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
Energy efficiency in buildings analysis through thermal simulation of buildings and advanced interpolation of meteorological data
No full textEl presente proyecto de tesis doctoral se centra en completar la falta de estudios científicos
sobre la interpolación de datos meteorológicos para calibrar las simulaciones térmicas de
edificios. Uno de los aspectos principales es determinar cómo los errores en la obtención
de datos meteorológicos se transmiten a las demandas térmicas de los edificios obtenidas
a través de simulaciones térmicas transitorias, consideradas un buen método para predecir
el consumo energético de los edificios.
Esta tesis doctoral evalúa el desempeño de diferentes técnicas de interpolación y su
aplicación a ubicaciones donde no existen estaciones meteorológicas.
Para el desarrollo del estudio se emplean las redes de estaciones meteorológicas de AEMET
(Agencia Estatal de Meteorología) y MeteoGalicia como fuente de datos meteorológicos,
se han seleccionado las 6 variables meteorológicas recogidas en el manual ASHRAE,
Guideline 14-2002: temperatura, presión, radiación global, humedad relativa, velocidad del
viento y dirección del viento, y se utilizan diferentes tipologías edificatorias para determinar
cómo se transmiten los errores a las demandas térmicas de distintos tipos de edificios
seleccionados (edificio terciario, vivienda unifamiliar y edificio multivivienda en cada uno de
los 3 artículos científicos publicados).
En el primer artículo, el edificio terciario correspondiente a la Biblioteca de Ciencias del Mar
de la Universidad de Vigo, se estudió utilizando los datos de la estación meteorológica
situada en el mismo campus de la Universidad de Vigo, a escasos 250m, comparando los
valores obtenidos a través de la simulación transitoria con los calculados con la estación
meteorológica más cercana, en este caso la del aeropuerto de Vigo, a unos 7,5 km, y
comparándolos también con los datos interpolados de toda la red a nivel gallego de
MeteoGalicia: 3 conjuntos de datos derivados de 3 tipos de interpolaciones mediante
kriging: Ordinary Kriging (OK), Universal Kriging (UK) con 3 predictores (longitud, latitud y
altura) y Universal Kriging con 4 predictores (longitud, latitud, altura y distancia a costa).
En el segundo artículo, una vivienda unifamiliar se “desplazó” sucesivamente por 18
ubicaciones de la provincia de Pontevedra, estudiando su respuesta a las interpolaciones
de datos meteorológicos mediante cuatro métodos: Ordinary Kriging, Universal Kriging con
tres predictores (longitud, latitud y altura), Universal Kriging con cuatro predictores
(longitud, latitud, altura y distancia a costa)y Thin Plate Splines (TPS) y enfrentándolos a los
datos de la estación meteorológica más cercana (Nearest Neighbourhood - NN) en cada
una de las ubicaciones. Estudiándose los resultados tanto de las interpolaciones de datos
meteorológicos como de las simulaciones térmicas transitorias, mediante tablas de
resultados.
En el tercer artículo el edificio seleccionado es un edificio multivivienda de 8 plantas.
Moviéndolo sucesivamente por 70 ubicaciones en Galicia, que son las ubicaciones donde la red meteorológica de MeteoGalicia dispone de estaciones donde están disponibles datos
de las 6 variables meteorológicas estudiadas. En este tercer artículo se compararon los
resultados obtenidos utilizando la estación meteorológica más cercana (NN) con el método
de interpolación mediante TPS, y los datos obtenidos, tanto en las interpolaciones de
variables meteorológicas como de las simulaciones térmicas transitorias, se visualizaron y
compararon mediante tecnología de mapeo SIG (Sistemas de Información Geográfica), en
este caso mediante el software QGIS. Se empleó esta tecnología ya que, al tratarse en este
caso de 70 ubicaciones, el manejo de tablas de datos se complica debido a su extensión.
Los datos meteorológicos son críticos para una simulación térmica adecuada, ya que
constituyen las condiciones de contorno del edificio y no siempre están disponibles en la
ubicación exacta del edificio y, por lo tanto, los datos de la estación meteorológica más
cercana, que se pueden encontrar a kilómetros de la ubicación en estudio, se utilizan de
forma extendida.
