Factores psicosociales y organizacionales que afectan la productividad

Gran parte del contenido que se expone a continuación, corresponde a una selección detallada de ciertos factores psicosociales y organizacionales que sin duda interfieren en el desempeño del empleado, afectando la productividad dentro de las organizaciones. Hoy, las estructuras empresariales tienen grandes retos que cumplir debido a los cambios de mercados en los que se encuentran inmersos. La necesidad de administrar bien los recursos de las organizaciones se convierte en una realidad tangible, no obstante, existe un recurso dentro de las mismas que es imprescindible para que los demás ciclos operen, y este es llamado recurso HUMANO. Es preciso decir que no existe otro elemento más importante que el conjunto de habilidades, comportamientos y competencias con que cuenta el ser humano, que a su vez, son sus herramientas a la hora de desarrollar su trabajo, sea cual fuese su escenario. Este se convierte en un factor diferenciador y es pieza clave en cualquier proceso de cambio, como en el aumento de la productividad y competitividad de las organizaciones. Por esta razón, y teniendo en cuenta la influencia de sus recursos en su ejercicio diario, es importante que las organizaciones asuman y piensen que deben tomar un canal para lograrlo, en el que los ejes fundamentales apunten al mantenimiento de óptimos niveles de bienestar de la salud; el desafío es promover estructuras con espacios saludables que generen bienestar y calidad de vida laboral, y desde esta perspectiva, se muestra como pueden ser intervenidos estos factores.Most of this text is about a detailed selection of some psychosociological and organizational factors which no doubt afect the performance of the employee and the productivity within the organizations. Today, organizational structures have great challenges to acomplish because of the markets in which they are. The need to manage well organization resources becomes a true need, nevertheless, there is a resource inside them for the other cycles to work, this is the Human Resource. There is no other element more important for the set of skills, behaviors and competences of the human being that is also their tools at the time to develop their work, no matter the scenario. This is why, considering the influence of resources in everyday activities, it is important for the organizations to face and think that they have to take a chanel to succed, in which the core ideas point to keep the optimal levels of welfare and health. The callenge is to promote strucrues with healty spaces to generate welfare and work life quality, and in this point of view we can see how to intervene these factors

Efeito conjunto da democracia e da liberdade econômica sobre a corrupção

This work examines the joint effect of democracy and economic freedom on corruption. The study used a database of 160 countries from 2010 - 2016, containing information for a set of economic, cultural, historical, and institutional variables. Several researches show that the joint effect of economic freedom levels and democracy are essential to fight corruption. Therefore, the most effective public policies for countries under study are those focused on the fundamental right of human beings to control satisfying outcomes of their jobs, which holistically encompasses the freedom and rights of production, distribution, or consumption of goods and services

XVI International Congress of Control Electronics and Telecommunications: "Techno-scientific considerations for a post-pandemic world intensive in knowledge, innovation and sustainable local development"

Este título, sugestivo por los impactos durante la situación de la Covid 19 en el mundo, y que en Colombia lastimosamente han sido muy críticos, permiten asumir la obligada superación de tensiones sociales, políticas, y económicas; pero sobre todo científicas y tecnológicas. Inicialmente, esto supone la existencia de una capacidad de la sociedad colombiana por recuperar su estado inicial después de que haya cesado la perturbación a la que fue sometida por la catastrófica pandemia, y superar ese anterior estado de cosas ya que se encontraban -y aún se encuentran- muchos problemas locales mal resueltos, medianamente resueltos, y muchos sin resolver: es decir, habrá que rediseñar y fortalecer una probada resiliencia social existente - producto del prolongado conflicto social colombiano superado parcialmente por un proceso de paz exitoso - desde la tecnociencia local; como lo indicaba Markus Brunnermeier - economista alemán y catedrático de economía de la Universidad de Princeton- en su libro The Resilient Society…La cuestión no es preveerlo todo sino poder reaccionar…aprender a recuperarse rápido.This title, suggestive of the impacts during the Covid 19 situation in the world, and which have unfortunately been very critical in Colombia, allows us to assume the obligatory overcoming of social, political, and economic tensions; but above all scientific and technological. Initially, this supposes the existence of a capacity of Colombian society to recover its initial state after the disturbance to which it was subjected by the catastrophic pandemic has ceased, and to overcome that previous state of affairs since it was found -and still is find - many local problems poorly resolved, moderately resolved, and many unresolved: that is, an existing social resilience test will have to be redesigned and strengthened - product of the prolonged Colombian social conflict partially overcome by a successful peace process - from local technoscience; As Markus Brunnermeier - German economist and professor of economics at Princeton University - indicates in his book The Resilient Society...The question is not to foresee everything but to be able to react...learn to recover quickly.Bogot

Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| < 0.03 at 95% confidence level.

Measurement of b jet shapes in proton-proton collisions at root s=5.02 TeV

We present the first study of charged-hadron production associated with jets originating from b quarks in proton-proton collisions at a center-of-mass energy of 5.02 TeV. The data sample used in this study was collected with the CMS detector at the CERN LHC and corresponds to an integrated luminosity of 27.4 pb(-1). To characterize the jet substructure, the differential jet shapes, defined as the normalized transverse momentum distribution of charged hadrons as a function of angular distance from the jet axis, are measured for b jets. In addition to the jet shapes, the per-jet yields of charged particles associated with b jets are also quantified, again as a function of the angular distance with respect to the jet axis. Extracted jet shape and particle yield distributions for b jets are compared with results for inclusive jets, as well as with the predictions from the pythia and herwig++ event generators.Peer reviewe

Measurement of the azimuthal anisotropy of Y(1S) and Y(2S) mesons in PbPb collisions at root s(NN)=5.02 TeV

The second-order Fourier coefficients (v(2)) characterizing the azimuthal distributions of Y(1S) and Y(2S) mesons produced in PbPb collisions at root s(NN) = 5.02 TeV are studied. The Y mesons are reconstructed in their dimuon decay channel, as measured by the CMS detector. The collected data set corresponds to an integrated luminosity of 1.7 nb(-1). The scalar product method is used to extract the v2 coefficients of the azimuthal distributions. Results are reported for the rapidity range vertical bar y vertical bar < 2.4, in the transverse momentum interval 0 < pT < 50 GeV/c, and in three centrality ranges of 10-30%, 30-50% and 50-90%. In contrast to the J/psi mesons, the measured v(2) values for the Y mesons are found to be consistent with zero. (C) 2021 The Author(s). Published by Elsevier B.V.Peer reviewe
