生态农业与中国未来的粮食安全

随着人们对"石油农业"环境负面影响认识的不断深入,环境友好型的农业生产方式越来越受欢迎。从20世纪90年代"中国生态农业"的提出,到今天遍布全国的生态农业示范基地,生态农业在我国得到迅速发展。然而,保障基本自给的粮食安全一直是我国农业发展的一个重要目标。因此,生态农业能否保障我国的粮食安全成了一个不可回避的问题。在控制影响粮食产量的3个主要投入要素(化肥、化学农药以及水资源)的投入数量后对我国粮食产量进行测算,发现在现有生产条件及资源利用效率的情况下生态农业能保障我国粮食需求量的80%左右,粮食产量高于我国"生存安全标准"的粮食需求量。此外,未来我们提高粮食产量的潜力还很大,再加上通过国际农业合作与贸易发挥我国的比较优势,利用国际市场对粮食品种进行调剂。总之,在生态农业的种植模式下,我国未来的粮食安全能够得到保障。     

我国餐饮零售快餐业态连锁企业发展战略模式研究——基于十家快餐连锁企业分析

通过对十家进入餐饮百强企业名单的快餐业态连锁企业在不同发展阶段的发展模式的信息数据分析,归纳出四种快餐业态发展相对成功的发展战略模式,分别为资本快速扩张型、资本稳健扩张型、加盟稳健扩张型和区域缓慢扩张型。四种发展战略模式在发展方式、发展资本、发展方向、发展速度四方面具有一定差异性。当前我国快餐成功企业共同的发展特征包括主要经营中式快餐、以直营分店扩张为主、采取后向一体化和逐步实现标准化管理四个关键要素。四种发展战略的适应性选择是我国快餐企业成功发展的重要参考,四个关键经营要素的实施是保证快餐企业成功的重要条件。     

食品安全问题存在原因及应对策略研究

从三方面分析了食品安全问题存在原因.社会公众对食品安全问题的容忍度过高;部分食品企业伦理道德缺失,片面追求发展快速而忽视食品安全;一些消费者的消费文化不完善和我国法律的缺陷和监管机制不完善等.针对这些原因,建议对食品安全问题“零容忍”;培育食品企业的伦理道德;提高消费者的消费文化;完善国家法律体系和加大食品安全的监管力度等.认为人民满意是完善法律和提高监管的出发点和落脚点.     

论大豆及相关豆制食品的起源

本文用"二重证据法",征引文献资料,结合新得之地下发掘材料,得出大豆原产于中国、其时间可追溯到距今3000多年的夏代中晚期之结论。同时,考证出中国的战国时代已食用豆豉,西汉时代已食用豆腐。批驳了国外某些学者所谓中国大豆及其豆制食品系从外国传入的谬说。     

Sales and operations planning: responding to the needs of industrial food producers

This paper investigates sales and operations planning (S&OP) at four Scandinavian industrial food producers in order to explore how the use of S&OP might help leaders to deal with the challenges set by the planning environment. Variables connected to the product and market, e.g. frequency of new product development, customer service levels and supply uncertainty, were identified as particularly critical for the S&OP process. It was found that there is great potential for S&OP in the food industry, foremost to cope with the imbalances between demand and supply and to create prerequisites for a stable production process.

Defending Motherhood: Morality,Responsibility, and Double Binds in Feeding Children

The ideology of intensive mothering sets a high bar and is framed against the specter of the “bad” mother. Poor mothers and mothers of color are especially at risk of being labeled bad mothers. Drawing on 138 in‐depth interviews and ethnographic observations, this study analyzes the discursive and interpersonal strategies poor mothers use to make sense of and defend their feeding and children's body sizes. Food beliefs and practices reflect and reinforce social inequalities and thus represent an exemplary case in which to examine intensive mothering, its ties to growing inequality, and how individuals are called to account for it. Findings demonstrate intersecting inequalities, meanings, and contradictions in mothers' accounts of meeting intensive mothering expectations around feeding, health, and weight. In light of moral framings around feeding and weight, mothers' experiences of surveillance, and the double binds they encounter in feeding children, mothers practice what the authors term defensive mothering.     

Regulating without controlling: Children's food and self-management in the U.S. middle class

This ethnography examines how adults in an Atlanta community approached the challenges involved in children's food socialisation and emotional socialisation at large. In both realms, self-management was the ultimate goal. For parents, striking a balance between conscientious attentiveness and offensively controlling behaviours was key. Ultimately, the realm of children's food revealed emotional tensions inherent in middle-class models of selfhood, where both children and adults come under scrutiny for their comportment and tastes, and where careful regulation is deemed both necessary and problematic in ways that work to deflect attention from the compensatory labour of parents in a neoliberal economy.     

Effects of ‘women empowerment’ on household food security in rural KwaZulu‐Natal province

Understanding the dimensions of ‘women's empowerment’ that influence food security among rural households is crucial to inform policy. This study uses the Household Food Insecurity Access Scale (HFIAS) to identify the food security status of 300 primary female‐headed households in Msinga, South Africa. Principal Component Analysis was then used to identify the various dimensions along which the rural women sampled were empowered. Finally, the Ordered Logit model was used to identify the dimensions of women's empowerment that influence their household food security status. It was found that households headed by women with higher levels of economic agency, physical capital empowerment, psychological empowerment and farm financial management skills empowerment were more likely to be food secure.
