Using macro variables in program evaluation

This paper discusses the importance of using macro-level variables for program analysis. It is argued that three types of macro variables--cultural, economic, and demographic--provide a context for evaluation, and offer alternative explanations for the success or failure of a program. The problems of causality and availability of data are discussed. Macro variables are seen to be especially useful in "meta evaluation," and in integrating the results of specific program evaluations into general conclusions.     

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.     

Frustrated fertility: a population paradox

This Bulletin examines the causes of subfecundity -- the diminished ability to reproduce -- and its effect today and in the past on the fertility, or actual reproductive performance, of individuals and, hence, populations. By definition, all real populations are subfecund since all experience some degree of involuntary biological factors affecting coitus, conception, or the ability to carry a conceptus to live birth which reduces their fecundity below the estimated biological population maximum of 15 children per woman. Affecting both men and women, these factors fall into 5 categories: genetic factors such as blood group incompatibilities and inherited sickle cell anemia or diabetes; psychopathology, including psychic stress and behavioral disorders (e.g., drug and alcohol abuse); infectious diseases such as gonorrhea, malaria, tuberculosis, and postabortion infection; malnutrrition, including the chronic undernutrition of the 3rd World and the overnutrition of developed societies; and hazards posed by increasing amounts of radiation and toxic chemicals in the environment. Reducing subfecundity requires improved living conditions, avoidance of or protection from known hazards, and adoption of medical advances which now can help 40 to 60% of subfecund couples. But even in the U.S. fertility would certainly rise among the 15% of couples now estimated to be involuntarily childless and the 10% who have fewer children than they want, and among disadvantaged groups, and teenagers.

Pesticide exposure and sprayer design: ergonomics evaluation to reduce pesticide exposure

Plant protection products are used in agriculture to improve yields, but this use can cause contamination of the environment and is also likely to have adverse short and long term effects on agricultural workers. This poster describes a systems approach to reducing the risk of operator exposure to plant protection products through the introduction of ergonomics to the design process of large agricultural sprayers.     

How to reduce workload--augmented reality to ease the work of air traffic controllers

In the future the air traffic will rise--the workload of the controllers will do the same. In the BMWi research project, one of the tasks is, how to ensure safe air traffic, and a reasonable workload for the air traffic controllers. In this project it was the goal to find ways how to reduce the workload (and stress) for the controllers to allow safe air traffic, esp. at huge hub-airports by implementing augmented reality visualization and interaction.
