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
Enunciação e discurso : a linguagem de programação Logo no discurso do afasico
Get PDFOrientador: Maria Irma Hadler CoudryDissertação (mestrado) - Universidade Estadual de Campinas, Instituto de Estudos da LinguagemResumo: O objetivo principal deste estudo é mostrar a pertinência do uso da linguagem de programação Logo Gráfico como protocolo de avaliação e seguimento de sujeitoscom dificuldades lingüístico-cognitivas,tomando como referencial teórico uma concepção enunciativo-discursiva de linguagem. Assim,interessa o trabalho realizado pelo sujeito,o
processo que ele desenvolve, por meio da interlocução (com o computador e com o investigador) que se dá na própria avaliação. Subjacente à escolha do referencial teórico e ao tipo de aplicação a que o Logo se destina está o suposto que a linguagem natural tem uma participação fundamental na atividade de programação Logo. Por meio de atividades inter-relacionadas baseadas no uso da linguagem Logo, desenvolve-se uma avaliação com um sujeito com afasia semântica, sintomas de apraxia vísuo-construtiva e vísuo-espacial com o objetivo de analisar a relação entre a linguagem do sujeito e o modo como ele se organiza espacialmente por meio de uma atividade que requer construção. Características importantes do Logo como, comandos pragmaticamente informados (e redefiníveis) ,interatividade (que pressupõe alternância de interlocutores) e aplicação de noções espaciais, foram fundamentais para sua eleição como instrumento
de avaliação. Os resultados mostram que o uso discursivo da linguagem Logo, compreendido como uma prática discursivarealizada por interlocutores que relaciona o uso cognitivo e social da linguagem, revela-se um importante espaço de produção de linguagem provocando a emergência de processos verbais e não verbais, bem como de suas relações, dando visibilidade ao trabalho lingüístico-cognitivodo sujeitoAbstract: Themain objective of this study isto show the pertinence of the use of the Graphic Logo programming language as evaluation and longitudinal follow up protocol of subjects with linguistic-cognitive difficulties, taking as theoretical referencial an enunciativodiscursive conception of language. Therefore the study is focused on the work accomplished by the subject, the process that he develops, through the dialogue (with the computer and with the investigator) that takes place in the evaluation. Underlying the choice of the theoretical referencial and the kind of application of Logo used is the supposition that natural language has a fundamental participation in programming activity. Through interrelated activities based on the use of Logo, an evaluation was developded with a subject with semantic aphasia, symptoms of visual-constructive and visual-spatialapraxia with the objective of analyzing the relationship between the subject's language and the way he accomplishes an activity that requiresconstruction using spacial notions. Important characteristics of Logo such as commands informed pragmatically (and
that can be redefined), interactivity (that presupposes interlocutor alternation) and application of space notions, were fundamental for its selection as an evaluation instrument. The results show that the discursiveuse of Graphic Logo programming language, understood as a discursive practice accomplished by interlocutors that relate the cognitive and social use of language, can be an important part of language production, provoking the emergence of verbal and non- verbal processes, as well as their relationships,giving visibility to the subject's linguistic-cognitiveworkMestradoMestre em Linguístic
Magical agenda
Get PDFOrientador: Maria Irma Hadler CoudryTese (doutorado) - Universidade Estadual de Campinas, Instituto de Estudos da LinguagemResumo: Este estudo tem como ponto de partida o referencial teórico formulado por Coudry (1986/88) para a área de Neurolingüística que articula a dimensão histórica, intersubjetiva e psíquica da linguagem em função de questões teóricas e metodológicas que repercutem na prática clínica, especialmente no que se refere à relação entre teoria e dado. Trata-se de um trabalho de caráter clínico tanto pela investigação que se propõe a desenvolver quanto pela descrição de procedimentos e práticas com e sobre a linguagem usados no acompanhamento longitudinal de um sujeito de 30 anos do sexo masculino (AL), que apresenta um quadro de Síndrome Frontal leve em virtude de um traumatismo craniano que acometeu bilateralmente os lobos frontais e o lobo parietal alto à direita.
No estudo clínico são considerados os múltiplos fatores pré e pós-episódio neurológico que explicam a heterogeneidade do quadro semiológico de AL: a suposta dislexia diagnosticada na 7ª série do ensino fundamental, o histórico de alcoolismo, o traumatismo crânio-encefálico, a síndrome frontal e as fabulações. Os sintomas que decorrem do quadro se manifestam de maneira discreta o que implica lidar com a estreita relação entre normal/patológico e com a instabilidade que lhe é característica. O sujeito foi acompanhado longitudinalmente entre abril de 2003 e outubro de 2004 no Laboratório de Neurolingüística (LABONE) do Instituto de Estudos da Linguagem (IEL) da Unicamp, para onde foi encaminhado para avaliação neurolingüística em fevereiro de 2002 com queixa de dificuldade de aprendizagem e de leitura e com queixa pessoal de memória. Por meio de achados e indícios que se apresentam em meio à situação clínica - que tem como fio condutor a escrita na Agenda Mágica como lugar de reconstrução da relação do sujeito com a escrita e com a sua subjetividade ¿ são estudadas as relações entre linguagem, memória, corpo e percepção, a partir da articulação das formulações de Freud sobre o funcionamento neurofisiológico do aparelho psíquico, os estudos de Jakobson a respeito do funcionamento bipolar da linguagem e as formulações de Luria sobre a organização sistêmica e hierarquizada das funções cerebraisAbstract: This study has, as starting point, the theoretic referential formulated by Coudry (1986/88) for the area of Neurolinguistics that articulates the historical, inter-subjective and psychic dimension of the language in function of theoretical and methodological questions that re-echo in the practical clinic, especially to the relation between theory and data. It is a work of clinical character such as the inquiry proposed to be developed, as the description of procedures and practices with and about the language used in the longitudinal accompaniment of 30 years old man (AL) that presents a Frontal Syndrome picture due to a brain damage that affected his frontal lobes bilaterally and his parental upright lobe. In the clinical study multiple neurological prior and after episode factors are considered that explain the heterogeneity of AL¿s picture: the supposed dyslexia diagnosis on the seventh grade of basic school, the history of alcoholism, the traumatic brain injury, the frontal syndrome and the fantastical narratives. The symptoms related to the picture reveal in a discrete way what implies dealing with the narrow relation between normal/pathological and with its characteristic instability. The individual was followed longitudinally from April 2003 to October 2004 at the Neurolinguistic Laboratory (LABONE) of Unicamp¿s Institute of Language Studies (IEL), to where he was guided for neurolinguistic evaluation in February 2002, with complaints of difficulty on learning and reading and personal memory complaint. Based on findings and clues present in the clinical situation - that has as conducting wire the writing in the Magical Agenda as a place of reconstruction of the relation between the individual to the writing and its subjectivity - are studied the relations between language, memory, body and perception, from the joint of Freud¿s formularizations about neurophysiological psychic device, Jakobson¿s studies regarding the bipolar functioning of the language and the Luria¿s formulations on the systemic and hierarchically cerebral functions organizationDoutoradoNeurolinguisticaDoutor em Linguístic
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
