Reliability and validity of the Daily Cognitive–Communication and Sleep Profile: a new instrument for monitoring sleep, wakefulness and daytime function
Authors: Fung Christina Hoi Ling , Nguyen Michelle , Moineddin Rahim , Colantonio Angela , Wiseman‐Hakes Catherine
Published: February 2014

The Daily Cognitive Communicative and Sleep Profile (DCCASP) is a seven‐item instrument that captures daily subjective sleep quality, perceived mood, cognitive, and communication functions. The objective of this study was to evaluate the reliability and validity of the DCCASP. The DCCASP was self‐administered daily to a convenience sample of young adults (n = 54) for two two‐week blocks, interspersed with a two‐week rest period. Afterwards, participants completed the Pittsburgh Sleep Quality Index (PSQI). Internal consistency and criterion validity were calculated by Cronbach's α coefficient, Concordance Correlation Coefficient (CCC), and Spearman rank (rs) correlation coefficient, respectively. Results indicated high internal consistency (Cronbach‐s α = 0.864−0.938) among mean ratings of sleep quality on the DCCASP. There were significant correlations between mean ratings of sleep quality and all domains (rs=0.38–0.55, p<0.0001). Criterion validity was established between mean sleep quality ratings on the DCCASP and PSQI (rs=0.40, p<0.001). The DCCASP is a reliable and valid self‐report instrument to monitor daily sleep quality and perceived mood, cognitive, and communication functions over time, amongst a normative sample of young adults. Further studies on its psychometric properties are necessary to clarify its utility in a clinical population. Copyright © 2014 John Wiley & Sons, Ltd.
An anatomically realistic temperature phantom for radiofrequency heating measurements
Authors: Graedel Nadine N. , Polimeni Jonathan R. , Guerin Bastien , Gagoski Borjan , Wald Lawrence L.
Published: February 2014

Purpose

An anthropomorphic phantom with realistic electrical properties allows for a more accurate reproduction of tissue current patterns during excitation. A temperature map can then probe the worst‐case heating expected in the unperfused case. We describe an anatomically realistic human head phantom that allows rapid three‐dimensional (3D) temperature mapping at 7T.

Methods

The phantom was based on hand‐labeled anatomical imaging data and consists of four compartments matching the corresponding human tissues in geometry and electrical properties. The increases in temperature resulting from radiofrequency excitation were measured with MR thermometry using a temperature‐sensitive contrast agent (TmDOTMA−) validated by direct fiber optic temperature measurements.

Results

Acquisition of 3D temperature maps of the full phantom with a temperature accuracy better than 0.1°C was achieved with an isotropic resolution of 5 mm and acquisition times of 2–4 minutes.

Conclusion

Our results demonstrate the feasibility of constructing anatomically realistic phantoms with complex geometries incorporating the ability to measure accurate temperature maps in the phantom. The anthropomorphic temperature phantom is expected to provide a useful tool for the evaluation of the heating effects of both conventional and parallel transmit pulses and help validate electromagnetic and temperature simulations.

Authors: Mukund Kavitha , Mathewson Margie , Minamoto Viviane , Ward Samuel R. , Subramaniam Shankar , Lieber Richard L.
Published: February 2014

Introduction: This study provides global transcriptomic profiling and analysis of botulinum toxin A (BoNT‐A)–treated muscle over a 1‐year period. Methods: Microarray analysis was performed on rat tibialis anterior muscles from 4 groups (n = 4/group) at 1, 4, 12, and 52 weeks after BoNT‐A injection compared with saline‐injected rats at 12 weeks. Results: Dramatic transcriptional adaptation occurred at 1 week with a paradoxical increase in expression of slow and immature isoforms, activation of genes in competing pathways of repair and atrophy, impaired mitochondrial biogenesis, and increased metal ion imbalance. Adaptations of the basal lamina and fibrillar extracellular matrix (ECM) occurred by 4 weeks. The muscle transcriptome returned to its unperturbed state 12 weeks after injection. Conclusions: Acute transcriptional adaptations resemble denervated muscle with some subtle differences, but resolved more quickly compared with denervation. Overall, gene expression across time correlates with the generally accepted BoNT‐A time course and suggests that the direct action of BoNT‐A in skeletal muscle is relatively rapid.

Published: February 2014

New data regarding the white shark (Carcharodon carcharias) at the archaeological complex Huaca Pucllana (200–700 ad) are presented on the basis of the recent discovery of teeth in ritual offering features. Previous information of this species from fossil, archaeological and modern records is reviewed. The use of the white sharks as an El Niño indicator is rejected. Past and present white shark distribution in the South East Pacific is reviewed, and the extermination of pinniped colonies as a factor in the poor modern record is discussed.

Authors: Green Angela K. , Jacques Paul F. , Rogers Gail , Fox Caroline S. , Meigs James B. , McKeown Nicola M.
Published: February 2014

Objective

The purpose of this study was to examine the relationship between usual sugar‐sweetened beverage (SSB) consumption and prevalence of abnormal metabolic health across body mass index (BMI) categories.

