On April 20, 2010, the Deepwater Horizon oil rig exploded, and oil spilled from the breached well-head for months, leading to an unprecedented environmental disaster with implications for behavioral health. Disasters are thought to affect behavioral health, and social capital is thought to ameliorate behavioral health impacts after disasters, though empirical evidence is mixed. One possible explanation for the discrepancy in findings relates to the activation of social capital in different contexts. In a disaster context, certain types of social capital may be more beneficial than others, and these relationships could differ between those directly affected by the disaster and those who are unaffected. The goal of this study is to assess the relationships between different forms of social capital (community engagement, trust, and social support) on different behavioral health indicators (depression, anxiety, and alcohol misuse) using data from the first wave of the Survey of Trauma, Resilience, and Opportunity among Neighborhoods in the Gulf (STRONG), a probabilistic household telephone survey fielded 6 years after the onset of the Deepwater Horizon oil spill (DHOS). We employ a structural equation modeling approach where multiple social capital and behavioral health variables can be included and their pathways tested in the same model, comparing the results between those who reported experiencing disruptions related to the DHOS and those who did not. Among those who experienced the DHOS, social support was negatively associated with both depression (β?=???0.085; p?=?0.011) and anxiety (β?=???0.097; p?=?0.003), and among those who did not experience the DHOS, social support was positively associated with alcohol misuse (β?=?0.067; p?=?0.035). When controlling for the other social capital variables, social support was the only form of social capital with a significant relationship to behavioral health, and these relationships differ based on whether or not a person experienced the disaster. This suggests that social capital does not have a uniformly ameliorative relationship with behavioral health in the aftermath of disasters.

Abstract

Given the linkages between natural resources and social conflicts, evidence increasingly shows that successful natural resource management requires conflict mitigation and prevention. However, there may be a gap in practice between knowing what processes and tools need to be used to manage conservation conflicts and how to actually implement them. We present learning from a practice-based case study of conflict management in the Amarakaeri Communal Reserve in the Peruvian Amazon that aimed to develop natural resource governance institutions and build stakeholder capacity, including of indigenous groups, to navigate existing conflict resolution mechanisms. Through applying good practices in conservation conflict management and collaborative governance, we generated important lessons on the practical considerations involved in collaborative conservation. These lessons, while specific to our case, could be applied to a variety of protected areas facing complex social-ecological systems dynamics and wicked problems.  相似文献   

Ecological Worldview as the Central Component of Environmental Concern: Clarifying the Role of the NEP     

Chenyang Xiao  Riley E. Dunlap  Dayong Hong 《社会与自然资源》2019,32(1):53-72

This study examines whether an ecological worldview—operationalized by the New Ecological Paradigm (NEP) Scale--serves as the source of coherence of Environmental Concern (EC). Using data on four samples from the 1992 Gallup “Health of the Planet” Survey and the 2003 and 2010 Chinese General Social Surveys, we found that in all samples not only is the NEP the most powerful predictor of EC, but it also mediates the effects of socio-demographic variables on EC as hypothesized. The results confirm that the NEP is the source of coherence of EC, making it a meaningful construct.  相似文献   

Measuring fishery profitability: An index number approach     

《Marine Policy》2014

Tracking the financial well-being of vessels that depend on a marine fishery resource is an important function of regulators. This research demonstrates how simple indices can be constructed and utilized to track the economic well-being of vessels operating in the Northeast (USA) Multispecies (Groundfish) Fishery. The indices, which use both public and private data, can separately track trends in inputs, outputs, and prices. For the Northeast Multispecies Fishery, the indices reveal that the economic well-being of the groundfish fleet has improved under catch share management through gains in productivity.  相似文献   

Hiding in the howardites: Unequilibrated eucrite clasts as a guide to the formation of Vesta's crust          下载免费PDF全文

204 howardites in the National Meteorite Collection at the Smithsonian were examined for the presence of fine‐grained eucrite clasts, with the goal of better understanding the formation of the uppermost crust of asteroid 4Vesta. Eight clasts were identified and characterized in terms of their textures and mineral chemistry, and their degree of thermal metamorphism was assessed. The paucity of fine‐grained eucrites, both within the unbrecciated eucrites and as clasts within the howardites, suggests that they originate from small‐scale units on the surface of Vesta, most likely derived from partial melting. Six of the eight clasts described were found to be unequilibrated, meaning that they preserve their original crystallization trends. The vast majority of eucrites are at least partially equilibrated, making these samples quite rare and important for deciphering the petrogenesis of the vestan crust. Biomodal grain populations suggest that eucrite melts often began crystallizing pyroxene and plagioclase during their ascent to the surface, where they were subject to more rapid cooling, crystallization, and later metasomatism. Pyroxene compositions from this study and prior work indicate that the products of both primitive and evolved melts were present at the vestan surface after its formation. Two howardite thin sections contained multiple eucrite composition clasts with different crystallization and thermal histories; this mm‐scale diversity reflects the complexity of the current day vestan surface that has been observed by Dawn.  相似文献   

Policy options to streamline the carbon market for agricultural nitrous oxide emissions     

