Over the past two decades states have significantly increased their use of competitive bidding to purchase health and social services from private agencies. Competitive contracting is thought to facilitate program administration, to reduce costs, and to increase the quality of delivered services. We evaluate these claims in light of Massachusetts' experience with competitive contracting for mental health care. We find that few of the expected benefits are achieved. In practice, supposedly competitive bidding systems often degenerate into administratively complicated negotiations between the state and private monopolies. This results in higher costs and lower quality of services. In light of this negative assessment, three strategies for reform are proposed and evaluated. 相似文献

In Garcia v. San Antonio Metropolitan Transit Authority (1985),a majority of the U.S. Supreme Court's justices did violenceto the principles of the U.S. Constitution by leaving the statesto take their Tenth Amendment complaints to the Congress. Inabdicating their proper constitutional role, the majority ofjustices ignored history, political realities, and constitutionalprinciple. The Constitution's institutional arrangements, ofwhich federalism is a key component, are an intrinsic part ofthe constitutional scheme by which government power is limitedand individual rights are protected. 相似文献

Abstract. The factors underlying patterns of partisan preference in Greece have been the subject of fairly little systematic analysis. This article uses data from a 1980 Euro-Barometer survey, the first to include a Greek sample, to outline the structure of the Greek partisan universe. A number of demographic variables – age, family income, education, occupation, sex, size of community, and household status – together with attitudinal variables regarding both foreign and domestic policy issues are tested as predictors of party identification. The multivariate statistical technique of discriminant analysis is used to measure the relative importance of these predictor variables in influencing the direction of party preferences. The findings show that attitudinal factors for the most part are more important than demographic traits. A stepwise analysis provides a rankordering of the strongest explanatory variables. The impact of recent political and historical developments on the party system in Greece is discussed. 相似文献

This research attempted to more adequately dimensionalize the study of affective family relations during adolescent pubertal maturation by employing a multivariate approach. Fifty-one families responded to an assessment battery consisting of a series of questionnaires designed to measure affective relations between parents and their adolescent children. Families were classified into prepubertal, transpubertal, or postpubertal groups according to their modal response on pubertal status criteria. A stepwise discriminant analysis was performed to identify measures that maximize between groups differences. Based on this analysis, a correct classification rate of 70% was achieved for all families. The two significant discriminant functions that emerged indicate that differences in family relationships are due to the transformation of mother-adolescent and father-adolescent relations. The pattern of results replicate those of other researchers and provide elaborations concerning the affective nature of family relations during adolescence.Received his Ph.D. in Life-span Developmental Psychology from West Virginia University in 1984.

The nonpartisan municipal ballot is one of several turn-of-the-century reforms intended to weaken political parties. Through its effects on individuals' political contexts and voting experiences, it might have contributed to the twentieth-century decline in public support for political parties. This paper tests this hypothesis with items available in the 1980 CPS presidential election survey augmented with a ballot form variable. There are no significant differences in measures of party support among residents of partisan and nonpartisan communities, and thus no measurable evidence that nonpartisan elections discouraged the public from supporting political parties.This is a revised version of a paper delivered at the XIII World Congress of the International Political Science Association, Paris, July 1985. 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.相似文献