Methods

The metabolic health of 6,842 non‐diabetic adults was classified using cross‐sectional data from the Framingham Heart Study Offspring (1998‐2001) and Third Generation (2002‐2005) cohorts. Adults were classified as normal weight, overweight or obese and, within these categories, metabolic health was defined based on five criteria—hypertension, elevated fasting glucose, elevated triglycerides, low HDL cholesterol, and insulin resistance. Individuals without metabolic abnormalities were considered metabolically healthy. Logistic regression was used to examine the associations between categories of SSB consumption and risk of metabolic health after stratification by BMI.

Results

Comparing the highest category of SSB consumers (median of 7 SSB per week) to the lowest category (non‐consumers), odds ratios (95% confidence intervals) for metabolically abnormal phenotypes, compared to the metabolically normal, were 1.9 (1.1‐3.4) among the obese, 2.0 (1.4‐2.9) among the overweight, and 1.9 (1.4‐2.6) among the normal weight individuals.

Conclusions

In this cross‐sectional analysis, it is observed that, irrespective of weight status, consumers of SSB were more likely to display metabolic abnormalities compared to non‐consumers in a dose‐dependent manner.
Dielectric properties of poly(vinylidene fluoride) composites based on Bucky gels of carbon nanotubes with ionic liquids
Authors: Chen Guang‐Xin , Zhang Shicheng , Zhou Zheng , Li Qifang
Published: February 2014

“Bucky gels” of carbon nanotubes were successfully prepared by grinding multi‐walled carbon nanotubes (MWNTs) and ionic liquids (ILs) for several hours. A series of poly(vinylidene fluoride) (PVDF) composites with Bucky gels was obtained through simple melt compounding. The Raman spectrum showed significant interaction among the ILs, MWNTs, and PVDF. The dielectric behavior of the PVDF composites based on unmodified and IL‐modified MWNTs was studied from 40 Hz to 30 MHz. The addition of ILs significantly enhanced the dielectric property of the PVDF/IL/MWNT ternary composites, which was much higher than that of the sum of PVDF/IL and PVDF/MWNT binary composites. The SEM results revealed that both MWNTs and ILs uniformly dispersed throughout the PVDF/IL/MWNT composites because of the strong interaction between them. The DSC and XRD results showed that the addition of ILs in the composites changed the crystallinity and crystal form of the PVDF. POLYM. COMPOS., 36:94–101, 2015. © 2014 Society of Plastics Engineers
Mechanical and water binding properties of carboxymethyl cellulose/multiwalled carbon nanotube nanocomposites
Authors: Dadfar Seyed Mohammad Mahdi , Kavoosi Gholamreza
Published: February 2014

Carboxymethyl cellulose (CMC) composite films were prepared from CMC solutions (2% w/v) containing multiwalled carbon nanotubes (MWCNT) as nanofiller and glycerol (25% w/w CMC) as plasticizer. Tensile strength, elongation at break (EAB), young's modulus, water solubility, water swelling, water uptake, and water vapor permeability (WVP) for CMC films were 27.5 ± 2.5 MPa, 11.2 ± 0.8%, 198 ± 18 MPa, 57 ± 1.5%, 738 ± 25%, 124 ± 4%, and 0.55 ± 0.036 g.mm/m2.kPa.h, respectively. By increasing the relative humidity from 11.4 to 85.5%, the moisture absorption (MA) of CMC films was increased from 4 to 38%. Incorporation of MWCNT into the matrix caused a significant increase in the tensile strength, decrease in EAB, increase in young's modulus, decrease in water solubility, decrease in water swelling, decrease in water uptake, and decrease in MA. CMC/MWCNT films containing 1% MWCNT showed the lowest WVP. Scanning electron microscopy showed a good dispersion of MWCNT in the CMC matrix. CMC/MWCNT films containing >1% MWCNT showed significant antibacterial activities against both Gram‐positive and Gram‐negative bacteria in a dose‐dependent manner. Thus, good mechanical properties and water resistance along with strong antibacterial activities make CMC films grafted with MWCNT as a suitable packaging material. POLYM.

Dynamic mechanical properties and correlation with dynamic fragility of sisal reinforced composites
Authors: Ornaghi Heitor Luiz , Zattera Ademir José , Amico Sandro Campos
Published: February 2014

In this study, the reinforcement effect in sisal/polyester composites containing distinct reinforcement content was studied ranging from fragile to strong classification. The results indicate that the reduced storage modulus changes steadily, and the loss modulus and the tan δ peak are broader for composites containing more fiber (dynamically strong composites). As more fiber was incorporated in the resin, lower peak height for the tan delta curve was obtained, which may be indicative of lower energy dissipation due to a greater relative amount of interface. Also, the use of reduced dynamic mechanical curves (similar to dynamic fragility) is an alternative to facilitate the study of the material behavior. POLYM.

