Too often, scholarly research either does not reach practitioners
in a way that is usable, or the knowledge transferred is extremely
narrow, depriving practitioners of an understanding of the bigger

address a range of important questions and issues. Th ose involved
in network practice will, of course, still need to adopt the general
conclusions that we have made here to their own specific network
settings.
