Iron reduction and sulfate reduction often occur simultaneously in anoxic systems, and where that is the case, the molar ratio between the reactions (i.e., Fe/SO42− reduced) influences their impact on water quality and carbon storage. Previous research has shown that pH and the supply of electron donors and acceptors affect that ratio, but it is unclear how their influences compare and affect one another. This study examines impacts of pH and the supply of acetate, sulfate, and goethite on the ratio of iron to sulfate reduction in semi‐continuous sediment bioreactors. We examined which parameter had the greatest impact on that ratio and whether the parameter influences depended on the state of each other. Results show that pH had a greater influence than acetate supply on the ratio of iron to sulfate reduction, and that the impact of acetate supply on the ratio depended on pH. In acidic reactors (pH 6.0 media), the ratio of iron to sulfate reduction decreased from 3:1 to 2:1 as acetate supply increased (0–1 mM). In alkaline reactors (pH 7.5 media), iron and sulfate were reduced in equal proportions, regardless of acetate supply. Secondly, a comparison of experiments with and without sulfate shows that the extent of iron reduction was greater if sulfate reduction was occurring and that the effect was larger in alkaline reactors than acidic reactors. Thus, the influence of sulfate supply on iron reduction extent also depended on pH and suggests that iron reduction grows more dependent on sulfate reduction as pH increases. Our results compare well to trends in groundwater geochemistry and provide further evidence that pH is a major control on iron and sulfate reduction in systems with crystalline (oxyhydr)oxides. pH not only affects the ratio between the reactions but also the influences of other parameters on that ratio.

Methanogenesis and iron reduction play major roles in determining global fluxes of greenhouse gases. Despite their importance, environmental factors that influence their interactions are poorly known. Here, we present evidence that pH significantly influences the balance between each reaction in anoxic environments that contain ferric (oxyhydr)oxide minerals. In sediment bioreactors that contained goethite as a source of ferric iron, both iron reduction and methanogenesis occurred but the balance between them varied significantly with pH. Compared to bioreactors receiving acidic media (pH 6), electron donor oxidation was 85% lower for iron reduction and 61% higher for methanogenesis in bioreactors receiving alkaline media (pH 7.5). Thus, methanogenesis displaced iron reduction considerably at alkaline pH. Geochemistry data collected from U.S. aquifers demonstrate that a similar pattern also exists on a broad spatial scale in natural settings. In contrast, in bioreactors that were not augmented with goethite, clay minerals served as the source of ferric iron and the balance between each reaction did not vary significantly with pH. We therefore conclude that pH can regulate the relative contributions of microbial iron reduction and methanogenesis to carbon fluxes from terrestrial environments. We further propose that the availability of ferric (oxyhydr)oxide minerals influences the extent to which the balance between each reaction is sensitive to pH. The results of this study advance our understanding of environmental controls on microbial methane generation and provide a basis for using pH and the occurrence of ferric minerals to refine predictions of greenhouse gas fluxes.

Millions of households globally rely on uncultivated ecosystems for their livelihoods. However, much of the understanding about the broader contribution of uncultivated ecosystems to human wellbeing is still based on a series of small-scale studies due to limited availability of large-scale datasets. We pooled together 11 comparable datasets comprising 232 settlements and 10,971 households in ten low-and middle-income countries, representing forest, savanna and coastal ecosystems to analyse how uncultivated nature contributes to multi-dimensional wellbeing and how benefits from nature are distributed between households. The resulting dataset integrates secondary data on rural livelihoods, multidimensional human wellbeing, household demographics, resource tenure and social-ecological context, primarily drawing on nine existing household surveys and their associated contextual information together with selected variables, such as travel time to cities, population density, local area GDP and land use and land cover from existing global datasets. This integrated dataset has been archived with ReShare (UK Data Service) and will be useful for further analyses on nature-wellbeing relationships on its own or in combination with similar datasets.