Authors: Hashmi S.A.R. , Rajput Rajendra Singh , Naik Ajay , Chand Navin , Singh R.K.
Published: February 2014

An experimental study was conducted to investigate joint efficiency of both, butt, and lap joints of sisal CSM reinforced polymer composites. The thermoplastics, HDPE, and polypropylene (PP) were used separately as matrices in composites. Sisal‐HDPE composites exhibited excellent improvement in tensile strength that reached up to 47.5 MPa at 30 phr loading of sisal CSM as compared with 17.7 MPa of HDPE. Significant improvement in HDT was also observed that increased from 60.2 to 75°C on 0 to 30 phr reinforcement of sisal CSM in HDPE. Similar improvement was noticed with PP where in HDT improved from 69 to 87.6°C on incorporation of 0 to 30 phr sisal CSM. Hot tool welding process was employed for joining the composite materials. The joint efficiency of butt joint of HDPE was observed as 30%. It varied from 48 to 59% for lap joints of different sizes. The joint efficiencies of 20 mm lap joints of different compositions were observed as 59, 98, 75, and 58% in 0, 10, 20, and 30 phr Sisal CSM‐HDPE composites, respectively. Welded joint strengthening is attributed to partial reinforcement of interface that occurs during softening of matrix material which allowed spring back of originally pressed fibers followed by their repositioning in the welded part.

Recent advances and potential applications of the photo‐induced macroscopic response of self‐assembled azopolymer in aqueous media
Authors: Bai Yu , Hu Jinhua , Shen Wenming , Hu Xiao
Published: February 2014

This mini‐review highlights issues related to the photo‐triggered macroscopic response of azopolymer in supramolecular hydrogel and polymer vesicles. Cyclodextrin (CD) can form an inclusion complex with trans‐azobenzene while cis‐azobenzene is expelled out of the CD's cavity. This photo‐reversible supramolecular host − guest interaction is used to trigger sol − gel transitions and to induce macroscopic assembly. When substituted azobenzene is located at chain ends of linear polyethylene glycol, monodisperse vesicles are formed exhibiting a photo‐induced pulsating behavior. The macroscopic phase transition and assembly or pulsating behavior of azopolymers can be expected to have potential applications as smart biomedical materials. © 2014 Society of Chemical Industry

Published: February 2014

The main goal of this work is to evaluate some differential protein species in transgenic (T) and nontransgenic (NT) Arabidopsis thaliana plants after their cultivation in the presence or absence of sodium selenite. The transgenic line was obtained through insertion of CaMV 35S controlling nptII gene. Comparative proteomics through 2D‐DIGE is carried out in four different groups (NT × T; NT × Se‐NT (where Se is selenium); Se‐NT × Se‐T, and T × Se‐T). Although no differential proteins are achieved in the T × Se‐T group, for the others, 68 differential proteins (by applying a regulation factor ≥1.5) are achieved, and 27 of them accurately characterized by ESI‐MS/MS. These proteins are classified into metabolism, energy, signal transduction, disease/defense categories, and some of them are involved in the glycolysis pathway—Photosystems I and II and ROS combat. Additionally, laser ablation imaging is used for evaluating the Se and sulfur distribution in leaves of different groups, corroborating some results obtained and related to proteins involved in the glycolysis pathway. From these results, it is possible to conclude that the genetic modification also confers to the plant resistance to oxidative stress.
Structural insight into the dimerization of human protein disulfide isomerase
Authors: Bastos‐Aristizabal Sara , Kozlov Guennadi , Gehring Kalle
Published: February 2014

Protein disulfide isomerases (PDIs) are responsible for catalyzing the proper oxidation and isomerization of disulfide bonds of newly synthesized proteins in the endoplasmic reticulum (ER). Here, it is shown that human PDI (PDIA1) dimerizes in vivo and proposed that the dimerization of PDI has physiological relevance by autoregulating its activity. The crystal structure of the dimeric form of noncatalytic bb′ domains of human PDIA1 determined to 2.3 Å resolution revealed that the formation of dimers occludes the substrate binding site and may function as a mechanism to regulate PDI activity in the ER.
Conservation of artists' acrylic emulsion paints: XPS, NEXAFS and ATR‐FTIR studies of wet cleaning methods
Authors: Willneff E. A. , Ormsby B. A. , Stevens J. S. , Jaye C. , Fischer D. A. , Schroeder S. L. M.
Published: February 2014

Works of art prepared with acrylic emulsion paints became commercially available in the 1960s. It is increasingly necessary to undertake and optimise cleaning and preventative conservation treatments to ensure their longevity. Model artists' acrylic paint films covered with artificial soiling were thus prepared on a canvas support and exposed to a variety of wet cleaning treatments based on aqueous or hydrocarbon solvent systems. This included some with additives such as chelating agents and/or surfactants, and microemulsion systems made specifically for conservation practice. The impact of cleaning (soiling removal) on the paint film surface was examined visually and correlated with results of attenuated total reflection Fourier transform infrared, XPS and near‐edge X‐ray absorption fine structure analyses – three spectroscopic techniques with increasing surface sensitivity ranging from approximately − 1000, 10 and 5 nm, respectively. Visual analysis established the relative cleaning efficacy of the wet cleaning treatments in line with previous results. X‐ray spectroscopy analysis provided significant additional findings, including evidence for (i) surfactant extraction following aqueous swabbing, (ii) modifications to pigment following cleaning and (iii) cleaning system residues. © 2014 The Authors.

