    Climate Change and Critical Agrarian Studies

    Full text link
    Climate change is perhaps the greatest threat to humanity today and plays out as a cruel engine of myriad forms of injustice, violence and destruction. The effects of climate change from human-made emissions of greenhouse gases are devastating and accelerating; yet are uncertain and uneven both in terms of geography and socio-economic impacts. Emerging from the dynamics of capitalism since the industrial revolution — as well as industrialisation under state-led socialism — the consequences of climate change are especially profound for the countryside and its inhabitants. The book interrogates the narratives and strategies that frame climate change and examines the institutionalised responses in agrarian settings, highlighting what exclusions and inclusions result. It explores how different people — in relation to class and other co-constituted axes of social difference such as gender, race, ethnicity, age and occupation — are affected by climate change, as well as the climate adaptation and mitigation responses being implemented in rural areas. The book in turn explores how climate change – and the responses to it - affect processes of social differentiation, trajectories of accumulation and in turn agrarian politics. Finally, the book examines what strategies are required to confront climate change, and the underlying political-economic dynamics that cause it, reflecting on what this means for agrarian struggles across the world. The 26 chapters in this volume explore how the relationship between capitalism and climate change plays out in the rural world and, in particular, the way agrarian struggles connect with the huge challenge of climate change. Through a huge variety of case studies alongside more conceptual chapters, the book makes the often-missing connection between climate change and critical agrarian studies. The book argues that making the connection between climate and agrarian justice is crucial

    Relationship Between the Policy Implementation Process and Officer Acceptance of Body-Worn Camera Programs

    There is a need to increase body-worn cameras in Ohio, but implementation obstacles include officer resistance. Agency leaders must understand potential barriers to body-worn camera adoption and implementation to prepare for and navigate them. In this study, the relationship was analyzed between the policy implementation process and officer acceptance of body-worn camera programs through the lens of organizational procedural justice theory, considering the possible covariate relationship with the technology acceptance model. The study was designed to determine if officer acceptance of body-worn cameras was influenced by officers being informed about body-worn camera implementation before it occurred, officers having an opportunity to participate in body-worn camera program design, and how officers were trained on body-worn camera policy and usage. The design of this study was quantitative and non-experimental, using SurveyMonkey with multiple choice and selection questions. Data were analyzed in IBM SPSS, using linear regression, univariate, and multivariate analysis. Results indicated the policy implementation process, particularly how the implementation was conducted and if the officer felt well-informed and trusted throughout the process, were indicators of overall program success. Deliberate policy implementation, including varying training methods, is recommended to help ensure program success. By overcoming these obstacles, body-worn cameras can be more widely implemented and help improve positive social change through police-community relations

    Pre-hospital trauma assessment and management of older patients and their association with patient outcomes: challenges and barriers

    BACKGROUND: Saudi Arabia faces an increasing prehospital healthcare burden from older people with injuries, but little is known about their characteristics and current treatment. METHODS: This was a sequential explanatory mixed-methods design, preceded by a scoping review on the prehospital geriatric trauma care. A retrospective quantitative study was conducted using registry data from older patients (≥55 years) admitted by ambulances from 01/08/2017 to 31/10/2021 at a major trauma centre in Saudi Arabia. A qualitative study was conducted using a purposive sample of Saudi paramedics and ambulance technicians from Riyadh and Makkah using online semi-structured interviews and analysed using the framework method. The quantitative and qualitative findings were integrated. RESULTS: The quantitative study recruited 452 eligible cases and found most of them were admitted with low falls (53.7%), normal physiology, and extremities injuries (53.1%). The study identified no significant predictors of in-hospital death (p>0.05 for all predictors), although statistical power was limited. The qualitative study recruited twenty participants and identified that they reported age-related challenges including physiological changes, polypharmacy, and communication difficulties. They all wanted training and guidelines to improve their knowledge. They reported struggling with communication difficulties, inaccurate adverse outcomes predictions, difficult intravenous cannulations, and cultural restrictions affecting care provision for female patients. I identified organisational barriers (e.g. lack of shared patient records and lack of guidelines) and cultural barriers (e.g. barriers to assessing women, attitudes towards older people, and attitudes towards paramedics) that influenced implementation of knowledge. This study also found that the participants' perceptions aligned with the retrospective study’s cohort, and they acknowledged the difficulty of predicting death in older trauma patients. CONCLUSION: Ambulance clinicians in Saudi Arabia want guidelines and training in managing older trauma patients but these need to take into account the characteristics of older trauma patients and the cultural barriers that I identified

    A survey on deep learning-based monocular spacecraft pose estimation: Current state, limitations and prospects

    Get PDF
    peer reviewedEstimating the pose of an uncooperative spacecraft is an important computer vision problem for enabling the deployment of automatic vision-based systems in orbit, with applications ranging from on-orbit servicing to space debris removal. Following the general trend in computer vision, more and more works have been focusing on leveraging Deep Learning (DL) methods to address this problem. However and despite promising research-stage results, major challenges preventing the use of such methods in real-life missions still stand in the way. In particular, the deployment of such computation-intensive algorithms is still under-investigated, while the performance drop when training on synthetic and testing on real images remains to mitigate. The primary goal of this survey is to describe the current DL-based methods for spacecraft pose estimation in a comprehensive manner. The secondary goal is to help define the limitations towards the effective deployment of DL-based spacecraft pose estimation solutions for reliable autonomous vision-based applications. To this end, the survey first summarises the existing algorithms according to two approaches: hybrid modular pipelines and direct end-to-end regression methods. A comparison of algorithms is presented not only in terms of pose accuracy but also with a focus on network architectures and models' sizes keeping potential deployment in mind. Then, current monocular spacecraft pose estimation datasets used to train and test these methods are discussed. The data generation methods: simulators and testbeds, the domain gap and the performance drop between synthetically generated and lab/space collected images and the potential solutions are also discussed. Finally, the paper presents open research questions and future directions in the field, drawing parallels with other computer vision applications

    Impact assessment support study for the review of the Community guidelines on State aid for railway undertakings

    In the wake of stagnant modal share of the European rail freight sector, this support study provides market information for the revision of the Guidelines on State aid for railway undertakings. It addresses four areas of interest: status of rail infrastructure; accessibility and costs pertaining to rolling stock; profitability and demand elasticity of rail freight ser- vices; and effectiveness of State support measures. A novel dataset of costs and revenues of rail freight across Europe, compiled using both publicly available data and input from extensive stakeholder consultation was built for that purpose. The findings are as follows. The inadequacy of intermodal terminals, congested rail networks, and costliness of private sidings all restrict the capacity of European rail infrastructure. Access to rolling stock is characterised by high costs and a lack of technical standardisation across Member States. We find that rail freight sectors in many countries are loss-making, with some segments being profitable. Efficient transshipment and transport of high freight volumes over long distances improves profitability of intermodal operations. The study shows that price sen- sitivity of rail freight services differs depending on the level of competition faced by road transport. The study also highlights to what extent higher thresholds for proportionate State aid and improved flexibility of schemes could be considered
