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
Clinical symptoms, paraclinical tests and histopathological results in children with acute appendicitis in Zabol southeast of Iran: a cross-sectional study
Get PDFBackground: This article aimed to assessment clinical signs and symptoms, paraclinical tests and histopathological results in children with acute appendicitis.Methods: A cross-sectional study conducted on 100 children with acute appendicitis in an urban hospital in southeast of Iran from January to December 2016. Participants were selected by simple random sampling method. Clinical signs and symptoms, paraclinical tests and histopathological results recorded in checklists. The data were analyzed using SPSS 22.Results: Mean age of the patients was 10.26±3.25, fourthly-eight of patients (58.5%) were males and 34 patients (41.5%) were females. The most frequent clinical signs and symptoms were acute suppurative appendicitis with peri appendicitis (45.83%) and acute suppurative appendicitis (39.58%). The most frequent results in ultrasound reports were Intestinal loop thickness greater than 6 mm without peristalsis (positive report) (46.34%) and Invisible appendix (nega Hesaraki tive report) (13.41%).Conclusions: The results of this study showed that abdominal pain and RLQ tenderness were the most common signs and symptoms and WBC left-shift was the most common laboratory finding. Since the rate of negative appendectomy in this study was consistent with surgical results and other articles, it is concluded that diagnostic accuracy of preoperative appendectomy was acceptable and most children with acute appendicitis underwent appendectomy.</jats:p
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
Effect of probiotic supplement (kidilact) on prevention of acute diarrhea in children: a double-blind randomized clinical trial
Get PDFBackground: Acute viral diarrhea is one of the most common diseases in children, which is associated with high risk of mortality. The present study aimed to determine the effect of Kidilact on the treatment of children with acute diarrhea.Methods: This double-blind randomized clinical trial was conducted on 84 children aged 6-60 months with diarrhea, hospitalized in pediatric ward of Amir al-Mu'minin hospital of Zabol, Iran. The patients who met the inclusion criteria were included and assigned to the control and treatment groups (42 patients in each group). Data collection instruments included clinical examination of participants in terms of gender, medication, diet, stool test, weight, average heart rate, average respiratory rate, average body temperature, and average frequency of defecation Data was analyzed with descriptive and analytical tests (chi-square, Fisher's exact test, t-test, etc.) in SPSS-21.Results: Body temperature, heart rate, and frequency of defecation significantly reduced in the intervention group after three days (p<0.05). In addition, weight gain presented an improving trend in the intervention group, but not significantly different from the control group (p<0.05).Conclusions: Findings indicated that the use of Kidilact may be helpful in the treatment of acute viral diarrhea in children and play a key role in early recovery, reduction of disease severity, and improvement of vital signs in these patients.</jats:p
A comparison of serum and transcutaneous methods for diagnosis of neonatal hyperbilirubinemia
Get PDFBackground: Bili-Check is a simple test for non-invasive, quick, and painless estimation of the total serum bilirubin. This research aimed to compare serum and transcutaneous methods for the diagnosis of neonatal hyperbilirubinemia.Methods: In this descriptive study, a sample of 120 neonates diagnosed with hyperbilirubinemia was selected using convenience non-probability. They were hospitalized in Amir Al-Momemin Hospital of Zabol, Iran in 2013. The extent of neonatal bilirubin was measured by NINGBO DAVID and lab test. Then, they were compared. The data were analyzed using correlation and t-test in SPSS 22.Results: In this descriptive study, a sample of 120 neonates diagnosed with hyperbilirubinemia was selected using convenience non-probability. They were hospitalized in Amir Al-Momemin Hospital of Zabol, Iran in 2013. The extent of neonatal bilirubin was measured by NINGBO DAVID and lab test. Then, they were compared. The data were analysed using correlation and t-test in SPSS 22.Conclusions: The results showed that Bili-Check can be recommended as an appropriate tool for screening and monitoring phototherapy process. The serum method can be replaced by Bili-check.</jats:p
A Study on UTI Prevalence of Neonates Younger than 8 Weeks Diagnosed with Prolonged Neonatal Jaundice
No full textDispelling 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
