The Acquisition Of Five Specific Morphemes By English-Speaking Preschool Children, Maxine Ulyate

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of the present research was to study the acquisition of the morphemes involved in the production of the noun plural and possessive, the present progressive tense, the third person singular of the verb and the regular past tense. Research had documented that a time lapse existed between the time that a child was able to correctly inflect a common English word and when he could correctly inflect a phonetically similar nonsense item. This lapse appeared to be the time during which the child formulated an internal rule for the production of each morpheme.

The methodology involved testing sixty …

Diagnostic Comparison Between Free Speech Samples And Imitation Tasks, Tina Valcarenghi

Loma Linda University Electronic Theses, Dissertations & Projects

This study investigated and compared the advantages and disadvantages of a free speech sample and imitation type task in analyzing language performance in kindergarten children. An analysis of the language performance of 15 children was completed. Their language ranged in severity from normal to severely delayed. The children were divided into three distinct subgroups; severely delayed, moderately delayed and normal. The subject's scores were analyzed to determine if there was a significant difference in the reliability of these two measures and in the sensitivity in identifying presence and severity of disorder.

A Comparative Analysis Of Intrusion Of Incisor Teeth Achieved In Adults And Children According To Facial Type, Ronald L. Otto

Loma Linda University Electronic Theses, Dissertations & Projects

A comparison of incisor intrusion achieved in deep bite adults and children was made. Facial type was also examined for affect upon intrusion achieved. Fifty-five cases treated with Bioprogressive mechanics were studied cephalometrically, including twenty-four adults and thirty-one children. Neither age nor facial type was found to be statistically related to the amount of incisor intrusion achieved in this sample. A method of measuring intrusion at the root apices was devised which was felt to give a more accurate indication of actual bodily intrusion. More external root changes during treatment were observed for adults than for growing children. Wide latitude …

The Effects Of Orally Administered Charcoal On Intestinal Gas, Herbert J. Thompson

Loma Linda University Electronic Theses, Dissertations & Projects

Our primary objectives were to determine if orally administered charcoal effectively decreased intestinal gas, and relieved subjective symptoms associated with a high gas producing meal.

The adsorptive properties of charcoal for those gases usually found in intestines (CO₂, H₂, CH₄, H₂S) were first tested by placing measured samples of each gas alone with weighted samples of activated charcoal in a respirometer.

The degree of adsorption of each gas by charcoal was determined. Charcoal effectively adsorbed H₂ and CO₂.

A group of normal human males were fed a gas producing …

Fatigue Properties Of Orthodontic Wire, Kirkland B. Reuer

Loma Linda University Electronic Theses, Dissertations & Projects

Fracture of orthodontic appliances can be a problem because of the time involved to replace and repair them. It has been shown that most failures have been a result of fatigue fracture, i.e., failure resulting from cyclic loading.

The purpose of this study was to determine what effect variation of the type of orthodontic wire and heat treatment had on fatigue resistance. A device was constructed to put a cyclic load on a piece of wire until fracture. Two types of cobalt-chromium alloy wire (Blue and Green Elgiloy from Rocky Mountain Orthodontics) and three types of stain less steel wire …

The Effect Of Primary Nursing On Nurse Job Satisfaction And Patient Satisfaction With Nursing Care, Karen Garrison

Loma Linda University Electronic Theses, Dissertations & Projects

Nursing as a profession has seen the loss of large numbers of practitioners through job dissatisfaction. In addition, recent studies testing professional growth among new graduates have demonstrated negative findings. Lack of responsibility and accountability have been indicated as potential causes of these problems which confront professional nursing.

In nursing modalities such as functional, case method and team nursing the lack of autonomy in providing care is visible. The team nursing approach fragments patient care; a nurse in this system is responsible for team members rather than directly for patients. The registered nurse does not have enough personal contact in …

The Effects Of Morning And Afternoon Scheduling On The Clinical Performance Of Severe Aphasic Adults, Judith Ann Fisher

Dissertations and Theses

Concern regarding variables which influence the performance of aphasic adults has been demonstrated in the literature. Marshall et al. (1978) found that one such variable, scheduling of intervention, influenced significantly the test performance of their subjects. They determined that the aphasic subjects performed better in the morning than in the afternoon. The purpose of the present study was to determine if performance of severe aphasic adults on easy and difficult, single-word picture-identification tasks, presented in a clinically reinforcing manner, is differentially affected by morning and afternoon scheduling.

The questions posed in this investigation were: 1) Does morning versus afternoon scheduling …

Androgen-Induced Immunosuppression, Debra Ann Weyant

Dissertations and Theses

It is well established that females are more immunocompetent than males as evidenced by higher humoral antibody titers, lowered susceptibility to infection, and more efficient graft rejection.

Furthermore, females also exhibit a much higher incidence of autoimmune disease. These observations have led investigators to believe that the male hormonal environment may play a key role in the regulation of immune response. For this reason, this study is concerned with the expression of autoimmunity and of immune function in the mouse.

This study included the New Zealand Black (NZB) mouse strain, as an animal model for human SLE, as well as …

An Investigation Of The Consistency Of Stimulus Overselection Of Autistic Children, Patricia O'Meara Walker

Dissertations and Theses

A review of the literature indicated that not all of the research in the area of overselectivity of autistic children has been in agreement. It does seem evident that some autistic children overselect. This could be the result of an attentional factor or a modality preference. This has important implications for the education of autistic children. In the light of the inconsistency of autistic children's reactions to sensory stimuli this investigator believed there was a need to determine if overselection is consistent before referring to the overselected modality as a preferred modality or comparing overselected modalities with the child's mode …

An Investigation Of Client Fluency Maintenance Between 1972-1977 At Portland State University, Pricilla Lynn Ginter

The Balb/c mouse response to the growing HSV-induced tumor, treated with radiation and , was measured by survival rate, tumor growth and immune cytotoxicity of spleen and peritoneal exudate cells (PEC) as determined by ¹²⁵IUdR release assay. Subcutaneous (s.c.) inoculation of 1 x 10⁶ H238 cells (high dose) produced progressive tumor growth while s.c. inoculation of 1 x 10⁴ H238 cells (low dose) produced no tumors. A …

Erythrocyte Transketolase Activity Measurements: Assessment Of Thiamine Status In Rat And Man, Marilyn Thomas Milchanowski

Biomedical Sciences ETDs

An individual's thiamine status can be assessed by the measurement of erythrocyte transketolase (ETK) activity and a new method for this type of measurement in rat and human whole blood hemolysate samples has been developed and completely automated. This assay is based on enzymatic activity of the hexose monophosphate shunt which involves interconversion of hexoses and pentoses and production of NADPH reducing power. All of the enzymes of the hexose monophosphate shunt (HMS) are present in erythrocytes, including transketolase (TK) which appears to be the rate-Iimiting enzyme in this reaction series. Reaction conditions are established to ensure a direct relationship …
