Objective: Functional foods (FF)—foods containing nutritional supplements in addition to natural nutrients—have an increasing presence in the marketplace. Expanding on previous research, the authors investigated college students' acceptance of FF. Participants: In September-March 2004, 811 undergraduates in Canada, the United States, and France participated in the study. Methods: A self-administered questionnaire measured students' general food attitudes and beliefs as well as FF-related knowledge, attitudes, beliefs, and purchase intention. Results: Overall, participants slightly favored FF over traditional foods. However, although most respondents associated FF with positive health benefits, many remained dubious of currently available FF information. In terms of culture and sex, the authors found small but significant divergences in FF knowledge, attitudes, and behaviors. Conclusions: Stronger labeling and education efforts may increase cross-cultural acceptance of FF by college students.  相似文献

目前,加强我国食品安全立法势在必行,而食品责任强制保险立法当属其中。尽管《食品安全法》加强了有关食品安全的规定,但是并没有规定食品责任强制保险,因此研究食品责任强制保险制度意义重大。对食品责任强制保险的内涵、特征及必要性进行分析,明确食品责任强制保险的保险人、投保人、第三人以及保险限额和保险期限等问题,对我国食品责任强制保险立法提出相关建议。  相似文献

Connecting wider economic, technological, or cultural trends to the everyday life of students can be a challenge. Food can serve as a course-long theme that helps students comprehend the essential connection between personal actions and national or international trends and develop skills of critical analysis. The author describes four activities that can be adapted to a wide variety of social studies courses and age groups. In the first two activities, students gain an understanding of their diet by exploring their food choices and the factors that affect those choices. These activities provide a point of comparison for subsequent units in which students examine food choices in a pre-industrial age and the impact of the technological advances of the Industrial Revolution on food production, preservation, and preparation.  相似文献

ABSTRACT

Several recent studies have indicated that patients who report a history of sexual abuse, on the basis of recovered or delayed recall of memory, process Rorschach stimuli in ways that substantially deviate from non-abused patients. They exhibited sensitivity to threat-relevant imagery that was highly similar to the biased perceptual processing found among patients with continuously held memories of sexual abuse. In the present study, perceptual processing of threat-relevant imagery was examined as an artifact of media exposure in 40 patients who recovered memories of childhood sexual abuse as adults and in 40 patients who were not sexually abused. The two patient samples were divided into high and low media groups on the basis of a composite measure of media exposure. The results indicated that information gained from media exposure was unrelated to patients' responses to Rorschach stimuli. Recovered memory patients produced threat-relevant imagery that is reminiscent of trauma irrespective of the level of media exposure; non-abused patients did not. That this imagery remained essentially unnoticed by even the most active consumers of the sexual abuse media among non-abused patients suggests that the popular media does not play a contagious role in the perceptual processing of threat-relevant imagery.  相似文献

Access to nutritious foods is limited in disenfranchised communities in the United States. Policies are beginning to focus on improving nutritious food access in these contexts; yet, few theories are available to guide this work. We developed a conceptual model of nutritious food access based on the qualitative responses of food consumers in 2 different regions of the American South. Five domains (economic, service delivery, spatial–temporal, social, and personal) and related dimensions of nutritious food access were identified. The conceptual model provides practical guidance to researchers, policy makers, and practitioners working to improve nutritious food access in communities.  相似文献

The US campaign for ‘pure food’ from the 1880s through 1906 featured a diverse coalition of groups with quite different ways of defining the problem, identifying the relevant actors, and balancing political and consumerist tactics. This paper examines how these differences in framing, rather than undermining cooperation or impeding success, helped to broaden the coalition for pure food and to win passage of the 1906 Food and Drug Act. It pays particular attention to the ways in which women's groups acted as frame brokers, translating pure food issues into a maternalist language and, in so doing, contributing both new support and new tactics to the campaign. The case study is used to address more general issues in the relationship between framing and (1) coalition-building and (2) tactical repertoires.  相似文献

Recently there has been a marked shift reflecting increased theoretical interest and political practices embracing strategies of localism or relocalization against neoliberal globalization. Specifically, individuals, farmers, and communities embracing the framework of food sovereignty have increasingly adopted localism tactics in response to the globalization of food systems, the corporate agribusiness model, and attendant food crises. The spread of the food sovereignty concept from the global peasants' movement Vía Campesina to locales as diverse as industrial France and the rural state of Vermont in the United States demonstrates the way in which food sovereignty has been appropriated in different international settings. Additionally, the turn toward localism merits further scrutiny as a reflection of an unsettling of forms of collective resistance at a moment of structural crisis in global capitalism. Localism as an alter-globalization tactic is still overshadowed by protest summitry and large-scale mobilizations, when small-scale micro-encounters arguably are part of a growing, broader, and more nuanced process of transnational diffusion of resistances, struggles, and reformulations over sovereignty at multiple political and social scales.

Recientemente ha habido un cambio que se refleja en el incremento de un interés teórico y prácticas políticas, que incluyen estrategias de localismo o relocalización contra la globalización neoliberal. Como táctica de respuesta a los sistemas de globalización alimentaria, a los modelos agroindustriales corporativos, y a las crisis alimentarias, los individuos, agricultores y comunidades responden abogando por la soberanía alimentaria, adoptando mecanismos locales. La propagación del concepto de soberanía alimentaria que parte de movimientos globales de campesinos ‘Vía Campesina’, en lugares tan diferentes como la Francia industrial y el estado rural de Vermont en los Estados Unidos, demuestra la manera como la soberanía alimentaria se ha apropiado de diferentes ámbitos internacionales. Además, el giro hacia el localismo merece un estudio más detallado, como reflejo de formas inquietantes de resistencia colectiva, en un momento de crisis estructural del capitalismo global. El localismo como una táctica alterna a la globalización, está todavía opacado por las protestas de las cumbres y las movilizaciones a gran escala, sin embargo los micro-encuentros son sin duda, parte de un proceso creciente, más amplio y con más matices, de la difusión trasnacional de las resistencias, los conflictos y la reformulación de la soberanía, a múltiples escalas políticas y sociales.

最近有一个明显的转向,反映出以地方主义或再地方化抵制新自由主义全球化的理论兴趣和政治实践在增长。具体来说,拥护粮食主权的个人、农民和社群越来越多地采用地方化策略来应对粮食体系全球化、公司化农业经营模式化和随之而来的粮食危机等。从全球性农民运动“农民之路”到地方如工业化的法国和美国农业州佛蒙特,粮食主权这一概念广泛传播,表明其已在不同国际场合被认可。此外,在全球资本主义发生结构性危机之时,这一本土化转向作为未成形的集体抵制的一种反映,值得进一步研究。地方化作为改造全球化运动的一种策略,其作用仍然被抗议峰会和大规模群众运动所掩盖,而小规模微观层面的抵抗是正在进行中的更广泛和细微的、在诸多政治和社会层面对主权进行抵制、斗争和重建的跨国扩散过程的一部分。  相似文献

2012年,上海CPI总体呈现出稳步下降的态势,物价涨幅较2011年显著回落。物价上涨势头得到遏制,除了经济增速放缓等客观因素影响,也反应出政府一系列稳定物价的政策措施发挥了积极作用。2013年上海仍要准确把握调控节奏,强化政策落实效果,构建稳定物价的长效机制,把主副食品等价格控制在合理范围内,守住保障市民基本生活的底线。  相似文献
