Processes of Sexual Orientation Questioning among Heterosexual Women

Because very little is known about heterosexual identity development, this study assesses and describes sexual orientation questioning processes of heterosexual-identified women and offers a comparison of these processes with those employed by their sexual-minority counterparts. Participants included 333 female college students (ages 18–23; M = 19.2): 228 participants primarily identified as “exclusively straight/heterosexual,” and 105 participants indicated a sexual-minority identity. Sixty-seven percent of exclusively heterosexual respondents (n = 154) indicated having thought about or questioned their sexual orientation. The processes by which heterosexual participants described questioning their sexual orientation were coded for the presence of five emergent categories using an inductive thematic coding methodology. These five categories included unelaborated questioning (19%), other-sex experiences (16%), exposure to sexual minorities (26%), assessment of same-sex attraction (48%), and evaluations of same-sex behavior (26%). Several unifying and differentiating themes emerged between sexual orientation groups. Results from this study suggest that contemporary young women's heterosexuality is not necessarily an unexamined identity; indeed, the large majority of young women in this sample were deliberately identifying as heterosexual after contemplating alternative possibilities.     

Radical Social Work in These Contemporary Times

This article explores the educational journey of one man from leaving school in the mid-1970s, at the age of 14, through a period of chaotic drug use, and on to developing his career helping other chaotic drug users back into a “normal” life. Although focused on someone with drug dependency as part of his history, the article exposes issues that potentially underlie the experiences of many learners within working-class communities. In particular, it examines the role of formal and informal education, considers education's ability to liberate or domesticate (Freire, 1972), and examines approaches to learning that support recovery and transformation.     

Adaptive sampling without replacement of clusters

In a common form of adaptive cluster sampling, an initial sample of units is selected by random sampling without replacement and, whenever the observed value of the unit is sufficiently high, its neighboring units are added to the sample, with the process of adding neighbors repeated if any of the added units are also high valued. In this way, an initial selection of a high-valued unit results in the addition of the entire network of surrounding high-valued units and some low-valued “edge” units where sampling stops. Repeat selections can occur when more than one initially selected unit is in the same network or when an edge unit is shared by more than one added network. Adaptive sampling without replacement of networks avoids some of this repeat selection by sequentially selecting initial sample units only from the part of the population not already in any selected network. The design proposed in this paper carries this step further by selecting initial units only from the population, exclusive of any previously selected networks or edge units.     

The Costs of Future Polio Risk Management Policies

Decisionmakers need information about the anticipated future costs of maintaining polio eradication as a function of the policy options under consideration. Given the large portfolio of options, we reviewed and synthesized the existing cost data relevant to current policies to provide context for future policies. We model the expected future costs of different strategies for continued vaccination, surveillance, and other costs that require significant potential resource commitments. We estimate the costs of different potential policy portfolios for low-, middle-, and high-income countries to demonstrate the variability in these costs. We estimate that a global transition from routine immunization with oral poliovirus vaccine (OPV) to inactivated poliovirus vaccine (IPV) would increase the costs of managing polio globally, although routine IPV use remains less costly than routine OPV use with supplemental immunization activities. The costs of surveillance and a stockpile, while small compared to routine vaccination costs, represent important expenditures to ensure adequate response to potential outbreaks. The uncertainty and sensitivity analyses highlight important uncertainty in the aggregated costs and demonstrates that the discount rate and uncertainty in price and administration cost of IPV drives the expected incremental cost of routine IPV vs. OPV immunization.     

Development and Consideration of Global Policies for Managing the Future Risks of Poliovirus Outbreaks: Insights and Lessons Learned Through Modeling

The success of the Global Polio Eradication Initiative promises to bring large benefits, including sustained improvements in quality of life (i.e., cases of paralytic disease and deaths avoided) and costs saved from cessation of vaccination. Obtaining and maintaining these benefits requires that policymakers manage the transition from the current massive use of oral poliovirus vaccine (OPV) to a world without OPV and free of the risks of potential future reintroductions of live polioviruses. This article describes the analytical journey that began in 2001 with a retrospective case study on polio risk management and led to development of dynamic integrated risk, economic, and decision analysis tools to inform global policies for managing the risks of polio. This analytical journey has provided several key insights and lessons learned that will be useful to future analysts involved in similar complex decision-making processes.     

Machismo: Manifestations of a cultural value in the Latin American casino

Casino operations were observed in twelve Latin American countries. Owners, managers, employees, players, and government regulators in each of these countries were interviewed. The concept of machismo is described in its historical and cultural context. It is then used to illuminate casino operations and the mode of play in existence in these casinos.Research activities for this paper were supported by grants from the First Interstate Bank of Las Vegas, Nevada, through the Center for Business Leadership at the University of Nevada, Las Vegas, and from Tottenham and Associates, Gaming Consultants, London, England.     

Validating Benefit and Cost Estimates: The Case of Airbag Regulation

Preregulation estimates of benefits and costs are rarely validated after regulations are implemented. This article performs such a validation for the mandatory automobile airbag requirement. We found that the original 1984 model used to estimate benefits became invalid when 1997 values were input into that 1984 model. However, using a published 1997 cost-effectiveness model, we demonstrate, by replacing the model inputs with the values from 1984, that the 1997 cost-effectiveness ratios, based on real-world crash data and tear-down cost data, are less attractive than what would have been originally anticipated. The three most important errors in the 1984 input values are identified: the overestimation of airbag effectiveness, the overestimation of baseline fatality/injury rates, and the underestimation of manual safety belt use. This case study, which suggests that airbags are a reasonable investment in safety, shows that the regulatory analysis tools do not always produce findings that are biased against health, safety, and environmental regulation. Future validation studies of health, safety, and environmental regulation should focus on validation of benefit and risk estimates, areas where we found significant error, as well as on cost estimates.     

Likelihood Ratio Tests for Fixed Model Terms using Residual Maximum Likelihood

Likelihood ratio tests for fixed model terms are proposed for the analysis of linear mixed models when using residual maximum likelihood estimation. Bartlett-type adjustments, using an approximate decomposition of the data, are developed for the test statistics. A simulation study is used to compare properties of the test statistics proposed, with or without adjustment, with a Wald test. A proposed test statistic constructed by dropping fixed terms from the full fixed model is shown to give a better approximation to the asymptotic χ²-distribution than the Wald test for small data sets. Bartlett adjustment is shown to improve the χ²-approximation for the proposed tests substantially.
