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
Análise de uma intervenção pedagógica sobre o tema “fontes de energia” com enfoque em ciência, tecnologia, sociedade e ambiente: possibilidades para o desenvolvimento de competências e habilidades
Get PDFThe research presented here aimed to analyze the skills manifested by first and
second year high school students when a Didactic Sequence (SD) occurred in the
form of a pedagogical intervention based on the Science-Technology-SocietyEnvironment (CTSA) relationship. thematic “Energy Sources”. Based on the
perspective of CTSA references, a pedagogical intervention on the subject was
carried out with a total of 42 students from a secondary and technical school. After
the development of the DS, the students' productions and speeches were analyzed
based on the skills and abilities available in the official curricular documents of
Natural Sciences and its Technologies in High School, the Common National
Curriculum Base (BNCC). The results demonstrate that all records expressed at least
one skill, some very coherent with the proposed theme, others more general,
however, all in relation to the CTSA. They were manifested mainly related to the
theme of Energy Sources, and it is possible to relate the abilities manifested with the
SD's CTSA approach. The skill that presented the highest number of excerpts related
to EM13CNT106, which is the relationship between science and technology involving
generation, transport, distribution and consumption of electricity, considering local
characteristics and socio-environmental conditions. Thus, a didactic sequence based
on CTSA, even without having been developed to achieve these skills, as long as it is
well planned, is capable of expressing competences and abilities in students without
running away from the classroom content.A pesquisa aqui apresentada teve por objetivo a análise das habilidades
manifestadas por alunos do primeiro e segundo ano do Ensino Médio quando
submetidos a uma Sequência Didática (SD) em forma de intervenção pedagógica
baseada na relação Ciência-Tecnologia-Sociedade-Ambiente (CTSA) sobre a
temática “Fontes de Energia”. Baseados na perspectiva dos referenciais de
abordagem CTSA, foi produzida uma intervenção pedagógica sobre o tema e
desenvolvida com um total de 42 alunos de uma escola de ensino médio e técnico.
Após o desenvolvimento da SD, as produções e falas dos estudantes foram
analisadas com base nas competências e habilidades disponíveis nos documento
curricular oficial de Ciências da Natureza e suas Tecnologias do Ensino Médio, a
Base Nacional Comum Curricular (BNCC). Os resultados demonstram que todos os
registros expressaram, pelo menos, uma habilidade, algumas muito coerentes com a
temática proposta, outras mais gerais, porém, todas com relação CTSA. Foram
manifestadas habilidades principalmente relacionadas ao tema Fontes de Energia, e
é possível relacionar as habilidades manifestadas através de abordagem CTSA da
SD. A habilidade que apresentou o maior número de excertos relacionados foi a
EM13CNT106, que estabelece relação entre a ciência e a tecnologia envolvendo
geração, transporte, distribuição e consumo de energia elétrica, considerando as
características locais e as implicações socioambientais. Dessa forma, uma
sequência didática elaborada baseada a partir de CTSA, mesmo sem ter sido
desenvolvida para atingir essas habilidades, desde que bem planejada, é capaz de
expressar competências e habilidades nos alunos sem fugir do conteúdo da sala de
aula
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
