Bridging the Gap: Progress and Prospects for Accelerating South Korea's Move Towards a Carbon Neutral Scenario
No full textThe Moon administration in South Korea has implemented rapid changes to accelerate the decarbonization of the energy sector. While seeking to embrace renewables, Seoul has been relying on the bridging capacity of natural gas—of which it is the world’s third largest importer. In this context, President Moon is also confronted with public discontent over weak emissions goals and inadequate policies to curb the negative effects of climate change. Besides, the socio-economic fallout from the pandemic could hinder the enforcement of environmental measures and loosen restrictions for the sake of an immediate recovery. As Seoul attempts to secure more environmentally-friendly and economically sustainable energy sources, this paper examines the advances and major drawbacks of this policy agenda. By shedding light on the dynamics within the gas sector, the analysis also assesses the viability of liquefied natural gas (LNG) as the pillar of this pro-environmental policy shift, including the potential of some LNG-related projects. The paper finds the feasibility of the current goals is challenged by the realities of energy supply stabilization, particularly due to the simultaneous phaseout of coal and nuclear power and the persistent capacity
obstacles for renewables to fill this gap. In light of this, the paper advocates for integrated policy measures aimed at improving consistency in implementing national energy policy in tandem with climate change mitigation efforts
Chaos at the Gates: The impacts of the COVID-19 pandemic and energy price shocks on South Korea's gas industry amid energy transition
Full text linkSouth Korea was one of the first countries to be hit by the coronavirus infections. Having rapidly contained the health emergency in the immediate period, Seoul arguably mitigated the economic fallouts more successfully than the majority of advanced economies but could not avoid substantial losses. The far-reaching fallout of COVID-19 has been testing the country's energy transition pathway, as actors involved are facing difficult decisions amid more stringent financial constraints to deliver their ambitious targets, including achieving carbon neutrality by 2050. Amid the combined effects of the pandemic and the global energy prices shocks, addressing the nexus between energy security on the supply side, affordability, and the safety of people's lives and property, has become even more pressing. Against this backdrop, natural gas has tailored a special role to bridge the low carbon re-alignment of the entire Korean energy system, also in the face of the current and future challenges to Korea's energy security. But long-drawn hurdles stemming from rather unsuccessful efforts to reform the gas system risk weakening its ability to cope with present uncertainties and heightened volatilities

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
