Public-sector service provision for older people affected by homelessness in England
Authors: ALDEN SARAH 
Published: November 2015

ABSTRACTThis paper assesses provision for older people affected by homelessness in England, giving regard to research findings, such as those developed through a pathways model, which show that the experiences of this group are qualitatively distinct when compared to younger households. Current conceptualisations of older age held by Local Authority Housing Option Service professionals are considered, alongside factors relating to government policy and resource issues. It was found that some practitioners adopted an age-blind approach when assessing older groups, despite this being contrary to policy guidance on assessing vulnerability in England. Further, services and housing options aimed at older groups were viewed as inadequate due to a mixture of lack of awareness, targeting and resources. It is concluded that assessment of vulnerability based on older age is complex, as whilst gerontological discourse may discourage viewing age as a number, homelessness scholars stress that rooflessness causes poor health conditions consistent with premature ageing. It is therefore asserted that policy makers must focus greater attention to developing suitable provision for older service users and look to incorporate a richer conceptualisation of how older age may impact upon the homelessness experience.
Influence of morphological, chemical and physical leaf traits on food selection of a herbivorous iguana from The Bahamas

Published: November 2015

Abstract:Herbivores are predicted to forage on a variety of plants in order to obtain a nutritionally sufficient diet. Most herbivores, however, forage non-randomly and may be influenced by morphological, chemical and physical traits in their food. We examined the influence of several leaf traits on food selection for the Exuma rock iguana (Cyclura cychlura figginsi). We expected the iguana to prefer leaves with higher nutrient concentration and lower physical defences, such as reflected by high N, P, Ca, K, Mg concentrations and low leaf density and per cent concentrations of cellulose, hemicellulose and lignin, respectively. We quantified selection by examining 30 faecal samples and analysing traits of leaves from the 10 most common plants on the island. Our results showed substantial variability in all measured traits among species but food preference only for less-dense leaves, a good indicator of low leaf toughness. Our results are the first to demonstrate that physical leaf traits can influence food selection in a true herbivorous lizard and offer a basis for future testing.
A connectionist model of the retreat from verb argument structure overgeneralization
Authors: AMBRIDGE BEN , BLYTHING RYAN P. 
Published: November 2015

AbstractA central question in language acquisition is how children build linguistic representations that allow them to generalize verbs from one construction to another (e.g.,The boy gave a present to the girl→The boy gave the girl a present), whilst appropriately constraining those generalizations to avoid non-adultlike errors (e.g.,I said no to her → *I said her no). Although a consensus is emerging that learners solve this problem using both statistical and semantics-based learning procedures (e.g., entrenchment, pre-emption, and semantic verb class formation), there currently exist few – if any – proposals for a learning model that combines these mechanisms. The present study used a connectionist model to test an account that argues for competition between constructions based on (a) verb-in construction frequency, (b) relevance of constructions for the speaker's intended message, and (c) fit between the fine-grained semantic properties of individual verbs and individual constructions. The model was able not only (a) to simulate the overall pattern of overgeneralization-then-retreat, but also (b) to use the semantics of novel verbs to predict their argument structure privileges (just as real learners do), and (c) to predict the pattern of by-verb grammaticality judgements observed in adult studies.

RÉSUMÉLa législation, dans de nombreuses juridictions, nécessite les établissements des soins de longue durée (SLD) d'avoir une infirmière en service 24 heures par jour, 7 jours par semaine. Bien que la recherche considérable existe sur l'intensité SLD de la dotation en personnel infirmier, il n'existe pas de la recherche empirique relative à cette exigence. Notre étude rétrospectif d'observation a comparé des installations en Saskatchewan avec 24/7 RN couverture aux établissements offrant moins de couverture, complétées par divers modèles de dotation des postes de nuit. Les ratios de risque associés à moins de 24/7 couverture RN complété de la dotation infirmière autorisé de nuit, ajusté pour l'intensité de dotation en personnel infirmier et d'autres facteurs de confusion potentiels, étaient de 1,17, IC 95% [0,91, 1,50] et 1.00, IC à 95% [0,72, 1,39], et avec moins de couverture 24/7 RN complété avec soin par aides personnels de nuit, les ratios de risque étaient de 1,46, IC 95% [1,11, 1,91] et 1,11, IC 95% [0,78, 1,58], pour les patients hospitalisés et de visites aux services d'urgence, respectivement. Ces résultats suggèrent que l'utilisation des soins de courte durée peut être influencée négativement par l'absence de la couverture 24/7 RN.

