Interlakes community health centers: A case study

Interlakes Community Health Centers (ICHC) provides primary health care services to low-income people in a medium-size city. ICHC expanded from three to five service centers and soon ran into problems meeting payroll. Several strategic management dilemmas stem from this crisis.     

THE REDUCED-RANK GROWTH CURVE MODEL FOR DISCRIMINANT ANALYSIS OF LONGITUDINAL DATA

This paper presents a method of discriminant analysis especially suited to longitudinal data. The approach is in the spirit of canonical variate analysis (CVA) and is similarly intended to reduce the dimensionality of multivariate data while retaining information about group differences. A drawback of CVA is that it does not take advantage of special structures that may be anticipated in certain types of data. For longitudinal data, it is often appropriate to specify a growth curve structure (as given, for example, in the model of Potthoff & Roy, 1964). The present paper focuses on this growth curve structure, utilizing it in a model-based approach to discriminant analysis. For this purpose the paper presents an extension of the reduced-rank regression model, referred to as the reduced-rank growth curve (RRGC) model. It estimates discriminant functions via maximum likelihood and gives a procedure for determining dimensionality. This methodology is exploratory only, and is illustrated by a well-known dataset from Grizzle & Allen (1969).     

The Treatment of Sexual Disturbance

The thesis of this paper is that the highly competent marriage and family therapist had better have good understanding of both general disturbance and sexual disturbance. A case illustration of an individual with a sexual disturbance is given. Editor.     

Labor union effects on innovative activity

Union rent-seeking is considered a tax on firm returns from investments in innovative activity. We examine this proposition by considering the responses of firms in a 1985 survey on R&D and product innovation. Consistent with our model, we find that innovative activity is significantly less important for union than for similar nonunion firms. We conclude that innovative activity may be an important route through which union rent-seeking affects the long-run performance of firms. We appreciate the helpful assistance and suggestions received from our colleague Terry Seaks, Barry Bozeman at Syracuse University, and participants in the Vanderbilt Microeconomics Workshop.
