The Ecology of Family Guidance in Low-Income Mexican-American and European-American Families*

This two-part study applied an ecocultural perspective to socialization of daily and long-term goals in low-income Mexican-American and European-American families with children in third, fifth, and seventh grades. The first part of the study examined family members' participation and parents' socialization goals and guidance strategies for their children's daily household chores and homework activities. The second part of the study examined parents' long-term aspirations and guidance strategies for their children's educational, vocational, and moral development. For daily activities, results showed that in Mexican-American families both parents and siblings played important roles, whereas in European-American families parents were the primary socialization agents. As predicted, in both groups parents' expertise influenced their guidance strategies. Finally, Mexican-American and European-American parents differed in their relative endorsement of gender, relational, and self-reliance goals for household chores. For long-term goals, parents in both groups held high educational, vocational, and moral aspirations for their children. However, some parents of seventh-graders had lower educational and vocational aspirations than those of fifth- and third-graders. Although expertise consistently influenced Mexican-American parents' guidance strategies, the pattern for European-American parents was mixed. The discussion highlights between- and within-group differences in daily and long-term socialization practices with an emphasis on resources and vulnerabilities in the families.     

Improving on truncated linear estimates of exponential and gamma scale parameters

We consider the problem of estimating the scale parameter of an exponential or a gamma distribution under squared error loss when the scale parameter θ is known to be greater than some fixed value θ₀. Natural estimators in this setting include truncated linear functions of the sufficient statistic. Such estimators are typically inadmissible, but explicit improvements seem difficult to find. Some are presented here. A particularly interesting finding is that estimators which are admissible in the untruncated problem which take values only in the interior of the truncated parameter space are found to be inadmissible for the truncated problem.     

A non-parametric index of tracking

SUMMARY A two-sample version of the non-parametric index of tracking for longitudinal data introduced by Foulkes and Davis is described. The index is based on a multivariate U -statistic, and provides a measure of the stochastic ordering of the underlying growth curves of the samples. The utility of the U -statistic approach is explored with two applications related to growth curves and repeated measures analyses.     

Re-Visioning Attention Deficit Hyperactivity Disorder (ADHD)

Constructionist notions have become commonplace in theoretical discussions of the self, but are seldom translated into consideration of specific social work practice concerns such as ADHD. Explorations of ADHD, on the other hand, typically emphasize a narrow, medically-oriented symptom picture that is devoid of the psychosocial context in which the so-called symptoms emerge. A transactional approach to the understanding of ADHD is advanced. This article promotes a link between constructionism and social work's psychosocial or person-in-environment perspective. Such a perspective supports approaches to the assessment of ADHD that illuminate larger cultural messages and their constraining influence on individual meaning-making. Intervention, conducted at multiple levels, must be geared to the establishment of more hopeful and affirming narratives.     

The minds of a medical director

This article is offered in a nod to all those readers who have been exposed to "whole brain" theory, either through the American College of Physician Executives or elsewhere. As managers struggle with balancing the "left brain" and "right brain" aspects of their work, the author says, they might consider exploiting a third area of activity, or inactivity--the "no brain." This center position can be especially effective in dealing with the high-technology aspects of delivering health care.     

Welfare reform in the 1950s.

Contrary to the impression left by historians, neither welfare expansion nor welfare reform died in the 1950s. Even conservatives believed in the necessity of federal spending for welfare. Disagreements came over the proper ways to spend federal money. The Eisenhower administration propagated a rehabilitation approach in an attempt to use federal money to end individual, state, and local dependence on the federal government. The administration's 1954 social security and vocational rehabilitation laws reflected this approach. Bureaucrats in the Department of Health, Education, and Welfare, working with a Democratic Congress, managed to extend the 1954 laws into a major expansion of federal power, as the passage of disability insurance in 1956 demonstrated. Institutional continuity, not heroic individual effort, provided the dynamic for welfare reform in the 1950s.     

ANALYZING GEOGRAPHICALLY DISCRETE WAREHOUSING NETWORKS BY COMPUTER SIMULATION*

This paper describes a comprehensive simulation modeling approach to the problem of locating warehousing facilities in a fashion that minimizes the cost associated with operating a multi-product, multi-source, multi-destination distribution system. The digital simulation model presented in the study is derived within an “industrial dynamics” framework, utilizes input from an existing management information system, and employs a number of relatively simple heuristic procedures to analyze various alternative warehousing networks. Simulation results, in terms of the distribution costs associated with various warehouse locations, are presented for cases involving the effect of provision of a 100% service level, the effect of constraining product availability and/or inventory capacities at various warehouses, and the effect of deleting various warehouses from the existing warehouse network.     

THE DEVELOPMENT OF AN INTEGRATIVE CURRICULUM IN AN UNDERGRADUATE BUSINESS PROGRAM*

This paper describes how the core portion of the undergraduate business program at Indiana University was revised to facilitate integration of basic functionally oriented decision making skills and thus help students gain a deeper understanding of the interdependence of business decisions. It relates, in essence, why and how a single computer-oriented case study which demanded a solution to a large-scale, unified finance-marketing-production problem was used at Indiana University, mentions how we plan to accomplish further integration of functional material, and provides some insight into student reaction to what was, in fact, a massive project from both student and administrative points of view.
