On the neurobiological redefinition of psychiatric symptoms: elimination,reduction, or what?

Synthese - Because biologization of psychiatric constructs does not involve derivation of laws, or reduce the number of entities involved, the traditional term of ‘reduction’ should be...     

Right- and left-wing prejudice toward dissimilar groups in cultural and economic domains

According to recent studies, people on both the political right and left show prejudice toward groups whose beliefs are in conflict with their own. This prediction applies to both cultural and economic dimensions of political beliefs. In three studies (N = 499) we demonstrate that people on both the cultural and economic right and left show negative attitudes toward groups on the other side of the given spectrum and that underlying this effect is the perception of value violation. In two out of three studies, we manipulated the extremity of target worldviews to further explore the causal chain between political beliefs, the perception of value violation, and prejudice. Our results showed a high degree of symmetry between the political left and right in their attitudes toward groups with dissimilar beliefs. However, although people on both sides of the political spectrum show prejudice toward each other, people on the cultural and economic right seem to be more sensitive to value violations than people on the left.

国有大中型企业员工心理应激研究

本研究以Andre Billrtte和Renand Bouchardr的五因素理论为基础,结合我国国有大中型企业的实际情况,提出国有大中型企业员工心理应激源的六维结构。以此为切人点．编制国有大中型企业员工心理应激问卷,施测于392名员工,通过因素分析,得出国有大中型企业员工心理应激源的六维结构：生产压力、同事关系、与直接主管的关系、纪律控制、工作单调和职业发展。再进行信度和效度的检验,形成国有大中型企业员工心理应激目标问卷。     

视觉感觉记忆信息在模式识别中的作用

该研究设计了新的实验方法进行了两项全部报告实验和两项抽样模式识别实验,考察视觉感觉记忆(visual sensorymemory,VSM)信息在模式识别中的作用。结果发现,在限定利用短时记忆(shor-term memory,STM)信息的抽样模式识别作业中,识别出的模式与转换到短时记忆的模式在数量上无显著性差别,而在短时记忆和感觉记忆信息都可能利用的识别作业中,虽然转换到短时记忆的模式数量并未增加,但识别出的模式比转换到短时记忆的模式数量增加了1倍(P<0.001)。这表明,未能转换到短时记忆的感觉记忆信息可被直接用于模式识别。     

关于城市居民心理凝聚感与压力源关系的研究

使用问卷测试方式对城市居民的心理凝聚感和压力源之问的关系进行研究。结果发现,在7种压力源因子和压力源总分中,经济收支和工作压力、家庭生活事件、知识技能更新3个压力源因子和压力源总分在三个级别的心理凝聚感组之间存在显著差异,心理凝聚感水平高的被试,对外界工作生活事件产生了最低的压力评价。职业、经济收入不同的群体在心理凝聚感的得分上存在显著的差异,经济收入高的个体有较高的心理凝聚感。说明不同心理凝聚感水平的被试面对相同的工作生活压力,其压力认知评价存在差异。     

Measuring up: Academic performance of Canadian immigrant children in reading,mathematics, and science

Using the Canadian sample from the Programme for International Student Assessment, this study examined the effects of student and school characteristics on academic achievement of immigrant and non-immigrant students. No differences were found in mathematics achievement, but non-immigrant students outperformed immigrant students in both reading and science achievement. At the student level, there was more gender equity in academic achievement among immigrant than non-immigrant students. Socioeconomic inequity was related to fathers among immigrant students but to both mothers and fathers among non-immigrant students. Home language had weaker effects among immigrant than non-immigrant students. At the school level, teacher-student ratio, teacher morale, and academic pressure were predictors for immigrant students, whereas disciplinary climate for non-immigrant students. Non-immigrant students demonstrated tremendous regional differences that were absent among immigrant students.     

我国城市居民消费心理预期的结构及其影响因素研究

本研究采用自编《消费心理预期结构问卷》对1097名城市居民进行了研究,结果表明：1《消费心理预期结构问卷》具有较高的信度和效度;2．消费心理预期由预测经历、信息量、价格知觉水平、信息来源与渠道,以及预测依据等5个因素构成;3．现阶段,我国城市居民消费心理预期的一般特点是预期的准确性不高预期的理性化程度尚有待提高;影响消费心理预期结构的主要因素是消费者的性另、年龄、学历、职业和所在城市等变量。     

Assessing potential effects of daily cross-domain usage of information and communication technologies

ABSTRACT

A within-person diary research design with 39 full-time workers was used to examine the effects of daily cross-domain usage of information and communication technologies (ICTs) on job-related performance and stress in both workplace and home domains. Segmentation preference effects on links between cross-domain ICT usage and both job performance and job stress were also analyzed. A positive association was found for the first relationship in mixed home-workplace contexts, and a negative association for the second in home contexts only. A stronger segmentation preference effect on the negative relationship between cross-domain ICT usage and job stress was found for integrators (employees who integrate work and home domains) compared to separators (employees who separate work/non-work activities). Our findings suggest that daily cross-domain ICT usage can enhance job performance and reduce job stress, with a moderating effect of segmentation preference on the link between cross-domain ICT usage and job stress.     

An empirical Q-matrix validation method for the sequential generalized DINA model

As a core component of most cognitive diagnosis models, the Q-matrix, or item and attribute association matrix, is typically developed by domain experts, and tends to be subjective. It is critical to validate the Q-matrix empirically because a misspecified Q-matrix could result in erroneous attribute estimation. Most existing Q-matrix validation procedures are developed for dichotomous responses. However, in this paper, we propose a method to empirically detect and correct the misspecifications in the Q-matrix for graded response data based on the sequential generalized deterministic inputs, noisy ‘and’ gate (G-DINA) model. The proposed Q-matrix validation procedure is implemented in a stepwise manner based on the Wald test and an effect size measure. The feasibility of the proposed method is examined using simulation studies. Also, a set of data from the Trends in International Mathematics and Science Study (TIMSS) 2011 mathematics assessment is analysed for illustration.
