Permanent Stations for Calibration/Validation of Thermal Sensors over Spain
2016
The Global Change Unit (GCU) at the University of Valencia has been involved in several calibration/validation (cal/val) activities carried out in dedicated field campaigns organized by ESA and other organisms. However, permanent stations are required in order to ensure a long-term and continuous calibration of on-orbit sensors. In the framework of the CEOS-Spain project, the GCU has managed the set-up and launch of experimental sites in Spain for the calibration of thermal infrared sensors and the validation of Land Surface Temperature (LST) products derived from those data. Currently, three sites have been identified and equipped: the agricultural area of Barrax (39.05 N, 2.1 W), the mars…
Brancati su Pirandello e il pirandellismo
2019
Nel romanzo breve "Sogno di un valzer" uscito a puntate su “Quadrivio”, dal 5 giugno al 14 agosto 1938, Vitaliano Brancati mette in scena, tra osservazione dei luoghi e rilevamento di costume, un’umanità fuori misura, continuamente in bilico tra realtà e sogno. A Caltanissetta (Nissa) la città nel cui Istituto magistrale lo scrittore, voltate le spalle alla Roma fascista, è venuto a insegnare, personaggi non appariscenti, insignificanti, che tuttavia covano desideri, si arrovellano in domande metafisiche. Prende così forma il leitmotiv delle critica al pirandellismo che più volte con ironia sottile affiora negli scritti brancatiani. Il saggio mostra come esso si intrecci con la comicità sul…
Modelling of piping collapses and gully headcut landforms: Evaluating topographic variables from different types of DEM
2021
Abstract The geomorphic studies are extremely dependent on the quality and spatial resolution of digital elevation model (DEM) data. The unique terrain characteristics of a particular landscape are derived from DEM, which are responsible for initiation and development of ephemeral gullies. As the topographic features of an area significantly influences on the erosive power of the water flow, it is an important task the extraction of terrain features from DEM to properly research gully erosion. Alongside, topography is highly correlated with other geo-environmental factors i.e. geology, climate, soil types, vegetation density and floristic composition, runoff generation, which ultimately inf…
Funzionalità di uno strumento di osservazione per progettare interventi educativi
2023
Il contributo presenta una guida di osservazione costruita secondo l’International Classification of Functioning, Disability and Health (ICF, 2001; 2007), per la conferma o modifica del Profilo di Funzionamento degli alunni di scuola primaria in situazione di disabilità e per la formulazione del relativo Piano Educativo Individualizzato (PEI) da parte degli insegnanti. La guida per l’insegnante è stata preparata partendo da alcuni recenti strumenti di osservazione. È stata effettuata una prima validazione dello strumento su un campione di insegnanti di scuola primaria (n=611); i risultati delle analisi mostrano una buona validità di costrutto rispetto ai domini di contenuto dell’ICF e ai re…

Distribution of Working Time and Contents of Physiotherapy Activities in a Clinical Setting.
1994
The purpose of the present study was to collect personnel utilization data in the physiotherapy department of a general hospital as a basis for improving the practice of physiotherapy. Over a four-week period in a process of continuous observation 12 physiotherapists recorded their activities under predefined task categories. The percentages of total time used in the observed activities were as follows: direct patient treatment 31%, other work (planning, recording, arranging walking aids and student guidance) 10%, and cooperation (consultation, meetings, arranging patients' affairs, counselling relatives and parents) 9%. The proportion of uncategorized work amounted to half of the total wor…
Continuous SO2 flux measurements for Vulcano Island, Italy
2012
<p>The La Fossa cone of Vulcano Island (Aeolian Archipelago, Italy) is a closed conduit volcano. Today, Vulcano Island is characterized by sulfataric activity, with a large fumarolic field that is mainly located in the summit area. A scanning differential optical absorption spectroscopy instrument designed by the Optical Sensing Group of Chalmers University of Technology in Göteborg, Sweden, was installed in the framework of the European project "Network for Observation of Volcanic and Atmospheric Change", in March 2008. This study presents the first dataset of SO<sub>2</sub> plume fluxes recorded for a closed volcanic system. Between 2008 and 2010, the SO<sub>2</…
Aviation Contrail Cirrus and Radiative Forcing Over Europe During 6 Months of COVID‐19
2021
Abstract The COVID‐19 pandemic led to a 72% reduction of air traffic over Europe in March–August 2020 compared to 2019. Modeled contrail cover declined similarly, and computed mean instantaneous radiative contrail forcing dropped regionally by up to 0.7 W m−2. Here, model predictions of cirrus optical thickness and the top‐of‐atmosphere outgoing longwave and reflected shortwave irradiances are tested by comparison to Meteosat‐SEVIRI‐derived data. The agreement between observations and modeled data is slightly better when modeled contrail cirrus contributions are included. The spatial distributions and diurnal cycles of the differences in these data between 2019 and 2020 are partially caused…
Autism spectrum disorders in children affected by Duchenne muscular dystrophy
2018
Background Duchenne muscular dystrophy (DMD) is the most frequent and severe form of the dystrophinopathies. The literature shows that about 30-40% of DMD subjects have intellectual disability. In males with Duchenne muscular dystrophy, neuropsychiatric disorders have also been observed: attention deficit disorder and hyperactivity, autism spectrum disorders, and obsessive-compulsive disorder. Duchenne muscular dystrophy is not just a muscle disorder, but also a disease that affects the brain. The aim of the present study was to describe a case series of children with Duchenne muscular dystrophy that have also the presence of autism spectrum disorders (ASDs). They have been assessed by mean…
An analysis of the different patterns of 1:1 interactions between educational professionals and their students with varying abilities in inclusive cl…
2012
The purpose of this study was to examine the different types and patterns of 1:1 interactions provided by general educators, special educators and paraprofessionals to children with mild disabilities (n = 13), severe disabilities (n = 13), and children without disabilities (n = 13) in inclusive classrooms. General educators, special educators, and paraprofessionals' 1:1 interactions with students in three comparison groups were recorded in 17 elementary and middle school classrooms using a partial interval observation system. We found significant differences with respect to interaction frequency and content. Teachers and paraprofessionals had consistently more 1:1 interactions with students…
