Espacios públicos diferenciados en la Ciudad de México: una mirada desde el lugar

Neste trabalho interessa-me aprofundar a ideia de que o espaço público não é uno, mas que há diversas categorizações dos espaços públicos urbanos quanto à ordem, às formas de apropriação e à significação que lhes outorgam os distintos grupos sociais que os produzem, reproduzem e usam. Estas diversas categorizações dependerão de variáveis históricas, socioeconômicas e culturais, a partir das quais se podem construir tipologias do público. Esta reflexão se baseia no caso da Cidade do México.This work aims to enhance the idea that public space is not unitary, but there are several categorizations of urban public space regarding order, appropriation forms and meanings attributed to it by the distinct social groups that produces, reproduces and uses such spaces. These different categorizations depends upon historical, socioeconomic and cultural variables, from which it is possible to build public typologies. This reflexion is bases on Mexico City case

The belives on the asphalt. Sacred sites as means of appropriation of the public space in México City

En este trabajo me interesa explorar una de las formas en que los habitantes de la ciudad de México se apropian del espacio público urbano, a partir de la sacralización de lugares específicos en la vía pública. Dicha apropiación se hace visible con la instalación de altares, cruces para sus muertos y nichos para vírgenes y santos. Estos elementos de la religiosidad popular se conforman no sólo en parte del paisaje urbano, sino que tienen una función cotidiana –articulada a la protección, a la construcción de memoria y al manejo de los espacios liminales– en una ciudad aparentemente caótica, en donde los espacios públicos se consideran “en extinción”. Son elementos que buscan poblar con rostros y nombres propios el espacio del anonimato urbano, generando lugares de sentido y de memoria para los pobladores locales. De esta manera, el espacio público se constituye en una suerte de escenario en donde lo más personal de los sujetos y los grupos se hace visible.This paper explores how residents of México City appropriate public spaces by transforming local places into sacred sites.  This sacred quality is achieved by installing crucifixes, altars and niches for virgins and saints.  These symbols of folk religion not only adorn public sites, but also offer protection, serve as mnemonic devices and manage spatial liminality -all this in a chaotic city where public spaces are considered to be almost extinct.  These elements -- faces, proper names, common religious symbols- mark “anonymous” urban spaces, generating meaning and memory for inhabitants.  In this fashion, public spaces become a scenario for projecting personal elements of  neighborhood groups

Las creencias en el asfalto

This paper explores how residents of México City appropriate public spaces by transforming local places into sacred sites. This sacred quality is achieved by installing crucifixes, altars and niches for virgins and saints. These symbols of folk religion not only adorn public sites, but also offer protection, serve as mnemonic devices and manage spatial liminality -all this in a chaotic city where public spaces are considered to be almost extinct.

El espacio urbano y la construcción de lo público: reflexiones en torno a lo público en el barrio de La Fama, Tlalpan

La discusión en torno a lo público y lo privado adquiere vigencia, en la medida que es necesario para las ciencias sociales dar cuenta de los procesos urbanos de lucha, apropiación, significación y organización del espacio. Ello representa uno de los aspectos más álgidos de la convivencia social, especialmente en ciudades como México, en la que cada centímetro de terreno tiene un enorme valor simbólico, político, monetario y de subsistencia. En este contexto, en este trabajo se pretende explorar a partir del caso concreto del barrio de La Fama en Tlalpan, D.F., las transformaciones de lo público y lo privado y su relación con el conjunto de la ciudad de México. Analizando ¿cómo se construye un espacio barrial específico? ¿Cómo incide este proceso histórico en la comprensión actual de lo público y lo privado, ¿De qué manera esta comprensión genera tensiones sociales y conflictos locales? El territorio urbano, significado y apropiado de manera desigual, se constituye en el eje de la vida social urbana, reimaginado, fragmentado y reconstituido por los medios masivos de comunicación, pero siempre como referente fundamental. Par a analizar estos aspectos hemos dividido el trabajo en tres partes: en la primera hacemos ciertas consideraciones teóricas y proponemos algunas aproximaciones para comprender la construcción espacial de la urbe. En la segunda, reconstruimos la historia del barrio desde la perspectiva del uso de lo público y lo privado, con el fin de comprender de dónde viene el concepto de "público" y qué sentido tiene en la actualidad. Finalmente, se analizan algunos de los problemas actuales por los que atraviesa el barrio y sus implicaciones como parte de la ciudad

