Fall prevention intervention technologies: A conceptual framework and survey of the state of the art

In recent years, an ever increasing range of technology-based applications have been developed with the goal of assisting in the delivery of more effective and efficient fall prevention interventions. Whilst there have been a number of studies that have surveyed technologies for a particular sub-domain of fall prevention, there is no existing research which surveys the full spectrum of falls prevention interventions and characterises the range of technologies that have augmented this landscape. This study presents a conceptual framework and survey of the state of the art of technology-based fall prevention systems which is derived from a systematic template analysis of studies presented in contemporary research literature. The framework proposes four broad categories of fall prevention intervention system: Pre-fall prevention; Post-fall prevention; Fall injury prevention; Cross-fall prevention. Other categories include, Application type, Technology deployment platform, Information sources, Deployment environment, User interface type, and Collaborative function. After presenting the conceptual framework, a detailed survey of the state of the art is presented as a function of the proposed framework. A number of research challenges emerge as a result of surveying the research literature, which include a need for: new systems that focus on overcoming extrinsic falls risk factors; systems that support the environmental risk assessment process; systems that enable patients and practitioners to develop more collaborative relationships and engage in shared decision making during falls risk assessment and prevention activities. In response to these challenges, recommendations and future research directions are proposed to overcome each respective challenge.The Royal Society, grant Ref: RG13082

CHORUS Deliverable 2.2: Second report - identification of multi-disciplinary key issues for gap analysis toward EU multimedia search engines roadmap

After addressing the state-of-the-art during the first year of Chorus and establishing the existing landscape in multimedia search engines, we have identified and analyzed gaps within European research effort during our second year. In this period we focused on three directions, notably technological issues, user-centred issues and use-cases and socio- economic and legal aspects. These were assessed by two central studies: firstly, a concerted vision of functional breakdown of generic multimedia search engine, and secondly, a representative use-cases descriptions with the related discussion on requirement for technological challenges. Both studies have been carried out in cooperation and consultation with the community at large through EC concertation meetings (multimedia search engines cluster), several meetings with our Think-Tank, presentations in international conferences, and surveys addressed to EU projects coordinators as well as National initiatives coordinators. Based on the obtained feedback we identified two types of gaps, namely core technological gaps that involve research challenges, and “enablers”, which are not necessarily technical research challenges, but have impact on innovation progress. New socio-economic trends are presented as well as emerging legal challenges

The wire and the world: narrative and metanarrative

Rarely, if ever, has a television drama constructed a narrative with such a strong thrust to metanarrative. Its intricate and interwoven storylines dramatise the dialectical interaction of individual aspirations and institutional dynamics. These build into a story of a city, not only the story of Baltimore in its particularity, but with a metaphoric drive toward the story of Everycity. Every character and storyline pulses with symbolic resonance radiating out to a characterisation of the nature of contemporary capitalism. While the text itself does not name the system, the metatext does so with extraordinary clarity and force. David Simon, the primary voice of this collective creation, has engaged in a powerfully polemical discourse articulating the world view underlying the drama. This paper will explore that world view. It will examine how specific plots open into an analysis of the social-political-economic system shaping it all. It will moreover argue that The Wire has demonstrated the potential of television narrative to dramatise the nature of the social order, a potential that has long been neglected or inadequately pursued in the history of television drama. In probing the parameters of the intricate interactions between individuals and institutions, The Wire excavates underlying structures of power and stimulates engagement with overarching ideas.It bristles, even boils over, with systemic critique. While it offers no expectation of an alternative, it provokes reflection on the need for one and an aspiration towards one. Indeed some commentators have raised the question of whether The Wire is a marxist television drama. While David Simon has explicitly stated that he is not a marxist, the question remains. What would a marxist television drama look like? It would look very much like The Wire, this paper contends

Mixing the Digital, Social, and Cultural: Learning, Identity, and Agency in Youth Participation

Part of the Volume on Youth, Identity, and Digital MediaHow do youth use media and technology as they learn to be participants in civic and democratic practices? We share two case studies -- one from a media arts production organization and one from a school board youth group -- that revolve around youth-adult interactions in learning environments that offer youth real opportunities to be influential in their respective communities. The cases feature youth and their involvements with digital media, pedagogical approaches, and engagements that enhance their participatory capacities. There are multiple channels through which these interactions happen, some with and facilitated by adults and others created and negotiated by youth. We describe how youth and adults establish learning environments for each other, negotiate the grounds for participation, and explore the possibilities and limitations of social and digital technologies in these processes, supporting the idea that this learning is something that young people do as agents in their development

Ultra-wideband radar for simultaneous and unobtrusive monitoring of respiratory and heart rates in early childhood:A Deep Transfer Learning Approach

Unobtrusive monitoring of children’s heart rate (HR) and respiratory rate (RR) can be valuable for promoting the early detection of potential health issues, improving communication with healthcare providers and reducing unnecessary hospital visits. A promising solution for wireless vital sign monitoring is radar technology. This paper presents a novel approach for the simultaneous estimation of children’s RR and HR utilizing ultra-wideband (UWB) radar using a deep transfer learning algorithm in a cohort of 55 children. The HR and RR are calculated by processing radar signals via spectrogram from time epochs of 10 s (25 sample length of hamming window with 90% overlap) and then transforming the resultant representation into 2-dimensional images. These images were fed into a pre-trained Visual Geometry Group-16 (VGG-16) model (trained on ImageNet dataset), with weights of five added layers fine-tuned using the proposed data. The prediction on the test data achieved a mean absolute error (MAE) of 7.3 beats per minute (BPM &lt; 6.5% of average HR) and 2.63 breaths per minute (BPM &lt; 7% of average RR). We also achieved a significant Pearson’s correlation of 77% and 81% between true and extracted for HR and RR, respectively. HR and RR samples are extracted every 10 s.</p
