A rusty record of weathering and groundwater movement in the hyperarid Central Andes

The Atacama Desert, on the western margin of the Central Andes, hosts some of the world's largest porphyry copper deposits (PCDs). Despite a hyperarid climate, many of these PCDs have undergone secondary “supergene” enrichment, whereby copper has been concentrated via groundwater-driven leaching and reprecipitation, yielding supergene profiles containing valuable records of weathering and landscape evolution. We combine hematite (U-Th-Sm)/He geochronology and oxygen isotope analysis to compare the weathering histories of two Andean PCDs and test the relative importance of climate and tectonics in controlling both enrichment and water table movement. At Cerro Colorado, in the Precordillera, hematite precipitation records prolonged weathering from ∼31 to ∼2 Ma, tracking water table descent following aridity-induced canyon incision from the late Miocene onward. By contrast, hematite at Spence, within the Central Depression, is mostly younger than ∼10.5 Ma, suggesting exhumation ended much later. A heavy oxygen isotopic signature for Spence hematite suggests that upwelling formation water has been an important source of groundwater, accounting for a high modern water table despite persistent hyperaridity, whereas isotopically light hematite at Cerro Colorado formed in the presence of meteoric water. Compared with published paleo-environmental and sedimentological records, our data show that weathering can persist beneath appreciable post-exhumation cover, under hyperarid conditions unconducive to enrichment. The susceptibility of each deposit to aridity-induced water table descent, canyon incision and deep weathering has been controlled by recharge characteristics and morphotectonic setting. Erosional exhumation, rather than aridity-induced water table decay, appears to be more important for the development of supergene enrichment

The Validation of Macro and Micro Observations of Parent–Child Dynamics Using the Relationship Affect Coding System in Early Childhood

This study examined the validity of micro social observations and macro ratings of parent–child interaction in early to middle childhood. Seven hundred and thirty-one families representing multiple ethnic groups were recruited and screened as at risk in the context of Women, Infant, and Children (WIC) Nutritional Supplement service settings. Families were randomly assigned to the Family Checkup (FCU) intervention or the control condition at age 2 and videotaped in structured interactions in the home at ages 2, 3, 4, and 5. Parent–child interaction videotapes were microcoded using the Relationship Affect Coding System (RACS) that captures the duration of two mutual dyadic states: positive engagement and coercion. Macro ratings of parenting skills were collected after coding the videotapes to assess parent use of positive behavior support and limit setting skills (or lack thereof). Confirmatory factor analyses revealed that the measurement model of macro ratings of limit setting and positive behavior support was not supported by the data, and thus, were excluded from further analyses. However, there was moderate stability in the families’ micro social dynamics across early childhood and it showed significant improvements as a function of random assignment to the FCU. Moreover, parent–child dynamics were predictive of chronic behavior problems as rated by parents in middle childhood, but not emotional problems. We conclude with a discussion of the validity of the RACS and on methodological advantages of micro social coding over the statistical limitations of macro rating observations. Future directions are discussed for observation research in prevention science

Pathological and Phylogenetic characterisation of Amphibiothecum sp. infection in an isolated amphibian (Lissotriton helveticus) population on the island of Rum (Scotland)

Outbreaks of cutaneous infectious disease in amphibians are increasingly being attributed to an overlooked group of fungal-like pathogens, the Dermocystids. During the last 10 years on the Isle of Rum, Scotland, palmate newts (Lissotriton helveticus) have been reportedly afflicted by unusual skin lesions. Here we present pathological and molecular findings confirming that the pathogen associated with these lesions is a novel organism of the order Dermocystida, and represents the first formally reported, and potentially lethal, case of amphibian Dermocystid infection in the UK. Whilst the gross pathology and the parasite cyst morphology were synonymous to those described in a study from infectedL. helveticusin France, we observed a more extreme clinical outcome on Rum involving severe subcutaneous oedema. Phylogenetic topologies supported synonymy between Dermocystid sequences from Rum and France and as well as their distinction fromAmphibiocystidiumspp. Phylogenetic analysis also suggested that the amphibian-infecting Dermocystids are not monophyletic. We conclude that theL. helveticus-infecting pathogen represents a single, novel species;Amphibiothecum meredithae

