It is suggested that natural resource companies undertaking large-scale projects may be expanding the scope of corporate social responsibility by working to enhance the capabilities of the public sector. Naturally companies are concerned to protect their investments, and to ensure their viability. They will therefore invest in necessary infrastructure and facilities of all types, where those are lacking. Such investment often provides benefits to the wider community, but with a few exceptions these are normally incidental byproducts rather than inherent objectives. The motivation for companies to provide resources of all types in order to enhance the capabilities of the public sector to provide public services is usually an expectation is that the tangible benefits will exceed the costs, rather than altruism. One driving force is to secure and maintain a company's social licence to operate. More recently competition from Chinese firms is prompting private sector companies to offer comparable investments in infrastructure. It is unclear whether investment in public sector capabilities is cyclical and liable to cutbacks when market conditions deteriorate. Changing market conditions affect not just corporate willingness to spend but also host countries’ bargaining strengths. In boom periods host countries will be more able to secure straightforward financial benefits through higher tax receipts than when markets are weak. Beyond the specific needs of individual projects corporate policies are strongly influenced by the beliefs of senior managers. External pressures both from international institutions and from NGOs also drive corporate behaviour. The success of investment in public sector capabilities relies in the end on the responses of host countries, and on how closely the objectives and interests of the government are aligned with maximising the nation's long term wealth and welfare. Where they are not corporate resources may be frittered away. There are also questions over the legitimacy of corporate investments, especially by foreign-owned companies. They have a right to offer advice and protect their legitimate interests, but these may not always coincide with those of their host countries. There is a range of questions about the appropriate role of companies, which lead on to feasible and effective ways of improving weak governance.  相似文献

The article begins by describing the difficult living conditions of many people in the hill slopes (laderas) of La Paz, Bolivia, demonstrating that they are exposed to a combination of natural and social hazards. 1 It shows that residents, community leaders and city planners tend to underestimate or deny risk, with important consequences for risk management, such as a failure to raise risk awareness. The article then proposes some hypotheses to explain risk perceptions in La Paz, discarding the usual single-approach interpretations and suggesting instead more nuanced theoretical explanations to account for why people build their homes in such hazardous environments.  相似文献

Many cities in developing nations have experienced an influx of poor migrants in search of work. This population influx has often been accommodated through land squatting, irregular construction and unauthorised housing. For the urban poor, this has resulted in immediate affordable housing; however, this housing frequently has long-term vulnerability to natural hazards. This article examines the ways in which squatters in Istanbul, Turkey, understand the seismic vulnerability of their unauthorised housing. Distrust of professional engineers and contractors has led Istanbul squatters to believe that self-built housing will not only be less costly but also safer than commercially built housing. The impact of residents' risk perceptions on their vulnerability to natural hazards is examined through a comparison of social attitudes regarding safe housing and the quality of unauthorised construction. This comparison highlights how squatters' risk perceptions necessitate innovative means of reducing vulnerability in unauthorised neighbourhoods of developing cities.  相似文献

城市气象灾害防御措施的改进是防灾减灾的有效手段,但如何在辨识公众支付意愿的基础上,构建多方成本分担的灾害防御制度是解决问题的关键。从成本分担的视角出发,以南京暴雨灾害防御为例,分析公众对增强型城市气象灾害防御的支付意愿及认知资源在其中的重要作用。通过构建由Probit模型和有序Probit模型组成的递归混合模型,探讨认知资源和经济资源在公众支付决策中的重要性。研究表明:认知资源的作用十分明显,且随着公众对暴雨灾害风险感知、防御措施了解程度、防御制度认可程度的提高,公众支付意愿越强。而暴雨灾害风险感知又受到灾害趋势认知和经历的共同影响,这两个变量分别影响风险感知的广度和深度,但受教育程度对风险感知深度的影响并不显著。核心建议是从满足公众对城市暴雨灾害风险、防御措施、灾害趋势等知识的需求,政府应该加强暴雨灾害科普宣传的主动性、提升主管和协同部门的公信力;规范科普知识内容、拓宽科普渠道。  相似文献

