    Despite the large number and variety of tools and services available today for exploring scholarly data, current support is still very limited in the context of sensemaking tasks, which go beyond standard search and ranking of authors and publications, and focus instead on i) understanding the dynamics of research areas, ii) relating authors ‘semantically’ (e.g., in terms of common interests or shared academic trajectories), or iii) performing fine-grained academic expert search along multiple dimensions. To address this gap we have developed a novel tool, Rexplore, which integrates statistical analysis, semantic technologies, and visual analytics to provide effective support for exploring and making sense of scholarly data. Here, we describe the main innovative elements of the tool and we present the results from a task-centric empirical evaluation, which shows that Rexplore is highly effective at providing support for the aforementioned sensemaking tasks. In addition, these results are robust both with respect to the background of the users (i.e., expert analysts vs. ‘ordinary’ users) and also with respect to whether the tasks are selected by the evaluators or proposed by the users themselves

    An Analytic Approach to Understanding Process Dynamics in Geodesign Studies

    Recent advances in planning support technologies has enabled interactive collaboration in design processes by multiple stakeholder groups. The available technologies collect and store information on both the evolution of design alternatives and the interactions of participants involved in the design process. However, making sense of available process log-data is still a challenge. This study focuses on process analytics in geodesign studies, where iterative collaboration between stakeholders generates design alternatives and consensus by negotiation. Early findings demonstrate how geodesign process analytics makes it possible to gain insights both in recurrent patterns in participant behavior and in the evolution of the design. The approach, based on the enhanced adaptive structuration theory framework, has been tested using data collected by the Geodesignhub web-based collaborative planning support systems in the Cagliari (Italy) geodesign study

    Collaborative Innovation in Healthcare: Boundary Resources for Peripheral Actors

    Get PDF
    Realizing the potential of digital technologies in hospital care requires collaborative innovation among multiple actors both within and beyond hospitals. Our research investigates the question: what does it take to foster collaborative innovation within a traditionally siloed and closed health information infrastructure? Empirical findings are derived from three cases, which we analyze by focusing on how innovation relates to interfaces with hospitals’ information infrastructures. We draw on literature on digital platforms and innovation ecosystems and focus on the notion of boundary resources to characterize these innovation interfaces. While this notion has mainly addressed the concerns of platform owners for ‘securing’ and ‘resourcing’ their platforms, our analysis also points to resources related to peripheral actors’ needs, specifically ‘discovering’ and ‘vesting’ resources. Discovering resources assist innovators in making sense of possibilities and limitations, while vesting resources relate to value appropriation. These resources are crucial for collaborative innovation in existing hospital information infrastructures

    Biopolitics multiple: migration, extraction, subtraction

    Get PDF
    This article proposes ‘biopolitics multiple’ as an approach to the heterogeneity of biopolitical technologies deployed to govern migration today. Building on work that has started to develop analytical vocabularies to diagnose biopolitical technologies that work neither by fostering life nor by making people die in a necropolitical sense, it conceptualises ‘extraction’ and ‘subtraction’ as two such technologies that take ‘hold’ of migrants’ lives today. Extraction, explored in the paper through a focus on borderzones in Greece, captures the imbrication of biopolitics and value through the ‘outside’ creation of the economic conditions of data circulation. Subtraction, which is analysed in this article through a focus on Calais, captures the practices of (partial) non-governing by taking material and legal terrain away from migrants and reconfiguring convoluted geographies of (forced) hyper-mobility. This move allows us to understand the governmentality of migration beyond binary oppositions such as ‘making live/letting die’, biopolitics/necropolitics and inclusion/exclusion

    Decomposition-Based Decision Making for Aerospace Vehicle Design

    Get PDF
    Most practical engineering systems design problems have multiple and conflicting objectives. Furthermore, the satisfactory attainment level for each objective ( requirement ) is likely uncertain early in the design process. Systems with long design cycle times will exhibit more of this uncertainty throughout the design process. This is further complicated if the system is expected to perform for a relatively long period of time, as now it will need to grow as new requirements are identified and new technologies are introduced. These points identify a need for a systems design technique that enables decision making amongst multiple objectives in the presence of uncertainty. Traditional design techniques deal with a single objective or a small number of objectives that are often aggregates of the overarching goals sought through the generation of a new system. Other requirements, although uncertain, are viewed as static constraints to this single or multiple objective optimization problem. With either of these formulations, enabling tradeoffs between the requirements, objectives, or combinations thereof is a slow, serial process that becomes increasingly complex as more criteria are added. This research proposal outlines a technique that attempts to address these and other idiosyncrasies associated with modern aerospace systems design. The proposed formulation first recasts systems design into a multiple criteria decision making problem. The now multiple objectives are decomposed to discover the critical characteristics of the objective space. Tradeoffs between the objectives are considered amongst these critical characteristics by comparison to a probabilistic ideal tradeoff solution. The proposed formulation represents a radical departure from traditional methods. A pitfall of this technique is in the validation of the solution: in a multi-objective sense, how can a decision maker justify a choice between non-dominated alternatives? A series of examples help the reader to observe how this technique can be applied to aerospace systems design and compare the results of this so-called Decomposition-Based Decision Making to more traditional design approaches

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

    Get PDF
    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

    From Citizen Sensing to Collective Monitoring: Working through the Perceptive and Affective Problematics of Environmental Pollution

    Get PDF
    Citizen sensing, or the practice of monitoring environments through low-cost and do-it-yourself (DIY) digital technologies, is often structured as an individual pursuit. The very term citizen within citizen sensing suggests that the practice of sensing is the terrain of one political subject using a digital device to monitor her or his environment to take individual action. Yet in some circumstances, citizen sensing practices are reworking the sites and distributions of environmental monitoring toward other configurations that are more multiple and collective. What are the qualities and capacities of these collective modes of sensing, and how might they shift the assumed parameters—and effectiveness—of citizen sensing? We engage with Simondon’s writing to consider how a “perceptive problematic” generates collectives for feeling and responding to events (or an “affective problematic”), here through the ongoing event of air pollution. Further drawing on writing from Stengers, we discuss how the “work” of citizen sensing involves much more than developing new technologies, and instead points to the ways in which new practices, subjects, milieus, evidence, and politics are worked through as perceptive and affective commitments to making sense of and addressing the problem of pollution.The research leading to these results has received funding from the European Research Council under the European Union’s Seventh Framework Programme (FP/2007–2013)/ERC Grant Agreement No. 313347
