- Abstract
Data analysis workflows in many scientific domains have become increasingly complex and flexible. Here we assess the effect of this flexibility on the results of functional magnetic resonance imaging by asking 70 independent teams to analyse the same dataset, testing the same 9 ex-ante hypotheses1. The flexibility of analytical approaches is exemplified by the fact that no two teams chose identical workflows to analyse the data. This flexibility resulted in sizeable variation in the results of hypothesis tests, even for teams whose statistical maps were highly correlated at intermediate stages of the analysis pipeline. Variation in reported results was related to several aspects of analysis methodology. Notably, a meta-analytical approach that aggregated information across teams yielded a significant consensus in activated regions. Furthermore, prediction markets of researchers in the field revealed an overestimation of the likelihood of significant findings, even by researchers with direct knowledge of the dataset2–5. Our findings show that analytical flexibility can have substantial effects on scientific conclusions, and identify factors that may be related to variability in the analysis of functional magnetic resonance imaging. The results emphasize the importance of validating and sharing complex analysis workflows, and demonstrate the need for performing and reporting multiple analyses of the same data. Potential approaches that could be used to mitigate issues related to analytical variability are discussed., Depto. de Psicobiología y Metodología en Ciencias del Comportamiento, Fac. de Psicología, TRUE, pub

616.85 - Abstract
This thesis is presented in three parts. Part one reviews published studies utilising the 'trauma film paradigm'; an experimental analogue method for investigating the effect of pre-, peri-and post-trauma variables on PTSD symptomatology. It reports results from the reviewed trauma "film paradigm studies in relation to intrusive memories and compares these findings with clinical literature and cognitive processing models of PTSD. Part two presents the empirical paper; an investigation of the effect of rumination on analogue-PTSD intrusive memories and mood using the trauma film paradigm. Results indicate that both trauma-and non trauma-related rumination affects intrusions and negative mood. This was the first experimental study to specifically examine the role of rumination in the maintenance of symptoms. Findings support clinical research regarding the effects of rumination in persistent PTSD. The findings are presented in the context of theoretical explanations for the effect of rumination. Strengths and limitations of the study, as well as clinical implications, are discussed. Part three is a critical appraisal of the research study, which draws on the literature review presented in part one, and reflects in more detail on the methodological and conceptual strengths and limitations of the research. It also discusses the development of ideas underlying the study and the implications for future trauma film paradigm studies and clinical treatment.

Astrophysics - Abstract
Brown dwarfs are classified as objects which are not massive enough to sustain nuclear fusion of hydrogen, and are distinguished from planets by their ability to burn deuterium. Old (>10 Myr) brown dwarfs are expected to possess short-lived magnetic fields and, since they no longer generate energy from collapse and accretion, weak radio and X-ray emitting coronae. Several efforts have been undertaken in the past to detect chromospheric activity from the brown dwarf LP944-20 at X-ray and optical wavelengths, but only recently an X-ray flare from this object was detected. Here we report on the discovery of quiescent and flaring radio emission from this source, which represents the first detection of persistent radio emission from a brown dwarf, with luminosities that are several orders of magnitude larger than predicted from an empirical relation between the X-ray and radio luminosities of many stellar types. We show in the context of synchrotron emission, that LP944-20 possesses an unusually weak magnetic field in comparison to active dwarf M stars, which might explain the null results from previous optical and X-ray observations of this source, and the deviation from the empirical relations., Comment: Accepted to Nature

330.015195 - Abstract
This thesis addresses household saving behaviour, characterising the extent of self-insurance and public insurance over the life-cycle. Understanding how household saving varies in response to different forms of uncertainty is vitally important. Some risks are not fully insurable when markets are incomplete: for example, it is difficult for private insurers to cover layoff and productivity risk because of moral hazard issues. In these situations saving decisions determine households’ ability to avoid adversity, or to self-insure against such outcomes. While there has been substantial research into the broad questions concerning saving and expenditure choices, issues such as household asset allocation, the adequacy of self-insurance, and the interplay between these decisions and public insurance are less well understood. This thesis investigates these questions, combining theory and empirics in order to further our understanding of the underlying mechanisms of household saving choices. I begin with theory, presenting two structural papers that enrich the basic life-cycle model by increasing the realism of the modelling structure. In the first chapter I formulate a number of extensions to the standard framework, and detail how these permit simultaneous matching of key wealth and asset allocation statistics. In the second, I propose a novel identification strategy that enables us to elicit households’ beliefs about the risk and return of investing in stocks, and allows us to estimate intertemporal allocation parameters harmonising both consumption and financial wealth data. In the third chapter I undertake a reduced form approach to estimate the consumption loss associated with serious health shocks, using the life-cycle model as an organising framework. I develop a systemic analysis of household saving choices in order to better analyse questions about the effectiveness of self-insurance, the degree of preparedness for retirement, and how these respond to different levels of public insurance.

