Economia: parole concetti narrazioni (secoli XVI-XVIII)
2019
Con un’innovativa impostazione metodologica ed epistemologica, che coniuga la distinzione fra semasiologia e onomasiologia con il concetto di storia come storia contemporanea, l’Autore ricostruisce l’evoluzione del termine-concetto ‘economia’ nella prima età moderna, facendo costante riferimento alle narrazioni prodotte durante l’età classica. A partire dalla parola greca oikonomia e dal concetto di ‘legge della Casa’, ‘amministrazione della famiglia’, il libro ripercorre il processo attraverso il quale fra Medioevo ed età contemporanea questa parola e questo concetto furono rimeditati e trasformati, aprendo la strada al moderno concetto di economia. Un ruolo fondamentale in questo processo…
Automated Detection of Microaneurysms Using Scale-Adapted Blob Analysis and Semi-Supervised Learning
2014
International audience; Despite several attempts, automated detection of microaneurysm (MA) from digital fundus images still remains to be an open issue. This is due to the subtle nature of MAs against the surrounding tissues. In this paper, the microaneurysm detection problem is modeled as finding interest regions or blobs from an image and an automatic local-scale selection technique is presented. Several scale-adapted region descriptors are then introduced to characterize these blob regions. A semi-supervised based learning approach, which requires few manually annotated learning examples, is also proposed to train a classifier to detect true MAs. The developed system is built using only…
Il Grande Cretto di Gibellina
2022
The essay aims to make explicit the methodological criteria underlying the semiotic analysis of a space, taking as an example the case of the Grande Cretto that Alberto Burri realised in Gibellina in the second half of the 1980s. An impressive Land Art work that presents at first sight a series of clear-cut oppositions, but which on closer inspection calls them into question, rather emphasising gradations and nuances. The essay considers the discourses of space and those on space, the levels of the generative path, the plastic and figurative languages, showing how the analysis is the outcome of a continuous adjustment between the researcher and the text: the former engaged in constructing a…
Variazioni di carbonio organico nei suoli italiani dal 1979 al 2008
2010
I suoli contengono circa tre volte la quantità di carbonio disponibile a livello mondiale nella vegetazione e circa il doppio di quella presente in atmosfera. Tuttavia il carbonio organico del suolo (SOC) si è ridotto in molte aree, mentre è stato rilevato un aumento della CO2 atmosferica. Ricerche recenti hanno dimostrato che sono stati i cambiamenti di uso e gestione del suolo a provocare le maggiori perdite di SOC nel recente passato, piuttosto che le più alte temperature e i cambiamenti delle precipitazioni conseguenti il cambiamento climatico. Lo scopo principale di questo lavoro è quello di stimare le variazioni del contenuto di carbonio organico dei suoli (carbon stock, CS) in Italia…
Looking ahead in games research
2021
This thematic issue presents a number of emerging scholarships into the study of digital gaming. The articles are based on a 2019 symposium on game studies hosted by the Digital Games Research section of ECREA. As the phenomena related to digital gaming keep on evolving and emerging, so must research keep up with the times and constantly challenge itself. Whether speaking about validating previously developed research methods, imagining totally new ones, or even challenging the whole philosophy of science on which research is being done, there is a constant need for reappraisal and introspection within games research. As a cultural medium that has become deeply embedded into the social fabr…

Shadowing e GIS qualitativo: due strumenti per narrare la città
2015
Questo breve articolo descrive la città attraverso due tecniche di ricerca qualitativa (lo shadowing e il GIS qualitativo). Partendo da alcuni esempi, tratti dall’esperienza sul campo, vengono valutati limiti e possibilità delle tecniche in oggetto. L’obiettivo è quello di argomentare la necessità di utilizzare e sviluppare nuovi strumenti metodologici per conoscere le configurazioni urbane. Gli autori sostengono il bisogno di muoversi all’interno di un orizzonte interdisciplinare e di utilizzare tecniche capaci di far emergere narrazioni polifoniche della città. Analizzando le potenzialità dialogiche dello shadowing e le potenzialità sovversive dei GIS qualitativi, una cartografia capace d…
Limits to Arbitrage and Interest Rates: a Debate Between Keynes, Hawtrey and Hicks
2018
International audience; This paper deals with a debate between Hawtrey, Hicks and Keynes concerning the capacity of the central bank to influence the short-term and the long-term rates of interest. Both Hawtrey and Keynes considered the central bank’s ability to influence short-term rates of interest. However, they do not put the same emphasis on the study of the long-term rates of interest. According to Keynes, long-term rates are influenced by future expected short-term rates (1930, 1936), whereas for Hawtrey (1932, 1937, 1938), long-term rates are more dependent on the business cycle. Short-term rates do not have much effect on long-term rates according to Hawtrey. In 1939, Hicks enters …
Aplicación del sistema de informacion arqueológica SIDGEIPA a la gestión de la excavación de urgencia del yacimiento la Colata (Montavener, Valencia)
2003
La aplicación del programa Sidgeipa en la excavación de urgencia realizada en el yacimiento de La Colata (Montaverner, Valencia), ha permitido documentar de forma rápida y fiable, casi un centenar de estructuras negativas, de diversa tipología y atribución cronológica. Una de las características más eficaces de Sidgeipa reside en su capacidad para almacenar, de forma razonable, la gran cantidad de datos generados en la excavación, las coordenadas tridimensionales de todas las estructuras registradas, los materiales hallados en el interior de sus rellenos (incluidos los individuos enterrados) y toda la información correspondiente a las Unidades Estratigráficas que hayan sido distinguidas. La…
A Multi-Projector Calibration Method for Virtual Reality Simulators with Analytically Defined Screens
2017
The geometric calibration of projectors is a demanding task, particularly for the industry of virtual reality simulators. Different methods have been developed during the last decades to retrieve the intrinsic and extrinsic parameters of projectors, most of them being based on planar homographies and some requiring an extended calibration process. The aim of our research work is to design a fast and user-friendly method to provide multi-projector calibration on analytically defined screens, where a sample is shown for a virtual reality Formula 1 simulator that has a cylindrical screen. The proposed method results from the combination of surveying, photogrammetry and image processing approac…
