ELITE GERMPLASM FOR GMO'S IN BRAZIL: MODELING GOVERNMENT-AGRIBUSINESS NEGOTIATIONS

Advances in agricultural biotechnology have led to interest by agribusiness to license elite germplasm from national programs in developing countries, now in need of funds. Uncertainties about the value of the material have delayed negotiations. This article proposes a method of setting upper (monopoly; no seed saving) and lower (competitive) negotiating bounds on values. The model accounts for (1) annual productivity enhancements, (2) effects on world prices, and (3) obsolescence effects of greater R&D. A demonstration application for soybeans in Brazil, which has completed the preconditions (IPR, biosafety, internal policy), suggests limited private value for public germplasm. The optimal solution is cooperation (licensing).Agribusiness, Research and Development/Tech Change/Emerging Technologies,

COOKIE(X) = 1/2

This poem applies the concept of expected value, denoted E(X), to the context of any limited resources two parties desire. Usually, you divide, I choose keeps pieces equal enough to preempt charges of unfairness. But if one piece is much larger, many distrust the unbiased (in expected value) process of a coin flip giving each person the same chance at the bigger piece and the same cookie amount on average: E(X) = (1/2)p + (1/2)(1-p) = 1/

\u3cb\u3eReader\u27s Response:\u3c/b\u3e Learning about Learning: Moving Beyond a Teacher-Centered Approach

Excerpt: Two articles in the January 2013 issue address the need for teachers to focus on student learning rather than on what the teacher does (Scoufis, 2013) and make learning the object of inquiry (Cerbin, 2013). A big part of making this happen is reducing or eschewing lecture that is one-directional and one-dimensional. This often means that teachers must overcome many habits, biases, or misconceptions about lecture. Like many (if not most) professors, I began my teaching career as a strictly-by-the-book lecturer and has gradually over time worked through his own limitations and prejudices to incorporate more and more active learning strategies, such as classroom voting (Lesser, 2011) or liberating structures such as 1-2-4-whole (Lipmanowicz & McCandless, 2010)
