De digitale revolutie

Maakt ICT ons nou knapper of juist dommer? In amper twintig jaar is het maatschappelijk leven voor een groot deel verplaatst naar de virtuele ruimte. Alles en iedereen wordt digitaal met elkaar verbonden. Wat is de invloed van al die nieuwe technologie op ons begrip van de wereld, op ons gedrag, op onze cultuur? Wat betekent het voor het onderwijs? Deze sessie bespreekt de rol van media voor onze cognitieve ontwikkeling. Daartoe worden de ervaringen met oude media zoals geschreven tekst, radio en TV gekoppeld aan de wereld van Twitter, Apple, Facebook en Google, en wordt de blik gericht op wat ons nog te wachten staat.

Serious gaming: wondermiddel of luchtkasteel?

Games voor onderwijs en training worden een serieuze zaak. Marktprognoses melden een jaarlijkse groei van 18% tot een wereldwijd volume van meer dan 5 miljard Euro in 2020. Games bieden leerlingen een virtuele praktijk, waarin ze actief kunnen oefenen. Studietaken worden levensechte uitdagingen die tot indringende leerervaringen leiden. Dat schept nieuwe mogelijkheden juist in het MBO, waar praktische ervaring vaak belangrijker is dan theoretische kennis. Deze sessie geeft een snelle update over serious games. Diverse game-mechanismen worden besproken aan de hand van actuele voorbeelden.

A Reliable Downscaling of ECG Signals for the Detection of T wave Heterogeneity Features

In cardiovascular disease the definition and the detection of the ECG parameters related to repolarization dynamics in post MI patients is still a crucial unmet need. In addition, the use of a 3D sensor in the implantable medical devices would be a crucial mean in the assessment or prediction of Heart Failure status, but the inclusion of such feature is limited by hardware and firmware constraints. The aim of this thesis is the definition of a reliable surrogate of the 500 Hz ECG signal to reach the aforementioned objective. To evaluate the worsening of reliability due to sampling frequency reduction on delineation performance, the signals have been consecutively down sampled by a factor 2, 4, 8 thus obtaining the ECG signals sampled at 250, 125 and 62.5 Hz, respectively. The final goal is the feasibility assessment of the detection of the fiducial points in order to translate those parameters into meaningful clinical parameter for Heart Failure prediction, such as T waves intervals heterogeneity and variability of areas under T waves. An experimental setting for data collection on healthy volunteers has been set up at the Bakken Research Center in Maastricht. A 16 – channel ambulatory system, provided by TMSI, has recorded the standard 12 – Leads ECG, two 3D accelerometers and a respiration sensor. The collection platform has been set up by the TMSI property software Polybench, the data analysis of such signals has been performed with Matlab. The main results of this study show that the 125 Hz sampling rate has demonstrated to be a good candidate for a reliable detection of fiducial points. T wave intervals proved to be consistently stable, even at 62.5 Hz. Further studies would be needed to provide a better comparison between sampling at 250 Hz and 125 Hz for areas under the T waves.

The economic crisis as a game changer? Exploring the role of social construction in sustainability transitions

Continuing economic turbulence has fuelled debates about social and political reform as much as it has stimulated actions and initiatives aimed at a more fundamental transition of dominant economic systems. This paper takes a transition perspective to explore, from a Western European viewpoint, how the economic crisis is actually viewed through a variety of interpretations and responded to through a range of practices. We argue that framing societal phenomena such as the economic crisis as "symptoms of transition" through alternative narratives and actions can give rise to the potential for (seemingly) short-term pressures to become game changers. Game changers are then defined as the combination of: specific events, the subsequent or parallel framing of events in systemic terms by engaged societal actors, and (eventually) the emergence of (diverse) alternative narratives and practices (in response to the systemic framing of events). Game changers, when understood in these terms, help to orient, legitimize, guide, and accelerate deep changes in society. We conclude that such dynamics in which game changers gain momentum might also come to play a critical role in transitions. Therefore, we argue for developing a better understanding of and methodologies to further study the coevolutionary dynamics associated with game changers, as well as exploring the implications for governance.

