Success of a flexible behavior. Considerations on the manufacture of Late Epigravettian lithic projectile implements according to experimental tests

It is generally recognized that the function and modality of hafting are the main factors influencing mental templates, and consequently, stone tool standardization. But what role do technical knowledge and traditions play? In this study, we investigate the interaction between mental templates and technological choices in the manufacture of Late Epigravettian projectile implements. The examined specimens come from different dwelling phases of the Dalmeri rock shelter (Italian Alps). Technological analyses suggest that lithic production systems gradually simplified their structure over time, implying a shift in technical investment from shaping on the core to a subsequent shaping on the derived flake blank. However, correlations between the dimensions and morphological features among the armatures from the different units suggest that mental templates remained unchanged throughout the Alleröd. Experimentation attests to the frequent combined application of different retouching techniques. Further, the variability in their arrangement denotes the absence of strict rules and the Epigravettian capability to recognize the most situationally suitable method. In the Dalmeri rock shelter, the standardization of lithic projectile implements is therefore a result of flexibility in retouching, framed in a production system characterized by a progressive simplification. A such rapidly produced and responsive technology must have been encouraged by Late Glacial climatic and environmental changes and the occupation of alpine territories previously inaccessible. Thus, the flexibility of technical behaviors turns out to be a key element in the transformation of Late Epigravettian societies during this period, enabling them to adapt and evolve in response to environmental, social, and economic changes.     

Charcoal scarcity in Epigravettian settlements with mammoth bone dwellings: the taphonomic evidence from Mezhyrich (Ukraine)

Fuel management during the Paleolithic periods is an important issue to understand past human subsistence. Numerous Palaeolithic sites relate an abundance of burnt bones in hearths and an absence or scarcity of wood charcoals, which leads studies to focus on burnt bone remains and the use of bones in hearths. Few works take into account the micro-residues of wood charcoals which can still be present in hearth areas and excavated sediments. We studied the Epigravettian site with mammoth bone dwellings of Mezhyrich (Ukraine) previously characterized by its high content of burnt bones and an “absence” of wood charcoal during the so-called mammoth steppe. The presence or absence and proportions of both wood charcoals and burnt bones were quantified in macro-, meso- and microscale sediment size fractions by an image analysis method. Our results show that excavations during field-works at Mezhyrich give only a partial image of the original anthracological record and that most charcoal materials are lost with standard archaeological and anthracological approaches. The scarcity of charcoals in this site was possibly due to an important mass reduction accentuated by the addition of bones in hearths. By applying our protocol we recovered a significant amount of wood charcoals which provides the first ¹⁴C dates from charcoals at Mezhyrich. Numerous charcoals are identified contributing subsequent information about vegetation, environment and burning practices. They indicate, by comparison with pollen data already collected, the presence of forest patches in a mammoth steppe landscape, which might have influenced the collecting behavior of Epigravettian populations.     

Geographical Imaginations and Spaces of Political Engagement: Examples from the Indian Alliance

This paper is concerned with the various ways in which geographical imaginations are inflected in politics. It draws on examples from a three‐way partnership of civil society organisations based in Mumbai, India. This movement seeks to reconfigure the governance of anti‐poverty strategies by placing "poor people" at the centre of its activities. The partnership, which refers to itself as the Alliance , is involved in the mobilisation and creation of a range of alternative geographical imaginations that are inflected in the production of new spaces of political engagement. By exploring two of the Alliance's strategies—enumerations and exhibitions—I will illustrate some of the ways in which these alternative geographical imaginations feature in the creation of spaces of political engagement. These strategies involve the practical demonstration of the capacities of the poor to donors and states, and reflect a particular conception of the poor and social change.
The spaces of political engagement formed in part through the Alliance's work depend significantly on a commitment to non‐party alignment, an approach that has received criticism from NGOs and commentators involved with urban poverty. I will argue that the Alliance represents a broad development alternative—rather than a form of alternative development—which nonetheless is making substantial progress in the politics of citizenship in Mumbai.     

The Vernacular Gasoline Station: Examples from Illinois and Wisconsin

Vernacular gasoline stations, those designed jointly by contractor and owner, have not shared in the recent attention directed to gasoline stations as landscape features. Instead, that growing attention has been directed largely to stations designed by architects. This study, based on extensive field survey and intensive interviews, demonstrates that the remaining vernacular gasoline stations in Illinois and Wisconsin are manifestations of special places and time, rural and small town settings between 1925 and 1940. Vernacular designing was conditioned by an uncritical reference to an archetypal gasoline station form rather than to a profit-minded manipulation of imagery. As a result, the vernacular stations were integral parts of their environments and they remain prominent landscape features clearly communicating their origins. The vernacular emphasis on form recommends the future study of the gasoline station as an architectural ensemble.     

