Aristotle University of Thessaloniki Library & Information Centre: A new-old library

The Aristotle University of Thessaloniki Library and Information Centre (AUTh Library) is a rather new library, 90 years old. Yet, its collections go back till the 10th century AD thanks to donations by professors, donors and other benefactors. This paper shortly presents the history of the AUTh Library

Elementos para una transposición didáctica del concepto de derivada "La derivada de carathéodory"

Este trabajo se inscribe en la línea de investigación «Formación matemática en contextos curriculares y pensamiento matemático avanzado», de la maestría en Educación énfasis en Educación Matemática del Instituto de Educación y Pedagogía de la Universidad del Valle y se refiere a la transposición didáctica de los conceptos fundamentales del cálculo y la problemática que plantea la prevalencia de la comprensión algorítmica o instrumental sobre la comprensión conceptual. Se relaciona con investigaciones ya realizadas como las de Delgado (1998), Campaña (2009), Álvarez (2011) y tiene como objetivo central aportar elementos para caracterizar una transposición didáctica asociada al concepto de derivada utilizando la definición de Carathéodory que se fundamenta en el concepto de continuidad sin recurrir al paso al límite. Se considera que, si bien la construcción del concepto de continuidad ¿-¿, en un primer curso de cálculo del nivel universitario, implica la superación de múltiples obstáculos cognitivos (ver Delgado, 1998), ella es necesaria para fundamentar los conceptos del cálculo y de esta manera acceder al concepto de derivada, propiciando la superación de la comprensión típicamente algorítmica que ha venido caracterizando el aprendizaje de este concepto entre estudiantes universitarios. El marco teórico, constructivista radical, define el campo conceptual para examinar una posible transposición didáctica de los conceptos fundamentales del cálculo, centrados en el concepto de continuidad y la derivada de Carathéodory apoyándose en la epistemología genética de Jean Piaget, el concepto de obstáculo cognitivo ¿de origen epistemológico, ontológico, didáctico o sociocultural¿ transpuesto de la epistemología a la didáctica por Guy Brousseau (1983, 1989) y la teoría sobre estructuras teórico conceptuales. Como resultados principales de este proyecto se caracteriza una Estructura Teórico Conceptual (ETC), asociada con el concepto de derivada utilizando la definición de Constantin Carathéodory. (1954) y principalmente se muestra la potencialidad de esta definición en la flexibilidad del currículo.MaestríaMAGISTER EN EDUCACIÓN - ÉNFASIS EN EDUCACIÓN MATEMÁTIC

Building Sovereignty in the Late Ottoman World: Imperial Subjects, Consular Networks and Documentation of Individual Identities

This dissertation examines the formation of Ottoman sovereignty in the nineteenth and early twentieth centuries at the disciplinary intersection of international law and history. As an attempt to break away from a strictly territorial understanding of sovereignty as a fixed legal construct, it explores shifting definitions of sovereignty within and across the boundaries of the Ottoman Empire as well as its semi-autonomous provinces. It argues that Ottoman sovereignty was constantly re-defined by inter-imperial rivalries, jurisdictional politics and the formation of modern subjecthood and citizenship in the emerging arena of international law during the period in question. Exploring what it meant to be an Ottoman and a foreigner in the Ottoman Empire during this period, I argue that subjecthood; nationality and citizenship often appear as instrumental categories incidentally utilized by ordinary individuals when deemed necessary. A careful examination of the Ottoman passport regime, on the other hand, proves that there already existed a prolonged process of experimentation on individual documentation and movement controls during the second half of the nineteenth history. Studying a collection of identity cards and passports, I argue that individual documentation mattered more for some subjects than others, who needed to maintain and negotiate their identities under overlapping structures of multiple sovereignties. A careful analysis of various case studies, from former Ottoman Bulgaria to never-Ottoman Dutch Indonesia, demonstrate that disputed claims to nationality and foreign protection in one locality were often connected to the enhancement or loss of Ottoman sovereignty elsewhere and can only be understood beyond the geographical and disciplinary constraints of area studies

VARIATIONAL PROBLEMS INVOLVING NON-LOCAL ELLIPTIC OPERATORS

My thesis deals with nonlinear elliptic problems involving a non-local integrodifferential operator of fractional type. Our main results concern the existence of weak solutions for these problems and they are obtained using variational and topological methods
