EL ASEGURAMIENTO DE LA CALIDAD COMO POLÍTICA PÚBLICA PARA LA EDUCACIÓN SUPERIOR

La educación superior tiene efectos, resultados e impactos de diversa índole, constituyendo un instrumento para el desarrollo del capital humano de un país, la generación de conocimiento y el bienestar ciudadano. Su importancia creciente ha despertado la preocupación por su calidad, considerando los cambios ocurridos en el escenario de educación superior, el tipo de estudiante que a ella llega, la ampliación de la cobertura y la oferta académica, de calidad diversa, la falta de sistemas de información pública confiables, la mercantilización de la formación, además de la enorme relevancia que la producción del conocimiento tiene para el desarrollo de las naciones. Este contexto ha contribuido a la implementación de políticas de calidad, incluyendo desde instrumentos legales a incentivos financieros y no financieros. La percepción desde cada actor del sistema instituciones-Estado-mercado es diferente, y si bien resulta positivo en suma, existen efectos no deseables. En este estudio se analizan los procesos de aseguramiento de la calidad como política pública para la mejora de la calidad de la formación. El cambio en el rol del Estado, los organismos generados para la implementación de las políticas y sus desafíos son parte de una política pública que ha llegado para instalarse definitivamente

Structure of krypton isotopes within the interacting boson model derived from the Gogny energy density functional

The evolution and coexistence of the nuclear shapes as well as the corresponding low-lying collective states and electromagnetic transition rates are investigated along the Krypton isotopic chain within the framework of the interacting boson model (IBM). The IBM Hamiltonian is determined through mean-field calculations based on the several parametrizations of the Gogny energy density functional and the relativistic mean-field Lagrangian. The mean-field energy surfaces, as functions of the axial $\beta$ and triaxial $\gamma$ quadrupole deformations, are mapped onto the expectation value of the interacting-boson Hamiltonian that explicitly includes the particle-hole excitations. The resulting boson Hamiltonian is then used to compute low-energy excitation spectra as well as E2 and E0 transition probabilities for $^{70-100}$Kr. Our results point to a number of examples of the prolate-oblate shape transitions and coexistence both on the neutron-deficient and neutron-rich sides. A reasonable agreement with the available experimental data is obtained for the considered nuclear properties.Comment: 13 pages, 9 figures, 2 table

Intermittency at critical transitions and aging dynamics at edge of chaos

We recall that, at both the intermittency transitions and at the Feigenbaum attractor in unimodal maps of non-linearity of order $\zeta >1$, the dynamics rigorously obeys the Tsallis statistics. We account for the $q$-indices and the generalized Lyapunov coefficients $\lambda_{q}$ that characterize the universality classes of the pitchfork and tangent bifurcations. We identify the Mori singularities in the Lyapunov spectrum at the edge of chaos with the appearance of a special value for the entropic index $q$. The physical area of the Tsallis statistics is further probed by considering the dynamics near criticality and glass formation in thermal systems. In both cases a close connection is made with states in unimodal maps with vanishing Lyapunov coefficients.Comment: Proceedings of: STATPHYS 2004 - 22nd IUPAP International Conference on Statistical Physics, National Science Seminar Complex, Indian Institute of Science, Bangalore, 4-9 July 2004.

UNIVERSIDAD PARA ARMAR. LOS DESAFÍOS DE UNA UNIVERSIDAD EMPRENDEDORA

El desarrollo de un país con potencial de crecimiento es posible considerando como instrumento la gestión del conocimiento. En este marco, se plantea una Universidadque se relaciona y trabaja con la Comunidad, la Empresa y las Instituciones a las cuales ofrece sus servicios, educando al mismo tiempo. A través de dicha instancia se diseñan diversos modos de participación en el desarrollo, los que aparecen como respuesta a las necesidades de la comunidad y permiten la actuación de la Universidad en el medio social de una manera más comprometida y más ágil y en un entorno “versátil e inespacial”. La acción de dicha instancia está conformada por el diseño y gestión de los proyectos de desarrollo e innovación, las opciones de formación continua, con certificación de saberes y programas de capacitación específicos, que involucran a los profesores, investigadores, alumnos, formadores y consultores externos, contribuyendo a fortalecer el compromiso de la comunidad académica con la comunidad social. Así, el conocimiento es producido en el contexto dela aplicación, en una organización reticular, que se valida por su aplicación no solo en el contexto original, sino en los contextos sucesivos. Además, plantea la responsabilidad y la reflexión social ante los riesgos de aplicación de los descubrimientos científicos y es flexible y dinámico

Renormalization group structure for sums of variables generated by incipiently chaotic maps

We look at the limit distributions of sums of deterministic chaotic variables in unimodal maps and find a remarkable renormalization group (RG) structure associated to the operation of increment of summands and rescaling. In this structure - where the only relevant variable is the difference in control parameter from its value at the transition to chaos - the trivial fixed point is the Gaussian distribution and a novel nontrivial fixed point is a multifractal distribution that emulates the Feigenbaum attractor, and is universal in the sense of the latter. The crossover between the two fixed points is explained and the flow toward the trivial fixed point is seen to be comparable to the chaotic band merging sequence. We discuss the nature of the Central Limit Theorem for deterministic variables.Comment: 14 pages, 5 figures, to appear in Journal of Statistical Mechanic

Stationary distributions of sums of marginally chaotic variables as renormalization group fixed points

We determine the limit distributions of sums of deterministic chaotic variables in unimodal maps assisted by a novel renormalization group (RG) framework associated to the operation of increment of summands and rescaling. In this framework the difference in control parameter from its value at the transition to chaos is the only relevant variable, the trivial fixed point is the Gaussian distribution and a nontrivial fixed point is a multifractal distribution with features similar to those of the Feigenbaum attractor. The crossover between the two fixed points is discussed and the flow toward the trivial fixed point is seen to consist of a sequence of chaotic band mergers.Comment: 7 pages, 2 figures, to appear in Journal of Physics: Conf.Series (IOP, 2010

Fundamental measure theory for lattice fluids with hard core interactions

We present the extension of Rosenfeld's fundamental measure theory to lattice models by constructing a density functional for d-dimensional mixtures of parallel hard hypercubes on a simple hypercubic lattice. The one-dimensional case is exactly solvable and two cases must be distinguished: all the species with the same lebgth parity (additive mixture), and arbitrary length parity (nonadditive mixture). At the best of our knowledge, this is the first time that the latter case is considered. Based on the one-dimensional exact functional form, we propose the extension to higher dimensions by generalizing the zero-dimensional cavities method to lattice models. This assures the functional to have correct dimensional crossovers to any lower dimension, including the exact zero-dimensional limit. Some applications of the functional to particular systems are also shown.Comment: 22 pages, 7 figures, needs IOPP LaTeX styles file

Approximate particle number projection for finite range density dependent forces

The Lipkin-Nogami method is generalized to deal with finite range density dependent forces. New expressions are derived and realistic calculations with the Gogny force are performed for the nuclei $^{164}$Er and $^{168}$Er. The sharp phase transition predicted by the mean field approximation is washed out by the Lipkin-Nogami approach; a much better agreement with the experimental data is reached with the new approach than with the Hartree-Fock_Bogoliubov one, specially at high spins.Comment: 5 pages, RevTeX 3.0, 3 postscript figures included using uufiles.
