The U.S. electric power sector has experienced a substantial shift of the generation mix since the turn of the century, moving from heavy reliance on coal‐powered generation to one drawing more from natural gas and, more recently, renewables. This transition has been forged by a mix of macroeconomic factors (recession and recovery); technological breakthroughs (horizontal drilling coupled with hydraulic fracturing; improvements in natural gas plant efficiency); clean energy policies at federal, state, and local levels of government; and private sector demands for carbon‐free energy sources. These factors have combined to reduce carbon emissions from electric power generation substantially this century. In this article we examine the extent of this transition, its causes, as well as the distinct American institutional factors steering it, including energy and environmental federalism, electoral politics, and the political economy of clean energy policy enactment and resistance.  相似文献

The establishment of Corruption Eradication Commission (KPK) is as a crucial instrument for fighting systemic corruption and improving public integrity. However, corrupt forces in post‐Soeharto Indonesia found opportunities to develop powerful coalitions built on the legacy of pre‐reform power relationships. This article examines the extent to which the KPK’s initiatives have been impeded by these vested interests. By examining two major cases involving conflicts against senior law enforcement officers – we identify some of the conditions where vested interests have exerted a significant influence in resisting anti‐corruption efforts. Their greatest impact occurred when their attempts to exploit KPK’s institutional weaknesses occurred in a permissive environment where political stakeholders were indecisive or unassertive. The fragmentation within civil society and independent media also seriously undermined on the capacity of anti‐graft supporters to hold corrupt official to account in Indonesia.  相似文献

If a party to an employment contract commits a repudiatory dismissal or resignation, it has long been unclear whether the other party has the option either to terminate or affirm the contract (the elective theory) or whether the former's breach operates to bring the contract of employment to an end (the automatic theory). The recent decision of the Supreme Court in Société Générale (London Branch) v Geys has finally resolved this question. By a majority, the Supreme Court held that the elective theory also applies in the context of a wrongful repudiation of the employment contract by express dismissal or resignation. This note examines the significance of Geys in the context of the common law of the contract of employment and evaluates whether a number of related issues surrounding the breach and termination of the employment contract have been resolved.  相似文献

Abstract: The University of Mississippi has a contract with the National Institute on Drug Abuse (NIDA) to carry out a variety of research activities dealing with cannabis, including the Potency Monitoring (PM) program, which provides analytical potency data on cannabis preparations confiscated in the United States. This report provides data on 46,211 samples seized and analyzed by gas chromatography‐flame ionization detection (GC‐FID) during 1993–2008. The data showed an upward trend in the mean Δ9‐tetrahydrocannabinol (Δ9‐THC) content of all confiscated cannabis preparations, which increased from 3.4% in 1993 to 8.8% in 2008. Hashish potencies did not increase consistently during this period; however, the mean yearly potency varied from 2.5–9.2% (1993–2003) to 12.0–29.3% (2004–2008). Hash oil potencies also varied considerably during this period (16.8 ± 16.3%). The increase in cannabis preparation potency is mainly due to the increase in the potency of nondomestic versus domestic samples.  相似文献