In this study, we extract factors by using factor analysis and then adopt them in a regression analysis to investigate the public perception and acceptance of hydrogen energy in Taiwan. Six reliable factors were extracted from the exploratory factor analysis of 29 5-point Likert-type items. Our regression results show that the public perception of hydrogen energy as a green energy, public belief in domestic hydrogen industries being able to conform to international safety standards, and public perception of the cost advantage of hydrogen gas over petroleum have significantly positive effects on support for the development of hydrogen energy in Taiwan. While people have a high level of concern about the safety of hydrogen and its associated technologies, the unsafe perceptions of hydrogen and its associated technologies have no significant effects on their support. In particular, public belief in domestic hydrogen industries being able to conform to international safety standards is a powerful factor that enhances support for hydrogen energy development.  相似文献

Public deliberation is increasingly marshalled as a viable avenue for climate governance. Although climate change can be framed in multiple ways, it is widely assumed that the only relevant public meaning of climate change is that given by the natural sciences. Framing climate change as an inherently science-based public issue not only shields institutional power from scrutiny, but it can also foster an instrumental approach to public deliberation that can constrain imaginative engagement with present and future socio-environmental change. By fostering the normative value of pluralism as well as the substantive value of epistemic diversity, the interpretive social sciences and humanities can assist in opening up public deliberation on climate change such that alternative questions, neglected issues, marginalized perspectives and different possibilities can gain traction for policy purposes. Stakeholders of public deliberation are encouraged to reflect on the orchestration of the processes by which climate change is defined, solutions identified and political collectives convened.  相似文献

农村土地确权登记是国家赋权的重要举措,农户对国家赋权的主观认知则建构了政策实施的重要基础。为辨析不同治理层面国家赋权对农户产权认知的影响特征及其差异性,本文通过理论分析和实证考察相结合的方式,采用引入"国家赋权×农户行为能力"交叉项的Probit模型和Oprobit模型,并利用苏、赣、辽三省2 477户农户的调查数据经验分析了农村土地确权登记在公共治理和村庄自治层面对不同行为能力的农户产权认知的影响。在此基础上,通过求解不同主体行为能力下国家赋权对农户土地产权认知的偏效应,识别了治理层次与主体行为能力的互动特征。研究结果表明,国家赋权更易提高农户对公共治理领域的土地产权安全感知,且对行为能力较强的农户产权安全感知的激励作用大于行为能力较弱的农户,具有典型的主体"歧视性"。经验结果表明,国家赋权更易提高农户对公共治理领域的土地产权安全感知;其次,国家赋权在村庄自治层面对直接行为能力较弱农户的产权安全感知的抑制作用大于直接行为能力较强的农户,但在公共治理层面则对直接行为能力和间接行为能力较强农户的产权安全感知均具有更强的正向激励。为此,本文认为政策改革需关注公共治理和村庄自治层面国家赋权的实施差异及避免主体歧视,产权认知领域的研究则需综合考虑国家赋权、社会规范和主体行为能力三个层次的内在关联。  相似文献

A number of scavenger species have suffered population declines across Europe. In attempts to reverse their decline, some land and wildlife managers have adopted the practice of leaving or placing out carcasses of wild or domestic herbivores to provide a source of carrion. However, this can be a controversial practice, with as yet unclear outcomes for many target species and the ecosystems they are part of. Here we bring out the key aspects of this increasingly common conservation practice illustrated using three contrasting cases studies. We show that the provision of carcasses is often motivated by a desire to benefit charismatic species or to facilitate nutrient cycling throughout an ecosystem. Evidence for the effectiveness of this practice in achieving these objectives, however, is mostly lacking, with ecologists studying “easier” species groups such as beetles and therefore not providing relevant insights. Moreover, conflicts between environmental policies that carcass provisioning is aimed at and other social and economic objectives do occur but these projects are often designed without taking into account this broader context. We conclude that expecting carcasses to simply be “good for biodiversity” may be too naïve a view. A greater knowledge of the impact of carcass provisioning and placement on ecosystems and society at large is required before it can become a more effective conservation tool at a wider scale.  相似文献

Volatile organic compounds at swine facilities: A critical review   总被引:3,自引:0,他引:3

