RESPONSIBLE ACTION AND THE PROBLEM OF REIFICATION

This paper elaborates a “personal,” as opposed to an institutional, view of administrative responsibility. The idea of personal responsibility is better suited for appreciating the cognitive, conceptual, and interpersonal dynamics of policy processes than is the institutional view of responsibility as accountability. From the perspective of personal responsibility, the primary impediment to responsible action by policy makers, policy analysts, and administrators is not that they may act in ways that are ethically or morally wrong. Rather, the problem is that such actors may either not perceive that important choices are available to them or, when choices are perceived, their moral, as opposed to their instrumental, content may not be appreciated. Responsible action should thus be seen as a conceptual or cognitive issue, not simply one of adherence to or departure from institutionally objectivated standards of correctness. Inability to appreciate the moral nature of action may be explained by the cognitive tendency to reify policy making and administrative institutions, roles, rules, and situations.     

Location Modeling Utilizing Maximum Service Distance Criteria

The location set-covering problem (LSCP) and the maximal covering location problem (MCLP) have been the subject of considerable interest. As originally defined, both problems allowed facility placement only at nodes. This paper deals with both problems for the case when facility placement is allowed anywhere on the network. Two theorems are presented that show that when facility placement is unrestricted, for either the LSCP or MCLP at least one optimal solution exists that is composed entirely of points belonging to a finite set of points called the network intersect point set (NIPS). Optimal solution approaches to the unrestricted site LSCP and MCLP problems that utilize the NIPS and previously developed solution methodologies are presented. Example solutions show that considerable improvement in the amount of coverage or the number of facilities needed to insure total coverage can be achieved by allowing facility placement along arcs of the network. In addition, extensions to the arc-covering model and the ambulance-hospital model of ReVelle, Toregas, and Falkson are developed and solved.
