Regional Farmers’ Perception and Societal Issues in Vineyards Affected by High Erosion Rates

2021

We explore the current situation in a viticultural region in Eastern Spain from a holistic and multifaceted research approach, which allowed us to understand the biophysical conditions, economic cost, social impact, and perception of the farmers’ community to the use of catch crops. A survey of the perception of the farmers, and an assessment of the biophysical impact of catch crops (CC) and tillage (C = Control plot) on soil organic matter, bulk density, infiltration capacity (single ring infiltrometer), and runoff generation and soil erosion (rainfall simulation experiments) was carried out. Two representative fields as study sites were selected in Les Alcusses valley, within Els Alforins…

Vocational teachers' professional agency in the stream of change

“Voz del alumnado”: hacer de los estudiantes participantes activos y responsables en los procesos formativos activados en la escuela y en la universi…

2017

"Voce degli studenti" è un movimento pedagogico nato negli anni novanta in alcuni paesi di lingua inglese (Stati Uniti, Canada, Inghilterra e Australia). Supporta la partecipazione attiva e responsabile degli studenti ai processi di formazione attivati nella scuola e nell'università. Per includere le voci degli studenti in questi processi, gli adulti (insegnanti e amministratori) devono riconoscere i loro diritti di essere ascoltati e rispettati come persone con interessi, bisogni di apprendimento e idee che possono risolvere i problemi della didattica scolastica/universitaria, della ricerca educativa e delle politiche culturali in cui si devono prendere decisioni che li riguardano. In ques…

A Low-Cost Smartphone Sensor-Based UV Camera for Volcanic SO2 Emission Measurements

2017

Recently, we reported on the development of low-cost ultraviolet (UV) cameras, based on the modification of sensors designed for the smartphone market. These units are built around modified Raspberry Pi cameras (PiCams; ≈USD 25), and usable system sensitivity was demonstrated in the UVA and UVB spectral regions, of relevance to a number of application areas. Here, we report on the first deployment of PiCam devices in one such field: UV remote sensing of sulphur dioxide emissions from volcanoes; such data provide important insights into magmatic processes and are applied in hazard assessments. In particular, we report on field trials on Mt. Etna, where the utility of these devices in quantif…

Lidar detection of carbon dioxide in volcanic plumes

2015

Volcanic gases give information on magmatic processes. In particular, anomalous releases of carbon dioxide precede volcanic eruptions. Up to now, this gas has been measured in volcanic plumes with conventional measurements that imply the severe risks of local sampling and can last many hours. For these reasons and for the great advantages of laser sensing, the thorough development of volcanic lidar has been undertaken at the Diagnostics and Metrology Laboratory (UTAPRAD-DIM) of the Italian National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA). In fact, lidar profiling allows one to scan remotely volcanic plumes in a fast and continuous way, and with high s…

Electrochemical sensor for phosphate ions based on laser scriber reduced graphene oxide

2022

This preliminary work shows a new and innovative way to produce laser scribed reduced graphene oxide (LSGO) electrodes using different porous substrates (ranging from paper to plastic and fabric). The obtained electrodes were also tested as electrochemical sensors towards the detection of phosphate ions in water. To obtain the electrodes, a water suspension of GO was filtered on top of substrate (such as Whatman® filter paper) and a complete sensor was obtained from its reduction using a CO2 laser. The electrode is composed of working and counter electrodes made of LSGO and a reference electrode of a Ag/AgCl obtained by using a commercial AgCl conductive paste. Phosphate ions were detected …

Citizen Response in Crisis : Individual and Collective Efforts to Enchance Community Resilience

2014

This paper reports on the process and findings of an extensive research project with the aim of investigating present initiatives and approaches within the area of community resilience and citizen involvement. The paper specifically addresses which emerging sociotechnical approaches can be discerned within these initiatives. The discussion is structured within three categories of potential voluntary engagement; organized volunteers, semiorganized individuals, and “nonorganized” individuals. The empirical material assembled in the research project is contrasted with contemporary international research literature regarding sociotechnical means for enhancing community resilience. Swedish appro…

De la perception de la voyelle /y/ chez des apprenants polonais du français langue étrangère

2019

International audience; The main objective of this study is to test the perception of the vowel /y/ among the Polish learners of FLE, as it does not exist in their natural vowel system. We defend the hypothesis that optimal perception conditions can make the identification and acquisition of new sounds more intelligible.; L'objectif principal de cette étude est de tester la perception de la voyelle /y/ chez des apprenants polonais du FLE, celle-ci n'existant pas, en effet, dans leur système vocalique naturel. Nous défendons l'hypothèse selon laquelle des conditions de perception optimales peuvent rendre plus nettes, plus intelligibles, la perception et l'acquisition de sons nouveaux.

Ontology and protocol secure for SCADA

2014

In this work, we present a semantic cyber security system and we study its semantic intelligent systems vulnerabilities, focusing on the semantic attacks. For resolving semantic problems we propose a security global solution for the new generation of SCADA systems. The proposed solution aims at protecting critical semantic SCADA processes from the effects of major failures and semantic vulnerabilities in the modern IT-SCADA network. We used a security block in the global network access point, security protocols deployed in different network (OSI) levels and security ontologies deployed in security devices. We used our mixed coordinates (ECC) cryptography solution, this is an encryption tech…

Empathy, Entrainment, and Perceived Interaction in Complex Dyadic Dance Movement

2019

The current study explores how individuals' tendency to empathize with others (trait empathy) modulates interaction and social entrainment in dyadic dance in a free movement context using perceptual and computationally derived measures. Stimuli consisting of 24 point-light animations were created using motion capture data selected from a sample of 99 dyads, based on self-reported trait empathy. Individuals whose Empathy Quotient (EQ) scores were in the top or bottom quartile of all scores were considered to have high or low empathy, respectively, and twelve dyads comprised of four high-high, four low-low, and four high-low empathy combinations were identified. Animations of these dyads were…
