Correlating archaeological and palaeoenvironmental records using a Bayesian approach: a case study from Sutton Common,South Yorkshire,England

This paper presents a case study aimed at correlating archaeological ‘events’ (obtained from radiocarbon measurements and dendrochronology) from the site of Sutton Common with a radiocarbon-dated pollen sequence obtained from a palaeochannel deposit adjacent to the area of the main archaeological activity. It demonstrates the use of a Bayesian approach to quantifying whether the timing of palynological ‘events’ interpreted as reflecting anthropogenic impacts are likely to be associated with archaeological ‘events’. The results suggest that Bronze Age activity in the form of a mortuary enclosure and associated cremation burials are probably not contemporary with the palynological evidence for disturbance to the oak–hazel woodland in this period. Subsequent evidence for local woodland clearance and agriculture is estimated to precede the construction of the large Iron Age enclosure in 372 BC, with increases in ‘anthropogenic indicators’ following this ‘event’. The construction of the site does not appear to have had a pronounced impact on the local vegetation, with hazel the only woody taxon to show clear reductions. Despite the use of a substantial number of oak timbers in the enclosure palisade, percentages of oak remain remarkably stable. Later farming activity on the site probably post-dates the end of activity in the enclosures. The value of the methodology is discussed in relation to quantifiable and robust correlations of archaeological and palaeoenvironmental narratives of landscape and human activity.     

The impact of gravity waves on nitric oxide in the lower thermosphere

Observations of nitric oxide (NO) by the Solar Mesosphere Explorer (SME) during equinox indicate a lower-thermosphere equatorial minimum which is at variance with theoretical predictions. To address this discrepancy a zonally averaged model of the thermosphere and upper mesosphere is used to evaluate the influence of a latitude variation in turbulence. Five numerical simulations were performed with different latitude structures of eddy diffusion (K_T), ranging from uniform in latitude, peaks at low, mid-, or high-latitude, to a hemispherically asymmetric distribution. A local increase in eddy diffusion causes the lower thermosphere to cool and induces a latitude pressure gradient that drives horizontal and vertical winds. The circulation, turbulent transport and temperature dependent chemistry act to change the distribution of species. Comparison of the model predictions of NO with SME data, and simulated wind and temperature structure with empirical climatology, indicates a preference for a midlatitude peak in K_T.     

HISTORIA MAGISTRA VITAE,INTERRUPTING: THUCYDIDES AND THE AGONISTIC TEMPORALITY OF ANTIQUITY AND MODERNITY

In this essay I discuss Koselleck's thesis on the dissolution of historia magistra vitae in modernity with a view to exploring how the modern historiographical engagement with Thucydides entails qualifications of this argument. Focusing on Barthold Georg Niebuhr's contextualization of Thucydides in a new temporality of “ancient and modern history,” I examine how modernity is caught between conflicting notions of its own prehistory, and that this conflict suggests that the forward‐leaping qualities of Neuzeit were co‐articulated with other temporal notions, and particularly an idea of historical exemplarity associated with historia magistra vitae. This plurality of times highlights an agonistic temporality linking antiquity and modernity: a model of conflicting times inscribed in a dialogue through which modern historiography interrupted the “useful” history of antiquity, while simultaneously being itself interrupted by it. By following this dialogue, I seek to test two interrelated hypotheses: a) that modernity produced a multitemporal scheme in which the ideas of differential time and the future were intertwined with a notion of historia magistra vitae as meaningful and sense‐bearing time; and b) that contradictions in this scheme arising from the modern confrontation with Thucydides's poetics challenges the opposition between historia magistra vitae and modern historical sense and configures a temporality that is self‐agonistic in the sense that it confronts historical actors before and beyond the terms through which they may be able to give it meaning. Formulated as a poetics of the possible, this notion is approached as a corrective alternative to the modern consideration of the future as distanced from the space of experience, but nonetheless as grounded in actuality and therefore largely mastered by human knowledge and action.     

