Visible Minorities and Majority Giving

We examine if the presence of minority individuals in the community affects the decision to give to charities by majority individuals. We focus on two giving decisions by the majority population. The first is giving to any charitable organization; the second is giving to organizations geared to international causes. We also examine these two decisions when the sample is split into religious and non-religious individuals. We find that the larger the proportion of minorities in a given community, the less likely that members of the majority group give to charity in general—supporting the idea that heterogeneous communities deter outreach—but the more likely they are to give to international causes, giving credence to Allport’s ‘contact’ hypothesis.     

The evolution and problems of model management research

Models are a key resource for organizational decision making. The diversity, complexity, and reusability of this resource result in the need for model management systems. The construction of a model management system involves a modeling task dimension and a design level dimension. The modeling task dimension consists of model formulation, model representation, and model processing. The design level dimension addresses the architectural requirements of a system from a user's standpoint and a computer system's standpoint.The numerous architectures suggested in the model management systems literature address isolated areas identified by these dimensions. The research surveyed in this paper indicates that the primary focus has been on the system view of model representation. Before model management systems can be widely used in organizations, model management researchers must explore systems that address all areas of the task and design level dimensions.In this paper, we identify and justify the necessary dimensions of model management research. Next, the existing model management research is critically reviewed. Finally, neglected research areas are discussed, and investigations necessary for the development of integrated model management systems are suggested.     

The world economic system and international migration in less developed countries: an ecological approach

This study examines net migration in less developed countries (LDCs) within the context of a world economic system and an urban ecological framework. Data are obtained from the "1987 World Development Report," the "1983 and 1987 World Bank Tables," and the 1984 UN Demographic Yearbook. It is posited that international migration is a direct response to the changes in the ecological subsystems in LDCs. The framework of this analysis relies on analyses by Sly and Tayman that found in multi-equation models that migration was a demographic response to environmental conditions created by organization and technology. The maximum likelihood estimates derived from the proposed structural model indicate that net capital flows positively influence net migration rate directly. Large transfers of capital were associated with net migration. It is suggested that a reduced percentage in the labor force in agriculture may have a greater impact on emigration than wages or social disadvantages. Gross national product had a smaller impact on migration than net capital outflows. Exports had a positive impact on net migration. There was a direct negative effect of value added to manufacturing on net migration, and the direct negative effect was greater than the positive indirect effect. The percentage of persons economically active had a positive impact on net migration. Increased economic activity was related to increased emigration. The evidence suggests that world economic systems did have an impact on emigration, when profits were not invested in domestic economies of LDCs. Findings suggest that the value added to manufacturing, the percentage engaged in agriculture, and the economically active population mediated the impact of trade on net migration.     

Three strikes and you're out: Demographic analysis of mandatory prison sentencing

Much of the debate about the costs and benefits of “three-strikes” laws for repeat felony offenders is implicitly demographic, relying on unexamined assumptions about prison population dynamics. However, even state-of-the-art analysis has omitted important demographic details. We construct a multistate life-table model of population flows to and from prisons, incorporating age-specific transition rates estimated from administrative data from Florida. We use the multistate life-table model to investigate patterns of prison population growth and aging under many variants of three-strikes laws. Our analysis allows us to quantify these demographic changes and suggests that the aging of prison populations under three-strikes policies will Significantly undermine their long-run effectiveness.     

Diagnostic bias in organizational consultation

This article is intended to improve consultation practice by explaining the significance of models, heuristics, and diagnostic aids in organizational diagnosis. The role of diagnostic models in determining the consultant's frame of reference is explained. Evidence that organizational consultants consciously use diagnostic models is provided by citing two independent studies that revealed about 70% of the consultants reported that a diagnostic model was used. The availability, representativeness, and anchoring heuristics used by diagnosticians are summarized and examples of their use are cited. Readers are warned that bias occurs from misapplying the heuristics. However, guidance on correctly applying the heuristics is provided. The development and improvement of diagnostic expertise is explained from the perspective of learning through education as well as feedback received from clients, colleagues (as shadow consultants and as consulting team members), and self. Thus, written from the perspective of a consultant, the article provides a practical presentation on diagnostic bias, supported by theory and empirical research. It should appeal not only to a consulting constituency (i.e. practicing consultants, consultant trainers, and novice consultants), but also to the large number of potential clients (i.e. organizational decision-makers). Future research directions are discussed in terms of (1) the research that has identified relationships between consultant characteristics (e.g. Jungian constructs) and diagnostic information, and (2) the potential of expert systems in organizational diagnosis.
