    Nowadays the Higher Education Institutions face major challenges in its development. Demanding from different actors and the orientation of the research, more oriented to innovation and value creation, request news capacities to answer to that. Southeast Asia shows a strong economic growth with a large increase in GDP and a growing improvement in the position of The Human Development Index promoted by United Nations. This reality creates a different pressure on the higher education institutions in southeast Asia that requires a change in the universities, in the way they implement the mission and in the requested capacities, specially the human resources capacities. In this way, a new paradigm and model of human resources management for southeast higher education institutions need be developed to create the conditions to answer to this new reality, where the main analysis variables will be talent, performance, motivation and retention, coaching, cross cultural, integrity and permanent adaptability and flexibility. The main objective of this communication is to reflect and contextualize in terms of theoretical models where we find the assumptions for the implementation of strategic human resources management for southeast Asian universities. What kind of profile is request for the staff in this new reality? What we need to change in human resources management? How can this change be implemented? What HRM tools are most relevant to this reality? These are the main issues on which we will reflect with a critical thinking approach in order to present a set of clues to southeast Asian universities according to our analysis and interpretation, as Portuguese and European

    Particle velocity controls phase transitions in contagion dynamics

    Interactions often require the proximity between particles. The movement of particles, thus, drives the change of the neighbors which are located in their proximity, leading to a sequence of interactions. In pathogenic contagion, infections occur through proximal interactions, but at the same time the movement facilitates the co-location of different strains. We analyze how the particle velocity impacts on the phase transitions on the contagion process of both a single infection and two cooperative infections. First, we identify an optimal velocity (close to half of the interaction range normalized by the recovery time) associated with the largest epidemic threshold, such that decreasing the velocity below the optimal value leads to larger outbreaks. Second, in the cooperative case, the system displays a continuous transition for low velocities, which becomes discontinuous for velocities of the order of three times the optimal velocity. Finally, we describe these characteristic regimes and explain the mechanisms driving the dynamics.Comment: 9 pages, 5 figures, 12 supplementary figure

    Overview of progress in neutrino scattering measurements

    Full text link
    Recent progress in neutrino scattering experiments with few GeV neutrino beams is reviewed, focusing on new experimental input since the beginning of the NuInt workshop series in 2001. Progress in neutrino quasi-elastic scattering, resonance production, coherent pion production, scattering in the transition region between the resonance and deep inelastic regimes, and nuclear effects in neutrino-nucleus scattering, is discussed.Comment: To appear in the proceedings of 5th International Workshop on Neutrino-Nucleus Interactions in the Few-GeV Region (NuInt07), Batavia, Illinois, 30 May - 3 Jun 2007.

    Consistent discretization and loop quantum geometry

    Get PDF
    We apply the ``consistent discretization'' approach to general relativity leaving the spatial slices continuous. The resulting theory is free of the diffeomorphism and Hamiltonian constraints, but one can impose the diffeomorphism constraint to reduce its space of solutions and the constraint is preserved exactly under the discrete evolution. One ends up with a theory that has as physical space what is usually considered the kinematical space of loop quantum geometry, given by diffeomorphism invariant spin networks endowed with appropriate rigorously defined diffeomorphism invariant measures and inner products. The dynamics can be implemented as a unitary transformation and the problem of time explicitly solved or at least reduced to as a numerical problem. We exhibit the technique explicitly in 2+1 dimensional gravity.Comment: 4 pages, Revtex, no figure

    Convergence of the Crank-Nicolson-Galerkin finite element method for a class of nonlocal parabolic systems with moving boundaries

    Get PDF
    The aim of this paper is to establish the convergence and error bounds to the fully discrete solution for a class of nonlinear systems of reaction-diffusion nonlocal type with moving boundaries, using a linearized Crank-Nicolson-Galerkin finite element method with polynomial approximations of any degree. A coordinate transformation which fixes the boundaries is used. Some numerical tests to compare our Matlab code with some existing moving finite elements methods are investigated

    Understanding the Forward Muon Deficit in Coherent Pion Production

    Full text link
    For any inelastic process vℓ+I→ℓ−+Fv_{\ell} + I \to \ell^- + F with mℓ=0m_{\ell} = 0, the cross section at θℓ=0\theta_{\ell} = 0 is given by Adler's PCAC theorem. Inclusion of the lepton mass has a dynamical effect (``PCAC-screening'') caused by interference of spin-zero (π+\pi^+) and spin-one exchanges. This effect may be relevant to the forward suppression reported in recent experiments.Comment: 3 pages, 2 figures, presented at NuInt07, Fermilab, may 31 - june 3 200

    Reappraising the Spite Lithium Plateau: Extremely Thin and Marginally Consistent with WMAP

    Full text link
    The lithium abundance in 62 halo dwarfs is determined from accurate equivalent widths reported in the literature and an improved infrared flux method (IRFM) temperature scale. The Li abundance of 41 plateau stars (those with Teff > 6000 K) is found to be independent of temperature and metallicity, with a star-to-star scatter of only 0.06 dex over a broad range of temperatures (6000 K < Teff < 6800 K) and metallicities (-3.4 < [Fe/H] < -1), thus imposing stringent constraints on depletion by mixing and production by Galactic chemical evolution. We find a mean Li plateau abundance of A(Li) = 2.37 dex (7Li/H = 2.34 X 10^{-10}), which, considering errors of the order of 0.1 dex in the absolute abundance scale, is just in borderline agreement with the constraints imposed by the theory of primordial nucleosynthesis and WMAP data (2.51 < A(Li)[WMAP] < 2.66 dex).Comment: ApJ Letters, in pres
