Offenbach’s Operetta as Performance Practice: A Pedagogical, Dramatic, and Stylistic Role Guide for Pâris in La belle Hélène

This dissertation originated from my personal experience in performing the role of Pâris in Offenbach’s La belle Hélène and the research I conducted in preparation for the performance. Upon examining the score, I discovered the role to contain vocal elements that seemed foreign to my expectations of operatic repertoire. After consulting as many scholarly sources as I could find on the subject, I discovered little to no sense of direction in preparing and performing this unique role or for French operetta as a genre. I decided to compile my experience and research into a usable tool for preparing a French operetta performance practice via a role guide for Pâris. Chapter I gives an introduction of my personal experience with the role and a short historical background of the environment that produced such a work. I also provide a concise breakdown of standard performance practice for French opera and how it relates to my interpretation of Offenbach’s music as a unique French operetta style. Chapter II takes each piece from the opera and provides a detailed guide for successful performance and addresses various eccentricities which are far enough outside the standard repertoire they might incur consternation in the singer. Chapter III contains my concluding remarks on the role and its place in the repertoire, and the subsequent appendix contains a rehearsal breakdown for the most effective practice of the role

Common Law Duty in Negligence Law: The Recent Consolidation of a Consensus on the Expansion of the Analysis of Duty and the New Conservation Liability Limiting Use of Policy Considerations

Without the concept of duty, there is no liability law. Yet, the author demonstrates that although law reviews and other literature contain ample discussion of the legal duty in its various applications, little has been settled with regard the general concept of duty until recently. Professor Lake offers his own account of the concept of duty and offers a 50-state analysis of the general concept of duty, including key decisions that discuss the general concept of duty in negligence law. This article calls upon the American Law Institute to revise the topic of duty to reflect the consensus about its meaning in negligence law now forming among American courts

Rise of Duty and the Fall of In Loco Parentis and Other Protective Tort Doctrines in Higher Education Law, The

The story of twentieth century higher education student safety law\u27 is the gradual application of typical rules of civil liability to institutions of higher education and the decline of insulating doctrines, such as in loco parentis,2 which traditionally protected institutions of higher learning from scrutiny in the legal system. A series of recent events have brought public (and legal) attention to questions about the legal rules governing university responsibility for student injuries.3 In recent times, courts have reversed a long-standing tradition of protecting universities from civil liability for physical injury to students arisin

Development of a collision table for three dimensional lattice gases

Bibliography: pages 92-95.A lattice gas is a species of cellular automaton used for numerically simulating fluid flows. TransGas [9], the lattice gas code currently in use at the CSIR, is based on the FHP-I model [5], and is used to perform various two-dimensional flow simulations. In order to broaden the scope of the applications in which lattice gases can be used locally, the development of a three-dimensional lattice gas capability is required. The first major task in setting up a three dimensional-lattice gas is the construction of an efficient collision rule generator which will determine collision outcomes. For suitability to local applications, the collision rules should be chosen in such a way as to maximise the Reynolds coefficient of the flow, while conserving quantities such as mass and momentum. Part of the task thus becomes an optimisation problem. When expanding from two to three dimensions, the number of possible collision rules increases from 64 to 16777216. If a complete collision rule table is used for determining collision outcomes, storage problems are encountered on the available hardware. Selection and optimisation of collision rules cannot be done by hand when there are so many rules to choose from. Selection of rules is thus non-trivial. The work outlined in this thesis provides the CSIR with a 3-D lattice gas collision table which is well suited to the available hardware capabilities. The necessary theoretical background is considered, and a survey of the literature is presented. Based on the findings of this literature study, various methods of collision outcome determination are implemented which are considered to be suitable to the local needs, while remaining within the constraints set by hardware availability. An isometric collision algorithm, and a reduced collision table are generated and tested. A measure of the overall efficiency of a lattice gas model is determined by two factors, namely the computational efficiency and the implementation efficiency. In testing a collision table, the first is characterised by the rate at which post-collision states can be determined, and depends on the hardware and programming techniques. The second factor can be expressed by means of a number called the Reynolds coefficient, which is defined and discussed in the following chapters. The higher the Reynolds coefficient of a model, the greater the scope of flow regimes which may be simulated using it. Another advantage of having a high Reynolds coefficient is that the simulation time required for a given flow regime decreases as the Reynolds coefficient of the model increases. The overall efficiency of the isometric model is too low to be of practical use, but a significant improvement is obtained by using the method of reduced tables. In the isometric case, the number of collision outcomes that can be determined per second is similar to that of the reduced table, but the Reynolds coefficient is very much lower. Simulation of a flow regime with a Reynolds number of about 100, on a lattice of size 128³, over 20 thousand timesteps, making use of the isometric model, would take of the order of a few years to complete on the currently available hardware. Since the simulation parameters mentioned above are typical of the local requirements for lattice gas simulations, this method is obviously unsatisfactory. The isometric method does however serve as a useful introduction to three-dimensional lattice gas collision rule methods. The reduced collision table has been constructed so that it maintains semi-detailed balance, and the Boltzmann Reynolds coefficient has been calculated. In the reduced collision table model, the efficiency is higher than the isometric case in respect of both the rate at which collision outcomes can be determined, and in terms of the Reynolds coefficient. As a result of these improvements, the simulation time for the exact case mentioned above would reduce to the order of days, on the same hardware. This simulation time is sufficiently low for immediate practical application in the local environment

