Presentation patterns and outcomes of patients with cancer accessing care in emergency departments in Victoria, Australia.

Purpose: People with cancer attend emergency departments (EDs) for many reasons. Improved understanding of the specific needs of these patients may assist in optimizing health service delivery. ED presentation and hospital utilization characteristics were explored for people with cancer and compared with those patients without cancer.

Coincidence measurement setup for PGAA and nuclear structure studies.

A second cold-neutron beam experimental station has been built as part of the renewal of the PGAA facility of the Budapest Research Reactor. This new station has been instrumented for neutron-induced prompt gamma-ray spectroscopy, involving gamma-gamma coincidence measurements. The experimental setup is discussed, and its performance and our data analysis method in a case of a radioactive source coincidence experiment are presented.

The effects of delayed reinforcement on free-operant responding.

In previous studies of delayed reinforcement, response rate has been found to vary inversely with the response-reinforcer interval. However, in all of these studies the independent variable, response-reinforcer time, was confounded with the number of reinforcers presented in a fixed period of time (reinforcer frequency). In the present study, the frequency of available reinforcers was held constant, while temporal separation between response and reinforcer was independently manipulated.
