White adults' color-evasive racial attitudes and racism emotionality: Understanding patterns and correlates.

There is limited empirical work that examines how Whites psychologically maintain and make efforts to dismantle systemic racism. Prior work suggests that both color-evasive attitudes and aspects of racism emotionality predict Whites' behaviors and, to a lesser extent, their well-being as their racial position is challenged. Utilizing a sample of 897 White adults attending college (Mage = 22.98 years, SD = 5.95), the present study examined how color-evasive attitudes (i.e., blatant racial issues, racial privilege, and awareness of institutional discrimination), diversity attitudes (anti-Blackness attitudes, openness to diversity), and racism emotionality (i.e., white empathy, white guilt, and fear) co-occur together to meaningfully predict Whites' indicators of well-being (i.e., depressive and anxiety symptoms, perceived stress, and life satisfaction). Latent profile analysis revealed four profiles that varied from more antiracist configurations (abandoning racism profiles, 71% of the sample) to more racist configurations (internalizing racism profiles, 29% of sample). White individuals within the antiracist configuration displayed the highest levels of depressive and anxiety symptoms, perceived stress, and lowest levels of life satisfaction. While those in the internalizing racism configuration displayed statistically higher reports of satisfaction with life and lowest levels of depression, anxiety, and stress. Findings suggest that understanding the combined experiences of color-evasive attitudes and racism emotionality for Whites are important avenues for increasing responsibility and taking accountability in dismantling racism.

Self-Assembly of Nanocrystalline Structures from Freestanding Oxide Membranes.

The exploration of crystalline nanostructures enhances the understanding of quantum phenomena occurring in spatially confined quantum matter and may lead to functional materials with unforeseen applications. A novel route to fabricating nanocrystalline oxide structures of exceptional quality is presented. This is achieved by utilizing a self-assembly process of ultrathin membranes composed of the desired oxide. The thermally induced self-assembly of nanocrystalline structures is driven by dewetting the oxide membranes once they are lifted off and transferred onto sapphire surfaces. In three successive steps, the process provides nanovoids, nanowires, and nanocrystals. Regardless of substrate orientation, the nanostructures are highly anisotropic in shape due to material retraction favoring low-index crystalline lattice directions of the membranes. The orientation of the nanostructures is provided precisely by the crystal lattice of the transferred membrane. The microstructure of the nanocrystals exhibits exceptional quality, characterized by a pristine crystal structure and uniform stoichiometry, both maintained all the way down to the well-developed crystalline facets. The demonstrated self-assembly process holds the potential to improve the understanding of surface diffusion phenomena at the interface of materials, which is important for advancing epitaxial growth technology and paves the way to fabricating crystalline nanostructures by the transfer and self-assembly of membranes.

Development of a support for Black Lives Matter measure among racially-ethnically diverse college students.

This paper developed and validated a new measure of support for the Black Lives Matter (BLM) movement among a racially-ethnically diverse sample of college students. The measure focuses on the movement's principles of Black liberation, intersectionality, and alliance building. Participants included 1934 college students (75% female) from a large public Southwestern university. The factor structure was supported by exploratory and confirmatory factor analyses, resulting in an 18-item measure, Support for Black Lives Matter, with two underlying factors. Black Liberation includes 12 items representing support for BLM because of awareness of and challenging structural inequality and racism experienced by Black individuals. Intersectional Values includes six items representing support for BLM because it embraces and affirms marginalized populations within the Black community, especially disabled Blacks, queer Blacks, Black women, and Black families with children. Evidence of criterion-related validity was demonstrated with racial group differences in support of BLM factors. Evidence of convergent validity was supported by significant positive correlations between support for BLM factors and critical consciousness (including awareness of racism, classism, and heterosexism), and negative correlations between support for BLM factors and subtle racist attitudes toward Blacks. Measurement invariance was evident between White, Black, Asian American, Latinx, and Multiracial participants. Implications and suggestions for use of the new measure are discussed.

Mechanisms and pathways to impact in public health research: a preliminary analysis of research funded by the National Institute for Health Research (NIHR).

