Dissertations and Theses

The purpose of this study was to evaluate the results of trained transport nurses being oriented to a new helicopter by a video presentation and reference guide manual educational program when compared with trained transport nurses being trained by actual hands-on demonstration. Using a posttest-only design and the t test for independent samples, it was found that the two groups of nurses did not differ statistically (t (9) = 0.318, p < .051).

Maternal Linguistic Input To Normal And Expressive Language Delayed Toddlers, Terril Joy Elwood

Dissertations and Theses

Research suggests that the linguistic environment of the expressive language delayed child is different from that of his peers. Does this difference actually exist and if so, what are its characteristics? The purpose of this study was to describe the linguistic characteristics of mothers' input to children with normal language acquisition and those of mothers of expressively delayed toddlers; and to identify any differences between these groups. Though considerable research exists in this area, few studies have dealt specifically with large groups of expressively delayed toddlers.

Integrating Psychological And Economic Perspectives On Energy Consumption: The Determinants Of Thermostat Setting Behavior, Jane Stromme Peters

Dissertations and Theses

Data obtained from two surveys of 283 residents of recently built homes in the Pacific Northwest were used to examine winter thermostat setting behavior. Attitude scales along with demographic, economic and dwelling structure data were used to estimate models of daytime, nighttime and average temperature setting choices. Two series of models were estimated: a partial model using demographic, dwelling structure characteristics and economic data; and an integrated model including the attitude scales.

The results of these analyses demonstrated that the inclusion of data on respondent attitudes toward comfort, conservation, health and cost control significantly improved the explanatory power of the …

A Comparative Analysis Of The Expressive Acquisition Of Locative And Directional Prepositions Between Severely-To-Profoundly Hearing Impaired Children Utilizing Total Communication And The Oral/Aural Approach, Cathleen Pew Edwards

Dissertations and Theses

Prepositions are not only important in functional syntax; they also relate meanings associated with the concepts of place and time. Furthermore, prepositions are critical in such everyday activities as producing and comprehending directions, using maps and diagrams, and in the fields of mathematics and music. Inefficient use or misuse of prepositional spatial terms may hinder a child's progress in many areas. Expressive acquisition of function words, which include prepositions, has been described as significantly delayed in the hearing impaired populations.

The purpose of this study was to conduct a comparative preposition analysis between hearing impaired children using two different modes …

Frequency Responses Of Hearing Aids Coupled With Fm Auditory Trainers, Robert Bruce Morrison

Dissertations and Theses

This study examined the frequency response characteristics of three behind-the-ear hearing aids alone and in combination with three FM auditory trainers. The hearing aids and FM auditory trainers were coupled using two different methods: direct audio input and personal mini-loop. Also, two different gain control settings were used. Frequency responses were evaluated using a template method specified in ANSI S3.22 1982 standards. A larger percentage of the personal mini-loop combinations failed to meet this ANSI standard as compared to the direct audio input combinations (72.3% vs. 50%). The frequency response curves for various combinations of hearing aids and FM auditory …

The Interaction Of Stimulus Rate And Polarity Effects On The Auditory Brainstem Response, Michelle Ann Nielsen Ziegler

Dissertations and Theses

Research on the Auditory Brainstem Response (ABR) has been dominated by attempts to develop techniques to enhance the clarity of the ABR waveform and to define the parameters that separate normal from abnormal responses. While the effects of stimulus rate are clearly documented, the effects of stimulus polarity on the ABR are not. There may be an interaction of polarity and rate which accounts for the inconsistent results reported in the literature.

This study examined the effect of stimulus rate and polarity for waves I, III, and V, on the ABR latency, amplitude, and amplitude ratio. Rarefaction and condensation clicks …

Designing An Instructor's Manual For Introducing Cultural Concepts In The Medical School Curriculum, Barbara C. Nicodemus

Dissertations and Theses

Medical educators recognize the need for including cultural insights into the training of future physicians. This instructor's manual suggests selected journal articles and guidelines for their use in each of the clinical courses to illustrate the relevance of culture, inter- and intraethnic differences, an attitude of cultural relativity, and the importance of language use and communications skills for medical practice. The articles are found in journals typically available to medical students. This manual provides a baseline integrative approach applicable to other specialized training programs. A recommendation is made for evaluation and revision of history-taking interview forms to elicit additional culture-specific …

An Estimation Of Relatedness Within Two Oregon Populations Using Isonymy Analysis, Maria Michalczyk

Dissertations and Theses

The study of human relatedness has long interested the population geneticist. One technique for the estimation of population relatedness is the use of isonymy analysis. The isonymy inbreeding coefficient is analogous to Wright's inbreeding coefficient F. Isonomy analysis can yield comparable results to population studies done by other means such as pedigree analysis, serological studies, and anthropometric analysis.

