Bounds on the degree of APN polynomials The Case of x−1+g(x)x^{-1}+g(x)

We prove that functions f:\f{2^m} \to \f{2^m} of the form $f(x)=x^{-1}+g(x)$ where $g$ is any non-affine polynomial are APN on at most a finite number of fields \f{2^m}. Furthermore we prove that when the degree of $g$ is less then 7 such functions are APN only if $m \le 3$ where these functions are equivalent to $x^3$

The Socio Bosque Program for Rainforest and Paramo Conservation, Ecuador

The Socio Bosque Program is a state-funded, nation-wide program which provides financial incentive to participating forest landowners in exchange conservation of native forests and other types of native vegetation. The program's objectives include both ecosystem conservation and poverty alleviation goals on lands that belong to local and indigenous communities and individual households
