Two hundred and seventy-five college undergraduates coming from families of 2–7 children completed questionnaires about their relationships with their siblings. Aspects of intersibling communication, influence, and current and past affective relationships were investigated. The relationships reported were generally more positive than those revealed in other investigations of younger children. Presence of two parents in the home, size of the sibling group, and ordinal position of the respondent student had particular effects upon reported relationships. Furthermore, there were qualitative differences in the relationships between sibling pairs of different ordinal statuses. Results indicate that relationships between siblings have both complementary and reciprocal features, and caution against unidimensional characterizations.Teaches courses in child and adolescent development and assessment, and supervises school psychology trainees doing their internships. Received Ph.D. in psychology State University of New York at Albany. Main areas of research are sibling relationships, task attitudes and intrinsic motivation, and topics in adolescence. 相似文献

Sommaire: La Commission d'enquête sur les services de santé et les services sociaux, créée par le gouvernement du Québec en juin 1985, a remis son rapport au tout début de 1988. Cet article montre que la Commission a agi comme une espèce de metteur en scène, qui a proposé ce que devrait être la contribution des acteurs et la structuration du pouvoir dans les politiques publiques en matière de santé et de services sociaux. La Commission privilégie une alliance de type bureaucratique et une alliance de type socio-sanitaire, contre une alliance de type médical et une alliance de type managérial. Cette dernière semble la mieux placée actuellement pour structurer le pouvoir dans le système des services de santé et des services sociaux selon ses intérêts. Abstract: The Study Commission on Health and Social Services, created by the Quebec government in June 1985, submitted its report in early 1988. This article shows that the commission acted as a “packager,” specifying the recommended role of the parties involved and the power structure for public policy on health and social services. The commission favours a bureaucratic alliance covering the social/health area, rather than a medical/managerial alliance. The latter currently seems to be in the best position to structure the power in the health/social services system in accordance with its interests. 相似文献

Introduction
Longitudinal Analysis: An Introduction to the Special Issue 相似文献46.
Two of the three large countries on the North American continent—the United States and Canada—share a number of similarities that often make it difficult for the untrained observer to differentiate between the two nations. On the surface, the two are structured similarly as federal systems that, by definition, exhibit shared power between the national government and provincial or state political entities.Although there are other important social and economic characteristics of the two countries that help explain differences in policy processes and outcomes, it is the contention of this article that one gets the clearest sense of what Elazar has called thinking federal by utilizing an analytical approach that joins questions related to federalism with some conceptual frameworks of the public policy field. Two frameworks undergird the argument in this article—the Lowi typology of different types of policies and Deil Wright's typology of different models that describe the American inter-governmental system.In both countries, policies must be sensitive to the greater interdependencies between units of government as well as to linkages between policy areas. The mechanisms or instrumentalities for dealing with policy issues are intrinsically complex. It is also clear that the intergovernmental networks that exist in both the U.S. and Canada are composed of an array of actors. The differing political structures of the systems do impact the types of intergovernmental policies that have emerged in the two countries. The executive dominance so imbedded in Canadian governments has contributed to their ability to adopt and implement certain controversial redistributive policies, such as a national health insurance program. By contrast, the fragmentation of the U.S. system makes redistributive policies more difficult. 相似文献

Forensic analysis of glass samples was performed in different laboratories within the NITE-CRIME (Natural Isotopes and Trace Elements in Criminalistics and Environmental Forensics) European Network, using a variety of Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) systems. The main objective of the interlaboratory tests was to cross-validate the different combinations of laser ablation systems with different ICP-MS instruments. A first study using widely available samples, such as the NIST SRM 610 and NIST SRM 612 reference glasses, led to deviations in the determined concentrations for trace elements amongst the laboratories up to 60%. Extensive discussion among the laboratories and the production of new glass reference standards (FGS 1 and FGS 2) established an improved analytical protocol, which was tested on a well-characterized float glass sample (FG 10-1 from the BKA Wiesbaden collection). Subsequently, interlaboratory tests produced improved results for nearly all elements with a deviation of < 10%, demonstrating that LA-ICP-MS can deliver absolute quantitative measurements on major, minor and trace elements in float glass samples for forensic and other purposes. 相似文献

