Nutritional habits of subjects with Type 2 diabetes mellitus in the Mediterranean basin: comparison with the non-diabetic population and the dietary recommendations. Multi-centre study of the Mediterranean group for the study of Diabetes (MGSD)
Aims/hypothesis. The aim of this study was to compare
the nutritional habits of Type 2 diabetic patients
among Mediterranean countries and also with those of
their background population and with the nutritional
recommendations of the Diabetes and Nutrition Study
Group.
Methods. We did a cross-sectional study of 1833 nondiabetic
subjects and 1895 patients with Type 2 diabetes, in nine centres in six Mediterranean countries. A dietary questionnaire validated against the 3-Day Diet Diary was used.
Results. In diabetic patients the contribution of proteins,
carbohydrates and fat to the energy intake varied
greatly among centres, ranging from 17.6% to 21.0%
for protein, from 37.7% to 53.0% for carbohydrates
and from 27.2% to 40.8% for fat, following in every
centre the trends of the non-diabetic population. Furthermore, diabetic patients compared to the corresponding
background population had: (i) lower energy intake, (ii) lower carbohydrate and higher protein contribution to the energy intake, (iii) higher prevalence of obesity, ranging from 9 to 50%. The adherence to the nutritional recommendations for proteins, carbohydrate and fat was very low ranging from 1.4 to 23.6%, and still decreased when fibre was also considered.
Conclusion/interpretation. In diabetic patients of the
Mediterranean area: (i) dietary habits vary greatly
among countries, according to the same trends of the
background population; (ii) the prevalence of obesity
is much lower than the 80% reported for patients with
diabetes in Western countries; (iii) Carbohydrate intake
is decreased with a complementary increase of protein and fat consumption, resulting to a poor compliance with the nutritional recommendations
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
