Recidivism And The Self Concept Of Male Juvenile Delinquents, Mary B. Stelma

Masters Theses

It is a common belief that a low self concept is related to deviant behavior. The purpose of this study was to compare the self concepts of juvenile recidivists with those of non-recidivists.

A sample of 162 subjects was taken from juveniles who had been treated at a Michigan detention facility. Measures of self concept, using the Tennessee Self Concept Scale (Fitts, 1965), were taken both prior to and following treatment. Point-biserial correlations were computed for pre-test scores, post-test scores, and changes in scores from pre-test to post-test.

The results showed some significant positive correlations between self concept and recidivism …

Effects Of Intervention On The Ability Of Students With Hearing Impairments To Write Personal Narrative Stories, Beth L. Miller

Masters Theses

This study was designed to determine whether students with hearing impairments could be taught to write more mature personal narrative stories. An experimental group of junior high students received intervention focused on teaching the elements of story grammar and their application to the students' written narrative stories. A matched control group of students spent equal time with the researcher and received intervention focused on improvement of basic language skills. Pretest, posttest-1, posttest-2, and generalization samples were taken. Students' metatextual skills for telling how to write a story were also probed.

A significant difference was found between the experimental and control …

Evaluation Of The Effectiveness Of An Educational Presentation In Increasing Chemically Dependent Males’ Report Of Sexual Abuse, Linda L. Hand

Masters Theses

Research has demonstrated several factors among sexually abused males such as males sexually abused as children becoming adult sexual abusers; one in four males reporting sexual abuse; and adult emotional trauma, drug abuse, and sexual dysfunction. To break this abuse pattern, we need to focus on increasing males' reports of sexual abuse and initiating treatment.

The present study evaluated the effectiveness of an oral educational presentation in increasing males' reports of sexual abuse. It also sought prevalence information and treatment needs. Subjects were 51 males from three chemical dependency treatment centers. One control and four experimental groups were used. The …

The Purposeful Use Of An Object In The Development Of Skill With A Prosthesis, Hon Keung Yuen

Masters Theses

Theoretically, perceptual information from the interaction with an object and its surfaces (an affordance) facilitates the development of motor skill. This study investigated the use of an affordance in learning control of flexion and extension of an above-elbow training prosthesis. Fifty-two male college students were randomly assigned to two training procedures: two, 1.5-minute periods of a joining dots activity with a flashlight attached to the hook of the prosthesis (affordance group), and practice moving the prosthesis at the elbow joint (no-affordance group) for the same amount of time. To assess generalization of skill to a different task, each subject traced …

The Prenatal Development Of The "Synaptic" Structures In The Guinea Pig Pineal Gland, Zhongrong Luo

Loma Linda University Electronic Theses, Dissertations & Projects

Pineal "synaptic" ribbons are a heterogeneous population of organelles. In addition to "synaptic" ribbons (SR) sensu stricto, which are electron-dense rods, "synaptic" spherules (SS) and intermediate forms (IMF) are present. The SS are electron-dense spherical structures, the diameter of which is two to three times the width of the SR. The IMF appear as irregularly formed structures. The SR, SS and IMF are surrounded by electron-lucent vesicles. Their function and origin are unknown and also a knowledge of their prenatal development is lacking. In order to gain an insight into the development of the "synaptic structures, the pineal glands …

Dietary And Hormonal Evaluation Of Men At Risk For Prostate Cancer, Donald J. Pusateri

Loma Linda University Electronic Theses, Dissertations & Projects

Relationships between dietary nutrients and plasma and fecal estrone, estradiol-17β, testosterone, and plasma prolactin levels were studied in young Seventh-day Adventist men: 18 nonvegetarians (NV), 20 lacto-ovovegetarians (LOV), and 15 vegans (V). Blood samples and 3 d dietary records were obtained. Contemporaneously collected diet composites and stool samples were analyzed for fiber. The vegetarians consumed significantly more fiber than the omnivores, while NVs and LOVs consumed more saturated fat than the Vs. Although plasma steroid hormone status did not differ, the Vs had significantly higher fecal estrogen levels than the NVs or LOVs. Plasma prolactin levels were significantly higher in …

The Psychological Needs Of Sex Offenders Of Children As Measured By The Personality Research Form, Shirley Anne Miller

Dissertations

Major contributors in the field of child sexual abuse have agreed that sex offenders who sexually abuse children are not primarily motivated by sexual desire and have proposed that the simultaneous satisfaction of a number of psychological needs is the prominent motivation of sex offenders of children. Few attempts have been made to empirically validate the clinical and theoretical impressions regarding the psychological needs of this group using psychological measures designed to assess needs or motives.