The levitation tricompartment offloader (TCO) brace is designed to unload all three knee compartments by reducing compressive forces caused by muscle contraction. This study aimed to determine the effect of the TCO on knee contact forces and quadriceps muscle activity in individuals with knee osteoarthritis. Lower limb kinematics, kinetics, and electromyography data were collected during a chair rise‐and‐lower task. A three‐dimensional inverse dynamics model of the lower leg and foot was used with a sagittal plane knee model to compute knee joint forces. TCO brace use significantly decreased forces in the tibiofemoral [p = 0.001; mean difference, MD (97.5% confidence interval, CI) −0.62 (−0.91, −0.33) body weight (BW)] and patellofemoral [p = 0.001; MD (97.5% CI) −0.88 (−1.36, −0.39) BW] compartments in high‐power mode. Significant reductions in quadriceps tendon force [p = 0.002; MD (97.5% CI) −0.53 (−0.83, −0.23) BW] and electromyography intensity of the vastus medialis [p = 0.018, MD (97.5% CI) −30.7 (−59.1, −2.3)] and vastus lateralis [p = 0.012, MD (97.5% CI) −26.2 (−48.5, −3.9)] were also observed. The TCO significantly reduced tibiofemoral and patellofemoral contact forces throughout chair lower, and when knee flexion was greater than 50° during chair rise in high power. These results demonstrate that the TCO reduces contact forces in the tibiofemoral and patellofemoral joint compartments and confirms that the TCO unloads the joint by reducing compressive forces caused by the quadriceps. Clinical significance: The magnitude of knee joint unloading provided by the TCO is similar to that achieved by clinically recommended levels of bodyweight loss and is therefore expected to result in clinical benefits for knee osteoarthritis patients.

In her paper, Janet Landa argues that the key behind the success of the ethnically homogeneous Chinese middleman group (EHMG) is their highly developed in-group cooperation. She places the EHMG phenomenon within the framework of evolutionary biology by calling it 'a cultural transmission unit' subject to the influence of both genes and culture. Landa suggests that the individual members of the EHMG comprise the units of selection for EHMG groups much like the genes comprise the units of selection for individual organisms. However, evolution occurs through the differential survival and reproduction of individual organisms. In order to meet the criteria of biological group selection, it would have to be demonstrated that groups in competition with EHMGs had gone extinct. The fact that the EHMGs are simply faring better than their competitors is not evidence for group selection. The other reason biological group selection is not really applicable to EHMGs is that there are no physical/biological barriers to exogamous mating, and cultural barriers are intrinsically unstable.

This paper showcases how a reflexive practice, that includes arts-based activities, deepened understandings experienced by a doctoral student of psychology while completing the data analysis section of a metasynthesis. The metasynthesis focused on qualitative studies, examining the mental and spiritual care of persons living with diabetic foot ulcers. Reflecting on the experience, this work argues for spaces where researchers stop and engage in reflexivity, making the work more robust. [ABSTRACT FROM AUTHOR]

Abstract: Based on the analysis of its genome sequence, the ectomycorrhizal (ECM) basidiomycetous fungus Laccaria bicolor was shown to be lacking many of the major classes of secreted enzymes that depolymerize plant cell wall polysaccharides. To test whether this is also a feature of other ECM fungi, we searched a survey genome database of Amanita bisporigera with the proteins found in the secretome of Trichoderma reesei (syn. Hypocrea jecorina), a biochemically well-characterized industrial fungus. Additional proteins were also used as queries to compensate for major groups of cell-wall-degrading enzymes lacking in the secretome of T. reesei and to substantiate conclusions drawn from the T. reesei collection. By MS/MS-based “shotgun” proteomics, 80 proteins were identified in culture filtrates of T. reesei strain RUTC30 grown on corn cell walls and in a commercial “cellulase” preparation, Spezyme CP. The two T. reesei enzyme preparations were qualitatively and quantitatively similar, the most striking difference being the lack of at least five major peptidases from the commercial enzyme mixture. Based on our analysis of A. bisporigera, this ECM fungus is deficient in many major classes of cell-wall-degrading enzymes, including both glycosyl hydrolases and carbohydrate esterases. By comparison, the genomes of the saprophytic basidiomycetes Coprinopsis cinerea and Galerina marginata (using a genome survey sequence approximately equivalent in depth to that of A. bisporigera) have, like T. reesei, a much more complete complement of cell-wall-degrading enzymes.

