在中国古代经典梦意象当中,彩笔梦是影响非常深远的一个.自从江淹梦得彩笔文思大涨之后,历代文人常有此梦载录,并衍生出诸如"彩色笔梦"、"砚梦"等同一性质的梦意象来.彩笔梦之所以如此盛行,是因为其与文章、功名的密切关系.从这个角度上来说,彩笔梦蕴藏着中国古代文人对于自身文学成就的渴望."彩笔梦"中的彩笔之所以具有如此重要的神性,与弗雷泽所描述的"金枝"有着异曲同工之妙,都是"触染率"的典型表现. 相似文献

We performed a multilevel, multinational analysis of the 2014 European Social Survey dataset (N = 33,597, nested in 19 countries) to study how individual conservative values and cultural embeddedness moderate the link between contact with immigrants and the attitudes toward them. A combination of frequency and positivity of contact with immigrants showed a negative association with ethnic prejudice while, conversely, participants’ conservative basic values were directly and positively associated with prejudice. National cultural embeddedness was not associated with the dependent variable. Neither individual conservative values nor cultural embeddedness moderated the association between contact and prejudice. Strengths, limitations, implications and future directions of this study are discussed. 相似文献

The prejudice-reducing effects of intergroup contact have been well documented. However few studies have investigated the importance of the broader context within which contact occurs. The current study examined the predictors of social distance from Muslims in a large sample of Australian secondary school children (N = 980). Intergroup contact was an important predictor of reduced social distance even after demographics and perceptions of parents, school, media and broader intergroup dynamics were taken into account. However, in part the contact–social distance relationship was mediated by perceived parental support for intergroup relations and perceived fairness of media representation. Student's perceptions of broader group dynamics relating to collective threat and differentiation between groups impeded the relationship. The findings attest to the importance of the broader context within which contact occurs. Having contact with outgroup members leads to reduced social distance to the outgroup, however perceived norms and outgroup perceptions play a pivotal role in explaining this relationship. 相似文献

Opportunities for intergroup contact are particularly important for prospective teachers because they bear responsibility for an ethnically diverse student population. Using data from a sample of 330 students inscribed in Austrian university colleges of teacher education, we investigated the long-term effects of international student exchange on prospective teachers’ motivation to avoid prejudiced behavior (MAPB). Both sojourning and domestic students’ friendships with visiting international students (VIS) were evaluated as potential instances of naturally occurring intergroup contact that can affect students’ MAPB. Sojourning students had an increased MAPB even nine months after returning to their home country. No effect was found for domestic students’ friendships with VIS. Possibly, the quality of these friendships was insufficient to result in long-term prejudice reduction. Implications of these results are discussed, and the need to advance interventions that are appropriate to improve domestic students’ contact with VIS is ascertained. 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

Kinematic analysis is done by measurement of the position of bodies, followed by differentiation to get the accelerations
of the centres of mass, and it is widely used in sport research. Another common approach is to measure the forces directly.
Our intention here is to perform both a kinematic and a kinetic analysis of the same athlete-equipment system, in this case
an athlete on a sliding kayak ergometer, with the aim of exploring the errors that may occur with each measurement type. The
kayak ergometer with a sliding trolley, instrumented by seven uniaxial force sensors and two goniometers, was placed in a
filming area. The instrumentation was validated in the direction of the anteroposterior axis using Newton’s second law. Ten
athletes paddled at 92 strokes per minute, following a stationary phase. The comparison between the net force and the time-derivative
of the linear momentum indicated a friction level of about 20 N between the trolley and the frame. Other errors came mainly
from the inertial parameters of the trunk. A first analysis of contact forces shows a large inter-subject variability, in
particular for the forces applied to the footrest and the seat. 相似文献

Prior studies have found that normative group pressure plays a significant role in shaping prejudice-related attitudes. The present paper examined the role of perceived group norms on the indirect relationship between intergroup contact and anti-Muslim prejudice in a cross-sectional sample of 428 non-Hispanic White American adults, the racial group with the strongest anti-Muslim sentiment. To begin, we tested the indirect relationship between intergroup contact and anti-Muslim prejudice via perceived realistic and symbolic threats as well as intergroup anxiety. Next, we tested whether these mediation effects were conditional on whether group norms were perceived as tolerant or intolerant. We employed Process Macro to test these hypotheses. Our data confirmed (partial) mediation of the contact-prejudice relationship via threat perceptions and intergroup anxiety. Moreover, the moderated mediation analysis showed that while the mediation effects of threat perceptions were not conditional on perceived group norms, the mediation effect of intergroup anxiety was. Specifically, for respondents with perceived intolerant norms, negative intergroup contact demonstrated a stronger relationship with anti-Muslim prejudice through intergroup anxiety compared to respondents with perceived tolerant norms. Furthermore, given the possible bidirectionality of the contact-prejudice relationship, we tested an alternative model examining whether perceived intolerant norms mediate the effect of prejudice on contact. Our data supported this hypothesis, fitting a model that prejudice creates the intolerant group norms that in turn leads to negative contact with Muslims. The alternative model in fact showed a better fit to the data than the proposed model. This study advances theories of contact, integrated threats, and group norm theory to the context of intergroup relations with Muslims. Our findings provide support for the notion of changing the normative climate, and equally promoting positive intergroup contact, with the goal of enhancing relations between Muslim and non-Muslim individuals. 相似文献

Objective
This study investigated the effect of proximal contact strength on the three-dimensional displacements of cantilever fixed partial denture (CFPD) under vertically concentrated loading with digital laser speckle (DLS) technique.Methods
Fresh mandible of beagle dog was used to establish the implant-supported CFPD for specimen. DLS technique was employed for measuring the three-dimensional displacement of the prosthesis under vertically concentrated loading ranging from 200 to 3 000 g. The effect of the contact tightness on the displacement of CFPD was investigated by means of changing the contact tightness.Results
When an axial concentrated loading was exerted on the pontic of the implant-supported CFPD, the displacement of the CFPD was the greatest. The displacement of the prosthesis decreased with the increase of contact strength. When the contact strength was 0, 0.95, and 3.25 N, the displacement of the buccolingual direction was smaller than that of the mesiodistal direction but greater than that of the occlusogingival direction. When the force on the contact area was 6.50 N, the mesiodistal displacement of the prosthesis was the biggest while the buccolingual displacement was the smallest.Conclusions
The implant-supported CFPD is an effective therapy for fully or partially edentulous patients. The restoration of the contact area and the selection of the appropriate contact strength can reduce the displacement of the CFPD, and get a better stress distribution. The most appropriate force value is 3.25 N in this study. 相似文献90.
