SELVICOLTURA ALPINA E SELVICOLTURA APPENNINICA: ELEMENTI DI CONTATTO E DI DIFFERENZIAZIONE
2009
Riassunto Il rapporto tra boschi e popolazioni locali sulle Alpi come sugli Appennini, seppur in momenti storici differenti, è stato caratterizzato dalla distruzione e sfruttamento intensivo, protrattisi fino alla metà del secolo scorso, cui hanno fatto seguito la ricostituzione sia mediante rimboschimenti sia con il miglioramento dei boschi esistenti. Partendo dai presupposti sui quali si è imperniata l’attività forestale che ha caratterizzato, nel corso degli ultimi cinquant’anni, l’approccio selvicolturale nei due contesti e da una puntuale e documentata analisi, nel lavoro vengono evidenziati gli elementi di differenziazione tra la selvicoltura naturalistica applicata in ambiente alpino…
La biodiversità dei boschi siciliani. Parte I: l’avifauna
2014
È stata censita la diversità delle specie ornitiche presente in alcune tipologie forestali della Regione Siciliana e la relazione tra le ornitocenosi, le scelte gestionali ed i diversi fattori abiotici e biotici. L’analisi della species richness (= numero delle specie) dimostra che essa è correlata con il bioclima, il diametro massimo degli individui arborei, il valore trofico di tutti gli strati di vegetazione ed il valore trofico dello strato arboreo. I boschi meso-supramediterranei sono più ricchi di specie rispetto ai boschi termomesomediterranei. L’importanza del diametro massimo degli individui arborei, che esprime indirettamente anche il tipo di gestione di un bosco, viene spiegata d…
Cognitive Computing supported Medical Decision Support System for Patient’s Driving Assessment
2018
To smartly utilize a huge and constantly growing volume of data, improve productivity and increase competitiveness in various fields of life; human requires decision making support systems that efficiently process and analyze the data, and, as a result, significantly speed up the process. Similarly to all other areas of human life, healthcare domain also is lacking Artificial Intelligence (AI) based solution. A number of supervised and unsupervised Machine Learning and Data Mining techniques exist to help us to deal with structured data. However, in a real life, we pretty much deal with unstructured data that hides useful knowledge and valuable information inside human-readable plain texts,…
Grassland fire effect on soil organic carbon reservoirs in semiarid environment.
2011
The effect of fire on soil organic matter content is highly variable and depends on several factors including fire intensity, soil type and nature of burned material. Grassland in semiarid environment are often managed by shepherds with annual burning in order to enhance pasture recovery. The aim of this work was investigating the effect of fire as grassland management tool on soil organic carbon (SOC) reservoirs and on post-fire plant recovery. The study was conducted on Hyparrenia hirta grassland and Ampelodesma mauritanicus grassland, located in the Province of Palermo, in the north of Sicily. Soil samples were collected at two depth (0-5 and 5-20 cm) before and after experimental fire a…
Academic performance in terms of the applied assessment system
2012
This paper examines the academic performance depending on the evaluation and rating system used in the university. The sample under study consists of 30 subjects -taught by 35 professors to 2192 students from 7 different degrees at 14 universities of all Spain-. The results confirm that continuous assessment is the one that best results not only in terms of rate of return and success rate but also in terms of grades. En este trabajo se estudia el rendimiento académico en función del sistema de evaluación y calificación empleado en el ámbito universitario. La muestra objeto de estudio está formada por 30 asignaturas -impartidas por 35 profesores a 2192 alumnos de 7 titulaciones diferentes en…

Evaluation and Self-Evaluation in Simultaneous Translation: Assessments Methods
2012
Abstract The nature of evaluation and self-evaluation in simultaneous interpretation is based on the close connection between the main text (the version proposed by the speaker) and the interpreter's version. Between these two elements a number of variables emerge, that can damage the efficiency and the accuracy of simultaneous interpretation. The intention of our study is to propose a set of scientific methods and tools in order to offer to the interpreter the possibility of a self-assessment and the benefit of an appropriate evaluation of his work. In order to achieve these goals we used several methods, including experiments, case studies, questionnaires, evaluation scales. Research subj…
Revista electrónica de investigación y evaluación educativa
2016
El Programa para la Evaluación Internacional de Alumnos (PISA) proporciona un marco en el que más de 80 países colaboran para construir métricas globales avanzadas para explorar los conocimientos, habilidades y atributos del estudiantado. El diseño de las evaluaciones plantea importantes desafíos conceptuales y técnicos, como el éxito del aprendizaje. Más allá de una base conceptual sólida, PISA necesita cumplir una serie de exigencias a veces contradictorios. Los/as administradores de escuelas, autoridades normativas y los docentes deben ser capaces de utilizar esta información de la evaluación para determinar cómo crear mejores oportunidades para el aprendizaje de los estudiantes. Las eva…
A Feasibility Study for the Transition to Electric Mobility in the Island of Favignana
2021
The energy transition and climate neutrality are a short time scenario as climate concerns are rising fast. Small islands are natural microgrids in which the energy transition is subjected to economic and regulatory constraints and highly challenged by technical issues. As a first step, the Mediterranean island of Favignana has been considered in this study, to assess how electric mobility could impact the power system. According to the plans from the local decision makers, the island is moving towards a full public electric mobility in the near term, also due to the participation in the BloRin project. For this reason, a feasibility study about the technical and environmental impact of ele…
Lithium-ion batteries for electric vehicles: combining Environmental and Social Life Cycle Assessments
2018
Electric vehicles (xEV) are a key low carbon technology for mobility. Although xEV have no tailpipe emissions, the production of traction batteries leads to environmental and social burdens. In this context, authors assess the environmental and social impacts of a cell of Lithium ion traction battery in order to identify the most relevant aspects and the potential added value of performing both the assessments. Results show the relevance of the resources in terms of both environmental and social impacts. Moreover, the social assessment results pointed out the relevance of the geographical boundaries, often overlooked for in the environmental analysis. The combination of both the assessment …
