Modeling offset policy in government procurement

This paper develops an empirical model to examine offset arrangements in government procurement. Offsets are non-standard contracts that governments use to extract rents from multinational corporations. Previous contributions focus on the transaction cost Taylor (2003); Udis and Maskus (1991); Liesch (1991) and bundling Hall and Markowski (1996) rationale for offsets. These studies are meaningful, but are devoid of quantitative models needed to test the theoretical claims. This study fills part of the gap in the literature. The results suggest that while economic variables (transaction costs, price, quality) are part of the offset selection process, political economy variables (security alliances and rent-seeking) tend to exert more influence on policy.     

Potential Health Effects of Light-Duty Diesel Exhaust

The purpose of this paper is to review briefly the evidence for potential human health effects that may result from increased dieselization of the nation's light-duty vehicle fleet. An effort is made to put the potential effects into perspective, both with regard to projected excess cancer deaths, should diesel exhaust be carcinogenic to humans, and in relation to past use of vehicles using leaded gasoline. Certain related research needs are highlighted. Available data concerning the relationship between diesel emissions, ambient air quality, and human health are summarized. On the basis of exposure estimates and relative potency factors, the authors conclude that the best estimate of the number of excess annual U.S. lung cancer deaths as a result of lifetime exposure to light-duty diesel particulate under 1990 conditions is between 80 and 1500. Available data suggest that the carcinogenic hazard of exhaust from vehicles burning leaded gasoline may be an order of magnitude greater, on a per mile basis, than that of diesel engines. The hazard of emissions from diesel are, in turn, probably an order of magnitude greater than that of gasoline engines with catalytic converters burning unleaded gasoline. Important research needs identified by the authors include determining whether diesel exhaust is in fact a human carcinogen, studying the effect of atmospheric chemical transformation of organics in diesel exhaust on the toxicity of the exhaust, making a better determination of the relative carcinogenicity of diesel and gasoline exhausts, and determining whether exposure to diesel exhaust contributes to the development or exacerbation of chronic lung disease or of respiratory illness, especially in the very young and the aged.     

Effects of Context and Feelings on Perceptions of Genetically Modified Food

Recently, there has been a surge of interest in the role of feelings in framing perceptions and decisions about risk, yet no study has specifically examined the impact of feelings on perceptions/judgments about biotechnology. This exploratory study investigated current perceptions of genetically modified (GM) food to examine (1) the effects of context (making judgments about GM food at the same time as rating other current areas of concern), and (2) the effect of feelings of dread (integral affect) and background feelings of stress (negative incidental affect) on risk judgments about GM food. An established psychometric method (semantic differential task) used with a sample of 126 adults (recruited "topic-blind," mostly from a student population) showed that, when rated in the context of other current concerns such as human cloning and Creutzfeldt-Jakob disease (CJD), there was less concern about GM food than might have been anticipated. Participants were recruited "topic-blind" in order to ensure that they were unaware that the focus of the research was on GM food specifically (and thus preventing biased recruitment to the study). Relative to 19 other current concerns GM food was "not dreaded," not viewed as "unethical," was judged as "controllable," and was seen as the least "risky" of all the issues studied. GM food was viewed as a "hot topic," a new risk, and as relatively unnatural (although it was not the highest rated concern on this scale). Ratings of risks across concerns by individuals experiencing high levels of negative incidental affect (stress) did not differ significantly from those reporting low stress.     

Medical Decision Making and Elective Surgery: The Case of Hysterectomy

Review and analyses of three sources of data are presented indicating that 25% of hysterectomies are elective. Annual mortality associated with elective hysterectomy is estimated to be 319, or about 12,122 woman years. Cost-benefit analyses of mortality, life expectancy, morbidity, psychological sequelae, as well as dollar expenditures, reveal high costs and relatively limited benefits. Explanations for this apparent anomaly in decision making are explored and include economic incentives, system structure, sexism, and cancer prophylaxis. Principles of risk perception are discussed in terms of potential biases associated with the cancer prophylaxis motive. It is suggested that physicians' judgements of risk may be more salient to the decision process than those of prospective patients.     

Impact of Religiosity on the Sexual Risk Behaviors of Young Men Who Have Sex With Men

Young men who have sex with men (YMSM), particularly Black YMSM, bear a disproportionate burden of new human immunodeficiency virus (HIV) infections in the United States. Several studies support the positive and protective role of religion in health and the prevention of morbidity and mortality. However, little empirical research has been conducted looking at religion with the context of YMSM and HIV prevention. We examined the impact of religious attendance and faithfulness on sexual risk among a community-based sample of 450 YMSM in Chicago ages 16 to 20. Participants were mostly racial/ethnic minorities, that is, Black (53.4%) and Latino (19.9%). Multivariate logistic regression indicated that faithfulness in combination with frequent formal religious attendance was associated with a decrease in reported number of unprotected anal sex acts, including unprotected receptive anal sex with male partners. These association trends were also found for the Black YMSM in our sample, suggesting that religious involvement and faithfulness is a potential protective factor for the acquisition of HIV among this high-risk population.     

