Community integration in social housing: The colombian case = Integración comunitaria en vivienda de interés social: el caso colombiano

Por: Alina Cárdenas Rey | Fecha: 2015

In the Colombian context, which ideally will now start a post-conflict period, it is necessary for the government to pursue strategies to prevent the causes of the conflict. This study considers the hypothesis that one possible cause for future conflict is the problems that emanate from coexistence of social housing neighbours. In Colombia, social housing programmes focus on providing shelter, in the sense that it is understood as something only physical. The problem is that this notion ignores the need of people to generate community integration. This study takes a conceptual approach to the issue by addressing the debates around citizenship as an identity and active citizenship. It also analyses concepts such as social capital, state-society-synergy and finally community and social housing. The study focuses on the case of Colombia, analysing the context and the challenges of social housing. It evaluates the housing policy and community integration programs of different institutions of the national government. Finally, it concludes with the suggestion that the government should have a participatory approach to building social housing that will help with arraigo (attachment) and to form the social fabric to achieve community integration, accomplishing better conviviality and housing conditions.

Metodologia de análise e avaliação exergoambiental de plantas termoelétricas operando em combustão combinada carvão – Biomassa

Por: Alvaro Hernán Restrepo Victoria | Fecha: 2012

A technological and environmental alternative has been studied for about a decade to reduce the consumption of coal. It consists of substitute one part of the coal by biomass (neutral generated of CO2) in a co-_ring process. The co-_ring process consists of the controlled combustion of two or more fuels in the same burner. According to research performed in the US and Europe this process has economic and technical viability. And depending on the characteristics of the fuel, this process can contribute reducing the greenhouse gases (GHG). This thesis presents a methodological proposal to analyze and evaluate a thermoelectric power plant from the exergoenviromental point of view, operating in co-_ring process and using coal and biomass. The boundary of the problem is composed by the power plant and the technological paths to obtain and manipulate the fuels. Exergy is used in the thermodynamic analysis and the life cycle assessment method is proposed to quantify the environmental impact. The climate change category was used following the global warming potential index. Two scenarios were evaluated: scenario A corresponds to the power plant operating with 100% coal and scenario B corresponds to the power plant operating in co-_ring with 90% of coal and 10% of biomass. The technological route used for the coal is established between the southern mineral region of the state of Santa Catarina and the Jorge Lacerda thermoelectric power plant complex, which is located at Capivari de Baixo. The information utilized for the biomass path was obtained from the research performed in the thermoelectric power plant complex. The purpose of this task was to use the biomass from the rice farms as fuel. The analysis showed that the power plant is largely responsible for exergy destruction. Moreover it has the largest generated impact associated with the analyzed category. From these results, an exergoenvironmental analysis for the representative thermodynamic cycle was performed. The results showed that the boiler constitutes the equipment with the largest potential of improvement.  Finally, an exergoenvironmental global index was proposed to compare the exergoenvironmental impact of the thermoelectric generation process for both scenarios, which were compared with Carnot cycle scenario. The exergoenvironmental global index showed that 11% improvement is possible for the scenario B when compared with scenario A without taking in account the biomass microbial decomposition and up to the 35% when the decomposition was considered.

Non Timber Forest Products In Colombia: Review Of Constraints For Effective Commercialisation = Productos Forestales no Maderables en Colombia: Revisión de los Cuellos de Botella para su Efectiva Comercialización

