Bosa entre la formalidad y la informalidad: una apuesta por la construcción social de un territorio sustentable

Bosa, ubicada en el suroccidente de Bogotá, tiene alrededor de 700.000 habitantes, es uno de los territorios de mayor desarrollo urbano reciente en Colombia; en la primera década del siglo XXI incrementó su población un 50%, producto de procesos contradictorios entre la formalidad y la informalidad; es el único sector conurbado en Bogotá. El presente artículo refiere la historia del proceso urbanístico de este territorio a partir de los setenta, más que la morfología urbana, la atención se centra en el diseño y la gestión urbana especialmente en el papel de los agentes urbanos para transformar condiciones adversas, producto del desarrollo informal a través de la autogestión y la participación ciudadana acompañada de entidades gubernamentales que han priorizado el desarrollo de proyectos de vivienda de la ciudad en la localidad, atrayendo a promotores inmobiliarios privados generando incremento del precio del suelo y una de las mayores tasas de densificación.Bosa, located in the southwest of Bogota, has around 700,000 inhabitants, is one of the areas most recent urban development in Colombia, in the first decade of the century the population increased by 50% due to contradictory processes between formality and informality; is the only sector in Bogotá with conurbation. This article relates the history of urban planning process of this territory from the seventies, but the urban morphology, the focus is on design and urban management especially in the role of urban actors to transform adverse conditions, product informal development through self-management and citizen participation accompanied by government entities that have prioritized the development of housing projects of the city in the town, attracting private developers to generate increase in land prices and one of the highest rates of densification.Peer Reviewe

Transforming food systems under a changing climate in Latin America: A climate policy review

Agriculture is highly vulnerable to climate change, but at the same time, it is the main contributor to climate change Governments have recognized that facing climate change is essential to address a sustainable development pathway, but so far little progress has been achieved Thus there is a need for rapid and transformative actions that tackle climate change impacts while achieving sustainable rural development Nevertheless, the way current policies are addressing actions towards transformative actions is unclear concerning sustainable pathways of food systems in the face of climate change. In this sense, this paper reviews current climate change-related policies of Latin American countries to identify whether they address transformational actions in the agricultural sector or food systems in relation to climate change Research questions include which countries state in their policies transformative actions? Are Latin American national policies in line with their international commitments? In order to answer these questions we used different methods of text analysis applied to the policy framework of Latin American countries to assess the integration level of eight components that Campbell et al 2018 propose in the theory of change to drive the transformation of food systems under climate chang

Organizaciones populares de vivienda: alternativa al déficit de vivienda adecuada en Colombia: estudio comparativo de caso OPV ASOVIVIR con MISN Ciudad Verde

Este trabajo busca indagar sobre las opciones de las Organizaciones Populares de Vivienda para brindar alternativas de acceso a la vivienda adecuada en Colombia (en concordancia con el Pacto de Derechos Sociales Económicos y Culturales), a partir de la comparación entre “Ciudad Verde” en Soacha, el mayor Macroproyecto de Interés Social Nacional (con una producción cercana a 50 mil unidades) y la Asociación de Vivienda Integral ASOVIVIR, que a principios de los 90 construyó 550 viviendas unifamiliares a través de un proceso autogestionario y a partir de la cual se dio origen a la Federación de Vivienda Popular FENAVIP que desarrolló más de 20.000 viviendas en el país, con ciertas ventajas diferenciales frente a la producción de los agentes inmobiliarios con ánimo de lucro, con quienes el Gobierno Nacional desarrolla los Macroproyectos, facilitando la adecuación masiva de suelo para vivienda social pero sin generar unidades habitacionales completamente adecuadas a las necesidades de sus habitantes.This paper seeks to investigate the options of Popular Housing Organizations to provide alternatives for access to adequate housing in Colombia (according to the Economic and Cultural Social Rights pact), based on the comparison between "Green City" in Soacha , The largest Macroproject of National Social Interest (with a production of about 50 thousand units) and the Association of Comprehensive Housing ASOVIVIR, which in the early 1990s built 550 single-family homes through a self-management process and gave rise to the Housing Federation Popular FENAVIP that developed more than 20,000 houses in the country, with certain differential advantages compared to the production of real estate agents for profit, with whom the National Government develops the Macroprojects, facilitating the massive adaptation of land for social housing but without generating housing units completely adequate to the needs of its inhabitants

Bose-Einstein Condensates in Charged Black-Hole Spacetimes

We analyze Bose-Einstein condensates on three types of spherically symmetric and static charged black-hole spacetimes: The Reissner-Nordstr\"om spacetime, Hoffmann's Born-Infeld black-hole spacetime, and the regular Ay\'on-Beato-Garc\'ia spacetime. The Bose-Einstein condensate is modeled in terms of a massive scalar field that satisfies a Klein-Gordon equation with a self-interaction term. The scalar field is assumed to be uncharged and not self-gravitating. If the mass parameter of the scalar field is chosen sufficiently small, there are quasi-bound states of the scalar field that may be interpreted as dark matter clouds. We estimate the size and the total energy of such clouds around charged supermassive black holes and we investigate if their observable features can be used for discriminating between the different types of charged black holes.Comment: 19 pages, 8 figure

¿Hacia una delimitación de "grupos estratégicos" entre los equipos de investigación en finanzas españoles?

