Abraham Lincoln and the American Romantic Writers: Embodiment and Perpetuation of an Ideal

Description: The American Romantic writers laid a broad foundation for the historic and heroic Abraham Lincoln who has evolved as our national myth. The writers were attracted to Lincoln by his eloquent expression of the body of ideals and beliefs they shared with him, especially the ideal of individual liberty and the belief that achievement of the ideal would bring about an amelioration of the human condition. The time, place and conditions in which they lived enhanced the attraction, and Lincoln's able leadership during the Civil War strengthened their estimation of him. His martyrdom was the catalyst which enabled the Romantic writers to lay the foundation of the Lincoln myth which has made his name synonymous with individual freedom everywhere even today.

Acceleration of electrons using an inverse free electron laser auto- accelerator

Description: We present data from our study of a device known as the inverse free electron laser. First, numerical simulations were performed to optimize the design parameters for an experiment that accelerates electrons in the presence of an undulator by stimulated absorption of radiation. The Columbia free electron laser (FEL) was configured as an auto-accelerator (IFELA) system; high power (MW`s) FEL radiation at {approximately}1.65 mm is developed along the first section of an undulator inside a quasi-optical resonator. The electron beam then traverses a second section of undulator where a fraction of the electrons is accelerated by stimulated absorption of the 1.65 mm wavelength power developed in the first undulator section. The second undulator section has very low gain and does not generate power on its own. We have found that as much as 60% of the power generated in the first section can be absorbed in the second section, providing that the initial electron energy is chosen correctly with respect to the parameters chosen for the first and second undulators. An electron momentum spectrometer is used to monitor the distribution of electron energies as the electrons exit the IFELA. We have found; using our experimental parameters, that roughly 10% of the electrons are accelerated to energies as high as 1100 keV, in accordance with predictions from the numerical model. The appearance of high energy electrons is correlated with the abrupt absorption of millimeter power. The autoaccelerator configuration is used because there is no intense source of coherent power at the 1.65 mm design wavelength other than the FEL.

The Activities of Disaster Relief Organizations During the Permanent Housing Phase of Recovery: a Case Study Analysis

Description: This study investigates the recovery efforts provided for low income and ethnic minority populations by organizations during the permanent housing phase of recovery in Watsonville, California, following the Loma Prieta earthquake of October 17, 1989. The case study format is used to discover what activities were performed and why each organization chose to perform them. Dynes and Quarantelli's (1968) typology of organization is used to explain how and why established, expanding, extending and emergent organizations participated in the recovery efforts. The findings indicate that the type of organization dictated the kind of tasks each organization performed. Organizations maintained activities during recovery for which they had experience, expertise and proficiency.

Alcoholism and the Family: The Destructive Forces in Hardy's Tess of the D'urbervilles

Description: This study examines the forces which shaped the main character--Tess Durbeyfield--in Hardy's novel in terms of the effects which her alcoholic family had upon her mental and emotional potential and which ultimately become the determining factors in her self-destruction. Using the elements and patterns set forth in the literature regarding the dynamics of the alcoholic family, I attempt to show that Hardy's novel may best be understood as the story of a woman whose life and destiny are controlled by the consequences of her father's alcoholism. This interpretation seems to account best for many elements of the novel, such as Tess's destruction, and provides a rich appreciation of Hardy's technique and vision.

The Amalgamation of Three-Dimensional and Two-Dimensional Processes

Description: Although drawing had offered me many avenues for image exploration and mark making, it lacked the actual physical relief surface that was a natural part of the printmaking plate process (i.e., intaglio plates or relief surfaces). Sculpture allowed the images and marks to be realized dimensionally in the round; therefore, the images became objects.

