The paradox of in-group love: differentiating collective narcissism advances understanding of the relationship between in-group and out-group attitudes
The article looks at the relation between positive in-group regard (“in-group love”) and out-group negativity (“out-group hate”), a subject of ongoing controversy. Five studies performed in different cultural and national contexts, using different samples (including an adult representative sample) and different inter-group contexts examined the relationship between narcissistic versus genuine positive group regard and out-group negativity. Results reveal that collective narcissism (Golec de Zavala et al., 2009) and positive group regard have opposite effects on out-group hostility. Moreover, they function as mutual suppressors. Controlling for their shared variance strengthens the positive relationship between collective narcissism and out-group negativity and reveals the significant negative association between out-group hostility and genuine positive group regard operationalized as high collective self-esteem (Study 1), positive in-group identification (Studies 2, 3 and 5) or constructive patriotism (Study 4). These results corroborate earlier findings differentiating between constructive and destructive forms of in-group favoritism. They also parallel at the inter-group level findings indicating that mature and stable, personal self-esteem and individual narcissism differentially predict interpersonal aggressiveness
Polymer nanocomposites reinforced with montmorillonite
Purpose: Light microscope with polarized light has been used for observation layered zone, visible thanks to polarization of the light, inside polymer-polymer composites and nanocomposites Aim of work has been concentrated on investigation of nanocomposites as promising engineering materials, basing on composition of polypropylene and montmorillonite as reinforcement in the shape of nanoparticles of 2:1 silicate. Design/methodology/approach: Conventional and non-conventional injection molding process has been used for obtaining nanocomposites. In non-conventional process has been used the special mold for inducing the shear rates, additionally equipped with external computer to control melt manipulation of solidifying polymer inside mold cavity Findings: Highly developed structure consisted of multilayer zone between skin and core mainly responsible for reinforcement and improvement of fracture toughness of polymer composites and nanocomposites Research limitations/implications: Nanocomposites of polymer blends and montmorillonite were moulded by direct injection moulding according to melt temperature and stroke time-number combination included in design of experiments. Practical implications: Application of special injection moulding technique provides to structure development and gives possibility to create multilayer zone, which strengthen material. Besides strengthening obtaining of such nanocomposites is cheap thanks to application of low cost injection moulding technique and not expensive polyolefines with developed structure, without using additional fillers (e.g. compatybilizers). Originality/value: Very wide application of polymer composites and nanocomposites as engineering materials used for various industries like building engineering, automotive and aerospace.- (undefined
The paradox of in-group love: Differentiating collective narcissism advances understanding of the relationship between in-group and out-group attitudes.
WOS:000313914400002 (Nº de Acesso Web of Science)Objective The present studies test the hypothesis that the overlap between collective narcissism and positive in-group identification conceals the opposite relationships these variables have with out-group derogation. Method Five surveys were conducted in different cultural and national contexts, using different samples and different intergroup contexts (Study 1, Polish student sample, N = 85; Study 2, British student sample, N = 81; Study 3, Polish representative sample, N = 979; Study 3, Polish student sample, N = 267 and Study 5, British student sample, N = 241). Results The results of suppression analyses systematically indicate that when the positive relationship between collective narcissism and in-group positivity is controlled for, the non-narcissistic in-group positivity predicts less out-group negativity, whereas collective narcissism predicts more out-group derogation. Conclusions The results advance our understanding of constructive and destructive forms of in-group positivity and their different consequences for intergroup attitudes
Complementary stereotyping of ethnic minorities predicts system justification in Poland
We investigate the phenomenon of complementary stereotyping of ethnic minorities in Poland and its relationship to system justification. Using results from a nationally representative survey we test the hypothesis that complementary stereotypes—according to which ethnic minorities are seen as possessing distinctive, offsetting strengths and weaknesses—would be associated with system justification among Polish majority citizens. For four minorities, results indicated that stereotyping them as (a) low in morality but high in competence or (b) high in morality but low in competence predicted greater system justification. These results suggest that even in a context that is low in support for the status quo, complementary stereotyping of ethnic minorities is linked to system justification processes. For the three minority groups that were lowest in social status, complementary stereotyping was unrelated to system justification. It appears that negative attitude towards these groups can be expressed openly, regardless of one’s degree of system justification
