Distribution Coefficients Of Ionized And Un-Ionized Halogenated Phenols In An Octanol-Water System And Their Relationship To Molecular Structure, Sven Hensler

Dissertations and Theses

Life supporting biological membranes are barriers to toxic chemicals. One of the factors determining the toxicity of chemical compounds is their distribution between membranes and their an environment. An octanol-water system is frequently used as a model for biological membranes to estimate the toxic potency of environmental pollutants. The distribution of a chemical between the octanol and the water phase is described by the octanol-water partition coefficient K_OW. This study is concerned with the relationship between K_OW and the molecular structure of the toxic chemical.

In the study the following trihalophenols were included: 2,4,6-trifluorophenol (TriFP), 2,4,6-trichlorophenol (TriCP); …

Willa Cather's Spirituality, Mary Ellen Scofield

Dissertations and Theses

Both overtly and subtly, the early twentieth century American author Willa Cather (1873-1947) gives her readers a sense of a spiritual realm in the world of her novels. '!'his study explores Cather's changing conceptions of spirituality and ways_in which she portrays them in three of her novels. I propose that though Cather is seldom considered a modernist, her interest in spirituality parallels Virginia Woolf's interest in moments of heightened consciousness, and that she invented ways to express ineffable connections with a spiritual dimension of life. In 0 Pioneers! (1913), Cather proposes that those who use their intuition to express themselves …

Neorealism And Environmental Cooperation: Towards A Structural Explanation Of International Environmental Matters, Anthony David Lott

Dissertations and Theses

The realist tradition in world politics has long been heralded by statesmen and scholars alike as offering an authentic account of the relations between states. Realists consider self-interest, anarchy, and power politics to guide the behavior of states in the international system. The perception that cooperation and amity are now the norm in the international system has raised the possibility of a theoretical shift of focus in the study of international politics. At present, scholars within the discipline of international politics are debating the relevance of realist thought. In particular, neorealism, or the structural variation of traditional realism, is under …

Ottilie: Expression Of The Ideal Of Romantic Childlikeness In Goethe's Wahlverwandtschaften, Melodie Joy Steele

Dissertations and Theses

The interpretation of Ottilie in Goethe's Wahlverwandtschaften stems from an understanding of romantic motifs, which find their most systematic expression in her childlike character. Ottilie embodies the romantic idealization of childhood as a means of withdrawal from the enlightened world, echoing the Romantics' rejection of the disenchanted Age of Enlightenment. Through her portrayal of innocent childlikeness, her adolescent conflict with the rational world, and her final rejection of enlightenment, Ottilie maintains her childlike purity, expressing the romantic ideal of childhood.

Ottilie's childlike emotional disposition puts her in conflict with the enlightened world of adults and academia. In an attempt to …

The Dangers Of Nuclear Proliferation: Five Reasons More May Not Be Better, Matthew Macarthur

Dissertations and Theses

Though many international relations theorists have speculated that the spread of nuclear weapons may diminish the frequency -- if not the severity -- of military conflict among states, there are five reasons to expect that increased proliferation will increase the likelihood that nuclear weapons will be employed for coercive or destructive purposes. These dangers are independent of one another; that is, they are not interconnected as causes and effects. First, as nuclear weapons spread, the notion that these weapons are useful for purposes other than deterrence will spread concomitantly. Those who argue that the spread of nuclear weapons will diminish …

The Socio-Cultural Content Analysis Of English As A Foreign Language Textbooks Used In Junior High School In Taiwan, Republic Of China, Vivian Yann-Ling Lu

Dissertations and Theses

The English textbooks evaluated are used to prepare students for the competitive high school entrance examinations in Taiwan, thus students spend a great deal of time studying them. Though the textbooks were stated to be designed for language and cultural learning purposes, it seems no study exists that examines to what degree there is clear articulation between the government's stated culture learning goal and actual textbook content. Therefore, this study examines to what degree the textbooks allow students to reach said goal, that is, "to increase culture awareness of the societies and cultures of foreign countries and our own" (Junior …

Speech Understanding In Noise As A Function Of Microphone Placement In Hearing Aids, Erin Marlene Flowers Hand

Dissertations and Theses

Hearing aid users often complain of poor speech understanding in the presence of background noise. There have been many attempts to overcome this problem by hearing aid manufactures and dispensers. The purpose of the present study was to determine if differences existed between three different styles of hearing aids (i.e. in the ear (ITE), in the canal (ITC), and completely in the canal (CIC)) in the presence of a multi-talker babble. Five sensori-neural hearing impaired subjects were selected from the Portland State University audiology clinic. The subjects were required to listen to a recording of the California Consonant Test (CCT) …