The Development of Public Finances and Role of Fiscal Constraints in a Monetary Union: Example eurozone

This thesis is about the development of public debt and deficit in the eurozone, which has been in the center of attention for much of the new millennium. The debt-to-GDP and deficit-to-GDP ratios have changed significantly during the period of the European monetary integration, with sharp increases in the levels since the beginning of the financial crisis. We view the levels both before and after the establishment of the European Central Bank. The subject is complemented by a study of the restrictions on fiscal policy in the eurozone. The thesis begins with a review of the most central agreements in the Economic and Monetary Union, namely the Maastricht Treaty, the Stability and Growth Pact and the Fiscal Compact. We study the instructions and requirements provided by these contracts, with the emphasis being on the debt and deficit values. Furthermore, we view two theories that aim to provide us with information, whether the fiscal restrictions are useful or not. The second and empirical part consists of review on the debt and deficit levels in practice. We take a close look on the values for each of the currency union members. The third and last part summarizes the findings, and analyzes the reasons behind the changes. The result of the thesis is, that even though the levels of public debt and deficit have worsened since the beginning of the financial crisis, tight rules on fiscal policy might not be the best possible solution. Private sector has played a crucial part in the increase of the debt levels, and tight rules have their impact on the long awaited economic growth in the eurozone. It is obvious, though, that some form of fiscal guidelines with scientific ground are needed in order to avoid excessive and harmful debt and deficit levels. The main task is to make these guidelines a more essential part of the fiscal policy in each of the member countries.

La política monetaria del eurosistema

El lo. de enero de 1999, Europa entró en una nueva era con la adopción de una moneda única -el euro- por parte de once de los quince Estados miembros de la Unión Europea. En este artículo se describe el marco para la ejecución de la política monetaria en la zona del euro. De conformidad con el tratado firmado en Maastricht el 7 de febrero de 1992, Alemania, Austria, Bélgica, España, Finlandia, Francia, Irlanda, Italia, Luxemburgo, los Países Bajos y Portugal sustituyeron su moneda nacional por el euro, ello. de enero de 1999, tomando como base los tipos de conversión fijos e irrevocables del 31 de diciembre de 1998. Preparándose para este momento, los once países habían aplicado políticas encaminadas a intensificar el grado de convergencia económica, estableciendo al mismo tiempo los marcos institucionales y jurídicos para la ejecución de una política monetaria única, tarea que realizará el eurosistema, constituido por el Banco Central Europeo (BCE), con sede en Francfort, y los bancos centrales nacionales de los once países de la zona del euro.

What Are Effective Program Characteristics of Self-Management Interventions in Patients With Heart Failure? : An Individual Patient Data Meta-analysis

Background To identify those characteristics of self-management interventions in patients with heart failure (HF) that are effective in influencing health-related quality of life, mortality, and hospitalizations. Methods and Results Randomized trials on self-management interventions conducted between January 1985 and June 2013 were identified and individual patient data were requested for meta-analysis. Generalized mixed effects models and Cox proportional hazard models including frailty terms were used to assess the relation between characteristics of interventions and health-related outcomes. Twenty randomized trials (5624 patients) were included. Longer intervention duration reduced mortality risk (hazard ratio 0.99, 95% confidence interval [CI] 0.97–0.999 per month increase in duration), risk of HF-related hospitalization (hazard ratio 0.98, 95% CI 0.96–0.99), and HF-related hospitalization at 6 months (risk ratio 0.96, 95% CI 0.92–0.995). Although results were not consistent across outcomes, interventions comprising standardized training of interventionists, peer contact, log keeping, or goal-setting skills appeared less effective than interventions without these characteristics. Conclusion No specific program characteristics were consistently associated with better effects of self-management interventions, but longer duration seemed to improve the effect of self-management interventions on several outcomes. Future research using factorial trial designs and process evaluations is needed to understand the working mechanism of specific program characteristics of self-management interventions in HF patients.

Intereses nacionales convergentes en una apuesta colectiva: la alianza del pacífico

Este documento indaga sobre los determinantes que hicieron posible la creación de la Alianza del Pacífico. Para ello, se describen elementos del contexto internacional y regional dentro del cual se gestó la Alianza, y que permitió la convergencia de unos intereses afines entre Chile, Colombia, Perú y México que, determinados por identidades similares, desembocaron en un proyecto colectivo: La Alianza del Pacífico. El argumento principal es que los intereses, las características y las identidades comunes configuraron unas preferencias nacionales que fueron materializadas en la creación de un proyecto de integración económica con características particulares, que sirve de plataforma para la coordinación, la articulación, la inserción y el desarrollo económico de sus miembros.
