Primi risultati di un’analisi multidisciplinare di un femore umano associato ai livelli del Musteriano finale (Foyer B) della Grotta del Principe di Monaco (Ventimiglia, IM, Italia).
No full textDurante le campagne di scavo condotte tra il 1895 e il 1902, nella Grotta del Principe di Monaco (Ventimiglia, Imperia, Italia) venne alla luce un frammento di osso lungo (PM-F-3034) dai livelli tardo-musteriani della stratigrafia (Foyer B), attribuiti al MIS4. Questo reperto è rimasto per molto tempo conservato e non identificato nel Museo di Antropologia preistorica del Principato di Monaco, fino alla sua “riscoperta” da parte del Dr. Abdelkader Moussous, durante l’analisi dei resti di grandi mammiferi delle Grotte dei Balzi Rossi, nell’ambito della sua tesi di dottorato (2014); il reperto venne già allora riconosciuto come un resto umano. Al fine
di identificarne la corretta determinazione anatomica, l’appartenenza tassonomica e, di conseguenza, comprenderne la relazione con il contesto musteriano associato, si è proceduto all’acquisizione tramite tomografia computerizzata ospedaliera (TC) con conseguenti elaborazioni digitali. Le analisi hanno evidenziato una forte alterazione corticale causata da particolari processi tafonomici avvenuti nel corso del tempo. L’elaborazione virtuale della diafisi umana, riconosciuta come femore (PM-F-3034), ha permesso di condurre analisi morfometriche non invasive (diametri antero-posteriori e medio-laterali, lunghezza biomeccanica, area midollare e corticale, indice pilastrico) (Caffarone, 2020), volte a identificare l’attribuzione tassonomica di questo individuo. Inoltre, considerando la posizione stratigrafica e lo stato di conservazione del resto umano, si è deciso di procedere con l’attribuzione cronologica al
radiocarbonio (14C), previo rilevamento di collagene tramite analisi microspettroscopica NIR (microNIR) (Catelli et al., 2020). Contrariamente a quanto ci si poteva aspettare, i valori ottenuti attraverso le analisi virtuali attribuiscono il femore a un individuo appartenente a Homo sapiens, esito confermato anche dall’analisi al 14C che lo colloca cronologicamente nel XV secolo. Questi risultati sottolineano la complessità stratigrafica della Grotta del Principe di Monaco, evidenziando occupazioni diacroniche sin da periodi relativamente recenti. In conclusione, questo studio ha dimostrato che l’analisi antropologica dei resti fossili, unitamente all’analisi al 14C, è fondamentale per una corretta attribuzione crono-tassonomica, compensando le incertezze e le alterazioni indotte durante l’attività di scavo, oltre a quelle prodotte da processi diagenetici che possono aver generato un parziale rimescolamento sedimentario.During the excavation campaigns occurred between 1895 and 1902, a fragment of a long bone (PM-F-3034) was discovered in the late Mousterian levels of the stratigraphy (Foyer B), attributed to MIS4, in the Prince of Monaco’s Cave (Ventimiglia, Imperia, Italy). This find remained for a long time stored but unidentified in the Museum of Prehistoric Anthropology of
the Principality of Monaco until its “rediscovery” by Dr. Abdelkader Moussous, during the analysis of large mammal remains from the Balzi Rossi caves, as part of his PhD thesis (2014); in this circumstance the fragment was recognized as a human remain. In order to identify its correct anatomical determination, its taxonomy and, consequently, to understand its relationship with the associated Mousterian context, it was acquired by hospital computed tomography (CT) with subsequent digital processing. The analysis showed a strong cortical alteration, caused by taphonomic processes that occurred over time. Virtual processing of the human diaphysis, recognized as a femur (PM-F-3034), allowed to conduct non-invasive morphometric analyses (antero-posterior and medio-lateral diameters, biomechanical length, medullary and cortical area, pilastric index) (Caffarone, 2020) aimed to identify the taxonomic
attribution of this individual. Furthermore, considering the stratigraphic position and the state of preservation of the human remain, it was decided to proceed with 14C chronological attribution, preceded by the collagen detection by microspectroscopic NIR (microNIR) analysis (Catelli et al., 2020). Contrary to what might have been expected, the values obtained through the virtual analysis attribute the femur to Homo sapiens and it is also confirmed by 14C, that place the human bone chronologically in the 15th century. These results underline the stratigraphic complexity of the Prince of Monaco’s Cave and highlighting diachronic occupations since relatively recent periods. In conclusion, this study has shown that the anthropological analysis of fossil remains, along with 14C, is fundamental for a correct chrono-taxonomic attribution, compensating for the uncertainties and alterations induced during
excavation activities, as well as those produced by diagenetic processes that may have generated a partial sedimentary mixing
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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 PDFWe 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 PDFWe 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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
