Maximum exercise testing using treadmill walking and cycle ergometry was compared in 40 male patients who had suffered a myocardial infarction in the preceeding twelve months. Maximum oxygen uptake was on average 17% greater in the treadmill than the cycle test and maximum heart rate was also higher, but the rate pressure product (RPP) was a similar due to(More)
Phosphorylation is a mechanism by which cells regulate structure and function of proteins. We have previously demonstrated in vivo synthesis and secretion of phosphorylated bovine prolactin (bPRL) from the pituitary, and have isolated and partially characterized the phosphorylated bPRL. In order to investigate the structure/function role of phosphorylation(More)
Previous research on the theory of planned behavior (TPB) is characterized by cross-sectional tests of the model's proposed causal relationships. In the absence of effective experimental techniques for changing the TPB's cognitive antecedents, the present research aimed to provide a stronger non-experimental test of the model, using causal analyses of(More)
One of the proposed solutions to the equilibrium selection problem for agents learning in repeated games is obtained via the notion of stochastic stability. Learning algorithms are perturbed so that the Markov chain underlying the learning dynamics is necessarily irreducible and yields a unique stable distribution. The stochastically stable distribution is(More)
The authors express their appreciation to Luisella Goldschmidt-Clermont for very helpful suggestions. Abstract: Person care, of which care of children is the major component, has not been previously measured by the output approach to valuation. This study measures person care using the output method with sample data from a small urban area and compares the(More)
BACKGROUND Cardiorespiratory fitness measured by treadmill testing has prognostic significance in determining mortality with cardiovascular and other chronic disease states. The accuracy of a recently developed method for estimating maximal oxygen uptake (VO2peak), the heart rate index (HRI), is dependent only on heart rate (HR) and was tested against(More)
