An Examination of the Effects of Mediated Intragroup and Intergroup Interactions among Latino/a Characters

Content analytic work has consistently shown that Latinas are consistently found to be one of the most sexualized social groups in the media. In this study we experimentally examined the implications of exposure to the sexualized depiction of Latinas (among non-Latino viewers), when presented in the media in a within group context (Latina-Latino portrayal) and an intergroup context (Latina-White male portrayal). Findings suggest that when in an intergroup interaction, sexualized Latinas are evaluated more favorably and elicit less negative emotion than sexualized Latinas in an intragroup interaction. Implications are discussed within the context of mediated intergroup contact and intergroup emotion.     

A test of anxiety/uncertainty management theory: The intercultural adaptation context

Anxiety/Uncertainty Management theory, as formulated by Gudykunst and Hammer (1987a), proposes that intercultural adaptation outcomes are based on the two mediating dimensions of uncertainty reduction and anxiety reduction and sixteen secondary variables that systematically influence uncertainty and anxiety reduction. In this paper, the sixteen variables originally identified are categorized into four “fundamental factors”; (interpersonal saliencies, intergroup saliencies, communication message exchange, and host contact conditions). The present study examines this revised Anxiety/Uncertainty Management (AUM) theory of intercultural adaptation. A total of 291 international students at two universities in the United States participated in the study. The study found overall fit of the revised AUM theory vis‐a‐vis the two mediating factors of uncertainty and anxiety reduction, the importance of interpersonal saliencies for uncertainty reduction, and the importance of host contact conditions for facilitating feelings of comfort and reducing anxiety. Intergroup saliencies were significantly related to uncertainty reduction but not, contrary to expectation, to anxiety reduction. Communication message exchange (which consists of information gathering strategies and second language proficiency) was, again contrary to expectation, not significantly related to either uncertainty or anxiety reduction. Finally, cultural identity showed a small though significant negative relationship to intergroup saliencies, suggesting a stronger, ingroup identity was associated with increased uncertainty. The paper concludes by proffering explanations for the findings and suggestions for future research.     

The influence of intercultural communication apprehension and socio‐communicative orientation on uncertainty reduction during initial cross‐cultural interaction

This study is an investigation of the influence of intercultural communication apprehension, socio‐communicative orientation, and uncertainty during initial cross‐cultural communication. Prior to interacting with unknown partners from another culture, participants completed measures of intercultural communication apprehension and socio‐communicative orientation. After interacting with their partners, participants completed measures of uncertainty. As predicted, intercultural communication apprehension was positively associated with uncertainty. Also as predicted intercultural communication apprehension was negatively correlated with socio‐communicative orientation. A third hypothesis, which was partially supported, posited that socio‐communicative orientation would be negatively correlated with uncertainty.     

Predicting student success in open and distance learning

This paper reviews some of the ways in which student success can be predicted in conventional and distance education. Predicting such success is particularly important for new students where the pre‐course start information available is sometimes slight and withdrawal often occurs very early in a course. It suggests that, in such cases, statistical methods involving logistic regression analysis are more useful than questionnaires or tutors’ opinions. Identifying students with low probability of success allows support to be targeted on them. However, there are ethical dilemmas to do with targeting support and openness with students about the results of any analysis.     

Is ‘Closing the Gap’ Enough? Ngarrindjeri ontologies,reconciliation and caring for country

This article is concerned with Ngarrindjeri nation building in the ‘contact zone’ with the Australian settler state by decentring the colonizer within a range of bureaucratic regimes. Ngarrindjeri engagement with natural resource and cultural heritage management will be used to illustrate the relationship between globalization, community governance, education, sustaining ‘culture’, Indigenous well-being, and reconciliation and its links to the Australian government Closing the Gap initiatives. This article connects Ngarrindjeri lived experience to the theorization of processes for self-recovery and social transformation that open possibilities for broad-based local and global coalitions, which include political solidarity in the interests of just Indigenous ‘reinhabitation’ and decolonization.     

Utopian totalism versus utopian realism: a reply to Darren Webb

Debate continues about the relationship between schools divided on ethno-religious lines and their implications for social cohesion. One argument against the existence of separate schools is that they limit opportunities for children from different groups to engage with each other, promoting intergroup suspicion and sectarianism. Using intergroup contact theory we examine the impact on outgroup attitudes of pupils attending mixed and separate post-primary schools in Northern Ireland. Data were collected through a survey of more than 3,500 pupils and analyses show that, irrespective of school type, intergroup contact at school is strongly associated with more positive orientations to the ethno-religious outgroup. The policy implications of these findings are discussed.     

聚苯乙烯微球的AFM研究

采用接触式原子力显微镜（AFM）方法观测聚苯乙烯微球用去离子水和甲醇分散后在云母表面的形貌变化及与衬底之间的作用;初步讨论了分散剂、放置时间、分散时间等对聚苯乙烯微球的影响。结果发现去离子水做为分散剂时,聚苯乙烯微球在云母表面具有单分散性,而以甲醇做为分散剂时则具有多分散性。     

"双核"经济中心理论下的京津冀城市群发展设想

在城市群的发展过程当中,我们日益面临类似于计算机科学发展过程中曾经面临的问题。比如,在计算机中,双核架构有效解决了单核架构的瓶颈制约,而在城市群中尤其是在京津冀城市群中,单极经济中心发展战略正面临诸多无法克服的硬性约束。为此,本文提出了"双核"经济中心的架构,并认为"双核"经济中心是资源靶向性、规模经济及有机疏散理论的内在要求。在此基础上,本文进一步分析了京津冀城市群实行"双核"经济中心的基础及必要性。最后,在借鉴计算机双核之间联系和分工机制的基础上,提出了城市群"双核"之间的联系和分工机制,力求对城市群尤其是京津冀城市群提供一定的理论和实施策略指导。     

城市对外经济联系量与地缘经济关系的匹配分析——以南京市为例

在城市或区域规划研究中,常分别通过城市对外经济联系量、欧氏距离法测算城市或区域之间的联系强度、竞争与合作关系。本文尝试开展两者的协同研究,以南京市为例,通过测算其与不同城市之间的对外经济联系量、地缘经济关系及其匹配关系,为南京市城市或区域规划提供决策支撑,为今后开展类似研究提供研究思路和方法框架。