A note on ADCP-based indirect observations of turbulence

A 70-day data set from bottom-mounted ADCPs on the two sides of the Faroe-Bank Channel was analysed using the recorded flow variance and echo intensity in the deeper reaches of the passage as proxies for turbulence. A consistent picture emerged, not least since the data losses (which were ascribed to turbulence-induced activation of the fish-elimination option in the ADCP software) could be shown to co-vary with the internal M-2 tide affecting the vertical shear, which in turn proved to be correlated with the flow variance

Dark Matter Disc Enhanced Neutrino Fluxes from the Sun and Earth

As disc galaxies form in a hierarchical cosmology, massive merging satellites are preferentially dragged towards the disc plane. The material accreted from these satellites forms a dark matter disc that contributes 0.25 - 1.5 times the non-rotating halo density at the solar position. Here, we show the importance of the dark disc for indirect dark matter detection in neutrino telescopes. Previous predictions of the neutrino flux from WIMP annihilation in the Earth and the Sun have assumed that Galactic dark matter is spherically distributed with a Gaussian velocity distribution, the standard halo model. Although the dark disc has a local density comparable to the dark halo, its higher phase space density at low velocities greatly enhances capture rates in the Sun and Earth. For typical dark disc properties, the resulting muon flux from the Earth is increased by three orders of magnitude over the SHM, while for the Sun the increase is an order of magnitude. This significantly increases the sensitivity of neutrino telescopes to fix or constrain parameters in WIMP models. The flux from the Earth is extremely sensitive to the detailed properties of the dark disc, while the flux from the Sun is more robust. The enhancement of the muon flux from the dark disc puts the search for WIMP annihilation in the Earth on the same level as the Sun for WIMP masses < 100 GeV.Comment: 7 pages, 4 figures, added a short paragraph to the discussion section, conclusions unchanged, published versio

Junctions and thin shells in general relativity using computer algebra I: The Darmois-Israel Formalism

We present the GRjunction package which allows boundary surfaces and thin-shells in general relativity to be studied with a computer algebra system. Implementing the Darmois-Israel thin shell formalism requires a careful selection of definitions and algorithms to ensure that results are generated in a straight-forward way. We have used the package to correctly reproduce a wide variety of examples from the literature. We present several of these verifications as a means of demonstrating the packages capabilities. We then use GRjunction to perform a new calculation - joining two Kerr solutions with differing masses and angular momenta along a thin shell in the slow rotation limit.Comment: Minor LaTeX error corrected.