During the course of his project on the charters of William Rufus and Henry I, Richard Sharpe will have worked on British Library Additional Manuscript 38816 and recognised the importance of its contents for the history of St Mary's. Abbot Stephen's is a first-person narrative, which puts himself at the centre of events, but it is not an autobiography; it is intended as a record of founders and patrons and the management of St Mary's assets. Earlier accounts of the origins of St Mary's have not stressed royal policy, largely because they have followed Abbot Stephen's narrative. [Extracted from the article]

This paper suggests and tests a psychological model of environmental art perception and subsequent support for climate change policies. The model is based on findings from art perception and environmental psychology, which indicate that the response of the viewer to the artwork is (1) first an emotional reaction, which can be positive and/or negative. The emotional activation leads to (2) evaluation of the perceived quality of the artwork. This forms the first impression of the artwork the viewer gets, which then triggers (3) reflections on the artwork that are finally related to support for climate policies. The model test uses data collected at the ArtCOP21 that accompanied the 21st UN climate summit in Paris. At 37 connected events, the research team collected 883 audience responses with a brief quantitative paper-pencil questionnaire. The data were analyzed using a multilevel-structural equation modeling approach. Results support the suggested theoretical model. Moreover, the effect of reflections on the artwork on support for climate policies is moderated by environmental attitudes, meaning the lower the environmental attitudes, the higher the effect of reflections on policy support. Finally, artwork features like color, size, displaying something personal, etc., could be identified that had a significant relation to differences on the artwork level regarding the first impression of the artwork and the reflections elicited. The study shows that being confronted with climate change-related artwork relates at least in the short run to increased climate policy support, which is mostly channeled through an emotional activation with following cognitive processing. Features of the artwork relate to how strongly and which emotions are activated. [ABSTRACT FROM AUTHOR]

The renunciation of the devil in the rite of baptism appears in high frequency in baptismal expositions, royal capitularies, acts of church councils, and popular sermons during the later reign of Charlemagne. Close examination of these sources demonstrates a discourse of reform that centers on the proper life and conduct of Christians. In reply to Charlemagne's questions in his encyclical letter on baptism, authors of baptismal expositions commonly expounded baptismal renunciation as a symbol of Christians' moral conversion. Charlemagne projected his deep solicitude for the life and conduct of ecclesiastics of his realm on the issue of the renunciation of the devil in two capitularies of 811. Archbishop Leidrad of Lyon elaborated his exposition on baptismal renunciation in his second letter of reply to Charlemagne on baptism, which preserves a sample of how an ecclesiastical leader responded to the emperor's reform concerns. Several popular sermons from the later reign of Charlemagne reveal how the moralistic discourse of the renunciation of the devil was disseminated to common Christians. Baptismal renunciation was part of the rhetoric of Charlemagne's empire, and various modes of communication that involved the agency of multiple parties made it a totalizing discourse of reform.

Since the early twentieth century dissociative disorder has undergone a decline and since the seventies the field of psychiatry has begun its path of medicalization. Dissociative disorders are complex disorders that activate within the therapeutic setting specific dynamics related to traumatic family relationships. Recognizing and dealing with it becomes necessary before defining any pharmacological treatment. This paper aims to review some crucial issues on the history of dissociative disorders and medical model of mental disorders. The article wants also to highlight the importance of the therapeutic alliance specifically in the first contacts with dissociative patients, the main role of the psychotherapist in treating Dissociative Identity Disorders (DID) and it wants to suggest some strategies to cope with these patients in the integrated settings of therapy.

