Higth condylectomy and disc repositioning compared to arthroscopic lysis, lavage and capsular stretch for the treatment of chronic closed lock of the temporomandibular joint
No full textObjective. The article shows the 1-yr results comparing the efficacy of open-surgery high condylectomy and disc
repositioning and the arthroscopic procedure of lysis, lavage and capsular stretch in patients with chronic closed lock
of the temporomandibular joint (TMJ).
Study design. Twenty patients with a clinical and radiologic diagnosis of chronic closed lock were randomly chosen
to be treated with either open surgery or arthroscopy. Each patient was evaluated with a visual analog scale (VAS) for
pain and a mandibular functional impairment questionnaire (MFIQ). The evaluation also included a clinical
examination. Each patient was recorded at baseline before surgery and at 1-yr follow-up. Statistical analysis was made
to evaluate whether differences in MFIQ, VAS, maximum opening and protrusion, lateral joint tenderness, muscle
tenderness, crepitation, and clicking at 1-yr follow-up from baseline were significant. Results were considered
statistically significant when P _ .05.
Results. Both open surgery and arthroscopic surgery reduced pain and improved mandibular function. The severity of
pain was significantly reduced in both groups (P _ .005). In both the open and arthroscopy groups mandibular
function improved significantly (P _ .005). The clinical examination showed similar good results for the 2 surgical
procedures. At 1-yr follow-up a majority of patients from both the open (80% of the patients) and the arthroscopy
(70% of the patients) groups fulfilled the criterion of a cutoff point for maximum interincisal opening of equal or more
than 35 mm (P _ 0.005); all the patients in both groups fulfilled the criterion of the cutoff point for maximum
protrusion of more than 5 mm (P _ .007). At 1-yr follow-up, clicking was the same as before surgical procedures; no
patient in the open group showed crepitation, but crepitation was found in patients in the arthroscopy group. Joint
tenderness and pain on lateral palpation as well as muscle tenderness and pain were reduced in all the cases,
disappearing in some of them, but the difference was significant only regarding joint tenderness (open surgery, P _
.016; arthroscopy, P _ .031).
Conclusions. Open-surgery high condylectomy and disc repositioning and the arthroscopic procedure of lysis, lavage
and capsular stretch are both effective surgical methods to treat symptomatic patients with a diagnosis of chronic
closed lock of the TMJ. Because of the minimally invasive characte
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
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
