Values and Vegetarianism: An Exploratory Analysis1

The American diet has changed substantially over the last few decades. These changes provide a test for social theory and have substantial effects on the demand for various food products, thus impacting U.S. agriculture. In this paper a rapidly growing dietary choice—vegetarianism—is explored. Prevalence of various forms of vegetarianism is estimated in a representative sample of a suburban population and factors that influence choice of a vegetarian diet are examined. About 7 percent of the sample report they are vegetarians. The prevalence of vegetarianism is not influenced by age, gender, or education, but individuals holding traditional values are less likely to be vegetarian than others. There also is some evidence mat individuals holding altruistic values are more likely than others to be vegetarians.     

The behavioural wedge

When nations fail to agree, can individual citizens make a difference? The third of our post-Copenhagen features is by Jonathan Gilligan, Thomas Dietz, Gerald T. Gardner, Paul C. Stern , and Michael P. Vandenbergh . They look at the effects that voluntary actions by individuals can have, and at the policies that can best encourage such actions.     

On the Utility of Robust and Resampling Procedures1

Abstract Kassab (1990) makes an important methodological contribution by urging the use of robust regression methods in the study of community economic impacts and by indicating the utility of the bootstrap in assessing standard errors in robust regression. By introducing the notion of a contaminating distribution, we reconcile differences between her claim that ordinary least squares (OLS) regression is biased when outliers are present and standard linear model theory that does not make assumptions about the shape of the residual distribution in proving OLS an unbiased estimator. The contaminating distribution provides a framework for rural sociologists to link their statistical assumptions to a substantive understanding of the phenomena being studied. We suggest an alternative regression estimation strategy that may be more robust than the technique she uses. We also discuss an approach to bootstrapping that is more appropriate for macro-level social indicator data than the one she describes. An appendix discusses the software available for implementing these methods.     

Domestic violence beliefs and perceptions among college students

This study builds on current research, investigating the relationships between sociodemographic variables and domestic violence attitudes and beliefs among college students. Data from the Relationship Characteristics Study conducted in 2001, which includes a sample of 1,938 college students, are used to replicate and extend the research of Carlson and Worden (2001, 2005), the developers of the attitudes and beliefs items. In addition, the research portends to analyze factors associated with domestic violence causation endorsement, physical and sexual abuse, stalking, and verbal abuse beliefs, including gender, race and ethnicity, university year, parents' education, family income, parents' marital status, and relationship status. Results are consistent with the rates reported by the item developers. Further, results demonstrate that sociodemographic variables are correlated with physical and sexual abuse and verbal abuse beliefs and causation endorsement.     

The zero-inflated Poisson model and the decayed, missing and filled teeth index in dental epidemiology

For frequency counts, the situation of extra zeros often arises in biomedical applications. This is demonstrated with count data from a dental epidemiological study in Belo Horizonte (the Belo Horizonte caries prevention study) which evaluated various programmes for reducing caries. Extra zeros, however, violate the variance–mean relationship of the Poisson error structure. This extra-Poisson variation can easily be explained by a special mixture model, the zero-inflated Poisson (ZIP) model. On the basis of the ZIP model, a graphical device is presented which not only summarizes the mixing distribution but also provides visual information about the overall mean. This device can be exploited to evaluate and compare various groups. Ways are discussed to include covariates and to develop an extension of the conventional Poisson regression. Finally, a method to evaluate intervention effects on the basis of the ZIP regression model is described and applied to the data of the Belo Horizonte caries prevention study.     

Reshaping Clinical Practice for the New Millennium

In the new millennium, oppression will continue to affect social workers’ clients. This article discusses training clinical practitioners to address oppression. Drawing on poststructural, postmodern, feminist, and social constructivist theories, the article argues that to challenge oppression, clinical practice must address the dialectical relationship between private troubles and public issues while transforming professional relationships that disempower clients. The article describes a second-year MSW clinical practice sequence taught from feminist, poststructuralist, postmodern, and social constructionist perspectives, where students learn to assess the impacts of oppression, discover clients’ strengths, and respond in personal, social, and political contexts.     

THE UNRELENTING SIGNIFICANCE OF MINORITY STATUSES: GENDER,ETHNICITY, AND ECONOMIC ATTAINMENT SINCE AFFIRMATIVE ACTION

Using data from the National Longitudinal Survey of Youth and based on the split-class theory of racial and ethnic discrimination, this research examines the effects of gender, ethnicity, education, family characteristics, and geographic residence over time on economic attainment. While gender and family poverty status had greater impacts on overall economic attainment, results reveal that being an ethnic minority is significantly associated with lower wages. Moreover, results reveal that the disadvantage to racial and ethnic minorities has expanded over time or becomes more important at advanced ages. The results lend support to split-class theory and the arguments of Charles V. Willie that race/ethnicity has become a more important, rather than becoming less important indicator of poverty and income. Further, the results refute the notions that Affirmative Action has accomplished its goals or that it leads to reverse discrimination against White males.
