Even as the 2016 elections brought increased public attention to rural life, stereotypes and misconceptions abound. One of these misperceptions is the generalization that prices are lower in rural areas. This article is a restudy of Zimmerman, Ham, and Frank (2008) research on geographic differences in the costs of living. Asking the same fundamental question—if someone bought the same thing in a rural and urban area, would they pay the same price?—and using the same methodology, the results 10 years later indicate that, contrary to popular perception, there was again no consistent pattern of lower prices in rural counties and no consistent pattern of a lower rural cost of living in all of the rural areas. While prices are only one piece of the larger picture of how rural households meet their needs, in addition to price differences, the results highlight how differences in rural life create additional costs that extend beyond prices.  相似文献

Although researchers have broadly addressed how race, party identification, political ideology, and binary gender categories influence climate change opinions, little attention has been paid to the relationship between sexuality and gender variance (LGBTQ+ identity broadly) and climate change perceptions. Using a quota-based survey from 2022 that approximates the US population on key demographic characteristics and oversamples LGBTQ+ individuals, we assess the degree to which LGBTQ+ individuals' climate change beliefs and risk perceptions are comparable to cisgender, heterosexual (cishet) individuals, specifically examining climate change beliefs, the perceived threat climate change poses, and worry about climate change. We argue that LGBTQ+ individuals' views are likely to be distinct from their cisgender heterosexual (cishet) counterparts for three reasons: climate change is likely to exacerbate existing structural inequalities, create disaster responses that reinforce heteronormative and discriminatory patterns, and activate LGBTQ+ political culture. We find evidence that LGBTQ+ individuals express higher agreement with climate change beliefs, identify climate change as a greater threat, and worry more about climate change when compared to their cishet counterparts.  相似文献

Per- and poly-fluoroalkyl substances (PFAS) are ubiquitous in the environment and are detected in wildlife and humans. With respect to human exposure, studies have shown that ingestion is the primary route of exposure; however, in certain settings, exposure via inhalation could also be a significant source of exposure. While many studies examined toxicity of PFAS via ingestion, limited information is available for PFAS toxicity via the inhalation route, translating into a lack of exposure guidelines. Consequently, this article examined whether route-to-route extrapolation to derive guidelines for inhalation exposure is appropriate for PFAS. Perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) were used as exemplary PFAS given the abundance of toxicity data for these two compounds. Our evaluation determined that available toxicity and toxicokinetic data support route-to-route extrapolation for PFAS in order to derive inhalation-based standards. Results from this analysis suggest that an air concentration of 7.0 × 10−5 mg/m3 (or 0.07 μg/m3) would be an appropriate RfC for PFOA and PFOS assuming the 2016 EPA RfD of 0.00002 mg/kg-day, whereas use of the interim RfDs proposed in 2022 of 1.5 × 10−9 and 7.9 × 10−9 mg/kg would yield much lower RfCs of 5.25 × 10−9 and 2.77 × 10−8 mg/m3 (or 5.25 × 10−6 and 2.77 × 10−5 μg/m3) for PFOA and PFOS, respectively.  相似文献
