In The Sound of Exclusion, Christopher Chávez critically examines National Public Radio's professional norms and practices that situate white listeners at the center while relegating Latinx listeners to the periphery. By interrogating industry practices, we might begin to reimagine NPR as a public good that serves the broad and diverse spectrum of the American public.

The second of two volumes filling a gap in the literature in understanding and responding to this grand challenge, this edited collection focuses particularly on the impact and complex consequences of migration, youth experiences and the functioning of digital spaces, and the shaping of youth identity through exposure to both.

Measurements of the noise attenuation provided by five flight helmets were obtained on a manikin head and compared with attenuation measurements obtained on human subjects according to the USASI Standard for Evaluating Real-Ear Attenuation at Threshold. The two sets of measurements were similar. The manikin method has certain advantages which should be considered in terms of the particular requirements of an evaluation program: (1) a helmet can be optimally fitted with little expenditure of time; (2) variability introduced by human factors is kept at a minimum; (3) high levels of noise can be used as the test stimulus; (4) visual and auditory monitoring of the attenuated noise provides the experimenter with a precise appraisal of the fit as adjustments are made; (5) manikin measurements are particularly useful in revealing improvements in attenuation resulting from minor modifications.

In 1991 the U.S. Army sent Major Melissa Wells-Petry to the University Of Virginia Law School to research and write an in-depth report on the legal and social implications of admitting homosexuals into the armed forces. But the report was never released--it contradicted "politically correct" opinion. Now comes the release of the report the Army doesn't want you to read.
