After outlining a taxonomy of perspectives on social support, the literature on the direct and buffer effects of social support with respect to occupational stress is reviewed. It is noted that negative direct and buffer effects of support are frequently observed. Methodological and theoretical explanations for these contradictory findings are presented. It is argued that a different methodological approach is needed to examine such explanations. Three studies-among police officers, secretaries, and correctional officers-are briefly described in which the Daily Interaction Record in Organizations (DIRO) was used. With this event-contingent recording method, social interactions and stressful events are assessed over a period of 5 days, allowing the detailed examination of the processes involved in supportive interactions, and of the effects of such processes.  相似文献

In this article, the exponentiated Weibull distribution is extended by the Marshall-Olkin family. Our new four-parameter family has a hazard rate function with various desired shapes depending on the choice of its parameters and, thus, it is very flexible in data modeling. It also contains two mixed distributions with applications to series and parallel systems in reliability and also contains several previously known lifetime distributions. We shall study some basic distributional properties of the new distribution. Some closed forms are derived for its moment generating function and moments as well as moments of its order statistics. The model parameters are estimated by the maximum likelihood method. The stress–strength parameter and its estimation are also investigated. Finally, an application of the new model is illustrated using two real datasets.  相似文献

The present study sought to examine the underpinnings of impaired strategic decision-making under stress. In contrast to previous laboratory-based research, we conducted a quasi-experiment in a real life stress situation. Specifically, we used the beauty contest game and compared the performance of a group of participants who were exposed to a real-life stressor (waiting to attend an exam at a university class) with a control group of participants who were not exposed to stress (waiting to attend a regular lecture at a university class). Furthermore, about half of the participants were instructed to write down what they believed another participant had assumed the average number in the beauty contest game to be and which target number she (or he) had chosen accordingly. The results showed that stress impaired strategic reasoning in the beauty contest game. Importantly, even when only including participants who understood the rules of the game in the analyses, stress still increased the numbers chosen in the beauty contest. Furthermore, we found that participants in the stress condition were significantly less likely to base their chosen number on their belief about other players’ choices. Hence, stress not only impairs understanding of the math behind the beauty contest game but also the degree of strategizing per se.  相似文献

Competition is ubiquitous in economic life. Yet, negative consequences of competitive environments have been reported and everyday experience suggests that competitive situations can be very stressful. It is, however, an open question whether or not economic competitions in the laboratory indeed elicit physiological stress reactions. Our study examined subjectively perceived stress and physiological changes induced by a well-established economic laboratory competition paradigm (first used in Niederle & Vesterlund, 2007) in a mixed-gender sample of 111 healthy participants. A mental arithmetic task was performed first under a piece rate (i.e., non-competitive) payment scheme and afterwards under a tournament condition. In a third round, participants decided how to be paid (i.e., piece rate or tournament). Our results indicate that compared to a control group, which performed only the non-competitive condition, the competitive game condition elicited subjective and physiological reactions that are indicative of mild stress, i.e., an increase in heart rate and a decrease of calmness and mood. Furthermore, reactions that are thought to reflect an active coping style were related to the self-selection into competition in the third round of the game. We speculate that real-life economic competitions might be even stronger stressors and the way how people cope with this kind of stress might be related to competitiveness in real-life economic contexts.  相似文献

In recent years, the attention of French public opinion has been focused on the noxious effects of new ways of organizing work. Stress, “suffering”, burnout, psychosocial risks and suicides are topics that have brought experts, the media and politicians into action. What do the social sciences have to say about this? Among the several reactions presented, the principal contrast arises between those who analyze the ills of work as “social constructions” and those who see them as the implications of a trend toward intensifying job-related activities.  相似文献

The pressure to increase productivity is driving many industries to automate. By the year 2000 experts foresee that the VDT will be as common as the telephone is today on the desks of office workers. Just as the mechanization of farm and factory work changed our society and economy in the past, so will the automation of white-collar work influence and change the work process and society. This paper will explore the productivity, cultural, health and mental health issues of office automation. We also discuss the role EAP's can play to help business ameliorate or avoid potential problems associated with the darker side of office automation.  相似文献

BackgroundAnxiety and depression affects many pregnant women. Massage may be beneficial for supporting mental wellbeing during this time. The aim of this study was to assess the feasibility and acceptability of a partner-delivered relaxation massage program for pregnant women, and its impact on symptoms of antenatal anxiety, stress and depression.MethodsA feasibility randomised controlled trial was conducted to compare partner-delivered relaxation massage (intervention) with self-directed stress management (control). Women attended an initial workshop at 28–32 weeks gestation followed by completion of a self-directed massage or stress management program. Qualitative data about the feasibility and acceptability (primary outcomes) were collected via online participant diaries and post-birth interviews. Anxiety, depression and stress symptoms (secondary outcomes) were assessed using the Depression and Anxiety Stress Scale (DASS-21). Birth outcomes were collected at the post- birth interview.ResultsA total of 14 women/partner dyads in the massage group and 13 women in the self-directed stress management group, attended the initial workshops. When interviewed, participants from both groups reported that the programs were feasible and acceptable. Women’s mean scores on all subscales of the DASS-21significantly decreased over time in both the intervention and the control group.ConclusionPregnant women found the partner-delivered massage program to be feasible and acceptable. Both programs decreased women’s symptoms of anxiety, depression and stress with no significant differences identified between the two groups. An adequately powered experimental study with a large representative sample is needed to determine whether partner-delivered relaxation massage reduces pregnant women’s symptoms of anxiety, depression and stress.  相似文献

BackgroundPregnant women with complications including pregnancy-induced hypertension (PIH) and gestational diabetes mellitus (GDM) often experience disrupted sleep patterns because of activation of the sympathetic nervous system. These pathologies are aggravated by sympathetic nervous system activation and may be related to stress. The present study aimed to clarify the characteristics of and changes in sleep quality and stress in pregnant women with PIH and GDM during the second and third trimesters.MethodsWe enrolled 56 women in their second or third trimesters who were diagnosed with PIH or GDM. Participants completed questionnaires, including the Pittsburgh Sleep Quality Index (PSQI) and the Perceived Stress Scale (PSS). Secretory immunoglobulin A (SlgA) concentrations were measured as a biological indicator of stress.ResultsPSS scores and subjective stress parameters were significantly higher than those reported from previous studies of healthy pregnant women (15.2 points and 15.1 points for the second and third trimesters, respectively).Mean one-day values for SIgA were 168.3 and 205.7 μg/mL for the second and third trimesters, respectively. During the second and third trimesters, SIgA scores were higher than those reported for healthy pregnant women in previous studies. The PSQI component scores sleep disturbance (C5) and sleep duration (C3) in follow up case were significantly higher in the third trimester than in the second trimester.DiscussionThis investigation suggests that pregnant women with PIH and GDM experience higher stress levels than do non-pregnant women and healthy pregnant women. Further, our results indicate that sleep quality worsens during the third trimester compared with the second trimester.  相似文献

In this paper, I document trends in women's occupational mobility between 1980 and 2007 in the U.S labor market, and link these trends to two distinct sources: compositional and structural changes. In this context, compositional changes refers to the over time trends in the distributions of men and women in the occupational wage hierarchy, while structural changes are the trends in the relative standing of occupations in the wage hierarchy over time. The findings provide empirical evidence for both processes, indicating that the impressive upward occupational mobility of American women is a consequence not only of their increased access to highly paid occupations, but also of the higher wage increments in their typical occupational profiles relative to men's—a structural change not often acknowledged by sociologists.  相似文献
