The changing nature of the peri‐urban zone in Africa: Evidence from Dar‐es‐Salaam,Tanzania

Research on the peri‐urban zones of African cities since the mid‐1980s has focused around three main themes, these being peri‐urban agriculture as a survival strategy, debates about the relative efficiencies of peri‐urban agriculture, and the question of production priorities. Drawing on recent evidence from Dar‐es‐Salaam in Tanzania, this paper suggests that a combination of structural adjustment measures and the eased economic crisis in Tanzania has changed conditions, the result of which has been the increasing commodification of land in the peri‐urban zone during the 1990s. This has turned the peri‐urban zone more into a zone of investment and economic opportunity, rather than a zone of survival, with the result that the poorer urban groups are being increasingly excluded. A further complication concerns confusion arising out of current Tanzanian land law, and particularly the tensions between customary and statutory law.     

Sewn Boats of Southeast Asia: the stitched‐plank and lashed‐lug tradition

This article updates research into the sewn‐boat traditions of Southeast Asia with recent finds that provide evidence of the transition from stitched planks with lashed‐lug frames to planks fastened with dowels and locked dowels alongside lashed‐lug frames. The differences between Southeast Asian, East Asian, and Indo‐Arabic boatbuilding are discussed and the meaning of anomalies, such as the Maldivian dhonis, examined. Considering the known history of trade and exchange throughout the South China Sea and the Indian Ocean, the lack of hybridization between boatbuilding traditions is noted.     

Logboats from Europe and the CD-ROM, or a solution to the endless search for documents (2000 edition)

Bibliographic data capture of logboats from Europe is available as a database which includes more than 6000 pictures or files (corresponding to the same number of A4 pages): as the result of the processing of 700 works dealing with 2400 logboats; 6500 links were established between those logboats and bibliographical references.     

Human remains from a post‐Hellenistic grave‐chamber in Dibba al‐Hisn (Sharjah,UAE)

Human skeletal remains of sixteen individuals found at Dibba al‐Hisn in the Emirate of Sharjah (UAE) are analysed with regard to standard anthropological criteria. They represent the poorly known pre‐Islamic period of the first centuries AD. Remains of at least fifteen individuals were recovered from a semi‐subterranean grave‐chamber together with rich archaeological grave‐goods. An additional, almost complete skeleton was found in the open area near the chamber. While the size and nature of the sample prevent demographic analyses, skeletal features studied with the help of macro‐ and microscopic as well as radiographic methods provide details on individual life histories and living conditions, as well as mortuary habits and taphonomic processes. Of special interest is a case of intentional tooth mutilation as well as two cases of skull trauma apparently caused by violent inter‐personal conflict. The results of the analysis of the faunal remains from the grave‐chamber and its surroundings are presented in an appendix .     

Extracting sovereignty: Capital, territory, and gold mining in Tanzania

In contemporary discussions of “resource nationalism,” sovereignty is often imagined as the exclusive control of national states over internal resources in opposition to external foreign capital. In this paper, we seek to draw attention to the specifically national territorial forms of sovereignty that - rather than hindering the flow of capital - become constitutive to the accumulation of resource wealth by states and capital alike. Drawing from political geographical theorizations of sovereignty, we argue that resource sovereignty cannot be territorially circumscribed within national space and institutionally circumscribed within the state apparatus. Rather, sovereignty must be understood in relational terms to take into account the global geography of non-state actors that shape access to and control over natural resources. Specifically, we engage national-scale state sovereignty over subterranean mineral resources in the form of legal property regimes and examine the mutually constitutive set of interdependencies between mining capital and landlord states in the accumulation of resource wealth. Using Tanzania as a case study, we argue that national-scale ownership of subterranean mineral resources has been critical to attracting global flows of mining capital from colonial to contemporary times. We first examine the history of the colonial state in Tanganyika to illustrate how land and mineral rights were adjudicated through the power of the colonial state with the hopes of attracting foreign capital investment in the mining sector. We then examine contemporary efforts on the part of the independent United Republic of Tanzania to again enact legislation meant to attract foreign mining companies - and the consequences for local populations living near sites of extraction.     

Sewn Boats in Oman and the Indian Ocean

Sewn boats have been ubiquitous across the globe throughout history (Greenhill and Morrison, 1995: 118) and fibre and wood were the fundamental boatbuilding materials in the Oman peninsula for millennia. Evidence for their use appears in the archaeological record in the 3rd millennium BCE but the level of technical development plus the archaeological record of international trade, suggest a much longer history. This paper reviews elements of the information from historical texts, ethnography, and archaeology in a synthesis to broadly outline the development and characteristics of sewn boats in the Indian Ocean.     