Para las simulaciones térmicas se emplea el software TRNSYS (Transient System Simulation
Tool) como motor de cálculo de las demandas térmicas de los edificios elegidos. La eficacia
de las distintas técnicas de interpolación se evalúa durante un año sobre una base de datos
horaria.
Los resultados de la comparación de los diferentes métodos de interpolación muestran que
no todas las variables climáticas tienen la misma influencia en los resultados de las
simulaciones térmicas, y que mediante la interpolación de datos meteorológicos se
disminuyen los errores en la obtención de las demandas térmicas de las tipologías
edificatorias analizadas mediante simulación térmica transitoria, frente a las técnicas
utilizadas actualmente de forma más extendida.Este proxecto de tese de doutoramento baséase na falta de estudos científicos sobre a interpolación de datos meteorolóxicos para calibrar simulacións térmicas de edificios. Un dos principais aspectos é determinar como erros na obtención de datos meteorolóxicos son transmitidos ás esixencias térmicas de edificios obtidos a través de simulacións térmicas transitorias, considerado un bo método para prever o consumo de enerxía dos edificios.
Esta tese avalía o rendemento de diferentes técnicas de interpolación ea súa aplicación en lugares onde non hai estacións meteorolóxicas.
Para este estudio se empregan as redes de estacións meteorolóxicas AEMET (Axencia Estatal de Meteoroloxía) e MeteoGalicia como fonte de datos meteorolóxicos, e diferentes tipos de construción son usados para determinar como os erros son transmitidos ás esixencias térmicas de distintos tipos de edificios seleccionado.
Os datos meteorolóxicos son fundamentais para a simulación térmica axeitada, pois constitúen as condicións de contorno do edificio e non sempre están dispoñibles na localización exacta do edificio e, polo tanto, os datos da estación meteorolóxica máis próxima, que se pode atopar en quilómetros do estudo de localización que utilizaban forma estendida.
O software TRNSYS é usado como un motor de cálculo das esixencias térmicas dos edificios escollidos. A eficacia de diferentes técnicas de interpolación para un ano é valorada en base a datos en tempo.
Os resultados da comparación de distintos métodos de interpolación demostrar que non todas as variables meteorolóxicas teñen a mesma influencia sobre os resultados das simulacións térmicas, e interpolando erros de datos meteorolóxicos son reducidos na obtención de demandas térmicas tipo de construción analizados por simulación térmica transiente, en comparación coas técnicas correntemente utilizados máis amplamente.The present dissertation project is based on the lack of scientific studies on the interpolation of meteorological data to calibrate the thermal simulations of buildings. One of the main aspects is to determine how errors in obtaining meteorological data are transmitted to the thermal demands of buildings obtained through transient thermal simulations, considered a good method to predict the energy consumption of buildings.
This doctoral thesis evaluates the performance of different interpolation techniques and their application to locations where there are no meteorological stations.
For the development of the study the networks of meteorological stations of AEMET (Meteorological Agency of State) and METEOGALICIA as meteorological data source are used, and different types of buildings are used to determine how the errors are transmitted to the thermal demands of different types of buildings Selected.
The meteorological data are critical for adequate thermal simulation because they constitute the boundary conditions of the building and are not always available in the exact location of the building and therefore the data of the nearest meteorological station that can be found In kilometers of the study location, are used extensively.
For thermal simulations, the TRNSYS (Transient System Simulation Tool) software is used as the calculation engine for the thermal demands of the chosen buildings. The efficiency of the different interpolation techniques is evaluated over a year on an hourly basis.
The results of the comparison of the different interpolation methods show that not all climatic variables have the same influence on the results of the thermal simulations, and that through the interpolation of meteorological data the errors in obtaining the thermal demands of The building typologies analyzed by means of transient thermal simulation, compared to the techniques currently used in a more widespread way.Ministerio de Economía y Competitividad de España | ENE2015-65999-C2-1-RGobierno de España | IDI-201505050
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
