Nontyphoidal salmonellosis is the second most frequently reported zoonotic disease in the European Union (EU) and is considered to be a major threat to human health worldwide. The most reported Salmonella serovar in the EU is S. Enteritidis, mainly associated with egg contamination, followed by S. Typhimurium, with the latter being the most predominant serovar isolated from pork. These findings suggest that reducing the Salmonella contamination in the pork production might be a good strategy to prevent and control human salmonellosis in the EU. Recently, a quantitative microbial risk assessment (QMRA) has been developed to assess the risks for human salmonellosis due to home consumption of fresh minced pork meat in Belgium.( 1 ) The newly developed risk model is called the METZOON model. In the current study, the METZOON model was used to evaluate the effectiveness of different hypothetical Salmonella mitigation strategies implemented at different stages of the minced pork production and consumption chain by means of a scenario analysis. To efficiently evaluate the mitigation strategies, model results were obtained by running simulations using the randomized complete block design. The effectiveness of a mitigation strategy is expressed using point and interval estimates of the effect size for dependent observations, expressed as the standardized difference in population means. The results indicate that the most effective strategies are taken during the slaughter processes of polishing, evisceration, and chilling, and during postprocessing, whereas interventions in the primary production and at the beginning of the slaughter process seem to have only a limited effect. Improving consumer awareness is found to be effective as well.  相似文献

This literature review analyses the adoption and development of a street‐level perspective in public management, social policy and social work. The last years have seen a prominent revival of a perspective based on Michael Lipsky's street‐level bureaucracy approach in the debates conducted within all three disciplinary fields. Based on 71 key publications in public management, social policy and social work, the review analyses the adoption of the street‐level bureaucracy approach during the period 2005–2015, pointing out the main themes of the debate within, as well as overlaps and differences between, the three disciplines. The findings show the potential of better integrating the different perspectives and taking stock of the articulated debate. Lastly, the review discerns a common viewpoint for further street‐level research, emphasising its importance for the critical analysis and understanding of street‐level work as a vital dimension of responsive and accountable institutions and as a decisive moment to shape positive policy outcomes on the ground. Key Practitioner Message: ? The use of discretion by frontline practitioners and their role as policy actors on the ground has become an important focus of research; ? This literature review shows that the debate has gone far beyond discussing discretion as an all‐or‐nothing issue, pointing out both positive and negative aspects of discretion and developing comprehensive frameworks to explain the use of discretion at the street‐level; ? However, street‐level research has traditionally rather neglected the notion of professionalism. The social work literature brings in the perspective of professionalism; more research efforts are needed to better explore and explain how professionalism matters in relation to challenges and dilemmas of different policy and practice fields.  相似文献

The study aims to assess, first, whether there is a gap in well‐being between unmarried cohabitants and the married, second, if selection factors can explain this so‐called cohabitation gap, and third, if the size of the cohabitation gap differs across countries and how this can be explained. We use pooled data from young adults (18–44) in 3 rounds of the European Social Survey (N ? 31, 500). Multilevel regression analyses show that there is a moderate cohabitation gap that can be partly explained with the selection factors material resources and religiosity. Country differences were clear and could partly be explained with the level of institutionalization: In countries where cohabitation is more accepted and more prevalent, the cohabitation gap is smaller.  相似文献

News media often engage in strategy framing when covering politics, including strategic press and publicity coverage coined to express the focus on the media's role in the game of politics, as well as politicians’ calculated publicity and public relations efforts in relation to the media. This study examines the effect of strategic press and publicity coverage on perceptions of political PR once its practitioners and their publicity efforts have become the object of reporting. Drawing on data from two experiments (n = 863), we show how political PR professionals have themselves little to gain from becoming part of the story.  相似文献

This article adopts a feminist perspective to examine masculine work culture in the development of free/libre open source software. The authors draw on a case study of the ‘Heidi bug’ discovered during the development of the Mozilla Firefox web browser to examine how ‘gendered talk’ was (en)‐acted to facilitate ‘bricolage’ in an online work environment. Such gendered talks contain cultural references familiar to male developers. Though seemingly innocuous, such acts could be seen as a performance of gender that simply reflects the hegemonic heterosexual masculine culture manifested in an online virtual work space. The virtual work space therefore can be exclusive to those who shared the cultural references. Although it may not necessarily be ignorance or insensitivity of male developers, a more gender‐balanced, women‐friendly and inclusive workplace certainly would benefit from a more diverse environment. This article highlights the gendered aspect of software development through examining the language use and mainstream ‘bricolage’ practice, and establishes a compelling ground for enlarging the talent pool to include more women and integrating gender ethics (e.g., raising awareness of sensitive language and design approaches) into computer ethics education.  相似文献

It has become widely accepted that focusing exclusively on income growth may lead to a too narrow-sighted measure of changes in well-being. People care about other dimensions of life, such as their health, employment, social interactions and personal safety. Moreover, an exclusive focus on income growth remains blind to the distribution of income and well-being in the society. We propose therefore a set of five principles for a richer measure of well-being. In particular, we advocate the use of a measure based on “equivalent incomes”, which satisfies these principles. We discuss and illustrate how this equivalent income approach can be implemented in Europe, using the ESS data for 2008 and 2010. We find that introducing inequality aversion and including other dimensions in the analysis leads to a remarkably different perspective on the growth of well-being in Europe.  相似文献

Prior studies have suggested that higher public pensions are associated with lower income inequality among the elderly, whereas the reverse is true for private pensions. Van Vliet et al. ( 2012 ) empirically test whether relative shifts from public to private pension schemes entail higher levels of income inequality among the elderly using panel data from the OECD SOCX and the EU‐SILC databases. Contrasting earlier empirical studies using either cross‐sectional or time‐series data, they do not find evidence that shifts from public to private pension provision are associated with higher levels of income inequality or poverty among the elderly. The aim of the current article is to extend the analysis of Van Vliet et al. by: (1) adding additional countries; (2) adding additionally available years; and (3) using revised OECD SOCX data. In contrast to Van Vliet et al., we find that a greater relative importance of private pensions is associated with higher levels of income inequality and poverty among the elderly. A central explanation of the difference in conclusions stems from the revision of OECD SOCX data.  相似文献
