An Analysis Of The Effects Of Background Variables On Attitudes And Policy At The Bonneville Power Administration, Philip George Millam

Dissertations and Theses

The question is asked whether or not background, education, and training of middle and upper level bureaucratic personnel affects policy outcomes. The Bonneville Power Administration (BPA) serves as the agency examined. A written questionnaire sent to a random sample of BPA executives sought data on background variables with the intent of making comparisons. Most BPA executives are found to share very similar education and training backgrounds – namely, engineering studies at Northwest state universities. Also, attitudes measured are found to be more similar than different on most issues for the agency as a whole. This phenomenon is explained in terms …

The low-loss cavity modes are related to ordinary gaussian beam modes. Two limiting forms are the disk laser and the tube laser, and some applications are considered.

Factors Affecting The Population Of Raptorial Birds On Sauvie Island, Oregon, Jeffry Gottfried

Dissertations and Theses

This study is an analysis of the various factors affecting the population of raptorial birds on Sauvie Island, Oregon. A census of diurnal and nocturnal raptors was carried out along with an analysis of food habits. Once the major prey species were determined they were censused, and the effects of the land management practices on their numbers was investigated. In addition, 100 randomly selected nest boxes were sampled so as to determine the extent to which raptors were making use of them. Red-tailed hawk and Great Horned Owl nests were located.

It was found that four diurnal raptors and three …

Postcensal Population Estimates For Oregon Counties: An Evaluation Of Selected Methods, Guy Jeffrey Barnes

Dissertations and Theses

This study evaluates the results of three widely used methods for preparing postcensa estimates of counties. The methods are Census Bureau’s Component Method II, the Ratio Correlation Method and the Bogue-Duncan Composite Method. Hypotheses based upon empirical generalizations from previous comparative studies are tested. Statistical tools used are Average Percent Deviation (without regard to sign) and Standard Deviation of Percent Errors. Directional bias and frequency of extreme error are also examined. Evaluations are conducted of the accuracy of the estimates for groups of counties stratified in terms of density and growth rate dimensions. With few exceptions, Ratio Correlation produces consistently …

Decay Of Multiple Spin Echoes In Dipolar Solids, C. H. Wang, John D. Ramshaw

Physics Faculty Publications and Presentations

In this paper we derive a general expression describing the evolution of the transverse nuclear-spin magnetization for the Ostroff-Waugh multiple-spin-echo experiment in dipolar solids. Our approach consists of expressing the formula for the magnetization at even echoes in a form resembling an ordinary time-correlation function, and then evaluating this quantity by means of Zwanzig's projection-operator technique. For long times, we show that under certain conditions the echo envelope decays exponentially, in agreement with experiment. A general expression is obtained for the time constant T^* associated with the decay. This result may be used to generate an expansion of 1T …

Existence Of The Dielectric Constant In Rigid-Dipole Fluids: The Direct Correlation Function, John D. Ramshaw

Physics Faculty Publications and Presentations

The question of whether the dielectric constant ε exists (is well defined) for a finite fluid system of rigid dipolar molecules is reconsidered and reformulated. It is found that this question can most simply be expressed in terms of the behavior of the position‐ and orientation‐dependent direct correlation function c(r₁,ω₁; r₂, ω₂). It is shown that ε exists if c satisfies the following two conditions: (a) c~–φ/kT for |r₁–r₂|>σ, where φ is the dipole‐dipole potential and σ is a length which is large microscopically but small macroscopically. …

New Method For Generating Density Expansions, John D. Ramshaw

Physics Faculty Publications and Presentations

The calculus of finite differences is used to develop a new method for expressing the thermodynamic limit of a reasonably arbitrary statistical?mechanical average as a power series in the number density ?. The method is simple, straightforward, and purely analytic: it involves no intermediate expansion in powers of the activity and it avoids the use of graph theory. Moreover, the method is developed independently of the prescription for computing the statistical average, a fact which lends to the results an especially wide range of applicability. In particular, these results may be used in classical or quantum statistical mechanics, for intermolecular …

Kinetics Of The Cope Rearrangement Of 3,4-Diphenylhexa-1,5-Diene, Harlan Albert Jerome Berg

Dissertations and Theses

Kinetics investigations of the thermal Cope rearrangement of meso- and dl-3,4-diphenylhexa-1,5-dienes were undertaken in order to gain information about the transition states for these reactions by determining the appropriate enthalpies and entropies of activation. Of particular interest were the activation parameters for the meso compounds' rearrangement as it represents the only known example in which both four- and six-centered transition states are of comparable energy.

Kinetics of the dl isomers' rearrangement in the temperature range 90-110° were determined using 5 X 10^-5 M solutions of the olefin in heptane contained within sealed Pyrex ampules. Extents of reaction …

Measurements Of The Mössbauer Fraction In Chromium, B. Frederick Brace Jr.

Dissertations and Theses

Precision measurements of the Mossbauer fraction of Fe57 in chromium were made using the black absorber technique over a range of temperatures from 78K to 792K. Because of uncertainty in corrections at high temperatures, only the data collected from 78K to 600K was used in analyzing the results.

