The Political Economy of US Military Spending
The causes of the dramatic rise in military spending in the post-war era have been the subject of much political and academic controversy. No extant formulation seems to provide a compelling explanation of the dynamics involved in the levels of, and rates of change in, such spending. In light of this, the authors develop a new model, based mainly on a political-business cycle argument, to account for these dynamics. The basic proposition in this model is that variations in national defense spending arise from political considerations which are related to real and desired conditions within the national economy. Applying this model to the experience of the United States 1948-1976, the authors show that it has a large measure of empirical validity. If one removes the effects of war-time mobilization, it is clear that for the United States the principal driving forces in military spending dynamics were (1) the perceived utility of such spending in stabilizing aggregate demand, (2) the political or electoral value of the perceived economic effects arising out of such spending, and (3) the pressures of institutional-constituency demands.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68958/2/10.1177_002234337901600202.pd
Assessment of solar shading strategies in low-income tropical housing: the case of Uganda
Developing countries in tropical and subtropical areas will be the worst hit by climate change. Very little research has been done to assess the impact of climate change on thermal comfort in low-income housing in these regions. The effects of solar shading strategies and solar absorptance properties of walls and roofs on thermal comfort in Ugandan low-income housing are studied in this paper. Various shading strategies including curtains, roof and window overhangs, veranda and trees as well as effects of painting on solar heat gain and thermal comfort are modelled using EnergyPlus software. An adaptive approach for naturally ventilated buildings defined by the European Committee for Standardization standard BS EN 15251:2007 is used to assess the conditions. According to the results, solar shading is less effective in meeting thermal comfort requirements and it should be used in conjunction with other strategies to achieve desirable results. White painting, in contrast, significantly improved the conditions and significantly reduced the risk of overheating. Solar shading proved to be effective during the hottest periods of the year, reducing the risk of extreme overheating by up to 52%
Non-hispanic whites have higher risk for pulmonary impairment from pulmonary tuberculosis
<p>Abstract</p> <p>Background</p> <p>Disparities in outcomes associated with race and ethnicity are well documented for many diseases and patient populations. Tuberculosis (TB) disproportionately affects economically disadvantaged, racial and ethnic minority populations. Pulmonary impairment after tuberculosis (PIAT) contributes heavily to the societal burden of TB. Individual impacts associated with PIAT may vary by race/ethnicity or socioeconomic status.</p> <p>Methods</p> <p>We analyzed the pulmonary function of 320 prospectively identified patients with pulmonary tuberculosis who had completed at least 20 weeks standard anti-TB regimes by directly observed therapy. We compared frequency and severity of spirometry-defined PIAT in groups stratified by demographics, pulmonary risk factors, and race/ethnicity, and examined clinical correlates to pulmonary function deficits.</p> <p>Results</p> <p>Pulmonary impairment after tuberculosis was identified in 71% of non-Hispanic Whites, 58% of non-Hispanic Blacks, 49% of Asians and 32% of Hispanics (<it>p </it>< 0.001). Predictors for PIAT varied between race/ethnicity. PIAT was evenly distributed across all levels of socioeconomic status suggesting that PIAT and socioeconomic status are not related. PIAT and its severity were significantly associated with abnormal chest x-ray, <it>p </it>< 0.0001. There was no association between race/ethnicity and time to beginning TB treatment, <it>p </it>= 0.978.</p> <p>Conclusions</p> <p>Despite controlling for cigarette smoking, socioeconomic status and time to beginning TB treatment, non-Hispanic White race/ethnicity remained an independent predictor for disproportionately frequent and severe pulmonary impairment after tuberculosis relative to other race/ethnic groups. Since race/ethnicity was self reported and that race is not a biological construct: these findings must be interpreted with caution. However, because race/ethnicity is a proxy for several other unmeasured host, pathogen or environment factors that may contribute to disparate health outcomes, these results are meant to suggest hypotheses for further research.</p
Association between community health center and rural health clinic presence and county-level hospitalization rates for ambulatory care sensitive conditions: an analysis across eight US states
