RACISMO INSTITUCIONAL, VIOLENCIA Y POLíTICAS CULTURALES: LEGADOS COLONIALES Y POLíTICAS DE LA DIFERENCIA EN COLOMBIA
Maya Restrepo,Luz Adriana;
Historia Crítica , 2009,
Abstract: this article is part of a line of thought that i proposed in another article "memories in confict and peace in colombia: discrimination towards blackness and black people", in which i planted the seeds for a study about racism and discrimination towards the descendents of african people in colombia not only as an everyday practice but especially as a long-standing problem tied to the institutional culture of the state. from an historical perspective, this institutional culture has its roots in the colonial legacy of imperial administration and its transformations during the republican period. i suggest that the politics of imperial and colonial difference are still felt in the contemporary colombian state. i also raise various questions about the commitment of intellectuals, historians, and geographers with regard to public policies.
Generación y flujo del ahorro y la inversión: análisis de la coyuntura internacional
Luz Adriana Flórez
Perfil de Coyuntura Económica , 2005,
Abstract: El comportamiento del ahorro y la inver- sión mundial ha cambiado de manera im- portante en los últimos cinco a os. Los ca- pitales excedentes de las economías emer- gentes se han dirigido hacia las economías desarroladas. Este comportamiento está explicado en parte por un choque positivo de productividad en los países emergentes y uno negativo en los desarrolados, ade- más de las diferentes políticas económicas en ambas regiones. En este sentido, el ex- ceso de ahorro de las economías asiáticas, especialmente de China y los países exportadores de petróleo, ha estado finan- ciando una gran parte del consumo de la economía norteamericana. Adicionalmente, este ahorro ha impulsado una fuerte caída en las tasas de interés de largo plazo y un crecimiento en los precios de la vivienda de las economías desarroladas. Los facto- res que han movido estas decisiones de ahorro e inversión mundial no cambiarán fácilmente; de esta manera es probable que los desequilibrios generados por este cam- bio permanezcan por un buen tiempo.
áfrica: legados espirituales en la nueva granada, siglo XVII.

Abstract:
Botánica y Medicina africanas en la Nueva Granada, Siglo XVII.

Historia Crítica , 2000,
Abstract: La relación que los bozales (africanos que llegaban directamente de Africa que no se expresaban en lengua castellana ni conocían la fe católica) y sus hijos nacidos en la Nueva Granada mantuvieron con los vegetales y los animales, en particular las aves, es otro de los legados ancestrales que la nación colombiana le debe a Africa. Los africanos le transmitieron a sus descendientes saberes y técnicas sobre el mundo vegetal y animal. Estos conocimientos, que fueron utilizados para curar los males del cuerpo y los del alma, se caracterizaban por un componente experimental cuyo éxito dependía también de la interacción con los espíritus. De ahí que el Tribunal de la Inquisición de Cartagena hubiera juzgado a los africanos y a sus hijos en calidad de "brujos(as)", "hechiceros(as)" y "curanderos(as)".

