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
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
Development and validation of a test for the assessment of knowledge learned by healthcare students during an online course on COVID-19: cross-sectional study
No full textMany Italian universities during the COVID-19 pandemic had numerous students attending hospital wards. The training of health care students was necessary to prepare for good practices in implementing knowledge about COVID-19 and minimizing contagion among students who carried out the internship. In February 2020, a course aiming to guide health personnel so that they can appropriately address the health emergency posed by the new coronavirus was created, making use of the scientific evidence currently available as well as official sources of information and updates. The aim of this study was the development and validation of a useful tool to evaluate the progress in knowledge regarding COVID-19 of students in degree courses for the health care professions. The reliability of the test was assessed using Cronbach's alpha (α) coefficient, while the responsiveness of the test between T0 and T1 was measured with a student t test. The standard error of measurement was used to calculate the minimal detectable change of the tool. The test is made up of 31 items with four multiple-choice answers, one of which is correct. Fifteen bachelor's degree courses at the Sapienza University of Rome were enrolled, for a total population of 1,017 students from different course years. The test showed good internal consistency, with Cronbach's α values of 0.82. The item-total analysis also showed good results, with homogeneous α values from 0.80 to 0.82 for each item. The student t test showed a difference of 3.59 between T0 and T1 (p < 0.001). The minimal detectable change was 0.47. The test is a useful tool for assessing progress in skills regarding COVID-19 for students from bachelor's degree courses in the health professions. It allows the improvement and acquisition of skills as well as a qualitative analysis of the organization of internship degree courses
XI Seminar - PhD Day COVID-19: Facing a multi(face)phase pandemic Virtual Meeting Organized by the Italian National Institute of Health and Sapienza University of Rome September 17 and 24, October 1 and 8, 2020
No full textThe 11th Seminar of PhD students in Infectious Diseases, Microbiology and Health Sciences has
been delayed and will be carried out online due to the recent COVID-19 pandemic. Indeed, this
tragical event, that has dramatically affected people’s life all over the world, will be the core of the
topics considered. The Seminar is scheduled in four days, each characterized by an in-depth analysis
of topics related to the pandemic, such as the establishment of predictive models, the clinical,
diagnostic and anatomopathological aspects, the effects of social distancing and the impact of the
pandemic on the socially less-favoured people.

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