9. The course of Alzheimer's disease in adults with Down's syndrome : evidence for the early compromise of frontal lobe function

616.8 - Abstract
People with Down’s syndrome (DS) are known to be at very high risk of developing Alzheimer’s disease (AD) in middle-age. Recent research has suggested that the early presentation of dementia in this population may differ from the typical of AD in the general population, with the majority of the earliest changes occurring in personality or behaviour rather than in memory. The similarity of this clinical picture to that of Frontal Type Dementia (FTD) has led to the hypothesis that the functions of the frontal lobes are compromised early in the progression of AD in DS, perhaps as a consequence of the developmental abnormality of this brain region. Within this thesis, two studies are described that test this hypothesis. The first, involving the longitudinal follow-up of a previously identified population sample of older people with DS, examines progression in clinical presentation over time and the sequence of decline on measures of memory and executive function (EF; the cognitive processes associated with the frontal lobes). The second, a cross-sectional study in an expanded sample, examines in detail the relationship between early informant-reported changes and performance on an extensive battery of EF tests (developed specifically for use in this study) as well as on memory measures. The findings of both studies are supportive of the hypothesis outlined above. Individuals showing personality or behaviour changes at baseline were found to progress to the full clinical presentation of AD over time. In individuals without dementia, such changes were found to be related to poorer performance on EF but not memory measures, indicative of an early selective impairment in frontal lobe functioning. A model for the clinical course of dementia in DS is presented and the clinical implications of these findings are discussed, with particular reference to the assessment, diagnosis, management and treatment of dementia in this population.

11. Endocytosis and recycling of angiotensin II receptors

572 - Abstract
The main finding of this work is evidence that the AT
1 R is constitutively active and can undergo endocytosis and subsequent recycling in the absence of agonist. The application of a putative inverse agonist was able to increase the relative surface density in the presence of an inhibitor of novel protein synthesis. The internal pool partially colocalised with markers for early endosomes and the Golgi Apparatus, and was estimated to be 20% of the surface receptor density. This work has determined the presence of extracellular proteases that cleave the ang II into smaller peptide fragments within experimental assay timeframes. The putative cleavage product, ang III, was determined to induced AT1 R endocytosis if present in sufficient concentrations. Simple mathematical models have been used to describe the changes in the surface receptor number in the presence of drugs, one of which is the Two-compartment model’. This model assumes that there are only two compartments in which the receptor can exist, the plasma membrane and inside the cell. It ignores trafficking time via endosomes to intracellular organelles such as sorting endosomes and lysosomes. A modified version of the two-compartment model was derived to include agonist depletion by internalisation or degradation and the effect of a basal level of constitutive internalisation. This work has determined that the internalisation profile of the AT1 R can be fitted to the two-compartment model, although it is inadequate to describe the AT1 R recycling profile and suggests that there is more than one internal receptor recycling pool. This work has also attempted to perform a detailed characterisation of an AT1 R antagonist ZD 7155 in terms of receptor responses, and it effects upon ligand internalisation and receptor trafficking. It was concluded that insurmountable antagonism is a result of slow dissociation kinetics, but also may be due to residual antagonist during experimental procedures.- Published

- Abstract
Countries are increasingly looking to ‘digitalise’ how public services are delivered, with welfare‐to‐work and public employment services being key sites of reform. It is hoped that digitalisation can achieve efficient, effective, and targeted services for those in need and there is now a growing body of research on both the opportunities and pitfalls associated with this transition to digital welfare states. However, as a concept, ‘digitalisation’ remains ambiguously defined, hindering understanding of the distinct ways that discrete technological innovations are reshaping citizens' access to social protection and the role of street‐level discretion in welfare administration. Drawing on interviews with expert informants from three countries pioneering digital reforms, this study aims to better understand what digitalisation entails for the delivery of activation. We identify three discrete modes of ‘digitalisation’ in welfare‐to‐work programmes: virtual engagement (remote activation), transactional automation (self‐activation), and digital triaging (targeted activation). Far from digitalisation heralding the automation and curtailment of frontline discretion, the different modes reshape frontline delivery and citizens' access to social protection in specific ways.

