Il mondo orafo fra tradizione e innovazione
No full textIl mondo orafo è costituito da una moltitudine di PMI. in questa fase di intenso cambiamento, numerose sono le scelte che esse si trovano a dover operare e molti i quesiti che necessitano una risposta. Occorre capire ad esempio se la crescita dimensionale rappresenti una strada obbligata per le aziende del settore; se siano necessari nuovi assetti manageriali; quali siano le attività alla base della creazione di prodotti di successo; quali strategie per internazionalizzarsi e gestire la distribuzione. Il libro propone un percorso interpretativo rispetto a queste problematiche e offre spunti affinché ciascuna azienda possa individuare una propria via di consolidamento e sviluppo

DTM cross validation and merging: problems and solutions for a case study whithin the Heli-DEM project
No full textAlmost all official national cartographic bases in Europe include Digital Terrain Models (DTMs). To perform analyses at the borders
between countries, transnational geographic information is needed: a transnational DTM can be obtained by merging regional DTMs
(usually at low resolution) and other typically local high resolution DTMs. To be used the different DTMs must be in the same three
dimensional reference frame, they must not present biases and must be consistent at the nominal scale. The following preliminary
actions are required:
• 3D reference frame transformation of gridded data,
• cross-validation of the regional DTMs,
• cross-check of the regional LR DTMs and the local HR DTMs.
The paper discusses the study, the implementation and the application of algorithms to solve these problems in the Alpine area
between Italy and Switzerland. For this case study, the regional DTMs of Lombardy, Piedmont and Switzerland, respectively with a
planimetric resolution of 20, 50 and 25 meters are available. In addition, a LiDAR DTM with a planimetric resolution of 1 meter for
the Lombardy and Piedmont hydrographic basins is available. The different DTMs have been transformed to the same reference
frame by applying the official national 3D transformations. The cross-validation and the cross-check of the elevation datasets have
been performed. All these operations have required the implementation of novel approaches to interpolate and compare DTMs and to
spatially analyze their differences
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
