Identity and attitudinal reactions to perceptions of inter-group interactions among ethnic migrants: a longitudinal study

This 1-year follow-up study investigated the direct and indirect effects of past, anticipated, and actual experiences of inter-group interactions on the development of national identity and attitudes towards the national majority among ethnic re-migrants (N= 141) from Russia to Finland. According to the results, the quality of past inter-group contact in the pre-migration stage (T(1)) did not directly affect national identification and out-group attitudes in the post-migration stage (T(2)). Instead, the effect of contact quality at T(1) on national identification and out-group attitudes at T(2) was indirect via perceived discrimination and out-group rejection at T(2). In addition, there were two indirect pathways from out-group attitudes at T(1) to national identification and out-group attitudes at T(2), via pleasant contact experiences (further associated with positive out-group attitudes) and via perceived discrimination (further associated with negative attitudes and lower national identification) in the post-migration stage. Anticipated discrimination only had a direct effect on out-group attitudes in the post-migration stage. The results highlight the role of past and anticipated inter-group relations in the formation of post-migration inter-group interactions, which, in turn, are decisive for the formation of national identification and out-group attitudes of re-migrants.     

Comparison of corticosterone responses to acute stressors: Chronic jugular vein versus trunk blood samples in mice

A commonly used method for obtaining blood samples from mice is decapitation. However, there is an obvious need for repeated blood sampling in mice under stress-free conditions. Here, we describe a simple technique to repeatedly collect blood samples from conscious, freely moving mice through a chronically implanted jugular vein catheter. Furthermore, we compare plasma corticosterone (CORT) concentrations in samples obtained through the catheter 1 day after surgery with samples taken from trunk blood obtained under basal or acute stress conditions. CORT concentrations in repeated 100-μl venous blood samples were found to be similar to trunk blood samples both under basal conditions and after stressor exposure collected at identical time points (at 5, 15, and 60?min). Using both techniques, we demonstrate a progressive increase in CORT levels until 15?min after termination of stressor exposure and a decrease towards baseline values 60?min later. Anxiety-related behavior, as assessed on the elevated plus maze 3-4 days after surgery, did not differ between catheterized and non-catheterized mice. Our results provide evidence for application of jugular vein catheterization as a technique for repeated blood sampling in conscious laboratory mice. Use of this technique will greatly reduce the number of animals required for experiments involving endocrine endpoints.     

Body image trends among Icelandic adolescents: a cross-sectional national study from 1997 to 2010

The aim of this study was to evaluate trends in body image among Icelandic adolescents from 1997 to 2010. Data from five cross-sectional surveys conducted among national samples of 9th and 10th graders in Iceland using five time points (1997, 2000, 2006, 2009, and 2010) were compared to examine changes in body image. In total, 32,397 adolescents participated in the study. Body image among 14-15-year-old adolescents in Iceland improved significantly over the 13-year period. Girls reported more negative body image than boys at all time points. However, the positive change in body image from 1997 to 2010 was more pronounced for girls than boys, resulting in a narrower gap between the genders. The current results are encouraging and indicate that in an age of increased overweight and obesity, the body image of Icelandic adolescents is becoming more positive.     

Teaching Exegesis in Historically Black Theological Schools

This Forum collects the papers presented at a 2010 panel at the Society of Biblical Literature, an outcome of a Wabash Center funded grant project. The project examined the unique dimensions and experiences of teaching Biblical exegesis at the six historically black theological schools (HBTSs), including discussion of the unique needs of HBTS students and their communities, and appropriate learning goals and effective teaching practices for this context. None of the biblical studies faculty were prepared as graduate students for the unique challenges that they have encountered teaching at a HBTS, so they have all had to “learn on the job” how best to approach the unique needs of the student body. The brief statements collected here summarize the findings from the project, describe and analyze some effective teaching strategies, and offer suggestions for continuing the conversation.     

Perceived ethnic superiority and immigrants' attitudes towards multiculturalism and the national majority

Despite the recent multidimensional conceptualisations of social identities, previous research on the relationship between ingroup identification and outgroup attitudes has approached the former mainly through the strength of cognitive‐emotional identification. In our study among Russian‐speaking immigrants living in Finland (N = 312), we focused on the direct and interactive effects of the strength of ethnic identification and perceived ethnic superiority on immigrants' support for multiculturalism and outgroup attitudes towards national majority. First, we found perceived ethnic superiority to be directly and negatively associated with outgroup attitudes. Second, we found a positive relationship between ethnic identification and support for multiculturalism only when ethnic superiority was not perceived. The results highlight the different ramifications of high ethnic identification and perceived superiority and speak for the destructive attitudinal effects of the latter.     

The ironic effect of national identification on support for collective action

Previous research has suggested that dual and superordinate identities are not only prerequisites of collective action among minority group members but they can also be associated with greater acceptance of the ingroup's disadvantaged position. In this three‐wave study among Ingrian Finnish migrants from Russia to Finland (N=153_T1?85_T3), we tested the indirect association between superordinate national identification (T1) and support for collective action (T3), via perceived permeability of group boundaries (T2). Support for collective action was operationalized as one's personal willingness, and the perceived need of the Russian‐speaking community, to engage in it. When controlling for the direct association between Russian minority identification and support for collective action, perceived permeability was shown to mediate the negative association between Finnish national identification and support for community's collective action. Thus, being close to the majority may make immigrants perceive group boundaries as more permeable and be less inclined to improve their group's position.     

Semantic components in the literal and metaphorical use of movement verbs

The study analyzes acceptability judgments relating to sentences that have the same syntactic structure (subject-verb-locative) and varying possibilities of semantic anomaly. Twelve movement verbs were used—that is, 12 verbs indicating a change in position or location; a componential analysis of these verbs was carried out beforehand by the authors. In all, 288 sentences were constructed by combining these 12 verbs with 24 subject-locative pairs. The subjects (university students) were asked to judge the acceptability of the sentences on a 5-step scale. The data were subjected to two methods of factor analysis; in this way three factors were revealed. By examining the verbs loaded on the three factors in the light of the abovementioned componential analysis, it was found that certain components, if present, reduced the probability that a sentence would be judged acceptable in a metaphorical sense; this was especially true of the components use of instruments and typically human character of the action, which, in the sentences with nonhuman subject, are contradictory with the meaning of the subject, and of medium-specific, often contradictory with the meaning of the locative. The results are discussed in relation to some theoretical and methodological problems in current research on the comprehension of metaphor.
