    Government policies attempt to mitigate the economic risks to households of major life transitions. This paper focuses on two such transitions that social security systems typically insure against—long term exits from the labor market (retirement, disability, unemployment insurance) and the death of a household head or spouse (survivor’s insurance). We examine labor force exits of men at various ages in four countries--Canada, Germany, Great Britain, and the United States—using data from the Cross-National Equivalent File, a matched longitudinal data set. We focus on how average net-of-tax household income changes in the years before and after the event. We find that when one measures the change in economic well-being following a labor market exit by the fraction of lost labor earnings replaced by social security income, the decline in the household’s economic well-being is substantially overstated. When we compare net-of-tax household income before and after a long term exit from the labor market, we find that such drops are much less than those implied by a social security replacement rate and that differences across countries in the average drop are much less than those based on a social security replacement rate. We find the same pattern when we focus on how net-of-tax household income changes in the years before and after the death of a head or spouse. Declines in net-of-tax household income following such a death are much lower than the decline implied by a replacement of the deceased person’s labor earnings and social security benefits by their household’s post-death social security income. But the size of the change in individualized net-of-tax income following the death of a head or spouse is greatly affected by assumptions used to adjust for changes in household size.

    The Alleviate Advanced Pain Discovery Platform Data Hub:A national resource for accessing and sharing pain data

    Get PDF
    There are many clinical and non-clinical datasets investigating pain that have been collected by researchers over many years, however, finding and getting access to them is challenging. The data are siloed in hard-to-reach places, in non-standard formats, and it is not possible to assess how relevant they are before getting access. This is a barrier to the pain research community and results in duplication of effort. It does not have to be this way and there are alternative solutions available. Alleviate is an HDR UK Data Hub for the federated querying and secure sharing of UK pain data to researchers, analysts and clinicians at a national and international level. Alleviate is the Data Hub for the Advanced Pain Discovery Platform (APDP), a ÂŁ24 million research initiative to break through the complexity of pain and reveal potential new treatment approaches to address a wide spectrum of chronic and debilitating clinical conditions

    Complex Challenges and New Opportunities: Building the Framework for Boundary Review. An Assessment of PPS’s Organizational Readiness and Options for Citizen Engagement

    Get PDF
    On February 25, 2013, the PPS Board unanimously approved Resolution 4718, which directs staff “to develop and recommend a process for a comprehensive review of school boundaries district-wide and policies related to student assignment and transfer to better align with the Racial Educational Equity Policy and promote strong capture rates and academic programs at every grade level.” To deal with the student assignment and transfer policy issues, Superintendent Carole Smith charged the “Superintendent’s Advisory Committee on Enrollment and Transfer” (SACET) with recommending changes to student assignment and transfer policies to bring them into alignment with the district’s racial educational equity policy. As for the Districtwide Boundary Review component, in December 2013, Portland Public Schools entered into an Intergovernmental Agreement with the Center for Public Service (CPS) at Portland State University (PSU) to assist the District with eventually achieving two important tasks: Devise and implement a process to engage a wide range of current and future PPS parents, students and staff, community organizations; and other key stakeholders to conduct a comprehensive District-wide Boundary Review and recommend new PPS school boundaries for adoption by the Portland School Board; Create a flexible and dynamic “Boundary Review Framework” on which the current and future boundary-setting processes will be based. CPS proposed a three-phase approach for the “PPS District-Wide Boundary Framework” project, which would include recommendations at the end of each Phase as to recommended next steps. As initially outlined from the vantage point of October 2013, the proposed approach would be as follows: Phase I (3 months): Initial Assessment and Framework Recommendations Phase II (7-8 months): Stakeholder and Community Engagement Phase III (4 months): Final Recommendations, Community Deliberations, and Decision Making This report concludes Phase I and includes the Findings and Recommendations from our Initial Assessment

    Development and Characterisation of a Human Chronic Skin Wound Cell Line:Towards an Alternative for Animal Experimentation

