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
Analytical Study of Lanolin as Potential Biomarker of Prehistoric Sheep‐Shearing Practice
Get PDFSheep-shearing practices probably started in the Neolithic Age when the genetic selection of sheep began to be successful in obtaining animals with abundant wool. Flint and obsidian were the main materials probably used to manufacture tools for this purpose. From shearing, lanolin wax is accumulated onto the shearing tools. Lanolin is a complex mixture of esters and polyesters, alcohols, fatty acids, and hydrocarbons produced mainly by sheep to protect the skin and the wool from environmental agents. Due to its complex chemistry, lanolin is relatively difficult to characterize. This work investigates the possible use of lanolin as a biomarker of sheep-shearing practices in the prehistoric era. For this purpose, lanolin degradation pathways have been studied by an experimental archeology approach adjuvated by Fourier transformed infrared spectroscopy, hyperspectral imaging, and gas chromatography coupled with mass spectrometry
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
Plan de negocio de la start-up tecnológica: MyRezeipt
Get PDFGrado en Administración y Dirección de Empresas y Grado en Relaciones InternacionalesEl propósito de este trabajo es analizar el modelo de negocio de una start-up tecnológica, MyRezeipt. Se realizará siguiendo la estructura de un Business Model Canvas, con el apoyo de la incubadora online Bridge4Billions, herramienta proporcionada por la Universidad Pontificia de Comillas.
Inicialmente se hará una descripción de la propuesta de valor de MyRezeipt incluyendo dentro de la misma, los problemas que resuelve para los diferentes segmentos de clientes y usuarios propuestos, un análisis de oportunidades de cada uno de los productos en función a los diferentes segmentos de clientes y por último un análisis de los competidores.
Posteriormente, se analizarán las alianzas estratégicas divididas en dos apartados externas e internas, y se observará la relevancia que tienen para MyRezeipt. Una vez estudiadas las alianzas estratégicas se realizará un plan estratégico apoyado de un análisis del entorno, seguido por el plan de impacto y el plan de marketing.
Los canales de distribución y las relaciones de los clientes se analizarán previamente a realizar el plan financiero donde se verán tres posibles escenarios y se compararán en los diferentes estados financieros para observar la rentabilidad financiera de MyRezeipt.
A modo de conclusión, se podrá observar el Business Model Canvas completado con la información recabada a lo largo del proyecto.The purpose of this project is to analyze the business model of a technological start-up, MyRezeipt, which will be carried out following the structure of a Business Model Canvas, with the help of the online incubator Bridge4Billions, a tool provided by the Comillas Pontifical University.
Initially, a description of MyRezeipt's value proposal will be made, including within it, the problems it solves for the different customer and user segments proposed, an opportunity analysis of each of the products according to the different customer segments and finally an analysis of the competitors.
Afterwards, the strategic alliances will be analyzed, divided in two external and internal sections, in order to remark the relevance, they have for MyRezeipt. Once the strategic alliances have been studied, a strategic plan will be drawn up, supported by an analysis of the environment, followed by the impact plan and the marketing plan.
The distribution channels and customer relationships will be analyzed before making the financial plan where three possible scenarios will be seen and compared in the different financial statements to observe the financial profitability of MyRezeipt.
As a conclusion, it will be possible to observe the Business Model Canvas completed with the information collected throughout the project
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
