Behavioral Changes for African Americans To Improve Health, Embrace Culture, and Minimize Disparities

In spite of significant advances in the prevention, diagnoses, and treatment of most chronic diseases, there is evidence that racial and ethnic people of color tend to receive lower quality of care and less preventive interventions than the majority members of a community. While our health system should improve its efforts at addressing and reducing disproportionality in health care, African Americans can make behavioral changes through diet and exercise that will reduce their susceptibility to chronic illnesses. This article first reviews the prevalence, disparities, and characteristics of chronic diseases impacting the African American population. Second, it discusses culturally connected practices associated with the management, treatment, and prevention of chronic diseases among African Americans; more specifically, it explores cultural relevance as it pertains to diet and physical exercise. This paper outlines a process of behavioral change that will assist African Americans in transitioning to a healthier life style. Finally, it argues that African Americans can embrace behavioral changes to promote better health while continuing to embrace the richness of their culture

Thermophotovoltaic Spectral Control

Spectral control is a key technology for thermophotovoltaic (TPV) direct energy conversion systems because only a fraction (typically less than 25%) of the incident thermal radiation has energy exceeding the diode bandgap energy, E{sub g}, and can thus be converted to electricity. The goal for TPV spectral control in most applications is twofold: (1) Maximize TPV efficiency by minimizing transfer of low energy, below bandgap photons from the radiator to the TPV diode. (2) Maximize TPV surface power density by maximizing transfer of high energy, above bandgap photons from the radiator to the TPV diode. TPV spectral control options include: front surface filters (e.g. interference filters, plasma filters, interference/plasma tandem filters, and frequency selective surfaces), back surface reflectors, and wavelength selective radiators. System analysis shows that spectral performance dominates diode performance in any practical TPV system, and that low bandgap diodes enable both higher efficiency and power density when spectral control limitations are considered. Lockheed Martin has focused its efforts on front surface tandem filters which have achieved spectral efficiencies of {approx}83% for E{sub g} = 0.52 eV and {approx}76% for E{sub g} = 0.60 eV for a 950 C radiator temperature

From the old guard to the lads movement: Hybrid racism and white supremacism in Australia

This chapter compares contemporary far-right movements in Australia with far-right movements from the 1930s. By examining the provenance and manifestations of the far right in these periods, the chapter notes the importance of Australia’s early history, especially with regard to the “White Australia Policy” that contributed to a rejection of Australia’s Indigenous population as well as non-white immigration. Movements from both eras, apart from their resurgence during times of apparent or feared economic decline, are shown to exhibit similar characteristics in adherence to a nativist populism, hybrid racism, ambivalence to democracy, and congruence with transnational far-right movements. The chapter concludes that as late as 2019 the ruling coalition government in Australia gained from a politically expedient electoral relationship with a xenophobic far right with roots in earlier far-right movements
