An analysis procedure is suggested and an example of this procedure for an interval of data is discussed. The influence of the temperature, pressure, rainfall and solid earth tides on the signal is investigated, as well as the correlation between similar channels of the different tilt instruments. The temperature, rainfall and solid earth tides were all …

The Application Of Exact Electrodiffusion Theory To Ion Transport Across Lipid Bilayer Membranes, Scott Cohen

Dissertations and Theses

The question of how ions interact with each other and with the potential energy barrier in thin lipid bilayer membranes has interested investigators for several years. The application of electrodiffusion theory to the study of this question is the central theme of this work. We have calculated current-voltage curves for barriers of various shapes and heights, in each case by means of numerically integrating the exact electrodiffusion equation as well as this same equation in the constant field approximation. We have also calculated the total charge in the membrane for the same conditions under which we have calculated the current-voltage …

Level Of Aspiration And The Type A Coronary-Prone Pattern In Children, Wendy L. Kliewer

Dissertations and Theses

Type A coronary-prone behavior has been recognized as a major risk factor for coronary heart disease. Characterized by extremes of achievement-striving, impatience aggression, and easily aroused hostility, this behavior pattern has been studied extensively in adults, but relatively few studies have examined the behavior pattern in children.

The purpose of the present investigation was to examine aspects of assessment of the Type A behavior pattern, goal-setting behaviors displayed by Type A and B children, and parents' goal-setting behaviors toward their offspring.

The Distribution And Morphology Of Fucus Distichus In An Estuarine Environment And The Effect Of Selected Ions On The Uptake Of Inorganic Carbon And Nitrate, Dale Howard Robinson

Dissertations and Theses

The morphology, distribution, and habitat of dwarf and normal forms of Fucus distichus in Nehalem Bay were examined. The dwarf form lacked the holdfast and sexual structures of the normal form and was more highly branched. Examples of the dwarf form were found growing as outgrowths of fragmented normal forms indicating that both forms are the same species. The normal form occurred attached to rocks near the mouth of the bay in waters of oceanic salinity. The dwarf form occurred as a free-living form in the salt marshes and in waters of lower salinity. These observations suggested that the occurrence …

Derivation And Test Of Predictions Of A Discrete Latent State Model For Signed Number Addition Test Performance, Kentaro Yamamoto

Dissertations and Theses

This study is an investigation of the performance of a discrete latent state model devised by Paulson (1982) to account for signed-number arithmetic test data gathered by Birenbaum and Tatsuoka (1980). One hundred twenty nine students took a test which consists of sixteen item types with four parallel arithmetic items of each type. The present study utilizes the five addition item types of four items each; hence, there are four parallel subtests. Responses to the addition items can be analyzed in terms of two components: the sign component (is the sign correct?), and the absolute value component (is the size …

Audiological Characteristics Of The Monge Family Of Costa Rica, Christine Moulton

Dissertations and Theses

The audiological characteristics of the Monge family of Costa Rica were investigated in a sample of fifty-two affected members and twelve unaffected members. Through laboratory analysis by staff personnel from the University of Costa Rica and audiological test results obtained in the present investigation, it was concluded that affected Monge members demonstrate a slowly progressive low frequency sensorineural hearing loss of autosomal dominant transmission. The initial site of lesion appears to be the apical portion of the cochlea, with significant onset occurring during early childhood following normal speech and language acquisition. The rate at which the hearing loss progresses and …

Depositional Model Of The Antelope Coal Field, Wyoming, Christine M. Budai

Dissertations and Theses

The coal-bearing sediments of the Antelope coal field in the southcentral Powder River Basin, Wyoming were deposited in paludal and tributary subsystems of the fluvial system that existed in the basin during the early Tertiary. A depositional model for the Antelope coal field was constructed from data collected from approximately 500 drill holes that penetrated the upper 90 meters (300 feet) of the Fort Union Formation. The depositional environments were interpreted from lithologic descriptions and guidelines established in the literature.

The two main coal seams at the Antelope coal field are the Anderson and stratigraphically lower Canyon coal seams. They …

The Expressive Acquisition Of Locative And Directional Prepositions By Severely-To-Profoundly Hearing Impaired Children, Joann Warlick

Dissertations and Theses

Prepositions are important for the syntactical structure of the sentence and also to relate meaning, particularly meaning associated with concepts of place and time. Expressive acquisition of function words, including prepositions, is significantly delayed in the hearing impaired population. Yet, acquisition sequence for expressive prepositions has not been determined for this population.

The purpose of this study was to investigate the oral expressive acquisition of locative and directional single word prepositions in severely-to-profoundly hearing impaired children. The question this study sought to answer was: At what age levels are seventeen locative and directional single word prepositions expressively acquired by severely- …

The German-Oregonians, 1850-1918, Roberta Lee Schmalenberger

Dissertations and Theses

Of all the foreign-born elements of Oregon's population, the German-born have been the most prominent in terms of size and continuity. At the turn of the century they were an organized and enterprising ethnic group that supported a German-language press, numerous social clubs and ethnic churches. The German-born contributed their share to the development of Oregon through men whose names are almost household words today: Meier and Frank, Weinhard, Dammasch, Villard and Weyerhaeuser. Yet for all of their visibility, the Germans in Oregon have not been remembered as a particular ethnic group.

