Differentiation Across Standards and Adoption Failure in 56K Modems

56K modems were introduced under two competing incompatible standards. We show the importance of competition between Internet Service Providers in the adoption process. We show that ISP's were less likely to adopt the technology that more competitors adopted. This result is particularly striking given that industry participants expected coordination on one standard or the other. We speculate about the role of ISP differentiation in preventing the market from achieving standardization until a government organization intervened

African Dreams: Locating Urban Infrastructure in the 2030 Sustainable Developmental Agenda

This paper examines African urban infrastructure and service delivery as an entry point for connecting African aspirations with the harsh developmental imperatives of urban management, creating a dialogue between scholarly knowledge and sustainable development policy aspirations. We note a shift to multi-nodal urban governance and highlight the significance of the synthesis of social, economic and ecological values in a normative vision of what an African metropolis might aspire to by 2030. The sustainable development vision provides a useful stimulus for Africa’s urban poly-crisis, demanding fresh interdisciplinary and normatively explicit thinking, grounded in a practical and realistic understanding of Africa’s infrastructure and governance challenges

Analysis of a New Vehicle Scheduling and Location Problem

We consider a container terminal discharging containers from a ship and locating them in the terminal yard. Each container has a number of potential locations in the yard where it can be stored. Containers are moved from the ship to the yard using a fleet of vehicles, each of which can carry one container at a time. The problem is to assign each container to a yard location and dispatch vehicles to the containers so as to minimize the time it takes to download all the containers from the ship. We show that the problem is NP-hard and develop a heuristic algorithm based on formulating the problem as an assignment problem. The effectiveness of the heuristic is analyzed from both worst-case and computational points of view. © 2001 John Wiley & Sons, Inc. Naval Research Logistics 48: 363–385, 200

Leadership and systems of governance: The constraints on the scope for leadership of place-based development in sub-national territories

BENTLEY G., PUGALIS L. and SHUTT J. A triadic conceptualization of leadership, governance systems and central-local relations is constructed in order to aid understandings about the influence of systems of governance on the scope for place-based leadership. Deploying the dual concepts of ‘permissibility’ and ‘acceptability’ provides an innovative analytical device for deciphering the actually existing nature of place-based leadership. Recently initiated public-private-partnerships in one of the OECD’s most centralized countries are analysed to articulate characteristics of controlling mechanisms of the national system of governance which shape the degree of autonomy of leadership of city and regional development in sub-national terrains