SUMMARYThe first large outbreak of hand, foot, and mouth disease (HFMD) with severe complications primarily caused by enterovirus 71 was reported in Taiwan in 1998. Surveillance of HFMD to evaluate the spread of HFMD with and without infection control policy is needed. We developed a new dynamic epidemic Susceptible-Infected-Recovered (SIR) model to fit the surveillance data on containing valuable information on the severity of HFMD in order to accurately estimate the basic reproductive number (R0) of HFMD. After fitting the empirical data, in conjunction with other relevant parameters extracted from the literature, the estimated transmission coefficients were close to 5 × 10−7 (per day) and the proportion of severe HFMD cases ranged between 0 and 0·0036 (per day). Taking into account the distribution of all parameters considered in our dynamic epidemic model, the R0 computed was 1·37 (95% confidence interval 0·24–5·84), suggesting a higher likelihood of the spread of HFMD if no infection control policy is provided. The isolation strategy against the spread of HFMD not only delayed the epidemic peak with the delayed time ranging from 4 weeks for only 20% isolation to 47 weeks for 100% isolation but also reduced total number of HFMD cases with the percentage of reduction ranging from 1·3% for only 20% isolation to 13·3% for 100% isolation. The proposed model can also be flexible for evaluating the effectiveness of two other possible policies for containing HFMD, quarantine and vaccination (if the vaccine can be developed).

AbstractObjectiveTo investigate biomarkers of nutrition associated with chronic disease absence for an Aboriginal cohort.DesignScreening for nutritional biomarkers was completed at baseline (1995). Evidence of chronic disease (diabetes, CVD, chronic kidney disease or hypertension) was sought from primary health-care clinics, hospitals and death records over 10 years of follow-up. Principal components analysis was used to group baseline nutritional biomarkers and logistic regression modelling used to investigate associations between the principal components and chronic disease absence.SettingThree Central Australian Aboriginal communities.SubjectsAboriginal people (n444, 286 of whom were without chronic disease at baseline) aged 15–82 years.ResultsPrincipal components analysis grouped twelve nutritional biomarkers into four components: ‘lipids’; ‘adiposity’; ‘dietary quality’; and ‘habitus with inverse quality diet’. For the 286 individuals free of chronic disease at baseline, lower adiposity, lower lipids and better dietary quality components were each associated with the absence at follow-up of most chronic diseases examined, with the exception of chronic kidney disease. Low ‘adiposity’ component was associated with absence of diabetes, hypertension and CVD at follow-up. Low ‘lipid’ component was associated with absence of hypertension and CVD, and high ‘dietary quality’ component was associated with absence of CVD at follow-up.ConclusionsLowering or maintenance of the factors related to ‘adiposity’ and ‘lipids’ to healthy thresholds and increasing access to a healthy diet appear useful targets for chronic disease prevention for Aboriginal people in Central Australia.
Observation of Fine Distribution of Minor Dopants in an Erbium-Doped Fiber Core using a Sample Thinning Technique for Field Emission Electron Probe Microanalysis
Authors: Kubo Yugo , Kuramochi Koji 
Published: November 2015

AbstractTo observe the fine distribution of minor aluminum and germanium dopants in the erbium-doped fiber (EDF) core of an optical amplifier, a sample thinning technique was applied for field emission electron probe microanalysis (FE-EPMA) together with wavelength-dispersive X-ray spectrometry. This technique significantly improved the spatial resolution without much degradation of the minimum detection limit for FE-EPMA. As such, this enabled us to observe the distribution of minor dopants in EDF. Moreover, we propose a very simple sample preparation to prevent electron-beam radiation damage, a problem involved with FE-EPMA of low-conductivity materials such as SiO2 glass, which is the main component of EDF.
ANTISLAVERY IMPULSES
Authors: ABZUG ROBERT H. 
Published: November 2015

The year 2015 marks not only the sesquicentennial of Appomattox but also the fiftieth anniversary of the publication of Martin Duberman's anthology The Antislavery Vanguard, a collection of essays that set the agenda for an ever-expanding treatment of antislavery that continues to this day. In assessing these new additions to that literature, I began to think about the arc that historians of American abolitionism have traced in the past half-century, and the ways in which Kytle and McDaniel were inheritors and extenders of that historiographical revolution. Duberman defined his purpose as bringing together the work of historians bent on overthrowing a long-prevailing view of abolitionists as “meddlesome fanatics . . . wrapped in their self-righteous fury, who did so much to bring on a needless war.” He initially imagined a volume that would debate abolitionist virtue and vice but could find no scholars who would uphold the older stereotype. Instead, his contributors explored themes largely sympathetic to the reformers.
THE DEVIL IN DISGUISE
Authors: Castro Robert F. , Gao Rihao 
Published: November 2015