En este trabajo se pretende trasladar el planteamiento relativo al análisis de grupos estratégicos, nacido en el seno del análisis estratégico y de la economía industrial, a un ámbito diferente, pero que presenta ciertas similitudes con el originario: el de los equipos de investigación en el área de la Economía Financiera. La finalidad es, por tanto, identificar grupos estratégicos entre dichos equipos. Para ello, se han utilizado, por una parte, análisis de correspondencias sobre las frecuencias de los trabajos elaborados por los equipos, tanto por subáreas como por carácter, y por otra^ análisis cluster en base a estos dos aspectos

Inserción de Colombia en la Cuenca del Pacifico: el nuevo eje de la economía mundial

El comercio internacional ha presentado, a lo largo de los años, un fuerte dinamismo que ha impulsado a las naciones del mundo ha desarrollar distintas estrategias para afrontar las nuevos cambios y desafíos que ha traído consigo la globalización. El centro económico mundial se ha trasladado, en el pasado, del Mediterráneo al Atlántico, y hoy parece seguir una nueva tendencia hacia el Pacífico. El enorme potencial de su mercado y los grandes avances para la cooperación comercial que se han logrado entre los países que conforman la Cuenca del Pacífico, confirma la importancia de esta región, que se ha convertido en el nuevo epicentro económico mundial. Colombia cuenta con una posición geográfica privilegiada que le permite tener un fácil acceso al comercio con los países de la Cuenca. Sin embargo, su inserción a este mercado ha sido débil y tardío, si se compara con otros países de América Latina como Chile, que cuenta con una participación activa en este bloque económico desde hace varias décadas. Es necesario, de esta manera, que el país implemente estrategias enfocadas a lograr un cambio en el enfoque en su política exterior, que le permita fortalecer las relaciones comerciales con la otras naciones que hacen parte de la Cuenca del pacífico, para aprovechar eficazmente las oportunidades y ventajas que se presentan en este mercado y que pueden ser determinantes para el desarrollo económico del país en el futuroThe international commerce has presented, over the years, a strong dynamism that has driven all nations over the world to develop different strategies to face the new changes and challenges that have come along with the process of globalization. The world´s economic center has moved for the Mediterranean to the Atlantic, in the past, and it seems that it follows a new trend towards the Pacific. The great potential of its market and the significant progress of the commercial cooperation between the countries within the Pacific basin, confirms the importance of this region that has become the new global economic center. Colombia has a privileged geographical position that provides the country with an important access to the commerce within the basin. However, its inclusion in this market has been weak and delayed, compared with other Latin American countries such as Chile, which has an active participation in this economic bloc through the past few decades. It has become necessary, that the country sets up new strategies aimed to achieve a change in its foreign policy. Theses will strengthen the commercial relations with other nations from the Pacific Basin, to take advantage of the opportunities that are present in this market and that can be crucial for the future economic development of the country

Realización de debates para evaluar la competencia transversal de comunicación oral: de la teoría a la práctica

La evaluación de la competencia transversal de comunicación oral suele resultar problemática, sobre todo en asignaturas técnicas. A la de por sí, generalmente, baja motivación del profesorado para evaluar este tipo de competencias se añade la dificultad de diseñar un proceso de evaluación que realmente contemple todos los aspectos involucrados: capacidad de síntesis y de argumentación, comunicación oral apropiada y amena, lenguaje gestual, dominio de la materia y del escenario y control del tiempo de exposición. Con frecuencia, el profesorado se limita a incluir una exposición oral como parte de la realización de una actividad que evalúa competencias técnicas. Por tanto, solo se efectúa una evaluación superficial de algunos de los aspectos mencionados. El foco se sitúa en el contenido técnico de la actividad y la exposición oral se considera como algo marginal, ya que los estudiantes suelen realizar un esfuerzo considerable en la preparación de contenidos y no hallan motivación en hacerla bien. Este problema se hace aún más patente cuando hay un número elevado de alumnos a evaluar, lo que ocurre habitualmente en asignaturas de primer curso. En este artículo, mostraremos una aplicación práctica de la realización de debates para la evaluación de la capacidad de comunicación oral, conjuntamente con la evaluación de determinadas competencias técnicas.SUMMARY -- To devise means to make fair and accurate assessment of oral communication skills is a complex task. This becomes even more obvious in engineering subjects, since lecturers are frequently not motivated to spend much time on this task and, also, it’s difficult to set down suitable procedures which enable a reliable evaluation of every aspect involved: synthesis ability, argument development, appropriate pleasant oral communication, body language, stage presence, subject mastery and presentation time control. Frequently, lecturers simply include an oral presentation as part of an assignment where students exercise some technical skills. Therefore, just a plain assessment of a few of the above mentioned aspects is carried out. This way, the stress is on the technical skills exercised, while the oral presentation is considered as something secondary, since students usually make considerable efforts to satisfactorily solve the assignment with hardly any interest in making an adequate oral presentation. These inconveniences become even more evident when the number of students in the class is high, which typically happens among first course subjects. In this paper, we show a practical scheme for the assessment of oral communication skills based on conducting group debates while some technical skills are also assessed

Calibration of piezoelectric positioning actuators using a reference voltage-to-displacement transducer based on quartz tuning forks

We use a piezoelectric quartz tuning fork to calibrate the displacement of ceramic piezoelectric scanners which are widely employed in scanning probe microscopy. We measure the static piezoelectric response of a quartz tuning fork and find it to be highly linear, non-hysteretic and with negligible creep. These performance characteristics, close to those of an ideal transducer, make quartz transducers superior to ceramic piezoelectric actuators. Furthermore, quartz actuators in the form of a tuning fork have the advantage of yielding static displacements comparable to those of local probe microscope scanners. We use the static displacement of a quartz tuning fork as a reference to calibrate the three axis displacement of a ceramic piezoelectric scanner. Although this calibration technique is a non-traceable method, it can be more versatile than using calibration grids because it enables to characterize the linear and non-linear response of a piezoelectric scanner in a broad range of displacements, spanning from a fraction of a nanometer to hundreds of nanometers. In addition, the creep and the speed dependent piezoelectric response of ceramic scanners can be studied in detail.Comment: 9 pages, 3 figure
