Exercise prescription in the treatment of type 2 diabetes – current practices, existing guidelines and future directions.
No full textExercise is an effective treatment for type 2
diabetes mellitus, resulting in stabilization of plasma glucose
in the acute phase and improvements in body composition,
insulin resistance and glycosylated haemoglobin
with chronic exercise training. However, the most appropriate
exercise prescription for type 2 diabetes has not yet
been established, resulting from insufficient evidence to
determine the optimum type, intensity, duration or frequency
of exercise training. Furthermore, patient engagement
in exercise is suboptimal. There are many likely
reasons for low engagement in exercise; one possible
contributory factor may be a tendency for expert bodies to
prioritize the roles of diet and medication over exercise in
their treatment guidelines. Published treatment guidelines
vary in their approach to exercise training, but most
agencies suggest that people with type 2 diabetes engage in
150 min of moderate to vigorous aerobic exercise per
week. This prescription is similar to the established
guidelines for cardiovascular health in the general population.
Future possibilities in this area include investigation
of the physiological effects and practical benefits of exercise
training of different intensities in type 2 diabetes, and
the use of individualized prescription to maximize the
health benefits of training

Full text linkMeasures of static postural control moderate the association of strength and power with functional dynamic balance
No full textAge-related reductions in strength and power are considered to negatively impact balance control, but the existence of a direct association is still an issue of debate. This is possibly due to the fact that balance assessment is complex, reflects different underlying physiologic mechanisms and involves quantitative measurements of postural sway or timing of performance during balance tasks. The present study evaluated the moderator effect of static postural control on the association of power and strength with dynamic balance tasks
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