The demise of a visible German culture in …

Development Of An Mmpi Scale To Predict Therapeutic Response To Lithium Carbonate, Neal Allen Hayden

Dissertations and Theses

Common medications utilized in the treatment of psychosis include lithium carbonate and the major tranquilizers. The efficacy of lithium is well established in the treatment of manic-depressive patients exhibiting symptoms of mania. The major tranquilizers treat a broader range of psychotic disorders including schizophrenia.

In the treatment of manic-depressive illness, lithium produces normalization of affect with few side effects. However, since the interval between therapeutic and toxic dosages is narrow, lithium treatment must be closely monitored to avoid severe physical problems and even death. When a schizophrenic is incorrectly diagnosed as manic-depressive, and is treated with lithium, the patient does …

An Internal Review Of A Discipline: Journal Editors' Opinions Of Paradigm Development Within Speech Communication, Laurie A. Houghton

Dissertations and Theses

A review of the literature on paradigm development within academic fields revealed that researchers have drawn distinctions between disciplines with greater paradigm development (discussed as discipline-wide consensus) and disciplines with lesser paradigm development. Several of these investigations centered on paradigm development and evaluative criteria used by academic journal editors for judging scholarly work. The purpose of this study was to ascertain Speech Communication journal editors' opinions of paradigm development within their field.

A two-part survey was developed and mailed to eleven editors of the major Speech Communication journals. Data generated from the survey were analyzed using a descriptive methodology. Part …

A Harmony Of Opposites, Patricia Reppenhagen

Dissertations and Theses

The central concept of my work is to bring opposing visual elements into harmony with one another. I feel that every aspect of life is composed of contradictory components or forces: order vs. chaos, the beautiful vs. the offensive, work vs. leisure, excitement vs. stability, method vs. chance. The examples are endless. These opposing elements are components in life which need to be balanced against each other to achieve harmony and order, as opposed to strife and conflict. Personally, the need for order and control in my own life is important and, I feel, is reflected in the above classical …

The Combined Effect Of Cu And Zn On Selenastrum Capricornutum, Helmer Colonia-Roque

Dissertations and Theses

It has been demonstrated that the toxicity of heavy metals depends on their chemical speciation and can be related to their free ion activities, rather than the total metal concentrations. The objective of this study was to determine the effect of combined free ions of zinc and copper on the toxicity to the green alga Selenastrum capricornutum. This alga was grown in a defined medium, under controlled laboratory conditions, with a varying range of zinc and copper concentrations. The growth rate of the alga was inhibited at pZn = 5.93 or at pCu = 7.24. The results suggest that …

Life Satisfaction Of Elderly Parents And Parent-Child Relationships In Old Age, Tehchou Yeh

Dissertations and Theses

This thesis is designed to explore the nature of the relationship between elderly parents and their children and to investigate the association of that relationship with life satisfaction of the elderly parents. The examination of parents' life satisfaction is based on the activity theory of gerontology. The life satisfaction is measured by Adams's eighteen-item Life Satisfaction Index. The parent-child relationship is viewed from the standpoint of both the parents' expectations of their children and how the children fulfill these expectations. Filial discrepancies between parents' expectations and children's behavior are analyzed to fill a gap in the literature on behavioral and …

Liquid Transmission Line Pulser Circuit For Laser Excitation, Carl Stultz

Dissertations and Theses

The subject of this thesis is the study of liquid dielectric transmission lines and their potential application as an excitation source in high speed, high-repetition rate laser designs. The design problems associated with the construction of high repetition rate (khz), short wavelength lasers have been reviewed and the major shortcomings of conventional electrical driving circuits identified. The identification of these shortcomings and a review of the available literature on electrical circuits for various types of lasers suggested that liquid dielectrics and transmission lines could potentially have significant advantages over more conventional circuitry used in high repetition rate, short wavelength lasers. …

Career Supports And Career Mentors: An Analysis Of Their Prevalence And Their Relation To Career Success And Satisfaction Among A Group Of Women Lawyers, Sandra Lee Riley

Dissertations and Theses

This study investigated three issues problematic to the state of knowledge on mentoring. These issues were: (a) lack of scientifically derived operational definitions in use in research on mentoring; (b) lack of agreement about how common mentoring is; and (c) lack of agreement about whether or not alternate forms of career support are more efficient than mentoring. The information collected to address each of these issues was acquired in two phases: a literature survey followed by a sample survey. The literature survey addressed the first issue. It resulted in the formulation of an operational definition of mentoring which was based …

The Japanese/American Interface: A Crosscultural Study On The Approach To Discourse, Hitomi Tamura

Dissertations and Theses

This study attempted to explore one aspect of the communicative styles of Japanese and Americans: their approach to discourse. In a literature review, four distinctive characteristics were surveyed: linear/nonlinear presentation, inductive/ deductive reasoning, explicit/implicit communication, and analytical/emotional statements. The American style of argument was characterized by:

1) a linear presentation as evidenced by its preference for a sequential paragraph development, its reliance on logic, and its direct introduction of the subject.

