Di alcune sepolture della necropoli di Pithekoussai, isola di Ischia, Napoli. Analisi preliminare dei resti odontoscheletrici umani di VIII-VII sec. a.C. dagli scavi Buchner 1965.1967
No full textL’archeologia funeraria degli ultimi cinquant’anni si è avvalsa del contributo offerto dallo studio dei resti scheletrici e dentali umani nell’analisi del complesso record sepolcrale antico, ove le stime del sesso biologico e dell’età alla morte degli individui rappresentano i primi e fondamentali parametri interpretativi di qualsiasi ricostruzione, interpretazione, ipotesi e teoria sulle caratteristiche bioculturali delle antiche popolazioni. Gli studi di antropologia scheletrica, grazie ad uno spettro analitico amplissimo, si configurano come passo ineludibile per la comprensione del rapporto tra le società dei vivi e il loro essere biologico nei campioni di mortalità. In quest’ottica, il presente contributo mira a delineare le principali caratteristiche biologiche del campione odonto-scheletrico umano proveniente dagli scavi Buchner 1965-1967 della necropoli di Pithekoussai, oggetto di uno studio antropologico in fieri che pone come principale obiettivo una più efficace e completa ricostruzione dell’antica comunità pitecusana, e di cui, in questa sede, si illustrano le procedure analitiche e i risultati preliminari
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

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
morphomap: An R package for long bone landmarking, cortical thickness, and cross-sectional geometry mapping
Full text linkObjectives: This study describes and demonstrates the functionalities and application of a new R package, morphomap, designed to extract shape information as semilandmarks in multiple sections, build cortical thickness maps, and calculate biomechanical parameters on long bones. Methods: morphomap creates, from a single input (an oriented 3D mesh representing the long bone surface), multiple evenly spaced virtual sections. morphomap then directly and rapidly computes morphometric and biomechanical parameters on each of these sections. The R package comprises three modules: (a) to place semilandmarks on the inner and outer outlines of each section, (b) to extract cortical thicknesses for 2D and 3D morphometric mapping, and (c) to compute cross-sectional geometry. Results: In this article, we apply morphomap to femora from Homo sapiens and Pan troglodytes to demonstrate its utility and show its typical outputs. morphomap greatly facilitates rapid analysis and functional interpretation of long bone form and should prove a valuable addition to the osteoarcheological analysis software toolkit. Conclusions: Long bone loading history is commonly retrodicted by calculating biomechanical parameters such as area moments of inertia, analyzing external shape and measuring cortical thickness. morphomap is a software written in the open source R environment, it integrates the main methodological approaches (geometric morphometrics, cortical morphometric maps, and cross-sectional geometry) used to parametrize long bones
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
