Building a peaceful way for constructing a culture of peace with colombian children = Construyendo una forma pacífica de construir una cultura de paz con niñas y niños colombianos

Por: María Camila Villar Guhl | Fecha: 2011

Colombia is a country that is afflicted by violent conflict. Nowadays many Colombians suffer as a result of it, especially children who are directly affected, either physically or emotionally. Peace education is a very effective tool for change, thus enables people and communities to start building processes of change together. Children are the present and future of any country and so working with them is a constructive way to start processes of change. In order to help change the current violent situation in Colombia, an intervention for building a culture of peace with Colombian children through playful interactions has been created. Taking into account the results and successes of previous research carried out by Villar-Guhl (2007), it has been possible to continue using games and activities as vehicles to work with children for peace. By doing so, it has been possible to develop a new way of empowering children, by encouraging critical thinking about their current situation in order to help them to raise their voices and participate in building a new and positive future for themselves and their communities. This intervention is a tool that starts the work of changing the current culture of violence in Colombia, hence beginning the process of transforming it into a culture of peace.

Una investigación sobre crítica política de representación y estudios culturales: representación de la violencia en Colombia = A research on political critique of representation and cultural studies: representation of violence in Colombia

Por: Pedro Fernando Cruz Ángel | Fecha: 2011

La presente investigación es un trabajo que pretende hacer un acercamiento a la crítica política de la representación mediante un estudio de casos de sujetos pertenecientes al contexto social de Colombia. La construcción del presente escrito esta guiada por los estudios culturales enfocados en la cultura visual, por la teoría crítica y a través de una indagación de tipo narrativo. Como referente tomado desde la cultura visual se trabajó con diez obras de las cincuenta que componen la colección: ‘Violencia en Colombia’ (2004) del artista Fernando Botero. Como sujetos participantes del estudio en mención se trabajó con tres grupos familiares colombianos. Las preguntas de investigación entorno a las cuales gira esta disertación son: ¿De qué forma(s) se asume la situación social de la violencia en Colombia desde el problema de la crítica política de la representación? y además ¿Cómo se relaciona cada sujeto participante en este estudio con este aspecto desde su propia cotidianidad y en relación con las dinámicas de las relaciones sociales?

Sensing otherness: a media archeology approach to touch and interaction design

Por: Eliana Corredor Tobón | Fecha: 2013

Since the last two decades, touch as a sense that could be extended by means of technology has become a major topic for interaction design.The following Thesis examines how touch has been approached by Digital Media and specifically by Interaction Design the last decades. Following this exam there appears to be two main ways in which touch is offered and narrated: Either as Haptic interactions which mention touch as the possibility of simulating Closeness and Intimacy, or as Tangible interactions where touch becomes critical, subversive or monstrous as it opposes to other inmaterial digital media. By a media archeological methodology of finding Topos (cliches or recurrent narrations that spread and repeat in time and different cultures), both strangeness and intimacy as narrations of touch within interaction design were analyzed from the perspective of a ‘tactiloclasm tradition’ in western culture and the return of touch as the ‘other’. Touch as closeness and intimacy, a narration which often appears in Haptic screen-based interactions, was found connected to tactiloclasm as it presents a private and pleasurable immaterial touch that is clean and free of any co-implication: touch is black boxed. By the other hand, the narration of Touch as strangeness, which often appears in Critical Design and Digital Fabrication, was found connected to a nostalgia for a supposed primitive fetishistic touch: touch returns in digital media as strangeness, monstrousity, criticality or subversiveness. As a proposal to confront these two recurrent narrations, the second part of this Thesis presents the idea of a design inquiry and the construction process of 5 smart phone cases that materialize the fat traces left by the users on the screens of their devices. The cases intend to open the black box of hidden haptic touch and confront into what we consider monstrous in touch relations. The co-implication of humans and artifacts is embodied.

Imagen de apoyo de Borel Cardinality of Lascar Strong Types = Cardinalidad de Borel de los tipos fuertes de Lascar

Borel Cardinality of Lascar Strong Types = Cardinalidad de Borel de los tipos fuertes de Lascar

