Black Politics of Folklore: Expanding the Sites and Forms of Politics in Colombia

This paper puts into question ideas of politics limited to the theories of social movements and contentious politics. In using the concept of black counterpublic, understood as a web of relations and spaces, I show how black politics of folklore expands the sites and forms of politics in Colombia of 1960. In doing so, I describe two aspects of the black counterpublic from the point of view of black political intellectuals into the racialized field of Colombian folklore: a. the way black political intellectuals understood race and racism in Colombia and, b. their forms of politics. That is, their form of organization and mobilization. For this, I propose a new understanding of folklore beyond ideas of entertainments, apolitical culturalism and essentialism which, in turn, make black politics look trivialized and less political under the integrationist racial project of the mestizo State. Also, I shed some light on the idea of race and racism from below, from the point of view of black political intellectuals; and I pluralize and decentralize black politics from social movement understanding of politics

El mensaje de Jesús y el mensaje de Pablo desde una lectura no teológica del Nuevo Testamento

La pregunta que trata de responder este articulo es si el Nuevo Testamento aceptado por todos los cristianos como libro sagrado y base de su fe, posee realmente una unidad doctrinal. Para ello, el análisis parte de dos pilares fundamentales de la fe cristiana: los evangelios de Marcos y Mateo, por un lado, y las cartas de Pablo, por otro. Ahora bien, la comparación se llevara a cabo teniendo como base tres aspectos, a saber: el mensaje de salvación que anuncian, las condiciones necesarias para acceder a la salvación y los destinatarios del mensaje. El análisis de los textos se hará desde una perspectiva filosófica, no teológica, que busca cotejar los textos a partir de lo que ellos mismos dicen, prescindiendo de presupuestos de fe, para determinar si existe unidad doctrinal entre ambas visiones del Nuevo Testamento. De ahí que su propósito no es mostrar si los textos son o no falsos, si coinciden o no con lo que el Jesus histórico realmente quiso decir, sino verificar si la unidad doctrinal del cristianismo que cada cristiano asume de hecho en su práctica (así otros cristianos discrepen de ella) realmente es un hecho constatable en su propio texto sagrado

¿Es posible la cultura sin religión?: Un estudio desde la crítica a la religión de Sigmund Freud.

El objetivo principal de la investigación es responder a la pregunta por la posibilidad de la cultura sin religión, esto es, si es posible que la cultura prescinda, para su funcionamiento de categorías religiosas. Para ello se toma como punto de partida la crítica a la religión de Sigmund Freud: se delimitan los conceptos necesarios, como ello, superyó, yo, neurosis, cultura y religión. Se constituye, a partir de esos elementos, una definición sintética de cultura y de religión, que son la base para responder a la pregunta. Finalmente, se concluye que la cultura sin religión es posible si se asume lo que Freud denomina una educación para la realidad

Anticipatory life cycle analysis framework for sustainable management of end-of-life crystalline silicon photovoltaic panels

In this research, a framework for performing Anticipatory Life Cycle Analysis (a-LCA) has been developed to identify the sustainable end of life (EoL) management option for crystalline silicon photovoltaic (PV) panels. a-LCA can be used to stimulate proactive and sustainable decision making for emerging technologies through stakeholder participation. In this research, stakeholders related to EoL management of PV panels participated through a survey to identify and prioritize economic, environmental, and social indicators for PV EoL management. Several EoL strategies like bulk material recycling (centralized and decentralized), high value material recycling, and landfilling were chosen and assessed for the prioritised sustainability indicators. The EoL strategies were then ranked through a multi-criteria decision analysis tool for their level of sustainability. High value material recycling (close to 100% material recovery) was identified as the most sustainable option followed by bulk recycling of PV panels that recover only the major constituents, such as aluminium, glass, and e-waste. Landfilling remained the least preferred option, although it currently has an economic advantage over other recycling options, highlighting the need to shift the user preferences. The developed a-LCA framework is iterative and can be applied by decision makers for different EoL management strategies in the future.This research was supported by the by R2MIT project (ref.

Towards a sustainability-based society: an analysis of fundamental values from the perspective of economics and philosophy

