Excavation of a small single-component prehistoric campsite in the coastal southern California foothills has provided evidence concerning the patterns and approximate rates of redistribution of archaeological materials caused by the burrowing pocket gopher, Thomomys bottae. Investigation of bimodal vertical distributions of both historic and prehistoric archaeological materials shows a close correspondence to the burrowing habits of pocket gophers in coastal California. Comparison of these bimodal distributions with a site chronology based upon diagnostic artifacts and C-14 dating suggests that, under certain soil conditions, downward displacement of archaeological materials may occur at rates averaging over 5% per century. The broader implications of the effects of faunalturbation upon the interpretation of archaeological assemblages are briefly discussed.

Regional Analyses

Bayesian analysis is now routinely applied for the construction of site-specific stratigraphic chronological models. Other approaches have analyzed the chronology of phases of archaeological activity across regions. The available radiocarbon results—the nature of the samples and their associations—provide the basis for what chronological questions it is possible to address for any site or region. In dealing with regional analyses, due consideration must be made of data selection. While data selection might be a relatively self-evident consideration in the analysis of a site chronology, working with data from a larger region poses a number of specific data selection issues. Robust association between dated samples and a particular type of diagnostic material culture or site may provide one means of producing regional chronologies. However, if the activity under investigation includes a number of different cultural traits, which are related but with each having a slightly different chronological currency, defining the temporal end of data selection becomes more problematic. This article presents one approach, using a case study from the British Mesolithic-Neolithic transition, with 880 simulation OxCal models used to investigate the effect of variously defining the end of a regional archaeological phase. The results emphasize that for a regional case study, sensitivity analysis may provide a useful tool to ensure representative models; the study also highlights the importance of comparing multiple model posteriors.

To examine the adaptations to low O2 and high CO2 among fossorial and nonfossorial rodents, hematological parameters were determined for laboratory rats, the valley pocket gopher (Thomomys bottae) from 250 m, and the mountain pocket gopher (T. umbrinus melanotis) from 3150 m. Hematocrit, hemoglobin concentration, and O2 capacity were higher in pocket gophers than in rats. Blood PO2 at 50% saturation and pH 7.4 was 33 mmHg for both gophers and 39 mmHg for rats. Bohr factors for all three rodents were similar (-0.55 to -0.61) but buffer value, delta log PCO2/delta pH, was -2.54 for T. umbrinus, -1.97 for T. bottae, and -0.98 for Rattus. Concentrations of total acid-soluble phosphates were 50–75% higher in gophers than in rats, while bicarbonate values were within the normal mammalian range. All three rodents had similar myoglobin concentrations in cardiac muscle. Myoglobin concentrations were significantly higher in skeletal muscles (diaphragm, gastrocnemius) of T. umbrinus when compared to T. bottae, and significantly higher in both gophers when compared to rats. These differences may constitute important adaptations to the hypoxia and hypercapnia in burrows; certain of these factors in pocket gophers respond to the additional stress of high altitude hypoxia.

Adverse Environmental Conditions

Northern pocket gophers (Thomomys talpoides) are fossorial herbivores that excavate belowground plant parts for food. In subalpine areas during autumn and winter, pocket gophers hoard plant parts in caches placed in or under snow. We examined the size and composition of 17 nival caches and tested the hypotheses that (i) cached food can provide complete energy and protein N sustenance during typical periods when burrowing is precluded by soil conditions, and (ii) cached food is a random sample of items encountered by burrowing gophers during tunnel excavation. Our data indicate that caches provide substantially more energy than protein in terms of a pocket gopher's daily maintenance requirements. Nevertheless, quantities stored are sufficient to allow individuals to endure commonly encountered adverse environmental conditions without entering negative energy or protein balance. Analysis of stomach contents and a comparison of cache composition to availability of plant species suggests that gophers consume high-protein items as they are encountered, and store low-protein items in caches.

