Understanding Spatial Inertia: A Comment on Tellier and Vertefeuille

In this paper we address problems regarding the applicability of themathematical statements in a recent paper in this journal by Tellier and Vertefeuille (1995). These problems have a serious impact on the conclusions drawn in the work.     

LYELL AND UNIFORMITARIANISM

T he centenary of the death of Sir Charles Lyell (1797-1875), the most notable earth scientist of the nineteenth century, was celebrated in 1975 by a special joint symposium of the International Union of Geological Sciences and the International Committee on the History of Geological Sciences. Much of what Lyell and his contemporaries regarded as "geology has become intrenched in "physical geography or in "geomorphology," so that any valid revaluation of Lyell's work is of as much significance to geographers as to geologists. It is appropriate at this time that his great contribution be recognized, but it is also a suitable occasion to re-examine some of its limitations.     

From Aachen to Al-Andalus: the journey of Deacon Bodo (823–76)

Sometime in the first six months of 838, Bodo, a palace deacon at the court of Louis the Pious, converted to Judaism, changed his name to Eleazar and removed himself to Muslim Spain. The incident is well attested in various sources although the reasons for his abandonment of Christianity are not clearly given. In 840, a year after arriving in Spain, Bodo, now Eleazar, engaged in a debate with Álvaro of Córdoba, a Christian writer and scholar living in Muslim territory who claimed to be of Jewish ancestry. Their correspondence provides illuminating insights into the framework of cultural and religious experience of this period. Bodo's self-imposed exile from Christian society is also an important rejection of the Carolingian cultural programme, a voice of protest that was probably more widespread than Carolingian society would have us believe. What follows is partly an analysis of the main textual sources that brings into relief personal, social and political themes seen to lie behind the theolo-gical debates of the period. There is also an attempt to uncover aspects of Bodo's earlier life before his conversion.     

Whither Britishness? English and Scottish people in Scotland*1

Abstract. National identity, and especially what being British means, appears to have become more problematic in recent years. Our research on national identity over the last decade suggests that people regularly construct Britishness in quite diverse ways. This article focuses on ‘territorial’ identity and points to the limits of conventional survey work on national identity. It also explores how different conceptions of Britishness are developing within Scotland and England. Differences also emerge within the group of Scots‐born nationals, as well as English‐born migrants in Scotland, as the latter come to reassess how they construct Britishness, given the new context in which they find themselves. To assume one uniform, explicit meaning of Britishness is, in short, highly problematic.     

Modeling Geographic Ferrous Scrap Markets: Regional Prices and Interregional Transactions in the United States*

Abstract. The U.S. Regional Ferrous Scrap Model analyzes spatial variations in prices for two grades of ferrous scrap using a logistic model of choice under differentiated products. The model uses a computer‐generated equilibrium framework to solve for prices that support the observed spatial distribution of supply and demand quantities. This paper presents the model's formal structure and its solution algorithm. The model specification is highly disaggregated with 1,212 supply and 240 demand regions. Characteristics of the equilibrium solution are described for prices and interregional flows. Sensitivity of equilibrium values to changes in model parameters is reported.
