Educación y desarrollo: para Colombia, ¿una relación con posibilidades de realización sociohistórica?

This document is part of a humanistic approach to education and development to locate the human being as the center of political and socio-economic processes in a historical moment that has been defined as "the knowledge society". Two hypotheses are set: a) The current economic model of globalization generates greater competitive disadvantage immanent countries "developing" or as in the last fifteen years have been called "emerging economies", with respect to developed countries and as a consequence the inequality gap widens, and b)Economic development is critical for the guidance of the educational policies and the production of knowledge, which in the current conditions, it also reinforces the conditions of existence competitive disadvantages. Then puts into question the concept of development implicit in the economic model and is making initial approaches to reflection and research regarding the relations between education and development.El presente documento se enmarca dentro de una concepción humanista de la educación y el desarrollo al ubicar al ser humano como el centro de los procesos políticos y económico-sociales, en un momento histórico que se ha definido como “la sociedad del conocimiento”. Dos hipótesis se exponen: a) el actual modelo económico de la globalización genera de forma inmanente mayores desventajas competitivas de los países en “vía de desarrollo” o, como en los últimos quince años se les ha llamado, “de economías emergentes”, con respecto a los países desarrollados y, como consecuencia de esto, se amplía la brecha de inequidad. b) El desarrollo económico es determinante en las orientaciones de las políticas públicas educativas y de producción de conocimiento, lo que, en las condiciones actuales, también refuerza las condiciones de existencia de las desventajas competitivas. Seguidamente se pone en tela de juicio el concepto de desarrollo implícito en el modelo económico y se trata de hacer planteamientos iniciales para la reflexión y la investigación con respecto a las relaciones establecidas entre la educación y el desarrollo

Electrical Lab-on-a-Chip for Ex Vivo Study on the Influence of Electric Fields on Pollen Cells

Pollen tubes are polarly growing plant cells that are able to respond to a combination of chemical, mechanical, and electrical cues during their journey through the flower pistil in order to accomplish fertilization. How signals are perceived and processed in the pollen tube is still poorly understood and evidence for electrical guidance, in particular, is vague and highly contradictory. To generate reproducible experimental conditions for ex vivo pollen cell cultures, here we present a low-cost, reusable Electrical Lab-on-a-Chip (ELoC) for investigating the influence of electric fields on growing cells. Viability of pollen growth using a structured microfluidic network is first investigated and validated. Then the integration of microelectrodes into the device is addressed in detail. Characterization of the pollen growth medium conductivity and simulation of the ELoC electrical configuration were carried out to define the experimental conditions. Reusability of the microdevice is achieved by structuring the design into two separate rebondable modules: a microfluidic module and a microelectrode module. Two experimental approaches were realized: a batch design for exposing simultaneously a large number of cells to a global electric field, and a single-cell design in which a localized electric field is applied to individual cells. Extensive batch results indicate that DC fields were inhibitory above 6 V/cm. However, switching to AC fields re-established pollen tube growth at frequencies above 100 mHz, suggesting a significant role of the medium conductivity in controlling the cellular response. Unlike macroscopic open-assay experimental setups, single-cell tests further indicate no reorientation of pollen tube growth, suggesting that previously reported tropic behavior was caused by ion movement in the substrate rather than by a direct effect of the electric field on the cell

Apuntes para una comprensión moral sobre los marcos de legalidad de la justicia y las víctimas en Colombia

This article points out that Truth is the only road to reconciliation from the viewpoint of Christian moral and with it biblical hermeneutics is extremely useful. The main focus is on past special events occurred in Colombia and the enactment of many lawsintended to go in the direction in search for peace.En este artículo se tratará el tema de la verdad como camino para llegar a la reconciliación desde la perspectiva de la moral cristiana y con ella la hermenéutica bíblica es de gran utilidad. Se fi jará la atención sobre algunos acontecimientos que han tenido lugar en Colombia con la promulgación de algunas leyes que pretenden avanzar hacia ese camino de la paz

Editorial

Los textos que se incluyen en esta edición son una buena muestra del itinerario que sigue la revista y de las iniciativas que promueve la Facultad de Humanidades y Ciencias Sociales de la Pontificia Universidad Javeriana Cali. En la sección de artículos, Carmiña Navia Velasco, en su texto “Ciudades hoy, diálogos con la tradición bíblica”, busca tomarle el pulso a la ciudad desde la espiritualidad e interpretar los nuevos lenguajes que están surgiendo. Además, aborda algunas realidades complejas:esperanza/desesperanza de un pueblo, violencia, injusticias, pobreza, sinsentido de la existencia. Por eso, tal como afirma Navia: desde la tradición bíblica es posible pensar e incidir en ciertas dinámicas de las ciudades y, al respecto, nos deja la siguiente pregunta: ¿cómo dialoga nuestro ser cristiano con esta realidad múltiple y compleja? En últimas, se busca que la Biblia ilumine la  vida de las personas y de las comunidades en la ciudad