BACKGROUND: The mechanisms and pathways to impacts from public health research in the UK have not been widely studied. Through the lens of one funder (NIHR), our aims are to map the diversity of public health research, in terms of funding mechanisms, disciplinary contributions, and public health impacts, identify examples of impacts, and pathways to impact that existing reporting mechanisms may not otherwise have captured, and provide illustrations of how public health researchers perceive the generation of non-academic impact from their work. METHODS: A total of 1386 projects were identified as 'public health research' by the NIHR and listed in the NIHR Public Health Overview database (2000-2016). From these, a subset of 857 projects were matched as potentially having begun reporting impacts via an external data-gathering platform (Researchfish). Data on the 857 projects were analyzed quantitatively, and nine projects were selected to investigate further through semi-structured interviews with principal investigators. Two workshops took place to validate emerging and final findings and facilitate analysis. RESULTS: In addition to the NIHR School for Public Health Research and the NIHR Public Health Research Programme, 89% of projects contained in the NIHR Public Health Overview portfolio as 'public health research' are funded via other NIHR research programmes, suggesting significant diversity in disciplines contributing to public health research and outcomes. The pathways to impact observed in our in-depth case studies include contributing to debates on what constitutes appropriate evidence for national policy change, acknowledging local 'unintended' impacts, building trusted relationships with stakeholders across health and non-health sectors and actors, collaborating with local authorities, and using non-academic dissemination channels. CONCLUSIONS: Public health as a discipline contributes substantially to impact beyond academia. To support the diversity of these impacts, we need to recognise localized smaller-scale impacts, and the difference in types of evidence required for community and local authority-based impacts. This will also require building capacity and resources to enable impact to take place from public health research. Finally, support is required for engagement with local authorities and working with non-health sectors that contribute to health outcomes.

Innovation as a Driver of Quality and Productivity in UK Healthcare: Creating and Connecting Receptive Places-Emerging Insights.

The demand for health services in England is both growing and changing in nature, yet resources are limited in their ability to respond to the scale and scope of need. As a result, the NHS is under increasing pressures to realise productivity gains, while continuing to deliver high quality care. RAND Europe and the University of Manchester have been commissioned to conduct a study to examine the potential of innovation to respond to the challenges the NHS faces, and to help deliver value for money, efficient and effective services. "Innovation" in this study refers to any product, technology or service that is new to the NHS, or applied in a new way, aimed at delivering affordable and improved care. The learning we have gained adds considerable depth to the practical discussions presented regarding how innovation can be first nurtured and then made meaningful and actionable in a variety of settings. This is important given the complexity of health innovation systems and the diversity of elements that need to interact and work together for the overall system to function effectively. We share insights related to skills, capabilities and leadership; motivations and accountabilities; information and evidence; relationships and networks; patient and public engagement; and funding and commissioning. We will develop these detailed learning points into a more systematic analysis as the research evolves. The research is funded by the Department of Health Policy Research Programme, in close collaboration with NHS England and the Office of Life Sciences.

How policy can help develop and sustain workforce capacity in UK dementia research: insights from a career tracking analysis and stakeholder interviews.

OBJECTIVES: To identify research support strategies likely to be effective for strengthening the UK's dementia research landscape and ensuring a sustainable and competitive workforce. DESIGN: Interviews and qualitative analysis; systematic internet search to track the careers of 1500 holders of UK doctoral degrees in dementia, awarded during 1970-2013, to examine retention in this research field and provide a proxy profile of the research workforce. SETTING AND PARTICIPANTS: 40 interviewees based in the UK, whose primary role is or has been in dementia research (34 individuals), health or social care (3) or research funding (3). Interviewees represented diverse fields, career stages and sectors. RESULTS: While the UK has diverse strengths in dementia research, needs persist for multidisciplinary collaboration, investment in care-related research, supporting research-active clinicians and translation of research findings. There is also a need to better support junior and midlevel career opportunities to ensure a sustainable research pipeline and future leadership. From a sample of 1500 UK doctorate holders who completed a dementia-related thesis in 1970-2013, we identified current positions for 829 (55%). 651 (43% of 1500) could be traced and identified as still active in research (any field) and 315 (21%) as active in dementia research. Among recent doctoral graduates, nearly 70% left dementia research within 4-6 years of graduation. CONCLUSIONS: A dementia research workforce blueprint should consider support for individuals, institutions and networks. A mix of policy interventions are needed, aiming to attract and retain researchers; tackle bottlenecks in career pathways, particularly at early and midcareer stages (eg, scaling-up fellowship opportunities, rising star programmes, bridge-funding, flexible clinical fellowships, leadership training); and encourage research networks (eg, doctoral training centres, succession and sustainability planning). Interventions should also address the need for coordinated investment to improve multidisciplinary collaboration; balanced research portfolios across prevention, treatment and care; and learning from evaluation.

The use and impact of quality of life assessment tools in clinical care settings for cancer patients, with a particular emphasis on brain cancer: insights from a systematic review and stakeholder consultations.