Volatile organic compounds (VOCs) are regulated aerial pollutants that have environmental and health concerns. Swine operations produce and emit a complex mixture of VOCs with a wide range of molecular weights and a variety of physicochemical properties. Significant progress has been made in this area since the first experiment on VOCs at a swine facility in the early 1960s. A total of 47 research institutions in 15 North American, European, and Asian countries contributed to an increasing number of scientific publications. Nearly half of the research papers were published by U.S. institutions.Investigated major VOC sources included air inside swine barns, in headspaces of manure storages and composts, in open atmosphere above swine wastewater, and surrounding swine farms. They also included liquid swine manure and wastewater, and dusts inside and outside swine barns. Most of the sample analyses have been focusing on identification of VOC compounds and their relationship with odors. More than 500 VOCs have been identified. About 60% and 10% of the studies contributed to the quantification of VOC concentrations and emissions, respectively. The largest numbers of VOC compounds with reported concentrations in a single experimental study were 82 in air, 36 in manure, and 34 in dust samples.The relatively abundant VOC compounds that were quantified in at least two independent studies included acetic acid, butanoic acid (butyric acid), dimethyl disulfide, dimethyl sulfide, iso-valeric, p-cresol, propionic acid, skatole, trimethyl amine, and valeric acid in air. They included acetic acid, p-cresol, iso-butyric acid, butyric acid, indole, phenol, propionic acid, iso-valeric acid, and skatole in manure. In dust samples, they were acetic acid, propionic acid, butyric acid, valeric acid, p-cresol, hexanal, and decanal. Swine facility VOCs were preferentially bound to smaller-size dusts.Identification and quantification of VOCs were restricted by using instruments based on gas Chromatography (GC) and liquid chromatography (LC) with different detectors most of which require time-consuming procedures to obtain results. Various methodologies and technologies in sampling, sample preparation, and sample analysis have been used. Only four publications reported using GC based analyzers and PTR-MS (proton-transfer-reaction mass spectrometry) that allowed continuous VOC measurement. Because of this, the majority of experimental studies were only performed on limited numbers of air, manure, or dust samples. Many aerial VOCs had concentrations that were too low to be identified by the GC peaks.Although VOCs emitted from swine facilities have environmental concerns, only a few studies investigated VOC emission rates, which ranged from 3.0 to 176.5 mg d−1 kg−1 pig at swine finishing barns and from 2.3 to 45.2 g d−1 m−2 at manure storages. Similar to the other pollutants, spatial and temporal variations of aerial VOC concentrations and emissions existed and were significantly affected by manure management systems, barn structural designs, and ventilation rates.Scientific research in this area has been mainly driven by odor nuisance, instead of environment or health concerns. Compared with other aerial pollutants in animal agriculture, the current scientific knowledge about VOCs at swine facilities is still very limited and far from sufficient to develop reliable emission factors.  相似文献

As conservation scholars increasingly recognize the critical role of human thought and behavior in determining the persistence of biodiversity across the globe, a growing line of inquiry regarding the validity and comparability of previous applications of core psychological concepts has emerged. Specifically, inconsistent measurement and use of terms, such as attitudes and acceptance, reveal important questions about previous approaches. Given that these concepts differ by definition, yet have been used interchangeably, we explored what drives differences in people's responses when each concept is operationalized in the context of a contested wildlife species, the gray wolf (Canis lupus). To do so, we used data from a 2014 survey of U.S. residents (n = 1287) to test how measures of six concepts (i.e., acceptance, attitudes, benefits, risks, [prior] behavior, and behavioral intentions) often employed in the conservation social sciences were related with a broad set of possible explanatory variables. Despite moderate to strong correlations between all concepts measured (| Pearson's r | = 0.39–0.65, p < 0.001), results revealed considerable variation in their respective relationships with identical explanatory variables. Specifically, although wildlife value orientation (i.e., domination or mutualism) operated fairly consistently across cognitive and behavioral concepts, the relationship between the six concepts and other factors, such as social trust, identification with various interest groups (i.e., hunter, farmer, or rancher, environmentalist, and animal rights advocate), and political ideology (i.e., liberal vs. conservative), varied considerably. Our findings underscore that differences exist in these measures, which could have serious implications for conservationists integrating social science findings in their decision-making processes if they are unaware of the theoretical underpinnings of and distinctions between core psychological concepts.  相似文献
