Algoritmi esatti per il Job Shop Scheduling: approcci Mathematical Programming

In questa tesi ci occuperemo di fornire un modello MIP di base e di alcune sue varianti, realizzate allo scopo di comprenderne il comportamento ed eventualmente migliorarne l’efficienza. Le diverse varianti sono state costruite agendo in particolar modo sulla definizione di alcuni vincoli, oppure sui bound delle variabili, oppure ancora nell’obbligare il risolutore a focalizzarsi su determinate decisioni o specifiche variabili. Sono stati testati alcuni dei problemi tipici presenti in letteratura e i diversi risultati sono stati opportunamente valutati e confrontati. Tra i riferimenti per tale confronto sono stati considerati anche i risultati ottenibili tramite un modello Constraint Programming, che notoriamente produce risultati apprezzabili in ambito di schedulazione. Un ulteriore scopo della tesi è, infatti, comparare i due approcci Mathematical Programming e Constraint Programming, identificandone quindi i pregi e gli svantaggi e provandone la trasferibilità al modello raffrontato.

Anna, sette anni al fronte. Analisi e proposta di sottotitolaggio del film documentario Anna, sem' let na linii fronta

The aim of the present work was to make more accessible a documentary film that focuses on the life and work of the Russian journalist killed in Moscow in 2006: Anna Politkovskaja. The film, entitled “Anna, seven years at the frontline” is a collage of several video-interviews with Politkovskaja’s friends and colleagues, in which they talk about who she was, what was her job about and how she tried to make the public aware about the Chechen wars. Working on this translation gave me a unique opportunity to deepen one of the most controversial issues in the recent history of Russia and to create a useful final product for those who have a particular interest in this topic but do not have the necessary linguistic competence to understand this documentary film.

Interpretare per il Tribunale penale internazionale per il Ruanda. Il trauma vicario e le sue conseguenze sul lavoro degli interpreti.

This dissertation discusses the professional figure of interpreters working for the International Criminal Tribunal for Rwanda (ICTR). The objective is to investigate specific job-related stress factors, particularly the psychological consequences interpreters may have to face, the so-called vicarious trauma. People working for the ICTR are exposed to genocide victims’ violent and shocking testimonies, a situation that could have negative psychological impacts. Online interviews with some interpreters working for the ICTR were carried out in order to arrive at a more thorough understanding of this topic. The study is divided into four chapters. Chapter I outlines the historical aspects of the simultaneous interpreting service in the legal field at the International Military Tribunal, in the trials of the Nazi leaders, and then it analyses a modern international criminal jurisdiction, the ICTR. Chapter II firstly discusses the differences between conference interpreting and court interpreting and in the second part it investigates job-related stress factors for interpreters, focusing on the legal field. Chapter III contains a detailed analysis of vicarious trauma: the main goal is to understand what psychological consequences interpreters have to cope with as a result of translating abused people’s accounts. Chapter IV examines the answers given by ICTR interpreters to the online interviews. The data collected from the interview was compared with the literature survey and the information derived from their comparison was used to put forward some suggestions for studies to be carried out in the future.
