Lewis And Clark At Fort Clatsop: A Winter Of Environmental Discomfort And Cultural Misunderstandings, Kirk Alan Garrison

Dissertations and Theses

Members of the Lewis and Clark expedition did not like the 1805-1806 winter they spent at Fort Clatsop near the mouth of the Columbia River among the Lower Chinookan Indians, for two reasons. First, the environment west of the Rocky Mountains was unlike anything they had ever experienced or imagined, and it had such a powerful effect on the whites as to negatively influence their attitudes regarding the western landscape, and to prejudice the explorers against the peoples living in that environment.

Second, the cultures of the Lower Chinook Indians and the whites were so different that often neither group …

Hiroshima Mon Amour And L'Annee Derniere A Marienbad: Meaning Conveyed Through Cinematic Organization, Ellen Leigh Agee

Dissertations and Theses

This thesis examines how the cinematic organization of film is used to convey meaning. Hiroshima mon amour (1959) and L'Année dernière à Marienbad (1961), two films directed by Alain Resnais, are used as models for this purpose. This thesis argues for a new type of film criticism, one that recognizes the uniqueness of film by adding technical analysis to the literary methods that currently dominate.

Traditionally, film criticism has followed two directions: firstly that of the "film reviewer" whose efforts bow to the economic needs of the industry, and secondly the academic or scholarly approach which is based in large …

The Role Of The Hepatic Vagus In The Pathogenesis Of Fever, Christopher Todd Simons

Dissertations and Theses

Recent evidence has suggested a role of vagal afferents in the pathogenesis of fever. Although bilateral truncal subdiaphragmatic vagotomy has been shown to attenuate the febrile response to lipopolysaccharide (LPS) and interleukin-1, no study has yet been able to verify which of the five subdiaphragmatic vagal branches (viz., the anterior and posterior celiac branches, the anterior and posterior gastric branches, and the hepatic branch) is responsible for communicating this signal. The present study tested the hypothesis that the hepatic vagal branch mediates pyrogenic signals from the periphery to the brain. Male Wistar rats underwent one of four selective …

Real Ear To Coupler Differences In Children And The Effects Of Hearing And Microphone Location, Cindy Richardson

Dissertations and Theses

The early identification of hearing loss and selection of appropriate amplification are the most important goals for children with hearing impairment. Selection of appropriate amplification for a pediatric population involves maximizing the hearing impaired child's residual hearing, for development of speech and language. In addition, it is important to consider the acoustic differences between the 2 cc coupler versus the real ear.

During the hearing aid selection process, it is customary to predict how a hearing aid will respond in the real ear, based upon a given 2 cc coupler response. Killion and Monser (1980) developed a formula for converting …

Grandmothers Laughing: Intergenerational Transmission Of Cultural Beliefs About Pregnancy And Childbirth Among Native American Women, Claudia Robin Long

Dissertations and Theses

This dissertation reports findings from a qualitative study of intergenerational transmission of pregnancy and childbirth information among Native American women. Proposed is a theory of intergenerational transmission that explains four pathways used by Indian women to gain information about pregnancy and childbirth. Antecedent, consequent, and core elements are associated with the transmission process.

Discriminant sampling was used to identify the middle generation of Indian mothers and grandmothers, between 36 and 65 years of age, residing on or near the reservation, with experience of assimilation policies that had moved off-reservation temporarily. The researcher used the grounded theory method to analyze responses …

Wedding Bands And Marriage Bans: A History Of Oregon's Racial Intermarriage Statutes And The Impact On Indian Interracial Nuptials, Matthew Aeldun Charles Smith

Dissertations and Theses

Beginning in the late eighteenth century, the first contacts between white and Indian cultures in Oregon quickly secured marriages between the European and American traders and trappers and indigenous women. These unions sustained economic alliances and nurtured cultural links.

But the opening of the Oregon Trail brought an influx of white men and women from America's Middle West who stored more than supplies in their wagons. They transported racial beliefs which subjugated all non-whites to an inferior status. Laws were passed by this generation of pioneers in each governmental period -- provisional, territorial and statehood -- which codified a wide …

High-Performance Input/Output Circuit For Cmos Integrated Circuit Interface, Chee How Lim

Dissertations and Theses

In recent years, strong demand for high-performance electronic products has fueled the need for high-speed and high-integration VLSI circuits. This demand is expected to continue growing in the future, which will lead to development of IC's that are much more compact and operate at higher frequencies. As a result, preserving signal integrity for proper IC communications becomes an increasingly difficult challenge.

