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

Out with jobs and in with skills : measuring current circular jobs and analyzing future necessary skills
No full textAbstract: This dissertation explores the labor market transition in Belgium and Flanders from a linear economic model to a circular economy, focusing on sustainable materials management and its contribution to broader sustainable development goals. It explores new ways to monitor circular jobs and skills, the effects of circular economy strategies on skills, and an impact assessment of the COVID-19 crisis on the circular companies and their employees. Using Natural Language Processing, a General Equilibrium model and a Skills Extension Tool, an attempt is made to quantify circular activities and jobs in Belgium and analyze the impact of circular economy policy measures on jobs and skills. Regression analyses investigate the relationship between circular strategies and skills requirements among startups in Flanders, focusing on transport and logistics, research and development, IT, and technical skills. Lastly, the regression analyses also examine the resilience of companies in Flanders during the COVID-19 crisis in relation to their circularity level. The dissertation underscores the importance of proactive policy measures to support companies in building resilience, and to support employees and educational institutions to acquire the necessary skills, especially during times of crisis
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

Een verkennend onderzoek naar de economische waarde van pyrolyseolie uit korteomloophout
No full textDeze masterproef biedt de lezer een verkennend onderzoek naar de economische waarde van pyrolyseolie. Hoewel er zeer weinig bestaande uitgewerkte toepassingen zijn voor pyrolyseolie, kan het toch voor verschillende doeleinden gebruikt worden. In deze masterproef zijn de toepassingen opgedeeld in drie categorieën: de toepassing als energiebron, de toepassing als grondstof voor chemicaliën en de toepassing als transportbrandstof. Als conclusie kan gesteld worden dat de waarde van pyrolyseolie [246,70-262,14] EUR per ton (95%-BI) bedraagt op basis van een WKK-installatie. Deze waarde kan echter oplopen tot enkele duizenden euro's per ton, indien technologische vooruitgang wordt geboekt bij de scheidingsmethoden (inclusief zuiverheid) van economisch waardevolle chemische componenten uit pyrolyseolie. De productie van transportbrandstoffen uit pyrolyseolie in de Noorderkempen is op basis van de huidige data onmogelijk concurrentieel met conventionele transportbrandstoffen
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