SPIRE Point Source Catalog Explanatory Supplement

The Spectral and Photometric Imaging Receiver (SPIRE) was launched as one of the scientific instruments on board of the space observatory Herschel. The SPIRE photometer opened up an entirely new window in the Submillimeter domain for large scale mapping, that up to then was very difficult to observe. There are already several catalogs that were produced by individual Herschel science projects. Yet, we estimate that the objects of only a fraction of these maps will ever be systematically extracted and published by the science teams that originally proposed the observations. The SPIRE instrument performed its standard photometric observations in an optically very stable configuration, only moving the telescope across the sky, with variations in its configuration parameters limited to scan speed and sampling rate. This and the scarcity of features in the data that require special processing steps made this dataset very attractive for producing an expert reduced catalog of point sources that is being described in this document. The Catalog was extracted from a total of 6878 unmodified SPIRE scan map observations. The photometry was obtained by a systematic and homogeneous source extraction procedure, followed by a rigorous quality check that emphasized reliability over completeness. Having to exclude regions affected by strong Galactic emission, that pushed the limits of the four source extraction methods that were used, this catalog is aimed primarily at the extragalactic community. The result can serve as a pathfinder for ALMA and other Submillimeter and Far-Infrared facilities. 1,693,718 sources are included in the final catalog, splitting into 950688, 524734, 218296 objects for the 250\mu m, 350\mu m, and 500\mu m bands, respectively. The catalog comes with well characterized environments, reliability, completeness, and accuracies, that single programs typically cannot provide

Parathyroid hormone-related protein (107-111) improves the bone regeneration potential of gelatin-glutaraldehyde biopolymer-coated hydroxyapatite

Biopolymer-coated nanocrystalline hydroxyapatite (HA) made as macroporous foams which are degradable and flexible are promising candidates as orthopaedic implants. The C-terminal (107-111) epitope of parathyroid hormone-related protein (PTHrP) exhibits osteogenic properties. The main aim of this study was to evaluate whether PTHrP (107-111) loading into gelatin-glutaraldehyde biopolymer-coated HA (HA(GIu)) scaffolds would produce an optimal biomaterial for tissue engineering applications. HA(GIu) scaffolds with and without PTHrP (107-111) were implanted into a cavitary defect performed in both distal tibial metaphysis of adult rats. Animals were sacrificed after 4 weeks for histological, microcomputerized tomography and gene expression analysis of the callus. At this time, bone healing occurred only in the presence of PTHrP (107-111)-containing HA(Giu) implant, related to an increase in bone volume/tissue volume and trabecular thickness, cortical thickness and gene expression of osteocalcin and vascular cell adhesion molecule I, but a decreased gene expression of Wnt inhibitors, SOST and dickkopf homolog 1. The autonomous osteogenic effect of the PTHrP (107-111)-loaded HA(Giu) scaffolds was confirmed in mouse and human osteoblastic cell cultures. Our findings demonstrate the advantage of loading PTHrP (107-111) into degradable HA(GIu) scaffolds for achieving an optimal biomaterial that is promising for low load bearing clinical applications.

Lyman break and ultraviolet-selected galaxies at z ~ 1 - II. PACS 100μm/160μm FIR detections

