Delivering, Assessing and Providing Feedback for Fieldwork Modules: A Case Study from Archaeology
In this paper we highlight some of the issues surrounding the delivery of fieldwork modules, using archaeological excavation as an example. There are a whole range of issues surrounding the assessment of fieldwork-based modules, and here we detail approaches we have adopted to ensure consistent delivery and assessment methods. In particular, we have written and launched a web resource which can be used to assist with both the delivery and assessment of fieldwork. Finally, we discuss issues surrounding feedback, and suggest a method for enhancing students’ feedback on field-based modules
Muddying the Waters: reconsidering Migration in the Neolithic of Britain, Ireland and Denmark
This paper explores the current narratives of migration for the start and spread of the Neolithic with a particular focus on the role that the new ancient DNA data have provided. While the genetic data are important and instructive, here it is argued that archaeologists should also consider other strands of evidence. More nuanced appreciations of migration as a long-term process can be created by exploring modern mobility studies alongside considerations of continued mobility throughout the Neolithic in Europe. We can also re-interpret the material evidence itself in the light of these approaches to help trace multiple possible links and migrations from multiple different origin points. This involves the investigation of complex, but connected, practices, such as monument construction and deposition across wider areas of northern Europe than are currently normally investigated. Such an approach will enable us to address long-term processes of movement, migration and interaction and investigate how new, shared social experiences emerged in a setting in which mobility and migration may have been the norm
Materialising descent: lineage formation in early Neolithic southern Britain.
This paper builds on the recent aDNA results from Hazleton North chambered tomb to explore how people might have repeatedly negotiated kinship, descent, and affinity in Early Neolithic southern Britain. Hazleton North was constructed around 3700 cal BC, was in use for less than a century, and – unlike many other Cotswold-Severn tombs – was never modified to alter the arrangement of chambers. The aDNA analysis from 35 individuals whose remains were deposited at the site revealed that 27 were biologically related and represented five sequential generations. Here we explore changing practices across those generations. We argue that Hazleton North was constructed to demonstrate the vitality of a lineage at a specific moment in time, while choices about who to entomb indicate an inclusive expansion of the lineage in the first two generations, which is not evident during the remaining generations. We argue that by the third generation lineage members increasingly chose to dispose of the remains of their dead elsewhere. Hazleton North was built in a landscape rich in earlier tombs, many of which were modified to produce long cairns with multiple chambers: some of those formed opposed pairs similar to the chambered areas at Hazleton North. We argue this was part of a growing trend in 'kinship work' which accentuated lineal descent and sub-lineage distinctions in the centuries around 3700 cal BC. However, deposition at Hazleton North was short-lived. This can be set in the local context of not only the construction and use of further chambered tombs but also increasing investment in larger corporate projects like causewayed enclosures. These enclosures formed new arenas where negotiations of descent and community were played out with increased intensity and in different ways to activities at chambered tombs. Overall, we argue that kinship, affiliation, and belonging were repeatedly renegotiated among the monument building communities of Early Neolithic southern Britain
Neolithic Explanations Revisited: Modelling the Arrival and Spread of Domesticated Cattle into Neolithic Britain
Set against the new chronological framework for the introduction and spread of the Neolithic into Britain this paper considers the logistics of introducing domestic cattle from continental Europe. Cattle were the most extensively utilised domestic animal at the start of the Neolithic and understanding the processes behind their introduction is critical for exploring early Neolithic farming systems. We begin by exploring the realities of creating a viable new animal population and then moving that population to Britain across the water from Continental Europe. Using a series of simulated models we demonstrate that only a very small number of cattle need to have been introduced into Britain in order to enable the uptake and spread of domestic cattle across the whole island. This, in turn, may effect how we consider the mechanisms involved in the adoption of the Neolithic, and can better inform our understanding of the kinds of processes involved in transition to the Neolithic
Psychosocial impact of undergoing prostate cancer screening for men with BRCA1 or BRCA2 mutations.
