    Global Assemblages, Resilience, and Earth Stewardship in the Anthropocene

    In this paper, we argue that the Anthropocene is an epoch characterized not only by the anthropogenic dominance of the Earth\u27s ecosystems but also by new forms of environmental governance and institutions. Echoing the literature in political ecology, we call these new forms of environmental governance “global assemblages”. Socioecological changes associated with global assemblages disproportionately impact poorer nations and communities along the development continuum, or the “Global South”, and others who depend on natural resources for subsistence. Although global assemblages are powerful mechanisms of socioecological change, we show how transnational networks of grassroots organizations are able to resist their negative social and environmental impacts, and thus foster socioecological resilience

    A fatigue is the accumulation of the materials damage in asphalt concrete mixtures and growing of cracks, under increasing effect of repeated vehicular loading, aging and environment factors, in this research study the effect of temperature, asphalt content, mineral filler, applied Strain, and the polymer (SBS) as a modified asphalt to evaluate their effect on fatigue crack. To achieve the objective of this research, the Nottingham flexural fatigue test is considered and superpave mix design requirements are employed. Test specimens of 380 mm length by 60 mm width and 50 mm height were sawed from slabs of the prepared mixes by rolling wheel compaction. Using Controlled-strain procedure,the tests were conducted at temperatures of 10-20-30 ±1°C and at a frequency of loading of 5 Hz. The full factor design as well, three asphalt contents 4.72, 5.22 and 5.72%, mineral filler (Portland cement, limestone dust), applied strain (400-750µs), and (2-4%) percent of (SBS) polymer, Local material properties, stress level and environmental impacts are considered for this aspect. From the result, it is observed that 2% of SBS modified mixture given a best result due to increase the percent of fatigue life to (120%) as the average when compared with the control mixture, the fatigue life has a positive relationship with asphalt content and temperature when using control strain .The fatigue life of the mixture with limestone dust have result more than mixture with Portland cement,In the general, The fatigue lifeof mixture at 400µs has given result more than 750µs

    Historical Scientific Racism and Psychiatric Publications: A Necessary International Anti-racist Code of Ethics

    Get PDF
    Ethical aspects of publishing in scientific journals are an important issue addressed since the late 1970s by the International Committee of Medical Journal Editors (1978). Today, medical journals also benefit from other international organizations’ recommendations such as the Committee on Publication Ethics, World Association of Medical Editors, and World Health Organization (WHO). These international best practices guidelines cover various ethical issues related to integrity in research, authorship, conflicts of interest, and so on

    Medicinal Plant Use and Health Sovereignty: Findings from the Tajik and Afghan Pamirs

    Get PDF
    Medicinal plants are indicators of indigenous knowledge in the context of political volatility and sociocultural and ecological change in the Pamir Mountains of Afghanistan and Tajikistan. Medicinal plants are the primary health care option in this region of Central Asia. The main objective of this paper is to demonstrate that medicinal plants contribute to health security and sovereignty in a time of instability. We illustrate the nutritional as well as medicinal significance of plants in the daily lives of villagers. Based on over a decade and half of research related to resilience and livelihood security, we present plant uses in the context of mountain communities. Villagers identified over 58 cultivated and noncultivated plants and described 310 distinct uses within 63 categories of treatment and prevention. Presence of knowledge about medicinal plants is directly connected to their use

    Opportunities for improving data sharing and FAIR data practices to advance global mental health

    Get PDF
    It is crucial to optimize global mental health research to address the high burden of mental health challenges and mental illness for individuals and societies. Data sharing and reuse have demonstrated value for advancing science and accelerating knowledge development. The FAIR (Findable, Accessible, Interoperable, and Reusable) Guiding Principles for scientific data provide a framework to improve the transparency, efficiency, and impact of research. In this review, we describe ethical and equity considerations in data sharing and reuse, delineate the FAIR principles as they apply to mental health research, and consider the current state of FAIR data practices in global mental health research, identifying challenges and opportunities. We describe noteworthy examples of collaborative efforts, often across disciplinary and national boundaries, to improve Findability and Accessibility of global mental health data, as well as efforts to create integrated data resources and tools that improve Interoperability and Reusability. Based on this review, we suggest a vision for the future of FAIR global mental health research and suggest practical steps for researchers with regard to study planning, data preservation and indexing, machine-actionable metadata, data reuse to advance science and improve equity, metrics and recognition

    Life satisfaction amongst police officers working in the area of child abuse investigation

    Get PDF
    Child abuse investigation is an area of work reported to be associated with high levels of work stress. This potentially places professionals at risk of psychological harm and may lead to lower life satisfaction than in the general population. The current study examined this issue within a large sample of Australian police officers. Specifically, 214 officers working in the area of child abuse investigation responded to a single global measure of life satisfaction (LS) known to be highly related to other measures of subjective wellbeing as well as clinical depression. The results revealed that, irrespective of the officers&rsquo; gender or degree of exposure to child abuse cases, the mean score from LS score was within the expected adult normative range. Further, the overall incidence of low LS in this sample (1.9 per cent) was not significantly different from the general population (4.3 per cent). The implications of these findings for police organisations are discussed.<br /

    The World Hip Trauma Evaluation Study 3 HEMIARTHROPLASTY EVALUATION BY MULTICENTRE INVESTIGATION - WHiTE 3: HEMI - AN ABRIDGED PROTOCOL

    Get PDF
    Approximately half of all hip fractures are displaced intracapsular fractures. The standard treatment for these fractures is either hemiarthroplasty or total hip arthroplasty. The recent National Institute for Health and Care Excellence (NICE) guidance on hip fracture management recommends the use of 'proven' cemented stem arthroplasty with an Orthopaedic Device Evaluation Panel (ODEP) rating of at least 3B (97% survival at three years). The Thompsons prosthesis is currently lacking an ODEP rating despite over 50 years of clinical use, likely due to the paucity of implant survival data. Nationally, adherence to these guidelines is varied as there is debate as to which prosthesis optimises patient outcomes.This study design is a multi-centre, multi-surgeon, parallel, two arm, standard-of-care pragmatic randomised controlled trial. It will be embedded within the WHiTE Comprehensive Cohort Study (ISRCTN63982700). The main analysis is a two-way equivalence comparison between Hemi-Thompson and Hemi-Exeter polished taper with Unitrax head. Secondary outcomes will include radiological leg length discrepancy measured as per Bidwai and Willett, mortality, re-operation rate and indication for re-operation, length of index hospital stay and revision at four months. This study will be supplemented by the NHFD (National Hip Fracture Database) dataset.Evidence on the optimum choice of prosthesis for hemiarthroplasty of the hip is lacking. National guidance is currently based on expert opinion rather than empirical evidence. The incidence of hip fracture is likely to continue to increase and providing high quality evidence on the optimumCite this article: A. L. Sims.
