Una realidad social escindida: Las memorias de las peras y las manzanas en el Chile reciente
2014
Forty years after the military coup that bloodied Chile during the years of military dictatorship, the country is still splitted with a society which is still in a traumatic situation. In this paper we have worked with audio-visual sources, which we call Video Format Documents (VFD), produced from the sixties onwards. This article is based on sources that allow us a deeper understanding of the society in which they were produced; a society −as it is said by a character of one of the most successful films in Chile−, divided into pears and apples.
De los detalles al todo: historia cultural y biografías globales
2013
Este artículo aborda algunas de las nuevas direcciones de la historia cultural. En particular, los trabajos de algunos estudiosos que emplean una perspectiva global. Esa elección plantea algunos problemas, sobre todo los relativos a las aparentes contradicciones entre la tradicional mirada micro, que ha sido característica de la historia cultural más significativa, y la macro, en la que acostumbraba a primar el análisis económico o político. ¿Cómo analizar un individuo desde una perspectiva global? Utilizando principalmente las reflexiones de Peter Burke o Natalie Zemon Davis, el artículo expone que esa preocupación es un asunto actual, propio de una época de interconexión acelerada, que re…
Trauma y denuncia en los testimonios del exilio chileno
2009
El artículo analiza el rol cumplido por los testimonios que los supervivientes de los campos de concentración chilenos publicaron en el exilio en los años siguientes al golpe de estado de 1973, que dio origen a la dictadura de Pinochet. El artículo se centra en dos elementos principales. Por una parte, el papel de los testimonios en las estrategias de denuncia internacional contra la dictadura. Por otra, el modo en que los supervivientes utilizaron la escritura testimonial para elaborar y dar un sentido narrativo al trauma experimentado en los campos de concentración. The article analizes the role accomplished by the testimonies of survivors of concentration camps in Chile, wich were publis…
¿Que Historia de España Enseñar?
2005
España representa mucho más que un término para designar un lugar en el mapa o una mera “superestructura” política sustentada en exclusiva por ideas y voluntades. Producto cultural humano, resulta por encima de todo un hecho histórico colectivo, de larga duración, contingente, variable, complejo y problemático, de una entidad y trascendencia que llegan hasta nuestros días. Al igual que cualquier otro hecho histórico, requiere de la historia para entenderlo en sus distintas dimensiones. Por ello, nada tiene de extraño que la historia de España sea a partir de cierta edad una materia básica del currículo de los estudiantes en la enseñanza secundaria obligatoria y continúe como tal en los dist…
Gene expression of stem cells at different stages of ontological human development.
2013
Abstract Objectives To compare multipotent mesenchymal stem cells (MSCs) obtained from chorionic villi (CV), amniotic fluid (AF) and placenta, with regard to their phenotype and gene expression, in order to understand if MSCs derived from different extra-embryonic tissues, at different stages of human ontological development, present distinct stemness characteristics. Study design MSCs obtained from 30 samples of CV, 30 of AF and 10 placentas (obtained from elective caesarean sections) were compared. MSCs at second confluence cultures were characterized by immunophenotypic analysis with flow cytometry using FACS CANTO II. The expression of the genes Oct-4 (Octamer-binding transcription fact…
Zfp819, a novel KRAB-zinc finger protein, interacts with KAP1 and functions in genomic integrity maintenance of mouse embryonic stem cells
2013
AbstractPluripotency is maintained by both known and unknown transcriptional regulatory networks. In the present study, we have identified Zfp819, a KRAB-zinc finger protein, as a novel pluripotency-related factor and characterized its role in pluripotent stem cells. We show that Zfp819 is expressed highly in various types of pluripotent stem cells but not in their differentiated counterparts. We identified the presence of non-canonical nuclear localization signals in particular zinc finger motifs and identified them as responsible for the nuclear localization of Zfp819. Analysis of the Zfp819 promoter region revealed the presence of a transcriptionally active chromatin signature. Moreover,…
Depth Enhancement by Fusion for Passive and Active Sensing
2012
This paper presents a general refinement procedure that enhances any given depth map obtained by passive or active sensing. Given a depth map, either estimated by triangulation methods or directly provided by the sensing system, and its corresponding 2-D image, we correct the depth values by separately treating regions with undesired effects such as empty holes, texture copying or edge blurring due to homogeneous regions, occlusions, and shadowing. In this work, we use recent depth enhancement filters intended for Time-of-Flight cameras, and adapt them to alternative depth sensing modalities, both active using an RGB-D camera and passive using a dense stereo camera. To that end, we propose …
The Wide Field Imager instrument for Athena
2017
ESA's next large X-ray mission ATHENA is designed to address the Cosmic Vision science theme 'The Hot and Energetic Universe'. It will provide answers to the two key astrophysical questions how does ordinary matter assemble into the large-scale structures we see today and how do black holes grow and shape the Universe. The ATHENA spacecraft will be equipped with two focal plane cameras, a Wide Field Imager (WFI) and an X-ray Integral Field Unit (X-IFU). The WFI instrument is optimized for state-of-The-Art resolution spectroscopy over a large field of view of 40 amin x 40 amin and high count rates up to and beyond 1 Crab source intensity. The cryogenic X-IFU camera is designed for high-spect…
Narkotiku nozīme Alena Ginsberga dzejolī "Kauciens" (1956)
2022
Šis darbs ir vērsts uz narkotiku nozīmes izpēti Alena Ginsberga dzejolī "Kauciens "(1956), kā arī Beat Paaudzi un narkotiku vēsturi Amerikas pēckara sabiedrībā un metaforu izmantošanu simbolikas literatūrā. Šī darba mērķis ir rūpīgi izpētīt teoriju par metaforām, kā arī teoriju par simboliku un izmantot šo teoriju, lai iegūtu metaforas, ko izmanto, lai runātu par narkotikām Alena Ginsberga dzejā, noteiktu šo metaforu nozīmi un izdarītu secinājumus. Analīze ir parādījusi, ka narkotikas "Kauciens" (1956) ir metafora augstākam redzējumam, apgaismotai realitātei, kuru cilvēks var sasniegt, lietojot vielas. Dzejolis parāda pilnu ceļojumu no pirmās narkotiku ekstazī līdz izmisīgajai vajadzībai pē…
