Collaborative Governance in Portugal? A Critical Perspective Based on an Empirical Survey
2020
A governança colaborativa constitui um tipo de processo de tomada de decisão e de ação coletiva em que entidades governamentais e agentes privados interagem como parceiros em pé de igualdade com o intuito de alcançar resultados benéficos para ambas as partes. Investigadores a favor do uso da governança colaborativa em Portugal tendem a apresentar os méritos da mesma de uma forma bastante positiva. Estes investigadores argumentam que essa forma de governança é a potencialmente mais apropriada em Portugal devido às tendências burocráticas e paternalistas do sistema de planeamento português. Esta perspetiva é a oposta à de autores mais críticos – dentro dos quais nos incluímos – que consideram…
La cultura del piano e il turismo relazionale integrato
2017
L’autore principale, alla data di pubblicazione del saggio, è responsabile del Laboratorio in Pianificazione Territoriale nel corso di Laurea in Pianificazione Territoriale Urbanistica e Ambientale dell’Università di Palermo. Considerando il quadro delle modalità di insegnamento della disciplina della pianificazione territoriale, la morfologia urbana e territoriale è la prevalente tipologia di approccio alle pratiche di trasformazione caratterizza le metodologie didattiche nelle scuole di architettura, mentre le teorie, da cui tali metodologie discendono, restano ben distinte e distanti dai saperi prossimi (e indispensabili) all’urbanistica: ingegneria, scienze agrarie, geologiche, scienze …
I luoghi periferici in cui si abilita intelligenza collettiva
2019
Nelle periferie urbane in cui coesistono ampi margini alla modificazione, un surplus di spazi interstiziali e marginali, negli ultimi anni si sta dispiegando la proliferazione di esperienze che aprono il campo a un diverso modo di trasformare le città, in una sorta di resilienza locale alla crisi e al conseguente vuoto di welfare sociale. Uno sguardo alle pratiche in corso sembra indicare una tendenza a spostare l'asset di sviluppo dalla patrimonializzazione immobiliare ad una economia della conoscenza, in cui i beni dismessi si offrano come piattaforme abilitanti dell'azione collettiva, dispositivi spaziali in cui incanalare l'innovazione attraverso il riciclo. Se il Piano Periferie promos…
mCLT: an application for collaborative learning on a mobile telephone
2005
Mobile technologies offer new opportunities for distance learning and enable people to collaborate anywhere. This paper introduces an innovative mobile platform for computer-supported collaborative learning in which traditional methodologies of collaboration have been improved, based on 3rd-generation mobile telephones. Students can collect and share live data immediately, anywhere and at any time. This enables them to play an active role in the knowledge-building process. The mCLT is potentially an application for ubiquitous collaborative learning.
A grid of material and immaterial laboratories for supporting the sustainability of transportation: the RESET project in Sicily
2015
Transportation is a crucial sector, to be suitably approached in order of getting human activities in more environmentally sustainable paths. In fact, in developing, as well in less developing, countries people and freights mobility are responsible of important amount of pollutant emissions and are cause of significant levels of energy consumptions. In this paper, a Sicilian regional project is presented, aiming at establishing an interconnected grid of material and immaterial laboratories. These laboratories, that are devoted at inducing more virtuous behaviors in the transportation policies, are constituted by equipment and software tools, mainly located in the region’s universities, acti…
CFD simulations of early- to fully-turbulent conditions in unbaffled and baffled vessels stirred by a Rushton turbine
2021
Abstract Laboratory scale unbaffled tanks provided with a top cover and a baffled tank both stirred by a Rushton turbine were simulated by carrying out RANS simulations. Three different turbulence models were adopted (k- ω SST, k- e and the SSG Reynolds stress model) to predict the flow field and the relevant performance parameters (power and pumping numbers) of the tank operated from early to fully turbulent conditions. CFD results were compared with literature experimental data and DNS simulation results to validate and properly compare the models. In the range of Reynolds numbers investigated, results showed that, for the unbaffled tank, the SSG model based on Reynolds stresses is a bett…

Towards a business model for second-life batteries: Barriers, opportunities, uncertainties, and technologies
2023
Electric vehicles (EVs) and the recent pandemic outbreak give cities a new trend to primarily private and shared mobility with low noise and less air pollution. Crucial factors for the widespread of EVs are the electrical charging infrastructure, driving range, and the reduction of the cost of battery packets. For this reason, there is a massive effort from manufacturers, governments, and the scientific community to reduce battery costs and boost sustainable electrical production and distribution. Battery reuse is an alternative to reduce batteries’ costs and environmental impacts. Second-life batteries can be used in a wide variety of secondary applications. Second-life batteries can be co…
A Remuneration Model of Energy Community Members in Italy
2022
The Directive (EU) 2018/2001 (RED II) requires Member States to authorize the constitution of consumers as self-consumers of renewable electricity by ensuring them non-discriminatory and disproportionate treatment. Member States must establish a favorable framework for promoting and facilitating the development of self-consumption, including in collective form (art. 21). According to the Directive, the granting of rights to renewable energy self-consumers who act collectively allows to increase the energy efficiency of households and helps to combat energy poverty by reducing consumption and supply tariffs. In Italy, the decree n. 162/2019 and then amended with Decree 199/2021 has partially…
