The present study investigated whether the associations of positive and negative intergroup contact with behavioral intentions (intentions to have contact with the outgroup in the future) are moderated by social dominance orientation (SDO), by considering the perspective of both majority and minority group members in China. Participants were 325 Han (majority) and 373 Uyghur (minority) members, who completed a self-report questionnaire. Results indicated that positive contact was associated with more positive behavioral intentions among high-SDO majority group members, whereas SDO did not moderate the association between positive contact and behavioral intentions among minority group members. In addition, negative contact was associated with lower behavioral intentions among high-SDO majority group members, and among low-SDO minority group members. This study suggests that attention should be placed simultaneously on positive and negative contact and on individual difference variables relevant to social ideologies, such as SDO. 相似文献

The dynamic contact resistances of HH52P electromagnetic relays are measured under different ambient air tem- perature. Their diagnostic parameters are extracted and determined. It is found that the ambient air temperature obviously influ- ences some parameters. In order to research its influence on the electrical contact reliability of electromagnetic relay, the statistic analysis is applied to study the static contact resistance, the max of the dynamic contact resistance and the bounce time. It is found that the ambient air temperature regularly influences the three parameters. Thoroughly, the phenomenon is studied and analyzed in the point of material science so as to probe into the essential matter of it. 相似文献

Canada announced a policy of multiculturalism in 1971. The goal of the policy was to improve the quality of intercultural relations. Two main elements of the policy were proposed as steps towards achieving this goal: support for the maintenance and development of cultural communities (the cultural component); and promotion of intercultural contact along with the reduction of barriers to such participation (the intercultural component). Research on these issues can provide a basis for the development and implementation of multiculturalism policies and programmes. A review of psychological research on multiculturalism over the past 40 years is summarised. Topics include: knowledge about the multiculturalism policy; acceptance of multiculturalism; acceptance of ethnocultural groups; acceptance of immigrants; discrimination and exclusion; and attachment and identity. Research assessing three hypotheses derived from the policy is also briefly reviewed. Current evidence is that there is widespread support for these features of the multicultural way of living in Canada. Of particular importance for the success of multiculturalism is the issue of social cohesion: is the first component (the promotion of cultural diversity) compatible with the second component (the full and equitable participation and inclusion of all ethnocultural groups in civic society)? If they are compatible, together do they lead to the attainment of the fundamental goal of attaining positive intercultural relations? Current psychological evidence suggests that these two components are indeed compatible, and that when present, they are associated with mutual acceptance among ethnocultural groups in Canada. I conclude that research in Canada supports the continuation of the multiculturalism policy and programmes that are intended to improve intercultural relations. 相似文献

Based on the tenets of the social context model of second language acquisition, the present article examined the combined effect of online and face-to-face contact in developing multilingual skills and identities among young Swedish-speaking Finns (N = 304). The hypotheses were tested for Finnish as a second language and English as a third language using parallel models. The results were largely identical for both languages. Specifically, online contact enhanced language confidence which, in turn, contributed to language identity. However, online contact had a more substantial effect on confidence as well as identity among those who had little face-to-face contact with speakers of the given language. Findings and their implications are discussed. 相似文献

类比推理与比喻推理在概念、推理模式、特征以及作用等方面既有区别又有联系。类比推理建立在客观事实的基础上,常用于探索自然界的奥秘,它要求两个(类)事物有一系列相同之处,已知属性与推出属性的相关程度越高,前提对结论的支持就会越强;而比喻推理建立在比喻这种修辞手法之上,常用于论述道理,比喻推理中比喻和被比喻的事物只要存在相似关系即可,相似属性的建立越恰当精准,推理越\"有说服力\"。但类比推理和比喻推理都是对两个(类)不同事物进行比较,要求事物间相似处越多越好,并且力求产生较强推理效果的推理。 相似文献

We explored whether mediated intergroup contact might stimulate other forms of intergroup contact. Our study compared two forms of mediated contact: vicarious intergroup contact (exposure to an intergroup relationship) and parasocial contact (exposure to just outgroup members) in terms of their potential to stimulate spontaneous imagined intergroup contact. We also examined whether that spontaneous imagined contact would increase desire for face-to-face contact. Results showed that vicarious contact elicited more imagined contact when the media stimulus was low in richness. A path model from vicarious contact to face-to-face contact via imagined contact was supported, however the direction of effects was the opposite of our hypothesis. The more participants engaged in imagined contact with outgroup members in which group memberships were salient, the less they wanted to meet outgroup members in person. We speculate that the surprising effects are a result of the potential for our experimental stimuli to encourage group salient, and therefore negative imagined contact. However, our work demonstrates the ability for mediated contact to trigger spontaneous imagined contact, and some positive links between (non-outgroup-specific) imagined contact and increased desire for intergroup contact. 相似文献

Investigation on the factors influencing the thickness distribution of superplastic-formed components 总被引:1,自引:0,他引:1
In the superplastic sheet forming process, the uniformity of the sheet's final thickness distribution is vital for ensuring the good mechanical quality of the formed components. The influences of the component shape and the contact friction on the final thickness distribution were investigated in this work by using finite element method on a series of axisymmetric models. It was concluded that shape optimization and friction elimination are required to get uniform thickness distribution, and eventually to improve the mechanical quality of the formed components. The constitutive equation of the Ti-6Al-4V superplastic material was also determined on the basis of experimental data. 相似文献
