Cyberbullying in High Schools: A Study of Students' Behaviors and Beliefs about This New Phenomenon

This study explores high school students' beliefs and behaviors associated with cyberbullying. Specifically, it examines this new phenomenon from the following four perspectives: (a) What happens after students are cyberbullied? (b) What do students do when witnessing cyberbullying? (c) Why do victims not report the incidents? and (d) What are students' opinions about cyberbullying? Data were collected from 269 Grade 7 through 12 students in 5 Canadian schools. Several themes have emerged from the analysis, which uncovers some important patterns. One finding is that over 40% would do nothing if they were cyberbullied, and only about 1 in 10 would inform adults. Students feel reluctant to report cyberbullying incidents to adults in schools for various reasons, which are discussed in depth.

城市社区现代化进程中的宗教问题

在加快城市社区现代化,缩小城市差距的重要历程中,人们在物质生活得到相应提升的同时日益追求更高层次的精神生活.因此,我们除了要在城市建设中为广大的群众提供更好的公共服务以及设备设施外,更需要关注广大人群的精神生活.宗教问题,就是一个客观存在也必须关注并需要解决的精神生活问题,它考量着各级政府的人文关怀精神,也考量着一个城市社区现代化的文明程度,对构建和谐城市社区具有重要意义.     

Age-related changes in memory and in acetylcholine functions in the hippocampus in the Ts65Dn mouse, a model of Down syndrome

Spatial working memory and the ability of a cholinesterase inhibitor to enhance memory were assessed at 4, 10, and 16 months of ages in control and Ts65Dn mice, a partial trisomy model of Down syndrome, with possibly significant relationships to Alzheimer's disease as well. In addition, ACh release during memory testing was measured in samples collected from the hippocampus using in vivo microdialysis at 4, 10, and 22-25 months of age. When tested on a four-arm spontaneous alternation task, the Ts65Dn mice exhibited impaired memory scores at both 4 and 10 months. At 16 months, control performance had declined toward that of the Ts65Dn mice and the difference in scores across genotypes was not significant. Physostigmine (50 microg/kg) fully reversed memory deficits in the Ts65Dn mice in the 4-month-old group but not in older mice. Ts65Dn and control mice exhibited comparable baseline levels of ACh release at all ages tested; these levels did not decline significantly across age in either genotype. ACh release increased significantly during alternation testing only in the young Ts65Dn and control mice. However, the increase in ACh release during alternation testing was significantly greater in control than Ts65Dn mice at this age. The controls exhibited a significant age-related decline in the testing-related increase in ACh release. With only a small increase during testing in young Ts65Dn mice, the age-related decline in responsiveness of ACh release to testing was not significant in these mice. Overall, these results suggest that diminished responsiveness of ACh release in the hippocampus to behavioral testing may contribute memory impairments in Ts65Dn mice.     

文化价值观是一种特殊货币形式

金钱是一种经人们约定的用来测量商品价值的独特测量工具。同样地, 文化价值也是能让人对自身价值做出一致评价的一种独特的测量工具。本文在综述有关研究的基础上提出一个观点：文化价值和金钱价值在人类的发展史上、神经机制、行为以及认知方面是重叠的。作者认为, 文化价值和货币都是基于类似的进化功能而产生的。其次, 当进行与社会价值观一致的活动(如捐赠和合作)时, 其行为所激活的脑区和获得金钱时所激活的脑区是相同的。同样地, 当进行违反社会价值观的活动(如欺骗和攻击)时, 其行为所激活的脑区和失去金钱所激活的脑区是相同的。第三, 相对于亲社会行为和获得金钱, 我们对社会背叛和失去金钱会更敏感(如厌恶损失)。第四, 全球化对金钱体系和价值体系的影响是相似的。     

社会判断内容的基本维度研究

社会判断在内容上存在热情与能力两个基本维度,前一个维度是对他人意图的反映,后一个维度是对他人能力的反映。首先对社会判断基本维度的命名进行剖析,接着梳理了社会判断中热情和能力存在的三种关系:热情优先、晕轮效应和补偿效应。最后,从判断者、被判断者等方面出发,回顾了影响热情和能力关系的主要因素。在此基础上,从研究内容、研究方法、毕生发展、文化差异等方面提出了未来研究的方向。     

基于PASS模型的汉语阅读障碍认知加工特点的实验研究

研究以智力的PASS认知模型为基础,考察了3-5年级阅读障碍组和正常对照组的PASS认知加工特点,探究汉语阅读障碍儿童的PASS认知缺陷模式,为后期的干预提供理论上的支持和帮助。结果发现,PASS四个认知加工均存在明显的年级差异,低年级儿童的PASS认知加工能力明显不如中高年级儿童。汉语阅读障碍儿童在DN: CAS 12项分任务上的成绩均低于正常对照组儿童。同时,大多数汉语阅读障碍儿童存在不止一种的PASS认知加工缺陷,即汉语发展性阅读障碍内部是一个异质群体;阅读障碍儿童在继时性加工上存在的问题最为严重,存在缺陷的人数也最多。     

中学生的思维风格与人格特质的关系

以497名中学生为被试,采用四种不同的统计方法,从多角度考察中学生的思维风格与人格特质之间的关系,为进一步探讨思维风格是否为介于智力和人格之间的一个中间变量奠定基础。结果发现,中学生的思维风格与人格特质之间存在稳定的对应关系,思维风格对人格特质的影响作用大于人格特质对思维风格的作用。     

Egocentric reciprocity and the role of friendship and anger

In this research, we examine the phenomenon of egocentric reciprocity, where individuals protect self-interest by adopting an eye-for-an-eye strategy in negatively imbalanced exchanges, and by taking advantage of overly generous treatment in positively imbalanced exchanges. We conducted two experiments using a modified ultimatum game examining attitudinal and behavioral responses to imbalanced exchanges. The experiments allowed us to explore the moderating role of relational closeness (i.e., whether the game partner was a friend or a stranger) and the mediating role of anger and indebtedness in these moderated relationships. Our results consistently demonstrate the phenomenon of egocentric reciprocity. Most importantly, this research reveals that friendship places a boundary on this egocentric tendency, and that the effects may partially be explained by anger experienced in response to exchange.
