El liderazgo docente
Ponencia SITEParece que la comunidad científica ha producido una cantidad notable de
evidencias para persuadirnos de que el liderazgo en los centros educativos es
importante. Además, esto se produce en un contexto donde cada vez existe una mayor
presión para el rendimiento social de cuentas. La mezcla de liderazgo y responsabilidad
al mismo tiempo ha generado nuevos contextos de trabajo en el ámbito de la educación,
como está sucediendo en otros, distintos a los que la mayoría de los profesores y
profesionales de la educación en general habíamos vivido. Comprender estas
implicaciones se ha convertido prácticamente en un asunto de supervivencia para los
docentes.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech
D=10 dyonic black holes in string inspired models
We consider string-inspired models in D=10 spacetime dimensions, which include couplings with 1- and 3-form fields as well as R4 higher-curvature corrections to the gravitational action. For such models, we explicitly construct a family of black hole solutions with both electric and magnetic charges, and with different horizon topologies. The solutions exhibit some features similar to those of self-gravitating monopoles in Einstein-Yang-Mills theory, which we discuss. When higher-curvature corrections are switched off, our solutions reduce to charged p-brane solutions previously studied in the literature. Novel qualitative features appear due to the R4 terms, though. Such is the case for the emergence of branch singularities for charged solutions that, nonetheless, can be shielded by the event horizon.Fil: Giribet, Gaston Enrique.

The effect of radial migration on galactic disks
We study the radial migration of stars driven by recurring multi-arm spiral
features in an exponential disk embedded in a dark matter halo. The spiral
perturbations redistribute angular momentum within the disk and lead to
substantial radial displacements of individual stars, in a manner that largely
preserves the circularity of their orbits and that results, after 5 Gyr (~40
full rotations at the disk scalelength), in little radial heating and no
appreciable changes to the vertical or radial structure of the disk. Our
results clarify a number of issues related to the spatial distribution and
kinematics of migrators. In particular, we find that migrators are a heavily
biased subset of stars with preferentially low vertical velocity dispersions.
This "provenance bias" for migrators is not surprising in hindsight, for stars
with small vertical excursions spend more time near the disk plane and thus
respond more readily to non-axisymmetric perturbations. We also find that the
vertical velocity dispersion of outward migrators always decreases, whereas the
opposite holds for inward migrators. To first order, newly arrived migrators
simply replace stars that have migrated off to other radii, thus inheriting the
vertical bias of the latter. Extreme migrators might therefore be recognized,
if present, by the unexpectedly small amplitude of their vertical excursions.
Our results show that migration, understood as changes in angular momentum that
preserve circularity, can affect strongly the thin disk, but cast doubts on
models that envision the Galactic thick disk as a relic of radial migration.Comment: 10 pages, 12 figures. ApJ in pres
El practicum como espacio de formación. Algunas experiencias de mejora en los grados de Infantil y Primaria.
Esta adenda, pretende contribuir a pensar la relación teoría-práctica desde uno de sus posibles ángulos de abordaje: el de la manera de diseñar el practicum como espacio curricular al servicio de una práctica reflexiva y transformadora. Para ello se presentan dos experiencias llevadas a cabo en la Facultad de Ciencias de la Educación de la Universidad de Málaga.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech
