Earlier research has established that the full potential of microcomputers is not being achieved by production management in small companies. Moreover, questionnaire results and in-company interviews were used to support suggested reasons for this situation. This paper reports further work carried out to examine the issues raised in far more detail. Collaboration took place with nine separate companies over a range of applications. Three of these case studies are presented in detail, and general conclusions drawn relating both to these specific studies and to the total collaboration.  相似文献

The main aims of this two-wave prospective study were to (1) present different theoretical mechanisms for relationships between bullying and personality characteristics, (2) determine forward and reverse long-term associations between victimization from bullying and personality traits included in the five-factor model and (3) establish whether these personality traits contribute to the variance in bullying, beyond work environment factors in the form of role conflict and role ambiguity. The prospective sample comprised 3066 Norwegian employees. The time lag between the two measurement points was two years. Neuroticism significantly predicted subsequent bullying in analyses of direct associations between personality traits and victimization. When adjusting for role conflict and role ambiguity, conscientiousness emerged as the only significant predictor of later victimization from bullying. In tests of reverse associations, victimization from bullying at baseline was significantly related to agreeableness, conscientiousness and openness at follow-up. Taken together, the study findings indicate that personality traits may function as both predictors and outcomes of workplace bullying.  相似文献

There is a dearth of knowledge in the coping literature on how minoritized youth cope with racism-related stressors and the predictors of effective coping responses. This two-wave study examined the direct and indirect effects of ethnic-racial socialization on depressive and anxiety symptoms via proactive coping with discrimination in a community sample of 135 Latinx adolescents (Mage = 16, SD = 1.27; 59% female). Results indicate that cultural socialization was related to higher use of proactive coping with discrimination 6 months later, which in turn, was related to fewer depressive and anxiety symptoms. There were no direct or indirect effects between preparation for bias and mental health outcomes.  相似文献

We analyze data from the South African Stress and Health Study, a nationally representative in-person psychiatric epidemiologic survey of 4,351 adults conducted as part of the World Mental Health Survey Initiative between January 2002 and June 2004. All blacks (Africans, Coloreds, and Indians) initially report higher levels of non-specific distress and anger/hostility than whites. Access to socioeconomic resources helps explain differences in non-specific distress between Coloreds and whites and Indians and whites. However, only when social stressors are considered do we find few differences in psychological distress (i.e., non-specific distress and anger/hostility) between Africans and whites. In addition, self-esteem and mastery have independent effects on non-specific distress and anger/hostility, but differences between Coloreds and whites in feelings of anger/hostility are not completely explained by self-esteem and mastery. The findings contribute to the international body of work on social stress theory, challenge underlying assumptions of the minority status perspective, and raise a series of questions regarding mental health disparities among South Africans.  相似文献

Objective. Students of political behavior have often found that the primary use of languages other than English impedes many forms of political participation in the United States. We develop expectations about how language choice operates with social context to influence an individual's decision to vote. Although choosing to speak a language other than English—in this case, Spanish—may affect the amount of political information individuals have at their disposal, this choice also represents their access to social and community resources that enable, rather than impede, political participation. Methods. We examine the voting behavior of Latinos, almost entirely Mexican Americans, living in south Texas counties on the U.S. border and reconsider the consequences of language choice for political behavior. Results. Controlling for past residential tenure, we find that Spanish‐speaking Latinos will be more likely to vote than English‐speaking Latinos. Conclusions. The establishment of ties to an ethnic group in a majority‐minority context over time mitigates the negative relationship between the use of Spanish as a primary language and voting.  相似文献

Networks of constellations of longitudinal observational databases, often electronic medical records or transactional insurance claims or both, are increasingly being used for studying the effects of medicinal products in real‐world use. Such databases are frequently configured as distributed networks. That is, patient‐level data are kept behind firewalls and not communicated outside of the data vendor other than in aggregate form. Instead, data are standardized across the network, and queries of the network are executed locally by data partners, and summary results provided to a central research partner(s) for amalgamation, aggregation, and summarization. Such networks can be huge covering years of data on upwards of 100 million patients. Examples of such networks include the FDA Sentinel Network, ASPEN, CNODES, and EU‐ADR. As this is a new emerging field, we note in this paper the conceptual similarities and differences between the analysis of distributed networks and the now well‐established field of meta‐analysis of randomized clinical trials (RCTs). We recommend, wherever appropriate, to apply learnings from meta‐analysis to help guide the development of distributed network analyses of longitudinal observational databases.  相似文献

This paper explores practice examples relating to young people's transitions from care to adulthood. It discusses examples drawn from young people's pathways to adulthood, leaving care law and policy and participation. The paper concludes with a discussion of the research evidence on promoting the resilience of young people from care to adulthood, by proposing a framework for evaluating the impact of practice. It is suggested that practice should be interrogated in respect of the contribution made to stability and continuity, educational achievement, involving young people, preparation and support into adulthood, and health and well‐being.  相似文献

Second-order stochastic dominance is used to determine preferences among various investments for any risk-averse decision maker. On the other hand, when faced with choosing between different insurance policies or disaster plans, a risk-averse decision maker should use a type of stochastic dominance called variability ordering. In this situation, second-order stochastic dominance has been used in previous research and is incorrect.  相似文献
