This work is concerned with the development of computational tools for the solution of reaction-diffusion equations from the field of computational electrocardiology. We designed lightweight spatially and space-time adaptive schemes for large-scale parallel simulations. We propose two different adaptive schemes based on locally structured meshes, managed either via a conforming coarse...

Our thesis is that the analysis of unstructured data supports software understanding and evolution analysis, and complements the data mined from structured sources. To this aim, we implemented the necessary toolset and investigated methods for exploring, exposing, and exploiting unstructured data.To validate our thesis, we focused on development email data. We found two main challenges in...

This article addresses three topics. First, it reports on the international interest in the health care reforms of Switzerland and The Netherlands in the 1990s and early 2000s that operate under the label “managed competition” or “consumer-driven health care.” Second, the article reviews the behavior assumptions that make plausible the case for the model of “managed competition.”...

This paper explores leadership and governance arrangements in seven developed health systems: Australia, England, Germany, the Netherlands, Norway, Sweden and Switzerland. It presents a cybernetic model of leadership and governance comprising three fundamental functions: priority setting, performance monitoring and accountability arrangements. The paper uses a structured survey to examine...

This article considers the potential for insurer competition to improve health system performance by strengthening purchasing. Economic theory suggests that insurer competition will enhance efficiency if: (1) people have free choice of insurer, (2) competition is based on price and quality rather than risk selection and (3) insurers have tools to influence health care costs and quality. The...

This paper considers the complex relation between migrants’ interest in their host country and their consequent civic or social engagement in the framework of processes of transition following the rupture of international migration (cf. Zittoun 2006). In phases of transition, migrants live processes of identity definition, sense-making of the situation and learning new knowledge and...

This study deals with entrepreneurial activities for which there has been growing interest in academic research in recent years. Research has shown that the risk of failure among new ventures can be estimated at more than 50% in the first year, rising to 85% over three years. Such a rate of failure suggests that new business development is problematic. Against this background, the overall...

In this thesis we discuss practical and theoretical aspects of various stochastic vehicle routing problems. These are combinatorial optimization problems related to the field of transportation and logistics in which input data is (partially) represented in a stochastic way. More in detail, we focus on two-stage stochastic vehicle routing problems and in particular on so-called a priori...

A behavioral approach studying inventory ordering decisions in Newsvendor settings dates back to the early 2000s. Two systematic biased behavioral patterns have been identified since: a pull-to-center effect, or the tendency to order too many costly (low-safety stock) products and too few cheap (highsafety stock) products relative to the optimal stock level; and a demand chasing bias, or the...

Open-world software systems are built by composing heterogeneous,third-party components, whose behavior and interactions cannot be fully controlled or predicted; moreover, the environment they interact with is characterized by frequent, unexpected, and welcome changes. This class of software exhibits new features that often demand for rethinking and extending the traditional methodologies...
