    Hidden Voices: Disabled Women's Experiences of Violence and Support Over the Life Course

    Get PDF
    Violence against women is a worldwide social and human rights problem that cuts across cultural, geographic, religious, social, and economic boundaries. It affects women in countries around the world, regardless of class, religion, disability, age, or sexual identity. International evidence shows that approximately three in five women experienced physical and/or sexual violence by an intimate partner. However, across the globe, women and girls with impairments or life-limiting illnesses are more susceptible to different forms of violence across a range of environments and by different perpetrators including professionals and family members as well as partners. However, they are likely to be seriously disadvantaged in gaining information and support to escape the abusive relationships. This article stems from the United Kingdom part of a comparative study with three other countries (Austria, Germany, and Iceland) funded by the European Commission (EC; 2013-2015). It presents preliminary findings, generated from life history interviews, about disabled women's experiences of violence and access to support (both formal and informal) over their life course and their aspirations for the prevention of violence in the future. The article includes examples of impairment-specific violence that non-disabled women do not experience. By bringing the voices of disabled women into the public domain, the article will facilitate a historically marginalized group to contribute to the debate about disability, violence, and support

    Outcomes of Medicare-age eligible NHL patients receiving RIC allogeneic transplantation: a CIBMTR analysis

    The application of allogeneic hematopoietic cell transplantation (allo-HCT) in non-Hodgkin lymphoma (NHL) patients ≥65 years in the United States is limited by lack of Medicare coverage for this indication. Using the Center for International Blood and Marrow Transplant Research (CIBMTR) database, we report allo-HCT outcomes of NHL patients aged ≥65 years (older cohort; n = 446) compared with a cohort of younger NHL patients aged 55-64 years (n = 1183). We identified 1629 NHL patients undergoing a first reduced-intensity conditioning (RIC) or nonmyeloablative conditioning allo-HCT from 2008 to 2015 in the United States. Cord blood or haploidentical transplants were excluded. The median age was 68 years (range 65-77) for the older cohort vs 60 years (range 55-64) in the younger cohort. The 4-year adjusted probabilities of nonrelapse mortality (NRM), relapse/progression (R/P), progression-free survival (PFS), and overall survival (OS) of the younger and older groups were 24% vs 30% (P = .03), 41% vs 42% (P = .82), 37% vs 31% (P = .03), and 51% vs 46% (P = .07), respectively. Using multivariate analysis, compared with the younger group, the older cohort was associated with increased NRM, but there was no difference between the 2 cohorts in terms of R/P, PFS, or OS. The most common cause of death was disease relapse in both groups. In NHL patients eligible for allo-HCT, there was no difference in OS between the 2 cohorts. Age alone should not determine allo-HCT eligibility in NHL, and Medicare should expand allo-HCT coverage to older adults

    New genetic loci link adipose and insulin biology to body fat distribution.

    Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms

    Genetic insights into resting heart rate and its role in cardiovascular disease

    Resting heart rate is associated with cardiovascular diseases and mortality in observational and Mendelian randomization studies. The aims of this study are to extend the number of resting heart rate associated genetic variants and to obtain further insights in resting heart rate biology and its clinical consequences. A genome-wide meta-analysis of 100 studies in up to 835,465 individuals reveals 493 independent genetic variants in 352 loci, including 68 genetic variants outside previously identified resting heart rate associated loci. We prioritize 670 genes and in silico annotations point to their enrichment in cardiomyocytes and provide insights in their ECG signature. Two-sample Mendelian randomization analyses indicate that higher genetically predicted resting heart rate increases risk of dilated cardiomyopathy, but decreases risk of developing atrial fibrillation, ischemic stroke, and cardio-embolic stroke. We do not find evidence for a linear or non-linear genetic association between resting heart rate and all-cause mortality in contrast to our previous Mendelian randomization study. Systematic alteration of key differences between the current and previous Mendelian randomization study indicates that the most likely cause of the discrepancy between these studies arises from false positive findings in previous one-sample MR analyses caused by weak-instrument bias at lower P-value thresholds. The results extend our understanding of resting heart rate biology and give additional insights in its role in cardiovascular disease development

    The accidental entrepreneur: The emergent and collective process of user entrepreneurship.

    ABSTRACT We develop a process model of how users, an understudied source of entrepreneurship, create, evaluate, share, and commercialize their ideas. We compare and contrast our model to the classic model of the entrepreneurial process, highlighting the emergent and collective nature of the user&apos;s entrepreneurial process. Users are often &quot;accidental&quot; entrepreneurs who happen upon an idea through their own use and then share it with others; more specifically, the development of an idea and subsequent experimentation, adaptation, and preliminary adoption often occur before that idea is formally evaluated as the basis of a commercial venture. Users also tend to engage in collective creative activity prior to firm formation -often within the social context provided by user communities -that results in the improvement of ideas. Finally, we provide detailed data on the prevalence of user entrepreneurship in the juvenile products industry.

    Community-based innovation and product development

    Thesis (Ph. D.)--Massachusetts Institute of Technology, Sloan School of Management, 2003.Includes bibliographical references (p. 209-219).Academics and practitioners have long been interested in understanding the sources and causes of innovative activity and the relationship between innovation and industrial change. Existing theory assumes innovative activity to be the domain of firms and research institutions, and commercial activity to be the domain of firms and entrepreneurially-minded individuals. Work in this tradition finds it difficult to explain the emergence of new fields and technological trajectories. This thesis suggests and provides evidence for the idea that social activity may precede and heavily influence both firm and market formation via the innovative activities that take place within user "communities." "Communities" are composed of loosely-affiliated individuals with common interests. They are characterized by a lack of formal coordination and the free flow of information. These characteristics allow for rich information and feedback and the matching of problems with individuals who possess the ideas and means to solve them. Due to the varied skills and needs of the individuals involved, user communities are well-equipped to identify and solve a wide range of design problems. The "many hands" of communities act as an innovation development and selection process operating largely independent of the visible hands of firms and the invisible hand of markets. Each essay in the thesis investigates the impact of community-based innovation and product development process on a different level. Essay 1 discusses the impact of user-innovators and their communities on firm and industry formation; Essay 2 examines the inner-workings of four formally-organized communities; Essays 3 and 4 discuss the individual-level motivations that drive community participation. Evidence is drawn from three unique data sets in the fields of commercial sports equipment and software.by Sonali K. Shah.Ph.D
