日本树立伪蒙疆政权后,为了掠夺该地区丰富的畜产资源,实行畜产统制政策。羊毛统制是畜产统制的核心,即对绵羊的增产改良、羊毛的收购、对外输出等,实行强制性的政府指导、控制措施。其中,绵羊改良是羊毛统制政策的重点之一。为了获取重要战略资源羊毛,日本将该地域作为大陆绵羊改良的基地,通过伪蒙疆政府、日系企业、蒙古绵羊协会等组织对肉、皮兼用型的蒙古原种绵羊进行改良,实质是为日本的对外侵略扩张提供羊毛这一急需的战略资源。  相似文献

全球化进程下,跨国移民成为不同地域间文化交流、冲突和再协商的主要载体,其在地饮食适应问题尤为凸显。本文回顾了国内外跨国移民饮食适应的研究,发现由营养学等范式主导的早期研究偏重对饮食适应水平的直接观测,较少探究饮食适应的身体属性、地方关系以及文化意涵。文化地理学视角下的跨国移民饮食适应的相关研究进展主要包括以下三个方面:身体尺度下的动态饮食适应过程、地方尺度下跨国饮食景观的生产与重构,以及身体与地方交互尺度下饮食适应与身份认同的复杂关系。本文最后针对当前研究的主要不足提出未来跨国移民饮食适应研究的可能议题。  相似文献

While food allergy prevalence has been studied at the national level, we know little of food allergy prevalence or perceptions of prevalence/management at the local level. This paper uses Waterloo Region as a case study to 1) document self-reported individual and household food allergy and sensitivity prevalence at the local level; 2) investigate perceptions of food allergy prevalence; and 3) explore perceived confidence in anaphylaxis management. Survey data were collected from January to March 2019. Respondents (n = 500) self-reported individual and household food allergy and sensitivity, estimated the percentage of Canadians with food allergy, and were queried about their knowledge of food allergy management. Prevalence estimates were weighted to the structure of the 2016 Canadian Census, and univariate and bivariate analysis were conducted. Prevalence of self-reported food allergy was 12.1% (95%CI, 8.8%-15.3%), and prevalence of self-reported food sensitivity was 26.3% (95%CI, 21.9%-30.7%). When asked to estimate the percentage of Canadians with food allergy, the mean perceived percentage was 35.1% (SD = 22.96). Self-reported prevalence of food allergy appears higher in Waterloo Region, and the estimated percentage of Canadians with food allergy is inflated. Understanding prevalence and perceptions at the local level is important for targeted allocation of public health resources to ensure safe spaces for individuals with food allergy.  相似文献

There is growing geographical interest in the nature of the 'real' regulation of the food system. The food 'scares' of the late 1980s in the UK encouraged new legislation relating to food hygiene and safety. Its local implementation created tensions which were exacerbated by the legislative consequences of the Single European Market. In response, national-level regulatory adjustments followed, which introduced new codes of practice and techniques of hazard analysis for implementation at the local level. The result was a consolidation of a system of food regulation that can be applied differentially across the 'tiers' of retailing. This paper explores the regulatory contentions of the early 1990s in the food policy arena and the nature of food regulation at the local level. It advances our understanding of the 'construction' of food quality and safety within the UK. Moreover, we argue that its depiction of the dialectical response between policy formulation and implementation confirms the need for local, as well as national level, exploration of the nature of the contemporary state.  相似文献

I examine the role of food, eating, and meals in the life of St. Francis of Assisi. I observe that his experience significantly differs from that of the female fasting saints. I show that his concern lies with the justifiability of eating, and that food is associated with dramatic lessons that instruct or chastise others. I argue that, like Christ, Francis uses food and eating to teach, to share a message, or to accept outsiders.  相似文献