The data used for this study was obtained from marriage records and telephone directories. Same last name marriages were observed for legitimacy and recorded when verified. A pool of last names were drawn from the marriage records. This list was used to …

Dissertations and Theses

The purpose of this study was to compare the frequency of occurrence of specific speech disfluencies in 4-year-old Alaska Native children to those of 4-year-old Caucasian children. Specifically, eight disfluency types were investigated: part-word repetition, word repetition, phrase repetition, interjection, revision-incomplete phrase, disrhythmic phonation, tense pause, and intrusive schwa. The questions addressed in the study were:

1. Do 4-year-old Alaska Native children exhibit a higher frequency of disfluencies than 4-year-old Caucasian children?
2. Do 4-year-old Alaska Native children exhibit a greater frequency of specific disfluencies, in terms of part-word repetition, word repetition, phrase repetition, interjection, revision-incomplete phrase, disrhythmic phonation, tense pause, or …

Development Of Morphological Forms In Four-Year-Old Children, Catherine Anderson Thompson

Dissertations and Theses

The purpose of this study was to investigate morphological development in 4-year-old children. Two tests were utilized and compared to see if there was a significant difference between the expression of meaningful and nonmeaningful words. The first test, a modified version of the Test for Examining Expressive Morphology (TEEM), used meaningful words to assess allomorphic variations of six bound morphemes. The second test, a modified version of Berko's Test of English Morphology (BTEM), assessed the same allomorphic variations, but it used nonmeaningful words.

A Longitudinal Study Of The Disfluencies Of Four And Six Year Old Children, Mary B. Cox

Dissertations and Theses

Investigations into the speech of normal children have indicated that disfluencies are common. It is important for the Speech Language Pathologist to have knowledge of normal disfluencies for differential diagnosis, parent counseling, and in order to plan strategies for intervention.

The purpose of this study was to compare the frequency of disfluencies in 4 year old and 6 year old normal male children to the frequency of disfluencies when they were 3 years old and 5 years old, respectively.

One year later, eighteen of the twenty normal male children study used in a previous study were reevaluated in this. At …

A Longitudinal Study Of Disfluencies In The Speech Of Normal Preschool Children, Susan Marto Crowell

Dissertations and Theses

The process of differentially diagnosing a child who is experiencing temporary normal disfluency from one who is beginning to stutter could be made objective by the establishment of normative data on fluency development. To date, there are no standardized norms on the development of fluency in children. Current investigations have contributed greatly to expectations of certain types and amounts of disfluencies in preschool-age children. Most of the research, however, has focused on observing children at discrete age levels from 2- to 7-years-of-age. Only one longitudinal study to date has been reported. Additional longitudinal data of preschool-aged children would benefit the …

Exploratory Study: Preparation By Japanese Parents In The U.S. For Their Children's Reentry To Japan From An Intercultural Communication Perspective, Noriko Nakagawa

Dissertations and Theses

The purpose of this thesis was to discover whether or not the Japanese parents who are temporarily staying in the U.S. with their children are anticipating the possibility of psychological and communicative problems their children may face as returnees, and to what extent the Japanese parents discuss these potential problems with their husbands and/or with their children. The question also asked whether or not the Japanese parents are doing anything to prepare themselves and/or their children to cope with the potential problems which their children may face as returnees.

Attitudes Of Control And Weight Management, Carolyn Lee Edwards Wright

Dissertations and Theses

Applications of locus of control theory to weight loss programs have yielded inconsistent results. This study attempts to clarify "control" by looking at two different factors. Maximum control is the degree of perceived control inherent in the event itself, and personal control is the degree to which the event is perceived controllable by the individual. These two factors were also examined in two types of situations to determine whether individuals have one global outlook on control, or if they make a distinction between control in some situations as opposed to control in other situations. Seventy-four female subjects completed a 16 …

Experienced exchange coordinators, host families and others were interviewed for their suggestions of additional goals not discussed in the literature. A survey questionnaire was developed and administered to 69 host family members from Tillamook County, Oregon. They were asked to evaluate the importance and achievement of 14 literature-based and 22 …

In Situ Measurements Of Two Amplified And One Acoustic Stethoscope, Sara Ruth Ann Oliver

Dissertations and Theses

This study investigated the following questions: 1) What is the spectra of human heart sounds when transmitted to the listener's ear through amplified and acoustic stethoscopes? 2) How does the acoustic spectrum of normal heart sounds compare to the threshold of audibility for normal hearing sensitivity? 3) Do normal hearing listeners elect to listen to heart sounds at a higher intensity than the acoustic stethoscope is able to transmit?

A Model Of Suicidal Behavior In Latency Age Children Based On Developmental Object Relations Theory, Stephen Henry Michaelis

Dissertations and Theses

This thesis attempts to explicate the manifestation of suicidal behavior in latency age children based on developmental object relations theory. It asserts that the susceptibility to suicidal behavior becomes part of the child's developing ego organization during the first three years of life as the result of deviant or distorted emotional development. These disturbances interfere with the normal internalizing processes of the separation individuation phases, including the development of psychological mechanisms.

To accomplish the purpose of the study, the thesis generally classifies object relations theory within the parameters of developmental psychopathology and specifically classifies it as a component of contemporary …

Correlation Of Preschoolers' Performance On Three Language Comprehension Tests, Alissa Clare Nordlund

Dissertations and Theses

The purpose of this study was to determine the relationship between the Peabody Picture Vocabulary Test-Revised, (PPVT-R) and receptive subtest of the Preschool Language Scale (PLS), and between the PPVT-R and the Test of Auditory Comprehension of Language-Revised (TACL-R), as well as determine how the tests compare in identifying children in need of further evaluation in the area of receptive language. The reasoning behind the goal of this study was to determine that if the three tests showed a strong, positive correlation and identified the same children as needing further assessment, then perhaps the test which was easier and …
