From 1985-2000, unemployment was the strongest correlate of Japanese suicide rates.     

Factors Moderating Children's Adjustment to Parental Separation: Findings From a Community Study in England

Research findings show that there is marked variability in children's response to parental separation, but few studies identify the sources of this variation. This prospective longitudinal study examines the factors modifying children's adjustment to parental separation in a community sample of 5,635 families in England. Children's behavioral/emotional problems were assessed when children were aged 47 and 81 months; marital quality, maternal depression, socioeconomic circumstances, and demographic variables were assessed prior to the separation from maternal report. Results indicated that 346 mothers separated from their partners in the 3-year period. Preseparation differences were found for measures of family process and parent risk factors, with effect sizes ranging from small to trivial. Parental separation was associated with a significant but modest increase in behavioral/emotional problems, independent of marital quality, maternal depression, socioeconomic circumstances, and demographic variables. Moderation analyses showed that children of cohabiting parents had a greater increase in adjustment problems following parental separation than children of married parents. Further research elucidating the factors that moderate children's adjustment to parental separation is needed to improve our understanding of who may most likely benefit from preventive interventions.     

Gaze allocation in a dynamic situation: effects of social status and speaking

Human visual attention operates in a context that is complex, social and dynamic. To explore this, we recorded people taking part in a group decision-making task and then showed video clips of these situations to new participants while tracking their eye movements. Observers spent the majority of time looking at the people in the videos, and in particular at their eyes and faces. The social status of the people in the clips had been rated by their peers in the group task, and this status hierarchy strongly predicted where eye-tracker participants looked: high-status individuals were gazed at much more often, and for longer, than low-status individuals, even over short, 20-s videos. Fixation was temporally coupled to the person who was talking at any one time, but this did not account for the effect of social status on attention. These results are consistent with a gaze system that is attuned to the presence of other individuals, to their social status within a group, and to the information most useful for social interaction.     

Developing a screening instrument and at-risk profile for nonsuicidal self-injurious behavior in college women and men

Archival data (N = 1,048 women, 1,136 men) from a mental health survey of college students were used to investigate incidence of nonsuicidal self-injury (NSSI), including cutting. Significant levels (defined as 4-5 lifetime incidents) were found in 9.3% of women and 5.3% of men. The Counseling Center Assessment for Psychological Symptoms (a global symptom inventory) and an assessment of trauma had been field tested with this sample. We randomly partitioned half of these data into a holdout sample and used the remainder to develop an NSSI screening inventory that included (a) 5 women's screening items, including 1 item to assess trauma experienced; (b) 11 men's screening items; and (c) 12 items common to men and women, including depression, dissociation, anger, unwanted thoughts, nightmares or flashbacks, and having witnessed trauma. Logistic regression and receiver-operating characteristic curve analysis suggested the inventory significantly discriminated NSSI men and women in the holdout sample, p < .001. Cutoff scores were identified to correctly classify about 48% of the true positive male and female NSSI cases, with false positive rates of 13.2% and 8.4% for women and men, respectively.     

Determinants of Standard Errors of MLEs in Confirmatory Factor Analysis

This paper studies changes of standard errors (SE) of the normal-distribution-based maximum likelihood estimates (MLE) for confirmatory factor models as model parameters vary. Using logical analysis, simplified formulas and numerical verification, monotonic relationships between SEs and factor loadings as well as unique variances are found. Conditions under which monotonic relationships do not exist are also identified. Such functional relationships allow researchers to better understand the problem when significant factor loading estimates are expected but not obtained, and vice versa. What will affect the likelihood for Heywood cases (negative unique variance estimates) is also explicit through these relationships. Empirical findings in the literature are discussed using the obtained results.     

Quasicrystalline Al-Fe phase formed by ion mixing

Abstract

A quasicrystalline Al-Fe phase has been formed by room-temperature ion mixing of AI-Fe multiple layers with no additional postannealing. The quasicrystalline phase was dispersed as grain in an amorphous matrix. The size of the grains was about 10-30nm, and the composition was determined to be Al₈₀Fe₂₀. The structure of the quasicrystalline phase was identified by calculating some 20 sharp diffraction rings in the selected-area diffraction pattern and found to be similar to that of the rapidly quenched AI-Mn quasicrystalline phase.     

The Process Mechanisms Linking Recruiter Positive Moods and Organizational Attraction

The main purpose of this study is to investigate the mechanisms through which recruiters' positive moods lead to organizational attraction. Participants consisted of 161 applicant–recruiter dyads from 55 companies in Taiwan. Results show that recruiters' felt positive moods were positively related to applicant's perceptions of informativeness and competence, which, in turn, influenced organizational attraction. In addition, recruiters felt that positive moods were positively related to their display of positive moods, which were positively related to applicant's positive moods, which, in turn, affected organizational attraction.     

情绪取向理论建构及实证

该研究尝试用一种新的视角一取向研究视角,对以往情绪理论进行整合研究,建构一种与社会情境结合更紧密,更具概括性的情绪取向理论.情绪取向理论的假设建构模型包括四个维度:理性取向、感性取向、积极取向和消极取向.根据理论模型编制情绪取向量表,以779名被试为研究对象,运用探索性因素分析和验证性因素分析方法对该理论模型进行实证研究.结果证明了该理论建构的存在,理论建构中各维度的因素负荷和拟合指数良好,情绪取向量表具有良好的信度和建构效度.