Re‐equilibration of fluid inclusions in diagenetic‐anchizonal rocks of the Ciñera‐Matallana coal basin (NW Spain)

Thermally re‐equilibrated fluid inclusions are reported in natural fissure quartz (qtz1) from polymineralic veins in the diagenetic‐anchizonal clastic sedimentary rocks of the Ciñera‐Matallana coal basin (Variscan, NW Spain). Euhedral quartz formed during early fissure opening from an immiscible fluid mixture composed of a low salinity aqueous solution and a CH₄‐rich vapour phase, at temperatures of about 110–120°C and pressures ranging from 15 to 56 MPa. Five textural types of re‐equilibration are recognised in progressive order of inclusion modification: scalloped, hairy, annular‐ring shaped, haloes and decrepitation clusters. These textures resulted from a combination of brittle fracturing and dissolution and re‐precipitation of quartz, with preferential loss of water. The thermal peak was short‐lived, but was high enough to induce extensive decrepitation of fluid inclusions in vein quartz throughout the entire basin. Enhanced temperatures can be related to the intrusion of diorites in the basin. Careful analysis of textural features in fluid inclusions from diagenetic and very low‐grade metamorphism environments constitutes a useful tool for recording basin thermal history.     

ANALYSING ARCHAEOLOGICAL BASALT USING NON‐DESTRUCTIVE ENERGY‐DISPERSIVE X‐RAY FLUORESCENCE (EDXRF): EFFECTS OF POST‐DEPOSITIONAL CHEMICAL WEATHERING AND SAMPLE SIZE ON ANALYTICAL PRECISION*

Energy‐dispersive X‐ray fluorescence (EDXRF) has been commonly used to determine geological sources of volcanic glass artefacts, but its ability to discriminate between basaltic sources is less developed. We examine the precision and accuracy of non‐destructive EDXRF for basalt artefacts by analysing varying size and weathering characteristics. The experiments identified no appreciable effect in reproducibility or measured composition due to thickness (down to 1 mm) or natural weathering of pre‐contact flake scars for the 17 elements measured in this study. Samples with surface area less than 100 mm², however, show significant variability in measured composition and reproducibility.     

The ethno‐religious ambitions of the Roman Catholic Church and the ascendancy of communism in post‐war Poland (1945–50)

ABSTRACT. This paper differentiates between centrifugal and centripetal aspects of ethno‐nationalism to help account for the ascendancy of communism in the immediate aftermath of World War II in Poland. It argues that the directing of social antipathy to defined out‐groups allowed the Polish Workers' Party (PPR) to manage social anger and that the Roman Catholic Church's ethno‐religious agenda was aligned with the PPR's ethno‐nationalist policy. Furthermore, it is contended that the Church's toleration of hostile actions directed at minority communities supported the PPR's management of social anger. The paper concludes that the Church, despite its manifest intentions and contrary to contemporary perceptions, played a role in the PPR's achievement of hegemony.     

Discursive Agency: (Re‐)Conceptualizing Actors and Practices in the Analysis of Discursive Policymaking

Interpretive discourse analysis commonly claims to address the interrelation between actors and discourses. However, the analytical focus of most approaches is on structures (discourses) while much less attention is paid to agency. This paper explicitly addresses discursive agency in two steps. First, we systematically review theoretical and analytical dimensions of agency in existing interpretive discourse analysis approaches. This review reveals a set of shared assumptions; most notably a concept of “trialectic” agency emphasizing the constitution of agency among the individual, the (discursive) structures, and the researcher's interpretation. Second, we propose an analytical heuristic, the Discursive Agency Approach, which is developed on the basis of the review and own empirical data. The proposed approach consists of four elements: (1) policy discourses, (2) political institutions, (3) agents defined via a set of characteristics, and (4) strategic practices. This approach is meant to facilitate a systematic exploration of agency under a discourse perspective, tackling the question of how a policy is constituted through the agency ascribed to its proponents in dynamic discursive processes, and how actors acquire political relevance through discursive means. To enable this goal, we propose distinct research steps and associated methods that link the approach to existing means of analysis.     

