A Core-Periphery GIS Model of the Historical Growth and Spread of Islam in China

Abstract

This study presents the methodology and results of a core-periphery GIS model of the historical growth and spread of Islam in China based on a dataset of 1,774 mosques. These sites were organized into data subsets according to their founding dates during five major dynastic periods in Chinese history: Tang/Song, Yuan, Ming, Qing, and Republican. Core areas were identified and mapped based on where mosques clustered during each period. North China was the paramount core region in all periods. Not until the late Qing and Republican periods did the Northwest and Yunnan compare with North China, while coastal China never developed into a core area.     

THE GOVERNMENT’S BUSINESS?

The engagement of Swedish industry in the Liberian American–Swedish Minerals Company (LAMCO), which mined iron in Liberia between 1963 and 1989, was the largest Swedish commercial investment in Africa during the Cold War. In this paper I investigate how political and administrative actors of the Swedish government conceptualized the link between private and public interests in the context of LAMCO’s operations, and how this shaped Swedish government policy towards the company and Liberia. I identify two phases: a phase of almost unanimous political support for LAMCO and close Swedish–Liberian relations from ca. 1955 to 1965, and a more fragmented phase following 1965, during which LAMCO was increasingly understood as a political liability. My findings show how business interests could figure into Swedish foreign policy during the Cold War, highlighting the coherence with which Swedish industry and government acted in relation to the commercial interests in Liberia before ca. 1965, but also the lack of coherence – between government and industry as well as within the state apparatus – that followed the turn to a more activist policy after the mid-1960s.     

Urban geo-archaeology in medieval alzira (Prov. Valencia,Spain)

Alzira is situated in a cut-off meander loop of the Rio Júcar. Geo-archaeological study shows that the Islamic city wall was built during the second quarter of the 11th century AD, at a time when the river had a low-amplitude and low-energy flood regime. After mid-century, overbank silts began to invade the city as peak flood discharge increased, with a spate of destructive floods reflected by high-energy deposits during the late 11th century. Urban expansion within the city wall is dated to the later 11th or early 12th century, interrupted by local abandonment and moderate-energy flood silts. Major construction during the mid-12th century was followed by protracted abandonment (after a siege in AD 1171?) and further, moderate-energy flood silts that redistributed occupation and collapse debris. Reoccupation, during the late 14th century, was terminated by catastrophic floods in 1517 and 1571, after which much of the western end of Alzira was not rebuilt. Following further flood catastrophes during the 17th century, parts of the central walled city remained abandoned until the 19th century. with new occupation atop flood sands of yet another disaster in 1864. The change in flood regime after 1150 was a result of deforestation of the watershed, but progradation of a downstream tributary fan after 1517 created an unstable, aggrading floodplain increasingly prone to severe flooding. Climatic anomalies were responsible for periods of recurrent severe floods, archaeologically verified during the 11th and 12th centuries, and historically documented, beginning in 1318. The geo-archaeological methodology illuminates the constructional and settlement history of Alzira, allows distinction of fluvial and cultural components, and provides the necessary microstratigraphic detail and dating control to document the true complexity of alluvial processes during the last 1000 years.     

An alternative approach to zoning in France: Typology,historical character and development control

The paper describes an approach to development control taken in France, bringing together the zoning system of planning and geographical and architectural studies of urban form. The approach addresses a number of issues, in particular the maintenance of the historical and regional character of towns, often eroded under systems of land‐use zoning. The principles and methods of the approach are set out and its application is illustrated by an example, illuminating both the approach and the context in which it was realized.     

Food Markets in the Eastern Highlands, Papua New Guinea: Actors, Power and Rural Development Geography

Discussions of rural development in the highlands of Papua New Guinea have often centred on coffee, and been couched either in narrowly economic terms or in class analysis terms. Fresh food marketing has received less attention, although it is an important activity for many highland people. An approach which takes into account the subjectivity of actors, and the contests of power which permeate markets, is explored in this paper. The history and present forms of fresh food marketing in the Eastern Highlands Province of Papua New Guinea are then outlined. The author concludes by arguing for a geography of rural development, which is based on close attention to social interaction at the local level, coupled with an awareness of global structures provided by non-universalist political economy.