The purpose of this study was to investigate to what extent the assumptions about the psychological needs of sex offenders of children would be …

Coverbal Behavior Of Aphasic And Right Hemisphere Damaged Subjects In Conversation, Jill Duvall

Dissertations and Theses

The frequency and duration of six coverbal behaviors were examined in two experimental groups and one control group. Conversational samples of ten aphasic subjects, ten right hemisphere damaged (RHD) subjects, and ten matched, non-brain damaged (NBD) control subjects were scored for frequency and duration of eye contact, head nod, head shake, head tilt, smile and eyebrow raise. Only the frequency of smile was found to differ significantly; the RHD subjects smiled less often than either of the other two groups.

Interactions Between Aquatic Chromogenic Bacteria And Pathogenic Vibrio Spp., John Louis Harris

Biological Sciences Theses & Dissertations

Interactions between populations inhabiting an ecosys­tem are responsible, in large part, for determining which species coexist in that ecosystem. In this study, interac­tions between selected Vibrio species, V. alginolyticus and V. anguillarum, and marine heterotrophic, chromogenic bac­teria in aquatic microcosms were investigated. The ultimate goal of this project was to evaluate the feasibility of ex­ ploiting competitive interactions as a means to biologically control growth of the pathogenic marine bacteria, V. alginolyticus and V. anguillarum. In the majority of ex­periments (14/16), if chromogenic species were allowed to develop stable populations before a Vibrio spp. was intro­duced into a …

A Method For The Large Scale Purification Of Hcg (Human Chorionic Gonadotropin) From The Urine Of Pregnant Women, Chun-Shyan Kuo

Chemistry & Biochemistry Theses & Dissertations

A large scale preparation of human chorionic gonadotropin (HCG) from the urine of pregnant women was accomplished by using kaolin adsorption, NH₄OH extraction and DEAE-cellulose ion exchange. A recovery about 81% of HCG and a specific activity in the 2,000-3,000 IU/mg range was achieved using this purification method.

Two HCG activity fractions, HCG I & HCG II, were isolated from DEAE-cellulose chromatography by a stepwise sodium chloride gradient elution. HCG I was eluted at 0.01-0.02 M NaCl while HCG II was eluted at 0.12-0.02 M NaCl.

The differences between HCG I and HCG II have been studied. The …

The Synthesis And Evaluation Of 5-Phenyloxazolidines As Potential Cardiovascular Drugs, Tammy C. Wang

Chemistry & Biochemistry Theses & Dissertations

Drugs such as adrenoceptor antagonists and certain centrally acting agents are known to lower blood pressure and thus serve as clinically useful antihypertensive agents. Norepinephrine 4, a natural ∝-adrenoceptor agonist, is the major agent associated with increased blood pressure in the periphery. Based on a careful structure-activity comparison, a series of substituted oxazolidines, 20, 21, 22 and 23, have been designed as possible antihypertensive candidates. Specifically, 22 and 23 have been synthesized to serve as potential norepinephrine antagonists.

Preliminary evaluation of these compounds indicated that they were not antihypertensive in nature. The more active compound, 23, …

Loma Linda University Electronic Theses, Dissertations & Projects

Enzyme II^mtl of Escherichia coli was purified from mtlA-overexpressing E. coli strain LJ1112 extraction of isolated membranes with deoxycholate, followed by hexyl agarose and ω-amino hexyl agarose chromatography in Lubrol PX. A 10-fold increase in total pure protein and 2.5-fold increase in specific activity over previously reported procedures was obtained. Tryptic fragments of Enzyme II^mtl were also purified and identified as the membrane and cytoplasmic domains by protein sequencing and SDS-PAGE. The fluorescence spectrum of Enzyme II^mtl suggested that two populations of tryptophan residues existed with emission maxima at 322 and 344 nm, corresponding to buried …

The Inhibition Of Bone Formation Occurring Under Weightlessness : The Effect Of Skeletal Unloading On Serum Levels Of A Bone-Derived Growth Factor, Jean D. Sibonga

Loma Linda University Electronic Theses, Dissertations & Projects

A deleterious effect of spaceflight on human health is the loss of bone associated with the prolonged lack of gravitational stress on the skeleton. A potential for bone loss is indicated by the hypercalciuria and decreased heel bone density determined in Skylab astronauts. Histological studies of juvenile laboratory rats in actual spaceflight and in simulation models document a suppression of bone formation with little alteration of bone resorption. The mechanism for net bone loss needs to be defined in order to develop measures for its prevention or correction.

