The aim of the present study was to examine the treatment progress of both adolescent's and their families' functioning in a new compulsory residential treatment program. The sample consisted of 339 admitted adolescents (56.3% boys). The mean age at time of entry was 15.69 (SD = 1.30). Adolescents stayed on average 9.42 months (SD = 4.66) in a new residential treatment program. Data on adolescents' internalizing and externalizing problems were assessed using self-reports, parent reports, and group care worker reports. In addition, adolescents reported their substance use and delinquency and parents also reported family functioning and level of perceived parental stress. The findings revealed a significant decrease in adolescents' self-reported internalizing and externalizing problems, delinquency, and substance use. According to parent ratings, a significant improvement was found concerning adolescents' problem behaviors during treatment. However, according care worker ratings, adolescents showed no improvement on internalizing problems and showed an increase in externalizing problems. Concerning families, although there was no improvement in family functioning, parental stress significantly improved over time. Further research should examine whether improvements experienced during treatment are maintained after treatment. 相似文献

Contingency models of information systems planning predict that no single planning approach will suit all organizations' needs. Little empirical research has been undertaken, however, to evaluate this prediction. Accordingly, we used McFarlan, McKenney, and Pyburn's (1983) strategic-grid model to study the information systems planning problems encountered by 49 governmental agencies. Twenty-seven agencies were required to follow a planning approach best suited to organizations that had a high level of dependence on both their existing and proposed systems. We predicted that agencies not having these characteristics would encounter the most problems with the approach. The remaining 22 agencies could choose their own planning approach. We studied this latter group to determine whether the problems encountered by the first group could be attributed to the mandated approach. Overall, the empirical results obtained were equivocal. Some results indicated that more planning problems were encountered by agencies in which the mandated approach was not appropriate to their position in the strategic grid. Other results were not supportive of this proposition. More work needs to be undertaken, therefore, to evaluate the predictive and explanatory power of contingency models of information systems planning. In addition, our research indicates a need to develop more rigorous theories of information systems planning behaviors, to improve the instruments needed to measure these behaviors, to explore the relationship between information systems planning behaviours and organizational effectiveness, to investigate how organizational learning impacts planning behaviors, and to determine the types of information systems planning problems that diffuse through organizations and those that remain localized. 相似文献

Abstract. This study has been carried out by the Research Centre for Education and Labour Market (ROA) as part of a long-range research project commissioned by the Ministry of Education and Sciences. The objective of the project is to develop an education/labour-market information system to help secondary and university students choose the right type of school and/or occupation (ROA 1988). The study reported on here sets out to disclose the factors underlying the development of the occupational pattern. The shares of occupational classes in each economic sector are taken as points of departure. The explanatory variables are technological progress and cyclical and structural sectoral developments. For each occupational class, an estimation is made with the help of a linear model, the estimation method being that of Weighted Least Squares. To permit several variables to be included in the equation, the data have been pooled over sectors and time. In two fifths of all cases, a model with explanatory variables has been chosen; in the remaining instances a sector-dummy model was found to suffice. 相似文献