Between east and west: Glass beads from the eighth to third centuries bce from Poland

The study analyses the chemical composition of 57 glass samples from 40 beads discovered at 20 archaeological sites in Poland. The beads are dated to Hallstatt C–Early La Tène periods (c.800/750–260/250 bce ). Analyses were carried out using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). Two groups were distinguished among the glasses based on the MgO/K₂O ratio: high-magnesium glass (HMG), five samples; and low-magnesium glass (LMG), 52 samples. The former were melted with halophyte plant ash, the second with mineral soda. These glasses were produced in the Eastern Mediterranean (more likely in Mesopotamia or Syro-Palestine than in Egypt) and transported in the form of semi-products to secondary glass workshops in Europe. Some of the white opaque glass was coloured and opacified in Europe.     

The origins of lithic projectile point technology: evidence from Africa,the Levant,and Europe

Projectile weaponry is a human cultural universal, but its origins and antiquity remain poorly understood. Stone- and bone-tipped projectile weapons have long been treated as emergent features of the "Upper Paleolithic" behavioral revolution. Recently it has been proposed that projectile technology was in widespread use among Homo sapiens populations in Africa during Middle Stone Age (MSA) times. One obstacle to researching the origins of projectile point technology is that the criteria archaeologists employ for recognizing plausible and implausible stone projectile points are largely subjective (overall tool shape, microwear traces). Tip cross-sectional area (TCSA) is a ballistically significant dimension that works well at discriminating North American stone projectile points (spearthrower dart tips and arrowheads) from spear points. This paper compares the TCSA values of ethnographic North American stone projectile points to hypothetical Middle and Upper Paleolithic stone projectile points from Africa, the Levant, and Europe. The results of this comparison do not support the hypothesis of widespread use of stone-tipped projectiles in Africa, the Levant, or Europe prior to 40 Ka. In the New World and in Australia, where we have the richest ethnographic record of stone projectile point use, these implements are largely employed in big-game hunting and in warfare. One or both of these factors may have played a role in the widespread adoption of stone projectile point technology after 40 Ka.     

Tempo and mode of formation of the Late Epigravettian necropolis of Arene Candide cave (Italy): direct radiocarbon evidence

Existing ¹⁴C dates of charcoal and bone samples from different layers of the Late Epigravettian sequence at Arene Candide (Liguria, Italy) place the formation of the deposit between 12,000 and 10,000 (uncal.) BP, but it is unclear how long this cave was used for funerary purposes. Clarifying this point has important archaeological and anthropological implications, given number and variety of inhumations. These include single and double burials of richly ornamented adults, adolescents and children and disarticulated accumulations of bones. Six new direct ¹⁴C AMS dates obtained from human skeletons place more precisely the necropolis at the Late Pleistocene-Early Holocene boundary, and appear distributed in two distinct groups that indicate two phases of funerary utilisation of the cave. Although separated by many centuries, the two phases of interment show recurring formal elements. Both groups include skeletons in anatomical connection exhibiting similar grave goods as well as chaotic accumulations of bones and, more importantly, the double burial of an adult with a child lying to its left. The reappearance of similar funerary patterns in the same site at two widely separated points in time suggests that the cave held a symbolic significance over several centuries. This, and the additional evidence of funerary use of the cave during the preceding Gravettian, points to the endurance of Upper Palaeolithic cultural traditions.     

Some Critical and Methodological Aspects of Shoreline Determination: Examples from the Baltic Sea Region

Coastal shorelines worldwide are generally unstable and changing. The study of the precise relation between any archaeological site and the shoreline at the time when the site was used is therefore complicated, but still often not met with appropriate methodological approaches. In this article, we test models based on phosphate analysis and discuss how they can be used to detect ancient shorelines. We propose that a model of increased and oscillating phosphate values at the former water level is considered reliable and useful in areas with advancing shoreline.     

Modeling Strategies for Categorical Data: Examples from Housing and Tenure Choice

Models to investigate categorical data can be divided into preprocessing, limited parameterization, and formal logit models. To illustrate the advantages of preprocessing and limited parameterization models they are applied to a data set of tenure and type of housing choice before the data are examined with hierarchical logit and nested logit models. The preprocessing approaches are useful in selecting optimal subsets of independent variables with respect to the dependent variable. The ease of application and interpretation of a limited parameterization approach extends the clarity of the results from the preprocessing approaches. Because some variables are only relevant at specific levels of other independent variables, nonstandard (nested) logit models are necessary to understand the nested relationships.     

