Fattori cognitivi e fattori psicosociali nella comorbilità psichiatrica nei Disturbi Specifici di Apprendimento(DSA)

Clinical [eatures, which often are superimposable, lead to unspecified clinical pictures that could represent the first warning sign or the developemental's stratification oforiginal disorder. Starting about the comorbidity's concept we could better undersand the clinical pictures preamble and the reorganization ofprincipal syndromes. In this research, conducts on 101 children about 10,6 years old which are divided in two sectors: the clinical one and the unclinical, is valued the psychiatric comorbidity in people affect about specific learning disorders (DSA): it seek confermation in existing evidences and an association with problems that concerned the emotional, social and behavioural side, that exceed that of unaffecting people with speciiic learning disorder. It has been also analysed the comorbidity in relation with biopsychosocial's variables still less considerating in dirferent studies
Fighting against age discrimination in clinical trials
No full textAt the American Geriatrics Society 2008 Annual Meeting, representatives of two geriatric societies, the European Union Geriatric Medicine Societies and the American Geriatrics Society, and two regulatory agencies, the U.S. Food and Drug Administration and the European Medicine Agency, conducted a roundtable discussion aimed at reviewing the participation of older people in clinical trials. This article summarizes the important issues discussed at the meeting. Historically, regulatory agencies started to promote the inclusion of older participants in clinical trials in the late 1980s. The identification of the causes of delay in including older participants in clinical trials, as well as of the ongoing bias against including older participants with multiple comorbidities, is important to help geriatricians fight against age discrimination in clinical trials. To overcome this problem, geriatrics societies and regulatory agencies must work together to propose new definitions, study designs, and technologies aimed at improving the evaluation of drugs in older people with multiple comorbidities and polypharmacy

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
