Long-distance provenance for obsidian artifacts of Mesoamerica Preclassic and Early Classic periods found in the Los Naranjos Archaeological Park (Honduras)

Los Naranjos is one of the most important pre-Columbian human settlements of Honduras related to the south-easternmost border of the Mayan civilization. Although the archaeological site mostly spans from 850 BC to 1250 AD, the present obsidian study was only focused on the Preclassic and Early Classic periods (Jaral, 800–400 BC and Edén, 400 BC–550 AD) where undamaged blades and/or retouched obsidian flakes are rare. In this way, the INAA analyses of 17 obsidian samples, compared with major-trace elements data of Honduran and Guatemalan obsidian sources, are mostly representative of waste flakes. Lithic artifacts of Los Naranjos such as sandstones, basalts, and quartzites come from local geological outcrops; whereas, obsidian provenance has to be searched from sources which are located within a radius up to 300 km far away. San Luis, La Esperanza, and Güinope obsidian sources are located in Honduras while the three most exploited Highland Guatemalan obsidian outcrops, which have been dominating long-distance trade in the Maya area mostly for the Classic-Postclassic periods, are San Martin de Jilotepeque, El Chayal, and Ixtepeque. An Ixtepeque provenance, for all the investigated obsidian samples of Preclassic and Early Classic periods found in the Los Naranjos Archaeological Park, was established, thus emphasizing a long-distance source (180 km). This also confirms that Ixtepeque represents the most important provenance of the obsidian artifacts found in archaeological sites of Western and Central-Western Honduras. The possible role played by some of the most important rivers of Guatemala and Honduras as waterway networks of transport was finally pointed out. New INAA chemical data from the Honduran obsidian source of La Esperanza (“Los Hoyos”, 4 samples) are also reported in this paper.     

Jobs,crime, proximity and boats: explaining Australian public attitudes to immigrant numbers

Despite the importance of immigration to Australia, there is little systematic research on the causes of support among Australian citizens for increased, stable or decreased immigration. This paper advances our understanding of Australian public attitudes to immigration levels in the light of the established international literature on public opinion and immigration. Using 2013 Australian Electoral Study (AES) data, we show that, as in other countries, Australian citizens’ attitudes to immigrant numbers are partly driven by a combination of sociotropic economic considerations and perceptions of the socio-cultural impact of immigrants. In addition, we argue that political mobilisation has an impact on attitudes toward immigration that has not received sufficient attention. We demonstrate that citizens who accepted the Coalition's rhetoric on asylum seeker arrivals were more likely to want overall immigrant numbers reduced. Finally, we combine the individual level AES data with electoral district level data to test the impact of contact with immigrants on attitudes to immigrant numbers. Australians living in electoral districts with higher percentages of non-white immigrants are more likely to want lower immigrant numbers than those living in districts with fewer non-white immigrants.     

Archaeological applications of polynomial texture mapping: analysis,conservation and representation

Polynomial Texture Mapping is an image capture and processing technique that was developed by HP Labs in 2000. It enables the recording and representation of subtle surface details using a standard digital camera and lighting, and software that is free for non-commercial use. Cultural heritage applications have been associated with the technology from its earliest stages, including examples in areas such as cuneiform, numismatics, rock art, lithics and Byzantine art. The paper begins by outlining the technical principles involved. It then brings together the extant work in the field. Through examples developed by the University of Southampton in partnership with a range of UK and international bodies it demonstrates the benefits of the technology in the areas of archaeological analysis, conservation and representation. Finally it considers the future possibilities of this technology and ongoing developments.

City as province in China: the territorial urbanization of Chongqing

Chongqing is a province-level city region in China’s interior with a land area larger than many small countries. Limited scholarship tends to treat Chongqing as a new jurisdiction formed in relation to development of the Three Gorges Dam and reform of historic state-planned industry from the Mao era. This analysis turns to the complex process of land redistricting in a process of “territorial urbanization” that has also simultaneously reshaped the economy of Chongqing. By conceptualizing Chongqing as a dynamic administrative territory, this analysis defines changes in the relational configuration of its administrative divisions (xingzheng quhua) as a multi-faceted state strategy of governing land use change and the fiscal regime to realize infrastructure development. Especially by establishing districts in Chongqing, territorial urbanization works to enhance the funding capacity of the Chongqing government to develop larger, expansive infrastructure projects. This urban transformation of Chongqing demonstrates how processes of land use change and government funding, materializing in the built environment, are directly related to changes in state territorial configuration.
