'Where water wells up from the earth’: excavations at the findspot of the Late Bronze Age hoard from Broadward, Shropshire

The paper begins by considering the importance of springs as a focus for votive deposits in Bronze Age Britain. This is not a new idea, but nowhere has this association been examined through the excavation of one of these features. The point is illustrated by excavation at the findspot of a famous group of Late Bronze Age weapons, the Broadward hoard, discovered in 1867. Little was known about the site, where it was found or the character of the original deposit, but a study of contemporary accounts of the hoard, combined with geophysical and topographical surveys, led to small-scale excavation in 2010, which showed that the deposit had most probably been buried in a pit on the edge of a spring. Other finds associated with the spring included an Early Bronze Age macehead, a Roman pot and various Saxon and medieval animal bones. The latest deposit, with a post-medieval carbon date, included a wooden knife or dagger. An adjacent palaeochannel provided an important environmental sequence for this part of the English–Welsh borderland and suggests that the Late Bronze Age hoard had been deposited not far from a settlement. A nearby earthwork enclosure was associated with a clay weight, which may be of similar date. Despite the limited scale of the fieldwork, it illustrates the potential for treating springs associated with artefact finds on the same terms as other archaeological deposits.

An assessment of the impact of trees upon archaeology within a relict wetland

An evaluation of a surviving stretch of the Abbot's Way, in the Somerset Levels and Moors, was undertaken to assess the consequences of the previous management regime and inform future management of the site. The scheduled site appeared to have been dewatered and desiccated as a consequence of tree planting and the effects of a deep, adjacent drainage ditch during the previous decade. The evaluation considered the condition of the Neolithic timbers and associated palaeoenvironmental record from three trenches and, where possible, compared the results with those obtained form the 1974 excavation (Girling, 1976). The results of this analysis suggest that the hydrological consequences of tree planting and colonization had a detrimental effect on both the condition of the timbers and insect remains. However, pollen and plant macro-fossils survived well although there was modern contamination. A trench opened outside the scheduled area. where the ground was waterlogged and supported a wet acid grassland flora, revealed similar problems of survival and condition. This almost certainly reflects a period of peat extraction and an associated seasonally fluctuating water table in the 1950s and 1960s; in fact pollen survived better in the scheduled dewatered area. These results are compared with those recovered from the Sweet Track which was evaluated in 1996. Both sites have been subject to recent tree growth but the Sweet Track has been positively managed in terms of hydrology. The most notable difference between the two sites is that insects and wood survived better at the Sweet Track sites than at the Abbot's Way. Insects seem to be a more sensitive indicator of site desiccation than plant remains. It is recommended that any programme of management of wetland for archaeology should avoid deliberate tree planting and natural scrub and woodland generation. It should also take into account past as well as present land use.

Glastonbury Abbey: archaeological investigations 1904-79

This volume reports on the results of the Glastonbury Abbey Archaeological Archive Project, a collaboration between the University of Reading and the Trustees of Glastonbury Abbey, funded principally by the Arts and Humanities Research Council. The project has reassessed and reinterpreted all known archaeological records from the 1908–79 excavations and made the complete dataset available to the public through a digital archive hosted by the Archaeology Data Service (http://dx.doi.org/10.5284/1022585). The scope of the project has included the full analysis of the archaeological collections of Glastonbury Abbey by thirty-one leading specialists, including chemical and compositional analysis of glass and metal and petrological analysis of pottery and tile, and a comprehensive geophysical survey conducted by GSB Prospection Ltd. For the first time, it has been possible to achieve a framework of independent dating based on reassessment of the finds and radiocarbon dating of surviving organic material from the 1950s excavations. The principal aim of the Glastonbury Abbey Archaeological Project was to set aside previous assumptions based on the historical and legendary traditions and to provide a rigorous reassessment of the archive of antiquarian excavations. This research has revealed that some of the best known archaeological ‘facts’ about Glastonbury are themselves myths perpetuated by the abbey’s excavators.

