L'approccio interattivo-dinamico allo sviluppo e alla clinica delle relazioni
No full textIl capitolo presenta i costrutti fondamentali dell'approccio interattivo-dinamico allo studio delle interazioni precoci tra il bambino e gli adulti che si prendono cura di lui nelle fasi precoci dello sviluppo. Vengono presentati gli studi dell'infant research che utilizzano tale approccio nell'osservazione delle traiettorie evolutive nella prima infanzia e degli eventuali fattori di rischio ad esse connesse. Inoltre sono descritte le applicazioni di questo modello all'assessment del bambino e all'intervento precoce
Geriatric Nutritional Risk Index and overall-cause mortality prediction in institutionalised elderly : a 3-year survival analysis
No full textBackground & aims: A new tool, the Geriatric Nutritional Risk Index (GNRI), was recently proposed to predict short-term complications in elderly medical patients but no information is available when long-term follow-up periods are considered. Methods: A 3-year follow-up study in 245 institutionalised elderly (51 M:194 F; 83.7 ± 8.6 years). Nutritional risk was graded by GNRI (severe, 98). Main outcome was overall-cause death. Results: After the follow-up 99 (26 M:73 F) events occurred. Nutritional risk prevalence was 5.7%, 24.1%, 34.7% and 35.5% and mortality rates were 71.4%, 48.6% 33.7% and 34.3% with the GNRI 98, respectively. Kaplan-Meier curves were significantly associated to GNRI (p = 0.0068). GNRI 98. Similar results were confirmed by Cox regression (hazard ratio, HR = 2.76 [95%CI: 1.89-4.03], p = 0.0072). Finally, when "severe" and "moderate" risk were analysed as a single class (GNRI < 92) outcome associations were: OR = 2.17, [95%CI: 1.10-4.28] (p = 0.0245); HR = 1.76 [95%CI: 1.34-2.23] (p = 0.0315). Survival analysis showed higher mortality rates by GNRI < 92 (p = 0.0188). Conclusions: Present data support the use of the GNRI in the evaluation of long-term nutrition-related risk of death. We suggest a GNRI < 92 as clinical trigger for nutritional support in institutionalised elderly

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

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
