La creación como estrategia para construcción del conocimiento

Inside a dynamic world, the pedagogic trends must accompany these transformations, noticing the importance of the implementation of meta-cognitive activities and of integration ones, as the education across the creation and auto-management of projects. The new of this methodology is that the content to teaching is a resource to formulate problems that would stimulate the reconstruction of the ideas, the perceptions and the attitudes of the students. In this way the apprentices acquire aptitude to take part in new experiences which lead them to a process of exchange and production of meanings, whereas the teachers could integrate their own activity, by means of a transparent auto-evaluation.Dentro de un mundo dinámico, las tendencias pedagógicas deben acompañar estas transformaciones, notando la importancia de la implementación de actividades meta-cognitivas e integradoras, como la enseñanza a través de la creación y autogestión de proyectos propios. Lo novedoso de esta metodología es que el contenido a enseñar se transforma en un recurso para plantear problemas que impulsen la reconstrucción de las ideas, generen nuevas percepciones y perfilen las actitudes de los alumnos. Así los aprendices adquieren capacidad para participar y desenvolverse en experiencias nuevas, mientras que los docentes complementan su propia actividad, mediante una autoevaluación transparente que retroalimenta su actividad

Desarrollo de un plan de promoción en el sector inmobiliario

El presente documento describe el desarrollo de un plan de promoción para rentar una finca ubicada en la zona metropolitana de Guadalajara, que tiene una dificultad para rentarse debido a su perfil de construcción y ubicación. En el desarrollo del plan de promoción se acentúan las debilidades de la empresa inmobiliaria que administra este inmueble y se establecen estrategias para poder establecer conexiones con los clientes. Por otro lado, se señala la importancia de adentrarse en las redes sociales para atraer a personas que tengan interés en rentar la finca

Model-independent Study of Electric Dipole Transitions in Quarkonium

The paper contains a systematic, model-independent treatment of electric dipole (E1) transitions in heavy quarkonium. Within the effective field theory framework of potential non-relativistic QCD (pNRQCD), we derive the complete set of relativistic corrections of relative order v^2 both for weakly and strongly-coupled quarkonia. The result supports and complements former results from potential model calculations.Comment: 42 pages, 9 figure

Brightest Cluster Galaxies at the Present Epoch

We have observed 433 z<=0.08 brightest cluster galaxies (BCGs) in a full-sky survey of Abell clusters. The BCG Hubble diagram is consistent to within 2% of a Omega_m=0.3, Lambda=0.7 Hubble relation. The L_m-alpha relation for BCGs, which uses alpha, the log-slope of the BCG photometric curve of growth, to predict metric luminosity, L_m, has 0.27 mag residuals. We measure central stellar velocity dispersions, sigma, of the BCGs, finding the Faber-Jackson relation to flatten as the metric aperture grows to include an increasing fraction of the total BCG luminosity. A 3-parameter "metric plane" relation using alpha and sigma together gives the best prediction of L_m, with 0.21 mag residuals. The projected spatial offset, r_x, of BCGs from the X-ray-defined cluster center is a gamma=-2.33 power-law over 1<r_x<10^3 kpc. The median offset is ~10 kpc, but ~15% of the BCGs have r_x>100 kpc. The absolute cluster-dispersion normalized BCG peculiar velocity |Delta V_1|/sigma_c follows an exponential distribution with scale length 0.39+/-0.03. Both L_m and alpha increase with sigma_c. The alpha parameter is further moderated by both the spatial and velocity offset from the cluster center, with larger alpha correlated with the proximity of the BCG to the cluster mean velocity or potential center. At the same time, position in the cluster has little effect on L_m. The luminosity difference between the BCG and second-ranked galaxy, M2, increases as the peculiar velocity of the BCG within the cluster decreases. Further, when M2 is a close luminosity "rival" of the BCG, the galaxy that is closest to either the velocity or X-ray center of the cluster is most likely to have the larger alpha. We conclude that the inner portions of the BCGs are formed outside the cluster, but interactions in the heart of the galaxy cluster grow and extend the envelopes of the BCGs.Comment: Accepted for publication in the Astrophysical Journa

Postcard: #38 Throwing Calf to Brand

This black and white photographic postcard features the backside of a man and horse who have just lassoed a calf. Three men standing on the ground move to wrestle the calf to the ground. Several cows and a fence are in the background. Written text is at the bottom of the card. Handwriting is on the back of the card.

Tsunami Wave Analysis and Possibility of Splay Fault Rupture During the 2004 Indian Ocean Earthquake

The 2004 Indian Ocean tsunami was observed by two satellites, close in space and time, that traversed the Indian ocean two hours after the Sumatra-Andaman earthquake, but which observed different tsunami lead wave morphologies. The earlier satellite, Jason-1, recorded a lead wave with two peaks of similar amplitude and wavelength, while the later satellite, TOPEX/Poseidon, recorded a lead wave with only one longer wavelength uplift. To resolve this disparity, we examine the travel paths of long wavelength waves over the seafloor bathymetry. Waves traveling from the margin will traverse significantly different paths to arrive at the two satellite transects. The result is that the satellites are sensitive to different parts of the margin; Jason-1 is highly sensitive to the margin in the area of the epicenter, while TOPEX is sensitive to a more northerly section. By developing solutions of the ocean gravity wave equations, accounting for dispersion, we show that the double peak of the Jason-1 satellite observations are consistent with coseismic rupture of a splay fault of limited along-strike extent, located north of Simeulue Island. The doubly peaked morphology can be reproduced with co-activation of the subduction zone interface and the splay fault, which creates a seafloor uplift pattern with two distinct areas of uplift. The Jason-1 satellite is sensitive to a splay fault in this portion of the margin, whereas the TOPEX satellite would not be significantly affected by this uplift pattern. By back-projecting satellite observation points to the margin, we constrain the location of the proposed splay fault and find that it correlates with a bathymetric high. The aftershock locations, uplift of corals on Simeulue Island and a fault scarp on Pulau Salaut Besar are also consistent with the activation of a splay fault in the area delimited by the back-projection. Our work also shows that it is critical to fully capture gravity wave dispersion in order to represent features of the lead wave profile that may not be as well characterized by the shallow water (long-wavelength) model. It is also necessary to account for dispersion so as to precisely assess wavefront travel times; this leads us to conclude that the rupture must have reached very near to the trench and propagated with an updip rupture velocity of order 2.0 km/s or more.Earth and Planetary SciencesEngineering and Applied Science
