Previous studies have compared contraceptive users with nonusers, and pregnant teens with nonpregnant ones. This paper reports the findings of a study of a sample of 119 women aged 21 and under who visited the Young Adult Clinic at Columbia-Presbyterian Medical Center in New York City during 1981. All of these women had been sexually active for a year or longer, but had never been pregnant. The expectation that such a sample would include mainly consistent users of contraception was unwarranted; within this special population were found young women who had never used contraception or who had only been sporadic users, as well as the consistent users. Moreover, there are many more similarities than differences among these groups, and their stated motivations for not becoming pregnant are the same. The consistent contraceptors were more likely to live with their mothers, to have mothers who worked, to indicate that their parents would help them have an abortion, and to indicate they would have an abortion should they become pregnant. The similarities between these young women are very important for programs, which often rely heavily on stated motivation or even on a clinic visit as evidence that a young woman intends to use a birth control method. There is nothing here to support this simple view. Instead the notion is substantiated that many adolescents may lack cognitive consistency on this subject or may lack the future orientation to be effective contraceptive users. 相似文献

In June 2002, the UN Theme Group on HIV/AIDS in China published a comprehensive situation analysis and needs assessment of the HIV/AIDS epidemic in the People's Republic of China (PRC). The report, entitled "HIV/AIDS: China's Titanic Peril", also describes and analyzes current HIV/AIDS legislation and policies. It notes that "laws and regulations that are based on fear and prejudice have contributed to fuelling the epidemic instead of curbing it." The report observes that the targets and goals established in China's five-year Plan of Action (2001-2005) are not consistent with the commitments endorsed in June 2001 at the United Nations General Assembly Special Session on HIV/AIDS. It states that the Plan "continues to present HIV/AIDS as a medical problem, and fails to understand the epidemic as a broader development issue." Even where laws could assist, enforcement remains a huge challenge. For example, in 1998 the National People's Congress passed a law prohibiting commercial blood donations for medical purposes. Nonetheless, the illicit and unregulated blood trade, which has rapidly accelerated the spread of HIV infection in China, has continued. When the alarm was sounded by Dr. Wan Yanhai, coordinator of the AIZHI (AIDS) Action Project, the government response was to arrest him. In the following article, Nick Young, editor of China Development Brief, reviews the findings of three studies commissioned by the United Nations Development Programme (UNDP) on the role of the law in response to HIV/AIDS. 相似文献

The authors describe three accidental deaths resulting from occupational hazards involving environmental gas alterations. One involved the displacement of oxygen caused by leakage of liquid nitrogen during the installation of a magnetic resonance imaging system. Two involved elevated environmental carbon dioxide concentrations: dry ice sublimation in a walk-in refrigerator in a research laboratory, and activation of a carbon dioxide fire alarm-extinguisher system by a woman locked in a bank vault. The autopsy findings, scene investigations, and certifications of these deaths, as related to the mechanisms of death, are discussed. 相似文献

Child death due to repeated episodes of physical assault or neglect has been termed the child abuse-maltreatment syndrome (CAMS). We characterized the injuries in a series of fatally abused or maltreated child to delineate objective diagnostic criteria for the CAMS for use by clinicians and pathologists. All deaths (age <17 years) investigated by the Office of the Chief Coroner for Ontario, Canada during the time period 1990-1995 were reviewed. Cases of CAMS were defined as death due to lethal recent injury or malnutrition in the presence of significant old (healing or healed) injuries indicative of repeated episode of inflicted trauma. The nature and frequency of the various injuries was determined. The frequency of the shaken baby syndrome, and the types and frequency of ano-genital injuries were also studied. Twenty-one cases of fatal CAMS were found in the study period. Most cases had significant recent head injury with intra-cranial hemorrhage (71%). Other significant recent injuries commonly observed included blunt injuries of the skin and soft tissues (67%), blunt abdominal trauma with visceral injuries (14%), and fractures (18%). Eight cases (38%) fulfilled accepted criteria for the shaken baby syndrome. Many children with fatal head injuries had evidence of older head trauma (38% of all cases). A significant minority of cases had evidence of malnutrition due to neglect (10%) or ongoing ano-genital injuries (10%). Most cases of child homicides due to repeated episodes of abuse or maltreatment involve head trauma including shaken baby syndrome. Fractures of long bone and ribs, the classical markers of child abuse, were relatively infrequent compared with head injury. A proportion of cases had ano-genital injuries due to repeated sexual abuse or punitive maltreatment. All clinicians and pathologists must recognize the wide spectrum of injuries in child abuse to ultimate protect the victim or other children in an at-risk situation. 相似文献

Abramson and Inglehart find a significant trend toward postmaterialist values in Western Europe, which they argue is largely driven by the gradual processes of generational replacement. Clarke, Dutt, and Rapkin argue that this trend is a methodological artifact of the wording of Inglehart's four-item measure of materialist/ postmaterialist values. They claim that because this battery does not include a question about unemployment, in periods of high unemployment respondents tend to choose postmaterialist goals. The long-term trend toward postmaterialism in Western Europe, they argue, results from rising levels of unemployment during the past two decades. Abramson and Inglehart point out that increases in inflation have a short-term impact on decreasing postmaterialism, but maintain that the positive relationship between unemployment and postmaterialism is spurious. As this analysis shows, Clarke, Dutt, and Rapkin find a positive relationship between unemployment and postmaterialism by building a model that has little theoretical justification and that is not robust to changes in specification. As this analysis demonstrates, unemployment is actually linked with support for materialist goals, and the trend toward post-materialism is robust in the face of alternative time frames, models, and specifications. The weight of the evidence demonstrates that the long-term trend toward postmaterialism in Western Europe is driven by generational replacement. 相似文献

This article reports on a highly unusual experiment in racial and economic integration, the Gautreaux program. This program helps black families who are either current or former residents of public housing move into subsidized housing in Chicago and its suburbs. Surveying a random sample of 332 participants, we find that suburban movers are significantly more likely to have a job post-move than city movers, even among those who had never had a job before moving. Multivariate analysis shows that these differences are significant even after controlling for respondents' previous work history, human capital, and personal characteristics. These results suggest that low-income urban blacks experience significant gains in employment by moving to middle-class suburbs. Thus, housing assistance may be an effective alternative to traditional welfare-to-work programs. 相似文献
