    L’osservazione dei danni provocati da un terremoto è spesso differente nello stesso centro abitato. La causa va ricercata, oltre che nella diversa qualità e tipologia delle strutture abitative, in una differente pericolosità sismica del territorio a scala locale. La microzonazione sismica è uno strumento di valutazione della pericolosità connessa ai rischi geologici in aree urbane, è inoltre un supporto alla pianificazione del territorio ed alle relative misure di prevenzione; in tale ottica si configura come strumento di riduzione del rischio sismico. L'obbiettivo del lavoro ha riguardato la messa a punto di un sistema di gestione per l'individuazione di aree omogenee in prospettiva sismica nei territori dei Comuni della Provincia di Foggia suddividendoli in zone stabili, zone stabili suscettibili di amplificazione locale e in zone instabili attraverso l'analisi di dati di natura geologica, geofisica e geomorfologica, secondo quanto previsto dalle specifiche degli Indirizzi e Criteri per la microzonazione sismica (Gruppo di lavoro MS 2008). Il prodotto finale è stato la realizzazione di un geodatabase ESRI® sviluppato in ambiente ESRI ArcMap ® contenente i dati di sottosuolo, le aree degli affioramenti geo-litologici e le aree delle microzone omogenee in prospettiva simica corredato con i relativi layout cartografici dei territori urbani selezionat

    Purpose of reviewNeurogenic dysphagia worsens quality of life and prognosis of patients with different neurological disorders. Management of neurogenic dysphagia can be challenging. This review provides a comprehensive overview of current evidence on screening, diagnosis, and treatment of neurogenic dysphagia in stroke and Parkinson's disease, suggesting clues for clinical practice.Recent findingsThe pros and cons of diagnostic techniques are discussed in the light of updated evidence. Findings from recent meta-analyses of different treatment approaches, including traditional dysphagia therapy, peripheral and central neurostimulation techniques, and treatment with botulinum toxin, are critically discussed, emphasizing inconsistencies and controversial issues.Screening tests and clinical swallow examination should be routinely performed in neurological patients at risk for dysphagia. In patients testing positive for dysphagia, first-line instrumental investigations, represented by fiberoptic endoscopic evaluation of swallowing or videofluoroscopic swallow study, should be performed to confirm the presence of dysphagia, to assess its severity, and to inform the treatment. Second-line and third-line instrumental methods can be used in selected patients to clarify specific pathophysiological aspects of oropharyngeal dysphagia. Treatment strategies should be personalized, and combination of traditional dysphagia therapy with innovative treatment approaches may increase the chance of restoring effective and safe swallowing

    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

    External anal sphincter electromyography in multiple system atrophy: implications for diagnosis, clinical correlations, and novel insights into prognosis

    No full text
    Multiple system atrophy is a sporadic, progressive, adult-onset, neurodegenerative disorder characterized by autonomic dysfunction symptoms, parkinsonian features, and cerebellar signs in various combinations. An early diagnosis of multiple system atrophy is of utmost importance for the proper prevention and management of its potentially fatal complications leading to the poor prognosis of these patients. The current diagnostic criteria incorporate several clinical red flags and magnetic resonance imaging markers supporting diagnosis of multiple system atrophy. Nonetheless, especially in the early disease stage, it can be challenging to differentiate multiple system atrophy from mimic disorders, in particular Parkinson’s disease. Electromyography of the external anal sphincter represents a useful neurophysiological tool for differential diagnosis since it can provide indirect evidence of Onuf’s nucleus degeneration, which is a pathological hallmark of multiple system atrophy. However, the diagnostic value of external anal sphincter electromyography has been a matter of debate for three decades due to controversial reports in the literature. In this review, after a brief overview of the electrophysiological methodology, we first aimed to critically analyze the available knowledge on the diagnostic role of external anal sphincter electromyography. We discussed the conflicting evidence on the clinical correlations of neurogenic abnormalities found at external anal sphincter electromyography. Finally, we reported recent prognostic findings of a novel classification of electromyography patterns of the external anal sphincter that could pave the way toward the implementation of this neurophysiological technique for survival prediction in patients with multiple system atrophy

    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

    Full text link
    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

    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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