Auroral riometer absorptions and the F-region disturbances observed over a wide range of latitudes

Standard riometer data from a southern auroral station were compared with ionograms obtained at five stations positioned from sub-auroral to equatorial latitudes. The rapid onset in riometer absorption, during intense substorm activities in an equinoctial period, was associated with a sequential propagation of ionospheric disturbances deduced from the F-region parameters h′F and range spread-F. The time shift between absorption maxima and extrapolated commencement times of the disturbances was consistent with the presence of large-scale travelling ionospheric disturbances (TIDs), propagating equatorwards with velocities lying typically in the range 600–900 m s⁻¹, and with a median velocity of 720 m s⁻¹. It is suggested that the onset of TIDs is associated with high-energy particle precipitation, manifested by the occurrence of auroral absorption events. Similarity of absorption increases at the southern and northern conjugate points, found from a previous riometer study, would indicate that large-scale TIDs are simultaneously generated in both hemispheres.     

Fractal analysis of veins in Permian carbonate rocks in the Lingtanchang anticline,western China

Statistical analysis of the thickness distribution of veins in the Lingtanchang structure, southern Sichuan basin, western China, indicates that vein thickness conforms to fractal character and a power‐law distribution, whereas various distributions of veins are indicated by both the spacing distribution and the C_v values. According to geometry and structure, the veins in the Lingtanchang structure can be divided into confined and through‐going veins. The statistical analyses show that confined intralayer veins are consistent with a power‐law distribution in thickness, with D_t values of 1.1–1.7 and a log‐normal distribution in spacing with C_v values of 0.8–0.9. The confined intra‐ to interlayer veins show D_t values of 1.0–1.3 and an exponential distribution in spacing, with C_v values of 0.9–1.0, indicating an unconnected vein network with weak ability for paleofluid flow. However, the through‐going veins show the lowest D_t values of 0.6–0.8 with a power‐law distribution in thickness and power‐law to exponential distribution in spacing with C_v values of 1.5–3.2. Differences in spacing distribution and in the thickness of veins can be explained by different stages of vein growth from confined to through‐going veins. Such processes are dominant with percolating cluster models, which significantly controls spatial distribution of veins and paleofluid flow, and therefore the reservoir conditions in the southern Sichuan basin.     

Atmospheric gravity waves and sporadic-E

Observations of atmospheric gravity waves have identified several occasions when a wave-group propagating upwards can be associated first with a sporadic-E layer whose total electron content varies periodically, and later with a disturbance in the F-region varying with the same period. This paper reports four examples of such behaviour.     

When Druid went to jail: returned migrants,Irish prisoners,and Tom Murphy's Conversations on a Homecoming

Irish playwright Tom Murphy became Writer-in-Association with Druid Theatre of Galway, Ireland, in September 1983. The partnership began with Druid's production of Murphy's Famine (1968) in February 1984, and was followed by a lunchtime production of On the Outside (written in 1959 with Murphy's friend Noel O'Donoghue). Druid premiered Murphy's Bailegangaire (1985) in December 1985 and Conversations on a Homecoming in April 1985. Druid toured Conversations locally, nationally, and internationally for two and a half years. In February 1987, Druid presented the play at three Irish prisons. This article attempts to reveal how the prison audiences related to a play about a returned migrant; and to discover what prompted the professional company to perform in Irish prisons.     

Palaeolimnological impacts of early prehistoric farming at Lough Dargan,County Sligo,Ireland

