King and Cochrane: The technological treadmill and racial inequity in US agriculture

Applied Economic Perspectives and Policy, EarlyView.
Abstract Between 1920 and 1969, the number of Black farmers in the US decreased from 14% of all operators to 4%. Using Martin Luther King Jr.'s critique of agricultural policy and Willard Cochrane's theory of the technological treadmill, we explore how racial discrimination was linked to policies that led to structural change in US agriculture.

Enhancing the Self‐Assembly of Step‐Growth Polymers by Narrowing Their Molar Mass Distribution: A Dynamic Bond‐Mediated Approach

Angewandte Chemie, EarlyView.
The study introduces asymmetric dynamic bond‐mediated polymerization (ADBP), a method to narrow molar mass distributions in step‐growth polymers via asymmetric, reversibly‐deactivated AA'‐type electrophiles. ADBP initially forms low‐dispersity dimers/trimers, later polymerizing into polyurethanes with controlled dispersities (Đ ≤ 1.5), yielding ...

Modelling the role of agriculture for the 20th century global terrestrial carbon balance

, 2007
In order to better assess the role of agriculture within the global climate‐vegetation system, we present a model of the managed planetary land surface, Lund–Potsdam–Jena managed Land (LPJmL), which simulates biophysical and biogeochemical processes as ...

The Pentafluorophenyl Cation: A Superelectrophile and Diradical

Angewandte Chemie, EarlyView.
From radical to diradical cation. Photoionization (PI) of the thermally generated pentafluorophenyl radical yields the pentafluorophenyl cation in the gas phase. This cation is found to be a diradical with nearly degenerate open‐shell singlet and triplet ground states, and it is even more unstable than the parent phenyl cation by ∼40 kcal mol−1 ...
