Eugenio Elia Levi: Le speranze perdute della matematica italiana. E-book. Formato PDF Andrea Celli   -  Egea, 2016  - 

Eugenio Elia Levi è stato uno dei più grandi matematici italiani del ‘900 (come del resto il fratello Beppo). Morì nell’ottobre del 1917, ucciso da un cecchino, nelle fasi iniziali della disfatta di Caporetto. Attivo interventista, allo scoppio della prima guerra mondiale si era arruolato volontariamente nel Genio Zappatori e fu poi promosso capitano per meriti di guerra. Eugenio Elia Levi si era laureato in Matematica nel 1904, studiando alla “Normale” di Pisa dove ebbe come maestri Luigi Bianchi e Ulisse Dini. Nel 1909 ottenne la cattedra di Analisi infinitesimale presso l’Università di Genova. La sua produzione scientifica fu tanto profonda quanto differenziata – ha riguardato i gruppi di Lie, le equazioni alle derivate parziali e la teoria delle funzioni di più variabili complesse – e venne immediatamente apprezzata negli ambienti matematici internazionali.

Conflicts, Pandemics and Peacebuilding: New Perspectives on Security Sector Reform in the MENA Region. E-book. Formato EPUB Andrea Cellino   -  Ledizioni, 2021  - 

The Covid-19 pandemic is not only a health challenge. In the MENA region, against the backdrop of protracted conflicts, instability, and an overall deterioration in socio-economic conditions, the coronavirus crisis adds another layer of vulnerability and has already had long-lasting repercussions on human security across the region. Moreover, as hybrid actors take on an important role as security providers amid the pandemic in a context of limited or absent oversight, risks associated to a lack of accountability, ethno-religious discrimination, human rights abuses, and gender-based violence grow. While classical approaches to security provision tend to portray non-state actors and the State as inherently at odds, the complexity of a rapidly evolving security landscape throughout the region should trigger a revision of the very concept of effective governance. Against this backdrop, how should Security Sector Reform (SSR) strategies and programmes adapt? What lessons can be drawn from selected case studies such as Iraq, Libya, and Yemen?

Institutionalised (In)security: Exploring The Mena Region’s Governance Crises. E-book. Formato EPUB Andrea Cellino   -  Ledizioni, 2021  - 

After a decade of popular uprisings and civil wars, the Middle East and North Africa (MENA) region experiences a deep governance crisis. The transformation, weakening or even the collapse of state institutions has changed the security framework, with direct implications for the safety and security of civilian populations across the region. Security Sector Governance and Reform (SSG/R) has to cope with hybridity and institutional fatigue.This report explores the MENA region’s governance crises, providing case studies on Libya, Iraq, Tunisia, and Yemen. How can we effectively bring about meaningful SSG/R in hybrid security orders? In which way is “institutionalised insecurity” challenging traditional patterns of governance in vulnerable settings?
