Pits and pitfalls: taxonomic variability and patterning in tooth mark dimensions

Archaeologists use experimentally derived tooth mark frequencies, locations, and size data to infer (a) the extent of carnivore involvement in the formation and modification of faunal assemblages, (b) the size classes of predators marking those assemblages, and (c) whether hominins accessed fleshy or defleshed carcasses (Blumenschine and Pobiner, 2007; Dominguez-Rodrigo et al., 2007). These inferences are often debated in part because frequency counts can vary widely among observers and because the carnivore taxa for which tooth mark dimensional data are available are limited. This study contributes to the body of actualistic/experimental tooth mark data and presents a methodology for collecting these data. We offer a greatly simplified method that may encourage others to collect and quantify tooth mark dimensions. We present dimensional data from feeding experiments with 16 omnivore and carnivore species of known age and mass, ranging in size from skunks to tigers, significantly expanding the taxonomic and size range of carnivores for which we have tooth pit data. Our results demonstrate considerable, but not complete, overlap in tooth pit dimensions among size, class, and taxon. Tooth mark dimensions on epiphyses and metaphyses were relatively strongly correlated with body mass, whereas diaphyseal tooth marks exhibited the weakest correlation. Human consumption of animal tissue produced tooth marks comparable in size to medium felids and small canids, suggesting the possibility that some tooth marks on Early Stone Age (ESA) faunal assemblages could, as suggested by Oliver (1994), result from small carnivore and/or hominin consumption.     

Boathouses in Northern Europe and the North Atlantic

The paper describes the status and further perspectives of boathouse research in Northern Europe and the North Atlantic. The main questions asked are: what are the characteristics of such buildings in archaeological, social and functional terms, and which options are given to promote further research? The case of Norway, where there is a continuing tradition of storing boats in boathouses, plays a key role. The Norwegian experiences seem to be to some extent transferable to other areas in the Northern Europe and the North Atlantic. © 2005 The Nautical Archaeology Society     

Boundary mechanisms and symbolic resources: towards a process‐oriented approach to national identity*

This article argues that the classical distinction between civic and ethnic forms of national identity has proved too schematic to come to terms with the dynamic nature of social and political processes. This has caused difficulties particularly for those historians and social scientists studying particular national movements rather than concentrating on a handful of thinkers and intellectuals or taking a broadly comparative approach. As an alternative to the classical model, I propose to distinguish between, on the one hand, the mechanisms which social actors use as they reconstruct the boundaries of national identity at a particular point in time; and, on the other, the symbolic resources upon which they draw when they reconstruct these boundaries.     

HISTORICAL PRESERVATION AND IDENTITY: THE ALAMO AND THE PRODUCTION OF A CONSUMER LANDSCAPE

Historical preservation often reveals more about contemporary culture than about history. The Alamo in San Antonio, Texas, is just such a case. No other large US city is so dominated by a single historical event, and the Alamo plays a central role as a cultural icon for regional Anglo identity, a symbol of the Anglo-dominated social hierarchy. Its preservation and restoration have coincided with modern identity formation contextualized by commodities. Thus, a critical part of this project is the development of a consumer landscape as an economic extension of the Alamo that promotes consumption by harmonizing with prevailing Anglo conceptions of ethnic identities; not simply a strategically located commercial zone, but an integral part of the pilgrimage to the monument, providing a mechanism for socialization, including "racialization", contextualized by commodities.     

Kriging the Local Risk of a Rare Disease from a Register of Diagnoses

A substantial problem in studying the geographical epidemiology of rare noncontagious diseases is to estimate the risks of their development within populations. A geostatistical solution is described and illustrated by a case study of cancer among children in the West Midlands of England for the years 1980 to 1984 inclusive. Data consist of the numbers of diagnosed cases of cancer and of healthy children in each of 838 electoral wards, the centroids of which are known accurately. The rate of incidence or frequency, equal to the number of cases divided by the number of children, is a binomial variable and is treated as a realization of the underlying risk of a child's developing the disease that varies from place to place. The experimental variogram of the frequency was computed using the standard formulation. The variogram of the risk was obtained from it taking into account the numbers of children at risk and the error associated with each observed frequency. The variogram of the risk increased monotonically from 0 at zero lag to about 50 kilometers, and it was modeled as Whittle's two-dimensional elementary correlation function. The covariances of frequency and cross-covariances between the frequency and the risk were derived from it, and these were then used together with the data to krige the risk and map it. The risk of developing the disease is shown to have a patchy distribution, strongly autocorrelated at the regional scale of the investigation.     

Incorporating “virtual” and “real world” field trips into introductory geography modules

The “field trip” is a key pedagogical tool within geographical education to encourage deep learning, though they are increasingly difficult to implement due to reduced budgets, safety concerns and increasing class sizes. We incorporated three field-learning activities into a large introductory module. A traditional staff-led trip was the most effective activity in terms of enjoyment, knowledge, and deep thinking and awareness. Self-paced field activities and video podcasts had less pedagogical value, though can still support lectures and the staff-led field trip. An integrated approach will best maximize deep learning opportunities.