Sustainable development faces numerous challenges when applied in the real-world global economic model of capitalism. The prevailing trend of the economic pillar, in the implementation of sustainability planning based on the triple bottom line (TBL), compromises both the environment and society. This paper aims to address such challenges by proposing a new vision of strong sustainability that is characterised by: i) considering the global economic model in a real-world approach; and ii) having strong core values of sustainability. To evaluate the first characteristic, a review of the literature regarding capitalism and TBL-sustainability has been conducted. For the second characteristic, a historical-philosophical discussion around the role of society and the economy has been conducted. The results suggest that an actual sustainable society requires a fixed and sustained focus on environmental and social pillars together with a flexible organisation of society (including its economic model).Peer ReviewedObjectius de Desenvolupament Sostenible::2 - Fam zeroObjectius de Desenvolupament Sostenible::3 - Salut i BenestarObjectius de Desenvolupament Sostenible::1 - Fi de la PobresaObjectius de Desenvolupament Sostenible::4 - Educació de QualitatObjectius de Desenvolupament Sostenible::15 - Vida d'Ecosistemes TerrestresObjectius de Desenvolupament Sostenible::17 - Aliança per a Aconseguir els ObjetiusObjectius de Desenvolupament Sostenible::16 - Pau, Justícia i Institucions SòlidesObjectius de Desenvolupament Sostenible::5 - Igualtat de GènereObjectius de Desenvolupament Sostenible::6 - Aigua Neta i SanejamentObjectius de Desenvolupament Sostenible::7 - Energia Assequible i No ContaminantObjectius de Desenvolupament Sostenible::9 - Indústria, Innovació i InfraestructuraObjectius de Desenvolupament Sostenible::10 - Reducció de les DesigualtatsObjectius de Desenvolupament Sostenible::11 - Ciutats i Comunitats SosteniblesObjectius de Desenvolupament Sostenible::12 - Producció i Consum ResponsablesObjectius de Desenvolupament Sostenible::13 - Acció per al ClimaObjectius de Desenvolupament Sostenible::14 - Vida SubmarinaPostprint (published version

Consecuencias del lavado de activos en Colombia, durante el periodo 1999-2010

La seguridad mundial está bajo la inminente amenaza de las organizaciones criminales y el lavado de activos. Lo que ha hecho evidente la dimensión del conflicto abarca talentes complejos, que en muchos casos como es el de Colombia afectan la economía y la seguridad de los países. Desde un punto de vista económico, el lavado de capitales se ha convertido en una molestia que afecta seriamente los mercados financieros del mundo, pues le ha permitido a las organizaciones delictivas penetrar en los negocios lícitos escondiendo sus ganancias, lo que conduce a distorsionar la actividad financiera, comercial y empresarial legítima, generando corrupción a su paso

Selectrodialysis and bipolar membrane electrodialysis combination for industrial process brines treatment: Monovalent-divalent ions separation and acid and base production

Chemical industries generate large amounts of wastewater rich in different chemical constituents. Amongst these, salts at high concentrations are of major concern, making necessary the treatment of saline effluents before discharge. Because most of these rejected streams comprise a combination of more than one salt at high concentration, it is reasonable to try to separate and revalorize them to promote circular economy at industry site level. For this reason, ion-exchange membranes based technologies were integrated in this study: selectrodialysis (SED) and electrodialysis with bipolar membranes (EDBM). Different process brines composed by Na2SO4 and NaCl at different concentrations were treated first by SED to separate each salt, and then by EDBM to produce base (NaOH) and acids (HCl and H2SO4) from each salt. The optimum of both electrolyte nature and concentration of the SED stack streams was evaluated. Results indicated that it was possible to separate Cl- and SO42- depending on the anionic membrane, initial electrolytes and concentrations of each stream. Pure NaOH and a mixture of HCl and H2SO4 with different purities could be obtained. Energy consumption evolutions were plotted and an optimal zone work was found where the consumption values were acceptable.Peer ReviewedPostprint (author's final draft

Integration of monopolar and bipolar electrodialysis for valorization of seawater reverse osmosis desalination brines: Production of strong acid and base

Water scarcity in the Mediterranean basin has been solved by using seawater desalination reverse osmosis technology (SWD-RO). This technology produces brine which is discharged back into the sea resulting in an environmental impact on marine ecosystems. Under the circular economy approach, the aim of this work is to recover resources from NaCl-rich brine (~60-70 g/L), e.g. in the form of NaOH and HCl, by integration of two ion exchange-based membrane technologies and quantify the electrical energy consumption. Electrodialysis (ED) incorporating monovalent selective cation exchange membranes as divalent ions purification and concentration of the NaCl present in the SWD-RO brine, was integrated with bipolar membrane ED (EDBM) to produce NaOH and HCl. Current densities of 0.30–0.40 kA/m2 at two temperature ranges simulating different seawater temperature regimes (15-18 ºC and 22-28ºC) were tested and a pure NaCl solution was used as starting concentrate stream. NaCl-rich brines with 100 or 200 gNaCl/L were obtained by ED and then introduced in the EDBM stack producing HCl and NaOH up to 2 M, depending on the initial concentrations. A minimum energy consumption of 1.7 kWh/kgNaOH was calculated when working by EDBM with initial concentrations of 104 g NaCl/L and 0.24 M HCl and NaOH.Peer ReviewedPostprint (author's final draft

El dosel sagrado. Para una teoría sociológica de la religión

A pesar de que existe la tradición de reseñar libros publicados o reeditados recientemente, después de releer El dosel sagrado, evidencio su actualidad y no resisto la tentación de reseñarlo con la esperanza de que un editor generoso decida publicar esta evocación. En efecto, El dosel sagrado no sólo es un libro necesario para quien pretende abordar el estudio del fenómeno religioso hoy, sino que es imprescindible para quien quiera comprender la relación entre la sociedad y la religión. Más aún, en un momento en el que las creencias se transforman, las religiones se des-institucionalizan y, al parecer, se están dando ciertos procesos secularizadores en escenarios donde los estudiosos del campo religioso insisten en ver manifestaciones de índole sagrado
