BACKGROUND Subliminal presentation of visual abandonment cues leads to greater levels of eating, despite a lack of conscious awareness of the information involved. The current study examined whether this behavioral impact can be countered by the subliminal presentation of contradictory, counterschematic information (unification cues). METHOD Ninety-six nonclinical women were presented with su...

This paper studies a multiclass queueing system with endogenous abandonments where congestion a↵ects customers’ abandonment behavior and vice versa. Our model captures this interaction by developing two closely related models: an abandonment model and a queueing model. In the abandonment model, customers take the virtual waiting time distribution as given. Class k customers receive a reward rk ...

The last decade has seen the rise of immense online social networks (OSNs) such as MySpace and Facebook. In this paper we use epidemiological models to explain user adoption and abandonment of OSNs, where adoption is analogous to infection and abandonment is analogous to recovery. We modify the traditional SIR model of disease spread by incorporating infectious recovery dynamics such that conta...

We establish heavy-traffic stochastic-process limits for waiting times in many-server queues with customer abandonment. If the system is asymptotically critically loaded, as in the quality-and-efficiencydriven (QED) regime, then a bounding argument shows that the abandonment does not affect waiting-time processes. If instead the system is overloaded, as in the efficiency-driven (ED) regime, fol...

This is a longer version of a paper with the same title, which has been submitted to Management Science. Abstract from the Journal Versionfrom the Journal Version This paper develops methods to determine appropriate staffing levels in call centers and other many-server queueing systems with time-varying arrival rates. The goal is to achieve targeted time-stable performance, even in the presence...

Abstract The endangered Yellow-headed Parrot (Amazona oratrix) has experienced a considerable reduction in abundance and distribution. Identifying natural anthropogenic causes of nest failure is critical step towards developing conservation actions that increase survival. In this study, we examined daily survival relation to temporal, habitat, factors, as well site properties. We monitored nest...

A: Abandonment of a patient may result in civil liability for the physician. Abandonment is usually defined as "the unilateral severance of the professional relationship without reasonable notice at a time when there is still the necessity of continuing medical attention." 1 Proof of actionable abandonment requires a showing that the physician failed to provide "an adequate medical attendant" a...

Title: Domicology: Human Structural Abandonment Author: Hafsa Khan Abstract: Many Midwestern cities have suffered decline, resulting in widespread residential, commercial, and industrial property abandonment. In Muskegon County, 3,312 housing units are either unoccupied, not for sale, not for rent, or are not in seasonal or occasional use. The current system of private property ownership encour...
