Cross-cultural studies of dementia: use of a Chinese version of the Blessed-Roth Information-Memory-Concentration test in a Shanghai dementia survey

A culturally adapted Chinese version of the Blessed-Roth Information-Memory-Concentration test (CIMC) was used in a dementia screening survey of a probability sample of 5,055 elderly Shanghai residents. The individual items on the CIMC that best predicted the overall score were similar to the best predictor of an American version of the IMC. Performance on the CIMC was markedly affected by the level of education or lack thereof. In a subsample for whom clinical diagnoses were obtained, it was possible to establish cutoff values on the CIMC by stratifying the sample according to education.     

Does a Booster Intervention Augment the Preventive Effects of an Abbreviated Version of the Coping Power Program for Aggressive Children?

Booster interventions have been presumed to be important methods for maintaining the effects of evidence-based programs for children with behavioral problems, but there has been remarkably little empirical attention to this assumption. The present study examines the effect of a child-oriented booster preventive intervention with children who had previously received an abbreviated version (24 child sessions, 10 parent sessions) of the Coping Power targeted prevention program. Two hundred and forty-one children (152 boys, 89 girls) were screened as having moderate to high levels of aggressive behavior in 4th grade, then half were randomly assigned to receive the abbreviated Coping Power program in 5th grade, and half of the preventive intervention children were then randomly assigned to a Booster condition in 6th grade. The Booster sessions consisted of brief monthly individual contacts, and were primarily with the children. Five assessments across 4 years were collected from teachers, providing a three-year follow-up for all children who participated in the project. Results indicated that the abbreviated Coping Power program (one-third shorter than the full intervention) had long-term effects in reducing children’s externalizing problem behaviors, proactive and reactive aggression, impulsivity traits and callous-unemotional traits. The Booster intervention did not augment these prevention effects. These findings indicate that a briefer and more readily disseminated form of an evidence-based targeted preventive intervention was effective. The findings have potential implications for policy and guidelines about possible intervention length and booster interventions.     

Enhanced plastic deformation in a metallic glass induced by notches

It is shown that the compressive plasticity of a metallic glass, namely Zr_52.5Ni_14.6Al₁₀Cu_17.9Ti₅, can be improved by the introduction of two symmetrical notches. The enhanced plasticity may be ascribed to a blocking effect of the propagation of shear bands caused by large stress gradients around the notches. In contrast to ceramic specimens with similar notches, the plasticity enhancement of metallic glass induced by notches can provide a new approach to understanding its unique mechanism of deformation.     

Associations Among Body Mass Index,Depression, and Family Factors Across Two Generations

In this pilot study, we examined the relationship between health factors, sociodemographic factors, and body mass index (BMI) across two generations (n = 41 parent-child pairs). Generation 1 study variables included parent- and family-focused characteristics and health variables, the Generation 2 variables included child demographic factors, and the outcome variable was youths’ physical health (operationalized as BMI). Regression models revealed that Generation 1 variables, taken together, accounted for 26% of the variance in youth BMI. However, only the parent’s mental health symptoms (i.e., depression symptoms) made a unique contribution to the variance in youth BMI. Logistic regression analysis revealed that the youths’ race and age—but no other demographic factor—were significantly related to youth BMI-for-age. Our findings suggest that youth race, age, and parent mental health are each associated with youth physical health (i.e., BMI), confirming previous study findings that parental factors and demographic factors should be considered when exploring youth health outcomes.     

周代士婚礼对中国古代王室婚礼的影响

中国传统婚礼礼仪来源于儒家礼学经典著作《仪礼·士昏礼》中所反映的周代婚姻六礼,但这些礼仪是怎样影响中国古代的王室婚礼,时至今日没有任何学者对此作过全面系统的解释并得出令人信服的结论。文章运用比较研究的方法,从议婚到结婚过程中的文辞话语和仪式要素两个方面,全面深入地比较了周代士婚礼与秦汉以后部分朝代王室婚礼的共同性和差异性。就此认为,中国古代以汉族为主的历代王室婚礼的基本范式均来自于周代的士婚礼,以其他民族为主建立政权而形成的王室婚礼则具有各自的区域民族特色,从而使得中国古代的王室婚礼在总体上形成了一种具有二元结构的仪式象征符号体系。     

基于N2pc成分的视觉空间注意功能老化机制

视觉空间注意是人的一种基本认知功能,对老年人的生活有重要影响。N2pc作为一种与注意选择相关的ERP成分,可以反映注意资源在空间上的分配,是研究视觉空间注意的一个良好指标。本文对此前基于N2pc成分的注意功能老化研究进行了综述。前人研究主要采用视觉搜索范式与空间线索范式。采用视觉搜索范式的研究发现,当目标周围有干扰子时,目标诱发的N2pc在老年人中振幅减小,潜伏期延迟,同时在行为上老年人与年轻人相比,正确率更低,反应时更长; 当目标周围无干扰子时,目标诱发的N2pc振幅老年人与年轻人相当或比年轻人更大,老年人的正确率与年轻人无显著差异。采用空间线索范式的研究发现,与目标无相同特征的线索奇异子(singleton cue)不会诱发N2pc,与目标有相同特征的线索奇异子诱发的N2pc未表现出年龄差异,差异体现在一种反映抑制的ERP成分—Pd上(年轻人有Pd而老年人没有),此时老年人在行为上表现出比年轻人更强的空间线索效应。这些研究共同说明,视觉空间注意功能的老化是一个复杂的过程,涉及到搜索目标时注意分配速度的减慢,对干扰子抑制能力的下降以及基于特征的注意捕获能力的良好保持。     

Personality expression in Chinese language use

To date, little research has investigated personality expressions in languages other than English. Given that the Chinese language has the largest number of native speakers in the world, it is vitally important to examine the associations between personality and Chinese language use. In this research, we analysed Chinese microblogs and identified word categories and factorial structures associated with personality traits. We also compared our results with previous findings in English and showed that linguistic expression of personality has both universal‐ and language‐specific aspects. Expression of personality via content words is more likely to be consistent across languages than expression via function words. This makes an important step towards uncovering universal patterns of personality expression in language.     

Hume's Dispositional Account of the Self

This paper will argue that Hume's notion of the self in Book 2 of the Treatise seems subject to two constraints. First, it should be a succession of perceptions [THN 2.2.1.2, 2.1.2.3]. Second, it should be durable in virtue of the roles that it plays with regard to pride and humility, as well as to normativity. However, I argue that these two constraints are in tension, since our perceptions are too transient to play these roles. I argue that this notion of self should be characterized as a bundle of dispositions to our perceptions, such that these dispositions are durable and counterfactual-supporting. I argue that Hume confused his ‘philosophical’ notion of dispositions, as nothing above and beyond their effects, with the thicker notion of dispositions to which the passions respond—which explains his mistaken commitment to the durability constraint.     

Egocentric reciprocity and the role of friendship and anger

In this research, we examine the phenomenon of egocentric reciprocity, where individuals protect self-interest by adopting an eye-for-an-eye strategy in negatively imbalanced exchanges, and by taking advantage of overly generous treatment in positively imbalanced exchanges. We conducted two experiments using a modified ultimatum game examining attitudinal and behavioral responses to imbalanced exchanges. The experiments allowed us to explore the moderating role of relational closeness (i.e., whether the game partner was a friend or a stranger) and the mediating role of anger and indebtedness in these moderated relationships. Our results consistently demonstrate the phenomenon of egocentric reciprocity. Most importantly, this research reveals that friendship places a boundary on this egocentric tendency, and that the effects may partially be explained by anger experienced in response to exchange.