In this work, we report the Photodetector Array Camera and Spectrometer (PACS) 100 μm/160 μm detections of a sample of 42 GALEX-selected and far-infrared (FIR)-detected Lyman break galaxies (LBGs) at z ~ 1 located in the Cosmic Evolution Survey (COSMOS) field and analyse their ultraviolet (UV) to FIR properties. The detection of these LBGs in the FIR indicates that they have a dust content high enough so that its emission can be directly detected. According to a spectral energy distribution (SED) fitting with stellar population templates to their UV-to-near-IR observed photometry, PACS-detected LBGs tend to be bigger (Reff ~ 4.1 kpc), more massive [log (M*/M⊙) ~ 10.7], dustier [Es(B - V) ~ 0.40], redder in the UV continuum (β ~ -0.60) and UV-brighter [log (LUV/L⊙) ~ 10.1] than PACSundetected LBGs. PACS-detected LBGs at z ~ 1 are mostly disc-like galaxies and are located over the green valley and red sequence of the colour-magnitude diagram of galaxies at their redshift. By using their UV and IR emission, we find that PACS-detected LBGs tend to be less dusty and have slightly higher total star formation rates (SFRs) than other PACS-detected UV-selected galaxies within the same redshift range. As a consequence of the selection effect due to the depth of the FIR observations employed, all our PACS-detected LBGs have total IR luminosities, LIR, higher than 1011 L⊙ and thus are luminous IR galaxies. However, none of the PACS-detected LBGs are in the ultra-luminous IR galaxy (ULIRG) regime, LIR =1012 L⊙, where the FIR observations are complete. The finding of ULIRGs-LBGs at higher redshifts (z ~ 3) suggests an evolution of the FIR emission of LBGs with cosmic time. In an IRX-β diagram, PACS-detected LBGs at z~1 tend to be located around the relation for local starburst similarly to other UV-selected PACS-detected galaxies at the same redshift. Consequently, the dust-correction factors obtained with theirUVcontinuum slope allowus to determine their total SFR, unlike at higher redshifts. However, the dust attenuation derived from UV to NIR SED fitting overestimates the total SFR for most of our PACS-detected LBGs in an age-dependent way: the overestimation factor is higher in younger galaxies. This is likely due to the typical degeneracy between dust attenuation and age in the SED fitting with synthetic templates and highlights the importance of the FIR measurements in the analysis of star-forming galaxies at intermediate redshifts.Generalitat Valenciana PROMETEO-2008/132NASA Office of Space Science NNX09AF08GEuropean Southern Observatory LP175.A-0839Junta de Andalucía TIC-114, P08-TIC-03531Ministerio de Economía y Competitividad AYA2011- 29517-C03-01, AYA2010-22111-C03-02, AYA2010-1516

A morphological study of galaxies in ZwCl0024+1652, a galaxy cluster at redshift z ∼ 0.4

ABSTRACT: he well-known cluster of galaxies ZwCl0024+1652 at z ∼ 0.4 lacks an in-depth morphological classification of its central region. While previous studies provide a visual classification of a patched area, we used the public code called galaxy Support Vector Machine GALSVM) and HST/ACS data as well as the WFP2 master catalogue to automatically classify all cluster members up to 1 Mpc. GALSVM analyses galaxy morphologies through support vector machine (SVM). From the 231 cluster galaxies, we classified 97 as early types (ETs) and 83 as late types (LTs). The remaining 51 stayed unclassified (or undecided). By cross-matching our results with the existing visual classification, we found an agreement of 81 per cent. In addition to previous Zwcl0024 morphological classifications, 121 of our galaxies were classified for the first time in this work. In addition, we tested the location of classified galaxies on the standard morphological diagrams, colour–colour and colour–magnitude diagrams. Out of all cluster members, ∼20 per cent are emission-line galaxies, taking into account previous GLACE results. We have verified that the ET fraction is slightly higher near the cluster core and decreases with the clustercentric distance, while the opposite trend has been observed for LT galaxies. We found a higher fraction of ETs (54 per cent) than LTs (46 per cent) throughout the analysed central region, as expected. In addition, we analysed the correlation between the five morphological parameters (Abraham concentration, Bershady–Concelice concentration, asymmetry, Gini, and M20 moment of light) and the clustercentric distance, without finding a clear trend. Finally, as a result of our work, the morphological catalogue of 231 galaxies containing all the measured parameters and the final classification is available in the electronic form of this paper.MP also acknowledges support from the Spanish MINECO under projects AYA2013-42227-P and AYA2016-76682-C3-1-P- This work was supported by the Spanish Ministry of Economy and Competitiveness (MINECO) under the grants AYA2014-58861-C3-2-P, AYA2014-58861-C3-3-P, AYA2017-88007-C3-1-P, and AYA2017-88007-C3-2-P