The Use of Biologic DMARDS Identifies Rheumatoid Arthritis Patients with More Optimistic Expectations of Total Knee Arthroplasty
Authors: Goodman Susan M. , Mandl Lisa A. , Figgie Mark , Johnson Beverly K. , Alexiades Michael , Ghomrawi Hassan
Published: February 2014

Background

Preoperative expectations of total knee arthroplasty (TKA) correlate with postsurgical satisfaction, and are linked to outcomes. Rheumatoid arthritis (RA), and other chronic diseases, may lower expectations, although new biologic medications have greatly enhanced patients’ quality of life.

Questions/Purposes

The purpose of this study is to compare preoperative expectations of RA to those of matched osteoarthritis (OA) patients undergoing TKA, and examine the subset of RA on biologic DMARD therapy.

Methods

For a cross-sectional study, RA and OA identified from an institutional TKA registry were matched on age, sex, prior TKA, and preoperative function. Expectations were measured using the Hospital for Special Surgery (HSS) Knee Expectations Survey. Expectations and quality of life measures were assessed preoperatively and scores were compared between RA and OA.

Results

One hundred fourteen RA cases, 46.5% on biologics, were matched to 228 OA cases. The average expectations score was not significantly lower for RA compared to OA (72.9 ± 20.7 vs. 77.2 ± 18.3, p = 0.040. RA on biologics had expectations similar to OA (total expectation score 76.3 ± 18.1 vs. 77.4 ± 17.4, p = 0.71), while RA not on biologics had expectations that were significantly lower (69.9 ± 22.4 vs. 77.1 ± 19.0, p = 0.03).

Conclusion

Use of biologics in RA patients was associated with higher expectations, similar to those of OA patients, but the effect on outcomes is not known. Further studies should assess the effect of higher expectations in RA patients on outcomes.
Arm Ache
Authors: Chabok Hosein Ahmadzadeh , Ring David
Published: February 2014

Both patients and providers hope for better management strategies for nonspecific activity-related upper limb pain (herein referred to as “arm ache”). The next innovation in the care of arm ache may arise from the strong evidence that mood, coping strategies (e.g., catastrophic thinking), and heightened illness concern—all very responsive to treatment with cognitive behavioral therapy—account for a large percentage of the variation in symptom intensity and magnitude of disability. This focus on treatments to reduce symptoms and disability represents a change in culture for patients and providers, both of whom are accustomed to the biomedical framework that anticipates a direct correspondence between illness (the state of being unwell) and disease (pathophysiology). Not all patients are ready for such an approach, but as a first step health providers can prioritize empathy; remain mindful that words, illness concepts, and treatments can reinforce ineffective coping strategies; and encourage curiosity about the human illness experience.
Adherence to Therapy after Flexor Tendon Surgery at a Level 1 Trauma Center
Authors: Toker Serdar , Oak Nikhil , Williams Allison , Ipaktchi Kyros , Ozer Kagan
Published: February 2014

Background

Nonadherence to postoperative therapy protocols can adversely affect the outcome after flexor tendon surgery. In this study, we hypothesize that patients with partial or no insurance coverage for their aftercare are less likely to attend postoperative therapy sessions and have a higher incidence of a poorer outcome than those who have full insurance coverage.

Methods

We analyzed 159 patients with flexor tendon injuries at a level 1 trauma center. Demographic variables along with the clinical outcome data were collected and cross-tabulated. Associations among descriptive and clinical variables were assessed using Fisher's Exact tests and chi-square analyses. Comparisons for continuous variables were performed using the Kruskal-Wallis Test.

Results

Eighteen patients (11.3 %) had an injury in zone 1, followed by 68 (42.8 %) in zone 2, 15 (9.4 %) in zone 3, 9 (5.7 %) in zone 4, 38 (23.9 %) in zone 5, and 11 (6.9 %) in zone 6. Patients completed 8.2 therapy sessions on average. Patients had state assistance program (40.3 %), private insurance (35.2 %), Medicaid/Medicare (11.3 %), worker's compensation (8.8 %) insurance, or paid themselves (13.2 %). Fifty-three (33.3 %) patients had excellent outcomes, 46 (29 %) had good, 40 (25 %) had fair, and 20 (12.5 %) had a poor outcome. Patients responsible to pay for their aftercare were significantly less likely to be adherent to therapy and had poorer outcomes than those with full coverage.

Conclusion

Patients responsible for the pay of their postoperative rehabilitation are less likely to participate in therapy and may be at a higher risk of having a poor outcome.

