"This study attempts to explain similarities and differences in the mortality experience of three population groups: Puerto Ricans on the island commonwealth, Puerto Rican born persons in New York City and Puerto Rican born persons in the rest of mainland United States. Mortality is much higher among Puerto Ricans in New York City than among those residing elsewhere. Much of the difference is due to excess mortality caused by cirrhosis of the liver and homicide. Puerto Rican born persons living on the mainland but outside New York City generally have low mortality, even when compared with U.S. whites."  相似文献

This article examines the current trends of proliferation of commercial gaming, especially in the United States, in the context of the third wave of legalization of gambling that has been experienced since the founding of the nation. The author looks at the historic foundations of the spread of casino-style gambling, and notes the types of casino gaming that have led the way in the current expansion. He also points out why it is reasonable to expect that this wave too may come crashing down, as general acceptance of wide-spread casino gaming in America may indeed be short-lived.Gambling and the Law® is a registered trademark of I.

This article reviews the literature on migration and HIV infections in the Mekong Region countries of Cambodia, China, Laos, Myanmar, Thailand, and Viet Nam. The HIV/AIDS situation is profiled in each country. The populations at risk include legal and undocumented cross-border migrants, internal migrants, sex workers, and mobile occupational persons, such as truck drivers, fishermen, seafarers, and cross-border traders. Currently, there is little regional cooperation on the issue of HIV among migrants. Prevalence is high in most of the region. Programs range from being very developed in Thailand to minimal in China. Recently, nongovernmental organizations have created innovative models. AIDSCAP studies have focused on river trade routes along the Thai-Lao border and fishing ports in Thailand and Cambodia. The Asian Research Center for Migration has researched fishermen in 6 countries; Burmese women in Thailand; migrants along the Thai-Myanmar borders; and the impact of transportation routes on the spread of HIV/AIDS along six main inter-country routes. Coordination of Action Research has engaged in research and action projects in 8 southeast Asian countries. The region would benefit from information exchanges about lessons learned and best practices. Field researchers could use better technical support. Regional strategies are useful for providing support from origin to destination.  相似文献

This paper illustrates the role of supervision in processing countertransference responses with might have disrupted the therapist's empathy with a patient who had killed her child. The clinical material demonstrates how the therapist's responses of initial denial and subsequent disgust and fear were dealt with in supervision. As a result, the treatment process led to genuine, albeit limited, therapeutic change in a patient with severe character pathology.This paper is developed from a presentation of the case of Mrs. Jay at Department of Psychiatry Grand Rounds, University of Cincinnati College of Medicine, on May 2, 1989.  相似文献

An analysis of the field of higher education reveals a surprisingly large number of classification errors within the (US) National Taxonomy of Exempt Entities database. Of the nearly 4,000 non-profit entities coded within the universe of institutions of higher education, we estimate that approximately 60 per cent were incorrectly included (Type II errors). Institutions incorrectly excluded from the higher education universe (Type I errors) represent roughly 10 per cent of the institutions coded correctly. These errors result primarily from assigning codes on the basis of the names of organisations (for example, College Park Towers is classified as a college, when it is in fact a housing complex for senior citizens) and from trying too hard to assign codes in ambiguous situations. The consequences can be significant for the users of these data, and we recommend raising bright warning flags while simultaneously enlisting the help of the entire non-profit sector in improving the classification coding process.The authors are with The Andrew W. Mellon Foundation. In addition to our colleagues on the staff of the Foundation, we wish to thank Helmut Anheier, Ted Bozovich, Harvey Dale, Virginia Hodgkinson, Stephen Noga and Christopher Toppe for helpful suggestions.  相似文献
