For a subset of vertices S in a graph G, if v ∈ S and w ∈ V - S, then the vertex w is an external private neighbor of v (with respect to S) if the only neighbor of w in S is v. A dominating set S is a private dominating set if each v ∈ S has an external private neighbor. Bollóbas and Cockayne (Graph theoretic parameters concerning domination, independence and irredundance. J. Graph Theory 3 (1979) 241-250) showed that every graph without isolated vertices has a minimum dominating set which is also a private dominating set. We define a graph G to be a private domination graph if every minimum dominating set of G is a private dominating set. We give a constructive characterization of private domination trees.

Diversified, essentially privatised, policing options are expanding daily in modern societies. They have become available to, and are being accessed by, individuals, community groups and governments on a regular basis. While this dissertation examines the phenomenon of private policing in Australia generally, its task, more specifically, is to document and review the laws that govern, shape and make accountable private policing operations and activities. Chapter 1 reviews the origins and manifestations of contemporary shifts to privatised models of policing. Chapter 2 examines models of relationships between public and private personnel, and the various methods of accountability that may serve to govern the activities of the latter. Chapters 3 to 8 explore and explain the applicable laws that inform, shape and govern private policing generally. What this examination reveals is that "private police" are empowered by a multitude of common law and legislative principles, along with a mosaic of diverse and semi-structured rules not necessarily designed for this specific purpose. One quickly finds that the laws that permit, facilitate, regulate and manage private manifestations of policing do not fall within easily discernible legal parameters. Finally, Chapter 9 provides a summary of the dissertation, together with some general thoughts concerning the effectiveness and appropriateness of the law as a vehicle for bringing about the desired goals, namely effective policing that provides appropriate outcomes for victims, suspects, private personnel, public police and the general public alike.