Published: February 2014

Epidural morphine in patient‐controlled analgesia regimens controls postoperative pain well but easily induces pruritus and other epidural morphine‐related side effects. With 90 pregnant American Society of Anesthesiologists physical status II females scheduled for elective cesarean delivery, the present study was designed to evaluate the efficacy and safety profile of patient‐controlled antipruritus (PCP) use of intravenous nalbuphine‐based regimens for attenuation of postoperative pruritus and related side effects in combination with epidural morphine patient‐controlled analgesia with regard to the quality of postoperative pain management. Patients were randomly assigned to two nalbuphine groups (5 μg/kg/hour, Group N5 or 10 μg/kg/hour, Group N10) and bolus dose of 1.6 μg/kg for PCP or the control (normal saline) group. Comparable visual analog scale scores for rest pain at each measured time interval among the three groups demonstrated that adequate pain relief was offered; however, the cumulative dose of nalbuphine administered to the patients in Group N10 attenuated the analgesic effect of epidural morphine in moving pain at POh24 only. Fewer episodes and milder severity of pruritus were observed in patients in Groups N5 and N10 at all postoperative time intervals. Epidural morphine provided good postoperative pain relief but with incommodious side effects. In addition, intravenous nalbuphine not only attenuated the incidence of pruritus but also decreased total morphine consumption. In conclusion, intravenous administration of low‐dose nalbuphine (5 μg/kg/hour) for PCP maintained analgesia produced by epidural morphine and offered low pruritus incidence.
Mechanical Chest Compressions in an Avalanche Victim With Cardiac Arrest: An Option for Extreme Mountain Rescue Operations

Published: February 2014

Mountain rescue operations often present helicopter emergency medical service crews with unique challenges. One of the most challenging problems is the prehospital care of cardiac arrest patients during evacuation and transport. In this paper we outline a case in which we successfully performed a cardiopulmonary resuscitation of an avalanche victim. A mechanical chest-compression device proved to be a good way of minimizing hands-off time and providing high-quality chest compressions while the patient was evacuated from the site of the accident.
MULTIPLICATIVE SUB-HODGE STRUCTURES OF CONJUGATE VARIETIES
Authors: SCHREIEDER STEFAN
Published: February 2014

For any subfield $K\subseteq \mathbb{C}$, not contained in an imaginary quadratic extension of $\mathbb{Q}$, we construct conjugate varieties whose algebras of $K$-rational ($p,p$)-classes are not isomorphic. This compares to the Hodge conjecture which predicts isomorphisms when $K$ is contained in an imaginary quadratic extension of $\mathbb{Q}$; additionally, it shows that the complex Hodge structure on the complex cohomology algebra is not invariant under the Aut($\mathbb{C}$)-action on varieties. In our proofs, we find simply connected conjugate varieties whose multilinear intersection forms on $H^{2}(-,\mathbb{R})$ are not (weakly) isomorphic. Using these, we detect nonhomeomorphic conjugate varieties for any fundamental group and in any birational equivalence class of dimension $\geq $10.
A Not-yet-postcolonial Peninsula: Rewriting Spaces of Violence, Division and Diaspora
Authors: Watson Jini Kim
Published: February 2014

In his controversial 2001 novel,The Guest(Sonnim), Hwang Sok-yong tells the story of elderly Korean American Ryu Yosŏp, who embarks on a journey back to his childhood home in Hwanghae province, now North Korea. At once a spatial, temporal, and psychological return, the novel revisits the early years of the Korean War to unveil the truth behind one of the war’s most horrific crimes: the slaughter of 35,000 Korean civilians in the Shinch’on massacre of 1950. In particular, Hwang examines the arrival of the two “guests” of the title—Christianity and Marxism—during the colonial period and their subsequent role in the violence of Shinch’on. By making visible forms of political agency achieved through the assimilation of these two guests, the novel complicates the ideological binaries that appear to have arrested decolonization of the Korean peninsula. Watson’s article reveals how Hwang’s experimental, multivocal narrative structure rewrites usual historical accounts of the Korean War and division by attending to the spatialized production of regions, nation, state, and diaspora. It offers a rethinking of the congealed ideologies, stories, desires, and topologies of this not-yet-postcolonial peninsular.
Strategies for anti-coccidial prophylaxis
Authors: WITCOMBE DAVID M. , SMITH NICHOLAS C.
Published: February 2014

Coccidiosis, a serious disease resulting from infection with parasitic protozoa of the genusEimeria, causes significant economic losses to the poultry industry, where intensive rearing facilitates transmission of infectious oocysts via the fecal/oral route. Current control relies primarily on prophylactic drugs in feed but, whilst cost effective, the rise of drug resistance and public demands for residue-free meat has encouraged development of alternative control strategies. Chickens that recover from infection withEimeriadevelop solid immunity that is directed against the early asexual stages of the parasite life cycle. This has allowed development of a number of vaccines that utilize deliberate infection with controlled doses of virulent oocysts or reproductively attenuated lines ofEimeria.The latter are immunogenic but non-pathogenic. The realization that both prophylactic drugs and attenuated vaccines control but do not eradicate infection withEimeriaencouraged development of a vaccine based upon maternal immunity. Laying hens exposed toEimeriaare able to transfer protective antibodies to hatchlings via egg yolks and these antibodies have been used to identify parasite proteins that are conserved across the genus. When delivered maternally, these provide an economical means of preventing coccidiosis, offering immediate protection to newly hatched chicks.
Houses, Lifecycles and Deposition on Middle Bronze Age Settlements in Southern England
Authors: Brück Joanna
Published: February 2014

