We study distributional properties of generalized order statistics (gos) related by a random shift or scaling scheme in the continuous and discrete case, respectively. In the continuous case, we obtain new characterizations of distributions relating non-neighbouring gos extending some results given in the literature for the neighbouring cases. On the other hand, in the discrete case, we investigate the existence and uniqueness of a discrete parent distribution supported on the integers whose gos are related by a random translation.  相似文献

We experimentally study punishment patterns across network structures, and their effect on cooperation. In a repeated public goods setting, subjects can only observe and punish their neighbors. Centralized structures (like the star network) outperform other incomplete networks and reach contribution levels like the ones observed in a complete network. Our results suggest that hierarchical network structures with a commonly observed player benefit more from sanctions not because central players punish more, but because they follow, and promote, different punishment patterns. While quasi-central players in other incomplete architectures (like the line network) retaliate, and get trapped in the vicious circle of antisocial punishment, central players in the star network do not punish back, increase their contributions when sanctioned by peripheral players, and sanction other participants in a prosocial manner. Our results illustrate recent field studies on the evolutionary prevalence of hierarchical networks. We document a network-based rationale for this positive effect in an identity-free, fully anonymous environment. (JEL C72, C91, C92, D90, H41)  相似文献

The aim of this research was to adapt and validate the Concern with Acting Prejudiced (CAP) scale for a Spanish sample. This measure evaluates concern about appearing prejudiced to others or oneself and the motivation not to deviate from personal egalitarian standards. First, we completed the translation and an item content validity analysis. Then, in Study 1 (N = 198), we conducted an exploratory factor analysis. In Study 2 (N = 383), we conducted a confirmatory analysis of the unifactorial structure of the Spanish version of the scale and examined its validity. In Study 3 (N = 89), we explored the moderating role of participants’ concern with acting prejudiced in the relation between implicit prejudice and explicit prejudice. The results confirmed the unifactorial structure of the scale, its appropriate psychometric properties and its predictive validity. Moreover, we confirmed that the CAP moderated the relation between implicit and explicit prejudice. In participants with a low concern with acting prejudiced, implicit prejudice was positively related with modern prejudice; in participants with a high concern with acting prejudiced, these variables were not related.  相似文献

The current study evaluated whether training intraverbal naming would be sufficient to establish visual-visual matching-to-sample (MTS) performances in college students. In the first experiment, we used a multiple-probe design across stimulus sets to assess whether six participants could match arbitrary visual stimuli (AB) after learning to tact their two experimentally defined classes (A’ and B’) and then intraverbally relate their names (i.e., “A’ goes with B’”). All participants matched the stimuli accurately after training, as well as emitted the trained intraverbals. In the second experiment, we used a multiple baseline design across four participants to assess whether the same training would produce bi-directional intraverbals in the form of “B’ goes with A’,” and MTS performance consistent with symmetry (BA). All participants responded accurately during matching and intraverbal tests. Across both experiments, participants stated the trained intraverbals while performing the matching task. Results showed that MTS performance can be established solely by verbal behavior training.  相似文献

This study tests the relationships between workaholism (i.e. working excessively and compulsively), sleep problems and cardiovascular risk in 537 employees from five Spanish hospitals. Four types of worker (i.e. workaholics, positive workers, compulsive workers and hard workers) were distinguished, and their health indicators were compared. The results showed that workaholics experienced significantly more sleep problems (i.e. morning tiredness, sleeping while driving and sleeping fewer hours both on weekdays and at weekends, with poorer quality), had higher relative risk scores, and consumed more caffeine and alcohol than the other patterns of worker (positive, compulsive and hard workers). Further analyses revealed that sleep problems fully mediated the relationship between workaholism (i.e. working excessively and compulsively) and cardiovascular risk. The study emphasizes the fact that being a workaholic might be a significant risk factor for having sleep problems and cardiovascular disease.  相似文献

Contemporary scientific analyses of public organizations underscore the salience of management for understanding how governmental bureaucracies perform. Yet little is known of administrators from minority social groups, and whether their organizations perform better or worse than other bureaucracies. Emphasizing the impact of network engagement on organizational performance, this exploratory study addresses this important research deficiency. A critical component of the analysis presented is the differential impact of administrative engagement with internal and external networks on minority and status quo clientele outcomes. The findings have important implications for studies of managerial networking, equity, and representation in public organizations.  相似文献

Utilizing current information to project prospective ill health prevalence can help prepare the country to ensure the well-being of older people. The prevalence of ill health in terms of physical, psychological, and cognitive health dimensions was estimated by age, sex, and education attainment level using the 2018 Longitudinal Study on Aging and Health in the Philippines. Subsequently, the said rates were integrated into population projection estimates from 2020 to 2080. It was observed that the depression prevalence rate among older people was highest at above 40%, while physical and cognitive limitations were at around 18% and 22% respectively. It was also found that prevalence rates of ill health increased with age and that ill health was more prevalent among women than men, particularly at more advanced ages. The use of population projections has shown that education differentials in the analyses estimate lower prevalence rates of ill health for both sexes. The findings provide estimates for the prospective care needs of the older population in the Philippines. It was also suggested that education may possibly have preventive effects on ill health. Utilizing present information in order to prepare for issues can be beneficial for securing the well-being of older adults.  相似文献

Community‐based organizations (CBOs) are now cast among the lead actors in welfare reform. But do they have adequate capacity to perform this critical leadership function? Early findings from fifteen state‐funded projects in Texas show that state planners must carefully assess the capacity of a CBO to initiate and sustain an innovation at the local level. The authors examine six organizational variables that predict success or failure: goals, management, technology, funding, community involvement, and performance.  相似文献
