Imaging the scaphoid problem : a diagnostic strategy for suspected scaphoid fractures
Get PDFIn this thesis, the diagnostic value of bone scintigraphy in daily practice has been assessed. In addition, the results of bone scintigraphy have been compared with clinical outcome and the observer variation of bone scintigraphy has been established. Furthermore, the role of acute MR imaging in suspected scaphoid fractures and the observer variation of MR imaging have been determined. Finally, the function of the wrist and strength measurements have been assessed for their use in the diagnostic strategy of suspected scaphoid fractures The following conclusions have been established. Firstly, suspected scaphoid fractures are common and mandate further investigation. Secondly, function of the wrist and strength measurements improve the diagnostic strategy of suspected scaphoid fractures. Thirdly, MR imaging fails to identify up to 20% of scaphoid fractures. Fourthly, the observer variation of bone scintigraphy is less than the observer variation of MR imaging. Finally, bone scintigraphy in combination with clinical follow-up is the standard for suspected scaphoid fractures to date.Biomet Nederland BV DePuY a Johnson & Johnson company Endocare BV J.E.

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
The non-displaced scaphoid fracture : evaluation of diagnostic modalities & conservative treatment
Get PDF__The non-displaced scaphoid fracture: evaluation of diagnostic modalities & conservative treatment__ Over de diagnostiek en de behandeling van scafo_dfracturen bestaat nog veel verschil van mening. Een onjuiste of vertraagd ingestelde behandeling kan leiden tot ernstige complicaties. R_ntgenfoto mist een groot deel van de scafo_dfracturen. De botscintigrafie kan gebruikt worden om deze fracturen zichtbaar te maken. Een botscintigrafie is echter invasief en maakt gebruik van radioactief materiaal. Een MRI of CT zou wellicht de botscintigrafie kunnen vervangen. Dit proefschrift beschrijft twee prospectieve studies, waarbij in de eerste studie de botscintigrafie werd vergeleken met de MRI. In de tweede studie werd de botscintigrafie vergeleken met de CT. Beide onderzoeken konden niet aantonen dat de MRI en CT de botscintigrafie kan vervangen. Het probleem is dat beide onderzoeken scafo_dfracturen missen. Ook is onderzocht of een zogenaamde 'clinical prediction rule' te ontwikkelen was, om de a priori kans op een ware fractuur bij een pati_nt met de verdenking op een scafo_dfractuur te verhogen. Analyse liet zien dat er drie voorspellers significant waren: extensie < 50%, supinatiekracht < 10% en het hebben van een fractuur in de voorgeschiedenis. Tenslotte is de behandeling van scafo_dfracturen geanalyseerd. Gekeken is of een kortere behandeling mogelijk was. Normaal wordt een scafo_dfractuur 12 weken ge_mmobiliseerd met een gips. Lange immobilisatie kan klachten veroorzaken. Wij hebben onderzocht of de scafo_dfractuur ook te behandelen is middels een gipsimmobilisatie van 6 weken. Hiervoor werden 98 pati_nten geanalyseerd en na 6 weken bleek 80% te zijn genezen. Wat ook bleek is dat de localisatie met name invloed had op de functionele uitkomst van de behandeling. Om deze functionele uitkomst in beeld te brengen gebruikten we een DASH-score (Disabilities of the Arm, Shoulder and Hand score). De gemiddelde DASH-score was 6 voor 13 distale pool en 5 voor 44 middenpool fracturen. Concluderend kunnen wij stellen dat voor het opsporen van scafo_dfracturen bij pati_nten met een klinische verdenking hierop, de botscintigrafie nog steeds de gouden standaard is. Niet gedisloceerde scafo_dfracturen van de distale middenpool dienen conservatief behandeld te worden middels gipsimmobilisatie gedurende 6 weken.Traumacentrum West Nederlandse Vereniging voor Traumatologie Raad van Bestuur MCHUBL - phd migration 201
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
Dispelling 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
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
