This article provides the history underlying the journal impact factor and weaknesses of this measure to evaluate journal quality. The Eigenfactor and Article Influence Scores are suggested as an improved way to compare research quality and impact across disciplines. The network analysis underlying the Eigenfactor approach suggests the agricultural and natural resource economics profession can have a larger impact on the scientific community by directing more research effort towards interdisciplinary work. The Article Influence approach is used to develop a seven-tier system to evaluate research quality, to be used either to guide individual faculty about where to publish their research or to evaluate the research portfolio of a department.

Prior appropriations of river flows (primarily to agriculture) have greatly reduced flow in many Oregon streams, causing major changes in stream ecosystems. This study focuses on trade-offs between instream and agricultural uses for the two largest irrigation districts in Oregon's Deschutes River basin. Both short- and long-term water lease strategies are examined, as are requirements now in place that water leases be accompanied by fallowing land formerly served by the leased water. The low-cost strategies combine canal lining with reductions in farmer's per acre water use. Short-term leases are less costly than long-term leases

Mentoring is used in many fields to prepare graduate students for a professional career. This study focuses on mentoring of Ph.D. students in agricultural economics, including the effects of mentoring on expected research output and students' satisfaction with time spent with their major professor. The sink-or-swim mentoring method seems to create the most discord among students and also negatively influences expected research output. The students' gender and citizenship seem to also impact expected output.
