WORKINGS OF THE MELTING POT: SOCIAL NETWORKS AND THE EVOLUTION OF POPULATION ATTRIBUTES*

ABSTRACT This paper links the two nascent economic literatures on social networks and cultural assimilation by investigating the evolution of population attributes in a simple model where agents are influenced by their acquaintances. The main conclusion of the analysis is that attributes converge to a melting‐pot equilibrium, where everyone is identical, provided the social network exhibits a sufficient degree of interconnectedness. When the model is extended to allow an expanding acquaintance set, convergence is guaranteed provided a weaker interconnectedness condition is satisfied, and convergence is rapid. If the intensity of interactions with acquaintances becomes endogenous, convergence (when it occurs) is slowed when agents prefer to interact with people like themselves and hastened when interaction with dissimilar agents is preferred.     

Evaluating the Potential of Semi-Automated Image Analysis for Delimiting Soil and Sediment Layers

ABSTRACT

Established methods for delineating anthropogenic and natural strata during fieldwork are based on the visual and tactile perception of excavators. Modern image analysis techniques can help to ensure objectivity and reproducibility when documenting sections and plana. Within this study we examine the unsupervised classification of digital images as a technique for delimiting layers and identifying stratigraphic features. Assessing the potential of this approach, we exemplarily captured soil profiles with high-contrast stratigraphy, located in the area of a historical vineyard (Brandenburg, Germany). Reproducible analyses were carried out using open-source software, allowing for the future advancement of the methodology utilized and providing a basis for the analysis of more complex stratigraphic sequences. We compare clustering results of high-resolution RGB and hyperspectral images (470–830?nm, 37 bands). Multiple pre-processing and processing steps are carried out to evaluate their influence. Our results render the semi-automatic analysis of RGB images helpful for stratigraphic interpretation.

‘Old wood’ effect in radiocarbon dating of prehistoric cremated bones?

Numerous reports of successful radiocarbon dating of cremated bones have emerged during the last decade. The success of radiocarbon dating cremated bones depends on the temperature during burning and the degree of recrystallisation of the inorganic bone matrix. During cremation bones undergo major morphological and mineralogical changes which have raised some interesting questions and discussion on the origin of the carbon source in archaeologically cremated bones. Recent laboratory experiments reveal that the properties of the combustion atmosphere play a significant role regarding the source carbon in cremated bones. Thus radiocarbon dating cremated bones is potentially dating the wood used for the cremation fire. Here we compare a high precision radiocarbon dated human bone with an associated dendrochronological age from an oak coffin. We find that the age discrepancy between the dendrochronological age and the cremated bone of 73 ± 26 ¹⁴C yr is best accounted for by the so called ‘old wood’ effect.     

Faecal biomarker and archaeobotanical analyses of sediments from a public latrine shed new light on ruralisation in Sagalassos, Turkey

A public latrine in the ‘Imperial Baths’ of Sagalassos was transformed into a dump site in the early Byzantine period. Several layers of urban waste, including ceramics, bones, glass and perhaps excrements were deposited on the floor. Faecal biomarker analyses and archaeobotanical analyses were conducted to reconstruct the history of the room. 5β-stanols of human origin, such as coprostanol, were found in the sewage channels together with mineralised plant remains, indicating a human faecal context. The botanical remains are furthermore representative of the Roman diet of the Sagalassians. Soil layers, deposited on top of the latrine floor and dating to the early Byzantine period, contained herbivore derived 5β-stanols, such as 5β-stigmastanol and epi-5β-stigmastanol. Additionally, a clear predominance of epi-5β-stanols over 5β-stanols showed that the animal dung has been subject to composting. In this period, the former latrine was clearly used as a manure production site which is further confirmed by stratigraphic evidence of large amounts of urban waste artefacts, which were commonly collected together with manure before application on the fields. The results of the present study support the theory that off-site potsherd scattering can be used as a proxy for manuring events. Additionally, the data show key evidence for vertical migration of 5β-stanols and presumably also for the leaching of bile acids.     

Multiple multiculturalisms: insights from the Edinburgh Mela

This paper contributes to debates about the future of multiculturalism in Britain by exploring how it is conceptualized, constructed and experienced in contemporary Scotland. The work is grounded in Hall's (2000) important but commonly overlooked distinction between a ‘multicultural society’, which designates a condition of cultural diversity, and ‘multiculturalism’, which refers to processes and policies that attempt to fix the meaning of such diversity. As these definitions suggest, the abandonment of multiculturalism as a ‘policy failure’ cannot be a solution to problems arising from the complex composition of contemporary societies. The fact that all societies must make decisions about the significance of cultural diversity and its management—they must all practise some form of multiculturalism—is established through a review of how multiculturalism has been conceptualized and pursued to date. The paper then draws on the example of Edinburgh's South Asian Festival—the Mela—to explore the empirical complexities of these different applications in a Scottish context. An analysis of the Mela's changing organization and artistic programme over time reveals the coexistence of multiple conceptions of multiculturalism—in time, space and experience. This progressive reinterpretation of multiculturalism—as multiple—advances the goals of both cultural diversity and societal cohesiveness.     

The structure of the pomor settlement complex on the Schønningholmane site (Hornsund,West Spitsbergen) archaeological data

This article is an attempt to develop a discussion within the archaeological world, with reference to a particular aspect of Russian hunting on Svalbard.

In general, such a discussion is vital, because the written sources concerning the Russian activity on Svalbard are rather weak (as is frequently the case with areas on the periphery of cultural centers).

Archaeology must therefore play an important role in the reconstruction of the archipelago's cultural history, even as recently as the 17th ‐19th centuries.
