1. CONSTRUCTING A SELECTIONIST PARADIGM

In his latest contribution to the application of Darwinian evolutionary thinking to the social sciences, W. G. Runciman conceives of human behavior as resulting from three levels of selection—biological, cultural, and social. These give rise, respectively, to evoked, acquired, and imposed patterns of behavior. The biological level is hardly controversial, but to draw a distinction between separate cultural and social selective processes is more problematic. Runciman takes memes to be the variants competitively selected at the cultural level and the practices constituting rule‐governed roles to be the variants competitively selected at the social level—thus preserving separate spheres of research for anthropology and sociology. It is not clear, however, what drives cultural and social evolution. Nor are the three levels theoretically well integrated. The book's strength lies in the numerous examples provided of how the application of selectionist theory illuminates and enriches sociological and historical explanations and contributes to the construction of historical narrative.     

Ancient DNA analysis of desiccated wheat grains excavated from a Bronze Age cemetery in Xinjiang

Wheat has been one of the most important crop in Eurasia since the Neolithic period. Understanding the spread of wheat cultivation is crucial to understanding the spread of agriculture as a whole and the interactions between prehistoric populations across the Eurasian continent. However, the routes by which wheat cultivation spread eastwards have been poorly understood to date, due to the scarcity of plant remains recovered from archaeological sites. Desiccated wheat grains excavated from the Xiaohe cemetery in Xinjiang, and dated to the early Bronze Age, show excellent DNA preservation. Here we present an ancient DNA (aDNA) analysis of wheat (Triticum sp.) grains excavated from Xiaohe and provide the first definitive evidence for bread wheat in China during the Bronze Age. The nuclear ribosomal DNA internal transcribed spacer regions (ITS1 and ITS2) and the intergenic spacer region (IGS) were amplified. The IGS region within the D genome of wheat has a 71 bp insertion that is absent from corresponding regions in the A and B genomes. The results showed that the Xiaohe wheat showed most sequence similarity to hexaploid bread wheat (Triticum aestivum), including the characteristic insertion into the D genome. The presence of bread wheat at the Xiaohe cemetery is discussed in relation to it having spread into Xinjiang by the Bronze Age, providing new insight into the origins of bread wheat in East Asia.     

Tetraethylene glycol thermooxidation and the influence of certain compounds relevant to conserved archaeological wood

The degradation of tetraethylene glycol (TEG) was studied at 70 °C under dry air and nitrogen. Degradation products were detected using gas chromatography-mass spectrometry (GC–MS). They were mono-, di- and tri-ethylene glycol, mono- and di-formates of mono-, di-, tri- and tetra-ethylene glycol and formic acid. The rate of TEG degradation was significantly decreased by approximately 10 mmol/l KI, FeCl₃, Cu(CH₃COO)₂, MnO₂ and CuSO₄, small amounts of fresh oak wood sawdust and gypsum-containing scrapings from the wood surface of the Vasa ship in Stockholm. Thus certain salts and natural components of archaeological wood are able to inhibit oxidative degradation of TEG. NaFe₃(SO₄)₂(OH)₆ (Natrojarosite), FeS₂ (pyrite), FeSO₄, Fe₂(SO₄)₃, NiCl₂, NiSO₄, Fe, Cu, Fe₂O₃, CuO, NaHSO₄ and natrojarosite-containing scrapings from the Vasa had no major effect on the rate of oxidation.     

Burning wood or burning bone? A reconsideration of flotation evidence from Upper Palaeolithic (Gravettian) sites in the Moravian Corridor

This paper compares archaeobotanical and other data from new excavations at two Upper Palaeolithic sites — Dolní V?stonice II and P?edmostí I — in the Moravian Corridor, Czech Republic. Both contain the traces of broadly contemporary ‘Gravettian’ occupations during the warmer episodes of the Pleistocene which preceded the last glacial maximum. Yet their archaeobotanical remains show striking differences — those from Dolní V?stonice II being dominated by large quantities of conifer wood charcoal, while those from P?edmostí I are much more scanty and dominated by vitrified plant remains, in association with large quantities of burnt bone. We argue that these differences between these two datasets arise from different uses of fuel at either site: bone at P?edmostí I and wood at Dolní V?stonice II. Subsequently, we explore the possible reasons for this difference and argue that once likely taphonomic distinctions are accounted for, these data on fuel use offer fresh insights into the functions and durations of these Upper Palaeolithic occupations of the Moravian corridor and some possible implications for how archaeobotanical data from such sites should be interpreted.     