Cyanogen iodide (ICN) has been photodissociated at 249 nm. The CN(X 2Σ+) photofragments were probed by laser induced fluorescence (LIF) using multiple distinct excitation–detection geometries, allowing the extraction of bipolar moments describing the distribution and mutual correlations of the fragment velocity, angular momentum, and dipole moment vectors. The results of this analysis are consistent with three optically active transitions at this photolysis wavelength, one with parallel character and two with perpendicular character. One of these perpendicular transitions has the direction of the transition dipole moment perpendicular to the plane of the three atoms, whereas the other has the transition moment in the plane of the three atoms, perpendicular to the I–C bond. This picture can be reconciled with recent ab initio calculations of the level structure of the ICN A–X continuum and can also be used as a framework to explain in a consistent manner many of the gross features of the photodissociation dynamics of ICN observed in previous experiments at this wavelength.

This paper suggests some far-reaching symbolic implications for women's hair in Latin love elegy. Hairdressing, hairdressers and hair loss provided a metaphorical vehicle by which Tibullus (1.8), Propertius (2.18) and above all Ovid ( Ars Amatoria 3; Amores 1.11-12, 2.7-8, 1.7, and 1.14) interrogate the power relationships that underpin Roman society: between master and slave, women and men, Rome and her provinces. In my analysis, elegiac hair becomes an index to the socioeconomic realities of urban selffashioning as well as a locus of anxiety about Rome's increasing reliance on imported labor and consumer goods.

As the circular economy (CE) gains traction in literature and practice, several academic communities are opening up spaces that move away from the CE as a pure engineering concept. This systematic literature review (n = 77) analyses and discusses the fragmented body of knowledge on the meso-level of supply chains (SCs): (a) to find common ground that underpins the current implementation of the CE on this level; and (b) to identify drivers, inhibitors, and enablers from which CE SC configurations emerge. The review finds that there remain differences in CE definitions that result from claimed antecedents and scopes, resulting in distinct research streams. On the meso-level, eco-industrial parks, environmental SCs, and closed-loop SCs each face significant challenges. The latter potentially offers the largest environmental benefits but engenders radical changes for business models and exposes SCs to more risk. We firstly argue for moving away from using a prescriptive set of practices as definitions for the CE towards a set of overarching goals to allow for the inclusion of future practices and techniques. Secondly, we highlight that research going beyond the meso-level to consider the wider social and institutional environment is needed to solve current challenges. [ABSTRACT FROM AUTHOR]

'The Pearl of Great Price' is a short story that explores the ways faith can go wrong. The central character, Janet, a single mom in a dead end job, is drawn into a multi-level marketing scheme, Benevite, by an unscrupulous salesman. She is encouraged to believe in herself and her dream and to give everything she has to it. She is fed the standard clichés to the effect that you can achieve whatever you want if you try hard enough. In the end her faith in her dream leads to the loss of her relationship with her child and other losses. Her pursuit exhibits many of the standard features of faith, belief, desire, resilience, tenacity, passion, and yet she does not save herself. The story is not meant as an indictment of faith in general, but as an acknowledgement of the fact that faith can be a vice and an exploration of when this might be so. [ABSTRACT FROM AUTHOR]

In 1948, Angus Bateman published a paper on fruit flies that tested Charles Darwin’s ideas of sexual selection. Based on this one fruit fly study, Bateman concluded that because males are able to produce millions of small sperm, males are likely to behave promiscuously, mating with as many females as possible. On the other hand, because females produce relatively fewer, larger, and presumably more expensive eggs, females are likely to be very discriminating in selecting only one high-quality sexual partner. He also posited that a male’s reproductive success increases linearly with the number of females he is able to mate with, but that a female’s reproductive success peaks after she mates with only one male. Consequently, in almost all organisms, sexual selection acts most strongly on males. These ideas became a recurring theme in attempts to explain wide-ranging differences in male and female behavior not only in nonhuman animals but also in humans. As such, Bateman’s conclusions and predictions have become axiomatic and, at times, have gone unquestioned even when modern empirical data do not conform to this model. This article reviews the origins and history of these ideas and uses modern data to highlight the current and growing controversy surrounding the validity and general applicability of this paradigm.

