Business games and implementation research

This paper reviews some recent research in OR implementation and suggests that a new approach is required, which will take fuller account of the perceptions of managers concerned with the problem. Research games in business settings seem to offer a means for such approach. Some lessons learned from a business game used in this way are described and their implications for modelbuilders are discussed.     

Two hospice patients and the roles of the physician and the physician executive

Hospice care is available nearly everywhere. Yet some physicians aren't aware of its role in end-of-life care. Explore what hospice care provides and how patients and their families may benefit.     

Experience with a multi-year fleet planning model

The fleet planning problem requires determination of the changing airline fleet mix based on existing traffic levels and projected growth, on the existing fleet, various aircraft types available in the future, and other operational and financial considerations. Several applicable mathematical formulations have been reported. One of these has been programmed for the computer and used by the authors for several years. This paper discusses the application of that model to real airline planning situations. Such practical experience has effected changes in the program and the manner it is used in fleet planning studies.     

Outcomes of a technology-based social norms intervention to deter alcohol use in freshman residence halls

OBJECTIVE: The authors tested a prototype intervention designed to deter alcohol use in residence halls. PARTICIPANTS: Approximately 384 freshmen participated in the study over a 2-year period. METHODS: The authors devised a feedback method that assessed residents' blood alcohol concentration (BAC) at night and allowed the readings to be retrieved the next day via the Web. Residents in an intervention hall received their BAC readings as well as normative feedback. In a comparison hall, residents could retrieve only the BAC readings. RESULTS: The authors found statistically significant hall differences, but they were small in size and not meaningful. CONCLUSIONS: Qualitative findings suggest the intervention had an overall positive impact, but the actions of a subgroup of rebellious drinkers might have obscured the effect. Social norms interventions could provoke some episodes of excessive drinking in students who find these messages objectionable. More research is needed to evaluate delayed BAC feedback.     

A Mandatory Student Health Insurance Program at a Large State University

Abstract

A new compulsory-with-waiver health insurance plan at the State University of New York at Buffalo (SUN-YAB) was designed in 1976 after assessing available literature on students' insurance, morbidity, health care costs, attitudes, data from past SUNYAB insurance plans and health service statistics. Previous findings that the morbidity of this population is low is corroborated by the data available on the students considered within this project. Illnesses common to this age group are predominantly acute, and require a low rate of hospitalization. The new insurance program cost an unmarried single student $67.00 and was a success by several criteria. Approximately 5,000 more students were enrolled in the complusory plan than in the previous voluntary one. Among students interviewed, both those who enrolled and those who did not, felt that the idea of compulsory health insurance for students was a good idea. Virtually all full-time students in the university were covered by some health insurance.     

Hard and soft constraints in linear programming

The linear programme and its constraints are split into two parts. The first consists of the traditional structure, the second being akin to goal programming. SOFT constraints are weighted relative to each other and then approximately weighted relative to the HARD constraints. The LP is run four times giving different emphasis to the SOFT and HARD constraints. The manager requesting the LP has then to decide which gives the most appropriate solution.     

A close look at why one social norms campaign did not reduce student drinking

The authors examined 3 possible explanations for the failure of a social norms campaign at a large public university. They administered an anonymous survey to 2 random samples of undergraduate classes: a baseline assessment of 616 students before the campaign's implementation and a follow-up survey of 723 students 4 academic years later. At follow-up, 66.5% of the students were aware of the campaign, yet the survey revealed no reduction in perceived drinking norms or alcohol use in this group. An analysis of the postcampaign sample revealed that (1) a majority of the students did not find the statistics used in the campaign messages credible, (2) higher levels of alcohol use predicted lower levels of perceived campaign credibility, and (3) only 38.5% of the students understood the campaign's intended purpose. If they are to influence personally relevant drinking norms, these campaigns must undergo further development to enhance message credibility and participants' understanding.
