How Will Sustainability Transform Democracy? Reflections on an Important Dimension of Transformation Sciences

How Democratic Will E-Democracy Be?

Recent developments (e.g., e-Government, e-Democracy, e-Voting, etc.) of the Information Society expose the limits of system security. The ubiquitousness of Information Technology relies on stringent system requirements. Although new technology addresses technical problems and provides new challenges, new technology often gives rise to new hazards. In order to identify mitigation actions, it is...

How Non-linearity will Transform Information Systems

One “problem” with the 21st century world, particularly the economic and business worlds, is the phenomenal and increasing number of interconnections between economic agents (consumers, firms, banks, markets, national economies). This implies that such agents are all interacting and consequently giving raise to enormous degrees of non-linearity, a.k.a. complexity. Complexity often brings with i...

An Adaptive Segmentation Method Using Fractal Dimension and Wavelet Transform

In analyzing a signal, especially a non-stationary signal, it is often necessary the desired signal to be segmented into small epochs. Segmentation can be performed by splitting the signal at time instances where signal amplitude or frequency change. In this paper, the signal is initially decomposed into signals with different frequency bands using wavelet transform. Then, fractal dimension of ...

How to test for debt sustainability? Some theoretical reflections on an empirical test

Testing the reaction of the primary surplus to variations in public debt, relative to GDP respectively, has been frequently resorted to in order to test for sustainability of a given debt policy. In this contribution, we analyze theoretically under which condition a positive reaction of the primary surplus to variations in debt implies a sustainable debt policy. We demonstrate that the evolutio...
