Modeling Energy Use and Technological Change for Policy Makers: Campbell Watkins’ Contribution as a Researcher-Practitioner

As an energy-economics modeler, who collaborated with academics while also consulting to government and industry, Campbell Watkins was especially interested in the empirical relationship between energy inputs and economic output. His skills were perfectly suited to this pressing research issue, which first emerged in the mid-1970s as the “energy-capital substitution” controversy. As his publica...

ii DEDICATION To Kimberly

A key issue in software evolution analysis is being able to compute evolutionary change accurately and with rich semantics. This dissertation describes a mathematical framework for enabling accurate computation of semantic evolutionary change. It is based on graphs for representing software semantics, graph transformations for modeling evolution, and effects of graph transformations for capturi...

Perkins IV : An Interview with Kimberly Green

MS. GREEN: Our organization was founded back in the early 1900s, when the federal government first started investing in career and technical education, as a means to interface with each state’s contact person in [what was then called] vocational education. Over time, our organization has grown, but we’ve always maintained that focus of serving states. Our core membership is the state directors ...

On a Conjecture of Watkins

Watkins has conjectured that if R is the rank of the group of rational points of an elliptic curve E over the rationals, then 2 divides the modular parametrisation degree. We show, for a certain class of E, chosen to make things as easy as possible, that this divisibility would follow from the statement that a certain 2adic deformation ring is isomorphic to a certain Hecke ring, and is a comple...
