No full textObjectives. The aim of this study was to define the most effective protocol for temporomandibular joint arthrocentesis through comparative efficacy analysis of three different treatment protocols involving joint lavage with or without the use of drugs to manage symptoms of intracapsular disorders. Materials and methods. The study sample consisted of 31 consecutively enrolled patients with unilateral intracapsular pathology and pain lasting more than 6 months. Criteria for inclusion in the study were the presence of functional limitation and pain that were refractory to conservative treatments and a diagnosis of osteoarthritis based on the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD, Axis I, Group IIIb). The study design provided a single arthrocentesis procedure associated with single-needle joint lavage using normal saline, low molecular weight hyaluronic acid, or corticosteroids. Results. Marked improvements were reported for all variables, regardless of the drug injected. Hyaluronic acid produced slightly better outcomes, but the differences with respect to steroids were not statistically significant, except the one regarding improved masticatory efficiency (p = 0.043). Conclusions. Single-needle viscosupplementation with hyaluronic acid was only slightly more effective that joint lavage with corticosteroids or with normal saline alone. Further investigation is needed to obtain deeper insight into the clinical significance of these findings. © 2011 Elsevier Srl

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
