EFFICACIA E TOLLERABILITA' DELLA LAMOTRIGINA: REVISIONE DELLA LETTERATURA ED ESPERIENZA CLINICA PERSONALE
No full textQuality of life in young Italian patients with epilepsy.
No full textThe objective was to evaluate the quality of life of young Italian patients with epilepsy and to investigate the influence of epilepsy medical variables on patients' quality of life. The settings were the Department of Paediatrics, University of Padua; Children's Hospital Giovanni XXIII, Bari; and three schools of South Italy. A sample of 285 subjects was selected: 140 subjects affected by idiopathic and cryptogenic epilepsy (classified according to the International League Against Epilepsy criteria) and 145 control subjects. Data derived from the comparison between the two groups throughout "Epilepsy and children questionnaire" confirmed the negative epilepsy impact on the young patients' quality of life: in fact they scored significantly lower on psychological and social domains (p</=0.05) than the control group. The quality of life in children with epilepsy is significantly compromised. The questionnaire used in this study is a valid and reliable self-evaluation instrument that can improve clinical research on the quality of life in epilepsy
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
Spectral analysis of the eeg in paediatric anti-NMDAR encephalitis
No full textIt has been recently reported that the electroencephalographic (EEG) background activity in Anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis evolve in phases, paralleling the clinical course of the disease. Quantification of EEG changes may help to monitoring therapeutic interventions and to predict outcome but, the EEG spectral analysis has not yet been studied in this disorder. To contribute to characterize EEG activity in paediatric anti-NMDAR encephalitis is important using a quantitative approach. The EEG was recorded during sleep and wakefulness in 3 children in different clinical phases of the disease. The relative spectral power in the delta (0.5–4 Hz), theta (4–8 Hz), alpha (8 −13 Hz), and beta (13–30 Hz) frequency bands was calculated using the Fast Fourier Transformation and correlated with disease stages. The spectral EEG time was characterized in all patients by decrease in alpha power at occipital sites and widespread increase in theta and delta power prevalent at frontal locations. The reappearance of alpha power at occipital sites preceded clinical recovery. Spectral analysis of the EEG had an added value over traditional EEG on quantification of electrical changes and in short term outcome
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
