The utilization of prevailing evaluation policy in the selection of performance measures

This study considers the problem of inferring a functional evaluation criterion from existing performance measure policies. The objective is to develop a rational basis by which to adaptively evaluate a current best set of performance measures from alternative sets. The analysis is based on a matrix approach for relating system characteristics to performance measures across a set of activities. A procedure for ranking measure combinations which are candidate implementation alternatives is devised using this matrix representation and cost information. An example illustrating the procedure is presented.     

Behavioral evaluation of a state program of deinstitutionalization of the developmentally disabled

The purpose of this study was to evaluate one phase of a statewide program of deinstitutionalizing developmentally disabled individuals. Forty adults who had spent a minimum of six months in community placements were evaluated with respect to changes in behavior associated with movement out of state institutions and into community settings such as group homes and day activity centers. Pre- and post-deinstitutionalization measures were taken with the Behavior Development Survey. Post-deinstitutionalization measures on Cataldo and Risley's Resident Activity Manifest were compared to the same measures obtained on 159 developmentally disabled individuals scheduled for deinstitutionalization. A consistent pattern of positive changes on both instruments favored deinstitutionalization, but changes could not be unequivocally attributed to movement out of the institutions per se.     

Pragmatic decisions in the evaluation of consumer satisfaction with mental health treatment

This article examines pragmatic choices which must be made in conducting consumer satisfaction assessment of mental health treatment. It is argued that choices involving sample, format, and procedure for examining satisfaction may influence the results of such research, and must be considered when creating or evaluating these efforts. These choices are examined in detail.     

Evaluating employee assistance programs. A review of methods, outcomes, and future directions

Renewed interest in assisting troubled employees has led to an upsurge in the development of employee assistance programs, coupled with demands for demonstrable effectiveness. This review examines the nature and scope of these programs, their administrative and methodological context, and the types and outcomes of evaluation studies conducted thus far. Proposals for improving future investigations through a number of different approaches and strategies are then made.     

On the limiting properties of social indicators

Characteristics of the population and economic measures that constitute traditional social indicators are compared with more recent “quality of life” measures to demonstrate that social indicators are always value statements at the policy level. The possibility of alternative perspectives is illustrated. It is suggested that an awareness of the assumptions implicit in any given indicator is as important as the data they provide.     

上海股票市场股票收益率因素研究

根据上海股票市场从1995 年7 月到2000 年6 月所有A 股股票的月收益率、价格、市值和 公司财务数据,利用Fama-Macbeth 回归分析方法及构造动态组合方法,分析总市值、流通市值、 价格、账面市值比、市盈率、账面资产负债比等因素对股票回报率的影响. 发现上海股票市场具 有显著的市值效应、账面市值比效应、市盈率效应和价格效应. 这些效应不能用股票的beta 值 来解释. 同时发现Fama- French 的三因子模型不能完全解释这些效应,但在三因子模型的基础 上再加上一个市盈率因子可以很好地解
