The circumstances of falls among people with Parkinson's disease and the use of Falls Diaries to facilitate reporting
No full textPurpose: falls are common in Parkinson's disease (PD). Falls Diaries are one way of recording fall frequency and the surrounding circumstances; completing them encourages recall, and their content focuses intervention. We reviewed the diaries completed by people with PD during a randomized controlled trial (RCT) of fall prevention to ascertain the key circumstances surrounding falls.Method: we asked independently mobile, cognitively intact people with a diagnosis of PD to maintain a Falls Diary throughout a six-month RCT. We sent monthly diary sheets on which to answer questions about the 'Location', 'Fall-related activity', 'Perceived cause', 'Landing' and 'Consequences' of every fall. We coded responses and counted frequencies.Results: of the 142 RCT participants (mean age 72 years; mean years since diagnosis 8), 135 completed the trial and their diary. We excluded 11 (8%) for missing data and/or unintelligible writing. The 124 remaining diaries recorded 639 falls: 80% happened at home, commonly in bedrooms, living areas, kitchens and gardens. Fallers had been ambulant in 45% of events, standing in 32% and transferring in 21%. Six 'activity-cause combinations' accounted for 55% of falls (tripping 13%; freezing, festination and retropulsion 11%; and postural instability when bending or reaching 9%, transferring 8%, walking 7% and washing or dressing 7%). Misjudgement and distraction played a part in 12% of falls described.Conclusions: of over 600 falls surveyed, most happened at home, provoked by postural instability, tripping and freezing. Environmental adaptation and cognitive training should be trialled in falls prevention in PD, plus or minus traditional movement rehabilitation. Most participants completed Falls Diaries successfully. We advocate diary use, with follow-up interviews, in research and clinically. People with handwriting difficulty may require a typed diary, proxy diarist or intervie
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
A randomised controlled trial of a home based exercise programme to reduce the risk of falling among people with Parkinson’s disease
No full textObjective: to evaluate the effectiveness of a personalised home programme of exercises and strategies for repeat fallers with Parkinson’s disease (PD).Method: patients with a confirmed diagnosis of idiopathic PD, independently mobile, living at home in the community, experiencing more than one fall in the previous 12 months and with intact gross cognitive function were invited to participate in this randomised controlled trial. Usual care was compared with a personalised 6 week, home based exercise and strategy programme. The primary outcomes were rates of falling at 8 weeks and 6 months. Whether participants had repeat fallen, nearly fallen or experienced injurious falls were also examined. Functional Reach, the Berg Balance Test, PD Self-assessment Scale and the Euro Quol were rated by a blinded assessor.Results: participants were randomised to the exercise (n?=?70) and control (n?=?72) groups. There was a consistent trend towards lower fall rates in the exercise group at both 8 weeks and 6 months and lower rates of injurious falls needing medical attention at 6 months. Lower rates of repeat near falling were evident for the exercise group at 8 weeks (p?=?0.004) and 6 months (p?=?0.007). There was a positive effect of exercises at 6 months on Functional Reach (p?=?0.009) and quality of life (p?=?0.033). No significant differences were found on other secondary outcomes measures.Conclusion: there was a trend towards a reduction in fall events and injurious falls with a positive effect of exercises on near falls and quality of lif
