This study examines the impact of mandatory seat belt laws on fatal and incapacitating injury rates in the states. Annual data for all 50 states for the period 1975-1991 are used. Pooled time series analysis is employed. The general conclusion that emerges from this analysis is that seat belt laws significantly impact state fatal injury rates. Primary enforcement and all-seat coverage provisions appear to be particularly effective in reducing fatality rates. 相似文献

Sensitive research issues call for anonymous questionnaires. This makes accurately matching pretests with posttests difficult or impossible. Various subject-generated coding schemes have been developed, but their accuracy has been unknown. This anonymous study, with 745 students, used subject-generated coding to match pretests with posttests. The matching was verified for accuracy with the use of a collateral, anonymous, sticker identification system. The coding system was able to accurately match 75.2% of all the pretest-posttest pairs. An additional 22.1% of the pairs were left unmatched and only 2.7% were matched incorrectly. Subject-generated coding systems can be very effective where confidentiality is important to protect. 相似文献

"In the Netherlands, the social meaning of both marriage and cohabitation has changed. Cohabitation started as an alternative way of living, developed into a temporary phase before marriage, and finally became a strategy for moving into a union gradually....This article addresses the question whether or not individual past and current life-course experiences become increasingly important in explaining the differentiation of entry into marriage across female birth cohorts, and yet become decreasingly important in explaining the differentiation of entry into cohabitation across female birth cohorts. This question is examined using a non-proportional hazard model. Empirical evidence supports this hypothesis strongly, in that both past determinants such as family size or religion and current life-course determinants such as work or education change in their impact on cohabitation and marriage across birth cohorts." 相似文献

This study is based on interviews with a sample of 400 single women aged 18-25 years from the Fante ethnic group in Cape Coast, Ghana, in 1991, and on focus groups. This case study illustrates the importance of economic and living arrangement support expected from partners in premarital relationships. Support may be for living and maintenance ('chopmoney', provisions, household items, and rent); for financial security (provision of capital); and for clothing and hairdressing. Women did not always require economic support in premarital relationships. Women expect boyfriends to provide 'chopmoney' (money for food and general upkeep) and contribute some money for the rent. Only 36% of sexually active women expected their boyfriends to supply food provisions. Premarital sexual relationships are used to obtain start-up capital. The author refers to evidence that senior government officials engaged in sexual transactions with clients before loans and credit facilities were offered. 87% of sexually experienced women expected their partners to pay for at least part of clothing expenses. The study revealed that there was considerable disparity between women's expectations and actual receipt of economic support. 56% desired, but only 36% received, 'chopmoney' in full. 40% expected their partners to pay for household furnishings in full, while only 10% did so. 55% expected capital, but only 15% received it. The three most frequently received benefits in full were hair dressing, shoes, and dresses. Men provided most non-negotiable items as a means of "boosting their egos." Many young women rely on the support of men in order to improve their status. Ghanaian men control financial resources and economic power. Mothers of adolescent daughters encourage premarital sexual behavior. Prostitution is considered different from sexual exchange relationships. It is argued that gender inequalities and domestic abuse are perpetuated through sexual exchange relationships. 相似文献

"A study of 27 [developed] nations indicated that divorce rates rose in 25 of the nations from 1950 to 1985 while marriage rates declined in 22 of the nations. Nations with higher divorce rates in 1950 had steeper increases in the divorce rate subsequently, supporting a critical-mass hypothesis." 相似文献

The mandate for health care organizations to be accountable for quality, as well as price, is now unavoidable. The Joint Commission's ORYX project is requiring every hospital to measure clinical outcomes of a majority of its patients within the next three years. This mandate can be met best with systems of clinical outcomes measurement that provide valid, reliable risk adjustment; yield meaningful information about many different diseases and procedures; and measure more than mortality or cost--all using primarily billing data. New outcomes measurement tools with all of these capabilities are available and have already enabled quality improvement in dozens of hospitals across the U.S. 相似文献

The glass ceiling is a form of organizational bias and discrimination that prevents qualified professionals from achieving positions of top governance and leadership. This article examines glass ceiling barriers that keep physicians from the upper reaches of management. While these factors apply mainly to women and minority physicians in academia, and are attributable to sexual harassment and discrimination, physicians as a class are frequently denied executive management positions. Such denial results from inadequate preparation for a career in health care administration. Important issues in the professional development of physician executives include mentoring, training and education, administrative experience, and cultural and personality factors. All of those must be considered when making the transition from medicine to management. 相似文献

As the medical delivery system undergoes fundamental change, there is a growing pressure on hospitals to form networks with physicians. The prime motivation for these entities is to preserve market share and fill beds. There is likewise intense pressure on physicians to join them, even if these networks do not serve their best interests, or the goal of fostering physician-centered practice. A transformation is under way, however, that may well place doctors again in the central role of guiding the new modes of medical practice in the United States. 相似文献
