Federal systems of government present more difficulties for international treaty formation than perhaps any other form of governance. Federal constitutions that grant subnational governments virtually exclusive regulatory authority over certain subject matter may constrain national governments...

Despite numerous attempts over the past two decades—including, most recently, the Copenhagen climate discussions in late 2009—international forest and climate negotiations have failed to produce a legally binding treaty addressing global forest management activities. This failure is due in...

Farm production and natural forest extraction remain principal livelihood strategies of local people in many rural areas of the developing world. In this paper, we apply stochastic frontier analysis to evaluate farm production efficiency and simultaneous equations modelling to estimate the...

The matrices of spanning rooted forests are studied as a tool for analysing the structure of digraphs. The problems of finding the basis bicomponents and the reachability relation, measuring vertex accessibility, and ranking from preference relations / sports competitions are considered. It is...

We study the matrices of in-forests of a weighted digraph Γ and their connections with the Laplaeian matrix of Γ. The () entry of is the total weight of spanning converging forests () with arcs such that belongs to a tree rooted at . The forest matrices, , can be calculated recursively and...

To obtain a probabilistic model for a dependent variable based on some set of explanatory variables, a distributional approach is often adopted where the parameters of the distribution are linked to regressors. In many classical models this only captures the location of the distribution but over...
