The contraceptive behavior of adolescent girls was viewed from a decision-making perspective. A semistructured interview protocol was used in interviewing 120 girls aged 12–19 in three clinics (Teen Family Planning, Prenatal, Pediatric Acute Care) at Michael Reese Hospital and Medical Center on (1) demographic in formation; (2) sexual and obstetric history; (3) contraceptive and sexual knowledge, attitudes, and practices; (4) environmental pressures; (5) personality factors; and (6) decision-making style. We found that the girls were generally poor contraceptors. They viewed the costs of contraception (in terms of safety) to be high; and they positively valued physical intimacy, opportunities for which come up unexpectedly and sporadically. These factors, along with their ambivalent views toward pregnancy and childbearing seemed to encourage their risk-taking behavior. Once pregnancy occurred, it was carried to term because of the strong internal and external pressures they felt to have and keep the baby. The peer-led intervention program that we are developing based on the survey findings will focus on (1) the teenagers' lack of accurate and complete knowledge about birth control and conception, (2) their limited sense of options concerning birth control and pregnancy outcomes, and (3) their poor understanding of and lack of insight into what motivates their behavior.This study is part of the investigation being conducted by the YADMAC (Young Adult and Adolescent Decision Making About Contraception) Project at Michael Reese Hospital and Medical Center, 2959 South Cottage Grove, Chicago, Illinois 60616.

An experimental study was conducted to test whether the version of the structured analytical method Analysis of Competing Hypotheses (ACH) taught by the Cabinet Office to the United Kingdom’s intelligence community provides effective mitigation of the cognitive biases of serial position effects and confirmation bias in an intelligence analysis. ACH had no statistically significant mitigative impact on the proportion of participants that exhibited serial position effects or confirmation bias, or the impact of confirmation bias on the analytical process. The most significant factor that influenced participants’ judgements of the credibility of information was the possibility of deception or dishonesty. 相似文献

Late in 1998, the United States acquired a new regime of tobaccocontrol engineered by the states' attorneys general. Nearlyall of them had filed lawsuits against the major cigarette manufacturers,allegedly with the aim of recouping Medicaid costs attributableto smoking. Despite latent differences of culture and interestin regard to tobacco control, all of the states eventually joinedin settlements with the industry that exacted large paymentsand restricted the industry's advertising and marketing practices.This article explains how it was possible for many differentpolities to agree on the settlement terms, and asks what thecase shows about the impact of federalism on tobacco policymaking.It concludes that tobacco policymaking in the 30 years priorto the lawsuits (19641994) was more consonant with constitutionalprinciples and not ineffective in achieving control. 相似文献

Guidelines for spending federal grants to the states for social services changed repeatedly between 1962 and 1975. The process of preparing guidelines changed, and so did their content. These changes are described and explained. Guidelines at all stages failed to provide intelligible and useful instructions to federal and state administrators. In part this was because the contextual supports that normally help to give effect to grant-in-aid guidelines—explicit antecedents in the law, and implicit understandings among administrators at different levels of the federal system—were lacking or seriously defective. Beyond that, in each of their different phases the guidelines proved untenable because of dysfunctions that may have been peculiar to the respective processes by which they were prepared.The trustees, officers, and other staff members of The Brookings Institution have no responsibility for the contents of this paper. 相似文献

Regulation of Cohabitation and Marriage in Canada 总被引:1,自引:0,他引:1
Martha Bailey 《Law & policy》2004,26(1):153-175
Marriage in Canada had lost much of its legal significance because of the extension of many of the incidents of marriage to unmarried cohabitants of the same or opposite sex. This process has resulted in large part from decisions of the Supreme Court of Canada that discrimination on the basis of sexual orientation or marital status is constitutionally impermissible. In a decision that seemed to many a surprising reversal of this trend, the Supreme Court of Canada in 2002 ruled that legislators could constitutionally exclude unmarried couples from family property laws. The effect of this decision has been to revive the legal significance of marriage. At the same time, courts have resurrected the social significance of marriage by accepting the argument of same-sex marriage advocates that a "separate but equal" civil union institution would not respect the constitutional guarantee of equality and by endorsing the constitutional right of same-sex couples to the symbolic value of marriage as a public and legal celebration of a relationship. Same-sex marriages may now be legally celebrated in three Canadian provinces, and the federal government has made a commitment to open up civil marriage to same-sex couples across the country. While some same-sex couples and unmarried cohabitants have fought for spousal or marital status, others have sought to avoid the burdens associated with spousal status. After the same-sex marriage debate is concluded, Canada will be ready to move on to consider whether all of the legal privileges and burdens now assigned to those in conjugal relationships, whether married, unmarried, same-sex or opposite-sex, can be justified. 相似文献

Evaluating international social-change networks: a conceptual framework for a participatory approach
International networks for social change are growing in number and influence. While they need to be able to assess the extent to which they achieve their purpose and determine ways in which to be more effective, conventional evaluation methods are not designed for such complex organisational forms, or for the diverse kinds of activity to which they are characteristically dedicated. Building on an earlier version of their paper, the authors present a set of principles and participatory approaches that are more appropriate to the task of evaluating such networks. 相似文献
