This article extends environmental risk perception research by exploring how potential health risk from exposure to industrial and vehicular air pollutants, as well as other contextual and socio-demographic factors, influence racial/ethnic differences in air pollution health risk perception. Our study site is the Greater Houston metropolitan area, Texas, USA-a racially/ethnically diverse area facing high levels of exposure to pollutants from both industrial and transportation sources. We integrate primary household-level survey data with estimates of excess cancer risk from ambient exposure to industrial and on-road mobile source emissions of air toxics obtained from the U...

Prostate cancer (PCa), a disease, is characterized by abnormal cell growth in the prostate - a gland in the male reproductive system. PCa is one of the leading causes of cancer death among men of all races. Although older age and a family history of the disease have been recognized as the risk factors of PCa, the cause of this cancer remains unclear. Mounting evidence suggests that infections with various viruses are causally linked to PCa pathogenesis. Published studies have provided strong evidence that at least two viruses (RXMV and HPV) contribute to prostate tumourigenicity and impact on the survival of patients with malignant PCa...

The increased mobility of people between and within countries throughout history has contributed to the diversification of populations worldwide. Despite the recent worldwide economic crisis, migration to both Northern and Southern regions in the world and from rural to urban areas has reached all-time highs (United Nations 2013). As a result, local communities have become increasingly diverse with individuals within these communities representing a myriad of races, ethnic groups, countries of origin, languages, religions, socioeconomic strata, histories, and lived experiences...

Limited systematic comparative knowledge exists about patterns of environmental injustices in exposure to varied natural and technological hazards. To address this gap, we examine how hazard characteristics (i.e., punctuated event/suddenness of onset, frequency/magnitude, and divisibility) influence relationships between race/ethnicity, nativity, socioeconomic status (SES), older age, housing tenure, and residential hazard exposure. Sociodemographic data come from a random sample survey of 602 residents of the tricounty Miami Metropolitan Statistical Area (Florida)...

INTRODUCTION: In the US people of color are disproportionately affected by pedestrian crashes. The purpose of this study was to examine the potential for racial bias in driver yielding behaviors at midblock crosswalks in low and high income neighborhoods located in the sprawling metropolitan area of Las Vegas, NV. METHODS: Participants (1 white, 1 black female) crossed at a midblock crosswalk on a multilane road in a low income and a high income neighborhood. Trained observers recorded (1) number of cars that passed in the nearest lane before yielding while the pedestrian waited near the crosswalk at the curb (2) number of cars that passed through the crosswalk with the pedestrian in the same half of the roadway...

This study investigated the performance-related feasibility and physiological benefits of purposefully eliminating propulsive work while descending in mountain biking and compared values to those measured during road descending. Participants cycled uphill on a road at race pace before descending over three conditions (off-road pedalling; off-road coasting; road coasting). Relatively low power output during off-road pedalling was associated with a greater oxygen uptake (p < .01) when compared with off-road coasting despite no difference in vibration exposure (p > ...
