Several instances of distributive lattices on graph structures are known. This includes c-orientations (Propp), α-orientations of planar graphs (Felsner/de Mendez) planar flows (Khuller, Naor and Klein) as well as some more special instances, e.g., spanning trees of a planar graph, matchings of planar bipartite graphs and Schnyder woods. We provide a characterization of upper locally distributi...

Oscillations play a major role in a number of biological systems, from predator-prey models of ecology to circadian clocks. In this paper we focus on the question of whether oscillations exist within dual-site phosphorylation systems. Previously, Wang and Sontag showed, using monotone systems theory, that the Michaelis-Menten (MM) approximation of the distributive and sequential dual-site phosp...

Literature in organizational justice suggest that organizational fairness in decision making processes may encourage employees’ acceptance of and positive reaction to many organizational decisions including decision in human resource interventions such as performance appraisal system. This study seeks to understand how perceived fairness in the performance appraisal process affects employees’ s...

We consider unification of terms under the equational theory of two-sided distributivity D with the axioms x*(y+z) = x*y + x*z and (x+y)*z = x*z + y*z. The main result of this paper is that Dunification is decidable by giving a non-deterministic transformation algorithm. The generated unification are: an AC1-problem with linear constant restrictions and a second-order unification problem that c...

John Rawls rejects prejusticial conceptions of distributive desert on the grounds that such conceptions are immoral and impractical. Prejusticial understandings of desert claim that desert can be understood prior to and independently of justice in social institutions, and take legitimate desert claims to provide standards for evaluating social arrangements. Some philosophers have interpreted Ra...

Abstract Despite the prominence of thresholds in theories distributive justice, there is no general account what sort role played by idea a threshold within such theories. This has allowed an ongoing lack clarity and misunderstanding around views that employ thresholds. In this article, I develop concept justice. argue contains three elements, which deploy when ranking possible distributions. T...
