Steering Digital Transformation: An Iterative Landscape Approach

open access: yesInformation Systems Journal, EarlyView.
ABSTRACT Digital transformation (DT) is in the limelight of organisations and society. However, it is challenging to steer a DT endeavour, which is also difficult to assess because of its complex nature. Instead of focusing solely on the typical end result of DT, we propose using a DT landscape approach.

Outcomes in austere trauma care: An analysis of patients transferred from scene compared to inter‐hospital transfers

open access: yesTransfusion, EarlyView.
Abstract Background Rapid access to surgical care has demonstrated a survival benefit in trauma. We sought to describe a state's trauma system with a single Level one trauma center. Study Design and Methods All available trauma encounters from 2015 to 2023 were classified as direct from scene and transfer cohorts.

Unequal access to timely care: Geographic variation in prehospital time among injured patients at risk of hemorrhagic shock

open access: yesTransfusion, EarlyView.
Abstract Background Hemorrhage remains the leading cause of preventable traumatic deaths, with many fatalities occurring before hospital arrival. Although geographic differences in prehospital time (PHT) are recognized, contemporary national estimates and their implications for resuscitation readiness are not well defined.

Fossil Hegemony and Capitalist Realism in Tropic of Orange

open access: yesFuture Humanities, Volume 4, Issue 1, May 2026.
ABSTRACT This article examines Karen Tei Yamashita's Tropic of Orange (1997) through the lens of Mark Fisher's influential concept ‘capitalist realism’. Scholars of petrofiction have pointed to a political ambivalence in the representation of fossil fuels, where a better understanding of fossil capital can overwhelm as much as galvanize.
