In this thesis we consider different tests for unit roots in the presence of structural change. We present the theory that lies behind unit roots, what we mean by structural change and try to detect the instances that “breaks” occur in the data. When performing a unit root test, when there is a structural change the results are biased toward accepting a unit root. Therefore, special care must be t

Abstract in SpanishPresentamos en este artículo los fragmentos de la primera traducción completa conocida del Corán, acompañados de una introducción y notas. Esta traducción al griego, realizada algún tiempo antes de 780 d.C., no ha sido hasta ahora reconocida en los estudios coránicos ni en los bizantinos, sin que sus principales rasgos hayan sido advertidos. En el artículo argumentamos que la tr

The universalistic understanding of the subject embedded in the Liberal and Marxist traditions together with contrasting accounts of unconstrained agency fail to explain the contingencies of ground responses that call for social change. The paper makes a case for the opening of the understanding of the human subject when placed in the theoretical terrain of radical political philosophy elaborated

Ground deformation monitoring is one of the main geoindicators that should be considered to assess volcanic hazard. Satellite earth observation data and Synthetic Aperture Radar (SAR) interferometry have been used continuously since 1992 to measure or study the temporal evolution of surface deformation in volcanic areas in conjunction with ground-based geodetic measurements. Such methods were app

This study explores the contexts in which the conflict evolved and how history was perceived, narrated and used by institutions, communities and individuals who sought to influence public opinion and policymakers. The theoretical point of departure is the concept of collective memory, defined as the totality of discourses through which a society makes sense of itself, the present and the future th

It can evaluate an unlimited number of derivatives to a fixed cost relative to the computing time of the original function. The AD technique is used in many fields for large and complex calculations in order to get accurate values of derivatives fast. Banks and other financial institutions handle calculations of

Departing from a critical perspective on intellectual property rights, this article investigates the popular phenomenon of free online file-sharing beyond its hegemonic framing as piracy. The article focuses on the civic potentials entailed in free and participatory culture of new media and ICT. A “civic” focus, in the context of free sharing, aims at assessing the potential of a democratic cultur

The article begins from critical accounts addressing the crisis of politics and citizenship today, to study the civic potential that several media and social scholars view in informal practices that include the usage of new media and information and communication technologies. On one hand, new media and ICT are noted to empower individual users and groups, to provide spaces of voice and debate and