ARCHAEOMETRIC INVESTIGATIONS OF SGRAFFITO CERAMIC TILES (FIFTEENTH‐SIXTEENTH CENTURIES) RECOVERED FROM EXCAVATIONS IN UDINE (NORTH‐EAST ITALY)*

Most of the Renaissance sgraffito tiles excavated in Udine (Italy) constitute a homogeous group, the tile body having a CaO/MgO molar ratio ?= 3:2. They were produced using a dolomite‐ and calcite‐containing clay fired at 900–950°C. A small group of samples, with a lower firing temperature and a CaO/MgO ratio ?= 2:3, was probably produced in a different factory. Slip and transparent glaze, characterized by optical microscopy and inductively coupled plasma atomic emission spectrometry, are an illite‐rich clay and a lead silicate, respectively.     

Sulfosalt melts and heavy metal (As‐Sb‐Bi‐Sn‐Pb‐Tl) fractionation during volcanic gas expansion: the El Indio (Chile) paleo‐fumarole

High‐sulfidation vein gold deposits such as El Indio, Chile, formed in fracture arrays <1000 m beneath paleo‐solfatara in volcanic terranes. Stable isotope data have confirmed a predominance of magmatic vapor during the deposition of arsenic‐rich sulfide–sulfosalt assemblages in this deposit. These provide a unique opportunity to analyze the processes and products of high‐temperature volcanic gas expansion in fractures that form the otherwise inaccessible infrastructure deep inside equivalent present‐day fumaroles. We provide field emission scanning electron microscope and LA‐ICP‐MS micro‐analytical data for the wide range of heavy, semi‐metals and metalloids (arsenic, antimony, bismuth, tin, silver, gold, tellurium and selenium) in the complex pyrite‐enargite‐Fe‐tennantite assemblages from Copper Stage mineralization in the El Indio deposit. These data document the progressive fractionation of antimony and other heavy metals, such as bismuth, during crystallization from a sulfosalt melt that condensed from expanding vapor at about 15 MPa (150 bars) and >650°C following higher temperature vapor deposition of crystalline pyrite and enargite. The sulfosalt melt aggressively corroded the earlier enargite and pyrite and hosts clusters of distinctive euhedral quartz crystals. The crystallizing sulfosalt melt also trapped an abundance of vugs within which heavy metal sulfide and sulfosalt crystals grew together with K‐Al silicates and fluorapatite. These data and their geologic context suggest that, in high‐temperature fumaroles on modern active volcanoes, over 90% of the arsenic content of the primary magmatic vapor (perhaps 2000 mg kg^?1) was precipitated subsurface as sulfosalt. Subsurface fractionation may also account for the range of exotic Pb‐Sn‐Bi‐Se sulfosalts observed in fumarole sublimates on active volcanoes such as Vulcano, Italy, as well as on extra‐terrestrial volcanoes such as Maxwell Montes, Venus.     

Vietnamese (15th Century) Blue‐And‐White,Tam Thai and Lustre Porcelains/Stonewares: Glaze Composition and Decoration Techniques*

EDS, X‐ray fluorescence, Raman spectroscopy, thermal expansion–shrinkage measurement and scanning electron microscopy were applied to determine the elemental components, structural phases and glazing temperatures of the transparent glazes, blue underglaze and overglaze tam thai (including gold‐like lustre) decorations from the 15th‐century Vietnamese porcelains/stonewares found at the Chu Ðâu–My Xa kiln site and in the Cù Lao Chàm (Hôi An) cargo. The ancient technology for colouring the glazes is discussed. The various blue tones in the underglazed décor result from cobalt‐containing manganese ore, with the intentional addition of iron oxide. The overglaze copper‐green and the gold‐like lustre were obtained by dispersing copper in lead‐based glass. The red colour was made using hematite dispersed in lead‐rich flux.     

A Study Of The Firing Technique Of Pottery From Kaman‐Kalehöyük,Turkey, by Synchrotron Radiation‐Induced Fluorescence X‐Ray Absorption Near‐Edge Structure (Xanes) Analysis*

Fe K‐XANES spectra of a series of pottery sherds excavated from the archaeological site of Kaman‐Kalehöyük, Turkey, were measured to reveal the firing technique of the pottery. The analysis disclosed relationships among the chemical form of the iron, the firing conditions and the colour of the pottery. The pottery referred to as ‘Grey Ware’ found at this site was classified into two groups according to the chemical form of the iron. Also, it was revealed that the Iron Age pottery referred to as ‘Cream Ware’ was produced first under reducing conditions, and then fired under oxidizing conditions.     

