In this paper we characterize pairs of Rosenberg relations (ρ, σ) with the property that the endomorphism monoid of one of the relations is properly contained in the endomorphism monoid of the other relation. We focus on the situations where one of the relations is a partial order, or a central relation. AMS Mathematics Subject Classification (2000): 08A35, 06A06

The notion of a good quotient relation has been introduced as an attempt to generalize the notion of a quotient algebra to relations on an algebra which are not necessarily congruence relations. In this paper we investigate some special classes of good relations for which the generalized versions of the well-known isomorphism theorems can be proved.

This paper explores possibilities for using recent formulations of social positioning theory to interpret relationship dynamics in a biomedical engineering laboratory. As a linguistic phenomenon, positioning is most commonly analyzed in person to person or group to group interactions (or person to group). We here extend analysis of positioning to include person to object or person to artifact r...

This paper presents the development of a novel framework that optimizes the evacuation of large cities using multiple modes including vehicular traffic, rapid transit, and mass transit shuttle buses. A large-scale evacuation model is developed for the evacuation of the City of Toronto in cases of emergency. A demand estimation model is first designed to accurately quantify the evacuation demand...

The social sciences are paying increasing attention to relations. In contributing to this ongoing dialogue and debate Educational Leadership Relationally (Eacott, 2015) articulates a relational research program for the study of educational administration and leadership. This paper provides an overview of the relational program with particular attention to the five central tenets of the methodol...
