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
The role of formation and beliefs in the development of the professorality of polyvalent teachers for the teaching of mathematics
No full textThis dissertation is the result of a qualitative research carried out in the Graduate Program in Teaching of Sciences and Mathematics - Professional Master's Degree at the Federal University of Pelotas, which had as a general objective to identify the development of the professorality of polyvalent teachers, specifically, regarding the teaching of Mathematics in the initial years. The research question for this work was: "what is the role of formation and beliefs about teaching mathematics in the the development of the professorality of polyvalent teachers, whose task is to teach mathematical content in the early years?" This study originated of acting of the researcher as scholarship student of institutional program of fellowships of initiation teaching during graduation, acting in the subproject "Mathematics in the initial years" in a school of the municipal public network of Pelotas. The subjects of this investigation were five multipurpose teachers, that is, teachers of the first years of elementary school of this school. The research was developed through a case study, because it is believed that this way it is possible to analyze deeply the researched situation. In order to account for the study, a questionnaire with open questions was applied in order to know the subjects of the research, in addition, semi-structured interviews were conducted and two other instruments were used: Mathematical biography and numbering line. Discursive Textual Analysis was used to analyze the data collected. Based on the results obtained in the study it is possible to affirm that the professorality is developed from situations that permeate the life of teachers, among which, in this study, the beliefs and initial formation that play a fundamental role in this process stand out. It can also be identified that the initial training courses that these teachers experienced did not allow favorable conditions for learning mathematical concepts, which will be necessary for teachers in their pedagogical practices.Esta dissertação é resultado de uma pesquisa qualitativa realizada no Programa de Pós-Graduação em Ensino de Ciências e Matemática – Mestrado Profissional na Universidade Federal de Pelotas, que teve por objetivo geral identificar o desenvolvimento da professoralidade de professoras polivalentes, em específico, no que se refere ao ensino de Matemática nos anos iniciais. A questão da pesquisa para este trabalho foi: “qual o papel da formação e das crenças sobre ensino de Matemática no desenvolvimento da professoralidade de professoras polivalentes, as quais têm como tarefa ensinar conteúdos matemáticos nos anos iniciais?”. Este estudo originou-se da atuação da pesquisadora como bolsista no Programa Institucional de Bolsas de Iniciação à Docência, durante a graduação, atuando no subprojeto “Matemática nos anos iniciais” numa escola da rede pública municipal de Pelotas. Os sujeitos desta investigação foram cinco professoras polivalentes, ou seja, professoras dos primeiros anos do ensino fundamental desta escola. A pesquisa foi desenvolvida por meio de estudo de caso, pois acredita-se que assim é possível analisar profundamente a situação pesquisada. Para dar conta do estudo foi aplicado um questionário com questões abertas, a fim de conhecer os sujeitos da pesquisa, além disso, foram realizadas entrevistas semiestruturadas e usados outros dois instrumentos: biografia Matemática e linha do numeramento. Utilizou-se da Análise Textual Discursiva para análise dos dados coletados. Com base nos resultados obtidos no estudo é possível afirmar que a professoralidade é desenvolvida a partir de situações que permeiam a vida das docentes, dentre as quais, neste estudo, destacam-se as crenças e a formação inicial que desempenham um papel fundamental nesse processo. Pode-se identificar, ainda, que os cursos de formação inicial que essas professoras vivenciaram não possibilitaram condições favoráveis para aprendizagem de conceitos matemáticos, os quais serão necessários às professoras em suas práticas pedagógicas
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
