The Balanced Pseudocomplemented Ockham Algebras with the Strong Endomorphism Kernel Property

Studia Logica - An endomorphism on an algebra $${\mathcal {A}}$$ is said to be strong if it is compatible with every congruence on $${\mathcal {A}}$$ ; and $${\mathcal {A}}$$ is said to have the...     

Violence Exposure and Sexual Risk Behaviors for African American Adolescent Girls: The Protective Role of Natural Mentorship and Organizational Religious Involvement

African American adolescent girls are at increased risk of being exposed to community violence and being diagnosed with a sexually transmitted infection. Fewer studies, however, have examined the protective roles of natural mentorship and organizational religious involvement as potential moderators that could lessen the effects of violence exposure on health risk behavior. Data from 273 African American ninth grade girls were used to test hypothesized independent and moderated‐moderation models. Results suggest that natural mentorship and religious involvement were protective for girls who reported at least one mentor and moderate to high levels of religious involvement. Our findings may be relevant for community stakeholders and organizations that directly interact with religious institutions and community programs that focus on outreach to African American adolescent girls.     

基于分部评分模型思路的多级评分认知诊断模型开发

基于分部评分模型的思路, 本文提出了一般化的分部评分认知诊断模型(General Partial Credit Diagnostic Model, GPCDM), 与国际上已有的基于分部评分模型思路的多级评分模型GDM (von Davier, 2008)和PC-DINA (de la Torre, 2012)相比, GPCDM的Q矩阵定义更加灵活, 项目参数的约束条件更少。Monte Carlo实验研究表明, GPCDM模型的参数估计精度指标RMSE介于[0.015, 0.043], 表明估计精度尚可; TIMSS (2007)实证数据应用研究表明, 与GDM和PC-DINA模型相比, GPCDM与该数据的拟合度更好, 并且使用GPCDM分析该数据的诊断效果也更优。总之, 本研究提供了一种约束条件更少、功能更为强大的多级评分认知诊断模型。     

Functional magnetic resonance imaging activation in response to prompts of romantically disillusioning events

To differentiate romantic disillusionment from similar constructs of dissatisfaction and regret, functional Magnetic Resonance Imaging (fMRI) data obtained when romantically involved individuals (N = 39) were reminded of relationship events representing these emotions were analyzed. Whole‐brain activations suggested disillusionment‐linked processes not observed for dissatisfaction or regret. Compared to dissatisfying events, disillusioning ones showed greater activity in regions pertaining to evaluation, reflection, and reconciling conflicting information (e.g., anterior cingulate cortex). No regions showed significantly more activation for dissatisfying than disillusioning events. Compared to regret‐inducing events, disillusioning events showed greater activation in areas thought pertinent to detail processing and decision making (occipital fusiform and lingual gyrus). Regret‐inducing events activated regions suggesting the planning and thoughts of how one could have acted differently (e.g., prefrontal cortex).     

不同社会群体特征对内隐领导因素的影响

研究发现,中国人内隐领导理论的内容由个人品德、目标有效性、人际能力和多面性四个因素构成。不同的年龄、职业和教育水平等评分者的特点,对领导诸因素的评分有着显著的影响。综合分析发现,教育水平是影响内隐领导因素评分的主要变量。另外,各组都倾向于把人际能力作为领导最大的特质来加以评分。     

社会称许性反应的测量与控制

社会称许性反应是影响人格测验效度最常见的一种反应偏差,从20世纪30年代至今,测量学家一直努力揭示社会称许性反应的性质和内部结构,并开发社会称许性量表对其直接测量。本文综述了社会称许性量表的发展脉络,指出了至今遗留的问题。并且,从事前控制和事后控制的角度,对当前主要的控制社会称许性反应的方法进行了论述,指出了社会称许性量表的效度对事后控制方法的重要影响,并给出了一些如何控制社会称许性反应的指导建议。

Physical interpersonal relationships and social anxiety among online game players.

Many online game players spend inordinate amounts of time in their favorite virtual worlds. A large percentage of these players are teenagers who show behaviors normally associated with physical addiction. Parents, educators, and social scientists are therefore saying that online games are sources of social problems. The authors surveyed 174 Taiwanese college-age online players to collect data on the potential effects of online games on the quality of interpersonal relationships and levels of social anxiety. According to the results, the quality of interpersonal relationships decreased and the amount of social anxiety increased as the amount of time spent playing online games increased.     

学前儿童对生物衰老的认知

按照“朴素理论”的要素设计研究任务,研究一探查学前儿童能否以衰老这一生命特征为标准做出生物和非生物的本体区分,以及能否对衰老做出生物性而非意图的因果解释;研究二进一步探查学前儿童对生物衰老特性（普遍性和不可逆性）的认知。结果显示,4、5、6岁学前儿童在分类作业中的认知成绩随年龄逐渐提高,而在因果解释中,各年龄组儿童都不用心理意图作为衰老的原因;他们对衰老的认知与其对生长的认知密不可分;学前儿童对衰老两个特性的认知不同步;由研究结果可以推论,6岁儿童在衰老维度上具有了较稳定的朴素生物理论。
