Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Renewable gases fueling the energy transition in residential heating and private transportation: A multi-perspective approach
This dissertation examines the role of renewable gases - biomethane and synthetic natural gas (SNG) - in Germany's energy transition, focusing on the residential heating and private transportation sectors. The research is grounded in a coevolutionary approach, that emphasizes socio-technical system transitions, and draws on theories of consumer decision-making and energy policy design. A mixed-methods approach underpins this work: qualitative analyses explore policy frameworks and consumer perceptions, while quantitative Discrete Choice Experiments investigate consumer preferences and willingness-to-pay (WTP).
Empirically, the five articles of this cumulative dissertation highlight critical findings. Policies favor renewable gases in electricity and transportation, leaving heating markets underdeveloped, with biomethane adoption largely driven by regulatory mandates. Consumer decisions in these markets are marked by low involvement, limited awareness, and significant price sensitivity. Nevertheless, there is notable willingness to pay for renewable gas products, particularly SNG, though this willingness often fails to match higher production costs. The four articles are structured into two parts. The first part explores the policy and market structures shaping renewable gas uptake, including an analysis of tariff offerings and the regulatory landscape. The second part delves into consumer behavior, with articles assessing perceptions, preferences, and pricing dynamics for biomethane and SNG. Collectively, this dissertation advances the literature on energy transitions, consumer behavior, and renewable gas market integration, offering actionable insights for policymakers, market stakeholders, and researchers
Are voluntary markets effective in replacing state-led support for the expansion of renewables? A comparative analysis of voluntary green electricity markets in Germany, the UK, France and Italy
With state-led support being only temporary, attention has turned to retail electricity markets to provide long- term support for renewable electricity. Past research has focused on consumer preferences for green elec-tricity, i.e. the demand side. We investigated the supply side by analyzing what suppliers selling green retail electricity products in the UK, Germany, France and Italy actually provide. Through content analysis of the online data provided by these companies, we found that most products in Germany and France rely on Scan-dinavian hydropower. Since almost all of these plants have been operating for decades, these products today cannot be said to effectively drive new renewable capacities. Products in the UK and Italy rely on sources which already have state-led support and thus also do not drive the expansion of renewables. In fact, none of the four countries has established a policy framework that successfully fosters the development of a voluntary market for green electricity capable of driving the expansion of renewables. Alignment between sustainable energy policy objectives, consumer demand, and supply-side offerings in a voluntary market might be improved by empow-ering consumers through a simplified and possibly state-led labeling scheme that focuses on environmental impact and includes minimum standards for performance
