The Articles of Confederation, usually neglected by those studyingthe American founding, formed an important part of the backgroundto the 1787 Constitution. The Articles functioned as the firstnational constitution of the United States and, as such, reflectedAmerican political theory as it emerged during the Revolution.Equally important, a textual analysis reveals the extent towhich the 1787 Constitution was a logical extension of the Articlesof Confederation. Most of the Articles were incorporated inthe U.S. Constitution, and several key changes found in thelater document were present in embryo in the Articles of Confederation. 相似文献

The Downstream Benefits of Experimentation 总被引:1,自引:0,他引:1
The debate about the cost-effectiveness of randomized fieldexperimentation ignores one of the most important potentialuses of experimental data. This article defines and illustrates"downstream" experimental analysisthat is, analysis ofthe indirect effects of experimental interventions. We arguethat downstream analysis may be as valuable as conventionalanalysis, perhaps even more so in the case of laboratory experimentation. 相似文献

Behaviors developed in adolescence influence health later in life. The purpose of this study was to investigate the frequency of health care provider's discussion of health behaviors with overweight and non-overweight adolescents and identify demographic and health behaviors related to exercise, hours of television viewing, and weight issues associated with these discussions. A Cross sectional survey of urban adolescents was conducted. Trained interviewers administered surveys over a three month period in 2001 at an urban academic pediatric and adolescent clinic. The 252 adolescents surveyed had a mean age of 15 with 49% categorized as being at risk for overweight/overweight and 51% as normal weight using the CDC percentiles for BMI. While 16% of the adolescents reported that their physician or nurse discussed the amount of television they watched, rates of discussion related to exercise (58%), and weight (54%) were much higher. In multivariate analyses, health care provider discussions with adolescents regarding exercise were more common for overweight (O.R.=2.42, 95% C.I. [1.28–4.57]) and at risk for overweight (O.R.=1.98, 95% C.I. [1.03–3.81]) adolescents, whereas physician discussion of television viewing was not associated with weight. Discussions of weight were more common for female (O.R.=2.18, 95% C.I. [1.21–3.95]), African-American (O.R.=2.53, 95% C.I. [1.40–4.57]), and overweight (O.R.=3.92, 95% C.I. [1.97–7.81]) adolescents. Even after adjusting for weight, race and gender strongly influenced the frequency of discussions about weight in physician offices. Although health care providers frequently address weight and exercise with adolescents, more discussions related to sedentary behaviors such as television viewing may be warranted to address adolescent obesity.Received PhD in Epidemiology from University of California, San Diego.

Two implausible hypotheses implied by the directional theory of issue voting were tested using six Swedish national election studies, 1979–1994. The hypotheses that (a) centrists are indifferent toward parties, and that (b) people leaning slightly in one direction prefer an extremely intense party on the same side were not supported. However, alternative hypotheses from proximity theory were also not supported consistently. Self–placement on the left–right dimension and liking for a party form a logistic function. Party set and latitudes of acceptance, rejection, and noncommitment are concepts that may prove useful in understanding this relationship. 相似文献

Drawing on a purposive sample of 25 interviews supplemented by secondary source material, this comparative study explores the options available to elderly immigrants in two quite similar countries to achieve social security in their old age. The focus is the culturally determined perspectives and practices of aging Italian-born and Indian-born immigrants in the context of public and private sector social welfare policies and provisions in Australia and Canada. Government transfers, occupational superannuation, tax-deductible personal savings, housing, and formal and informal supports are discussed. What is important to the sense of social security of the older people and how well-off or disadvantaged they seem to be are among the questions raised. The design affords an opportunity to test the complex combination of cross-national and cross-cultural comparison. In the certainty that the income deficiencies of today's elderly immigrants cannot be remedied easily or quickly enough to benefit those affected, intervention strategies can be aimed at expanding ethno-specific community supports and quality residential care; such a direction is supported by assessment of service availability in relation to estimates of aging among particular foreign-born immigrant groups. Suggestions are made for future research at the levels of theory and application. 相似文献

Authors of two recent books, Smart Choices and The Win-Win-Solution, offer negotiation practitioners some new twists on how they can improve their decision-making processes. In the first book, Hammond, Keeney, and Raiffa present a five-part PrOACT system, which features: an assessment of the problem; determination of objectives; exploration of alternatives; comprehension of the consequences; and dealing with tradeoffs. The second book, by Brams and Taylor, outlines four settlement options that are available to decision makers, but advocates an adjusted winner approach. The authors have devised a system in which individuals' subjective assessments of particular items in dispute receive point totals, which can then be divided in an equitable manner. In effect, the authors show readers how to deal with the decisions they should make, and those they want to make. 相似文献

Retrospective analysis of autopsy findings in 60 infants who had been found unexpectedly dead in their cribs or beds in South Australia from 1994 to 1998 was undertaken to determine the diagnostic usefulness of individual stages in the postmortem investigation. Positive findings occurred in 2 of 43 scene examinations (3%), 2 of 60 external examinations (3%), 2 of 11 radiologic examinations (18%), 8 of 60 internal examinations (13%), 7 of 60 histologic examinations (12%), and 3 of 58 microbiologic examinations (5%). No positive findings were detected on toxicologic screening. Not every case underwent each diagnostic step. This gave alternative diagnoses to sudden infant death syndrome (SIDS) in 15 cases (25%). This study demonstrates an increase in the percentage of cases of unexpected infant death due to causes other than SIDS; it also shows the diagnostic yield of individual stages in the postmortem evaluation of such cases. Negative findings were important in giving validity to the diagnosis in the 45 cases that were ultimately designated as SIDS. 相似文献

An integrative, ecological model developed by Belsky (1980) implies that to understand child abuse researchers must examine factors at four levels: the individual, the family, the environment, and the culture. This study compared abusive and nonabusive parents at three of these four levels. At the individual level, abusers were found to have lower self-esteem than controls. Also, male abusers were likely to be relatively impulsive and hostile. At the level of the family, abusers described their children as more troublesome than control parents, but they did not perceive them as developmentally delayed. At the level of the environment, abusers identified more intense life stressors than nonabusers. Results of this investigation supported Belsky's argument that child abuse involved multiple factors and levels. 相似文献

Improvement in the ability of universities in the United States to transfer technology to the private sector is seen as a factor in strengthening American competitiveness. To better understand the university's role in this process, a survey of formal university programs in technology transfer was performed through personal interviews at four midwestern land-grant universities. There are six basic types of programs in place: technical assistance, affiliate, licensing, business development, incubators and research parks, and information networks. For purposes of classifying these programs, we used the model developed by Janis et al. (1) It was found that, of the six modes of technology transfer, two could be considered active, three semi-active and one passive. 相似文献
