Changes In Student Wellness Behaviors After Enrollment In Health Advocacy Courses At Und, Shelby J. Kary

Theses and Dissertations

Peer/health advocacy programs are used in the college and university setting to promote health education for students. Carns, Carns, and Wright (1993) found 83% of colleges and universities used undergraduate students in peer education programs. According to Mellanby, Rees, and Tripp (2000), "Peer-led education may be more effective, resulting in greater positive changes in health behaviour, than adult-led interventions" (p. 543). In the spring of 2005, Dr. Alan Allery, Director of Student Health Services at the University of North Dakota (UND), envisioned implementing a peer advocacy program at UND. A review of peer/health advocacy programs at other universities revealed that …

Literature Review; Culturally Competent Care For Native Americans With Mental Illness, Pamela V. Merrifield

Theses and Dissertations

There is a great n eed f or cu 1t urally competent nurse practitioners within the health care system H . . · owever, the literature 1s lacking regarding the utilization of services or the health-seeking behaviors of Native Americans with mental illness. There is increased morbidity and mortality afflicting racial and ethnic populations. Poor health of these populations may be attributed to poverty, lack of health care access, and cultural competence of health care providers (Geiger, 2001 ). As diversity increases within the general population, health care providers have a greater responsibility to become culturally competent to provide better …

Distribution, Abundance, And Habitat Associations Of The Long-Billed Curlew In Southwestern North Dakota, Daniel S. Ackerman

Theses and Dissertations

Gathering information on North American bird populations calls for long-term monitoring programs covering extensive geographic region to provide basic information on distribution, habitat use and availability, abundance, and changes in abundance. Information regarding population size, distributions and trends is of critical importance to conservation planners, managers, and biologists concerned with widespread degradation of ecosystems, alteration and loss of habitats, and understanding the effective conservation of a species. In accordance with the recommended monitoring of bird populations, especially species of high conservation concern, I undertook a study of the long-billed curlew (Numenius americanus parvus; hereafter LBCU or curlew). The LBCU were …

Effects Of Exposure To Perinatal Ultrasound Radiation On Information Processing In The Auditory System, Jennifer Burnett

Theses and Dissertations

Ultrasound (US) has become a standard procedure used during pregnancy to document the health and development of a fetus. When ultrasound was first developed, some researchers urged caution, suggesting that the possibility of hazard should be kept under constant review. Given the routine application of fetal ultrasound imaging, any possibility of deleterious developmental effects resulting from its use is an important public health issue. Rats have a well characterized central nervous system whose neurochemical pathways and neuronal electrophysiology qualitatively correspond to those of humans. Because of this, we opted to use Wistar rats as an animal model to document effects …

Economic Hardship And Children's Social Withdrawal In Romanian Families, Jennifer Denise Pearson

The sample consisted of 121 Romanian mothers and fathers of 4-5 year old children, as well as children's kindergarten teachers. Drawing on Conger and colleagues' family stress model of economic hardship, the associations among mothers' and fathers' ratings of economic hardship, depression, marital conflict, psychologically controlling parenting, and teacher ratings of child social withdrawal were analyzed. Structural equation modeling using AMOS 7.0 was used to test the model. Findings generally support earlier studies with European American families, as well as …

Stacked Generalization For Early Diagnosis Of Alzheimer's Disease, Hardik P. Gandhi

Theses and Dissertations

Alzheimer's disease (AD) is a neurological disorder characterized by nerve degeneration and neuronal death. The diagnosis of AD at an early stage is a major concern due to growing number of elderly people affected by the disease, as well as the lack of a standard diagnosis procedure available to community clinics. A biomarker that will allow early diagnosis of the disease would be beneficial. Such biomarker should be noninvasive, simple to obtain, safe, inexpensive, accurate, and most importantly, must be made available to local health clinics for maximum effectiveness.

Theses and Dissertations

In chapter 1, we describe development of a mild and efficient method for SNAr iodination of 6-chloropurine 2'-deoxynucleosides and nucleosides. Our studies demonstrate that 6-iodopurine nucleosides are excellent substrates for certain transition metal-catalyzed cross-coupling reactions. In chapter 2, we describe synthesis of protected 6-fluoro, 6-chloro, 6-bromo and 6-sulfonylpurine nucleosides. Comparisons among 6-fluoro-, 6-chloro-, 6-bromo, 6-iodo and 6-sulfonylpurine nucleosides for SNAr reactions with various N, O and S nucleophiles were investigated. Our results demonstrate that the 6-fluoropurine nucleoside is the best substrate for SNAr reactions among the four 6-halopurine nucleosides with oxygen, sulfur and aliphatic amine nucleophiles, and also with an …