In this thesis, an understanding of IC noise in relation to IC packaging is sought. An IC package is modeled with sophisticated 3-D simulators to extract its corresponding parasitics. These parasitics, expressed in terms of resistance, inductance, and capacitance …

Collective Intervention In Internal Conflicts: An Examination Of Why States Participate, Andrew L. Blum

Dissertations and Theses

There is a longstanding debate in the international relations discipline over the relative influence of self-interest and norms on the behavior of states. This study will seek to contribute to this debate by investigating what motivates states to engage in a specific type of behavior, which I will call collective intervention. The multinational operations, which have attempted to resolve internal conflict in places like the Congo, Lebanon, El Salvador, Cambodia, Somalia and Bosnia, are the result of this behavior. Dozens of states, of diverse economic standing, military capability, geographic region, and political ideology have participated in these operations. This study …

Limitations Of Methods For Determining The Position Of The Center Of Mass Of A Human Subject Performing A Sit-Up, Terrence Chadwick Smith

Dissertations and Theses

The knowledge of the position of the center of mass of a human subject performing a sit-up could help us understand the coordination of the sit-up motion. This thesis investigates the limits in three methods of determining the center of mass of a human subject. The three methods are the anthropometric method, the dynamic method, and the static torque method. The anthropometric method is a standard method that uses measurements of the subject to estimate the mass properties of individual segments of the body. The center of mass of the body is calculated from the mass and positions of the …

The Minimal Role Of Legal Traditions At The International Court Of Justice, Kalley Rae Aman

Dissertations and Theses

International legal scholars and lawyers have dedicated much thought and energy to enhancing their understanding of how judges at the International Court of Justice (ICJ) come to decide cases the way they do. Although these studies of judicial behavior at the ICJ have provided insight into international judicial decision-making, still little is known about how international judges reach decisions. This project was an attempt to improve upon the explanations, given thus far, for the decisions made by ICJ judges in the cases brought before the Court. In this study I tried to ascertain whether and to what extent the legal …

The Language Of Transformation In A "Conversation For Possibility": A Metaphor Analysis, Deborah Jean Gabbert

Dissertations and Theses

Metaphor allows us to understand and experience "relatively abstract or unstructured subject matter in terms of more concrete, or at least more highly structured subject matter". Lakoff and Johnson's (1980) and Lakoff's (1993) contemporary theory of metaphor contends that: metaphor is fundamentally conceptual; metaphoric structuring is the basis for the organization and functioning of much of the ordinary human conceptual system; and metaphorical language found in everyday speech is a surface manifestation of underlying conceptual metaphors. The metaphors most salient in a culture's discourse will reveal something about what is thinkable, knowable, and doable in that culture. Metaphors have the …

Achieving Cochannel Interference Objectives Over Selected Topologies In The Portland Oregon Cellular Network, David A. Wand

Dissertations and Theses

Wireless cellular mobile communications is a rapidly growing global technology which places increasing demands on a limited electromagnetic radio frequency spectrum. However, in North America only a 25 MHz block of spectrum has been allocated to each of two service providers. This must be utilized for all services offered within their assigned market.

The wireless cellular link from the mobile or portable phone to terrestrial base stations utilize this limited frequency spectrum. This is divided into 416 two-way channels, each 30 kHz in width, a subset of which is assigned to each base station. As more base stations are constructed, …

Erp Analysis Using Matched Filtering, Correlation Coefficient And Mann-Whitney Test, Yun Yan

Dissertations and Theses

Event related potentials (ERPs) carry very important information that relate to the performance of the brain functions of a human being. Further studies have identified that the late positive complex (LPC) are affected by the memory process.

The matched filter method is used to improve the signal-to-noise ratio of signal ERPs. We use the output of the matched filter to distinguish the difference of the waveforms. In our study, we found that the peak values of the matched filter output differed among normal subjects and memory-impaired subjects.