Thin place exhibition

Thin Place is an interdisciplinary project which aims to find connections between the fields of art, archaeology, astrophysics, astrology, alternative therapy, poetry and theology. The nature of this project goes beyond the exhibition and incorporates a symposium, catalogue and education programme which will attempt to dissolve the boundaries that separate fields of knowledge and, in so doing, create a thin place at Oriel Myrddin. The five exhibiting artists and the other contributors to this project have produced work that is concerned with or responds to two particular locations: West Wales and the West of Ireland. In ancient times it was believed that the West was where departed souls easily entered Otherworlds. This is because the delineation between worlds was more permeable along these coasts. Archaeological excavations reveal that West Wales and the West of Ireland were thought by some to be ‘thin places.’ In considering the notion of a ‘thin place’, this exhibition addresses the ways in which we value our relationship with Place, particularly in landscapes where human and non-human relationships are well established.

'The debatable territory where geology and archaeology meet': reassessing the early archaeobotanical work of Clement Reid and Arthur Lyell at Roman Silchester

The first large-scale archaeobotanical study in Britain, conducted from 1899 to 1909 by Clement Reid and Arthur Lyell at Silchester, provided the first evidence for the introduction of Roman plant foods to Britain, yet the findings have thus far remained unverified. This paper presents a reassessment of these archaeobotanical remains, now stored as part of the Silchester Collection in Reading Museum. The documentary evidence for the Silchester study is summarised, before the results are presented for over a 1000 plant remains including an assessment of preservation, identification and modern contamination. The dataset includes both evidence for the presence of nationally rare plant foods, such as medlar, and several archaeophytes. The methodologies and original interpretations of Reid and Lyell’s study are reassessed in light of current archaeobotanical knowledge. Spatial and contextual patterns in the distribution of plant foods and ornamental taxa are also explored. Finally, the legacy of the study for the development of archaeobotany in the 20th century is evaluated.

Integrating archaeology and palaeoecology to understand Jê landscapes in southern Brazil

Around AD 1000, the southern Brazilian highlands witnessed a convergence of phenomena: climatic change, the abrupt expansion of Araucaria forest and the appearance of large pit-houses and monumental mound and enclosure complexes, which signal fundamental socio-political and ideological change amongst southern proto-Jê (SPJ) groups. These developments raise intriguing questions regarding the relationships between people, vegetation and climate over the last 2000 years.

The Mesolithic-Neolithic transition in the Channel Islands: maritime and terrrestrial perspectives

This paper investigates the Mesolithic-Neolithic transition in the Channel Islands. It presents a new synthesis of all known evidence from the islands c. 5000-4300 BC, including several new excavations as well as find spot sites that have not previously been collated. It also summarises – in English – a large body of contemporary material from north-west France. The paper presents a new high-resolution sea level model for the region, shedding light on the formation of the Channel Islands from 9000-4000 BC. Through comparison with contemporary sites in mainland France, an argument is made suggesting that incoming migrants from the mainland and the small indigenous population of the islands were both involved in the transition. It is also argued that, as a result of the fact the Channel Islands witnessed a very different trajectory of change to that seen in Britain and Ireland c. 5000-3500 BC, this small group of islands has a great deal to tell us about the arrival of the Neolithic more widely.

Patterns of hominin occupation and cultural diversity across the Gebel Akhdar of Northern Libya over the last ~200 kyr

Excavations at Haua Fteah cave in Cyrenaica, Libya, have revealed a cultural sequence that may span the last glacial–interglacial-glacial cycle. The TRANS-NAP project has been re-excavating Haua Fteah and conducting geoarchaeological survey of an ecologically diverse landscape that includes the fertile Gebel Akhdar and littoral, pre-desert, and desert biomes. A major aim of this project is to characterize cultural and environmental changes across the region and correlate the surface archaeology with that from Haua Fteah. To date, 181 sites have been recorded, ranging from the Middle Stone Age (MSA) to Late Stone Age (LSA). Their geographic distribution suggests temporal variation in patterns of hominin habitat preference, with significantly more LSA than MSA sites at higher elevations. The surface archaeology also points to substantial spatiotemporal technological variation within the MSA. These patterns may be explained by both paleoenvironmental change and paleodemographic shifts in the region, resulting in a variety of hominin adaptive responses.

