In architecture: Absent, invisible, supplanted

It is not a frequent theme in architectural literature, to talk about women historical place. Talking about gender equality, Architecture lags behind other Knowledge and human activity areas, whether architect or user, so Architecture History from the Renaissance to the Modern Movement, almost lacks feminine referents. In this article, I will try to demonstrate the androcentrism of the Architectural Classical Theory works, as well as those from the Modern Movement and its persistence today. I will also illustrate the patriarchal women invisibilization in both the profession and in the use of the work.No es un tema frecuente en la literatura de ámbito arquitectónico, hablar del lugar que han ocupado las mujeres históricamente en él. La arquitectura va a la zaga de otras áreas del conocimiento y de la actividad humana, en lo referente al tratamiento igualitario de la mujer, bien sea arquitecta o usuaria, por lo que la historia de la arquitectura desde el Renacimiento hasta el Movimiento Moderno, casi carece de referentes femeninas. En este artículo, trataré de demostrar el androcentrismo de las obras clásicas de la teoría arquitectónica, así como de las del Movimiento Moderno y su persistencia en la actualidad. También ilustraré la invisibilización patriarcal de las mujeres tanto en la profesión como en el uso de la obra

Tratamiento de los Juegos Paralímpicos por parte de los medios de comunicación : Ambición y coraje en los Paralímpicos de Río 2016

El presente reportaje expone la situación del deporte adaptado en los medios de comunicación. A pesar de estar más centrado en los Juegos Paralímpicos, los abajo entrevistados expresan su opinión sobre la falta de información en todos los medios. Las noticias analizadas para llevar a cabo este reportaje y las entrevistas demostrarán que el periodismo deportivo aún tiene mucho que hacer.Universidad de Sevilla. Grado en Periodism

Orbescrito.org : Cartografía latinoamericana de archivos de escritores

El trabajo recorre los inicios del diseño y puesta en marcha de Orbescrito.org, portal web que se propone la recolección y reunión de información acerca de la existencia y localización de manuscritos de escritores latinoamericanos. El desarrollo de esta herramienta, estructurada como un directorio y en su doble función de difusor y gestor de contenidos, busca dar libre acceso a esa información. Se busca así elaborar una cartografía latinoamericana de archivos de escritores en respuesta a las necesidades de información de los investigadores del área de las Letras y de la Crítica Genética en pos de contribuir, desde la bibliotecología, a la localización y preservación del patrimonio cultural latinoamericanoFil: Calvente, Victoria.

The distribution of old stars around the Milky Way's central black hole I: Star counts

(abridged) In this paper we revisit the problem of inferring the innermost structure of the Milky Way's nuclear star cluster via star counts, to clarify whether it displays a core or a cusp around the central black hole. Through image stacking and improved PSF fitting we push the completeness limit about one magnitude deeper than in previous, comparable work. Contrary to previous work, we analyse the stellar density in well-defined magnitude ranges in order to be able to constrain stellar masses and ages. The RC and brighter giant stars display a core-like surface density profile within a projected radius R<0.3 pc of the central black hole, in agreement with previous studies, but show a cusp-like surface density distribution at larger R. The surface density of the fainter stars can be described well by a single power-law at R<2 pc. The cusp-like profile of the faint stars persists even if we take into account the possible contamination of stars in this brightness range by young pre-main sequence stars. The data are inconsistent with a core-profile for the faint stars.Finally, we show that a 3D Nuker law provides a very good description of the cluster structure. We conclude that the observed stellar density at the Galactic Centre, as it can be inferred with current instruments, is consistent with the existence of a stellar cusp around the Milky Way's central black hole, Sgr A*. This cusp is well developed inside the influence radius of about 3 pc of Sgr A* and can be described by a single three-dimensional power-law with an exponent gamma=1.23+-0.05. The apparent lack of RC stars and brighter giants at projected distances of R < 0.3 pc (R<8") of the massive black hole may indicate that some mechanism has altered their distribution or intrinsic luminosity.Comment: Accepted for publication A&

Near-Infrared Variability Study of the Central 2.3 arcmin x 2.3 arcmin of the Galactic Centre II. Identification of RR Lyrae Stars in the Milky Way Nuclear Star Cluster

Because of strong and spatially highly variable interstellar extinction and extreme source crowding, the faint (K>15) stellar population in the Milky Way's nuclear cluster is still poorly studied. RR Lyrae stars provide us with a tool to estimate the mass of the oldest, relative dim stellar population. Recently, we analyzed HST/WFC3/IR observations of the central 2.3'x2.3' of the Milky Way and found 21 variable stars with periods between 0.2 and 1d. Here, we present a further comprehensive analysis of these stars. The period-luminosity relationship of RR Lyrae is used to derive their extinctions and distances. Using multiple approaches, we classify our sample as four RRc, four RRab and three candidates, ten binaries. Especially, the four RRabs show sawtooth light curves and fall exactly onto the Oosterhoff I division in the Bailey diagram. Compared to the RRabs reported by Minniti et al, 2016, our new RRabs have higher extinction (A_K>1.8) and should be closer to the Galactic Centre. The extinction and distance of one RRab match those for the nuclear star cluster given in previous works. We perform simulations and find that after correcting for incompleteness, there could be no more than 40 RRabs within the nuclear star cluster and in our field-of-view. Through comparing with the known globular clusters of the Milky Way, we estimate that if there exists an old, metal-poor (-1.5<[Fe/H]<-1) stellar population in the Milky Way nuclear star cluster on a scale of 5x5pc, then it contributes at most 4.7x10^5 solar mass, i.e., ~18% of the stellar mass.Comment: 33 pages, 10 figures.
