  • Per-appliance energy feedback as a moving target
  • 2019
  • Ingår i: Proceedings of the 6th International Conference on ICT for Sustainability. - CEUR-WS.
  • Konferensbidrag (refereegranskat)abstract
    • Energy feedback through interactive technologies is often proposed as a major approach to reduce household energy consumption and carbon footprint. However, this vision is challenged by critics. This paper seeks to inform this debate through a case study of an advanced energy feedback device providing runtime and de-aggregated per-appliance feedback through a smartphone app. This study, based on 15 contextual interviews, aims to investigate how users understand and act on the various levels of feedback received from the device and the resulting impact on user behaviour. We found that appliance detection can be a “moving target” that hampers the intended aims of energy feedback, as it reduces user understanding of the technology. The lack of understanding was further deepened by unrelated supplementary functionality added in the package, in the form of smart plugs. Despite gaining a better understanding of their energy consumption, the users felt limited in terms of their ability to change their behaviour considerably.

  • Gaze Behaviour on Interacted Objects during Hand Interaction in Virtual Reality for Eye Tracking Re-calibration
  • 2019
  • Ingår i: Eye Tracking Research and Applications Symposium (ETRA). - Association for Computing Machinery (ACM). - 9781450367097
  • Konferensbidrag (refereegranskat)abstract
    • In this paper, we investigate the probability and timing of attaining gaze fxations on interacted objects during hand interaction in virtual reality, with the main purpose for implicit and continuous eye tracking re-calibration. We conducted an evaluation with 15 participants in which their gaze was recorded while interacting with virtual objects. The data was analysed to fnd factors infuenc-ing the probability of fxations at diferent phases of interaction for diferent object types. The results indicate that 1) interacting with stationary objects may be favourable in attaining fxations to moving objects, 2) prolonged and precision-demanding interactions positively infuences the probability to attain fxations, 3) performing multiple interactions simultaneously can negatively impact the probability of fxations, and 4) feedback can initiate and end fxations on objects.

  • Engaging Successful Migrant Entrepreneurs in Socially Responsible Causes : A Case from Sweden
  • 2019
  • Ingår i: Responsible People : The Role of the Individual in CSR, Entrepreneurship and Management Education. - Cham : Palgrave Macmillan. - 978-3-030-10739-0 - 978-3-030-10740-6 ; s. 15-38
  • Bokkapitel (övrigt vetenskapligt)abstract
    • A wide range of policy and practical initiatives aimed at improving the engagement and performance in CSR in SMEs have been initiated at all levels of society. A central issue is to what extent and how SMEs may be engaged in CSR initiatives. This chapter discusses CSR in Swedish SMEs, more specifically how successful migrant entrepreneurs (SUME) can be engaged in initiatives facilitating the labor market integration of new migrants. The CSR perceptions, motives, and priorities of SUME in participating in initiatives that address broader social issues are explored.

  • Konferensbidrag (refereegranskat)abstract
    • How do we humanize digital interactive technology? One way is through our experience with technology. With S T R A T I C we present several post-digital concepts to discuss the relationship of the digital in regard to our human lives. We emphasize the synesthetic experience along with other aesthetic experiences and materiality issues with manifestations of the digital in the physical world, tangible approaches to sonic performances, or exposure of internal logics of technological processes. In this paper, we propose both exhibiting our work as an art installation and via a live performance. We regard it as being highly relevant to the topic of the TEI Arts Track exhibition: post-digital materiality at the intersection of the analog and the digital, and to its tangible aspects.

  • Climate change effects of forestry and substitution of carbon-intensive materials and fossil fuels
  • 2017

  • Tidskriftsartikel (refereegranskat)abstract
    • We estimate the climate effects of directing forest management in Sweden towards increased carbon storage in forests with more land set-aside for protection, or towards increased forest production for the substitution of carbon-intensive materials and fossil fuels, relative to a reference case of current forest management. We develop various scenarios of forest management and biomass use to estimate the carbon balances of the forest systems, including ecological and technological components, and their impacts on the climate in terms of radiative forcing. The scenario with increased set-aside area and the current level of forest residue harvest resulted in lower cumulative carbon emissions compared to the reference case for the first 90 years, but then showed higher emissions as reduced forest harvest led to higher carbon emissions from energy and material systems. For the reference case of current forest management, increased harvest of forest residues gave increased climate benefits. The most climatically beneficial alternative, expressed as reduced cumulative radiative forcing, in both the short and long terms is a strategy aimed at high forest production, high residue recovery rate, and high efficiency utilization of harvested biomass. Active forest management with high harvest levels and efficient forest product utilization will provide more climate benefit, compared to reducing harvest and storing more carbon in the forest.

  • Developing a framework for evaluating the sustainability of computing projects
  • 2017
  • Ingår i: LIMITS 2017 - Proceedings of the 2017 Workshop on Computing Within Limits. - Association for Computing Machinery, Inc. - 9781450349505 ; s. 111-117

    • Toyama [19] has proposed a "preliminary taxonomy" for classifying computing projects as a way of separating sustainable computing efforts from unsustainable ones. In this paper we explore the feasibility of Toyama's taxonomy. We begin by describing how we revised and developed his taxonomy to make it more practically useful and then conducted a pilot study where we used the revised version to evaluate four computing projects. The pilot study was then used as a foundation for further discussing and developing the revised taxonomy into yet another, third and final version which we have chosen to call the Sustainable Computing Evaluation Framework (SCEF). While our proposed framework (SCEF) is more practically useful than Toyama's "preliminary taxonomy", there are still challenges that need to be addressed and we end the paper by suggesting where future efforts could be focused.

  • Evaluating citizen science data for forecasting species responses to national forest management
  • 2017
  • Ingår i: Ecology and evolution. - 2045-7758. ; 7:1, s. 368-378
  • Tidskriftsartikel (refereegranskat)abstract
    • The extensive spatial and temporal coverage of many citizen science datasets (CSD) makes them appealing for use in species distribution modeling and forecasting. However, a frequent limitation is the inability to validate results. Here, we aim to assess the reliability of CSD for forecasting species occurrence in response to national forest management projections (representing 160,366km2) by comparison against forecasts from a model based on systematically collected colonization-extinction data. We fitted species distribution models using citizen science observations of an old-forest indicator fungus Phellinus ferrugineofuscus. We applied five modeling approaches (generalized linear model, Poisson process model, Bayesian occupancy model, and two MaxEnt models). Models were used to forecast changes in occurrence in response to national forest management for 2020-2110. Forecasts of species occurrence from models based on CSD were congruent with forecasts made using the colonization-extinction model based on systematically collected data, although different modeling methods indicated different levels of change. All models projected increased occurrence in set-aside forest from 2020 to 2110: the projected increase varied between 125% and 195% among models based on CSD, in comparison with an increase of 129% according to the colonization-extinction model. All but one model based on CSD projected a decline in production forest, which varied between 11% and 49%, compared to a decline of 41% using the colonization-extinction model. All models thus highlighted the importance of protected old forest for P.ferrugineofuscus persistence. We conclude that models based on CSD can reproduce forecasts from models based on systematically collected colonization-extinction data and so lead to the same forest management conclusions. Our results show that the use of a suite of models allows CSD to be reliably applied to land management and conservation decision making, demonstrating that widely available CSD can be a valuable forecasting resource.