Towards high-resolution shell midden archaeology: Experimental and ethnoarchaeology in Tierra del Fuego (Argentina)

This paper discusses the ongoing ethnoarchaeological research carried out in Yamana shell middens of Tierra del Fuego. Ethnoarchaeology is used in this research as a tool to improve the archaeological methodology by testing it against anthropological, ethnographical and ethnological sources for achieving more accurate reconstructions of past societies. The ethnographical/ethnological information also is coupled with an experimental approach devised to understand physical and social processes, such as site formation processes and resource use and management. Specifically, this experimental approach was applied to the archaeological sites Tunel VII and Lanashuaia I (Tierra del Fuego, Argentina). (C) 2011 Elsevier Ltd and INQUA. All rights reserved.

Book Review of Archaeology as a Process: Processualism and Its Progeny by Michael J. O'Brien, R. Lee Lyman, and Michael Brian Schiffer

The field of archaeology incorporates a confusing assortment of ideas and approaches to the record. With studies ranging widely in ideology and goals, from strict descriptive materialism to sociological interpretation, language used to communicate key concepts (not to mention which concepts are key) also varies widely, resulting in low levels of mutual interest and intelligibility across the discipline. Archaeologists commonly ignore the majority of available literature as a result, further widening intellectual chasms.

LAGOA SANTA REVISITED: AN OVERVIEW OF THE CHRONOLOGY, SUBSISTENCE, AND MATERIAL CULTURE OF PALEOINDIAN SITES IN EASTERN CENTRAL BRAZIL

Lagoa Santa, a karstic area in eastern Central Brazil, has been subject to research on human paleontology and archaeology for 175 years. Almost 300 Paleoindian human skeletons have been found since Danish naturalist Peter Lund's pioneering work. Even so, some critical issues such as the role of rockshelters in settlement systems, and the possible paleoclimatic implications of the peopling of the region have yet to be addressed. We present some results obtained from recent excavations at four rockshelters and two open-air sites, new dates for human Paleoindian skeletons, and a model to explain the cultural patterns observed so far. It is also argued that the Paleoindian subsistence system at Lagoa Santa was similar to other locations in South America: generalized small-game hunting complemented by fruits, seed, and root gathering.

The evolution of health status and chronic conditions in Catalonia, 1994-2006: the paradox of health revisited using the Blinder - Oaxaca decomposition

[EN] Background: The paradox of health refers to the improvement in objective measures of health and the increase in the reported prevalence of chronic conditions. The objective of this paper is to test the paradox of health in Catalonia from 1994 to 2006. Methods: Longitudinal cross-sectional study using the Catalonia Health Interview Survey of 1994 and 2006. The approach used was the three-fold Blinder - Oaxaca decomposition, separating the part of the differential in mean visual analogue scale value (VAS) due to group differences in the predictors (prevalence effect), due to differences in the coefficients (severity effect), and an interaction term. Variables included were the VAS value, education level, labour status, marital status, all common chronic conditions over the two cross-sections, and a variable for non-common chronic conditions and other conditions. Sample weights have been applied. Results: Results show that there is an increase in mean VAS for men aged 15-44, and a decrease in mean VAS for women aged 65-74 and 75 and more. The increase in mean VAS for men aged 15-44 could be explained by a decrease in the severity effect, which offsets the increase in the prevalence effect. The decrease in mean VAS for women aged 65-74 and 75 and more could be explained by an increase in the prevalence effect, which does not offset the decrease in the severity effect. Conclusions: The results of the present analysis corroborate the paradox of health hypothesis for the population of Catalonia, and highlight the need to be careful when measuring population health over time, as well as their usefulness to detect population's perceptions.

