The Seaweed FlyThoracochaeta zosterae(Hal.) (Diptera: Sphaerocidae) in Inland Archaeological Contexts: δC and δN Solves the Puzzle

The presence of the flyThoracochaeta zosteraein cesspits had led to the unlikely interpretation that seaweed had been present in Mediaeval cesspitis. Archaeological and modern pupae fromT. zosteraewere sampled along with their probable larval diets (extracted plant material from cesspit and seaweed, respectively). The spacing between pupae and food for δ¹³C and δ¹⁵N was similar for both modern and archaeological samples. Modern pupae had isotopic ratios typical for marine invertebrates for δ¹³C. Archaeological puparia had isotopic values typical for terrestrial grazers (i.e., non-marine), indicating that there was no marine inclusion in the cesspits.     

Prehistoric Shellfish Exploitation in Coastal New York

Abstract

Sectioning studies of marine bivalves are broadening our understanding of prehistoric shellfish exploitation along the Atlantic coast of North America. We review the evidence for the timing of shellfish exploitation in coastal New York and present the results of a recent sectioning study of Mercenaria mercenaria from the Sungic Midden site on Shelter Island, New York. The results compare favorably with the harvesting patterns of other north Atlantic Sites, indicating that shellfish exploitation took place during more than one season of the year. The implications of these findings are examined in relation to current subsistence-settlement models of coastal New York.

Implications of gendered environmental knowledge in water allocation processes in central Australia

The existence of gendered knowledge has been identified as a significant feature of Indigenous Australian culture, and the importance of considering the implications of gendered environmental knowledge in collaborative cross-cultural natural resource management has been highlighted. There is a lack of case studies that demonstrate how Indigenous women's knowledge and laws can be provided for in resource management contexts. From collaborative research with Anmatyerr women in central Australia, we discuss the implications of gender bias in relation to gendered knowledge in natural and cultural resource management, with a specific focus on Anmatyerr women's involvement in providing inputs about the cultural values of water within water allocation planning processes. This research highlights Anmatyerr women's own perspectives of their roles in contemporary contexts and identifies the existence of cultural change and continuity in relation to rights and responsibilities around water.     

Lowland Floodplain Responses to Extreme Flood Events: Long-Term Studies and Short-Term Microbial Community Response to Water Environment Impacts

Abstract

Targeted studies of waterlogged burial environments allow researchers to gain holistic insights into the physico-chemical and biological condition of wetlands that have the potential to contain organic remains of both anthropogenic and biogenic origin. Recent research has shown that microbial community diversity and functioning are intimately linked to physical and chemical parameters, such that environmental perturbations may have the potential to enhance the effectiveness of microbial communities in the degradation process. Our studies have shown that, as a consequence of the 2007 floods which impacted upon many British lowland rivers, a rapid microbial response to environmental perturbations can be demonstrated within the wetland deposits being monitored. As such, a quantification of the latent functionality of micro-organisms in a soil profile may be of fundamental importance for our understanding of potential in situ degradation processes; and, as a consequence, the likelihood for the biodegradation of sensitive archaeo-organic remains; a factor which is of primary importance for both ongoing and future mitigation strategies, and attempts at managing the cultural resource of wetlands.

This paper will present a consideration of the effectiveness of a long-term research project in a lowland wetland at Newington, Nottinghamshire, England, studied between 2004 and 2008; and evaluate the efficacy of this study in relation to the significant impacts that occurred as a result of the severe floods in 2007. We conclude that the data generated after the floods necessitated a total re-evaluation of the first approximately two years of environmental monitoring, and that the impacts throughout the sediment profile continued for some time after the initial flood event. These observations potentially have far-reaching implications for future in situ monitoring as disruptions to weather patterns influence the various environmental impacts on the wetland resource.     

Arsenic in Danish and Swedish Mesolithic and Neolithic human bones – diet or diagenesis?

Arsenic has previously been measured in a bone sample of a c. 5-year-old Mesolithic child from Nivaagaard in Denmark yielding an anomalously high value of 13 μg/g. In the present work we show that other individuals at a nearby site also exhibit elevated arsenic levels, whereas individuals from other Mesolithic sites in Denmark are found to have quite low As-concentrations. Several attempts to reveal the source of the arsenic are reported: A railway track near the site, where the railway sleepers were suspected to have been impregnated with As leading to transport or diffusion of As into the adjacent soil; Several food items, the remains of which were found at the site, and one food item not preserved in the excavation, i.e. seaweed. Finally, it is shown that the most likely explanation of the elevated arsenic levels in human bones at Nivaa is diagenesis.     