Cold War Sport, Film and Propaganda : A Comparative Analysis of the Superpowers

This document is the author's original submitted manuscript (pre-print) version. An updated version has been published by MIT Press in Journal of Cold War Studies, available online at doi: https://doi.org/10.1162/JCWS_a_00721.Films and sports played central roles in Cold War popular culture. Each helped set ideological agendas domestically and internationally while serving as powerful substitutes for direct superpower conflict. This article brings film and sport together by offering the first comparative analysis of how U.S. and Soviet cinema used sport as an instrument of propaganda during the Cold War. The article explores the different propaganda styles that U.S. and Soviet sports films adopted and pinpoints the political functions they performed. It considers what Cold War sports cinema can tell us about political culture in the United States and the Soviet Union after 1945 and about the complex battle for hearts and minds that was so important to the East-West conflict.Peer reviewedFinal Published versio

Torture and the UK’s “war on asylum”: medical power and the culture of disbelief

When the now ‘iconic’ images of shackled, humiliated and dehumanised detainees in the Abu Ghraib prison complex in Iraq were broadcast globally, in the mid-2000s, the relationship between medical power and torture in the “war on terror” was also thrust sharply into focus. Graphic images of coalition troops photographing and posing in front of hooded, naked prisoners forced into a “human pyramid”, and of people made to wear animal collars, indicated a regime in which degradation had a defining role. The photograph of a soldier gloating over the corpse of a man who had died as a result of torture was just one picture of a network of interrogation camps in which detention by coalition forces could be fatal. Yet if there were any expectations that the presence of medical personnel may have checked this violence, these were shattered by the fact that clinicians – in some cases at least – were integral to its practice. «It is now beyond doubt that Armed Forces physicians, psychologists, and medics were active and passive partners in the systematic neglect and abuse of war on terror prisoners», wrote Steven Miles in 2009 (Miles 2009, X). And as he continued, this involved providing interrogators «with medical information to use in setting the nature and degree of physical and psychological abuse during interrogations». It involved monitoring «interrogations to devise ways to break prisoners down or to keep them alive». It involved pathologists holding back death certificates and autopsy reports in order to minimise the number of fatalities or cover up torture-related deaths as deaths by natural causes (Ibid). Procedures including «cramped confinement, dietary manipulation, sleep deprivation, and waterboarding» were among the practices that were «at times (…) legally sanctioned due to medical supervision» in the context of the “war on terror”, according to Hoffman (2011, 1535). He continued to suggest that doctors are not just important to «modern torture methods», they are «irreplaceable». In this context, the “war on terror” is no aberration. As the revolutionary psychoanalyst and philosopher Frantz Fanon documented in 1959, for example, certain medical practitioners had an integral role in the military occupation of Algeria, and «There are, for instance, psychiatrists … known to numerous prisoners», he suggested, «who have given electric shock treatments to the accused and have questioned them during the waking phase, which is characterized by a certain confusion, a relaxation of resistance, a disappearance of the person's defences.» (Fanon 1959/1965, 138). Indeed, in his analysis of the Algerian revolution, he discussed how resistance to and struggles over the meanings of medical power were integral to the revolution itself. However, while the role of medical power in the practice of torture has been subjected to sustained critique in the context of the “war on terror”, what follows examines the relationship between medical power and torture in the context of what has been depicted – metaphorically – as another (although to some extents related) “war”: the “war” on asylum. According to the UNHCR (2017, 3), between 5 and 35 per cent of those asylum seekers who have been granted refugee status have survived torture. And focusing on the UK as a case study, this chapter examines the institutional and legal structures prohibiting torture and inhuman and degrading treatment, particularly as they apply to those subject to immigration control in this context. But further, it also examines the ideological and political conditions within which claims by those seeking asylum that they have been subjected to torture prior to arrival can be (and have been) ignored, downplayed and denied. It examines how medical expertise has frequently been undermined in the asylum process when this expertise is utilised to add weight to asylum seekers’ claims to have experienced torture. It examines how there have been attempts to narrow the definition of torture in ways which exclude people from the protections to which torture survivors are entitled. But it also explores the ways in which segments of the medical profession have been complicit in riding roughshod over existing safeguards to prevent further harm to those who have experienced torture, thus potentially compounding its effects. In particular, it examines claims that in certain contexts clinicians have administered dangerous “care” in order to ensure the removal of people from the UK, despite them claiming that they – or their family members – face serious harm and persecution on arrival as a result of this. In a historical discussion of medical involvement in torture, Giovanni Maio (2001, 1609) has noted that from its earliest incarnations one of the features of torture has been its use as an «oppressive instrument used in the preservation of power». Furthermore, whilst methods of torture have certainly «developed», and continue to do so, he argues, this «function» of torture is «especially relevant today». This chapter argues that the (mis)treatment of those in the UK who say they have been tortured, preserves and is bound up with a particular manifestation of state power: the aims, rationale and dictates of immigration control. Its claims are perhaps much more mundane than the forms of direct medical complicity in torture alluded to above. But they are nonetheless important. For it is argued that the acts of omission and commission documented in this chapter expose the tensions between the rights of certain “categories” of migrants to be afforded adequate clinical care on the one hand, and the goals and aims of immigration control itself on the other. This poses profound questions about the functions of clinical care and the ethical duties, responsibilities and obligations of clinicians, it is suggested. But as this chapter also crucially explores, this is a form of power that many within the medical profession have historically challenged, and continue to do so

