responses. EFA produced a six-factor solution grouping items into match-related factors, repressive measures, fans’ delinquent behaviour, intra-group behaviour, communication and control and inter-group factors. The item “fans consume alcohol” could not be ordered into any category but was retained since literature accentuates this factor’s influence on fan violence. Analyses examining possible differences between groups are underway. Discussion: Results exploring the adequacy of this inventory assessing defining criteria of CIs in football are promising and thus further evaluative investigation is recommended. This inventory can be used in two ways: as a standardised instrument of assessment for experts evaluating specific CIs and as an instrument for exploring differences in perception and assessment of a CI e.g. gender and age differences, differences between interest groups and stakeholders.

Identity Entrepreneurs

In my previous article Racial Capitalism, I examined the ways in which white individuals and predominantly white institutions derive value from non-white racial identity. This process flows from our intense social and legal preoccupation with diversity. And it results in the commodification of non-white racial identity, with negative implications for both individuals and society. This Article picks up where Racial Capitalism left off in three ways. As a foundation, it first expands the concept of racial capitalism to identity categories more generally, explaining that individual in-group members and predominantly in-group institutions — usually individuals or institutions that are white, male, straight, wealthy, and so on — can and do derive value from out-group identities. Second, the Article turns from the overarching system of identity capitalism to the myriad ways that individual out-group members actively participate in that system. In particular, I examine how out-group members leverage their out-group status to derive social and economic value for themselves. I call such out-group participants identity entrepreneurs. Identity entrepreneurship is neither inherently good nor inherently bad. Rather, it is a complicated phenomenon with both positive and negative consequences. Finally, the Article considers the appropriate response to identity entrepreneurship. We should design laws and policies to maximize both individual agency and access to information for out-group members. Such reforms would protect individual choice while making clear the consequences of identity entrepreneurship both for individual identity entrepreneurs and for the out-group as a whole. A range of legal doctrines interact with and influence identity entrepreneurship, including employment discrimination under Title VII, rights of privacy and publicity, and intellectual property. Modifying these doctrines to take account of identity entrepreneurship will further progress toward an egalitarian society in which in-group and out-group identities are valued equally.

Predicting the Paths of Peripherals: The Interaction of Identification and Future Possibilities

Two studies investigated how both degree of identification and the individual's position within the group influence aspects of group loyalty. The authors considered ingroup position in terms of both the individual's current position within a group and expectations concerning the likelihood that one's position might change., in the future. Peripheral group members learned that their acceptance by other group members would improve in the future or that they could expect rejection by other group members. Various indices of group loyalty (ingroup homogeneity, motivation to work for the group, and evaluation of a motivated group member) showed that when group members anticipated future rejection, the lower the identification the less loyal they were. In contrast, those who expected future acceptance were more loyal (more motivated to work for the group) the lower their identification. Current group behavior depends on both intragroup future expectations and level of identification.

Trust me, I'm your boss: Trust and power in supervisor-supervisee communication

This study examined employees' perceptions of trust, power and mentoring in manager-employee relationships in a variety of sectors, including health care, education, hospitality and retail. The main theoretical frameworks used were communication accommodation theory and social identity theory, in examining the manager-employee relationships from an in-group/out-group perspective. Computer-aided content analyses revealed a number of emergent communication and relationship themes that impact upon the level of 'in-groupness' and therefore trust in supervisor-supervisee relationships. While it may be illusory to believe that any organization can enjoy complete trust among its workforce, it is clear that certain communication characteristics can result in greater trust in manager-employee relationships, even within the context of organizational constraints. It is argued that the results of the study could be used to inform human resource management academics of key aspects of managerial communication that should be further researched, and also provide insights into the main communication skills that managers should focus upon to improve trust in the workplace.

Why organizational and community diversity matter:the emergence of incivility and organizational outcomes

Integrating sociological and psychological perspectives, this research considers the value of organizational ethnic diversity as a function of community diversity. Employee and patient surveys, census data, and performance indexes relevant to 142 hospitals in the United Kingdom suggest that intraorganizational ethnic diversity is associated with reduced civility toward patients. However, the degree to which organizational demography was representative of community demography was positively related to civility experienced by patients and ultimately enhanced organizational performance. These findings underscore the understudied effects of community context and imply that intergroup biases manifested in incivility toward out-group members hinder organizational performance.

