A partially informed expert, A, strategically transmits information to a principal, P. The residual uncertainty faced by the expert effectively causes the bias between P and A to be random, with two consequences. First, by misreporting, A is likely to induce a decision choice by P, after the resolution of the residual uncertainty, that is either close to A’s ideal position or too far from it, w...

We present the possibility that the gravitational growth of primordial density fluctuations leads to what can be considered a week version of the cosmological principle. The large scale mass distribution associated with this principle must have the geometrical structures known as a regular honeycombs. We give the most important parameters that characterize the honeycombs associated with the clo...

We consider a weak version of the cosmological principle. The large scale mass distribution associated to this principle must have the geometrical structures known as regular honeycombs. We give the most important parameters that characterize the honeycombs associated to the closed, open, and flat Robertson-Walker models. These parameters can be used to determinate by observations which is the ...

One of the major developments of twentieth century physics has been the gradual recognition that a common feature of the known fundamental interactions is their gauge structure. In this talk the early history of gauge theory is reviewed, emphasizing especially Weyl’s seminal contributions of 1918 and 1929.

Fundamental principles of precaution are legal maxims that ask for preventive actions, perhaps as contingent interim measures when relevant information about causality and harm remains unavailable, to minimize the societal impact of potentially severe or irreversible outcomes. Such principles do not explain how to make choices or how to identify what is protective when incomplete and inconsiste...

In Ohio, the principle of confidentiality embodied in the Hippocratic Oath is more than an ethical principle espoused by the medical profession.' For physicians licensed to practice within this state, by virtue of Section 4731.22 of the Ohio Revised Code, the principle is a legal obligation, the breach of which may subject the practitioner to disciplinary action up to and including revocation o...
