A test of the extended intergroup contact hypothesis: The mediating role of intergroup anxiety, perceived ingroup and outgroup norms, and inclusion of the outgroup in the self

S. C. Wright, A. Aron, T. McLaughlin-Volpe, and S. A. Ropp (1997) proposed that the benefits associated with cross-group friendship might also stem from vicarious experiences of friendship. Extended contact was proposed to reduce prejudice by reducing intergroup anxiety, by generating perceptions of positive ingroup and outgroup norms regarding the other group, and through inclusion of the outgroup in the self. This article documents the first test of Wright et al.'s model, which used structural equation modeling among two independent samples in the context of South Asian-White relations in the United Kingdom. Supporting the model, all four variables mediated the relationship between extended contact and outgroup attitude, controlling for the effect of direct contact. A number of alternative models were ruled out, indicating that the four mediators operate concurrently rather than predicting one another.

Extended contact through cross-group romantic relationships

Cross-group romantic relationships are an extremely intimate and often maligned form of intergroup contact. Yet, according to intergroup contact theory, these relationships have the potential to improve the intergroup attitudes of others via extended contact. This study combines the interpersonal and intergroup literatures to examine the outcomes associated with knowing a partner in a cross-group romantic relationship. Results suggest that cross-group romantic partners encounter greater disapproval toward their relationships than same-group partners and, as a result, their relationships are perceived more negatively. Nevertheless, extended contact with cross-group partners, controlling for participants' cross-group friendships and romantic relationships, predicts more positive attitudes toward cross-group dating and positive intergroup attitudes in general, mediated by perceived ingroup norms toward cross-group relationships.

Phenotypic plasticity of composite beef cattle performance using reaction norms model with unknown covariate

The objective of the present study was to determine the presence of genotype by environment interaction (G × E) and to characterize the phenotypic plasticity of birth weight (BW), weaning weight (WW), postweaning weight gain (PWG) and yearling scrotal circumference (SC) in composite beef cattle using the reaction norms model with unknown covariate. The animals were born between 1995 and 2008 on 33 farms located throughout all Brazilian biomes between latitude -7 and -31, longitude -40 and -63. The contemporary group was chosen as the environmental descriptor, that is, the environmental covariate of the reaction norms. In general, higher estimates of direct heritability were observed in extreme favorable environments. The mean of direct heritability across the environmental gradient ranged from 0.05 to 0.51, 0.09 to 0.43, 0.01 to 0.43 and from 0.12 to 0.26 for BW, WW, PWG and SC, respectively. The variation in direct heritability observed indicates a different response to selection according to the environment in which the animals of the population are evaluated. The correlation between the level and slope of the reaction norm for BW and PWG was high, indicating that animals with higher average breeding values responded better to improvement in environmental conditions, a fact characterizing a scale of G × E. Low correlation between the intercept and slope was obtained for WW and SC, implying re-ranking of animals in different environments. Genetic variation exists in the sensitivity of animals to the environment, a fact that permits the selection of more plastic or robust genotypes in the population studied. Thus, the G × E is an important factor that should be considered in the genetic evaluation of the present population of composite beef cattle. © The Animal Consortium 2012.

Application of Reactions Norms in Study of Genotype Environmental Interaction for Milk Yield of Buffaloes

The aim of this study was to estimate genetic parameters for milk yield (MY) in buffaloes using reaction norms. Model included the additive direct effect as random and contemporary group (herd and year of birth) were included as fixed effects and cow age classes (linear) as covariables. The animal additive direct random effect was modeled through linear Legendre polynomials on environment gradient (EG) standardized means. Mean trends were taken into account by a linear regression on Legendre polynomials of environmental group means. Residual variance was modeled trough 6 heterogeneity classes (EG). These classes of residual variance was formed : EG1: mean = 866,93 kg (621,68 kg-1011,76 kg); EG2: mean = 1193,00 kg (1011,76 kg-1251,49 kg); EG3: mean = 1309,37 kg (1251,49 kg -1393,20 kg); EG4: mean = 1497,59 kg (1393,20 kg-1593,53 kg); EG5: mean = 1664,78 kg (1593,53 kg -1727,32kg) e EG6: mean = 1973,85 kg (1727,32 kg -2422,19 kg).(Co) variance functions were estimated by restricted maximum likelihood (REML) using the GIBBS3F90 package. The heritability estimates for MY raised as the environmental gradient increased, varying from 0.20 to 0.40. However, in intermediate to favorable environments, the heritability estimates obtained with Considerable genotype-environment interaction was found for MY using reaction norms. For genetic evaluation of MY is necessary to consider heterogeneity of variances to model the residual variance.

