PUNIC INFLUENCE IN THE DOMESTIC ARCHITECTURE OF ROMAN VOLUBILIS (MOROCCO)

Roman archaeologists in North Africa have assumed that there is a generic Romano-African house, imitating the style in Rome, but perhaps with Greek influence. I argue here that at Volubilis we can detect a local tradition, drawn from a Punic heritage, which developed alongside the acceptance of Romanitas. That Volubilis appears distinct may be a product of our sample of data and other regional traditions may await identification. The relationship between architecture and action is discussed, especially in relation to seclusion. I suggest that further excavation of Punic houses in the western Mediterranean will reveal links between developments in Greek and Punic domestic architecture.     

THE SIMULATION OF URBAN SYSTEM DYNAMICS IN ATLANTIC CANADA, 1951–1991

A dynamic urban model is used to study the post-war evolution of the Atlantic Canada urban system. The computer-based simulation model is calibrated for the period 1951-86 and then employed to predict the 1991 population of each cma and ca within the system. The simulation results show that, to a large extent, the evolution of the system can be understood in terms of endogenous system dynamics rather than exogenous events. Specifically, competition among the cities of the region is a significant factor in the urban system evolution. The high degree of abstraction of the model means that data requirements for application are minimal, and the calibration procedure is relatively simple. The successful predictions show that the model can yield useful results in spite of its simplicity.
Un modèle dynamique est employé afin ďétudier ľévolution du système urbain de la région atlantique du Canada depuis 1951. Le modèle de simulation est ďabord calibré sur la periode 1951-86, et ensuite utilisé pour générer une prévision de la population en 1991 de chaque rmr et ar dans la région. Les résultats montrent que ľévolution démographique du système peut être expliqué, pour la plupart, par la dynamique inhérente du système. Plus précisement, le processus de concurrence économique et démographique entre les villes de la région est décisif; les événements exogène sont ďune moindre importance. Le modèle est plutot simple et abstrait; par conséquent, son application exige relativement peu de donnés, et le procédé calibration est relativement simple. La qualité des prévisions déographiques indique que ce genre de modèle, malgrésa simplicité peut êre utile.     

Human and Natural Controls on the Accumulation,Acidification and Drainage of Pyritic Sediments: Pearl River Delta,China and Coastal New South Wales

There is increasing concern about environmental impacts of acidic drainage from acid sulphate soils on Holocene estuarine flood plains. Acidity derives from oxidation of iron pyrite in the sediments. Natural factors determine concentrations and distributions of pyrite accumulations, but human activities have reduced pyrite accumulation in the Pearl River Delta with land use practices increasing terrestrial sediment discharge. Large freshwater discharges and management techniques have enabled sustainable use of these soils. High concentrations of pyrite occur in many estuarine flood plains of Australia because of relatively greater marine inputs. Drainage of these soils enhances pyrite oxidation and estuarine acidification, which is associated with fish-kills. For sustainable development, the problems of acid sulphate soil drainage must be recognised and overcome.     

The Making of an Australian Technoburb

North Ryde in Sydney provides an instructive case study of the emergence in little over a generation of a new suburban activity centre on a greenfield site. While its image is that of a siliconised ‘technopole’, the real significance lies in the evolution of the wider locality into some-thing more akin perhaps to an American ‘edge city’. The notion of the ‘technoburb’ seems the most apposite. The evolution of North Ryde is seen as exemplifying the restructuring of metropolitan areas into multi-nucleated regions, the strategic role of the state in setting certain ground rules for development, the rise of the information economy, the impact of globalisation of economic activity, the dependent nature of the Australian economy, and the gap that can exist between image and reality in an Australian suburban ‘hi tech’ environment.     

London-Bahrain Archaeological Expedition: 1994 and 1995 excavations at Saar, Bahrain

The long-term aim of the project is to excavate the entire central area of the Dilmun settlement. During the 1994 and 1995 seasons a further twelve buildings were excavated, most of them located along the main arteries of the settlement. A resistivity survey, followed by selective excavation, determined the size and extent of the site. A well excavated on the eastern flank provided valuable information about the level of Bahrain's aquifers in the Early Dilmun period.
