Musculoskeletal pain & dysfunction in musicians
No full textIn the Netherlands more than 2 million people are actively making music. Unfortunately, thousands of these musicians experience pain in their muscles and/or tendons that limits them in practicing their hobby or profession. For professional musicians, these complaints can lead to temporary incapacity for work or even early termination of their career. It is not clear exactly what causes these complaints. The PhD thesis of rehabilitation physician Kees Hein Woldendorp focused on this type of complaints among musicians. Since professional musicians are engaged in intensive and long-term physical activities, it is obvious that physical factors play an important role in the development of complaints. Many health care providers assume that highly tensed muscles, insufficient relaxation, poor posture and/or little variation in workload leads to pain complaints. The first goal of the PhD project was therefore to examine these assumptions. The results did not confirm the assumptions. To enable further research, it is important to measure posture and motor function accurately. This is only possible to a limited extent for musicians, because not enough measuring instruments are available or applicable. This is why the second part of the thesis discusses research to gain more knowledge about practical and usable measuring instruments. The studies focused on the measurement of embouchure in wind instruments (how the flow of air through the mouth ensures the right sound), hand characteristics and posture. The insights and results from this PhD research will be used for further research and improving the rehabilitation of musicians with musculoskeletal complaints
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
Functional capacity evaluation in patients with chronic low back pain : reliability and validity
Full text linkPatients with chronic low back pain (CLBP) are limited in the performance of activities and may thus be (temporarily) incapacitated to work, resulting in work-absenteeism and work-disability. According to the ‘model of functional capacity and functional demands’, it was assumed that CLBP is caused by an imbalance between a person’s functional capacity and functional demands. Validated instruments to assess the individual components of the model are unavailable. This thesis has focussed on one of the components in the model: the assessment of functional capacity in patients with CLBP.
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