Psillos (, ), Kitcher (), and Leplin () have defended convergent scientific realism against the pessimistic meta-induction by arguing for the divide et impera (DEI) strategy. I argue that DEI faces a problem more serious than the pessimistic meta-induction: the problem of accretion. When empirically successful theories and principles are combined, they may no longer make successful predictions or allow for accurate calculations, or the combination otherwise may be an empirical failure. The shift from classical mechanics to the new quantum theory does not reflect the discarding of 'idle wheels.' Instead, scientists had to contend with new principles that made classical calculations difficult or impossible (the Maxwell-Boltzmann equipartition theorem), and new results (the anomalous Zeeman effect) that were inconsistent with classical theorems (the Larmor theorem), and that suggested a new way of conceiving of atomic dynamics. In this shift, reference to atoms and to electrons was preserved, but the underlying causal explanations and descriptions of atoms and electrons changed. I propose that the emphasis on accurate description of causal agents as a virtue of background theory be replaced with Ruetsche's () advocacy of pragmatic, modal resourcefulness.

The main goal of this article is to provide an answer to the question: does anything forecast exchange rates, and if so, which variables? It is well known that exchange rate fluctuations are very difficult to predict using economic models, and that a random walk forecasts exchange rates better than any economic model (the Meese and Rogoff puzzle). However, the recent literature has identified a series of fundamentals/ methodologies that claim to have resolved the puzzle. This article provides a critical review of the recent literature on exchange rate forecasting and illustrates the new methodologies and fundamentals that have been recently proposed in an up-to-date, thorough empirical analysis. Overall, our analysis of the literature and the data suggests that the answer to the question: 'Are exchange rates predictable?' is, 'It depends'-on the choice of predictor, forecast horizon, sample period, model, and forecast evaluation method. Predictability is most apparent when one or more of the following hold: the predictors are Taylor rule or net foreign assets, the model is linear, and a small number of parameters are estimated. The toughest benchmark is the random walk without drift. (JEL C53, F31, F37, E43, E52) [ABSTRACT FROM AUTHOR]

It is impossible to consider the impact of anti-discrimination law on persons with mental disabilities without a full understanding of how sanism permeates all aspects of the legal system – judicial opinions, legislation, the role of lawyers, juror decision-making – and the entire fabric of society. For those unfamiliar with the term, I define “sanism” as an irrational prejudice of the same quality and character as other irrational prejudices that cause and are reflected in prevailing social attitudes of racism, sexism, homophobia, and ethnic bigotry,1that permeates all aspects of mental disability law and affects all participants in the mental disability law system: litigants, fact finders, counsel, and expert and lay witnesses.2  Notwithstanding over two decades of anti-discrimination laws3and, in many jurisdictions, an impressive corpus of constitutional case law and state statutes,4the attitudes of judges, jurors and lawyers often reflect the same level of bigotry that defined this area of law half a century ago.5The reasons for this are complex and, to a great extent, flow from centuries of prejudice – often hidden prejudice, often socially acceptable prejudice6– that has persisted in spite of prophylactic legislative and judicial reforms, and – at least superficially – an apparent uptick in public awareness. I have railed multiple times about the “irrational,” “corrosive”, “malignant” and “ravaging” effects of sanism, but its “pernicious power” still poisons all of mental disability law.7  The recently-ratified Convention on the Rights of Persons with Disabilities (CRPD) is the most revolutionary international human rights document – ever – that applies to persons with disabilities. The Disability Convention furthers the human rights approach to disability and recognizes the right of people with disabilities to equality in most every aspect of life. It firmly endorses a social model of disability – a clear and direct repudiation of the medical model that traditionally was part-and-parcel of mental disability law. It calls for “respect for inherent dignity” and “non-discrimination.” Subsequent articles declare “freedom from torture or cruel, inhuman or degrading treatment or punishment,” “freedom from exploitation, violence and abuse,” and a right to protection of the “integrity of the person.”  In this paper, I consider the impact that the Convention is likely to have on sanism. First, I will briefly discuss both our sanist past and our sanist present. Then, I will consider how the CRPD has the greatest potential for combating sanism, and for changing social attitudes. In this latter inquiry, I will also draw on the tools of therapeutic jurisprudence. Then, I will offer some brief and modest conclusions. [ABSTRACT FROM PUBLISHER]