- Abstract
Background: The emergency response to the COVID-19 pandemic has required a rapid acceleration of policy decision making, and raised a wide range of ethical issues worldwide, ranging from vaccine prioritisation, welfare and public health ‘trade-offs’, inequalities in policy impacts, and the legitimacy of scientific expertise. Aims and objectives: This paper explores the legacy of the pandemic for future science-advice-policy relationships by investigating how the UK government’s engagement with ethical advice is organised institutionally. We provide an analysis of some key ethical moments in the UK Government response to the pandemic, and institutions and national frameworks which exist to provide ethical advice on policy strategies. Methods: We draw on literature review, documentary analysis of scientific advisory group reports, and a stakeholder workshop with government ethics advisors and researchers in England. Findings: We identify how particular types of ethical advice and expertise are sought to support decision making. Contrary to a prominent assumption in the extensive literature on ‘governing by expertise’, ethical decisions in times of crisis are highly contingent. Discussion and conclusions: The paper raises an important set of questions for how best to equip policymakers to navigate decisions about values in situations characterised by knowledge deficits, complexity and uncertainty. We conclude that a clearer pathway is needed between advisory institutions and decision makers to ensure ethically-informed debate.

547 - Abstract
This thesis describes the syntheses and characterisations of new mono- and di-lithiated complexes of organic molecules of the general formula [(Rx-).xLi+].yL. The anion Rx- is either derived from a primary amine or is from a multifunctional organic molecule, containing one or more heteroatoms (usually N or S). The complexes have been prepared either by direct reaction of a simple amine with a metal source (solutions of nBuLi, tBuLi, LDA), or via a multi-stage reaction following an established synthetic organic protocol, attempt to isolate the lithiated intermediates at each stage. A variety of solvents, both hydrocarbon (toluene, hexane) and polar solvents (diethylether, THF), were used and all of the metallated complexes contain stoichiometric quantities of Lewis base donors, L (TMEDA, PMDETA, THF, Et2O). One mono-sodiated complex is also described. The work presented concentrates on the preparation and characterisation of new dilithiated complexes both in the solid state and in solution. The lithiated intermediates in many organic reactions provide a source of such dilithiated molecules. In general deprotonation of an organic acid, followed by insertion of a functional group (CS2, RCN) into the E-M bond (E=C, N; M=Li, Na) and in some cases further metallation, forms the basis of the reactions described. Chapter 1 provides a general introduction to the area of lithiated organics, with a brief review of X-ray structure analyses and solution studies on such complexes. In Chapter 2 the general experimental methods used to synthesise and characterise these complexes are described. Chapter 3 reports an investigation into an established synthetic protocol for the conversion of β-substituted N-containing heterocycles to their pyrrolo derivatives via metallation and nitrile insertion. Details of complexes 3-C5H4NCH=C(Ph)NHC(Ph)=NLi.PMDETA and 2,3-C5H4NCH=C(R)NX.xTHF ("problem") are provided where R=Ph or tBu and X=Li (L=THF) or X=H. The preparation and characterisation of the mono- and di-lithiated complexes of the related α-substituted pyridine derivatives are also described.

State response to assassination conspiracies is a reality behind diplomacy. This examination analyses British and American responses to assassination from the late 1960s to the mid-1980s. It argues the United States and Britain began with very different cultures of assassination. The 1980s was a period of structural convergence driven by practical collaboration: it had little to do with a longstanding ‘special relationship’, the Second Cold War, or relations between Margaret Thatcher and Ronald Reagan.

We present a measurement of the branching fraction for the decay of the neutral B meson into the final state J/psipi(+)pi(-). The data set contains approximately 56 x 10(6) BB pairs produced at the Upsilon(4S) resonance and recorded with the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) storage ring. The result of this analysis is B(B0-->J/psipi(+)pi(-))=(4.6+/-0.7+/-0.6) x 10(-5), where the first error is statistical and the second is systematic. In addition, we measure B(B0-->J/psirho(0))=(1.6+/-0.6+/-0.4) x 10(-5).

