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
Estrategia Sectorial de Innovación para el Encadenamiento Productivo
Get PDFCurrently, phenomena such as globalization and the economic interdependence of countries have made the requirements in goods and services in optimal conditions to meet world demand. These requirements have made the economy to be oriented towards the commodities that set the world standard, as is the case of oil and its derivatives. Thus, many companies linked to this sector require a sectorial strategy of innovation in accordance with current needs. One of these strategies is related to maintenance as a fundamental axis to guarantee the operation, that is why fundamental needs arise in the organizations that carry out petrochemical processes, to have suppliers that can satisfy those needs. That is why we propose the design of a sectorial strategy in innovation in the competitive maintenance cluster in order to strengthen the productivity and competitiveness of the organizations and actors that are part of it. The most relevant fndings are linked to gap analysis, evaluation of technological trends and a defnition of a technology management plan and cluster development. This proposal is based on the models of productive chaining and is based on the theories of research and innovation strategies for intelligent specialization RIS3, business innovation capabilities, business strategy.En la actualidad, fenómenos como la globalización y la interdependencia económica de los países ha hecho que los requerimientos en bienes y servicios se encuentren en óptimas condiciones para satisfacer la demanda mundial. Esos requerimientos, han hecho que la economía se oriente hacia los comodities que marcan la pauta mundial como es el caso del Petróleo y sus derivados. Es así como muchas compañías vinculadas a este sector requieren de una estrategia sectorial de innovación acorde con las necesidades actuales. Una de estas estrategias está relacionada con el mantenimiento como eje fundamental para garantizar la operación, es por esto que surgen necesidades fundamentales en las organizaciones que realizan procesos petroquímicos, de contar con proveedores que puedan satisfacer esas necesidades. Es por esto que se propone el diseño de una estrategia sectorial en innovación en el clúster de mantenimiento competitivo con el fn de fortalecer la productividad y competitividad de las organizaciones y actores que hacen parte de este. Los hallazgos más relevantes se vinculan análisis de brechas, evaluación de tendencias tecnológicas y una defnición de plan de gestión de tecnologías y de desarrollo del clúster. Esta propuesta se fundamenta en los modelos de encadenamiento productivo y se basa en las teorías de estrategias de investigación e innovación para la especialización inteligente RIS3, capacidades de innovación empresarial, estrategia empresarial
Análisis de las principales tendencias en torno a las líneas de investigación de los grupos de ingeniería industrial en Colombia
No full textEl objetivo de este trabajo es establecer los lineamientos de un proceso metodológico para la optimización del proceso de construcción y fortalecimiento de líneas de Investigación en los programas de Ingeniería. En la primera parte se presenta una aproximación general a los procesos de búsqueda de información técnica relevante, almacenamiento y procesamiento de la misma para la toma de decisiones, luego se exploran diferentes alternativas de construcción de resultados basados en herramientas estadísticas, e inteligencia artificial; por último se muestran los resultados de un ejercicio aplicado a la ingeniería industrial, los cuales se basan en analizar el estado y resultados de los grupos de investigación a nivel Nacional e Iberoamericano, las tendencias de las líneas de Investigación, sectores de aplicación y publicaciones, con el objetivo de determinar su pertinencia con las necesidades del entorno y así desarrollar políticas y estrategias que apoyen la investigación en las instituciones de educación superio

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