Speech Recognition With Linear And Non-Linear Amplification In The Presence Of Industrial Noise, Marcia Ann Olson

Dissertations and Theses

In order to help reduce hearing loss, the Occupational Safety and Health Administration regulates noise levels in work environments. However, hearing aids are the primary rehabilitative service provided for individuals with an occupational hearing loss. Very little is being done to monitor hearing aid use in the work environment. Noise which may be safe to an unaided ear can amplified to levels that are damaging to the ear when a hearing aid is being worn. However, it is necessary for some individuals to wear amplification in these noisy environments for safety reasons. As a consequence it is important that these …

The Flor Metaphor Of Pre-Conquest Nahuatl Literature, Victoria Louise Defferding

Dissertations and Theses

The purpose of the present study is to show that the metaphor, flor, of Pre-Conquest Nahuatl literature means much more than the most widely accepted rendering of that metaphor that classic scholars such as Miguel Leon-Portilla and Angel M. Garibay have attributed to it. Typically flor is referred to as meaning poetry. It is explored in this study as a metaphor that refers to entheogenic plants, their use and the divine words or songs, or poetry, that resulted from their use. As evidence for the theory presented, I examine and discuss various religious practices and important archeological treasures in …

An Analysis Of The Literary Manifestations Of The Cult Of The Virgin Mary In Gonzalo De Berceo's Milagros De Nuestra Senora, Elizabeth M. Deeter

Dissertations and Theses

The cult of the Virgin Mary reached its climactic point in Europe during the Middle Ages, and was particularly strong in Spain. Literature became a concrete expression of Marianism because it reflected the beliefs of the populace. Gonzalo de Berceo, a Castilian monk, greatly influenced by the ever-growing Marian piety, wrote a collection of poems in which the activity of the Blessed Mother in everyday human life is documented. I propose to do a detailed miracle-by-miracle analysis of Mary's interactions with others by focusing on Berceo's characterization of her in her principal role as a mother. In addition, I will …

The Industrial Workers Of The World And The Oregon Packing Company Strike Of July 1913, Adam J. Hodges

Dissertations and Theses

This study builds upon the notion of a Wobbly 'sensibility' established by Salvatore Salemo and relates it to John Townsend's analysis of conflict between that group's adherents and western Progressives. The latter scholar, by concentrating on middle-class economic anxiety, failed to deal with the virtual unanimity of opposition to the IWW in western towns. Salerno's assertion that a 'sensibility' within the IWW was more binding than ideology raises the possibility that individuals and organizations of varying beliefs could be similarly united within a single cultural sphere with a directed purpose. Such an analysis can apply to factions of Progressivism and …

The Role And Perception Of Risk In High-Risk Sports Participants: A Grounded Theory Study Of Rock Climbers, Ronald E. Baglien

Dissertations and Theses

Previous research examining high-risk sports participation has yielded discrepancies between the role assigned to risk and the perceptions of climbers regarding risk. Risk, as it applies to high-risk sport participation, has not been sufficiently defined in the literature. The current study sought to develop, by means of a grounded theory approach, a new, dynamic operational definition of risk as it applies to rock climbers, and to examine the role of risk management as a modifying factor in the perception of risk and its impact on motivation and participation. Nineteen subjects (twelve male and seven female) averaging 14.7 years of climbing …

Comparison Of Two Phonological Treatment Procedures For A Child With Phonological Deviations, Katherine Vaughan Kemper

Dissertations and Theses

Choosing an effective and efficient phonological treatment approach is an important decision for clinicians when treating children with phonological deviations. Current research supports the effectiveness of phonological treatment, but few studies have compared two approaches. More comparative studies are essential to support clinical intervention for children who are highly unintelligible.

