In the contemporary world, especially within the digital universe, conceptualizing the subject constituted in this reality is a mandatory exercise. A reflection on the matter, being especially careful of universalizing intentions is necessary. This research work aims to a view that breaks the separation between what is real as an external aspect and subjectivity, in order to redefine the idea of objectivity related to formation. Therefore, from the method provided by hermeneutics as a way for interpretation, the article tries to approach subjectivity without any operative positions taken from the positivist reductions and also without the bold locution of macro historical processes defined by the digital world. This is a reflection funded on the contents that appear in the historical and transience conditions of the subjects, remarking the emergence non-hegemonic social relationships.

Cambios genéticos temporales y microgeográficos de Aedes aegypti en Medellín, Colombia Microgeographic and temporal genetic changes of Aedes aegypti from Medellín, ColombiaIntroduction: Aedes aegypti populations may experience changes in abundance and genetic diversity in addition to changes in their evolutionary capability to respond to vector control. The knowledge on the changes in genetic variation on a spatio-temporal scale improves the epidemiological understanding of dengue and supports the appropriate and timely design of vector control strategies. Objective: To assess the genetic changes, diversity and gene flow in six microgeographical populations of Ae. aegypti in Medellín for different epidemiological periods of dengue. Materials and methods: A total of 255 specimens from six different neighborhoods in Medellín were used to assess variations in the CO1 mtDNA haplotype composition, diversity and genetic differentiation for an epidemic period (2010) and an endemic period (2012). Results: Two groups of highly differentiated haplotypes were present in both periods, and a highfrequency haplotype was assessed for all neighborhoods. The highest haplotype diversity was recorded in 2012, but the maximum nucleotide diversity was recorded in 2010. No significant correlation between genetic and geographic distances was observed. Conclusions:The genetic composition of Ae. aegypti varies over time without a predictable pattern. In addition, the presence of a high-frequency haplotype in both periods could indicate a persistent variation adapted to vector control. However, the simultaneous movement of highly differentiated CO154 Biomédica 2015;35:53-61 Cadavid JM, Rúa G, Campo O, et al. haplotypes compatible with multiple introductions suggests that different gene pools would be suitable for transmission. These results are consistent with mosquito dispersion due to human activities, which would enable the rapid spread of the virus during epidemics in Medellin.
En este artículo se hace un rastreo de las principales tendencias de la poesía colombiana entre 1990-2012, con el propósito de distinguir los rasgos de estilo y de contenido que definen estas nuevas voces poéticas y sus vínculos con las generaciones precedentes. También pretende explorar los puntos de contacto que los jóvenes poetas colombianos han tenido con la vanguardia y la postmodernidad. Cinco tendencias marcan a estos poetas de finales del siglo XX y principios del XXI: tendencia crítica y autoirónica, clásica, barroca, prosaico narrativa y filosófica. Finalmente, se reflexiona acerca del impacto que estas tendencias han tenido en algunos de los más representativos poetas del periodo estudiado.
En el contexto de las instituciones latinoamericanas, la enseñanza sigue siendo cuestionada sobre las posibilidades para convertir la vida cotidiana un espacio permanente de darse y dar cuenta de dónde, por qué y para qué de la realidad subjetiva, y por ende social. Así pues, este trabajo presenta ideas en torno a una didáctica que lee expresiones de cualquier tipo, en su contenido explícito o implícito; una didáctica que asume de alguna manera las lógicas de razonamiento con las que se construye la realidad, que no están sujetas a parámetros. En los parámetros, en los límites hace presencia la colonialidad del saber y del poder, que garantizan la constitución del sujeto y su subjetividad, desde razonamientos introyectados. Por ello, la problematización como método es vital en los espacios de reflexión, es provocación a una potencia que da sentido a la existencia, construir conocimiento como conciencia, no es digerir para asimilar la información como verdad absoluta.
