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
Mind the Gap: Cómo los medios de comunicación en Colombia moldean a la brecha de género
No full textEn aquest article, analitzem el contingut dels articles de premsa per identificar biaixos de gènere en el llenguatge utilitzat pels mitjans digitals a Colòmbia. Utilitzem tècniques modernes de mineria de textos per recopilar i analitzar publicacions de diaris que esmenten paraules clau relacionades amb el gènere i estudiar-les en detall. També abordem els biaixos de gènere cap als migrants analitzant articles de notícies relacionats amb els immigrants veneçolans mitjançant un enfocament de gènere. Els nostres resultats indiquen que els diaris es refereixen a les dones utilitzant paraules relacionades amb el seu paper com a cuidadores, mentre que utilitzen paraules relacionades amb la inseguretat i la delinqüència quan parlen d'homes. Tot i que els termes i sentiments positius són comuns quan es refereix a ambdós gèneres, els negatius s'utilitzen amb més freqüència quan s'esmenten els homes, sovint centrant-se en el comportament agressiu i les detencions policials. Els articles sobre migrants veneçolans se centren en el seu procés migratori, benestar i condicions laborals. No obstant això, trobem biaixos de gènere. Els articles sobre dones migrants sovint parlen de pobresa i sexualitat, mentre que els d'homes se centren en la il·legalitat. El nostre estudi destaca la necessitat de prestar més atenció als biaixos de gènere en els mitjans de comunicació, especialment pel que fa a les poblacions migrants.In this paper, we analyze the content of press articles to identify gender biases in the language used by the digital media in Colombia. We employ modern text mining techniques to collect and analyze newspaper publications that mention gender-related keywords and study them in detail. We also address gender biases towards migrants by analyzing news articles related to Venezuelan immigrants using a gender approach. Our findings indicate that newspapers refer to women using words related to their role as caregivers, while using words related to insecurity and crime when discussing men. Although positive terms and feelings are common when referring to both genders, negative ones are more frequently used when mentioning males, often focusing on aggressive behavior and police arrests. Articles about Venezuelan migrants focus on their migratory process, welfare, and labor conditions. However, we find gender biases. Pieces about women migrants frequently discuss poverty and sexuality, while those about men focus on illegality. Our study highlights the need to pay more attention to gender biases in the media, particularly regarding migrant populations.En este trabajo se analiza el contenido de artículos de prensa para identificar sesgos de género en el lenguaje utilizado por los medios digitales en Colombia.

También abordamos los sesgos de género hacia los migrantes mediante el análisis de noticias relacionadas con los inmigrantes venezolanos desde un enfoque de género. Nuestros hallazgos indican que los periódicos se refieren a las mujeres utilizando palabras relacionadas con su papel como cuidadoras, mientras que utilizan palabras relacionadas con la inseguridad y la delincuencia cuando hablan de hombres. Aunque los términos y sentimientos positivos son comunes cuando se refieren a ambos géneros, los negativos se utilizan con mayor frecuencia cuando se menciona a los hombres, a menudo centrándose en el comportamiento agresivo y los arrestos policiales. Los artículos sobre los migrantes venezolanos se centran en su proceso migratorio, su bienestar y sus condiciones laborales. Sin embargo, encontramos sesgos de género. Las piezas sobre mujeres migrantes suelen hablar de la pobreza y la sexualidad, mientras que las de hombres se centran en la ilegalidad. Nuestro estudio destaca la necesidad de prestar más atención a los sesgos de género en los medios de comunicación, especialmente en lo que respecta a las poblaciones migrantes
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
