    Leslie Kaplan, l’esilio oltre l’esilio

    No full text
    Da L’Excès–l’usine ad Amants de Marie, a Mon Amérique commence en Pologne, Leslie Kaplan firma le pagine di un’«autobiografia probabile» che ha non poche similitudini con quella de l’enfant caché Georges Perec. È tuttavia solo nell’ultimo dei testi citati, uscito nel per la serie Depuis maintenant, che l’autrice insegue retrospettivamente il segreto delle proprie origini, rac- chiuso nella sintesi perfetta del suo nome: da un lato un patronimico ebraico che la àncora alla tragedia dei campi di concentramento, dall’altro l’eco del sogno americano di quei nonni miracolosamente emigrati in America prima della strage. Sospesa tra i due universi, la scrittrice non appartiene veramen- te a nessuna patria, se non a quella, dolorosa e bulimica, delle domande, magistralmente impersonata da «Mademoiselle je ne sais pas tout»

    The adverse event profile of pregabalin: A systematic review and meta-analysis of randomized controlled trials

    PURPOSE: Despite the widespread use of antiepileptic drugs (AEDs) across different neurologic and psychiatric disorders, no study has systematically reviewed all available randomized controlled trials (RCTs) of a given AED to fully uncover its tolerability profile. We aimed at identifying treatment emergent adverse events (AEs) associated with pregabalin through a systematic review and meta-analysis of all available RCTs. We also assessed the association between serious AEs and pregabalin, and investigated whether pregabalin AEs display a dose-response relationship. METHODS: We searched MEDLINE, EMBASE, and Cochrane CENTRAL to February 2010 for RCTs. Additional studies were identified from reference lists of retrieved papers and from online clinical databases. We selected placebo-controlled, double-blind RCTs investigating the therapeutic effects of pregabalin in adults with any condition. Studies had to include at least 20 subjects per arm and have a duration of at least 4 weeks. AEs were assessed for their association with pregabalin after identification/exclusion of synonyms, rare AEs, and nonassessable AEs due to methodologic limitations. We used relative risks (RRs) to assess the association of any [99% confidence intervals (CIs)] or serious AEs (95% CIs) with pregabalin, and risk differences (RDs, 95% CIs) to investigate dose-response relationships of pregabalin AEs. KEY FINDINGS: Thirty-eight RCTs were included in our study. Of 39 AEs, 20 (51%) were significantly associated with pregabalin (dizziness, vertigo, incoordination, balance disorder, ataxia, diplopia, blurred vision, amblyopia, tremor, somnolence, confusional state, disturbance in attention, thinking abnormal, euphoria, asthenia, fatigue, edema, peripheral edema, dry mouth, constipation). The highest RRs were found for cognition/coordination AEs. There was no significant association between serious AEs and pregabalin. There was a selective dose-response pattern in the onset of pregabalin AEs, with certain AEs appearing at lower doses than others. SIGNIFICANCE: Individuals starting treatment with pregabalin are at increased risk for several AEs, particularly those affecting cognition/coordination. Pregabalin AEs appear according to a selective dose-response pattern, possibly reflecting the severity of dysfunction of distinct anatomic structures. These findings may aid clinicians in providing better patient management, and support the value of including in meta-analyses of AED tolerability profiles RCTs performed in different condition

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    Polypoid angiomyofibroblastoma-like tumor of the oral cavity: a hitherto unreported soft tissue tumor mimicking embryonal rhabdomyosarcoma.

    We report on a previously unrecognized fibro-myofibroblastic tumor in the oral cavity of a 15-year-old girl. Morphologically, the tumor mimicked a rhabdomyosarcoma, botryoid variant. It was composed of mitotically active small- to medium-sized, vimentin+/desmin+, round- to oval- to epithelioid-shaped cells embedded in an alternating fibrous to myxoid/edematous stroma. These cells were separated from the overlying squamous epithelium by a rim of fibrous stroma. The tumor contained abundant small- to medium-sized, thin-walled blood vessels without hyalinization. Frequently, neoplastic cells condensed around these vessels. An unusual and striking feature was the presence of numerous hyalinized collagen mats, including "amianthoid-like fibers", similar to those observed in myofibroblastomas. The presence of these collagen mats and the expression of desmin, in association with no immunoreactivity to myogenin and MyoD1, were in keeping with the fibro-myofibroblastic nature of the tumor, excluding the diagnosis of embryonal rhabdomyosarcoma. Regarding fibro-myofibroblastic tumors, we believe that the present case falls within the wide spectrum of benign stromal tumors, originally described in the lower female genital tract, but potentially occurring also at extragenital sites. As morphological and immunohistochemical features were reminiscent of, but not identical with, angiomyofibroblastoma, the term "polypoid angiomyofibroblastoma-like tumor" is proposed. Awareness and recognition of this tumor is crucial to avoid a diagnosis of malignancy

    Variations on the Author

    “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

    Get PDF
    We 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

    Get PDF
    We 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
