EFECTO DEL GRADIENTE ALTITUDINAL SOBRE ASPECTOS AUTOECOLóGICOS DE ESPELETIA PYCNOPHYLLA ssp. ANGELENSIS CUATREC. (ASTERACEAE) EN EL PáRAMO EL INFIERNILLO (NARI?O-COLOMBIA)

Abstract: some autoecological features of espeletia pycnophylla ssp. angelensis cuatrec. such as its demographic structure, population density, spatial pattern of dispersion, production of reproductive structures, adult morphometry and survivorship, were studied in an altitudinal gradient on a dry paramo of nari?o (colombia). hypothesis proposed by other authors about a linear effect caused by the elevation on these variables were completely rejected. the elevation induces an ecoclinal effect on population density, and this density correlates negatively with both production of reproductive structures and adult sizes. these results elucidate an unequivocal effect of density-dependence phenomena on population fitness. the intermediate zone of the altitudinal gradient exhibits a high population density, but on the other hand show reduced corporal adult sizes, minimal production of reproductive structures and the probability of juveniles reaching advanced ages is low. evidently, this intermediate elevation can have favorable ecological conditions for the seedling establishment, wich increments population densities at long term. we propose that other author's generalizations about the influence of elevation on the autoecology of these plants are limited, because the particular life and disturbance stories of paramos and the spatial, ecological and genetic isolating are explicative factors impossible to take away from the context. the demographic structure of the population fitted the logarithmic model, revealing its early regeneration state from the last fire event on 2003 and the similarity of the survivorship curves among every elevation, probed a high demographic stability.

Abstract: Se estudió el efecto de la elevación sobre algunos aspectos autoecológicos de la especie Espeletia pycnophylla ssp. angelensis Cuatrec. (Asteraceae), tales como su estructura demográfica, densidad poblacional, patrón de distribución espacial, producción de estructuras reproductivas, morfometría de adultos y supervivencia, en un páramo seco del departamento de Nari o (Colombia). Las hipótesis propuestas por otros autores acerca del efecto lineal que la elevación produce sobre estas variables, fueron completamente rechazadas. La elevación induce un efecto coenoclínico sobre la densidad poblacional y ésta a su vez, se correlaciona negativamente con la producción de estructuras reproductivas y el tama o de los adultos, evidenciándose un efecto inequívoco del fenómeno de la densodependencia sobre el potencial biótico de la población. En la zona intermedia del gradiente, la densidad poblacional es máxima, pero los tama os corporales son reducidos, la producción de estructuras reproductivas es mínima y la probabilidad de que un juvenil alcance edades avanzadas es baja. Evidentemente, esta elevación intermedia estaría presentando condiciones ecológicas favorables para el establecimiento y supervivencia de plántulas, lo que a largo plazo conlleva a un aumento de la densidad poblacional. Se propone que las generalizaciones de otros autores acerca de la influencia de la elevación sobre la autoecología de estas plantas son inverosímiles y limitadas, ya que la historia particular de vida y disturbio del páramo y los aislamientos espaciales, ecológicos y genéticos, son factores explicativos que no pueden aislarse del contexto. Paralelamente, la población se ajustó al modelo demográfico logarítmico, revelando su temprano estado de regeneración frente a la última quema ocurrida en el 2003, y la similitud de las curvas de supervivencia entre todas las elevaciones, probó una alta estabilidad demográfica.

Abstract: the origins of the aps and the policy health for all go back to the eighteenth century and the movement of social medicine on 1848. twentieth century highlights the pioneering experiences of the years 30-50s. among them, chile, saskatchewan (canada), usa, south africa, with henry sigerist, sidney kark, salvador allende, gustavo molina, pioneering work of social medicine and epidemiology related to the anthropologist benjamin paul. as well as less recognized characters, especially the italian franco basaglia, aps who transformed psychiatric care and health with the principles of therapeutic freedom. to these are articulated numerous and unknown experiences in latin america and colombia with héctor abad gómez, santiago rengifo and césar uribe piedrahita by the process of phc renewal? of the ops. in latin america, the struggles for health were articulated to the struggles for a just society, with people like ernesto guevara in medicine, paulo freiré in pedagogy, theology and philosophy of liberation, and the sociologist camilo torres, who provided qualitative methodologies on health research, which altogether with views on integration such as human scale development, consider health services as key elements in people's lives, and contribute in building cross-disciplinary and intersectorial health for our today.
La medicina social y las experiencias de atención primaria de salud (APS) en Latinoamérica: historia con igual raíz

