Hebrews- A Rhetorical Study

The present study treats of the Epistle to the Hebrews almost purely from the point of view of external form and is preliminary to a more general study of the whole subject of style and language in the New Testament. If it presents many matters of detail that are more or less tedious and call for patience one must bear in mind that it is only by the examination of details that one may come to a reasonably safe conclusion about principles. Even a cursory study of the works of literary critics will demonstrate the necessity of the warning that the general impression of an author which one gets after a comparatively long study of him may not be a true one. That impression may be colored by past experience or by prejudice, in other words, may represent a purely personal idea of excellence. In fact, the literary critic and, in particular, the student of Greek, must continually guard against seeing in an author only what he wishes to see and making his work only the instrument for demonstrating the truth of a prejudice

Rhetoric in the New Testament: The Diction in Romans and Hebrews

Oratory, as a general term, is properly defined as the power to sway an audience by eloquent speech. As far as is known, the art of such effective public speaking was first studied and taught in Greece, where it was called rhetoric. One of the early teachers of rhetoric in this proper sense was Gorgias, the Greek sophist, who brought his art to Athens in 427 B. C. from his native city of Leontini in Sicily. He afterwards settled in Athens, where he continued the practice and teaching of rhetoric. Therefore it is generally agreed that Gorgias is the creator of a new artistic medium-Attic prose - which he developed \u27into a somewhat artificial and flowery mode of expression

A Demonstration of LISA Laser Communication

Over the past few years questions have been raised concerning the use of laser communications links between sciencecraft to transmit phase information crucial to the reduction of laser frequency noise in the LISA science measurement. The concern is that applying medium frequency phase modulations to the laser carrier could compromise the phase stability of the LISA fringe signal. We have modified the table-top interferometer presented in a previous article by applying phase modulations to the laser beams in order to evaluate the effects of such modulations on the LISA science fringe signal. We have demonstrated that the phase resolution of the science signal is not degraded by the presence of medium frequency phase modulations.Comment: minor corrections found in the CQG versio

NASA's Gravitational - Wave Mission Concept Study

With the conclusion of the NASA/ESA partnership on the Laser Interferometer Space Antenna (LISA) Project, NASA initiated a study to explore mission concepts that will accomplish some or all of the LISA science objectives at lower cost. The Gravitational-Wave Mission Concept Study consisted of a public Request for Information (RFI), a Core Team of NASA engineers and scientists, a Community Science Team, a Science Task Force, and an open workshop. The RFI yielded were 12 mission concepts, 3 instrument concepts and 2 technologies. The responses ranged from concepts that eliminated the drag-free test mass of LISA to concepts that replace the test mass with an atom interferometer. The Core Team reviewed the noise budgets and sensitivity curves, the payload and spacecraft designs and requirements, orbits and trajectories and technical readiness and risk. The Science Task Force assessed the science performance by calculating the horizons. the detection rates and the accuracy of astrophysical parameter estimation for massive black hole mergers, stellar-mass compact objects inspiraling into central engines. and close compact binary systems. Three mission concepts have been studied by Team-X, JPL's concurrent design facility. to define a conceptual design evaluate kt,y performance parameters. assess risk and estimate cost and schedule. The Study results are summarized

Accuracy of parameter estimation of gravitational waves with LISA

LISA is a space-borne, laser-interferometric gravitational-wave detector currently under study by the European Space Agency. We give a brief introduction about the main features of the detector, concentrating on its one-year orbital motion around the Sun. We compute how the amplitude as well as the phase of a gravitational wave are modulated due to this motion by transforming an arbitrary gravitational-wave signal in a reference frame that is rigidly fixed to the arms of the detector. To see how LISA works the detector response to a gravitational wave which is purely monochromatic in the barycentric frame will be discussed. A brief review of the theory of parameter estimation, based on the work of Finn and Cutler, will be given. Following this theory the detection of a gravitational-wave signal buried in detector noise was simulated numerically. We interpret the results of this simulation to determine the angular resolution of LISA

A life lived in classrooms : a feminist personal narrative

Dissertation supervisor: Dr. Jennifer Hart.Includes vita.This project offers a counter narrative to some accepted theories regarding graduate learning practices. By using Scholarly Personal Narrative to present my classroom experience I consider how knowledge is produced in higher education. I suggest that the use of feminist theory, postmodernism, and disability studies combined with other higher education theories may expand the limits of current graduate education. This project suggests that my story is useful to the field of higher education and graduate studies, and that by making intentional connections between higher education and feminist theory as well disability studies, new perspectives can emerge about how higher education practices regarding instruction, administration, and policy can be created.Includes bibliographical references (pages 185-202)

Real-time phasefront detector for heterodyne interferometers

We present a real-time differential phasefront detector sensitive to better than 3 mrad rms, which corresponds to a precision of about 500 pm. This detector performs a spatially resolving measurement of the phasefront of a heterodyne interferometer, with heterodyne frequencies up to approximately 10 kHz. This instrument was developed as part of the research for the LISA Technology Package (LTP) interferometer, and will assist in the manufacture of its flight model. Due to the advantages this instrument offers, it also has general applications in optical metrology