Sex and cultural differences in the acceptance of functional foods: a comparison of American, Canadian, and French college students

OBJECTIVE: Functional foods (FF)--foods containing nutritional supplements in addition to natural nutrients--have an increasing presence in the marketplace. Expanding on previous research, the authors investigated college students' acceptance of FF. PARTICIPANTS: In September--March 2004, 811 undergraduates in Canada, the United States, and France participated in the study. METHODS: A self-administered questionnaire measured students' general food attitudes and beliefs as well as FF-related knowledge, attitudes, beliefs, and purchase intention. RESULTS: Overall, participants slightly favored FF over traditional foods. However, although most respondents associated FF with positive health benefits, many remained dubious of currently available FF information. In terms of culture and sex, the authors found small but significant divergences in FF knowledge, attitudes, and behaviors. CONCLUSIONS: Stronger labeling and education efforts may increase cross-cultural acceptance of FF by college students.     

State Income Inequality and Presidential Election Turnout and Outcomes*

Objective. This study examines the links among income inequality, voter turnout, and electoral choice at the state level in recent presidential elections. Methods. We introduce two new state‐level ecological data sets, estimated annual Gini coefficients of income inequality from 1969 to 2004 and a measure of income segregation across Census tracts within states in 1999. We test for associations among inequality, turnout, and party preference with cross‐sectional, fixed‐effects, and multilevel analyses. Results. The cross‐sectional effect of inequality on voter turnout and electoral choice is ambiguous. However, a fixed‐effects analysis links higher income inequality to lower voter turnout and also to a stronger Democratic vote. Multilevel results indicate that higher levels of economic segregation likewise are associated with depressed turnout, after controlling for individual voter characteristics and for state‐level income.     

Occupational Race Segregation,Globalization, and White Advantage: White-Black Earnings Inequality in U.S. Metropolitan Areas

Addressing the need to systematically assess the materialist foundations of color-blind racism, we use insights from critical race theory to investigate the metropolitan-level racial inequality at the turn of the century. Namely, we examine the association between occupational race segregation and white advantage (i.e., white-black earnings inequality) for men and women in 202 U.S. metropolitan statistical areas in the year 2000. We find that occupational race segregation exacerbates white advantage for both male and female workers, supporting the tenets of the materialist conception of color-blind racism. We also consider how processes of globalization and labor market transformation impact white advantage. Our findings indicate that global capital increases white advantage for males, whereas foreign direct investment and casualization serve to decrease it. They also indicate that exports decrease white advantage for females, whereas percent foreign born increases it.     

Prevalence of Depression and Anxiety Among Bisexual People Compared to Gay,Lesbian, and Heterosexual Individuals:A Systematic Review and Meta-Analysis

Over the past decade, evidence has accumulated to suggest that bisexual people experience higher rates of poor mental health outcomes compared to both heterosexual and gay/lesbian individuals. However, no previous meta-analyses have been conducted to establish the magnitude of these disparities. To address this research gap, we conducted a systematic review and meta-analysis of studies that reported bisexual-specific data on standardized measures of depression or anxiety. Of the 1,074 full-text articles reviewed, 1,023 were ineligible, predominantly because they did not report separate data for bisexual people (n = 562 studies). Ultimately, 52 eligible studies could be pooled in the analysis. Results indicate that across both outcomes, there is a consistent pattern of lowest rates of depression and anxiety among heterosexual people, while bisexual people exhibit higher or equivalent rates in comparison to lesbian/gay people. On the basis of empirical and theoretical literature, we propose three interrelated contributors to these disparities: experiences of sexual orientation-based discrimination, bisexual invisibility/erasure, and lack of bisexual-affirmative support. Implications for interventions to improve the health and well-being of bisexual people are proposed.     

Estimating Quality of Life and Place with Location Theory: The McBucks Index

This paper explores the changes in inequality and welfare between EU regions at the NUTS 3 level over the 2003–2011 period. Changes in absolute and relative inequalities are broken down into components explaining the effects of population change, re-ranking of regions and income growth between regional per capita incomes. Each component of inequality change is further decomposed by subgroup, revealing the contributions arising from changes within subgroups and from changes between subgroups. The decomposition of the change in absolute inequality is used to develop a decomposition of the change in welfare between EU regions.
