Ceramic diversity,random copying,and tests for selectivity in ceramic production

This paper examines the evidence for selective reproduction of ceramic types based on their evolving frequency distribution, and on correlations of the abundance of types with underlying functional characteristics. How can we tell if a variant has been preferentially selected or discriminated against, and become more or less frequent than would be expected under pure drift (i.e. random copying, with the compounding over time of proportionate sampling error)? We examined a database of Hittite ceramic bowl types from two successive Phases of occupation of the Upper City of Bo?azköy–Hattusa, capital of the Hittite empire and the largest Bronze Age settlement in Turkey. We applied two tests used in genetics to assess departures from neutrality, to assess selectivity in rates of reproduction of ceramic bowl types (the Ewens-Watterson and Slatkin's Exact tests). We also examined the effects of ceramic fabric and vessel dimensions on changes in vessel abundance between the two Phases, using regression analysis. We found that while the frequency distribution of rim sherds did not in itself enable us to reject the null hypothesis of random copying, closer examination of the characteristics of these types enabled us to recognize latent dimensions of functional variability (including ware type and bowl diameter) that had demonstrably been the subject of selective decision-making by the potters. The present case study suggests that we should be wary of applying the neutral model from genetics uncritically in archaeology, because it is much harder to prove that the cultural traits whose frequencies are being modelled are genuinely functionally equivalent (as that model requires).     

Terrestrial laser scanning intensity data applied to damage detection for historical buildings

This paper presents a methodology to combine the technology of the terrestrial laser scanner with the techniques of digital image processing in order to study damages on stony materials that constitute historical buildings. This methodology has been tested using intensity data from three terrestrial laser scanners with different technical specifications. The unsupervised classification algorithms were used for the classification of 2D intensity images derived from the 3D information obtained from laser scanner equipment. The results obtained show the potential of the use of intensity data from terrestrial laser scanner for the recognition and characterization of certain pathologies in building materials that constitute historical buildings.     

Detecting the effects of selection and stochastic forces in archaeological assemblages

Detecting and diagnosing the causes of change through time in archaeological assemblages is a core enterprise of archaeology. Evolutionary approaches to this problem typically cast the causes of culture change as being either stochastic in origin, or arising from selection. Stochastic sources of change include random innovations, copying errors, drift and founder effects among dispersing groups. Selection is driven by differences in payoffs between cultural variants. Most efforts to identify these evolutionary forces in the archaeological record have relied on assessing how well the predictions from a neutral-stochastic model of cultural transmission fit a data set. Selection is inferred when the neutral-stochastic model fits poorly. A problem with this approach is that it does not test directly for the presence selection. Moreover, it does not account for the fact that both neutral-stochastic and selective forces can act at the same time on the same cultural variants. A different approach based on the Price Equation allows for the simultaneous measurement of selective and stochastic forces. This paper extends use of the Price Equation to the analysis of selective and stochastic forces operating on multiple artifact types within an assemblage. Ceramic data presented by Steele et al. (2010, Vol. 37(6): 1348–1358) from the Late Bronze Age Hittite site of Bo?azköy-Hattusa, Turkey, provide an opportunity to evaluate the efficacy of this model. The results suggest that selection is a dominant process driving the frequency evolution of different bowl rim types within the assemblage and that stochastic forces played little or no role. It is also clear, however, that we should be attentive to combinations of direct and indirect selective effects within assemblages consisting of multiple artifact types.

毕节青场瓦窑商周遗址发掘主要收获

青场瓦窑遗址是贵州商周时期非常重要的一处古文化遗址。2008年10月至12月对其进行了第二次发掘,清理出更加丰富的遗迹,出土大量陶石器等遗物,对其文化特征和发展演变有了突破性认识。出土资料表明,它与分布在乌蒙山西缘的鸡公山文化遗存有一定联系但是独立发展的两个文化系统,原因与地理阻隔有关,瓦窑遗址在发展中更多地受到来自其北部四川盆地商周时期古文化的影响。

Brazilian cultural policies during the workers’ party governments: challenges for the development of cultural citizenship

ABSTRACT

The presidential elections that brought the Workers’ Party (Partido dos Trabalhadores, or PT) to federal power represented a new moment for Brazil with the implementation of democratic, inclusive and sovereign policies. In the area of culture, the Ministry of Culture reclaimed a leadership role for the State and developed public policies with the critical participation of civil society. During the administrations of presidents Luis Inácio Lula da Silva and Dilma Rousseff, culture finally reached a new level. This article seeks to determine to what extent the cultural policies undertaken by these administrations promoted cultural citizenship. Based on a study of the course of cultural policies in the country, we argue that despite a conceptual and ideological orientation in this direction, the Ministry was unable to surpass certain barriers and overcome longstanding problems.     

Power,Culture, and the Rise of Transnational History in the United States

This essay focuses on the impact of the cultural turn on the writing of international history in the United States. It argues that the cultural turn has significantly shaped the emergence and practice of transnational history in the United States, drawing foreign relations history closer to other fields within American history and distancing it from the way transnational history is practiced elsewhere, particularly in Europe. It has created a more vibrant and much less well-defined field that engages with issues of race, gender, decolonization, human rights, and the environment. At first glance, the trajectory from the cultural to the transnational turn is not necessarily an obvious one. Both represent distinct approaches with distinct methodologies, historical questions, and subjects. Nonetheless, their fusion in the United States has set the American approach to transnational history apart from its European and non-western counterparts.     

A political geography of walking in Jordan: Movement and politics

The past 10-15 years has seen the growth of walking groups taking walkers from Amman to rural parts of Jordan at weekends and the development of the Jordan Trail. Through the narration and analysis of everyday accounts of walking, this paper explores political geographies of identity, movement, and territory in Jordan. Drawing on 12 months of ethnographic fieldwork, I suggest that at the heart of a growth of walking for leisure in Jordan are important political questions. How is walking conditioned by situated cultural politics? How can walking unearth intimate and embodied accounts of territory in Jordan? I build upon three developments in political geography to do this. First, research on political geography and walking; second research on everyday political geographies of the Middle East; third, critical and feminist work on territory. Literature on political geography and walking is developed by centring Jordanian walkers and the (post)colonial context of Jordan to explore what walking means under different political conditions and for individual bodies. In doing so I contribute to work on identity and nationalism in Jordan and the importance of the everyday to explore political geographies of the Middle East. I develop critical and feminist work on territory by arguing that walking bodies make and contest territory and in doing so calling for greater synergies between cultural and political geography. These arguments are made in two empirical sections. The first explores how different people talk about walking, the language for walking, and assumptions about walking bodies. The second explores how walking connects different bodies to territory, and creates territorial nationalist narratives, but also how walking can highlight indigenous and embodied relations with territory. This paper concludes that walking is political because it shapes and is shaped by situated political geographies and because it enables embodied and intimate accounts of territory to emerge.     

Migrant workers,self‐reliance,and the propensity to hold income protection insurance by country of residence

Utilising a large comparative survey across 11 countries, it is shown that country effects condition the individual uptake of income protection insurance and that shared attributes, including labour market status, are important factors in determining the take‐up of income protection insurance, whatever the respondents' country of residence. We observed differences in the respondents' coping strategies, including self‐reliance, and were able to distinguish between migrant workers and those who work in their country of origin, along with the “special” case of the Australian respondents. These findings have implications for the ongoing debate on the labour market effects of globalisation and the significance of national institutions and regulatory practices.
