The electromagnetic Nucleon to Delta transition in Chiral Effective Field Theory
We present a calculation of the three complex form factors parametrizing the
nucleon to Delta transition matrix element in the framework of chiral effective
field theory with explicit Delta degrees of freedom. The interplay between
short and long range physics is discussed and estimates for systematic
uncertainties due to higher order effect are given.Comment: Talk given at the 2nd international workshop "Shape of Hadrons",

TESTING FOR CHANGES IN THE PRICE ELASTICITY OF RESIDENTIAL ELECTRICITY DEMAND
The demand for electricity in the residential sector is estimated to have become less elastic for the recent period of rising real prices as compared to earlier periods of stable or falling real price. Several possible reasons for this are investigated and we conclude that demand appears to be asymmetric with respect to price in both the short and long run. We then examine whether or not this is an important factor for forecast accuracy and public policy.Demand and Price Analysis, Resource /Energy Economics and Policy,
Chiral Analysis of the Generalized Form Factors of the Nucleon
We apply the methods of Chiral Perturbation Theory to the analysis of the
first moments of the Generalized Parton Distributions in a Nucleon, usually
known as generalized form factors. These quantities are currently also under
investigation in Lattice QCD analyses of baryon structure, providing simulation
results at large quark masses to be extrapolated to the "real world" via Chiral
Effective Field Theory. We have performed a leading-one-loop calculation in the
covariant framework of Baryon Chiral Perturbation Theory (BChPT), predicting
both the momentum and the quark-mass dependence for all the vector and axial
(generalized) form factors. In particular we discuss the results for the limit
of vanishing four-momentum transfer where the GPD-moments reduce to the well
known moments of Parton Distribution Functions (PDFs). We fit our results to
available lattice QCD data, extrapolating down to the physical point. We
conclude by presenting outstanding results from a combined fit to different
GPDs-moments.Comment: 7 pages, 4 figures, Proceedings of Lattice 2007 (July 30 - 4 August

How Can We Make Our Research More Relevant? Bridging the Gap between Workplace Changes and Business Communication Research
The article of record as published may be located at http://dx.doi.org/10.1177/0021943607302193Some management scholars argue that academic literature is becoming less and less relevant to practicing
managers. Thomas posits that the same will be true for business communication if scholars do not venture
into the field and connect with those who “do” business communication. As organizations shift from manufacturing
to service jobs, expand their operations overseas, manage “talent” more strategically, and alter
traditional bureaucratic structures, business communication is becoming increasingly intercultural, virtual,
horizontal, strategic, and change focused. Yet it is not clear that the business communication literature is
keeping pace. Examples of Thomas’s work in interagency collaboration, electronic mail overload, and
strategic communication demonstrate possibilities for gaining access and studying communication dilemmas
that face practicing managers. Bridging the academic-practitioner gap is a way to build face validity
in the business world as well as help academics to develop better theories about workplace communication

Bournemouth’s ‘Big ReThink’ Project: An arts-based model for change in a university
Change is seldom easy and finding novel approaches that will increase the effectiveness of the process, engage all partners throughout and lead to a difference in culture at the end, adds additional challenge. Creative solutions, using arts-based methods, were seen as a positive way to bring about a reorganisation in a large school in a university. Bournemouth University’s Kip Jones and Gail Thomas report on a process that drew on the underpinning philosophy of arts-based ‘Oblique Strategies’. This was undertaken to bring colleagues together innovatively and constructively to be part of the change process
