日常小团体多样性与老年人身体症状的关系：团体积极情绪的中介作用和心理压力感的调节作用

采用日记追踪法,以53名老年人为被试,探讨日常小团体的多样性对其身体症状的影响及机制。结果显示:(1)日常小团体内多样性负向预测老年人当天的身体症状;(2)在个体内水平,团体积极情绪在老年人小团体内多样性对身体症状的关系中起中介作用;(3)心理压力感能够跨层正向调节日常小团体内多样性对每日身体症状的影响。研究结果有助于揭示小团体多样性如何与老年人身体症状相联系,以及两者之间的关系在何种条件下更强,这对于老年人身体症状的干预工作具有一定实践意义。     

Nothing But Stereotypes? Negligible Sex Differences Across Creativity Measures in Science,Arts, and Sports Adolescent High Achievers

Previous research has focused on understanding when, why, and how sex differences in creativity occur, as results vary across samples, measures, and methodologies. In the current study we investigated sex differences in creativity among 984 high achieving adolescents in three expertise areas: Sciences, Arts, and Sports. Eight creativity indicators were analyzed: Alternative uses task (AUT) fluency; creative self-efficacy (CSE); intraindividual strengths (difference between CSE and AUT Fluency); five self-reported creativity scales: Self/everyday, scholarly, performance, mechanical/scientific, artistic. The results showed negligible sex differences ( $n_{\mathrm{p}}^2$ = .01), with females performing better in AUT Fluency and males self-rating their CSE higher. No sex differences were found in self/everyday, scholarly and performance creativity. Males self-rated their mechanical/scientific creativity ( $n_{\mathrm{p}}^2$ = .06) higher than females; while females self-rated their artistic creativity ( $n_{\mathrm{p}}^2$ = .02) higher in comparison to males. Our results extend the existing literature by finding negligible sex differences in adolescent expert groups. However, some stereotypical differences emerged, for example, females with Sciences expertise rated their mechanical/scientific creativity lower than males with and even without Sciences expertise. Results call for further investigation into the links between sex differences, expertise, and specific creativity domains.     

农药白草枯急性中毒的研究进展

本文对近期百草枯急性中毒研究进展进行了综述,从临床角度对百草枯急性中毒的研究进行哲学思考,指出应从以下几个方面开展研究：研究发现有效拮抗剂;进行综合系统的实验研究;建立全国性救治中心;重视救治成功的个案报道;组织多中心、大样本的临床研究;多学科协作。     

急性心肌梗死复杂冠脉病变延迟支架植入治疗策略

目前我国临床实践中,急性心肌梗死的急诊介入治疗几乎均以一次性植入支架为手术终点。然而急性心肌梗死患者常伴有复杂冠脉病变,此类患者一次性植入支架常出现“慢血流”或“无复流”现象,导致心肌微循环灌注障碍,直接影响患者的预后。本文从临床策略的角度出发,探讨此类患者急诊冠脉介入治疗中延迟植入支架治疗的策略及可行性。     

食管癌术后急性肾衰竭的临床分析

为了探讨食管癌术后急性肾衰竭发生的原因及防治经验,回顾性分析13例术后发生急性肾衰竭食管癌患者的临床资料,并总结防治体会。结果显示患者平均年龄67.5岁,体重50.4千克,皆有严重的吞咽梗阻症状,其中8例术前发现低蛋白血症,3例术前有不同程度的肾功能不全;术后3天内出现急性肾衰竭,治疗纠正肾前性病因、利尿和改善肾血流灌...     

不同人群对留守儿童问题行为的认知差异研究

通过问卷调查探索不同人群对留守儿童问题行为的认知差异。对五个年级的265名学生及其班级任课教师、监护人及社会一般人群进行问卷团体施测。结果显示:不同人群对留守儿童问题行为认知差异极其显著,其中教师与家长评价最低,一般人群评价次之,学生自评最好;不同群体均认为留守儿童男性问题行为严重于女性;对留守男性儿童,教师评价最低,对留守女性儿童,儿童自评最好;年级主效应极其显著,即随年级增高,问题行为评价越严重。     

Output order reflects the cognitive accessibility of goals

Goal accessibility--the ease or speed with which a goal is activated--increases the likelihood that it will be acted on. The present studies validate output order as a measure of goal accessibility that can be applied to goal lists in both laboratory and naturalistic settings. In three studies, output order (the order in which goals are listed in a free-response format) was related to self-reported goal value but was not redundant with it. Furthermore, output order was affected by motivational priming whereas value was not, and order associated with typical student goals (e.g., achievement) compared with atypical goals (e.g., power). Output order is well suited to bring the study of accessibility to naturalistic studies of goals and goal pursuit.     

认知诊断测验中基于信息矩阵的多群组DIF检验

基于改进的Wald统计量,将适用于两群组的DIF检测方法拓展至多群组的项目功能差异（DIF）检验;改进的Wald统计量将分别通过计算观察信息矩阵（Obs）和经验交叉相乘信息矩阵（XPD）而得到。模拟研究探讨了此二者与传统计算方法在多个群组下的DIF检验情况,结果表明：（1）Obs和XPD的一类错误率明显低于传统方法,DINA模型估计下Obs和XPD的一类错误率接近理论水平;（2）样本量和DIF量较大时,Obs和XPD具有与传统Wald统计量大体相同的统计检验力。     

社会群体的实体性:回顾与展望

社会群体的实体性是指群体被知觉为一个真正独立存在的有意义实体的程度.它受到知觉者、社会情境和文化等因素的影响.实体性在群际关系中具有重要意义,它影响着认同、刻板印象,偏见和群际冲突.实体性从本质上来说并不是绝对积极的或消极的群体特征,它主要取决于知觉者与群体的关系性质和其所处的情境.对中国研究者而言,如何让实体性最大可能地发挥积极作用,以利于群体关系的和谐是未来研究应该努力的方向;加强中国文化背景下实体性与群际关系的研究,为解决中国各社会阶层以及不同群体之间的和谐相处提供理论上的指导也是未来可以关注的方向.
