Worsening in seizure frequency and severity in relation to folic acid administration
No full textWe report a case of increase in seizure frequency and severity in a 26-year-old woman receiving folic acid at a dosage of 0.8 mg/day. She had symptomatic partial epilepsy with simple and complex seizures treated with carbamazepine. She was planning pregnancy and we prescribed folic acid for prevention of neural-tube defects. In the next few days she had a generalized tonic-clonic seizure for the first time and a significant increase in seizure frequency. Because of the temporal relation between the seizure worsening and the administration of folic acid, we hypothesize a role of folic acid in provoking seizures, as has been reported in the literature
Felbamate in refractory partial epilepsy
No full textThis open-label study was performed to evaluate efficacy and safety of Felbamate (FBM) add-on therapy in drug-refractory partial epilepsy. We evaluated 36 patients (12 males) aged 11-68 years (mean 29.8) in which FBM was titrated gradually from 300 mg/day to a mean total maintenance daily dose of 1936 mg. Patients were monitored according to clinical practice and performed regularly laboratory tests. Mean follow-up of FBM therapy was 10 months (range 2-27). In this study, 5% of patients resulted to be seizure-free, 11% showed a seizure reduction more than 75%, 23% decreased their seizure frequency between 50% and 75% (P = 0.0001). The adverse events which were reported more frequently were: nausea, vomiting, anorexia and weight loss. Even if the patients sample is small FBM proves its efficacy in partial epilepsy, showing a relatively well tolerated profile
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
I pavimenti delle fabbriche reali milanesi. Manutenzioni tra la fine del XVIII e la metà del XX secolo
No full textIl saggio riguarda i pavimenti del tardo Settecento e del primo Ottocento nelle Fabbriche Reali di Milano e Monza. Vengono analizzati i materiali, le tecniche costruttive, le finiture, le attività di manutenzione e di restauro di questi pavimenti, che potevano essere di cotto, di legno (parquets), od anche i cosiddetti seminati alla veneziana, formati da graniglia di marmi di diversi colori, trattati con olio di lino e cera. Vengono tra l'altro documentati alcuni interventi di rinnovamento dei secoli XIX e XX
