Reflexiones docentes acerca del diseño arquitectónico de los centros de formación profesional en Granada

If the specificity of the architectural space is considered as a measuring element in the education scope to value the prominence of teaching throughout history, it is worth mentioning that the configuration of the vocational training center as a first-rate education scenario that arrives half century of delay with respect to schools, has few references of very specific period. At present, they continue excessively contaminated because of the continued struggle for linking them with other education levels. This article is focused on this issue. To that end, by interviewing experienced teachers, we value: a) from the most conceptual aspect, elements and architectural spaces that should have those reference centers; b) the appropriateness of the arranged spaces, not only those that meet the regulatory requirements but those that meet the criteria of the centers; c) to the most specific aspects on the way to optimize the arranged space in order to achieve a larger curricular extent. It concludes with a high positive assessment of the opportunity of having the necessary spaces for teaching, relying more strongly on those favoring the free relationship of students and allowing the permeability among the different disciplines that converge in the center.Si se toma como medidor la especificidad del espacio arquitectónico en el ámbito educativo para valorar el protagonismo que a lo largo de la historia han tenido las enseñanzas, cabe destacar que la configuración del centro docente para la formación profesional, como escenario educativo de primer orden, que llega con medio siglo de retraso respecto a las escuelas, cuenta con escasos referentes que responden a un periodo muy concreto y que, en la actualidad, persisten excesivamente contaminados debido a la continua puja por la vinculación de estas con otros niveles educativos. Esta cuestión es la temática en la que se centra el presente artículo. Para ello, y recurriendo a la entrevista de docentes con experiencia, se valora: a) desde lo más conceptual, elementos y espacios arquitectónicos que deben caracterizar los centros de referencia; b) la pertinencia de los espacios dispuestos, tanto los que responden a requerimientos reglamentarios como a los criterios de los propios centros; c) hasta los aspectos más concretos sobre la manera de optimizar el espacio dispuesto para alcanzar una mayor amplitud curricular. Se concluye con una valoración muy positiva de la oportunidad de espacios precisos para estas enseñanzas, apostando con fuerza por aquellos que propician la libre relación del alumnado y permiten la permeabilidad entre las distintas disciplinas que convergen en el centro.Si se toma como medidor la especificidad del espacio arquitectónico en el ámbito educativo para valorar el protagonismo que a lo largo de la historia han tenido las enseñanzas, cabe destacar que la configuración del centro docente para la formación profesional, como escenario educativo de primer orden, que llega con medio siglo de retraso respecto a las escuelas, cuenta con escasos referentes que responden a un periodo muy concreto y que, en la actualidad, persisten excesivamente contaminados debido a la continua puja por la vinculación de estas con otros niveles educativos.

Evolution induced by dry minor mergers onto fast-rotator S0 galaxies

We analysed collisionless N-body simulations of intermediate and minor dry mergers onto S0s to test whether these mergers can generate S0 galaxies with kinematics intermediate between fast and slow rotators. We find that minor mergers induce a lower decrease of the global rotational support than encounters of lower mass ratios, which results in S0s with properties intermediate between fast and slow rotators. The resulting remnants are intrinsically more triaxial, less flattened, and span the whole range of apparent ellipticities up to $\epsilon_\mathrm{e} \sim 0.8$. They do not show lower apparent ellipticities in random projections than initially; on the contrary, the formation of oval distortions and the disc thickening increase the percentage of projections at $0.4 < \epsilon_\mathrm{e} < 0.7$. In the experiments with S0b progenitor galaxies, minor mergers tend to spin up the bulge and to decrease slightly its intrinsic ellipticity, whereas in the cases of primary S0c galaxies they keep the rotational support of the bulge nearly constant and decrease significantly its intrinsic ellipticity. The remnant bulges remain nearly spherical ($B/A \sim C/A > 0.9$), but exhibit a wide range of triaxialities ($0.20 < T < 1.00$). In the plane of global anisotropy of velocities ($\delta$) vs. intrinsic ellipticity ($\epsilon_\mathrm{e,intr}$), some of our models extend the linear trend found in previous major merger simulations towards higher $\epsilon_\mathrm{e,intr}$ values, while others depart from it. This is consistent with the wide dispersion exhibited by real S0s in this diagram compared with ellipticals, which follow the linear trend drawn by major merger simulations. The different trends exhibited by ellipticals and S0 galaxies in the $\delta$ - $\epsilon_\mathrm{e}$ diagram may be pointing to the different role played by major mergers in the build-up of each morphological type.Comment: Corrected typos. 20 pages, 14 figures.

Prevalence of Depression in Retirees: A Meta-Analysis

Background: Retirement is a final life stage characterized by the ceasing of work and the loss of a routine, social relations, role, status, accomplishments, and aspirations, etc. Many times it is accompanied by negative feelings and can provoke different psychoemotional reactions such as depression, among others. The aim of this study is to analyze the prevalence of depression, as well as its psychoeducational approach in retirees. Methods: A paired systematic review with meta-analysis was conducted in different databases-Medline, Scopus, CUIDEN, CINAHL, LILACS and PsycINFO. Original studies were included in English, Spanish and French that were published in the last 10 years, and which approached depression in retirees. Results: A total of 11 articles were selected after applying inclusion and exclusion criteria. The mean value of the prevalence levels of depression in retirees obtained in the meta-analysis was 28%. Depression is more frequent in retirees, with mandatory retirement, retirement due to illness, and anticipated retirement presenting higher levels of this disease. The health role in the psychoeducational approach is highlighted in 41.6% (n = 5). Conclusions: With almost one-third of retirees suffering from depression, it is necessary to implement prevention and early detection measures to approach a public health problem

