The Monte Carlo (MC) simulation approach is traditionally used in food safety risk assessment to study quantitative microbial risk assessment (QMRA) models. When experimental data are available, performing Bayesian inference is a good alternative approach that allows backward calculation in a stochastic QMRA model to update the experts’ knowledge about the microbial dynamics of a given food‐borne pathogen. In this article, we propose a complex example where Bayesian inference is applied to a high‐dimensional second‐order QMRA model. The case study is a farm‐to‐fork QMRA model considering genetic diversity of Bacillus cereus in a cooked, pasteurized, and chilled courgette purée. Experimental data are Bacillus cereus concentrations measured in packages of courgette purées stored at different time‐temperature profiles after pasteurization. To perform a Bayesian inference, we first built an augmented Bayesian network by linking a second‐order QMRA model to the available contamination data. We then ran a Markov chain Monte Carlo (MCMC) algorithm to update all the unknown concentrations and unknown quantities of the augmented model. About 25% of the prior beliefs are strongly updated, leading to a reduction in uncertainty. Some updates interestingly question the QMRA model. 相似文献

James Gillray represented the horrid barbarities of the French revolutionaries in his famous political satires which dramatised the event and showed Louis XVI as a martyr. He made the public aware of the dangers of the French Revolution and transfered the bloody massacres in a British context for the purpose of propaganda, warning his fellow countrymen against the disorder, violence and anarchy which could spread over to Britain. James Gillray took a conservative stance and his hand-coloured etchings alluded to the harmful effects of the French Revolution which threatened British stability, the Monarchy and the Constitution. 相似文献

This paper uses recent longitudinal data collected within the Migration between Africa and Europe (MAFE) project to investigate gender differences in the role of migrant networks in international mobility. Furthermore, we compare Congolese and Senegalese migration streams to examine how the interplay between gender and networks varies across contexts of origin. We go beyond previous studies by considering the case of spousal reunification alongside other forms of migration: we separate the role of the migrant spouse from other network ties, as failing to do so overestimates the role of migrant networks in female mobility. We further find that Senegalese women are more likely than men to rely on geographically concentrated networks, composed of close kin and established abroad for a long time. Gender differences are much less pronounced in the Congolese case, which we relate to the more rigid patriarchal norms in Senegal, restricting female autonomy both in terms of mobility and economic activity. 相似文献

Research in child development suggests that parents' emotional competence and emotion socialization practices are related to children's emotional functioning, including child internalizing difficulties. This research has not yet been translated into intervention or prevention programs targeting parents of older children and adolescents. The current study examined the efficacy of the Tuning in to Teens parenting program in improving emotion socialization practices in parents of preadolescents and reducing youth internalizing difficulties. Schools were randomized into intervention and control conditions. Data were collected from 225 parents and 224 youth during the young person's final year of elementary school (sixth grade) and again 10 months later in their first year of secondary school (seventh grade). Multilevel analyses showed significant improvements in parental emotion socialization and reductions in youth internalizing difficulties for the intervention condition. This study provides support for the efficacy of the TINT parenting program with a community sample. 相似文献

This literature review was conducted to identify obstacles in the provision of quality nursing care to people with disabilities within acute care settings. Research in 2006 by the Disability Rights Commission found that people with disabilities have healthcare needs that are not being adequately met with the quality of care expected or anticipated. Obstacles to the provision of high-quality nursing care are a matter of concern to nursing clinicians, educators and researchers involved with establishing and maintaining professional standards of care for nursing practice. Therefore, this review has identified three major themes illustrating barriers to provision of high-quality nursing care in the acute care setting to people with disabilities. Themes identified were: professional competence, professional attitudes and organisational management. Nurses have an obligation to take into account the concerns and needs of individual clients with a disability. 相似文献

This article is concerned with an empirical study of girls of the street in Mauritania. This study is original for three main reasons. First, it investigates Mauritania, a country where there have been very few studies of the phenomenon of children of the street. Secondly, it seems to us that though the academic literature on street children sometimes provides comparisons between girls and boys, very few studies focus specifically on girls of the street. Thirdly, the literature focusing on children of the street generally elucidates the mechanisms that lead some young people to live on the streets. On the contrary to previous literature, our study does not directly focus on mechanisms that lead some young people to live on the streets. Our study focuses on the question of the socio-economic determinants of the risk of violence. In other words, whereas the literature, following the hypothesis of aberrant families, uses violence as an explanatory factor for the phenomenon of children of the street, we attempt here to highlight the explanatory factors for the risk of violence and we treat this risk as an explained variable. A novel finding emerges from this study: there is less risk of violence facing girls of the street if the mother does not work. Conversely, the risk of violence is greater if the mother works and the father stays at home. 相似文献

As dual‐earner families have become the norm, the different kinds of ‘time’ children spend with parents has become an important issue. We use the 2000 Time Use Survey to identify adolescent children spending time alone at home, and interviews with 50 children aged 14 and 15 to explore young people's experiences. We investigate their views on their situations, appropriate domestic responsibilities and how they manage their time. We suggest that simple parental presence or absence is not necessarily the main issue for children. However, parental employment may be problematic for some adolescent children. 相似文献

This article examines the extent to which the 2006 revisions to the EU's Generalised System of Preferences improved market‐access opportunities for developing‐country agro‐food exports. It shows that they resulted in only a slight increase in the percentage preferential margin, but that there has been a significant increase in the value of preferential trade and of the preferential margin enjoyed by exporters. This was accompanied by changes in the ranking of beneficiaries. Countries such as China, Brazil, Argentina, India and South Africa maintained their significant shares of GSP agro‐food exports, but other countries such as Thailand and Vietnam have now emerged as major GSP beneficiaries. 相似文献

Abstract This paper examines various psychoanalytic conceptions of trauma, including ideas associated with classical psychoanalytic theory, object‐relations theory, self‐psychology and continuous construction theory. Clinical issues germane to the psychotherapy of children are then discussed and a clinical vignette presented. The vignette focuses upon the psychotherapy of a 10‐year‐old boy, with particular attention given to the narrative discourse that evolved in the course of the boy's therapy. The evolution of the child's narrative is illustrated through the use of transcribed material derived from different phases of the boy's treatment. 相似文献
