Fish for Dinner? Balancing Risks,Benefits, and Values in Formulating Food Consumption Advice

Many and complex factors underlie seemingly simple decisions about what to eat. This is particularly so for foods such as fish, which present consumers with both risks and benefits. Advice about what type of and how much fish to consume is abundant, but that advice is often confusing or contradictory, reflecting the differing mandates and orientations of those advising. We survey a range of issues that can and should be incorporated into dietary advice, and offer tools for health agencies tasked with providing it. We argue that risks and benefits should not be limited to direct physical health. Rather, socioeconomic and community factors, unintended or indirect effects, and nonhuman‐health outcomes such as animal welfare and planetary health should also be considered and weighed. We provide examples of existing fish consumption guidance to highlight the conflicting messages that emerge when different sources of advice with singular aims of avoiding risk, gaining nutritional benefit, or sustaining fish populations are juxtaposed. We then offer tools borrowed from health and other fields to guide health agencies toward developing more comprehensive advice and targeting that advice for specific populations. 相似文献

AbstractWomen typically hold jobs in which they experience less pay and less favorable working conditions than men in comparable positions. Despite these differences, women report similar or even higher levels of work satisfaction. Most studies explaining work satisfaction and gender focus on workplace rewards as potential explanatory variables. Little is known about the relevance of support resources from the family domain in relation to women’s and men’s work satisfaction. Finally, the relevance of support resources has not been studied in high-status professions where women have quickly become more highly represented numerically. Using quantitative survey data from a sample of married veterinary doctors (N?=?311), we explore the influence of work and family-based support resources. Specifically, we examine the relationship between work satisfaction and three sources of support: coworkers, family, and spouses. We also explore whether parental status has moderating effects for women and men with these resources in association with work satisfaction. We find that mothers are more satisfied than fathers. Parenthood and supportive family engagement are strong predictors of women’s work satisfaction. Coworker support is a salient predictor of work satisfaction for all, especially for men who are fathers. Implications for men and women working in high-status professions are discussed. 相似文献

The undisciplined youth is one figure that is key to understanding the 1950s and 1960s in India. Politicians, officials, academics, youth leaders, and journalists developed and spread a discourse that imagined the collective behaviour of Indian youths as falling well below adult expectations of them in independent India. The imagery of the youth lacking in discipline was tied up with cycles of student unrest and the idea that the methods of protest used during the pre-independence period had wrongly continued into the post-independence period, but this discursive formation was often extended to include all Indian youths and it became translated into a long-term anxiety about the future of the newly established nation-state. These tropes about the undisciplined Indian youth became a symbol of the country's unresolved future. Unless the crisis of youth could be remedied, the narrative went, then the potentiality of Indian independence and its first generation of citizens could never be realised. This discourse took on a novel and distinctive shape during the initial years following Indian independence in 1947, it crystallised during the early 1950s, and there was a continued build-up of public concern that lasted throughout the 1960s. 相似文献

This article explores how strategies of thinking and working politically are used by agencies within developing country governments to influence wider government agendas. It uses research on climate change mitigation in China and India to explore how government agencies seek to overcome challenges of limited capacity and competing priorities by bundling climate change together with more immediate priorities and thereby developing a coalition with an interest in achieving these objectives. The article is based on interviews conducted in China and India, as well as analysis of themes covered in the growing body of literature on the domestic politics of climate change mitigation. In both countries we found that pragmatic approaches leveraging what already exists made significant progress in putting energy efficiency on the agenda, strengthening institutional presence (in India) and delivering improvements in energy efficiency (in China). Yet, we also found that the use of these tactics had significant limitations. While there was probably no other way that the policy space given to climate change mitigation could have increased so rapidly, there are significant side effects that arise as a result of the traction gained by these initial policy approaches. While bundling raised the profile of energy efficiency, it also created perverse incentives that highlight the need to consider the long‐term effect on the interests, capacity and sustainability of informal coalitions. We highlight the need to take account of both the short‐ and long‐term effects of thinking and working politically, and the challenges of doing so when the outcomes are unpredictable and inherently difficult to assess. 相似文献

