An Ethnoarchaeological Study on Anthropic Markers from a Shell-midden in Tierra del Fuego (Southern Argentina): Lanashuaia II

ABSTRACT

For many years the identification of activity areas has been carried out through the spatial distribution of lithics, zooarchaeological remains and specific features such as fireplaces. However, these data are rarely combined and integrated with results from specific analytical techniques such as phytoliths, organic matter, carbonates and multielemental analysis. This research presents the first results of an intrasite spatial analysis on a layer from the site Lanashuaia II, a shell-midden located on the Beagle Channel coast (Tierra del Fuego, Argentina). Ethnoarchaeology is used as a methodological tool to give content to the concept of anthropic markers by means of formulating archaeological hypothesis on the basis of ethnological information. This paper presents the application of specific anthropic markers, which have been designed and applied to identify ashy remains and waste areas through different combinations of proxies. The results show how an approach that integrates different techniques enhances data interpretation and allows to give visibility to activities that may not leave visible evidences.     

Designing cultural policy in a postcolonial colony: the case of Puerto Rico

Puerto Rico became a territory of the United States in 1898 with the end of the Spanish-American War. In 1952, the island became a ‘Commonwealth’ through the development and approval of a local constitution. While this political status allows Puerto Rico some degree of autonomy, it nevertheless continues to subject the island to United States federal authority. For the last 60 years, discussions on whether Puerto Rico’s Commonwealth status is a permanent or transitional status has fuelled much of the political debate and public policy of the region, and has been highly influenced by political status ideologies: to become a state of the United States, to maintain the current status, or to become independendent. Budgetary, legal, and commercial dependence on the United States causes constant conflicts in the design and implementation of Puerto Rican public policy in areas such as education, law, and economic development. Likewise, culture has not been exempt from these debates. In fact, cultural differences have caused conflict at all levels – from the theoretical conceptions of culture, to cultural policy and arts management. Moreover, the implementation of cultural policies has also been subject to political ideologies and the concept of culture has variably been seen as an obstacle or strength for specific political purposes. In the midst of a sustained economic crisis, the current Puerto Rican government has proposed the development of a comprehensive cultural policy through a participatory process. The objective of this paper is to present this process as a means of analyzing Puerto Rico’s experience through the challenges in designing and implementing cultural policy within a ‘postcolonial colony’ scenario. This paper will place emphasis on the government’s role, cultural public institutions, and cultural production.     

We will be known by the tracks we leave behind: Exotic lithic raw materials,mobility and social networking among the Côa Valley foragers (Portugal)

The aim of this study is to establish different socio-cultural models based on lithic raw material sourcing integrated with regional rock art distributions to infer social behaviours within the context of central Iberian Upper Palaeolithic societies. Specifically, we focus on Upper Palaeolithic hunter–gatherer mobility and social interaction in the Côa Valley. This study relies on a knowledge of regional geology and field work to identify the sources of the lithic raw material found at Côa Valley Upper Palaeolithic sites. We expose the context of use and discard of flint, which is naturally absent from the region, and other local materials. From this, we present a GIS based analysis concerning space, time and least-cost paths travelled. This analysis, along with the environmental data available, forms a baseline to evaluate different anthropological models on hunter–gatherer lithic use, mobility, and social networks. We conclude with a three-level model for social interaction, in the context of aggregation activities between different social meta-groups, which involves embedded procurement, long-distance raw material exchange, and symbolic community, reflected in the largest known open-air Upper Palaeolithic rock art concentration.     

Tempus Fugit,Incumbency Stays: Measuring the Incumbency Advantage in the U.S. Senate

This article evaluates the incumbency advantage in the U.S. Senate. We argue that existing methods utilized to measure this advantage are suboptimal to gauge the concept in the Senate. After testing and highlighting the weaknesses of some of these methods, we present an alternative way to measure the incumbency advantage based on the number of electoral victories or terms spent in office. We test the impact of this new measure on candidates’ reelection prospects and their vote share by analyzing senatorial elections from 1948 to 2008. We find that the share of the vote obtained by incumbents increases linearly with time spend in office.     

Measuring Regional Cohesion Effects of Large-scale Transport Infrastructure Investments: An Accessibility Approach

Transport infrastructure is considered one of the main policy instruments to achieve the cohesion goal, although the inclusion of cohesion effects in assessment methodologies is scarce and uneven. Although most cohesion studies are constrained to the analysis of regional disparities in economic indicators, this approach can be broadened to include other regional performance indicators. One of these indicators could be accessibility measures, from the point of view that accessibility, representing a competitive advantage of locations, constitutes a “desirable good” closely related to the welfare of each region. This paper suggests using changes in the spatial distribution of accessibility as a proxy to assess regional cohesion effects of transport infrastructure investments. However, as the conclusions taken depend heavily on the formulation of the accessibility measure, we recommend computing a set of accessibility indicators and analysing their results in a complementary way. The proposed methodology is tested by assessing regional cohesion effects of the large-scale road and rail transport infrastructure investments carried out in Spain in the period 1992–2004. The results obtained show that cohesion has improved for the road mode, while regional disparities have increased for the rail mode. This paper identifies the main factors driving this final cohesion effect and explores the strengths and weaknesses of the different accessibility indicators that were considered. The approach suggested in this paper has the potential to be applied in transport planning processes, and may eventually complement existing strategic assessment methodologies.     

Flint and Quartzite: Distinguishing Raw Material Through Bone Cut Marks

Since the 1980s, several experimental analyses have been able to differentiate some lithic tool types and some of their raw materials according to the morphology of cut marks imprinted by such tools when used for butchering activities. Thus, metal tool use has been differentiated in contexts with an abundance of lithic tools, or even the use of hand axes has been documented in carcass processing, in contrast with simple unretouched or retouched flakes. As important as this information is, there are still other important aspects to be analysed. Can cut marks produced with different lithic raw material types be differentiated? Can cut marks made with different types of the same raw material type be characterized and differentiated? The objective of this study is to evaluate if cut marks resulting from the use of different flints and different quartzites are distinguishable from each other. In the present work, an experimental analysis of hundreds of cut marks produced by five types of flint and five varieties of quartzite was carried out. Microphotogrammetry and geometric–morphometric techniques were applied to analyse these cut marks. The results show that flint cut marks and quartzite cut marks can be characterized at the assemblage level. Different types of flint produced cut marks that were not significantly different from each other. Cut marks made with Olduvai Gorge quartzite were significantly different from those produced with a set comprising several other types of quartzites. Crystal size, which is larger in Olduvai Gorge quartzites (0.5 mm) than Spanish quartzites (177–250 μm), is discussed as being the main reason for these statistically significant differences. This documented intra‐sample and inter‐sample variance does not hinder the resolution of the approach to differentiate between these two generic raw material types and opens the door for the application of this method in archaeological contexts.