<p>Abstract</p> <p>Background</p> <p>Federally qualified community health centers (CHCs) and rural health clinics (RHCs) are intended to provide access to care for vulnerable populations. While some research has explored the effects of CHCs on population health, little information exists regarding RHC effects. We sought to clarify the contribution that CHCs and RHCs may make to the accessibility of primary health care, as measured by county-level rates of hospitalization for ambulatory care sensitive (ACS) conditions.</p> <p>Methods</p> <p>We conducted an ecologic analysis of the relationship between facility presence and county-level hospitalization rates, using 2002 discharge data from eight states within the US (579 counties). Counties were categorized by facility availability: CHC(s) only, RHC(s) only, both (CHC and RHC), and neither. US Agency for Healthcare Research and Quality definitions were used to identify ACS diagnoses. Discharge rates were based on the individual's county of residence and were obtained by dividing ACS hospitalizations by the relevant county population. We calculated ACS rates separately for children, working age adults, and older individuals, and for uninsured children and working age adults. To ensure stable rates, we excluded counties having fewer than 1,000 residents in the child or working age adult categories, or 500 residents among those 65 and older. Multivariate Poisson analysis was used to calculate adjusted rate ratios.</p> <p>Results</p> <p>Among working age adults, rate ratio (RR) comparing ACS hospitalization rates for CHC-only counties to those of counties with neither facility was 0.86 (95% Confidence Interval, CI, 0.78–0.95). Among older adults, the rate ratio for CHC-only counties compared to counties with neither facility was 0.84 (CI 0.81–0.87); for counties with both CHC and RHC present, the RR was 0.88 (CI 0.84–0.92). No CHC/RHC effects were found for children. No effects were found on estimated hospitalization rates among uninsured populations.</p> <p>Conclusion</p> <p>Our results suggest that CHCs and RHCs may play a useful role in providing access to primary health care. Their presence in a county may help to limit the county's rate of hospitalization for ACS diagnoses, particularly among older people.</p
Indicators for tracking programmes to strengthen health research capacity in lower- and middle-income countries: a qualitative synthesis
Maintaining the Environmental–Racial Order in Northern New Mexico
The environmental - racial order in northern New Mexico is maintained through a process of racial triangulation in which Anglos, Native Americans, and Hispanos are valued relative to one another along axes of environmental stewardship and victimization (Kim C J, 1999, "The racial triangulation of Asian Americans" Politics and Society 27 105 - 138). Both axes involve the juxtaposing of three long-standing images: (1) Spanish injustices to the Indians; (2) the inability of Mexicans to manage their land properly; and (3) Indians being preeminent environmental stewards. In contrast to Kim's formulation of racial triangulation, however, the axes also involve imagery that contradicts these images: the debauched, poverty-stricken Indian; and European culture as a despoiler of the environment. Also in contrast to Kim's formulation, racial triangulation can involve the creation of new identities. In the 1960s Hispano activists began claiming to be heirs to a hybrid culture that included elements of both Native American and Spanish cultures. While this claim to hybridity enabled the creation of new oppositional discourses, the reconciling of contradictory imagery by historicizing the discourses and by other means undermines the new Hispano oppositional discourses as well as Hispano identity itself Racial triangulation is thus a fluid and contested process in which identity formation and the interchange between predominant and oppositional discourses are constitutive of power relations. Contradictory imagery in the discourse facilitates the maintenance of the environmental - racial order, even as it enables subordinates to challenge their racialized positions and to effect change in the distribution of material wealth, rights, and privileges
Trends in world inequality in life span since 1970
The trends in the variance of length of life, and in the variance of length of adult life in particular, are not well understood, while world inequality in length of adult life has remained stagnant. This��research��from the National Bureau of Economic Research (US)��examines life-span inequality in a broad, balanced panel of 180 rich and poor countries observed in 1970 and 2000. While the share of inequality within countries has decreased over time, inequalities between different countries have unambiguously increased.

Trade Bans, Imperfect Competition, and Welfare: BSE and the U.S. Beef Industry
"Between May 2003 and July 2005, the U.S. beef industry faced a total ban on Canadian cattle imports following the discovery of BSE in Canada in May 2003 and restrictions on U.S. beef exports following the discovery of BSE in the United States in December 2003. When the United States reopened its border to Canadian cattle in July 2005, shipments were restricted to cattle less than 30 months of age. The total ban on Canadian cattle imports and restrictions on U.S. beef exports overlapped between January 2004 and July 2005. The restrictions on Canadian cattle imports and U.S. beef exports overlapped for some time after July 2005. This paper addresses theoretically and empirically how to disentangle the impact on the U.S. beef industry of the BSE-related beef trade interruptions in the presence of overlaps and imperfect competition."
