The theater in television. The theater for television. An production proposal = El teatro en televisión. El teatro para televisión. Una propuesta de realización

Por: Erik Leyton Arias | Fecha: 2005

El teatro en televisión ha sido injustamente tratado (en el mejor de los casos) o francamente olvidado. Cuando aparecen imágenes teatrales en la pantalla chica, éstas son terriblemente aburridas, faltas de diseño, faltas de originalidad, y divorciadas de cualquier consideración de lo que el “entretenimiento televisivo” implica (alejándonos, claro, de la trivialización y vulgarización que hace la televisión a diario, y refiriéndonos mejor a las potencialidades del espectáculo televisivo cultural). El teatro es un mundo complejo, diverso, concreto y dinámico. Y como tal, es susceptible de ser tratado con imaginación, originalidad, creatividad y gracia en televisión, tal como ha sucedido con otras artes similares, como la música, para no ir más lejos. La tesis se pregunta por las estrategias teóricas, técnicas y de producción que el realizador debería esgrimir para llevar cualquier tipo de espectáculo escénico a la televisión, respetando la naturaleza de los dos medios, considerando la realidad de la producción en televisión, aludiendo a una traducción de lenguajes, y pensando siempre en la creación de un objeto audiovisual de importancia estética, plástica y televisual.

The thorns of Colombian violence: 60 years of constructing national identity = Las espinas de la violencia en Colombia: 60 años construyendo identidad nacional

Por: Maria José Montaña Correa | Fecha: 2013

El tema de la violencia en Colombia ha sido retomado en multiples ocasiones desde diferentes perspectivas. En este caso se hace un análisis de la violencia generalizada en Colombia, desde el punto de vista de un fragmento de la población identificado como “migrantes internos.” En el texto se estudia la relacion entre la violencia y el sentido de idetidad nacional de migrantes internos hoy residentes en la ciudad de Bogotá.Con este fin se hace un análisis histórico de la violencia que ha tenido lugar los últimos 60 años en el territorio colombiano, el cual se conecta con el posterior análisis de algunos de los elementos que componen la identidad nacional colombiana.

A Framework For The Managemente Of The Biodegradable Waste In Bogotá-Colombia = Un Marco Para El Manejo De La Basura Biodegradable En Bogotá-Colombia

Por: Adriana Lizette Gutiérrez Bayona | Fecha: 2014

Waste management is one of the growing problems in many highly populated cities around the world, and the amount of strategies designed to solve it has changed during the last decade. It passed from land filing to incineration and mechanical biotechnology; this quick change was partially induced by the threat that garbage is for the environment, and later on by the acceleration of climate change, since the public services industry was bound to comply with the emissions reduction targets. The newest technologies are being applied in Europe and North America, giving them a new way to face their waste issues. However, the industrialized States are not the only ones with these concerns, in the developing countries, it is a matter that is becoming an structural problem, because of the population growth and the dynamics of the capitalist practice; moreover, it is difficult to solve due to low budget or lack of knowledge on the topic. In Bogotá D.C, waste management became one of the most controversial topics due to the many problems presented during the implementation of the Zero-Waste program and the past administrative issues with the Landfill Doña Juana that led to many health and land predicaments for the population. As a consequence, this dissertation seeks to create a new strategy to fix the gaps of the original policy, by designing five time-limited specific objectives, a reform to the segregation strategy and proposing the construction Anaerobic Digestion plant as the best solution for the sustainable control of bio-waste. Therefore, this work will show throughout all the chapters the background of the waste management system, the new strategies to be taken into account by the local administration, the advantages of the AD technology and the possible financing channels for the renovation of the Basuras- Cero Policy. All the information above will be use to conclude, that for the case of Bogotá D.C, the use of bio-waste as a new energy source will strengthen the recycling industry (with the establishment of a better segregation system and the construction of and AD plant) reduce the amount of waste sent to Landfill and decrease GHG emissions; and even though it is a small step, it can become the foundation for fixing some weaknesses of the economic system and some social mores.

Music: from a cultural good to an object of consumption

Por: Laura Bermúdez Espinosa | Fecha: 2012

The illegal downloading of music issue has been studied during the last decade due to the negative impact that it has had into the music industry. However most of these studies have focused on analyzing the consequences of this act in legal and economic terms. This study focuses on analyzing the cultural, social, psychological and ethical factors influencing UK students´ music consumption of nowadays. Overall, the findings suggested that although technological advances have brought great benefits to both consumers and companies, it has also brought bad habits of consumption, contributing in the transformation of music from a cultural good to an object of consumption. This work analyze the current consumer behavior about music, the extent to which the internet affects individual's ethical and moral values within the consumption of music and finally the effects this issue has brought to the production of culture.

