In poker, detrimental decision-making as a result of losing control due to negative emotions is known as tilting. Previous evidence suggests that poker experience is related to better emotion regulation in dealing with poker losses, and possibly to reduced severity of tilting in the game. A correlational on-line study (N = 417) was conducted to operationalize the tilting phenomenon by defining certain experiential characteristics that conceivably protect players from tilting or predispose them to it. These characteristics, as well as a measurement of poker experience, were then used in predicting the severity of tilting. It was hypothesized that (1) players with more poker experience are more likely to perceive having tilted less severely, as a result of accumulating poker experience; (2) players with more poker experience have lower severity of tilting; (3) players with more poker experience report lower emotional sensitivity to losses; and (4) players with a higher emotional sensitivity to losses have higher severity of tilting. Hypotheses 1 and 4 were supported, hypothesis 3 was weakly supported, but contrary to hypothesis 2, poker experience was associated with higher tilting severity. It is argued that these results are sensible if experienced players are less likely to tilt in relative terms, per single hand, but more likely to tilt in the long run. 相似文献

Progression-free survival (PFS) is a frequently used endpoint in oncological clinical studies. In case of PFS, potential events are progression and death. Progressions are usually observed delayed as they can be diagnosed not before the next study visit. For this reason potential bias of treatment effect estimates for progression-free survival is a concern. In randomized trials and for relative treatment effects measures like hazard ratios, bias-correcting methods are not necessarily required or have been proposed before. However, less is known on cross-trial comparisons of absolute outcome measures like median survival times. This paper proposes a new method for correcting the assessment time bias of progression-free survival estimates to allow a fair cross-trial comparison of median PFS. Using median PFS for example, the presented method approximates the unknown posterior distribution by a Bayesian approach based on simulations. It is shown that the proposed method leads to a substantial reduction of bias as compared to estimates derived from maximum likelihood or Kaplan–Meier estimates. Bias could be reduced by more than 90% over a broad range of considered situations differing in assessment times and underlying distributions. By coverage probabilities of at least 94% based on the credibility interval of the posterior distribution the resulting parameters hold common confidence levels. In summary, the proposed approach is shown to be useful for a cross-trial comparison of median PFS. 相似文献

The literature on the health-promoting effects of community work has primarily dealt with the population in retirement age, yet the vast majority of volunteers are people still in the workforce. The aim of this study is to observe the relationship between volunteering and health within the context of working life, considering paid work conditions and motives to volunteer as moderating variables. We conducted an online survey with a sample of Swiss workers employed in different industries. Results show that volunteers with self-determined motives (but not with controlled motives) report lower levels of stress and burnout than non-volunteers. Moreover, volunteers in general (regardless of the quality of motivation) report higher levels of work engagement and well-being. Analyses further reveal an interaction effect for burnout and stress, where the difference between self-determined volunteers and non-volunteers becomes larger with unfavorable working conditions at their paid job, hinting at potential compensatory effects. Implications for future research and the voluntary sector are discussed. 相似文献

This article employs empirical analysis on working life coaching in order to offer a complimentary perspective on debates concerning individualization and class. Instead of viewing individualization as a process which erodes or radically shapes structures of class, this article interrogates individualization as a process which individualizes the relation between capital and labour in such a way that it appears in an individualized form. Examining practices of working life coaching sheds light on the ways in which the antagonism of capital and labour is experienced, articulated in an individual form and offered solutions for, and also on the ways in which such practices actually silence and cement the antagonism they are supposed to solve. 相似文献

ABSTRACTAmin’s Leninist-Maoist vision is unlikely to be persuasive to twenty-first century citizens. Nonetheless, there is a rational kernel in Amin’s call for a new worldwide political organization. Some structures, mechanisms and tendencies of the capitalist world economy are relatively enduring and some patterns recurrent, although the world economy is also fluid, constantly changing and evolving. Although waves of globalization have radically transformed human societies and their economic activities during the past 500 years also in many positive ways, the expansion of the international society and world economy has often been characterized by violence, imperial subjection and colonial expropriation and exclusion. There is a rational kernel also within Amin’s analysis of the current world-political situation. Command over space and time by investors and megacorporations is power. Emancipation aims at freedom from domination. The decline of the World Social Forum indicates that progressive politics must move ‘beyond the concept of a discussion forum’. My argument is that emancipation from unnecessary, unneeded and unwanted sources of determination requires global transformative agency and planetary visions about alternatives. 相似文献

Some nonprofits evolve from small into large international organizations. For years, “structure follows strategy” (Chandler) has been the dictum to explain organizational strategic changes like the ones in nonprofits. But scholars also recognized organization structure to be a precondition to carry out certain strategies. Nevertheless, research on structure and strategy in nonprofits is limited. This paper explores the mutual influence of organization structure and strategy in high-performing nonprofits in Iberoamerica based on a secondary analysis of 20 unpublished research cases of the Social Enterprise Knowledge Network. It follows the research question: Which organizations’ strategies and structures characterize high-performing nonprofits over time? Four types of organizing patterns emerged: starting-up, professionalizing, decentralizing, and conglomerating. 相似文献

We used a regional sample of children in long‐term foster care to investigate the prevalence of placement breakdown in adolescence, and to assess risk factors/risk markers for placement disruption. The sample consisted of all 136 foster children in the region, born 1980–1992, who on their 12th birthday had been in the same foster family for at least 4 years. They were followed in case files until date of disruption or their 18th birthday. Data on conditions before and during placement were retrieved from case files, and analysed in bi‐ and multivariate models. Results showed that one in four placements broke down in adolescence. The median child who experienced a breakdown was 14 years old, and had been in the same foster home for more than 10 years. Prominent risk factors were (i) being placed after age 2 and (ii) having a birth sibling in the same foster home. We also uncovered strong risk markers that can be viewed as precursors of placement disruption. When the child or the foster parents repeatedly over time expressed dissatisfaction with the placement, this ended with a placement breakdown in 60% of cases. Implications for practice are discussed. 相似文献
