We review factors associated with school bullying and peer victimization in the People’s Republic of China (hereafter referred to as China) within the context of Bronfenbrenner (Am Psychol 32:513–531, 1977) ecological systems framework. Bullying and peer victimization are serious problems in Chinese schools, which calls for effective school-based bullying prevention and intervention strategies. However, understanding of this phenomenon has been limited because the majority of the empirical studies have examined individual characteristics (e.g., age, gender), and relatively few Chinese researchers have considered various contexts of the social ecology, such as cultural contexts. We first discuss the definition and prevalence, which is followed by a review of socio-demographic and ecological factors (micro-, meso-, exo-, and macrosystem) that are correlated with school bullying and peer victimization in Chinese schools. Findings from our review suggest that factors at the socio-demographic (age, gender, behavioral/mental health problems), micro- (parents, peers, and teachers), meso- (parents’ involvement in children’s school), exo- (mass media), and macrosystem (emphasis on academic achievement and collectivism vs. individualism) levels can foster or mitigate bullying and peer victimization among children and adolescents in Chinese schools. We then draw implications for assessment, practice, and policy concerning school bullying and peer victimization in China.  相似文献

采用时间比较法,考察数目及其呈现方式对时间知觉的影响。任务中,首先呈现标准时距,此时变化刺激的数目或呈现方式,然后呈现比较时距,被试的任务是判断比较时距比标准时距长还是短。实验1和实验2分别采用1秒内和1秒以上的时间,结果发现: 1秒内的时间加工中,刺激一个一个连续呈现时,小数引起标准时距的低估,大数导致标准时距的高估,而同时呈现时,刺激的数目对知觉到的时间无影响;数目及其呈现方式影响计时的准确性,而对计时的变异性和敏感性无影响。时间在1秒以上,同时呈现和连续呈现条件下,刺激的数目影响知觉到的时间;计时的  相似文献

This thesis reviews the development of family therapy in Taiwan since its commence in 1969 to today, with two focuses on the status quo in practice and in training. The practice of family therapy in local hospitals, social welfare agencies and community counseling institutes are reviewed respectively, with a discussion of the challenges local family therapists encounter. The status quo of local family therapy trainings is also examined in terms of trainers, programs, professional organizations and licensure. The limitations and possible hindrances to the current professional training system are explored, and finally suggestions for the advance of local family therapy professional development in Taiwan are proposed.  相似文献

探讨脑钠肽、内皮素测定在慢性阻塞性肺疾病(COPD)患者肺动脉高压、病情严重程度及近期预后评估的意义.观察60例COPD急性加重期患者,60例经治疗转为稳定期的患者,以30例健康者作对照.COPD急性加重期患者根据肺动脉压力分为肺动脉高压组(A组)30例、肺动脉压力正常组(B组)30例,根据病情分为轻度组21例、中度组23例、重度组16例.用免疫分析法测定血浆脑钠肽、内皮素浓度.结果COPD急性加重期组脑钠肽、内皮素浓度明显升高,稳定期组明显下降(P<0.001),但仍高于健康对照组(P<0.001);A组明显高于B组(P<0.05);重度组高于中度组(P<0.05),中度组高于轻度组(P<0.05).说明脑钠肽、内皮素浓度可反映COPD患者肺动脉压力情况及病情严重程度,有利于其疗效及近期预后评估.  相似文献

采用Gevers等的实验范式,以判断数字大小并选择不同言语符号方向信息左右为任务。材料为阿拉伯数字(1、2、8、9)和汉字、英文单词符号(“左”、“右”、“left”、“m#t”)。考察在不同语言符号方向信息下数字-空间联结SANBC效应的编码方式,结果发现:(1)在汉字和英文符号信息下,被试在数字大小比较任务中都表现出SNARC效应;(2)在汉字符号方向信息下。SNARC效应的编码方式主要存在视觉空间和言语空间编码,且以言语空间编码为主;(3)在英文符号方向信息下。SNARC效应的鳊码方式主要是视觉空间编码。  相似文献