The correlation coefficient is a statistical value that can be applied to find …

This study draws on a sample of 50 Korean-American elders in subsidized housing who are over the age of sixty and live in the Portland, Oregon Metropolitan area to investigate factors involved in their choice of and their well-being in independent living arrangements. Through interviews, the study specifically gives attention to why the elders moved, whether they …

Preternatural Rhythm: A Vernacular Application Of The Systemic Grid With Respect To The Influence Of Organic Processes, Mark Richardson Smith

Dissertations and Theses

The practice of Systemic Art was first introduced under the pretext of Minimal/Conceptual art processes in the 1960s, which incorporated the presentation of empty gridded armatures and self-referential charts, (termed non-relational arrangement) as a means of democratizing esthetic content. Systemic objects stressed industrial fabrication and materials m their manufacture over traditional notions of individualized craft, with the intent to demystify the role of the artist in the creative process. For those reasons, systemic practice has remained highly influential among artists concerned with the public context of aesthetics, although its recent applications have gravitated towards incorporation of disparate materials and …

Predictions Of Intentions Of College Students To Take An Hiv Antibody Test And Their Preferences For A Testing Procedure, Hitoshi Ishimaru

Dissertations and Theses

Intentions to prevent HIV infections are an essential part of HIV prevention. Social science researchers and HIV educators have investigated the roles of intentions to prevent HIV infections mainly in the context of safer sex behaviors. Surprisingly, however, HIV testing intentions have not been extensively studied in light of various forms of HIV tests that are likely soon to be approved for widespread use . The present study evaluated the utility of Ajzen and Fishbein' s (1980) Theory of Reasoned Action in predicting college students' intentions to take an HIV test. Attitudes toward HIV testing and their perceptions of social …

A Comparison Of Parent Interview And Direct Assessment Of Receptive Language In Preschool-Aged Children With Cerebral Palsy, Susan Kathleen Livick

Dissertations and Theses

Cerebral palsy is a multiply handicapping condition which may affect motor skills, hearing, sight, speech and cognitive functioning. Assessment instruments which do not rely on an intact sensory and motor system are needed for use with the population with cerebral palsy in order to obtain valid information regarding levels of functioning. The information obtained from the results of modified assessment instruments can be used to plan and implement intervention at the child's current level of functioning.

The purpose of the present study was to determine whether or not parent interview/report is a reliable means of assessing receptive communication skills in …

Human Trampling In The Upper Rocky Intertidal: Trampling And Recovery In Barnacle Mediated Succession, Timothy Lawrence Grubba

Dissertations and Theses

Marine intertidal ecosystems are vulnerable to human interference, because trampling can be a significant problem. I studied the impacts of trampling on community patterns and succession in a rocky intertidal habitats. This study was divided into two phases: (1) a trampling phase and (2) a recovery phase. Both phases are focused on two barnacles, Balanus glandula and Chthamalus dalli, and on fucoid and red algae. The trampling phase tested the effects of trampling on these organisms. The effects of herbivores, primarily limpets (Collisella digitalis) were also tested to determine whether anthropogenic (trampling) and natural (herbivory and limpet …

The Column Multiplicity Problem In Decomposition Of Functions And Relations, Rahul Malvi

Finding the column multiplicity in Functional Decomposition has been known to be one of the most important problems to be solved in the process of functional decomposition of discrete functions. A lot of research has been done in this field with many new heuristics generated to find the column multiplicity, but there has not been an evaluation of the algorithms on the kinds of graphs that occur in decomposition and whether having an exact method to calculate the column multiplicity is useful from the overall design goals.The intent of this thesis was to investigate the column multiplicity problem, in order …

Pregnancy Outcomes: A Study Testing A Model For Predicting Health Outcomes In Pregnancy, Tamera Ann Hart-Johnson

Dissertations and Theses

There is a persistent relationship between socioeconomic status and physical health outcomes found in the literature; however the variables mediating this relationship are many, and ways that they interact with each other are complex. The goal of understanding this relationship is to decrease the disparity in health by socioeconomic status.

This study tested a biopsychosocial model proposed by David Williams (1990) to explain the relationship between socioeconomic status and physical health outcomes. The model included the following latent factors: demographics, socioeconomic status, biomedical risk, medical care, psychosocial variables, and health outcomes. The model was tested through a secondary data analysis. …

Gross Estimation: A Study Of The Clinical Validity For Measuring Intelligibility, Heather Gail Clarke

Dissertations and Theses

Intelligibility is the most fundamental factor for successful speech communication. Measurements of speech intelligibility carry important clinical consequences that relate to description of severity, need for intervention, intervention goals, service delivery options, and treatment efficacy. It is important, therefore, that speech-language pathologists use an approach that reflects an accurate and valid measure of intelligibility. The purpose of this study was to investigate the relationship between the two seemingly most common procedures used by practicing speech-language pathologists for measuring speech intelligibility: the gross estimation of intelligibility procedure, and the orthographic transcription procedure. Twelve 100-word connected speech samples were analyzed by 4 …
