Changing Social Work Students’ Perceptions of the Role of Government in a Policy Class

Understanding student political attitudes—feelings about government and perceptions of its role—has long been of interest to social scientists. One factor that may influence political attitudes is belief in a just world, a complex psychological construct well established in the literature. Our study explores changes in social work students’ perception of a supportive role of government and their beliefs in a just world after one policy course using a pretest and posttest design. Student perceptions changed toward a more supportive government role, but there was no significant change for belief in a just world. The study contributes to empirical evaluation of the social work education policy class in terms of the Council on Social Work Education competencies.     

Dependency or Self-Reliance? The Contradictory Case of Work in UK Small Business Families

The focus of this article is a relatively neglected area of social and family policy: its relationship with small business. Economic policy makers have encouraged enterprise, particularly in the form of small business, as a solution to problems of competitiveness and economic growth. The article uncovers what an enterprise culture actually means for some of those families who first embarked upon business ownership in the 1980s in the UK Using data from a qualitative study, it contends that, in contradiction to the enterprise rhetoric, for micro-businesses owners and their families, values of self-reliance and dependency often are found as opposite characteristics necessary for the success of a small business. A recent survey of micro-businesses in contrasting British regional economies suggests that such experiences are likely to be found amongst a substantial proportion of micro-businesses.     

Business Legitimacy among Business Students in the United States, Great Britain, and South Africa

This study compares attitudes toward business legitimacy in three countries. Positive attitudes toward business legitimacy exist when there is a congruence between organizational activities and societal expectations. Businesses are concerned about the extent to which negative attitudes toward business legitimacy will lead to increased government regulation. The results suggest that business students in all three countries are similar in their attitudes toward business legitimacy; however, blacks have more negative attitudes toward business legitimacy than do whites. This study resulted in the validation of a scale that can be used to measure attitudes toward business legitimacy on a cross-cultural basis. Business legitimacy is a major concern in South Africa as the predominately white business community seeks to give the emerging black majority a stake in the existing economic system. This revised version was published online in August 2006 with corrections to the Cover Date.     

(Dis)respecting versus (Dis)liking: Status and Interdependence Predict Ambivalent Stereotypes of Competence and Warmth

As Allport (1954) implied, the content of stereotypes may be systematic, and specifically, ambivalent. We hypothesize two clusters of outgroups, one perceived as incompetent but warm (resulting in paternalistic prejudice) and one perceived as competent but not warm (resulting in envious prejudice). Perceived group status predicts perceived competence, and perceived competition predicts perceived (lack of) warmth. Two preliminary surveys support these hypotheses for 17 outgroups. In-depth analyses of prejudice toward particular outgroups support ambivalent prejudice: Paternalistic prejudice toward traditional women, as well as envious prejudice toward career women, results in ambivalent sexism (Glick & Fiske, 1996). Envious prejudice toward Asians results in perceived competence but perceived lack of social skills. Ambivalent content reflects systematic principles.     

Three Models of Conflict Resolution: Effects on Intergroup Expectancies and Attitudes

Gordon Allport (1960) once noted that there are many different approaches to conflict resolution, but that few empirical studies have been conducted to examine their effectiveness. This experiment was designed to evaluate the distributive bargaining, integrative bargaining, and interactive problem solving models of conflict resolution, using intergroup expectancies and attitudes as dependent measures. Jewish and Arab students were paired into mixed-ethnicity dyads to discuss the Israeli-Palestinian dispute about Jerusalem according to one of the three models. It was hypothesized that dyad members using the interactive problem solving model would become the least pessimistic about the conflict, and would show the greatest positive change in their attitudes toward members of the other ethnic group. The results support these predictions, and help to make up for the paucity of research on the assessment of conflict resolution strategies.     

A Demographic Model of Measles Epidemics

Liverpool, U.K., 1863--1900, has been used as a model to explore the interaction between measles epidemics and the population dynamics in an overcrowded community with inadequate nutrition using a non-linear model which allows the estimation of certain underlying demographic parameters. The results are consistent with a system that is driven by an oscillation in the transmission parameter that is compounded of an oscillation in autumn temperatures (at the resonant frequency of the system, 2.4 years) and, secondarily, by an oscillation in wheat prices (wavelength = 5.3 years, twice that of the epidemics).     

Distribution of Exposure Concentrations and Doses for Constituents of Environmental Tobacco Smoke

The ultimate goal of the research reported in this series of three articles is to derive distributions of doses of selected environmental tobacco smoke (ETS)-related chemicals for nonsmoking workers. This analysis uses data from the 16-City Study collected with personal monitors over the course of one workday in workplaces where smoking occurred. In this article, we describe distributions of ETS chemical concentrations and the characteristics of those distributions (e.g., whether the distribution was log normal for a given constituent) for the workplace exposure. Next, we present population parameters relevant for estimating dose distributions and the methods used for estimating those dose distributions. Finally, we derive distributions of doses of selected ETS-related constituents obtained in the workplace for people in smoking work environments. Estimating dose distributions provided information beyond the usual point estimate of dose and showed that the preponderance of individuals exposed to ETS in the workplace were exposed at the low end of the dose distribution curve. The results of this analysis include estimations of hourly maxima and time-weighted average (TWA) doses of nicotine from workplace exposures to ETS (extrapolated from 1 day to 1 week) and doses derived from modeled lung burdens of ultraviolet-absorbing particulate matter (UVPM) and solanesol resulting from workplace exposures to ETS (extrapolated from 1 day to 1 year).