Por: Esperanza Buitrago Díaz | Fecha: 2014

A Strong type is a class of a bounded equivalence relation (i.e. the quotient is a proper set) on tuples of the monster model of a complete theory T. Today, there are three different notions of strong types: a Shelah’s strong type is a class under the smallest definable equivalence relation on the monster model C with finite classes; a Kim-Pillay strong type is a class of the least bounded type-definable equivalence relation kp, in fact, this type may be characterized as the finest notion of strong type for which the corresponding quotient is a compact Hausdorff space when it is equipped with the so-called logic topology; finally, a Lascar strong type is simply a class of the smallest equivalence relation ls, which is bounded and invariant under automorphisms. For some years, it was an open problem to find an example of a theory for which the Kim-Pillay and the Lascar strong type do not coincide. After finding such example, it was suggested that Lascar strong types could be described from the point of view of Decriptive Set Theory, in particular of quotient of Polish spaces by Borel equivalence relations. Furthermore, it was conjectured that for every tuple a of the monster model, if [a]ls = [a]kp, then [a]kp restricted to [a]ls is nonsmooth, using the so-called Silver dichotomy. Despite the Stone space is not always Polish, the authors proved such conjecture distinguishing the case when the theory is countable -in which case for any countable model M of T, S(M) is Polish- and when it is not. My Master’s thesis consists in filling up all the details for both cases, specially for the case when T is countable. Given a complete first order theory T, its monster model C has none topological structure. Nevertheless, given a model M of T, the Stone space S(M) has it, this is, it is well known that it is Hausdorff, that given any formula ', the set of [ ] determines a basis of clopens, etc.

Assessing the ground truth drivers of land cover and land use changes at a local scale in Cundinamarca and Tolima Departments in Colombia

Por: Sergio David Cortés Alonso | Fecha: 2012

The land use and land cover change is a problem which affects mostly tropical developing countries such as Colombia. Drivers of these changes are both direct and indirect, and exogenous or endogenous and include agricultural expansion, deforestation, climate change, and national and international policies. Drivers are divided according to the grade of expansion and the level of influence on the land. This project proposal evaluated the uses of the land in Colombia, the constraints, land cover, farming distribution, and permanent crops and arable land, by percentage of intensity. Two specific sites were chosen in the departments of Cundinamarca and Tolima by using Terra-i software which identified the land cover and habitat change in real time every sixteen days from 2004 to 2011. The cover and uses of the land for each site are described along with the conflicts in the uses of land. In order to fully understand the issue, both the drivers and the causes of land use and land cover are given, in addition to case studies and photographs. The data was analysed in the field qualitatively through direct interviews to communities in both sites to verify information given by Terra-i. The results focus on the changes in the land use produced by increasing industrialization and overexploitation of the land. Drivers in the land use change are divided into demographic, institutional and technological development, and global environmental change conditions.

Materiau et forme pour rien essai critique sur l'architecture et la notion de dispositif

Por: Pablo Andrés Gómez Granda | Fecha: 2015

This Ph.D thesis examines and discusses the notion of dispositif (device) such as it emerged within the contemporary French philosophy, mainly in Michel Foucault's and Gilles Deleuze’s works. Its intention is to criticize the association in architecture of the structural and the organization, to propose an architectural practice less dedicated to the assemblages of environments, but which facilitates situations of freedom. For that purpose, this thesis studies the notions of form and function in architecture from a philosophical order reasoning on the ""material"". Three moments of a possible history on the material are considered. In the first two moments, dedicated to the concrete, and ""smart"" materials respectively, architecture appears in its connection to a mode of the industry and to a labor economy. In the third moment, it is shown how the staging and fiction can contribute to transforming materials into dispositifs. On this base, we move, on the one hand, to strip the notion of form from the functional significations that surround it, while on the other hand, we put in tension Michel Foucault's reading proposed by Giorgio Agamben, putting into context the concepts and the suggestions implied in it, in regards to economy. All this work is indissociably architectural and philosophical. Its purpose is to establish the essential character, for both domains of thought, of the notion of an aimless form or “form for nothing "". This notion can be related to an architecture of the ""discontinuity"" whose materials are neither in harmony with the structure nor the power of the dispositifs.

Effect of microbial typology in the energy production through Microbial Fuel Cells (MFCs) = Efecto de la tipología microbiana en la producción de energía en Celdas a Combustible Microbianas (MFCs)

