Viaggi nell’immaginario: il turismo virtuale nel sito UNESCO di Tarragona
2023
Le nuove tecnologie hanno trasformato in modo radicale non solo la geografia come disciplina, ma anche le geografie del mondo. Il digitale ha assunto, infatti, un ruolo di mediazione sempre più pervasivo nella produzione dello spazio, come delle conoscenze e degli immaginari geografici. Le possibilità offerte dal virtuale, in particolare, offrono oggi un contributo decisivo nella comunicazione dei significati attribuiti ai luoghi e rispondono in modo sempre più efficace ai bisogni emergenti del settore turistico. Le esperienze di visita mediate dal digitale mirano a coinvolgere i sensi e risultano efficaci quando promuovono immersioni rigorosamente realistiche. Nel quadro di queste riflessi…
On a new robust workflow for the statistical and spatial analysis of fracture data collected with scanlines (or the importance of stationarity)
2020
Abstract. We present an innovative workflow for the statistical analysis of fracture data collected along scanlines, composed of two major stages, each one with alternative options. A prerequisite in our analysis is the assessment of stationarity of the dataset, which is motivated by statistical and geological considerations. Calculating statistics on non-stationary data can be statistically meaningless, and moreover the normalization and/or sub-setting approach that we discuss here can greatly improve our understanding of geological deformation processes. Our methodology is based on performing non-parametric statistical tests, which allow detecting important features of the spatial distrib…
A Time Projection Chamber with GEM-Based Readout
2016
For the International Large Detector concept at the planned International Linear Collider, the use of time projection chambers (TPC) with micro-pattern gas detector readout as the main tracking detector is investigated. In this paper, results from a prototype TPC, placed in a 1 T solenoidal field and read out with three independent GEM-based readout modules, are reported. The TPC was exposed to a 6 GeV electron beam at the DESY II synchrotron. The efficiency for reconstructing hits, the measurement of the drift velocity, the space point resolution and the control of field inhomogeneities are presented.
A CZT 3D imaging spectrometer prototype with digital readout for high energy astronomy
2023
The scientific challenges still open in hard X-rays and γ-rays astronomy require the development of new instrumentation able to overcome the sensitivity limits of the present one. Among the technologies currently under study to cover the energy range between several tens of keV and one MeV, the development of telescopes equipped with broadband Laue lenses associated with focal planes with high spectroscopic and imaging performance represents an extremely promising solution. With this perspective, we report on the development and the first spectroscopic characterisation results of an X/γ rays detection system (10-1000 keV) based on CZT spectrometers with spatial resolution in three dimension…
Types of climates on continental France, a spatial construction
2010
Le climat est un élément important de la vie des territoires car il conditionne le comportement et les décisions des individus et des groupes sociaux comme celui de l’ensemble des espèces vivantes et des écosystèmes. A ce titre, la différenciation de l’espace selon les climats et les aptitudes qui en résultent est un domaine qui mérite d’être réinvesti par la recherche en mettant à profit des moyens de traitement modernes de l’information. Avec cet objectif en vue, les auteurs proposent une approche spatiale de définition des climats. Partant des mesures stationnelles de précipitation et de température mises à disposition par Météo-France, un jeu de 14 variables intégrant une série temporel…
Sistemi di orientamento nel latino di Plauto
2021
This paper investigates the spatial Frames of Reference (FoRs) in Old Latin within the framework of cognitive linguistics. Differently from modern romance languages, which are heavily based on the so-called relative FoR, ancient Indo-European languages such as Vedic and Homeric Greek did not make use of such an egocentric orientation system at their earliest stage, since the relation between FIGURE and GROUND was not specified by imposing an external deictic observer’s viewpoint. the aim of this study is to add the perspective of Old Latin, by focusing on the contexts of use of spatial terms of FRONT, BEHIND, LEFT, RIGHT in the comedies of Plautus. The results of this analysis are consisten…
The role of experience in work and learning among design engineers
2004
Taking an approach to learning in the workplace as a phenomenon situated and accumulated in the course of work activities and everyday practice, the purpose of this study was to investigate how workers (development engineers and designers) themselves perceive the role of experience in work and learning. The empirical material consists of interviews with 18 employees in two enterprises in Finland. Narrative analysis of the holistic core stories yielded four thematic categories. The categories indicate that learning from experience plays an essential part in coping and learning along with other people, in understanding holistic work processes and in creating a personal perception of one’s wor…
Stone lines and heaps on south-western Niger plateaus as remains of ancient agricultural land
2011
Les plateaux de la rive occidentale du fleuve Niger sont recouverts de lignes et de tas de pierres sèches alors que ces surfaces tabulaires sont aujourd'hui dépourvues de toutes cultures. Le sol du plateau est constitué d'un horizon argilo-sableux visible uniquement dans la zone où ces structures sont présentes. Elles témoigneraient d'un épierrage pour faciliter le travail agricole du sol. Les matériaux extraits ont été disposés en ligne puis en tas si la quantité de blocs était trop élevée. Ce parcellaire pourrait être contemporain de l'activité métallurgique située au pied des plateaux et datée de la deuxième moitié du premier millénaire.
Place-based attributes and spatial expenditure behavior in tourism
2017
In recent discussions on local sustainable development, notions like “local for local” and “home bias” have often played a role. The purpose of this paper is to investigate whether preferences for specific place-based attributes might constrain or support tourism participation and tourism destination choice of distinct socioeconomic groups of visitors. To test this proposition, a large data set from the Italian Households Budget Survey for the period 1997–2007 has been used and, by means of the double-hurdle model, tourism participation and expenditure are modeled over the life-cycle of tourists. These data are next merged with location-specific attributes including natural amenities and in…
