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.

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]

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.

The article offers information on conference "Mary Wollstonecraft; Life Work and Legacy" on International Women's Day. Topics include concerns provided towards public celebration and memorial and informed by Caroline Criado Perez to increase the public visibility of women in the Great Britain; and reports on leading campaigns to maintain the presence of a woman on bank notes issued by the Bank of England.

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.

Fucoidans are a class of sulfated fucose-rich polysaccharides found in brown marine algae and echinoderms. Fucoidans have an attractive array of bioactivities and potential applications including immune modulation, cancer inhibition, and pathogen inhibition. Research into fucoidan has continued to gain pace over the last few years and point towards potential therapeutic or adjunct roles. The source, extraction, characterization and detection of fucoidan is discussed. [ABSTRACT FROM AUTHOR]
