Personal perception quality of life in 68 patients with traumatic thoraco-lumbar vertebral fractures treated with circumferential arthrodesis [Valutazione soggettiva della qualità di vita in 68 pazienti trattati per fratture vertebrali traumatiche toraco-lombari con artrodesi circonferenziale]
No full textAim. In the last decade techniques in vertebral surgery have made great progress, especially in the treatment of spinal fractures. The aim of this study was to evaluate the efficacy of circumferential arthrodesis surgical technique of vertebral stabilization in accordance with the patient's point of view in terms of personal perception of one's own health condition and quality of life. Methods. The SF-36 Health Survey and the Oswestry low back pain disability questionnaire were supplied to 68 patients with spinal fracture, with or without neurological impairment, followed during a 5.5-year mean period after surgical treatment. A case-control comparative study was developed between the SF-36 health survey patient's scores and the mean SF-36 scores of a representative sample of 2000 Italian people provided together with the SF-36 questionnaire. Results. SF-36 scores in patients with neurological impairment were significantly inferior to those of the representative sample, while not neurological impaired patient's scores were not significantly different from those of the representative sample in no one of each different health concepts explored by the shortform scales. The low back pain concerned disability was severe to crippled in neurological impaired patients, and minimal to moderate in patients without neurological impairment. Conclusion. The surgical technique of vertebral stabilization with circumferential arthrodesis succeeds in bringing patients with not neurological spinal injuries back to a quality of life not significantly different from that of general sound population. Patients with neurological spinal injuries get a quality of life significantly inferior due to irreversibility of neurological damage
The Judet quadricepsplasty for the management of post-traumatic stiffness of the knee. A retrospective analysis of 21 cases [L'artromiolisi secondo Judet nel trattamento delle rigidità post-traumatiche di ginocchio. Analisi retrospettiva di 21 casi]
No full textAim. After 50 years, the Judet quadricepsplasty is still the main therapy for stiffness of the knee. This surgery consists of cutting the proximal insertion of the vastum lateralis muscle, releasing all the connections that the quadriceps has with the femour and releasing the intra-articular adhesions. A retrospective analysis of the stiffness of the knee treated since 1985 with the Judet quadricepsplasty was performed at the 1st Department of Orthopedics, University of Turin. The aim was to determine if the operative risks, the long scar, the hard physiotherapy and the possible complications were justified by the quality of the results. Methods. Twenty-one Judet quadricepsplasties with a 2-year minimum follow-up were reviewed. Surgery has been performed for severe extension contractures due to femur fractures. Results. Preoperatively, all cases showed a severe extension stiffness with an average of 25° flexion. The average improvement in knee flexion at follow-up was 70° with 17 (81%) patients achieving a final flexion of 80° or more. The results of 2 schedules, WOMAC and SF 36, have shown how their quality of life is very close to the general population. Conclusion. These results show how Judet quadricepsplasty can still be considered an up-to-date method due to its versatility and low rate of complications

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
