MINE - Mobile Learning in Higher Education
2018
Mobile technologies are an important part of our daily life and we carry them with us all the time. Mobile learning is already used a lot in informal and non-formal learning, but in the context of formal learning it is not much used, yet. In the area of formal learning at universities, there is a great need for pedagogic scenarios to encourage educatorsto use these new technologies. It is suggested that educators will need to move beyond the didactic approaches still frequently found in higher education. Social constructivist approaches have been advocated, along with the development of communities of practice to support educators. In addition, more emphasis on learners is required, to unde…
Winter long dry spells in the Mediterranean basin and associated atmospheric conditions : contemporary and future variability (1957-2100)
2017
In the context of climate change, as reflected by a dryer Mediterraneanbasin, this thesis focused on the study of the contemporary and future variability(1957-2100) of the wintertime (September to April) very long dryspells events (called VLDSe) in the Mediterranean basin. An original methodologywas developed in this thesis in order to define VLDSe as singularclimatic events, characterized by location, duration and spatial extent criteria.76 VLDSe were detected in the Mediterranean basin on the contemporaryperiod (1957-2013). These events are divided into 4 main geographicalpatterns: North-East, West, Scattered Localized and South-East. North-East and West configurations are associated with…
Supporting the Sustainable Energy Transition in the Canary Islands: Simulation and Optimization of Multiple Energy System Layouts and Economic Scenar…
2021
The Canary Islands have great potential for the implementation of sustainable energy systems due to its availability of natural resources. The archipelago is not connected to the mainland electricity grid and the current generation system is mainly based on traditional fossil fuel. Therefore, the islands strongly dependent on fuel importations, with high costs due to logistics. Furthermore, due to the inadequate coverage of residential heating and cooling needs, the per capita energy consumption is far below the Spanish national average. This occurrence has inspired an intense debate on the current development model of the Canary Archipelago, which has led to the implementation of actions a…
Environmental assessment of 2030 electricity generation scenarios in Sicily: An integrated approach
2020
Abstract This paper deals with the environmental assessment of two electricity scenarios in Sicily, for 2030, characterized by a high exploitation of renewable energy sources in order to quantify the potential contribution of the local strategies in the achievement of the European climate policies and the potential improvement in the future electricity mix, compared to the current one (2014). In order to match these goals, authors integrate the Life Cycle Assessment with a scenario analysis. The future electricity mix scenarios, characterized by a share of renewables (57% for 2030-BS scenario and 51% for 2030-DS scenario) show a reduction of the greenhouse gases emissions per kWh of electri…
Life-Cycle Assessment Applied to Future Scenarios of Electricity Generation in Sicily
2018
Fighting global warming and increasing the energy security are some of the most relevant objectives of the European energy policy. Thus, defining potential low carbon pathways for the energy sector is of paramount importance in order to identify strategies with the lowest impact on climate. This paper presents an overview of environmental assessment of future electricity scenarios in Sicily (Italy), for 2020 and 2030, characterized by a high exploitation of renewable energy sources. Authors apply the Life Cycle Assessment methodology, according to the standard of the ISO 14040 series, in order to evaluate the environmental impacts of electricity generation in the future scenarios in compari…
Lévy processes in bounded domains: path-wise reflection scenarios and signatures of confinement
2022
We discuss an impact of various (path-wise) reflection-from-the barrier scenarios upon confining properties of a paradigmatic family of symmetric $\alpha $-stable L\'{e}vy processes, whose permanent residence in a finite interval on a line is secured by a two-sided reflection. Depending on the specific reflection "mechanism", the inferred jump-type processes differ in their spectral and statistical characteristics, like e.g. relaxation properties, and functional shapes of invariant (equilibrium, or asymptotic near-equilibrium) probability density functions in the interval. The analysis is carried out in conjunction with attempts to give meaning to the notion of a reflecting L\'{e}vy process…
Tectonic Sustainable Building Design for the Development of Renovation Scenarios – Analysis of ten European renovation research projects
2018
The investigation of 10 European building renovation research projects presented in this paper demonstrates that recent research in this field is currently centralized around quantifiable objectives i.e. development of energy efficient renovation scenarios, whereas the more qualitative objectives in renovation projects such as aesthetics, identity and/or social dimensions are rarely addressed. Furthermore, the result of this investigation together with the recent researches about the current practice of building renovation indicates that many of renovated buildings, which now are claimed to be sustainable are not addressing all aspects of a conventional definition of sustainability. Lastly,…
Sähköä ja alkemiaa: Tekoälydiskurssit Yleisradion verkkoartikkeleissa
2021
Tässä artikkelissa tarkastelemme sitä, millaisena ja miten tekoäly esitetään suomalaisessa julkisessa keskustelussa, ja ketkä tekoälystä suurelle yleisölle kertovat. Aineistona olemme käyttäneet Yleisradion verkkosivujen tekoälyä käsitteleviä artikkeleja. Tulosten perusteella tekoälystä pääsevät kertomaan useimmin talouden ja teollisuuden aloilla työskentelevät miehet. Aineistossa esiintyneet tekoälytulevaisuuskuvaukset pitäytyvät pitkälti nykyisen länsikeskeisen kapitalistisen maailmankuvan sisällä. Toisin sanoen, ne eivät haastaneet tai ylittäneet vallitsevaa status quoa, vaan näkivät tulevaisuuden pikemminkin lineaarisena kehityksenä nykytilasta. Aiemman tutkimuksen perusteella yleinen k…
Abitare nel reale. Dalla crisi della periferia alla tessitura di nuove relazioni contestuali
2019
I progetti redatti per “Palermo Sud-Est” sono il risultato di un Laboratorio di Laurea strutturatosi attraverso incontri, seminari, comunicazioni specialistiche, esposizioni critiche, che – in una strategia condivisa – ha visto ogni studente elaborare il proprio lavoro nel confronto con gli altri attori del Laboratorio stesso. La ricerca sui “progetti urbani” è stata impostata di modo che ogni laureando fosse messo a conoscenza dei progetti svolti nello stesso ambito territoriale dai colleghi che l’avevano preceduto, così da poter operare in continuità e contribuire a formulare un ragionamento unitario, nel quale ogni progetto costituisse continuazione, verifica o anche variante dei precede…
La cultura ci salverà? Processi di touristification a base culturale nel centro storico di Palermo
2023
Negli ultimi tre decenni la cultura ha avuto un ruolo chiave nella costruzione delle politiche urbane, divenendo uno strumento decisivo nella definizione delle strategie di sviluppo economico e nell’accesso alla competizione globale che caratterizzano l’attuale regime di neoliberismo urbano (Miles e Paddison 2005). Anche nel sud Europa la cosiddetta rigenerazione a base culturale ha rappresentato e continua ancora oggi a rappresentare una vera e propria ortodossia urbana, che trova nel turismo tanto una ragione di esistenza quanto un campo di attuazione. In particolare, negli ultimi anni i centri storici di molte città sudeuropee sono stati oggetto di trasformazioni profonde in cui pratiche…