An Infection Model For Examining The Effects Of Gender And Diabetic State On Proinflammatory Cytokine Secretion By Phagocytic Cells In Response To Infection With Burkholderia Pseudomallei, Laura L. Dickey

Theses and Dissertations

Burkholderia pseudomallei is an opportunistic soil pathogen that causes melioidosis, a life-threatening human disease prevalent in Southeast Asia, northern Australia, the Middle East, Africa, and South America. The organism also causes disease in plants and animals. Persons with severe melioidosis usually die of septicemia. Relatively little is known regarding the virulence mechanisms of B. pseudomallei; however, several putative virulence determinants have been identified. The organism is able to invade and replicate within phagocytic cells and is particularly pathogenic in males with diabetes mellitus. B. thailandensis is closely related to B. pseudomallei, but is not pathogenic. This study examines various in …

Biomass And Coal Fly Ash In Concrete: Strength, Durability, Microstructure, Quantitative Kinetics Of Pozzolanic Reaction And Alkali Silica Reaction Investigations., Shuangzhen Wang

Theses and Dissertations

Biomass represents an important sustainable energy resource, with biomass-coal cofiring representing among the most effective and cost efficient CO2 reduction strategies. Fly ash generated during coal combustion represents a technically advantageous, inexpensive, and environmentally beneficial admixture in concrete production, partially replacing cement. However, strict interpretation of American Society of Testing and Materials (ASTM) and American Concrete Institute (ACI) standards prohibits use of fly ashes from any source other than coal in concrete production; therefore, fly ash from biomass coal cofiring is excluded from use in concrete. This dissertation discusses biomass impacts on concrete properties through experiments conducted on several combinations …

Investigation Of Novel Microseparation Techniques, Yansheng Liu

Theses and Dissertations

Ultrahigh pressure liquid chromatography (UHPLC) makes it possible to use very small particles (< 2 µm) as packing materials to provide high column efficiencies. Results from a careful comparison of small porous and nonporous particles show that when the particle size is small enough (< 2 µm), both porous and nonporous particles give excellent performance, and the differences in column efficiencies between porous and nonporous particles become insignificant. Columns packed with bare diamond particles could separate small molecules, especially polar molecules, however, severe tailing occurred for less polar compounds. The polybutadiene coated diamond particles gave greater retention and better separation of small molecules compared to bare particles, although no improvement in column efficiency was observed. Changes in surface bonding of thermally hydrogenated diamond particles was achieved by chemical modification using various organic peroxides with or without reagents containing long carbon chain functional groups. It appears that the alkyl groups were attached onto the diamond surface with limited coverage. LC experiments did not demonstrate good separation; however, changes in LC behavior were observed. A repetitive solvent programming approach was successfully applied to the analysis of a continuous sample stream in microbore LC. Each analysis cycle consisted of three steps: pseudo-injection, elution and rinse. In the pseudo-injection step, elution with a non- or poor-eluting solvent produced a concentrated sample plug due to on-column focusing. Factors influencing peak symmetry, resolution and analysis cycle length were investigated. Quantitative analysis of a continuous sample stream is possible under certain operating conditions. Electric field gradient focusing (EFGF) devices with distributed resistor substrates could focus proteins in the separation channel, however, the focused bands were not stable, and the repeatability was poor due to the formation of bubbles and pH gradient in the separation channel. Both fiber-based and porous glass capillary-based planar EFGF devices with changing cross-sectional area (CCSA) channels were constructed and evaluated with the aid of a home-made scanning laser-induced fluorescence detection system. The fiber-based CCSA EFGF devices gave poorer performance compared with glass capillary based devices. Porous glass capillary-based EFGF devices could focus single proteins and separate mixtures of two to three proteins.

The Role Of Phosducin-Like Protein As A Co-Chaperone With The Cytosolic Chaperonin Complex In Assembly Of The G Protein Βγ Subunit Dimer, Paul Jayson Ludtke

Theses and Dissertations

Phosducin-like protein (PhLP) has been shown to interact with the cytosolic chaperonin containing TCP-1 (CCT), and the βγ subunit dimer of heterotrimeric G proteins (Gβγ). Here we provide details obtained from cryo-electron microscopic and biochemical studies on the structure of the complex between the cytosolic chaperonin CCT and PhLP. Binding of PhLP to CCT occurs through only one of the two chaperonin rings, making multiple contacts with CCT through both its N- and C-terminal domains. In addition, we show that PhLP acts as a co-chaperonin along with CCT in mediating the assembly of the G protein βγ subunit and that …

Pain Recall In Primary Dysmenorrhea, Robyn A. Drach

Optimizing Product Variant Placement To Satisfy Market Demand, Jonathan Roger Parkinson

