  • The Image Fallacy: Rethinking the Tragedy of the Commons 

    Jentoft, Svein (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-05)
    An image is what we have in our head and what we make up in an allegory, a name, a metaphor, a text, a map or in a drawing. None of these should be confused with the thing that is being imagined. They are not the real thing, just our imaginations of it. Still, we could not do without them, for instance when governing small-scale fisheries. They make us understand what we are up to and the track we ...

  • Adjusting the Fitting of Fluorescence-Based Dose-Response Kinase Inhibition Assay to Account for Fluorescent Inhibitors 

    Petit, Guillaume Axel (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-11)
    Fluorescence is routinely used to monitor kinase inhibition in commercial assays. Occasionally fluorescent compounds can interfere with the fluorescent reading. To address this issue, the problematic data are usually truncated to improve the fit, however, this approach raises ethical and reproducibility concerns. Instead, it is suggested to adjust the fitting formula, to account for the autofluorescence ...
