Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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

Previous issue date: 2019Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Objective: To evaluate the effects of compliance during periodontal maintenance therapy (PMT) in the oral impact on daily performance (OIDP) measures, as well as to determine and compare the periodontal condition of acceptable and irregular compliers. Material and methods: From a 6-year prospective cohort study with 268 individuals under PMT, 232 individuals had complete periodontal clinical data and OIDP questionnaires completed between T1 (data was recorded after the first PMT appointment) and T2 (final data at the last PMT appointment), were determined to be eligible. Individuals were divided into two groups: 124 acceptable compliers (AC) and 108 irregular compliers (IC). Full-mouth periodontal examination and questionnaires were evaluated in 2 times, at T1 and T2. Results: At T2, the periodontal status of the AC group was significantly better than the IC group. The IC group also presented with higher OIDP scores (63.31 +/- 19.11) compared to the AC group (57.72 +/- 15.30, p = 0.005). On analyzing the OIDP dimensions independently, both groups (AC and IC) presented with high scores in the functional, psychological and social performances; however, the impacts were significantly higher in IC group. Conclusion: The AC group presented with better periodontal conditions and lower OIDP, compared to the IC group. The discomfort and dissatisfaction with appearance, showed more influence on these daily impacts. Clinical significance: Acceptable compliers showed lower scores of OIDP when compared to erratic ones. Thus, clinicians could take the chance to gain advantage from the positive impacts of acceptable compliance in the OHRQL for subsequent patient-centred motivation during PMT.[Costa, Fernando Oliveira; Costa, Amanda Almeida; Cyrino, Renata Magalhaes; Miranda Cota, Luis Otavio] Univ Fed Minas Gerais, Sch Dent, Dept Periodontol, Belo Horizonte, MG, Brazil[Cortelli, Sheila Cavalca; Costa, Amanda Almeida; Cortelli, Jose Roberto] Universidade de Taubaté (Unitau), Dept Dent, Periodont Res Di
Variations on the Author
Full text link“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
Full text linkWe 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
Full text linkWe 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

Previous issue date: 2017Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)The objective of this study was to compare the effect of one-stage full-mouth disinfection (FMD) and conventional quadrant scaling in four weekly sessions (QS) on periodontal clinical parameters and halitosis among individuals with advanced chronic periodontitis. In this randomized controlled clinical trial, 30 individuals were divided into two groups: FMD (n = 15) and QS (n = 15). The following data were collected at the baseline and 90 days after treatment: plaque index, tongue-coating index (TCI), bleeding on probing, probing depth, and clinical attachment level. Halimetry was performed by the organoleptic method, and the levels of volatile sulfur compounds (H2S and CH3SH) were measured by gas chromatography. The Chi-square, Fisher's exact, the Mann-Whitney, the McNemar, and the Wilcoxon tests were used for statistical analysis. Both groups showed statistically significant improvements in periodontal clinical parameters, reduction in TCI, organoleptic scores, and in CH3SH levels between times. However, major reduction was observed in FMD group. Non-surgical periodontal therapy, regardless of the protocol, was effective in improving periodontal clinical status of individuals, decreasing organoleptic scores and CH3SH levels between times, as well as reducing halitosis. This study contributed to the knowledge that non-surgical periodontal therapy, whether by FMD or QS, was effective in reducing halitosis in individuals with advanced chronic periodontitis.[Silveira, Juliana Oliveira; Costa, Fernando Oliveira; Dutra, Bernardo Carvalho; Miranda Cota, Luis Otavio] Univ Fed Minas Gerais, Dept Dent Clin Oral Pathol & Oral Surg, Belo Horizonte, MG, Brazil[Dutra Oliveira, Peterson Antonio; Soares Dutra Oliveira, Alcione Maria] Pontificia Univ Catolica Minas Gerais, Dept Periodontol, Belo Horizonte, MG, Brazil[Cortelli, Sheila Cavalca; Cortelli, Jose Roberto] Universidade de Taubaté (Unitau), Periodont Res Div, Dept Dent, Sao Paulo, Brazil[Costa, Fernando Oliveira] Univ Fed Minas Gerais, Sch Dent, Dept Periodontol, Antonio Carlos Ave 6627,POB 359, BR-31270901 Belo Horizonte, MG, Brazi
