THE ROLE OF MARITAL STATUS IN HEALTH SERVICES EXPENDITURES FOR PSYCHIATRIC OUTPATTIENTS

This study tested the hypothesis that married psychiatric outpatients would have lower total health services expenditures than divorced or separated patients. Chart review of the 471 individuals attending an academic medical center outpatient psychiatric clinic during 1994 identified 131 married, 40 separated, and 93 divorced patients. Separated men had significantly higher average total charges ($16,890) than married ($5,279) or divorced ($5,539) men by one-way ANOVA (p < .05). The nonparametric Mann-Whitney test also showed that separated men had higher charges than married or divorced men. There were no differences between marital status groups for women.     

Union-Nonunion differentials and establishment size: Evidence from the NLSY

We provide new empirical evidence on union-nonunion differentials using the 1990 wave of the National Longitudinal Surveys of Youth (NLSY) data set which allows us to examine a broader set of fringe benefits than most other studies and provides a rich set of control variables. Our major finding is that the union effect decreases with establishment size for both components of the compensation structure, i.e., wages and fringe benefits. An earlier version of this paper was presented at the Southern Economic Association conference in Washington, DC in 1996. We thank Tom Hyclak and other session participants.

(Dis)respecting versus (Dis)liking: Status and Interdependence Predict Ambivalent Stereotypes of Competence and Warmth

As Allport (1954) implied, the content of stereotypes may be systematic, and specifically, ambivalent. We hypothesize two clusters of outgroups, one perceived as incompetent but warm (resulting in paternalistic prejudice) and one perceived as competent but not warm (resulting in envious prejudice). Perceived group status predicts perceived competence, and perceived competition predicts perceived (lack of) warmth. Two preliminary surveys support these hypotheses for 17 outgroups. In-depth analyses of prejudice toward particular outgroups support ambivalent prejudice: Paternalistic prejudice toward traditional women, as well as envious prejudice toward career women, results in ambivalent sexism (Glick & Fiske, 1996). Envious prejudice toward Asians results in perceived competence but perceived lack of social skills. Ambivalent content reflects systematic principles.     

Quality costing: a management review

This paper relates a review of the English language literature on quality costing and traces its historical development; it provides authoritative reading on the subject. The review also has a focus on collection and use of quality-costing methods, quantitative cost data and the role and views of accountants in the task of quality-cost collection and reporting. Amongst the main findings is the preoccupation with the prevention – appraisal – failure categorization of quality costs and lack of guidance on definitions. The considerable impact of the American quality profession on the development of quality costing is pointed out along with the increasingly positive stance of accountants.     

Exercising Property Rights to Pollute: Do Cancer Risks and Politics Affect Plant Emission Reductions?

This paper examines whether firms' decisions about reductions in toxic emissions depend on the magnitude of dangers arising from their pollution and on who bears pollutant risks. Controlling for the quantity of air toxics released in 1988, this article finds that plants whose emissions generated higher numbers of expected cancer cases did reduce their emissions more between 1988 and 1991. The nature of the community bearing the pollution risk also affected firm decisions. The higher the voter turnout in the area, a proxy for residents' likelihood of collective action, the greater the reductions in a plant's release of air carcinogens.     

Modelling Variability in the Branching Structure of Strawberry Inflorescences

The branching structure of inflorescences of the cultivated strawberry ( Fragaria × ananassa Duch.) is very variable. This paper demonstrates that some aspects of this variability are well described by a simple stochastic model of branching that has two adjustable parameters. The model is shown to provide a good fit to data from a set of almost 700 inflorescences of the cultivar Elsanta, collected over two successive years. For one parameter the maximum likelihood estimator is a moment estimator which is fully efficient even if the detailed branching structure of the inflorescences is not recorded. This parameter provides a convenient summary of branching vigour. The maximum likelihood estimator of the second parameter must be determined iteratively and can be quite inefficient unless the full branching structure is recorded. The model demonstrates that branching structure is affected by the order in which inflorescences emerge on the plant.     

e‐Integration in the Supply Chain: Barriers and Performance*

Current opinion holds that Internet‐based supply chain integration with upstream suppliers and downstream customers (called “e‐integration” in this paper) is superior to traditional ways of doing business. This proposition remains untested, however, and similarly we know little about what are the upstream, internal, and downstream barriers to implementing e‐integration. This paper empirically addressed these questions using data from a large single nation study, and found (1) a positive link between e‐integration and performance, and (2) that internal barriers impeded e‐integration more than either upstream supplier barriers or downstream customer barriers. Findings from this study contribute to our theoretical understanding of implementing change in contemporary supply chains, and have important implications for manufacturers interested in improving their supply chain's performance using the Internet.
