中学欺侮行为现状研究 总被引:10,自引:0,他引:10
对湖南两所中学的399名中学生学校欺侮行为进行了研究,结果发现,经常受欺侮者为27%,欺侮者为14%。欺侮行为发生的地点是学校,发生的时间一般是课间。对于受欺侮者而言,没有性别差异,但是欺侮者以男生为主。受欺侮行为随年龄的增长在下降,而欺侮行为为则在上升。 相似文献

大学生人际信任变迁的横断历史研究 总被引:1,自引:0,他引:1
在当代剧烈的社会变迁背景下, 人们的信任水平可能会发生改变。本文采用横断历史研究方法, 对采用Rotter “人际信任量表”调查大学生人际信任水平的53篇研究报告进行了元分析, 这些文献涉及24233名大学生, 调查的时间跨度为1998年至2009年。研究结果表明:(1)我国大学生人际信任水平在这11年间显著降低, 相比1998年, 2009年时大学生的人际信任水平下降了1.19个标准差; (2)无论男生还是女生, 人际信任水平在11年间均显著下降, 其变化趋势和人际信任水平本身均不存在性别差异; (3)农村生源大学生的人际信任下降趋势呈边缘显著, 而城市生源大学生的人际信任水平没有明显变化, 但人际信任得分本身不存在生源地差异。 相似文献

The bundling literature largely holds that a person's reaction to a given product bundle depends only on the characteristics of the products contained in the bundle. This paper, instead, proposes that people evaluate bundles in reference to other bundles that they have seen. Prior research indicates that people are sensitive to a bundle's “attribute inventory” or the aggregate level of comparable attributes possessed by its constituent products. We show that when people evaluate a bundle, they compare the attribute inventories that it offers to those offered by other bundles that they have seen. The resulting compositional comparisons can occur without changes to the products that comprise the target and contextual bundles, vary by attribute comparability and attentional focus, and coexist with (and at times reverse the effects of) well‐established product‐specific context effects, which are determined solely by the products and their attributes. 相似文献

Conduct disorder (CD) symptoms and callous-unemotional (CU) traits have been shown to be uniquely associated with risky sexual behavior (RSB) in adolescence and early adulthood, yet their interactive role in predicting RSB remains largely unknown. This study aimed to investigate the predictive value of CD symptoms and CU traits, as well as their interaction, on several RSB outcomes in adolescence and early adulthood. A total of 683 participants (41.7 % female, 47.4 % African American) were followed annually and self-reported age of first sexual intercourse, frequency of condom use, pregnancy, contraction of sexually transmitted infections, and engagement in sexual solicitation from grade 7 to 2-years post-high school. CD symptoms predicted age of first sexual intercourse, condom use, and sexual solicitation. CU traits predicted age of first sexual intercourse and pregnancy. Their interaction predicted a composite score of these RSBs such that CD symptoms positively predicted the composite score among those with high levels of CU traits but not among those with low levels of CU traits. The current findings provide information regarding the importance of both CD symptoms and CU traits in understanding adolescent and early adulthood RSB, as well as the benefits of examining multiple RSB outcomes during this developmental period. These findings have implications for the development and implementation of preventive efforts to target these risky behaviors among adolescents and young adults. 相似文献

The aim of the present study is to reveal the most critical underlying factor influencing the mechanical properties of metal matrix composites (MMCs). It is shown that the mechanical properties of MMCs are essentially governed by the degree of strain localisation during plastic deformation. In other words, the MMCs exhibit superior mechanical performance only if the strain localisation is obviously inhibited and the accumulated stresses can be effectively transferred out. The work provides a new perspective in guiding the design of next-generation high-performance MMCs by suppressing the strain localisation as far as possible. 相似文献
