A 21st Century Low‐Carbon Transition in U.S. Electric Power: Extent,Contributing Factors,and Implications

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.

Congressional Attention and Opportunity Structures: The Select Energy Independence and Global Warming Committee

This article examines the role that overlapping committee jurisdictions play in fostering or hindering attention to environmental and energy issues in the U.S. Congress. The Select Energy Independence and Global Warming Committee, created by House Democrats in 2007 , and its chairman Rep. Ed Markey took advantage of opportunities within the existing jurisdictional arrangement to increase attention to these issues despite lacking any legislative authority. Data from the 110th and 111th Congresses show that the Select Committee held more hearings on climate change and alternative energy, and on environmental and energy policy generally, than any other committee. The committee also increased the range of sources informing debate on these issues by calling different witnesses than other committees. These findings have important implications for the relationship between institutional structure and agendas and for Congress' policy‐making role on energy and the environment.     

Projecting the Arena of Inclusion: The Case of South Korea in Pursuing a Phased Inclusive Growth Process

South Korea created a mechanism that fuels inclusive growth, a process that coevolves economic growth and social well‐being. This study attempts to elaborate on the context and preconditions for development that would manifest salience policy implications for moving up the industrial value chain and attain inclusive growth. We contend against the view of simplified growth cum equity that is used to elucidate the success of Korea's socioeconomic development (economic miracles). Our findings informed us that there were intense measures taken throughout different phases of Korea's industrial development. In addition, we observed in many occasions intense negotiations between the state, firms, and civil society for social welfare and a better working environment. This led to a pursuit for inclusive growth in the post catching‐up phase that blended together many inclusive agendas, realizing growth that coevolved industrial upgrading and social welfare. This article seeks to explain how Korea populated its arena of inclusion in the process of pursuing rapid industrialization. The overview of different phases of development provides normative principles that are useful as a guide for other economies which aspire to attain similar development.     

Identifying the Causes of Issue Attention and Policy Change: Evidence from U.S. Offshore Oil and Natural Gas Drilling Policy, 2008

The flow of attention in the policy process is dynamic and disruptive. While we know changes in issue attention often result in policy change, the causal mechanisms underlying the different stages of the attention allocation process remain unclear. This article uses Punctuated Equilibrium Theory to examine an underdeveloped aspect of issue attention within policy‐making institutions: how specific policy indicators influence the entry and exit of issues on policy‐making agendas. Partisan issue attention in the House of Representatives is used to analyze a significant change to U.S. offshore oil and natural gas drilling policy in 2008. The results highlight how historically high gasoline prices precipitated a shift in attention to offshore drilling and subsequent policy change. Moreover, gasoline prices Granger‐cause attention to energy policy in partisan speeches over time. The analysis further reveals how competing policy frames and a salient focusing event shaped congressional and public discourse, leading to subsequent changes in attention. Taken together, the findings broaden our understanding of the policy process by identifying the specific forces behind the entry and exit of issues on the policy‐making agenda.     

The Formal Delegation of Regulatory Decisions in the Telecommunication Sector: An Explanation Using Classification Trees

Research on regulation has traditionally focused on studying the delegation of regulatory competencies from political principals to an independent regulatory agency. In this article, we argue that this delegation is nuanced by different factors that affect whether a specific regulatory decision is formally delegated. We examine and explain formal delegation patterns at the level of individual regulatory decisions in twelve countries located in Europe, Latin America, and South Asia. The data were gathered by coding the twelve countries' telecommunications legislation. The data analysis was undertaken using a classification tree model—a nonparametric model. We found that the maturity of the market has the greatest effect on the formal delegation of regulatory decisions, but this effect is also influenced by the other theoretical factors considered, particularly the level of political constraints and the type of regulation.     

The Space Between: Demonization of Opponents and Policy Divergence

Prior research on policy conflicts indicates a tendency among policy actors to misperceive the influence of actors engaged in policy debates based on the degree of distance between their relative policy positions. This research develops a measure for assessing the degree and direction of the misperception effect. This measure is then utilized as a dependent variable to assess the relationship between theoretically relevant factors and the degree to which actors will exaggerate the influence of their opponents and allies. The research uses original survey data of policy actors engaged in the debate over hydraulic fracturing in New York. The results indicate misperceptions of relative influence are prevalent and most associated with the experience of a policy loss and holding relatively extreme policy beliefs. The findings provide new insight into factors that influence the demonization of political opponents. These insights are timely in the context of polarized debates over environmental and energy policy in the United States.     

Molecular Identification of Necrophagous Dermestes Species in South Korea Using Cytochrome c Oxidase Subunit I Nucleotide Sequences (Genus Dermestes)

Species identification of necrophagous insects found on a dead body is an essential key in applying medicolegal entomology to the estimation of postmortem interval (PMI). Due to limited morphological identification of insect evidence, several studies have identified species using molecular information such as DNA markers. While considerable cytochrome c oxidase subunit I (COI) gene sequence data of necrophagous fly species have been collected and annotated, those of necrophagous beetle species have not. Since necrophagous beetles such as Dermestes species have a larval period longer than that of flies, beetles are useful in even the late decomposition phase in estimating minimum PMI. To obtain the full-length COI gene sequences of six Dermestes species collected from South Korea, we designed primers for polymerase chain reaction amplification and sequencing. The obtained full COI nucleotide sequences were used for performing phylogenic analysis and comparison with previously reported sequences. The results demonstrated that the COI gene sequences could be used to identify forensically important Dermestes species in South Korea.
