Visions of Global Electronic Mastery

Este texto es una de las últimas aportaciones del pionero de la Economía Política de la Comunicación Herbert I. Schiller. El él mantiene una de sus líneas de investigación fundamentales: la extensión de la doctrina del libre flujo de la información como parte de la política exterior estadounidense. Sólo que en este caso se aplica al comercio electrónico y la era digital. En este sentido uno de lo documentos analizados en profundidad por el autor, The Framework for Global Electronic Comerce, representa la actualización de la doctrina. De esta manera el mantenimiento de la hegemonía de Estados Unidos y su supremacía electrónica global serán posibles a lo largo del siglo XXI.This text is one of the last contributions of pioneer of Political Economy of Communication Herbert I. Schiller. The author keeps up with one of his fundamental thesis, that is, the extension of the free flow of information doctrine as part of the US foreign policy. In this case it is applied to electronic commerce and the digital era. In this sense one of the documents analysed in depth by the author, The Framework for Electronic Commerce, represents the actualization of this doctrine. Thus the preservation of US hegemony and its global electronic mastery will be a fact along the 21st century

Highly resolved observations of trace gases in the lowermost stratosphere and upper troposphere from the Spurt project: an overview

During SPURT (Spurenstofftransport in der Tropopausenregion, trace gas transport in the tropopause region) we performed measurements of a wide range of trace gases with different lifetimes and sink/source characteristics in the northern hemispheric upper troposphere (UT) and lowermost stratosphere (LMS). A large number of in-situ instruments were deployed on board a Learjet 35A, flying at altitudes up to 13.7 km, at times reaching to nearly 380 K potential temperature. Eight measurement campaigns (consisting of a total of 36 flights), distributed over all seasons and typically covering latitudes between 35° N and 75° N in the European longitude sector (10° W–20° E), were performed. Here we present an overview of the project, describing the instrumentation, the encountered meteorological situations during the campaigns and the data set available from SPURT. Measurements were obtained for N2O, CH4, CO, CO2, CFC12, H2, SF6, NO, NOy, O3 and H2O. We illustrate the strength of this new data set by showing mean distributions of the mixing ratios of selected trace gases, using a potential temperature – equivalent latitude coordinate system. The observations reveal that the LMS is most stratospheric in character during spring, with the highest mixing ratios of O3 and NOy and the lowest mixing ratios of N2O and SF6. The lowest mixing ratios of NOy and O3 are observed during autumn, together with the highest mixing ratios of N2O and SF6 indicating a strong tropospheric influence. For H2O, however, the maximum concentrations in the LMS are found during summer, suggesting unique (temperature- and convection-controlled) conditions for this molecule during transport across the tropopause. The SPURT data set is presently the most accurate and complete data set for many trace species in the LMS, and its main value is the simultaneous measurement of a suite of trace gases having different lifetimes and physical-chemical histories. It is thus very well suited for studies of atmospheric transport, for model validation, and for investigations of seasonal changes in the UT/LMS, as demonstrated in accompanying and elsewhere published studies

Nonlinear adiabatic response of interacting quantum dots

We develop a generic method in Liouville space to describe the dissipative dynamics of coherent interacting quantum dots with adiabatic time dependence beyond linear response. We show how the adiabatic response can be related to effective quantities known from real-time renormalization group methods for stationary quantities. We propose the study of a generalized $RC$-time as a characteristic time scale. We apply the method to the interacting resonant level model and calculate the nonlinear adiabatic charge response to time-dependent gate voltages, tunneling barriers and Coulomb interaction. The generalized $RC$-time is found to acquire a unique form in all cases, in contrast to the capacitance and the charge relaxation resistance. We discuss the observability of the effects in molecular systems and cold atom setups.Comment: 6 page
