THE ELEMENTAL COMPOSITION OF BENIN MEMORIAL HEADS*

Among the Nigerian cast copper‐alloy artefacts, the chronology of the Benin memorial heads has been the most fully worked out. Therefore, a study focused upon their elemental compositions is particularly likely to be interpretable in terms of development of the alloys used in their making. The elemental analyses, both published and unpublished, of 66 Benin heads, supplemented with seven analyses of some artefacts excavated from a well‐dated, very early Benin site, have been collected, analysed statistically and computed to the elemental analyses of 11 heads and figures from Udo. All but a very few of the Benin heads and artefacts separate into five compositional groups, indicating a chronological sequence of different alloying traditions. All but one of the Udo objects fall into a distinctly separate compositional group, together with two Medicine heads. The compositional groups correlate remarkably well with the stylistic types proposed by Dark.     

COLOURED OPAQUE GLASS BEADS OF THE MEROVINGIANS*

Monochrome coloured opaque glass beads of the Merovingians have been examined by different analytical methods. A large number of mostly unprepared beads have been measured by X‐ray fluorescence analysis. X‐ray diffraction was used for the identification of the crystalline colouring and opacifying pigments, and electron probe micro‐analysis as well as scanning electron microscopy were applied to study the composition and the microstructure of a white, brown, green, orange and yellow glass bead. After subtracting the content of colouring oxides of the glass beads and normalizing the residual values to 100% an identical soda‐lime‐glass matrix was obtained. The origin of the colouring metal oxides is discussed.     

An analytical study, using inductively coupled plasma (ICP) spectrometry, of samian and colour-coated wares from the Roman town at Colchester together with related continental samian wares

Over 200 sherds of samian and colour-coated pottery of late 2nd or early 3rd century date have been analysed by inductively coupled plasma (ICP) emission spectrometry. Most of this material was excavated at Colchester, England; the remainder is related East Gaulish material. Some clay samples were also analysed. The material divides, after multivariate statistical analysis, into 11 clusters. These accord well with known archaeological evidence and suggest assignments of origin where these are uncertain. In particular, the archaeological evidence for a link between Colchester and the Sinzig potters is supported.     

南唐二陵壁画历史保护修复材料的分析

为了确定南唐二陵壁画已有保护修复材料的种类,使用多光谱摄影技术分别对钦陵和顺陵壁画保护修复材料的分布区域进行探查,在紫外荧光图像中确定了保护修复材料的位置,通过红外光谱和热裂解-气质联用技术对材料进行了成分分析。结果表明二陵壁画所使用的保护修复材料主要为苯乙烯-甲基丙烯酸甲酯共聚物和聚醋酸乙烯酯,还发现少量多糖类物质,为调和地仗石灰层所使用的糯米汁。该研究表明通过多光谱摄影技术提供线索,使用红外光谱、热裂解-气质联用确定成分是一种可靠的墓葬壁画保护修复材料分析方法体系,为墓葬壁画保护修复材料的鉴别提供借鉴,也为保护修复材料在墓葬壁画中的应用效果评价和劣化机理研究提供参考。     

A Manchu itinerary

Abstract

Eighty‐nine business letters from European map sellers to the London firm of Thomas Jefferys and William Faden are preserved in the William L. Clements Library at the University of Michigan. Dating from the decade 1773–1783, the letters reveal through the invoices, accounts payable, bills of lading, and orders many detailed aspects of the map trade in the eighteenth century at the time of the War of American Independence. Special attention is drawn to the exchange of maps between England and France during this period of war.     

Entre industrie et tourisme: L'évolution du paysage baieriverain à Saguenay,Québec

Between industry and tourism: The evolving landscape of La Baie in Saguenay, Québec La Baie is a borough of the newly amalgamated city of Saguenay, which is defined by its past industrial and maritime development. This area encompassing the Ha! Ha! Bay is characterized by a lush natural landscape, contrasting sharply with the haphazardly built environment and urban fabric. The demolition of the Port‐Alfred pulp and paper mill and the cruise ship terminal project offer the possibility to improve and harmonize this former municipality's landscape. In this article, we will discuss the evolution of the borough's landscape patterns through glimpses of the maritime and tourist tradition, industrial base and the design of downtown commercial space.     

DOUBLE TRANSITIONS? REGIONAL PATTERNS OF POPULATION AGEING IN POLAND

The number and geographical distribution of the aged, and how the distribution changes over time, have captured the attention of geographical gerontologists; the complexity and spatially differentiated nature of ageing is of considerable practical and theoretical import. This article seeks to link the traditional concerns of population geography to the social and spatial relations between old people, their health and places of residence and care. It does presuppose, however, that patterns and processes at the sub‐national level are also taken into account. Therefore, the aim of the article is to identify the aged and the localities or regions where they reside, within the particular context of a Polish post‐socialist society that has recently become integrated into the European mainstream. As such it is potentially subject to a double transition, where the political and economic changes cross path with the second demographic transition. To identify interrelationships between ageing and post‐socialist transition, areas vulnerable to ageing are defined using ageing indices. Projections of the share of elderly up to 2030, based on a component cohort method, are made with a view to identifying future change in the spatial patterns of ageing. Regional patterns of ageing are presented in social, political or economic context, to show their relation to the structural changes that societies such as Poland have been passing through during the period of transition to democracy and a market economy or are likely to go through in the near future.     

Rethinking Territory

Abstract: Territory is the quintessential state space and appears to be of growing political importance. It is also a key concept in geography, but it has not been subject to as much critical attention as related geographical terms and remains under‐theorised. Taking my cue from Timothy Mitchell's suggestion that the state should be understood as the effect of social practices, I argue that the phenomenon that we call territory is not an irreducible foundation of state power, let alone the expression of a biological imperative. Instead, territory too must be interpreted principally as an effect. This “territory‐effect” can best be understood as the outcome of networked socio‐technical practices. Thus, far from refuting or falsifying network theories of spatiality, the current resurgence of territory can be seen as itself a product of relational networks. Drawing on an empirical case study of the monitoring of regional economic performance through the measurement of gross value added (GVA), I show that “territory” and “network” are not, as is often assumed, incommensurable and rival principles of spatial organisation, but are intimately connected.     

Who Counts? Dilemmas of Justice in a Postwestphalian World

Abstract: Who counts as a subject of justice? Not so long ago, it was widely assumed that those “who counted” were simply the citizens of a bounded territorial state. Today, however, as activists target injustices that cut across borders, that “Westphalian” view is contested and the “who” of justice is an object of hot dispute. This new situation calls for a new kind of justice theorizing, whose contours I sketch in this essay. Arguing, first, for a reflexive mode of theorizing, I introduce the concept of “misframing”, which can subject the Westphalian “who” to critical scrutiny. Arguing, second, for the necessity of a substantive normative principle to evaluate competing “who’s”, I introduce the “all‐subjected principle” as superior to three better known alternatives: namely, membership, humanism, and the all‐affected principle.
