The association between in-class cultural diversity with empathy and bullying in adolescence: A multilevel mediation analysis

Little is known about the associations between cultural class composition, teacher support for diversity (TSD), cognitive and affective empathy, and bullying and victimisation. Research shows that empathy is negatively associated with bullying and victimisation; and support for diversity and classroom cultural diversity are positively linked to social skills. The present study examines whether cultural diversity and perceived TSD are protective factors against bullying and victimisation, either directly or mediated by empathy. Participants were 897 students from Grades 7 to 10 (M_age = 13.45, SD_age = 1.07, 51.3% girls, 46.7% boys) in 36 classes. Multilevel mediation analyses were conducted. Age and gender were controlled for. More perceived TSD and affective empathy were associated with less bullying. Moreover, the effect of perceived TSD on bullying was partly indirect through affective empathy. Victimisation was not predicted by the study variables. The class level showed no effects. Bullying and victimisation are complex phenomena, which seem to be linked more to individual than to class characteristics. The result that higher perceived TSD was linked to empathy and bullying provides a promising starting point for measures of competence enhancement and bullying prevention.     

The Role of Social Network Structure in the Emergence of Linguistic Structure

Social network structure has been argued to shape the structure of languages, as well as affect the spread of innovations and the formation of conventions in the community. Specifically, theoretical and computational models of language change predict that sparsely connected communities develop more systematic languages, while tightly knit communities can maintain high levels of linguistic complexity and variability. However, the role of social network structure in the cultural evolution of languages has never been tested experimentally. Here, we present results from a behavioral group communication study, in which we examined the formation of new languages created in the lab by micro-societies that varied in their network structure. We contrasted three types of social networks: fully connected, small-world, and scale-free. We examined the artificial languages created by these different networks with respect to their linguistic structure, communicative success, stability, and convergence. Results did not reveal any effect of network structure for any measure, with all languages becoming similarly more systematic, more accurate, more stable, and more shared over time. At the same time, small-world networks showed the greatest variation in their convergence, stabilization, and emerging structure patterns, indicating that network structure can influence the community's susceptibility to random linguistic changes (i.e., drift).     

农民工社会认知状况的调查研究

本研究以465名农民工为被试,采用有较高信、效度的自编农民工社会认知状况调查问卷,考查农民工打工生活和城市融入的社会认知状况.结果发现:(1)农民工的整体社会认知状况尚可,平均得分高于3分临界值;(2)不同年龄、婚姻、学历,打工次数、打工时间的农民工的社会认知差异显著.年龄较大的、已婚的、学历较低的、有过多次打工经历的和打工时间较长的农民工社会认知更好;新生代农民工较第一代农民工社会认知低,呈明显的代际特征;(3)收入较高和从事职业较好的农民工社会认知得分更高,即收入与职业影响农民工的社会认知.     

幽门螺杆菌cagA基因多态性对临床结局的影响：东亚菌株和西方菌株

CagA蛋白是幽门螺杆菌最重要的毒力因子之一。目前已证实cagA基因存在东亚及西方两种亚型。幽门螺杆菌产生CagA蛋白,注入胃上皮细胞后在其羧基端EPIYA重复序列区进行酪氨酸磷酸化,进而与SHP-2酪氨酸磷酸化酶相互作用,参与上皮细胞的信号传导,导致细胞骨架结构的重排,引起细胞表面形状的改变和细胞动力的增强,造成细胞异常的增殖和运动,在胃癌的发生中起了主要作用。cagA基因的羧基端EPIYA重复序列被认为是区分东亚型和西方型菌株的分子标记,东亚型CagA与SHP-2亲和力大于西方型,最终影响着不同CagA 菌株感染的临床表现。     

自我验证与人际一致性：团队多样性利用的新视角

全球化背景下组织构成正日趋多样化, 有效利用团队多样性的价值是组织成功的关键。以往的研究基于自我类化理论认为消除多样性负面效应的方法是追求高阶的群体认同。本文采用自我验证的视角, 提出团队成员的个人自我认知和社会自我认知得到他人验证能够促进人际一致性, 增强个体对群体的情感联结, 并可以最大化地发挥多样性的正面效应, 提升决策质量和团队效能。此外, 当团队分裂为小团体、联盟体和共同体等三种不同的亚群体类型时, 自我验证过程将呈现出不同的动态, 团队领导者需要采取针对性的领导方式来帮助成员获得自我验证的信息。     

Cultural diversity,migration and education

Migration is not a new phenomenon. However, recent data indicate that unprecedented numbers of people have experienced forced migration around the world with 51% under the age of 18 years. How can educational policies and practices respond sensitively to increasing cultural and migration-based diversity? The purpose of this special section that includes eight studies is to consider these issues more deeply. As a frame for the special section, we address the main question: What are promotive or protective factors for positive development of children and youth attending culturally diverse school contexts? In the collection of papers, these promotive and protective factors range from peers and families, to teachers, to organisational context and climate. With continued disruptions in children's lives due to a pandemic, climate change, war, conflict and poverty, migration will remain a pressing concern and will continue to transform the student populations in our classrooms and schools for the foreseeable future. The need to address how we can best provide students from diverse backgrounds equitable and supportive education, continues.     

Peer Victimization in School: Exploring the Ethnic Context

ABSTRACT— This article provides an overview of recent research on peer victimization in school that highlights the role of the ethnic context—specifically, classrooms' and schools' ethnic composition. Two important findings emerge from this research. First, greater ethnic diversity in classrooms and schools reduces students' feelings of victimization and vulnerability, because there is more balance of power among different ethnic groups. Second, in nondiverse classrooms where one ethnic group enjoys a numerical majority, victimized students who are members of the ethnic group that is in the majority may be particularly vulnerable to self-blaming attributions. The usefulness of attribution theory as a conceptual framework and ethnicity as a context variable in studies of peer victimization are discussed.
