Neutron activation analysis of stone from the Chadron Formation and a Clovis Site on the Great Plains

Cryptocrystalline silicates from the Chadron Formation were widely used by prehistoric human groups in the Great Plains of North America. There are two documented quarry areas: Flattop Butte in Colorado and the White River Badlands of South Dakota. Cryptocrystalline silicates from these sources are visually indistinguishable, making it difficult to determine the sources of artefacts found at archaeological sites. In this investigation, neutron activation analysis is used to distinguish the two sources. This technique also identifies lithic material from the Clovis-age Eckles site in Kansas as being from Flattop Butte.     

When regional innovation policies meet policy rationales and evidence: a plea for policy analysis

In spite of recent advancements regarding regional innovation policy rationales and evidence, there are few analyses about the actual features of existing regional innovation policies. Nevertheless, a policy analysis perspective is important in order to recognize their distinctive patterns across regions, and to understand how rationales and evidence can be translated into policy-making. To this purpose, this paper develops a framework to study the extent to which regional innovation policies have changed during the past few years. Since the mid-2000s, there has been an important development of innovation policy rationales, advocating for more specialization; likewise, greater data availability at the regional level has allowed more sophisticated assessment of innovation performance. Finally, the crisis since 2008 has had ravaging effects in some regions, with job losses and severe economic sluggishness. Therefore, it is reasonable to expect transforming dynamics in regional innovation policies. Against this backdrop, the paper compares the institutional frameworks and budgetary priorities of four Spanish regions during the period 2001–2014: Catalonia, the Basque Country, Galicia and Andalusia. In so doing, it aims at studying the extent to which regional governments have readily addressed past and new challenges related to their regional innovation system, and if so, how.     

Policy Bubbles

We develop the concept of a policy bubble to capture the notion of long‐term overinvestment in a policy. In sketching the relation of policy bubbles to economic bubbles, we describe how these two concepts have similar origins but different trajectories because they are filtered by different institutions. We examine in some detail three likely instances of ongoing policy bubbles: crime policy, school reform (charter schools and private education vouchers), and the contracting and privatization of public services. We show how these cases differ from the housing bubble of 1997–2007, how they differ from each other, and the extent to which they can be considered policy bubbles. Last, we suggest this concept can help unify the policy process literature with the practice of policy evaluation and outline testable hypotheses for future research.

Interpreting pachyderm single carcass sites in the African Lower and Early Middle Pleistocene record: A multidisciplinary approach to the site of Nadung’a 4 (Kenya)

Nadung’a 4 is one of the single carcass pachyderm sites recorded in East Africa during the Lower and Early Middle Pleistocene. The site has yielded an abundant lithic assemblage in close association with the partial carcass of an elephant. Conjoined pedological, geoarchaeological, spatial, technological, and taphonomical analyses have been carried out to address the relationship between hominids and elephant. The resulting data are consistent with a non-fortuitous association between both categories of remains. The lithic artefacts do not match a classical Acheulean tool-kit, as would be expected for the time period ascribed to the site, and the functional patterns inferred from their analysis make this site radically different from other purported butchery sites. The implications of these original features are discussed.     

<Emphasis Type="Italic">Corrales de Indios</Emphasis> (Lithic Structures) in Tandilia,Argentina: A Global Study

In the central-southeastern area of Buenos Aires Province, Argentina, lies a mountainous area of low height in Tandilia that contains important outcrops of quartzite and granite. A large number of buildings are made of massive blocks of rock, some of them with a surface of over 1 ha. In addition to these completely artificial constructions are other structures that are semi-natural, having been made in places with special topographical characteristics and complemented with dry-stone walls. Scanty written documents allow us to attribute some of the constructions to an age before the permanent settlement of the Creole population. In the Tandilia Sierras these structures are commonly known as “corrales de indios” (Indian corrals). This designation involves a double prejudice with regard to function and cultural affiliation. Out of a total of 22 structures, we analyze a group of 4 that were excavated to use to review the written documents.     

The When, Where, and How of Novices in Craft Production

Archaeologists frequently underestimate the importance of children as well as craft skill acquisition in the formation of archaeological assemblages. Perhaps even more often they conflate the terms “novice” and “child” in ways that oversimplify the factors that are involved in incorporating new producers into craft production. In particular, the skill acquisition involved in stone tool production is influenced by a variety of factors, including danger, raw material value, raw material availability, and raw material recyclability, as well as a variety of social factors. This paper examines the influence of each of these factors and also suggests patterns useful in recognizing and distinguishing between novices and children in the archaeological record.

Blank Concerns: Issues of Skill and Consistency in the Replication of Scottish Later Mesolithic Blades

Skill is central to the identification of the individual within lithic analysis. Modern replication tends to focus on the proficient flintknapper, and emphasises complex, technically demanding implements and high quality raw materials. Yet, acquiring lithic skill is a universal process that manifests itself in various ways depending on technological strategy and raw material. This paper presents the results of a programme of experimental replication that explores notions of consistency and identity. Based on Mesolithic blade technology, using direct percussion reduction and variable pebble resources, it compares knappers with different experience and identifies some salient parameters of individual performance.     

Oldowan behavior and raw material transport: perspectives from the Kanjera Formation

The archaeological record of Oldowan hominins represents a diverse behavioral system. It has been suggested that exploitation of lithic resources by Oldowan hominins was simplistic and represented mostly use of local sources of stone. Here we investigate the raw material selection and transport behaviors of Oldowan hominins reflected in the stone artifact assemblages from the Kanjera South Formation, South Rachuonyo District, Kenya. Using geochemical methods (ED-XRF) artifacts are linked to primary and secondary source outcrops throughout southwestern Kenya. These data show that hominins selected raw materials for transport at frequencies that are significantly different from their availability on ancient landscapes. Furthermore, a substantial proportion of the assemblage represents transport over relatively long distances (>10 km). Our study further suggests that in the early stages of stone tool use hominins used a wide variety of raw materials and selected these materials at some distance from their eventual discard locations. Early hominin behavior may have incorporated an understanding of raw material source distributions across a more extensive landscape than has been previously documented. This supports the growing perspective that Oldowan technology represents a more complex behavioral pattern than is usually associated with the beginnings of hominin tool use.     

Not Just a Jesuit Atlas of China: Qing Imperial Cartography and Its European Connections

In the literature, the ‘Overview Maps of Imperial Territories’ or Huangyu quanlan tu 皇輿全覽圖, is mostly referred to as ‘the Jesuit atlas of China’. The reason is that this early eighteenth-century atlas of all Qing China’s territories plus Korea and Tibet is assumed to have resulted from European missionaries importing European cartographic practices. In this essay, I argue that this view is outdated and can no longer be sustained. By revisiting the background of the missionaries’ involvement in cartographic exchanges between Asia and Europe, the techniques used for surveying Qing territories and the production of the resulting atlases, I show that the mapping project behind the ‘Overview Maps of Imperial Territories’ is best understood as a creative answer to the unique needs of Qing frontier management and imperial control, made possible by the integration, in mensurational and in representational terms, of European and East Asian cartographic practices.