THE ETERNAL RETURN TERRITORY
Luz Adriana Henao Quintero
Luna Azul , 2006,
Abstract: The new dynamics, which have arisen in the context of globalization, are transforming cultures and their relationships, productive and commercial activities, territorial vision and its management. This situation is due to the incorporation of strategies and activities which are more immaterial and impersonal by the day. It is not possible to deny that global effects and their virtual technological platforms are crossing urban and rural environments indistinctively, using a totalizing and uniting effect in which communications are the instrument and the means to integration or, perhaps, disintegration. This new global cultural perspective with the resulting influence of the media will change individual perceptions and will modify social relationships in communities and territories. Rural territory doesn’t escape this new global dimension, alternative functioning structures will penetrate every day activities, and country culture, its activities and times, will undoubtedly be transformed. The traditional farmer and his space—time relationship which historically has meant the “Eternal Return” time will possibly end or, at least, suffer notable transformations. Time in the rural environment, usually cyclic, in which day by day beginning to end are united, will be altered by the penetration and action of this new paradigm. The only thing left is just to consider the opportunities and challenges that emerge from this new scenario, as well as obtaining all of their potential in order to find their sustainability
Hyperbolic sets that are not contained in a locally maximal one
Adriana da Luz
Mathematics , 2013,
Abstract: In this paper we study two properties related to the structure of hyperbolic sets. First we construct new examples answering in the negative the following question posed by Katok and Hasselblatt. Let $\Lambda$ be a hyperbolic set, and let $V$ be an open neighborhood of $\Lambda$. Does there exist a locally maximal hyperbolic set $\widetilde{\Lambda}$ such that $\Lambda \subset \widetilde{\Lambda} \subset V $? We show that such examples are present in linear anosov diffeomorophisms of $\mathbb{T}^3$, and are therefore robust. Also we construct new examples of sets that are not contained in any locally maximal hyperbolic set. The examples known until now were constructed by Crovisier and by Fisher, and these were either in dimension bigger than 4 or they were not transitive. We give a transitive and robust example in $\mathbb{T}^3$. And show that such examples cannot be build in dimension 2.
Characteristics of Blended Learning Environments: Case Study of a Postgraduate Programme in Los Andes University
Luz Adriana Osorio Gómez
Revista de Universidad y Sociedad del Conocimiento , 2010,
Abstract: Hybrid learning environments combine presential teaching and virtual classrooms, which use information and communication technologies. This definition is based on the desire to combine and bring together two models of teaching-learning: the traditional system of face-to-face learning and the e-learning system, maintaining the possibilities offered by each one. The aim of this article is to present the main results of a study to identify the characteristics of hybrid learning environments, which should be taken into account in their design and development. The research consisted of a case study of a hybrid postgraduate course taught at the University of Los Andes. An analysis was carried out on the set-up of the ten subjects of the course and on the impressions of students and lecturers throughout the programme which ran during the second half of 2006 and the first half of 2007. This approach allowed the identification of a teaching-learning proposal that was very positively rated by the lecturers and students that took part in the process. They all agreed that the learning objectives of the individual subjects and the programme as a whole had been achieved. Data were compiled using qualitative techniques (interviews, observation of physical and virtual classrooms) and quantitative techniques (surveys). The analysis of the results led to the identification of a series of characteristics of the hybrid model which could contribute to the general understanding of blended learning environments.
Sistema morfológico casual en la lengua wounan
Luz Adriana Arboleda Vásquez
Boletín de Antropología , 2009,
Abstract: Este artículo muestra la interdependencia del verbo y los participantes. Se ilustra la relación sistemática que existe entre la morfología propia del nombre y su capacidad de incorporación de personas en el verbo. La investigación fue realizada desde la etnociencia y la lingüística descriptiva, lo que permite hacer una valoración gramatical de la lengua pero desde la apropiación que los hablantes tienen de ella en la actualidad, por tal razón hablamos de un estudio sincrónico. El conocimiento de este campo desde la perspectiva etnocientífica aporta elementos de juicio para la apertura, discusión y construcción de currículos y propuestas pedagógicas cuyos contenidos temáticos incorporen la manera "propia" de ver e identificar el mundo.
On the free time minimizers of the Newtonian N-body problem
Adriana da Luz,Ezequiel Maderna
Mathematics , 2013, DOI: 10.1017/S0305004113000650
Abstract: In this paper we study the existence and the dynamics of a very special class of motions, which satisfy a strong global minimization property. More precisely, we call a free time minimizer a curve which satisfies the least action principle between any pair of its points without the constraint of time for the variations. An example of a free time minimizer defined on an unbounded interval is a parabolic homothetic motion by a minimal central confguration. The existence of a large amount of free time minimizers can be deduced from the weak KAM theorem. In particular, for any choice of x0, there should be at least one free time minimizer x(t) defined for all positive time and satisfying x(0)=x0. We prove that such motions are completely parabolic. Using Marchal's theorem we deduce as a corollary that there are no entire free time minimizers, i.e. defined on R. This means that the Ma\~n\'e set of the Newtonian N-body problem is empty.