ABSTRACT A number of authors have objected to potential parents' use of reproductive genetic technologies on the grounds that the use of these technologies reflects a morally problematic attitude toward parenting. More specifically, proponents of this view have argued that such a choice is inconsistent with the unconditional acceptance that lies at the heart of praiseworthy parental attitudes. This paper offers a rebuttal of this view by arguing that it is possible for a parent to exhibit unconditional acceptance of the child herself without accepting each of that child's traits. If this is true, the use of reproductive genetic technologies does not inherently undermine appropriate parental attitudes. Further, by working to change some of a child's specific traits, a parent may instead exemplify an aspirational aspect of praiseworthy parenting and so demonstrate appropriate parental attitudes.

This paper describes the early history of magnetochemistry: the search for chemical effects of magnetism in the nineteenth century. Some early researchers, such as Johann Wilhelm Ritter, attempted to reproduce with magnets the effects that had been produced by electricity and Volta's battery. For several decades, researchers successively reported positive results and denied claims concerning the effect of magnetism in oxidation, electrolysis, reduction of metals from saline solutions, crystallisation, change of colour of vegetable tinctures and other chemical reactions. In the two last decades of the nineteenth century some effects were accepted as real, and a thermodynamic theory of the influence of magnetic fields upon chemical reactions was developed. Finally, Dragomir Hurmuzescu was able to create reproducible experiments and measured the electromotive force between two electrodes, with or without the presence of magnetic fields, confirming the existence of the phenomenon and obtaining results compatible with the theoretical predictions. Afterwards, this magnetochemical effect was accepted as real, but the effect was weak and its practical importance was negligible. The subject was gradually forgotten. [ABSTRACT FROM AUTHOR]

Seasonal fluctuations in the occurrence of inshore South African Bryde's whales Balaenoptera edeni were investigated between November 2005 and June 2008. Sighting data were collected in Plettenberg Bay on the south-east coast of South Africa. Bryde's whale occurrence was modelled in relation to the following environmental covariates: sea surface temperature, chlorophyll a concentrations and wind speed. Seasonal increases in encounter rates (sightings per day) were observed during summer and autumn, with a peak in April that corresponded to increased feeding activity and above average aggregation sizes. All three environmental covariates were significant factors in terms of explaining variability in the occurrence of whales. Multispecies associations with common dolphins Delphinus capensis and Cape gannets Morus capensis were most common in summer and autumn, when feeding activity was highest. [ABSTRACT FROM PUBLISHER]

We explore the importance of meridional circulation variations in modelling the irregularities of the solar cycle by using the flux transport dynamo model. We show that a fluctuating meridional circulation can reproduce some features of the solar cycle like the Waldmeier effect and the grand minimum. However, we get all these results only if the value of the turbulent diffusivity in the convection zone is reasonably high. [ABSTRACT FROM PUBLISHER]

James Dunn responds gratefully to the commendatory critiques of Roger Stronstad, Janet Everts, Chris omas and Max Turner. Luke depicts the first coming of the Spirit into a life as both strikingly manifest and as life-giving; he does not envisage an earlier quiet coming. Paul understands the seal of the Spirit as the beginning of the process of salvation, individuals thus baptized in the Spirit and anointed into active ministry in the body. John likewise depicts the reception of the Spirit in John 7.39 and 20.22 as life-creating, the consequence of Christ's crucifixion-glorification. The area of agreement with Max Turner far exceeds the details of difference. [ABSTRACT FROM AUTHOR]

Janet is known almost exclusively for his left-step periodic table (LSPT). A study of his writings shows him to have been a highly creative thinker and a brilliant draftsman. His approach was primarily arithmetic-geometric, but it led him to anticipate the discovery of deuterium, helium-3, transuranian elements, antimatter and energy from nuclear fusion. He recognized the (n + l) rule well before Madelung and correctly placed the actinides. His controversial treatment of helium at the head of the alkaline earth elements might be less provocative if his system were taken in one of its spiral representations. [ABSTRACT FROM AUTHOR]

The author reflects on the study conducted by Janet Landa which presents evidence that cultural group strategies are a major factor in the development and continuity of ethnically homogenous middleman trading groups (HMGs). He expresses appreciation to Landa's autobiographical approach but asserts that her analysis does not explore biological factors. He suggests the incorporation of behavioral biological factors on the analysis, and discusses its importance to the success of HMGs.

