In this paper the author continues his investigation into the scaling limit of a partial difference equation on the d-dimensional integer lattice Zd, corresponding to a translation invariant random walk perturbed by a random vector field. In a previous paper he obtained a formula for the effective diffusion constant. It is shown here that for the nearest neighbor walk in dimension d ≥ 3 this ef...

People are impatient and discount future rewards more when they are asked to delay consumption than when they are offered the chance to accelerate consumption. The three experiments reported here provide a process-level account for this asymmetry, with implications for designing decision environments that promote less impulsivity. In Experiment 1, a thought-listing procedure showed that people ...

and managers at the retailer organization for their support and assistance at different stages of this project. We also thank George John and Akbar Zaheer for insightful comments on earlier versions of the paper. Further, the comments of the Guest Editor – Rita McGrath and three anonymous AMJ reviewers were extremely useful in developing the ideas presented here. Abstract We model the governanc...

In this paper, natural frequencies and dynamic response of thick beams made of saturated porous materials resting on viscoelastic foundation are investigated for the first time. The beam is modeled using higher-order beam theory. Kelvin-voight model is used to model the viscoelastic foundation. Distribution of porosity along the thickness is considered in two different patterns, which are symme...

noses by using the equivalent axisymmetric body (EAB) theory. This Code has been developed by researchers and the results of it have been validated by the various flight tests results. In the case of non-zero angle of attack or asymmetric surface ablation for each meriodinal plane, the equivalent meriodinal plane (EMP) is created for any meriodinal plane. The combinations of these planes consti...

The title “Time Asymmetric Quantum Theory: the Theory of Resonances” (without questionmark) of the CFIF workshop (23.–26.7.2003, Lisbon, Portugal) implies that the theoretical description of resonances is uniquely described by the formalism of A. Bohm et al. [1, 2] reflecting the title of the workshop. Our presentation in this workshop tries to introduce an apparently inequivalent, alternative ...

——————————————————————————————————————— Abstract We investigate the single-impurity Anderson model by means of the recently introduced modified perturbation theory. This approximation scheme yields reasonable results away from the symmetric case. The agreement with exactly known results for the symmetric case is checked, and results for the non-symmetric case are presented. With decreasing cond...

Non-Euclidean traveling salesman problem (TSP) construction heuristics, and especially asymmetric TSP construction heuristics, have been neglected in the literature by comparison with the extensive e€orts devoted to studying Euclidean TSP construction heuristics. This state of a€airs is at odds with the fact that asymmetric models are relevant to a wider range of applications, and indeed are un...

Asymmetrically positioned retailers, who vary in the quality/in-store service offered, are increasingly using promotional advertising—the practice of advertising sale prices on familiar merchandise lines—to compete for customers who are willing to comparison shop. The objective of this paper is to examine the role of promotional advertising for stores that vary in their quality positioning in c...
