Constructing Whiteness in Health Disparities Research
There is a long tradition within the United States of constructing whiteness (the racial subject) against racialized others (the racial object) and in the process displacing the focus of critical analysis. Here we turn our lens to the often invisible--or at least underinterrogated--concept of whiteness within the context of the literature on racial disparities in health. Specifically, we examine how whiteness is constructed in the active literature documenting and interpreting racial disparities in health and the implications of these constructions for efforts to eradicate inequalities in health. We draw on the concepts of racial formation and racial projects that emphasize the fluidity, mutability, and historically constructed nature of race, as well as the social and political processes through which racial categories are created and transformed. A racial project is simultaneously an interpretation, representation, or explanation of racial dynamics. In particular, we apply Winant\u27s concept (1997) of racial projects to examine the construction of whiteness in ongoing dialogues about race and racial disparities in health. We consider the ways that varying constructions of whiteness enter into, influence, and are influenced by discussions of racial disparities in health, and the role of those constructions in the reproduction or disruption of racial categories and the inequitable distribution of resources along racial lines

Hypertension: Development of a prediction model to adjust self-reported hypertension prevalence at the community level
Abstract
Background
Accurate estimates of hypertension prevalence are critical for assessment of population health and for planning and implementing prevention and health care programs. While self-reported data is often more economically feasible and readily available compared to clinically measured HBP, these reports may underestimate clinical prevalence to varying degrees. Understanding the accuracy of self-reported data and developing prediction models that correct for underreporting of hypertension in self-reported data can be critical tools in the development of more accurate population level estimates, and in planning population-based interventions to reduce the risk of, or more effectively treat, hypertension. This study examines the accuracy of self-reported survey data in describing prevalence of clinically measured hypertension in two racially and ethnically diverse urban samples, and evaluates a mechanism to correct self-reported data in order to more accurately reflect clinical hypertension prevalence.
Methods
We analyze data from the Detroit Healthy Environments Partnership (HEP) Survey conducted in 2002 and the National Health and Nutrition Examination (NHANES) 2001–2002 restricted to urban areas and participants 25 years and older. We re-calibrate measures of agreement within the HEP sample drawing upon parameter estimates derived from the NHANES urban sample, and assess the quality of the adjustment proposed within the HEP sample.
Results
Both self-reported and clinically assessed prevalence of hypertension were higher in the HEP sample (29.7 and 40.1, respectively) compared to the NHANES urban sample (25.7 and 33.8, respectively). In both urban samples, self-reported and clinically assessed prevalence is higher than that reported in the full NHANES sample in the same year (22.9 and 30.4, respectively). Sensitivity, specificity and accuracy between clinical and self-reported hypertension prevalence were ‘moderate to good’ within the HEP sample and ‘good to excellent’ within the NHANES sample. Agreement between clinical and self-reported hypertension prevalence was ‘moderate to good’ within the HEP sample (kappa =0.65; 95% CI = 0.63-0.67), and ‘good to excellent’ within the NHANES sample (kappa = 0.75; 95%CI = 0.73-0.80). Application of a ‘correction’ rule based on prediction models for clinical hypertension using the national sample (NHANES) allowed us to re-calibrate sensitivity and specificity estimates for the HEP sample. The adjusted estimates of hypertension in the HEP sample based on two different correction models, 38.1% and 40.5%, were much closer to the observed hypertension prevalence of 40.1%.
Conclusions
Application of a simple prediction model derived from national NHANES data to self-reported data from the HEP (Detroit based) sample resulted in estimates that more closely approximated clinically measured hypertension prevalence in this urban community. Similar correction models may be useful in obtaining more accurate estimates of hypertension prevalence in other studies that rely on self-reported hypertension.http://deepblue.lib.umich.edu/bitstream/2027.42/112834/1/12913_2011_Article_2187.pd
Modeling the SS 433 Jet Bends
We fit Chandra HETGS data obtained for the unusual X-ray binary SS 433. While
line strengths and continuum levels hardly change, the jet Doppler shifts show
aperiodic variations that probably result from shocks in interactions with the
local environment. The X-ray and optical emission line regions are found to be
related but not coincident as the optical line emission persists for days while
the X-ray emission lines fade in less than 5000 s. The X-ray spectrum of the
blue-shifted jet shows over two dozen emission lines from plasma at a variety
of temperatures. The emission measure distribution derived from the spectrum
can be used to test jet cooling models.Comment: 4 pages, 3 figure, presented at the conference on "Hign Energy

How much are built environments changing, and where?: Patterns of change by neighborhood sociodemographic characteristics across seven U.S. metropolitan areas
Investments in neighborhood built environments could increase physical activity and overall health. Disproportionate distribution of these changes in advantaged neighborhoods could inflate health disparities. Little information exists on where changes are occurring. This paper aims to 1) identify changes in the built environment in neighborhoods and 2) investigate associations between high levels of change and sociodemographic characteristics. Using Geographic Information Systems, neighborhood land-use, local destinations (for walking, social engagement, and physical activity), and sociodemographics were characterized in 2000 and 2010 for seven U.S. cities. Linear and change on change models estimated associations of built environment changes with baseline (2000) and change (2010–2000) in sociodemographics. Spatial patterns were assessed using Global Moran’s I to measure overall clustering of change and Local Moran’s I to identify statistically significant clusters of high increases surrounded by high increases (HH). Sociodemographic characteristics were compared between HH cluster and other tracts using Analysis of Variance (ANOVA). We observed small land-use changes but increases in the destination types. Greater increases in destinations were associated with higher percentage non-Hispanic whites, percentage households with no vehicle, and median household income. Associations were present for both baseline sociodemographics and changes over time. Greater increases in destinations were associated with lower baseline percentage over 65 but higher increases in percentage over 65 between 2000 and 2010. Global Moran’s indicated changes were spatially clustered. HH cluster tracts started with a higher percentage non-Hispanic whites and higher percentage of households without vehicles. Between 2000 and 2010, HH cluster tracts experienced increases in percent non-Hispanic white, greater increases in median household income, and larger decreases in percent of households without a vehicle. Changes in the built environment are occurring in neighborhoods across a diverse set of U.S. metropolitan areas, but are patterned such that they may lead to increased health disparities over time