An Analysis of Factors Associated with Voluntary Disclosure of Management's Responsibilities for Internal Control

Description: The purpose of this study was to identify company characteristics associated with the presence of disclosures regarding internal control in the annual report. Gibbins, Richardson and Waterhouse [1990] have developed a framework from which to examine financial disclosure,. These authors define two dimensions of a company's disclosure position; opportunism and ritualism. I examined the association between variables representing the dimensions identified by these authors and a company's decision regarding disclosure of a management report on internal control. I compared specific characteristics of companies disclosing this information to those of companies not disclosing. The dependent variable represented the presence or absence of disclosure. I used logit analysis to test the significance of the chosen characteristics relative to the decision to include or exclude a management report on internal control in the annual report. My results were consistent with the existence of ritualism with respect to this issue. Reporting on internal controls was associated with membership in the Financial Executives Institute, auditor choice, certain industry designations and prior inclusion of such a report. FEI membership was closely related to initial reporting decisions as well'. I found evidence of opportunism as well. The likelihood of reporting on internal controls was related to company size (and presumably control strength), and growth rates. I also found an association between reporting and the issuance of publicly traded securities in the succeeding year and more moderate levels of debt relative to an industry average. In addition, I found that initial reporting decisions were associated with external events relating to potential legislation of the reporting issue. This research provides insight into the corporate response to reporting on internal controls.

An Analysis of Factors in the Adoption or Non-Adoption of Videodisc Technology in North American Academic and Special Libraries

Description: The researcher identified 37 independent variables to study their effect on the two dependent variables, the acquisition of videodiscs and the functions for which videodisc programs were acquired. The literature of the applications of videodisc technology in libraries, museums, education and industry, as well as related issues concerning interactive video, were presented in Chapter 2. Using the diffusion of innovation theory of Everett Rogers as a guide, the researcher constructed a questionnaire. Valid responses totaled 462 from management of all types of academic libraries and from special libraries other than non-academic law, military, veterans' hospital, and church libraries. The following conclusions were made from the results: there were significant correlations between having videodiscs and perceptions of greater benefits than costs, appropriateness of videodisc programs for libraries' objectives or curricula, seeing videodiscs as an enhancement of an existing library technology, collection of videocassettes, and ability to raise funds from slack resources. The size of the libraries' materials and equipment budgets had some significance, but it was not consistently significant, as it was for the above-mentioned factors, at the p < .01 level. Lack of in-house recording ability did not impose a barrier on adoption of discs among respondents. Full--motion, full-screen video was not seen as very important for future multimedia use.

An analysis of monojet data in p{bar p} collisions at {radical}s = 1.8 TEV

Description: An analysis is presented of events with a single jet and significant missing transverse energy selected from 4.7 pb{sup {minus}1} of data collected at the Fermilab Tevatron with the CDF detector. The goal is to identify events of the type p{bar p} {yields} Z{sup 0} + jet; Z{sup 0} {yields} {nu}{bar {nu}}. Event selection and backgrounds are discussed. The number of observed monojet events is compared to the number of observed Z{sup 0} {yields} e{sup +}{sup {minus}} events in which the Z{sup 0} is accompanied by a jet. We measure the number of light neutrino species to be N{sub {nu}} = 2.2{plus_minus}1.5 and we place an upper limit on the number of neutrino species at N{sub {nu}} < 5 (90% C.L.).

An analysis of multiple particle settling for LMR backup shutdown systems

Description: Backup shutdown systems proposed for future LMRs may employ discreet absorber particles to provide the negative reactivity insertion. When actuated, these systems release a dense packing of particles from an out-of-core region to settle into an in-core region. The multiple particle settling behavior is analyzed by the method of continuity waves. This method provides predictions of the dynamic response of the system including the average particle velocity and volume fraction of particles vs. time. Although hindered settling problems have been previously analyzed using continuity wave theory, this application represents an extension of the theory to conditions of unrestrained settling. Typical cases are analyzed and numerical results are calculated based on a semi-empirical drift-flux model. For 1/4-inch diameter boron-carbide particles in hot liquid sodium, the unrestrained settling problem assumes a steady-state solution when the average volume fraction of particles is 0.295 and the average particle velocity is 26.0 cm/s.

