Forensic radiology and personal identification of unidentified bodies: a review = Radiologia forense ed identifi cazione personale dei cadaveri: revisione della letteratura
No full textL’identificazione personale dei cadaveri senza identità è cruciale per motivi etici, giuridici e civilistici, e viene eseguita tramite un confronto fra i dati del profilo biologico ottenuti dal cadavere e il materiale ante mortem di uno o più sospetti d’identità o persone scomparse. Le crescenti applicazioni della radiologia forense e l’ampio uso della radiografi a tradizionale e della tomografi a assiale computerizzata (TAC) nella comune pratica clinica mostrano la potenziale importanza di tali tecnologie come strumento di verifica della corrispondenza fra un corpo senza identità ed un sospetto d’identità. Questo studio vuole esporre una revisione della letteratura riguardante l’applicazione della radiologia forense al complesso ambito dell’identificazione personale; nonostante la crescente importanza del confronto fra radiografi e ed immagini TAC, numerosi limiti aspettano ancora di essere superati; al momento infatti pochi istituti di medicina legale hanno accesso agli strumenti radiografi ci più sofisticati, e sta sorgendo un ampio dibattito sulla reale affidabilità di tali tecniche nell’identificazione di specifici tratti morfologici e lesioni su osso. Inoltre, così come altri metodi identificativi basati sul confronto morfologico, anche il confronto fra dati radiografi ci ante e post mortem richiede una standardizzazione ed un approfondimento statistico, specialmente in Europa ove esistono pochissime indicazioni sulla modalità di ammissione di una prova scientifica ottenuta tramite metodi antropologici e radiologici in un processo. In futuro, con lo sviluppo delle tecnologie radiografi che e l’aumento del numero di studi riguardanti la loro applicazione a contesti forensi, la radiologia diverrà uno degli strumenti più utili nel campo dell’identificazione personale.Personal identification of unidentified bodies is crucial for ethical, juridical and civil reasons and is performed through comparison between biological data obtained from the cadaver and antemortem material from one or more missing persons to whom the body may have belonged in life. The increasing applications of forensic radiology and the wide use of conventional radiography and computed tomography (CT) in routine clinical practice demonstrate the potential of these technologies as tools for verifying the correspondence between an unidentified body and an identity suspect. This paper reviews the literature concerning the application of forensic radiology to the difficult issue of personal identification. Despite the increasing importance of the comparison between radiographic and CT findings, numerous limitations still need to be overcome, including the fact that few forensic centres have access to sophisticated X-ray technologies and that the reliability of those technologies for detecting specific morphological traits and bone lesions is a matter of intense debate. In addition, as with other morphological methods for identification, comparisons between antemortem and postmortem data require standardisation and statistical analysis, especially in Europe where there are very few indications concerning the admission in court of evidence obtained by anthropological and radiological methods. In the future, with developments in radiographic technologies and increasing numbers of studies on their application to the forensic setting, radiology will become one of the most useful tools in the field of personal identification
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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
Il grande traumatismo contusivo "a corpo libero" : contributi alla diagnosi differenziale tra precipitazione, investimento pedonale ed investimento di ciclista
No full textIl capitolo del grande traumatismo contusivo è sicuramente uno dei più importanti ed interessanti dell'intera patologia forense. I più noti trattati di argomento affrontano tale tematica, contrapponendo tradizionalmente il traumatismo da incidente del traffico a quello da precipitazione. Pare opportuno introdurre una seconda categorizzazione, che giustapponga il grande traumatismno > (precipitato, pedone, ciclista, ciclomotorista, motociclista) al grande traumatismo > (occupanti di veicoli). Il presente lavoro ha l'obiettivo di caratterizzare il pattern lesivo delle varie classi di vittime del grande traumatismo policontusivo > con l'eccezione di ciclomotoristi e motociclisti (già oggetto di precedente studio ed oggetto di futuri approfondimenti) mediante analisi crociata del quadro lesivo delle vittime. Una popolazione di 307 soggetti deceduti in seguito a precipitazione (Pr) ed autopsiati presso l'Istituto di Medicina Legale di Milano è stata analizzata in riferimento al quadro lesivo riportato
