La regolamentazione giuridica delle fonti di energia rinnovabili tra tutela dell'ambiente e tutela della concorrenza
No full textThis PhD thesis analyses, from a constitutional perspective, the different aspects distinguishing the legislation of renewable energy, which is the link between the economic development needs and those of environmental protection, and which allows the exploitation of natural resources within the limits of their capacity for restoration.
As for the abovementioned legislation, the intention of the author is to highlight the critical issues that identify the sector, but also to ascertain common evolutionary lines.
At the outset, attention is given to the evolution of the legal notion of the environment and the development of constitutional case law on such question, which profoundly affects the regulation of the energy sector.
Afterwards, the constitutional case law on renewable energy sources is analyzed, as it is considered particularly emblematic for the complexity of the division of legislative power between the State and the Regions, outlined by art. 117 of the Constitution, and the evolution of the principle of sustainable development.
Following a brief overview of the regulatory framework set up at the European level for the promotion of energy production from renewable sources, the evolution and analysis of subsidy systems shall be contemplated. In particular, the different support mechanisms shall be explained, which can be divided into quantitative systems and price-based systems, highlighting their respective critical profiles.
Finally, two in-depth analyzes shall be carried out in relation to areas that have experienced a profoundly different evolution, and which present particular problematic features.
The first concerns the photovoltaic sector, with particular reference to the slight linear evolution of "Conto energia" subsidy program.
The second in-depth enquiry consists in an analysis of the hydroelectric sector legislation, and it demonstrates the criticalities stemming from the strong regulatory uncertainty related to the revision of the legislation on public bids for the assignment of hydroelectric water concessions for hydroelectric purposes
The Concept of Sustainable Development in Global Law: Problems and Perspectives
No full textThe aim of this paper is to focus on the multidimensional aspect of sustainable
development and on the legal implications. Although in 1987 sustainable development was
defined by the United Nations Environment Programme as “development that meets the
needs of the present without compromising the ability of future generations to meet their
own needs”, nowadays it lacks a more precise legal definition; therefore, legislators
struggle to implement it effectively. Law should identify an adequate balance between all
the different interests involved, which are the expression of the interdependence between
social and economic development and environmental protection. This fascinating concept
has passed from the ethics field to the legal field, and, as a global issue, it has caused
interactions between international, European and national law. This process started in
international context (starting from the Declaration of the United Nations Conference on
the Human Environment in 1972), then in EU law (art. 2 TEEC, art. 1 European
Landscape Convention 2000). Even if the concept of sustainable development has been
included in many constitutions around the world, the lack of a precise legal definition
makes it difficult to find the right balance point to identify a kind of development that can
satisfy the necessities of human society. In our paper we propose to follow a two-step
approach. Firstly, we will describe the evolution of the concept of sustainable development
in the intersection of diverse rules stemming from different legal orders and the types of
coordination between the different levels. Then we will analyse the potential synergies
between these overlapping regulatory systems, in order to achieve a high level of
protection for the environment as a whole and to ensure a better future to the present and
new generations

So solo che c'è una legge. Non so altro. Esperienze di utenti stranieri e operati sanitari in materia di immigrazione e salute.
No full textLa salute e l'accesso ai servizi sociosanitari sono influenzati da determinanti sociali, tra cui un forte peso è rappresentato dalla cittadinanza dell'utente. Obiettivo dell'articolo è di presentare i risultati emersi da focus group con utenti stranieri e operatori sul tema immigrazione e salute per analizzare possibili barriere legate alla comunicazione, organizzazione e informazione che possono determinare accessi e/o percorsi di cura non tempestivi e inappropriati in un sistema sanitario pubblico, dove è comunque sancito il diritto di un'assistenza sanitaria universale. L'utilizzo della tecnica qualitativa dei focus group fa emergere criticità spesso non rilevabili dalle analisi quantitative e mette al centro l'esperienza raccontata che, senza pretese statistiche, è utile al fine di un possibile ripensamento dei servizi

