Unpacking the Influence of Policy Advice Using Citation Network Analysis

Public Administration Review, EarlyView.
ABSTRACT Public policy often builds on a large body of policy advice—produced by bureaucrats, advisory bodies, scientists, and consultants—that has accumulated over time about a specific policy problem and appropriate policy responses. Yet, how this body of policy advice develops and which pieces of advice influence subsequent policy recommendations is

Variational characterization of interior interfaces in phase transition models on convex plane domains

Electronic Journal of Differential Equations, 2003
We consider the singularly perturbed Allen-Cahn equation on a strictly convex plane domain. We show that when the perturbation parameter tends to zero there are solutions having a transition layer that tends to a straight line segment.

A matter of timing: sagebrush steppe restoration seeding outcomes altered by species responses to warmer spring temperatures and interannual weather variation

Restoration Ecology, EarlyView.
Abstract Introduction Restoration outcomes in cold desert ecosystems like sagebrush steppe are affected by weather variability, particularly during the spring, a critical time period for seedling establishment. Seedling emergence phenology is also highly variable among species in these ecosystems.

Spatial depth for data in metric spaces

Scandinavian Journal of Statistics, EarlyView.
Abstract We propose a novel measure of statistical depth, the metric spatial depth, for data residing in an arbitrary metric space. The measure assigns high (low) values for points located near (far away from) the bulk of the data distribution, allowing quantifying their centrality/outlyingness.
