Associated bone groups; beyond the Iron Age

As zooarchaeologists move away from the purely economic towards ‘social zooarchaeological’ interpretations, the consideration of articulated/associated faunal remains has become more common-place. This paper presents results from a research project which investigated the nature of these associated bone groups (ABGs). The majority of current work on these deposits has utilised Iron Age material, with ABGs becoming synonymous with certain Iron Age sites, particularly Danebury. This paper moves beyond the Iron Age and discusses their presence on sites from the Neolithic to the Medieval period. It utilises the results of a survey of published sources from southern England and Yorkshire and shows that ABGs are commonly recovered from other periods. Their composition is shown to differ between time periods and regions. Finally in light of the data presented it questions how we should view these deposits

Animal 'Ritual' Killing: from Remains to Meanings

As humans, we interact with our environment and the other species inhabiting it in a variety of ways. Animals not only provide a source of sustenance, but a means for humans to express their social concepts through interaction. The range of human interactions with other species can still be seen in our modern world; such as the use of animal characteristics as metaphors and the humanisation of certain species. Douglas (1990, 33) suggests we think about how animals relate to one another, on the basis of our own relationships. Therefore, human social categories are extended into the animal world. Classical literature can offer examples of this. Aristotle (Politics, 1254b) discussed the similarity between working animals and slaves, which in Roman law were treated together, noting ‘the usefulness of slaves diverges little from that of animals; bodily service for the necessities of life is forthcoming from both’. This entwining of the human and animal worlds was also present in the form of animal sacrifices and Gilhus (2006) has discussed the inventions and developments of such a tradition in depth. Evidence of animal sacrifice is not just limited to the classical world, for example we also have evidence from iconographic depictions from Mesoamerica (Emery 2005), as well as ethnographic observations (Morris 2000, 138). The challenge we face is to use archaeologically recovered faunal data to investigate such social zooarchaeological issues. As the majority of animal remains are of a fragmentary nature, most investigations into social concepts have utilised articulated animal remains. A number of terms have been used when discussing such concepts including animal burials and special animal deposits. However, for this paper the term associated bone group (ABG) has been adopted. Although at first it may appear unimportant, the terminology and language used by archaeologists describing a deposit can greatly influence its interpretation, and importantly, the concepts of other archaeologists. Terms such as ‘special’, to many archaeologists, automatically implies a ritual connotation, similarly ‘burial’, a term utilised mainly for human remains, may conjure images of a ceremonial/ritual event. This is important because within British archaeology the interpretation of these deposits has been stuck in a dichotomy between the ritual and the mundane (Morris 2008a; 2010c). Hill (1995) was also critical of the use of ‘special deposit’ and suggested the term associated/articulated bone group, to remove any connotations. This paper draws on the results of a project that investigated the nature of ABGs in Britain from the Neolithic (c.4000BC) to the end of the late medieval period (c.AD1550). Due to the large time-span it was not possible to investigate every deposit in Britain, therefore just published data from southern England (Dorset, Hampshire and Wiltshire) and Yorkshire was utilised. The results of the project are discussed in detail elsewhere, along with a complete list of the sites recorded (Morris 2008b; 2010c), therefore a brief overview of the major trends will be discussed here. Further consideration will then be given to the interpretation of these deposits and a biographical method based on the actions used to create the ABG will be considered. Finally the paper will use this approach to discuss the presence of ritual animal killings in the British archaeological record

Fish for the city: meta-analysis of archaeological cod remains and the growth of London’s northern trade

The growth of medieval cities in Northern Europe placed new demands on food supply, and led to the import of fish from increasingly distant fishing grounds. Quantitative analysis of cod remains from London provides revealing insight into the changing patterns of supply that can be related to known historical events and circumstances. In particular it identifies a marked increase in imported cod from the thirteenth century AD. That trend continued into the fifteenth and sixteenth centuries, after a short downturn, perhaps attributable to the impact of the Black Death, in the mid fourteenth century. The detailed pattern of fluctuating abundance illustrates the potential of archaeological information that is now available from the high-quality urban excavations conducted in London and similar centres during recent decades

The development of a competence framework for engineering analysis and simulation

Engineering analysis and simulation has always played a significant role in the nuclear sector and its use continues to increase across all branches of industry. To remain competitive in an increasingly global environment and to ensure the safety and reliability of products, companies must prepare effectively for the challenges that new engineering simulation technologies will bring. Concerns surrounding the inappropriate use of simulation by staff without the appropriate competences persist, as analyses become more advanced, increasingly embracing more complex physical phenomena and interactions, often in an effort to model reality more faithfully. These trends and the associated competencies required, emphasize the need for life-long learning and continual staff development. Organisations clearly require a sufficient and ongoing supply of well-qualified engineers and the recently funded EASIT2 project is directly aimed at addressing and managing these issues

Transferring simulation skills from other industries to nuclear

Engineering analysis and simulation has always played a significant role in the nuclear sector and its use continues to increase across all branches of industry. To remain competitive in an increasingly global environment and to ensure the safety and reliability of designs, the nuclear industry must take advantage of the new engineering simulation technologies. Concerns surrounding the inappropriate use of simulation by staff without the appropriate competency persist, as analyses become more advanced, increasingly embracing more complex physical phenomena, often in an effort to model reality more faithfully. Furthermore, the age profile of the skilled staff in the nuclear sector in the UK is such that the skills shortage is likely to increase in future. These trends emphasize the need for life-long learning and continual staff development along with transfer of skills from other industry sectors to the nuclear sector. The nuclear industry has taken some initiatives to address skill shortages through the National Skills Academy for Nuclear and Nuclear Energy Skills Alliance (NESA) but these are mostly focused on manufacturing and R&D skills. The recently completed EU funded EASIT2 project is directly aimed at addressing the engineering analysis and simulation skills. This paper gives a brief overview of the EASIT2 project and its deliverables and points out how it can help the skills issues being faced by the nuclear industry. INTRODUCTIO

