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
RELATIONSHIP BETWEEN HYPERTENSION AND COVID-19 DEATHS, CASE CONTROL STUDY
Full text linkOne of the most comorbidities to Covid-19 patient in Indonesia is hypertension, which is 52,1% in confirmed cases and 19,2% in mortality cases and be ranked first of comorbidities in Covid-19 patient. This study was aimed to determine association hypertension to Covid-19 patient death for April 2020 – July 2021 based on medical record data of inpatient at RSUD Arifin Achmad – Riau Province. Methods This is a case control study, which is cases were the death patient and controls were non-dead patient based on medical record data through SIMRS app. This study analyze 93 cases and 200 controls include in inclusion criteria which has been tested PCR. The data was analyzes use chi-square test and logistic regression. Result Based on the result, that was found association between hypertension to mortality of covid-19 but have protective risk to patient in adjusted OR = 0,0661 (95% CI = 0,026 – 0,171, p value <0,0001) after controlled by age, sex, diabetes, COPD, CVD and domicile. This study result have limitation yet that is misclassification non differential and available data in medical record patient through SIMRS app so it didn’t have any strong association. A low association was found between hypertension to mortality of Covid-19 with OR adjusted = 0,0661 (95% CI = 0,026 – 0,171, p value = <0,0001) in inpatient at RSUD Arifin Achmad Province of Riau after controlled by age, sex, diabetes, COPD, CVD and domicile
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
Exclusive Breastfeeding and Decrease of Upper respiratory Infection Incidence among Infants Aged 6-12 Months in Kampar District, Riau Province
Full text linkUpper Respiratory Infection (URI) is a major cause of morbidity and mortality of infants and toddlers in developing countries. The high infant morbidity and mortality rates in Indonesia are associated with the low exclusive breastfeeding ability. Breast milk is a natural drink for newborns in the first month of life that is beneficial not only for the babies, but also for mothers. The aim of study was to determine exclusive breastfeeding and decrease in incidence of URI among infants aged 6-12 months. This study was conducted by using case control design. Samples were taken by using cluster random sampling. Subject of study consisted of 162 cases and 162 control with infants aged 6-12 years. Cases were 162 infants aged 6-12 months suffering from URI within one last month and taken by mothers to primary health care that was selected location of study, while control was mothers who took their infants aged 6-12 months who did not suffer from URI within one last month to the selected primary health care. Data analysis included univariate, bivariate, stratification, and multivariate analysis with logistic regression. Results of study found that infants who were not exclusively breastfed were 1.69 times (95% CI: 1.02-2.80) more at risk of increasing URI incidence compared to infants who were breastfed exclusively after controlled by smoker in house and immunization variables. Health promotion of 6-month exclusive breastfeeding, provision of immunization, and anti-smoking program need to be implemented continuously to decrease the rates of morbidity and mortality due to URI disease
