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

Despite growing literature on Latino families and Latino queer identities, there has been relatively little empirical research on Latino same‐sex families. Likewise, emerging empirical research on gay and lesbian couples tends to focus on the experiences of middle‐class, well‐educated, White couples. I argue that combining theoretical and empirical works on sexuality, Chicano studies, and queer studies can assuage this lack of diversity in each body of literature. This work first examines current literature on Latino families, with a focus on Latino familism. This is followed by a brief examination of current literature on queer Chicanos. Lastly, it will discuss queer families and the lack of current literature on Latino same‐sex couples, in order to present a course of action for further research on the intersectional social location of queer Chicano families.  相似文献

The ratio bias—according to which individuals prefer to bet on probabilities expressed as a ratio of large numbers to normatively equivalent or superior probabilities expressed as a ratio of small numbers—has recently gained momentum, with researchers especially in health economics emphasizing the policy importance of the phenomenon. Although the bias has been replicated several times, some doubts remain about its economic significance. Our two experiments show that the bias disappears once order effects are excluded, and once salient and dominant incentives are provided. This holds true for both choice and valuation tasks. Also, adding context to the decision problem does not alter this finding. No ratio bias could be found in between-subject tests either, which leads us to the conclusion that the policy relevance of the phenomenon is doubtful at best.  相似文献

The aim of this article is to present an investigation of the action-representation relationship, via the processes which arise from the effects of one's action and the effects of one's capacity (normative and subjective). These effects are, in our view, of major importance, for they link social legitimation and the personal skill necessary for the preparation and carrying out of action. We look at this complex relationship, and propose a model, the capacity model, which situates action as an executory regulator of representation, which allows us to take some steps towards an explanation of the processes which link action and representation within the identity dynamic.  相似文献

The Swedish welfare state has, during the twentieth century, developed into the primary guarantor of health and social services as well as economic security. As the welfare state has developed, a new group of professions has emerged which can be described as welfare state professions. In this paper I will point out a few central aspects of how female‐dominated welfare state professions have emerged and developed within the framework of the Swedish welfare state's expansion. These ideas will then be demonstrated on two female‐dominated occupations, nurses and occupational therapists, which have developed in close association with the expansion of the welfare state. The results indicate that the emergence of a centrally planned welfare state and the occupational groups' organizational resources have been of crucial importance for the professional development of female‐dominated health and care occupations in Sweden. The welfare state has opened up new professional fields and created a stable labour market, which has provided good conditions for professional organizing. The state has also been quick to establish relationships with occupational groups whose professional competence has been deemed to be suited to the welfare political context. However, the state's interests in professional matters have often been in conflict with those of the professions themselves, regarding, for example, education, sub‐specialization and certification. One conclusion that can be drawn is that the Swedish welfare state has acted both as an engine and a brake regarding professional development and status.  相似文献

Three experiments investigated the role of prosodic structure for infants' recognition of embedded word sequences. Six‐month‐olds were familiarized with 2 versions of the same sequence, 1 corresponding to a well‐formed prosodic unit and the other to a prosodically ill‐formed sequence (although a successive word series). Next, infants heard 2 test passages. One included the well‐formed unit, and the other included the ill‐formed sequence. In Experiment 1, infants listened longer to the passage containing the well‐formed unit, suggesting that such units, even when they are embedded, are better recognized. Experiments 2 and 3 showed that this better recognition does not depend on an acoustic match between the familiarized sequences and their later embeddings. This suggests that the advantage of the well‐formed unit is at least partially due to infants' use of prosody to parse continuous speech.  相似文献