This study provides a unique method of inquiry for archaeological investigation with an aim to assess the intensity and effects of Neolithic and Bronze Age farming practices at Lough Dargan, northwest Ireland, through a multi-proxy analysis of a lake sediment core. Chironomid (non-biting midge fly) subfossils and lake sediment geochemistry (δ¹³C, δ¹⁵N and C:N ratios) were used to assess changes in limnological conditions through time. The limnological data were compared with macroscopic charcoal concentration and pollen data to examine the potential influence that early farmers had on a freshwater lake system within a prehistorically active catchment. Results from the chironomid analysis show that the first substantial period of agricultural activity in the early Neolithic (c. 3730–3190 BC) resulted in a temporary shift to more eutrophic lake conditions. There is evidence of animal husbandry with substantial levels of animal waste reaching the lake, leaving an imprint in the geochemical record of increased δ¹⁵N values and decreased δ¹³C values and C:N ratios during this time. The chironomid community reverted back to its pre-impacted state c. 3190 BC in response to a period of reduced farming (c. 3390–3000 BC) which eventually led to a distinct lull in activity, with possible cessation of farming from 3000 to 2700 BC. A return to eutrophic conditions coincided with the gradual return of agriculture, with more permanently altered lake conditions dominating from 2400 BC, even during a 250-year period of reduced human activity commencing at c. 1440 BC. Increased sedimentation rate, along with increases in δ¹³C, δ¹⁵N and C:N, the presence of chironomid taxa indicative of erosion, more eutrophic lake conditions and high concentrations of macroscopic charcoal all point to more intensive land use practices during the Bronze Age. Palaeolimnological data exhibited an immediate response to intensified farming during this time, and were especially responsive to pastoral farming due either to scale of activity or proximity to the lakeside. The success of this study demonstrates the effectiveness of palaeolimnological analysis in the investigation of prehistoric farming. This approach will help inform Neolithic and Bronze Age land-use practice and human–environment relations in the region, and highlights the potential for chironomid-based archaeological research.     

The complete Himerius translated and explained

The Alexander Romance depicts Alexander going alone to the court of Darius disguised as his own messenger, dining with the Persians and advancing his own reputation as a munificent king. This episode substitutes a fictional scene for a number of dramatic banqueting incidents in the historical record that cast Alexander in a negative light, specifically, the burning of Persepolis, the proskynesis affair, and the wedding at Susa, which are all banqueting scenes concerned with Alexander’s generosity, reputation, and relations with the Persians. It is also an opportunity for intertextual allusion, especially to Homer and Herodotus. It is, further, only one of many occasions in the Romance when Alexander is said to go alone to visit his enemies in disguise; these episodes integrate the composition and evince a concern with the treatment of ambassadors. It is finally one of the only instances of the explicit characterization of Alexander in the Romance.     

A comparison of northern and southern hemisphere TEC storm behaviour

Changes in total electron content during magnetic storms are compared at stations with similar geographic and geomagnetic latitudes and eastward declinations in the northern and southern hemispheres.Mean patterns are obtained from 58 storms at ±35° and 28 storms at ± 20° latitude. The positive storm phase is generally larger (and earlier) in the southern hemisphere, while negative storm effects are larger in the north. These changes reduce the normal asymmetry in TEC between the two hemispheres. Composition changes calculated from the MSIS86 atmospheric model agree well with the maximum decreases in TEC in both seasons (when changes in the F-layer height are ignored). Recovery occurs with a time constant of about 35 h; this is 50% longer than in the MSIS86 model. There is a marked diurnal variation at 35°S, with a rapid overnight decay and enhanced values of TEC in the afternoon. This pattern is inverted (and weaker) at 35°N, where night-time decay is consistently slower than on undisturbed nights. These results require a diurnal change in composition of opposite sign in the two hemispheres, or enhanced westward winds at night changing to eastward near sunrise. There is some evidence for both these mechanisms. Following a night-time sudden commencement there is a large annual effect with daytime TEC increasing for storms near the June solstice and decreasing near December. Storms occurring between November and April tend to give large, irregular increases in TEC for several days, particularly at low latitudes. In summer and winter at both stations, the mean size of the negative phase does not increase for storms with K_p> 6. The size of the positive phase is proportional to the size of the change in a_p in winter, while in summer a positive phase is seen only for the larger storms.     

