Fermion Determinants: Some Recent Analytic Results

The use of known analytic results for the continuum fermion determinants in QCD and QED as benchmarks for zero lattice spacing extrapolations of lattice fermion determinants is proposed. Specifically, they can be used as a check on the universality hypothesis relating the continuum limits of the na\"{\i}ve, staggered and Wilson fermion determinants.Comment: 8th Workshop on Non-Perturbative QCD, 7-11 June 2004, Pari

Regret Aversion and False Reference Points in Residential Real Estate

This study empirically exams the combination of regret aversion and false reference points in a residential real estate context. Survey respondents were put in a hypothetical situation, where they had purchased an investment property several years ago. Hindsight knowledge about a foregone all time high was introduced. As hypothesized, respondents on average expressed higher regret if they had actively failed to sell at the all time high (commission scenario) than if they had simply been unaware of the potential gain (omission scenario). Women were found to be more susceptible to regret aversion and false reference points than men.

Digging Deeper: James Connolly in America

This project continued research into James Connolly\u27s time in America from 1902-1910. It focused on primary sources in the hopes to unearth things not found in the secondary writing on Connolly’s activities during this influential time. The O’Brien papers are an eclectic collection of primary documents from Connolly’s life, including letters between James Connolly and his friend John Matheson, correspondence with other socialists, and some of Connolly’s own writing. The New York Call was a daily socialist newspaper that contains ads for Connolly’s lectures and his magazine, The Harp, as well as meetings of his organization, the Irish Socialist Federation. Through these primary sources and others, more of James Connolly’s activities and perspectives during his time in America come to light

Epitaxial undoped indium oxide thin films: Structural and physical properties.

Indium oxide thin films were grown by the pulsed electron beam deposition method on c-cut sapphire substrates at 10−2 mbar oxygen pressure and temperature up to 500 1C. Such conditions lead to the formation of dense, smooth and stoichiometric In2O3 films, with the cubic bixbyite structure. Epitaxial thin films were obtained at substrate temperatures as low as 200 1C. Pole figure measurements indicate the existence of (111) oriented In2O3 crystallites with different in-plane symmetry, i.e. three-fold and six-fold symmetry. The origin of this effect may be related to the specificities of the growth method which can induce a large disorder in the oxygen network of In2O3, leading then to a six-fold symmetry in the (111) plane of the bixbyite structure. This temperature resistivity behaviour shows metallic conductivity at room temperature and a metal– semiconductor transition at low temperature for In2O3 films grown at 200 1C, while the classical semiconductor behaviour was observed for the films grown at 400 and 500 1C. A maximum mobility of 24.7 cm2/V s was measured at 200 1C, and then it falls off with improving the crystalline quality of films. The optical transparency is high (480%) in a spectral range from 500 nm to 900 nm

A Study of How Flight Instructors Assess Flight Maneuvers and Give Grades: Inter-rater Reliability of Instructor Assessments

This article discusses calibration of flight instruction to an academic institution’s “gold standard”. Flight instructors reviewed four lessons within the private pilot curriculum. Each lesson required rating four maneuvers and assigning an overall letter grade. Data was compared to the gold standard set by flight faculty from the institution. Initial data revealed instructors with one year or less of experience had less agreement to the gold standard. A curriculum to rate maneuvers and grade lessons was developed and practice sessions occurred in instructor meetings starting Fall 2013. Post-test results show improvement in agreement in one year or less experienced group