AbstractFor generations, Mexican and American Indian populations reciprocally and ritualistically took captives from one another’s societies in what are today the U.S.-Mexico borderlands. These captive-taking wars breached the expansion of the American state into the west (1850s) and tested the ability of the American state to enforce law and policy in a frontier environment. This intriguing history, however, has yet to be addressed in legal and social science research on race. Our goal in this article is two-fold: (1) to determine whether the captive status of individuals taken in these endemic borderland wars is visible within surviving U.S. administrative materials (e.g., census); and (2) to determine whether close analysis of census materials can be used to ascertain whether federal liberators were able to abolish the captive-taking trade relative to their official mandate. The authors analyze a core sample of 1860s-era census materials from the City of Santa Fe, New Mexico—which has a documented history of Indian captivity and enslavement—as well as church records to determine whether these materials indicate the continuance of captivity even after federal liberators had the opportunity to abolish the trade.
MERGING OF OPINIONS AND PROBABILITY KINEMATICS
Authors: HUTTEGGER SIMON M. 
Published: November 2015

AbstractWe explore the question of whether sustained rational disagreement is possible from a broadly Bayesian perspective. The setting is one where agents update on the same information, with special consideration being given to the case of uncertain information. The classical merging of opinions theorem of Blackwell and Dubins shows when updated beliefs come and stay closer for Bayesian conditioning. We extend this result to a type of Jeffrey conditioning where agents update on evidence that is uncertain but solid (hard Jeffrey shifts). However, merging of beliefs does not generally hold for Jeffrey conditioning on evidence that is fluid (soft Jeffrey shifts, Field shifts). Several theorems on the asymptotic behavior of subjective probabilities are proven. Taken together they show that while a consensus nearly always emerges in important special cases, sustained rational disagreement can be expected in many other situations.
Faith and impartiality in humanitarian response: Lessons from Lebanese evangelical churches providing food aid
Authors: Kraft Kathryn 
Published: November 2015

AbstractThis case study of a network of evangelical churches in Lebanon, based on data collected during an evaluation in 2014, presents a critique of common understandings about the humanitarian principle of impartiality, and questions assumptions about the compatibility between religious fervour and humanitarian values. Churches attempting to respect impartiality while implementing a food aid project for Syrian refugees have sought to mitigate potential problems through relationship-building and promotion of human dignity in order to ensure needs-responsiveness. Though many Lebanese Evangelical Christians do continue to engage in evangelistic activity, they benefit from strong community ties and demonstrate a high level of sensitivity to their beneficiaries' urgent needs as well as their sense of dignity.

Published: November 2015

AbstractGraphene flakes with giant shape anisotropy are extensively used to establish connectedness electrical percolation in various heterogeneous systems. However, the percolation behaviour of graphene flakes has been recently predicted to be far more complicated than generally anticipated on the basis of excluded volume arguments. Here we confirm experimentally that graphene flakes self-assemble into nematic liquid crystals below the onset of percolation. The competition of percolation and liquid crystal transition provides a new route towards high-k materials. Indeed, near-percolated liquid-crystalline graphene-based composites display unprecedented dielectric properties with a dielectric constant improved by 260-fold increase as compared with the polymer matrix, while maintaining the loss tangent as low as 0.4. This performance is shown to depend on the structure of monodomains of graphene liquid-crystalline phases. Insights into how the liquid crystal phase transition interferes with percolation transition and thus alters the dielectric constant are discussed.
Identification and characterization of multiple rubisco activases in chemoautotrophic bacteria

Published: November 2015

AbstractRibulose-1,5-bisphosphate carboxylase/oxygenase (rubisco) is responsible for almost all biological CO2 assimilation, but forms inhibited complexes with its substrate ribulose-1,5-bisphosphate (RuBP) and other sugar phosphates. The distantly related AAA+ proteins rubisco activase and CbbX remodel inhibited rubisco complexes to effect inhibitor release in plants and α-proteobacteria, respectively. Here we characterize a third class of rubisco activase in the chemolithoautotroph Acidithiobacillus ferrooxidans. Two sets of isoforms of CbbQ and CbbO form hetero-oligomers that function as specific activases for two structurally diverse rubisco forms. Mutational analysis supports a model wherein the AAA+ protein CbbQ functions as motor and CbbO is a substrate adaptor that binds rubisco via a von Willebrand factor A domain. Understanding the mechanisms employed by nature to overcome rubisco’s shortcomings will increase our toolbox for engineering photosynthetic carbon dioxide fixation.

