Social compromise and social metrics 总被引:1,自引:0,他引:1
In the context of constitutional design, a committee of citizens' representatives proposes (social choice) axioms. The outcome should not necessarily be the aggregation rule, or rules, satisfying each of the axioms. Alternative procedures are recommended for aggregating a set of axioms into a single summary axiom. The summary axiom generates a single social decision function when a social metric is applied. 相似文献

A health-oriented interactional model of adolescent change in times of transition is presented. Four factors are discussed: 1. the effect of individuals and the environments on each other; 2. the interactive flow between regression and growth, vulnerabilites and competencies, crisis and equilibrium; and 3. the interactive effects of psychological, social and physical factors. A social work assessment and intervention model is built on this framework.Ms. Lammert is an Associate Professor, National Catholic School of Social Service, a consultant to the American Digestive Disease Society and to the Christ Child Society School Counseling Program and in private practice. 相似文献

High rates of psychiatric symptoms have been reported in pathological gamblers. This study of psychiatric comorbidity in pathological gamblers is the first to use structured psychiatric interviews assessing DSM-III-R Axis I and II disorders. The Structured Clinical Interview for DSM III-R (SCID-P, SCID-II) was administered to 40 (25 male, 15 male) pathological gamblers seeking outpatient treatment in Minnesota for gambling, and 64 (41 male, 23 female) controls. High lifetime rates of Axis I (92%) but not Axis II (25%) psychopathology were found in pathological gamblers as compared to controls. No differences between male and female gamblers were found in rates of affective, substance use or personality disorders. Females had higher rates of anxiety disorders and histories of physical/sexual abuse. Possible associations between psychiatric disorders and pathological gambling are discussed along with gambler typologies and implications for future research.The authors wish to gratefully acknowledge the assistance of: Gary Christenson, M.D., Carol Peterson, Ph.D., William Meller, M.D., Thomas Mackenzie, M.D. 相似文献

A system of predictors for estimating a finite population variance is defined and shown to be asymptotically design-unbiased (ADU) and asymptotically design-consistent (ADC) under probability sampling. An asymptotic mean squared error (MSE) of a generalized regression-type predictor, generated from the system, is obtained. The suggested predictor attains the minimum expected variance of any design-unbiased estimator when the superpopulation model is correct. The generalized regression-type predictor and the predictor suggested by Mukhopadhyay (1990) are compared. 相似文献

The impression of journalists and social critics in the 1950’s that post-war suburbia was uniformly middle-class has been generally rejected by social scientists, but there is a persisting belief in a high degree of residential segregation by social level in suburbia and in a high degree of socio-economic homogeneity within suburban neighborhoods. A comparison of eight central cities with their suburban zones in 1950 and in 1960 revealed, for both dates, (a) small differences in occupational distributions between the central cities and the suburban zones and (b) generally higher Index of Residential Dissimilarity values for pairs of occupational groups in the central cities. These findings indicate that suburban neighborhoods, at least in the eight suburban zones studied, were little, if any, more occupationally homogeneous than the central city neighborhoods. This suggests that the belief in homogeneous suburban neighborhoods should be added to the growing list of discredited “myths of suburbia. ” 相似文献

Abstract In the Netherlands, as in other countries, substantial regional differences in the birth rate have always been the rule rather than the exception. Of course, differences in crude birth rates may be attributed to a number of possible reasons, not all of them of primary demographic interest. For instance, according to the census of 31st December 1899, the number of women per 1,000 men in the province of Drenthe was only 924; in the province of Zuidholland the corresponding number was 1,073. It is clear that, ceteris paribus, the crude birth rate in Zuidholland would be about 7% higher than in Drenthe at that time. In such a case, the difference could reflect differences in economic development or job opportunities, factors not devoid of demographic significance, but only indirectly so. 相似文献
