This article examines Right-wing political performances in the Bolivian Eastern lowlands where regional elites claim to be living under the authoritarian dictatorship of Left-leaning President Evo Morales. We analyse how regional elites advocate for political autonomy through embodied and spectacular performances linked to discourses of indigeneity, human rights and democracy. Right-wing leaders try to legitimise their claims for justice and territorial control by strategically aligning themselves with lowland ‘Indians’ – who are equally wounded by Morales’s plan to run a massive highway though their communities and territories. Through theatrical exhibits in the plaza and a spectacular assembly spotlighting an indigenous representative as an emblematic hero of TIPNIS, regional elites perform a shared history of marginalisation, while simultaneously presenting themselves as ‘saviors’. We argue, however, that there is a dark side to these performances, as they elide long histories of racialised labour and economic injustice in the region.  相似文献

This study aimed to examine changes in depression and anxiety symptoms from before to during the first 6 months of the COVID-19 pandemic in a sample of 1,339 adolescents (9–18 years old, 59% female) from three countries. We also examined if age, race/ethnicity, disease burden, or strictness of government restrictions moderated change in symptoms. Data from 12 longitudinal studies (10 U.S., 1 Netherlands, 1 Peru) were combined. Linear mixed effect models showed that depression, but not anxiety, symptoms increased significantly (median increase = 28%). The most negative mental health impacts were reported by multiracial adolescents and those under ‘lockdown’ restrictions. Policy makers need to consider these impacts by investing in ways to support adolescents’ mental health during the pandemic.  相似文献

This pilot study examined effects of HIV prevention messages about self and partner benefits of antiretroviral therapy (ART) and condom effectiveness on increased intentions for behavior change. Data were from Messages4Men, a study examining prevention messages among 320 HIV-positive and 605 HIV-negative Black and Latino MSM. Men completed a computer-based assessment after message exposure, and multivariable models controlled for risky sex and demographics. A majority of HIV-positive men reported increased intentions for ART use; 22% reported partner benefit information was new. HIV-positive men with a detectable viral load had significantly greater adjusted odds of reporting intentions for ART use. Over half of HIV-negative MSM reported ART benefit information was new, and 88% reported increased intentions to discuss ART use with infected partners. Black MSM anticipated they would increase condom use in response to the self and partner benefit messages. Tailored messages on benefits of ART are needed for MSM.  相似文献

This paper studies how the school choice policies that subsidize private school attendance using public funds affect the spatial distribution of private schools in the United States. Private school choice programs enacted between 1997 and 2010 are examined and linked to private school provision 2 years later. The paper finds that school choice policies lead to more private schools where the input to public schools is lower and the pool of students with special needs is larger. Yet the introduction of means‐tested school choice programs does not necessarily lead private schools to locate in low‐income neighborhoods. (JEL I2, H4, R3)  相似文献

Worldwide, cities are investing in greenspace to enhance urban quality of life and conserve biodiversity. Cities should ensure these investments do not unintentionally result in ecosystem disservices. Municipal management decisions regarding urban greenspaces, such as mowing frequency, could influence mosquito communities and public health. We examined how mowing, resultant vegetation characteristics, and landscape context influenced adult mosquito abundance in urban vacant lots. We sampled adult Culex and Aedes mosquitoes in a network of vacant lots within eight Cleveland, Ohio, USA neighborhoods in 2015 and 2016 using CO2-baited light traps and grass-infused gravid traps. For each lot, we quantified vegetation characteristics, including plant diversity, bloom area, and biomass, as well as the surrounding landscape composition at radii of 60 and 1000 m. We found that periodic mowing did not significantly affect mosquito abundances. However, vacant lots with more diverse plant communities were associated with a greater light trap capture of both Culex and Aedes. Both mosquito genera declined in light trap catches with increased impervious surface at 60 m. Similarly, Culex (gravid trap) declined with the amount of built infrastructure at 1000 m. In contrast, Aedes (light trap) increased with the concentration of buildings in the landscape at 1000 m. Our findings indicate that reducing the frequency of mowing within vacant lots will not necessarily increase adult mosquito abundance. Nonetheless, mosquito surveillance and management should be considered when planning conservation-focused greenspaces, as vegetation design choices and the landscape context of a site do influence vector abundance and potentially disease risk.

Parental conflict is associated with negative effects on children, and child feelings of involvement in conflict might exacerbate negative outcomes. Research has yet to explore the long-term impact of both parental conflict and caught feelings. In a sample of college students, linear regressions (N = 800) indicated that regardless of parent marital status, children’s feelings of involvement in parental conflict were important predictors of academic and psychological functioning, and in some cases mediated the relationship between conflict and adult child outcomes. Given that parental conflict is common, it appears important to minimize children’s involvement in conflict, as it can have lasting impacts.  相似文献

In the United States, residential yards are typically overlooked for biodiversity conservation, yet they account for a significant portion of urban green space. Yard vegetation can serve as valuable habitat patches for insect pollinator populations in cities, providing important foraging and nesting resources. Based on long-term native bee sampling data, we investigate the social and cultural drivers shaping front yard vegetation composition and configuration at two study sites with consistently low native bee species diversity and abundance. We employ quantitative remote sensing approaches with analysis of qualitative interview data to examine residential vegetation patterns and analyze the socio-cultural relationships between people and vegetation. Data analyses reveal both study sites have lower levels of vegetation composition and complexity, resulting in reduced habitat resources. We find neighborhood public-facing landscaping is shaped by various socio-cultural influences: aesthetics, norms, reference-group behavior, institutions, socioeconomics, and identity. Front yard land-use and decision-making practices are particularly meaning laden, as these spaces are often perceived as visible representations of longstanding neighborhood identity and contiguous common areas to be managed to a “perfect lawn” ideal. The quantitative and qualitative data are used to characterize the two study sites and inform future urban conservation and development efforts salient to citizen stakeholders.  相似文献

The provisions of UK law offer no specific protection to gay men and lesbians suffering discrimination in the workplace on the grounds of sexual orientation. Such discrimination may take many forms and can result in ‘fair’ dismissal in certain circumstances. This article considers the degree of legal protection available under current provisions and investigates possible sources for the development of specific anti‐discrimination legislation. It is concluded that, despite the application of certain aspects of employment law, the level of protection afforded to this group of workers amounts to an equality deficit in comparison to the legal redress available to those discriminated against on other grounds. Although the development of human rights legislation may have some application in this context, the combination of institutionalized discrimination and wider public policy concerns suggest that the introduction of specific legislation aimed at eliminating such discrimination in the United Kingdom is still some way off.  相似文献

Asuccessful revenue management system requires accurate demand forecasts for each customer segment. The forecasts are used to set booking limits for lower value customers to ensure an adequate supply for higher value customers. The very use of booking limits, however, constrains the historical demand data needed for an accurate forecast. Ignoring this interaction leads to substantial penalties in a firm's potential revenues. We review existing unconstraining methods and propose a new method that includes some attractive properties not found in the existing methods. We evaluate several of the common unconstraining methods against our proposed method by testing them on intentionally constrained simulated data. Results indicate our proposed method outperforms other methods in two of three data sets. We also test the revenue impact of our proposed method, expectation maximization (EM), and “no unconstraining” on actual booking data from a hotel/casino. We show that performance varies with the initial starting protection limits and a lack of unconstraining leads to significant revenue losses.  相似文献
