This article is based on findings from semi-structured interviews and discussions among "chilimba" groups in Zambia. Chilimba groups are primarily women's groups that engage in credit and savings programs. Group membership ranges from 4 to 20 members. The women agree on a fixed, regular cash contribution that is given in turn to each member in a specified order. Market groups tend to be larger and contributions of about a dollar are made daily. Smaller groups tend to make larger, but less frequent contributions. Default is rare, as the commitment is taken very seriously. New members are added at the end of the rotation. Loans can be used for domestic or business use. Chilimba groups are evidence that very poor people desire savings. Chilimba brings together people with similar financial needs and resources. Chilimba does not require formal, written procedures or formal institutional frameworks. Chilimba is not a remedy for reducing overall poverty. It is appropriate only for people with some regular source of income. It does not serve as a safety net in emergencies. Long-term loans are not possible. A limitation is its openness and lack of structure that permit potential abuse. It is a livelihood strategy for women, but benefits could be gained from including men. It is urged that groups consider whether the position of the poor is being enhanced or undermined. Different models need to be tested. Members themselves must decide on the type and phasing of activities.  相似文献

Recent medical studies have indicated that synthesized human growth hormone (hGH) may cosmetically enhance short, but otherwise perfectly healthy, individuals by adding inches to their final predicted height. In this note, Curtis Kin examines the legal and ethical implications of such a discovery, arguing that nontherapeutic hGH treatment is likely the first of many biotechnology and gene therapy enhancements that may be available to the public in a "genetic supermarket" of enhancement products. Mr. Kin finds that the current regulatory framework for biotechnology and gene therapy inadequately regulates unapproved uses of hGH and fails to address properly its implications for a genetic "race to perfection." He proposes changes to the current regulatory framework that will enforce a strict distinction between therapeutic and enhancement applications of biotechnology and gene therapy. These changes in the law, Mr. Kin reasons, will help to solve the social and ethical problems posed by these emerging developments in technology.  相似文献