An Analysis of Reading Preferences of Pilots to Develop a Book List for Aviation Education

Description: This study proposed to develop a list of aviation books that experienced pilots consider inspirational and motivational which could be used in an aviation literature course in adult education. Survey results showed the subject pilots had a positive attitude toward reading and flying, but there was little correlation (r = .35) between the two. This suggests that something else influenced the reading of the sample books. The pilot resondents suggested 269 books for use in a course. This book list will need additional refining and syntopical sorting before use as a canon in an aviation education course.

An Analysis of the Accounting System of the Quincy Mining Company: 1846-1900

Description: This historical study examines the evolution of the accounting system of the Quincy Mining Company between 1846 and 1900. The external financial reporting practices and internal accounting procedures of the firm are defined and interpreted in the context of three time periods that portray the formation, growth and maturation of the firm. Each period reflects unique economic and social conditions that are associated with changes in the firm's accounting system. A cross temporal analysis of these changes highlights three factors: the relationship between the accounting system and the labor force, the emergence of accounting as a control mechanism and the diminishing informational content of the firm's annual reports. Primary sources are used to document the perspectives of the Quincy management and to assess the motivations for accounting processes such as internal control, auditing procedures, responsibility centers and other managerial practices. This study addresses the inherent nature of accounting information and its relationship to the economic and social environment of an individual firm in the nineteenth century.

An analytic determination of beta poloidal and internal inductance in an elongated tokamak from magnetic probe measurements

Description: Analytic calculations of the magnetic fields available to magnetic diagnostics are performed for tokamaks with circular and elliptical cross sections. The explicit dependence of the magnetic fields on the poloidal beta and internal inductances is sought. For tokamaks with circular cross sections, Shafranov`s results are reproduced and extended. To first order in the inverse aspect ratio expansion of the magnetic fields, only a specific combination of beta poloidal and internal inductance is found to be measurable. To second order in the expansion, the measurements of beta poloidal and the internal inductance are demonstrated to be separable but excessively sensitive to experimental error. For tokamaks with elliptical cross sections, magnetic measurements are found to determine beta poloidal and the internal inductance separately. A second harmonic component of the zeroth order field in combination with the dc harmonic of the zeroth order field specifies the internal inductance. The internal inductance in hand, measurement of the first order, first harmonic component of the magnetic field then determined beta poloidal. The degeneracy implicit in Shafranov`s result (i.e. that only a combination of beta poloidal and internal inductance is measurable for a circular plasma cross section) reasserts itself as the elliptic results are collapsed to their circular limits.

An analytical method for estimating the {sup 14}N nuclear quadrupole resonance parameters of organic compounds with complex free induction decays for radiation effects studies

Description: The use of {sup 14}N nuclear quadrupole resonance (NQR) as a radiation dosimetry tool has only recently been explored. An analytical method for analyzing {sup 14}N NQR complex free induction decays is presented with the background necessary to conduct pulsed NQR experiments. The {sup 14}N NQR energy levels and possible transitions are derived in step-by-step detail. The components of a pulsed NQR spectrometer are discussed along with the experimental techniques for conducting radiation effects experiments using the spectrometer. Three data analysis techniques -- the power spectral density Fourier transform, state space singular value decomposition (HSVD), and nonlinear curve fitting (using the downhill simplex method of global optimization and the Levenberg-Marquart method) -- are explained. These three techniques are integrated into an analytical method which uses these numerical techniques in this order to determine the physical NQR parameters. Sample data sets of urea and guanidine sulfate data are used to demonstrate how these methods can be employed to analyze both simple and complex free induction decays. By determining baseline values for biologically significant organics, radiation effects on the NQR parameters can be studied to provide a link between current radiation dosimetry techniques and the biological effects of radiation.

Anger and Hostility Measures: Effects of Social Desirability

Description: Individuals responding in a socially desirable (SD) fashion, rather than in a manner that reflects their true behavior, has been a problem for self-report questionnaires since their inception. The purpose of this study was to examine the hypothesis that the probability an item is endorsed on a self-report measure of anger is directly proportional to the rated SD of that item. Eighty-two subjects completed the Buss-Durkee Hostility Inventory (BDHI), the Profile of Moods State (POMS), and the State- Trait Anger Expression Inventory (STAXI). A probability of endorsement was computed for each of the measures' items. Twenty additional subjects rated the measures' items for SD. Each item's SD rating was paired with the probability the item was endorsed to produce a correlation coefficient for each measure. Results strongly support the stated hypothesis. Directions for future research are discussed.

