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
Intensive aerobic training improves motor performances and oxidative metabolism efficiency in chronic polymyositis: A case report
No full textWe describe the case of a 64-year-old woman affected by chronic polymyositis with gait disturbance, fatty replacement and swelling of thigh muscles. She achieved significant clinical improvement after 5 weeks intensive aerobic training. In particular the patient improved in motor performance tests, showed an improvement in the efficiency of oxidative metabolism and quality of life. Furthermore, analysis of creatinephosphokinase levels showed a reduction of muscle damage susceptibility. In conclusion, a specific intensive exercise program can be safely used with beneficial effects on muscle function in patients with chronic polymyositis
Benefits of an intensive task-oriented circuit training in Multiple Sclerosis patients with mild disability
No full textBACKGROUND: Exercise is well tolerated and induces relevant improvements in physical and mental functioning of persons with Multiple Sclerosis (MS). Unfortunately, due to the wide variety of symptoms and the broad range of exercise interventions, it is not possible to make unified exercise recommendation as to what type of exercise is safe and effective for persons with MS.OBJECTIVE: The aim was to test the impact of an intensive task-oriented training on motor function and quality of life in 17 MS patients with an Expanded Disability Status Scale (EDSS) between 4 and 5.5.METHODS: Patients underwent a two-week intensive, task-oriented rehabilitation program. Outcome measures were: Berg Balance Scale, Gait Dynamic Index, 6 Minute Walking Test, Physiological Cost Index, Fatigue Severity Scale, 10 metres Walking Test, Timed Up and Go test, Short form 36, Multiple Sclerosis Impact Scale, Patient Health Questionnaire. RESULTS: All outcome measures showed a significant improvement after the treatment except for the 6 Minute Walking test and the Short form 36 that showed a trend of improvement although not statistically significant.CONCLUSIONS: An intensive task-oriented rehabilitation protocol is effective in improving motor function and has a positive impact on quality of life in MS patients with moderate disability
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
