Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Determinants of Regional Economic Growth by Quantile
Get PDFregstdpo-Cuaresma J., Foster N. and Stehrer R. Determinants of regional economic growth by quantile, Regional Studies. The robustness of growth determinants across European Union regions is analysed using quantile regression. Using Bayesian model averaging (BMA) on the class of quantile regression models, it is proposed that the set of relevant covariates is assessed, allowing for different effects across growth quantiles. The results indicate that the robust growth determinants differ across quantiles. The set of robust variables includes physical investment when taking country fixed-effects into account, and skill endowment and initial gross domestic product per capita when not. Even when a variable is found to be robust across quantiles, its estimated impact on growth is often found to vary across quantiles. [image omitted] regstdpo-Cuaresma J., Foster N. et Stehrer R. Les determinants de la croissance economique par quantile, Regional Studies. A partir d'une regression par quantile, on analyse la solidite des determinants de la croissance a travers les regions de l'Union europeenne. Employant un Bayesian Averaging Model (BMA) sur la categorie de modeles de regression par quantile, on propose une evaluation de la covariance, compte tenu des effets differents suivant les quantiles de croissance. L'ensemble de variables solides comprend l'investissement materiel quand on tient compte des effets specifiques a un pays, sinon la dotation en connaissance et le produit interieur brut initial par tete. Meme quand une variable s'avere solide a travers les quantiles, l'impact prevu sur la croissance varie souvent a travers les quantiles. Croissance regionale Bayesian model averaging Regression par quantiles regstdpo-Cuaresma J., Foster N. und Stehrer R. Determinanten regionalen Wachstums nach Quantilen, Regional Studies. In diesem Beitrag wird die Robustheit von Wachstumsdeterminanten in EU-Regionen mittels Quantilsregressionen analysiert. Dabei wird ein Bayesian Model Averaging (BMA) fur Quantilsregressionen verwendet, um die relevanten Kovariaten, die unterschiedliche Effekte in den jeweiligen Wachstumsquantilen aufweisen konnen, zu ermitteln. Die Resultate zeigen, dass die robusten Wachstumsdeterminanten in den jeweiligen Quantilen tatsachlich unterschiedlich sind. Unter Berucksichtigung von landerspezifischen Effekten ist insbesondere die Variable Anlageinvestitionen ein robuster Erklarungsfaktor regionalen Wachstums; ohne Berucksichtigen dieser Effekte sind Humankapitalausstattung und das Pro-Kopf-Einkommen robuste Determinanten. Auch wenn eine bestimmte Variable robust in mehreren oder allen Quantilen ist, sind die ermittelten Effekte auf das Wachstum der Regionen in den jeweiligen Quantilen oftmals unterschiedlich.

Analizamos la solidez de los determinantes de crecimiento en las regiones de la Union Europea usando una regresion cuantilica. Mediante el uso de promedios de modelo bayesiano sobre la clase de los modelos de regresion cuantilica, proponemos que se evalue el conjunto de las covariantes correspondientes teniendo en cuenta los diferentes efectos en los cuantiles de crecimiento. Los resultados indican que los determinantes de un crecimiento solido son diferentes entre los cuantiles. Si se tienen en cuenta los efectos fijos de cada pais, la inversion fisica es una variable fuerte, de no ser asi son variables fuertes la dotacion de habilidades y el producto interno bruto per capita inicial. Incluso cuando se halla una variable que es solida en varios cuantiles, se observa con frecuencia que el impacto estimado en el crecimiento varia entre los cuantiles.

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
