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
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
Development of a geovisor for the multi-temporal analysis of deforestation in the Tinigua National Natural Park in the periods 2016, 2020 and 2024, through supervised classification with GIS tools
No full textUna de las grandes problemáticas ambientales que avanza en Colombia a grandes pasos es la deforestación, una de las áreas afectadas por este fenómeno es el Parque Nacional Natural Tinigua, localizado en el departamento del Meta. Las deforestaciones impulsadas por actividades humanas tales como talas ilegales, el sector minero y la principal expansión agrícola, ha puesto en peligro este frágil ecosistema. Es por esto que surge la necesidad de realizar un análisis multitemporal para los años 2016,2020 y 2024 que permita estudiar y evidenciar los cambios en la cobertura vegetal del parque Tinigua utilizando sistemas de
información geográfica (SIG) y herramientas de análisis espacial proporcionadas por Esri, como lo son, ArcGIS Pro y ArcGIS Online, para realizar una clasificación supervisada de imágenes satelitales obtenidas de Landsat 8. Además de esto la generación de un geovisor permitirá realizar una exploración de manera interactiva y fácil sobre los resultados de la clasificación donde se observará el aumento de la deforestación lo largo del tiempo, así como la identificación de áreas críticas de pérdida de cobertura forestal, gráficos estadísticos que permitirán una mayor comprensión de los resultados para futuros análisis.One of the major environmental issues progressing rapidly in Colombia is deforestation. One of the areas affected by this phenomenon is the Tinigua National Natural Park, located in the department of Meta. Deforestation driven by human activities such as illegal logging, the mining sector, and major agricultural expansion has endangered this fragile ecosystem. Therefore, there is a need for a multi-temporal analysis for the years 2016, 2020, and 2024 to study and highlight changes in the vegetation cover of Tinigua Park. This will be achieved using geographic information systems (GIS) and spatial analysis tools provided
by Esri, such as ArcGIS Pro and ArcGIS Online, to conduct a supervised classification of satellite images from Landsat 8. Additionally, the creation of a geoviewer will allow for an interactive and accessible exploration of the classification results, showing the increase in deforestation over time, as well as identifying critical areas of forest cover loss, with statistical graphs that will provide a better understanding of the results for future analyses.Especializació

Good practices in the use of geoespatial databases "GDB" for environmental projects
No full textEl presente artículo aborda la importancia y metodología de implementar buenas prácticas en la gestión de bases de datos geoespaciales (GDB) en proyectos ambientales. Tener un correcto uso de una GDB es esencial para mantener la integridad y precisión de los datos. Se subraya la necesidad de coherencia entre la GDB y los informes asociados, para asegurar el cumplimiento de los requisitos normativos establecidos por la Autoridad Nacional de Licencias Ambientales (ANLA). La ANLA utiliza una geodatabase propietaria de ESRI, conocida como GDB, para gestionar la información geoespacial en proyectos ambientales. Las resoluciones emitidas por el Ministerio de Ambiente y Desarrollo Sostenible proporcionan las directrices específicas para la presentación y evaluación de estudios ambientales.
Al identificar y evaluar las fuentes de información, la recopilación de datos secundarios, y el diseño y aplicación de encuestas a profesionales expertos en GDB, se verán resultados y discusiones destacando la importancia de la coherencia entre la GDB y los informes, la revisión exhaustiva de la GDB, y el manejo adecuado de la topología para asegurar la calidad de los datos.
Por tanto, la implementación de buenas prácticas en el uso de GDB, junto con la capacitación constante del personal y el uso de guías actualizadas, mejora la integridad de los datos y facilita la toma de decisiones en proyectos ambientales, asegurando el cumplimiento de los requisitos legales y normativos.This article approach the importance and methodology of implementing good practices in the management of geospatial databases (GDB) in environmental projects. Having correct use of a GDB is essential to maintain the integrity and accuracy of the data. The need for coherence between the GDB and the associated reports is highlighted, to ensure compliance with the regulatory requirements established by the National Environmental Licensing Authority (ANLA). ANLA uses a proprietary ESRI geodatabase, known as GDB, to manage geospatial information in environmental projects. The resolutions issued by the Ministry of Environment and Sustainable Development provide specific guidelines for the presentation and evaluation of environmental studies.