    Get PDF
    Background: Chronic skin wounds are a growing financial burden for healthcare providers, causing discomfort/immobility to patients. Whilst animal chronic wound models have been developed to allow for mechanistic studies and to develop/test potential therapies, such systems are not good representations of the human chronic wound state. As an alternative, human chronic wound fibroblasts (CWFs) have permitted an insight into the dysfunctional cellular mechanisms that are associated with these wounds. However, such cells strains have a limited replicative lifespan and therefore a limited reproducibility/usefulness. Objectives: To develop/characterise immortalised cell lines of CWF and patient-matched normal fibroblasts (NFs). Methods and Results: Immortalisation with human telomerase resulted in both CWF and NF proliferating well beyond their replicative senescence end-point (respective cell strains senesced as normal). Gene expression analysis demonstrated that, whilst proliferation-associated genes were up-regulated in the cell lines (as would be expected), the immortalisation process did not significantly affect the disease-specific genotype. Immortalised CWF (as compared to NF) also retained a distinct impairment in their wound repopulation potential (in line with CWF cell strains). Conclusions: These novel CWF cell lines are a credible animal alternative and could be a valuable research tool for understanding both the aetiology of chronic skin wounds and for therapeutic pre-screening

    Unregulated actin polymerization by WASp causes defects of mitosis and cytokinesis in X-linked neutropenia

    Get PDF
    Specific mutations in the human gene encoding the Wiskott-Aldrich syndrome protein (WASp) that compromise normal auto-inhibition of WASp result in unregulated activation of the actin-related protein 2/3 complex and increased actin polymerizing activity. These activating mutations are associated with an X-linked form of neutropenia with an intrinsic failure of myelopoiesis and an increase in the incidence of cytogenetic abnormalities. To study the underlying mechanisms, active mutant WASpI294T was expressed by gene transfer. This caused enhanced and delocalized actin polymerization throughout the cell, decreased proliferation, and increased apoptosis. Cells became binucleated, suggesting a failure of cytokinesis, and micronuclei were formed, indicative of genomic instability. Live cell imaging demonstrated a delay in mitosis from prometaphase to anaphase and confirmed that multinucleation was a result of aborted cytokinesis. During mitosis, filamentous actin was abnormally localized around the spindle and chromosomes throughout their alignment and separation, and it accumulated within the cleavage furrow around the spindle midzone. These findings reveal a novel mechanism for inhibition of myelopoiesis through defective mitosis and cytokinesis due to hyperactivation and mislocalization of actin polymerization

    Can reductions in water residence time be used to disrupt seasonal stratification and control internal loading in a eutrophic monomictic lake?

    Anthropogenic eutrophication caused by excess loading of nutrients, especially phosphorus (P), from catchments is a major cause of lake water quality degradation. The release of P from bed sediments to the water column, termed internal loading, can exceed catchment P load in eutrophic lakes, especially those that stratify during warm summer periods. Managing internal P loading is challenging, and although a range of approaches have been implemented, long-term success is often limited, requiring lake-specific solutions. Here, we assess the manipulation of lake residence time to inhibit internal loading in Elterwater, a shallow stratifying lake in the English Lake District, UK. Since 2016, additional inflowing water has been diverted into the inner basin of Elterwater to reduce its water residence time, with the intention of limiting the length of the stratified period and reducing internal loading. Combining eight years of field data in a Before-After-Control-Impact study with process-based hydrodynamic modelling enabled the quantification of the residence time intervention effects on stratification length, water column stability, and concentrations of chlorophyll a and P. Annual water residence time was reduced during the study period by around 40% (4.9 days). Despite this change, the lake continued to stratify and developed hypolimnetic anoxia. As a result, there was little significant change in phosphorus (as total or soluble reactive phosphorus) or chlorophyll a concentrations. Summer stratification length was 2 days shorter and 7% less stable with the intervention. Our results suggest that the change to water residence time in Elterwater was insufficient to induce large enough physical changes to improve water quality. However, the minor physical changes suggest the management measure had some impact and that larger changes in water residence time may have the potential to induce reductions in internal loading. Future assessments of management requirements should combine multi-year observations and physical lake modelling to provide improved understanding of the intervention effect size required to alter the physical structure of the lake, leading to increased hypolimnetic oxygen and reduced potential for internal loading

    A randomised trial of the effect of omega-3 polyunsaturated fatty acid supplements on the human intestinal microbiota