Shards: An optical spectro-photometric survey of distant galaxies

Pérez-González et al.We present the Survey for High-z Absorption Red and Dead Sources (SHARDS), an ESO/GTC Large Program carried out using the OSIRIS instrument on the 10.4 m Gran Telescopio Canarias (GTC). SHARDS is an ultra-deep optical spectro-photometric survey of the GOODS-N field covering 130 arcmin2 at wavelengths between 500 and 950 nm with 24 contiguous medium-band filters (providing a spectral resolution R ∿ 50). The data reach an AB magnitude of 26.5 (at least at a 3σ level) with sub-arcsec seeing in all bands. SHARDS' main goal is to obtain accurate physical properties of intermediate- and high-z galaxies using well-sampled optical spectral energy distributions (SEDs) with sufficient spectral resolution to measure absorption and emission features, whose analysis will provide reliable stellar population and active galactic nucleus (AGN) parameters. Among the different populations of high-z galaxies, SHARDS' principal targets are massive quiescent galaxies at z > 1, whose existence is one of the major challenges facing current hierarchical models of galaxy formation. In this paper, we outline the observational strategy and include a detailed discussion of the special reduction and calibration procedures which should be applied to the GTC/OSIRIS data. An assessment of the SHARDS data quality is also performed. We present science demonstration results on the detection and study of emission-line galaxies (star-forming objects and AGNs) at z = 0-5. We also analyze the SEDs for a sample of 27 quiescent massive galaxies with spectroscopic redshifts in the range 1.0 < z ≲ 1.4. We discuss the improvements introduced by the SHARDS data set in the analysis of their star formation history and stellar properties. We discuss the systematics arising from the use of different stellar population libraries, typical in this kind of study. Averaging the results from the different libraries, we find that the UV-to-MIR SEDs of the massive quiescent galaxies at z = 1.0-1.4 are well described by an exponentially decaying star formation history with scale Ï„ = 100-200 Myr, age around 1.5-2.0 Gyr, solar or slightly sub-solar metallicity, and moderate extinction, A(V) ∿ 0.5 mag. We also find that galaxies with masses above M* are typically older than lighter galaxies, as expected in a downsizing scenario of galaxy formation. This trend is, however, model dependent, i.e., it is significantly more evident in the results obtained with some stellar population synthesis libraries, and almost absent in others. © 2013.

Aerobic training down-regulates pentraxin 3 and pentraxin 3/toll-like receptor 4 ratio, irrespective of oxidative stress response, in elderly subjects

[EN] Reactive oxygen and nitrogen species-mediated cellular aging has been linked to diseases such as atherothrombosis and cancer. Although pentraxin 3 (PTX3) is associated with aging-related diseases via TLR4-dependent anti-inflammatory effects, its relationship with oxidative stress in aging remains to be elucidated. Exercise is proposed as the key intervention for health maintenance in the elderly. This study aimed to examine the association of PTX3 levels with changes in oxidative stress in both plasma and peripheral blood mononuclear cells (PBMCs), following aerobic training in elderly adults. Nine trained and five controls participated in an eight-week aerobic training protocol. Enzyme-linked immunosorbent assay (ELISA) and Western blot analyses were used to determine PTX3, toll-like receptor 4 (TLR4), and levels of oxidative stress biomarkers [3-nitrotyrosine (3NT), 4-hydroxynonenal (4-HNE), reduced glutathione (GSH), protein carbonyl (PC), reactive oxygen/ nitrogen species (ROS/RNS), trolox equivalent antioxidant capacity (TEAC)] in plasma and/or PBMCs. Results showed a down-regulation of PTX3 expression in PBMCs following aerobic training, along with decreased PTX3/TLR4 ratios. Oxidative stress responses in PBMCs remained unchanged with the exercise protocol. Comparable levels of plasma PTX3 and oxidative stress biomarkers were observed in trained vs. control groups. No correlation was found between PTX3 and any oxidative stress biomarkers following training. These findings demonstrated the down-regulation of PTX3 and PTX3/TLR4 ratio, irrespective of oxidative stress response, in elderly adults following eight weeks of aerobic training.SIFunding for this project was provided by the Department of Exercise Science and Health Promotion at Florida Atlantic University.

The action of obestatin in skeletal muscle repair: stem cell expansion, muscle growth, and microenvironment remodeling

The development of therapeutic strategies for skeletal muscle diseases, such as physical injuries and myopathies, depends on the knowledge of regulatory signals that control the myogenic process. The obestatin/GPR39 system operates as an autocrine signal in the regulation of skeletal myogenesis. Using a mouse model of skeletal muscle regeneration after injury and several cellular strategies, we explored the potential use of obestatin as a therapeutic agent for the treatment of trauma-induced muscle injuries. Our results evidenced that the overexpression of the preproghrelin, and thus obestatin, and GPR39 in skeletal muscle increased regeneration after muscle injury. More importantly, the intramuscular injection of obestatin significantly enhanced muscle regeneration by simulating satellite stem cell expansion as well as myofiber hypertrophy through a kinase hierarchy. Added to the myogenic action, the obestatin administration resulted in an increased expression of VEGF/VEGFR2 and the consequent microvascularization, with no effect on collagen deposition in skeletal muscle. Furthermore, the potential inhibition of myostatin during obestatin treatment might contribute to its myogenic action improving muscle growth and regeneration. Taken together, our data demonstrate successful improvement of muscle regeneration, indicating obestatin is a potential therapeutic agent for skeletal muscle injury and would benefit other myopathies related to muscle regeneration
