In order to cooperate with voluntary screening programs aimed at the surveillance of the HIV epidemic in Finland, we have studied medicolegal autopsies for HIV antibodies since 1986 using an enzyme immunoassay on postmortem sera. The investigation covered 47.4% and 39.2%, respectively, of all deaths under the age of 65 years in the metropolitan areas of Helsinki and Turku--two cities on the densely populated southern coast of Finland from which most HIV infections have thus far been detected. Nine HIV-positive cases (0.12%) were detected among the 7305 medicolegal autopsies tested in 1986 to 1990. This figure is higher than the prevalence of 0.01 to 0.03% in voluntary screening programs for the general population would suggest. Seven of our cases had previously tested positive, and two were previously unknown cases, indicating that people at high risk are clustered in the medicolegal autopsy series. Of the six cases in an early stage of infection, three committed suicide suggesting the importance of HIV-screening in suicide cases in tracing symptomless HIV carriers. Five of the cases were detected in 1990, a year when the number of new HIV infections had more than doubled compared to the previous two years. This suggests that testing of medicolegal autopsies as surrogate tests for the population gives useful information even in low-prevalence areas like Finland. Such testing has none of the ethical problems of many other back-up surveys, and may be particularly sensitive to early changes in epidemiology.  相似文献

Historically, small businesses have been the innovation engine of the United States, with significantly more than half of the new technologies and products coming from small enterprises. In 1992, there were more than 21 million small businesses with fewer than 500 employees each in the United States, including 4.5 million small corporations, 1.6 million partnerships, and 15.1 million sole proprietorships. Although most small businesses have considerably fewer than 100 employees, they employ more than half the private U.S. work force, contribute more than half of all sales in the country, and are responsible for over half of the private sector's products. From 1976 to 1990, small firms also generated 65% of the net new jobs. From 1988 to 1990, all of the net new jobs in the U.S. economy were created by small firms. Indeed, small business is really big business in the United States.  相似文献

The present study investigated the extent to which psychosocial development through the first five stages of Erik Erikson's theory of personality development is associated with Diagnostic and Statistical Manual (third edition, revised; DSM-III-R) Axis II personality disorder symptomatology in a late adolescent sample of undergraduate students. The Inventory of Psychosocial Development (IPD) and the Personality Diagnostic Questionnaire—Revised (PDQ-R) were administered to a mixed-sex sample of 106 undergraduate students. The results of this research were that IPD scores assessing negative resolutions of the first five Eriksonian developmental stages consistently predicted scores on the PDQ-R composite scale and the PDQ-R impairment/distress index—both measures of overall personality disorder symptomatology. The IPD subscales varied substantially in the extent to which they predicted scores on the 13 PDQ-R subscales that assess symptoms of specific DSM-III-R personality disorders—ranging from the trust vs. mistrust subscale, which predicted scores on 12 of the 13 PDQ-R subscales, to the initiative vs. guilt subscale, which predicted scores on only 6 of the 13 PDQ-R subscales. Implications of these findings for our understanding of the relationship between psychosocial development and psychopathology are discussed in the context of previous research in this area, and suggestions for future research are offered.Received Ph.D. from Temple University. Research interests include personality disorders, depression, and life events.  相似文献

In a free market world economy now characterized by a strong trend towards integrated economic areas dominated by North America, Western Europe and the Pacific, effective cooperation is the key to sustained success. Mr. Lautenberg is a diplomat, whose career has been strongly oriented on bilateral and multilateral economic matters (Poland, FRG; GATT, EFTA, CSCE). Between 1970 and 1974, Mr. Lautenberg, who holds a degree in political sciences from the University of Lausanne, led various research programs at the General Staff of the Department of Defense.  相似文献

This study uses a structured vignette procedure to assess competency to make treatment decisions in two groups of adolescents, one at risk for institutional placement and the other a matched community sample. Scores on Factual Understanding (the ability to recall facts), Inferential Understanding (the ability to make inferences about those facts), and Reasoning (the ability to weigh risks and benefits of various treatment options and to make choices based on that reasoning) were compared. Results showed that while at-risk adolescents and their community, counterparts did not differ in their factual and inferential understanding abilities, the at-risk adolescents did significantly less well than the community adolescents in reasoning. This difference could not be fully explained by differences in verbal IQ. Girls, no matter what their risk status, scored higher than boys on the Reasoning scale. Implications for legal policies concerning adolescents are discussed.  相似文献

Compulsory competitive tendering (CCT) has been an important instrument of Conservative government economic policy since 1979. Its effectiveness in generating cost-effective services depends on competition to supply the service in question.
The NHS domestic market is large and, prior to the introduction of CCT, promised to be profitable for contractors. Many contract cleaners with office cleaning experience entered. In the event the costs of entry were heavy, and the profit margins of established firms were reduced. When contracts have been awarded to firms, they tended to be to those with a track record. Many firms therefore withdrew; and the few that remained have profit margins in the NHS little different from those found elsewhere. Of more than by firms with a serious interest in entry, probably no more than a handful can have come out of the experience in net profit in the first seven years.
The experience of CCT in the market for NHS domestic services has shown that a degree of competition in the market can be achieved, arguably because of the presence of direct service organizations. Competition for this market, on the other hand, can be limited by the high costs of entry.  相似文献
