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
Cobertura mediada da violência urbana: análise do app colaborativo “Onde Tem Tiroteio” e fornecimento de conteúdo para telejornais no Brasil
No full textAs práticas profissionais dos jornalistas e as dinâmicas das redações vêm sendo alteradas por ferramentas tecnológicas e aplicativos amplamente utilizados na produção de notícias. Uma das principais mudanças é o distanciamento dos repórteres das ruas, algo agravado, em determinados territórios do Brasil, pelos casos de ameaças e agressões a esses profissionais. Baseado nesse contexto, neste artigo, procura-se analisar o app “Onde Tem Tiroteio” (OTT), organizado por cidadãos sem o auxílio de jornalistas, e o fornecimento de informações e imagens da violência urbana para telejornais. Levantamos a hipótese de que o app funcione como ferramenta mediadora para a cobertura jornalística, deixando de ser uma mera fonte para alcançar status jornalístico. Em termos metodológicos, utilizamos a combinação da observação direta inspirada na etnografia virtual com entrevistas em profundidade com jornalistas das quatro principais estações televisivas no país. Os resultados sugerem que o app realiza um trabalho de apuração que conta com a confiança dos jornalistas, o que ajuda a acelarar a elaboração das notícias
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
APPS colaborativos e autoridade Jornalística: o OTT e o fluxo distributivo de flagrantes da violência urbana no Brasil
No full textO jornalismo como um todo tem sido desafiado pelo aperfeicoamento da tecnologia e
pela atuação do público na produção de informações altamente relevantes. De um lado,
o melhoramento da volocidade de conexão à internet, o aperfeiçoamento dos
dispositivos móveis e a criação de aplicativos inteligentes, entre outros fatores,
convocam o jornalismo à adaptação, transformando as rotinas laborais e produtivas de
maneira surpreendente. De outro lado, ainda que sem uma formação técnica
consistente, para o bem e para o mal, os cidadãos parecem compromissados com a
tarefa de registrar e propagar informações e imagens de um cotidiano por vezes
inalcançavel ao jornalismo tradicional. No telejornalismo, essa realidade é evidenciada
através do uso contínuo de flagrantes captados por cidadãos não-jornalistas.
Neste contexto, o tema violência urbana ocupa lugar central, pois, em países como o
Brasil, o trabalho jornalístico tornou-se complexo e difícil de ser realizado ao longo das
últimas duas décadas devido a ameaças e assassinatos durante coberturas. A
preocupação com a segurança dos repórteres e cinegrafistas afastou os profissionais de
regiões conflagradas, abrindo espaço para o surgimento de iniciativas e sistemas
comunicacionais descentralizados, organizados e geridos por cidadãos. O aplicativo
Onde Tem Tiroteio (OTT) pode ser interpretado como um exemplo deste fenômeno
sendo, por isso, objetivo empírico ilustrativo desta tese.
Com milhões de usuários que regulam o app e promovem uma espécie de verificação
coletiva de ocorrências ligadas à criminalidade, e com um intenso fluxo de flagrantes de
violência urbana, o OTT conquistou o lugar de ferramenta mediadora credível entre os
jornalistas e as zonas de conflito armado. Mas seu status jornalístico está ligado à
capacidade de apuração e ao fornecimento de conteúdo imagético confiável, o que torna
o app mais do que uma mera fonte para os noticiários. O principal objetivo deste
trabalho é discutir os conflitos de autoridade decorrentes de tal conjuntura.Journalism as a whole has been challenged by the improvement of technology and the
role of the public in producing highly relevant information. On the one hand, the
improvement in internet connection speed, the improvement of mobile devices and the
creation of intelligent applications, among other factors, call journalism to adaptation,
transforming work and production routines in a surprising way. On the other hand,
even without consistent technical training, for better or for worse, citizens seem
committed to the task of recording and disseminating information and images of
everyday life that are sometimes unattainable by traditional journalism. In
telejournalism, this reality is evidenced through the continuous use of flagrant captured
by non-journalist citizens.
In this context, the theme of urban violence occupies a central place, since, in countries
like Brazil, journalistic work has become complex and difficult to carry out over the last
two decades due to threats and murders during coverage. The concern with the safety
of reporters and cameramen kept professionals away from troubled regions, opening
space for the emergence of initiatives and decentralized communication systems,
organized and managed by citizens. The Onde Tem Tiroteio (OTT) application can be
interpreted as an example of this phenomenon and, therefore, is the empirical objective
of this thesis.
With millions of users who regulate the app and promote a kind of collective
verification of occurrences related to crime, and with an intense flow of flagrant urban
violence, OTT has conquered the place of a credible mediating tool between journalists
and armed conflict zones. But its journalistic status is linked to its ability to verify and
provide reliable imagery content, which makes the app more than a mere source for
news. The main objective of this work is to discuss the conflicts of authority resulting
from such situation