How do we get people into contact? Predictors of intergroup contact and drivers of contact seeking
Compared to the impressive amount of research on consequences of intergroup contact, relatively little work has been devoted to predictors of intergroup contact. Although opportunities for intergroup contact are constantly growing in modern diverse societies, these contact opportunities are not necessarily exploited. In the present review article, we describe current research on predictors of intergroup contact and drivers of contact seeking on a micro‐, meso‐, and macro‐level. We provide an overview of predictors, while focusing on recent research that is especially relevant for designing interventions and planning social policies aiming at increasing contact between different groups in varied societies. On the micro‐level, we discuss relational self‐expansion motives and confidence in contact as predictors of intergroup contact. On the meso‐level, we focus on the role of intragroup processes and historical intergroup conflicts in facilitating contact. On the macro‐level, we reflect on changing societal norms as a potential tool to increase the frequency intergroup contact. By focusing on the applied value of research findings, discussing diverse predictors, and applying a multilevel approach, we also address recent criticisms of the intergroup contact literature and demonstrate the generative nature of contemporary research in this area

What inverted U can do for your country: A curvilinear relationship between confidence in the social system and political engagement
We examined the link between political engagement and the tendency to justify the sociopolitical system. On one hand, confidence in the system should be negatively related to political engagement, insofar as it entails reduced desire for social change; on the other hand, system confidence should also be positively related to political engagement to the extent that it carries an assumption that the system is responsive to citizens' political efforts. Because of the combination of these 2 opposing forces, the motivation for political engagement should be highest at intermediate levels of system confidence. Five studies revealed a negative quadratic relationship between system confidence and normative political engagement. In 2 representative surveys, Polish participants with moderate levels of system confidence were more likely to vote in political elections (Study 1) and to participate in solidarity-based collective action (Study 2). Two field studies demonstrated a negative quadratic relationship between system confidence and actual participation in political demonstrations (gender equality and teachers' protests in Poland; Studies 3 and 4). This pattern of results was further corroborated by analyses of data from 50 countries drawn from the World Value Survey: we observed negative quadratic relationships between system confidence and collective action as well as voting. These relationships were stronger in democratic (vs. nondemocratic) regimes (Study 5). Our results suggest that some degree of system confidence might be useful to stimulate political engagement within the norms of the system

Outgroup helping as a tool to communicate ingroup warmth
Item does not contain fulltextThe authors extend previous research on the effects of metastereotype activation on outgroup helping by examining in more detail the role of group impression management motives and by studying direct helping (i.e., helping the outgroup believed to hold a negative view of the ingroup). Data from three experiments provided full support for the communicative nature of direct outgroup helping by demonstrating that outgroup helping in response to a negative metastereotype was predicted by participants' concern for the image of their ingroup, but not by their self-image concerns. Moreover, group image concerns predicted outgroup helping but not ingroup helping and predicted outgroup helping only when a negative metastereotype was activated, compared with a positive metastereotype, or a (negative or positive) autostereotype. The results also ruled out an alternative explanation in terms of denying the self-relevance of the metastereotype.1 juni 201
Mapping the meaning of "difference' in Europe: A social topography of prejudice
This paper draws on original empirical research to investigate popular understandings of prejudice in two national contexts: Poland and the United Kingdom. The paper demonstrates how common-sense meanings of prejudice are inflected by the specific histories and geographies of each place: framed in terms of ‘distance’ (Poland) and ‘proximity’ (United Kingdom), respectively. Yet, by treating these national contexts as nodes and linking them analytically the paper also exposes a connectedness in these definitions which brings into relief the common processes that produce prejudice. The paper then explores how inter-linkages between the United Kingdom and Poland within the wider context of the European Union are producing – and circulating through the emerging international currency of ‘political correctness’ – a common critique of equality legislation and a belief that popular concerns about the way national contexts are perceived to be changing as a consequence of super mobility and super diversity are being silenced. This raises a real risk that in the context of European austerity and associated levels of socioeconomic insecurity, negative attitudes and conservative values may begin to be represented as popular normative standards which transcend national contexts to justify harsher political responses towards minorities. As such, the paper concludes by making a case for prejudice reduction strategies to receive much greater priority in both national and European contexts
