Foot and mouth disease (FMD) is considered by many as the most important animal disease in the world. FMD is highly contagious and outbreaks incur significant costs as affected countries are severely limited in their ability to trade. A number of trade commodities may be contaminated with FMD virus (FMDV) including animal products, for example, meat. As a member of the European Union, Great Britain (GB) has put in place a number of regulations to prevent the importation of pathogens in imported meat products. However, the illegal importation of meat provides a route by which safety controls may be circumvented and meat from FMD affected areas may be imported. This study assesses the FMD infection risk posed to the livestock population of GB from the illegal importation of meat, and estimates the major contributors to this overall risk, through the development of a quantitative risk assessment model. From model results, the total amount of illegal meat entering GB each year is estimated on average to be 11,875 tonnes. with 90% certainty that this is between 4,398 and 28,626 tonnes per year; of which between 64.5 and 565 kg are contaminated with FMDV. This flow of illegal meat results in an estimate of a frequency of FMD infection in GB livestock of 0.015 cases of infected animals per year, with 90% certainty it is between 0.0017 and 0.053. Imports from the region Near and Middle East account for 47% of this risk, and 68% of the risk is attributed to bone-in and dried de-boned products.  相似文献

Changes in working time have important economic, social and environmental implications. However, research on workers' preferences is highly fragmented across disciplines and journals. To overcome this, the present article provides a systematic review of the literature, analysing 173 studies. The study shows that working-time outcomes and mismatches are mostly studied in a small group of OECD countries, using survey data and statistical methods. The most clear and consistent results are about gender, care responsibilities and current working hours. Among professions, only the medical workforce receives substantial attention. Norms and preference formation are poorly understood, and more qualitative research is essential to understand how working-time reductions could spread.  相似文献

We use data from the Fragile Families and Child Wellbeing Study (N = 12,140 person-waves) to identify characteristics associated with mothers' having or lacking "personal safety net" support from family and friends. We focus on characteristics that are likely to increase the importance of having support available but may also interfere with the maintenance of supportive ties: poverty, poor physical and mental health, and challenging child rearing responsibilities. By capitalizing on distinctions among these types of personal disadvantages and among types of personal safety nets (financial, housing, child care, and emotional), we help to explain why personal disadvantages are associated with weaker support. Our paper contributes to the literature emphasizing the importance of reciprocity in support relationships and introduces the idea that families that are more difficult to help will have less support available.  相似文献

This paper provides a empirical evidence that the financial intermediation disturbances can generate business cycles. We examine three countries whose financial sectors are fully developed but quite distinct in their institutional and regulatory circumstances; thus, we can infer whether financial intermediation disturbances differ across dissimilar financial environments. We find that the dynamic responses of output to financial intermediation shocks exhibit similar patterns in all cases studied. However, the various institutional and regulatory circumstances have generated different propagation mechanisms transmitting the financial disturbance to output in ways that lead the magnitudes of the responses to deviate across economies.  相似文献

This article, a follow-up on our methodological review of infidelity studies, provides a substantive review of the research findings on infidelity in committed relationships. The aim of this article is to present the most conclusive findings available to both researcher and practitioner on the subject of infidelity. We highlight attitudes toward infidelity; prevalence data; types of infidelity; gender dynamics and infidelity; issues in the primary relationship and their relationship to infidelity; race, culture, and infidelity; education, income, employment, and infidelity; justifications for infidelity; individual issues and their relationship to infidelity; same-sex couples and infidelity; attachment and infidelity; opportunity and infidelity; the aftermath and recovery process from infidelity; and clinical practices.  相似文献
