Notas para una historia de la desnutrición en la Iberoamérica del siglo XX

El trabajo analiza los principales determinantes y las características de la desnutrición en América Latina durante la segunda mitad del siglo XX. En primer lugar, se explican las bases del problema moderno del hambre y la desnutrición, tanto en su dimensión fisiológica como social, al destacarse su condición de calamidad social y de expresión biológica del subdesarrollo y de las desigualdades sociales. En segundo lugar, a partir de testimonios contemporáneos, se exponen las principales características de la desnutrición que ha afectado a la población iberoamericana, y las causas que la explican. Por último, a modo de conclusión, se subrayan las consecuencias negativas de no haber aprovechado la oportunidad que conllevaba el reto de superar los factores condicionantes de la malnutrición por defecto, y haber finalizado el siglo XX con un panorama epidemiológico nutricional donde los problemas del hambre y la desnutrición conviven con fenómenos como los de la obesidad de la pobreza.

El reto y la oportunidad de acabar con el hambre: reflexiones desde la obra de José María Bengoa Lecanda (1913-2010)

El trabajo aborda, a través de la obra de José María Bengoa Lecanda (1913-2010), la condición de intolerable social que alcanzó, a lo largo del siglo XX, el problema del hambre y la desnutrición. Así mismo, intenta mostrar la oportunidad que comportaba dicho reto, si como parecía razonable, se trataba de corregir los factores condicionantes que estaban detrás del hambre y la desnutrición, en particular la pobreza y la falta de equidad.

Recolonization of mortars by endolithic organisms on the walls of San Roque church in Campeche (Mexico): A case of tertiary bioreceptivity

San Roque church (Campeche, Mexico) was built at the end of the 17th century with a micritic limestone and lime mortar in baroque style. In 2005 the church exhibited heavy biodeterioration associated with the development of extensive dark green phototrophic-based biofilms. Several cyanobacteria belonging to the order Chroococcales and lichenized fungi (Toninia nordlandica, Lobaria quercizans, Lecanora subcarnea, Cystocoleus ebeneus) were predominant in the dark biofilm samples, as revealed by DNA-based molecular techniques. In 2009, a cleaning and restoration intervention was adopted; however, after few months, microbial recolonization started to be noticeable on the painted church walls, representing an early phototrophic-based recolonization. According to molecular analysis, scanning electron microscopy observations and digital image analysis of cross sections, new phototrophic-based colonization, composed of cyanobacteria and bryophytes, developed mainly beneath the restored mortars. The intrinsic properties of the mortars, the tropical climate of Campeche and the absence of a biocide treatment in the restoration protocol influenced the recolonization of the church façades and enhanced the overall rate of deterioration in a short-term period.

"Paul and Mary are two people who are from different tribes and deeply in love. Their families share a close relationship and everything looks well for their wedding. However, with the out break of the post-election violence. Dr. Sawega, Paul's father, loses his clinic and his brother through arson. Stoked by politicians and tribalists, things get tense between the two families and the entire nation."--Spaceyangu.com.ar

Abandoned and forgotten: the sad story of Kenya's internally displaced persons

This documentary is about the internal displacement of ethnic minorities brought about by politically instigated post-election violence towards ethnic minorities in all eight provinces, namely, Coast, Rift Valley, Western, Eastern, North Eastern, Central Kenya, Nairobi, and Nyanza. During the years of 1991 to 1996, over 15,000 people died and almost 300,000 were displaced in the Rift Valley, Central, Nyanza and Western provinces. Before the 1997 elections, violence erupted. Again, following the disputed presidential elections in December 2007 politically and ethnically instigated displacements resulted in human rights violations against 600,000 people in 8 provinces of Kenya.