- Abstract
Alopecia areata (AA) is an autoimmune disease characterized by nonscarring hair loss. As a clinically heterogeneous disease, various classification systems have evolved for defining its severity. In this high-level review of the literature, we discuss the traditional classification systems for AA severity and their strengths and weaknesses. Most recent classifications have focused on the extent of scalp hair loss as a defining feature, but additional clinical aspects of the disease, including location, pattern, and duration of hair loss as well as impact on the patient's quality of life, are also relevant. These various components have typically been used unidimensionally to classify patients. We propose a multidimensional framework to define AA severity that incorporates multiple patient- and illness-related domains. Using such a framework, dermatologists may better assess the severity of the disease for the individual patient beyond the extent of hair loss.

- Abstract
The exercise of administrative discretion by street-level workers plays a key role in shaping citizens’ access to welfare and employment services. Governance reforms of social services delivery, such as performance-based contracting, have often been driven by attempts to discipline this discretion. In several countries, these forms of market governance are now being eclipsed by new modes of digital governance that seek to reshape the delivery of services using algorithms and machine learning. Australia, a pioneer of marketisation, is one example, proposing to deploy digitalisation to fully automate most of its employment services rather than as a supplement to face-to-face case management. We examine the potential and limits of this project to replace human-to-human with ‘machine bureaucracies’. To what extent are welfare and employment services amenable to digitalisation? What trade-offs are involved? In addressing these questions, we consider the purported benefits of machine bureaucracies in achieving higher levels of efficiency, accountability, and consistency in policy delivery. While recognising the potential benefits of machine bureaucracies for both governments and jobseekers, we argue that trade-offs will be faced between enhancing the efficiency and consistency of services and ensuring that services remain accessible and responsive to highly personalised circumstances.

- Abstract
Dramaturgical perspectives have been used successfully in the past by crisis management researchers. However, previous contributions have been limited because they have been actor‐centered, which has meant that they have tended to ignore the critical role that an audience can play in the drama of a crisis. This article therefore presents a “third act” in which dramaturgical perspectives are used to deliver an actor‐and‐audience centered analysis of crisis management. This third act is built around the dramaturgical concept of “characterization,” which we introduce to assess how an audience receives the symbolic outputs and discourses that are produced by crisis actors. After this theorizing, we present an analytical model, which will allow future researchers to analyze the interplay between actor, audience, and legitimacy when examining crisis. We conclude by illustrating the model's analytical capacity via an examination of the role of leaders and experts during the COVID‐19 pandemic.

- Abstract
BACKGROUND: Education is broader than academic teaching. It includes teaching students social-emotional skills both directly and indirectly through a positive school climate. OBJECTIVE: To evaluate if a universal school-based mindfulness training (SBMT) enhances teacher mental health and school climate. METHODS: The My Resilience in Adolescence parallel group, cluster randomised controlled trial (registration: ISRCTN86619085; funding: Wellcome Trust (WT104908/Z/14/Z, WT107496/Z/15/Z)) recruited 85 schools (679 teachers) delivering social and emotional teaching across the UK. Schools (clusters) were randomised 1:1 to either continue this provision (teaching as usual (TAU)) or include universal SBMT. Data on teacher mental health and school climate were collected at prerandomisation, postpersonal mindfulness and SBMT teacher training, after delivering SBMT to students, and at 1-year follow-up. FINDING: Schools were recruited in academic years 2016/2017 and 2017/2018. Primary analysis (SBMT: 43 schools/362 teachers; TAU: 41 schools/310 teachers) showed that after delivering SBMT to students, SBMT versus TAU enhanced teachers' mental health (burnout) and school climate. Adjusted standardised mean differences (SBMT minus TAU) were: exhaustion (-0.22; 95% CI -0.38 to -0.05); personal accomplishment (-0.21; -0.41, -0.02); school leadership (0.24; 0.04, 0.44); and respectful climate (0.26; 0.06, 0.47). Effects on burnout were not significant at 1-year follow-up. Effects on school climate were maintained only for respectful climate. No SBMT-related serious adverse events were reported. CONCLUSIONS: SBMT supports short-term changes in teacher burnout and school climate. Further work is required to explore how best to sustain improvements. CLINICAL IMPLICATIONS: SBMT has limited effects on teachers' mental and school climate. Innovative approaches to support and preserve teachers' mental health and school climate are needed.

