Provisioning a Silk Road City: Herd Management Strategies at the Urban Site of Dzhankent, Kazakhstan
Archaeometry, EarlyView.ABSTRACT This study presents evidence for herd management at the early medieval city of Dzhankent in southern Kazakhstan. Located along the Northern Silk Road, Dzhankent was a key trading node linking northern and southern areas between the 9th and 10th centuries ce.

The bread of Toledo: Prices and political economy, 1535–1800
The Economic History Review, EarlyView.Abstract We study the market for common white bread in the city of Toledo through a new 266‐year‐long series of bread prices, obtained from the cash purchases and wholesale bread‐for‐wheat contracts of large institutions. Our data are strongly consistent with fragmentary evidence on retail price regulation, as well as with shorter series from other ...

Innovation and the great divergence
The Economic History Review, EarlyView.Abstract Recent historical national accounting data show that the timing of the Great Divergence hinges on the different trends in north‐west Europe and the Yangzi Delta region of China. Although north‐west Europe only pulled ahead of the Yangzi Delta after 1700, both the positive trend of GDP per capita in north‐west Europe after 1700 and the negative

Impact of Surface Cover Types and Coverage on Hydraulic Parameters of Overland Flow
Water Resources ResearchSurface cover influences the hydraulic parameters of overland flow, subsequently affecting soil erosion. Therefore, exploring the flow dynamic mechanisms under different surface cover types is crucial.

Enhancing Recharge Beneath Low‐Permeability Landscapes with Small‐Diameter Drywells: Token Creek, WI
Groundwater, EarlyView.Shallow, small‐diameter drywells provide enhanced recharge in rural landscapes, bypassing the low infiltration rates caused by low permeability surficial soils and high ET rates. One year of monitoring data show several recharge events and overall high water quality.

Constraining Subsurface Connectivity by Water‐Trace Experiment in Deep, Semi‐Arid Karst Terrain
Groundwater, EarlyView.A water‐tracer experiment in Flagstaff, Arizona detected Rhodamine WT at a municipal well 2.7 km downgradient after 11‐13 d, yielding apparent horizontal groundwater velocities of 200‐250 m/d through >300 m of fractured carbonate. Results confirm rapid subsurface connectivity and managed aquifer recharge feasibility in deep, semi‐arid karst terrain ...
