An Inquiry: The Concept And Application Of Empowerment, Pamela Kay Wheelock

Masters Theses

While empowerment is a dominant concern in mental health care, services often reflect the inadequate use of an empowerment-based frame of reference. This study seeks to enlarge the understanding of empowerment so that more effective services can be established.

Using naturalistic inquiry methodology, this study explores the lived experience of empowerment through direct dialogue with both mental health consumer advocates and mental health occupational therapists. Data were collected and evaluated using a hermeneutic dialectic process. A series of three interviews were done with six respondents.

Analysis of the interviews revealed striking contrasts between the therapists' and advocates' perspectives in relation …

Negotiating The Healthy Self: A Theory Of Health Behavior In Older Adults, Barbara Schwitz White

Loma Linda University Electronic Theses, Dissertations & Projects

Researchers have identified discrete behaviors of older persons to maintain or improve health and prevent or treat illness. Few have developed theories of health behavior specific to this population. The purpose of this study was to develop a substantive theory to explain how health and illness are integrated into and influence behaviors in the daily lives of community-residing older persons. Using grounded theory design and analysis, 26 participant observations involving 186 individual encounters, and seven semistructured [sic] one-on-one interviews were conducted at two senior centers in urban southern California, between 1992 and 1994.

Bone Morphogenetic Proteins And Periodontal Repair, Michael B. Lee

Loma Linda University Electronic Theses, Dissertations & Projects

For over thirty years now, research has been carried out to isolate and purify bone morphogenetic protein (BMP), a substance which has been shown to induce heterotopic bone formation in various animal species. Recent advances in the fields of developmental biology, molecular biology and genetics, have shown that the BMPs not only are responsible for postfetal bone induction (including normal bone remodeling, healing and repair), but are also critical during embryogenesis - not only in regards to the skeletal system, but quite possibly in the morphogenesis and pattern formation of other tissues and organs as well.

Due to their bone …

The Effects Of Lowering Cholesterol On Vasodilation, Maria Christi Hardt

Loma Linda University Electronic Theses, Dissertations & Projects

Endothelial dysfunction has been found prior to any signs of atherosclerotic plaque formation in patients with a variety of risk factors for atherosclerosis. Elevated serum cholesterol has repeatedly been associated with endothelial dysfunction as demonstrated by impaired vasoreactivity to vasodilating stimuli.

The aim of this research was to determine whether short term lowering of serum cholesterol levels by life style changes or by cholesterol lowering medication could reverse or reduce the endothelial dysfunction. The brachial artery diameter was measured by high-resolution ultrasound at rest and during reactive hyperemia pre and postintervention. Fifty-three subjects with cholesterol levels above 240 mg/dl were …

Pediatric Intensive Care Nurses : Post-Traumatic Stress Disorder-Like Symptoms, Juanita J. Allen

Loma Linda University Electronic Theses, Dissertations & Projects

Medical personnel are not only exposed to routine pressures of demanding roles, but research reveals that they can suffer from severe stress related to exposure to critical incidents. These events can overwhelm an individual's ability for emotional adjustment leading to negative symptoms such as emotional numbing, mood changes, estrangement from friends or family, decreased ability to perform or function on the job, development of posttraumatic stress disorder (PTSD) symptoms, loss of work through attrition, and depression. Contact with seriously injured children or children who have died has been shown to constitute just such a critical incident for pre-hospital care personnel …

Neither ferric sulfate nor aluminum chloride exhibited mutagenic potential, in comparison with glutaraldehyde and formocresol, which …

Understanding Ki In The Daily Experience Of Advanced Practitioners Of Aikido: A Phenomenological Study, Steven C. Andress

Dissertations and Theses

Ki, Japanese for living energy (Chi in Chinese), is at the absolute core of the Oriental model of medicine and wellness. Complementary to this model, many Oriental martial art exercises have evolved to cultivate Ki for optimal health. However, the concept of Ki remains poorly understood and relatively unexplored in traditional Western health and medical literature. Further, the health focus of martial art research has remained primarily concerned with the arts' contribution to psychological health. This has left a significant gap in our understanding of the other health benefits that these arts and Ki have to offer. To begin closing …

A Correlative Study Of An At-Risk Population And Low Birth Weight/Infant Mortality In A Northeast Oklahoma City Community, Estacia D. Thrower

McCabe Thesis Collection

Studies show that numerous and complex variables influence pregnancy outcomes and infant mortality rates. These variables include demographic, medical, physical, environmental, behavioral, and attitudinal factors and prenatal care. Improving the health of mothers and infants is a national challenge. In 1987, more than 3.8 million infants were born in the United States. Of these, 38,408 died before their first birthday. Although the infant mortality rate is at an all-time low, the pace of progress has slowed. According to Dr. Robert Deppen of the Oklahoma State Health Department, "In 1992, Oklahoma ranked 29th in the United States for infant mortality and …

The Cloning And Characterization Of Toad-64: A Gene Expressed Transiently During Neuronal Differentiation In The Mammalian Nervous System, Jane Elizabeth Minturn

Yale Medicine Thesis Digital Library

During the development of the mammalian central nervous system, a pool of morphologically homogeneous, mitotically active progenitor cells in the neural tube gives rise to the enormously diverse population of postmitotic cells that assume the properties of neurons or glia. Postmitotic neurons elaborate processes that are involved in the migration of neurons to their adult positions as well as the elaboration of axonal and dendritic arbors that will ultimately form specific synaptic contacts. The generation of postmitotic neurons from precursor cells is a central differentiative event in development, but molecular markers of this event are few.Using 2D gel electrophoresis, proteins …

Criteria Used In Assigning A Diagnosis Of Passive-Aggressive Personality Disorder, Laura J. Hunsucker

All-Inclusive List of Electronic Theses and Dissertations

Genetic And Biochemical Characterization Of Drosophila Singed, A Homolog Of The Actin Bundling Protein Fascin, Kelly Cant

Yale Medicine Thesis Digital Library

Drosophila singed mutants were named for their gnarled bristle phenotype, however, severe alleles are also female sterile due to a defect in nurse cell cytoplasm transport. Recently, singed protein was shown to have 35% peptide identity with the actin bundling protein fascin. I present evidence that singed is a homolog of fascin. In vivo, singed is required for actin filament bundle formation in the cytoplasm of nurse cells during oogenesis and in the cellular extension that forms a bristle. In vitro, purified bacterially-expressed singed bundles actin filaments with the same 12 nm periodicity and stoichiometry reported for sea urchin fascin.While …
