Active school travel is associated with fewer suicide attempts among adolescents from low-and middle-income countries

Background/Objective: This study explored the association between active school travel (AST) and suicide attempts among adolescents in low- and middle-income countries (LMICs). Method: We used the data from the Global School-based Health Survey, including 127,097 adolescents aged 13-17 years from 34 LMICs. A self-reported survey was used to collect data on AST and suicide attempts as well as some variables. Multivariable logistic regression was performed to assess the association between AST and suicide attempts. A meta-analysis with random effects was undertaken to identify the difference in the association between AST and suicide attempts. Results: Across all the adolescents, the prevalence of AST was 37% and the prevalence of suicide attempts was 11.60%. Adolescents who engaged in AST were less likely to have suicide attempts irrespective of gender. The country-wise analysis indicated a large inconsistency in the association between AST and suicide attempt across the countries. Conclusions: AST would appear to be a protective factor for reducing suicide attempts among adolescents. However, the association between AST and suicide attempts varied greatly across the countries. Future studies should confirm the association between AST and suicide attempts.     

日本侵略战争中的宗教动员

一、日本神道教的宗教动员在历次侵略战争中,日本军国主义政府以神道教为国教,发动佛教及其他宗教实施宗教动员。1.神道教的宗教动员思想神道教主张“神国日本”在世界上的绝对优越性,具有领导全世界的责任和神圣使命感。天皇是创造日本国的天照大神的直系子孙,具有神权,是日本唯一正统的统治者,国民必须对天皇绝对崇敬和绝对服从。而且臣民必须“忠于天皇”、“敬神崇祖”、“灭私奉公”,甚至要求“一旦如有缓急,当义勇奉公,以扶翼天壤无穷之皇运”,即要求一旦遇有战争等非常事态,要为天皇制国家卖命。而以天皇名义发动的战争则是“圣战”,…     

科学之魂——谈科学家崇尚科学精神

由于职业的关系,作为一位科普期刊记者的我常和科学家们打交道。走进这支特殊群体的内心世界,他们向我吐露心扉,为我讲述他们毕生执著追求的科技事业。我这才得知他们的故事很精彩。我常常把他们美誉为“金字塔上的人物”,这是因为这些科学家们用他们的卓而不群的智慧,将呕心沥血的科研成果广泛应用于实际生产当中,推动了中国乃至世界的生产力的发展。他们是最可爱的人。我常常思索这么一个问题:是什么样的一种力量支撑着这些科学家们投入到物我两忘、宠辱不惊的伟大的科技事业?继而,为了全人类生产力的发展,为全人类谋求一个和谐、幸福、和…     

Conversation Orientation Moderates the Relationship between Information Sharing of Medically Assisted Reproduction and Child Adjustment

Parents who experienced infertility have increasingly used medically assisted reproduction (MAR) to add children to their families over the past few decades. These parents will need to decide if they will tell their children about being conceived using MAR. Although MAR information sharing operates within family contexts, little is known about the role of conversation orientation—one family contextual factor—in child outcomes associated with MAR information sharing in middle childhood. Derived from the Family Communication Patterns Theory, this study proposes that conversation orientation moderates the associations between MAR information sharing and children's psychosocial adjustment. This proposal was tested using a sample of 81 6- to 12-year-old MAR-conceived children from 55 families and a structured observational measure of conversation orientation. Multiple regression analyses showed that MAR information sharing interacted with conversation orientation to influence children's behavioral and attention problems but not emotional problems. In families with high conversation orientation, MAR information sharing was not significantly associated with children's behavioral and attention problems. In families with low conversation orientation, MAR information sharing was significantly associated with an increase in children's behavioral and attention problems. Results of this exploratory study demonstrate the potential significance of general communication orientation in understanding child outcomes of MAR information sharing and highlight the needed family context nuances in MAR research.

Relative deprivation: A mechanism for the ostracism–aggression link

In five studies, we tested whether ostracism triggers feelings of relative deprivation and whether relative deprivation accounts for the impact of ostracism on aggression. Relative to participants who recalled either inclusive or neutral experiences, participants who recalled ostracism experiences reported higher levels of relative deprivation (Study 1). Furthermore, the feeling of relative deprivation mediated the effect of ostracism on aggression (Studies 2, 3a, and 3b). Framing ostracism as an experience of nondeprivation weakened the connection between ostracism and aggression (Study 4), which suggests an effective way of reducing aggression following an ostracism experience. Together, these findings highlight the significance of relative deprivation in shaping people's responses toward ostracism.

能力还是热情?广告诉求对消费者品牌认同和购买意向的影响

基于自我建构理论和情绪理论, 本文探讨了自我建构与广告诉求对品牌认同的交互作用、影响机制及边界条件。通过3个实验, 我们发现对于独立自我建构的消费者来说, 能力广告诉求更能提高品牌认同感, 而对于相依自我建构的消费者来说, 热情广告诉求则更有效; 同时我们也验证了广告诉求到愉悦感到品牌认同最终到购买意向的因果链模型, 并确定了企业类型对该机制的调节作用。     

外观新颖性对消费者购买意愿的影响：自我建构与产品类型的调节效应

外观创新在市场竞争中的地位越来越突出,然而因此而导致的成败案例都很普遍。如何进行外观创新更受消费者欢迎,其内在机制是什么,我们却知之甚少。基于独特性需求理论、风险感知理论及自我建构理论,本文探讨了自我建构与外观新颖性对消费者购买意愿的交互作用、影响机制以及边界条件。通过3个实验,发现对于独立型自我建构的消费者而言,高外观新颖性能引发独特性需求从而提高购买意愿,而对于相依型自我建构而言,低外观新颖性则通过降低社会风险感知从而提高购买意愿;同时,本文也确定了产品类型对该机制的调节作用,具体来讲,对于实用品,所有消费者都对低外观新颖性产品具有更强的购买意愿,而对于享乐品,所有消费者都对高外观新颖性产品具有更强的购买意愿。
