Fractal Location and Anomalous Diffusion Dynamics for Oil Wells from the KY Geological Survey
Utilizing data available from the Kentucky Geonet (KYGeonet.ky.gov) the
fossil fuel mining locations created by the Kentucky Geological Survey
geo-locating oil and gas wells are mapped using ESRI ArcGIS in Kentucky single
plain 1602 ft projection. This data was then exported into a spreadsheet
showing latitude and longitude for each point to be used for modeling at
different scales to determine the fractal dimension of the set. Following the
porosity and diffusivity studies of Tarafdar and Roy1 we extract fractal
dimensions of the fossil fuel mining locations and search for evidence of
scaling laws for the set of deposits. The Levy index is used to determine a
match to a statistical mechanically motivated generalized probability function
for the wells. This probability distribution corresponds to a solution of a
dynamical anomalous diffusion equation of fractional order that describes the
Levy paths which can be solved in the diffusion limit by the Fox H function
ansatz.Comment: : 8 pages, 3 figures, AIPG Conference Meeting, Grand Junction CO,

Fractional Quantum Hall Physics in Jaynes-Cummings-Hubbard Lattices
Jaynes-Cummings-Hubbard arrays provide unique opportunities for quantum
emulation as they exhibit convenient state preparation and measurement, and
in-situ tuning of parameters. We show how to realise strongly correlated states
of light in Jaynes-Cummings-Hubbard arrays under the introduction of an
effective magnetic field. The effective field is realised by dynamic tuning of
the cavity resonances. We demonstrate the existence of Fractional Quantum Hall
states by com- puting topological invariants, phase transitions between
topologically distinct states, and Laughlin wavefunction overlap.Comment: 5 pages, 3 figure

The Workplace Relevance of the Liberal Arts Political Science BA and How It Might Be Enhanced: Reflections on an Exploratory Survey of the NGO Sector
Reflecting on a survey of employees of NGOs based in Ontario, Canada, the article considers two questions: How well are our BA programs preparing students for the workplace? Can we enhance workplace relevance without sacrificing our commitment to liberal education? Key findings are presented, including the BA continues to be a desired and employable degree and skills associated with it are valued; employers are not convinced that graduates with BAs necessarily possess these skills; and respondents associate their formal education with individual skills and extracurricular activities with interpersonal skills. Three strategies to enhance the workplace relevance of BA programs without sacrificing liberal education are suggested, and faculty are encouraged to think more holistically about their BA programs and what students need from them
