No full textBackground. The objective of this work is to analyze the activity of the general hospital psychiatric inpatient service in Varese in the period between 1978 and 1992. Materials and methods. Some indices of psychiatric service utilization called 'utilization indicators' (first admissions, total admissions, days of stay, number of admitted patients) and some indices of intensity of service utilization called 'flow indicator' (average lenght of stay, index of bed occupation, index of turnover, have been used. Results. Though considering that the general hospital psychiatric Inpatient service in Varese has always maintained a considerable activity, the results have pointed out, as to the indices of service utilization, some moments of greater activity especially in the years immediately following the institution of psychiatric inpatient services and in the quadriennium 1984- 1987. Conclusions. As to the indices of intensity of service the period of largest activity was registered in the last quadriennium of the period examinated. Then we compared our results with those of Pavia's area, where a similar research was conducted, with the results of Crema's and Cremona's area and those of Mantova's area
Evaluation of positive and negative symptoms in chronic schizophrenia: An interrelationship study among SANS/SAPS, PANSS and InSka rating scales
No full textAim. The aim of the study was to evaluate the degree of statistic correlation of some of the best known instruments used for the assessment of the positive and negative symptomatology of schizophrenic patients. Methods. The evaluation rating scales PANSS, SAPS/SANS and InSka in the Italian version have been used. The scales have been submitted, through the joined interview method, to 28 DSM-IV schizophrenic patients living in some community units of our department, with at least 5 year illness. We have used the scores resulting from the submission of each rating scale to get to the definition of the syndrome diagnosis following the rules stated by each author. We have then compared these diagnosis (syndromic diagnosis interrelation), the simple scores of each subscale (subscale interrelation) and the subscales of PANSS and SAPS/SANS for the structure correlation evaluation. Results. A substantial positive correlation among the tools used has been noticed. This correlation was higher for the negative syndrome diagnosis (Spearman's p=0.503; P<0.01) and for the correlation between the subscales evaluating the negative symptoms (Pearson's r=0.668; P<0.01). The correlation between very different instruments such as the scale of evaluation of the apathy syndrome and the scale of evaluation of the PANSS general psychophatology has proved statistically significant (Pearson's r=0.689; P<0.01). Conclusion. Even if based on a poor sample, the results seem to support the research hypothesis and to confirm the litterature data. On the basis of our experience we can confirm the validity of the support given by these instruments both in research and in clinical practice
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
