The disassembly line: balancing and modeling,by S.M. McGovern and S.M. Gupta

This note addresses a problem faced by an actual firm. The problem is to decide on the optimal level of product quality. In performing the economic analysis to determine product quality level, the firm considers revenue, production costs, and research and development costs. However, this note shows that ignoring inventory costs in the analysis will lead to suboptimal product quality levels. Also, including inventory costs in the analysis will lead to reduced production lot sizes. Numerical examples are used to illustrate the results of the model.     

Current Directions in Risk Research: New Developments in Psychology and Sociology

This article reviews the main approaches to risk in psychology and sociology and considers recent developments. It shows that research continues from a wide range of perspectives. Some developments in psychological thinking have recently acknowledged the importance of the cultural framing of risk perceptions and responses and the positive power of emotions to manage uncertainties, while some streams of work in sociology have moved toward more individualist approaches. These converging processes open opportunities for cross-fertilization and for using insights from both disciplines in the development of research.     

The Retirement Syndrome:: The Psychology of Letting Go

This article analyzes a problem that can be described as the retirement syndrome. In exploring the difficulties many leaders face in letting go at the end of a full career, it reviews a number of the barriers to exit: financial, social, and psychological. It looks at the physical and psychological effects of aging, in the context of retirement; examines the experience of nothingness that single-minded careerists often feel after retirement; describes the talion principle, a subliminal fear of reprisals; and discusses the ‘edifice complex,’ the wish to leave behind a legacy. The article concludes with suggestions as to how individuals and organizations can develop more effective and humane disengagement strategies.

The Risk of Photochemical Reactions

In January 1987, an incident occurred at a petrochemical complex in Salavat, Russia. The incident resulted in the poisioning of 17 people by the products of photochemical smog. This paper describes the incident and discusses the possibility of chemical reactions that pose toxic hazardous situations for chemical plant personnel. Pollutants present in the atmosphere as a result of continuous releases can result in the formation of toxic substances and the poisioning of people, even when permissible levels of concentrations are not exceeded for the initial pollutants. In addition, this paper addresses the need to consider the possibility of secondary chemical reactions in the environment while planning chemical plant activity.     

Risk Perception and Risk Talk: The Case of the Fukushima Daiichi Nuclear Radiation Risk

Individuals’ perceptions and their interpersonal communication about a risk event, or risk talk, can play a significant role in the formation of societal responses to the risk event. As they formulate their risk opinions and speak to others, risk information can circulate through their social networks and contribute to the construction of their risk information environment. In the present study, Japanese citizens’ risk perception and risk talk were examined in the context of the Fukushima Daiichi nuclear radiation risk. We hypothesized and found that the risk information environment and risk literacy (i.e., competencies to understand and use risk information) interact to influence their risk perception and risk talk. In particular, risk literacy tends to stabilize people's risk perceptions and their risk communications. Nevertheless, there were some subtle differences between risk perception and communication, suggesting the importance of further examination of interpersonal risk communication and its role in the societal responses to risk events.     

The Dynamics of Risk Perception: How Does Perceived Risk Respond to Risk Events?

This paper examines the relationship between perceived risk and experience. This research addresses the processes by which people learn about risk and choose among real life prospects with associated uncertainties, risks and benefits. By comparing the impact of acute risk events with that of chronic risk events on public perception of risk during and after the events, this research focuses on the learning processes that characterize what kinds of risk events alter the perception of risk. Comparing materialized hazards at existing facilities with the risks associated with potential facilities, this research addresses risk choices among real life prospects. This study uses a classic pre-post quasi-experimental design. Surveys conducted in the Spring of 1992 on perceived and acceptable risk in Odessa and La Porte, Texas were conducted prior to risk events. Respondents from that survey were re-interviewed in the Spring of 1993 after the risk events to form a panel design. This paper analyzes the affect of risk events on perceived risk and the implications of these experiences for public policy concerning technological risk. The empirical results suggest that the social processes that construct and maintain risk in the public eye are at least as important as, if not more important than, the physical and psychological dimensions of risk.     

The medical director as educator: an interview with Elizabeth M. Gallup, MD, JD, MBA. Interview by Richard L. Reece

Richard L. Reece, MD, interviewed Elizabeth M. Gallup, MD, JD, MBA, on July 9, 1999, to talk about the evolving role of the physician executive. Dr. Gallup discusses how medical directors have evolved from a purely clinical role to participating in the business side of medicine as well. The traditional medical director, a Dr. No who denies treatment and watches clinical performance, is now becoming an educator helping physicians to manage their behavior and change their practices based on comparative data. Her book, How Physicians Can Avoid Surrender and Lead Change: Gaining Real Influence in Your Own Health Care Organization Before It's Too Late, (American College of Physician Executives, 1996) promotes acting together as a group if physicians want to stay independent and not become employed. Independent physicians can form IPAs and act together as a group, avoiding some antitrust laws. Unless physicians get together and act as a group, she says, they are doomed to further and further erosion of their economic interests as well as their clinical autonomy.
