This study examined racial–ethnic minority and white identified participants’ perceptions of racial microaggressions in four video scenarios involving a white professor and a black student. Participants (N = 261) were randomly assigned to observe a one of the four video conditions. The video involved an interaction with no microaggression, a very ambiguous microaggression, an ambiguous microaggression, or an overt microaggression. Participants rated their observations of (a) negative emotions toward the committer (white professor) and receiver (black student) of the microaggression, (b) positive emotions toward the committer and receiver of the microaggression, (c) perceptions on the degree of biasedness of committer, and (d) degree of positive perceptions of the committer. Analysis compared ratings of two groups, including racial–ethnic minority and white observers. We found a significant difference between the overt condition and other three conditions on negative emotions, positive emotions, and attributions of the professor (i.e., cultural biasedness and positive perceptions). However, there were no differences between the no microaggression, very ambiguous, and ambiguous conditions. No significant differences between racial–ethnic minority and white participants’ ratings were detected. Implications for training, practice, and future research are offered in our discussion. 相似文献

In order to make feedback as effective as possible, it is important to understand its function in the three-term contingency (TTC) and the impact of various factors involved in delivering feedback. Timing of feedback is one factor that can affect the impact of feedback on learner’s behavior. An analysis of timing of feeback may help us getting closer to better understanding how feedback functions in the TTC. The purpose of this study was to evaluate the effects of feedback at different temporal locations. Specifically, feedback was provided either immediately (a) after a teaching session or (b) before the following teaching session, on teaching performance of undergraduate psychology students. The results indicated that feedback provided before the teaching session was more effective in improving teaching skills than feedback that was provided after the session. These findings suggest that feedback may function primarily as an antecedent to future performance and not necessarily as a consequence for past performance. However, the behavioral mechanism that explains these results is not yet clear. Future studies should investigate this further by manipulating the content of feedback prior to the teaching performance. 相似文献

ABSTRACTThis paper analyses the interrelationship between patterns of im/mobility on the one hand and the reconstitution of social collective identities and the related emergence or settlement of conflicts on the other. The main arguments are (1) that the im/mobility of a social or cultural group has major impact on how identity narratives, a sense of belonging and relationships to ‘others’ are shaped, and vice versa, and (2) that these dynamics are closely interlinked with mechanisms of inclusion and exclusion between groups and power structures that involve a broad variety of actors. Mainly looking at patterns of internal mobility such as ‘traditional’ or strategic mobilities and mobilities enforced by crisis, conflict or governmental programmes and regimes, the contribution provides the conceptual background for a special issue that aims to go beyond currently predominant issues of transnational migration. Established or emerging dynamics of (non-)integration and belonging, caused by im/mobility, are analysed on a cultural and political level, which involves questions of representation, indigeneity/autochthony, political rights and access to land and other resources. Conflict situations in contexts of mobility involve changes in the social understanding and renegotiation, reconstruction or reproduction of group identities and narratives with reference to certain socio-political and historical patterns. The legitimation of rights and access to various forms of citizenship and mobility need to be understood against the backdrop of emerging or established mechanisms of inclusion and exclusion between groups, which trigger or settle conflicts and make social identities to be constantly renegotiated. 相似文献

ABSTRACTIn recent years, Sierra Leone has witnessed intense population movements. During the civil war (1991–2002), many populations fled the fighting zones of the interior to take refuge on the coast. Since the conflict ended, new populations have reached the coastal area with the hope of accessing economic opportunities in the fishing business. Mobility, along with changing sociopolitical and economic conditions, has generated conflict between immigrants and Sherbro populations, who consider themselves autochthonous and deny migrants the freedom to access political and land rights. The paper argues that present dynamics of conflicts are rooted in long-term patterns of settlement and relationships of reciprocity between groups. Relations between migrants and local populations are grounded in a sociocultural idiom that implies the institutionalization of practices of reciprocity between local inhabitants (hosts) and later settlers (strangers). The host/stranger reciprocity system is an emic model of cultural action embedded in historical and power relations between groups. It implies the progressive integration of strangers into the host society. This paper highlights how, in a situation of conflict, long-established social relationships between groups are reevaluated with reference to norms of integration and reciprocity. The paper draws on Sherbro oral traditions to show how social memories about interethnic relations are reframed with reference to values and expectations of reciprocity, in order to explain the recent conflict that opposes Sherbros to immigrants. Sherbros use oral traditions to interpret these tensions in a long-term perspective, thereby expressing their own view on settlement, conflict and integration. 相似文献

In several areas like global optimization using branch-and-bound methods for mixture design, the unit n-simplex is refined by longest edge bisection (LEB). This process provides a binary search tree. For \(n>2\), simplices appearing during the refinement process can have more than one longest edge (LE). The size of the resulting binary tree depends on the specific sequence of bisected longest edges. The questions are how to calculate the size of one of the smallest binary trees generated by LEB and how to find the corresponding sequence of LEs to bisect, which can be represented by a set of LE indices. Algorithms answering these questions are presented here. We focus on sets of LE indices that are repeated at a level of the binary tree. A set of LEs was presented in Aparicio et al. (Informatica 26(1):17–32, 2015), for \(n=3\). An additional question is whether this set is the best one under the so-called \(m_k\)-valid condition. 相似文献

It is generally difficult to separate the effects of divorce from selection when analyzing the effects of parental divorce on children’s risk behaviors. We used propensity score matching and longitudinal data methods to estimate the effects of parents’ divorce on their children’s binge drinking, alcohol consumption, tobacco use, marijuana use, and hard drug use. The children were between 12 and 18 years old in the first survey and between 18 and 24 years old in the second survey. Our results suggest that parental divorce significantly increased the probability of risk behaviors in their children. Moreover, many of these adverse impacts persisted over time, especially among teenage girls. 相似文献

Persons referred by Child Protective Services (CPS) for substance abuse evidence high rates of nonattendance to therapy sessions, taxing systems of care and exacerbating outcomes. This study examined the influence of two telephone-based incentive programs on therapy session attendance in mothers who were referred by CPS for substance abuse. After baseline therapy session attendance was established in an evidence-based clinic that incorporated a telephone engagement intervention (Phase I), participants were provided free cellular telephones with limited minutes and permitted to order free meals delivered by the therapist during upcoming sessions (Phase II). The third phase was similar to Phase II, but participants were provided unlimited minutes. Results indicated that participants’ attendance was significantly improved when meals and cellular telephone minutes were contingent on attendance. Although the percentage of sessions attended by participants during Phase III was higher than Phase II, unlimited minutes and meals did not significantly enhance attendance relative to limited minutes and meals. Session attendance for significant others of these participants was significantly higher during Phase III as compared with Phase I. Session attendance of significant others was statistically similar between Phase I and II and between Phase II and Phase III. Study implications and recommendations for future research and practice are discussed in light of the findings. 相似文献

ABSTRACTFor all youth, adolescence is a time of great change, marked by multiple transitions. For those with disabilities, these transitions can be especially challenging for the youth and their families. Although families of adolescents with disabilities often require support, it is unclear what types of assistance are most helpful. To understand the responsibilities of and, correspondingly, supports needed for parents and siblings, the authors conducted a comprehensive literature review. Specifically, the authors examined the literature to identify the supports that families provide to their adolescent relatives with disabilities, the impacts of caring for an adolescent relative with a disability, and the assistance that families receive. The authors conclude by discussing implications for future research about family support. 相似文献