The First Crusade and the Latin east as seen from Venice: the account of the Translatio sancti Nicolai

The Translatio sancti Nicolai is the earliest Venetian source to describe the deeds of the first crusaders from Venice. It is most likely based on an eyewitness account of the events that was later rewritten in order to provide the historical context for the translation of St Nicholas's relics to Venice. This source ambivalently depicts the nature of the crusader battles, both emphasizing the spiritual value of this fight, mainly seen as a way to fulfil the sequela Christi , and highlighting the significant economic implications of the Christian conquest of the Holy Land.     

Techniques for Integrating Macrobotanical and Microbotanical Datasets: Examples from Pre-Hispanic Northwestern Honduras

What are useful quantitative approaches in situations with highly variable data quantities, contexts, and sampling strategies? How can paleoethnobotanical findings be interpreted without over-representing data or selling results short? Described here are several major issues and potential solutions. The four sites of the study are located northwestern Honduras, a region with fairly hostile environments for paleoethnobotanical preservation. For this reason, several types of botanical residues are combined to provide a more holistic picture of past ethnobotanical practices. In some cases, these data prove to be complementary, while in others, they are corroborative. This article includes tactics for integrating multiple sample protocols, multiple and overlapping diagnostic elements, multiple and overlapping clade categories, multiple and overlapping samples in a single locus, multiple and overlapping formation processes, and multiple and overlapping cultural practices. In each section, the issue, sampling strategies, quantitative approaches, and a few results are described.     

Negotiating the Geographies of Cultural Difference in Local Communities: Two Examples from Suburban Melbourne

This paper explores the ways in which cultural difference is negotiated in local communities through the practices and actions of local individuals, groups and the policies of local government. Cultural difference is commonly managed through policies such as multiculturalism, and critiques of such policies tend to be either in terms of celebratory discourses of inclusiveness, or in negative terms which argue that such policies reiterate models of exclusivity and paternalism. The authors draw on current research in planning and cultural geography in order to explore the ways in which actual difference is negotiated at the local level through the institutional and civic spaces of local government. Two case studies for this discussion, the City of Greater Dandenong and Moreland City Council, demonstrate the importance of the physical body and its interactions with, and activities in, place to processes of local change and policy making.

乾隆时期矿政中的寻租角逐:以湘东南为例

本文通过对湘东南郴州和桂阳州矿政的讨论,揭示矿政变化背后官与商,省与州之间就矿厂管理权所发生的种种纠葛以及官办与市场之间的矛盾。本文认为乾隆年间郴桂矿政的频繁转变,与其说是追求收益率,倒不如说是不同利益主体对寻租行为控制权的争夺。在这种背景下,矿商就是包税者,而官府则充当起保护人。     

Soviet elites and European integration: from Stalin to Gorbachev

This article argues that, like the liberalising “Great Reforms” of Russia in the mid-19th century, Mikhail Gorbachev's perestroika of the late 20th century was propelled as much by reformist intellectuals' Europe-inspired visions of a more humane society as it was by military-economic crisis. Over the post-Stalin decades, a new policy-academic elite – economists, philosophers, scientists and writers – viewed in the apparent success of East European reforms a model of “socialism with a human face” for their country's eventual reintegration into a “common European home.” Yet their understanding of European integration was too superficial, and their appreciation of communist hard-liners' resistance too belated, to carry their reforms to successful completion. This article also holds that Russian reformers' naiveté was compounded by Western leaders' selfishness and short-sightedness. The latter clung to Cold War beliefs that the Soviet system could not produce a genuine reformist movement. When Gorbachev came to power, his perestroika was considered merely a “ruse,” its ideas of “new thinking” ridiculed, and ultimately only the “shock therapy” of Boris Yeltsin merited significant Western aid despite its broad incompetence and vast corruption. The combined Western-Russian failures in 1990s efforts toward rapid marketisation and integration proved even more damaging than those of the 1980s due to their broad discrediting of Western liberal democracy.     

Intra- and inter-regional knowledge spillovers: Evidence from European regions

Is the knowledge creation process linear or characterized by feedback relations among actors involved in the regional innovation system? How can the innovation process of ‘lagging’ regions be strengthened? What is the role and extent of inter-regional knowledge spillovers? The paper aims at providing satisfactory answers in investigating a knowledge production function framework adapted to the specific questions and which is tested on an extended sample of European regions. On the basis of the results, concrete policy measures are derived aiming at upgrading the knowledge creation capacity of European regions.
