Public school lunch programs in the United States are contested political terrains shaped by government agencies, civil society activists, and agri-food companies. The particular organization of these programs has consequences for public health, social justice, and ecological sustainability. This contribution draws on political economy, critical food studies, and feminist economics to analyze the US National School Lunch Program, one of the world's oldest and largest government-sponsored school lunch programs. It makes visible the social and environmental costs of the “heat-and-serve” economy, where widely used metrics consider only the speed and volume of service as productive work. This study demonstrates that such a narrow understanding of the labor of lunch devalues care and undercuts the potential for school food provisioning to promote ecological and feminist goals. Further, it proposes a “high road” alternative and outlines an agenda for reorganizing school food provisioning to maximize care in all its dimensions.  相似文献

Social media usage by health care organizations has increased dramatically. Findings from this research show that 95% of the top ranked hospitals use social media. The purpose of this study is to examine whether social media usage varies according to size of hospital and types of services provided. Since social media platforms appeal to different groups of people, this prompts the question of whether certain platforms are more appealing to people who partake in different health services. Findings reveal differences in social media usage depending on the services provided by a hospital.  相似文献

This study reports an attempt to validate a customer well-being (CWB) index related to natural wildlife tourism. It was hypothesized that the CWB index related to wildlife tourism has a positive influence on travel outcomes (length of stay, number of visits, and total expenses), mediated by perceived value and customer loyalty. These hypotheses were tested using four waves of surveys of customers (overnight visitors) intercepted at the park in a two-year period. The survey data provided support for the hypotheses, which, in turn, lend validation support to the CWB index. Managerial implications of the customer well-being index are also discussed.  相似文献

Taxes to reduce the consumption of sugar-sweetened beverages (SSBs) such as soda drinks have been endorsed by the World Health Organization and are now in place in France, Hungary, and Mexico, and scheduled for Portugal, South Africa, and Great Britain. Such taxes have so far been impossible to enact in the United States at the state or federal level, but since 2014 seven local jurisdictions have put them in place. Three necessary conditions for local political enactment emerge from this recent experience: Democratic Party dominance, external financial support for pro-tax advocates, and a political message appropriate to the process (public health for ballot issues; budget revenue for city council votes). Roughly 40 percent of Americans live within local jurisdictions where the Democratic Party dominates, so room exists for local SSB taxes to continue spreading.  相似文献

Abstract

This article analyses reforms to contracting and accountability for indigenous primary health care organizations in Canada, New Zealand, and Australia. The reforms are presented as comparative case studies, the common reform features identified and their implications analysed.

The reforms share important characteristics. Each proceeds from implicit recognition that indigenous organizations are ‘co-principals’ rather than simply agents in their relationship with government funders and regulators. There is a common tendency towards more relational forms of contracting; and tentative attempts to reconceptualize accountability. These ‘frontier’ cases have broad implications for social service contracting.  相似文献

On-the-go (OTG) consumption is a growing phenomenon in the food and beverage industry. Drawing on the theory of consumption values, this study is conducted to acquire a better understanding of the influence that retail-mix elements have on OTG consumption outcomes. Specifically, this study examines the role of value for money, customer service, general assortments and healthy assortments in driving intention and satisfaction related to OTG consumption. The study also assesses the conditional value generated by the consumer's health orientation, impulsiveness and perceived time pressure. Based on a sample of 433 OTG consumers, and applying multi-group structural equation modelling (SEM) and fuzzy-set qualitative comparative analysis (fsQCA), value for money was identified as the key driver of OTG consumption outcomes. Impulsiveness and time pressure are shown to increase the effects of value for money perceptions on OTG consumption intention, while health orientation enhances the relationship between customer service and satisfaction. This study contributes to the literature on OTG consumption, explains the managerial implications for retailers, and offers recommendations to target OTG consumers better.  相似文献

In public policy planning and budgeting, the health issues and homeless issues tend to be interrelated and reinforced by each other, but this mutual causality is usually ignored in the existing literature. This paper provides an unbiased estimate of a structural equation model taking endogeneity into account. A questionnaire is designed based on the health-related quality of life (EQ-5D) framework and is given to 322 homeless individuals. Evidence shows that, without timely support, the homeless state and health state will fast deteriorate and reinforce each other. It is therefore arguable to broaden the definition of statutory homelessness, and the “preventative approach” can save, rather than increase, the public resources spent on the homeless.  相似文献

The disproportionate concentration of healthcare professionals in urban areas is a concern in many countries, including Canada. A need to address this rural care gap has driven a large number of government led initiatives worldwide over the years. This paper presents a model that can be used as a tool to examine the efficacy of such policies on the workforce distribution in the long term. A small system dynamics model is employed to simulate the current and future distribution of general physicians at a jurisdictional level. The model represents the transition of general practitioners to provide insight into the dynamics of care provision over time. The movement, and competition, between rural and urban areas is modeled to enable detailed exploration of the ability for proposed measures to alleviate the care gap in the future. Among the tested policies are such commonly used initiatives as financial incentives to rural professionals, promotion of medical education in rural areas, expansion of rural education programs and the engagement of international medical graduates etc. We demonstrate how the model can be used as a tool to determine an efficient and well-chosen combination of policies which can help alleviate the rural care gap in the future, given that some policies are more effective than others alone but also combined with other initiatives. The presented small system dynamics model is tested on Canada's reality, but its simple nature lends itself to easy application to other countries that experience a similar problem.  相似文献
