When a conscious observer is part of a quantum mechanical system, rule (4) cuts off solutions to the Schrdinger equation. It is important to show that this interruption of the Hamiltonian dynamics does not effect the statistical predictions of the theory. The initial case considered is that of a two atom radioactive source. It is found that when the predictions of standard (Born rule) quantum t...

Sunspot equilibrium and lottery equilibrium are two stochastic solution concepts for nonstochastic economies. Recent work on nonconvex exchange economies has shown that when the randomizing device is a continuous random variable, applying the two concepts to the same fundamental economy yields the same set of equilibrium allocations. In the present paper, we examine economies based on a discret...

Predictions of isobaric and Regge models are compared with the latest experimental data (Bonn, JLab) to select among the models those providing a satisfactory description of the data. Only the Saclay-Lyon (SLA) and MAID models are in a reasonable agreement with both photo-and electro-production data ranging up to about E lab γ = 2.5 GeV. In this energy region the Regge model is suitable only fo...

The family and the church have been the most important institutions in African American families and communities since slavery. African American grandmothers have played a pivotal role in both institutions. Their role responsibilities, especially in the extended family context, are broad and elastic. They have performed crucial roles in the care and welfare of grandchildren, great-grandchildren...