    Objective; Omega-3 polyunsaturated fatty acids (PUFAs) have anticolorectal cancer (CRC) activity. The intestinal microbiota has been implicated in colorectal carcinogenesis. Dietary omega-3 PUFAs alter the mouse intestinal microbiome compatible with antineoplastic activity. Therefore, we investigated the effect of omega-3 PUFA supplements on the faecal microbiome in middle-aged, healthy volunteers (n=22). Design A randomised, open-label, cross-over trial of 8 weeks’ treatment with 4 g mixed eicosapentaenoic acid/docosahexaenoic acid in two formulations (soft-gel capsules and Smartfish drinks), separated by a 12-week ‘washout’ period. Faecal samples were collected at five time-points for microbiome analysis by 16S ribosomal RNA PCR and Illumina MiSeq sequencing. Red blood cell (RBC) fatty acid analysis was performed by liquid chromatography tandem mass spectrometry. Results; Both omega-3 PUFA formulations induced similar changes in RBC fatty acid content, except that drinks were associated with a larger, and more prolonged, decrease in omega-6 PUFA arachidonic acid than the capsule intervention (p=0.02). There were no significant changes in α or β diversity, or phyla composition, associated with omega-3 PUFA supplementation. However, a reversible increased abundance of several genera, including Bifidobacterium, Roseburia and Lactobacillus was observed with one or both omega-3 PUFA interventions. Microbiome changes did not correlate with RBC omega-3 PUFA incorporation or development of omega-3 PUFA-induced diarrhoea. There were no treatment order effects. Conclusion; Omega-3 PUFA supplementation induces a reversible increase in several short-chain fatty acid-producing bacteria, independently of the method of administration. There is no simple relationship between the intestinal microbiome and systemic omega-3 PUFA exposure. Trial registration number; ISRCTN18662143

    The Primary PE and School Sport Premium

    Get PDF
    Central to London’s successful bid to host the 2012 Olympic and Paralympic Games, was the Government’s commitment to improve competitive sport and the sporting habits of young people (Ofsted, 2014). On the 12th March 2013, the then Prime Minister, David Cameron, announced that Primary Schools in England would receive funding worth £150 million per year to create a sustainable infrastructure for long-lasting change and improve the provision of physical education (PE) and sport across all state maintained primary schools. Speaking at the time, he said: ‘We can create a culture in our schools that encourages all children to be active and enjoy sport.’ He added: ‘The Olympic and Paralympic Games marked an incredible year for this country and I will always be proud that we showed the world what Britain can do. I want to ensure the Games count for the future too and that means capitalising on the inspiration young people took from what they saw during those summer months.’: https://www.bbc.co.uk/sport/21808982 Six years on, and with a total investment now of over £1.2 billion, the Primary PE and Sport Premium (here onwards referred to as the PESS Premium) has been a defining feature of the London 2012 legacy. Invariably funding streams at this level do not last forever or in the same format, which raises significant questions about what impact the funding has had on young people since 2013. We believe that a significant investment from Government merits debate and accountability at the highest possible level and that it should acknowledge where the opportunities and shortcomings of such a policy have left us. During the years of austerity, mounting concerns have arisen over the present and long term state of children’s health and the need for the debate to be heard is now imperative. To date there has been little critical appraisal of the PESS Premium funding. This report aims to begin a necessary process and in doing so, brings together evidence from across the sector to consider the future of the PESS Premium post 2018. During the course of the report, we outline and underpin the holistic value and importance of PE for every child. We examine the historic status and funding of PE and Sport and the nature and increasing diversity of the workforce. How has the PESS Premium funding impacted the way in which the subject is regarded and the ability of those tasked with delivering it to discharge their responsibilities? We have uncovered an abiding uncertainty about the nature of the PESS Premium itself; the ways in which it may be spent and its effect on an increasing divide between PE specialists, generalists and externally contracted coaches. Will its legacy be to have established a secure foundation for lifelong physical activity, sport and education – or is it, in effect, another temporarily seductive mirage, leaving PE precisely where it has become accustomed to be; regularly sidelined, delivered largely by those who are not qualified teachers and perpetuating the status quo for the children who already belong to groups that are perceived to be at a disadvantage? The PESS Premium funding is a significant sum and these questions deserve answers. This report is therefore our contribution to an essential debate, containing practical suggestions that we hope will be of use to policy makers. We invite all who care about the physical and mental health and emotional wellbeing of children to join the discussion
