Stratigraphic Excavation from the Field to the Computer: The Pompeii Prototipe
No full textThis work is included in the MURST - COFIN 1998 project under the responsibility of Prof. A. Carandini, University of Roma “La Sapienza”, Italy. The principal aim of this project is to develop a computer assisted method that could help in excavation management and support Stratigraphic Unit (SU) forms with as much information as possible. Our work intends to give a 3D visualisation of the excavation broken down into its elements: Stratigraphical Units. We want to complete the usual graphical documentation (plans and prospects) with a format showing surfaces and volumes of SUs excavated. We decided to test this prototype in a room of a Pompeian domus (Casa della Pescatrice) excavated in the year 2000 investigation by the University of Rome “La Sapienza”. As a SU was located, a picture was taken using a Nikon Reflex digital camera. Every shot also includes 4 small targets outside the SU in order to allow the orthorectification and joining with the 3D model. Secondly we surveyed the targets, the border and the internal surface of the SU using an ETS. The internal surface was surveyed at a rate of 100 points per square meter, but in the case of rugged surfaces we went down to 400 points per square meter. Only two persons (one using the ETS, the other keeping the prism) were engaged in these operations, carried out every time our colleagues decided to remove a SU. We do not believe this kind of work retards normal field operations and at the same time does not waste energy. Topographical data were successively transferred from the ETS memory card to a Personal Computer and then processed with the same software used for the management of the entire project: ESRI ArcView. We interpolated our points in order to make our surface as detailed as possible using ArcView 3D Analyst extension. The next step was to orthorectificate the images of every single SU and to insert them as themes in the same ArcView project. The resulting surface could be oriented as much as desiredon every one of the 3D axes, allowing unlimited different views of the same SU. We want to emphasise that any of these operations requires neither complicated Information Technology (IT) skills nor weeks spent in processing data: on the contrary, each of them can be carried out in a short time. Another important point is that the SU presented are in a format that bases itself on the data taken with a very accurate instrument that reduces enormously the errors resulting from manual plotting operations
Monte Tabor. Contesti storici e topografici
No full textIl lavoro presenta i risultati di una ricerca indirizzata verso si seguenti obiettivi : 1) definire le fasi storiche e le configurazioni
topografiche dell’area geografica nel quale si inquadra il contesto Monte Tabor; 2) realizzare una serie di piante di fase che, a scala ancora ampia (l’intera area della Palestina antica), possano presentare una prima ricostruzione degli assetti storico-geografici nella
regione, dalla creazione dei regni ellenistici (fine del III secolo a.C.) all’età Tardo Antica (V secolo d.C.)
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