Por: Rodrigo Martínez | Fecha: 2004

A review of the main issues that affect the livelihoods of non timber forest products (NTFP) focusing on the commercialisation issues of gatherers/producers and traders, was made for Colombia. It aimed to investigate broadly which are some of the cultural, economic, social, environmental, marketing and legislative issues that affect the outcomes for NTFP livelihoods. The sustainable rural livelihood framework was used to understand the main issues affecting NTFP livelihoods and to propose alternatives to improve the constraints found in NTFP development and commercialisation. The study identify the great importance of NTFP local and regional markets for rural development, and some data was given for international markets in order to understand the magnitude of the commerce and the possibilities that might arise for some promissory products. The review of some institutional and organisation incentives influencing NTFP production and commercialisation was undertaken by reviewing the forestry policies and some of its instruments. The study used secondary data of reports made mainly in Latin-America. The report concludes that the policies and norms that influence NTFP, such as the forestry policy and plans do not consider the importance of NTFP for social and environmental objectives. For NTFP research, the analysis of the commercialisation process is strongly co-related to social networks, ecology, cultural taboos, norms for management of NTFP and effectiveness of support organisations. NTFP livelihoods can be seriously affected by government organisations and NGO’s if they are treated as traditional commodities because of the fragility and uniqueness of their ecology, economy and social structures. The report gives some recommendations to government agencies and researchers that wish to mend the constraints found for NTFP successful development.

The challenges of legal transplants in a globalized context: A case study on ‘working’ examples = Los desafíos de los trasplantes legales en un contexto globalizado: Estudio de casos positivos

Por: María Paula Reyes Gaitán | Fecha: 2014

Globalization has led legal systems to influence each other throughout history and legal transplants have not been immune to that process either. Nowadays we do not just see examples of legal transplants but come across cases of 'cross-fertilization' of case law. An emergence of unstudied trends that have spread around the world in a voluntary and involuntary way across legal cultures can also be witnessed. However it seems that legal transplants have been largely misunderstood and have been condemned as mere copy-paste exercises due to their history. This paper studies the different theories of legal transplants in comparative law and also analyses some particular cases that have eventually ‘worked’ efficiently both in the country of origin and in the country where those laws were adopted. We can no longer say that legal transplants are impossible; they are a reality we cannot run away from. Amongst the many challenges faced by this phenomenon, the primary one is to overcome all the obstacles imposed by a ‘legal globalization’ that is threatening developing countries by focusing more on the liberalization of markets, rather than on policies supporting social welfare. Despite this fact, there is still hope for a new concept of ‘legal globalization’, one that includes executing a serious study of the trends that not only developing countries are in need of, but also is a need of the developed countries, which is the adoption of policies towards social welfare, one of the biggest challenges that face modern legal comparatists today.

Corazón y ciencia

Por: Wilkie Collins | Fecha: 2011

La historia de amor entre dos jóvenes es el telón de fondo que el genio de Wilkie Collins utiliza en Corazón y ciencia para dar voz a su ataque contra la vivisección. El joven doctor Ovid Vere, el día antes de marcharse al extranjero, donde tiene que ir para recuperar su afectada salud, se topa casualmente, en una calle de Londres, con una atractiva mujer de la que se enamora a primera vista y que lo conduce a un concierto donde ella se desmaya. Después de ayudarla, en calidad de médico, descubre que se trata de Carmina Graywell, la prima hermana que, después de quedarse huérfana, había viajado de Italia a Inglaterra para ser educada por la madre del mismo Ovid (que persigue la herencia de su sobrina...).

Cuatro encuentros

Por: Henry James | Fecha: 2007

Publicada en 1877, esta irónica nouvelle es un modelo del género. El mismo Henry James así lo indicaba en sus cuadernos: "La concisión de Cuatro encuentros (. . . ) ¡eso es hacia lo que debo tender! ". La historia de la señorita Spencer, cuyo sueño es viajar a Europa y lo consigue, y cómo se resuelve su regreso a Estados Unidos constituye una metáfora de muchas de las aspiraciones humanas. El retrato de la protagonista está subordinado a la perturbadora seducción que ejercen sobre el lector el carácter ilusorio de su obsesión y el posterior misterio de la renuncia

Diario de un hombre de cincuenta de años

Por: Henry James | Fecha: 2004

Bajo la forma de un diario personal, un quincuagenario de viaje por Florencia anota los episodios de un acontecimiento extraordinario para él: acaba de conocer a la hija de la que fue su amor de juventud casi treinta años antes, y a su pretendiente, un joven inglés, e intuye en esta relación la exacta repetición de su propia historia sentimental. Historia que él había resuelto con una dolorosa ruptura, y en la analogía que ahora establece se empeña en proteger a su alter ego del peligro que lo acecha
