Pandemic: From science and common sense to scientificsm
Get PDFThe Ebola virus (EBOV) was named after the Ebola River in the Democratic Republic of Congo (DRC) (previously Zaire). All afflicted nations reported a total of 27,741 EVD cases and 11,284 deaths as of July 22, 2015. Prior to the 2013-2016 EBOV epidemic, the number of confirmed human cases in EBOV outbreaks was very low, with no more than 425 cases each outbreak between 1976 and 2009, compared to an estimated 28,646 cases between 2013 and 2016. Monkey pox was initially found in 1958, when two outbreaks of a pox-like disease occurred in research colonies of monkeys, hence the name. SARS is predominantly a respiratory disease, with the maximum concentration of SARS-CoV found in the respiratory tract, though this virus is also identifiable in other organs and tissues, as well as in stool. COVID-19 affected almost all countries altogether and numerous innovative and developing technologies are mandatory to tackle various complications caused by the extent of the epidemic in the health organizations.Fil: Ferder, León.

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
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
Vitamin D deficiency in African Americans is associated with a high risk of severe disease and mortality by SARS-CoV-2
Get PDFCOVID-19 is said to be a pandemic that does not distinguish skin color or ethnic origin, but data in many parts of the world, especially in the United States, begins to show that there is a sector of society that is suffering a more significant impact from this pandemic. The black population is being more vulnerable than the white population to infection and death by COVID-19, and hypertension and diabetes mellitus seems to predispose to this vulnerability. Over time, multiple disparities have been observed between the health of blacks and whites, mainly associated with inequalities in the socio-economic scope. However, little by little, some mechanisms and pathophysiological susceptibilities that are directly related to the higher prevalence of multiple diseases in the black population, including infection and death by COVID-19, begin to be elucidated.Plasma vitamin D levels and evolutionary adaptations of the renin-angiotensin-aldosterone system in black people are considerably different between this and other races, and it is well established their role in the development and progression of hypertension and multiple lung diseases, among them, COVID-19 infection.This letter to discuss and proposes whether or not vitamin D and renin-angiotensin-aldosterone system ethnical disparities influence susceptibility to infection and death by COVID-19 in black people and suggests possible mechanisms for this susceptibility.Fil: Martín Giménez, Virna Margarita.
