It is frequently assumed that a poor psychosocial working environment will create conditions that encourage bullying. However, few studies have examined this assumption while comparing work environment ratings of bullied and non-bullied employees who work in the same organization and/or department. The objective of this study was to examine the relationship between organizational factors and the incidence of acts of bullying based on two different approaches: the first by comparing bullied with no-bullied, the second by comparing departments with widespread bulling with departments with little bulling. The study was a part of a general survey study of the work environment and employee well-being in 12 different local social security offices. A total of 898 persons participated in the study (a response rate of 88%).
First, the results showed a clear relationship between bullying and fear of organizational change; secondly, weak, but significant, correlations between bullying and other organizational factors; thirdly, the subsequent analyses compared departments in which bullying were most widespread with the rest of the departments. The results supported the hypothesis that departments that suffer from much bullying also have a poorer psychosocial work environment, results that support the assumption that organizational factors such as changes in one's position, pressure of work, performance demands, autocratic management and role conflict and lack of role clarity, as well as a poor social climate can contribute to the emergence of higher incidences of bullying.  相似文献

Personality disorders have a long history in the literature but a short scientific history. The point prevalence of personality disorders is 10%, but the lifetime prevalence is probably 30–40%. Genetic factors contribute to around 40–50% of the variation in the development of personality disorders. The effect of shared environment is very small or non‐existent. Some researchers have tried to promote gene‐environment interaction. However, in reality, the studies investigated gene‐situation interaction, as the “environment” may in reality be partly of a genetic nature. Thus, we are dealing with an unknown part of gene‐gene interaction. Gene‐experience (not gene‐environment) correlations are the rule in human life. Personality disorders co‐occur (are comorbid) with symptom disorders (Axis I) and correlate with common personality dimensions. Possibly, the concept of personality disorder could merge with dysfunctional personality types. But it is likely that the concept will survive on its own.  相似文献

The obesity epidemic has widened the aims of prevention research to include the influence of local food environments on health outcomes. This mixed methods study extends existing research focused on local food environments by examining whether community members’ find food accessible. Data from food store audits and one-on-one interviews were analyzed. Results reveal that most of the food stores surrounding the three research sites were convenience stores and non-chain grocery stores; interviewees did not perceive these stores to be “real” food stores. Tobacco and alcohol products were more prevalent in the food stores than all varieties of milk, fresh fruits, or fresh vegetables. Food access varied by site in a manner that was designed to appeal to customers’ race, class, gender, or environment. Findings reveal that local food environments are reflections of social hierarchies. Unraveling the politics of space ought to be a part of broader efforts to promote the public’s health.  相似文献

Animals depleting one patch of resources must decide when to leave and switch to a fresh patch. Foraging theory has predicted various decision mechanisms; which is best depends on environmental variation in patch quality. Previously we tested whether these mechanisms underlie human decision making when foraging for external resources; here we test whether humans behave similarly in a cognitive task seeking internally generated solutions. Subjects searched for meaningful words made from random letter sequences, and as their success rate declined, they could opt to switch to a fresh sequence. As in the external foraging context, time since the previous success and the interval preceding it had a major influence on when subjects switched. Subjects also used the commonness of sequence letters as a proximal cue to patch quality that influenced when to switch. Contrary to optimality predictions, switching decisions were independent of whether sequences differed little or widely in quality.  相似文献

Kelly, Avraamides和Loomis (2007)发现被试在新环境中空间更新失败, 而肖承丽和刘传军(2014)发现被试在新环境中可使用想象平移等策略来实现空间更新。为了探索该两项研究的异同, 本研究采用与Kelly等相同的实验范式进行研究。实验1被试在原学习环境中完成实验任务。实验2被试记忆完物体空间位置后, 转移至新环境, 在只依靠离线表征、离线表征与在线表征相协调和离线表征与在线表征相矛盾三种条件下完成相同的实验任务。结果发现, 被试在原环境中通过躯体运动和记忆两种方式促进空间更新, 具有同等有效性, 而在新环境中躯体运动显著差于记忆对空间更新的促进作用; 躯体运动和记忆对空间更新的促进作用在两种环境中均高度相关。研究表明, 躯体运动促进空间更新具有环境依赖效应, 与记忆对空间更新的促进作用相比, 躯体运动对空间更新的促进作用会随着环境的改变而降低。  相似文献