Imagen de apoyo de  Organic photodetectors = Fotodetectores organicos

Organic photodetectors = Fotodetectores organicos

Por: Caterin Yojana Salas Redondo | Fecha: 2014

Organic semiconductors are used in many fields of photonics. Displays fabricated using organic light emitting diodes (OLED) can be found in modern smartphones and tablets, whereas organic solar cells (OPV - organic photovoltaics) are emerging with demonstrated efficiencies above 10%. Organic photodetectors (OPD) are another very interesting domain, with ultrathin active layers (order of tens of nanometers) providing performance comparable to bulk inorganic devices. Thanks to a multitude of possible compounds, parameters such as response spectrum, cut-off wavelength etc. can be easily tuned. Because of very high absorption coefficient and low refractive index, issues such as crosstalk or reflection can be minimized. Another exciting feature is the low processing temperature and thus feasibility of using a flexible foil as substrate, leading to rollable or curved photodetector arrays.The performance of organic based photodetectors has grown considerably in the recent years in terms of high speed, high frequency response and detectivity so as to match the required custom specifications for practical applications such as imaging. However, further attention needs to go towards the understanding of the effects of scaling during miniaturization of these devices, while looking for the preservation and/or optimization of their opto-electrical properties. Therefore, in this thesis, emphasis is given on the photodetectors based on organic conjugated polymer materials for imaging applications. These organic photodetector devices normally suffer from a perimeter-to-area dark current density scaling, hence, special attention is on the understanding of this scaling effect as well as optimization of the fabrication process in order to get low leakage (dark) current, and therefore, large dynamic range of the OPDs. Photodetectors with different geometries and sizes from 0.08 cm2 down to 1.95E ?5 cm2 were fabricated, using two types of edge cover layer. Isolated islands of two different organic films were patterned with photolithography in order to study the dark current mechanisms. Electrical, optical and morphological properties were characterized for both patterned and non-patterned devices. The patterning process used to fabricate the isolated devices does not affect the optoelectrical and morphological characteristics of the photodetectors, and therefore their performance. Moreover, it does not induce or accelerate degradation of the organic films. The dark current density further decreases after full patterning is performed, while preserving all device characteristics. It is proposed to replace the semitransparent edge cover layer by the opaque, if thicker films can be achieved, as it might be possible to decrease the contribution of the perimeter leakage. Once the patterning process is performed, it is possible to implement these isolated devices as photodetectors arrays for imaging applications with an Ion/Ioff ratio of 6 orders of magnitude. It is proposed to perform a theoretical study of the dark current mechanism at the interface between the polymer and the metallic contact edges to model and simulate the perimeter recombination at reverse bias conditions. Moreover, further measurements such as electroluminescent and spectroscopy might aid to characterize the carrier transport in the OPDs. The project was aimed within the R&D department of large area electronics. Moreover, all the fabrication and characterization were performed in the facilities of IMEC.

Imagen de apoyo de  Energy management of a hybrid electric vehicle: an approach based on type-2 fuzzy logic

Energy management of a hybrid electric vehicle: an approach based on type-2 fuzzy logic

Por: Javier Solano Martínez | Fecha: 2012

One of the effects of the globalisation of our society is that people travel more covering longer distances, live far from their work place and consume goods from all around the world. Therefore, it is no coincidence that the transport of people and goods represents more than 25\% of the energy consumption and is one of the principal sources of pollution worldwide. Several efforts must be done to reduce the oil dependence, the energy consumption and the environmental impact of transport systems. In this perspective, the French Army (DGA) has designed and constructed the Electrical Chain Components Evaluation vehicle (ECCE). It is a mobile laboratory to evaluate under real conditions the electric components of Hybrid Electrical Vehicles (HEVs) that reduce the energy consumption and the pollution emission of conventional vehicles. ECCE permits evaluating different energy sources such as batteries, fuel cells, internal combustion engines, ultracapacitors or flywheels. The ECCE project, nowadays in a second phase\footnote{The first phase of the ECCE project is explained in Chapter 1} is developed in joint cooperation with the FEMTO-ST laboratory of the University of Franche-Comté and two industrial partners, HELION and PANHARD General Defense. It aims to study the implementation, control and energy management of different hybrid sources. As a research developed along the second phase of the ECCE project, the principal objective of this thesis is to design, to implement and to evaluate an energy management supervision system in the ECCE HEV. This thesis proposes an original energy management strategy based on expert knowledge and type-2 fuzzy logic. The design of the fuzzy logic controller is done by using knowledge engineering. This technique allows extracting knowledge from several experts using surveys. The consideration of type-2 fuzzy logic systems enables modelling the uncertainty in the answers of the experts. This thesis presents a second application of type-2 fuzzy logic: the voltage regulation of a DC/DC power converter. The principal motivation for developing this application is that it is easier to implement in laboratory at a relatively low cost and it permits a viability evaluation of type-2 fuzzy logic before an implementation in the ECCE mobile laboratory. This is useful because one of the main challenges of this thesis is to reduce the time to experimentally validate the energy management system. This is required to respect the time schedule constraints and to reduce the costs associated to gather the partners of the project at PANHARD locations in Saint-Germain Laval.