- Abstract
BACKGROUND: Preventing mental health problems in early adolescence is a priority. School-based mindfulness training (SBMT) is an approach with mixed evidence. OBJECTIVES: To explore for whom SBMT does/does not work and what influences outcomes. METHODS: The My Resilience in Adolescence was a parallel-group, cluster randomised controlled trial (K=84 secondary schools; n=8376 students, age: 11-13) recruiting schools that provided standard social-emotional learning. Schools were randomised 1:1 to continue this provision (control/teaching as usual (TAU)), and/or to offer SBMT ('.b' (intervention)). Risk of depression, social-emotional-behavioural functioning and well-being were measured at baseline, preintervention, post intervention and 1 year follow-up. Hypothesised moderators, implementation factors and mediators were analysed using mixed effects linear regressions, instrumental variable methods and path analysis. FINDINGS: SBMT versus TAU resulted in worse scores on risk of depression and well-being in students at risk of mental health problems both at post intervention and 1-year follow-up, but differences were small and not clinically relevant. Higher dose and reach were associated with worse social-emotional-behavioural functioning at postintervention. No implementation factors were associated with outcomes at 1-year follow-up. Pregains-postgains in mindfulness skills and executive function predicted better outcomes at 1-year follow-up, but the SBMT was unsuccessful to teach these skills with clinical relevance.SBMT as delivered in this trial is not indicated as a universal intervention. Moreover, it may be contraindicated for students with existing/emerging mental health symptoms. CLINICAL IMPLICATIONS: Universal SBMT is not recommended in this format in early adolescence. Future research should explore social-emotional learning programmes adapted to the unique needs of young people.

- Abstract
BACKGROUND: Systematic reviews suggest school-based mindfulness training (SBMT) shows promise in promoting student mental health. OBJECTIVE: The My Resilience in Adolescence (MYRIAD) Trial evaluated the effectiveness and cost-effectiveness of SBMT compared with teaching-as-usual (TAU). METHODS: MYRIAD was a parallel group, cluster-randomised controlled trial. Eighty-five eligible schools consented and were randomised 1:1 to TAU (43 schools, 4232 students) or SBMT (42 schools, 4144 students), stratified by school size, quality, type, deprivation and region. Schools and students (mean (SD); age range=12.2 (0.6); 11-14 years) were broadly UK population-representative. Forty-three schools (n=3678 pupils; 86.9%) delivering SBMT, and 41 schools (n=3572; 86.2%) delivering TAU, provided primary end-point data. SBMT comprised 10 lessons of psychoeducation and mindfulness practices. TAU comprised standard social-emotional teaching. Participant-level risk for depression, social-emotional-behavioural functioning and well-being at 1 year follow-up were the co-primary outcomes. Secondary and economic outcomes were included. FINDINGS: Analysis of 84 schools (n=8376 participants) found no evidence that SBMT was superior to TAU at 1 year. Standardised mean differences (intervention minus control) were: 0.005 (95% CI -0.05 to 0.06) for risk for depression; 0.02 (-0.02 to 0.07) for social-emotional-behavioural functioning; and 0.02 (-0.03 to 0.07) for well-being. SBMT had a high probability of cost-effectiveness (83%) at a willingness-to-pay threshold of £20 000 per quality-adjusted life year. No intervention-related adverse events were observed. CONCLUSIONS: Findings do not support the superiority of SBMT over TAU in promoting mental health in adolescence. CLINICAL IMPLICATIONS: There is need to ask what works, for whom and how, as well as considering key contextual and implementation factors.

