Antipode, EarlyView.Abstract The paper examines the existing relationships between universities and Frontex, investigating and problematising the intersection between the higher education sector and the violence of the European border regime. We introduce the concept of positivist dissonance to conceptualise these relationships within the wider “industrial‐military ...

Drones: Emergence of a transformative technology for island rodent eradications
Conservation Science and Practice, EarlyView.Drones have emerged as a potentially powerful tool to address an ongoing need for alternative rodent eradication solutions on remote islands. This potential has now been demonstrated in a diverse set of operations across the Pacific. In the coming decades, this novel toolset also offers the possibility to step beyond existing paradigms and imagine a ...

A Novel Approach for ∆K Estimation in the Fatigue Threshold Region Based on ΔKth and Kmax,th
Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT A novel procedure, proposed by Kujawski and Vasudevan 1, has been evaluated as an alternative to the ASTM E647 standard for determining the ∆Kth and Kmax,th thresholds. This method relies solely on the actual propagation of cracks, which occurs only when both thresholds are satisfied simultaneously. For long cracks, a more efficient estimation
