The battle of Detroit and anti-communism in the depression era

This article is an exploration of Diego Rivera's visit to Detroit in 1932-3. It seeks to use his experiences, and in particular the spectacular popular reaction to the Detroit Industry murals he pointed, as a prism for anaylsing varieties of anti-communism in. Detroit in the depression era. The article argues that close relationships between Private capitalists, most notably Hen?)) Ford and a Mexican communist, expose contradictions in big business's use of anti-communism in the interwar period, and suggest that anti-communism was a more complicated phenomenon than simply a tool for the promotion of free enterprise'. Moreover, by comparing the public reaction to the artists' work with their original intent, it is possible to see how members of Detroit's society unconsciously, used anti-communism to sublimate broader concerns over race and ethnicity gender, politics, and religiosity in a region in the throes of profound social change. The article seeks to highlight elements of these latent anxieties and fears in order to show how anti-communism acted as a vessel for social debate

Passing the Torch? Anglo-American Encounters in the British West Indies and Negotiating White Supremacy, c. 1865–1914

This article explores encounters between U.S. tourists and British imperial actors in the British West Indies in the late nineteenth and early twentieth century. Drawing on published traveller accounts from the period, it argues that literary cross-fertilization and practices of colonial sociability encouraged shared understandings of the Caribbean framed around visions of global white supremacy. Although these supported the Anglo-Saxonist project that underpinned the geopolitical rapprochement between the two powers between the 1890s and First World War, there were also tensions and disagreements, especially over which nation was best placed to defend the racial order in the Caribbean in the new century. As the volume of U.S. tourists grew, these disagreements became clearer, as revealed in the accounts given of the aftermath of the diplomatic crisis that followed the Kingston earthquake of 1907. Traveller accounts on the ground contrasted with efforts in Washington and London to resolve the crisis amicably. In this sense, the cultural politics of inter-imperial sociability did not always perfectly align with geopolitical imperatives

Economic Evaluation of Positron Emission Tomography (PET) in Non Small Cell Lung Cancer (NSCLC), CHERE Working Paper 2007/6

Background: There are several perceived benefits from introducing positron emission tomography (PET) scanning into the staging of non small lung cancer (NSCLC). However, its greatest primary benefit is the role it can potential perform in reducing the number of unnecessary diagnostic examinations and futile surgeries. Objectives: To evaluate the economic impact and cost effectiveness of PET scanning in the management of potentially operable NSCLC patients using a cost-utility model. Methods: A literature review was conducted to find relevant studies and appropriate parameters to construct a decision model. Two strategies were compared. The first strategy was a conventional work up (CWU) consisting of an x-ray, a chest computer tomography (CT) scan and brochoscopy; the second strategy consisted of a CWU plus a whole body PET scan. These two strategies were applied to two sub-groups of NSCLC patients; those that had received a positive result on their CT scan and those that got a negative result on their CT scan. The cost-effectiveness of each strategy was dependent on a number of variables that were taken from a literature review. Costs were based on the Australian diagnostic related groups, a cost calculation for a chemotherapy course and values obtained from the literature. The life expectancy and utility scores were also taken from the literature and combined to create an incremental quality adjusted life year (QALY) value for PET for each of the patient groups. Results: The mean costs in CT negative and CT positive patients were lower in the CWU strategy, costing $A 20,427 and$A 23,578 per patient respectively compared to the PET strategy ($A 20,826 and$A 24,083 per patient respectively). The mean QALYs for both the CT positive and CT negative patients were higher in PET with 2.91 and 2.11 respectively compared to the CWU of 2.88 and 2.09. The incremental cost effectiveness ratio (ICER) for the CT negative strategy was $A 14,581 and$A 52,039 for the CT positive strategy. Conclusion: The PET strategy in CT negative and CT positive patients appears to be cost effective, however, there is much uncertainty surrounding this base result, particularly in CT positive patients.PET, non-small-cell lung cancer, economic evaluation

The ICTD Government Revenue Dataset

tax; revenue; government revenue; data.A major obstacle to cross-country research on the role of revenue and taxation in development has been the weakness of available data. This paper presents a new Government Revenue Dataset (GRD), developed through the International Centre for Tax and Development (ICTD). The dataset meticulously combines data from several major international databases, as well as drawing on data compiled from all available International Monetary Fund (IMF) Article IV reports. It achieves marked improvements in data coverage and accuracy, including a standardised approach to revenue from natural resources, and holds the promise of significant improvement in the credibility and robustness of research in this area. This paper sets out the issues with existing sources and explains the process of creating the new dataset, including a discussion of remaining limitations. It then presents data on tax and revenue trends over the past two decades, while a concluding section briefly considers potential strategies for, and barriers to, more effective data collection in future.DfID, NORA

