Obesità e sovrappeso: dalla epidemiologia alle strategie di prevenzione.
No full textL’obesità può essere definita come un eccesso di accumulo di grasso corporeo che può determinare
conseguenze patologiche in diversi organi (apparato cardiovascolare, pancreas, fegato, apparato
respiratorio, apparato muscolo-scheletrico), così come nella sfera psichiatrica e nelle relazioni
sociali.Obesità e sovrappeso sono condizioni ormai universalmente riconosciute come fattori di rischio per
le principali malattie croniche: malattie cardiovascolari, ictus, diabete, alcuni tumori (endometriale,
colorettale, renale, della colecisti e della mammella in post-menopausa), osteoartriti, patologie del
sistema riproduttivo, patologie psichiatriche.Si è quindi visto che sovrappeso e obesità determinano problemi di importanza non tracurabile sul
piano della salute in senso stretto, della qualità della vita, delle relative ricadute economiche
personali e pubbliche. La World Health Organization, Regional Office For Europe, in occasione del
recente incontro Istanbul, Turchia, 15–17 Novembre 2006 ha stilato la Carta Europea sull’azione di
contrasto al sovrappeso e obesita
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Attempted suicides in the municipality of Padua (Italy): a retrospective survey (1996-2000)
No full textThis study was conduced to determine attempted suicide (AS) rates in Padua between 1996 and 2000, to compare them with Italy and other Veneto areas.
MATERIALS AND METHODS:
It's an analysis of Police and Carabinieri reports. For each case, they indicate age, sex, marital status, mental and physical disorders, emotional disorders, alcoholism, drug addiction and method of attempted suicide.
RESULTS:
The annual rate of AS between 1996-2000 ranged from 14.3 (1996) to 3 (2000) per 10(5) inhabitants, with the highest rates in early Autumn; 57.7% of suicide attempts involved females. There is a peak between ages 25 and 34 years, with a higher incidence among females (p < 0.05). Divorce and single status appear to be important risk conditions, especially in females. Mental disorders (especially depression) are the most important condition prior to AS. Both genders have attempted suicide especially by poisoning or falling.
CONCLUSION:
In Padua AS rates are rather high by comparison with the regional average, but lower than in Verona. Marital status and loneliness (with various age-related peculiarities) influence AS rates and relational problems, inability to overcome frustration (in 10-44 year-olds) may play an important part. The use of educational tools, beginning in the early school years is very important, paying special attention to personal and family distress
