- Description: This paper explores the challenges faced by small municipalities in providing water services in a developing world context of increasing urban demand. The paper uses a case study of the Sundays River Valley Municipality (SRVM) in South Africa. The municipality faces multiple dilemmas in reconciling its available water supply with growing demand for potable water in the primary urban settlement in the area, in a struggle that is typical of the broad category of South African municipalities to which the SRVM belongs. These dilemmas are explored using a system dynamics model, referred to as the ‘Kirkwood water demand system dynamics model’ (K-DEM). This paper specifically introduces the K-DEM structure,which is aimed at investigating the impacts of households progressively receiving full water and sanitation services; the use of rainwater harvesting as an alternative form of water supply; and the possible effect of a household-level water conservation / water demand management programme. Baseline results are discussed, and areas for future research identified. Paper presented at the 32nd International Conference of the System Dynamics Society, 21-24 July 2014, in Delft, the Netherlands. , Word , Mac OS X 10.8.5 Quartz PDFContext

- Description: Warehouse-scale computing supports cloud-based services such as shared disk space, computation services and social networks. Although warehouse-scale computing is inexpensive per user, the cost to entry is high, and the pressures to generate revenues to cover costs leads service providers to pursue monetizing services aggressively. In this paper, we explore some ideas for removing the need for central servers by exploiting peer-to-peer technologies.

- Description: Program Management Module was implemented after a year that Sierra was introduced in the SEALS libraries. Rhodes University had no online system for booking group study rooms. Students were queuing early in the morning outside the library so that they can sign up on a paper form for room booking. Aspects of implementation were discussed including the creation of user guidelines, training of library staff, and publicity for the booking system. Procedures were developed and made available on RUConnected and on the library webpage. , Paper delivered at the IUG-SA Conference, 19-21 November 2014.