Historical Centre

A landscape or site, which has been inhabited for long, consists of layers of history. This history is sometimes reserved in forms of small physical remnants, monuments, memorials, names or collective memories of destruction and reconstruction. In this sense, a site/landscape can be presumed as what Derrida refers to as a “palimpsest”. A palimpsest whose character is identified in a duality between the existing layers of meaning accumulated through time, and the act of erasing them to make room for the new to appear. In this study, the spatial collective memory of the Chahar Bagh site which is located in the historical centre of Shiraz will be investigated as a contextualized palimpsest, with various projects adjacent one another; each conceptualized and constructed within various historical settings; while the site as a heritage is still an active part of the city’s cultural life. Through analysing the different layers of meaning corresponding to these adjacent projects, a number of principals for reading the complexities of similar historical sites can be driven.

Landscape Quality

Attractive landscapes are diverse and resilient landscapes that provide a multitude of essential ecosystem services. The development of landscape policy to protect and improve landscape attractiveness, thereby ensuring the provision of ecosystem services, is ideally adapted to region specific landscape characteristics. In addition, trends in landscape attractiveness may be linked to certain policies, or the absence of policies over time. A spatial and temporal evaluation of landscape attractiveness is thus desirable for landscape policy development. In this paper, landscape attractiveness was spatially evaluated for Flanders (Belgium) using landscape indicators derived from geospatial data as a case study. Large local differences in landscape quality in (i) rural versus urban areas and (ii) between the seven agricultural regions in Flanders were found. This observed spatial variability in landscape attractiveness demonstrated that a localized approach, considering the geophysical characteristics of each individual region, would be required in the development of landscape policy to improve landscape quality in Flanders. Some trends in landscape attractiveness were related to agriculture in Flanders, e.g., a slight decrease in total agricultural area, decrease in dominance of grassland, maize and cereals, a decrease in crop diversity, sharp increase in the adoption of agri-environmental agreements (AEA) and a decrease in bare soil conditions in winter. The observed trends and spatial variation in landscape attractiveness can be used as a tool to support policy analysis, assess the potential effects of future policy plans, identify policy gaps and evaluate past landscape policy.

At the turn of the 20th century, children's play came under new and heightened scrutiny by urban reformers. As conditions in US cities threatened traditional notions of order, reformers sought new ways to direct urban-social development. In this paper I explore playground reform as an institutional response that aimed to produce and promote ideal gender identities in children. Supervised summer playgrounds were established across the United States as a means of drawing children off the street and into a corrective environment. Drawing from literature published by the Playground Association of America and a case study of playground management in Cambridge, MA, I explore playground training as a means of constructing gender identities in and through public space. Playground reformers asserted, drawing from child development theory, that the child's body was a conduit through which ‘inner’ identity surfaced. The child's body became a site through which gender identities could be both monitored and produced, compelling reformers to locate playgrounds in public, visible settings. Reformers' conviction that exposing girls to public vision threatened their development motivated a series of spatial restrictions. Whereas boys were unambiguously displayed to public audiences, girls' playgrounds were organised to accommodate this fear. Playground reformers' shrewd spatial tactics exemplify the ways in which institutional authorities conceive of and deploy space toward the construction of identity.

Second World

AbstractBy the outbreak of the Second World War in Britain, critics had spent several decades negotiating the supposed distinctions between highbrow and lowbrow culture, as recent scholarship has shown. What has received comparatively little attention is how the demands of wartime living changed the stakes of the debate. This article addresses this lacuna, exploring how war invited a reassessment of the relative merits of art and popular music. Perhaps the most iconic British singer of the period, Vera Lynn provides a case study. Focusing on her first film vehicle,We'll Meet Again(1942), I explore how Lynn's character mediated the highbrow/lowbrow conflict – for example, by presenting popular music as a site of community, while disparaging art music for its minority appeal. In so doing, I argue, the film not only promoted Lynn's star persona, but also intervened in a broader debate about the value of entertainment for a nation at war.
