In particular, bidding is a mechanism whereby companies compete for contracts; when functioning well, the process rewards both the quality of the proposal, and the “reasonableness” of the quote. This way, both the company and the public win. The bidding process requires a fair and transparen...

In this article art is used as inquiry to ask powerful questions, untangle paradoxes, and help us navigate loss grief in the Anthropocene. Several central questions are considered animated through narrative poetry. How do we live poetically (Leggo, 2005) a world that need exploit order survive? engage more-than-human full of ambiguity paradox? might nature become teacher or mentor (Jickling et ...

Funded by grants from the National Science (DUE 0817461 and 0817498), the first cohort of engineering and engineering technology colleges gathered in the summer of 2010 to work with Purdue University and Alverno College faculty on curriculum development for student learning outcomes, including Engineer of 2020 attributes. The overarching goals of this panel are to (1) present the progress of th...

The Arctic and sub-Arctic environments have seen a rapid growth of shrub vegetation at the expense of the Arctic tundra in recent decades. In order to develop better tools to assess and understand this phenomenon, the sensitivity of multi-polarized SAR backscattering at C and X band to shrub density and height is studied under various conditions. RADARSAT-2 and TerraSAR-X images were acquired f...

We review the status of searches for Supersymmetry at the Tevatron Collider. After discussing the theoretical aspects relevant to the production and decay of supersymmetric particles at the Tevatron, we present the current results for Runs Ia and Ib as of the summer of 1997.