This single-subject study was designed to compare the effectiveness of two phonologically-based treatment approaches in facilitating an intelligible speech production system for one highly unintelligible preschool female. Multiple baselines across behaviors with an alternating treatment design were used in this descriptive study. This study sought to answer the following questions: …

Investigating Vowel Duration As A Perceptual Cue To Voicing In The English Of Native Spanish Speakers, Becky Jean George

Dissertations and Theses

Researchers in the cognitive sciences, and in particular those in acoustic phonetics, investigate the acoustic properties in the speech signal that enable listeners to perceive particular speech sounds. Temporal cues have been found to convey information about the linguistic content of an utterance. One acoustic characteristic that is particularly well documented in American English is the difference in vowel duration preceding voiced and voiceless consonants, which has been found to play a role in the perception of the voicing of postvocalic word-final consonants. Research on vowel duration and its role in the perception of the voicing distinction of the following …

Correlation Of The Upper Ellensburg Formation With The Old Scab Mountain Eruptive Center, East-Central Cascade Range, Washington, Christopher Charles Humphrey

Dissertations and Theses

The Ellensburg Formation, preserved in the Nile basin 50 km northwest of Yakima, Washington, consists of a series of middle to late Miocene epiclastic and pyroclastic rock assemblages rich in porphyritic hornblende-biotite dacite. Geochemical, petrographic, and stratigraphic correlations indicate that Old Scab Mountain, a dacite porphyry intrusion, located at the western margin of the basin (lat. 46°53'30", long. 121°13'00"), is the probable source for much of the upper Ellensburg volcaniclastic material in the basin. The dacite intrusion exposed at Old Scab Mountain was emplaced at depths of 1 to 3 km and underlaid a now eroded volcanic edifice. This volcanic …

Adolescents And Sex On The Soaps: A Content Analysis, Jenelle Gay Winter

Dissertations and Theses

This study updates prior examinations of sexual content on daytime soap operas by investigating verbal references, implied sexual acts and mentions of sexually transmitted diseases. In addition, it extends earlier work by analyzing the commitment level and age of those involved in the sexual content. Finally, this study will attempt to obtain a clear picture of what adolescents perceive while viewing these shows. This was investigated by conducting adolescent and adult focus groups to see how they talk about soap operas. Also, comparisons were made of adult and adolescent coding of the sexual content on soap operas. All daytime soap …

Beach Response To Subsidence Following A Cascadia Subduction Zone Earthquake Along The Washington-Oregon Coast, Debra Lee Doyle

Dissertations and Theses

Beach shoreline retreat induced by coseismic subsidence in the Cascadia subduction zone is an important post-earthquake hazard. Sand on a beach acts as a buffer to wave attack, protecting dunes, bluffs and terraces. The loss of sand from a beach could promote critical erosion of the shoreline. This study was initiated in order to estimate the potential amount of post subsidence shoreline retreat on a regional scale in the Central Cascadia Margin. The study area is a 331 km stretch of coastline from Copalis, Washington to Florence, Oregon. Several erosion models were evaluated, and the Bruun model was selected as …

Correction Of Classroom Oral Errors: Preferences Among University Students Of English In Japan, Akemi Katayama

Dissertations and Theses

Correction of oral errors in foreign or second language classrooms has been an issue of great concern. Although the literature on error correction is abundant, the studies on student reaction to this pedagogical practice are few.

This study investigated the preferences for correction of classroom oral errors among university students of English in Japan. Data were collected from anonymous questionnaires. The study examined the students' attitudes toward the views about correction of oral errors which have been controversial among foreign and second language educators. The study also investigated the students' preferences for correction of different types of oral errors (e.g., …

An Evaluation Of English Spoken Fluency Of Thai Graduate Students In The United States, Sugunya Ruangjaroon

Dissertations and Theses

Fluency is generally recognized as speaking with a high rate of speech. This study provides a greater understanding of the notion of fluency that speech rate is not the only measure to determine the fluency level of a speaker. Particularly in a second language (L2), fluency involves other features and it can reflect non-native speakers' capacity in using L2. Fluency is comprised of the continuity and the smoothness of speech without a high occurrence of hesitation phenomena and repair mechanisms.

The purpose of the present study was to analyze English spoken fluency of Thai graduate students. This study sought to …

Bertolt Brechts Exilleben Und Parallelen Zur Entstehung Des Werkes Leben Des Galilei, John Timothy Mangan

Dissertations and Theses

When Bertolt Brecht flees Nazi Germany in 1933 he spends fourteen years in exile where he writes some of his most significant works, among them, Leben des Galilei. In his Leben des Galilei, Brecht explores the relationship between the individual and society. Using the historical Galileo Galilei as context, Brecht elucidates the responsibility that scientists must accept for how their discoveries are put to use. With his Galilei figur, Brecht expresses his belief that scientific advancement should be employed for the societal advancement of the common person. Brecht wrote three versions of his Galilei work, each showing significant …

