    Authentic alignment : toward an Interpretative Phenomenological Analysis (IPA) informed model of the learning environment in health professions education

    Get PDF
    It is well established that the goals of education can only be achieved through the constructive alignment of instruction, learning and assessment. There is a gap in research interpreting the lived experiences of stakeholders within the UK learning environment toward understanding the real impact – authenticity – of curricular alignment. This investigation uses a critical realist framework to explore the emergent quality of authenticity as a function of alignment.This project deals broadly with alignment of anatomy pedagogy within UK undergraduate medical education. The thread of alignment is woven through four aims: 1) to understand the alignment of anatomy within the medical curriculum via the relationships of its stakeholders; 2) to explore the apparent complexity of the learning environment (LE); 3) to generate a critical evaluation of the methodology, Interpretative Phenomenological Analysis as an approach appropriate for realist research in the complex fields of medical and health professions education; 4) to propose a functional, authentic model of the learning environment.Findings indicate that the complexity and uncertainty inherent in the LE can be reflected in spatiotemporal models. Findings meet the thesis aims, suggesting: 1) the alignment of anatomy within the medical curriculum is complex and forms a multiplicity of perspectives; 2) this complexity is ripe for phenomenological exploration; 3) IPA is particularly suitable for realist research exploring complexity in HPE; 4) Authentic Alignment theory offers a spatiotemporal model of the complex HPE learning environment:the T-icosa

    Australian policy levers for obesity prevention in early childhood

    The five studies in this thesis focused on the actions undertaken and policy infrastructure provided by the Australian Federal, State and Territory Governments to prevent obesity in early childhood. The first study used the WHO Ending Childhood Obesity implementation plan to facilitate policy mapping and compare Australia’s national action to five similar countries (published paper). The second study explored the role of intergovernmentalism in achieving national food system action and policy coherence across states working on the same policy areas (published paper). The third study used policy mapping to compare states and territories and explored their eclectic approaches to obesity policy (published paper). Both studies interviewed senior officials in health departments in Australian jurisdictions to understand the barriers and enablers of prevention policy implementation. The fourth study used the New South Wales (NSW) Healthy Eating and Active Living (HEAL) Strategy 2013-2018 as a case study of cross-sectoral collaboration in Australia (paper under review). An in-depth policy mapping tool was developed to undertake iterative policy mapping. Semi-structured interviews with 25 senior public officials across 18 agencies in the NSW Government explored the factors effecting implementation of obesity prevention policies. The fifth study explored the perspectives of mothers of young children living in NSW (published paper). Survey questions were embedded into a follow-up cross-sectional survey in a large, randomised control trial – Communicating Healthy Beginnings Advice by Telephone. Mothers were asked how much they supported six different types of policy interventions by the NSW Government. These included food and physical activity environments, settings, support programs and routine measurement of children at health appointments. Potential confounders were included in the analysis to explore associations with their level of policy support

    Supporting older people’s transport and mobility needs to promote healthy ageing

    Unprecedented population ageing and rapid urbanisation combine to pose a unique challenge for policymakers– the challenge of ensuring that the greater numbers of older people are not left behind as cities dramatically evolve. As the ability of older people to move about the city and access activities in society are essential to their well-being, there is a large and untapped scope for contributions from the population health sciences to address this challenge. To date, the limited consideration of health and healthy ageing in transport policy has contributed to the high and unsustainable car dependence in Western Europe, North America, and Australia, and the resultant lack of non-driving transport options for older people. This scenario constrains older people’s mobility and well-being, as older people have diverse mobility needs and expectations which can only be met through a range of transportation options. This thesis aims to develop a coherent approach to support older people’s mobility through non-driving transport options by examining population needs and barriers and contextual influences and interventions. To address this aim, four empirical studies were conducted, each responding to one of the four objectives that logically flow from the aim. Driven by a transdisciplinary approach, various methods were used, drawing on both primary and secondary data sources and qualitative and quantitative data types. The thesis identified the specific variables intrinsic to the population to be served that must be considered in efforts to support older people’s mobility, provided evidence of the multifactorial and interactive nature of the influences on older people’s mobility, and illustrated the need for interventions to be holistic and systemic. These four studies contribute guiding principles that constitute the approach that the thesis has set out to develop. As the evidence base from which these guiding principles are developed is grounded in the population health sciences and an appreciation for transport and mobility as a social determinant of health, this thesis has also built a case for a health promotion and, specifically, a healthy public policy approach to efforts to support older people’s mobility. Finally, the thesis has delineated the stakeholders and sectors that need to be in involved in a coherent approach to support older people’s mobility and articulated how they affect each other and why their joint and coordinated contributions are necessary