Efficient capillary electrophoretic STR analysis requires rapid, reproducible and robust separation of DNA fragments with reasonable capillary longevity--this is currently accomplished using proprietary commercial polymeric sieving matrices specifically developed for this separation. These matrices, while effective, are costly and do not provide adequate resolution of STR DNA fragments in capillaries with shorter effective separation lengths, increasing the time required to accomplish the separation and minimizing the potential extrapolation to other miniaturized platforms. As the forensic community looks toward next generation microchip technology as a means of processing casework more rapidly, new sieving polymers need to be evaluated for utilization in this platform. The research presented here describes the assessment of commercially-available polymeric sieving matrices for STR analysis, with consideration given to feasibility of incorporation into a microdevice. Polymer composition, molecular weight, and concentration were evaluated, along with an assessment of the effects of buffer composition, separation temperature, and capillary length. These variables were evaluated individually or collectively on the ability to resolve STR DNA fragments and the reproducibility of the separations and the results compared to a proprietary commercial product. A 600,000 Da MW poly(ethylene oxide) (PEO) solution at a 3% (w/v) concentration was determined to be the most suitable matrix for these separations. This polymer, in coated capillaries, provided highly robust and reproducible separations, with near baseline resolution of fragments having single base differences. Reductions in the temperature of the separation, from 60 degrees C to 40 degrees C, and the urea concentration of the buffer, from 7 M to 3.5 M, provided increased longevity of the PEO polymer for repeated separations. Comparison of this polymer with currently specified commercial products used for STR analysis showed that the optimized PEO matrix provided superior separations under all conditions tested. In addition, PEO could be utilized in shorter capillary systems, with a concurrent decrease in analysis time, highlighting its potential for use in shortened capillary or microdevice systems. 相似文献

Sommaire: Nos sociétés modernes font l'objet de débats très controversés autour du problème de I'accès à l'information gouvernementale. Une approche systémique permet entre aittres de prendre conscience des différents enjeux inhérents au contrôle de cette information. Elle expliqrie pourquoi certains Etats sont plus en-clins que d'autres à favoriser 1'accès à l'information gouvernementale. Dans cette approche, la société est perçue comme un système d'acteurs dont les trois principaux sont le gouvernement, les intermediaires et les différents publics, avec en plus les acteurs externes dans I'environnement. Ces acteurs sont soumis à des règles normatives ou pragniatiques. Leur pouvoir respectif de contrôle est loin d'être équivalent. Le pouvoir du gouvrnement sur les différentes dimensions de la communication le démarque fortement de ses compétiteurs. Certaines propriétés générales dri système, de caractère- plus macroscopique, sont ensuite dégagées, soit la tendance gÆné rale à l'amplification de I'information gouvernementale ainsi que la tendance a l'amplification des prohlémes contradictoires reliés au trop grand secret de l'information gouvernementale d'une part, et à la trop petite protection de l'information personnelle d'autre part. Le gouvernement québécois a maintenant legiféré dans ce domaine. mais la loi d'accès ne inodifie pas fondanientalement les propriétés generales du systeme ni le pouvoir prédominant du gouvernement sur les autres acteurs politiques. Abstract: In modern societies, the problem of access to government information has been the subject of passionate debates. The systemic approach offers, among other things, an awareness of the various stakes inherent in the control of this information. It explains why some countries are more favourably disposed toward easy access to government information. In this approach, society is perceived as a players' system, the three main actors being the government, the intermediaries and the public, with, in addition, outside actors. The actors are subjected to normative or pragmatic rules but their respective control is far from being of equal value. Through its power on the various dimensions of communications, the government is very much set apart from its competitors. Some general and more macroscopic characteristics of the system are then oAPred: on the one hand, the general tendency to exaggerate government information as well as the tendency to overstate the contradictory problems. 相似文献

A case of a four-month-old male infant is described who was found unresponsive at home and brought to the emergency room. He lived for four days. During his hospital admission he was diagnosed by radiography with a fracture of the third lumbar vertebra that was presumed abusive in nature. Autopsy examination failed to confirm a fracture. However, a defect in the development of the vertebral bodies was discovered. He was diagnosed with possible failure of the notochord to regress, a condition with no significant sequelae. The cause of death was certified as sudden infant death syndrome after full investigation, and all autopsy studies were negative. 相似文献