Heave of large excavations in clay: modelling and analysis of two british case-histories

ABSTRACT Il presente lavoro vuole introdurre la problematica del rigonfiamento del terreno a seguito di grandi scavi in argilla. Il sollevamento del terreno dopo lo scavo può passare inosservato ma sono numerosi i casi in cui il rigonfiamento dura per molti anni e addirittura decenni, Shell Centre, London, Lion Yard, Cambridge, Bell Common, London, ecc. Questo rigonfiamento il più delle volte è impedito dalla presenza di fondazioni, si genera quindi una pressione distribuita che se non considerata in fase di progetto può portare alla fessurazione della fondazione stessa. L’anima del progetto è la modellazione e l’analisi del rigonfiamento di grandi scavi in argilla, confrontando poi i risultati con i dati reali disponibili in letteratura. L’idea del progetto nasce dalla difficoltà di ottenere stime e previsioni attendibili del rigonfiamento a seguito di grandi scavi in argilla sovraconsolidata. Inizialmente ho esaminato la teoria e i fattori che influenzano il grado e la velocità del rigonfiamento, quali la rigidezza, permeabilità, fessurazione, struttura del suolo, etc. In seguito ho affrontato lo studio del comportamento rigonfiante di argille sovraconsolidate a seguito di scarico tensionale (scavi), si è evidenziata l’importanza di differenziare il rigonfiamento primario e il rigonfiamento secondario dovuto al fenomeno del creep. Il tema centrale del progetto è l’analisi numerica tramite Flac di due grandi scavi in argilla, Lion Yard, Cambridge, e, Bell Common, London. Attraverso una dettagliata analisi parametrica sono riuscito a trovare i migliori parametri che modellano il comportamento reale nei due casi in esame, in questo modo è possibile arrivare a stime e previsioni attendibili del fenomeno rigonfiante del terreno a seguito di grandi scavi. Gli scavi modellati Lion Yard e Bell Common sono rispettivamente in Gault Clay e London Clay, grazie a famosi recenti articoli scientifici sono riuscito a evidenziare la principali propietà che diversificano i due terreni in esame, tali propietà sono estremamente differenti dalle normali caratteristiche considerate per la progettazione in presenza di terreno argilloso; sono così riuscito a implementare i migliori parametri per descrivere il comportamento dei due terreni nei diversi modelli. Ho inoltre studiato l’interazione terreno-struttura, la pressione esercitata dal rigonfiamento del terreno è strettamente funzione delle caratteristiche di connesione tra fondazione superficiale e muro di sostegno, tale pressione non deve essere ignorata in fase progettuale poichè può raggiungere importanti valori. Nello scavo di Lion Yard, considerando la presenza delle fondazioni profonde ho evidenziato il fatto che il rigonfiamento crea una forza distribuita di taglio tra i pali di fondazione ed il terreno, anche tale sollecitazione dovrebbe essere considerata ai fini della progettazione. La problematica non si ferma solo sull’interazione terreno-fondazioni, infatti durante gli scavi di importanti fondazioni londinesi lo scarico tensionale ha creato uno spostamento significativo positivo verso la superfice di tratti di tunnel della metropolita, questo fenomeno può creare seri problemi di sicurezza nella rete dei trasporti pubblici. Infine sono stati messi a confronto i risultati del programma Flac con quelli di metodi semplificati, ho trovato che utilizzando il metodo iterativo di O’Brien i risultati sono simili alla realtà e il tempo di calcolo è molto inferiore di quello richiesto utilizzando Flac, 2-3 giorni. In conclusione posso affermare che grazie ad una dettagliata analisi parametrica è stato possibile stimare il rigonfiamento del terreno, argilla sovraconsolidata, nei due casi analizzati.
