Free, prior, and informed consent, local officials, and changing biodiversity governance in Hin Nam No, Laos

open access: yesConservation Biology, Volume 38, Issue 6, December 2024.
Abstract Free, prior, and informed consent (FPIC) is now a globally established norm and is a condition of equitable engagement with Indigenous peoples and local communities in biodiversity conservation. However, implementation is frequently questioned in terms of its efficacy in top‐down‐driven governance contexts.

Reduction of Algebraic Parametric Systems by Rectification of their Affine Expanded Lie Symmetries [PDF]

open access: yes, 2006
Lie group theory states that knowledge of a $m$-parameters solvable group of symmetries of a system of ordinary differential equations allows to reduce by $m$ the number of equations. We apply this principle by finding some \emph{affine derivations} that

The distribution of microlensed light curve derivatives: the relationship between stellar proper motions and transverse velocity [PDF]

open access: yes, 1999
We present a method for computing the probability distribution of microlensed light curve derivatives both in the case of a static lens with a transverse velocity, and in the case of microlensing that is produced through stellar proper motions.
