Performance Improvement of a Drag Hydrokinetic Turbine

2021

Hydropower is at present in many locations, among all the other possible renewable energy sources, the best one for net cost per unit power. In contrast to traditional installation, based on water storage in artificial basins, free flow river turbines also provide a very low environmental impact due to their negligible effect on solid transport. Among them, kinetic turbines with vertical axis are very inexpensive and have almost zero impact on fish and local fauna. In application to tidal waves and sea waves, where vertically averaged velocities have alternate direction, a Savonius rotor also has the advantage of being productive during the whole time cycle. In this work, the effect of an u…

A Cost–Benefit Based, Parametric Procedure to Screen Existing Irrigation and Municipal Supply Reservoirs for Wind Energy Storage

2018

Pumped hydro storage (PHS) is one of the more suitable energy storage technologies to provide bulk storage of intermittent renewable energy sources (RES) such as wind. Since the main limiting factors to the expansion of this mature technology are environmental and financial concerns, the use of an existing reservoir can help mitigate both types of impacts. In addition, the high number of reservoirs for municipal and irrigation supply in many areas of the world makes the idea of using PHS as a relatively diffuse, open-market, technology for RES management attractive. These arguments in favor of PHS must, however, be convincing for investors and regulators from an economic standpoint. To this…

Land Cadastre in Italy for Sustainable Development: Application to Two Parcels of Land in a Geopark in the Process of Being Defined in Corleone (PA-I…

2020

Geoparks, like all parks, are UNESCO awards for a sustainable management of all resources and therefore also of human life. Environmental emergencies such as climate change, pollution, soil erosion, salinisation, and fires that, together with health emergencies, undermine life on earth, require intervention. The widespread sustainable management of the territory of a municipality, a region, a nation, or all of them (European Union) allows to widen the application of these concepts to reach the limit of a planet that guarantees life for future generations. The work after having exposed the motivations of the geopark (an initiative born by chance), i.e. the surface where the environmental bea…

EU Cultural Security Law in an Educational Context

2021

Cultural security is a comprehensive notion that has gained much attention in the recent cultural heritage debates. In terms of the EU, it encapsulates cultural heritage destruction and protection in armed conflicts, post-war cultural heritage management, restitution, illicit traffic of cultural property, cultural diversity, and intercultural dialogue. The article aims to present how cultural security matters appear in the EU legal system and policy. The authors argue that cultural security is present in different policies regarding cultural property and the fight against illicit trafficking, as well as in EU external cultural relations. Digitization in the cultural sector constitutes a cha…

Carbon emissions by Ssouth american companies: driving factors for reporting decisions and emissions reduction

2018

In the last decade, companies have started to disclose information on carbon emissions. To our knowledge, this is the first paper to look into this phenomenon in South America, which is a very important geographical area regarding climate change because of the local nature and developing economies. This paper explores the relationships between some corporate variables and two important decisions: (i) whether to report carbon emissions, and (ii) the impact on the evolution of carbon emissions. Logit and linear panel data models are used to determine the driving factors for decisions (i) and (ii). Our results show that regarding the carbon reporting decision, a company&rsquo

Mayors, Using Cultural Expenditure in An Opportunistic Way Improves the Chances of Re-Election, but Do Not Do It: Revisiting Political Budget Cycles

2020

This article analyzes whether expenditure on the provision of merit goods, culture, health, education, and sports, by local governments, in medium-sized cities (between 20,000 and 100,000 inhabitants) is tied to the electoral cycle

Transformative Policies for the Social and Solidarity Economy: The New Generation of Public Policies Fostering the Social Economy in Order to Achieve…

2020

The United Nations Agenda 2030 has recognized that Social Economy (SE) entities play an important role in achieving the Sustainable Development Goals (SDG). In order to maximize the impact of the SE, governments have recently deployed new policies regarding these entities. The objective is to understand the context of policy change that has allowed these policies to emerge, their main characteristics and the critical factors in their construction and implementation. Successful policy cases in Europe and Spain have been studied. Qualitative data have been collected through key policy documents, experts, and focus groups. As a main finding, the study shows that this new model of policies exhi…

Penyagolosa Trails: From Ancestral Roads to Sustainable Ultra-Trail Race, between Spirituality, Nature, and Sports. A Case of Study

2019

[EN] The organization of an open-air sporting event involves a series of challenges. People are drawn by the desire to do sport, preferably in close contact with nature, so as to complement healthy lifestyles, and in search of air purity. Sporting organizations are increasingly searching for new locations that do not only attract athletes, but spectators and companions too. Races in natural parks provide the additional benefit of doing sport in a unique space, usually a transmitter of simplicity, pure air, and tranquillity. Organizing a mountain race in a natural park implies some issues. These are areas of great environmental richness that must be protected. Natural parks are places of ind…

Towards a sustainable leader-follower relationship: constructive dissensus, organizational virtuousness and happiness at work (haw)

2020

This paper examines how leaders and followers can interact positively under complex and bounded conditions. For this purpose, this paper conceptualizes and measures the concept of constructive dissensus. Constructive dissensus relates to a mutual understanding leading to a situation of coregulation. In addition, the relationship between constructive dissensus and happiness at work is examined on the basis of affective events theory. Furthermore, the mediating role of organizational virtuousness is assessed. Through structural equation modeling, a multilevel analysis was performed. Data from 130 bank branches and 606 employees were gathered. The results reveal a direct effect of constructive…