This paper explores how the lifecycles of Middle Bronze Age settlements were intimately related at both a practical and metaphorical level to the lifecycles of their inhabitants. Many settlements of this date appear to have been single-generational sites. Building sequences and other changes in the use of settlement space can be understood within a framework that explores how the demographic, social, and economic circumstances of a site's occupants changed over time. However, the lifecycle of the settlement was not only related to that of its occupants in practical terms; each was also a symbolic representation of the other. For example, such acts as the deposition of whole quernstones or animal burials in pits and ditches may have been carried out at critical points in the lifecycle of a settlement, its structures, and its inhabitants. The notion that settlements had lifecycles introduces the possibility of anthropomorphic symbolism in house architecture, a suggestion that may help to explain the presence of a standardised house form during the Middle Bronze Age. Yet, despite the formality of the architecture, there was considerable diversity in how space was actually used within the round-house. Likewise, variability in other aspects of these settlement sites suggests that, although cultural ideals may have existed, in practice the developmental cycle of each household group depended on a particular set of social and material circumstances as well as on household members' commitment to communal tradition.
The Hinxton Rings – A Late Iron Age Cemetery at Hinxton, Cambridgeshire, with a Reconsideration of Northern Aylesford-Swarling distributions

Published: February 2014

The excavation of a 1st century BC cremation cemetery having ring-ditch surrounded interments is reported. One of its two richly accompanied burials included an unparalleled drapery-cast stud/knob – an extraordinary object found within a cemetery with uniquely delineated graves. Given its location on the northern fringe of the distribution of Aylesford-Swarling cremation burials, the site prompts questions of core/periphery interrelationships, regionally and group definition.
Resharpening and Recycling of Flint Bifacial Tools from the Southern Levant Neolithic and Chalcolithic
Authors: Barkai Ran
Published: February 2014

This paper attempts at reconstructing the life cycle of flint bifacial tools in two major technological trajectories, each aimed at a different end. It is focused on discarded polished flint bifacial tools (axe, adze, chisel) and bifacial polished debitage items found in Neolithic and Chalcolithic sites (9th–6th millennium BP) from the Southern Levant.

Recent studies of Holocene flint assemblages revealed special types of debitage items such as blades, flakes, cores and core trimming elements, all bearing traces of polish. The discovery of these polished debitage items in Levantine sites enabled a study of bifacial tool resharpening and recycling techniques, emphasising the exceptional attention paid to this tool category. Since polished bifacial tools appear in many old world Holocene archaeological contexts, the data and interpretation presented in this study have implications far beyond the Southern Levant and could relate to universal technological properties of flint axes and other bifacial tools.
Chronology of Greece and South-east Europe in the Final Neolithic and Early Bronze Age
Authors: Johnson Mats
Published: February 2014

Final Neolithic to Early Bronze Age chronology in Greece remains obscure due to a lack of stratified deposits and radiocarbon dates. In this paper the Greek evidence is considered in the light of typological parallels, stratigraphic sequences, and the larger series of radiocarbon dates available from the south-east European cultures, and a tentative chronology for Greece and south-east Europe is presented. The evidence does not support the earlier notion of an overlap between the Thessalian Rachmani period and the Early Helladic period of southern Greece, but rather suggests that Rachmani is essentially contemporary with the southern Greek Final Neolithic. The Final Neolithic–Early Bronze Age transition in southern Greece shows affinities to Petromagoula in Thessaly and the Boleráz culture of Europe. Several radiocarbon dates place the Boleráz period in the early 5th millennium BP, suggesting that dates from FN–EBA transitional contexts in Greece may, in the future, help to fill the existing early 5th millennium gap in the Greek radiocarbon date series.
The Stone Knight, the Sphinx and the Hare: New Aspects of Early Figural Celtic Art
Authors: Frey Otto-Herman
Published: February 2014

The paper re-examines arguments concerning the early development of early Celtic (La Tène A) art and its relations with the Mediterranean world. Taking as a focus the recent spectacular discoveries below the hillfort of the Glauberg north-east of Frankfurt, the Celtic approaches to representations of the human form are analysed and the complex question of meaning and the relationship of early Celtic art to contemporary belief systems discussed. As a brief coda, the striking changes which took place in many parts of the early Celtic world after c. 400 BC are referred to in the context of the major population movements of the time, notably those which brought settlers from north of the Alps to Italy.
On the Significance of Acheulean Biface Variability in Southern Britain
Authors: White Mark J.
Published: February 2014

