Predictors of engagement in mothers receiving home visitation in the first year of service was examined. Early engagement was studied in three ways: (1) length of time active in the program during the first year of service (duration), (2) number of visits received (quantity), and (3) gaps in service between visits (consistency). Examined visits received in 515 first-time mothers in a Healthy Families America (HFA) program. Parameters of engagement were investigated, and predictors of engagement were identified using demographics and the Kempe Family Stress Inventory. Inclusive of the Assessment Visit, 31.8% of mothers disengaged prior to the first month of service. Remaining active in the program was associated with being Caucasian, and increased parenting risk (mental health/substance abuse history, low social support, increased stress). Most mothers had fewer home visits than prescribed. Gaps in prescribed service were common, with 89.4% of mothers experiencing gaps between visits of 1 month, and dropping to 16.4% having gaps of 2 months. In contrast to findings from clinic-based interventions, early engagement in home visitation is associated with lower levels of functioning and acute needs. These findings add to a growing body of literature suggesting that increased adversity promotes engagement in prevention programs in general, and home visitation programs in particular. To the extent that mothers who are actively engaged in home visitation are likely to have increased psychosocial needs, curricula may require modification and augmentation to address these needs and optimize program effectiveness. 相似文献

During the last twenty years the international protection ofgeographical indications (GIs) has experienced a worldwide resurgencespurred by both the greater need and the additional opportunitiesoffered by the global marketplace for the diversification ofagricultural products and foodstuffs. The Doha Ministerial Declarationlends support to developing countries that are seeking formsof knowledge less than high technology that they have the capacityto exploit. June 2005 saw the European Communities submit aradical proposal, designed to also meet the needs of developingcountries that would amend the Trade-Related Aspects of IntellectualProperty (TRIPS) Agreement in favour of a mandatory multilateralsystem of registration for all products. Yet, World Trade Organization(WTO) Members are as divided over their capacity to take advantageof GI protection no less than they are as to the means of regulation.To date, no ready solution to the further global harmonizationof GIs has been found. This paper examines the two major regulatorymodels advanced by the European Union and the United Statesof America for the protection of GIs. In the light of the DohaDevelopment Agenda, the authors argue in favour of an incrementalapproach that would allow developing countries the flexibilityto adjust additional protection in accordance with their levelof economic development. 相似文献

Reproductive genetic technologies are becoming more controversial as they become more ubiquitous. The opponents of these technologies are largely religious groups, a fact that leads to the question of why religious groups would be more opposed to these technologies than others. Since all of these technologies are justified by their ability to relieve suffering of some kind, it is hypothesized that the actively religious have a notion of suffering different from that of advocates for these technologies, and this different notion of suffering leads to opposition to the technologies. In this article I report on a qualitative interview study of the religiously active in the United States. I find that the religiously active do have views of suffering that are distinct from the medical consensus, and these views are related to people's conclusions about the advisability of reproductive genetic technologies. 相似文献
