Sexual decision making, perceptions of responsibility for birth control and pregnancy, and knowledge of contraception and the consequences of teenage pregnancy were assessed among 251 high-risk seventh- and eighth-grade black, inner-city adolescents to determine these young peoples' need for information. Survey results indicated that these adolescents were aware of contraceptive methods, but lacked practical information about requirements for obtaining them or method effectiveness. Many students were uninformed about the circumstances under which pregnancy can occur. Males indicated a willingness to have intercourse, regardless of the contraceptives used, if any, and believed responsibility for use of a birth control method belonged to females. Females believed themselves to be responsible for contraceptive utilization and preferred intercourse with adequate protection. Both genders endorsed the notion of mutual responsibility for an unplanned pregnancy and related decisions. Implications for school-based family life education programs for young adolescents are discussed.This research was supported by grants from the Illinois Department of Children and Family Services and the Pittway Charitable Trust, to the Center for Health Services and Policy Research of Northwestern University; the project was administered by the Ounce of Prevention Fund. Portions of this paper were presented at the 112th annual meeting of the American Public Health Association at Anaheim, California, November 1984. Conclusions or opinions expressed in this article are those of the authors and do not necessarily reflect the views of the Center for Population Options, Northwestern University, or the State University of New York at Buffalo.Received Ph.D. from Loyola University of Chicago.

Although behavioral scholars have devoted much time and energy to attempting to explain decision making on the U.S. Supreme Court, they have virtually ignored the unanimous decision. We investigated the Vinson, Warren, and Burger Courts and discovered that the liberal outcome was more successful in the unanimous cases whether those cases involve civil liberties or economic liberalism and whether they were decisions to reverse or decisions to affirm. We also ascertained that the ideological position that tended to win in the unanimous reverse cases was related to the ideological position that tended to win in the nonunanimous reverse cases, but that no such relationship was present in the two kinds of affirm cases. These two findings are in conformity with a psychometric model, which posits that the relative position of judicial attitudes and case stimuli determines the vote on the U.S. Supreme Court.  相似文献

In an attempt to delay hatching without affecting their viability, the eggs ofLatheticus oryzae W. were subjected to cold treatment at 5° for varying periods and at different stages of their development. A small dose of 0.5 krad of gamma radiation was also given at each of those temperature treatments. Most of the eggs hatched at 30° following low-temperature exposures of 1 and 2 days. There was a significant decrease in hatch as the exposure period increased further (P<0.05). An egg exposure to 5° also led to an increase in egg period and the increase was nearly equal to the period of cold exposure. Radiation did not alter the situation.
Zusammenfassung Kühllagerung ist eine der gebr?uchlichsten Methoden für die Aufbewahrung von Insekteneiern. Um die optimalen Bedingungen für eine Vorratshaltung zu bestimmen, wurden 0–1 d alte Eier vonL. oryzae Temperaturen von 5° w?hrend 1–7 d ausgesetzt, nachdem sie verschieden lange bei 30° gehalten waren. Eine kleine Dosis von 0.5 krad Gammabestrahlung wurde bei jeder Temperaturbehandlung ebenfalls gegeben. Alle Eiproben wurden nach den verschiedenen K?ltebehandlungen in 30° zurückgebracht und die Wirkung auf Schlüpfprozentsatz und Eidauer bestimmt. Die Eidauer nahm zu, wenn die Eier bei 5° gehalten wurden, was anzeigt, da? die Embryogenese bei 5° unterdrückt wurde. Die Lebensf?higkeit der Eier wurde nicht beeintr?chtigt bei einer 5°-Einwirkungsdauer von 2 d, nahm aber bei weiterer Verl?ngerung der Expositionsdauer ab. Nur etwa 37% der Eier schlüpften (44,1% der Kontrolleier) nach 7-t?giger K?ltebehandlung. Bestrahlung beeinflu?te weder das Schlüpfen noch die Entwicklungsdauer.

The current study examined the nature and style of mother-adolescent conversations, how these conversations differ by subject matter, and dyadic and individual differences. Thirty-one mother-adolescent dyads (17 boys, 14 girls) with a child between the ages of 11 and 14 had a nonstructured conversation, and conversations about conflict and sexuality. They also completed questionnaires on beliefs about acquired immunodeficiency syndrome (AIDS). Conversations were measured for turn taking, total number of words, and conversational dominance, as well as nonverbal measures of affiliation, shame, and contempt. Conversations about sexuality involved less turn taking, fewer words, and more mother dominance than nonstructured conversations. Conversations about conflicts involved less turn taking but more words than nonstructured conversations. Some gender and age differences were found. More interactive conflict conversations contained higher levels of affiliation, and lower levels of child shame than conversations with fewer turns or higher mother dominance. In addition, children in more interactive dyads possessed a larger percentage of their mother's AIDS knowledge, and worried about AIDS a moderate amount.This research was supported by National Institutes of Child Health and Human Development Grant No. HD27035.Received M.A. from UCLA.

This paper is an analysis of two rational choice theories of elections. Anthony Downs and Stanley Kelley's theories yield complementary interpretations of the 1984 U. S. election. Reagan's victory was based on both prospective and retrospective judgments as well as on candidate and policy considerations. Reagan won that element of an incumbent's reelection that is a referendum on his performance as president. However, people also voted on the basis of domestic and foreign policy preferences for the second term. On these issues voters preferred Mondale as much as Reagan. Reagan's victory owed remarkably little to his conservative agenda and to a warm regard for his personal qualities as a leader. His landslide was deceptive. The two Reagan victories were among the weakest of the six landslides of the postwar period by Kelley's test of decisiveness. The Reagan elections have not set the United States on the course of a long-term conservative agenda in either domestic or foreign affairs.  相似文献

The combination of a tradition of arbitrary royal government and popular intolerance, with the existence of extensive, unitary and highly centralized institutions of government, and with the dominance of government by a single, reformist party for more than a half century would seem a potent recipe for governmental abuse of individual and minority group rights. That is especially true in the absence of the formal constitutional safeguards used to preserve rights elsewhere Yet the Nordic democracies have in fact proved exemplary in protecting civil liberties Why? This article challenges the view that Nordic political societies are consensual historically or by nature, and it describes the limited traditional institutional checks on abuse of individual and minority rights by government Instead it finds the basis for the Nordic democracies' excellent record in civil liberties in the combination of (1) the development of new, non-traditional institutional checks on government. (2) the use of direct democracy as a check on parliamentary majorities. (3) the pervasive use of corporatist channels encompassing the major oppositional interest groups to draft and implement legislation, and (4) the effective constraints placed on decisions by parliamentary majorities by the pattern of fierce partisanship in the finely balanced parliamentary party constellation These protections for individual and minority liberties arise primarily from the assumption that basic conflicts of interest are a fact of political life and that they should be institutionalized.  相似文献

There is no shortage of warnings concerning the hazards of excessive ambition in consciously-pursued public policy. In the light of these cautions, this paper considers the appropriate ambitions for policy design. The critics have missed the target. There is no need to fear ambition in policy design, provided that openness in communications about policy is secured.  相似文献
