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

Nonalcoholic fatty liver disease and the metabolic syndrome
No full textAbstract
Purpose of review Clinical, epidemiological and biochemical data strongly support the concept that nonalcoholic fatty liver disease (NAFLD) is the hepatic manifestation of the metabolic syndrome. Insulin resistance is the common soil connecting obesity, diabetes, hypertension and dyslipidemia with fatty liver and the progression of hepatic disease to steatohepatitis, fibrosis, cirrhosis and hepatocellular carcinoma.
Recent findings The association of NAFLD with the features of the metabolic syndrome has been confirmed in several epidemiological studies. The diagnostic and clinical significance of raised liver enzymes has been questioned; advanced hepatic disease may also be present in subjects with ultrasonographycally detected steatosis and normal aminotransferase levels. The role of adipokynes (leptin, adiponectin) and cytokines (tumor necrosis factor-a, interleukin-6, transforming growth factor-b) in disease progression is probably pivotal, mediated by oxidative stress. The importance of iron accumulation in this process has not been confirmed. Treatments aimed at weight loss remain a primary option; among pharmacological interventions insulin sensitizers (glitazones and metformin) have confirmed beneficial effects on both biochemical and histological data, but new treatments are on the horizon.
Summary NAFLD prevalence in western countries is high, and there is a trend towards a further increase, with millions people at risk of advanced liver disease. The epidemiological evidence, the lifestyle origin of the disease and the cost of pharmacotherapy make prevention a primary goal, and will contribute to make behavior therapy the background treatment. We need specific programs and carefully controlled, randomized studies to tackle simultaneously all the components of the metabolic syndrome
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
La Depressione Perinatale Paterna
No full textIl termine Depressione Perinatale Paterna (Paternal Perinatal Depression, PPND) indica la manifestazione nel padre di una sintomatologia depressiva nel periodo che va dall’inizio della gravidanza al primo anno dopo il parto (Baldoni, Ceccarelli, 2010, 2013). Nonostante questa condizione clinica sia nota da tempo, una diagnosi specifica è stata proposta per la prima volta solo alcuni anni fa nella letteratura francese di orientamento psicoanalitico (Luca, Bydlowski, 2001). La diagnosi di PPND è preferibile a quella di Depressione Postpartum Paterna (Paternal Postpartum Depression) o di Depressione Perinatale Paterna (Paternal Postnatal Depression), in quanto la ricerca ha evidenziato come queste condizioni cliniche si manifestino spesso molto prima del parto, per quanto la sintomatologia si protragga nel periodo postnatale. I disturbi affettivi perinatali paterni più lievi vengono a volte indicati con il nome di Paternal Blues (o Baby Blues). La PPND va distinta dalla Sindrome della Couvade, caratterizzata dalla manifestazione nel padre di sintomi somatici di entità lieve e di comportamenti femminili tipici della gravidanza che assumono raramente un valore psicopatologico preoccupante.
I sintomi della PPND tendono a presentarsi in modo differente rispetto a quelli della Depressione Perinatale Materna (Maternal Perinatal Depression, MPND), nonostante il periodo di esordio e la durata possano essere gli stessi. La sintomatologia depressiva paterna tende ad essere più lieve e meno definita di quella materna e spesso si presenta in comorbilità con altre sindromi, anche gravi, la cui sintomatologia può sovrapporsi a quella affettiva, oppure mascherarla, generando quadri clinici complessi

Paternal Perinatal Depression
No full textPaternal Perinatal Depression (PPND) refers to the onset of depressive symptoms in fathers from pregnancy to the first post-partum year (Baldoni, Ceccarelli, 2010, 2013). Although this clinical expression has been known for several decades, a specific diagnosis was suggested for the first time only a few years ago in the French psychoanalytic-oriented literature (Luca, Bydlowski, 2001). A diagnosis of PPND is preferable to that of Paternal Postpartum Depression or Paternal Postnatal Depression, since clinical onset appears to occur long before the baby’s birth, although the symptoms tend to last throughout the 12 months postpartum period. Less severe affective disorders in fathers have been described sometimes as Paternal Blues or Baby Blues. PPND differs from Couvade Syndrome which is characterized by mild somatic symptoms and typical female pregnancy behaviour that rarely develops into a worrying psychopathology.
Symptoms of PPND are different from those of Maternal Perinatal Depression (MPND), even if time of onset and duration of the disease may be the same. Depressive symptoms in fathers are generally milder and less defined than in mothers and often occur in comorbidity with other syndromes whose symptoms could overlap with the affective one, or mask it, causing complicated clinical pictures
