Beggars as Rational Choosers

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT American municipalities increasingly regulate panhandling. That regulation is controversial. The determinants of panhandling activeness are unknown, and it is doubted whether panhandling activity responds rationally to incentives. To shed light on these issues, we collect data on hundreds of panhandlers and the passersby they solicit at ...

Microstructure Characterization of Bending Effects in 304L Stainless Steel Cladded with Low‐Alloy Steel Weld

open access: yessteel research international, EarlyView.
Prebending of 304L/Q345R cladded plates significantly alters the subsequent weld thermal cycle and modifies the local interfacial microstructure. Combined electron backscatter diffraction (EBSD) and microscopy analysis demonstrates that deformation twinning, martensitic transformation, and defect initiation are concentrated at the trimaterial junction,

Influence of Oxygen Contamination on the Genesis of Nonmetallic Inclusions in a Microalloyed Steel

open access: yessteel research international, EarlyView.
Oxygen contamination during melting of steels strongly affects the evolution of nonmetallic inclusions. Controlled remelting experiments, combined with SEM/EDS analysis and thermodynamic simulations, reveal how reoxidation promotes the transformation of alumina‐based inclusions into complex FeO–MnO oxides and other interactions.

Pittman‐Robertson and Dingell‐Johnson: A Congressional endorsement of state supremacy over wildlife?

open access: yesWildlife Society Bulletin, EarlyView.
Abstract The Pittman–Robertson Act of 1937 (PR) and the Dingell–Johnson Act of 1950 (DJ) provide states with substantial capacity to manage fish and wildlife by directing revenue from federal excise taxes on hunting and fishing equipment to states. The precise scope of state and federal wildlife management authority has been a topic of debate among ...

In pursuit of just elephant management: Making a case for legal reform

open access: yesWildlife Society Bulletin, EarlyView.
Abstract Elephant management in South Africa remains entangled in legal, ethical, and ecological complexity. Despite the adoption of the 2008 Norms and Standards for Elephant Management and the 2016 Norms and Standards for the Management of Damage‐Causing Animals in South Africa, governance and management challenges persist across fenced reserves, open

Micro‐Mechanism Informed Neural Networks for Process‐Property Prediction in Laser Powder Bed Fusion

open access: yesArtificial Intelligence for Engineering, EarlyView.
Hard physics embedding, where neural networks learn residuals relative to analytical baselines, substantially outperforms soft loss‐function constraints for extrapolation in LPBF process–property prediction. Physics integration architecture determines generalization capability more than constraint quantity.

Quantitative Structure–Property Relationship for High Flash Point of Ester Oil Molecules and Its Experimental Verification

open access: yesHigh Voltage, EarlyView.
ABSTRACT With the increasing voltage of ester oil‐filled transformers and their application in offshore wind power, developing high‐performance, fire‐resistant esters is crucial for enhancing transformer safety. Flash point, a key indicator of fire‐resistant performance for esters, is directly related to the molecular structures.

The contribution of the humanities to the theory and practice of public administration in the 21st century

open access: yesAustralian Journal of Public Administration, EarlyView.
Abstract This Forum Article integrates a range of four contributions which are all underpinned by the conviction that the rediscovery of the humanities may be beneficial to the field of public administration. The first piece examines the contribution that philosophy, as a key discipline of the humanities, can provide to the field of public ...
