Subjective quality of life: its relationship with clinician-rated and patient-rated psychopathology. The South Verona Outcome Project 6.
No full textBackground. The study compared clinician-rated and patient-rated psychopathology and analysed their relationship with subjective quality of life (QoL) in a sample of patients with a wide range of psychiatric conditions attending a community-based mental health service. Methods: In the context of the South-Verona Outcome Project (SVOP), 139 patients were assessed for both clinician-rated and self-rated psychopathology (by using respectively the Brief Psychiatric Rating Scale and the revised version of the Symptom Checklist 90), and asked to report on their subjective quality of life (by using the Lancashire Quality of Life Profile). In order to explore the associations between psychopathology and subjective QoL bivariate and multivariate analyses were performed. Results: BPRS and SCL-90-R were poorly correlated, both in their total scores and in their various dimension scores. BPRS showed only a modest negative correlation with LQL, which, in contrast, was highly negatively correlated with SCL-90-R. Regression analyses showed that patient-rated psychopathology was the strongest predictor of subjective quality of life, with self-rated depressive symptoms and self-reported paranoid ideation having the highest predictive power. Conclusions: Self-reported psychological distress is more important than clinician-rated symptom severity in predicting subjective QoL. In order to improve QoL, psychiatric treatment should focus not only on simple reduction of symptoms but also on patients' subjective psychological distress
DART: De-Anonymization of personal gazetteers through social trajectories
No full textThe interest in trajectory data has sensibly increased since the widespread of mobile devices. Simple clustering techniques allow the recognition of personal gazetteers, i.e., the set of main points of interest (also called stay points) of each user, together with the list of time instants of each visit. Due to their sensitiveness, personal gazetteers are usually anonymized, but their inherent unique patterns expose them to the risk of being de-anonymized. In particular, social trajectories (i.e., those obtained from social networks, which associate statuses and check-ins to spatial and temporal locations) can be leveraged by an adversary to de-anonymize personal gazetteers. In this paper, we propose DART as an innovative approach to effectively de-anonymize personal gazetteers through social trajectories, even in the absence of a temporal alignment between the two sources (i.e., they have been collected over different periods). DART relies on a big data implementation, guaranteeing the scalability to large volumes of data. We evaluate our approach on two real-world datasets and we compare it with recent state-of-the-art algorithms to verify its effectiveness
La Qualita’ di Vita dei Pazienti Psichiatrici. Monograph Supplement 4 Epidemiologia e Psichiatria Sociale
No full textLa ricerca psichiatrica ha investito molte risorse per definire in termini operazionali i sintomi, le diagnosi, il funzionamento sociale dei pazienti. Ha invece sino ad aora sottovalutato la soggettività, cioè l'esperienza della malattia e delle conseguenze determinate dalla malattia nella vita di un paziente, che è fonte esssenziale di conoscenze per la comprensione dei fenomeni patologici. Scopo di questa monografia è prendere in considerazione uno di questi parameri: la qualità della vita. Nella Prima Parte vengono riassunti aspetti generali della concettualizzazione e misurazione di questa variabile. Nella Seconda viene presentato uno studio sperimentale condotto presso il Servizio Psichiatrico Territoriale di Verona Su
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