Normatively and intuitively, we conceive of political participation as an integral component of democratic policymaking. However, research on participation generally does not include policy considerations as part of individuals’ decisions to engage in activism. I offer an opportunity model of participation that begins to study how policy goals shape individual participation and how aggregate participation shapes policymaking. The central argument is that individuals’ policy goals allow them to recognize those moments when it is most efficient and/or effective to take action. Examining black participation from 1980 to 1994, I show that black Americans are more likely to participate when they face external threats, are embedded in social networks, and have greater access to policymakers. Most importantly, the recognition of these opportunities varies according to individuals’ resources. This research moves beyond the discussion of who participates to address the equally fundamental question: participation for what? [ABSTRACT FROM AUTHOR]

Quality by design is an essential part of the modern approach to pharmaceutical quality. There is much confusion among pharmaceutical scientists in generic drug industry about the appropriate element and terminology of quality by design. This paper discusses quality by design for generic drugs and presents a summary of the key terminology. The elements of quality by design are examined and a consistent nomenclature for quality by design, critical quality attribute, critical process parameter, critical material attribute, and control strategy is proposed. Agreement on these key concepts will allow discussion of the application of these concepts to abbreviated new drug applications to progress. [ABSTRACT FROM AUTHOR]

In this paper we look at three identity positions salient in research of young people studying in complementary schools in Leicester, a large linguistically and ethnically diverse city in the East Midlands, England. Our discussion of identity focuses on three identity positions: multicultural, heritage and learner. The first two of these are linked to discussions on ethnicity as a social category. We explore the fluidity and stability of ethnicity as a social description in interview transcripts of young people at complementary schools. In addition, the paper explores another, more emergent identity salient in the two schools, that of `learner identity'. The research can be characterised as adopting a linguistic ethnographic approach using a team of ethnographers. Data was collected for 20 weeks by four researchers and consists of fieldnotes, interviews and audio recordings of classroom interactions. We consider the importance of ambiguity and certainty in students' conceptualisation of themselves around ethnicity and linguistic diversity and look at the institutional role complementary schools play in the production of these and successful learner identities. We explore how complementary schools privilege and encourage these particular identity positionings in their endorsement of flexible bilingualism. Overall, we argue that complementary schools allowed the children a safe haven for exploring ethnic and linguistic identities while producing opportunities for performing successful learner identity.

Study objective: There is evidence suggesting that artificial feeding is associated with a reduction in cognitive function in infants and children, in contrast with breast feeding, but the available evidence suffers from confounding by social and educational factors. An opportunity arose in the Caerphilly cohort study to examine relations between cognitive function in older men and their feeding as infants, when breast feeding was usual. Design: A prospective cohort study. Setting: Caerphilly, South Wales, UK, was a deprived coal mining community when the men had been born in 1920-35. Most had been breast fed as infants. Participants: 779 men aged 60-74 years when tested. The men had earlier been asked to obtain from their mothers their birth weight, and how they had been fed as infants. Results: Complete data were obtained for 779 men. In those whose birth weight had been at or above the median, the adjusted mean cognitive function was only slightly and non-significantly lower in those who had been artificially fed. In the men whose birth weight had been below the median, having been artificially fed was associated with significantly lower results in both a test of reasoning (the AI-14) and word power (the national adult reading test (NART)). Two standard deviations below the median birth weight, artificial feeding was associated with a reduction of six points (70% of a SD) on word power (the NART). Conclusions: In men whose birth weight had been low, having been artificially fed is associated with poorer cognitive function in late adult life. [ABSTRACT FROM AUTHOR]
