In the present paper will be presented to the reader how systemics and cybernetics are useful to structure a Systemic-Cybernetic Theory of Law (SCTL). By means of SCTL it will be possible to give an answer to diverse Philosophy of Law's questions, obtaining in this way a more complete vision of Law in comparison with others that have been offered. It will be exposed how the methodology and the systemic and cybernetic epistemologies enter into the juridical world, then there will be enumerated some characteristics of a possible SCTL and the answer that this new vision of Law offers for the juridical questions. The SCTL will constitute - we expect - the paradigm that the complexity of the topics and systems of (national, international, transnational, etc.) law requires to confront the crisis of its practical operation and of its scientific and philosophical researches.

Modeling and forecasting exchange rates is a big economic headache. This paper uses an artificial neuronal network model to represent the Colombian real exchange index dynamics because it describes the series dynamics better than a self-regressive linear model does, as may be appreciated in the result of the verosimilitud radius contrast. The model was accepted after applying a series of standard tests and contrasting the results against those obtained using a self-regressive linear model. The results indicated that the current value of a series solely depends on its previous value. [ABSTRACT FROM AUTHOR]
