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
Tabagismo na gestação: um estudo de série temporal no extremo sul do Brasil
Get PDFDissertação (Mestrado)Objetivo: Medir prevalência, avaliar tendência e disparidades na ocorrência de
tabagismo entre gestantes residentes em Rio Grande, RS, entre 2007 e 2019.
Métodos: Foram incluídas neste estudos todas as gestantes residentes neste município
que tiveram filho em algum dos hospitais locais entre 01/01 e 31/12 nos anos de 2007,
2010, 2013, 2016 e 2019. As entrevistas ocorreram em até 48 horas após o parto.
Considerou-se como tabagista a gestante que fumou pelo menos um cigarro por dia
durante 30 dias em algum dos trimestres da gestação. Utilizou-se o respectivo teste quiquadrado de Pearson para comparar proporções e avaliar tendência.
Resultados: A prevalência média de tabagismo no período estudado foi 17,7%
(IC95%:17,0%-18,3%), caindo de 23,4% (IC95%:21,7%-25,0%) em 2007 para 12,4%
(IC95%:11,1%-13,9%) em 2019. Esta queda se deu em todas as categorias das variáveis
estudadas (ptend>0,001). As maiores disparidades foram observadas entre os grupos
extremos para renda (75,0% x 34,4%) e escolaridade (51,0% x 32,1%) e viver ou não com
companheiro (50,7% x 27,7%)
Conclusão: Houve queda acentuada e desigual na prevalência de tabagismo ao longo
desses 13 anos. Gestantes com maiores riscos de complicação durante a gravidez e o
parto estiveram em nítida desvantagem em relação às demais. A redução da prevalência
de tabagismo depende de priorizar intervenções entre àquelas de maior vulnerabilidade
social.Objective: To measure prevalence, evaluate trends and disparities in the occurrence of
smoking among pregnant women living in the municipality of Rio Grande, RS, in the
extreme South of Brazil, between 2007 and 2019.
Methods: All pregnant women living in this municipality who had a child in one of the
local hospitals between 01/01 and 31/12 in the years 2007, 2010, 2013, 2016 and 2019
were included in this study. The interviews took place within 48 hours after the birth.
birth. A pregnant woman was considered a smoker if she smoked at least one cigarette
per day for 30 consecutive days in any of the trimesters of pregnancy. The respective
Pearson chi-square test was used to compare proportions and evaluate trends.
Results: The average prevalence of smoking in the studied period was 17.7%
(95%CI:17.0%-18.3%), falling from 23.4 (95%CI:21.7%-25.0%) in 2007 to 12.4%
(95%CI:11.1%-13.9%) in 2019. This drop occurred in all categories of variables studied
(ptend>0.001). The greatest disparities were observed between the extreme groups for
income (75.0% x 34.4%) and education (51.0% x 32.1%) and living or not with a partner
(50.7% x 27.7 %)
Conclusion: There was a sharp and uneven drop in the prevalence of smoking over these
13 years. Pregnant women at higher risk of complications during pregnancy and
childbirth were at a clear disadvantage compared to others. Reducing the prevalence of
smoking depends on prioritizing interventions among pregnant women with greater
social vulnerability
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
Não planejamento da gravidez: um estudo de série temporal no Extremo Sul do Brasil
Get PDFDissertação (Mestrado)Objetivo: Estimar a ocorrência, verificar a tendência e identificar fatores associados ao não planejamento da gravidez entre puérperas residentes no município de Rio Grande, RS, entre 2007-2019;
População alvo: Todas as puérperas residentes em área urbana ou rural do município de Rio Grande, RS, cujo parto tenha ocorrido entre 01/01 e 31/12 de 2007, 2010, 2013, 2016 e 2019
Delineamento: Estudo transversal (censitário).
Desfecho: Não planejamento da gravidez.
Metodologia: Entrevistadoras treinadas aplicaram questionário único e padronizado a todas as puérperas provenientes das áreas urbana ou rural do município, que tiveram filho nos períodos citados. Foram investigadas características demográficas, socioeconômicas, reprodutivas, hábitos de vida e comportamento, além da assistência recebida durante a gestação e o parto.
Análise proposta: Verificação de frequências e distribuição das variáveis seguida análise bivariada utilizando-se do teste qui-quadrado de Pearson, depois regressão de Poisson com ajuste da variância robusta obedecendo ao modelo hierárquico prévio. A medida de efeito utilizada será a razão de prevalências com seu respectivo intervalo de confiança de 95% (IC95%).
Resultados esperados: Conhecer a prevalência, e identificar àquelas puérperas com maior possibilidade de não planejar a gravidez. A partir disso, criar estratégias a fim de alcançar estas mulheres a fim de prover orientação e métodos de contracepção para que a gravidez ocorra somente quando for planejada.Objective: To estimate the occurrence, verify the trend, and identify factors associated with unplanned pregnancy among puerperae living in Rio Grande (RS), Brazil, in the 2007-2019 period.
Target population: All puerperae residing in urban or rural areas in Rio Grande (RS) whose delivery occurred between 01/01 and 31/12 of 2007, 2010, 2013, 2016, and 2019.
Design: Cross-sectional study (census).
Outcome: Unplanned pregnancy.
Methods: Trained interviewers applied a single, standardized questionnaire to all puerperae from urban or rural areas of the municipality who had a child during the periods mentioned above. The authors investigated the demographic, socioeconomic, and reproductive characteristics, life habits, behavior, and care received during pregnancy and childbirth.
Proposed analysis: Verifying frequencies and distribution of variables followed by bivariate analysis using Pearson's chi-square test, then applying the Poisson regression with robust variance adjustment following the previous hierarchical model. The effect measure adopted will be the prevalence ratio with its respective 95% confidence interval (95%CI).
Expected results: Understanding the prevalence and identifying puerperae with a higher likelihood of unplanned pregnancy. Then, creating strategies to reach these women to provide guidance and contraceptive methods so that pregnancy occurs only when planned
Prevalências de não realização de citopalógico de colo de útero entre gestantes no municipio de Rio Grande - rs.
Get PDFO câncer do colo do útero é o terceiro tumor mais frequente na população feminina e a
quarta causa de morte de mulheres por câncer no Brasil. A detecção precoce desta neoplasia
através do exame de Papanicolaou representa uma estratégia recomendada pelo Ministério da
Saúde desde 1988 às mulheres de 25 a 60 anos. A cobertura do exame em nível nacional e
local tem mostrado tendência de melhora, porém a faixa etária dos principais estudos está fora
do recomendado pelo Ministério da Saúde, além do foco não ser adequado. O
acompanhamento das mulheres com exame de Papanicolaou alterado também carece de
maiores estudos. O pré-natal é um período ímpar para ampliar a cobertura desse exame,
porém é subutilizado para esse fim. O presente projeto tem como objetivo avaliar a não
realização de citopatológico de colo uterino no período gestacional dentre as gestantes com
nascimento em 2013 na cidade do Rio Grande, dentro da faixa etária recomendada, além de
verificar os fatores associados a não realização do mesmo
