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
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
Desórdenes temporomandibulares como factor etiológico de maloclusiones: revisión sistemática.
No full textEl dolor, los ruidos articulares, las desviaciones mandibulares y el daño en la función masticatoria son las quejas más comunes por las cuales se consulta al especialista. Los desórdenes temporomandibulares (DTM) son alteraciones que deben evaluarse en los pacientes que buscan tratamiento de ortodoncia, debido a la relación anatómica que presentan la articulación temporomandibular(ATM) y la oclusión. estos desórdenes pueden explicar estos cambios dinámicos (alteraciones estructurales, funcionales y psicológicas). El objetivo de esta revisión es definir la asociación entre DTM y maloclusión, además de estructurar un protocolo de manejo ortodóncico basado en la evidencia. Materiales y métodos: Se realizó la búsqueda en las bases de datos (PubMed, Scopus y google scholar) de 2010 a 2019 con términos MeSH tales como “TMD” (temporomandibular disorders), “maloclussion”, “orthodontics”, “TMJD”,” craniomandibular disorders” y “osteoarthritis” además de operadores booleanos. Fueron seleccionados 166 artículos, 36 duplicados y 130 artículos se localizaron. 23 artículos se seleccionaron para la presente revisión. Resultados: Los DTM afectan al paciente desde etapas tempranas hasta la edad adulta, siendo un factor etológico de maloclusión en los tres planos del espacio. Conclusión: las maloclusiones agudas y crónicas son el resultado de alteración muscular, enfermedad degenerativa condilar y trauma. El ortodoncista debe conocer el protocolo para tratar estas alteraciones oclusales. Una adecuada anamnesis en la consulta inicial, un examen físico y recopilación de los signos clínicos pueden ser el gold standard para realizar un correcto diagnóstico y un tratamiento exitoso.Pain, temporomandibular joint noises, mandibular deviations and damage to masticatory function are the most common complaints for which the specialist is consulted. Temporomandibular disorders (TMD) are alterations that should be evaluated in patients seeking orthodontic treatment, due to the anatomical relationship between the temporomandibular joint (TMJ) and occlusion. these disorders can explain these dynamic changes (structural, functional and psychological alterations). The objective of this review is to define the association between TMD and malocclusion, in addition to structuring an evidence-based orthodontic management protocol. Materials and methods: the search was performed in the databases (PubMed, Scopus and google scholar) from 2010 to 2019 with MeSH terms such as "TMD" (temporomandibular disorders), "maloclussion", "orthodontics", "TMJD",” Craniomandibular disorders” and “osteoarthritis” in addition to boolean operators. 166 articles were selected, 36 duplicates and 130 articles were located. 23 articles were selected for the present review. Results: TMD affect the patient from early stages to adulthood, being an ethological factor of malocclusion in the three planes of space. Conclusion: acute and chronic malocclusions are the result of muscular alteration, condylar degenerative disease and trauma. The orthodontist must know the protocol to treat these occlusal disorders. An adequate anamnesis at the initial consultation, a physical examination and compilation of clinical signs can be the gold standard for making a correct diagnosis and successful treatmenthttps://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001374637https://orcid.org/0000-0001-7329-2663jorge.bernalf@[email protected]
