The present research examined whether the emotions of others (i.e., disappointment versus happiness with respect to a received outcome) influence own self-esteem when being overpaid. Results from two experiments demonstrated that participants reported higher performance self-esteem when the other expressed happiness rather than disappointment. This effect was only found in the condition where one was overpaid relative to the condition where one did not yet know one’s own outcome. In the second experimental study we further found that this interaction between the emotion of the other and the distribution situation only emerged among participants low (relative to high) in personal need for structure. Implications with respect to the relationship between overpayment and self-esteem and the interpersonal effects of emotions in this process are discussed. 相似文献

A significant proportion (4%, Australian Institute of Health and Welfare, 2008) of children and young people in Australia live in some form of residential care, usually in small group‐homes staffed by residential care workers in shifts. However, as Hawkins‐Rodgers (2007) points out, these placements are often not resourced to heal the effects of trauma and multiple attachment disruptions in their residents. The lack of an archetypal ‘family’ has led in the past to family therapists considering that there is little work to be done with such clients. This leaves such placements to be supported most frequently by clinicians who specialise in behaviour management and other linearly founded models of practice. The Alternate Care Clinic (ACC) is the first mental health service in New South Wales dedicated entirely to children and young people in out of home care with a high level of complex needs. This article examines the systemic therapeutic model the clinic has developed in the last two years. In particular, the article seeks to explore the importance of ‘meaning making’ in a diffuse parental system, particularly with regards to the term ‘family’. The complexities of working in this area and possible ways forward are illustrated with a closely worked case study. 相似文献

This paper explores the antecedents, experiences and consequences of marginalization as reported and dealt with by disabled Iranian immigrants in Belgium. This work extends the work of Gallie and colleagues and Siegrist demonstrating that the forces of marginalization applicable to all immigrants are particularly pertinent to disabled immigrants. The research is based on 26 in‐depth, face‐to‐face interviews, focus groups, interviews with government officials and immigration experts, ethnographic work and official government statistics. The findings detail how the combined forces of history, context and reasons for immigration; isolation, vulnerability and perceived loss of control; religion and rejection; lack of reciprocity in social exchanges; problems in obtaining jobs; and difficulties in negotiating an entry into Belgian society combine to sustain marginizalation. As a consequence, disabled immigrants in this group are generally excluded from society and discriminated against in terms of citizenship, education, jobs and general acceptance. 相似文献

The effects of different sales strategies on consumer product evaluation were investigated. It was expected that direct product experience could decrease economic product valuation. Experiments 1 and 2 studied the effects of product trials and money-back guarantees on consumer willingness to pay (WTP). It appeared that WTP was significantly lower after a product trial than with a money-back guarantee or normal sale. In Experiment 3 a structural equation model showed that product trials had a positive effect on attitude toward the product. Also, a negative effect on WTP was found when the effect was measured directly, but a positive effect when the effect was measured indirectly (through attitude). 相似文献

Compared to other countries that have suffered from the Nazioccupation, the destructive impact of the Holocaust on theJewish population has been particularly strong in the Netherlands. This paper gives a demographicreconstruction of the Jewish population in the Netherlands by the end of the war (1945),disaggregated by age and sex. The reconstruction is based on two approaches: a forwardprojection 1941–1945, starting from registration data supplemented by information onHolocaust losses; and a backward projection 1966–1945, starting from an enumerationof Halachic Jews carried out in 1966. The two approaches yieldtwo estimates that are comfortingly similar. 相似文献

Soil nutrient mining and other forms of soil degradation threaten future soil productivity, especially in sub-Saharan Africa (SSA). Data from 36 countries in SSA show a significant relationship at the supra-national level between soil nutrient depletion (including erosion), reduced fallow periods, and population pressure and thus illustrate the unsustainable population-agriculture-environment nexus on the continent which so far has been described in case studies only. It appears that Malthusian mechanisms are at work, despite encouraging indications of farmers' concerns and adaptation to changing conditions. It is agreed that a re-examination of the common land degradation assessments and farmers' response to changing conditions would be useful, however, this should not delay other recommended interventions. 相似文献

Both treatment efficacy and safety are typically the primary endpoints in Phase II, and even in some Phase III, clinical trials. Efficacy is frequently measured by time to response, death, or some other milestone event and thus is a continuous, possibly censored, outcome. Safety, however, is frequently measured on a discrete scale; in Eastern Cooperative Oncology Group clinical trial E2290, it was measured as the number of weekly rounds of chemotherapy that were tolerable to colorectal cancer patients. For the joint analysis of efficacy and safety, we propose a non-parametric, computationally simple estimator for the bivariate survival function when one time-to-event is continuous, one is discrete, and both are subject to right-censoring. The bivariate censoring times may depend on each other, but they are assumed to be independent of both event times. We derive a closed-form covariance estimator for the survivor function which allows for inference to be based on any of several possible statistics of interest. In addition, we derive its covariance with respect to calendar time of analysis, allowing for its use in sequential studies. 相似文献

We investigate the effect of unobserved heterogeneity in the context of the linear transformation model for censored survival
data in the clinical trials setting. The unobserved heterogeneity is represented by a frailty term, with unknown distribution,
in the linear transformation model. The bias of the estimate under the assumption of no unobserved heterogeneity when it truly
is present is obtained. We also derive the asymptotic relative efficiency of the estimate of treatment effect under the incorrect
assumption of no unobserved heterogeneity. Additionally we investigate the loss of power for clinical trials that are designed
assuming the model without frailty when, in fact, the model with frailty is true. Numerical studies under a proportional odds
model show that the loss of efficiency and the loss of power can be substantial when the heterogeneity, as embodied by a frailty,
is ignored.