The f values were analyzed in terms of a Debye approximmation. This analysis of the data yielded a theoretical fit which was based on two adjustable parameters (a Debye temperature of 438K and an anharmonicity parameter of 2 x 10^-4K^-1).

The f measurements were also analyzed using a …

Black Studies As An Agent Of Social Change On The Structural Level At Selected Colleges And Universities, Vincent Van Davis

Dissertations and Theses

In a relatively short period of time American higher education has witnessed the development of numerous black studies programs and departments. These new academic endeavors have been instrumental in producing structural changes in the institutions of higher education. Recently higher education has attempted to assess the progress of black studies programs and departments within their structures. This has been done with some attempt to assess the past of black studies as well as project the future of black studies within higher education.

Due to the hurried developmental process of black studies programs, which led to the establishment of black studies …

Johann Adam Moehler: The Method Of Historical Theology, Christina Maria Crose

Dissertations and Theses

This thesis is a study of Johann Adam Moehler's critical theology as an achievement in the nineteenth century's quest for a historical methodology. As the first Catholic theologian to apply a critical-historical analysis to the development of doctrine, Moehler is important as both the theologian and as a German historian.

As the theologian, Moehler's efforts to discover the essential meaning of Christian doctrine led him to conclude that doctrine develops within a human context of experience, namely, the Catholic Church. This development of doctrine is possible given the organic nature of the Christian community and its relationship to the divine. …

Moment-Curvature-Thrust Relationships In Hybrid Members, Douglas Wrenn Fiala

Dissertations and Theses

In order to overcome the difficulties encountered in closed form solutions, moment-curvature-thrust relationships are developed for hybrid and nonhybrid cross sections utilizing an open form method. The use of horizontal sectors permits the inclusion of residual stresses and/or nonbilinear stress-strain relationships, if desired. Theoretical and experimental data are compared. Applications to circular tubes and other cross sections are discussed. Results indicate that open form solutions are feasible for calculating moment-curvature-thrust data. Hybrid cross sections are easily treated by open form solutions.

Simulation Of Brain Damage On Bender-Gestalt Test By College Subjects, Arnold Rahn Bruhn

Dissertations and Theses

It is a frequent occurrence in accident cases involving alleged brain injury and attendant damage suits, for the defendant's attorney to charge the plaintiff in the case with malingering. At some time in the court proceedings it i.s also common that the plaintiff's psychologist will testify to the court that his client's brain damage is genuine, not feigned. but heretofore, clinicians have been able to speak to the court only from their own background of clinical experience, and clinicians have been known to disagree. They have not been able to refer to a body of research that has addressed itself …

Complex Systems And The Price-Resource Directive Coordination Procedure, Chamberlain Lambros Foes

Dissertations and Theses

In this thesis, the problem considered is that of linear static optimization of a large system which is composed of a finite number of subsystems, each characterized by its own constraint matrix and objective function.

The total system is itself constrained by resource availabilities and other factors, and its objective function is the mathematical linear sum of the objective function of the subsystems. The total system constraints couple together all the subsystems. The total system is first reformulated as a two-level problem by decoupling the total system constraints utilizing an arbitrary partition of the total system resources and other factors …

Application Of Numerical Analysis To Root Locus Design Of Feedback Control Systems, Steve William Justice

Dissertations and Theses

Many practical problems in the field of engineering become so complex that they may be effectively solved only with the aid of a computer. An effective solution depends on the use of an efficient algorithm. Plotting root locus diagrams is such a problem. This thesis presents such an algorithm.

Root locus design of feedback control systems is a very powerful tool. Stability of systems under the influence of variables can be easily determined from the root locus diagram. For even moderately complex systems of the type found in practical applications, determination of the locus is extremely difficult if accuracy is …

Catechol Effected Dissolution Of Silicate Minerals, James Maurice Kelley

Dissertations and Theses

The chemical properties of guanidinium tris(catecholato)siliconate, [(H₂N)₂C=NH₂]₂[Si(C₆H₄O₂)₃]·XH₂O (0 < X < 1), precipitated from an ammoniacal solution of silica and catechol by adding guanidinium hydrochloride, (H₂N)₂C=NH·HC1, were studied, and infrared, nmr, x-ray powder diffraction, and analytical data were gathered.

This same compound was, upon addition of' (H₂N)₂C=NH·HC1, isolated from 0.25, M aqueous catechol solutions buffered at pH 10 and containing the silicate minerals albite, andradite, muscovite, pyrophyllite, talc, and wollastonite, and also from unbuffered catechol solutions containing wollastonite and andradite.

It is concluded from this work that the formation of an anionic catechol-silicon complex, Si(C₆H₄O₂)₃²⁻, is largely responsible for the dissolution of the minerals mentioned above. From this conclusion, it is proposed that naturally occurring members of the class of organic compounds to which catechol belongs, the aromatic v̲i̲̲c̲-diols, may play …
