The Contribution Of The Lymph Hearts In Compensation For Acute Hypovolemic Stress In The Toad Bufo Marinus, Mark Baustian

Dissertations and Theses

Currently published data on the role of the lymphatic system in amphibians are inadequate and contradictory. Estimates of the rate of formation of lymph and the role of the lymph hearts in returning this fluid to the circulation are not based on actual volume determinations but rather estimates derived from changes in hematocrit using published values of plasma and blood volume. The lymph hearts are known to be vital to the maintenance of normal fluid compartment physiology and to increase their rate of activity during episodes of hypovolemic stress. Yet, significant redistribution of body fluids following hemorrage appears to occur …

The Effects Of Maternal Support And Non-Support On The Family Concepts Of Sexually Abused Girls, Sharon R. Hitchens

Dissertations and Theses

Incest, and the problems arising from it, have increasingly come under the scrutiny of therapists and researchers. All family members are affected by incest and all have been studied. Victims are particularly devastated by sexual abuse by a family member but it is a commonly held belief that having a supportive mother can mitigate the trauma a victim experiences. In this study, girls between the ages of ten and eighteen who were the victims of sexual abuse by a father-figure were compared to a group of girls not thought to be incest victims. The incest victims were divided into two …

Cultural Characteristics Of Learning And Perceptual Skills Of Southeast Alaskan Native 5-Year-Olds, Thomas J. Turkon

Dissertations and Theses

This study examined the use of cognitive skills by 5-year-old Alaskan Native children on a standardized testing instrument. The Wechsler Preschool and Primary Scales of Intelligence (WPPSI) were administered to 23 boys and 17 girls of predominantly Tlingit, Tsimshean, and Haida ancestry. A standardized parent interview was used to collect bio-demographic data. Mean scores for the sample displayed significant differences between the Performance and Verbal scales, with the strongest performance in the Spatial subtests, and lowest in the Sequential subtests. Scores were significantly associated with variables representing culture-specific self identity and behavior, but were most strongly associated with family size. …

The Effects Of Income Inequality On Racial Residential Segregation In The Portland Metropolitan Area, Katayoun Aidinezhad

Dissertations and Theses

Changes in the patterns of income and residential segregation were examined in the Portland Metropolitan Area. The 1970 and 1980 Census of Population and Housing were used in calculating the indexes of dissimilarity between black and white populations. The data indicated a significant decrease in the residential segregation of blacks in suburban areas between 1970 and 1980. The central city area still remained highly segregated with a segregation index of 69.5.

Taeuber's index of dissimilarity was used in calculating the unevenness in the distribution of income between blacks and whites. Suburbia showed a significant decrease in income segregation compared to …

The Geology, Geochemistry, And Alteration Of Red Butte, Oregon: A Precious Metal-Bearing Paleo Hot Spring System, Carol Susan Evans

Dissertations and Theses

Red Butte is located 60 km south of Vale, Oregon, about 20 km west of the Oregon/Idaho border. The butte is within the Owyhee Upland physiographic province of eastern Oregon which lies at the intersection of the Western Snake River Plain, the High Lava Plains, and the Northern Basin and Range provinces.

The butte is composed of Miocene to Pliocene lacustrine and fluvial volcaniclastic sediments. The topography of the butte is controlled by silicification of the sandstones and mudstones which cap it. Silicification and hydrothermal alteration are both structurally and stratigraphically controlled. North-trending normal faults dominate the area, and show …

A Comparative Study Of The Developmental Sentence Scoring Normative Data Obtained In Portland, Oregon, And The Midwest, For Children Between The Ages Of 5.0 And 5.11 Years, Eileen Mcnutt

Dissertations and Theses

The focus of this study was the Developmental Sentence Scoring (DSS), developed by Lee and Canter (1971) and Lee (1974). The DSS is used to analyze a corpus of 50 utterances according to eight grammatical categories. Once a DSS score is determined for an individual child, that child's performance can be compared to that of his/ her peers, using the normative data provided by Lee (1974), and reported by Koenigsknecht (1974). This normative data has been widely used both clinically, and in research projects with little regard for the validity of the norms when applied outside the Midwest, where it …

The Influence Of Situational Cues On A Standardized Speechreading Test, Maria Navarro Montserrat

Dissertations and Theses

Aural rehabilitation programs recommend the use of situational cues by hearing-impaired individuals to facilitate understanding in everyday communication. Although this practice is generally accepted, little is known about the use of situational clues as an adjunct to speechreading performance.

The purpose of the present study was to determine the influence of situational cues on a standardized speechreading test in order to assess an individual's natural speechreading ability. The widely used, standardized Utley Lipreading Test was selected to which photoslides of message-related situational cues were added. The Utley Lipreading Test consists of two relatively equivalent test lists, containing series of unrelated …

A Comparative Study Of The Northwestern Syntax Screening Test Data, Sharon Ann Moore

Dissertations and Theses

The purpose of this study was to compare NSST data (Lee, 1969, 1971) with data obtained in Portland, Oregon for children 4.0-4.11 years of age. The questions this study sought to answer were: 1) Is there a significant difference between the expressive and receptive scores obtained by Lee, (1969, 1971) and the scores obtained in Portland, Oregon? 2) What are the means, standard deviations and percentiles of the NSST scores of a select group of four-year-old children in Portland, Oregon?