- Abstract
BACKGROUND: Anxiety disorders are common among primary-school aged children, but few affected children receive evidence-based treatment. Identifying and supporting children who experience anxiety problems through schools would address substantial treatment access barriers that families and school staff often face. We have worked with families and school staff to co-design procedures that incorporate screening, feedback for parents, and the offer of a brief intervention in primary schools. This study sets out to assess the feasibility of a subsequent school-based cluster randomised controlled trial to evaluate these procedures. Our objectives are to ensure our procedures for identifying and supporting children with anxiety difficulties through primary schools are acceptable and there are no negative impacts, to estimate recruitment and retention rates, and to identify any changes needed to study procedures or measures. METHODS: We will recruit six primary/junior schools in England (2 classes per school), and invite all children (aged 8-9) (n = 360) and their parent/carer and class teacher in participating classes to take part. Children, parents and class teachers will complete questionnaires at baseline and 12-week follow-up. Children who 'screen positive' on a 2-item parent-report child anxiety screen at baseline will be the target population (expected n = 43). Parents receive feedback on screening questionnaire responses, and where the child screens positive the family is offered support (OSI: Online Support and Intervention for child anxiety). OSI is a brief, parent-led online intervention, supported by short telephone sessions with a Children's Wellbeing Practitioner. Participants' experiences of study procedures will be assessed through qualitative interviews/discussion groups. DISCUSSION: Evidence-based procedures for identifying and supporting children with anxiety difficulties through primary schools would improve children's access to timely, effective interv

- Abstract
BACKGROUND: Systematically screening for child anxiety problems, and offering and delivering a brief, evidence-based intervention for children who are identified as likely to benefit would minimise common barriers that families experience in accessing treatment. We have developed a short parent-report child anxiety screening questionnaire, and procedures for administering screening questionnaires, sharing screening outcomes with families, and offering and delivering a brief parent-led online intervention (OSI: Online Support and Intervention for child anxiety) through schools. This trial aims to evaluate clinical and health economic outcomes for (1) children (aged 8-9) who screen positive for anxiety problems at baseline (target population) and (2) the wider population of all children in participating classes (total population) in schools randomly allocated to receive identification-to-intervention procedures and usual school practice ('screening and intervention'), compared to assessment and usual school practice only ('usual school practice'). METHODS: The trial design is a parallel-group, superiority cluster randomised controlled trial, with schools (clusters) randomised to 'screening and intervention' or 'usual school practice' arms in a 1:1 ratio stratified according to the level of deprivation within the school. We will recruit schools and participants in two phases (a pilot phase (Phase 1) and Phase 2), with progression criteria assessed prior to progressing to Phase 2. In total, the trial will recruit 80 primary/junior schools in England, and 398 children (199 per arm) who screen positive for anxiety problems at baseline (target population). In schools allocated to 'screening and intervention': (1) parents/carers will complete a brief parent-report child anxiety screening questionnaire (at baseline) and receive feedback on their child's screening outcomes (after randomisation), (2) classes will receive a lesson on managing fears and worries and staff will b

Introduction The COVID-19 pandemic has influenced the delivery of healthcare. In accordance with the UK Joint Royal Colleges’ advice the management of acute appendicitis (AA) changed with greater consideration for non-operative management (NOM) or open appendicectomy where operative management (OM) s sought. Our aim is to share our experience of the presentation, management and outcomes for patients presenting to our Trust with AA to guide care for future viral pandemics. Methods This single-centre retrospective cohort study included patients diagnosed with AA in March to July 2019 compared with March to July 2020. Medical records were used to evaluate demographics, inflammatory markers, imaging, severity, management, histology, length of stay (LOS), complications and 90-day outcomes. Results There were 149 and 125 patients in the 2019 and 2020 cohort, respectively. 14 patients (9.4%) had NOM in 2019 versus 31 patients (24.8%) in 2020 (p = 0.001). In the 2019 OM group 125 patients (92.6%) had laparoscopic appendicectomy versus 69 (73.4%) in 2020. 59 patients (39.6%) had a CT in 2019 versus 70 (56%) in 2020. The median LOS was 4 days (interquartile range (IQR) 3 to 6 days) in 2019 and 3 days (IQR 2 to 5 days) in 2020 (p = 0.03). Two patients in each year who received NOM had treatment failure (14.3% in 2019 and 6.5% in 2020). Three patients in 2019 who had OM had treatment failure (2.2%). Of 95 patients tested for COVID-19 all but one was negative. Conclusion During the COVID-19 pandemic there was no observed increase in severity of AA, patients had a shorter LOS and were more likely to have imaging. NOM proportionally increased with no observed change in outcomes.