Polis : Revista de la Universidad Bolivariana , 2010,
Abstract: Los orígenes de la APS y de la Política de SALUD PARA TODOS se remontan al siglo XVIII y al movimiento de Medicina Social de 1848. Del siglo XX se destacan las experiencias pioneras de los a os 30-50s. Entre ellas, Chile, Saskachewa (Canadá), EUA, Suráfrica, con Henry Sigerist, Sidney Kark, Salvador Allende, Gustavo Molina, trabajos pioneros de la medicina y la epidemiologia social vinculados a los del antropólogo Benjamin Paul. Así como personajes menos reconocidos en APS especialmente el italiano Franco Basaglia transformador de la atención psiquiátrica y sanitaria con los principios de libertad terapéutica. A éstas están articuladas numerosas y desconocidas experiencias en América Latina y Colombia con Héctor Abad Gómez, Santiago Rengifo y César Uribe Piedrahita por el proceso de "Renovación de APS" de la OPS. En Latinoamérica, las luchas por la salud estaban articuladas a la luchas por una sociedad justa, con personajes como Ernesto Guevara desde la medicina, Paulo Freire en pedagogía, teología y filosofía de la liberación, y el sociólogo colombiano Camilo Torres, que aportaron metodologías cualitativas en la investigación en salud, los que junto aportes de integración como el Desarrollo a Escala Humana, consideran a los servicios sanitarios como elementos principales en la vida de las personas, y aportan a la construcción transdisciplinar e intersectorial de la salud para nuestro hoy.
La irrupción de la "teología política" en la República de Weimar y sus reverberaciones contemporánea
Guerrero Apráez,Víctor;
Papel Politico , 2008,
Abstract: so called political theology originated and developed in the seminal works of carl schmitt and walter benjamin during the tumultuous period of the weimarrepublic. under dramatic circumstances, both authors developed a defiant and original approach to the political and legal problems faced by the first democratic regime set up in germany , through which the question of the theological foundation and its implications for the theory and practice of politics arose in an unexpected way. the radically opposed positions adopted by benjamin and schmitt, demanding messianic revolution and exceptional counterrevolution, have exerted a rich and polemic influence in a broad set of the most influential political thinkers of the last century and the new millennium. political theologies are currently a vigorous academic field and are also part of the discipline of political studies. this essay explores the reasons for this new trend and the challenges it poses for politics as well as its contribution to the perspective of the victims.
Estrategias de ruptura política, absolutización del enemigo y conversión ideológica en Rafael Nú?ez y álvaro úribe

Papel Politico , 2011,
Abstract: the strategies implemented by two presidents whose governments are so distant from a chronological point of view like those of alvaro uribe (2002-2010) and rafael nú?ez (1884-1894) in colombia, show notwhistanding, amazing points of contact and programmatic also ideological rapprochements through the attempt to build up by the way of a new foundation a state organization made by each one which final result was the deep partition between the after and before of both presidential terms accompanied with radical and contested transformations. employing classic and innovative political tools like biopolitics (roberto esposito), sharpening of political rivalry (schmitt) and political conversion (badiou) the focus of these analytical and comparative essay on the so called 'regeneration' of the one side, and the democratic security/communal state, of the other, both considered as biopolitical concepts, the fight against the liberal radicalism at the end of nineteenth century and the war against the farc, also the ideological wandering from his ancient party to the opposite and rival political community in both cases, allow to understand two complementary tactics used by both presidents: the undermining of the constitution and the upgrading of civil war as way of government.

Abstract: Feeding systems for dairy ruminants need to ensure high intake of energy to achieve maximum milk production potential. This might be accomplished by raising the dietary concentration of cereal grain. Increasing the concentration of starch in diets can lead to undesirable ruminal fermentation, and to prevent it, the partial replacement of cereal grain with low starch by-product feeds is recommended. The purpose of the present study was to compare the effect of fed two mixed diets to dairy goats differing in the type of carbohydrate (starch vs. easily degradable fiber). Energy and nitrogen balance, short chain fatty acids in rumen liquor and milk performance in dairy goats during mid lactation were determined. Enteric methane (CH4) emissions and CH4 production from manure were determined as well. Ten multiparous Muciano-Granadina goats were assigned to two isoenergetic and isoproteic diets (19.1 MJ/kg dry matter (DM) and 18.1% of CP, DM basis) in a crossover design. One group was fed a mixed ration with 21.9% of starch (HS diet) and the other (LS diet) with 7.0% of starch. HS diet had 36% of barley (as source of starch) and it was replaced with soy hulls and corn gluten feed in LS diet (as potentially digestible fiber). No differences were observed for dry matter intake in both diets (2.05 kg/d, on average). A significant increase of ruminal acetic acid was found for low starch diet (66.4 and 56.6 mol/100 mol for LS and HS diet, respectively). No significant effect was found among diets for enteric CH4 emissions (28.5 g/d, on average). Manure derived maximum potential yield was (Bo) higher in HS diet, with 5.9 L CH4/kg OM vs. 0.28 L CH4/kg OM for LS diet, probably associated with the low ADF digestibility. Differences among diets were found for milk production (2.4 vs. 2.2 kg/d for HS and LS, respectively), and greater milk fat was observed with LS diet compared with HS (6.4% vs. 5.5%, respectively).

Historia Crítica , 2000,
Abstract: Este artículo busca aproximar las relaciones Jerárquicas que existían en los hogares de la elite santafere a durante el siglo XIX, a partir de los diferentes recintos que constituían el espacio doméstico, buscando hacer evidente que las relaciones que se establecían con el entorno, no eran neutras; por el contrario, en parte, reflejaban lo que ocurría socialmente entre quienes habitaban sus viviendas.
