Stated Preference Approaches for Measuring Passive Use Values: Choice Experiments and Contingent Valuation
Authors: Adamowicz Wiktor , Boxall Peter , Williams Michael , Louviere Jordan 
Published: July 2006

AbstractThe measurement of passive use values has become an important issue in environmental economics. In this paper we examine an extension or variant of contingent valuation, the choice experiment, which employs a series of questions with more than two alternatives that are designed to elicit responses that allow the estimation of preferences over attributes of an environmental state. We also combine the information from choice experiments and contingent valuation to test for differences in preferences and error variances arising from the two methods. Our results show that choice experiments have considerable merit in measuring passive use values.
Migration of Seasonal Agricultural Workers
Authors: Perloff Jeffrey M. , Lynch Lori , Gabbard Susan M. 
Published: July 2006

AbstractNearly half of all seasonal farm workers migrate at least 75 miles in a given year. An expected earnings differential from migration weakly induces migration: a 10% earnings differential raises the probability of migrating by slightly more than 1%. This result indicates that there are substantial costs to migrating and that employers must offer large earnings premia to induce a substantial number of workers to move to their jobs. Some demographic groups earn substantially higher earnings by migrating. These higher earnings from migration are primarily due to higher wages rather than more hours of work.
Chiral Scandium Catalysts for Enantioselective Michael Reactions of β‐Ketoesters
Authors: Ogawa Chikako , Kizu Keiko , Shimizu Haruka , Takeuchi Masahiko , Kobayashi Shu 
Published: July 2006

AbstractA highly enantioselective Michael reaction of β‐ketoesters with α,β‐unsaturated ketones promoted by a chiral scandium catalyst has been developed. In the presence of Sc(OTf)3 and (S,S)‐6,6′‐bis(1‐hydroxy‐2,2′‐dimethylpropyl)‐2,2′‐bipyridine, the desired Michael reactions proceeded smoothly in dichloroethane at 40 °C to afford the corresponding adducts in good to high yields with excellent enantioselectivities in most cases. It was found in this reaction that a lower concentration of the reaction mixture was key to attaining high enantioselectivities.
Transcatheter closure of coronary artery fistulae using the Amplatzer duct occluder

Published: July 2006

AbstractObjective: The aim of this study is to report our experience using the Amplatzer Duct Occluder (ADO) for occlusion of significant coronary artery fistulae (CAF). Background: Transcatheter closure of CAF with coils is well described. Use of newer devices may offer advantages such as improved control of device placement, use of a single instead of multiple devices, and high rates of occlusion. Methods: A retrospective review of all patients catheterized for CAF from July 2002 through August 2005 was performed. Results: Thirteen patients with CAF underwent cardiac catheterization, of which a total of 6 patients had ADO placement in CAF (age, 21 days to 56 years; median age, 4.3 years and weight, 3.8 kg to 74.6 kg; median weight, 13.3 kg). An arteriovenous wire loop was used to advance a long sheath antegrade to deploy the ADO in the CAF. Immediate and short‐term outcomes (follow‐up, 3 months to 14 months; median follow‐up, 8.5 months) demonstrated complete CAF occlusion in 5 patients and minimal residual shunt in 1 patient (who had resolution of right atrial and right ventricular enlargement). On follow‐up clinical evaluation, all 6 patients had absence of fistula‐related murmurs, and 2 previously symptomatic patients had resolution of congestive heart failure symptoms. Early complications included transient palpitations and atrial arrhythmia in the 2 oldest patients (52 and 56 years old). Conclusions: Use of the ADO is applicable for transcatheter closure of significant CAF. Advantages of using the ADO include the antegrade approach, use of a single device, and effective CAF occlusion. © 2006 Wiley‐Liss, Inc.

Time‐dependent density‐functional approaches to ultrafast intersubband dynamics in quantum wells
Authors: Wijewardane H. O. , Ullrich C. A. 
Published: July 2006

AbstractTime‐dependent density‐functional theory (TDDFT) has the capability to describe the dynamics of manyelectron systems in principle exactly. This article provides a brief overview of the basic concepts of TDDFT, and discusses two applications to ultrafast intersubband processes in semiconductor quantum wells.

Exciton Aharonov‐Bohm effect in quantum dot rings
Authors: Grochol M. , Grosse F. , Zimmermann R. 
Published: July 2006

AbstractThe exciton Aharonov‐Bohm effect in InP/GaAs quantum dots is investigated for different geometries. Strong confinement in the growth direction is assumed. The effects of the strain on the conduction and valence bands are included adopting an isotropic elasticity approach. It is shown that the inclusion of strain induces a ring‐like confinement for the hole but not for the electron. This is not sufficient to observe exciton Aharonov‐Bohm oscillations in these structures. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Exciton transport and intersubband transitions in Cu2O
Authors: Fleck T. , Jörger M. , Klingshirn C. 
Published: July 2006

AbstractWe present new model calculations for exciton diffusion in Cu2O, results of a quantitative comparison to experimental data and finally an attempt to understand the discrepancy of the lifetimes deduced from transport measurements and intersubband transitions. For 1s densities below 1019 cm–3 we find simple diffusive behavior (with lifetimes of at least 25 µs) but strong deviations thereof at even higher densities. (© 2006 WILEY‐VCH Verlag GmbH & Co.