The relationship between expatriate job level and host country national categorization:an investigation in the UK

Using data from 493 host country nationals (HCNs) in the UK, we investigated relationships between expatriate gender, national origin, and job level, and HCN characteristics and willingness to help expatriates. Results showed that HCNs from the UK are likely to categorize expatriates as in-group or out-group members based on perceived values similarity, ethnocentrism, and collectivism. This categorization is also likely to affect HCN willingness to provide role information and social support to expatriates. Overall, our results suggest that HCNs would be more likely to provide role-related information to subordinates and peers than supervisors, and social support to male peers regardless of their nationality (i.e. USA vs. India). The analysis contributes to the fields of expatriate management, social categorization, and international human resource management. It also has key messages for multinational companies regarding the development of efficient expatriate management systems. © 2011 Taylor & Francis.

A influência da relevância social no viés de grupo

Behaviors found in every culture, general human tendencies, are knew in Evolutionary Psychology as evolved psychological mechanisms. Those behaviors date back the Environment of Evolutionary Adaptedness, and a well know example of such behavior is the group bias (or intergroup bias). This bias consists of recognizing members of your own group and favor them, while disregarding or even harming outsiders. This behavior was and still is extensively studies, among the most important conclusions about this phenomenon is the Minimal Groups Paradigm, in which it was discovered that the group bias could trigger even when the groupings were done in following very arbitrary criteria. In the current study, our goal was to test if the participants, when playing an economic game, would behave in a similar fashion under a minimal group situation and real groups, with social meaning. With this in mind we made two experimental conditions, a Low Social Meaning one (LSM) where the groups were represented by letters (H, B, O and Y) in which participants would be ramdomly assorted to each group; and the High Social Meaning condition (HSM) in which religion was used as a group marker, containing the two most dominating religious groups in Brazil, catholic and evangelic, another group containing all the other affiliations e the fourth and last group representing atheists and agnostics. The ratio of donations in-group/out-group was roughly the same across both conditions. However, the amount of wafers donated to ingroup was significantly bigger in the HSM condition. By verifying which aspects of the individual best predicted the observed group bias, we discovered that the in-group Entitativity perception as well as the Group Identification were the most relevant variables, however, only in the HSM condition. Simultaneously, by verifying the generosity, biased or not, we observed that the agreeableness personality factor was the only variable able to predict it, and only in the LSM condition. We conclude that our generosity, or the lack of it, is for most part defined by our personality, the Agreeableness factor in particular. But this very generosity can be biased by the social meaning of the involved groups and that, if the social meaning is big enough, even people who, thanks to their personality, normally wouldn’t show generosity, are able to do so when the receiver is an in-group member.

From labelling to social aid for immigrants in the 21st Century

Migration is as old as humanity, but since the 1990s migration flows in Western Europe have led to societies that are not just multicultural but so-called «super-diverse». As a result, Western towns now have very complex social structures, with amongst others large amounts of small immigrant communities that are in constant change. In this paper we argue that for social workers to be able to offer adequate professional help to non-native residents in town, they will need balanced view of ‘culture’ and of the role culture plays in social aid. Culture is never static, but is continually changing. By teaching social workers about how to look at cultural backgrounds of immigrant groups and about the limitations of then role that culture plays in communication, they will be better equipped to provide adequate aid and will contribute to making various groups grow towards each other and to avoid people thinking in terms of ‘out-group-homogeneity’. Nowadays, inclusion is a priority in social work that almost every social worker supports. Social workers should have an open attitude to allow them to approach every individual as a unique person. They will see the other person as the person they are, and not as a part of a specific cultural group. Knowledge about the others makes them see the cultural heterogeneity in every group. The social sector, though, must be aware not to fall into the trap of the ‘inclusion mania’! This will cause the social deprivation of a particular group to be forgotten. An inclusive policy requires an inclusive society. Otherwise, this could result in even more deprivation of other groups, already discriminated against. Emancipation of deprived people demands a certain target-group policymaking. Categorized aid will raise efficiency of working with immigrants and of acknowledging the cultural identity of the non-natives group. It will also create the possibility to work on fighting social deprivation, in which most immigrants can be found.
