Gobierno de las universidades. Una propuesta de estudio desde la teoría de agencia

En todos los países iberoamericanos, se están discutiendo fórmulas para asegurar la calidad de las universidades. Muchos concuerdan en señalar que la gestión del gobierno universitario es uno de los factores determinantes para mejorar el quehacer administrativo y, desde ahí, las tareas académicas. El propósito de este trabajo es presentar una reflexión respecto de la posibilidad de estudiar el gobierno universitario desde la teoría de agencia. Para lograr este propósito, se procedió a revisar más de un centenar de textos y artículos publicados en revistas académicas de prestigio internacional. Como hallazgos relevantes, se pueden destacar la identificación y la reflexión en torno a elementos y factores determinantes considerados por la teoría de agencis, que son aplicables al mundo de la gestión universitaria

Kinematic Structure in the Galactic Halo at the North Galactic Pole: RR Lyrae and BHB Stars show different kinematics

Space motions are given for 38 RR Lyrae (RRL) stars and 79 blue horizontal branch (BHB) stars in a ~200 deg2 area around the North Galactic Pole (NGP) using a homogeneous distance scale consistent with (m-M)0=18.52 for the LMC. The kinematics of the 26 RRL and 52 BHB stars in the 10.4 cubic kpc volume that have Z<8 kpc are not homogeneous. Our BHB sample (like that of Sirko et al. 2004b) has a zero galactic rotation (V_phi) and roughly isotropic velocity dispersions. The RRL sample shows a definite retrograde rotation (V_phi = -95+/-29 km/s) and non-isotropic velocity dispersions. The combined BHB and RRL sample has a retrograde galactic rotation (V) that is similar to that found by Majewski (1992) for his sample of subdwarfs in SA 57. The velocity dispersion of the RRL stars that have a positive W motion is significantly smaller than the dispersion of those "streaming down" with a negative W. One component of our sample (rich in RRL's) shows retrograde rotation and the streaming motion that we associate with the accretion process. The other (traced by the BHB stars) shows essentially no rotation and less evidence of streaming. These two components have HB morphologies that suggest that they may be the field star equivalents of the young and old halo globular clusters respectively.Comment: Accepted for publication on MNRAS. 20 pages, 7 figures, 12 table

Modelar y resolver problemas con la calculadora ClassPad 330

En Portugal, los exámenes finales de matemáticas que dan acceso a la universidad vienen realizándose desde el año 1999 con calculadora gráfica. No es que se tolere el uso de calculadora gráfica en la resolución de los problemas, es que la resolución de los problemas propuestos no sería posible si no se dispone de una buena calculadora gráfica. En pocas palabras, la calculadora gráfica es obligatoria, como podemos observar en los mismos enunciados de los exámenes. Por otra parte, la calculadora gráfica está presente no solamente en los exámenes nacionales que permiten acceder a la universidad, sino también en los exámenes finales de matemáticas de 10º, y 11º año de Secundaria, en los que también su uso es obligatorio

The Cherenkov Telescope Array Large Size Telescope

The two arrays of the Very High Energy gamma-ray observatory Cherenkov Telescope Array (CTA) will include four Large Size Telescopes (LSTs) each with a 23 m diameter dish and 28 m focal distance. These telescopes will enable CTA to achieve a low-energy threshold of 20 GeV, which is critical for important studies in astrophysics, astroparticle physics and cosmology. This work presents the key specifications and performance of the current LST design in the light of the CTA scientific objectives.Comment: 4 pages, 5 figures, In Proceedings of the 33rd International Cosmic Ray Conference (ICRC2013), Rio de Janeiro (Brazil).

Seroprevalence of Antibodies against Seal Influenza A(H10N7) Virus in Harbor Seals and Gray Seals from the Netherlands

In the spring and summer 2014, an outbreak of seal influenza A(H10N7) virus infection occurred among harbor seals (Phoca vitulina) off the coasts of Sweden and Denmark. This virus subsequently spread to harbor seals off the coasts of Germany and the Netherlands. While thousands of seals were reported dead in Sweden, Denmark and Germany, only a limited number of seals were found dead in the Netherlands. To determine the extent of exposure of seals in the Netherlands to influenza A/H10N7 virus, we measured specific antibody titers in serum samples from live-captured seals and seals admitted for rehabilitation in the Netherlands by use of a hemagglutination inhibition assay and an ELISA. In harbor seals in 2015, antibodies against seal influenza A(H10N7) virus were detected in 41% (32 out of 78) pups, 10% (5 out of 52) weaners, and 58% (7 out of 12) subadults or adults. In gray seals (Halichoerus grypus) in 2015, specific antibodies were not found i
