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
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
Mapping deforestation stages and spatial patterns in the Amazon rainforest using fractal analysis and data mining techniques = Mapeo de las etapas y patrones de la deforestación en el bosque Amazónico usando análisis fractales y mineria de datos
No full textSeveral analyses can be derived from the land-change information provided by remote sensing image datasets. This study was pioneer to examine the stages and spatial patterns of forest loss across the Amazon rainforest according to the information provided by two methodological frameworks (fractal analysis and data mining). These frameworks were tested for analysing two operational deforestation dataset sources (Terra-i and Global Forest Change) at different extent of analysis (four increasing fixed grids sizes). As a result, both frameworks led to different conclusions regarding the dynamics of deforestation in the study area. In the fractal analysis framework, the Global Forest Change (GFC) dataset showed a higher proportion of advanced stages (fractal dimension ranging between 1.00 to 1.64) of deforestation than the Terra-i dataset. Regarding the data mining framework, it suggested the feasibility of artificial neural networks for mapping spatial patterns. The use of this algorithm with an extent of analysis of 30720 m provided the best true model performance using either the GFC or Terra-i datasets (kappa values of 0.73 and 0.70, respectively). In overall, both frameworks indicated some parts of the Amazon rainforest recent deforestation has started to compact as clearings start to agglomerate in medium and large shapes. In terms of agents of forest change, the most dominant spatial pattern typologies point to spontaneous and small agricultural colonisation as the main drivers of recent forest-change dynamics in the study area.
Resumen: Una variedad de información sobre el cambio del uso del suelo y la tierra puede ser derivada de productos generados por imágenes satelitales. Este estudio fue pionero en examinar las etapas y los patrones espaciales de la pérdida de bosques en la selva Amazónica de acuerdo con la información proporcionada por dos marcos metodológicos (análisis fractal y minería de datos). Estos marcos fueron probados para analizar dos fuentes de datos de deforestación (Terra-i y Global Forest Change) en diferentes extensiones geográficas de análisis (cuatro tamaños de cuadrículas fijas crecientes). Como resultado, ambos marcos llevaron a conclusiones diferentes con respecto a la dinámica de la deforestación en el área de estudio. En el enfoque con análisis fractal, el conjunto de datos de Cambio Forestal Global (GFC) mostró una mayor proporción de etapas avanzadas (dimensión fractal que oscila entre 1.00 a 1.64) de deforestación que el conjunto de datos Terra-i. Con respecto al análisis con minería de datos, esté sugirió la viabilidad de redes neuronales artificiales para mapear patrones espaciales. El uso de este algoritmo con un análisis de extensión geográfica de 30.720 m proporcionó el mejor resultado utilizando cualquiera de los conjuntos de datos, GFC o Terra-i (valores kappa de 0,73 y 0,70, respectivamente). En general, ambos enfoques indicaron que algunas partes de la selva tropical Amazónica han comenzado a compactarse recientemente a medida que las talas comienzan a aglomerarse en formas medianas y grandes. En términos de agentes del cambio, las tipologías de patrones espaciales más dominantes apuntan a la colonización agrícola espontánea y pequeña como los principales impulsores de la dinámica reciente del cambio del bosque en el área de estudio

Get PDFkoamabayili/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
