Abstract

This paper describes a micro-analysis of the cognitive appraisal of daily stressful events in a sample of correctional officers (COs). More specifically, the authors examined whether three attribution dimensions mediated the relationship between the occurrence of stressful events and the ‘significance’ of these events, and whether the latter functioned as a mediator between the attribution dimensions on the one hand and negative affect (outcome variable) on the other. Convincing indications were found for the mediating role of the ‘significance’ of a stressful event, while weak indications were found for the mediating role of the attribution dimensions. Finally, the strengths and weaknesses of daily event-recording methods are discussed at length.  相似文献

The transition from economic stagnation to sustained growth is often modeled thanks to “population‐induced” productivity improvements, which are assumed rather than derived from primary assumptions. In this paper the effect of population on productivity is derived from optimal behavior. More precisely, both the number and location of education facilities are chosen optimally by municipalities. Individuals determine their education investment depending on the distance to the nearest school, and also on technical progress and longevity. In this setting, higher population density enables the set‐up costs of additional schools to be covered, opening the possibility to reach higher educational levels. Using counterfactual experiments we find that one‐third of the rise in literacy can be directly attributed to the effect of density, and one‐sixth is linked to higher longevity. Moreover, the effect of population density in the model is consistent with the available evidence for England, where it is shown that schools were established at a high rate over the period 1540–1620.

We study the optimal design of mechanisms for the private provision of public goods in a setting in which donors compete for a prize of commonly known value. We discuss equilibrium bidding in mechanisms that promote both conditional cooperation and competition (i.e., the lottery and the all‐pay auction with the lowest‐bid payment rule) and rank their fund‐raising performance vis‐à‐vis their standard (pay‐your‐own‐bid) counterparts. The theoretically optimal mechanism in this model is the lowest‐price all‐pay auction—an auction in which the highest bidder wins the prize and all bidders pay the lowest bid. The highest amount for the public good is generated in the unique, symmetric, mixed‐strategy equilibrium of this auction. In the laboratory, the theoretically optimal mechanism generates the highest level of donations with three bidders but not with two bidders. (JEL D44, D64)  相似文献

Discrete lifetime data are very common in engineering and medical researches. In many cases the lifetime is censored at a random or predetermined time and we do not know the complete survival time. There are many situations that the lifetime variable could be dependent on the time of censoring. In this paper we propose the dependent right censoring scheme in discrete setup when the lifetime and censoring variables have a bivariate geometric distribution. We obtain the maximum likelihood estimators of the unknown parameters with their risks in closed forms. The Bayes estimators as well as the constrained Bayes estimates of the unknown parameters under the squared error loss function are also obtained. We considered an extension to the case where covariates are present along with the data. Finally we provided a simulation study and an illustrative example with a real data.  相似文献

Social work research and practice that address environmental sustainability have already become prominent. However, a change in unsustainable economic structures is also urgently needed. This study explored emerging opportunities in theory and practice for a sustainable economy that are relevant to the aims of social work. As practical examples, our study concerns ‘ecosocial innovations’, i.e., social innovations that combine ecological and social goals. We analysed how these grassroots innovations in the field of social work reflect crucial shared conceptions of alternative economies. The qualitative data set comprised of 50 ecosocial innovations and six case studies in five European countries. The findings show a rich diversity of ecosocial innovations and describe how they reframe economic purposes, value economic diversity and democratise the economy. We suggest that social work might consider these practices as opportunities for collaboration, especially regarding work with people on the margins of the labour market.  相似文献

To assess HIV disclosure discussions and related sexual behaviors among men who have sex with men (MSM) who meet sex partners online, 28 qualitative interviews with Seattle-area MSM were analyzed using grounded theory methods and themes and behavior patterns were identified. MSM found a greater ease in communicating and could prescreen partners through the Internet. However, no consistent relationship was found between HIV disclosure and subsequent behaviors: some were safer based on disclosure while perceived HIV status led others to risky behaviors. Interventions need to promote accurate disclosure while acknowledging its limitations and the need for men to self-protect.  相似文献

Peeters J. A comment on ‘Climate change: Social workers’ roles and contributions to policy debates and interventions' In this commenting article, I present several critical remarks about Lena Dominelli's contribution to the issue of climate change and its implications for social work. 1 In my view, her article lacks three important considerations. First, I argue that the issue of climate change should be addressed as part of a broader, fundamental challenge: the transition of the growth‐based economic system upon which our society is built. Second, within a context of social and ecological injustice, dealing with climate change inevitably requires a dimension of social struggle. Third and lastly, I emphasise social work's role in challenging the social, political and economic structures and processes that bring about climate change.  相似文献

Unemployment is the most basic risk covered by social security. Sickness, accident, maternity, incapacity, old age or even death can be considered as special cases of interruption of earnings. Unemployment is the standard case, where a worker loses earnings simply because he or she is unable to find gainful employment, without reference to any particular causality. Nevertheless, the unemployment branch is very often treated rather poorly, in comparison with other branches of social security. In most countries – except the United Kingdom – it was created much later than other branches, and it involves a larger part of assistance, as opposed to insurance. Usually, fewer people are covered against the risk, the conditions for entitlement are stricter, the benefits tend to be lower and shorter in duration, and controls and sanctions are more severe.1 People are generally worse off when their loss of earnings is the result of a dismissal rather than disease or accident. In this contribution we try to analyse the reasons why unemployment has such a relatively poor status in social security. And we examine the extent to which this difference of treatment can be considered a form of discrimination and, in some cases, contrary to the basic principles of international social law.  相似文献
