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
Molecular epidemiology of ESβL producing P. mirabilis strains from a long-term care and rehabilitation facility in Italy
No full textWe report the detection of multidrug resistant ESbetaL producing Proteus mirabilis isolates from a long-term care and rehabilitation facility (LTCRF) in Northern Italy. 53% of the collected P. mirabilis strains were ESbetaL producers. PCR and sequencing techniques confirmed the presence of the bla(TEM-92) and bla(CMY-16) resistance genes in 23/26 (88.5%) and 3/26 (11.5%) of the ESbetaL producers respectively. PFGE showed that the TEM-92 beta-lactamase producing isolates were not clonally related, indicating the presence of at least four different clonal lineages (A, B, C, D), whereas all the CMY-16 enzyme producers belonged in the same lineage. The bla(TEM-92) and bla(CYY-16) determinants were distributed in seven different wards, but in three of them they coexisted. Our results show that the most patients are co-colonized by ESbetaLs producing P. mirabilis strains at the time of admission to an LTCRF. An effective strategy to curtail the spread of ESbetaLs mediated resistance in LTCRFs could be to activate sourveillance programs to monitor routinely the entry of resistant bacteria
Long-Term Outcome of Laparoscopic Nissen Procedure in Pediatric Patients with Gastroesophageal Reflux Disease Measured Using the Modified QPSG Roma III European Society for Pediatric Gastroenterology Hepatology and Nutrition's Questionnaire.
No full textBackground/Purpose: Laparoscopic fundoplication (LF) represents the gold standard for surgical treatment for
pediatric patients with gastroesophageal reflux disease (GERD).
Methods: We report the results of long-term outcome of 36 patients who had undergone LF from January to
December 1998, with a follow-up longer than 10 years (range 11–12 years). The patients were invited, by phone,
to undergo a clinical follow-up. All patients underwent the modified European Society for Pediatric Gastroenterology
Hepatology and Nutrition (ESPGHAN)’s Roma III questionnaire; however, only 22 out of 36 patients
accepted to be controlled in a day hospital setting, and 10 out of 36 accepted to undergo a telephonic questionnaire.
Our study is focused on the data of these 32 patients.
Results: Twenty-eight out of 32 (87.5%) patients had completely recovered; 4 out of 32 patients (12.5%) had a
mild persistent GER; 9 out of 32 patients (28%) referred a mild dysphagia; 21 out of 32 (66%) patients could burp;
and only 9 out of 32 (28%) patients could vomit. The cosmetic result was good in 30 out of 32 (94%) patients. The
weight/height ratio was satisfactory in 28 out of 32 (87.5%) patients. The quality of life was good in 28 out of 32
(87.5%) patients.
Conclusions: Our experience shows that the long-term follow-up after LF produces a good clinical result and a
good quality of life. The modified ESPGHAN’s Roma III questionnaire seems an effective way to check the longterm
results, because it avoids submitting patients to long and not well tolerated instrumental exams
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
ß-LATTAMASI DI TIPO AMPC ACQUISITE IN PROTEUS MIRABILIS: UN FENOMENO IN AUMENTO NELLA PRATICA ASSISTENZIALE
No full textDispelling 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
