Redistributive land reforms, agricultural productivity, and structural change: New cross‐national evidence

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Large‐scale land reforms constitute a substantial redistribution of wealth and reallocation of agricultural land, which is a major form of asset and production input in developing countries. While land redistribution (from the rich to the poor) remains a highly controversial issue, extensive evidence on its effect is limited.

When Does Alzheimer's Disease Start? Plasma Aβ42/40 Assays Show Steep Changes at Aβ‐PET Centiloid 15, Mean Age of 66 Years

open access: yesAnnals of Neurology, EarlyView.
Objective Sporadic late‐onset Alzheimer's disease (AD) is characterized by a long pre‐clinical phase where amyloid‐beta (Aβ) and tau begin to accumulate in the brain. The primary objective was to determine the age at which AD starts by finding the average population age when both positron emission tomography (PET) Aβ (Aβ‐PET) and plasma Aβ42/40 become ...

The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological
