    Description: Propósito – Los call centers generan estrés y ausentismo en el personal y la literatura sugiere que el liderazgo orientado a la gente es el tipo adecuado de supervisión para tal situación. Este estudio comparó sus efectos versus los de otros tipos de liderazgo. Metodología – Datos de ausentismo de 379 representantes de servicios al cliente de un call center peruano fueron analizados y los representantes respondieron a un cuestionario sobre el Marco de Valores en Competencia y sus cuatro tipos de liderazgo. Turnos diurnos y nocturnos de trabajo fueron comparados. Resultados – Se observó que el ausentismo declina con el liderazgo orientado a la gente, aunque solo en el turno diurno, y la adición de liderazgos orientados al cambio, los resultados y el control resta validez a los modelos. Limitaciones/implicancias – Futuros estudios deberán abarcar el desempeño del trabajador. Los hallazgos sugieren una necesidad de volver a poner el foco teórico en las contingencias ambientales que afectan la eficacia del liderazgo. Originalidad/valor – Teóricos del liderazgo se preguntarán en qué circunstancias es efectivo el liderazgo múltiple. Gerentes de call centers apreciarán el valor organizacional del liderazgo orientado a la gente en el primer nivel de supervisión.

    Description: Entropy, Vol. 20, Pages 705: Spatial Organization of Five-Fold Morphology as a Source of Geometrical Constraint in Biology Entropy doi: 10.3390/e20090705 Authors: Juan López-Sauceda Jorge López-Ortega Gerardo Abel Laguna Sánchez Jacobo Sandoval Gutiérrez Ana Paola Rojas Meza José Luis Aragón A basic pattern in the body plan architecture of many animals, plants and some molecular and cellular systems is five-part units. This pattern has been understood as a result of genetic blueprints in development and as a widely conserved evolutionary character. Despite some efforts, a definitive explanation of the abundance of pentagonal symmetry at so many levels of complexity is still missing. Based on both, a computational platform and a statistical spatial organization argument, we show that five-fold morphology is substantially different from other abundant symmetries like three-fold, four-fold and six-fold symmetries in terms of spatial interacting elements. We develop a measuring system to determine levels of spatial organization in 2D polygons (homogeneous or heterogeneous partition of defined areas) based on principles of regularity in a morphospace. We found that spatial organization of five-fold symmetry is statistically higher than all other symmetries studied here (3 to 10-fold symmetries) in terms of spatial homogeneity. The significance of our findings is based on the statistical constancy of geometrical constraints derived from spatial organization of shapes, beyond the material or complexity level of the many different systems where pentagonal symmetry occurs.

    Description: Bayesian statistical inference under unknown or hard to asses likelihood functions is a very challenging task. Currently, approximate Bayesian computation (ABC) techniques have emerged as a widely used set of likelihood-free methods. A vast number of ABC-based approaches have appeared in the literature; however, they all share a hard dependence on free parameters selection, demanding expensive tuning procedures. In this paper, we introduce an automatic kernel learning-based ABC approach, termed AKL-ABC, to automatically compute posterior estimations from a weighting-based inference. To reach this goal, we propose a kernel learning stage to code similarities between simulation and parameter spaces using a centered kernel alignment (CKA) that is automated via an Information theoretic learning approach. Besides, a local neighborhood selection (LNS) algorithm is used to highlight local dependencies over simulations relying on graph theory. Attained results on synthetic and real-world datasets show our approach is a quite competitive method compared to other non-automatic state-of-the-art ABC techniques.
