Early psychological consequences of the March 11, 2004, terrorist attacks in Madrid, Spain

On March 11, 2004, Al-Qaeda set off 10 bombs on several train routes in Madrid. 192 people were killed and 2,000 wounded. In this study, 1,179 questionnaires were administered Week 2 after the attacks to residents 18 years and over from the affected geographical areas. The questionnaire included items about sociodemographic variables and exposure to the attacks. Psychological effects were assessed as presence of acute stress and depressive symptomatology and functional impairment. 46.7% of the sample presented symptomatology of acute stress and 49.6% depressive symptoms. Among the symptoms of acute stress, the most frequent were re-experiencing (72.5%) and dissociative symptoms (71.8%). The chief predicting variables in symptomatology were being female, over 65 yr. old, and a habitual train user. The large number of affected people was refined with an item analysis and the consideration of severity of interference in psychosocial functioning.     

Female physical attractiveness in Britain and Malaysia: a cross-cultural study

Two purported cues to perceived female physical attractiveness are body mass index (BMI) and body shape as measured by the waist-to-hip ratio (WHR). This study examined the relative contribution of both cues in several culturally socio-economically distinct populations. Six hundred and eighty-two participants from Britain and Malaysia were asked to rate a set of images of real women with known BMI and WHR. The results showed that BMI is the primary determinant of female physical attractiveness, whereas WHR failed to emerge as a significant predictor. The results also showed that there were significant differences in preferences for physical attractiveness along a gradient of socio-economic development, with urban participants preferring images of women with significantly lower BMIs than their rural counterparts. The findings are discussed in terms of evolutionary psychological explanations of mate selection, and sociocultural theory, which emphasises the learning of preferences for body sizes in social and cultural contexts.     

班级环境与青少年抑郁的关系：核心自我评价的中介与调节作用

通过整群抽样的方法抽取了1404名中学生,对其施测核心自我评价量表,我的班级问卷和抑郁问卷,应用无约束结构方程模型技术和结构方程中介效应检验技术,分别考察了核心自我评价在班级环境与抑郁关系间的调节与中介作用。结果表明：（1）核心自我评价对班级环境中的师生关系、同学关系、竞争三者和抑郁之间的关系起着调节作用,但结构模型的拟合指数不佳;（2）核心自我评价在班级环境与青少年抑郁间起着中介作用,其中核心自我评价在竞争与抑郁间关系起着完全中介作用。     

互依性与团队协作

互依性是指团队成员在完成作业的过程中相互依赖的程度,分为作业互依性和产出互依性两大类。该文全面的阐述了互依性的概念、分类和测量方法,并重点介绍了20世纪90年代以后有关互依性在团队协作领域中的研究结果。总结发现,两类互依性与很多团队变量均有显著相关,特别是团队的结果变量。在对结果变量的影响上,两类互依性存在交互作用,或互依性与其他变量存在交互作用。文章最后提出了目前研究的局限性,以及未来的研究展望
