Aportes de Frederick W. Taylor : Dos caras de una misma moneda

La escuela de la administración científica es el punto de partida de la administración contemporánea. Uno de sus principales exponentes fue Frederick W. Taylor con su obra Principios de Administración Científica. Sus estudios comienzan en el año 1880, en un contexto político de corte totalmente autoritario; en lo social, la legislación laboral y sindical era muy escasa y en cuanto a lo económico, el desarrollo de la tecnología cambiaba la realidad de las organizaciones. Una de las críticas que los manuales de administración hacen al autor es que trató al hombre como a un engranaje más de la maquinaria. Si bien es cierto que en la obra se hace referencia a la productividad del hombre y de la máquina y que hay párrafos a través de los cuales podría inferirse esta asimilación hombre-máquina, no puede dejar de mencionarse que Taylor estudió al hombre y sus capacidades, con los recursos intelectuales de que dispuso, en ese contexto histórico y social al que se hace referencia. En ese marco el objetivo del presente trabajo es analizar y reflexionar sobre la mencionada obra de Taylor, plasmando diferentes perspectivas, intentando una crítica constructiva que promueva una mirada más amplia respecto de sus aportes

A high-resolution record of the atmospheric CO2 concentration from 60-20 kyr BP from the Taylor Dome ice core, Antarctica

A high-resolution record of the atmospheric CO2 concentration from 60 to 20 thousand years before present (kyr BP) based on measurements on the ice core of Taylor Dome, Antarctica is presented. This record shows four distinct peaks of 20 parts per million by volume (ppmv) on a millennial time scale. Good correlation of the CO2 record with temperature reconstructions based on stable isotope measurements on the Vostok ice core (Antarctica) is found.

Self-consistent numerical dispersion relation of the ablative Rayleigh-Taylor instability of double ablation fronts in inertial confinement fusion

The linear stability analysis of accelerated double ablation fronts is carried out numerically with a self-consistent approach. Accurate hydrodynamic profiles are taken into account in the theoretical model by means of a fitting parameters method using 1D simulation results. Numerical dispersión relation is compared to an analytical sharp boundary model [Yan˜ez et al., Phys. Plasmas 18, 052701 (2011)] showing an excellent agreement for the radiation dominated regime of very steep ablation fronts, and the stabilization due to smooth profiles. 2D simulations are presented to validate the numerical self-consistent theory.

1.3 John D. Taylor, Democrat, MO House of Representatives, 39th District

However, the State of Missouri was not going to go down without a fight. In mid- January, 1939, John D. Taylor, a representative from Keytesville, MO, introduced a bill in the Missouri legislature designed to postpone integration of the University. Taylor, chairman of the House Appropriations committee, proudly called himself “an unreconstructed rebel.” Taylor’s proposal, House Bill No. 195, authorized Lincoln University to “establish whatever graduate and professional schools are necessary to the equivalent of the University of Missouri.”

Ex vivo evaluation of a Taylor-Couette flow, immobilized heparinase I device for clinical application

Efficient and safe heparin anticoagulation has remained a problem for continuous renal replacement therapies and intermittent hemodialysis for patients with acute renal failure. To make heparin therapy safer for the patient with acute renal failure at high risk of bleeding, we have proposed regional heparinization of the circuit via an immobilized heparinase I filter. This study tested a device based on Taylor-Couette flow and simultaneous separation/reaction for efficacy and safety of heparin removal in a sheep model. Heparinase I was immobilized onto agarose beads via cyanogen bromide activation. The device, referred to as a vortex flow plasmapheretic reactor, consisted of two concentric cylinders, a priming volume of 45 ml, a microporous membrane for plasma separation, and an outer compartment where the immobilized heparinase I was fluidized separately from the blood cells. Manual white cell and platelet counts, hematocrit, total protein, and fibrinogen assays were performed. Heparin levels were indirectly measured via whole-blood recalcification times (WBRTs). The vortex flow plasmapheretic reactor maintained significantly higher heparin levels in the extracorporeal circuit than in the sheep (device inlet WBRTs were 1.5 times the device outlet WBRTs) with no hemolysis. The reactor treatment did not effect any physiologically significant changes in complete blood cell counts, platelets, and protein levels for up to 2 hr of operation. Furthermore, gross necropsy and histopathology did not show any significant abnormalities in the kidney, liver, heart, brain, and spleen.