Por: Ana María Valencia López | Fecha: 2011

The Microbial Fuel Cells allow the direct conversion of chemical energy, contained in different substrates, into electric energy. A typical MFC consists of two compartments, anode and cathode separated by a Proton Exchange Membrane (PEM). In the anodic compartment the oxidation of the organic waste takes place, while the electron acceptor is reduced in the cathodic compartment. Forcing the electrons passage through an external circuit and thanks to the protons transport between both compartments, it is ensured the maintenance of the charge balance inside and the electric circuit is closed. The main purpose of this study has been to evaluate the performance, in terms of the power (P; mW/L, mW/ m2) and the Open Circuit Voltage (OCV;V), of a laboratory scale MFC to vary the microorganisms type which have the task of extracting the electrons from the substrate and carry them to the anode. In addition, the effects of the use of a redox mediator have been evaluated, which would allow a reduction on the anode overpotential. It was finally carried out the cell scale-up with the goal of identifying the parameters that mostly influence the performance of the system.The microorganisms used as biocatalysts in this study have been divided in three groups: - Brewer’s yeast, Saccharomyce cerevisiae - Acetogenic bacteria pretreated at pH 3 - Microorganisms present in seawater With the brewer’s yeast, the effect of varying its concentration on the MFC performance has been studied, noting that, with the growth of this parameter, the power density of the cell increases. In these tests it was used the methylene blue as an electronic carrier and has been verified that when the carrier/microorganism ratio is lower, the performance is better. Regard to the microorganisms in seawater, some tests have been carried out to determine the influence on the MFC performance of several factors, such as; the storage of the samples at low temperature (test A2 and A4), the change of the inoculum concentration on the anode chamber (test A3), the use of inoculums enriched through successive growths (Test A7 and A8), the absence of electronic carrier on the electron transport to the anode and, as a consequence, on the power density obtained (Test A5, A6, A7 and A8). Finally it has been analyzed the effect of the scale-up and the recirculation conditions of the electrolyte solutions on the MFC performance (Test A9).

Ethical considerations for the transposition of health policies: Human body parts donation policies = Consideraciones éticas para la transposición de políticas de salud pública: políticas para la donación de órganos

Por: Diego Alejandro Peña Restrepo | Fecha: 2011

The gap between organ donors and organ recipients is a worldwide problem that has been set in national agendas around the world. However, there has not been a clear pathway to establish a standard universal guideline to deal with organ transplantation and its related processes. This paper argues through an exhaustive literature review on ethics and bioethics that the difficulty for having such system are varying conceptualizations of world health as well as the difficulty of imposing a universal ethics code.  The paper has three core parts. Part I is a theoretical view of the Human Body Parts (HBP) transplantation procurements through the optics of ethics and religions. Part II is the empirical view of those issues through legal frameworks. While part III deals with the ethical considerations of transposing a health policy in a pluralistic society. This paper finds that: (1) Cultural and religious beliefs of the general public cannot be ignored when transposing health policy. (2) Bioethical traditional approaches to organ donation have a limited scope when dealing with existential or religious problems. (3) When comparing bioethical principles solidarity showed to deal with a wider spectrum of ethical problems as compared to autonomy. (4) Having a universal guideline to deal with organ transplantation isn’t impossible; however, differences in the founding principles of global health ethics are the biggest obstacle.

Counterinsurgency lessons from colombia: an assessment of the colombian army transformation from 1998 to 2010

Por: David Andrés Rodríguez Camacho | Fecha: 2014

This thesis offers an account of how the Colombian Army recovered from a series of humiliating defeats inflicted upon it by illegal armed groups led by the Revolutionary Armed Forces of Colombia (FARC) in the 1990s. It explains how a combination of internally generated, bottom-up and top-down organizational innovations, U.S. security assistance, and dynamic management from President Alvaro Uribe and a civilianized Ministry of Defense was able to restore Colombian Army morale, and to restructure and reorganize the military into an offensive force able to gain battlefield dominance and restore government authority over a greater part of the national territory.

Resisting Through Corporate Values = Resistiendo a través de los valores corporativos

Por: Óscar Hernán; Yuzenho Ismarson Vargas Villamizar | Fecha: 2010

Purpose: To denaturalize the concept of corporate values as a necessary managerial practice to engineer culture in organizations and to explore how its enactment influences power - resistance interplays and the workplace construction of selves. Method: We engaged in Critical Management Studies (CMS), using an interpretative approach to our empirical material. Theoretical framework: The study is based on the concepts of organizational control, corporate values enactment, workplace resistance and construction of selves. Empirical Foundation: The empirical data was gathered based on a triangulation method by employing qualitative interviews, analysis of corporate material and fieldwork observation in Asian Monetary Fund, an Indonesian financial institution headquartered in Jakarta. Conclusion: We found that corporate values is a fragmented, fluid and fragile concept which can be used by employees to reproduce, rationalize and transform power relations in the organization and this process to resist “through” rather than “against” corporate values affects the construction of selves at work; producing individuals who simultaneously identify and dis-identify to the organization.