Quantitative computerized tomography for the diagnosis of osteopenia in prehistoric skeletal remains

In this study, we examine the value of bone density assessed by computed tomography (QCT) of the right tibia in the diagnosis of low bone mass in prehistoric bones. Trabecular bone mass (TBM) was assessed by histomorphometry in undecalcified bone sections of a small part of the proximal epiphysis of the right tibia of 78 prehispanic individuals. Bone density was also assessed in the proximal epiphysis of the right tibia, in an area of cancellous bone immediately adjacent to the wedge which was destined to histomorphometry, with the aid of a Tomoscan 60 TX™ (Philipps Medical System, Eindhoven, The Netherlands) using a phantom of hydroxyapatite included in plastic resin at three known concentrations (50, 100 and 200 mg/cc) and ethanol as fat equivalent. Bone density (as bone hydroxyapatite concentration in milligram per cubic centimeter) was calculated by means of a specific software tool (QCT Bone Mineral Analysis System, Image Analysis, California). We compared bone density assessed with QCT with TBM in these individuals, and also, with the results obtained from a modern control group. We calculated the median TBM of the prehispanic sample and tested the sensitivity, specificity, and overall accuracy of QCT in diagnosing TBM values below the median. We later performed the same analyses on 24 more prehispanic individuals. Both QCT (t = 5.61, p < 0.001) and TBM (t = 3.79, p < 0.001) were significantly lower among the prehispanic individuals than among the control ones. QCT showed a significant relationship with TBM (r = 0.41, p < 0.001). QCT values below 100 mg/cc serve to establish a diagnosis of low TBM values with a sensitivity of 82.1% and a specificity of 41%. In the test group sensitivity was 83.3% and specificity, 50%.     

Trade,tribute and household responses

During the Late Middle Ages the combined pressures from the stately tributary organizations of Novgorod and Norway, in cooperation with the capitalist organization of the German Hansa, seem to have driven the hunting population of Varanger in East Finnmark to exploit the wild reindeer resource heavily. The article deals with how a Saami household who lived in a turf house on a peninsula in the present municipality of Nesseby (Unjárgd) dealt with the situation.     

“Thrown Like Chaff in the Wind”: Excavation, Memory and the Negotiation of Loss in the Scottish Highlands

Memory has become an important area of research in historical archaeology over the last decade with an increasing focus on retrieving the narratives of subaltern groups and painful memories of conflict, displacement and loss. Drawing on ethnographic research, I explore how archaeological excavation provides an arena for sharing, negotiating and contesting difficult forms of memory associated with the Highland Clearances. I argue that the Clearances involve a kind of “postmemory” revolving around a series of iconic motifs and that this provides a framework for interpretation and action in the present. Coherence is produced not through the “excavation” of silenced narratives, but through social processes of performance, negotiation and “composure,” as people engage in a dialogue with past, present and future.     

民国时期乡村建设运动的农村改造模式

The campaign of rural reconstruction during the republic period was a comprehensive exploration of the changes in the traditional countryside. It establishes that the transformation of the countryside is a key issue in China’s modernization and attempts to find an effective way to connect the two. In political transformation, it promoted the system of democratic autonomy; in the transformation of agricultural economy, it advocated a joint-stock system with enterprise and market features; in the transformation of farmers’ quality, it tried to equip the farmers with basic modern cultural and technological knowledge. The characters above show a pattern of relatively systematic reconstruction of the countryside with modern significances.

Rachel and Lea. or: On the survival of outdated paradigmas in the study of the origin of Israel,II

ABSTRACT

Reader-oriented intertextuality opens perspectives to see the in-terpretation of the Hebrew Bible in the New Testament and in rabbinic litera-ture in a new light. This article discusses possible readings of the crux inter-pretum Leviticus 12,2 in the New Testament (Hebrews 11,11) and in rabbinic literature. It shows that both play with manifold meanings and facets of texts from the Hebrew Bible in a sometimes associative way, linking different con-texts with one another and creating a new intertextual network.     

Placing Masculinities and Geography

Introduction There has been an increasing focus in feminist and pro-feminist inspired studies on examining men, male subjectivities and masculinities in the decade since Gender, Place and Culture began publication. Our aim in this article is to provide readers with a brief overview of some of this recent research, and then to place these works within a critique of the Anglocentric character of geographic knowledge production. The article proceeds in the following manner. We begin with a brief definition of masculinity, in order to stress its temporal and geographical contingency. We follow this discussion with a brief review of some of the research on masculinities undertaken in the past two decades, with a particular emphasis on studies of the social and cultural geographies of masculinity completed in the decade since Gender, Place and Culture began publication. It is important to note that our review is far from exhaustive, but rather, more indicative. Our purpose here is to provide a context for our subsequent critique of a specific scaling of knowledge that constitutes much of the context for the way that work on masculinities is understood in Anglo-American geography.     

