ON HIGH-SKILL AND LOW-SKILL EQUILIBRIA: A MARKOV CHAIN APPROACH

2006

In this paper we propose to study the dynamics of human capital accumulation by means of a Markov chain. We identify the conditions for the emergence of ergodic and nonergodic dynamics, and relate them to various characteristics of an economic system. The model may generate high-skill and low-skill equilibria as well as intermediate situations. Policy implications are also discussed.

Economie assessments on the use of wired and wireless recharging systems in Italian and European market

2017

The conductive charging method for the electric vehicles is the most widespread, since it is the simplest and has higher returns. In the last years, alternative charging technologies have been investigated. Between these wireless charging systems have been large diffusion and have been commercialized by some manufacturer. Wireless charging systems for electric vehicles have some advantages respect the wired ones, not obliging the user to connect physically the vehicle to the electric charging station. Assuming the efficiency declared by the manufacturer of wireless systems the authors, in this paper, estimate the maximum cost that wireless recharging systems can have to be, however, more fa…

Viaggi nell’immaginario: il turismo virtuale nel sito UNESCO di Tarragona

2023

Le nuove tecnologie hanno trasformato in modo radicale non solo la geografia come disciplina, ma anche le geografie del mondo. Il digitale ha assunto, infatti, un ruolo di mediazione sempre più pervasivo nella produzione dello spazio, come delle conoscenze e degli immaginari geografici. Le possibilità offerte dal virtuale, in particolare, offrono oggi un contributo decisivo nella comunicazione dei significati attribuiti ai luoghi e rispondono in modo sempre più efficace ai bisogni emergenti del settore turistico. Le esperienze di visita mediate dal digitale mirano a coinvolgere i sensi e risultano efficaci quando promuovono immersioni rigorosamente realistiche. Nel quadro di queste riflessi…

New technologies have radically transformed not only geography as a discipline but also the geographies of the world. Indeed the digital has assumed an increasingly pervasive mediating role in the production of space as of geographic knowledge and imaginaries. The possibilities offered by the virtual in particular now offer a decisive contribution in communicating the meanings attributed to places and respond increasingly effectively to the emerging needs of the tourism sector. Digitally mediated visitor experiences aim to engage the senses and are effective when they promote rigorously realistic immersions. Within the framework of these reflections the paper highlights the renewed relevance of authenticity both of the tourism experience and of cultural heritage in relation to its potential for attraction and proposes a contextualization of the theme in light of the unprecedented opportunities granted by technologies for the creation of virtual and augmented spaces. The proposed discussion is therefore also a journey aimed at exploring authenticity as a tool through which new technologies can effectively mediate a sense of place and foster brand communication of a destination. The case study is the UNESCO site of Tarragona whose most relevant image for urban policies is presented. This shared figuration spatially defined and rooted in a precise historical moment is reconstructed on the one hand through the analysis of functional documentation for the candidacy and on the other by means of a review of mobile applications developed for the promotion of the city's cultural heritage. The proposed journey and exploration of the place return in light of the research data and in conclusion the central role played by digital technologies in mediating the UNESCO imaginary. The forms of virtual tourism in Tarragona confirm that to travel is to experience a text enveloped in time and inscribed in space.Settore M-GGR/01 - Geografia

The Necessary Integration of Green Infrastructures in the Public Transport Infrastructure Design

2021

The spatial planning of the new infrastructures for the urban mobility can provide the opportunity for the development of the urban green areas toward the condition of a healthy city. Elements such as architectural, heritage, and landscape centralities can lead to build a converging point between the two infrastructural systems of green and mobility. The development of the new urban railway lines in the city of Palermo (Italy) offers the chance to apply an integrated approach to the field. The local potentials of the biodiversity on one side and the fragmented landscape and environment systems on the other side build the framework for the development of a case study oriented to the enhancem…

EU transition in power sector: How RES affects the design and operations of transmission power systems

2019

In the past, much of Europe's electricity grid network has been designed in consideration of the locations of conventional generation plants. However, a large share of today's renewables production – notably variable wind and solar – does not correspond to this grid architecture. Interconnectors, in addition to internal infrastructure, are key to creating new electricity corridors to connect areas of surplus to areas of scarcity. In this context, in 2014 the European Council, in recognizing that a fundamental role of transmission infrastructure is to enable the integration of areas of high renewable energy potential with main consumption areas, endorsed the proposal by the European Commissi…

Reduction of the uncertainty in the measurements of magnetic fields

2014

The paper deals with magnetic field measurement, carried out by using a broadband and isotropic instrument. These measurements are characterized by a very high uncertainty values if compared with the ones usually related to other electrical measurements. For these reasons, if the measurements are performed to assess the exposure of human beings, these large uncertainty values imply a high risk of wrong decision when there is the need to establish if a site complies or does not comply with a specified emission limits. A reduction of the uncertainty values implies a reduction of the risk. With this aim, we propose an approach which, in particular but very typical cases, allows an effective re…

Reduction of Nitrates in Waste Water through the Valorization of Rice Straw: LIFE LIBERNITRATE Project

2018

An improved and more sustainable waste management system is required for successful development of technologies based on renewable sources. Rice straw is submitted to controlled combustion reactions and the produced ashes are chemically treated to produce silica. After a chemical activation step, the activated silica shows potential as an adsorbent agent and will be used to remove the excess of nitrates in groundwater and wells in the area of Alginet (Valencia, Spain), selected as a vulnerable zone within the Nitrates Directive. The demonstration activity aims to have a local impact on municipalities of 200 inhabitants or fewer, decreasing from current nitrate concentrations close to 50 mg/…
