Homes in multiple occupancy (HMOs) – residential properties containing common areas shared by several households – are a growing feature of the housing landscape across the UK. They have often been subject to political stigmatization as a result, in part, of comprising poor quality dwellings. This paper uses a “spaces of exception” framework to explore the juridical and material mechanisms involved in the rise of fuel poverty among people living in HMOs. Having analysed evidence from interviews, census data and the secondary literature pertaining to the English context, we highlight the processes that have led to the biopolitical othering of this housing stock in institutional and infrastructural terms. We argue that the expansion and persistence of fuel poverty in HMOs are promoted not only by the disproportionate concentration of low-income residents in relation to the rest of the private rented sector, but also by the socio-technical configurations that underpin this type of housing. Fuel poverty can thus be seen as the joint outcome of broader practices of legal, political and material delegitimization.  相似文献

The purpose of this article is to analyze perceptions and activities of policy actors, who are actively involved in or knowledgeable about the politics of hydraulic fracturing in New York, Colorado, and Texas. The analysis is guided by research questions drawn from the Advocacy Coalition Framework that focus on policy actors’ policy positions, problem perceptions, political capacity, activities, and interactions. In doing so, we examine the differences between those policy actors who are opposed to hydraulic fracturing relative to those who support hydraulic fracturing across the three states using data from online surveys administered in 2013 and 2014. The results show polarization between opponents and proponents in their policy positions on hydraulic fracturing, which are associated with problem perceptions. Proponents and opponents of hydraulic fracturing also have different capacities, activities, and interactions. The results are similar across states but not without nuanced differences, including greater polarization in New York, higher levels of government support for proponents of hydraulic fracturing in Texas, and more frequent coalition building in Colorado.  相似文献

Where electricity access is limited, solar lanterns are a viable and relatively inexpensive source of basic lighting for households. However, the creation of commercially viable business models for solar lanterns is difficult because the customers are poor and make decisions under tight liquidity constraints. To understand the economics of technology adoption in the case of solar lanterns, we conduct a field experiment on willingness to pay (WTP) for solar lanterns in rural Uttar Pradesh. Applying the Becker–DeGroot–Marschak method of eliciting WTP, we evaluate the ability of a trial period and postponed payment to increase sales. We find no evidence for the effectiveness of the trial period and only weak evidence for the positive effect of postponed payment. Overall, WTP for the product among the customers is low. There is no clear evidence for concerns about the uncertain quality of the product, liquidity constraints, or present‐bias. In this context, policies to subsidize very small solar lanterns would not correct a market failure, as people appear to have only a limited interest in the product.  相似文献

This article assesses the regulatory response to fracking by Saskatchewan, Canada's second largest oil‐producing province. Public officials and industry representatives claim fracking regulations are “comprehensive” and “robust”; however, there has been no comparative assessment of this claim. To address this gap, we outline the dominant regulatory pathways of U.S. states and Canadian provinces, ranging from applying existing regulations with minimal revisions, to enacting broader revisions or bans. We account for this variation using a framework from Davis ( 2012 ) emphasizing governments’ dependence on the oil sector, the level of support for fracking among elected officials and policy makers, and the influence of key “constituencies.” The article then traces the growth and impact of fracking in Saskatchewan and analyzes new trends in the province's regulation of fracking. Given the province's application of existing regulations with minimal revisions and active weakening of enforcement, we identify Saskatchewan as taking Rabe and Borick's ( 2013 ) “conventional” regulatory approach, typical of Davis's “energy dominant” states.  相似文献

This research examines the impact of increasing the stringency of renewable portfolio standards (RPS) on the consumption of energy produced from renewable sources. Putting prior findings in the context of policy learning, first we focus on technological innovation, factor endowments, and economic energy dependence of American states to track how RPS have proliferated and strengthened. Next, we look at the net effect of this RPS evolution on state fossil fuel energy divestment. To evaluate the interplay between: a) the political desire to lower fossil fuel use, b) technological feasibility to do so, and c) the economic trade‐offs and risks, we focus on the industrial sector dependence on energy security and affordability. Our results indicate that energy security is a priority and even in light of increasing RPS stringency, states with relatively weak but mandatory RPS are leaders in aggregate renewable energy consumption. This fact is due to favoring biofuel and hydro generation rather than solar and wind because of lower deployment costs.  相似文献

Innovation is the central element of climate change policy in many jurisdictions. Reduced to technology development and linked to market‐driven priorities, innovation accommodates the interests of large emitters in the energy sector and underpins a sustainable development discourse that denies ecological limits to economic growth. This study examines the use of innovation as a key component of climate change policy in the case of Alberta's Climate Change Emissions Management Corporation, utilizing a political economy approach to explain the drivers of government funding priorities. An analysis of this technology fund's investments over nine years, under two different governments, revealed that nearly half of the revenue has been used to subsidize R&D in the fossil fuels industry in the name of clean energy development, and that this priority has continued despite recent government commitments under the Paris CoP agreement. The carbon levy system that generates revenue for the fund has been unsuccessful in incentivizing facility reductions, pointing to the need for more stringent regulation. Innovation as a framework for transition to a post‐carbon economy is severely limited by its exclusion of the roles of social knowledge and citizen participation in envisaging and designing paths for change.  相似文献

Comparisons of polyvinyl chloride electrical tape typically rely upon evaluating class characteristics such as physical dimensions, surface texture, and chemical composition. Given the various techniques that are available for this purpose, a comprehensive study has been undertaken to establish an optimal analytical scheme for electrical tape comparisons. Of equal importance is the development of a quantitative means for sample discrimination. In this study, 67 rolls of black electrical tape representing 34 different nominal brands were analyzed via scanning electron microscopy and energy dispersive spectroscopy. Differences in surface roughness, calendering marks, and filler particle size were readily apparent, including between some rolls of the same nominal brand. The relative amounts of magnesium, aluminum, silicon, sulfur, lead, chlorine, antimony, calcium, titanium, and zinc varied greatly between brands and, in some cases, could be linked to the year of manufacture. For the first time, quantitative differentiation of electrical tapes was achieved through multivariate statistical techniques, with 36 classes identified within the sample population. A single-blind study was also completed where questioned tape samples were correctly associated with known exemplars. Finally, two case studies are presented where tape recovered from an improvised explosive device is compared with tape recovered from a suspect.  相似文献

To explain cognitive capture, economic sociologists often examine the structure of relationships between regulators and market participants. This paper argues that the nature of regulators' misperception should be subject to analysis as well. Different types of misperceptions develop over timelines of varying lengths. Depending on the misperception, different sets of relationships and parties may therefore be the cause of regulators' capture. The paper illustrates this point with a case study of regulators' failure to detect pervasive market power in California's electricity markets between 1998 and 2001. Existing explanations focus on sellers' short-term attempts to distract regulators from widespread evidence of market power. Using data from three archives and in-depth interviews, I show that the regulators did not fall prey to such “information problems.” Instead, their misperception resulted from a more foundational “worldview problem.” This error affects regulators' basic conception of the marketplace and can be traced to earlier and more gradual forms of influence exerted by utilities that, ironically, would become the victims of market power.  相似文献