DARING TO THINK IS BEGINNING TO FIGHT: THE HISTORY OF MAGAZINE ALTERNATIVA—COLOMBIA, 1974-1980

This case study of alternative, radical journalism in Latin America during the 1970s, seeks to clarify and define the characteristics and limits of this model in concrete, specific historical circumstances. It traces the history of Alternativa, a leftist magazine published between February 1974 and 1980 in Bogotá, Colombia when three groups of people from different backgrounds devised a journalistic alternative model based on four objectives (counter-informing; investigation, analysis and interpretation; divulging the people's struggles; and propitiating the unity of the left), to effect a lasting change in Colombia's society. The founders' common Marxist background determined the magazine's content and its approach. Initially, they declared themselves independent and neutral toward the left's groups and decided to reach a wide audience through mass circulation. The narrative shows how inner tensions resulting from principled differences among the magazine's creators and from political circumstances led to two crises that tested its founding principles and determined its journalistic evolution. It also shows the struggle of the magazine to survive in a hostile climate, against a notoriously reckless and corrupt regime, testing the limits of the freedom of the press. In the first phase, the narrative reviews the history of the country as seen through the eyes of the publication, which contested the official version in the mainstream news media. In the second phase, the investigation highlights paramount issues such as human rights violations, corruption and the role of the press, through the magazine's critical coverage of Colombia's armed forces and police. In the third phase, the dissertation explores the magazine's complex relationship with the left, which eventually led to its demise. As author of this dissertation, I was witness to the events covered by Alternativa, and was part of the staff of writers in the magazine's third and last stage, with an inside view of a journalistic phenomenon crucial to understanding Colombia's present troubles

La solidaridad: nuevas utopías en la moral social y en la economía. A propósito de la encíclica Caritas in Veritate

The crisis in the economic and financial system poses new logics of understanding, seeking to recover alternative ways of development, thus, enabling that the dreams of another different world are still possible. It is not, therefore, to rescue a model that has become decadent and scandal, leading to the accumulation of capital in few hands, while vast majorities increase their misery. It is necessary to outline the necessary elements for understanding the current “social system” that makes difficult the future options that manipulates reality from the individualism and isolation. It should, therefore, explain a proposal to generate meaningful and significative alternatives of social life and the responsibilities of the human economy. Issues that are attracted by the Magisterium of the Church in Caritas in veritate. Perhaps, has our life a different meaning and a moral obligation from building a more just world for all?La situación de crisis del sistema económico-financiero plantea nuevas lógicas de comprensión, tendientes a recuperar formas alternativas de desarrollo, para así permitir que los sueños de un mundo diferente sigan siendo posibles. No se trata, por tanto, de rescatar un modelo que se ha tornado decadente y escandaloso, generando la acumulación de capital en pocas manos, mientras inmensas mayorías aumentan su miseria. Se requiere esbozar los elementos necesarios para la comprensión del “sistema social” actual, que dificultan las opciones de futuro, que instrumentaliza la realidad, desde el individualismo y la incomunicación. Es preciso, por consiguiente, explicitar una propuesta desde la cual se generen alternativas de sentido y significación sobre la vida social y las responsabilidades que conlleva la economía humana, temas sobre los que llama la atención el magisterio de la iglesia en Caritas in Veritate. ¿Acaso, nuestra vida tiene otro sentido y otra obligación moral que aquella de construir un mundo mas justo para todos

The VLT-FLAMES Tarantula Survey XXI. Stellar spin rates of O-type spectroscopic binaries

The initial distribution of spin rates of massive stars is a fingerprint of their elusive formation process. It also sets a key initial condition for stellar evolution and is thus an important ingredient in stellar population synthesis. So far, most studies have focused on single stars. Most O stars are however found in multiple systems. By establishing the spin-rate distribution of a sizeable sample of O-type spectroscopic binaries and by comparing the distributions of binary sub-populations with one another as well as with that of presumed single stars in the same region, we aim to constrain the initial spin distribution of O stars in binaries, and to identify signatures of the physical mechanisms that affect the evolution of the massive stars spin rates. We use ground-based optical spectroscopy obtained in the framework of the VLT-FLAMES Tarantula Survey (VFTS) to establish the projected equatorial rotational velocities (\vrot) for components of 114 spectroscopic binaries in 30 Doradus. The \vrot\ values are derived from the full-width at half-maximum (FWHM) of a set of spectral lines, using a FWHM vs. \vrot\ calibration that we derive based on previous line analysis methods applied to single O-type stars in the VFTS sample. The overall \vrot\ distribution of the primary stars resembles that of single O-type stars in the VFTS, featuring a low-velocity peak (at \vrot < 200 kms) and a shoulder at intermediate velocities (200 < \vrot < 300 kms). The distributions of binaries and single stars however differ in two ways. First, the main peak at \vrot \sim100 kms is broader and slightly shifted toward higher spin rates in the binary distribution compared to that of the presumed-single stars. Second, the \vrot distribution of primaries lacks a significant population of stars spinning faster than 300 kms while such a population is clearly present in the single star sample.Comment: 16 pages, 16 figures, paper accepted in Astronomy & Astrophysic
