Radiometric 81Kr dating identifies 120,000-year-old ice at Taylor Glacier, Antarctica

We present successful 81 Kr-Kr radiometric dating of ancient polarice. Krypton was extracted from the air bubbles in four∼350-kg polar ice samples from Taylor Glacier in the McMurdo Dry Valleys, Antarctica, and dated using Atom Trap Trace Analysis (ATTA). The 81 Kr radiometric ages agree with independent age estimates obtained from stratigraphic dating techniques with a mean abso-lute age offset of 6±2.5 ka. Our experimental methods and sampling strategy are validated by (i) 85 Kr and 39 Ar analyses that show the samples to be free of modern air contamination and (ii)air content measurements that show the ice did not experience gas loss. We estimate the error in the 81 Kr ages due to past geomagnetic variability to be below 3 ka. We show that ice from the previous interglacial period (Marine Isotope Stage 5e, 130–115 ka before present) can be found in abundance near the surface of Taylor Glacier. Our study paves the way for reliable radiometric dating of ancient ice in blue ice areas and margin sites where large samples are available, greatly enhancing their scientific value as archives of old ice and meteorites. At present, ATTA 81Kr analysis requires a 40–80-kg ice sample; as sample requirements continue to decrease, 81 Kr dating of ice cores is a future possibility.

Working with A Secular Age. Interdisciplinary Perspectives on Charles Taylor's Master Narrative

Charles Taylor’s monumental book A Secular Age has been extensively discussed, criticized, and worked on. This volume, by contrast, explores ways of working with Taylor’s book, especially its potentials and limits for individual research projects. Due to its wide reception, it has initiated a truly interdisciplinary object of study; with essays drawn from various research fields, this volume fosters substantial conversation across disciplines.

Impact of Taylor-Aris diffusivity on analyte and system zone dispersion in CZE assessed by computer simulation and experimental validation.

Application of pressure-driven laminar flow has an impact on zone and boundary dispersion in open tubular CE. The GENTRANS dynamic simulator for electrophoresis was extended with Taylor-Aris diffusivity which accounts for dispersion due to the parabolic flow profile associated with pressure-driven flow. Effective diffusivity of analyte and system zones as functions of the capillary diameter and the amount of flow in comparison to molecular diffusion alone were studied for configurations with concomitant action of imposed hydrodynamic flow and electroosmosis. For selected examples under realistic experimental conditions, simulation data are compared with those monitored experimentally using modular CE setups featuring both capacitively coupled contactless conductivity and UV absorbance detection along a 50 μm id fused-silica capillary of 90 cm total length. The data presented indicate that inclusion of flow profile based Taylor-Aris diffusivity provides realistic simulation data for analyte and system peaks, particularly those monitored in CE with conductivity detection.

Does the Federal Reserve Follow a Non-Linear Taylor Rule?

The Taylor rule has become one of the most studied strategies for monetary policy. Yet, little is known whether the Federal Reserve follows a non-linear Taylor rule. This paper employs the smooth transition regression model and asks the question: does the Federal Reserve change its policy-rule according to the level of inflation and/or the output gap? I find that the Federal Reserve does follow a non-linear Taylor rule and, more importantly, that the Federal Reserve followed a non-linear Taylor rule during the golden era of monetary policy, 1985-2005, and a linear Taylor rule throughout the dark age of monetary policy, 1960-1979. Thus, good monetary policy is associated with a non-linear Taylor rule: once inflation approaches a certain threshold, the Federal Reserve adjusts its policy-rule and begins to respond more forcefully to inflation.

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