AbstractCetacean mass strandings occur regularly worldwide, yet the compounded effects of natural and anthropogenic factors often complicate our understanding of these phenomena. Evidence of past stranding episodes may, thus, be essential to establish the potential influence of climate change. Investigations on bones from the site of Grotta dell’Uzzo in North West Sicily (Italy) show that the rapid climate change around 8,200 years ago coincided with increased strandings in the Mediterranean Sea. Stable isotope analyses on collagen from a large sample of remains recovered at this cave indicate that Mesolithic hunter-gatherers relied little on marine resources. A human and a red fox dating to the 8.2-kyr-BP climatic event, however, acquired at least one third of their protein from cetaceans. Numerous carcasses should have been available annually, for at least a decade, to obtain these proportions of meat. Our findings imply that climate-driven environmental changes, caused by global warming, may represent a serious threat to cetaceans in the near future.

AbstractNitrogen oxides are textbook class of molecular compounds, with extensive industrial applications. Nitrogen and oxygen are also among the most abundant elements in the universe. We explore the N-O system at 0 K and up to 500 GPa though ab initio evolutionary simulations. Results show that two phase transformations of stable molecular NO2 occur at 7 and 64 GPa and followed by decomposition of NO2 at 91 GPa. All of the NO+NO3− structures are found to be metastable at T = 0 K, so experimentally reported ionic NO+NO3− is either metastable or stabilized by temperature. N2O5 becomes stable at 9 GPa and transforms from P-1 to C2/c structure at 51 GPa. NO becomes thermodynamically stable at 198 GPa. This polymeric phase is superconducting (Tc = 2.0 K) and contains a -N-N- backbone.

Published: November 2015

AbstractConcerted efforts in genomic studies examining RNA transcription and DNA methylation patterns have revealed profound insights in prognostic ovarian cancer subtypes. On the other hand, abundant histology slides have been generated to date, yet their uses remain very limited and largely qualitative. Our goal is to develop automated histology analysis as an alternative subtyping technology for ovarian cancer that is cost-efficient and does not rely on DNA quality. We developed an automated system for scoring primary tumour sections of 91 late-stage ovarian cancer to identify single cells. We demonstrated high accuracy of our system based on expert pathologists’ scores (cancer = 97.1%, stromal = 89.1%) as well as compared to immunohistochemistry scoring (correlation = 0.87). The percentage of stromal cells in all cells is significantly associated with poor overall survival after controlling for clinical parameters including debulking status and age (multivariate analysis p = 0.0021, HR = 2.54, CI = 1.40–4.60) and progression-free survival (multivariate analysis p = 0.022, HR = 1.75, CI = 1.09–2.82). We demonstrate how automated image analysis enables objective quantification of microenvironmental composition of ovarian tumours. Our analysis reveals a strong effect of the tumour microenvironment on ovarian cancer progression and highlights the potential of therapeutic interventions that target the stromal compartment or cancer-stroma signalling in the stroma-high, late-stage ovarian cancer subset.

AbstractThree genome-wide association studies (GWAS) have been conducted on the genetic susceptibility of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC), two of which consistently identified tagging single nucleotide polymorphisms (SNPs) around HLA-DQ/DR. In contrast, large multi-centre association studies between HBV genotype, mutations and the risk of HCC are relatively rare and their interactions with host variants are even less. We performed a multi-centre study of 1,507 HBV-related HCC cases and 1,560 HBV persistent carriers as controls to evaluate the effects of HBV genotype, mutations, GWAS-identified HLA-DQ/DR SNPs (rs9272105 and rs9275319) and their interactions on HCC risk. We found HBV genotype C was more frequent in HBV-related HCC. And 11 HBV hotspot mutations were independently and significantly associated with HCC risk. We also detected significant interactions of rs9272105 with both the HBV genotype and mutations. Through stepwise regression analysis, HBV genotype, the 11 mutations, HLA-DQ/DR SNPs and the interaction of rs9272105 with mutation A1752G were all entered into the HCC prediction model and the area under the curve for the panel including the HLA-DQ/DR SNPs, HBV genotype and mutations was 0.840. The HBV genotype, the mutations and the HLA-DQ/DR SNPs may serve as biomarkers for the surveillance of HBV persistent carriers.