Skeletal growth factors, which may mediate coupling and locally regulate bone volume …

Age-Related Changes In Meissner Corpuscles Of Diabetic Mice As Observed By Electron Microscopy, Vicky R. Ras

Loma Linda University Electronic Theses, Dissertations & Projects

Light touch and low-frequency vibration sense are often impaired in diabetic patients. Meissner corpuscles are distally located mechanoreceptors that respond to these stimuli. Peripheral sensory neuropathy in diabetes progresses from distal to proximal, therefore, Meissner corpuscles are ideally suited to study diabetic neuropathy in the C57BL/Ks (db/db) mouse.

Corpuscles from the forepaw digital pads of 9 diabetic and 9 nondiabetic littermates were studied by electron microscopy. These were divided into 3 age groups; 2.5 months, 10 months, and 17 months old.

Ultrastructural changes observed within various receptor components were myelin figures, multivesicular bodies, vacuoles, basal lamina duplication, abnormal and enlarged …

Increasing The Self-Esteem Of Junior High Emotionally Disturbed Boys, La Rue Eaton Richey

Graduate Theses

Emotional disturbance can be viewed as an inability to manage one's behavior. This inability to maintain self-control in stressful situations represents a serious problem not only for the individual but for family and school personnel. In this study, Reasoner's (1984) Building Self-Esteem program was used with seventh and eighth grade emotionally disturbed boys in a West Texas community. Their self-esteem scores did increase as measured by Coopersmith (1984) Self-Esteem Inventory. *

All-Inclusive List of Electronic Theses and Dissertations

Psychology has enjoyed tremendous growth and increasing professionalization in the years following WWII, with the major thrust of this growth being in professional practice. This period has also witnessed a rapid transformation in the educational and sociopolitical underpinnings of professional training and practice. Many authors have studied the growth of practice by periodically surveying practitioners and commenting on a wide variety of demographic, professional and practice-related characteristics. This paper reviews these surveys, noting trends in the characteristics of the human resource pool and the factors both within and external to the profession that have contributed to the shape of those …

A [6-14c] Glucose Autoradiographic Study Of The Rat Brainstem Under Hypercapnic And Hypocapnic Conditions: Identification Of Respiratory-Related Regions, Tobey M. Leung

Loma Linda University Electronic Theses, Dissertations & Projects

The effects of systemic hypercapnia on brainstem metabolism were studied with the [6-¹⁴C] glucose autoradiography method. Neuronal pools which are metabolically active take up more [6-¹⁴C] glucose and maybe revealed pictorially as darker areas on autoradiograms. Since a high concentration of carbon dioxide stimulates central chemoreceptors and hence enhances respiratory drive, the darker regions on the autoradiograms may represent regions concentrated with respiratory-related neurons. Two discrete regions in the ventrolateral medulla (a column near nucleus ambiguus and a column in the lateral reticular nucleus) appeared dark and were analyzed with an image processing system, which converted …

Comparison Of Five Different Serological Assays For Determination Of Antibody Levels Against Herpes Virus Type 1 And 2, Murat Sami Küçük

Loma Linda University Electronic Theses, Dissertations & Projects

To aid in the diagnosis of certain clinical types of Herpes virus infections, we evaluated and compared five serological methods for measuring Herpes virus antibody. The five tests we compared are complement fixation test (CF), indirect immunofluorescent antibody assay (IFA), anticomplementary immunofluorescent assay (ACIF), enzyme linked immunoassay test (ELISA), and the latex agglutination test (LA). The main objective of this study was to establish which of the currently available serologic tests was best suited for clinical laboratory use and which may then replace the complement fixation test. In the comparative testing, one hundred twenty serum samples were divided into four …

An Investigation Of The Effect Of Using Varying Stimuli To Assess Normal Children's Comprehension Of Five Locative Prepositions, Kathleen G. Versteeg

Dissertations and Theses

A recurring concern in recent research appears to be the role that assessment variables play in accurately measuring children's knowledge and use of prepositions. Age and order of acquisition of prepositions has become a dynamic rather than static standard, as different ways of assessing prepositions also give different results. These researchers have investigated assessment variables such as context (picture, object, no context) and response (self actions, manipulating, pointing) in assessing normal children's understanding and use of prepositions. Most have considered these variables separately, but a few have contrasted a limited number of variables with significant results for some age groups. …

Eating Disorders: The Correlation Of Family Relationships With An Eating Disorder Continuum, Jana Schweitzer

Dissertations and Theses

For the purposes of this study, eating disturbances were placed on a continuum ranging from disordered to normal, and family factors were examined via this framework. Research on anorectics and bulimics indicates that a variety of family variables contribute to the etiology of eating disorders. Research suggests the presence of a subgroup of persons who experience some disturbance in their relationships with food but not to the severity observed among eating disordered individuals. This study examined the relationship between family factors and eating disturbances.
