Abstract

Research suggests that there are substantial differences in the ways in which people cope with strcss, and that certain coping strategies buffer the degree of psychological and physical illness resulting from stress. Furthermore, personality, the situational context and subjective appraisal of the situation are believed to mediate coping behaviour and its effectiveness. The present investigation reports the results of two studies of the relationship between coping behaviour and the personality disposition need for power, taking into account the environment and the subject's appraisal of the situation. Highly power-motivated individuals were hypothesized to utilize emotion-focused coping strategies more than problem-focused coping strategies, to find the training environment stressful and anxietyprovoking, and to report more illness, than low power-motivated individuals. A 19-wcck policc academy training programme was used to measure these relationships in 34 police trainees. Thc results did not support all hypotheses. Findings are discussed with reference to sample characteristics, training intensity, and the empirical work in this area.  相似文献

While global polio eradication requires tremendous efforts in countries where wild polioviruses (WPVs) circulate, numerous outbreaks have occurred following WPV importation into previously polio‐free countries. Countries that have interrupted endemic WPV transmission should continue to conduct routine risk assessments and implement mitigation activities to maintain their polio‐free status as long as wild poliovirus circulates anywhere in the world. This article reviews the methods used by World Health Organization (WHO) regional offices to qualitatively assess risk of WPV outbreaks following an importation. We describe the strengths and weaknesses of various risk assessment approaches, and opportunities to harmonize approaches. These qualitative assessments broadly categorize risk as high, medium, or low using available national information related to susceptibility, the ability to rapidly detect WPV, and other population or program factors that influence transmission, which the regions characterize using polio vaccination coverage, surveillance data, and other indicators (e.g., sanitation), respectively. Data quality and adequacy represent a challenge in all regions. WHO regions differ with respect to the methods, processes, cut‐off values, and weighting used, which limits comparisons of risk assessment results among regions. Ongoing evaluation of indicators within regions and further harmonization of methods between regions are needed to effectively plan risk mitigation activities in a setting of finite resources for funding and continued WPV circulation.  相似文献

Detecting agency problems is an important task when assessing the effectiveness of a nonprofit organization's governance. A first step is to examine the objectives of principals and agents and determine whether there is a systematic difference between them. Using a discrete choice experiment, we identify the objectives of board chairpersons (principals) and headmasters (agents) of Flemish nonprofit schools. We find systematic differences between the two groups. Of the seven possible objectives set out in the experiment, six are relevant for both headmasters and board chairpersons. For four of these, the preferences of both groups differ significantly. Whereas ideological values play an important role for both the board and the headmaster, they are significantly more important for the board. Both parties dislike having a large number of pupils, and the disutility is larger for the board. With respect to job satisfaction and pupil satisfaction, we find the opposite: while the board is prepared to give up pupil and job satisfaction in favor of the other objectives, these two objectives score very high on the priority list of the headmasters.  相似文献

The developmental origins of sharing remain little understood. Using procedures adapted from research on prosocial behavior in chimpanzees, we presented 18- and 25-month-old children with a sharing task in which they could choose to deliver food to themselves only, or to both themselves and another person, thereby making it possible for them to share without personal sacrifice. The potential recipient, a friendly adult, was either silent about her needs and wants or made them explicit. Both younger and older toddlers chose randomly when the recipient was silent. However, when the recipient vocalized her desires 25-month-olds shared whereas younger children did not. Thus, we demonstrate that children voluntarily share valued resources with others by the end of the second year of life, but that this depends on explicit communicative cues about another's need or desire.  相似文献

Repositioning mothers: mothers,disabled children and disability studies   总被引:1,自引:0,他引:1  
In this article we set out to review the ways in which mothers of disabled children have been portrayed within disability studies and the more broader academic literature. We argue that within disability studies mothers of disabled children occupy a liminal position because they are often not disabled and yet they can experience forms of disablism. Their experiences can differ markedly from the experiences of mothers of non‐disabled children and yet the consequences and outcomes of these experiences, such as developing a ‘special competence’ is largely overlooked. Mothers can work to effect change on behalf of their children and, in some cases, for disabled people more generally, however, this role of activist mother is largely undervalued. The review of literature presented here leads us to conclude that further research needs to be undertaken exploring and highlighting the ways in which mothers of disabled children negotiate, manage and approach their daily lives, operating within what are described by feminist scholars as oppressive mothering ideologies and disabling environments.  相似文献
