My PhD thesis consists of three papers which study how interest rate products' prices react to both the central bank's policy goals and communication. As tool I make use of various econometric techniques such as affine models, general method of moments or Haar like filtering. The first chapter studies government bond excess term premia. I show that their predictability is driven by monetary...

In finite element simulations, the handling of geometrical objects and their discrete representation is a critical aspect in both serial and parallel scientific software environments. The development of codes targeting such envinronments is subject to great development effort and man-hours invested. In this thesis we approach these issues from three fronts. First, stable and efficient ...

Non-linear phase field models are increasingly used for the simulation of fracture propagation problems. The numerical simulation of fracture networks of realistic size requires the efficient parallel solution of large coupled non-linear systems. Although in principle efficient iterative multi-level methods for these types of problems are available, they are not widely used in practice due to...

Middleware-based database replication protocols require few or no changes in the database engine. As a consequence, they are more portable and flexible than kernel-based protocols, but have coarser-grain information about transaction access data, resulting in reduced concurrency and increased aborts. This paper proposes conflict-aware load-balancing techniques to increase the concurrency and...

In this paper we investigate correctness criteria for replicated databases from the client's perspective and present their uniform characterization. We further study the effects of different consistency degrees in the context of three middleware-based replication protocols: primarybackup, optimistic update-everywhere and BaseCON, a simple yet faulttolerant middleware-based replication protocol...

Interactive applications, such as mobile or web apps, have become essential in our lives and verifying their correctness is now a key issue. Automatic system test case generation can dramatically improve the testing process for these applications and has recently motivated researchers to work on this problem defining a wide range of different approaches. However, most state-of-the-art...

Nel corso degli ultimi anni nello studio delle organizzazioni si è posto l’accento sull’influenza che le relazioni con altri attori hanno sullo svolgimento dell’attività caratteristica dell’organizzazione stessa. Considerando il museo come un’organizzazione che genera e intesse relazioni con altre istituzioni dello stesso tipo, o con soggetti operanti in settori diversi, è possibile...

La ricerca teorica di quelli che sono comunemente definiti come museum studies ha ottenuto negli ultimi vent’anni molta importanza a causa della grande difficoltà nel definire in maniera univoca l’istituzione museale. Un confronto tra i contributi sviluppati dai cosiddetti theorists e quelli che scaturiscono dalla pratica museale, può essere d’aiuto nell’esplorare il significato del...

La ricerca, partendo dal dibattito sul ruolo e la funzione del museo nella società moderna, suscita interrogativi sulle principale problematiche che i musei devono affrontare dovute ai cambiamenti nella società contemporanea. Il titolo della ricerca suggerisce l'adozione di un'approccio alternativo allo studio e all'analisi delle attività del museo tradizionale, infatti l'obiettivo dello...

Over the last two decades it has become increasingly important to promote the efficiency and improve the performance of natural monopolies operating within network industries. In line with this, different regulatory approaches have been designed aiming at preventing the abuse of monopoly power and at the same time enhancing the performance of regulated firms. The most widely adopted...