Die „Vergleichende Kurortanalyse“ (VKA)

Kein touristisches Segment ist derzeit durch eine so massive Angebotsexpansion gekennzeichnet wie der Gesundheitstourismus. Allein in Deutschland versuchen sich heute mehr als 350 Heilbäder und Kurorte auf dem Markt der heiß umworbenen Selbstzahler zu positionieren. Aber auch außerhalb der Kurorte entwickelt sich das kur- und gesundheitstouristische Angebot dynamisch. Der nachfrageseitige Markt für gesundheitstouristische Dienstleistungen ist vielversprechend und hat eine weltweite Mobilisierung um den gesundheitsbewußten Touristen in Gang gesetzt. Um in diesem stark wachsenden Markt überhaupt wahrgenommen zu werden, müssen Anbieter mit einem klaren Profil erscheinen, vor allem Heilbäder und Kurorte, die ein eher traditionelles Image aufweisen. Zudem verlangen Investitionsvorhaben oder Wirtschaftsförderungen klare Entscheidungsgrundlagen der langfristigen Positionierung und Spezialisierung. Nicht zuletzt stellt sich die Frage, wie Heilbäder und Kurorte auf Destinations- bzw. Landesebene am Markt präsentiert werden müssen, um sich von anderen Bäderdestinationen zu unterscheiden. Für diese komplexe Aufgabenstellung hat das Europäische Tourismus Institut (ETI) ein abgestimmtes Erhebungs-, Bewertungs- und Analyseinstrument entwickelt, das konsequente Produkt- und Positionierungsentscheidungen für den einzelnen Kurort wie auch das Landes- oder Regionalmarketing ermöglicht. Die Vergleichende Kurortanalyse (VKA) berücksichtigt dabei sowohl die Bedürfnisse des Marktes als auch die spezifische Angebotsausstattung bzw. -attraktivität in den Orten.     

Deconstructing clusters: chaotic concept or policy panacea?

Over the past decade, there has been growing interest in localindustrial agglomeration and specialization, not only by economicgeographers but also by economists and by policy-makers. Ofthe many ideas and concepts to have emerged from this new-foundfocus, Michael Porter's work on ‘clusters’ has provedby far the most influential. His ‘cluster theory’has become the standard concept in the field, and policy-makersthe world over have seized upon Porter's cluster model as atool for promoting national, regional, and local competitiveness,innovation and growth. But the mere popularity of a constructis by no means a guarantee of its profundity. Seductive thoughthe cluster concept is, there is much about it that is problematic,and the rush to employ ‘cluster ideas’ has run aheadof many fundamental conceptual, theoretical and empirical questions.Our aim is to deconstruct the cluster concept in order to revealand highlight these issues. Our concerns relate to the definitionof the cluster concept, its theorization, its empirics, theclaims made for its benefits and advantages, and its use inpolicy-making. Whilst we do not wish to debunk the cluster ideaoutright, we do argue for a much more cautious and circumspectuse of the notion, especially within a policy context: the clusterconcept should carry a public policy health warning.     

The Debate on Globalization, Poverty and Inequality: Why Measurement Matters

In the last year or so, markedly different claims have been heard within the development community about just how much progress is being made against poverty and inequality in the current period of 'globalization'. This article provides a non-technical overview of the conceptual and methodological issues underlying these conflicting claims. It argues that the dramatically different positions taken in this debate often stem from differences in the concepts and definitions used and differences in data sources and measurement assumptions. These differences are often hidden from view in the debate, but they need to be considered carefully if one is properly to interpret the evidence. The article argues that the best available evidence suggests that, if the rate of progress against absolute poverty in the developing world in the 1990s is maintained, then the Millennium Development Goal of halving the 1990 aggregate poverty rate by 2015 will be achieved on time in the aggregate, though not in all regions. The article concludes with some observations on the implications for policy-oriented debates on globalization and pro-poor growth.
