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.

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.     

Customer-Initiated Support and Employees’ Proactive Customer Service Performance: A Multilevel Examination of Proactive Motivation as the Mediator

Drawing on the proactive motivation model and theories of motivation, the current study examined customer-initiated support as an antecedent of employees’ proactive customer service performance (PCSP) and investigated the mediating role of proactive motivations and the moderating role of serving culture. We conducted two multilevel studies to test the proposed hypotheses. In study 1, we collected diary data from 158 nurses across 10 working days, and results showed that the relationship between nurses’ daily experience of customer-initiated support and their PCSP was mediated by self-efficacy, work meaning, and positive affect. In study 2, we collected multilevel multi-source data from 373 nurses nested within 80 units and found that nurses’ experience of customer-initiated support was positively related to their supervisor-rated PCSP via role-breadth self-efficacy and work meaning, but not through positive affect. Further, team-level serving culture strengthened the positive relationship between customer-initiated support and role-breadth self-efficacy. These findings shed light on understanding the effect of customer-initiated support as an external factor on prompting service employees’ proactive behaviors, potential motivational mediators to explain the underlying mechanisms, and potential boundary conditions inside of service organizations to strengthen the positive effects of customer-initiated support.     

How Do Artificial Neural Networks Classify Musical Triads? A Case Study in Eluding Bonini's Paradox

How might artificial neural networks (ANNs) inform cognitive science? Often cognitive scientists use ANNs but do not examine their internal structures. In this paper, we use ANNs to explore how cognition might represent musical properties. We train ANNs to classify musical chords, and we interpret network structure to determine what representations ANNs discover and use. We find connection weights between input units and hidden units can be described using Fourier phase spaces, a representation studied in musical set theory. We find the total signal coming through these weighted connection weights is a measure of the similarity between two Fourier structures: the structure of the hidden unit's weights and the structure of the stimulus. This is surprising because neither of these Fourier structures is computed by the hidden unit. We then show how output units use such similarity measures to classify chords. However, we also find different types of units—units that use different activation functions—use this similarity measure very differently. This result, combined with other findings, indicates that while our networks are related to the Fourier analysis of musical sets, they do not perform Fourier analyses of the kind usually described in musical set theory. Our results show Fourier representations of music are not limited to musical set theory. Our results also suggest how cognitive psychologists might explore Fourier representations in musical cognition. Critically, such theoretical and empirical implications require researchers to understand how network structure converts stimuli into responses.     

Family Socioeconomic Status and Social Media Addiction in Female College Students: The Mediating Role of Impulsiveness and Inhibitory Control

Abstract

There is increasing evidence that low family socioeconomic status (SES) not only is a social issue, but also is a precursor to addiction to social media and other technologies. The authors investigated the relationship between family SES, stress, impulsiveness and inhibitory control, and social media addiction among Chinese female college students. The findings revealed that in lower-SES families, increased social media addiction was associated with reduced inhibitory control and increased stress and impulsiveness. A structural equation model was used to examine the mediation model hypothesis, and the results confirmed the mediating role of no-planning impulsiveness and inhibitory control between family educational level and social media addiction among Chinese female college students. These findings demonstrate the importance of reducing impulsiveness and improving inhibitory control for preventing social media addiction in female college students of low SES. Future studies are required to confirm precursors to social media addiction, elucidate causal mechanisms, and support the explanatory model of social media addiction.