This chapter examines the societal drivers of environmental change in South Florida's Everglades region during the past 150 years. This historical geography is developed through the use of a conceptual framework constructed to facilitate the analysis of human–environment interactions and nature–society systems of ecological degradation and restoration at the regional scale. The framework is composed of four basic interlinked components: interaction mechanisms (e.g., land use, direct resource utilization, pollution and external inputs, resource competition), feedback mechanisms (e.g., basic needs, quality of life, environmental ethics), control systems (e.g., governmental regimes, legal institutions, resource management), and the societal context (e.g., population and demographic patterns, social structure and organization, technology, economic conditions, societal values). A primary objective of this chapter is to determine the presence and importance of each of these components during the process of environmental change over the period of study—1845 to 1995.Data for the analysis are drawn from primary and secondary sources on the environmental, social, economic, and political history of South Florida. The results indicate that although elements of each component were present throughout the entire period, different elements of each component play more significant roles at differing moments. The shifts in importance are used to define four periods of environmental change within the region. The periods are the following: (1) frontier settlement (1845–1900), focused on basic needs acquisition and direct utilization of the resource base; (2) drainage and land conversion (1900–1930), focused on population and economic growth, land use change, and increased resource management and competition; (3) flood control and consolidation (1930–1950), focused on inputs from external sources and infusion of advanced technology, the development of governance and social structures, and increased concern for quality of life; (4) postwar boom, flood control, and water supply (1950–1970), focused on accelerated land use change, increased pollution, and further heightened concern for local quality of life; and (5) period of limits (1970–1995), focused on pollution and resource competition concerns, a developing regional environmental ethic and amenity values, and environmental preservation governance strategies.Taken together, the five periods represent the differing nature–society systems through which South Florida's regional ecosystem was degraded and which is now entering a phase of restoration. 相似文献

Assisted reproduction has a minor but increasing influence on childbearing trends in advanced societies. In Denmark, the use of assisted reproduction technology (ART) has become particularly widespread. At the same time, Danish women born in the late 1950s and the 1960s experienced stabilization or even a slight increase in their mean number of children. Broad availability and widespread use of assisted reproduction may become important factors contributing to maintaining relatively high completed fertility among the younger cohorts of Danish women. To explore this idea, we analyze and project cohort trends in fertility rates among native Danish women born in 1960‐78 and examine the likely contribution of assisted reproduction to these trends. The projected proportion of children born after ART treatment shows a substantial increase from 2.1 percent among women born in 1965 to 4‐5 percent among women born in 1978, with an estimated net impact of ART (as compared with the hypothetical situation where no ART treatment was available) on the order of 3‐4 percent. When intrauterine inseminations are included, this implies that up to 7 percent of children of those native Danish women born in 1975 and later will likely be conceived by infertility treatment. 相似文献

In recent years fertility statistics in the Australian Bureau of Statistics (ABS) publication Births, Australia have suffered from a number of issues, including delayed receipt of registration data from the Registrars and computer processing errors. They prompt questions about the quality of these statistics for measuring the level of fertility and its year-to-year changes. The aim of this paper is to compare three sets of fertility statistics, (1) ABS birth registrations, (2) ABS births by year of occurrence, and (3) births in the Australian Institute of Health and Welfare National Perinatal Data Collection (NPDC), at the national and state/territory scales. Annual births by state/territory of usual residence from the three data sources were obtained for the period 2004–2013 or 2004–2014. Recast Estimated Resident Populations from the ABS were used to calculate Total Fertility Rates. For some states and territories there are non-trivial differences in fertility as recorded by the three data sources. In Queensland the trend in fertility according to ABS birth registrations is quite different from that based on the NPDC; in Tasmania and the Northern Territory birth registrations exceed NPDC births by a notable margin. There appears to be more uncertainty about the levels and annual changes in Australian fertility than many users of the data may realise. All three fertility datasets seem to possess some limitations. It is suggested that a new Australian fertility database be created which employs data linkage to incorporate both birth registrations and perinatal data. 相似文献

In their review of Internet gambling studies, Auer and Griffiths (J Gambl Stud 30(4), 879–887, 2014) question the validity of using bet size as an indicator of gambling intensity. Instead, in that review and in a response (Auer and Griffiths, J Gambl Stud 31(3), 921–931, 2015) to a previous comment (Braverman et al., J Gambl Stud 31(2), 359–366, 2015), Auer and Griffiths suggested using “theoretical loss” as a preferable measure of gambling intensity. This comment extends and advances the discussion about measures of gambling intensity. In this paper, we describe previously identified problems that Auer and Griffiths need to address to sustain theoretical loss as a viable measure of gambling intensity and add details to the discussion that demonstrate difficulties associated with the use of theoretical loss with certain gambling games. 相似文献

Guided by relationship theory, this study develops and tests abbreviated operational definitions of communicated commitment and conversational voice as communicative strategies in maintaining organization-public relationships (OPRs). Researchers first identified 25 relational maintenance items from 12 prior published studies. Then surveying three independent subsamples of an organization’s key public (N = 1,169), the distilled list revealed two univariate concepts measured with a total of 11 items. The shorter scales make the measurement and evaluation of communication online and real-world activities more accessible and manageable for practitioners and academics focused on organization-public relationships. 相似文献
