This paper examines some standard open-economy New Keynesian models to address the question of how globalisation affects the inflation process. Specifically, it investigates how the Phillips curve for consumer price inflation in a country is affected by openness, and how the optimal choice of monetary policy is influenced by openness. The paper compares models that assume producer currency pric...

The game of football demands new computational approaches to measure individual and collective performance. Understanding the phenomena involved in the game may foster the identification of strengths and weaknesses, not only of each player, but also of the whole team. The development of assertive quantitative methodologies constitutes a key element in sports training. In football, the predictab...

In this paper, we propose a refinement of Chevallard’s algebraic modeling while still fully agreeing with his position that it is a key process in knowing mathematics. In doing so, based on our empirical study, we claim that: 1) there are two other stages in the algebraic modeling process; 2) it is nonlinear; and 3) partial models are constructed as well. Research on Chevallard's modeling persp...

We present a novel and fast algorithm to solve the Perspective-n-Point problem. The PnP problem estimating the pose of a calibrated camera based on measurements and known 3D scene, is recasted as a minimization problem of the Object Space Cost. Instead of limiting the algorithm to perspective cameras, we use a formulation for general camera models. The minimization problem, together with a quat...

While endodontic (dentoalveolar) abscesses can cause significant morbidity, in susceptible individuals they can pose life-threatening problems. This paper provides an overview of the more serious sequelae of endodontic abscesses, and provides examples of ‘high risk’ situations in practice in which these serious complications are more likely to occur.

In this paper the architecture and implementation of Cooperative Information Agents (CIA) is described. Taking a language-action perspective to the design of CIAs allows for the specification of obligations and authorizations, and results in the separation of tasks (things the agentmust do) and contracts (mutually agreed commitments to the course of communication). The architecture describes th...

Good communication is the basis for effective cooperation. An area where cooperation is essential is multidisciplinary healthcare. In this paper we will present a research project that aims at promoting effective multidisciplinary communication in a healthcare environment. We will answer the question of whether empirical modelling of the communication and cooperation patterns can be done based ...

When people or organizations provide information, they make choices regarding what they include and how they represent it. These two aspects combined (the content and the stance) represent a perspective. Investigating perspectives can provide useful insights into the reliability of information, changes in viewpoints over time, shared beliefs among social or political groups and contrasts with o...