Theses and Dissertations

Many companies use product families in order to offer product variants that appeal to different market segments while minimizing costs. Because the market demand is generally not uniform for all possible product variants, during the design phase a decision must be made as to which variants will be offered and how many. This thesis presents a new approach to solving this problem. The product is defined in terms of performance parameters. The market demand is captured in a preference model and applied to these parameters in order to represent the total potential market. The number and placement of the product …

Phosphorylation And Regulation Of The Dopamine Transporter By Psychostimulant Substrates And Protein -Protein Interactions, Mark A. Cervinski

Theses and Dissertations

The dopamine transporter (DAT) is an integral membrane protein that clears dopamine (DA) from the synaptic space following neurotransmission. DATs amino acid sequence contains numerous serine, threonine and tyrosine residues, some of which are located in protein kinase consensus sites. While DAT phosphorylation and regulation in response to protein kinase C activation is well documented, evidence suggests that multiple signals and interacting proteins also mediate these processes. Previous research has also demonstrated that DAT regulation is influenced by the presence of the DAT substrates amphetamine (AMPH), methamphetamine (METH) and the uptake blocker cocaine. Using 32PO4 metabolic labeling and [3H]DA uptake …

Optimism As A Buffer Against The Negative Impact Of Discrimination, Betsi Little

Theses and Dissertations

Research has shown that the general expectancy for positive outcomes, optimism, has been linked closely with the ability to positively cope with adverse life events, such as cancer, stress and depression. Being discriminated against has been shown to be a stressful event that has a negative psychological impact such as lowering self-esteem. Traits that have been linked with optimism, such as hardiness and self-efficacy have also been found to help combat the effects of discrimination among women. Although these traits implicate the role of optimism, to date, the possible effect of optimism itself as a buffer against the negative effects …

Decreased Renal Basement Membrane Thickening Is Accompanied By Elevated Renal Antioxidants In The Ames Dwarf Mouse Model Of Delayed Aging, Mandy M. Meyer

Theses and Dissertations

Experimental evidence suggests that disease- and age-related thickening of glomerular (GBM) and tubular (TBM) basement membranes may be related to increases in reactive oxygen species (ROS). Studies also suggest that antioxidants may function as renoprotectants against such ROS-induced damage. The current study focuses on metallothionein-I/II (MT-I/II) and glutathione (GSH), both of which exhibit potent antioxidant functions. Ames dwarf mice, which exhibit elevated tissue antioxidant levels (catalase, Cu/Zn superoxide dismutase, GSH) and an average life span significantly greater (50-65%) than wild type controls, were used to test our hypothesis that increased levels of renal MT-I/II and GSH are concomitant with decreased …

The Role Of Stat And The Jak/Stat Pathway In Mediating The Effects Of Interleukin-6 On Star Expression, Janae Strickland

Theses and Dissertations

Cortisol, a hormone produced by a hormone produced by the adrenal gland, is responsible for many regulatory functions in the body. Cortisol release is mediated by adrenocorticotrophic hormone, or ACTH, through the hypothalamus-pituitary-adrenal or HPA axis. This HPA axis is the major release pathway used during acute stress, during which the levels of ACTH parallel those of cortisol. However, in states of chronic stress, the level of ACTH drops dramatically, while cortisol remains high. This study focuses on the pathway of cortisol release during these chronic stress states, specifically examining the role of IL-6 with respect to STATs and the …

Manuscript No. 1 Recent research has indicated that low nest success and juvenile survival of Greater Sage-Grouse may be responsible for population declines. Recent technological advances in micro-transmitters have made radio-telemetry studies on Sage-Grouse chicks more common. Radio-telemetry enables monitoring of individual chicks and broods during a critical period of their life history. The exact cause of low chick recruitment in Strawberry Valley has not been well understood. In 2006, a chick mortality study using micro-transmitters was initiated to (1) determine the causes of chick mortality, (2) calculate overall chick survival, (3) compare chick survival in the Strawberry Valley population …

A Layered Social And Operational Network Analysis, Jennifer L. Geffre

Theses and Dissertations

To provide maximal disruption to a clandestine/terrorist network's ability to conduct missions, we must develop a means to determine the individuals' importance to the network and operations. In a network centric world, this importance is represented as an additive value of their criticality across the convergence of multiple layers of network connections. The connections layers of the network are comprised of social layers (Acquaintance, Friendship, Nuclear Family, Relatives, Student-Teacher, and Religious Mentors, Reverent Power and others), as well as layers representing interactions involving Resources, Knowledge/Skills and Temporal Local. The social criticality of an individual is measured by centrality. Event Trees …
