The absorption of a resonant coupling laser driving a closed degenerate two-level system in an atomic cesium beam was investigated as a function of the detuning of a second laser probing the same transition. The measurements were performed for four different polarization combinations of the two laser beams. Except for the beams of counterrotating polarizations all coupling-laser absorption prof...
We consider whether a career-minded expert would make better decisions if the principal could observe the consequences of the expert’s action. The previous literature has found that this “transparency of consequence” can only improve the efficacy of the expert’s decision making. We show, however, that this conclusion is very sensitive to the specified cost structure. While learning the conseque...
We use unique panel data on the evolution of transparent budget procedures in the American states over the past three decades to explore the political and economic determinants of fiscal transparency. Our preliminary results suggest that more equal political competition and power sharing are associated with both greater levels of fiscal transparency and increases in fiscal transparency during t...
In this paper, electromagnetically induced transparency (EIT) in a system consisting of associated arrays of parallel slabs (metal-dielectric-metal) is studied. The transmission coefficient, the reflection coefficient and the absorption coefficient as function of the incident light frequency by using the transfer matrix method is calculated and numerically discussed. Influence of the thickness ...
The global energy system is undergoing a major transition, and in energy planning and decision-making across governments, industry and academia, models play a crucial role. Because of their policy relevance and contested nature, the transparency and open availability of energy models and data are of particular importance. Here we provide a practical how-to guide based on the collective experien...
Equilibrium phase relationships in the ZnO–In2O3 system were determined between 1100° and 1400°C using solidstate reaction techniques and X-ray diffractometry. In addition to ZnO and In2O3, nine homologous compounds, ZnkIn2Ok+3 (where k = 3, 4, 5, 6, 7, 9, 11, 13, and 15), were observed. Electrical conductivity and diffuse reflectance of the k = 3, 4, 5, 7 and 11 members were measured before an...
The aims of this study are to examine how liquidity in the Government of Canada securities market has evolved over the 1990s and to determine what factors influence the level of liquidity in this market, with some comparisons to the U.S. Treasury securities market. We find empirical support for the hypothesis that an increase in effective supply of the securities enhances market liquidity. Empi...
Abstract Dialetical Frameworks (ADFs) are a recent development in computational argumentation which are, it has been suggested, a fruitful way of implementing factor based reasoning with legal cases. In this paper we evaluate this proposal, by reconstructing CATO using ADFs. We evaluate the ease of implementation, the efficacy of the resulting program, ease of refinement of the program, transpa...
We investigate the role of non-uniform spatial density profiles of trapped atomic Bose-Einstein condensates in the propagation of Raman-matched laser pulses under conditions for electromagnetically induced transparency (EIT). We find that the sharp edged axial density profile of an interacting condensate (due to a balance between external trap and repulsive atomic interaction) is advantageous f...