Juvenile Delinquency In Saudi Arabia, Yousef Ahmed Alromaih

Dissertations and Theses

The present study involved an examination of the delinquency problem in Saudi Arabia within the framework of social control theory. Specifically, the study was based on the thesis set forth by Travis Hirschi, i.e., that delinquent acts result when an individual's bond to society is weak or broken. Also taken into account, however, were the findings from the research of Wiatrowski, et al. that suggest a need for a) some modifications in Hirschi's conceptual framework and b) inclusion of socio-economic factors in the social control model.

A Comparative Study Of The Teem And The Morphological Aspects Of The Blst And Told-P, Kathleen Marie Zuehlsdorff

Dissertations and Theses

The purpose of this investigation was to examine the construct validity of a new test, which purports to measure morphology, entitled Test for Examining Expressive Morphology (TEEM) (Shipley, Stone and Sue, 1983). Additional tests of expressive morphology, the Bankson Language Screening Test (BLST) (Bankson, 1977) and the Test of Language Development-Primary (TOLD-P) (Newcomer and Hammill, 1982) were utilized to determine the association of the TEEM with two highly-researched instruments.

Forecasting For Local Water Management, Douglas Alan Putnam

Dissertations and Theses

Forecast models are investigated and developed for use in local water management to aid in determining short term water requirements and availability. The forecast models include precipitation occurrence and depth using a Markov chain model, temperature and solar radiation with a multivariate autoregressive model, and streamflow with autoregressive-moving average models. The precipitation, temperature, and solar radiation forecasts are used with a soil moisture model to determine water demands. A state space approach to the Muskingum-Cunge streamflow routing technique is developed. The forecast water demands and streamflow forecasts are used as inputs to this routing model. Forecast model errors and propagation …

A Comparison Of The Effects Of Emg Biofeedback And Relaxation Training On Chronic Back Pain Patients, Pam W. Vredevelt

Dissertations and Theses

This experiment examined the effects of EMG biofeedback and relaxation training as compared with biofeedback alone. The following dependent variables were examined: manifest anxiety, perceived pain, perceived relaxation, EMG activity, and locus of control. Back pain patients were assigned to one of two treatment groups. Group 1 was treated with both EMG biofeedback and relaxation training. Group 2 was treated with biofeedback alone. It appears that both biofeedback combined with progressive relaxation and biofeedback training alone are effective in lowering muscle activity and perceived pain, and in increasing perceived relaxation. However, from the results of this study, it is impossible …

Geochemistry Of Alteration And Mineralization Of The Wind River Gold Prospect, Skamania County, Washington, Krista I. Mcgowan

Dissertations and Theses

The Wind River gold prospect is located in TSN, R7E of Skamania County, Washington, and is an epithermal gold-quartz vein system hosted in volcanic rocks of the Ohanapecosh Formation, a late Eocene to middle Oligocene unit of calcalkaline chemical composition. Andesitic pyroclastic rocks of the Ohanapecosh Formation are the host of mineralization in the study area, and form the lowest of several stratigraphic subunits. These pyroclastic rocks are overlain by two sequences of lava flows which cap the ridges and are folded by an anticlinal warp over the length of Paradise Ridge, plunging gently to the southeast. Toward the west, …

Geology And Geochemistry Of Hydrothermal Alteration, Eastern Portion Of The North Santiam Mining Area, J. Michael Pollock

Dissertations and Theses

The Ruth Mine is a base-metal vein deposit near the eastern margin of a reported porphyry copper deposit in the Western Cascade Range in Oregon. Uplift of the Western Cascade Range has resulted in a deeply dissected terrain in which more than a kilometer of the stratigraphy overlying the porphyry-style mineralization is preserved and exposed. The stratigraphic units, which are middle Tertiary in age, have been given arbitrary letter designations beginning with the lowest unit (Unit A) through the uppermost unit (Unit D).

Unit A is composed of fragmental rocks of andesitic composition. Overlying and interlayered with Unit A are …

The Effect Of Subject Expectations Of "Hypnosis" Upon The Vividness Of Visual Imagery, Kayla Mae Nilsson

Dissertations and Theses

There is no consensus of how hypnosis works. The two major theorists in hypnosis research, the Phenomenologists and the Behaviorists, disagree on this issue. The Phenomenologists consider individual talent and change of the state of consciousness the key to how hypnosis works. The Behaviorists consider the social situation and the roles taken by the experimenter and subject, especially the subject's expectations of hypnosis, the mainspring of the hypnotic process. Subject expectations of hypnosis have been found to affect the final results of hypnosis experiments. An experiment was conducted to gain further insight into subject expectations of hypnosis, and how these …

Aspects Of Cardiovascular Oxygen Transport In Vertebrates, Michael Scott Hedrick

Dissertations and Theses

The hematological and rheological characteristics of blood from a number of vertebrates was compared to assess possible species differences in blood viscosity that may influence cardiovascular oxygen transport. Nucleated red blood cells (RBCs) were more viscous (measured by cone-plate viscometry) in comparison with enucleate (mammalian) RBCs at hematocrits greater than 40% when measured at equivalent temperatures. The lower viscosity of enucleate RBCs is attributed to an enhanced deformability of enucleate cells in comparison to nucleated cells.
