Diabetes mellitus is a rapidly increasing and costly public health problem. Large studies are needed to understand the complex gene-environment interactions that lead to diabetes and its complications. The Marshfield Clinic Personalized Medicine Research Project (PMRP) represents one of the largest population-based DNA biobanks in the United States. As part of an effort to begin phenotyping common diseases within the PMRP, we now report on the construction of a diabetes case-finding algorithm using electronic medical record data from adult subjects aged ≥50 years living in one of the target PMRP ZIP codes. Based upon diabetic diagnostic codes alone, we observed a false positive case rate ranging from 3.0% (in subjects with the highest glycosylated hemoglobin values) to 44.4% (in subjects with the lowest glycosylated hemoglobin values). We therefore developed an improved case finding algorithm that utilizes diabetic diagnostic codes in combination with clinical laboratory data and medication history. This algorithm yielded an estimated prevalence of 24.2% for diabetes mellitus in adult subjects aged ≥50 years.

Objective: The Internet is frequently used as a tool to recruit research subjects, and the US Food and Drug Administration (FDA) provides general guidance regarding such advertising. The goal of this study was to explore the incidence and nature of ethically inappropriate recruiting advertisements on the Internet and to provide descriptive guidance to researchers for responsible Internet recruiting.

Background. Missing data are a significant problem in health-related quality of life (HRQOL) research. We evaluated two imputation approaches: missing data estimation (MDE) and assignment of mean score (AMS). Methods. HRQOL data were collected using the Medical Outcomes Trust SF-12. Missing data were estimated using both approaches, summary statistics were produced for both, and results were compared using intraclass correlations (ICC). Results. Missing data were imputed for 21 participants. Mean values were similar, with ICC >.99 within both the Physical Component Summary and the Mental Component Summary when comparing the two methodologies. When imputed data were added into the full study sample, mean scores were identical regardless of methodology. Conclusion. Results support the use of a practical and simple imputation strategy of replacing missing values with the mean of the sample in cross-sectional studies when less than half of the required items of the SF-12 components are missing.

Since the terrorist attacks of September 11, 2001, aviation security policy has remained a focus of national attention. We develop mathematical models to address some prominent problems in aviation security. We explore first whether securing aviation deserves priority over other potential targets. We compare the historical risk of aviation terrorism to that posed by other forms of terrorism and conclude that the focus on aviation might be warranted. Secondly, we address the usefulness of passenger pre-screening systems to select potentially high-risk passengers for additional scrutiny. We model the probability that a terrorist boards an aircraft with weapons, incorporating deterrence effects and potential loopholes. We find that despite the emphasis on the pre-screening system, of greater importance is the effectiveness of the underlying screening process. Moreover, the existence of certain loopholes could occasionally decrease the overall chance of a successful terrorist attack. Next, we discuss whether proposed explosives detection policies for cargo, airmail and checked luggage carried on passenger aircraft are cost-effective.; (cont.) We define a threshold time such that if an attempted attack is likely to occur before this time...

This book advances a research agenda for a little studied topic, namely the popular culture of disasters (PCD). We systematically although selectively outline some possible fruitful topics and questions that researchers might address. However, no effort is made to present a full and total research agenda for the future. Instead, our focus is on those issues that at the present time might have the greatest potential. We regard these issues as being the most worthwhile, in the short term, to develop our understanding and knowledge.

The Disaster Research Center (DRC) was established at the Ohio State University in 1963 and moved to the University of Delaware at the end of 1984. The Center was the first of its kind in the world and is the oldest in the United States. At the present time it is one of the extremely few research operations anywhere that maintains stand-by teams ready to launch immediate field studies of impending disasters and actual disaster impacts.

The terrorist attacks on the United States on September 11, 2001 (9/11)resulted in the costliest and deadliest disaster in the nation's history. These attacks manifested the nation's vulnerability to these types of disasters and demonstrated that the country was not prepared to confront an event of this magnitude and complexity. However, social science research has shown that the organizational resilience of emergency maangement organizations enhanced their capacity to respond to this devastating event (Kendra and Wachtendorf, 2003a). This terrorist attack reinforced what the social science disaster literature has shown for other types of disasters and emergencies: that planning, coordination, and communication are critical elements in preparing, responding, and recovering from a disaster.

Systematic and extensive social science disaster research has been going on for nearly five decades now. Much worthwhile work has been done. A very large number of empirical generalizations have been produced. Yet, I am troubled. In my view, the field more and more, is producing less and less, of what might be characterized as major advances in new knowledge and understanding of disaster related phenomena. Certainly one would be hard pressed to point to the production of new theories, models, explanatory schemes and/or master hypotheses about the phenomena that are notably different from what have been around for some time. In fact and worst, both relatively and absolutely, little of the literature advances explicit theories, models, explanatory schemes and or master hypotheses of any kind. A partially completed informal content analysis of journals that publish disaster research articles in the social sciences support this contention.

This paper summarizes much although not all of what is known about overall disaster related social behavior. Drawing from a base of 50 years of social science research involving thousands of studies, we note the typical patterns of behavior at the individual, organizational, community and mass media levels. The last is a surrogate for reactions at the societal level. To avoid interminable and specific documentation, readers are presented a large bibliography at the end of this paper that lists the major research literature examined for the purpose of this essay. Most disasters impact a community. However, there are non-community types of disasters, e.g., a plane crash in an isolated rural area. This affects behavioral responses (e.g., crash survivors do not receive the social support that emerges in a community when residents have undergone a common disaster experience). The 20 general observations below around which we organize our comments, are mostly about community disasters. This is the paper written as background for the oral remarks to be made at the 8Th International Symposium on Natural and Technological Hazards: Hazards 2000 to be held in Tokushima, Shikoku, Japan, May 21-25, 2000.