Geophysical Methods for Wreck‐Site Monitoring: the Rapid Archaeological Site Surveying and Evaluation (RASSE) programme

Rapid advances in geophysical techniques over the past decade have provided the maritime archaeological community with significant opportunities for re‐defining the procedures for wreck‐site mapping, evaluation and monitoring. The techniques which offer most potential for high‐resolution survey are acoustic‐based and include sidescan sonar, swath‐bathymetry sonar and multibeam sonar. These techniques were tested on an artificial test‐site in Plymouth Sound and over the wreck of the Stirling Castle. Results demonstrate that the techniques can provide the maritime archaeologist with the opportunity to rapidly and cost‐effectively map and monitor small, centimetric changes on sites, with the potential for long‐term monitoring and management. © 2009 The Authors     

Analysis of the Size,Shape, and Modeled Age of Common Limpets (Patella vulgata) from Late Norse Middens at Sandwick,Unst, Shetland Islands,UK: Evidence for Anthropogenic and Climatic Impacts

Zooarchaeological faunal remains are commonly examined to investigate harvesting behavior. We determined limpet (Patella vulgata) shell size and shape, and estimated shell age from several middens at the Late Norse Sandwick South Site, Unst, Shetland, UK, whose strata represent distinct occupational phases (Phase 1: AD 1100–1200, Phase 2: AD 1200–1250, Phase 3: AD 1250–1350). Our goal was to determine if the many limpets found there could provide insight into Norse harvesting behavior. Shell length, conicity, and modeled age all declined between Phases 1 and 2, suggesting intensive, size-selective harvesting of limpets and a shift to harvesting lower in the intertidal zone between phases. Length and conicity varied in Phases 2 and 3 and no major changes seem to have occurred over these periods, indicating that harvesting maintained the limpet population at an impacted level throughout the later phases. The conicity decline between Phases 1 and 2 may also have been caused by increased storminess that accompanied the onset of the Little Ice Age. The mean length of modern limpet populations near the Norse site did not differ from the archaeological phases, but did vary among collection years. Limpets were 26% larger in 2015 than in 2012 and 2013, indicating that large interannual variations in population structure can occur over short time periods. Potentially the result of extreme storms removing small limpets, this result raises the possibility that size and conicity changes during the Sandwick South Site occupation, as well as in other early populations, could also be the result of environmental factors rather than human harvesting alone. We feel, however, that the most parsimonious explanation for the patterns we document is human harvesting.     

Welfare Theory,Public Goods,and Public Facility Location

The paper discusses a number of issues that are important to the development of a useful normative “welfare theory” of the public space economy. Attention is specifically focused on theoretical welfare economic models of public goods provided at facilities to which consumers must travel for consumption. The recent analysis of Bigman and ReVelle [2] is subjected to critical scrutiny and found wanting. An alternative, more complex but still very simple, analysis is provided.     

A dental microwear study of seaweed‐eating and grazing sheep from Orkney

The potential of dental microwear for recognizing the use of seaweed as fodder in the past is explored through the analysis of microwear patterning in modern seaweed‐eating and grazing sheep from Orkney. Seaweed‐eating and grazing sheep are clearly distinguished on the basis of microscopic dental wear patterns. This reflects an emphasis on anterior‐posterior jaw movements and large pitted features in the seaweed‐eaters and can be attributed to the differing forces and/or masticatory movements required in the comminution of grasses and seaweed. Differences between seaweed‐eating and grazing individuals are maintained when the grazing group is expanded to include grazing sheep from Greenland and the Scottish borders. It is concluded that the microwear of seaweed‐eating sheep is highly distinctive and that dental microwear analysis potentially has a widespread application for identifying seaweed grazing within Scotland and the North Atlantic islands.