The significance of morphological variation in Acheulean bifaces has been a central issue in Palaeolithic research for well over a century. For much of that period interpretation has been dominated by culture-historical models and it is only in the past 20 years that other explanatory factors have received adequate attention. This paper examines the combined role of several of these factors – namely raw materials, reduction intensity, and function – on biface variability in the British Isles, with special reference to the two major shaped-based ‘tradition’ devised by Roe (1967; 1968). First-hand examination of bifaces from 19 assemblages suggests that final biface shape depends largely on the dimensions of the original raw materials and the technofunctional strategies designed to deal with them. Through these observations a new model is generated and tested. This suggests that the patterning in the British Acheulean simply reflects the nature of the resources available at a site and the hominid procurement and technological strategies used to exploit them. According to this model, well-worked ovates with all-round edges were preferentially produced wherever raw materials were large and robust enough to frequently support intensive reduction procedures, usually when obtained from primary flint sources. Assemblages characterised by partially-edged, moderately-reduced pointed forms were only manufactured when smaller, narrower blanks, that imposed restrictions on human technological actions regarding the location and extent of working, were exploited. Such blanks were usually obtained from a secondary flint source, such as river gravel. Thus, Roe's pointed and ovate ‘traditions’ are seen not as the products of different biface making populations, but as the same broad populations coping with the exigencies of a heterogeneous environment, using different resources in an adaptive, flexible manner.
Doggerland: a Speculative Survey
Authors: Coles B.J.
Published: February 2014

Archaeologists tend to refer to the land that once existed between Britain and the continent as a landbridge. It was, however, a landscape as habitable as neighbouring regions, and here called Doggerland to emphasise its availability for settlement by prehistoric peoples. Evidence from the Geological Surveys undertaken by countries bordering the North Sea Basin, together with allied research, is drawn together to provide an overview of the possibilities. A range of interacting geological processes implies that the present-day relief of the North Sea bed does not provide a sound guide to the relief of the former landscape, nor to the chronology and character of its submergence. A series of maps accompanies the text to provide a speculative reconstruction of the topography, river systems, coastline, vegetation, fauna, and human occupation of Doggerland from the Devensian/Weichselian maximum to the beginnings of the Neolithic.
Long Barrows and Neolithic Elongated Enclosures in Lincolnshire: An Analysis of the Air Photographic Evidence
Authors: Jones Dilwyn
Published: February 2014

The long barrows of Lincolnshire have been the subject of long-term but intermittent interest. One aspect not investigated hitherto is the air photographic evidence for plough-levelled long barrows. Recently completed mapping work in the county by the Aerial Survey section of the Royal Commission on the Historical Monuments of England (RCHME), as part of the National Mapping Programme, has made possible the analysis of the air photographic evidence. This article presents an evaluation of that evidence and considers its significance in terms of the Neolithic of the region.

A comprehensive survey of air photo collections has dramatically increased the number of long barrows known in the county, identifying over 50 examples of levelled sites. The majority are found on the chalk Wolds where the dozen surviving earthwork monuments are located. The distribution of long barrows in the county may now be extended onto the Jurassic Limestone ridge to the west where five examples have been recorded. The Lincolnshire long barrow enclosures have three categories of shape; oval, trapeziform, and oblong. The ditch plan is predominantly full-enclosing, and is found as the distinct form in the eastern region of England. The morphology and dimensions of two sites suggests they may have been a long mortuary enclosure or short cursus.

At Harlaxton in the southern Limestone a long barrow enclosure forms part of an extensive later Neolithic ritual complex which incorporates a multiple pit-alignment as a principal component. The form of the complex appears to be unique and underlines the importance of Harlaxton as an inter-regional link.
The Public Forum and the Space Between: the Materiality of Social Strategy in the Irish Neolithic
Authors: Fraser Shannon Marguerite
Published: February 2014

Framed within an interpretive, humanistic ‘archaeology of inhabitance’, the study explores the means by which a social, intellectual order particular to time and place is embedded within the material universe. Through the mediation of the human body, natural and architectural space is considered to be a medium for the production and reproduction of social relations. The specific materiality of places inhabited in the past is explored in detail, focusing on possibilities for and constraints upon the body and the senses.

The phenomenon of monumentality at the Loughcrew passage tomb cemetery in east-central Ireland is considered in the context of changing narratives of place and biographies of person and landscape. In contrast to many previous studies, the focus is upon engagement with the exterior spaces of the complex: the more frequent and larger-scale involvement of the communal body in these ‘public’ spaces will have played a critical role in the validation of knowledges and claims to authority which a more restricted group will have articulated within the confines of tomb chambers and passages.

The earlier tombs draw out qualities latent within the landscape, placing particular emphasis on prior, natural boundaries. Through time, the regionalisation of the Loughcrew hills acquires increasing architectural definition, by means of which a series of interconnecting spaces emerge at a much more human scale. The latest architectural and spatial developments may well form part of material strategies through which were engendered particular structures of authority carrying the potential for substantially heightened individual prominence within increasingly exclusive kinship solidarities. Ultimately, mediation between the physical and metaphysical elements of existence may be controlled with reference to distinct lines of descent rather than to a more generalised ancestral community. At the same time, the range of hills is gradually transformed from a meaningful locus which conceals within it the human efforts of monumental construction, to a landscape that derives its significance from massive summit cairns visible from considerable distances. This appropriative transformation may be seen as a material strategy which moves communities' conceptions of existence from an integrated, cultural whole in which people and landscape are embedded in each other, towards a vision of individuals and places as increasingly separate and self-contained.
The Changing Provenance of Red Ochre at Puritjarra Rock Shelter, Central Australia: Late Pleistocene to Present
Authors: Smith M. A. , Fankhauser B. , Jercher M.
Published: February 2014