The Medieval Village at Garrow Tor,Bodmin Moor,Cornwall

SUMMARY

The site chosen for excavation in the medieval village at Garrow proved to be a platform-house, a variant of the long-house, a widespread form of peasant dwelling. Both types provided for the shelter of man and his beasts under one roof; in its early form, as here, it consisted of a living-room and byre separated by a passage connecting with an entrance in each long side. The platform-house was suited to meet the hard conditions of life in a hilly country of heavy rainfall. It was built on an oblong platform constructed with its long axis at right angles to the contours of the hillside. Thus the house gained considerable protection from wind and rain.

Two outstanding features were the hearth with fireback centrally placed on the floor in the upper room and the manger which was in situ in the byre. Near the house was a small barn. The two buildings stood in a small enclosure. Pottery found in the house and barn and in the fields connected with the settlement showed that there was occupation from the thirteenth to the fifteenth centuries. Inhabited farmhouses of this type can still be seen in Cornwall.¹     

The Eslington Sword and the Kingdom of Northumbria

NEW DISCOVERIES may indicate the location of a previously unknown early medieval burial ground in central Northumberland. Objects discovered during the course of metal-detecting include an assemblage with a folded, pattern-welded sword and zoomorphic shield mount. Excavation indicated near total destruction of deposits as a result of post-medieval land-use and only Bronze-Age burials inserted into bedrock remained intact. Three putative early medieval burials are identified here, with the largest assemblage associated with a high-status male. The sword and shield mount from this assemblage are comparable with finds from high-status burials in southern and eastern England. Together with the landscape context of the site, the assemblage provides evidence for the burial practices of an emerging Northumbrian elite in the late 6th century ad.     

Social stratigraphy in Late Iron Age Switzerland: stable carbon,nitrogen and sulphur isotope analysis of human remains from Münsingen

The Iron Age cemetery of Münsingen in Switzerland with 220 abundantly equipped burials marked a milestone for Iron Age research. The horizontal spread throughout the time of its occupancy laid the foundation for the chronology system of the Late Iron Age. Today, skulls of 77 individuals and some postcranial bones are still preserved. The aim of the study was to obtain information about diet, mobility and social stratification of the individuals. Stable isotope ratios of carbon, nitrogen and sulphur were analysed for 63 individuals. For all of them, C₃ plants were found to be the staple food. There are significant differences between males and females in δ¹³C and δ¹⁵N values. This points to a gender restriction in the access to animal protein with males probably having more access to meat and dairy products. Differences in δ¹⁵N values were also observed for different age classes. δ³⁴S values indicate a terrestrial-based diet with no significant intake of marine or freshwater fish. Seven adults with enriched δ³⁴S values might have immigrated to Münsingen, four of which were found in the oldest part of the cemetery. Furthermore, possible changes of the vegetation are indicated by the more positive stable carbon ratios in the later phases. The results lead to the suggestion that especially males buried with weapons might have played a special role in the Iron Age society.     

Big Pharma's Internationalization of R&D to China

China's increasing integration into the global pharmaceutical value chain is occurring at a time when big pharma's traditional R&D model has entered a period of crisis, and when China faces significant challenges in providing healthcare for its huge and rapidly ageing population. Despite China's ambitions of promoting its own pharmaceutical sector, it is likely to continue to depend for some time on significant contributions from foreign companies. While this situation provides considerable opportunities for big pharma companies to expand their markets in China, they are also hoping that offshoring aspects of their R&D to China may contribute to reconfiguring their current R&D model with its weak record of producing new drugs. Drawing on interviews with a small number of pharma R&D centres in Shanghai, patent analyses and industry reports, we provide insights into both the challenges and the opportunities associated with the early stages of establishing such centres in an emerging region with a rapidly growing market. This paper contributes towards a more nuanced view of the internationalization of R&D in emerging regions.