Poverty in Transition: An Ethnographic Critique of Household Surveys in Post-Soviet Central Asia

Post-Soviet transitions have prompted a search for new policy tools and methods of data collection. The shift from universal welfare provision under the Soviet system to targeted assistance and poverty monitoring has stimulated a new interest in the measurement of living standards and poverty lines. This has promoted the use of quantitative techniques and sample surveys (household surveys, in particular) as privileged tools for the collection of policy-relevant information. This paper contends that survey techniques have particular limitations as research tools in an environment where local level case studies are scarce and where a host of new socio-economic processes are creating fundamental shifts in the landscape of social provision, redistribution and employment. These limitations are illustrated by drawing upon a household survey conducted by the author in four villages from two regions in Uzbekistan, Andijan and Kashkadarya, between October 1997 and August 1998. The ambiguities surrounding five basic concepts, those of household, employment, access to land, income and expenditure are discussed in detail, as are the changes in their contents and meanings in the context of transition. The gender differentiated outcomes of current changes and their possible implications are highlighted throughout the text. The conclusion suggests that Uzbekistan finds itself at an uneasy juncture where the policies deployed to ‘cushion’ the social costs of transition may reach the limits of their sustainability. A more contextually sensitive approach to the mechanisms that generate new forms of vulnerability and the use of qualitative and longitudinal methodologies are essential to an adequate monitoring of further changes.     

Quantification and Visualization of In Situ Degradation at the World Heritage Site Bryggen in Bergen,Norway

Abstract

Environmental monitoring at the World Heritage Site of Bryggen in Bergen, Norway, has shown damaging settling rates caused by degradation of underlying archaeological deposits. Measurements of piezometric head, oxygen, and soil moisture content, as well as chemical analyses of water and soil samples are key elements of the environmental monitoring.

Groundwater monitoring and geochemical analyses reveal a complex and dynamic flow through the natural and anthropogenic stratigraphy. The preservation conditions within the organic archaeological deposits are strongly correlated with oxygen and soil moisture content, that are controlled by the groundwater flow conditions at the site. To quantify decay rates, it is thus essential to understand the wider hydrogeological context of the site. This paper presents recent advancements in quantifying decay rates in the saturated zone at Bryggen. The paper also shows that 3D geo-archaeological modelling can contribute to preservation management by visually combining results of geological, archaeological, geochemical, and hydrological investigations. This opens up for improved multidisciplinary understanding of preservation potential, thereby contributing to an improved protection of archaeological deposits in situ.     

Growing dens. On re-grounding the child–nature relationship through a new materialist approach to children’s dens

This paper contributes to the dawning disruption of the prevailing notion of the child–nature relationship through a new materialist reading of children’s dens, and proffers a re-grounded and worldly gaze on the relationship with implications for the promotion of children’s outdoor lives. The study is an ethnographical field study among 10–12-year-old boys in a Danish school. Data were generated through participant observation, and include video recordings and photographs of children’s dens. Drawing on a flat ontology and plugging in key Ingoldian concepts of meshwork and growing (Ingold 2011a, 2013), the analysis suggests that children’s relations to dens cut across taken-for-granted subject–object binaries and go beyond common notions of nature as inert materials. I find that dens are growing in an ever-becoming meshwork comprised by human and non-human intra-actions, and that agency or vitality can be ascribed broadly to the material world. Possible implications for planning are considered.     

Shellfish Exploitation in the Western Canary Islands Over the Last Two Millennia

ABSTRACT

The residents of the Canary Archipelago consumed limpets since the arrival of humans ～2500 yrs. ago, and these harvested gastropods were deposited in large coastal shell middens. This work preliminarily explores shell margin oxygen isotope composition (δ¹⁸O) and body size of the black limpet (Patella candei d’Orbigny, 1840) from archaeological sites in the Canary Islands to assess possible seasonal variability and intensity of shellfish collection throughout the late Holocene. The shell margin δ¹⁸O values of 100 shells (radiocarbon dated between ～500 and ～1800 cal. yr BP) were analysed to estimate sea surface temperature (SST) at time of death. Paleotemperature estimates suggest shellfish harvesting was not year-round, and was avoided in the cooler months (when SST?<?20°C). This pattern differs from most higher latitude Mesolithic and Neolithic human groups, which gathered shellfish year-round, targeting winter more heavily. Preliminary body-size measurements suggest shell sizes have experienced a decline from aboriginal times to the present, which possibly resulted from increasing anthropogenic pressures. During aboriginal inhabitation, maximum adult shell size remained stable, suggesting that present-day harvesting practices are more intense than harvesting from aboriginal human groups. This intensive collection has likely diminished the average adult size of limpet populations in the islands by ～27%.     

