Abortion restriction laws and mobility of scientists

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary We track the enactment of targeted regulation of abortion providers (TRAP) laws in the United States and analyze 4.98 million person‐year mobility records for 535,568 biomedical scientists from 1990 to 2018. Our estimations reveal a 0.8–1.6 percentage‐point increase in scientists' relocation probability after states enacted ...

Single Cu Atom Sites on Co3O4 Activate Interfacial Oxygen for Enhanced Reactivity and Selective Gas Sensing at Low Temperature

open access: yesSmall, EarlyView.
Atomically dispersed Cu sites on Co3O4 nanoparticles establish well‐defined Cu–O–Co interfacial linkages that promote lattice oxygen activation at markedly reduced temperatures. This structural and electronic modulation yields over twenty‐fold higher low‐temperature formaldehyde sensing responses than CuO nanoparticle analogues, enabling selective and ...

Funding, Facilities, and the Face of Homelessness: Heterogeneous Impacts of Federal Grants on Sheltered and Unsheltered Counts

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT This paper examines the causal impact of federal homeless‐assistance grants on reported homelessness and shelter capacity across 370 Continuums of Care in 2019. We exploit cross‐sectional variation in pre‐1940 housing shares, used in Community Development Block Grant formula allocations, as an instrument for combined CoC and Emergency ...

Monitoring of historical structural materials with computed tomography

open access: yesStructural Concrete, EarlyView.
Abstract Computed tomography (CT) is an excellent tool to solve certain engineering problems connected to material science (such as sulfate swelling, internal degradation due to freezing, and alkali silicate swelling) and to understand specific processes (frost peeling, acid action).
