How to keep coronary artery disease patients active after the acute rehabilitation phase? The value of an internet-based telerehabilitation programme.
No full textBackground: Most cardiac patients return to their sedentary lifestyle after the acute rehabilitation phase. The aim of this study was to evaluate whether the addition of a motion sensor with automated feedback by e-mail or SMS to the conventional rehabilitation programme could result in an increase in daily activity among coronary artery disease patients. Methods: 20 coronary artery disease patients were included in this randomised, controlled trial after admission for PCI or CABG (target population of the study n=80). All patients were included during phase II of the cardiac rehabilitation programme. Patients with a defibrilator, important arrythmias or severe heart failure (NYHA class III and IV) were excluded from the trial. The patients in the intervention group(n=14) were asked to wear the motion sensor continuously during the day for 6 weeks. Each week they uploaded their step data on the web and received new step goals for the next week. The feedback programme was designed to gradually increase the patients' activity level. In the control group(n=6), the patients wore the motion sensor two times for one week for measurement purposes only(week 1 and 6). These sensors were taped, thereby making it impossible for the patients from the control group to monitor their daily activities. All patients performed a maximal cardiopulmonary exercise test at week 1 and 6 to determine their peak oxygen uptake(VO2-peak). The primary hypothesis of the trial was that the addition of a telerehabilitation programme to the conventional cardiac rehabilitation programme results in a sustained, increased amount of daily activity outside the rehabilitation centre. The secondary hypothesis was that this also would translate into a greater increase in VO2 peak. The Wilcoxon and Mann-Whitney test were used to test these hypotheses. Results: for the intervention patients, the Wilcoxon test showed a significant increase in daily activity between week 1 and week 6 (P=0,0009) and a significant increase in VO2peak (P=0,0098). In the control group, the respective P values were 0,219 and 0,375. The Mann-Whitney test comparing the increase in walking steps from week 1 to week 6 between the intervention and control group did also show a trend toward larger increase in the intervention group(P=0,054). Conclusions: The addition of an internet-based telerehabilitation programme to conventional cardiac rehabilitation resulted in a significant increase in daily activity level and VO2 peak after 6 weeks, as compared to conventional rehabilitation alone. This observation was promising because it has proven difficult to encourage cardiac patients to stay active or to increase their daily physical activity level. An internet-based telerehabilitation intervention that uses motion sensors might be a valuable instrument to overcome this difficulty

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
