This article explores the theoretical and empirical issues in unit root nonstationarity for multiproduct acreage response systems. A wheat/barley acreage response system for the praire provinces region of Canada is estimated and the existence of a unit root cannot be rejected empirically. It is shown that while the estimates of this system are very similar whether or not a unit root is assumed, the effects of a one-shot policy shock in the two alternative models are very different. 相似文献

The present outcome study is a preliminary report on whether personality changes occur in parents receiving behavioral family therapy. Behavioral techniques for changing the identified patient's presenting problem were taught to the parents and each family member was given a weekly behavioral homework assignment intended to change the dysfunctional interactions assessed in the family.
An analysis of pre and post measures using Cattell's 16PF questionnaire showed a significant decrease in the parent's self-sufficiency index, indicating increased group dependence. The mean number of sessions was 12.6. The results of this study raise questions about the nature of the personality changes occurring in family therapy of this type. Family therapists, often-times assuming the role of the "expert" for the family, may be unwittingly fostering group dependence and losses in confidence for parents receiving such family guidance. 相似文献

While effective communication is recognized as important to marital adjustment, few therapeutic alternatives specifically attempt to teach improved communication skills in a systematic manner. In this study, five couples experiencing marital difficulties participated in a traditional therapy group with emphasis upon cathartic release and problem solving. A similar group of five couples participated in a training group consisting of a systematic didactic and experiential approach emphasizing the ability to discriminate and communicate helpfully. The results of outcome measures assessing gain in interpersonal skills and overall functioning indicate significant improvement in the training as compared to the traditional group. 相似文献

The prevention of foster care became an important issue for child welfare services during the 1970s. Two main types of prevention models have emerged: crisis intervention programs intended to prevent imminent placement and intensive service programs designed to avert those crisis situations that precipitate placement. A critical analysis of several project evaluations leads to the conclusion that neither model has been markedly successful. Low nominal project placement rates seem attributable to inability to predict placements and to client selection biases. From a strictly financial perspective, preventive services have been considerably more expensive than regular services, including temporary family foster care. Data from a new demonstration project in New Jersey illustrate various problems in providing and evaluating preventive services to families referred to protective service agencies. Implications of the findings for prevention programs and policies are discussed, and a new direction focused on truly early intervention with children and families is proposed. 相似文献

SONET-I is a preliminary but completely operational version of a package of computer programs for the analysis of social structure. The programs were written to implement a strategy for the analysis of social networks which the authors have developed over the past several years. The conceptual basis for the research method has its origins in graph theory on the one hand and in anthropological studies of social organization — especially kinship studies — on the other. The method can, in fact, be seen as a graph theoretic formalization and generalization of kinship-based methods of social analysis often associated with British social anthropology. 相似文献

Social indicators and program evaluation research have much in common. Quality of life work specifically raises the question of objective versus subjective variables, aggregate data versus distributional and individual issues, and the reference standards used in judgment and evaluation decisions. This article presents perspectives on these issues from the orientation of quality of life research and proposes that these approaches have relevance for program evaluation work. 相似文献
