Early postweaning experience in an enriched environment had a greater influence on the open-field behavior and body weight of wild Norway rats than of their domestic counterparts. Genetic changes accompanying the domestication process may have reduced the relative impact of postweaning experience on the development of the domestic rat's response to changes in its environment.  相似文献

A 2×2×2 factorial design was employed to examine the influence of instructed leadership style, sex of leader, and sex of followers on leader behavior, subordinate satisfaction, and productivity in a simple task. In general, male and female leaders were equally able and equally willing to display autocratic and democratic leadership styles if so instructed. Similarly, leader sex did not have a significant influence on subordinate satisfaction or productivity either by itself or in interaction with leadership style or follower sex.  相似文献

Findings from 55 psychological autopsies of decedents who perished on U.S. railroad rights‐of‐way between October 1, 2007, and September 30, 2010 are reported. Described are distal, proximal, and contextual factors of risk; understandings of why these suicides occurred on railroad rights‐of‐way; and opportunities for prevention of similar suicides. International comparisons of suicides on railroad rights‐of‐way are made to highlight distinct findings regarding U.S. cases. Decedents studied exhibited considerable predisposing risk for suicide, with a high prevalence of severe mental disorders and substance abuse. In addition, a number of acute risk factors were commonly observed, notably suicide ideation, hopelessness, anxiety, and anger. In the context of that acute risk, associated situational variables and a relative absence of protective factors are described.  相似文献

This paper explores how sustainability has been integrated into and communicated in Canadian Master’s of Business Administration (MBA) programs. We content analyzed university, business school, and MBA program mission and values statements; communicated strategic priorities; and relevant academic calendar content, as well as sustainability rankings and select media depictions of sustainable MBA programs and practices. We explore the potential for greenwashing practices in relation to the integration of sustainability in business education. We found some evidence of a decoupling between university and/or business school mission and claims, and MBA policies and practices. We conclude with a discussion of our findings, study limitations and some relevant implications for academia.  相似文献

Abstract

Although open-mindedness is generally valued, people are not equally open-minded in all situations. Open-mindedness is viewed as socially desirable when individuals encounter viewpoints that are compatible with conventional social norms. However, open-mindedness is viewed in less desirable terms when individuals encounter viewpoints that undermine these norms. The perceived desirability of open-mindedness is also influenced by the individual’s personal attitudinal convictions. Individuals ‘inflate’ the normative appropriateness of open-mindedness when it serves to reinforce their convictions, but devalue the normative appropriateness of open-mindedness when it serves to contradict these convictions. Conversely, normative prohibition of closed-mindedness is exaggerated when a closed-minded orientation threatens the individual’s personal attitudinal convictions, but is minimized (or reversed) when a closed-minded orientation reinforces these convictions. Paradoxically, the perceived appropriateness of open-mindedness is engendered (at least in part) by the motivation to confirm one’s prior attitudinal convictions. Evidence of this attitude justification effect is obtained in two experiments.  相似文献

The separate and combined efficacy of a social norms and a self-affirmation intervention to motivate decreased sugar-sweetened beverage (SSB) consumption was examined in 2 experiments. College students were randomly assigned to receive information about SSB consumption risks, norms, both, or neither. In addition, participants performed either a self-affirmation or control task. Self-affirmation only weakly affected SSB consumption intentions and behaviors. However, participants in Experiment 2 who received risks information, norms information, or both reported greater SSB reduction intentions than did those who received no information. Two weeks later, those who received both types of information reported more frequent behavior change preparations, and it appears this effect may have been partially mediated by the changes in intentions to reduce SSB consumption.  相似文献

Predictors of the physical and relational aggressive behavior of children in foster care were examined (N?=?160, 50.9% male, M age?=?7.57, SD?=?2.39). First, predictors representative of children’s placement histories were examined in relation to the children’s aggression at T1. Next, predictors representing characteristics of the current family environment were examined in relation to the children’s aggression at T2 (4 months later). Results revealed that a greater number of prior group home placements and being in a non-kinship home were associated with higher physical aggression at T1. A greater number of prior group home placements, a fewer number of regular home placements, being in a non-kinship home, and prior removal from the home due to neglect were associated with higher relational aggression at T1. The results also revealed that higher foster sibling relational aggression at T1 predicted lower child physical aggression at T2. If foster siblings were biological children of the foster parent, higher levels of a foster sibling’s physical aggression at T1 predicted reduced child physical aggression at T2. The opposite pattern was observed if foster siblings were not biological children of the foster parent. Lastly, longer time in the current placement, more children in the home, and the presence of a sibling that was a biological child of the parent predicted higher child relational aggression at T2. These findings provide initial insights into how placement history and current family environment are associated with the physical and relational aggressive behavior of children in foster care.  相似文献

With the present data, we explored the relations between the language of interviewer questions, children's reports, and case and child characteristics in forensic interviews. Results clearly indicated that the type of questions posed by interviewers—either probing generic or episodic features of an event—was related to the specificity of information reported by children. Further, interviewers appeared to adjust their questioning strategies based on the frequency of the alleged abuse. Children alleging single instances of abuse were asked more episodic questions than those alleging multiple abuses. In contrast, children alleging multiple incidents of abuse were asked a greater proportion of generic questions. Given that investigators often seek forensically relevant episodic information, it is recommended that training for investigators focus on recognition of prompt selection tendencies and developing strategies for posing non‐suggestive, episodically focused questions.

Based on a study conducted in a large corporation (XINC, a pseudonym) and other research, it appears that performance management can be used to increase levels of employee engagement. We begin this article with a discussion of employee engagement, define engaged employees as those who feel involved, committed, passionate, and empowered, and demonstrate those feelings in work behavior. We then discuss an expanded view of performance management, conceptualizing it as five major activities that serve to organize relevant behaviors shown to be either direct or indirect predictors of employee engagement in the study at XINC. These major activities include setting performance and development goals, providing ongoing feedback and recognition, managing employee development, conducting mid-year and year-end appraisals, and building a climate of trust and empowerment. In turn, we briefly discuss how each of these major activities contributes to employee engagement, suggest which activities benefit from further research, and recommend possible studies. Although there is evidence for performance management as a driver of employee engagement, we conclude there is a need for additional research that clarifies for managers which of these activities have the strongest impact on employee engagement.  相似文献
