UNLABELLED Candidates with fulminant hepatic failure (Status-1A) receive the highest priority for liver transplantation (LT) in the United States. However, no studies have compared wait-list mortality risk among end-stage liver disease (ESLD) candidates with high Model for End-Stage Liver Disease (MELD) scores to those listed as Status-1A. We aimed to determine if there are MELD scores for ESLD...

Description of several well-documented applications of no-wait or blocking scheduling models and illustration of some ways in which the increasing use of modern manufacturing methods gives rise to other applications. Review of the computational complexity of a wide variety of no-wait and blocking scheduling problems which remain open as to complexity. Study of several deterministic owshop, jobs...

PROBLEM ADDRESSED Patients have to wait too long to see their family physicians. Open access, a new approach to office scheduling, has shown promise in reducing patient wait times to see primary care physicians. OBJECTIVE OF PROGRAM To offer same-day appointments to most patients who call the office, thus reducing wait times as measured by the third available appointment. Reductions in no-sho...

BACKGROUND The demand for total hip and total knee arthroplasties is increasing as are the waiting times for these procedures. Because of the differences between rural and urban areas in terms of the provision of arthroplasty services and between the 2 patient groups, patient perspectives of waiting times may also be different. METHODS To compare waiting times for initial orthopedic consultat...

This article reports of two studies addressing the meaning of primary and secondary control beliefs for transition to modernity and modern adoles­ cents. Study 1 participants (N = 365) were Malaysian (transition to mod­ ernity), and German and North American (modern) adolescents. Study 2 participants (N = 757) were Israeli Druze (transition to modernity) and Israeli Jewish (modern) adolescents....

We give a graph theoretical proof for the existence of a walk connecting left and right sides of a rectangle when it is partitioned into (finitely many) rectangles colored in a specific way, and the walk is aloud to use only borders between rectangles of different color. The problem was originally introduced by J.R. Isbell in the proof of his Zig-Zag Theorem. We prove the existence of such a wa...
