S.V.E.B.A. una scala per la valutazione del benessere emotivo dell’anziano
No full textThe “Scala di Valutazione dell’Emotività e del Benessere dell’Anziano” (SVEBA) (Evaluation Scale of Affectivity and Well-Being in the Elderly) is a psychometric tool consisting of 15 “yes/no” questions, devised for the rapid clinical screening of affective disorders. A validation study of the scale matched the SVEBA score and both the interview evaluation and the Symptoms Rating Test score (SRT-Italian validated form). The subjects (321 volunteers) were distributed according to essential socio-demographic characteristics of the Italian population. The results confirmed a high concomitant validity with respect to both SRT and clinical evaluation, although with respect to the latter it revealed less specificity. In two subsequent trials with out-patients and long-term hospitalized patients, the SVEBA scale showed a high degree of empirical validity and a satisfactory sensitivity also in the case of slight-mild cognitive deficit. The presence of medical illness appeared to be unrelated to the affective distress quantified by the SVEBA scale

No full textRating scales in the assessment of affective disorders of the aged are widely used, but Italian versions of these instruments are lacking. In literature two 15-items evaluation schedules, both derived from MMPI and validated in aged people, may be found. A study was designed to assess whether their Italian versions behave in the same manner in classifying the sample (590 aged subjects, males and females) and whether concomitant variables (age, sex, physical fitness, etc.) may be source of variability. Final results showed that sex only was a significant source of variability for both scales, besides the sample was classified into two main groups (normal and psychopathological) without significant difference. A discriminant analysis on the scores showed that in both scales six items only had the main right classification power
La scala S.V.E.B.A. per la misurazione dello stato emotivo-affettivo dell’anziano
No full textThe paper presents the first step analysis of data collected to build up a psychometric tool, consisting of 15 “yes/no” questions and termed “Scala di Valutazione dell’Emotività e del Benessere dell’Anziano” (SVEBA) (Evaluation Scale of Affectivity and Well-Being in the Elderly), aimed at a rapid clinical screening of affective disorders. A validation study of the scale matched the SVEBA score and both the interview evaluation and the Symptoms Rating Test score of R. Kellner and B. F. Sheffield (SRT-Italian validated form). The sample was constituted by 321 volunteers. The results confirmed a high concomitant validity with respect to both SRT and clinical evaluation. High correlations were observed between the two global measurements and for subgroups obtained by gender, residence area, age classes
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
