SICUREZZA E POTENZA NEL XXI SECOLO - IL RUOLO DEL CAUCASO MERIDIONALE E DEL CASPIO
No full textIl Cuacsao meridionale costituisce uno spazio politico al tempo stesso frammentato e nel quale si innestano un pluralità di rapporti di interdipendenza tra attori esterni e interni alla regione. Questo capitolo, alla luce delle considerazioni appena svolte, intende approfondire le dinamiche tra attori locali, potenze regionali (Russia) e attori esterni (USA, UE e NATO) al fine di individuare il loro impatto sul sistema internazionale
LA COMPETIZIONE NAVALE NEL MAR CASPIO
No full textIl contributo, prendendo in considerazione i recenti sviluppi in ambito di infrastrutture portuali e assett navali nel mar Caspio, esamina, alla luce del modello del "dilemma della sicurezza" le possibili implicazioni delle politiche intraprese dagli attori della regione. In particolare, il capitolo considera due scenari, uno nel quale la navalizzazione del Caspio agisce come vettore di stabilità, l'altro nel quale invece costituisce il sintoma di una crescente competizione tra i paesi rivieraschi
Power and Security in the XXI Century. The South Caucasus and the Caspian Sea
No full textSouth Caucasus is among the most dynamic scenarios in terms of power distriubution within the International system. This chapter provides an illustration of the regional political process, emphazising the relationship among local powers, regional powers (Russia) and external actors (US, EU and NATO)

Il comportamento delle medie potenze in ambiente anarchico: un modello
No full textThis article proposes a theoretical model to study the behaviour of middle powers in the international system, as well as an empirical historical case study. In this perspective, the article is organized as follows. First, it shows that there is a gap as far as theoretical contributions to the topic is concerned. Secondly, it focuses attention on the incentives which define what a middle power’s dominant strategy is. Then, proceeding from the hypothesis that this class of states maximizes its advantage supporting international stability, it describes six different types of middle power and their behaviour. Finally, the last part of the work illustrates how the model fits with the case of Prussia’s foreign policy during the first part of the XIX Centur
LA RUSSIA E I SUOI CONFINI: UN'INTRODUZIONE
No full textIl volume si occupa del posizionamento strategico della Russia rispetto ai suoi ex-satelliti non meno che grandi potenze come Stati Uniti e Cina e, ancora, attori multilaterali come l'Unione Europea. La prospettiva di analisi è interdisciplinare, coerentemente con la natura della rivista Il Politico. I contributi scritti insieme a Giuseppe Iannini (co-curatore) e Francesco Marino (co-autore) hanno in un caso introdotto il tema degli interessi strategici di Mosca, nell'altro trattato la questione della navalizzazione del Mar Caspio in ottica di "dilemma della sicurezza"
GREEN TRIBOLOGY: WEAR EVALUATION METHODS FOR SUSTAINABILITY PURPOSES
No full textA sustainable development of machines, mechanisms and processes is one of the main goals of the 2030 agenda for Sustainable Development Goals (SDG). Currently, approximately 23% of the global energy consumption depends on inefficient performance of the tribological contacts. Particularly, about 20% of the energy loss is due to friction issues, and the remaining part is employed to remake and replace worn parts or to fix other wear-related failures. Green tribology is a crucial discipline for enhancing sustainability, because it is oriented at minimizing friction and wear phenomena. Therefore, wear evaluation is a fundamental starting point for designing new production or diagnostic techniques oriented to sustainability. In the industrial field this allows the optimization of design and processes, leading to reduction of pollution, minimization of energy dissipation and costs (SDG9, SDG12). In the field of human life, this can give a strong contribution to prevent damages, extending resistance and useful life of natural or prosthetic biocomponents, with an improvement of health and better life generation (SDG3). This paper presents and discusses various wear evaluation methods and related workflows with different purposes and benefits for sustainability. Some case studies demonstrate that wear evaluation substantially contributes at creating sustainable products and applications
Costanti e nuove dimensioni di confronto. Stati Uniti e Russia
No full textIl triennio 2020-22 ha modificato significativamente l’agenda politica internazionale, inducendo molti Stati a un ripensamento – quanto meno parziale – delle rispettive strategie nazionali. Oltre alle conseguenze sociali e sanitarie collegate alla diffusione del covid-19, gli Stati Uniti hanno affrontato tra la fine del 2020 e l’inizio del 2021 una profonda crisi istituzionale, innescata da un’inedita polarizzazione politica arrivata a maturazione negli anni della presidenza di Donald Trump. L’aggressione russa all’Ucraina, infine, è intervenuta a confermare l’instabilità degli assetti emersi dalla fine della Guerra fredda. Ha così fatto uscire la “nuova” Europa orientale dal cono d’ombra in cui era caduta dalla prospettiva di Washington, proprio mentre questa discuteva con i suoi alleati su quanto potesse essere allargato il raggio d’azione della nato rispetto al suo perimetro d’azione originale
Technology and International Relations: The New Frontier in Global Power
No full textExploring how changes in advanced technology deeply affect international politics, this book theoretically engages with the overriding relevance of investments in technological research, and the ways in which they directly foster a country’s economic and military standing. Scholars and practitioners present important insights on the technical and social issues at the core of technology competition. Technology and International Relations emphasizes the importance of leadership styles, domestic political agendas and the relative weight of technologically driven countries in global affairs. It highlights the now widely shared belief among both developed and developing countries that technology will be the defining factor in international politics. The book also unpacks the complexity of real-life cases of key technological advances, including artificial intelligence, UAVs, satellites and the responses of governments and the private sector to rising technological challenges
Sustainable Design of Machine Guards
No full textPromoting sustainable industrialization by fostering safety of machinery is a fundamental and ethical approach. Working in safe conditions is essential to comply with the UN’s Sustainable Development Goals (SDG) and, in particular, with SDG3 and SDG8, therefore making machines safer during their operation becomes a basic aim for a more sustainable society. From this perspective, the influence of certain design or/and physical parameters on machine safety must be necessarily analyzed even if standards do not consider them, with obvious advantages also in terms of industrial innovation, complying with SDG9. The present work refers to the study of machine protection panels to characterize their ability to resist ballistic penetration. In ISO 14120-Annex B, the methodologies and standards for the design and validation of machine guards are described, but the influence of many characteristics and parameters has not been considered to characterize the protection performance. This paper presents some results in the terms of withstanding capacity of polycarbonate panels to ballistic penetration considering the size of the guards and their ageing condition due to solar radiation. The analyses for the inspection of the through-hole cracks and deformation of the panels have been performed with an innovative method by using a metrology grade 3D optical scanner and 3D inspection techniques
