To address the persistent problems of foodborne and zoonotic disease, public health officials worldwide face difficult choices about how to best allocate limited resources and target interventions to reduce morbidity and mortality. Data‐driven approaches to informing these decisions have been developed in a number of countries. Integrated comparative frameworks generally share three methodological components: estimating incidence of acute illnesses, chronic sequelae, and mortality; attributing pathogen‐specific illnesses to foods; and calculating integrated measures of disease burden such as cost of illness, willingness to pay, and health‐adjusted life years (HALYs). To discuss the similarities and differences in these approaches, to seek consensus on principles, and to improve international collaboration, the E.U. MED‐VET‐NET and the U.S.‐based Food Safety Research Consortium organized an international conference convened in Berlin, Germany, on July 19–21, 2006. This article draws in part on the deliberations of the conference and discusses general principles, data needs, methodological issues and challenges, and future research needs pertinent to objective data‐driven analyses and their potential use for priority setting of foodborne and zoonotic pathogens in public health policy. 相似文献

Increasingly, partnerships and other cooperative forms of governance are common-place in addressing problems of environmental management in rural landscapes. These forms of governance are multi-dimensional in the policy instruments employed; the make-up of actors; and, the types of rationalities that actors use to debate the problem and proposed solutions. This paper pursues the question of how different modes of social action, represented in argumentative claims of participants, influence social coordination in these governance arenas. An empirical study is presented of agri-environmental governance in Australia where actors debate planning and policy initiatives to reduce diffuse water quality impacts from farms on the adjacent Great Barrier Reef. Forester’s conceptualisation of practical social action which locates communicative action in the ‘real world’ of interest-based planning contexts, is used as an analytical frame to identify: (i) the type of claims made by governments, farmer groups and other actors in argumentation; (ii) the claims association with communicative, strategic and instrumental modes of action; and, (iii) their consequence for social coordination in formation and maintenance of inclusive, legitimate and viable forms of governing. The study finds that the interconnected character of claims made by actors, and the ready switching between modes of action observed, point to a situated and dynamic expression of rationality within these contested and prolonged debates on how to legitimately and effectively govern rural environments. 相似文献

Under simple random (multinomial) sampling the problem of estimating cell proportions for a contingency table subject to marginal constraints has been well explored. We briefly review methods that have been considered; then we develop a general method, for more complicated sampling, which reflects the variance structure of the estimated cell proportions. For stratified and cluster sampling we compare our method against earlier methods for the 2×2 table and find it potentially advantageous. 相似文献

In recent years in social work we have increasingly come to address the issue of how to integrate research into practice. Implicit in the research and practice discourse is an assumption that there is an active and reciprocal relationship between research and teaching. In this paper, we question this assumption and after setting the political context, we review research into the relationship between discipline-based research and teaching. We then explore a proposal to redefine knowledge, research and teaching and examine the concept of scholarship. We go on to review some strategies we will be promoting in the UK Higher Education Funding Council's Learning and Teaching Network Support (ltsn) Social Policy and Social Work Subject Centre (SWAP) to support the development of positive linkages between teaching and discipline-based research, specifically on-line possibilities for supporting research mindedness among academics (and students and practitioners). Finally, we end by briefly discussing the equally important integration of pedagogic research into the practice of teaching. 相似文献

Role‐play (i.e., pretending in which children imagine and act out the part of another individual) was assessed with child interviews and parent questionnaires about invisible friends, personified objects, and pretend identities in a sample of 208 young children. Children who engaged in role‐play did not differ from other children in age or vocabulary comprehension. However, they were better able to generate a pretend conversation than other children and were rated by their parents as less shy. The overall pattern of results suggests that the capacity to interact with imaginary others (in and out of the lab) is more closely associated with individual differences in personality than developmental level. 相似文献
