Several theories compete to explain observed race‐ and ethnicity‐based environmental injustice in society. This paper focuses on analyzing the extent to which firms' siting decisions based on community privilege can explain this outcome. A unique feature of this analysis is that we include analysis of both unwanted land uses (disamenity firms) and desired land uses (amenity firms). The environmental justice analysis of amenities other than green spaces is rare, but amenities are crucial components of urban areas to which environmental justice studies must attend. We use an agent‐based model to explore community outcomes when environmental disamenities choose locations based on low community privilege, and compare this with scenarios in which disamenities only seek to minimize the cost of land. We also assess differences in environmental justice outcomes when amenities choose locations in areas with high community privilege. While disamenities' focus on locating in areas with low community privilege indeed affects environmental equity, the effect of amenity location is also important, and there are powerful interaction effects. The importance of privilege‐based location is found in these simulations regardless of which social group—majority or minority—is assumed to be the privileged group. This study suggests a limitation of EJ policies and models that focus on the politics of disamenity siting without considering the politics of amenity siting.  相似文献

Although the gender gap has dramatically narrowed in recent decades, women remain underrepresented in many science, technology, engineering, and mathematics (STEM) fields. This study examined social and personal factors in relation to adolescent girls’ motivation in STEM (math/science) versus non-STEM (English) subjects. An ethnically diverse sample of 579 girls ages 13–18 years (M = 15) in the U.S. completed questionnaires measuring their academic achievement, ability beliefs, values, and experiences. Social and personal factors were hypothesized to predict motivation (expectancy-value) differently in math/science (M/S) and English. Social factors included perceived M/S and English support from parents and peers. Personal factors included facets of gender identity (felt conformity pressure, gender typicality, gender-role contentedness), gender-related attitudes, and exposure to feminism. In addition, grades, age, parents’ education, and ethnicity were controlled. Girls’ M/S motivation was positively associated with mother M/S support, peer M/S support, gender-egalitarian beliefs, and exposure to feminism; it was negatively related to peer English support. Girls’ English motivation was positively associated with peer English support as well as felt pressure from parents; it was negatively related to peer M/S support and felt peer pressure. The findings suggest that social and personal factors may influence girls’ motivation in domain-specific ways.  相似文献

  • The democratization of the Internet and the growing popularity of amateur video production have given rise to historic levels of voter engagement. In recent times, the populace has turned to YouTube and other similar websites to publicly voice their opinions through the posting of, and response to, amateur political videos. Political communication and campaign managers frequently struggle to consolidate, analyse, and respond to the vast array of commentary posted on the Internet in reply to these videos. The ability to quickly consolidate and interpret viewer responses to political videos provides campaign and communications' managers the opportunity to quickly make policy, positioning, or image changes. This is especially valuable considering that viewer responses provide a potentially unbiased picture of actual voter sentiment. Using the visualization software, Leximancer, we show how conversations around online political spoof videos can be mapped, interpreted, and used as a basis for strategic brand decision‐making. We discuss the implications of our findings, outline the technique's limitations, and trace avenues for further research.

Does civics instruction have an impact on the political engagement of adolescents? If so, how? Analysis of data from CIVED, a major study of civic education conducted in 1999, finds that an open classroom climate has a positive impact on adolescents’ civic knowledge and appreciation of political conflict, even upon controlling for numerous individual, classroom, school, and district characteristics. Furthermore, an open classroom environment fosters young people’s intention to be an informed voter. Results further show that exposure to an open classroom climate at school can partially compensate for the disadvantages of young people with low socioeconomic status.  相似文献

Despite research documenting high rates of violence during pregnancy, few studies have examined the impact of physical abuse, psychological abuse, and posttraumatic stress disorder (PTSD) on miscarriage. Secondary analysis of data collected by the Chicago Women's Health Risk Study permitted an exploration of the relationships among physical abuse, psychological abuse, PTSD, and miscarriage among 118 primarily ethnic minority women. The interaction between maximum severity of abuse and age provided the best multivariate predictor of miscarriage rate, accounting for 26.9% of the variance between live birth and miscarriage outcome. Mean scores of psychological abuse, physical violence, forced sex, and PTSD were significantly higher in the miscarriage group than in the live birth group. Women who experience physical violence and psychological abuse during pregnancy may be at greater risk for miscarriage. Prospective studies can confirm findings and determine underlying mechanisms. Routine screening for traumatic stress and PTSD may reduce rates of miscarriage.  相似文献

Physician-management relationships at HCA: a case study   总被引:1,自引:0,他引:1  
The questions of whether Hospital Corporation of America (HCA), a for-profit hospital company, fostered an environment detrimental to the physician-patient relationship during the period of implementation of the Medicare Prospective Payment System (PPS) was explored. The transition to PPS provided an opportunity to evaluate whether hospital ownership differences affected responses to a payment system which encouraged institutional intervention in the practice of medicine. A case study approach was used to observe the influence of the then largest for-profit hospital corporation upon physicians' medical practice in four owned hospitals. Findings indicated that HCA hospital managers were most directly influenced by the local competitive environment and their own personal agendas in responding to PPS incentives. Corporate influence actually softened payment system incentives to intervene in medical practice by providing a generous supply of capital, and by fostering a corporate culture conducive to cooperative relationships with physicians. Better public understanding of the determinants of hospital behavior is needed to preserve or enhance important social goals such as the physician-patient relationship; easily measurable characteristics such as ownership or bed size explain little about hospital behavior or motivation.  相似文献

This study investigates the consequences of ambiguity in the issue positions of presidential candidates from 1968 to 1980. Two potential consequences are examined: a direct impact and a conditional impact on the vote. The findings indicate no significant direct effect on the vote. However, significant conditional effects were found. Compared to losing candidates, winning candidates were somewhat less likely to hold clear positions when issues were salient to the public and were somewhat more likely to hold ambiguous positions when public opinion was dispersed. They were especially more likely to be ambiguous when their positions substantially differed from the median public position on the issue.  相似文献
