Metabolic Syndrome: Gender Differences
Full text linkMetabolic syndrome is commonly defined as the association
of multiple risk factors for the development of atherosclerotic
disease. Despite the different definitions of diagnostic criteria,
the presence of at least three of the following conditions defines
the clinical presentation of the metabolic syndrome: atherogenic
dyslipidemia (low levels of HDL cholesterol, high levels of
triglycerides, apolipoprotein B and small and dense LDL), basically
high levels of systolic and diastolic blood pressure, impaired
fasting glycemia and abdominal obesity [1]. Primary pathogenic
mechanisms underlying metabolic syndrome are mainly due to
insulin resistance (or poor insulin sensitivity) and visceral obesity.
Insulin resistance, a condition where insulin determines a lower
biological effect than expected, is largely represented in patients
with metabolic syndrome and it is associated with a high risk of
developing type 2 diabetes in the short term. Obesity and physical
inactivity represent predisposing conditions for the development
of metabolic syndrome and perhaps represent the main mechanism
underlying the epidemic of metabolic syndrome, as observed in
recent years
The founder of a key European association
Full text linkFemale cardiologists prepared to sacrifice a family for a career are doing well in Italy,
according to Maria Grazia Modena, MD, FESC, past-president of the Italian Society
of Cardiology and chief, Institute of Cardiology, University of Modena and Reggio
Emilia, Italy. But she is frustrated that some of her colleagues seem more interested
in medical politics than cooperation. She talks to Barry Shurlock, MA, Ph
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