Aortic Baroreceptor Reflex Control of Blood Pressure: Effect of Fitness

Description: Aortic baroreflex (ABR) control of blood pressure was examined in 7 untrained (UT) and 8 endurance exercise trained (EET) young men. ABR control of blood pressure was determined during a steady state phenylephrine infusion to increase mean arterial pressure 10-15 mmHg, combined with positive neck pressure to counteract the increased carotid sinus transmural pressure, and low levels of lower body negative pressure to counteract the increased central venous pressure. Functioning alone, the ABR was functionally adequate to control blood pressure. However, ABR control of HR was significantly diminished in the EET subjects due solely to the decrease in the ABR sensitivity. The persistent strain from an increased stroke volume resulting from endurance exercise training could be the responsible mechanism.

Application of photothermal deflection spectroscopy to electrochemical interfaces

Description: This dissertation discusses the theory and practice of Photothermal Deflection Spectroscopy (PDS, which is also known as probe beam deflection spectroscopy, PBDS, probe deflection technique, and mirage effect spectroscopy) with respect to electrochemical systems. Much of the discussion is also relevant to non-electrochemical systems. PDS can measure the optical absorption spectrum of interfaces and concentration gradients in the electrolyte adjacent to the electrode. These measurements can be made on a wide variety of electrode surfaces and can be performed under dynamic conditions. The first three chapters discuss the theory of the phenomena that can be detected by PDS, and the equipment used in a PDS system. A ``secondary gradient technique`` is proposed, which places the probe beam on the back of an electrode. The results of a numerical model yield a method for determining the offset of the probe beam from the electrode surface based on the frequency response of the PDS signal. The origin and control of noise in the PDS signal are discussed. A majority of the signal noise appears to be acoustic in origin. The electrochemical oxidation of platinum is used to demonstrate that PDS has sub-monolayer sensitivity necessary to study interfacial chemistry. The results allow us to propose a two-reaction oxidation mechanism: the platinum is electrochemically oxidized to form platinum dihydroxide and dehydrated by a non-electrochemical second-order reaction. The final chapter discusses the relation of PDS to similar and competing techniques, and considers possibilities for the future of the technique.

Application of Synthetic Peptides as Substrates for Reversible Phosphorylation

Description: Two highly homologous synthetic peptides MLC(3-13) (K-R-A-K-A-K-T-TK-K-R-G) and MLC(5-13) (A-K-A-K-T-T-K-K-R-G) corresponding to the amino terminal amino acid sequence of smooth muscle myosin light chain were utilized as substrates for protein kinase C purified from murine lymphosarcoma tumors to determine the role of the primary amino acid sequence of protein kinase C substrates in defining the lipid (phosphatidyl serine and diacylglycerol) requirements for the activation of the enzyme. Removal of the basic residues lysine and arginine from the amino terminus of MLC(3-13) did not have a significant effect on the Ka value of diacylglycerol. The binding of effector to calcium-protein kinase C appears to be random since binding of one effector did not block the binding of the other.

Assessing the Object Relations of Sexually Abused Females

Description: The TAT stories of 38 sexually abused females between the ages of 5 and 18 years and a clinical group of 26 females with no recorded history of abuse were analyzed using the Object Relations and Social Cognitions TAT Scoring System (Westen et al., 1985). Subjects in the sexual abuse group showed significantly lower mean scores on a scale measuring affect-tone of relationship paradigms and on a scale measuring complexity of representations of people. In addition, pathological responses were given significantly more often by sexual abuse victims on the complexity of representations of people scale. Thus, sexually abused children showed more primitive and simple characterizations of people and more negative, punitive affect in their representations. Moreover, these results were independent of age, race, and intelligence. Group differences are discussed in terms of object relations development.
