Through the Clean Development Mechanism (CDM) of the Kyoto Protocol, a developed country actor with a binding emission reduction target can use emission reductions from a project implemented in a developing country to meet this target. At the same time, CDM projects are meant to contribute to sustainable development in the host country, as defined by this country. The CDM is often taken to illustrate a broader contemporary turn in environmental policymaking toward market liberalism, flexibility, and pluralism, where the governance of the CDM involves ??agency beyond the state?? at different political levels and across various jurisdictions. While such an image of the CDM certainly identifies important aspects, it also downplays the ways in which states govern the CDM, not at the international level but at the domestic level through the host country prerogative to define its sustainable development priorities. Early on in the scholarly debate on the CDM, fears were raised about a ??race to the bottom?? with regard to sustainable development requirements on CDM projects. Our research on Chile confirms that hypothesis, with the important addition, that the ??race?? is not simply a structural feature of the CDM, but a deliberate strategy. We argue that Chile has actively chosen to put only marginal emphasis on securing the CDM??s contribution to sustainable development, and instead uses the CDM primarily as a tool to attract foreign investments, treating carbon credits as just another export product. 相似文献

Climate change has disastrous impacts in the developing world and confronts countries like India with immense challenges.
The dilemma of addressing these challenges encourages the appearance of new modes of agency. However, the extent to which
new agents are able to address these challenges depends on several factors. The aim of this article is to examine these factors
and how they affect the ways in which climate change-related challenges to development are tackled in the case of the Indian
wind energy sector. By firstly examining the attributes and capabilities of the different actors and secondly applying a stakeholder
network analysis, the article identifies different characteristics that support the effective and efficient deployment of
wind energy in one Indian state and hinder it in another. 相似文献

Derrick Bell’s work challenges the dichotomy that separates legitimate legal reasoning from “mere” fiction through hybrids
that play across science fiction, Platonic dialogue, and autobiography. Despite its merits, I argue that Bell’s position reifies
and strengthens, rather than deconstructs, structures of tyranny; it maintains the problematic rhetorical construction of
United States race relations in terms of the black–white divide, either alienating, or leaving little or no room for other
racial groups constructively to revise power and identity. In contrast, bell hooks’, Mari Matsuda’s and Robert Chang’s work,
though tentatively sketched, construes current race and gender relations in terms of a chiaroscuro of power, rather than a
simple dichotomy.

Representative democracy does not necessarily eliminate political corruption. Existing models explain the survival of rent-taking politicians by ideological divisions in the electorate and/or informational asymmetries. The current paper demonstrate that rent extraction can persist even if voters are fully informed and ideologically homogenous. We show that in such an environment, voters may gain by persistently reelecting a rent-taker that limits his rent extraction. Such an equilibrium occurs when voters and politicians do not discount the future too heavily, and the share of honest candidates is relatively small. 相似文献

Purpose
This research fulfills a void in offender mobility discourse. Metropolitan socioeconomic and spatial structure, defined in crime pattern theory as the urban backcloth, plays a significant role in shaping travel behavior; and yet, current analysis of offender mobility continues to favor individual characteristics to account for travel range.Methods
Using a large sample of juveniles, both delinquent and at-risk youth (N = 2,552), this study compared the predictive utility of individual characteristics against indicators of urban backcloth.Results
Delinquent youth were found to be more sensitive to the environmental conditions exerted by community-level socioeconomic characteristics than their at-risk counterparts. However, two factors—intercity hierarchical structure and motor vehicle access—accounted for travel variability among all youth.Conclusions
Offending behavior must be examined within the context of a dynamic environmental context formed by the metropolitan socioeconomic and spatial structure. Delinquents constitute an identifiable subgroup of youth. 相似文献828.

Methodology is presented for the profiling of fentanyl in seized drugs using ultra high performance liquid chromatography in combination with tandem mass spectrometry (UHPLC-MS/MS). Target analysis was performed for 40 fentanyl processing impurities, several of which are markers for a specific synthetic route (Siegfried or Janssen). For the separation of these solutes, an Acquity BEH C18 1.7 μm particle column (150 mm × 2.1 mm) with a binary 1% formic acid (pH 2.0)/acetonitrile gradient was used. For MS/MS detection, an atmospheric pressure positive electrospray source was employed with selected reaction monitoring (SRM). The coupling of the high separation power of UHPLC with the highly selective and sensitive detection of MS/MS is amenable to the determination of synthetic route and linking of drug seizures. The technology is also applicable to exhibits containing trace levels of fentanyl in the presence of significantly excess amounts of heroin and/or adulterants. 相似文献

Mixed evidence has been found regarding how locating in a cluster or a park affects firms?? performance. This paper investigates how locating in different types of clusters and parks interacted by firm size or in-house R&D capability affects a firm??s innovation. Empirically testing the research hypotheses by the data of 165 Taiwan??s manufacturing firms in the information and communication technology sector and taking policy-driven parks (e.g., science parks and industrial parks) and spontaneously clusters as examples, we find that in emerging economies, firms with inferior in-house R&D capability gain more innovation benefits by locating in a science park or a spontaneous cluster while smaller firms gain more innovation benefits by locating in an industry park or a spontaneous cluster. Moreover, our findings also suggest that locating in a science park, smaller firms benefit more than larger firms in terms of innovation performance whereas larger firms benefit more than smaller firms in terms of market performance. The findings suggest that in emerging economies, compared to larger firms, smaller firms are less influenced by negative spillover effect when locating in clusters or parks. 相似文献
