Missouri Botanical Garden's cycad collection: A journey through time
Plant Species Biology, EarlyView.This article summarizes the history of the Missouri Botanical Garden's extensive cycad collection. Some of the specimens currently housed in the living collections date back well over 100 years. Cycads continue to face a myriad of threats in the wild, and their conservation in ex situ collections is of critical importance to assist in their survival ...

Journal of Accounting Research, EarlyView.ABSTRACT In this paper, we develop novel measures of managerial labor market classification and competition by constructing networks of compensation benchmarking peers disclosed in proxy statements. These networks represent firms’ relative positions within the managerial labor market.

Endogenous Technology Spillovers in R&D Collaboration Networks
The RAND Journal of Economics, EarlyView.ABSTRACT We introduce an R&D network formation model where firms choose both R&D efforts and collaboration partners. Neighbors in the network benefit from each other's R&D through technology spillovers, and there exists competition effects reflecting strategic substitutability in R&D.

Geometric Linearization of Ordinary Differential Equations
Symmetry, Integrability and Geometry: Methods and Applications, 2007 The linearizability of differential equations was first considered by Lie for scalar second order semi-linear ordinary differential equations. Since then there has been considerable work done on the algebraic classification of linearizable equations and ...

Methods in Ecology and Evolution, EarlyView.Abstract Distributional data are essential for understanding species and community responses to environmental and anthropogenic change. Large biodiversity databases provide key information on distributional patterns, but their temporal coverage can be limited. Facilitating access to untapped occurrence data is a pressing need. We present the Historical