Needed Narrowing As The Computational Strategy Of Evaluable Functions In An Extension Of Goedel, Bobbi J. Barry

Dissertations and Theses

A programming language that combines the best aspects of both the functional and logic paradigms with a complete evaluation strategy has been a goal of a Portland State University project team for the last several years. I present the third in a series of modifications to the compiler of the logic programming language Goedel which reaches this goal. This enhancement of Goedel's compiler translates user-defined functions in the form of rewrite rules into code that performs evaluation of these functions by the strategy of needed narrowing. In addition, Goedel's mechanism that evaluates predicates is supplemented so that needed narrowing is …

Seed Pods, Bases And Formalism: An Artist's Journey, Craig Luster

Dissertations and Theses

A sculpture can offer visual information that is simple or complex. The work can present only a single facet to ponder or deal with all facets equally polished and linked. There can be enough information to arrange in an order that reads as narrative. All is possible but, without question, the more complex the sculpture, the more information given, the greater the challenge to the artist to make a coherent and interesting whole of everything being presented. The body of work presented in my thesis show represents the outcome of exploring a chain of questions about sculpture. The first question …

Examining The Relationship Between Three Speech Features And Intelligibility Ratings Of Black English Preschoolers As Judged By Standard English Listeners, Britteny Sue Asher

Dissertations and Theses

Linguistic diversification within our public schools has demanded professional responsibility from speech-language pathologists (SLPs) serving nonstandard English speaking students. Understanding and recognizing normal cultural linguistic differences is the responsibility of the SLP. This study focused on the relationship of three speech features to intelligibility ratings of 10 preschool aged Black English speakers as assigned by 4 licensed standard English speaking SLPs with varying experience. The SLPs also rated the perceived effect of these speech features (i.e., articulation, speaking rate, and resonance) on intelligibility.

Using the Pearson product-moment correlation, ratings were correlated and found to demonstrate an association between intelligibility ratings …

A Study Of The Correlation Between The Articulation Competence Index (Aci) And The Percentage Of Words Understood In The Continuous Speech Of 4- And 5-Year-Olds Of Varying Phonological Competence, Susan Coll Mitchell

Dissertations and Theses

Intelligibility refers to how recognizable a speaker's words are to the listener. Severity, a broader but closely related concept, incorporates intelligibility, disability, and handicap. Many factors influence intelligibility, including speech sound production, voice, and prosody, as well as a number of linguistic and contextual factors. Clinicians and researchers in the field of speechlanguage pathology require accurate measures of intelligibility and severity to assess and describe communicative functioning and to measure change over time. Determining the most accurate and efficient measurement approaches has been the focus of recent attention in the field. This study was a preliminary investigation of the relationship …

An Organizational Profile: Members' Understanding Of Discrimination, Debra Cay Hornibrook

Dissertations and Theses

Cultural diversity in the United States is an issue of concern and organizations must now learn to function effectively with an increasingly diverse workforce. Since the history of U.S. organizations is a history of institutional discrimination against most ethnic and racial groups of people and the privileging of a dominant group, managing workforce diversity now constitutes one of the most difficult and important issues human resource professionals address. This study is concerned with the issues of workforce diversity, most specifically with how organizational members understand and respond to discrimination, and the utilization of this understanding to discuss implications for diversity …

Gender Differences In The Language Development Of Late-Talking Toddlers At Age 3, Nancy Ann Johnson

Dissertations and Theses

Language is a major part of a child's early developmental growth. Research examining early language shows a wide variation in the rate of language acquisition and its pattern of development. These variations also exist when language development is delayed.

The purpose of this study was to investigate the possibility of a relationship between gender and language delay by looking for significant differences in the language skills of 3-year-old boys and girls who were identified as late-talkers (LTs) at the age of 2.

Data used for analysis in this study were retrieved from data collected earlier as part of the Portland …

Parental Perceptions Of The Efficacy Of Clinical Intervention For Speech-Language Disorders At Portland State University's Speech And Language Clinic, Deborah Ellen Anderson

Dissertations and Theses

The purpose of this study was to investigate the survey as a method of assessing client satisfaction with clinical services and to then assess parental satisfaction of clinical services at Portland State University's language clinic using the survey method. The survey asked questions regarding the parents' perceived benefits from the clinic, their perception of the skills of the clinicians who served their children, and the parents' perception of the clinical atmosphere.