"So bigge as bigge may be": tracking size and shape change in domestic livestock in London (AD 1220-1900)

This study presents the analysis of 7966 individual cattle, sheep, pig and domestic hen bone measurements from 105 sites excavated in London dating to the period AD 1220–1900. Multiple episodes of size change are identified, although the speed and timing varies by species. The earliest evidence for size change in cattle and sheep occurs in the early 14th century and may be connected to the need to restock livestock populations following the outbreaks of murrain in the first half of that century. Subsequent size increases in livestock size may have occurred as a combined consequence of agricultural innovations in the wake of the Black Death, the increasing commercialisation of animal farming, as the meat requirements of an expanding London grew, and the rise of the ethic of improvement

Regulation of the neuronal proteasome by Zif268 (Egr1)

Most forms of neuronal plasticity are associated with induction of the transcription factor Zif268 (Egr1/Krox24/NGF-IA). In a genomewide scan, we obtained evidence for potential modulation of proteasome subunit and regulatory genes by Zif268 in neurons, a finding of significance considering emerging evidence that the proteasome modulates synaptic function. Bioinformatic analysis indicated that the candidate proteasome Zif268 target genes had a rich concentration of putative Zif268 binding sites immediately upstream of the transcriptional start sites. Regulation of the mRNAs encoding the psmb9 (Lmp2) and psme2 (PA28�) proteasome subunits, along with the proteasome-regulatory kinase serum/glucocorticoid-regulated kinase (SGK) and the proteasome-associated antigen peptide transporter subunit 1 (Tap1), was confirmed after transfection of a neuronal cell line with Zif268. Conversely, these mRNAs were upregulated in cerebral cortex tissue from Zif268 knock-out mice relative to controls, confirming that Zif268 suppresses their expression in the CNS. Transfected Zif268 reduced the activity of psmb9, SGK, and Tap1 promoter–reporter constructs. Altered psmb9, SGK, and Tap1 mRNA levels were also observed in an in vivo model of neuronal plasticity involving Zif268 induction: the effect of haloperidol administration on striatal gene expression. Consistent with these effects on proteasome gene expression, increased Zif268 expression suppressed proteasome activity, whereas Zif268 knock-out mice exhibited elevated cortical proteasome activity. Our findings reveal that Zif268 regulates the expression of proteasome and related genes in neuronal cells and provide new evidence that altered expression of proteasome activity after Zif268 induction may be a key component of long-lasting CNS plasticity

Robust Classification of Functional and Quantitative Image Data Using Functional Mixed Models

This paper describes how to perform classification of complex, high-dimensional functional data using the functional mixed model (FMM) framework. The FMM relates a functional response to a set of predictors through functional fixed and random effects, which allows it to account for various factors and between-function correlations. Classification is performed through training the model treating class as one of the fixed effects, and then predicting on the test data using posterior predictive probabilities of class. Through a Bayesian scheme, we are able to adjust for factors affecting both the functions and the class designations. While the method we present can be applied to any FMM-based method, we provide details for two specific Bayesian approaches: the Gaussian, wavelet-based functional mixed model (G-WFMM) and the robust, wavelet-based functional mixed model (R-WFMM). Both methods perform modeling in the wavelet space, which yields parsimonious representations for the functions, and can naturally adapt to local features and complex nonstationarities in the functions. The R-WFMM allows potentially heavier tails for features of the functions indexed by particular wavelet coefficients, leading to a down weighting of outliers that makes the method robust to outlying functions or regions of functions. The models are applied to a pancreatic cancer mass spectroscopy data set and compared with some other recently developed functional classification methods

The influence of bovine serum albumin on β-lactoglobulin denaturation, aggregation and gelation

peer-reviewedThe effect of bovine serum albumin (BSA) on the heat-induced denaturation, aggregation and subsequent acid-induced gelation of β-lactoglobulin (β-lg) was investigated in this work. Changes in the denaturation kinetics of β-lg during heating at 78 °C were determined by monitoring the disappearance of the native protein by reverse-phase chromatography. Replacing β-lg with increasing amounts of BSA, while keeping the total protein concentration constant at 5% (w/w), significantly increased the denaturation rate of β-lg from 2.57±0.30×10−3(g L−1)(1−n)s−1 to 5.07±0.72×10−3(g L−1)(1−n)s−1 (β-lg: BSA ratio of 3:1 w/w). The reaction order for β-lg was 1.40±0.09. Partial replacement of β-lg with BSA (β-lg: BSA ratio of 3:1 w/w) significantly increased the reaction order to 1.67±0.13. Heat-induced aggregates between β-lg and BSA were studied by dynamic light scattering, two-dimensional electrophoresis and size exclusion chromatography. The partial replacement of β-lg with BSA significantly changed the gelling properties of the acid-induced gels. A rapid rate of acidification resulted in a significant decrease, while a slow acidification rate resulted in a significant increase in gel strength. Size exclusion chromatography demonstrated that intermolecular disulphide bond formation occurred during both heat-induced denaturation/aggregation and subsequent acid-induced gelation. Results clearly indicate that BSA contributed to the formation of these disulphide bonds.This work was funded under the Food Institutional Research Measure (FIRM) of the National Development Plan 2000-2006.
