WAREHOUSE FUNCTIONS, INSURANCE PLANS, AND INNER-CITY REVITALIZATION: A CANADIAN RESEARCH NOTE

The inner city contains a variety of activities that may be broadly categorized as warehouse functions. They include wholesaling, storage, and related functions of a commercial, public, or institutional nature - a miscellaneous assortment that forms a rather nebulous 'grey zone' between the more fully researched components of the urban economy, notably retailing, offices, and manufacturing. These miscellaneous warehouse functions have been primarily identified with the margins of the central business district (cbd), and particularly with the 'zone of discard,' the area of delapidation away from which the cbd core has traditionally migrated.¹ Such functions share fundamental characteristics: they are space-consuming, typically truck-dependent, concerned with market proximity, but relatively unconcerned with appearances.     

RADIOCARBON DATES FROM THE OXFORD AMS SYSTEM: ARCHAEOMETRY DATELIST 3

This third list of accelerator dates includes material dated in the same period as datelist 2 (Gillespi?et al. 1985) and subsequently. The dates have been achieved by the same methods as described there.     

Urban Neighborhoods as a National Resource: Irreversible Decisions and Their Equity Spillovers

The differential timing and pace of private versus public sector disinvestments in declining neighborhoods have some positive spillovers for their residents. Public services are not withdrawn or reduced as rapidly as private investments and the opportunity is preserved for future redevelopment or rehabilitation. This “public service bonus” is vulnerable, however, during periods of austerity and general retrenchment. During such crises, the pressures to rationalize service provision are able to overcome local political and bureaucratic resistance to service reallocations. The analysis is based upon the investment theory literature dealing with irreversible decisions and is exemplified by the reallocation of services in New York City's declining neighborhoods during the past decade.     

Activity Levels at Hub Facilities in Interacting Networks

Hubs are a special type of central facility which are designed to act as switching points for intemodal flows. For instance, a set of ten interacting cities might all be connected to one of two major hubs. All flows between the cities would then be routed via the hubs. There is an obvious saving in the number of routes necessary to interconnect the cities when hubs are utilized, with a concomitant high level of activity at the facilities. This paper takes a heuristic approach to the evaluation of networks and hub locations to find locally optimal designs. It is shown that minimization of transportation costs may require assignment of nodes to a facility other than the nearest. A discount on the interhub transportation costs promotes a wider spacing of facilities. In a system with several hubs, minimization of total hub usage tends to concentrate demand very heavily into one central facility.
