Augmented reality (AR) systems offer new possibilities for enhancing how people interact with information and their environment in the construction sector. However, traditional software-driven approaches to AR system design have limitations in creating intuitive user experiences. This research presents a new user-centric framework and ontology for BIM-AR system development focused on human needs and perspectives. The BIM-AR Framework consists of a 5-step circular hybrid process with the user at the center. To enable knowledge sharing, the Augmented Reality Computer-Human Interaction (ARCHI) ontology was developed using Protégé based on established design principles. Initial validation indicates the framework's potential for improved AR system design, but further expert review and case studies are needed. The ontology also requires additional refinement and linkage to open data. This pioneering research lays the groundwork for next-generation AR systems that emphasize usability by taking a human-focused approach. With rigorous validation and evolution, the framework and ontology could transform AR technology development to create more purpose-driven and adopted solutions. This research represents a paradigm shift to user-centric AR system design that has significant potential to improve how augmented reality enhances construction project management

While Building Information Modelling (BIM) can support the management and visualisation of construction projects, Augmented Reality (AR) holds great promise to enhance interaction with these complex models. The accurate positioning of BIM-AR models in construction sites is critical to ensure that the virtual and real-world environments are correctly aligned. Through a literature review, this paper presents a review of state-of-the-art positioning techniques. It explores the different techniques used to position BIM-AR models and understands the interconnections and differences between them, with an emphasis on their applicability to the construction industry. The review also explores the challenges and limitations of each technique, in terms of the trade-offs between accuracy, computational efficiency, and robustness in varying environments. By providing an overview of positioning techniques in BIM-AR, this paper aims to guide researchers and practitioners in assessing the suitability of these techniques in the context of construction sites. The insights gained from this review may inform the development of efficient BIM-AR platforms that are more aligned with the dynamic and complex nature of construction sites

Recent decades have witnessed profound shifts in the politics of medicine and the biological sciences. Members of several professions, including philosophers, lawyers and social scientists, now discuss and help regulate issues that were once left to doctors and scientists, in a form of outside involvement known as ‘bioethics’. The making of British bioethics provides the first in-depth study of the growing demand for this outside involvement in Britain, where bioethicists have become renowned and influential ‘ethics experts’. The book moves beyond existing histories, which often claim that bioethics arose in response to questions surrounding new procedures such as in vitro fertilisation. It shows instead that British bioethics emerged thanks to a dynamic interplay between changing sociopolitical concerns and the aims of specific professional groups and individuals. Highlighting this interplay has important implications for our understanding of how issues such as embryo experiments, animal research and assisted dying became high profile ‘bioethical’ concerns in late twentieth century Britain. And it also helps us appreciate how various individuals and groups intervened in and helped create the demand for bioethics, playing a major role in their transformation into ‘ethics experts’. The making of British bioethics draws on a wide range of materials, including government archives, popular sources, professional journals, and original interviews with bioethicists and politicians. It is clearly written and will appeal to historians of medicine and science, general historians, bioethicists, and anyone interested in what the emergence of bioethics means for our notions of health, illness and morality.