Polariton entanglement in the self‐stimulated regime
Authors: Portolan S. , Di Stefano O. , Savasta S. , Rossi F. , Girlanda R. 
Published: July 2006

AbstractWe investigate the influence of environmental noise on polariton entangled pairs in the self‐stimulated regime. By adopting a recent separability criterion, we show that self‐stimulation may suppress the detrimental influence of noise on entanglement, but once effective, a noise‐equipped classical model of parametric emission provides the same results of quantum theory with respect to the separability criterion. More generally we show that, in the macroscopic limit, it is not possible to observe violations of local realism with measurements of finite order n ‐particle correlations only. These results provide a prototypical case of the emergence of macroscopic local realism in the presence of strong entanglement even in the absence of decoherence. (© 2006 WILEY‐VCH Verlag GmbH & Co.

Theory of semiconductor laser cooling at low temperatures
Authors: Rupper G. , Kwong N. H. , Binder R. 
Published: July 2006

AbstractWe present a microscopic many‐body theory of laser cooling of semiconductors. Using a standard diagrammatic Green's function approach, we calculate the absorption/luminescence spectra of a partially ionized electron‐hole plasma in quasi‐equilibrium at the self‐consistent T‐matrix level. This theory is applied to studying criteria of cooling threshold and efficiency in bulk GaAs, focusing mainly on the temperature range between 5 K and 100 K. In particular, we discuss the transition from the high temperature regime dominated by absorption in the e‐h continuum to the low temperature regime dominated by resonant exciton absorption.

Dynamical effects and terahertz harmonic generation in low‐doped bulk semiconductors and submicron structures
Authors: Persano Adorno D. , Capizzo M. C. , Zarcone M. 
Published: July 2006

AbstractWe present results obtained using a three‐dimensional multivalleys Monte Carlo (MC) model to simulate the nonlinear carrier dynamics under the influence of an intense sub‐terahertz electric field in a doped bulk semiconductor. By self‐consistently coupling a one‐dimensional Poisson solver to the ensemble MC code we simulate also the nonlinear carrier dynamics in n+nn+ structures operating under large‐amplitude periodic signals and investigate the voltage‐current characteristic hysteresis cycle and the high‐order harmonic efficiency. For both cases we discuss the dependence of the nonlinearities and of the harmonic generation efficiency on the frequency and the intensity of the alternating signal.

Nature and dynamics of carrier escape from InAs/GaAs quantum dots
Authors: Rubel O. , Dawson P. , Baranovskii S. D. , Pierz K. , Thomas P. , Göbel E. O. 
Published: July 2006

AbstractIn this paper we describe a theoretical model for the dynamics of electrons and holes in InAs/GaAs quantum dots. The key process governing the dynamics is the carrier exchange between quantum dots and the surrounding barriers. We report on two different models that differ in the nature of the carrier exchange mechanism. In the first model electrons and holes are treated as independent carriers, while in the alternative model the carriers are treated as excitons. We show that the two models predict distinctly different behavior of the thermal quenching of the photoluminescence intensity for different pump intensity. Experiments are carried out in order to verify the relevance of theoretical predictions. Comparison between the experimental data and theoretical results suggests that electrons and holes behave as independent species rather than as excitons. (© 2006 WILEY‐VCH Verlag GmbH & Co.

Outcomes After Liver Transplantation
Authors: Bucuvalas John C. , Campbell Kathleen M. , Cole Conrad R. , Guthery Stephen L. 
Published: July 2006

ABSTRACTSince the advent of transplantation as a life‐saving procedure for patients with end‐stage liver disease, more than 15,000 children and adolescents have received liver transplants. With the improvements in long‐term posttransplant survival offered by advances in medical and surgical therapy, the concept of transplantation outcome has expanded beyond simple patient and graft survival rates. The quality of the life years restored, the long‐term complications of transplant immunosuppression, and the overall cost of care have been increasingly recognized as important components of liver transplantation outcome. This review focuses on the efforts of a single pediatric transplant center to examine the incidence of, and risk factors for, common posttransplantation complications, to characterize posttransplantation health‐related quality of life, to describe the cost of posttransplant care, and to implement novel programs to improve health care delivery. Together, these projects set the future course for research and care improvement initiatives in this population and encourage us to “keep the end in mind” when considering pediatric liver transplantation.
