In an effort to assess the latest thinking in the Roman Catholic Church on economic matters, we examine the newest encyclical by Pope Benedict XVI, Caritas in Veritate (Charity in Truth) for guidance concerning marketing and business strategy. Core ethical values, consistent with historical...

Classical Wishart distributions on the open convex cone of positive definite matrices and their fundamental features are extended to generalized Riesz and Wishart distributions associated with decomposable undirected graphs using the basic theory of exponential families. The families of these...

It is shown that the information matrices of maximal parameter subsystems in linear models are linear functions of the moment matrices. With this result, design problems for maximal parameter subsystems are shown to be equivalent to design problems for the full parameter vector of a minimally...

This work aims at studying new opportunities held by Auto-ID technologies in the operation and logistic management. On the one hand, these new information technologies will speed up information flows, and on the other hand, doing the shop floor and the product flow more visible will allow...

In this article, exact D-optimal designs for a second-order response surface model on a circular design region with qualitative factors are investigated. Based on this design region, an exact D-optimal design with regular polygon structure is made up according to the remainder terms of the...
