Correspondence to Andrew Bunyan, 20 Cranmer Drive, Meadow Gardens, Syston, Leicester LE7 8HY. Summary This study describes the implementation of a behavioural approachto treatment in a family with a four year old child at seriousrisk of a buse, presenting problems of defiance, demanding,aggression, destructiveness and sleep irregularity. Followinga comprehensive assessment, positive reinforcement, extinctionprocedures and time out were systematically applied throughthe use of a home-based triadic model of intervention. Initialresults (and a follow-up study) have indicated a significantimprovement in the child's behaviour. 相似文献

This paper presents the results of a natural experiment conducted at a U.S. high‐tech manufacturer. The experiment had as its treatment the adoption, at a single point in time, of a comprehensive enterprise information system throughout the functional groups charged with customer order fulfillment. This information technology (it) adoption was not accompanied by substantial contemporaneous business process changes. Immediately after adoption, lead time and on‐time delivery performance suffered, causing a “performance dip” similar to those observed after the introduction of capital equipment onto shop floors. Lead times and on‐time delivery percentages then improved along a learning curve. After several months, performance in these areas improved significantly relative to preadoption levels. These observed performance patterns could not be well explained by rival causal factors such as order, production, and inventory volumes; head count; and new product introductions. Thus, this longitudinal research presents initial evidence of a causal link between IT adoption and subsequent improvement in operational performance measures, as well as evidence of the timescale over which these benefits appear. 相似文献

SUMMARY. There has been controversy for several years about the role of child care reviews-are they for decision-making or only for monitoring progress of children in care. At the heart of this debate have been the questions of involvement of children, their parents, and professionals from other agencies. This article takes forward these arguments based on research in two Scottish social work departments. As well as reporting and discussing the key issues and identifying when different people participate in reviews, it takes in the specific implications of the external monitoring and decision-making role of the Children's Hearing. 相似文献

Correspondence to Dr A. J. Kendrick, Research Fellow, Department of Political Science and Social Policy, University of Dundee, Dundee, DD1 4HN, Scotland. Summary In this second article based upon the first stage of a researchproject on statutory child care reviews in Scotland we explorethe perceptions of the functions of reviews. We identify a numberof primary functions which can be viewed together as elementsin a rational model of decision-making. With certain provisosthis model allows us to distinguish analytically the explicitpurpose of child care reviews. We show that although a numberof other functions take place in reviews these are not perceivedas necessary to reviews and as such can be considered secondaryfunctions. 相似文献

Although the Sherman Antitrust Act is more than a century old, debate continues over its goals. In contrast to what many have argued, I contend that the Act's main goal is to maximize economic efficiency, rather than the welfare of consumers. The Sherman Act is a modest extension of the common law, which the "Law and Economics" literature indicates moves towards economic efficiency. Further, unlike the Interstate Commerce Act of 1887, Sherman Act decisions are made by courts, not a regulatory agency. Thus, the theory of legislature choice also implies that the goal of the Act is to maximize economic efficiency. 相似文献

This paper assesses the effectiveness of union strikes against agricultural industries. Various factors including input substitution possibilities create special challenges for union leaders. We develop the concept of a minimum-effective union and apply it empirically to the 1979 California lettuce strike. To be effective, a union has to reduce producer profits below the prestrike level. In the lettuce strike case, producer profits were actually increased, not reduced. 相似文献