PURPOSE: Patient-reported data are playing an increasing role in health care. In oncology, data from quality of life (QoL) assessment tools may be particularly important for those with limited survival prospects, where treatments aim to prolong survival while maintaining or improving QoL. This paper examines the use and impact of using QoL measures on health care of cancer patients within a clinical setting, particularly those with brain cancer. It also examines facilitators and challenges, and provides implications for policy and practice. DESIGN: We conducted a systematic literature review, 15 expert interviews and a consultation at an international summit. RESULTS: The systematic review found no relevant intervention studies specifically in brain cancer patients, and after expanding our search to include other cancers, 15 relevant studies were identified. The evidence on the effectiveness of using QoL tools was inconsistent for patient management, but somewhat more consistent in favour of improving patient-physician communication. Interviews identified unharnessed potential and growing interest in QoL tool use and associated challenges to address. CONCLUSION: Our findings suggest that the use of QoL tools in cancer patients may improve patient-physician communication and have the potential to improve care, but the tools are not currently widely used in clinical practice (in brain cancer nor some other cancer contexts) although they are in clinical trials. There is a need for further research and stakeholder engagement on how QoL tools can achieve most impact across cancer and patient contexts. There is also a need for policy, health professional, research and patient communities to strengthen information exchange and debate, support awareness raising and provide training on tool design, use and interpretation.

The International AIDS Vaccine Initiative's Capacity Building Activities in East Africa: Evaluating Progress and Impacts in Kenya, Uganda and Rwanda.

The International AIDS Vaccine Initiative (IAVI) is one of a number of Product Development Partnerships created to bridge the gap between scientific and technological potential and the needs of low income populations in low and middle income countries. Specifically IAVI is focused on creating a preventative vaccine for HIV/AIDS. Whilst the remit of IAVI is to create new science, technology and products, its work necessarily involves a wide range of stakeholders and different constituencies in industrially developing and developed countries. Its capacity building activities relate to strengthening the ability to conduct clinical trials and are broad based, spanning scientific and technological capacity through to organisational, advocacy and broader development capabilities. The aim of this study was to deepen IAVI's understanding of how it contributes to capacity building activities in East Africa (Uganda, Kenya and Rwanda), spanning scientific and technological capacity through to organisational, advocacy and broader development capabilities. IAVI's mission to develop an HIV vaccine has become increasingly connected to wider health systems strengthening, through its clinical research activities in East Africa. Since it began its operations in the region, IAVI has made a significant contribution to training interventions to support scientific excellence and good clinical practice and invested in infrastructure and laboratories at Clinical Research Centres in East Africa. Although clear challenges still exist with ensuring sustained investment, accessing marginalized populations and demonstrating progress in capacity building, the experiences of IAVI to date suggest that substantial progress is being made towards wider health systems strengthening in the region.

Mapping the Global Mental Health Research Funding System.

This study maps the global funding of mental health research between 2009 and 2014. It builds from the bottom up a picture of who the major funders are, what kinds of research they support and how their strategies relate to one another. It uses the funding acknowledgements on journal papers as a starting point for this. The study also looks to the future, considering some of the areas of focus, challenges and opportunities which may shape the field in the coming few years.

UK Doubles Its "World-Leading" Research in Life Sciences and Medicine in Six Years: Testing the Claim?

BACKGROUND: The UK, like some other countries, carries out a periodic review of research quality in universities and the most recent Research Excellence Framework (REF) reported a doubling (103% increase) in its "world leading" or so-called "4*" research outputs in the areas of life sciences and medicine between 2008 and 2014. This is a remarkable improvement in six years and if validated internationally could have profound implications for health sciences. METHODS: We compared the reported changes in 4* quality to bibliometric measures of quality for the 56,639 articles submitted to the RAE 2008 and the 50,044 articles submitted to the REF 2014 to Panel A, which assesses the life sciences, including medicine. FINDINGS: UK research submitted to the RAE and REF was of better quality than worldwide research on average. While we found evidence for some increase in the quality of top UK research articles, a 10-25% increase in the top 10%ile papers, depending upon the metrics used, we could not find evidence to support a 103% increase in quality. Instead we found that as compared to the RAE, the REF results implied a lower citation %ile threshold for declaring a 4*. INTERPRETATION: There is a wide discrepancy between bibliometric indices and peer-review panel judgements between the RAE 2008 and REF 2014. It is possible that the changes in the funding regime between 2008 and 2014 that significantly increased the financial premium for 4* articles may have influenced research quality evaluation. For the advancement of science and health, evaluation of research quality requires consistency and validity - the discrepancy noted here calls for a closer examination of mass peer-review methods like the REF.

The future of anticoagulation management in atrial fibrillation in Europe: An assessment of today's challenges with recommendations for the future.

Atrial fibrillation (AF) is the most common type of cardiac arrhythmia, affecting approximately 1-2 per cent of the population worldwide. Those who suffer from AF have a five times higher risk of stroke. AF prevalence increases with age and it affects roughly 18 per cent of the population over 85. Consequently, as populations age, AF is becoming an increasingly significant public health issue. Over recent years there have been developments in treatment and management options, both for treating the arrhythmia directly, and assessing and reducing the risk of AF-related stroke, but there is a need to ensure that available knowledge is applied optimally to benefit patients so that opportunities to prevent AF-related stroke are not missed. The aims of this project were to assess the current landscape and explore the direction of future developments in AF management in Europe, with a focus on the use of anticoagulants in the prevention of AF-related stroke. Through rapid evidence assessment, key informant interviews, PESTLE analysis and the development and exploration of future scenarios, we have developed sets of shorter- and longer-term recommendations for improving AF-related patient outcomes. The short-term recommendations are: i) improve AF awareness among the public and policymakers; ii) support education about AF management for healthcare professionals and patients; and iii) maintain engagement in AF-related research across the health services.

