steel research international, EarlyView.High Nb (2.4 wt.%) addition to Maraging 300 steel drives lattice distortion and nanoscale Nb–Mo‐rich precipitation, confirmed by energy‐dispersive X‐ray spectroscopy mapping (Mo ~5.4 wt.%, Nb ~2.5 wt.%). Nanoindentation reveals strong matrix hardening (H >4.8 GPa) at 480°C aging, while 560°C induces ~1.92 vol.% reverted austenite, enabling tunable ...

International Journal of Urban and Regional Research, EarlyView.Abstract This article engages signage as a medium through which urban stakeholders negotiate the politics of housing redevelopment and gentrification in cities. Focusing on Toronto, we examine housing‐related signage in three neighbourhoods where social mix approaches to redevelopment have ushered in gentrification: Parkdale, Regent Park, and Moss Park.

Is the rent too high? Land ownership and monopoly power
Real Estate Economics, EarlyView.Abstract Pricing power in real estate markets can reduce housing supply and redevelopment relative to the social optimum. We show how pricing power interacts with popular redevelopment subsidies and zoning regulations. Using building‐level rental income data from NYC, we find that increased concentration is correlated with increased rents.