Previous studies have shown that Asian American or Chinese individuals value low-arousal positive affect and a harmonious state of happiness more than European Americans do. However, the affective component of subjective well-being has mostly been defined as the presence of positive affect and the absence of negative affect. This definition emphasizes the importance of hedonic pleasure but fails to include the affect valued in Chinese culture. The present study developed the construct of peace of mind to describe the affective well-being valued in Chinese culture. Peace of mind was defined as an internal state of peacefulness and harmony. To develop a measure to assess peace of mind, three studies were conducted. Study 1 developed the Peace of Mind Scale (PoM), Study 2 established its validity as an affective well-being measure, and Study 3 found that individuals from Chinese cultures score higher on this scale than those from Western cultures. The results indicate that the PoM has good reliability and validity for measuring affective well-being. The cross-cultural validation also found that Taiwanese individuals scored higher on the PoM than European Americans, which provides further evidence of good construct validity of the PoM.  相似文献

基于权力的情境聚焦理论, 研究从权力认知的视角探讨了在中国背景下, 政府组织中员工个人权力感知与他/她对上级的进谏行为的关系及其作用机制和边界条件。通过对苏南等地区政府组织的306名机关工作人员及其直接上级配对成组取样, 采用层级回归等数据分析方法。研究结果发现, 员工的个人权力感知与其进谏行为之间成正相关, 并且这种关系是以认知灵活性和心理可得性为中介起作用的。个人权力感知与中介变量之间的关系又受到员工的权力距离倾向的正向调节影响, 即权力距离倾向越大, 这种正向关系越强。文章还讨论了所得结果的意义及未来研究。  相似文献

Previous research has shown that when the targets of successive visual searches have features in common, response times are shorter. However, the nature of the representation underlying this priming and how priming is affected by the task remain uncertain. In four experiments, subjects searched for an odd-sized target and reported its orientation. The color of the items was irrelevant to the task. When target size was repeated from the previous trial, repetition of target color speeded the response. However, when target size was different from that in the previous trial, repetition of target color slowed responses, rather than speeding them. Our results suggest that these priming phenomena reflect the same automatic mechanism as the priming of pop-out reported by Maljkovic and Nakayama (1994). However, the crossover interaction between repetition of one feature and another rules out Maljkovic and Nakayama's (1994) theory of independent potentiation of distinct feature representations. Instead, we suggest that the priming pattern results from contact with an episodic memory representation of the previous trial.  相似文献

CPEB-1 is a sequence-specific RNA binding protein that stimulates the polyadenylation-induced translation of mRNAs containing the cytoplasmic polyadenylation element (CPE). Although CPEB-1 was identified originally in Xenopus oocytes, it has also been found at postsynaptic sites of hippocampal neurons where, in response to N-methyl-D-aspartate receptor activation, it is thought to induce the polyadenylation and translation of alphaCaMKII and perhaps other CPE-containing mRNAs. Because some forms of synaptic modification appear to be influenced by local (synaptic) protein synthesis, we examined long-term potentiation (LTP) in CPEB-1 knockout mice. Although the basal synaptic transmission of Schaffer collateral-CA1 neurons was not affected in the knockout mice, we found that there was a modest deficit in LTP evoked by a single train of 100 Hz stimulation, but a greater deficit in LTP evoked by one train of theta-burst stimulation. In contrast, LTP evoked by either four trains of 100 Hz stimulation or five trains of theta-burst stimulation were not or were only modestly affected, respectively. The deficit in LTP evoked by single stimulation in knockout mice appeared several minutes after tetanic stimulation. Long-term depression (LTD) evoked by 1 Hz stimulation was moderately facilitated; however, a stronger and more enduring form of LTD induced by paired-pulse 1 Hz stimulation was unaffected. These data suggest that CPEB-1 contributes in the translational control of mRNAs that is critical only for some selected forms of LTP and LTD.  相似文献
