The present study applied two theoretical frameworks (the demands–control–support model and the conservation of resources model) to investigate associations between job demands, job burnout, and counterproductive work behaviors (CWB) in the context of social support and job control. Data were collected among 625 police officers. Moderated mediation analysis showed that high job demands were indirectly related to high CWB, with job burnout acting as the mediator. These indirect effects were moderated by work-related resources (social support and job control). Job demands were associated with higher job burnout when social support was low. High job burnout was related to more frequent CWB when support was low and control was high. Finally, the job demands–CWB association was significant when support was low and control was high.  相似文献

In the context of some personal control (mastery) theories (e.g., J. Heckhausen & R. Schultz, 1995; Gutmann, 1964), primary, secondary, and tertiary personal control of development among subjects in three transitional periods of life were investigated (D. J. Levinson, C. N. Darrow, E. B. Klein, M. H. Levinson, & B. McKee, 1978). Results confirmed the expectation that primary control decrease whereas secondary control increase with age. Tertiary control was the same in all transitional periods. There were some differences in contribution of predictors of primary control in the early, middle, and late period of transition. From the group of variables relating to personality traits, optimism proved a good predictor of primary control in the young and middle aged, whereas in old people who have the lowest primary control, none of the personality traits proved predictive. The importance of goals related to knowledge and competence (GKC) was a significant predictor in all three (age) groups.  相似文献

Despite the impact of the COVID-19 outbreak being largely negative on parents and children, for some families, lockdown could also bring about some positive effects, for example, increased emotional closeness, and more time for joint activity. The aim of the current study was to investigate cross-sectionally the most important correlates of the positive experiences in the parent–child relationship among Polish mothers and fathers during the lockdown in the initial phase of the COVID-19 outbreak. In May 2020, 228 mothers and 231 fathers completed the Brief version of the Empathic Sensitivity Questionnaire, Difficulties in Emotion Regulation Scale Short Form, Social Support Scale, Parenting Self-Agency Measure, and Scale of Positive Experiences in Parent–Child Relationship during the COVID-19 lockdown. Our results showed that parenting self-efficacy and social support were the strongest correlates of positive experiences in the parent–child relationship in both mothers and fathers during the lockdown. Perspective-taking was positively related to the positive experiences in mothers, whereas personal distress was positively associated with the positive experiences in the parent–child relationship in fathers. Our results point to factors of potential importance in designing preventive and therapeutic interventions for mothers and fathers to enhance positive experiences in the parent–child relationship during the pandemic.  相似文献

从科学认识的过程看中药指纹图谱技术的发展历程   总被引:1,自引:0,他引:1  
中药指纹图谱是一种通过色谱峰反映中药成分和综合效应的分析手段,具有整体性和稳定性的特点,能较全面地反映中药的质量,现已成为现代中药质控的发展趋势。但其研究仍属初级阶段,如何准确地解析“谱”与“效”的关系及减少中药质量的不稳定性对图谱构建的影响,尚待进一步探索与研究。  相似文献

Emotionally charged pictorial materials are frequently used in phobia research, but no existing standardized picture database is dedicated to the study of different phobias. The present work describes the results of two independent studies through which we sought to develop and validate this type of database—a Set of Fear Inducing Pictures (SFIP). In Study 1, 270 fear-relevant and 130 neutral stimuli were rated for fear, arousal, and valence by four groups of participants; small-animal (N = 34), blood/injection (N = 26), social-fearful (N = 35), and nonfearful participants (N = 22). The results from Study 1 were employed to develop the final version of the SFIP, which includes fear-relevant images of social exposure (N = 40), blood/injection (N = 80), spiders/bugs (N = 80), and angry faces (N = 30), as well as 726 neutral photographs. In Study 2, we aimed to validate the SFIP in a sample of spider, blood/injection, social-fearful, and control individuals (N = 66). The fear-relevant images were rated as being more unpleasant and led to greater fear and arousal in fearful than in nonfearful individuals. The fear images differentiated between the three fear groups in the expected directions. Overall, the present findings provide evidence for the high validity of the SFIP and confirm that the set may be successfully used in phobia research.  相似文献

As a result of the increasing role of online advertising and strong competition among advertisers, intrusive techniques are commonly used to attract web users’ attention. Moreover, since marketing content is usually delivered to the target audience when they are performing typical online tasks, like searching for information or reading online content, its delivery interrupts the web user’s current cognitive process. The question posed by many researchers in the field of online advertising is: how should we measure the influence of interruption of cognitive processes on human behavior and emotional state? Much research has been conducted in this field; however, most of this research has focused on monitoring activity in the simulated environment, or processing declarative responses given by users in prepared questionnaires. In this paper, a more direct real-time approach is taken, and the effect of the interruption on a web user is analyzed directly by studying the activity of his brain. This paper presents the results of an experiment that was conducted to find the brain activity patterns associated with interruptions of the cognitive process by showing internet advertisements during a text-reading task. Three specific aspects were addressed in the experiment: individual patterns, the consistency of these patterns across trials, and the intra-subject correlation of the individual patterns. Two main effects were observed for most subjects: a drop in activity in the frontal and prefrontal cortical areas across all frequency bands, and significant changes in the frontal/prefrontal asymmetry index.  相似文献

In the two experiments reported here, we uncovered evidence for shared structural representations between arithmetic and language. Specifically, we primed subjects using mathematical equations either with or without parenthetical groupings, such as 80 - (9 + 1) × 5 or 80 - 9 + 1 × 5, and then presented a target sentence fragment, such as "The tourist guide mentioned the bells of the church that . . .," which subjects had to complete. When the mathematical equations were solved correctly, their structure influenced the noun phrase--for example, either "the bells of the church" or "the church," respectively--that subjects chose to attach their sentence completion to. These experiments provide the first demonstration of cross-domain structural priming from mathematics to language. They highlight the importance of global structural representations at a very high level of abstraction and have potentially far-reaching implications regarding the domain generality of structural representations.  相似文献

We conducted a study to examine the impact of motivation and length of delay on performance on prospective memory (PM) tasks in 2-year of children. A total of 158 children aged exactly 24 months were asked to perform a naturalistic PM task. Length of delay (10?min; 35?min) and motivation (high; very high) were between-subjects factors. Two thirds of children had to be excluded from the analysis because of poor retrospective memory for the PM task instructions which were no longer remembered at the end of the session. For the children who did remember the instructions, both motivation and delay had significant effects on PM. Also, their PM performance was reliably above zero, even after the long delay. The findings indicate that when children as young as 24 months are able to remember the PM task instructions they can reliably succeed in PM tasks that are intrinsically motivating for them.  相似文献
