A model for the assessment of exposure to Listeria monocytogenes from cold-smoked salmon consumption in France was presented in the first of this pair of articles (Pouillot et al ., 2007, Risk Analysis, 27:683–700). In the present study, the exposure model output was combined with an internationally accepted hazard characterization model, adapted to the French situation, to assess the risk of invasive listeriosis from cold-smoked salmon consumption in France in a second-order Monte Carlo simulation framework. The annual number of cases of invasive listeriosis due to cold-smoked salmon consumption in France is estimated to be 307, with a very large credible interval ([10; 12,453]), reflecting data uncertainty. This uncertainty is mainly associated with the dose-response model. Despite the significant uncertainty associated with the predictions, this model provides a scientific base for risk managers and food business operators to manage the risk linked to cold-smoked salmon contaminated with L. monocytogenes. Under the modeling assumptions, risk would be efficiently reduced through a decrease in the prevalence of L. monocytogenes or better control of the last steps of the cold chain (shorter and/or colder storage during the consumer step), whereas reduction of the initial contamination levels of the contaminated products and improvement in the first steps of the cold chain do not seem to be promising strategies. An attempt to apply the recent risk-based concept of FSO (food safety objective) on this example underlines the ambiguity in practical implementation of the risk management metrics and the need for further elaboration on these concepts. 相似文献

Recent studies on transnational mothering have explored the various strategies migrant women use to negotiate their absence from home; however, there is limited knowledge on how migration status diversifies transnational mothering practices. To fill this gap, I conducted in‐depth interviews and observations of Filipino migrant mothers working in the domestic service sector in and around Paris. The consequences of migration include the prolongation of a planned stay in France, emotional difficulties due to family separation, and distant mother–child relationships. Transnational family life appears more complicated and difficult to manage for undocumented migrant mothers since they cannot easily visit their family back home, which they try to compensate by resorting to more intense transnational communication and gift‐giving practices. Hence, migration status plays an important role in shaping transnational motherhood. 相似文献

桐城派在二百余年传衍发展过程中,书院讲学起到了基因性塑造作用,而徽州紫阳书院、问政书院和安庆敬敷书院等,则是桐城派在安徽从事书院教育的主要基地.两地人才的培养、文风的培育、相互间文化交流的增多,与刘大槐、姚鼐等多年主讲这几座书院有密切关系.对此进行系统梳理和深入研究,可以帮助我们更好地理解桐城派的传承规律和清代安徽书院教育的基本风貌. 相似文献

This paper analyzes the “gender strategies” of a sample of Israeli women social workers as evidenced in the recommendations that they write for the courts on custody and visiting rights for divorcing couples. Textual analysis of these reports reveals what Hochchild terms a “traditional gender strategy,” manifested in a consistent pattern of gender stereotyping. There are clear differences in the way the social workers present the husband and wife as persons, both separately and in relation to one another, and in the roles that they expect them to fulfill, with the man being assigned the provider role and the woman the parent role. Even the way they collect information about the two parents' relationships with their children is different. The paper concludes with a discussion of the practical implications of the findings. 相似文献

Stakeholders making decisions in public health and world trade need improved estimations of the burden‐of‐illness of foodborne infectious diseases. In this article, we propose a Bayesian meta‐analysis or more precisely a Bayesian evidence synthesis to assess the burden‐of‐illness of campylobacteriosis in France. Using this case study, we investigate campylobacteriosis prevalence, as well as the probabilities of different events that guide the disease pathway, by (i) employing a Bayesian approach on French and foreign human studies (from active surveillance systems, laboratory surveys, physician surveys, epidemiological surveys, and so on) through the chain of events that occur during an episode of illness and (ii) including expert knowledge about this chain of events. We split the target population using an exhaustive and exclusive partition based on health status and the level of disease investigation. We assume an approximate multinomial model over this population partition. Thereby, each observed data set related to the partition brings information on the parameters of the multinomial model, improving burden‐of‐illness parameter estimates that can be deduced from the parameters of the basic multinomial model. This multinomial model serves as a core model to perform a Bayesian evidence synthesis. Expert knowledge is introduced by way of pseudo‐data. The result is a global estimation of the burden‐of‐illness parameters with their accompanying uncertainty. 相似文献

拜伦的叙事诗作品,尤其是其代表作<唐璜>,显示出诗人极强的叙事节奏感.无论是叙事主线的跌宕起伏,还是叙事辅线--各类非叙述性插入文本的错落有致,抑或是诗歌文本中场景与停顿等技巧的穿插运用,都可见出拜伦对叙事节奏的驾驭能力.拜伦这一能力的发挥与其对时间的敏感与重视息息相关,作为诗人的经验和智慧告诉他:时间为诗歌叙事提供了素材;佳作不仅是应时的产物,同时也能经得起时间的考验. 相似文献

This paper considers five test statistics for comparing the recovery of a rapid growth‐based enumeration test with respect to the compendial microbiological method using a specific nonserial dilution experiment. The finite sample distributions of these test statistics are unknown, because they are functions of correlated count data. A simulation study is conducted to investigate the type I and type II error rates. For a balanced experimental design, the likelihood ratio test and the main effects analysis of variance (ANOVA) test for microbiological methods demonstrated nominal values for the type I error rate and provided the highest power compared with a test on weighted averages and two other ANOVA tests. The likelihood ratio test is preferred because it can also be used for unbalanced designs. It is demonstrated that an increase in power can only be achieved by an increase in the spiked number of organisms used in the experiment. The power is surprisingly not affected by the number of dilutions or the number of test samples. A real case study is provided to illustrate the theory. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献