Dall’utopia cozy alla distopia critica: poetiche solarpunk nell’opera di Becky Chambers, Andrew Dana Hudson e Cherie Dimaline
No full textThe term Solarpunk identifies a certain type of art, practices, communities and speculative narratives that imagine sustainable and radical futures, and is now rooted in the science-fictional imaginary. In this essay, I discuss three texts that constitute models for different solarpunk poetics: the novella A Psalm for the Wild-Built by Chambers, and the novels Our Shared Storm. A Novel of Five Climate Futures by Andrew Dana Hudson (2022) and The Marrow Thieves by Cherie Dimaline (2017). I start with some definitions of solarpunk to highlight the debates the term has generated; I then discuss the abuses of the solarpunk label, which it is important to come to terms with now that the term is gaining visibility. I then discuss how the three texts relate to these debates and then draw conclusions on how I visualise the continued relevance and generativity of solarpunk - developing a plurality of strategies, combining the registers of utopia and dystopia. I argue that solarpunk can come to represent a constellation of art forms and political reflections based on a mode of radical hope: a hope, in other words, that is an active instrument of struggle

No full textProgetti per l’Umanità. Rivoluzioni, Utopie e Ingegneria Sociale (Projects for Humankind. Revolutions, Utopias and Social Engineering) explores a variety of plans and attempts to transform human beings into something different and better. In particular, it engages with utopian thinking and its ineludible counterpart, dystopia; with moments of political, cultural or philosophical revolution aimed at triggering profound shifts in human life; and with different projects of social engineering to be accomplished through a variety of means such as education, propaganda or alterations to the human body or mind. The case studies included in this volume range from the 18th century to the present day, and involve disciplines such as literary and film studies, philosophy, political science and cultural history. In particular, the volume features essays on the following topics: mythology in German Romanticism; Martin Heidegger’s eschatology; Francesco Saverio Salfi’s essay on the 1783 earthquake in Calabria; the scapigliati writers Carlo Dossi and Giovanni Faldella; the utopian production of positivist anthropologist Paolo Mantegazza; the Proletkul’t movement; early Soviet children’s magazines; the political implications of Russian linguaculturology (lingvokul’turologija); Lafayette Ronald Hubbard’s Dianetics; Zulu intellectual and writer Herbert Dhlomo’s speculative fiction; “self-management” (autogestione) and the Italian Socialist Party in the 1970s; the current debate on surrogate motherhood; and Terry Gilliam’s dystopian film trilogy. Through these multiple perspectives, the volume argues that human projectuality is an anthropological constant throughout history that is both necessary for human existence and simultaneously fraught with dangers; and that it is therefore a crucial category to analyse reality and fiction alike

Abstract
SiC/SiC ceramic matrix composites (SiCf/SiC CMCs) are regarded as the new materials for the hot-section components of aircraft gas turbine engines, since they have one-third of the density of metallic superalloys, a higher temperature capability, good mechanical strength, and excellent thermal shock resistance. However, high-temperature water-vapor-rich combustion gases can induce severe surface recession phenomena in SiC/SiC leading to component failure. For this reason, it is necessary to design protective coatings, i.e., environmental barrier coatings (EBCs), able to protect the SiC/SiC surface in combustion environments. In the present work, ytterbium monosilicate (Yb2SiO5), stable when exposed to water vapor at high temperatures, and ytterbium disilicate (Yb2Si2O7), characterized by a thermal expansion coefficient closer to that of the substrate, were selected for a multilayer EBC system. EBCs were processed using the atmospheric plasma spray (APS) technique. A set of deposition parameters were tested, varying the power of the torch, and the composition and microstructure of the deposited coatings were studied in terms of porosity, crack density, and post-deposition phase retention by performing SEM, EDS, and XRD analysis. The results allow for the definition of the influence of deposition parameters on the final properties of multilayer EBC coatings
