Environmental gas displacement: three accidental deaths in the workplace

The authors describe three accidental deaths resulting from occupational hazards involving environmental gas alterations. One involved the displacement of oxygen caused by leakage of liquid nitrogen during the installation of a magnetic resonance imaging system. Two involved elevated environmental carbon dioxide concentrations: dry ice sublimation in a walk-in refrigerator in a research laboratory, and activation of a carbon dioxide fire alarm-extinguisher system by a woman locked in a bank vault. The autopsy findings, scene investigations, and certifications of these deaths, as related to the mechanisms of death, are discussed.     

Factors Associated with Physician Discussion of Health Behaviors with Adolescents

Behaviors developed in adolescence influence health later in life. The purpose of this study was to investigate the frequency of health care provider's discussion of health behaviors with overweight and non-overweight adolescents and identify demographic and health behaviors related to exercise, hours of television viewing, and weight issues associated with these discussions. A Cross sectional survey of urban adolescents was conducted. Trained interviewers administered surveys over a three month period in 2001 at an urban academic pediatric and adolescent clinic. The 252 adolescents surveyed had a mean age of 15 with 49% categorized as being at risk for overweight/overweight and 51% as normal weight using the CDC percentiles for BMI. While 16% of the adolescents reported that their physician or nurse discussed the amount of television they watched, rates of discussion related to exercise (58%), and weight (54%) were much higher. In multivariate analyses, health care provider discussions with adolescents regarding exercise were more common for overweight (O.R.=2.42, 95% C.I. [1.28–4.57]) and at risk for overweight (O.R.=1.98, 95% C.I. [1.03–3.81]) adolescents, whereas physician discussion of television viewing was not associated with weight. Discussions of weight were more common for female (O.R.=2.18, 95% C.I. [1.21–3.95]), African-American (O.R.=2.53, 95% C.I. [1.40–4.57]), and overweight (O.R.=3.92, 95% C.I. [1.97–7.81]) adolescents. Even after adjusting for weight, race and gender strongly influenced the frequency of discussions about weight in physician offices. Although health care providers frequently address weight and exercise with adolescents, more discussions related to sedentary behaviors such as television viewing may be warranted to address adolescent obesity.Received PhD in Epidemiology from University of California, San Diego.

The Skinny on Body Dissatisfaction: A Longitudinal Study of Adolescent Girls and Boys

The present study tested whether theoretically derived risk factors predicted increases in body dissatisfaction and whether gender moderated these relations with data from a longitudinal study of 428 adolescent girls and boys because few prospective studies have examined these aims, despite evidence that body dissatisfaction increases risk for various psychiatric disturbances. Body dissatisfaction showed significant increases for girls and significant decreases for boys during early adolescence. For both genders, parental support deficits, negative affectivity, and self-reported dietary restraint showed significant relations to future increases in body dissatisfaction. Ideal body internalization and body mass index did not demonstrate significant relations to future increases in body dissatisfaction; peer support deficits showed a marginal relation to this outcome. Gender did not moderate these relations, despite adequate power to detect interactive effects.

Research in Context: Measuring Value Change

Abramson and Inglehart find a significant trend toward postmaterialist values in Western Europe, which they argue is largely driven by the gradual processes of generational replacement. Clarke, Dutt, and Rapkin argue that this trend is a methodological artifact of the wording of Inglehart's four-item measure of materialist/ postmaterialist values. They claim that because this battery does not include a question about unemployment, in periods of high unemployment respondents tend to choose postmaterialist goals. The long-term trend toward postmaterialism in Western Europe, they argue, results from rising levels of unemployment during the past two decades. Abramson and Inglehart point out that increases in inflation have a short-term impact on decreasing postmaterialism, but maintain that the positive relationship between unemployment and postmaterialism is spurious. As this analysis shows, Clarke, Dutt, and Rapkin find a positive relationship between unemployment and postmaterialism by building a model that has little theoretical justification and that is not robust to changes in specification. As this analysis demonstrates, unemployment is actually linked with support for materialist goals, and the trend toward post-materialism is robust in the face of alternative time frames, models, and specifications. The weight of the evidence demonstrates that the long-term trend toward postmaterialism in Western Europe is driven by generational replacement.     

Labor market experiences of low-income black women in middle-class suburbs: Evidence from a survey of gautreaux program participants

This article reports on a highly unusual experiment in racial and economic integration, the Gautreaux program. This program helps black families who are either current or former residents of public housing move into subsidized housing in Chicago and its suburbs. Surveying a random sample of 332 participants, we find that suburban movers are significantly more likely to have a job post-move than city movers, even among those who had never had a job before moving. Multivariate analysis shows that these differences are significant even after controlling for respondents' previous work history, human capital, and personal characteristics. These results suggest that low-income urban blacks experience significant gains in employment by moving to middle-class suburbs. Thus, housing assistance may be an effective alternative to traditional welfare-to-work programs.     

Distributive and Procedural Justice in Seven Nations

The paper examines the impact of distributive justice and procedural justice variables on judgments in seven countries (Bulgaria, France, Hungary, Poland, Russia, Spain, and the United States). Subjects were presented with each of two experimental vignettes: one in which the actor unsuccessfully appeals being fired from his job and one in which the actor unsuccessfully goes to an employment agency to seek a job; they were asked to rate the justness of the outcome and how fairly the actor had been treated. The vignettes manipulated deservingness and need of the actor (distributive justice factors) and impartiality and voice in the hearing (procedural justice factors). Four hypotheses were tested: first, a distributive justice hypothesis that deservingness would be more important than need in these settings; second, a procedural justice hypothesis that the importance of voice and impartiality vary depending on the nature of the encounter and the forum in which it is resolved; third, because of their recent socialist experience, Central and Eastern European respondents make greater use of need information and less use of deservingness information than Western respondents; and fourth, that distributive justice and procedural justice factors interact. The distributive justice hypothesis is supported in both vignettes. The procedural justice hypothesis receives some support. Impartiality is more important in the first vignette and voice is more important in the second vignette. The interaction hypothesis was not supported in the first vignette, but does receive some support in the second vignette. The cultural hypothesis is not supported in either vignette. The implications for distributive and procedural justice research are discussed.
