TMR: An Automated System for Managing Revenue

Abstract

The Total Medical Record (TMR) system used by the Division of University Health Services at Duke University is an integrated medical and management information system. One module supports the financial needs of the division. To facilitate managerial performance, TMR automatically prints insurance claims, refund statements, revenue summary data, service utilization, itemized visit statements, monthly patient bills, dunning letters, and has a host of unique features that aid management with controlling the private fees generated by the University Health Services. In addition, the servicing of prepaid programs is accommodated, and the splitting of charges between prepaid and fee-for-service programs occurs automatically.

Abstract

In the field of stress research it is often assumed that social support as well as coping behaviour contributes to feelings of health and well-being. However, until now it has not been altogether clear whether a main-effect model or a buffer model was the more appropriate for explaining the role of these factors in response to stressful situations. In this paper, a research project is described in which both the direct and indirect effects of social support and coping were studied in the work situation of nurses. The results offer more support for a main-effect model than for a buffer or moderating-effect model, especially with regard to the coping strategies ‘active problem-solving’ and ‘palliative behaviour’. However, some moderating effects on nurses‘ reactions to their work situation were found for social support and for ‘comforting cognitions’ as a coping strategy.     

Social interactions and the salience of social identity

We explore the effect of identity salience on behaviour in a simple social interaction. Specifically, we compare ultimatum bargaining across three treatments: priming subjects with a shared identity, priming subjects with an identity distinct from those with whom they will interact, and priming subjects with no particular identity. We find that subjects are most cooperative in the identity-priming treatment and least cooperative in the distinctiveness-priming treatment. Similarly, subjects reveal the highest demands in the identity-priming treatment and the lowest demands in the distinctiveness-priming treatment. We discuss the implications of these results with respect to the literature on organizational identity.     

Developing a Personal Program for Continuing Education

Abstract

The increasing number of field expeditions studying or working abroad each year is currently unparalleled by medical research efforts or data from which health professionals can make meaningful recommendations about how to keep personnel in the field healthy. The medical planning, organizing, and data are presented from a geology expedition to Guatemala involving 25 persons. Only minor medical problems were encountered, and less than 1% of the total person days at risk were lost due to illness. Eight guidelines are presented as a tool to assist any health professional in the planning and preparing of a team for the field.     

Energy modeling as a tool for planning

This paper discusses the application of a general equilibrium model, developed at Stanford Research Institute, for use in long range forecasting and business planning. The value of the modeling approach is illustrated through application to a hypothetical natural gas liquefaction venture. Specific features and representative output of the SRI model are presented. The authors stress the use of a modeling approach in the planning process as a quantitative means of evaluating the importance of uncertainty in specific decision variables and the ability of such model to test explicitly the long term impact of changes in a given set of base assumptions.     

Prior elicitation in the classification problem

Results are developed concerning the asymptotic behaviour of the Bayes classification rule as the number of unclassified observations grows without bound. It is shown that unclassified observations serve only to estimate the individual population parameters in an unlabeled sense and do not provide information about the labels that are attached to the populations. Prior construction is approached through investigation of prior odds over regions of the joint parameter space (across all populations) deemed likely to contain the true joint parameter vector. It is shown that consideration of these prior odds can lead to more robust a posteriori classification of individual observations.     

The employment disadvantage of being a smoker

Three studies were done to examine the effects of being a tobacco smoker on employment prospects. In Study 1, thirty-two subjects reviewed application forms and rated four applicants as prospective employees. The subjects rated the nonsmoker version of the job applicants significantly more highly for hiring. In Study 2, forty-four subjects stated whether they preferred to hire smokers or nonsmokers and estimated the preference of employers generally. Those who stated a personal preference gave their reasons. Seven personal reasons for preferring a nonsmoker were mentioned by at least two subjects. The reasons ranged from dislike of tobacco smoke to concern about smokers taking more sick leave. In Study 3, which involved forty-six subjects, degree of endorsement of the attitudes underlying four of the seven preference reasons were found to be associated with degree of preference for non-smokers. The results of the three studies provide potentially useful information for job applicants and for individuals who design smoking prevention interventions.