Tradurre per le imprese. Analisi e traduzione in inglese della Nota integrativa al Bilancio consolidato 2013 di MNLG S.r.l.-Holding Sorma Group

The aim of this dissertation is to provide a translation in English of the Notes on the Consolidated Financial Statements of MNLG S.r.l., holding company of the Italian Sorma Group. This translation work is one example of the technical material produced in accordance with the project called Language Toolkit, set up by the Chamber of Commerce of Forlì-Cesena, to support the internationalization of the companies established in the territory. This initiative has represented a unique opportunity for me to put into practice the knowledge and abilities learnt in the translation field during these years at university. It also allowed me to give a concrete purpose to my dissertation, that is to provide a technical document translated into a foreign language. By making its Consolidated Financial Statement readily available in English, the company MNLG S.r.l. can in fact increase the number of possible investors and guarantee a more transparent financial informative to its shareholders. This translation work is divided into six chapters: the first one describes the project, its main objectives and the ways in which it was developed. The second chapter deals with the notions of Consolidated Financial Statements and presents the accounting documents of which the Financial Statements are made up as well as the norms according to which they are prepared. The third chapter, instead, focuses on the translation procedure applied and especially on the documentation process, analysing the differences between the International Accounting Standards and the accounting standards used in Italy. The fourth chapter provides a description of the translation resources built for the translation of this specific document. The fifth chapter includes the English version of the Notes on the Consolidated Financial Statements and, to conclude, the sixth chapter analyses the difficulties encountered in translating and the strategies adopted to overcome them.

The Function of Norms and Values in the Construction of Social Identity in Groups who experienced intergroup Conflicts

I present my explorative research about conflict and social identity. The Social Identity Approach of Henri Tajfel and John Turner is used as theoretical frame in the study. The main question is how the construction of social identity of group members is influenced by an inter-group conflict. The research project consists of two parts: 1. An empirical study conducted with qualitative research methods to investigate a today’s congregation of the Swiss reformed Church who experienced a conflict about twenty years ago. This conflict ended by the separation of a sub-group from the congregations. This group forms an independent community today. Members of both congregations where interviewed about the meaning which membership has for them and about their interpretation of the conflict. 2. An analysis of the Gospel of Matthew with questions who where developed out of the empirical study and the Social Identity Approach to better understand the separation conflict between the Matthean community and the synagogue.

"What do other people think?" - The role of prejudice and social norms in the expression of opinions against gay men

It is generally acknowledged that it is no longer socially acceptable to espouse prejudiced beliefs, yet prejudiced attitudes and discriminatory behaviours still occur. The present study sought to determine when and by whom prejudiced attitudes would be expressed. Specifically, an experiment was conducted to examine the impact of injunctive social norms emanating from a social group with which participants identified and participants' level of homophobia on the expression of opinions about gay men. Participants were presented with information indicating that the majority of group members agreed with a number of prejudiced injunctive statements (pro-prejudice norm), that the majority disagreed with the statements (anti-prejudice norm), or they were given no information about other group members' opinions (control). Participants then reported their own responses to the same injunctive statements. Participants' levels of homophobia were assessed either before or after they were given the normative information. The results indicated that activation of a pro-prejudice injunctive norm for those higher in homophobia resulted in more prejudiced opinions being expressed in comparison to those who received no normative information or those who had a nonprejudiced norm activated. Those lower in homophobia expressed less prejudiced opinions than those higher in homophobia and this did not differ as a function of social norm. The results demonstrate how prejudice can come to be expressed even in the presence of a broad societal norm that suggests that is it wrong to express such opinions.

