Health Figures: An Open Source JavaScript Library for Health Data Visualization

The way we look at data has a great impact on how we can understand it, particularly when the data is related to health and wellness. Due to the increased use of self-tracking devices and the ongoing shift towards preventive medicine, better understanding of our health data is an important part of improving the general welfare of the citizens. Electronic Health Records, self-tracking devices and mobile applications provide a rich variety of data but it often becomes difficult to understand. We implemented the hFigures library inspired on the hGraph visualization with additional improvements. The purpose of the library is to provide a visual representation of the evolution of health measurements in a complete and useful manner. We researched the usefulness and usability of the library by building an application for health data visualization in a health coaching program. We performed a user evaluation with Heuristic Evaluation, Controlled User Testing and Usability Questionnaires. In the Heuristics Evaluation the average response was 6.3 out of 7 points and the Cognitive Walkthrough done by usability experts indicated no design or mismatch errors. In the CSUQ usability test the system obtained an average score of 6.13 out of 7, and in the ASQ usability test the overall satisfaction score was 6.64 out of 7. We developed hFigures, an open source library for visualizing a complete, accurate and normalized graphical representation of health data. The idea is based on the concept of the hGraph but it provides additional key features, including a comparison of multiple health measurements over time. We conducted a usability evaluation of the library as a key component of an application for health and wellness monitoring. The results indicate that the data visualization library was helpful in assisting users in understanding health data and its evolution over time.Comment: BMC Medical Informatics and Decision Making 16.1 (2016

The use of GIS in Brownfield redevelopment

In recent years, the issue of Brownfield site development - the re-use of previously used urban land - has gained a significant place in the planning agenda. However, not all Brownfield sites are derelict or contaminated land, some are significant as environmental amenities - be it part of wider ecosystem or a green area for the local population. The growing concern to include environmental aspects into the public debate have lead the Environment Agency, the Jackson Environment Institute and the Centre for Advanced Spatial Analysis to commission a short term pilot study to evaluate the contribution of a GIS for decision support and for "discussion support".In this paper, we describe how the state-of-the-art in geographic information (GI) and GI Science (GISc) can be used in a short term and limited project to achieve a practical and usable system. We are drawing on developments in information availability, as made accessible through the World Wide Web and research themes in GISc ranging from Multimedia GIS to Public Participation GIS

Modernist Urbanism in the Age of Automobility: Producing Space in the Suburbs of Toronto and Prague

Theorizing the effects of the expanding system of automobility has been an important area of inquiry in urban studies. What remains largely absent, though, are concrete investigations into the relationships between automobility and the transformations and production of urban space. Automobility is defined by its contradictions. This dissertation explores how urban planners, architects and theorists have historically responded to and attempted to resolve the contradictions of automobility. I locate these responses within the broader theoretical framework of the production of space, considering how the mode of conceiving space from the 1920s on was directly related to the car and the expanding system of automobility. Automobility as an assemblage of objects, ideologies, and institutions was central to the way architects and planners conceived of urban space: as a work of art. I argue that this conception of space circulated globally, which I show through the work of the Czechoslovak architectural avant-garde theorist Karel Teige in the 1920s and the urban theorist Humphrey Carver in post-war Canada. In this dissertation I explore automobility and the production of space by way of two post-war suburbs: Jižní město (South City) in Prague and Willowdale in Toronto. Both places were considered as solutions to problems associated with automobility and both were key nodes in the circulation of ideas on modernist urbanism. I argue that the building of South City and the rebuilding of Willowdale are the culmination of the circulation of a modernist urbanism across space and over time that attempted to respond to the forces of urbanization and automobility through planning and designing the suburb. Overcoming the contradictions of automobility will involve more than just new technologies of mobility—urban planners, architects and theorists will have to consider the production of a wholly different space for urban life. To move beyond automobility means accounting for the ways the system of automobility unevenly affects city and suburban dwellers. In an attempt to offer a critique of the city-suburb dichotomy, this dissertation argues that to go “beyond automobility” means collapsing the separations that mark both modernism and automobility
