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
Organization, Clinical and Management Indicators on the First Year of Activity of an Outpatient Clinic Dedicated to the Diagnosis and Treatment of Severe Asthma in Italy
No full textPurpose: A Regional Technical Commission was set in 2017 by Veneto region (Italy) to provide opinions and recommendations on drug prescriptions and to implement treatment-pathway guidelines for severe asthma. In this observational study, we describe the first structured, integrated, multidisciplinary, patient-centered outpatient clinic for the care of severe-asthma patients in Italy, and characterize patients referring to the center for specialist visits.Patients and Methods: To characterize patients that accessed the outpatient clinic in 2018, data on demographic characteristics, treatments, severity of asthma, phenotypes, and relevant comorbidities by phenotype were collected. Use of biologic agents and indicators of the performance of the outpatient clinic were described.Results: A structured multidisciplinary outpatient pathway for taking charge of patients and for administration and monitoring of biological agents was developed. A total of 146 patients accessed the outpatient clinic in 2018: 62.3% had uncontrolled asthma upon admission and 27.4% were already being treated with biologic agents. Among patients with uncontrolled asthma, 66% had severe uncontrolled asthma, 22% had moderate-severe uncontrolled asthma, and 12% had mild-moderate uncontrolled asthma. Main asthma phenotypes in uncontrolled-asthma patients were allergic (58% of patients), eosinophilic (22%), allergic plus eosinophilic (10%) and non-atopic asthma (10%). Among patients affected by severe asthma, 47% had allergic asthma, 28% had eosinophilic asthma, 13% had allergic plus eosinophilic asthma, and 12% had non-atopic asthma. Nasal polyps were more frequent in eosinophilic and allergic plus eosinophilic asthma, while gastro-esophageal reflux disease was more frequent in non-atopic asthma.Conclusion: This structure of an outpatient clinic for the treatment of severe asthma, with its dedicated pathway and multidisciplinary approach, may allow a stricter control of asthma and optimization of therapies, as well as minimization of drug misuse
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
Palivizumab nella profilassi del virus respiratorio sinciziale: analisi di impatto sul budget del SSN italiano
Full text linkPalivizumab is a monoclonal antibody to RSV that has been shown to significantly reduce the frequency of hospitalisations for RSV infection, in at-risk populations. However, payers are concerned about the budgetary impact of adopting palivizumab. A budget impact model was developed to estimate the financial impact of palivizumab for the prevention of severe RSV infection in at-risk populations in the Netherlands. These analyses were adapted to Italy, after a brief review of the literature on the health care system and epidemiology of RSV infection in our country. The report below outlines the methodology and analysis of the costs associated with palivizumab prophylaxis of premature infants of 33 to 35 weeks gestational age which are the at-risk subgroup eligible for prophylaxis according to Italian guidelines