"They go for gender first"

There have been many recent media reports about the online harassment of women journalists working in technology, particularly the video gaming industry. However, little research has focused on this aspect, by looking at specific occupations, or analysing the implications for women and society. This paper is a feminist study of the experiences of sexist abuse of a sample of women journalists writing about technology. It is a commentary on the results of a questionnaire-based study of 102 women (and their approximately 300 comments) that work in what has emerged as one of the frontlines of the struggle for gender equality. The research looks at the extent of the abuse, the harm it causes and how women are reacting to it. Most of the participants have experienced abuse, many have changed their working practices and some have disguised their identity to avoid it. An examination of their comments suggests that sexist abuse is now often normalised, alongside a new kind of "invisible" feminism. It also reveals a mood of defiance and an appetite for radical change to address the problems of exclusion and loss of identity. Overall, results indicate that the abuse is damaging women’s lives and impacting journalism and society in a negative way

Domestication of Campylobacter jejuni NCTC 11168

Reference and type strains of well-known bacteria have been a cornerstone of microbiology research for decades. The sharing of well-characterized isolates among laboratories has run in parallel with research efforts and enhanced the reproducibility of experiments, leading to a wealth of knowledge about trait variation in different species and the underlying genetics. Campylobacter jejuni strain NCTC 11168, deposited at the National Collection of Type Cultures in 1977, has been adopted widely as a reference strain by researchers worldwide and was the first Campylobacter for which the complete genome was published (in 2000). In this study, we collected 23 C . jejuni NCTC 11168 reference isolates from laboratories across the UK and compared variation in simple laboratory phenotypes with genetic variation in sequenced genomes. Putatively identical isolates, identified previously to have aberrant phenotypes, varied by up to 281 SNPs (in 15 genes) compared to the most recent reference strain. Isolates also display considerable phenotype variation in motility, morphology, growth at 37 °C, invasion of chicken and human cell lines, and susceptibility to ampicillin. This study provides evidence of ongoing evolutionary change among C. jejuni isolates as they are cultured in different laboratories and highlights the need for careful consideration of genetic variation within laboratory reference strains.

Teaching psychology to student nurses: the use of talking heads videos

Psychology is a central part of undergraduate nursing curricula in the UK.However, student nurses report difficulties recognising the relevance and value of psychology. We sought to strengthen first-year student nurses’ application of psychology by developing a set of digital stories based around ‘Talking Head’video clips where authentic patients relate their experiences of illness and nursing care. The aim of this article is to discuss the technological, organisational and pedagogical challenges, student and staff evaluations and our recommendations for the future of Talking Heads. First-year student nurses were shown a video clip of a patient talking about their illness experiences followed by a group learning situation linking main themes to psychology and nursing. Students and staff valued the authenticity of patient’s narrative, found the video clip easy to follow,reported a raised awareness of psychological concepts and improved empathetic understanding of chronic illness. Negative evaluations were related to a sanitised, untypical representation and limited internet access. This small-scale study highlighted how patient narrative may enhance students understanding of illness experience. It chronicles the development and evaluation of a Talking Head in a specific context but which may be useful across disciplines
