Inclusion in an Archaeological Project: Trouvadore Project. A Case Study

Is it the role of archaeologists to lead on community involvement? In 2000 the Trouvadore Project was launched as a partnership. The archaeologists of Ships of Discovery were to search for the shipwreck, film makers Windward Media were to document the project and the Turks and Caicos National Museum was to research the wrecking and the legacy of the survivors. With its developing outreach programmes it was natural for the museum to take on the responsibility of informing and involving the community in the project. This is the story of community inclusion in the search for the slave ship Troubadour.     

Casting the Riace Bronzes: Modern Assumptions and Ancient Facts

This article argues that classical archaeologists have seriously underestimated the output of heat required to melt a large quantity of bronze and therefore have wrongly reconstructed the ancient casting process. The idea that sufficient metal for casting a bronze of monumental proportions could be heated in a crucible with a charcoal fire ventilated by bellows is not realistic. The following observations are based on solid foundry experience: Nigel Konstam, a bronze sculptor, for many years supervised the casting of monumental bronzes comparable in size to those from Riace. This article has been written by Herbert Hoffmann drawing on Konstam's notes     

Consumption,exclusion and emotion: The social geographies of shopping

In recent years, a productive dialogue has developed between retail geographers and those social geographers concerned with the spatiality of consumption. This has resulted in a series of accounts of shopping that emphasize notions of consumer creativity. Nonetheless, this paper argues that many of these have struggled to reconcile the meaning of shopping with an understanding of the material parameters within which consumers operate. Recognizing that this tendency has distracted from the socio-spatial inequalities evident in retailing, the paper examines how shopping rituals are embedded in social relations that discourage particular shoppers from visiting certain retail locations. Drawing on extensive and intensive data derived in Coventry (UK), the paper questions the extent to which this geography of exclusion is the product of constraint, arguing that shopping is shaped by a more complex spatiality of inclusion and (self-) exclusion. Accordingly, the paper makes the case for a social geography of shopping that pays careful attention to the emotionally laden transactions played out in particular settings.     

Permeability of the Mercia Mudstone: suitability as caprock to carbon capture and storage sites

The Upper Triassic Mercia Mudstone is the caprock to potential carbon capture and storage (CCS) sites in porous and permeable Lower Triassic Sherwood Sandstone reservoirs and aquifers in the UK (primarily offshore). This study presents direct measurements of vertical (k_v) and horizontal (k_h) permeability of core samples from the Mercia Mudstone across a range of effective stress conditions to test their caprock quality and to assess how they will respond to changing effective stress conditions that may occur during CO₂ injection and storage. The Mercia samples analysed were either clay‐rich (muddy) siltstones or relatively clean siltstones cemented by carbonate and gypsum. Porosity is fairly uniform (between 7.4 and 10.7%). Porosity is low either due to abundant depositional illite or abundant diagenetic carbonate and gypsum cements. Permeability values are as low as 10^?20 m² (10nD), and therefore, the Mercia has high sealing capacity. These rocks have similar horizontal and vertical permeabilities with the highest k_h/k_v ratio of 2.03 but an upscaled k_h/k_v ratio is 39, using the arithmetic mean of k_h and the harmonic mean of k_v. Permeability is inversely related to the illite clay content; the most clay‐rich (illite‐rich) samples represent very good caprock quality; the cleaner Mercia Mudstone samples, with pore‐filling carbonate and gypsum cements, represent fair to good caprock quality. Pressure sensitivity of permeability increases with increasing clay mineral content. As pore pressure increases during CO₂ injection, the permeability of the most clay‐rich rocks will increase more than carbonate‐ and gypsum‐rich rocks, thus decreasing permeability heterogeneity. The best quality Mercia Mudstone caprock is probably not geochemically sensitive to CO₂ injection as illite, the cause of the lowest permeability, is relatively stable in the presence of CO₂–water mixtures.     

People and Things on the Move: Domestic Material Culture,Poverty and Mobility in Victorian London

The development of what Mayne and Lawrence (Urban History 26: 325–48, 1999) termed “ethnographic” approaches to studying nineteenth-century households and urban communities has gathered momentum in recent years. As such research agendas have taken hold and been applied to new contexts, so critiques, methodological developments, and new intellectual and theoretical currents, have provided opportunities to enhance and develop approaches. This article contributes to this on-going process. Drawing upon household archaeological research on Limehouse, a poor neighborhood in Victorian London, and inspired by the theoretical insights provided by the “new mobilities paradigm,” it aims to place “mobility” as a central and enabling intellectual framework for understanding the relationships between people, place, and poverty. Poor communities in nineteenth-century cities were undeniably mobile and transient. Historians and archaeologists have often regarded this mobility as an obstacle to studying everyday life in such contexts. However, examining temporal routines and geographical movements across a variety of time frames and geographical scales, this article argues that mobility is actually key to understanding urban life and an important mechanism for interpreting the fragmented material and documentary traces left by poor households in the nineteenth-century metropolis.     

Discrete Element Modeling of Stone Masonry Walls With Varying Core Conditions: Prince of Wales Fort Case Study

The Prince of Wales Fort was constructed in the 18th century as a Vauban style stone masonry fortification where the Churchill River flows into Hudson’s Bay, across the river from Churchill, Manitoba, Canada. Since completion the fort has been exposed to harsh weather conditions, which have led to significant deterioration and deformations in the walls, with some cases of localized collapse. Recently, an increase in the rate of degradation has made preventative conservation an issue of interest. For this conservation to be possible, an understanding of the cause of failure of the walls is first required. Discrete element modeling (DEM) using the non-smooth contact dynamics (NSCD) method utilized in the Program LMGC90 has been used as a first step in understanding the failure mechanism of the wall system. The results of the modeling show that the rubble core of the walls can transition from stability to instability as the cohesion between the stones is altered. Grouting the core will alter the bond between stones, increasing the stability of the core, and is thus one possible conservation method.     

CD ROM imaging in osteoarchaeology

This paper describes the potential use of CD ROM in osteoarchaeology. It describes what CD ROM is and how it works, how CD ROM disks are produced and how the technique could be used in osteoarchaeology. The hardware required, both to produce and access compact disks, is outlined together with approximate costs. The possible uses of the technique in osteoarchaeology are suggested. Costs for the hardware are reasonable. However, collaboration between organizations will be essential.     

Constructing a Manufacturing Fixed Capital Stock Series for the Regions of Greece

Although regional variation in rates of capital accumulation is considered a major component of spatially uneven industrial development, it remains largely an understudied area. The theoretical and methodological problems that surround the measurement of capital, generally, alongside the lack of necessary information about a wide range of specific aspects, pose serious obstacles in any attempt to construct regional capital stock series. In such a context, the main aim of this paper is to make the best possible effort to construct a regional manufacturing fixed capital stock series for Greece. The limited availability of information (not unusual in regional as opposed to national contexts) and the necessity of making some arbitrary, but specified, assumptions mean that the estimation steps have to be presented in detail to assess reliability. Four regional fixed capital stock series for total manufacturing activity are generated. The results are then assessed in the context of uneven spatial development in Greece.