Maximum likelihood inference of small trees in the presence of long branches.

The statistical basis of maximum likelihood (ML), its robustness, and the fact that it appears to suffer less from biases lead to it being one of the most popular methods for tree reconstruction. Despite its popularity, very few analytical solutions for ML exist, so biases suffered by ML are not well understood. One possible bias is long branch attraction (LBA), a regularly cited term generally used to describe a propensity for long branches to be joined together in estimated trees. Although initially mentioned in connection with inconsistency of parsimony, LBA has been claimed to affect all major phylogenetic reconstruction methods, including ML. Despite the widespread use of this term in the literature, exactly what LBA is and what may be causing it is poorly understood, even for simple evolutionary models and small model trees. Studies looking at LBA have focused on the effect of two long branches on tree reconstruction. However, to understand the effect of two long branches it is also important to understand the effect of just one long branch. If ML struggles to reconstruct one long branch, then this may have an impact on LBA. In this study, we look at the effect of one long branch on three-taxon tree reconstruction. We show that, counterintuitively, long branches are preferentially placed at the tips of the tree. This can be understood through the use of analytical solutions to the ML equation and distance matrix methods. We go on to look at the placement of two long branches on four-taxon trees, showing that there is no attraction between long branches, but that for extreme branch lengths long branches are joined together disproportionally often. These results illustrate that even small model trees are still interesting to help understand how ML phylogenetic reconstruction works, and that LBA is a complicated phenomenon that deserves further study.

Amino acid changes in disease-associated variants differ radically from variants observed in the 1000 genomes project dataset.

The 1000 Genomes Project data provides a natural background dataset for amino acid germline mutations in humans. Since the direction of mutation is known, the amino acid exchange matrix generated from the observed nucleotide variants is asymmetric and the mutabilities of the different amino acids are very different. These differences predominantly reflect preferences for nucleotide mutations in the DNA (especially the high mutation rate of the CpG dinucleotide, which makes arginine mutability very much higher than other amino acids) rather than selection imposed by protein structure constraints, although there is evidence for the latter as well. The variants occur predominantly on the surface of proteins (82%), with a slight preference for sites which are more exposed and less well conserved than random. Mutations to functional residues occur about half as often as expected by chance. The disease-associated amino acid variant distributions in OMIM are radically different from those expected on the basis of the 1000 Genomes dataset. The disease-associated variants preferentially occur in more conserved sites, compared to 1000 Genomes mutations. Many of the amino acid exchange profiles appear to exhibit an anti-correlation, with common exchanges in one dataset being rare in the other. Disease-associated variants exhibit more extreme differences in amino acid size and hydrophobicity. More modelling of the mutational processes at the nucleotide level is needed, but these observations should contribute to an improved prediction of the effects of specific variants in humans.

RARalpha-PLZF overcomes PLZF-mediated repression of CRABPI, contributing to retinoid resistance in t(11;17) acute promyelocytic leukemia.

Leukemia-associated chimeric oncoproteins often act as transcriptional repressors, targeting promoters of master genes involved in hematopoiesis. We show that CRABPI (encoding cellular retinoic acid binding protein I) is a target of PLZF, which is fused to RARalpha by the t(11;17)(q23;q21) translocation associated with retinoic acid (RA)-resistant acute promyelocytic leukemia (APL). PLZF represses the CRABPI locus through propagation of chromatin condensation from a remote intronic binding element culminating in silencing of the promoter. Although the canonical, PLZF-RARalpha oncoprotein has no impact on PLZF-mediated repression, the reciprocal translocation product RARalpha-PLZF binds to this remote binding site, recruiting p300, inducing promoter hypomethylation and CRABPI gene up-regulation. In line with these observations, RA-resistant murine PLZF/RARalpha+RARalpha/PLZF APL blasts express much higher levels of CRABPI than standard RA-sensitive PML/RARalpha APL. RARalpha-PLZF confers RA resistance to a retinoid-sensitive acute myeloid leukemia (AML) cell line in a CRABPI-dependent fashion. This study supports an active role for PLZF and RARalpha-PLZF in leukemogenesis, identifies up-regulation of CRABPI as a mechanism contributing to retinoid resistance, and reveals the ability of the reciprocal fusion gene products to mediate distinct epigenetic effects contributing to the leukemic phenotype.
