School has evolved from a place where knowledge is provided to a place where learners are helped to develop their professional and social skills. Consequently, education must evolve through big challenges in order to face the changes of society in the XXIst century

Different procedures to obtain atom condensed Fukui functions are described. It is shown how the resulting values may differ depending on the exact approach to atom condensed Fukui functions. The condensed Fukui function can be computed using either the fragment of molecular response approach or the response of molecular fragment approach. The two approaches are nonequivalent; only the latter approach corresponds in general with a population difference expression. The Mulliken approach does not depend on the approach taken but has some computational drawbacks. The different resulting expressions are tested for a wide set of molecules. In practice one must make seemingly arbitrary choices about how to compute condensed Fukui functions, which suggests questioning the role of these indicators in conceptual density-functional theory

The computational approach to the Hirshfeld [Theor. Chim. Acta 44, 129 (1977)] atom in a molecule is critically investigated, and several difficulties are highlighted. It is shown that these difficulties are mitigated by an alternative, iterative version, of the Hirshfeld partitioning procedure. The iterative scheme ensures that the Hirshfeld definition represents a mathematically proper information entropy, allows the Hirshfeld approach to be used for charged molecules, eliminates arbitrariness in the choice of the promolecule, and increases the magnitudes of the charges. The resulting "Hirshfeld-I charges" correlate well with electrostatic potential derived atomic charges

L'objectiu d'aquesta tesi doctoral és analitzar el llegat jurídic de Ramon Martí d'Eixalà, especialment els seus manuals de dret mercantil i dret civil. En aquest sentit, cal recordar que Ramon Martí d'Eixalà va viure en el segle XIX, moment en el qual s'havien iniciat una sèrie de canvis econòmics i socials profunds. El seu manual de dret mercantil, Instituciones de derecho mercantil de España fou molt més reconegut que el Tratado elementar del derecho civil romano y español. Doncs, el manual de dret mercantil fou recomanat com a llibre de text pels estudis de Jurisprudència durant varis anys, mentre que el manual de dret civil mai va formar part del llistat de manuals elaborat pel govern. A més, la filosofia britànica ocupa una part important de la investigació, ja que Ramon Martí d'Eixalà coneixia el pensament britànic i va introduir la filosofia del sentit comú a Catalunya.

The subject matter of the analysis conducted in the text is information and anti-terrorist security of Poland, which has been presented within the context of a clash between two spheres – the state and the private sphere. Furthermore, the issues of security have been supplemented with a description of the tasks and activity of the Internal Security Agency, as well as a synthetic appraisal of a terrorist threat to Poland. The main parts of this work are concerned with: (1) the state and the private sphere, (2) " terrorism " and terrorist offences, (3) the tasks and activity of the Internal Security Agency, (4) an appraisal of a terrorist threat to Poland. Given the necessity to elaborate the research problem, the text features the following research questions: (1) To what extent does referring to a threat to security influence a limitation on rights and freedoms in Poland (with regard to the clash between the state and the private sphere)?, (2) To what extent do the tasks and activity of the Internal Security Agency influence the effectiveness of anti-terrorist security in Poland?

The thesis which follows, entitled ''The Postoccidental Deconstruction and Resignification of 'Modemity': A Critical Analysis", is an exposition and criticism of the critique of occidental modemity found in a group of writings which identify their critique with a "postoccidental" point of view with respect to postcolonial studies. The general problem ofthe investigation concems the significance and reach ofthis critique of modemity in relation to the ongoing debate, in Latín American studies, about the historical relationship between Latín America, as a mu1ticultural/ structurally heterogeneous region, and the industrial societies of Euro pe and North America. A brief Preface explains the genealogy of the author's ideas on this subject Following this preface, the thesis proceeds to analyze the writings in this corpus through an intertextual, schematic approach which singles out two rnajor elements of the postoccidental critique: "coloniality" and "eurocentrism". These two main elements are investigated in the Introduction and Chapters One and Two, in terms of how they distinguish postoccidental analysis from other theoretical tendencias with which it has affinities but whose key concepts it reformu1ates in ways that are key to the unique approach which postoccidental analysis takes to modemity, the nature of the capitalist world system, colonialism, subaltemization, center/periphery and development . Chapter Three attempts a critical analysis of the foregoing postoccidentalist deconstruction according to the following question: to what extent does it succeed in deconstructing "modernity" as a term which refers to a historically articulated set of discourses whose underlying purpose has been to justify European and North American hegemony and structural asymmetries vis-a-vis the peripheries of the capitalist world system, based on an ethnocentric, racialist logic of exploitation and subalternization of non-European peoples? A Conclusion follows Chapter Three.

The present paper offers a fresh perspective from the South about the relevance of progressive Latin American public health (termed ‘collective health’) by highlighting a number of its hard scientific contributions which, unfortunately, remain almost unknown to mainstream medical and public health researchers outside Latin America. An armed form of structural greed has now placed the world on the brink of destruction. At the same time, however, fresh winds blow in the continent. This paper is an invitation to confront the menacing forces producing our unhealthy societies and an opportunity to form fraternal partnerships on the intercultural road to a better world, where only an epidemiology of dignity and happiness will make sense.
