La imagen y la narrativa como instrumentos de la acción psicosocial en escenarios de violencia. Departamento del Meta

Los impactos o efectos que deja el conflicto armado hacen necesario que haya una comprensión desde una perspectiva psicosocial, en la que se profundice las diferentes variables que surgen dentro de los escenarios de violencia. Entre ellas, los relatos, las imágenes, las dinámicas sociales y los elementos simbólicos que han sido construidos desde los lugares y por las personas víctimas de estos flagelos. Desde el presente se hace un análisis a partir de eventos o situaciones traumáticas sufridas durante la violencia en nuestro país, procurando examinar y estudiar desde una visión como futuros psicólogos, estableciendo una posición concreta y congruente con el marco teórico y metodológico que promueve lo psicosocial. Se emplea así un análisis reflexivo al relato de Alfredo Campos, a través de una serie de interrogantes se debate y de manera colaborativa se reconocen aspectos subjetivos, impactos psicosociales, efectos de la violencia, posturas resilientes, y se formulan también preguntas circulares, reflexivas y estratégicas que permiten hacer un acercamiento al caso. Se aborda una propuesta desde lo psicosocial sustentada desde el enfoque narrativo Michael White (2003), donde a través del caso Peñas Coloradas se aborda una reflexión teniendo en cuenta ciertos ítems sobre el caso, entre estas las acciones y estrategias en la situación de crisis presentada. Por tanto, se hace construcción del producto final con los insumos logrados por el grupo. La interpretación de los casos relatados sobre el conflicto armado y sus consecuencias permiten ver episodios desde un punto de vista analítico y reflexivo del dolor; los abusos, calumnias, miedos, violencia, muertes, asesinatos, secuestros, que están sometidos a vivir y a huir.The impacts or effects left by the armed conflict make it necessary to have an understanding from a psychosocial perspective, in which the different variables that arise within the scenarios of violence are studied. Among them, the stories, images, social dynamics, and symbolic elements that have been constructed from the places and by the people who have been victims of these scourges. From the present, an analysis is made from events or traumatic situations suffered during the violence in our country, trying to examine and study from a vision as future psychologists, establishing a concrete and congruent position with the theoretical and methodological framework that promotes the psychosocial. A reflective analysis of Alfredo Campos' story is thus employed, through a series of questions and debates, and in a collaborative manner, subjective aspects, psychosocial impacts, effects of violence, resilient postures, and circular, reflective, and strategic questions are also formulated that allow for an approach to the case. A psychosocial approach based on the narrative approach of Michael White (2003), where through the Peñas Coloradas case, a reflection is approached taking into account certain items about the case, among these the actions and strategies in the crisis situation presented. Therefore, the final product is constructed with the inputs obtained by the group. The interpretation of the cases related to the armed conflict and its consequences allows to see episodes from an analytical and reflective point of view of the pain; the abuses, slander, fears, violence, deaths, murders, kidnappings, which they are subjected to live and flee

<i>Gaia</i> Data Release 1. Summary of the astrometric, photometric, and survey properties

Context. At about 1000 days after the launch of Gaia we present the first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magnitude 20.7. Aims. A summary of Gaia DR1 is presented along with illustrations of the scientific quality of the data, followed by a discussion of the limitations due to the preliminary nature of this release. Methods. The raw data collected by Gaia during the first 14 months of the mission have been processed by the Gaia Data Processing and Analysis Consortium (DPAC) and turned into an astrometric and photometric catalogue. Results. Gaia DR1 consists of three components: a primary astrometric data set which contains the positions, parallaxes, and mean proper motions for about 2 million of the brightest stars in common with the HIPPARCOS and Tycho-2 catalogues – a realisation of the Tycho-Gaia Astrometric Solution (TGAS) – and a secondary astrometric data set containing the positions for an additional 1.1 billion sources. The second component is the photometric data set, consisting of mean G-band magnitudes for all sources. The G-band light curves and the characteristics of ∼3000 Cepheid and RR-Lyrae stars, observed at high cadence around the south ecliptic pole, form the third component. For the primary astrometric data set the typical uncertainty is about 0.3 mas for the positions and parallaxes, and about 1 mas yr−1 for the proper motions. A systematic component of ∼0.3 mas should be added to the parallax uncertainties. For the subset of ∼94 000 HIPPARCOS stars in the primary data set, the proper motions are much more precise at about 0.06 mas yr−1. For the secondary astrometric data set, the typical uncertainty of the positions is ∼10 mas. The median uncertainties on the mean G-band magnitudes range from the mmag level to ∼0.03 mag over the magnitude range 5 to 20.7. Conclusions. Gaia DR1 is an important milestone ahead of the next Gaia data release, which will feature five-parameter astrometry for all sources. Extensive validation shows that Gaia DR1 represents a major advance in the mapping of the heavens and the availability of basic stellar data that underpin observational astrophysics. Nevertheless, the very preliminary nature of this first Gaia data release does lead to a number of important limitations to the data quality which should be carefully considered before drawing conclusions from the data

Photoreceptor glucose metabolism determines normal retinal vascular growth

Abstract The neural cells and factors determining normal vascular growth are not well defined even though vision‐threatening neovessel growth, a major cause of blindness in retinopathy of prematurity (ROP) (and diabetic retinopathy), is driven by delayed normal vascular growth. We here examined whether hyperglycemia and low adiponectin (APN) levels delayed normal retinal vascularization, driven primarily by dysregulated photoreceptor metabolism. In premature infants, low APN levels correlated with hyperglycemia and delayed retinal vascular formation. Experimentally in a neonatal mouse model of postnatal hyperglycemia modeling early ROP, hyperglycemia caused photoreceptor dysfunction and delayed neurovascular maturation associated with changes in the APN pathway; recombinant mouse APN or APN receptor agonist AdipoRon treatment normalized vascular growth. APN deficiency decreased retinal mitochondrial metabolic enzyme levels particularly in photoreceptors, suppressed retinal vascular development, and decreased photoreceptor platelet‐derived growth factor (Pdgfb). APN pathway activation reversed these effects. Blockade of mitochondrial respiration abolished AdipoRon‐induced Pdgfb increase in photoreceptors. Photoreceptor knockdown of Pdgfb delayed retinal vascular formation. Stimulation of the APN pathway might prevent hyperglycemia‐associated retinal abnormalities and suppress phase I ROP in premature infants
