A disability-oriented approach to long-term sequelae following traumatic brain injury
No full textItem does not contain fulltextEpidemiologie van beperkingen na traumatisch hersenletsel en de verbetering van de neuropsychologische diagnostiek staan centraal in dit proefschrift. Het proefschrift onderzocht de vraag naar de prevalentie van de beperkingen op lange termijn. Deze vraag is onderzocht middels intervieuws. De tweede vraag betreft de mogelijkheid tot verbetering van de post-acute neuropsychologische diagnostiek. Er worden een aantal nieuwe instrumenten geintroduceerd.Instituut voor neurologie, 19 november 1997Promotores : Mulder, T.W., Staak, C.P.F. van der185 p
From the mechanisms of obstacle avoidance towards the prevention of falls.

47901.pdf (Publisher’s version ) (Open Access)The problem of falls in the elderly has become a topic of growing scientific interest. Numerous studies on risk factors for falls and preventive strategies have been published in the past decades. The development of fall prevention interventions has usually been based on these known risk factors. Another approach would be to develop an intervention program that is mainly based on the reported circumstances of falls. Such interventions would typically include elements like obstacle course walking, because a large number of falls in the elderly are a consequence of tripping and stumbling over obstacles while walking. The first aim of this thesis was to evaluate the effectiveness of a new falls prevention exercise program for the elderly, which was called the Nijmegen falls prevention program. This exercise program was developed from the perspective of training in an exercise environment that simulated the most frequently reported circumstances of falls, such as obstacles that are encountered while walking. In order to enhance the probability of success of such intervention programs, it may help to get a better understanding of why elderly fall over obstacles. The second aim of this thesis was to provide more knowledge about the characteristics of obstacle avoidance under time pressure and about the influence of divided attention and aging on this task. Finally, the ultimate goal of the prevention of falls is the prevention of fall injuries. The third aim of this thesis was to explore whether the practice of martial arts fall techniques could potentially contribute to the prevention of fall injuries in the elderlyRU Radboud Universiteit Nijmegen, 06 december 2005Promotores : Duysens, J.E.J., Mulder, T.W.134 p
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
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
