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 …

Regeneration Of Meissner Corpuscles In Diabetic Mice Following Median Nerve Crush, Bonnie J. Forrester

Loma Linda University Electronic Theses, Dissertations & Projects

The hyperglycemic metabolic condition found in diabetes mellitus leads to the development of sensory neuropathies and causes delayed and incomplete neuronal regeneration. Diabetic sensory neuropathy has been shown to contribute to the impairment of light touch and low frequency vibratory perception. It is proposed that the regeneration of receptors that detect these sensations will be delayed and incomplete in diabetic animals with uncontrolled hyperglycemia. This study addresses the effects of diabetes on the regeneration of Meissner corpuscles, distal sensory endings that perceive light touch and low frequency vibration.

Corpuscles from 60 diabetic mice, and their age-matched, non-diabetic littermates, were examined …

A stratified random sample included 28 hospital diploma, 41 associate degree and 37 baccalaureate degree nurse educators from the Commonwealth of Virginia, who completed the Nurse Educator Questionnaire (NEQ). Two free-response questions were used to identify factors which the nurse educators perceived as inhibitors and facilitators to research utilization. The results of a two-step mailed …

Factors Determining Peripheral Vascular Disease Clients' Intent To Adhere To Prescribed Behaviors, Gretchen Grahn Hitchcock

Ellmer School of Nursing Theses & Dissertations

Motivation of clients with Peripheral Vascular Disease (PVD) to adhere to Recommended risk-reducing behaviors (RRB’s) was explored. The sample (n =30) was comprised of clients in a vascular physician group’s practice with a medical diagnosis of PVD. A nonexperimental, descriptive design was utilized to investigate how much variation in adherence to RRB’s by PVD clients could be accounted for by the client’s perceived effectiveness of a RRB and the client’s perceived difficulty in adhering to a RRB. A self-administered three part instrument, a demographic data form, and a self-administered qualitative data form were utilized to collect the data. Regression analysis …

Self-Esteem And Perceived Barriers To And Benefits Of Exercise Among Physically Active And Non-Physically Active College Students, Barbara Brown Bonheur

Ellmer School of Nursing Theses & Dissertations

The purpose of this exploratory study was to examine differences in self-esteem, perceived benefits of and perceived barriers to exercise between exercisers and non-exercisers and to determine if relationships existed between self-esteem, perceived benefits of exercise and perceived barriers to exercise, that could explain participation in regular aerobic exercise. A sample of 105 university students completed four questionnaires. The level of social desirability present in participant responses was also measured. Five hypotheses were tested. Utilizing t-tests, a significant difference was found between exercisers and non-exercisers on self-esteem, perceived benefits of exercise, and perceived barriers to exercise. The three variables (self-esteem, …

Disfluencies In Normal Four-Year-Old Alaska Native And Caucasian Children, Annette Cameron O'Connell

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 …

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 …

Smoking Cessation In Relapsed Smokers: A Competing Schedules Approach, Catherine E. Ellis

Masters Theses

Recent research in cigarette smoking reveals that social support and reinforcing alternative behaviors to smoking may be instrumental for sustained abstinence. This study examined the efficacy of these approaches with a group of relapsed smokers. Subjects were fifteen male and female Southwestern Michigan residents between the ages of 22-48. Both the treatment and control group attended two initial smoke-stopping sessions. The independent variable was a relapse-prevention package administered to the treatment group over the third through seventh sessions. Dependent variables were Carbon Monoxide (CO) levels, Saliva Thiocyanate (SCN) levels, and the daily number of cigarettes smoked. A two-way analysis of …

A Social Exchange Approach To Explaining Satisfaction With Therapy, Brenda B. Counts

Psychology Theses & Dissertations

The present study examined the effect of Reward, Cost, Comparison Level, Comparison Level of Alternative, and Investment on Satisfaction and Commitment in therapy from the perspective of social exchange theory and the investment model. Relationship variables were assessed by 114 subjects for the beginning of therapy, the first few sessions: middle of therapy, when therapy was clearly underway and issues were being dealt with; and the end or last few sessions. Results confirmed that Satisfaction and Commitment were significantly predicted by greater Reward, lower Cost, and Comparison Level. Investment was consistently positively related to Commitment and not to Satisfaction. However, …

Hypoxanthine-Induced Differentiation Of Cultured Human Leukemia Cells, Gayle Jennette Singleton

Chemistry & Biochemistry Theses & Dissertations

Human cultured leukemia cells appear to have a decreased amount of inosine in their tRNA. When cells with inosine deficient tRNA are placed in a hypoxanthine fortified media, they incorporate hypoxanthine into their tRNA by the action of the enzyme tRNA-hypoxanthine ribosyl transferase. This generates the nucleoside inosine in the tRNA. The cultured human leukemia cell lines, CCRF-CEM, HL-60, and HGPRT(-) HL- 60, incorporate hypoxanthine into their tRNA, as determined by tRNA isolation, hydrolysis, and HPLC analysis. Hypoxanthine treatment dramatically inhibited cell growth in conjunction with partial induction of differentiation in the CCRF-CEM, HL-60, and HGPRT ( - ) HL-60 …

Isolation And Partial Characterization Of Basic, Sperm-Specific, Nuclear Proteins In The Dog And Hampster, Richard William Hall

Biological Sciences Theses & Dissertations

The purpose was to determine whether dogs and hamsters contain the same sperm-specific protamine and testis specific proteins (TP) as other eutherian mammals previously studied. The proteins (protamine and TPs) were isolated from spermatids and mature spermatozoa, and were subjected to electrophoresis in an acid-urea, polyacrylamide gel system according to the procedure of Panyim and Chalkley (1962). The results indicated that, regardless of the anatomical location of sperm acquisition, acid precipitation technique, or denaturing agents used, epididymal and testicular samples from both the dog and hamster contained protamine in elongated spermatids and mature spermatozoa. The protamines from dogs and hamsters …

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?

'Night Duty' : A Study Of Nurses' Attitudes Toward Night Duty, With Implications For Hospital And Nursing Management, Beth Louise Brown

Theses : Honours

Research specifically related to the needs and attitudes of nurses to night duty is in its infancy. Nurses have previously been included in studies related to circadian rhythms, and job satisfaction but only recently have complex aspects of the adaptation to working at night in health care institutions been given consideration. Shift work in general, has been identified as a stressful, occupational health hazard. Nurses cannot be compared to other shift workers. Chronobiological research now confirms that many individuals are unable to adapt to night work. This is in contrast to the historical management view which held the opinion that …
