A quantitative assessment of the exposure to Listeria monocytogenes from cold-smoked salmon (CSS) consumption in France is developed. The general framework is a second-order (or two-dimensional) Monte Carlo simulation, which characterizes the uncertainty and variability of the exposure estimate. The model takes into account the competitive bacterial growth between L. monocytogenes and the background competitive flora from the end of the production line to the consumer phase. An original algorithm is proposed to integrate this growth in conditions of varying temperature. As part of a more general project led by the French Food Safety Agency (Afssa), specific data were acquired and modeled for this quantitative exposure assessment model, particularly time-temperature profiles, prevalence data, and contamination-level data. The sensitivity analysis points out the main influence of the mean temperature in household refrigerators and the prevalence of contaminated CSS on the exposure level. The outputs of this model can be used as inputs for further risk assessment. 相似文献

This article examines the subjective antecedents of life satisfaction of workers. Adopting a ‘bottom-up’ perspective, we assessed the unique influence that satisfaction with multiple life domains have on evaluative judgments of overall life satisfaction. Based on a nationwide sample of 530 Chilean workers, we simultaneously tested the effects of seven life domain satisfactions that have been consistently included in extant models of life satisfaction and subjective well-being. These were satisfaction with health, financial situation, social relationships, one’s self-worth, leisure-time, family, and work. Having controlled for age and gender, results showed that satisfaction with one’s financial situation was the dominant predictor of overall life satisfaction of workers, with a weight of .36. Satisfaction with family, work, and health had effects of .25, .14, and .14, respectively. Interestingly, satisfaction with one’s self-worth, leisure-time, and social relationships did not have statistically significant effects on life satisfaction, although the first two showed t values near the critical value. 相似文献

This paper examines a possibility of enlarging the domain of definition of individual preferences suggested by the recent literature on freedom of choice. More specifically, the possibility for an individual to have preferences that depend upon both the opportunity set that she faces and the particular alternative that she chooses from that set is considered. Even more specifically, the possibility for these preferences to value freedom of choice, as defined by the set theoretic relation of inclusion, while being consistent, in a certain sense, with the existence of a preference ordering over the options contained in opportunity sets is investigated. It is shown in the paper that a necessary condition for the existence of any transitive extended preferences of this type is for freedom of choice to be given no intrinsic importance.

Recent criticisms have led some to dismiss time-series analyses in the debate over the minimum wage. We investigate previous time-series studies showing that raising the minimum wage has a smaller impact on females than males. We reanalyze the data in light of recent developments in time-series methods and find that the minimum wage has a similar significant negative impact on both males and females. We conclude that, following a 10 percent increase in the minimum wage, both male and female employment drops from between 2 and 4 percent over a two-year period. This employment decrease slowly erodes as economic growth and inflation cause the minimum wage to fall below the market-clearing wage. We thank David Card and Alan Krueger for generously providing the data. 相似文献

The objectives of this study were to describe the different modalities of physical activity programs designed for moderate to severe dementia and to identify their impact on functional independence in activities of daily living (ADL). A critical review of randomized controlled trials related to the impact of physical activity programs in moderately to severely demented persons on ADL performance and meta-analysis of the identified studies were performed. Among the 303 identified articles, five responded to the selection criteria. Four out of the five studies demonstrated limited methodological quality. In one high-quality study, physical activity programs significantly delayed deterioration of ADL performance. The program components and ADL assessment tools vary widely across studies. Although the proposed treatments have not proven their efficiency in improving the ADL status of the patients, they were able to limit the decline in ADL functioning. Future research is warranted in order to identify clinically relevant modalities for physical activity programs for people with moderate to severe dementia. 相似文献

It has been reported that familiarity or incidental similarities with a stranger influenced an individual’s behavior. However, the effect of the sense of geographical proximity believing that someone comes from the same area that somebody has never been examined. Three field experiments examined this effect on donations to humanitarian organizations. In the first study, participants were asked by a confederate to donate food products to a humanitarian organization. In Study 2, participants were asked by confederates to donate money for children. In Study 3, donation boxes were displayed in bakeries with a message that invited customers to donate money for children. In all the studies, participants were led to believe that they would be helping people in need or people who live in their national or local geographic area. Results showed that donations were higher in the geographical proximity condition. This “neighborhood effect” was discussed. 相似文献

Although studies show that women who have sex with women (WSW) have poorer sexual health and more limited access to health care for gynecological problems than other women, the social processes giving rise to such health differences have not, so far, been explored. These processes may be formed in response to a dominant social norm, which assigns women to a heterosexual and monogamous sexuality. Based on data from a national random survey of sexuality (N = 6,824), enriched by qualitative interviews with WSW (n = 40), this analysis shows that bisexually active women had similar socio-demographic profiles to heterosexually active women, whereas homosexually active women appeared to be more highly educated than other women and less likely to live as couples than bisexually active women. Bisexually active women had more diversified sexual trajectories and sexual networks than other women. Chlamydia prevalence was found to be higher among bisexually active women, and homosexually active women reported fewer medical consultations for gynecological reasons. These analyses highlight the need to deconstruct the binary classification of homosexual versus heterosexual women. Because of constraint by the monogamous heterosexual norm, bisexually active women were less likely to be tested for sexually transmitted infections, and homosexually active women were less likely to have had gynecological follow-ups. 相似文献
