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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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
Assessing productivity and efficiency, and its determinants : the case of crop farms in Austria
No full textDie landwirtschaftlichen Betriebe in Österreich sind vergleichsweise klein und kämpfen mit naturbedingten Nachteilen. Die Betriebe sind auch heterogen hinsichtlich ihrer Managementfähigkeiten, dem Produktionsumfeld, der Technologie und der Organisationsstruktur. Änderung der Agrarpolitik haben den Druck auf die Betriebe erhöht, effizient zu sein, um langfristig überleben zu können. Die Dissertation untersucht die Produktivität von Ackerbaubetrieben in Österreich, indem sie i) die kurzfristige (transient) und langfristige (persistent) technische Effizienz mit dem „four-component stochastic frontier” Model analysiert, ii) die Rolle der Nebenerwerbslandwirtschaft auf die technische und Skaleneffizienz untersucht und iii) die Determinanten von technischer und Skaleneffizienz bestimmt. Die Analyse basiert auf zwei Stichproben des österreichischen Teils des Informationsnetz Landwirtschaftlicher Buchführung der EU von 2003 bis 2017. Die Ergebnisse zeigen, dass, obwohl Verbesserungen der langfristigen Effizienz möglich sind, die kurzfristigen Ineffizienzen eine größere Herausforderung darstellen. Betriebe mit günstigen natürlichen Bedingungen, einem höheren Anteil an Familienarbeitskräften und einem geringeren Anteil an Landbesitz sind dauerhaft effizienter. Spezialisierung, Größe des Betriebs und das Alter der Betriebsleiter:in sind positiv mit kurzfristiger Effizienz verbunden, während Subventionen negative Auswirkungen haben. Darüber hinaus zeigt die Studie, dass Nebenerwerbsbetriebe skaleneffizienter sind. Die Lücke in der Skaleneffizienz zwischen Nebenerwerbs- und Vollerwerbsbetrieben nimmt über die Zeit zu. Dies zeigt die größere Notwendigkeit von Vollerwerbsbetrieben zu wachsen. Faktoren die das Betriebswachstum fördern (d. h. Zugang zu und niedrigere Kosten für Land, Flexibilität des Arbeitskräfteangebots, höhere Subventionen) erhöhen auch die Skaleneffizienz. Technologischer Fortschritt in Verbindung mit abnehmender technischer Effizienz weisen auf einen divergierenden Sektor hin, in dem einige Betriebe ihre Produktivität steigern, während andere zurückfallen.Farms in Austria are comparatively small and face natural disadvantages. They are also diverse regarding managerial skills, production environment, technology and organisational structure. Changes in agricultural policies have increased the pressure on farmers to be efficient, productive, and competitive to survive and remain in business in the long term. The thesis assesses the productivity of crop farms in Austria by i) analysing their transient (time-varying) and persistent (time-invariant) technical efficiency using the four-component stochastic frontier model, ii) investigating the role of part-time farming on technical and scale efficiency, and iii) examining the determinants of technical and scale efficiency. The analysis is based on two samples from the Austrian fraction of the EU's Farm Accountancy Data Network (FADN) from 2003 to 2017, focusing on specialised field crop farms. Results show that, although improvements in persistent efficiency are still possible, transient inefficiency poses a greater challenge to farms. Favourable natural conditions, a higher share of family labour, and a lower share of owned land increase persistent efficiency. Farm specialisation, size, and farmers' age are positively associated with transient efficiency, while subsidies have adverse impacts. Although no significant difference in technical efficiency between part-time and full-time farms is observed, part-time farms are more scale-efficient. This gap in scale efficiency between part-time and full-time farms increases over time, indicating the higher necessity of full-time farms to grow. The analysis of the determinants confirms that factors facilitating farm growth (i.e., access to and lower costs of land, flexibility of labour supply, and higher subsidies) also increase scale efficiency. Technological progress coupled with decreasing technical efficiency indicates a diverging sector, where some farms increase productivity and competitiveness while others fall behind.submitted by Felicity AddoKumulative Dissertatin aus zwei ArtikelnDissertation Universität für Bodenkultur Wien 2023Mit deutscher Zusammenfassun

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
