组织分割供给与工作情绪衰竭的关系:工作心理脱离和工作→非工作冲突的中介作用*

采用问卷调查法,对271名企业管理人员进行调查,探讨了组织分割供给与工作情绪衰竭的关系,以及工作心理脱离和工作→非工作冲突在其中的中介作用。结构方程模型分析表明:(1)组织分割供给不仅可以通过工作→非工作冲突的中介作用负向影响工作情绪衰竭;(2)还可以通过依次影响工作心理脱离和工作→非工作冲突进而负向影响工作情绪衰竭。因此,组织分割供给对个体的非工作角色和工作角色均有积极作用。

Investigating the Impact of Uncertainty About Item Parameters on Ability Estimation

Asymptotic expansions of the maximum likelihood estimator (MLE) and weighted likelihood estimator (WLE) of an examinee’s ability are derived while item parameter estimators are treated as covariates measured with error. The asymptotic formulae present the amount of bias of the ability estimators due to the uncertainty of item parameter estimators. A numerical example is presented to illustrate how to apply the formulae to evaluate the impact of uncertainty about item parameters on ability estimation and the appropriateness of estimating ability using the regular MLE or WLE method.     

Familiarity increases the number of remembered Pokémon in visual short-term memory

Long-term memory (LTM) can influence many aspects of short-term memory (STM), including increased STM span. However, it is unclear whether LTM enhances the quantitative or qualitative aspect of STM. That is, do we retain a larger number of representations or more precise representations in STM for familiar stimuli than unfamiliar stimuli? This study took advantage of participants’ prior rich multimedia experience with Pokémon, without investing on laboratory training to examine how prior LTM influenced visual STM. In a Pokémon visual STM change detection task, participants remembered more first-generation Pokémon characters that they were more familiar with than recent-generation Pokémon characters that they were less familiar with. No significant difference in memory quality was found when quantitative and qualitative effects of LTM were isolated using receiver operating characteristic (ROC) analyses. Critically, these effects were absent in participants who were unfamiliar with first-generation Pokémon. Furthermore, several alternative interpretations were ruled out, including general video-gaming experience, subjective Pokémon preference, and verbal encoding. Together, these results demonstrated a strong link between prior stimulus familiarity in LTM and visual STM storage capacity.     

Dissociations of the number and precision of visual short-term memory representations in change detection

The present study dissociated the number (i.e., quantity) and precision (i.e., quality) of visual short-term memory (STM) representations in change detection using receiver operating characteristic (ROC) and experimental manipulations. Across three experiments, participants performed both recognition and recall tests of visual STM using the change-detection task and the continuous color-wheel recall task, respectively. Experiment 1 demonstrated that the estimates of the number and precision of visual STM representations based on the ROC model of change-detection performance were robustly correlated with the corresponding estimates based on the mixture model of continuous-recall performance. Experiments 2 and 3 showed that the experimental manipulation of mnemonic precision using white-noise masking and the experimental manipulation of the number of encoded STM representations using consolidation masking produced selective effects on the corresponding measures of mnemonic precision and the number of encoded STM representations, respectively, in both change-detection and continuous-recall tasks. Altogether, using the individual-differences (Experiment 1) and experimental dissociation (Experiment 2 and 3) approaches, the present study demonstrated the some-or-none nature of visual STM representations across recall and recognition.     

Automatic thoughts as a predictor of internalizing and externalizing problems in Chinese adolescents: A test of the cognitive content‐specificity hypothesis with age effects

The main aim of the current study was to test the cognitive content‐specificity hypothesis across internalizing and externalizing problems in Chinese adolescents. The participants consisted of 2,158 adolescents aged 11–19 years from three middle schools, and they completed a number of measures assessing a wide range of automatic thoughts and syndromes related to internalizing and externalizing problems. Multivariate regression analyses demonstrated that thoughts about social threats, personal failure and hostility were the strongest predictors of anxiety, depression, and externalizing problems, respectively. Age was a statistically significant, albeit modest, moderator of the relationship between automatic thoughts about social threat and anxiety. The current study provides support for the cognitive content‐specificity hypothesis in internalizing and externalizing problems in a Chinese sample.     

Understanding the Effect of Social Capital on the Depression of Urban Chinese Adolescents: An Integrative Framework

Using data from an ongoing longitudinal study of 5,164 adolescents and their parents from seven cities in mainland China, this study investigated how social capital embedded in the family and the community, together with family human capital and financial capital, influenced the depressive symptoms of urban Chinese adolescents within an integrative framework. The structural equation modeling results suggested that higher community social capital was associated with lower level of adolescent depressive symptoms and was the strongest predictor among all these contextual factors. Family social capital played a significant role in mediating the effects of all other contextual factors on adolescent depressive symptoms. Unexpectedly, higher family financial capital predicted increased depressive symptoms both directly and indirectly through its negative effect on family social capital. As for gender, female adolescents reported more depressive symptoms as a result of less available family social capital. Implications of these findings for theory, practice, policy, and future research are discussed.     

略论“延续性医德教育”模式的内涵与构建

目前医德教育在教育时间与教育手段等方面缺乏延续性。通过对医德教育的特点和规律以及传统医德教育存在的弊病、医疗领域不正之风的负面影响等问题的分析,提出应着手构建在校医学生—实习生—在职医务人员"三位一体"的"延续性医德教育"模式,实现"第一课堂与第二课堂"、"系统医德理论与实践"、"被动性与自主性"医德教育三结合。
