Food aid: pitfalls and potential

This article poses the question of whether it is possible to use food aid to meet short-run needs while supporting and not undermining the achievement of long-term goals of self-reliance at the household and national levels. Often either some degree of self-reliance is sacrificed or people will suffer malnutrition. Food aid may be used to generate employment for low income families (food-for-work schemes), to reduce food prices during shortages by increasing the supply, and it can be delivered to target groups as a direct entitlement. What happens to food after delivery is important: often it goes to family members not targeted. Other factors (e.g. measles) affect nutritional status. Food aid must often continue for long periods to avoid nutritional regression. The stage in distribution at which food is used is important; e.g. a measles epidemic might affect the consumption but not the supply of food, or poor targeting might benefit families who do not need it. Complementary actions may improve conditions; for example, if food is sold, increasing income improves the situation. A problem with provision of food is depression of local prices, reducing incentives to produce food locally. Most food aid does not increase demand, and in fact if the effect is to change tastes away from local products demand may be reduced. The effect on demand depends on the type of aid scheme, the timing and duration, and the locality of the project. Most objectives are better achieved by the use of cash aid, which promotes rather than weakens local food producers' incentives, reduces transport and storage, redistributes food, does not affect taste, and adds income by contributing to local decentralized transport. Food aid is a good temporary intervention, but cash aid should be used in the long term.

The long and the short in migration decisions: an American case study

The author attempts an empirical analysis of the migration process. She starts with the assumption that migration involves an attempt to maximize long-term income and includes both micro-level aspects of individual's decisions to migrate and macro-level aspects, that is to say, aggregate migration flows. The model is used to analyze black internal migration in the United States between 1910 and 1970     

如何缩小CSR理想与现实的差距

近几年,欧美市场经历了一连串的公司丑闻、企业倒闭、股票大跌、经济危机等问题。旧有问题尚未解决之际,又有一些新的金融、环境和社会问题初露苗头。面对这种情况,我有所担忧,那就是人们对这些问题没有反思或者没有深度变革的需求。而事实上,目前,小到企业、政府、消费者,大到全球化和各种现代技术,甚至我们自我吹嘘的市场体系和资本主义本身都面临着严峻的挑战或者批评。     

The MISSCARE Survey-Turkish: psychometric properties and findings

One measure of the process of nursing care is missed nursing care, which refers to any aspect of required care that is omitted either in part or in whole or delayed. Little is understood about how the quality and processes of nursing care differs among countries around the world. The aims of this study were (a) to test the psychometric properties of the MISSCARE Survey-Turkish and (b) to compare the extent and type of missed care as well as reasons for missing care between Turkey and the United States. There was less missed care reported by Turkish nurses as compared to U.S. nurses (p < 0.0001). Turkey nurses identified more problems with inadequate staffing resources (p < 0.0001), materials resources (p < 0.0001), and communication/teamwork (p < 0.0001) as reasons for missed nursing care than did U.S. nurses. Missed nursing care is a critical problem that needs to be addressed in both countries.