OBJECTIVES: To report the baseline results of a longitudinal psychosocial study that forms part of the IMPACT study, a multi-national investigation of targeted prostate cancer (PCa) screening among men with a known pathogenic germline mutation in the BRCA1 or BRCA2 genes. PARTICPANTS AND METHODS: Men enrolled in the IMPACT study were invited to complete a questionnaire at collaborating sites prior to each annual screening visit. The questionnaire included sociodemographic characteristics and the following measures: the Hospital Anxiety and Depression Scale (HADS), Impact of Event Scale (IES), 36-item short-form health survey (SF-36), Memorial Anxiety Scale for Prostate Cancer, Cancer Worry Scale-Revised, risk perception and knowledge. The results of the baseline questionnaire are presented. RESULTS: A total of 432 men completed questionnaires: 98 and 160 had mutations in BRCA1 and BRCA2 genes, respectively, and 174 were controls (familial mutation negative). Participants' perception of PCa risk was influenced by genetic status. Knowledge levels were high and unrelated to genetic status. Mean scores for the HADS and SF-36 were within reported general population norms and mean IES scores were within normal range. IES mean intrusion and avoidance scores were significantly higher in BRCA1/BRCA2 carriers than in controls and were higher in men with increased PCa risk perception. At the multivariate level, risk perception contributed more significantly to variance in IES scores than genetic status. CONCLUSION: This is the first study to report the psychosocial profile of men with BRCA1/BRCA2 mutations undergoing PCa screening. No clinically concerning levels of general or cancer-specific distress or poor quality of life were detected in the cohort as a whole. A small subset of participants reported higher levels of distress, suggesting the need for healthcare professionals offering PCa screening to identify these risk factors and offer additional information and support to men seeking PCa screening
Multiple novel prostate cancer susceptibility signals identified by fine-mapping of known risk loci among Europeans
Genome-wide association studies (GWAS) have identified numerous common prostate cancer (PrCa) susceptibility loci. We have
fine-mapped 64 GWAS regions known at the conclusion of the iCOGS study using large-scale genotyping and imputation in
25 723 PrCa cases and 26 274 controls of European ancestry. We detected evidence for multiple independent signals at 16
regions, 12 of which contained additional newly identified significant associations. A single signal comprising a spectrum of
correlated variation was observed at 39 regions; 35 of which are now described by a novel more significantly associated lead SNP,
while the originally reported variant remained as the lead SNP only in 4 regions. We also confirmed two association signals in
Europeans that had been previously reported only in East-Asian GWAS. Based on statistical evidence and linkage disequilibrium
(LD) structure, we have curated and narrowed down the list of the most likely candidate causal variants for each region.
Functional annotation using data from ENCODE filtered for PrCa cell lines and eQTL analysis demonstrated significant
enrichment for overlap with bio-features within this set. By incorporating the novel risk variants identified here alongside the
refined data for existing association signals, we estimate that these loci now explain ∼38.9% of the familial relative risk of PrCa,
an 8.9% improvement over the previously reported GWAS tag SNPs. This suggests that a significant fraction of the heritability of
PrCa may have been hidden during the discovery phase of GWAS, in particular due to the presence of multiple independent
signals within the same regio
A view from the outside: some thoughts on the research priorities for Mesolithic and Neolithic lithic studies in Britain and Ireland
The anthropology of hunter-gatherers: key themes for archaeologists
This book provides a basic introduction to key debates in the study of hunter-gatherers, specifically from an anthropological perspective, but designed for an archaeological audience. Hunter-gatherers have been the focus of intense anthropological research and discussion over the last hundred years, and as such there is an enormous literature on communities all over the world. Yet, among the diverse range of peoples studied, there are a number of recurrent themes, including not only the way in which people make a living (hunting, gathering and fishing) but also striking similarities in other areas of life such as belief systems and social organisation. These themes are described and then explored through archaeological case-studies. The overarching theme throughout the volume is the use of ethnographic analogy, and how archaeologists should be critical in its use
Virtual reality, visual envelopes, and characterizing landscape
In this chapter, I consider how archaeologists have used visual representations to accompany discus-sions of landscape. In particular, I focus on recent “postprocessual” considerations of landscape and the forms of representation that have been used to illustrate both theoretical points and landscape case studies. I go on to consider how new virtual methods of representation offer a way forward for landscape studies
'Very real shared traditions'? Thinking about similarity and difference in the construction and use of Clyde cairns in the Western Scottish Neolithic
In this paper, evidence for Neolithic activity in the western mainland of Scotland is explored, with a particular emphasis on megalithic monumentality and the archaeology of Argyll. This is a much under-studied area, and as the author notes, has as much if not more in common with the Neolithic or Ireland than of eastern Scotland. The paper draws on the author’s extensive fieldwork in the area including work on Bargrennan tombs and excavations at Blasthill. Monumentality, material culture and other aspects of Neolithic life in the western fringes of Scotland are explored in this important contribution to Neolithic studies in the Irish Sea zone
