    Seeing the invisible: from imagined to virtual urban landscapes

    Urban ecosystems consist of infrastructure features working together to provide services for inhabitants. Infrastructure functions akin to an ecosystem, having dynamic relationships and interdependencies. However, with age, urban infrastructure can deteriorate and stop functioning. Additional pressures on infrastructure include urbanizing populations and a changing climate that exposes vulnerabilities. To manage the urban infrastructure ecosystem in a modernizing world, urban planners need to integrate a coordinated management plan for these co-located and dependent infrastructure features. To implement such a management practice, an improved method for communicating how these infrastructure features interact is needed. This study aims to define urban infrastructure as a system, identify the systematic barriers preventing implementation of a more coordinated management model, and develop a virtual reality tool to provide visualization of the spatial system dynamics of urban infrastructure. Data was collected from a stakeholder workshop that highlighted a lack of appreciation for the system dynamics of urban infrastructure. An urban ecology VR model was created to highlight the interconnectedness of infrastructure features. VR proved to be useful for communicating spatial information to urban stakeholders about the complexities of infrastructure ecology and the interactions between infrastructure features.https://doi.org/10.1016/j.cities.2019.102559Published versio

    Augmenting citation chain aggregation with article maps

    Presentation slides available at: https://www.gesis.org/fileadmin/upload/kmir2014/paper4_slides.pdfThis paper presents Voyster, an experimental system that combines citation chain aggregation (CCA) and spatial-semantic maps to support citation search. CCA uses a three-list view to represent the citation network surrounding a ‘pearl’ of known relevant articles, whereby cited and citing articles are ranked according to number of pearl relations. As the pearl grows, this overlap score provides an effective proxy for relevance. However, when the pearl is small or multi-faceted overlap ranking provides poor discrimination. To address this problem we augment the lists with a visual map, wherein articles are organized according to their content similarity. We demonstrate how the article map can help the user to make relevant choices during the early stages of the search pro-cess and also provide useful insights into the thematic structure of the local citation network

    Trust in ICT-Based New Product Development - Guidelines for Virtual New Product Development Teams

    Get PDF
    The traditional process of new product development is focusing on an intra-organizational workflow, which should - in its ideal form - be done by virtual interdisciplinary teams. Team members should be from several departments like manufacturing, research & development, sales and marketing. But innovation is happening more and more in networks of companies, clusters or so called network companies. The following article delivers a framework of guidelines for virtual team management in order to improve the success of innovation strategies.e-collaboration, virtual team work, new product development, Research and Development/Tech Change/Emerging Technologies,

    A sequential analysis of procedural meeting communication: How teams facilitate their meetings

    Get PDF
    How do teams facilitate their own meetings? Unmanaged (or free) social interaction often leads to poor decision-making, unnecessary conformity, social loafing, and ineffective communication processes, practices, and products. The purpose of this paper is to investigate the potential benefits of procedural communication in team meetings. The role of procedural communication, defined as verbal behaviors that structure group discussion to facilitate goal accomplishment, was examined in 59 team meetings from 19 organizations. Meeting behaviors were videotaped and coded. Lag sequential analysis revealed that procedural meeting behaviors are sustained by supporting statements within the team interaction process. They promote proactive communication (e.g., who will do what and when) and significantly inhibit dysfunctional meeting behaviors (e.g., losing the train of thought, criticizing others, and complaining). These patterns were found both at lag1 and lag2. Furthermore, the more evenly distributed procedural meeting behaviors were across team members, the more team members were satisfied with their discussion processes and outcomes. Theoretical and practical implications are discussed

    Using data analytics for collaboration patterns in distributed software team simulations: the role of dashboards in visualizing global software development patterns

    Get PDF
    This paper discusses how previous work on global software development learning teams is extended with the introduction of data analytics. The work is based on several years of studying student teams working in distributed software team simulations. The scope of this paper is twofold. First it demonstrates how data analytics can be used for the analysis of collaboration between members of distributed software teams. Second it describes the development of a dashboard to be used for the visualization of various types of information in relation to Global Software Development (GSD). Due to the nature of this work, and the need for continuous pilot studies, simulations of distributed software teams have been created with the participation of learners from a number of institutions. This paper discusses two pilot studies with the participation of six institutions from two different countries

    A Microservice Infrastructure for Distributed Communities of Practice

    Get PDF
    Non-formal learning in Communities of Practice (CoPs) makes up a significant portion of today’s knowledge gain. However, only little technological support is tailored specifically towards CoPs and their particular strengths and challenges. Even worse, CoPs often do not possess the resources to host or even develop a software ecosystem to support their activities. In this paper, we describe a distributed, microservice-based Web infrastructure for non-formal learning in CoPs. It mitigates the need for central infrastructures, coordination or facilitation and takes into account the constant change of these communities. As a real use case, we implement an inquiry-based learning application on-top of our infrastructure. Our evaluation results indicate the usefulness of this learning application, which shows promise for future work in the domain of community-hosted, microservice-based Web infrastructures for learning outside of formal settings
