Baracche, un site épigravettien récent dans la Dorsale de Cingoli, Marches.
No full textDans ce travail sont présentés les résultats de l'étude d’une collection lithique provenant d’un niveau épigravettien daté à 15ka 14C BP, correspondant à une occupation en plein-air située sur une terrasse alluviale au pied de la dorsale des Cingoli. Le matériel, issu d’une récolte effectuée sur le front d’une ancienne carrière, présente des caractères homogènes et un état de conservation qui justifient une étude plus détaillée. Les caractères litho-technologiques, la structure ainsi que les remontages par unités de matière première lithique, suggèrent la présence soit d’une aire d’atelier de production, soit de rejet des sous-produits du débitage
Baracche, un nuovo sito epigravettiano nella Valle del Rio Láque (Cingoli).
No full textScoperto nel 1998 sul fronte di una cava per inerti, il sito di Baracche presenta un unico livello archeologico con manufatti litici ascrivibili a procedimenti di scheggiatura laminare e lamellare. Alcune caratteristiche tecnologiche e l’unica punta a dorso rinvenuta forniscono un inquadramento del sito all’Epigravettiano Recente. Numerosi rimontaggi sottolineano le ottime condizioni di conservazione del record archeologico, gettando le basi per uno scavo sistematico in futuro

UV-Curable SiO2–TiO2 Films for the Realization of Diffractive Optical Elements
No full textHybrid SiO(2)-TiO(2) films are prepared starting from tetraisopropoxy titanate and 3-glycidoxipropyltrimethoxysilane, using the sol-gel process. During the sol synthesis titania clusters grow, conferring to the samples a photocatalytic activity. In this paper we exploit this property for the fabrication of surface-relief gratings. The realized structures are characterized by SEM, AFM and profilometric measurements, while the presence of titania clusters is confirmed by TEM analyses

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
