“Sorting Out” collective leadership: How Q-methodology can be used to evaluate leadership development

Q-methodology has proven to be an effective way to solicit participants' perceptions of outcomes. In this article, Q-methodology is described as a data collection tool that can be used to better evaluate the development of collective leadership. Additionally, this methodology provided a valuable tool for participants themselves (leadership development) and evaluators (evaluation development). In writing this article, we drew upon data from a longitudinal study of the Kellogg Leadership for Community Change (KLCC) initiative at six sites from 2002 through 2007 where multiple data collection strategies were employed, including Q-methodology.     

Ethics in population-based genetic research

Population-based genetic research, including genetic epidemiology, shows tremendous potential to elucidate the role of genes as causal factors in complex and common human diseases. Like all research with human subjects, full realization of these benefits requires careful attention to its ethical conduct, establishing an appropriate balance between individual protections and the advancement of scientific and medical knowledge. This article reviews the growing literature on genetics research and ethics to describe some of the fundamental ethical issues in population-based genetics research, including research design, recruitment and informed consent, and dealing with research results. Its focus is on areas where consensus is forming and where future work is needed.     

Binge drinking in female college students: the association of physical activity, weight concern, and depressive symptoms

As an initial step in building gender-specific binge drinking intervention programs, the authors investigated the relation of potentially modifiable factors (physical activity level, weight concern, and depressive symptoms) to binge drinking while controlling for the effects of previously established correlates of binge drinking (tobacco and marijuana use, GPA, and perception of peer alcohol use). Four-hundred-twelve college women completed an in-class survey. Multivariate analyses revealed that tobacco and marijuana use, GPA, and physical activity were significantly associated with binge drinking, whereas tobacco use and perception of peers' alcohol use were associated with more frequent binge drinking. The findings suggested that the variables associated with any binge drinking and frequency of binge drinking may differ and that binge drinking can be associated with positive health behaviors (ie, greater physical activity) as well as risky health behaviors (eg, tobacco use).     

Factor Analysis of Barriers to Treatment for Problem Gambling

Attitudes toward problem gambling treatment were investigated in a telephone survey of 1,203 persons in Central Queensland Australia (598 women and 605 men, mean age = 45.8 years). Survey items were compiled from existing substance abuse questionnaires (Center on Alcoholism, Substance Abuse and Addictions, 1995; Sobell et al., 1991). An exploratory factor analysis identified five potential barriers to treatment, including: availability, stigma, cost, uncertainty, and avoidance. Relative to those with few problems, respondents who had numerous gambling problems were more concerned about treatment costs, and the availability and effectiveness of treatment. In addition to the above concerns, older persons more often negatively judged the treatment seeker. In contrast, educated respondents had generally more positive attitudes towards problem gamblers and treatment seeking.     

Core American values and the structure of antigay prejudice

This work presents a new scale to measure conflicting attitudes toward sexual minorities. This scale parallels existing measures of conflicting racial attitudes (anti-Black and pro-Black attitudes; Katz & Hass, 1988). After constructing and validating measures of antigay and progay attitudes, we tested relationships among core American values with racial and sexual minority attitudes. We examined relations among the Protestant Work Ethic (PWE), Traditional Family Ideology (TFI), and egalitarian values with attitudes toward racial outgroups and sexual minorities. The results revealed that both PWE values and egalitarian values predicted anti-Black attitudes. By contrast, endorsement of egalitarian values, but not PWE values, predicted pro-Black attitudes. Results also revealed a similar but distinct pattern among values and heterosexuals' attitudes toward sexual minorities. TFI, but not egalitarian value endorsement, predicted antigay attitudes, whereas both TFI and egalitarian value endorsement predicted progay attitudes. The implications of these findings are discussed.     

Bayesian Representation of Stochastic Processes under Learning: de Finetti Revisited

A probability distribution governing the evolution of a stochastic process has infinitely many Bayesian representations of the form μ=∫μdλ(θ). Among these, a natural representation is one whose components ( μ's) are ‘learnable’ (one can approximate μ by conditioning μ on observation of the process) and ‘sufficient for prediction’ (μ's predictions are not aided by conditioning on observation of the process). We show the existence and uniqueness of such a representation under a suitable asymptotic mixing condition on the process. This representation can be obtained by conditioning on the tail-field of the process, and any learnable representation that is sufficient for prediction is asymptotically like the tail-field representation. This result is related to the celebrated de Finetti theorem, but with exchangeability weakened to an asymptotic mixing condition, and with his conclusion of a decomposition into i.i.d. component distributions weakened to components that are learnable and sufficient for prediction.

Development and Validation of TQM Implementation Constructs

The contemporary quality management (QM) literature prescribes various quality improvement strategies. However, it lacks scientifically developed and tested constructs that represent an integrative QM philosophy. Moreover, an impact of the prescribed QM strategies on a firm's product quality has not been analyzed. Through a detailed analysis of the literature, this research identifies 12 constructs of integrated QM strategies. Using a survey of 371 manufacturing firms, the constructs are then empirically tested and validated. LISREL 7 is used for this purpose. Finally, a framework to examine the effects of integrated QM strategies on a firm's product quality is suggested. Comparisons between this and two other comprehensive scales of TQM are made.
