World War II and Its Effect on the Sex Differential in Arrests: An Empirical Test of the Sex-Role Equality and Crime Proposition*

A common explanation for the decrease in the sex differential in arrests during World War II attributes it to a change in female sex-role behavior. Because of the wartime equalization of sex roles, particularly of expanding occupational roles of women, female arrest rates began to approach male rates. Two alternative explanations appear equally plausible: (1) changes in the sex-age structure of the population at risk and (2) changes in official reactions to female "sex offenders" over the prewar to wartime period, as reflected in the differentiation in types of crimes for which males and females were arrested during World War II. The analysis examines these two alternative explanations, and finds that: (a) by simply correcting for the sex-age structure of the population, the narrowing of the sex differential is reduced considerably; and (b) by taking into account type of crime, and specifically by omitting offense categories that reflect the paternalism and double standard of sexual morality in society, the narrowing of the sex differential disappears. Finally, the predicted special effects of World War II on female arrests for property crimes did not materialize.

Modeling Rabbit Responses to Single and Multiple Aerosol Exposures of Bacillus anthracis Spores

Survival models are developed to predict response and time‐to‐response for mortality in rabbits following exposures to single or multiple aerosol doses of Bacillus anthracis spores. Hazard function models were developed for a multiple‐dose data set to predict the probability of death through specifying functions of dose response and the time between exposure and the time‐to‐death (TTD). Among the models developed, the best‐fitting survival model (baseline model) is an exponential dose–response model with a Weibull TTD distribution. Alternative models assessed use different underlying dose–response functions and use the assumption that, in a multiple‐dose scenario, earlier doses affect the hazard functions of each subsequent dose. In addition, published mechanistic models are analyzed and compared with models developed in this article. None of the alternative models that were assessed provided a statistically significant improvement in fit over the baseline model. The general approach utilizes simple empirical data analysis to develop parsimonious models with limited reliance on mechanistic assumptions. The baseline model predicts TTDs consistent with reported results from three independent high‐dose rabbit data sets. More accurate survival models depend upon future development of dose–response data sets specifically designed to assess potential multiple‐dose effects on response and time‐to‐response. The process used in this article to develop the best‐fitting survival model for exposure of rabbits to multiple aerosol doses of B. anthracis spores should have broad applicability to other host–pathogen systems and dosing schedules because the empirical modeling approach is based upon pathogen‐specific empirically‐derived parameters.     

LGBT Faculty,Research, and Researchers: Risks and Rewards

ABSTRACT

Self-identified lesbian, gay, bisexual, and transgender (LGBT) faculty along with heterosexuals with scholarly interests in these populations can face heterosexism, heterocentrism, homophobia, and hostility within and outside of social work programs. This article describes the risks and rewards of being an LGBT faculty based on the experiences of the authors. Myths and realities relating to coming out, promotion, and funding are discussed, along with the pitfalls of tokenism and the stress of being an LGBT faculty of color. Ways to endure and even thrive in spite of these potentially formidable burdens are also described.     

Practice and Research in Career Counseling and Development—2000

The authors summarize the career counseling and development literature that appeared during 2000 in refereed journals, book chapters, and full‐length books. The review of literature is divided into 5 major categories: (a) theoretical and conceptual advances, (b) career counseling and development of identified populations, (c) assessment in career counseling and development, (d) career counseling programs and interventions, and (e) resources for the professional development of career counselors and vocational psychologists.     

Unions,seniority, and public choice

This paper examines the implications of granting a seniority-based system to a union whose behavior is determined by a median voter rule. It is shown that the union will negotiate a sequence of wages that will contract union employment in each period. The model then is extended to include an active role for the firm. It is shown that when the firm has the opportunity to resist unionization, the union will not allow union employment to fall below some lower bound. This lower bound is then a steady-state equilibrium.     

Social work leadership: reflections on a student-led conference

Servant leadership encompassing collaborative mentorship, empowerment and a faculty/student partnership approach contributed to the success of an international social work conference led by undergraduate students and supported by faculty members. Using a retrospective case study design, data were collected from social work undergraduate students on the conference planning committee, reflections of faculty, and documentation from conference evaluations. This paper explores the findings of the conference planning experience and considers how social work principles can foster student engagement and build capacity for undergraduate students to practice leadership skills within higher educational settings.     

The division of union rents

In this paper, a median voter model that recognizes the trade-off between higher wages and lower levels of employment is presented. It is argued that a seniority-based layoff rule creates the opportunity for mutually beneficial side-payments between older and younger workers. As a result, older workers reap more of the rents of unionization than do younger workers. The resulting distribution of union rents is found to be consistent with existing empirical evidence. We would like to thank Mike Baye and Gene Grossman for most useful comments on earlier versions of this paper. Any remaining errors, of course, are solely our responsibility.
