Deflection‐based assessment of residual prestress in simply‐supported bridges accounting for creep variability

Structural Concrete, EarlyView.
Abstract Several test methods have been proposed in the literature for measuring the level of residual prestress, most of them involving either semi‐ or fully destructive techniques for local measurements which could be highly sensitive to boundary conditions and execution details.

Side‐by‐side long‐term performance assessment of GFRP‐ and steel‐reinforced concrete bridge decks

Structural Concrete, EarlyView.
Abstract The corrosion‐induced deterioration of steel‐reinforced bridge decks is a service life concern, especially in cold regions, where the use of deicing chemicals is common. To address this issue, glass fiber‐reinforced polymer (GFRP) reinforcement has received growing attention, owing to the GFRP's resistance to conventional corrosion.

Intimate Spaces on the Open Road: Navigating Access, Trust, and Ethical Boundaries during Field Research with Long Haul Truck Drivers

Symbolic Interaction, EarlyView.
Despite its ubiquity, the trucking industry is not well‐understood in social scientific literature. Gathering insight into truckers' worlds is difficult due to the solitary, isolating, and unpredictable nature of the work. An understanding of truckers' work lives and work ideologies is even further limited.

Abattoir antemortem inspection protocol: Observation of unloading improves detection of transport welfare compromises in livestock

Veterinary Record, EarlyView.
Abstract Background Ensuring livestock welfare throughout the production chain, including transport, is an ethical and regulatory imperative. However, protocols to assess transport‐related welfare during routine abattoir inspections are not standardised, including antemortem (AM) inspection by an official veterinarian at UK abattoirs.