气质的稳定性和发展性是心理学研究争论已久的问题。遗传×环境的研究视角再次打破了传统研究模式,取而代之的是气质稳定性与发展性的共存,遵循传统先天论——环境论——先天论——先天论×环境论的总体发展态势。该视角在拓展气质研究领域的同时,也成为未来研究的主要取向。本文首先综述了由于研究手段的更新和多元化而引发的气质稳定性和发展性两方面的最新实证研究,探讨了稳定性中遗传基因加性效应和非加性效应、脑生理基础以及个体气质发展性的内部、外部影响因素。然后,从研究样本的年龄段、气质的生理机制和儿童气质的纵向研究、亲子互动及师生互动方面的研究等方面提出目前我国气质研究未来方向。  相似文献

In this paper we review literature on the use of the HOME Inventory across cultures. We address issues pertaining to measurement equivalence and validity. Specifically, we focus on: (a) changes in the content of HOME made by researchers, (b) distributional properties of HOME scores, (c) the factor structure of HOME, and (d) correlations between HOME, family characteristics, child characteristics and environmental conditions. In most affluent, western countries, with their individualist orientations, HOME was used essentially as it was originally constructed. Researchers in less industrialized, more collectivist countries tended to express greater scepticism about the appropriateness of some HOME items, and several teams of researchers made modifications in the instrument. The HOME total score showed theoretically meaningful (and similar) correlations with family structure, family status and child outcome measures across many cultures. Evidence attesting to the cultural equivalence (and validity) of HOME subscales was far less plentiful and compelling. In general, there seemed greater cross-cultural equivalence for items assessing cognitively stimulating aspects of the environment than for items assessing socioemotional support. The usefulness of the Inventory in other cultures and for cross-cultural comparisons depends on the purposes one has for using a measure of the home environment. © 1996 John Wiley & Sons, Ltd.  相似文献

论情绪的生态理性   总被引:6,自引:0,他引:6  
生态理性强调环境对人的塑造作用,强调人在适应环境过程中获得的功能作用.该文在全面解读生态理性内涵的基础上,从两个方面寻找证据论证情绪具有生态理性:(1)情绪是环境自然塑造的结果,携带着丰富的环境信息;(2)情绪的功能反映环境结构,自动调节人类行为。在上述论证的基础上,我们尝试提出情绪影响个体行为的工作机制,并在一定范围内分析了不良情绪与生态理性之间的关系。  相似文献

Background and objectives: Although it has been postulated that psychological responses to stress in adulthood are grounded in childhood experiences in the family environment, evidence has been inconsistent. This study tested whether two putative measures of neurobiological sensitivity (vagal flexibility and attentional capacity) moderated the relation between women’s reported exposure to a risky childhood environment and current engagement in suppressive or avoidant coping in response to daily stress.

Design and methods: Adult women (N?=?158) recruited for a study of stress, coping, and aging reported on early adversity (EA) in their childhood family environment and completed a week-long daily diary in which they described their most stressful event of the day and indicated the degree to which they used suppression or avoidance in response to that event. In addition, women completed a visual tracking task during which heart rate variability and attentional capacity were assessed.

Results: Multilevel mixed modeling analyses revealed that greater EA predicted greater suppression and avoidance only among women with higher attentional capacity. Similarly, greater EA predicted greater use of suppression, but only among women with greater vagal flexibility.

Conclusion: Childhood adversity may predispose individuals with high neurobiological sensitivity to a lifetime of maladaptive coping.  相似文献

Most studies on the evaluation of teaching focus on the input (teacher traits) or the output (student-generated products) of the teaching and learning processes. This article is based on a case study that examines the three components of teaching and learning: input, output and process. It presents a framework for collecting quantitative and qualitative data on the quality of instruction, assessment and feedback, and learning environment in college composition courses to complement the feedback provided by the end-of-course student evaluations of teaching for the purpose of monitoring, guiding, and improving instruction.  相似文献