In this paper we apply geochemical sourcing methods to an assemblage of ochre from archaeological excavations at the Puritjarra rock shelter in western central Australia. Our work indicates that the red ochre in Late Pleistocene contexts at this rock shelter is from Karrku, a subterranean ochre mine still worked today by Walbiri people. Archaeological finds at Puritjarra indicate that exploitation of this source of high-grade red ochre had begun by 32,000 BP and has continued without significant interruption since then. Changes since the Late Pleistocene in the type and quantity of red ochre reaching the Puritjarra shelter, from various sources including Karrku, provide means to test current models of regional prehistory in this part of arid Australia and illustrate some of the potential of this approach for regional studies.
Rock Art in Morocco
Authors: Alaoui Fatima-Zohra Sbihi , Searight Susan
Published: February 2014

Rock art in Morocco is widespread and varied, but little known in English-speaking circles. The present paper aims to present a broad outline of this art — almost entirely represented by engravings — as it is known today. A brief survey of past research is given. The distribution of sites is indicated, showing the country to be roughly divided into two areas: the High Atlas mountains and the sub-Saharan regions to the south. Four major groups of engravings are identified, according to theme, technique, and, to a certain extent, style. In the absence of radiocarbon or other datings, the only clues to the chronology of the engravings come from datable material objects or events. None of this art is thought to be older than Neolithic and the most recent engravings certainly date from early historical times. Problems of conservation are discussed, along with measures being taken both to protect the sites and to extend research on this informative aspect of Morocco's past.
Bronze Age ‘Barrows’ and Funerary Rites and Rituals of Cremation
Authors: McKinley Jacqueline I.
Published: February 2014

This paper discusses the evidence for pyre sites, debris, and technology associated with the disposal of cremated human remains in Bronze Age ‘barrows’. The use of the terms such as ‘cremation’, ‘cremation burial’, and ‘cremation-related feature’ are examined. The types of evidence for the remains of cremation-related activities which survive on archaeological sites are described with examples and compared with the results of modern experimental data. It is concluded that a wealth of information may be recovered in relation to the funerary rites and rituals of cremation and that Bronze Age barrows hold a potentially unique position in being able to provide evidence of various aspects of the funerary activity under one ‘mound’. While the archaeological components within different types of cremation-related features are often the same, it is the relationship between the various components within the deposit which have the potential to assist in our understanding of aspects of procedure, rites, and rituals attendant on the disposal of the dead by means of cremation.
Leskernick: Stone Worlds; Alternative Narratives; Nested Landscapes
Authors: Bender Barbara , Hamilton Sue , Tilley Christopher
Published: February 2014

The first season of an on-going project focused on Leskernick Hill, north-west Bodmin Moor, Cornwall, entailed a preliminary settlement survey and limited excavation of a stone row terminal. Leskernick comprises a western and a southern settlement situated on the lower, stony slopes of the hill and including 51 circular stone houses constructed using a variety of building techniques. Walled fields associated with these houses vary in size from 0.25–1 ha and appear to have accreted in a curvilinear fashion from a number of centres. Five smal burial mounds and a cist are associated with the southern settlement, all but one lying around the periphery of the field system. The western settlement includes ‘cairn-like’ piles of stones within and between some houses and some hut circles may have been converted into cairns. The settlements may have been built sequentially but the layout of each adheres to a coherent design suggesting a common broad phase of use. The southern settlement overlooks a stone-free plain containing a ceremonial complex.

The paper presents a narrative account of the work and considers not only the form, function, and chronology of the sites at Leskernick but also seeks to explore the relationships between people and the landscape they inhabit; the prehistoric symbolic continuum from house to field to stone row etc, and to investigate the relationship between archaeology as a discourse on the past and archaeology as practice in the present. It considers how the daily process of excavation generates alternative site histories which are subsequently abandoned, forgotten, perpetuated or transformed.
Italy in Europe in the Early Iron Age
Authors: Sestieri Anna Maria Bietti
Published: February 2014

In the field of European recent prehistory it is generally agreed that, from the Early Orientalising period, Etruria played a central role in long distance trade, also acting as a link between the Aegean and east Mediterranean and trans-Alpine Europe. A widely acknowledged implication is that this primary status of the Etruscans among the indigenous peoples of Italy was a secondary effect of the Greek and Phoenician colonisation in the central Mediterranean. It is the aim of this paper to show that, as early as the Late Bronze Age, Etruria emerged as a complex territorial, political, and economic entity and was able to participate in an interregional network of trade reaching as far as northern Germany and the Aegean. By the beginnings of the Italian Iron Age, this region was organised as a federation of early states, with important extensions in the southern Po plain, along the Adriatic coast, and in Campania.
