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
TESTICULAR TORSION: CAUSATIVE FACTOR IN DELAYED MANAGEMENT
No full textObjective: Analyzing the factors causing delays in the management of patients with testicular torsion in Dr. Cipto Mangunkusumo General Hospital Jakarta. Material & methods: This research is a retrospective research using questionnaire from patients as primary data and from Dr. Cipto Mangunkusumo General Hospital medical records or urologic reports as secondary data from 1st January 2011 to 30th April 2015. Results: 4 patients diagnosed with left testicular torsion admitted to hospital with >4 hours onset (as a prehospital factor). 3 of 4 patients were adult, who came with left testicle pain. The minimum VAS score perceived is 2. 3 of 4 patients had 540o medial left testicle rotation intraoperatively while all patients left testicles were unvital. Conclusion: Further examination is required to diagnose testicular torsion in adult-geriatric. Non-specific complaints, such as lower abdominal pain or painful testicles and mild pain in scrotum were some of the most important factors, thus causing delays in testicular torsion management. However, a comprehensive education to all health workers, especially for doctors is still required, because the complaints of pain in patients with testicular torsion does not always appear acutely. This becomes important for early identification of patients with testicular torsion, in order to prevent delay in management
RISK FACTORS FOR URETHROCUTANEOUS FISTULAS FORMATION AFTER ONE STAGE HYPOSPADIAS REPAIR
Full text linkObjective: To evaluate risk factors that contribute to urethrocutaneous fistulas formation after one stage hypospadias repair. Material & method: A case control study was performed on hypospadias patients that underwent one stage hypospadias repair. We analyzed the correlation of urethrocutaneous fistula formation with patient age, hypospadias classification, chordee severity, other urogenital anomalies, history of hormonal therapy, suture size, duration of operation, type of dressing, type of stent, duration of stenting, and three types of operation technique, which are TIP, Duckett, and Onlay Island Flap. Results: There were 116 patients with mean age 5,7 ± 3,9 years old (4 months – 19 years old). Urethrocutaneous fistula occured in 12 patients (10,3%). From the data analysis, we didn’t find any significant correlation between urethrocutaneous fistula formation and patient’s age (p = 0,426), hypospadias classification (p = 0,695), chordee severity (p = 0,564), other urogenital anomalies (p = 0,964), history of hormonal therapy (p = 0,739), suture size (p = 0,248), duration of operation (p = 0,856), type of dressings (p = 0,580), type of stents (p = 0,600), and duration of stenting (p = 0,796). We also didn’t find any significant correlation between urethrocutaneous fistula formation and operation technique TIP vs Duckett (p = 0,314), and TIP vs Onlay Island Flap (p = 0,644). Conclusion: There were no significant correlation between urethrocutaneous fistula formation and patient age, hypospadias classification, chordee severity, other urogenital anomalies, history of hormonal therapy, suture size, duration of operation, type of dressing, type of stent, and duration of stenting. There were also no significant correlation between urethrocutaneous fistula formation and operation technique TIP vs Duckett, and TIP vs Onlay Island Flap.

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
RELATION BETWEEN COMPLICATING FACTORS OF HYPOSPADIA AND COMPLICATIONS AFTER TIP: A RETROSPECTIVE STUDY
No full textObjective: This study aims to find an association between hypospadias complicating factor for complications that occurred after hypospadias reconstruction, focusing on tubularized incised plate (TIP) as reconstruction techniques are most commonly used. Material & methods: The study data was obtained from medical records of urologic hypospadias patients in Cipto Mangunkusumo General Hospital, Jakarta. Samples are those who underwent hypospadias reconstruction in Cipto Mangunkusumo General Hospital, since April 2002 until May 2014 with a total sampling method. Data were analyzed using SPSS ver 14. Results: We collected 127 patients who underwent the TIP technique with a mean patient age and treatment duration was 7.58 years and 10.95 days. Fistule is the most common complication in patients with post-TIP hypospadias accounting for as high as 32 (25.2%). Bivariate analysis showed a significant correlation between the location of the hypospadias meatus (distal) with torsion of the penis (n = 2; p 0.019). Conclusion: On the basis of the technical complications TIP, such as fistules, meatus stenosis, urethral stricture, torsion of the penis, and glans dehiscence, then the indication for TIP should be clear or selective
