The first paper illustrates some of the pitfalls of assuming that the community concept is a unitary social phenomenon and argues for a social network approach to the concept. The second article explains variations in official crime rates on Indian reserves in Quebec based on the dimensions of institutional completeness and personal resource development of reserve community members. The next article reviews and evaluates successful community policing reform in Toronto in terms of police and resident agreement on the concept of neighborhood and neighborhood problems. Unresolved definitional issues surrounding the concepts of community, public order, and consensus are highlighted. Finally, the community concept is considered from the perspective of the informal social control dynamics within the highrise apartment building as a microcommunity. Focus is on the role of the building superintendent in generating rewards to the largely informal social control system and the countervailing sanctions and rewards developed by the tenants in response.