Urban wetlands on the edge. A strategic intervention for the recovery of Jaboque Wetland in Bogotá, Colombia = Humedales urbanos al límite. Una visión estratégica para la recuperación del Humedal Jaboque en Bogotá

Por: Juana Marcela Leal Simbaqueba | Fecha: 2012

The global awareness of urban wetlands as areas where crucial issues as urban growth and policies against climate change overlap, must be addressed with critical urgency on developing countries with rapid rates of transformation. The late consciousness about the environmental value of Bogota wetlands have created a rich field of discussion regarding the role of these places in the city, but specially and what constitutes the main purpose of this investigation, the development of a vision which could lead to new kinds of physical interventions between the protected areas and the existing urban settlements. This work aims at recognizing and providing basic principles to guarantee that these physical realities are compatible with the needs of the main natural elements which constitute these ecosystems. Referring to urban ecology principles, wetlands and human settlements are intended as part of the same ecosystem and their reciprocal relations from an urban design perspective is the object of this investigation. The Jaboque wetland, for its size and location, offers interesting conditions to carry on the morphological investigation in order to define series of principles which explore this new physical dimension, and in particular, the construction of concept-plan and master-plan guidelines, aiming at overcoming typical limitations of general and not site-related policies, and finally which could influence actions on other wetlands with similar characteristics.

Measuring sustainability: a systems perspective on sustainability reporting frameworks = Midiendo la sostenibilidad: una perspectiva de sistemas sobre los esquemas de reportes de sostenibilidad

Por: Carlos Oliveros | Fecha: 2010

The paper is a critical revision of the sufficiency of sustainability reporting frameworks to represent sustainability performance. The paper sustains that while frameworks facilitate recording, classifying, and summarizing sustainability data (i.e. economic, social and environmental), they are insufficient to represent organizational sustainability performance. Using Systems Theory and systems proprieties the thesis illustrates how sustainability reporting frameworks fail to sufficiently represent sustainability performance as an organizational management tool.

The emergence of the dutch social enterprise: opportunities for international development cooperation = El surgimiento de la empresa social holandesa: oportunidades para la cooperación internacional al desarrollo

Por: Daniel Gómez González | Fecha: 2012

The international development arena has been transformed in the last two decades. On the one hand, NGOs have become more market oriented, both in terms of their business models and in terms of their approach. On the other hand, private actors have also become more socially engaged, and advances in technology and communications have brought new opportunities for market sector actors to create social impacts. The result has been an increasing trend of social enterprises (SEs), hybrid organisations created for a social purpose but participating actively in the market for their subsistence. This paper examines the differences between traditional NGOs, funded mainly by government grants and donations, and these new actors that rely primarily on market-based income. Furthermore, this study tries to examine how Dutch NGOs and SEs are creating links between activities focused on market building and actual participation in markets, a challenge that Helmsing and Knorringa identified in 2008. To do this, 21 SEs were interviewed and another 16 NGOs were studied on the basis of interviews (5) and their annual reports, strategy papers and official websites. We find that there are three ways in which NGOs and SEs are successfully “bridging the gap” between market building and market participation: i) through official partnerships, ii) individually by tapping market and non-market sources of funding, using new technologies and leveraging from new forms of private philanthropy, and iii) by selling specialized “market building” services that guarantee an active participation of the private sector. Furthermore, the ability of SEs to engage in market building activities and of NGOs to participate in the market depends largely on their origins and the business models and financial strategies that they adopt.
