宗教地理学是人文地理学的分支学科,研究宗教起源分布规律及其与地理环境的关系。其研究内容有宗教对政治经济、人口分布、聚落形式等方面的影响。本文利用在广东省档案馆等处所收藏的档案及文献资料、实地考察,研究浸信会开发广州东山口地区的过程,包括:一、教堂的建设与传教:基督教东山堂;二、教育机构的开设:培正小学、培正中学;三、出版机构的设立:美华书局;四、慈善机构的开办:恤孤院;五、东山口城区的开发与形成:高尚住宅区。     

Social Contact,Academic Satisfaction,COVID-19 Knowledge,and Subjective Well-being Among Students at Turkish Universities: a Nine-University Sample

Adverse effects of COVID-19 are seen not only on the physical health of infected individuals but also on their subjective well-being. Sudden changes in social lives, lockdowns, and shifts towards online education have had a negative impact on many people, especially university students. As part of an international study, the current study focused on the well-being of students at Turkish universities in relation to social contact, academic satisfaction, and COVID-19 knowledge. A total of 7363 students from nine universities (86.6% from state universities, 71.04% female, and 73.52% at bachelor’s level) participated in an online survey. Results revealed that females had lower levels of subjective well-being and academic satisfaction. According to a mediation model in the study, the relationship between social contact and well-being was mediated by academic satisfaction and COVID-19 knowledge. Our findings can guide future researchers, mental health professionals, universities, and policymakers to understand and improve subjective well-being of university students.

     

反映还是形成？平行还是层级？PSM的模型建构与检验

在心理学领域,传统的多指标潜变量的测量模型大都采用反映性建构,各指标反映了潜在构念,构念是各指标的原因.但实际上有些构念应该采用形成性建构,各指标是原因,形成了潜在构念.建构方式的选择不仅要从理论来考虑,还要通过数据特征来决定.研究以公共服务动机（PSM）构念为例,通过公益投资游戏取得投资绩效和满意度效标,验证了先前研究提出的“一阶反映二阶形成”建构模式,并进一步检验了层级性建构方式的优势,有助于PSM理论框架与实证测量的统一.     

工业与组织心理学中的前瞻性人格

前瞻性人格是指个体不受情境阻力的制约,主动采取行动以改变其外部环境的倾向性。相关的实证研究发现前瞻性人格对个体工作结果、职业生涯结果、团队效能、领导效能、新进人员适应性以及创业等后果变量均具有一定的影响。该文对工业与组织心理学领域有关前瞻性人格的相关研究进行了较为全面的总结,并在此基础上指出未来的研究有必要加强组织层面因素在前瞻性人格与相关结果变量之间的调节作用等三方面问题的探讨     

中小学生对教师的信任及问卷编制

通过查阅文献、开放式问卷调查、访谈、内容分析等方法提出了中小学生对特定教师的信任结构并编制问卷项目。以小学四年级至初中二年级学生为研究对象,对539名学生进行初步问卷调查,经探索性因素分析得到含20个项目的中小学生对教师信任问卷,然后对1012名学生进行正式调查和验证性因素分析。结果表明:中小学生对特定教师的信任是一个多维结构,包括学生对教师的教学能力、守信可靠和友善关怀三方面的判断;自编的问卷有良好的信度和效度,可作为进一步研究的工具。     

Nostalgia and Temporal Life Satisfaction

Recent research has shown that nostalgia, an apparently past-oriented emotion, may render the present self more positive and promote a brighter outlook on the future. The current study examined whether experimentally induced nostalgia would impact the levels of and associations among past, present, and future life satisfaction. Among 250 university students (86 males and 164 females, aged 16–26 years), nostalgia was manipulated through the recollection of nostalgic (vs. ordinary) events. In support of our hypotheses, the results showed that nostalgic experiences not only led to a larger contrast between past life satisfaction versus present and future life satisfaction, but also weaker associations between past and future life satisfaction and between present and future life satisfaction. Overall, the findings suggest that nostalgic experiences can render more distinct judgements on temporal life satisfaction.     

Serotonin transporter 5-HTTLPR genotype is associated with intrusion and avoidance symptoms of DSM-5 posttraumatic stress disorder (PTSD) in Chinese earthquake survivors

Background and Objectives: Prior studies have found that the serotonin transporter gene-linked polymorphic region (5-HTTLPR) interacts with trauma exposure to increase general risk for Posttraumatic Stress Disorder (PTSD). However, there is little knowledge about the effects of the interaction on distinct symptom clusters of PTSD. This study aimed to investigate the relation between the interaction of 5-HTTLPR and earthquake-related exposures and a contemporary phenotypic model of DSM-5 PTSD symptoms in a traumatised adult sample from China.

Design: A cross-sectional design with gene-environment interaction (G?×?E) approach was adopted. Methods: Participants were 1131 survivors who experienced 2008 Wenchuan earthquake. PTSD symptoms were assessed with the PTSD Checklist for DSM-5 (PCL-5). The 5-HTTLPR polymorphism was genotyped with capillary electrophoresis (CE) in ABI 3730xl genetic Analyzer.

Results: Although there was no significant interaction between 5-HTTLPR and traumatic exposure on total PTSD symptoms, respondents with the LL genotype of 5-HTTLPR who were highly exposed to the earthquake experienced lower intrusion and avoidance symptoms than those with the S-allele carriers.

Conclusions: The findings suggest that the 5-HTTLPR may have an important impact on the development of PTSD and add to the extant knowledge on understanding and treating of posttraumatic psychopathology.     

Mechanical behaviour of an Al–matrix composite reinforced with nanocrystalline Al-coated B4C particulates

In metal–matrix composites (MMCs), interfacial bonding between the metal matrix and the ceramic reinforcement plays a crucial role in their mechanical performance. In the present study, B₄C particles were cryomilled with an Al alloy to produce a composite powder, in which the B₄C was uniformly distributed in nanocrystalline Al. The cryomilling developed a strong bond between the B₄C and the Al, allowing the nanocrystalline Al to act as a coating with a strong ceramic–metal interface. This cryomilled composite powder was then introduced, as a reinforcement, into a conventional Al alloy to strengthen the material. After consolidation, the result was a bulk Al–matrix composite reinforced with B₄C particles encapsulated in nanocrystalline Al. This composite exhibits greatly improved strength and stiffness.     

Sources of motivation, interpersonal conflict management styles, and leadership effectiveness: a structural model

126 leaders and 624 employees were sampled to test the relationship between sources of motivation and conflict management styles of leaders and how these variables influence effectiveness of leadership. Five sources of motivation measured by the Motivation Sources Inventory were tested-intrinsic process, instrumental, self-concept external, self-concept internal, and goal internalization. These sources of work motivation were associated with Rahim's modes of interpersonal conflict management-dominating, avoiding, obliging, complying, and integrating-and to perceived leadership effectiveness. A structural equation model tested leaders' conflict management styles and leadership effectiveness based upon different sources of work motivation. The model explained variance for obliging (65%), dominating (79%), avoiding (76%), and compromising (68%), but explained little variance for integrating (7%). The model explained only 28% of the variance in leader effectiveness.
