Older Drivers Retiring From the Road: An Application of the Selection,Optimization, and Compensation Model

Purpose: This study uses the selection, optimization, and compensation (SOC) model to compare older adults who have given up driving, those who still drive, and those who drive less to identify differences in the three groups. Design and Methods: This cross-sectional study of 281 older adults is part of the Naturally Occurring Retirement Community Demonstration Project. Study participants completed interviews that included questions on demographics, health and functioning, mental health, social support, and current levels of engagement in activities including current driving status. Results: Data suggest that driving retirement is a process and that a substantial number of people are in the transitional stage, where they are less functional than those who still drive and more similar to those who have retired from the road. Implications: Given the similarity of those who drive less to those who have given up driving, front-line professionals and policy makers must work together to ease the transition to driving retirement for those without adequate ability to effectively compensate for their inability to continue to drive safely.     

Founders' syndrome in women's nonprofit organizations: Implications for practice and organizational life

This qualitative study examines the impact of “founders' syndrome” in ten feminist nonprofit organizations, giving attention to the ways in which original members and organizers (founders) retain control and set the agenda of these organizations beyond their official terms of office. In these community‐based organizations, founders' syndrome provides stability, but it also affects the ability of younger members to contribute and influence organizational direction. Implications for practice are drawn from the study's results.     

Point Estimates of Test Sensitivity and Specificity from Sample Means and Variances

In a wide variety of biomedical and clinical research studies, sample statistics from diagnostic marker measurements are presented as a means of distinguishing between two populations, such as with and without disease. Intuitively, a larger difference between the mean values of a marker for the two populations, and a smaller spread of values within each population, should lead to more reliable classification rules based on this marker. We formalize this intuitive notion by deriving practical, new, closed-form expressions for the sensitivity and specificity of three different discriminant tests defined in terms of the sample means and standard deviations of diagnostic marker measurements. The three discriminant tests evaluated are based, respectively, on the Euclidean distance and the Mahalanobis distance between means, and a likelihood ratio analysis. Expressions for the effects of measurement error are also presented. Our final expressions assume that the diagnostic markers follow independent normal distributions for the two populations, although it will be clear that other known distributions may be similarly analyzed. We then discuss applications drawn from the medical literature, although the formalism is clearly not restricted to that application.

Contradictions in Agrarian Ideology: Restructuring Gender,Race-Ethnicity,and Class1

Abstract Contradictions in agrarian ideology are revealed through an analysis of social dimensions of economic restructuring in rural Iowa. Data are culled from field observations and in-depth interviews with white European American residents. How rural residents cope with and make sense of the changes within their communities are two interrelated dimensions of social restructuring. The research highlights a perception of sharpening social and economic divisions within two small communities. The social and economic changes challenged residents' self-definitions, perspectives on rural community life, and previously taken-for-granted notions of gender, racial-ethnic, and class relations. Analysis of field data demonstrates contradictory ways that discourses on agrarianism and gemeinschaft serve as resources as well as impediments to social support and community development.
