In-Between ‘Smart’ Urban Growth and ‘Sluggish’ Rural Development? Reframing Population Dynamics in Greece, 1940–2019
2020
Multifaceted demographic dynamics have shaped population growth in Mediterranean Europe, reflecting a metropolitan cycle from urbanization to re-urbanization. To assess the distinctive impact of economic downturns on population dynamics, the present study illustrates the results of an exploratory analysis that assesses urban expansion and rural decline at various temporal scales in Greece, a peripheral country in southeastern Europe. Statistical analysis based on multivariate exploratory techniques outlined the persistent increase of regional populations, evidencing the distinctive role of agglomeration/scale with urbanization and early suburbanization phases (1940&ndash
Suburban Fertility and Metropolitan Cycles: Insights from European Cities
2021
Being largely diversified along the urban–rural gradient, fertility gaps have demonstrated to fuel metropolitan expansion, contributing to natural population growth and social change. In this direction, population dynamics and economic transformations have continuously shaped urban cycles in Europe. Assuming suburban fertility to be a relevant engine of metropolitan growth, the present study investigates and discusses the intrinsic relationship between fertility transitions and urban expansion, focusing on European metropolitan regions. An average crude birth rate referring to the last decade (2013–2018) was estimated from official statistics at 671 Functional Urban Areas (FUAs, Eurostat Ur…
Modelling, Simulation and Characterization of a Supercapacitor in Automotive Applications
2020
The energy storage is one of the most discussed topics among Electrical Vehicles (EVs) research. Currently, supercapacitors (SCs) are collecting even more attention due to their unique features such as high-power density, high life cycle and lack of maintenance. In this paper, a supercapacitor model suitable for the simulation in automotive applications is identified. The model parameters are estimated and used to simulate the behaviour of a commercial SCs bank in different operating conditions. The model is finally validated considering experimental results.
Value co-creation and satisfaction in b2b context: a triadic study in the furniture industry
2020
Research on Value co-Creation (VcC) has been more extensive in B2C (business-to-consumer) than in B2B (business-to-business) and mainly for service contexts, under dyadic approaches (supplier&ndash
Energy needs and sustainable management of the energy cycle
2017
The issue of sustainability of the energy policies is analised in its manifold facets. An overview is given about the trend of global energy needs and energy production, analysing the geographic distribution of consumptions and the share of energy sources, on the basis of the statistics and projections published by major agencies. The issue of sustainability of the energy cycle is finally addressed, highlighting how the use of biomasses as an energy source and of hydrogen as an energy carrier are among the most promising approaches.
The Press as a Resource for Promoting Sustainability Competencies in Teacher Training: The Case of SDG 7
2022
Given the seriousness of the socio-environmental situation we are facing, this study aims to contribute to the involvement of teachers in education for sustainability through the use of non-formal education, particularly the press. The main objectives of the present study are to analyse the use of the press in science education, as well as the design, implementation and evaluation of tools aimed at teachers and trainee researchers in order to encourage and promote attention to the Sustainable Development Goals (SDGs) and more specifically SDG 7 (clean and affordable energy for all) in science education. The proposals are carried out using a constructivist methodology in sessions structured …
New frontiers in sustainable energy production and storage
2015
Evidently, one of the most effective ways to reduce CO2 emissions consists in the deployment of renewable energies, with the advantage of securing and expanding the energy supplies of a given country. The main problem that arises is due to the intermittent temporary character of many renewable resources like solar and wind. For this reason, it has been recently concluded that in case of high integration of renewables into the distribution grid (more than about 30% of the electricity mix), the implementation of energy storage systems together with smart grids is necessary. Therefore, renewable energies for large scale power production in country would usually require the availability of a su…
Liberalising European electricity markets: opportunities and risks for a sustainable power sector
2003
The process of liberalising European electricity markets, encompassing a wide range of restructuring activities, has mainly been spurred by the attempt to increase the economic efficiency of the whole sector. This process might be used to trigger a development towards a sustainable power sector by increasing the use of renewable energy sources and enhancing energy efficiency on the supply and demand side. However, by taking a closer look at the current trends of the European electricity markets, it becomes obvious that the liberalisation not only implies opportunities but also risks for the creation of a sustainable power sector. Many of these risks are due to market distortions and imperfe…
Adoption of Green Environmental Practices in Small and Medium-Sized Enterprises: Entrepreneur and Business Policies Patterns in Romania
2021
Current research shows that SMEs’ social and environmental actions are fragmented and informal, and few have formal policies and intentions. At the same time, many SMEs are engaged with environmental policies, often not knowing it. Concurrently, there is a gap between the pro-environmental attitudes of the SMEs managers, who are often seen as the main drivers for the firm’s behavior, and the policies implemented in reality in their firms. To this end, our research’s objective is to explore pro-environmental behavior, both at the individual and firm level, to identify connections between these levels and measures but also with firm’s and managers’ demographics, based on a study of Romanian S…
Analysis of the Impact of the Triple Helix on Sustainable Innovation Targets in Spanish Technology Companies
2020
The establishment of broad-based networks, such as the Triple Helix, for innovation and sustainability is sufficiently corroborated. In this work we suggest that the information received from the Triple Helix has a significant and different impact on the objectives of sustainable innovation, depending on whether companies cooperate or not. To this end, an empirical analysis of a stratified sample of more than 5000 Spanish medium and high technology companies in 2010-2014-2015 was carried out. The results confirm that companies that do not cooperate place more importance on the information received from the Triple Helix to establish their sustainable innovation targets.
