Paleontología y ambientes sedimentarios del triásico medio, Muschelkalk, de la cordillera ibérica I : Cuenca y Valencia, España
1989
Las unidades dolomías de Landete (d. L.), areniscas, margas y yesos del Mas (a.m.y.M.) y dolomías y calizas de Cañete (d.c.C.) (Anisiense-parte inferior del Camiense, Triásico mediosuperior) de base a tecbo respectivamente, constituyen la Facies Muscbelkalk al SE. de la Rama Castel1ana de la Cordil1era Ibérica. Este trabajo enfoca el estudio paleontológico y de los medios sedimentarios de las dos unidades carbonatadas (d.L. y d.c.C.). Para el1o, se ban utilizado 10 columnas estratigráficas a lo largo de todo el área de estudio en las cuales se ban diferenciado 9 asociaciones de facies constituidas cada una por una secuencia característica de menos de 2 m. de espesor. Se ba escogido una seri…
Paleontología y ambientes del Triásico Medio en el sector noroccidental de la cordillera ibérica (provs. de Soria y Guadalajara, España)
1991
El Triásico Medio del sector noroccidental de la Cordillera Ibérica está compuesto por dos formaciones carbonáticas, que se corresponden con la unidad carbonática superior del Muschelkalk, y que hacia el NW pasan lateralmente a una formación terrígena. El registro fósil se encuentra en ambos tipos de formaciones. Tanto el estudio tafonómico como sedimentológico, permiten inferir la presencia de elementos acumulados que podrían corresponder a asociaciones autóctonas, compuestas en su mayoría por bivalvos infaunales de medios marinos someros y sometidos a fuerte influencia de terrígenos. Se caracterizan en la zona tres asociaciones faunísticas: 1. Asociación CostatoriaLyriomyophoria, que apar…
Technical efficiency and regional disparities in Italy
2019
This paper is a contribution to the literature on Italy's regional disparities with a focus on the nature and determinants of firms' technical efficiency. Our analysis concerns a vast number of Italian firms for the decade 2008-2017 and considers the firms that are annually obliged to deposit their balance sheet. A frontier stochastic analysis is used as a method for estimating the technical efficiency of each firm. Our results offer a detailed representation on a provincial basis of disparity gaps. Moreover econometric analysis provides convincing evidence on the importance of territorial variables in the determinants of technical efficiency.
Smart cities: a policy tool for city efficiency?
2016
The level of interest in smart cities has been growing during these last years. The academic literature (Hollands, 2008; Caragliu et al., 2009, Nijkamp et al., 2011 and Lombardi et al., 2012) has identified a number of factors that characterise a city as smart, such as economic development, business-friendly, environmental sustainability, social innovation, information and knowledge process, and human and social capital. Thus, the smartness concept is strictly linked to urban efficiency in a multifaceted way as well as to citizens’ wellbeing through the use of appropriate technologies. Instead, from a “political perspective” smartness is mainly related to the ability of using ICT as instrum…
Crowdfunding civico: finanziamento dal basso per uno sviluppo urbano condiviso
2014
La crisi economica internazionale ha determinato la riorganizzazione e il riequilibrio complessivo di dinamiche e pratiche di gestione urbana e territoriale. Attori coinvolti, ruoli, strumenti giuridici ed economici alternativi a quelli tradizionali sono gli elementi basilari di tali trasformazioni. La partecipazione pubblica al processo di pianificazione può assumere nuove forme, come quella rappresentata dal crowdfunding civico: si tratta di un meccanismo di finanziamento collettivo, reso innovativo dal fatto che viene realizzato attraverso un’apposita piattaforma web. In questo modo viene garantita la trasparenza dell’operazione e le quote versate possono essere restituite se non si ragg…

Land surface temperature retrieval from LANDSAT TM 5
2004
In this paper, three methods to retrieve the land surface temperature (LST) from thermal infrared data supplied by band 6 of the Thematic Mapper (TM) sensor onboard the Landsat 5 satellite are compared. The first of them lies on the estimation of the land surface temperature from the radiative transfer equation using in situ radiosounding data. The others two are the mono-window algorithm developed by Qin et al. [International Journal of Remote Sensing 22 (2001) 3719] and the single-channel algorithm developed by Jime´nez-Mun˜oz and Sobrino [Journal of Geophysical Research 108 (2003)]. The land surface emissivity (LSE) values needed in order to apply these methods have been estimated from a…
