General assistance among U.S. cities: A test of alternative hypotheses

Using 1980 census data, this study seeks to explain variations in race‐specific measures of general assistance among 109 U.S. cities. Four hypotheses (derived from developmental, conflict, and human ecological theories) are developed as potential explanations of welfare recipiency rates and payment levels. Three control variables (southness, population size, and education) are included in the analysis. Ordinary least squares (OLS) regression analysis reveals that for blacks, poverty, level of manufacturing employment (1970–1980), and southness are significant predictors of recipiency rates; whereas per capita revenue, segregation, southness, and population size are significant predictors of mean payment. For whites, poverty, percent white, and southness are significant predictors of welfare rates; whereas per capita revenue, percent white, segregation, and southness are significant predictors of mean payment. The analysis provides partial support for the need hypothesis in explaining General Assistance recipiency with respect to both races. It also provides moderate support for the segregation hypothesis and weak support for the functional transformation hypothesis in explaining General Assistance recipiency for blacks.     

Knowledge and Attitudes of University Health Service Clients about Genital Herpes: Implications for Patient Education and Counseling

Abstract

Genital herpes virus infection is an important target for health education efforts because of its apparently rising incidence in the college student population and because it can have potentially serious psychological as well as medical consequences. In order to better understand the health education and counseling needs of students, the present study surveyed knowledge and attitudes about genital herpes of 190 university students using a gynecology clinic and of 161 students using a general medical clinic. The students were found to have a high degree of familiarity with the disease, its cause, and mode of transmission, but tended to view the consequences of the disease as more severe than is actually warranted by the common medical complications. There was some degree of misinformation about prevention and treatment of the disease and some negative attitudes about patients suffering from it, but the survey respondents endorsed a high level of responsible behavior with regard to the disease and expressed some optimism about the possibility of adapting to it. These findings suggest specific misconceptions about genital herpes that might be amenable to a mass education approach. They also suggest the need for a counseling program that centers around reasonable reassurance and appropriately positive psychological and medical management for newly diagnosed patients.     

The Placement History Chart: A Tool for Understanding the Longitudinal Pattern of Foster Children's Placements

Despite growing concerns about foster placement instability, little information is available regarding the longitudinal patterns of placement histories among foster children. The purpose of the present study was to develop a charting system using child welfare records to facilitate a better understanding of longitudinal patterns of placement history for 117 foster children. The resulting Placement History Chart included all placements that occurred during the observed time period and accounted for various dimensions: number, length, type, and sequence of placements; timing of transitions; and total time in out-of-home care. The Placement History Chart is an effective tool for placing foster care experiences within a broader developmental context. As such, the Placement History Chart can be a valuable research tool for understanding various dimensions and variations of placement transitions among foster children by capturing sequences and cumulative risks over time. Furthermore, this chart can facilitate the development of intervention programs that are developmentally sensitive and effectively address particularly vulnerable subpopulations of foster children.     

The utilitarian contract: A generalization of Rawls' theory of justice

In a series of major papers culminating in A Theory of Justice, John Rawls constructs an alternative to utilitarianism by developing a social contract theory of moral and political philosophy. Unfortunately, Rawls formulates the two basic principles upon which the theory rests in such a way as to restrict (unduly) the contract theory's applicability (see Section I). In this paper we present a more general discussion of the theory of justice that avoids the problems of Rawls' formulation and yet retains the important idea of justice as fairness and the contractarian approach (Section II). Later it is argued that this more general theory constitutes a bridge between the pure utilitarian theories and the social contract doctrines (Sections V and VI). The theory's advantages are demonstrated by applying it to a problem discussed by Rawls, intergenerational equity, and comparing the two solutions (Section III). Further comparisons are made and inferences drawn in the concluding three sections.Without implicating them, we would like to thank James M. Buchanan and David Lyons for comments on an earlier draft of this paper.

Predicting distances using a linear model: the case of varietal distinctness

Differences between plant varieties are based on phenotypic observations, which are both space and time consuming. Moreover, the phenotypic data result from the combined effects of genotype and environment. On the contrary, molecular data are easier to obtain and give a direct access to the genotype. In order to save experimental trials and to concentrate efforts on the relevant comparisons between varieties, the relationship between phenotypic and genetic distances is studied. It appears that the classical genetic distances based on molecular data are not appropriate for predicting phenotypic distances. In the linear model framework, we define a new pseudo genetic distance, which is a prediction of the phenotypic one. The distribution of this distance given the pseudo genetic distance is established. Statistical properties of the predicted distance are derived when the parameters of the model are either given or estimated. We finally apply these results to distinguishing between 144 maize lines. This case study is very satisfactory because the use of anonymous molecular markers (RFLP) leads to saving 29% of the trials with an acceptable error risk. These results need to be confirmed on other varieties and species and would certainly be improved by using genes coding for phenotypic traits.