    Este livro de ATAS contém os artigos apresentados às 8as Jornadas de Segurança aos Incêndios Urbanos e às 3as Jornadas de Proteção Civil (8JORNINC-3JORPROCIV), que decorreram no Porto, Portugal. Na presente edição das 8JORNINC-3JORPROCIV foram submetidos 50 trabalhos, tendo sido aceites 42. Os trabalhos foram distribuídos em 8 sessões paralelas temáticas, em adição a 2 sessões plenárias, apresentados no dia 2 de junho de 2023. O evento foi iniciado e promovido em Portugal, sob a organização do professor Doutor João Paulo Rodrigues, com as 1as Jornadas de Segurança aos Incêndios Urbanos, em 2005, na Universidade de Coimbra, bem como nos anos seguintes, as 2as Jornadas de Segurança aos Incêndios Urbanos em 2011 e as 3as Jornadas de Segurança aos Incêndios Urbanos em 2013, também na Universidade de Coimbra. As edições seguintes aconteceram em diferentes locais: as 4as Jornadas de Segurança aos Incêndios Urbanos em 2014, no Instituto Politécnico de Bragança; as 5as Jornadas de Segurança aos Incêndios Urbanos em 2016, no Laboratório Nacional de Engenharia Civil em Lisboa; as 6as Jornadas de Segurança aos Incêndios Urbanos e 1as Jornadas de Proteção Civil em 2018, na Universidade de Coimbra; e as 7as Jornadas de Segurança aos Incêndios Urbanos e 2as Jornadas de Proteção Civil, em 2021, no Instituto Politécnico de Castelo Branco. As 8JORNINC apresentam grande importância num contexto atual de vários e graves incêndios urbanos, florestais e de interface em Portugal. A pertinência do tema da segurança na prevenção e no combate a incêndios, quer pelas consequências emergentes deste tipo de acidentes, quer pela necessidade de redução das ocorrências, do número de vítimas mortais, feridos, prejuízos materiais, patrimoniais, ambientais e sociais, leva a que as Jornadas se destinem a um leque alargado de profissionais e público em geral. As 3JORPROCIV têm como objetivo promover conhecimentos nas áreas da prevenção civil, de riscos e planos de emergência. Pretendem assim, contribuir para a atualização dos conhecimentos técnicos e científicos da segurança e proteção civil, no âmbito do planeamento e prevenção perante cenários de crise e emergência. As Jornadas de Proteção Civil permitem partilhar um leque de conhecimentos multidisciplinares suscetíveis de impulsionar uma intervenção por parte de técnicos, especialistas e dos agentes da proteção civil. A visão interdisciplinar e integradora dos problemas e desafios que a proteção civil apresenta será refletida na prevenção e mitigação dos riscos inerentes a uma situação de acidente. Os trabalhos apresentados nesta edição, permitirão o avanço das 8JORNINC-3JORPROCIV, através da divulgação dos recentes desenvolvimentos e do conhecimento nos domínios da segurança ao incêndio e proteção civil. Por fim, a comissão organizadora das 8JORNINC-3JORPROCIV gostaria de agradecer: - o apoio dos patrocinadores e das instituições do Sistema Científico e Tecnológico; - a todos os autores que partilharam os seus excelentes trabalhos; - e aos elementos da Comissão Científica que auxiliaram no processo de revisão.

    Path Following and Motion Control for Articulated Frame Steering Mobile Working Machine Using ROS2

    Get PDF
    Autonomous vehicles (AVs) have been studied and researched at least since the middle of 19s century, and the interest in these vehicles has grown in the last decade. There are many vehicle types with different steering techniques. Each is designed and manufactured depending on the need to perform specific tasks (for example, transporting passengers, transporting goods, and doing heavy duties like cutting trees, digging earth, and harvesting crops). This thesis highlights the autonomous articulated frame steering (AFS) heavy-duty mobile working machines and aims to address the problems of autonomizing the AFS machine with basic autonomy requirements, which makes the machine move without the need for human direct and indirect control. The working environment (like mines, forests, and construction sites), where heavy-duty machines are used to perform some tasks, requires an expert machine operator to drive it and control its manipulator, which increases the operator’s workload. However, due to the working environment’s limited area, the machine mostly has repetitive tasks that include following the same paths; therefore, we proposed implementing a path-following control system that could be used to help the operator by reducing the work amount. The proposed path following is based on controlling the vehicle’s position and orientation to match the desired positions and orientation on a specified path where the position’s lateral error and orientation error are minimized to zero while the vehicle follows the given path. The implemented control system is divided into many subsystems; each is responsible for a specific task, and to communicate between them we used the Robot Operating System ROS2. In this thesis, we are focusing on two of these subsystems. The first subsystem, called path following that, generates linear and angular velocities needed to make the machine follow the path. The other subsystem, called motion control, is responsible for converting the linear and angular velocities to machine commands (gear, steering, gas) and controls the machine’s acceleration and steering angle. The implemented path-following control system required understanding the machine’s kinematics and modeling the steering system. The implemented system is tested first using an AFS robot in a simulation environment, then tested on a real AFS heavy-duty machine owned by Tampere university. Moreover, the tests repeated for another path following based on the modified pure pursuit technique provided by ROS2 navigation for compression and evaluation purposes