Perceived dissimilarity and work group involvement: The moderating effects of group openness to diversity

Perceived dissimilarity and its association with work group involvement were examined in this study. Additionally, perceived group openness to diversity was examined as a moderator of this relationship. A longitudinal study was conducted with nurses in four departments of a public hospital. Results revealed that visible dissimilarity was negatively associated with work group involvement at both times, and informational dissimilarity was negatively associated with work group involvement at Time 1. Openness to diversity interacted with visible and informational dissimilarity in the prediction of work group involvement at both times. This interaction pattern showed that there was a negative relationship between dissimilarity and work group involvement when individuals perceived low group openness to diversity, whereas there was no relationship when individuals perceived high group openness to diversity. Results highlight the importance of managing perceptions of difference and introducing norms that encourage the active involvement of group members.

Greene Climacteric Scale: norms in an Australian population in relation to age and menopausal status

Objectives The aim of this study was two-fold: to assess climacteric symptoms and provide normative data for the Greene Climacteric Scale during the menopause transition, and to investigate the prevalence of climacteric symptoms in a representative sample of postmenopausal Australian women. Method A cohort of 500 premenopausal, perimenopausal and postmenopausal women aged 40-80 years participated in the Longitudinal Study of Ageing in Women (LAW study) at the Royal Brisbane and Women's Hospital, Brisbane, Australia. In year 1 of the study (2001), all participants completed the Greene Climacteric Scale and information regarding their menopausal status and the use of hormone therapy (HT) was obtained through a clinical interview with a qualified medical practitioner. Results The 50-59-year age group achieved the highest scores on the vasomotor and the depression scales in comparison to other age groups. Significant differences were also evident on the vasomotor and the depression scales on the basis of menopausal status, especially in perimenopausal women. Approximately 10% of women in the 60-79-year age group continued to experience vasomotor symptoms. Conclusion Vasomotor symptoms, as assessed by the Greene Climacteric Scale, are common during the menopause transition and remain elevated for some years in a minority of older postmenopausal women. The norms presented in this study are appropriate for use in an Australian population.

When group members admit to being conformist: The role of relative intragroup status in conformity self-reports

Five studies examined the hypothesis that people will strategically portray the self as being more g-roup influenced the more junior they feel within the group. Among social psychologists (Study 1), ratings of self-conformity by g-roup members were greater when the status of the participant was low than when it was high. These effects were replicated in Studies 2, 3, and 4 in which relative intragroup status was manipulated. In Study 3, the authors found junior group members described themselves as more conformist than senior members when they were addressing an ingroup audience, but when they were addressing an outgroup audience the effect disappeared. Furthermore, junior members (but not senior members) rated themselves as more conformist when they were led to believe their responses were public than when responses were private (Study 5). The discussion focuses on the strategic processes underlying low-status group members' self-reports of group influence and the functional role of conformity in groups.

Motivations for group membership: The role of subjective importance and uncertainty reduction

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 cost of sin:the effect of social norms on audit pricing

In this paper we provide evidence for the effects of social norms on audit pricing by studying companies belonging to the alcohol, firearms, gambling, military, nuclear power, and tobacco industries,which are often described as “sin” companies. We hypothesize that the disparities between “sin” firms operations and prevailing social norms create an adverse context which heightens the client's business risk assessment by auditors and is, thereby, reflected in the pricing decisions for audit and consulting services. Having controlled for the impact of variables relating to client attributes, auditor attributes and engagement attributes, we demonstrate that audit firms charge significantly higher audit and consulting fees to companies that deviate from prevailing social norms. Additionally,we show that audit pricing levels within the “sin” group depend both on prevailing political views and on the level of “vice” exhibited by “sin” companies.
