A bibliographic study on a multidisciplinary subject, such as occupational stress, requires a multidatabase query facility. Given this, we searched eight databases belonging to different fields (medicine, psychology, etc.) and from different countries. Thus, more than 26000 references on occupational stress were gathered. A bibliographic corpus of this sort is unusable because of the heterogeneous format of the records and the number of duplicate entries. Considering the limitations of commercial programs, we have developed a system, called WebStress, for reformatting the data and removing duplicates. The huge number of references and the research needs of updating and searching have necessitated the addition of several other functions to WebStress. Therefore WebStress comprises a web interface that makes it possible to search the corpus with advanced features (using clustering, a specialized thesaurus on stress and Boolean queries). In addition to the usual bibliographic queries on a specific database such as Medline, WebStress provides bibliometric analysis of the corpus, which might contribute to a detailed analysis on occupational stress in order to highlight the networks of researchers and to find the main topics studied in this area. WebStress is not yet available to researchers in general. It is being further developed, and also permission needs to be obtained from the eight commercial bibliographic databases that it consults. 相似文献

In a public good environment with positively correlated types, we characterize optimal mechanisms when agents have private information and can enter collusive agreements. First, we prove a weak‐collusion‐proof principle according to which there is no restriction for the principal in offering weak‐collusion‐proof mechanisms. Second, with this principle, we characterize the set of allocations that satisfy individual and coalitional incentive constraints. The optimal weakly collusion‐proof mechanism calls for distortions away from first‐best efficiency obtained without collusion. Allowing collusion restores continuity between the correlated and the uncorrelated environments. When the correlation becomes almost perfect, first‐best efficiency is approached. Finally, the optimal collusion‐proof mechanism is strongly ratifiable. 相似文献

The health situation in Russia has often been characterized as a long‐running crisis. From the 1960s until the beginning of the 2000s, the declining life expectancy trend was substantially interrupted only twice: once in the mid‐1980s as a result of Gorbachev's anti‐alcohol campaign, and again at the end of the 1990s as a result of the “rebound” effect following the dramatic rise in mortality associated with the acute socioeconomic crisis. In both cases, the progress made proved to be short‐lived. A third mortality decline in Russia began in 2003 and is still ongoing. We investigate the components and driving forces of this new development, in particular the role played by cardiovascular diseases. Using cause‐specific mortality data, we identify the main features of the recent improvements and compare these features with those observed in selected European countries, specifically France, Poland, and Estonia. Our aim is to gauge whether the features of the improvements in these countries are similar to those of the recent advancements made in Russia. Although the recent improvements in Russia have features in common with initial stages of prior mortality declines in other countries and may support optimism about the future, a return to mortality stagnation cannot be ruled out. 相似文献

The objective of this research is to investigate gender difference and the burden of adversity during the life course of people who develop gambling problems. A sample of 86 adult participants met the criteria for at-risk problem gambling over the last 5 years. Data were obtained from informants during semi-structured face-to-face interviews, using SCID I and II, SOGS, Module K and a recount of life trajectories methodology. The results showed a high level of adversity throughout the life trajectories of the men and women studied. The results indicated that the major load of mental health disorders, the presence of anxiety disorders and co-morbid mental health disorders are more significant among women. Results also indicated a significant presence of violence in the lives of both men and women during early childhood and adolescence. During adulthood, women are more likely to be victims of intimate partner or marital violence whereas men tended to cumulate difficulties in social fields and especially in their professional lives. This significant burden of adversity creates a number of difficulties which makes it complicated to isolate gambling activities. Clinicians might have difficulty detecting female gamblers during consultation, especially when they present with co-morbid mental health disorders and violence issues. 相似文献

ABSTRACT The aim of this article is to examine senior women's involvement experience in Quebec, Canada. Study results are based on a qualitative methodology, and shed light on family history and continuity in the involvement trajectory, diversity in terms of group type and involvement practices, and gender differences in involvement. The meaning that older women attribute to their involvement is also addressed, including attitudes toward feminism. The discussion highlights the extent to which older women's involvement has been marked by their life trajectories, above and beyond their age. In sum, their involvement in the private and public spheres is quite impressive. 相似文献

We design a probability distribution for ordinal data by modeling the process generating data, which is assumed to rely only on order comparisons between categories. Contrariwise, most competitors often either forget the order information or add a non-existent distance information. The data generating process is assumed, from optimality arguments, to be a stochastic binary search algorithm in a sorted table. The resulting distribution is natively governed by two meaningful parameters (position and precision) and has very appealing properties: decrease around the mode, shape tuning from uniformity to a Dirac, identifiability. Moreover, it is easily estimated by an EM algorithm since the path in the stochastic binary search algorithm can be considered as missing values. Using then the classical latent class assumption, the previous univariate ordinal model is straightforwardly extended to model-based clustering for multivariate ordinal data. Parameters of this mixture model are estimated by an AECM algorithm. Both simulated and real data sets illustrate the great potential of this model by its ability to parsimoniously identify particularly relevant clusters which were unsuspected by some traditional competitors. 相似文献

We propose a model of monopolistic competition with additive preferences and variable marginal costs. Using the concept of “relative love for variety,” we provide a full characterization of the free‐entry equilibrium. When the relative love for variety increases with individual consumption, the market generates pro‐competitive effects. When it decreases, the market mimics anti‐competitive behavior. The constant elasticity of substitution is the only case in which all competitive effects are washed out. We also show that our results hold true when the economy involves several sectors, firms are heterogeneous, and preferences are given by the quadratic utility and the translog. 相似文献