The reburial of mosaics: an overview of materials and practice

Abstract

A significant proportion of the literature on the reburial of archaeological sites concerns mosaics. These publications reveal that a variety of materials have been used for mosaic reburial, including specialized fill and separation layers, from the early 1980s onwards. Although reburial practice often demonstrates an ad hoc and indiscriminate use of fill and separation materials, or the following of trends and anecdotal information favouring certain materials, knowledge of their characteristics is very important in developing an appropriate technical design for reburial of mosaics. The materials most commonly employed in mosaic reburial practice, including geotextiles, are reviewed and an assessment of their positive and negative characteristics within a reburial design is provided. Recent but limited laboratory and field testing, monitoring and evaluation of reburial interventions have begun to provide preliminary evidence about the behaviour of these materials, indicating which ones are most appropriate and how they should be utilized to best advantage. However, their selection and use remains uneven, and positive results continue to be as much a function of adequate maintenance as proper design and execution.     

Industrial Enterprises and Economic Space: the Network Paradigm

This paper is an extended review essay stimulated by the book of Conti, Malecki and Oinas (1995) on The Industrial Enterprise and its Environment. Three different paradigms of industrial organization are outlined with what has earlier been referred to as the network paradigm best capturing contemporary realities. The spatial implications of this framework are then drawn out and the limits of the paradigm summarized.     

Creation in Art and Science

Abstract

The proposition that the creations of art are unique (in the sense tbat we would not have had Timon of Athens had Shakespeare not lived), whereas the creations of science are inevitable or commonplace (in the sense that we would have had the DNA double helix even if Watson and Crick had not lived), has little philosophical or historical merit. For, this proposition conflates works of art and science (the texts of the play Timon and of the paper A structure for Deoxyribose Nucleic Acid), both of which are unique, and their semantic content (the insights into human affects provided by Timon and the concept of the DNA double helix), both of which are commonplace as well as unique.     

Grief as method: topographies of grief,care, and fieldwork from Northwest Arkansas to New York and the Marshall Islands

Abstract

When we grieve during fieldwork, our grief forms new geographies of knowledge production and emotion. In this article, I use autoethnography to theorize my grief during fieldwork following the death of my sister. I examine grief’s methodological implications using the concept of ‘grief as method,’ an emotionally-inflected practice that accounts for the vulnerability produced by grief. By centering vulnerability, ‘grief as method’ also urges researchers to consider the practices and politics of ‘caring with’ our research subjects and caring for ourselves, raising larger questions about the role of care in research. Furthermore, this article demonstrates how grief’s geographical features—its mobility, its emergence in new sites and landscapes, and its manifestation as both proximity and distance—shape ‘grief as method’ profoundly. I examine grief’s spatial implications by building on Katz’s ‘topography’ to theorize a ‘topography of grief’ that stitches together the emotional geographies of researchers, blurring both spatial divisions (‘the field’ vs. ‘the not-field’) and methodological ones (the ‘researcher-self’ vs. the ‘personal-self’). If we see grief as having a topography, then the relationships between places darkened by grief come into focus. Moreover, by approaching grief methodologically, we can better understand how field encounters—relationships between people—are forged through grief. ‘Grief as method,’ in offering a spatial analysis of grief’s impact on fieldwork, envisions a broader definition of what engaged research looks like and where it takes place.     

Russian Revenues from Oil and Gas Exports: Flow and Taxation

A senior Japanese economist traces the flows of revenue derived from oil and gas exports through the Russian economy. The author examines the use of revenues and investigates their contribution to Russia's state and regional budgets in the form of taxes. After detailing the methodological difficulties encountered in measuring revenue streams statistically, he proceeds to approximate their magnitude through intensive use of input-output table data and budget statistics provided by the Russian Federation Ministry of Finance. His investigation of the list of destination countries for Russian oil and petroleum products exports has interesting implications for the study of capital flight from Russia to the West.

A Spanish Man‐o‐War in New Zealand? The 1864 wreck of Grafton and its lessons for pre‐Cook shipwreck claims

This paper considers the 1864 wreck of Grafton in the Auckland Islands, and its implications for wreck analysis and pre‐Cook exploration claims. The captain of Grafton, Thomas Musgrave, stated that the schooner was built from the wreck of a Spanish man‐o‐war, and archaeological analysis of the wreck found that the timbers are a tropical South American species, and had possibly been reused. The implications of this are clear; it is possible that timbers that originated in pre‐Cook (1769) ships lie in New Zealand, but without a full understanding of the historical and archaeological context of any such timbers, including their reuse in later ships, it is not possible to claim proof of pre‐Cook European exploration of New Zealand.
