Economic processes and urban change: an analysis of contemporary patterns of residential restructuring

This article examines questions of explanation in urban geography through consideration of the gentrification process. Particular attention is given to the problems of ‘structural’ analyses and the need to develop alternative political economy perspectives.     

The Promise and Threat of America in Australian Politics

From early days the United States has had a curious and very entertaining career in Australia as a kind of storehouse of ideas to be raided, a powerfully justifying precedent to be invoked or a dreadful example with which to shame the thoughtless. (Cited in Churchward 1979, p. xxv)     

Thinking about security in Africa

This article attempts to clarify some of the central questions and distinctions that provide the necessary backdrop for thinking in a sophisticated way about security in Africa. Drawing on the developing Critical Security Studies literature it suggests that an understanding of security based on people, justice and change offers the surest route to a stable future. It then sketches preliminary answers to some fundamental questions, namely: whose security should be prioritized? How have security dynamics in Africa been influenced by the wider processes driving world politics? What clusters of threats are the most salient? Where do such threats have the most pernicious effects? Which actors are best placed to alleviate those threats? And what sort of institutions should be built to assist in that process? The role of outsiders concerned with promoting security on the continent should be to try to ensure that as many Africans as possible are able to voice their opinions on these crucial issues.     

COMPACTNESS AND ELECTORAL BOUNDARY ADJUSTMENT: AN ASSESSMENT OF ALTERNATIVE MEASURES

Spatial compactness has been proposed as a suitable criterion for assessing whether electoral boundaries reflect partisan interests. Although several different measures of spatial compactness have been developed, only limited efforts have been made to compare and evaluate them in the context of electoral redistricting. This paper assesses alternative spatial compactness measures and applies conceptually appealing measures to the provincial ridings proposed by British Columbia's Royal Commission on Electoral Boundaries (1988).     

PREFERENCES FOR RURAL LAND SEVERANCE POLICIES: AN EMPIRICAL ANALYSIS

The increasing demand for residential land in rural Ontario has generated a widespread interest in land severance activity and policy. This paper examines resident preferences for alternative land severance policies using a paired comparison experiment. The analysis identifies those severance policies most preferred by township residents and characterizes groups of residents with similar preferences. Differences in policy preferences are more closely associated with residents' property size, income, and length of residence in the area than with whether they are farmers, countryside non-farmers, or village dwellers.
La demande croissante d' espace résidentiel en Ontario rural est responsable pour l' intérêt grandissant envers le phénomène de détachement en parcelles et les politiques qui s'y rattachent. Le présent article examine les préférences des résidents d' un township ontarien envers différentes politiques de parcellement au moyen d' une méthode comparative. L' analyse des résultats identifie quelles sont les politiques de parcellement préférées et détermine des groupes de résidents qui ont des préférences semblables. Les différences au niveau des préférences des résidents en matière de politiques de parcellement sont plus particulièrement reliées à la grandeur des propriétés, le revenu, et la durée de résidence dans la région plutôt qu'avec leur statut résidentiel tel qu'exploitant agricole, habitant rural non-fermier, ou villageois.     

NON‐DESTRUCTIVE PORTABLE GAMMA RAY SPECTROMETRY USED IN PROVENANCING ROMAN GRANITOID COLUMNS FROM LEPTIS MAGNA,NORTH AFRICA*

Portable gamma ray spectrometry (PGRS) provides a non destructive means to analyst quantitatively large artefacts, such as building stones, for the radioelements K. U and Th. Nine Raman granitoid columns at the Leptis Magna Ruins in Windsor Great Park, London, were measured in situ by PGRS. Corrections for the environmental background contribution to the gamma ray flux measured, and for the shape and size of the columns, are described Comparison of the PGRS data with a radioelement data base for Roman granite sources indicates that most of the columns originated in the Troad area of Turkey. Two columns could not be unambiguously provenanced using PGRS alone because there is insufficient difference between radioelement concentrations in certain sources. However, non‐destructive measurements of magnetic susceptibility, used in conjunction with PGRS data, suggest that these two columns originated in the Kozak Daǧ, also in Turkey.