Muhammad Abd al‐Rahman (Phillip) Barker: Bridging Cultural Divides through Fantasy/Science‐Fiction Role‐Playing Games and Fictional Religion

“Muslims” and “Dungeons & Dragons” are rarely discussed in the same sentence. However, one of the earliest fantasy role‐playing games, which left a lasting impact on the industry, was the brainchild of Muhammad Abd al‐Rahman (Phillip) Barker (1929‐2012), a professor of South Asian Studies, an expert in Native American languages, and an American convert to Islam. Like Tolkien, Barker created an enormous fantasy world; however, unlike Tolkien, his world was redolent with Native American and South Asian cultural and religious influences. Through this world, he shared with his fans a nuanced understanding of non‐Western societies, cultures, and beliefs – the facets of the human experience that truly constitute multiculturalism. While fictional religion in role‐playing games has been feared and condemned, fictional religion (and occultism) plays a pivotal role in Barker's work; an exploration of his approach towards fictional religion also sheds more light on the question of why fantasy role‐playing games came across as competitors towards religion. Barker's fantasy world brought people of diverse backgrounds together in a beautiful demonstration of how fantasy and science fiction can bring about intercultural and interreligious tolerance in an otherwise intolerant world. Given the centrality of games such as Dungeons & Dragons to American popular culture, an exploration of Barker's legacy can also be seen in the light of the study of the history and contributions of Muslims in America.     

Threading a needle: Kazakhstan between civic and ethno‐nationalist state‐building

This paper examines the state‐building project in Kazakhstan since independence in 1991. It argues that both civic and ethno‐nationalistic tendencies in state‐building can be identified but that it is not any particular trajectory of nationalism in Kazakhstan that is of significance so much as the tensions between two very different trajectories. We argue that, at least to date, the government has succeeded in managing these tensions quite effectively both at the policy level and in its relations with different ethnic groups and neighbouring states. Whether Kazakhstan can continue to manage these tensions in the post‐Nazarbayev era is one of the most significant questions facing the country.     

Independence and Corporations in Pre‐Reform Freeman Boroughs: A Case Study – Newcastle‐under‐Lyme in the 1810s

This article draws on a wide range of evidence – corporation records, pollbooks, newspapers, squibs and broadsides, and private correspondence and accounts – to put forward some significant revisions to the electoral history of the borough of Newcastle‐under‐Lyme in the early 19th century. In the process, the article contributes to our understanding of the conflict between ‘oligarchy’ and ‘independence’ which characterised politics in this and other freeman boroughs. The independent party in the town emerges as a powerful force in its own right, one which came to monopolise access to the ‘rhetoric of independence’, rather than being a mere vehicle for ambitious candidates. The ability of the corporation to influence events by manipulation of the voting roll is also reassessed, and is seen to have been less significant than has been supposed.     

The Mollö Cog Re‐Examined and Re‐Evaluated

As part of a research project on medieval trade and maritime transportation in the former Norwegian province of Bohuslän, western Sweden, a dendrochronological analysis of the so‐called Mollö cog was undertaken. The wreck, which was first salvaged in 1980, was previously dated by ¹⁴C analysis. Since this provided a nearly 400‐year time‐span for the building of the vessel, a more precise dating was considered essential. In conjunction with dendrochronological sampling, several features not previously reported were recorded. This paper presents the find, the research history and the results of the dendrochronological investigation. © 2012 The Authors     

Social distance in Bosnia‐Herzegovina and the North Caucasus region of Russia: Inter and intra‐ethnic attitudes and identities*

ABSTRACT. This article examines attitudinal differences and similarities among ethnic groups in conflict‐affected societies. Conventional wisdom tells us that societies that have experienced violent struggles in which individuals of different ethnic groups have (been) mobilized against each other are likely to become polarized along ethnic lines. Indeed, both policy‐makers and scholars often assume that such divisions are some of the main challenges that must be overcome to restore peace after war. We comparatively examine this conventional wisdom by mapping dimensions of social distance among 4,000 survey respondents in Bosnia‐Herzegovina and the North Caucasus region of Russia. The surveys were carried out in December 2005. Using multidimensional scaling methods, we do not find patterns of clear attitudinal cleavages among members of different ethnic groups in Bosnia‐Herzegovina. Nor do we find patterns of clear ethnic division in the North Caucasus, although our social distance matrices reveal a difference between Russians and ethnic minority groups.