2) either inductive or deductive reasoning.

3) explicit communication as shown by its emphasis on the use of concrete language, definite qualifiers, clearly stated conclusions and a wider perspective. …

The Correlation Between Expressive Language Delay In Children And Their Motor Abilities, Gail G. Cunningham

Dissertations and Theses

The purpose of the present study was to determine the correlation between expressive language delay in children and their gross and fine motor skills. Twenty children five years through six years, eleven months with a diagnosed expressive language delay, were selected to participate in the study. Each was screened on the basis of normal hearing, receptive vocabulary skills, motor functioning, and an expressive language delay of one year or more. After screening procedures, each child was administered the Preschool Language Scale-PLS (Zimmerman, et al., 1969) and the short form of the Bruininks-Oseretsky Test of Motor Proficiency-BOMP (Bruininks, 1978). …

Justice Brennan And The Bill Of Rights, David B. Brownhill

Dissertations and Theses

The research problem examined in my thesis is stated clearly in the title: Justice Brennan and The Bill of Rights. In my examination, I relied primarily on Brennan's opinions, and secondarily, on scholarly commentaries authored by Brennan and others. I located the cases through a combination of sources. Initially, I consulted the Harvard Law Reviews' "Supreme Court Term, (1956-1981) Term(s)," which is published annually in its November edition, and then, I turned to the writings by, and about, Brennan my findings show that Brennan's approach in these cases has evolved over the years toward a more absolutist one.

The Effects Of Various Chemical Treatments On The Surface Area Of Coals, Maria Margaret Ludvig

Dissertations and Theses

Surface areas of most American coals are small when measured by N₂ adsorption at 77 K and large when measured by CO₂ adsorption at 298 K, implying that the majority of the pores are less than 5 Å in diameter. This small pore size would restrict many gaseous and liquid reactants from entering the internal pore system of the coal, and hence, reduces the efficiency of coal conversion. Therefore, if the surface area, as measured by N₂ (77 K), could be increased, that is, to increase the pore size, the conversion of coal into useful products should …

Holocene Geologic History Of The Clatsop Plains Foredune Ridge Complex, David Karl Rankin

Dissertations and Theses

Effect Of Tinnitus Maskers On Speech Discrimination Among Those Wearing Tinnitus Maskers, John Alexander Chonka

Dissertations and Theses

The purpose of this study was to determine the effect(s) of tinnitus maskers and tinnitus instruments on speech discrimination utilizing a population of subjects who currently have tinnitus and are presently wearing these devices. The hypothesis which guided this investigation states that there is no difference between discrimination scores with and without tinnitus maskers. In an attempt to test this hypothesis, speech discrimination scores were obtained from 26 listeners both in quiet and in the presence of cafeteria noise, with and without use of their tinnitus maskers.

The Introduction Of European And Asian Cultural Materials On The Alaskan And Northwest Coasts Before 1800, Herbert Kyle Beals

Dissertations and Theses

This thesis concerns the introduction of exogenous cultural materials among the native inhabitants of the Alaskan and Northwest coasts prior to the and of the 18th century. It is an investigation of the sources of these materials and the manner and chronology of their introduction. The research is based primarily on data drawn from accounts of native life by explorers and fur traders who visited the coasts of northwestern North America in the 18th century. These accounts are supplemented by ethnologic and archaeologic data collected by anthropologists in the 19th and 20th centuries.

Analytical And Experimental Stresses In Concrete Pavements And Unbonded Overlays, Ahmad Jaber

Dissertations and Theses

The principal objective of this study is to determine the accuracy of calculating stresses in concrete pavements and unbonded overlays under different loading conditions. The computed stresses for the single layer pavements are obtained based on Westergaard theory, the finite-element model (ILLI-SLAB), and the elastic layered model (ELSYM5). For the two-layer unbonded systems, stresses are estimated based on the finite-element theory and the Portland Cement Association design method. The experimental results for the comparison were available from a series of tests done on model scale concrete pavements and unbonded overlays. The results of present investigation show that the computed stresses …

Breeding Success And Nest Site Characteristics Of The Western Bluebird On Parrett Mountain, Marcia Diane Sims

Dissertations and Theses

The lack of suitable nest sites may be a limiting factor for Western Bluebird populations inhabiting the upper Willamette Valley. Nest box trails have been established on the hills surrounding the Portland metropolitan area. Since their placement, approximately 25% of the boxes available have been used by Western Bluebirds as nest cavities. This study was undertaken to identify factors which might determine the selection of a nest box by Western Bluebirds and the subsequent nest success or failure.

The breeding biology of Western Bluebirds using the nest box trail located on Parrett Mountain, Oregon in 1979 was investigated. Breeding season, …
