This paper presents the results of an ecological analysis of the relationship between infant mortality and economic status in a metropolitan aggregate comprised of seven of the larger cities in Ohio during the three years centering on the 1990 census. Using a summary income score derived for the census tract of mother's usual residence, the census tracts in the seven metropolitan centers were divided into broad income groupings and three-year average infant mortality rates were computed for each area, by age, sex, race, and selected causes of death. The most important conclusion to be drawn from the data is that in spite of some remarkable declines in overall levels of infant mortality during the past few decades, there continues to be a very clear and pronounced inverse association between income status and infant mortality. The general inverse association is observed for both sexes, for whites and nonwhites, and for all major causes of infant death. At the same time, the data reveal notable differences in the magnitude of the relationship by sex, and especially by age at death, race, and cause of death. Explanations of these differences are suggested, and a conclusion notes some of the difficulties encountered in developing programs aimed at closing the infant mortality gap between the richest and poorest segments of the society.This is an expanded version of a paper presented at the annual meetings of the Eastern Sociological Society in Baltimore, Maryland (March 17–20, 1994). 相似文献

DEVIATIONS FROM CONSTITUENT INTERESTS: THE ROLE OF LEGISLATIVE STRUCTURE AND POLITICAL PARTIES IN THE STATES 总被引:1,自引:0,他引:1
This paper investigates the determinants of state spending over 1960—1990. Recent empirical studies suggest that state government expenditure is greater than the electorate desires. Our main finding is that expenditure was positively related to the number of seats in a state's legislature. This is consistent with the hypothesis that logrolling leads representatives to spend more than their constituents would like. We also find that political parties do not have a pronounced effect on overall levels of expenditure, but do influence the composition of spending. In particular, Democratic control of state government is associated with higher levels of welfare spending. 相似文献

Data about health and educational services were collected from 187 families with young children (under two years) who have
chronic illnesses and disabilities. The purpose was to assess parents' satisfaction with services their families received
and to identify families' unmet service needs as well as the reasons for these unmet needs. Although families' ratings of
the adequacy of services are relatively high, 28% of the families report unmet service needs. The unmet needs most often reported
are occupational, physical, or speech therapy; respite care/child care; and special education. Lack of funding is the most
commonly given reason for unmet needs. Children with multiple impairments are at highest risk for unmet needs. Only 22% of
unmet needs reported at the initial interview have been met by the time of the six-month follow-up. Increased coordination
and monitoring of services across service sectors are indicated.

The Construction Industry Research and Information Association (CIRIA) has produced some guidelines for the assessment of the reliability of components and/or structures. The methods of analysis suggested by these guidelines are far from adequate and, in certain cases, contain some imperfections. In this paper, some of the weaknesses of the guidelines are identified. The shortcomings are mainly in the ease of calculations and the feasibility of the assumptions which are imposed. Three alternative methods aimed at tackling some of the weaknesses are introduced. A simulation study is used to compare these methods. 相似文献

L'article est base sur des donnees recueillies aupres des Indiens Cris des regions de Mistassini et de Waswanipi dans le Quebec. La these principale qui y est elaboree peut s'exprimer ainsi: la structure de role d'individus vivant dans des milieux en voie de developpement evoluera a partir d'un nombre restreint de roles traditionnels vers une structure plus complexe oil on observe une meilleure tenue de role. L'auteur elabore une echelle de modernisation: les individus les plus modernes se reconnaissent a leur scolarite, a leur milieu de residence, a leurs fonctions professionnelles et aux changements dans leurs attitudes et conceptions de l'avenir. En consequence, si on veut moderniser ces reserves, il faut susciter des changements a chacun de ces cinq niveaux de la realite sociale. This article takes data gathered on the Cree Indians in the Mistassini and Waswanipi areas of Quebec and analyses it in terms of their role structure. The principal thesis is that the role structure of people who are developing will change from a traditionally limited number of roles to a more complex structure with a higher degree of role performance. A scale of modernization is developed and is found to be associated with education, location of residence, occupational roles, and with changes in attitudes and orientation. Therefore, to bring about modernization would require changes in at least these five areas. 相似文献

In October, 1980, J. P. Stevens & Company ended a long, bitter labor-management battle by signing a contract with the Amalgamated
Clothing and Textile Workers Union (ACTWU). Labor hailed the victory as its long-delayed break-through for workers in the
traditionally nonunion, low-wage industries of the South. This paper assesses the importance of the Stevens/ACTWU settlement
for Stevens, the textile industry, and the changing Southern economy. When the ACTWU victory is examined in this light, it
becomes clear that the impact of the settlement is far more limited than is generally believed. 相似文献
