When and how java developers give up static type safety

Mastrangelo, Luis ; Hauswirth, Matthias (Dir.) ; Nystrom, Nathaniel (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019INFO008.

The main goal of a static type system is to prevent certain kinds of errors from happening at run time. A type system is formulated as a set of constraints that gives any expression or term in a program a well-defined type. Besides detecting these kinds of errors, a static type system can be an invaluable maintenance tool, can be useful for documentation purposes, and can aid in generating ...

Direct and indirect effects based on changes-in-changes

Huber, Martin ; Schelker, Mark ; Strittmatter, Anthony

(Working Papers SES ; 508)

We propose a novel approach for causal mediation analysis based on changes-in- changes assumptions restricting unobserved heterogeneity over time. This allows disentangling the causal effect of a binary treatment on a continuous outcome into an indirect effect operating through a binary intermediate variable (called mediator) and a direct effect running via other causal mechanisms. We identify...

Bank risk appetite in a world of CoCos

Aquila, Cecilia ; Barone Adesi, Giovanni (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018ECO015.

We investigate the shape of risk appetite when the bank is financed also with contingent convertible bonds (CoCos). Our contribution to the existent literature is to assess risk appetite in a multi-dimensional perspective and to account for differences among banks' clusters, especially in a world with CoCos and policy rates approaching zero or negative figures. In our model, the bank objective...

Absorb bioresorbable scaffold versus xience metallic stent for prevention of restenosis following percutaneous coronary intervention in patients at high risk of restenosis: rationale and design of the COMPARE ABSORB trial

Chang, Chun Chin ; Onuma, Yoshinobu ; Achenbach, Stephan ; Barbato, Emanuele ; Chevalier, Bernard ; Cook, Stéphane ; Dudek, Dariusz ; Escaned, Javier ; Gori, Tommaso ; Kočka, Viktor ; Tarantini, Giuseppe ; E.J.West, Nick ; Morice, Marie-Claude ; G.P.Tijssen, Jan ; Geuns, Robert-Janvan ; C.Smits, Pieter

In: Cardiovascular Revascularization Medicine, 2019, vol. 20, no. 7, p. 577–582

Background: The advent of bioresorbable vascular scaffolds (BVS) was considered as a potential improvement in percutaneous coronary intervention (PCI) after the groundbreaking development of drug eluting stents (DES). However, the clinical performance, long-term safety and efficacy of BVS in complex coronary lesions remain uncertain. COMPARE ABSORB, a multicenter, single blind, prospective ...

Fast and automatic assessment of fall risk by coupling machine learning algorithms with a depth camera to monitor simple balance tasks

Dubois, Amandine ; Mouthon, Audrey ; Sivagnanaselvam, Ranjith Steve ; Bresciani, Jean-Pierre

In: Journal of NeuroEngineering and Rehabilitation, 2019, vol. 16, no. 1, p. 71

Falls in the elderly constitute a major health issue associated to population ageing. Current clinical tests evaluating fall risk mostly consist in assessing balance abilities. The devices used for these tests can be expensive or inconvenient to set up. We investigated whether, how and to which extent fall risk could be assessed using a low cost ambient sensor to monitor balance tasks.Method:...

Modeling latent variables in economics and finance

Bluteau, Keven ; Ardia, David (Dir.) ; Boudt, Kris (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2019 ; 2758.

Le sujet des variables latentes est au cœur de cette thèse. Ces variables latentes (i.e., non observables) doivent être inférées à l’aide de modèles statistiques ou de variables proxys observables. Les objectifs de ma thèse de doctorat sont de développer et de tester de nouveaux modèles statistiques pour déduire ces variables afin de les utiliser pour l’amélioration des décisions...

Monetary policy and interest rate products

Zurowski, Wojciech ; Schneider, Paul (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 20019ECO002.

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...
