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

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

The developmental interplay between identity and adjustment was examined in a seven‐wave longitudinal study of 428 European female college students (Mage=18.8 years) over a period of 3 years, with semi‐annual measurement waves each year. Latent Class Growth Analysis (LCGA) was used to identify developmental typologies of both identity formation (i.e., dimensions of commitment and exploration) and adjustment (i.e., depressive symptoms and self‐esteem). Four trajectory classes emerged for identity, three of which had been suggested earlier in the literature ( Josselson, 1996 ): Pathmakers, Guardians, and Searchers. The fourth trajectory class was labeled Consolidators and consisted of individuals characterized by a strong focus on strengthening their current identity commitments, at the expense of a thorough exploration of alternative options. Three trajectory classes were identified for adjustment: Optimal Adjustment, Moderate Adjustment, and Stable Maladjustment. Each of the four identity trajectory classes was associated with a specific profile of adjustment, with the Searchers showing the poorest profile and the Pathmakers and Consolidators the most positive profile. Practical implications and suggestions for future research are outlined.  相似文献

The transmission of longevityor post-reproductive survival from parents tooffspring is investigated using data ondemographic and socio-economic characteristicsof the inhabitants of a small Flemish village(Moerzeke) over a period of three hundredyears. This research confirms the possibleexistence of biological mechanisms intransmitting longevity from parent tooffspring. However, this finding can only beobserved for men and women belonging tospecific birth cohorts (mainly those men bornbetween 1821 and 1860 and those women bornbetween 1791 and 1830). Furthermore, thesex-specificity of the transmission, which waspresent in other studies, is not found in thisresearch. Both factors indicate that theimportance of one's biological potential forlongevity can only be realized in specificsocietal conditions.  相似文献

Using panel data of Dutch first marriages with children (N Time 1=646, N Time 2=386), the relevance of economic and cultural factors in understanding marital satisfaction is examined. The sample was middle-aged and the average marital duration was 17 years (at Time 1). Besides, couples mainly represent single earner and main-earner households. Our results demonstrate that both economic and cultural factors are valid in understanding marital satisfaction. However, whereas cultural characteristics are more important explaining spousal marital satisfaction at Time 1, economic indicators are important predicting change in marital satisfaction. An interaction effect between cultural and economic factors was found as well. Husbands’ familialism moderates the effect of women’s employment on women’s marital satisfaction at Time 1.Ann Van den Troost, Center for Population and Family Research, Department of Sociology, Catholic University of Leuven, Van Evenstraat 2B, 3000 Leuven, Belgium; e-mail: ann.vandentroost@soc.kuleuven.ac.beAd A.