Tractography in the presence of multiple sclerosis lesions

Accurate anatomical localisation of specific white matter tracts and the quantification of their tract-specific microstructural damage in conditions such as multiple sclerosis (MS) can contribute to a better understanding of symptomatology, disease evolution and intervention effects. Diffusion MRI-based tractography is being used increasingly to segment white matter tracts as regions-of-interest for subsequent quantitative analysis. Since MS lesions can interrupt the tractography algorithm’s tract reconstruction, clinical studies frequently resort to atlas-based approaches, which are convenient but ignorant to individual variability in tract size and shape. Here, we revisit the problem of individual tractography in MS, comparing tractography algorithms using: (i) The diffusion tensor framework; (ii) constrained spherical deconvolution (CSD); and (iii) damped Richardson-Lucy (dRL) deconvolution. Firstly, using simulated and in vivo data from 29 MS patients and 19 healthy controls, we show that the three tracking algorithms respond differentially to MS pathology. While the tensor-based approach is unable to deal with crossing fibres, CSD produces spurious streamlines, in particular in tissue with high fibre loss and low diffusion anisotropy. With dRL, streamlines are increasingly interrupted in pathological tissue. Secondly, we demonstrate that despite the effects of lesions on the fibre orientation reconstruction algorithms, fibre tracking algorithms are still able to segment tracts that pass through areas with a high prevalence of lesions. Combining dRL-based tractography with an automated tract segmentation tool on data from 131 MS patients, the cortico-spinal tracts and arcuate fasciculi could be reconstructed in more than 90% of individuals. Comparing tract-specific microstructural parameters (fractional anisotropy, radial diffusivity and magnetisation transfer ratio) in individually segmented tracts to those from a tract probability map, we show that there is no systematic disease-related bias in the individually reconstructed tracts, suggesting that lesions and otherwise damaged parts are not systematically omitted during tractography. Thirdly, we demonstrate modest anatomical correspondence between the individual and tract probability-based approach, with a spatial overlap between 35 and 55%. Correlations between tract-averaged microstructural parameters in individually segmented tracts and the probability-map approach ranged between r=.53 ( p<.001 ) for radial diffusivity in the right cortico-spinal tract and r=.97 ( p<.001 ) for magnetisation transfer ratio in the arcuate fasciculi. Our results show that MS white matter lesions impact fibre orientation reconstructions but this does not appear to hinder the ability to anatomically reconstruct white matter tracts in MS. Individual tract segmentation in MS is feasible on a large scale and could prove a powerful tool for investigating diagnostic and prognostic markers

Etiology and Recovery of Neuromuscular Function Following Academy Soccer Training

Aim: To profile the etiology and recovery time-course of neuromuscular function in response to a mixed-content, standard training week in professional academy soccer players. We concurrently examined physical performance, cognitive function, and perceptual measures of mood and wellness states to identify a range of simple tests applied practitioners could use in the field as surrogate measures of neuromuscular function. Methods: Sixteen professional academy soccer players completed a range of neuromuscular, physical, perceptual, mood, and cognitive function tests at baseline and after a strenuous training day (pitch and gym), with retest at 24, 48, and 72 h, and further pitch and gym sessions after 48 h post-baseline. Maximal voluntary contraction force (MVC) and twitch responses to electrical stimulation (femoral nerve) during isometric knee-extensor contractions and at rest were measured to assess central nervous system (voluntary activation, VA) and muscle contractile (potentiated twitch force, Qtw,pot) function. Results: Strenuous training elicited decrements in MVC force post-session (−11%, p = 0.001) that remained unresolved at 72 h (−6%, p = 0.03). Voluntary activation (motor nerve stimulation) was reduced immediately post-training only (−4%, p = 0.03). No change in muscle contractile function (Qtw,pot) was observed post-training, though was reduced at 24 h (−13%, p = 0.01), and had not fully recovered 72 h after (−9%, p = 0.03). Perceptions of wellness were impaired post-training, and recovered by 24 h (sleepiness, energy) and 48 h (fatigue, muscle soreness, readiness to train). Countermovement jump performance declined at 24 h, while RSI (Reactive Strength Index) decrements persisted at 48 h. No changes were evident in adductor squeeze, mood, or cognitive function. Conclusion: Elite youth soccer training elicits substantial decrements in neuromuscular function, which are still present 72 h post-strenuous exercise. Though central processes contribute to post-exercise neuromuscular alterations, the magnitude and prolonged presence of impairments in contractile function indicates it is the restitution of muscular function (peripheral mechanisms) that explains recovery from strenuous training in academy soccer players

Charting a course for genetic diversity in the UN Decade of Ocean Science

The health of the world's oceans is intrinsically linked to the biodiversity of the ecosystems they sustain. The importance of protecting and maintaining ocean biodiversity has been affirmed through the setting of the UN Sustainable Development Goal 14 to conserve and sustainably use the ocean for society's continuing needs. The decade beginning 2021-2030 has additionally been declared as the UN Decade of Ocean Science for Sustainable Development. This program aims to maximize the benefits of ocean science to the management, conservation, and sustainable development of the marine environment by facilitating communication and cooperation at the science-policy interface. A central principle of the program is the conservation of species and ecosystem components of biodiversity. However, a significant omission from the draft version of the Decade of Ocean Science Implementation Plan is the acknowledgment of the importance of monitoring and maintaining genetic biodiversity within species. In this paper, we emphasize the importance of genetic diversity to adaptive capacity, evolutionary potential, community function, and resilience within populations, as well as highlighting some of the major threats to genetic diversity in the marine environment from direct human impacts and the effects of global climate change. We then highlight the significance of ocean genetic diversity to a diverse range of socioeconomic factors in the marine environment, including marine industries, welfare and leisure pursuits, coastal communities, and wider society. Genetic biodiversity in the ocean, and its monitoring and maintenance, is then discussed with respect to its integral role in the successful realization of the 2030 vision for the Decade of Ocean Science. Finally, we suggest how ocean genetic diversity might be better integrated into biodiversity management practices through the continued interaction between environmental managers and scientists, as well as through key leverage points in industry requirements for Blue Capital financing and social responsibility.info:eu-repo/semantics/publishedVersio