Meredith T. Niles  Hannah Waterhouse  Robert Parkhurst  Eileen L. McLellan  Sara Kroopf 《Climate Policy》2019,19(7):893-907

The majority of emissions of nitrous oxide – a potent greenhouse gas (GHG) – are from agricultural sources, particularly nitrogen fertilizer applications. A growing focus on these emission sources has led to the development in the United States of GHG offset protocols that could enable payment to farmers for reducing fertilizer use or implementing other nitrogen management strategies. Despite the development of several protocols, the current regional scope is narrow, adoption by farmers is low, and policy implementation of protocols has a significant time lag. Here we utilize existing research and policy structures to propose an ‘umbrella’ approach for nitrogen management GHG emissions protocols that has the potential to streamline the policy implementation and acceptance of such protocols. We suggest that the umbrella protocol could set forth standard definitions common across multiple protocol options, and then modules could be further developed as scientific evidence advances. Modules could be developed for specific crops, regions, and practices. We identify a policy process that could facilitate this development in concert with emerging scientific research and conclude by acknowledging potential benefits and limitations of the approach.

Key policy insights

• Agricultural greenhouse gas market options are growing, but are still underutilized

• Streamlining protocol development through an umbrella process could enable quicker development of protocols across new crops, regions, and practices

• Effective protocol development must not compromise best available science and should follow a rigorous pathway to ensure appropriate implementation

Beyond anecdotal evidence: Do subsidized housing developments increase neighborhood crime?     

《Applied geography (Sevenoaks, England)》2015

While planners and policymakers have advocated the need for project-based subsidized housing, they often face the challenge of strong community opposition due to the negative perceptions of subsidized housing and subsidized households, and the fear that these developments and residents would bring increased crime. This paper aims to extend beyond anecdotal evidence by examining the impact of a popular U.S. affordable housing program, the Low-Income Housing Tax Credit (LIHTC) program, on neighborhood crime rates. We estimate the levels and trends in neighborhood crime before and after LIHTC developments, based on crime incidents data from 2000 to 2009 in Austin, Texas, using the Adjusted Interrupted Time Series–Difference in Differences (AITS–DID) approach to clarify the causal direction of impacts of LIHTC developments. Results show that LIHTC subsidized housing tended to be developed in neighborhoods where crime was already prevalent, and contrary to popular perception, LIHTC developments have a mitigating impact on neighborhood crime. These results suggest that LIHTC developments may be an effective tool for revitalizing distressed neighborhoods by ameliorating the “broken windows” problem and reducing neighborhood crime.  相似文献   

Mexico's drug networks: Modeling the smuggling routes towards the United States     

《Applied geography (Sevenoaks, England)》2015

Drug smuggling routes are chosen to maximize profit while minimizing costs. Routes with the least drug transportation costs and the lowest risk for drug confiscation and gang fight are most preferred. This study attempts to predict the ground trafficking corridors for transporting marijuana and opium derivatives from Mexico to the United States border. The cost surface, representing impedance to transport illicit drugs, is modeled by considering physical, socio-demographic, and drug violence factors. The impedance is then transferred to the road network to represent the cost for moving drugs along the roads, which becomes the main input for network analysis. The results from the routes simulation confirm largely the known territory divisions and the drug trafficking routes of the major Mexican drug organizations. The findings help us understand the development of drug trafficking routes in Mexico, which can potentially enhance our capability to predict the dynamics of drug smuggling routes.  相似文献   

Industry-academe linkages in the Philippines: Embedding foreign investors,capturing institutions?     

《Geoforum》2015

The global sourcing of services from developing countries has made human capital a key local asset for attracting foreign direct investment. This paper analyses to what extent individual companies engage in linkages and collaborations with universities and how the education sector responds to the new demands of the knowledge economy. Offshore services are generally recognised as ‘footloose’ investments with limited local linkages. A case study of industry-academe linkages in the growing business process outsourcing sector in the Philippines finds that foreign investors engage in active embedding and develop linkages with human resource providers, leading to increased territorial embeddedness. This paper investigates the kind of linkages created, which actors engage in them and their motivations, to understand the resulting implications for local economic development. Interviews with foreign investors and higher education institutions reveal that most collaboration is initiated by large call centre companies and focuses on entry-level skills development for their operations. I argue that multinational corporations have been able to capture local institutions and introduce changes in the education system to supply mainly lower-end skills. While increasing the available talent pool and raising the competitiveness for further investments, this presents challenges for upgrading into higher value-added services and potentially transforms the country into a dependent market economy.  相似文献   

A new genus of Scoliidae (Insecta: Hymenoptera) from the Lower Cretaceous of northeast China     

《Cretaceous Research》2015

A new genus and species of Scoliidae (Hymenoptera), Sinoproscolia yangshuwanziensis gen. et sp. nov., is described from the Lower Cretaceous Yixian Formation in Inner Mongolia, China and attributed to the subfamily Proscoliinae. Some characteristics, including complete crossveins 1r-rs and 2r-m in the forewing, and a free section present in almost all longitudinal veins indicate a basal position of the new genus in Proscoliinae. The presence of vein 2A suggests its atavistic origin in Sinoproscolia gen. nov. rather than a true plesiomorphy.  相似文献