Fermentation is a common method of processing and preserving breadfruit throughout the Pacific Islands. While these pits are often reported in the archaeological record, they can pose some interpretive challenges. This paper presents an analysis of probable archaeological breadfruit (Artocarpus altilis (Parkinson) Fosberg) fermentation pits on Temwen Island, Pohnpei, Micronesia. Using the existing ethnographic record as a guide, I present archaeological and paleoethnobotanical criteria for identifying fermentation features. Architectural and stratigraphic analyses from four excavated pits match ethnographic expectations. Phytolith analysis shows some concurrence in terms of taxonomic data, but is more useful for indicating disturbance specific to building activities. Based on the distribution and size of pits present in the survey area, I suggest that breadfruit fermentation took place as primarily a household level (rather than community level) activity during the late prehistoric and early historic period in Pohnpei.  相似文献

Drawing from 18 months of ethnographic fieldwork in Washington, DC, this article outlines geographies of self‐reliance; a theoretical framework for understanding black food geographies that are embedded in histories of self‐reliance as a response to structural inequalities. Using a community garden as a case study, I argue that the garden functions as a site for addressing several manifestations of structural violence: racist and classist depictions of low‐income and working class people, joblessness, gentrification, and youth underdevelopment. Drawing on self‐reliance ideologies as well as collective and personal histories, the residents exhibit a form of agency that demonstrates unwavering hope in the sustainability of their shared community. Through this analysis, I show that self‐reliance functions as a mechanism through which residents navigate spatial inequalities.  相似文献

Abstract

Famines in the years immediately after World War II occurred during a period of global flux, as international famine response evolved from its ambitious, early twentieth century goals toward more modest, technocratic objectives during the second half of the century. For economists, social scientists and politicians immersed in the world of emergency food aid, these were uncertain, awkward years for famine relief. Herbert Hoover’s idealistic large-scale projects of famine relief that had dominated the first three decades of the century had been proven to be expensive and of limited efficacy, but Cold War loyalties had not yet taken over as the primary logic behind large-scale humanitarian assistance projects. Ultimately, when faced with famine conditions between 1944 and 1947, states and experts balanced a call to action against pragmatism that recognized famines were also politically expedient events that could weaken rural resistance to governance and simplify wartime and postwar administration. Ultimately, both science and humanitarian concerns learned to orient themselves toward economic expediency in these awkward years.  相似文献

Abstract

A consistent access to food is paramount for humans at individual and group level. Besides providing the basic nutritional needs, access to food defines social structures and has stimulated innovation in food procurement, processing and storage. We focus on the social aspects of food storage, namely the role of cooperation for the emergence and maintenance of common stocks. Cooperative food stocks are examined here as a type of common-pool resource, where appropriators must cooperate to avoid shortage (i.e. the tragedy of commons). ‘Food for all’ is an agent-based model in which agents face the social dilemma of whether or not to store in a cooperative stock, adapting their strategies through a simple reinforcement learning mechanism. The model provides insights on the evolution of cooperation in terms of storage efficiency and considering the presence of social norms that regulate reciprocity. For cooperative food storage to emerge and be maintained, a significant dependency on the stored food and some degree of external pressure are needed. In fact, cooperative food storage emerges as the best performing strategy when facing environmental stress. Likewise, an intermediate control over reciprocity favours cooperation for food storage, suggesting that concepts of closed reciprocity are precursors to cooperative stocks, while excess control over reciprocity is detrimental for such institution.  相似文献

Over the past 15 years social movements for community food security, food sovereignty, and food justice have organized to address the failures of the multinational, industrial food system to fairly and equitably distribute healthy, affordable, culturally appropriate real food. At the same time, these social movements, and research about them, re‐inscribe white, patriarchal systems of power and privilege. We argue that in order to correct this pattern we must relocate our social movement goals and practices within a decolonizing and feminist leadership framework. This framework challenges movement leadership and scholarship by white people who uncritically assume a natural order of leadership based on academic achievement. We analyze critical points in our collaboration over the last four years using these frameworks. Doing so highlights the challenges and possibilities for a more inclusive food justice movement and more just scholarship.  相似文献
