Staking Out The Territory : The University Of Western Australia, The Diploma In Education And Teacher Training 1914-1956, Kaye Tully, Clive Whitehead

Australian Journal of Teacher Education

The Diploma in Education has been a licence to teach in Western Australia since 1929. As an award made outside the State's education system, the history of the decision-making behind its institution has been overlooked. This article surveys some of the more important decisions made by The University of Western Australia as it staked out its territory in teacher education and training in the first half of the 20th Century. It suggests that the main motivation for such involvement by the University was to protect the quality of its matriculants, many of whom came from independent schools.

Recreational Opportunities And Health Status In West Virginia, Yoav Sneh

Graduate Theses, Dissertations, and Problem Reports (ETD)

Over half of all Americans are considered to be physically inactive and/or obese, leading to significant individual and societal costs. This study investigates the link between recreational supply and health status for West Virginia. Using spatial econometric techniques, this study provides solid evidence that the demand for health care is positively associated with physical inactivity rates, and that physical inactivity rates are inversely related to the supply of recreational opportunities. When promoting the importance of physical activity as preventative health care, policy makers should consider the provision of recreational opportunities as a means to overcome sedentary behaviors.

Characterization Of Wetland Soils In The Beaver Creek Watershed, Kyle Michael Stephens

Graduate Theses, Dissertations, and Problem Reports (ETD)

A proposed section of Appalachian Corridor H will pass through an area of the Beaver Creek watershed in Tucker County, West Virginia previously mined for the acid-producing Upper Freeport coal. Presently, partially-reclaimed spoils from past mining activities are generating acid mine drainage and releasing sediments into streams and other water bodies. Soils of acid mine drainage impacted wetlands and non-impacted wetlands were characterized to establish baseline soil status and to gain a better understanding of the chemical and physical processes occurring in these wetlands. The results of this study will be used to assist the West Virginia Division of Highways …

Cytogenetic Analysis Of Primary Breast Tumors And Mcf10a Cells To Determine Early Steps Of Breast Carcinoma, Mohammad Mah Odetallah

Graduate Theses, Dissertations, and Problem Reports (ETD)

Breast cancers are characterized by genomic instability, abnormal chromosomal counts and multiple translocations. There is a heavy burden on tumor cells to acquire as many mutations as possible in a short time. Tumors seem to achieve that through genomic instability. The role of homologous recombinational repair loss has been well established as a mechanism of chromosomal instability. A researcher at the University of Pittsburgh, Dr. Jean Latimer, was able to demonstrate the loss of nucleotide excision repair (NER), in adjacent non tumor tissue. NER functions in bulky adducts repair, following UV radiation. These lesions introduce a bend in the DNA …

Dietary Factors Influencing Iron Status Among Wic Participants Ages 6--24 Months, Marci Stayner Cannon

Graduate Theses, Dissertations, and Problem Reports (ETD)

Iron deficiency is a nationwide concern. Dietary strategies issued by national organizations, aim to help prevent childhood iron deficiency. This study examined the relationship of dietary factors with iron status in WIC participants 6--24 months. This was a cross-sectional study of 50 rural infants and toddlers.;Iron deficiency was determined from one blood sample analyzed for serum ferritin (SF) and transferrin saturation (TS). Iron deficiency was defined as SF ≤ 15 ug/dL and TS ≤ 15%. Two, 24-hour dietary recalls were collected. Stepwise logistic regression was used to evaluate factors predictive of iron status.;Thirteen children (26%) were iron deficient. Iron status …

Uterine Uptake Of Diazepam And Quantification By Gas Chromatography/Mass Spectrometry, Steven Scott Wolfe

Graduate Theses, Dissertations, and Problem Reports (ETD)

One of the difficulties in drug delivery is transporting the compound of interest to the target organ while minimizing exposure to the rest of the body. Intravenous administration is effective in the delivery of drugs and results in high bioavailability leading to very rapid systemic distribution. Oral dosing of drugs is the most popular route because of its ease of administration, but it is subject to first pass metabolism by the liver which can greatly reduce the bioavailability of the parent compound. Patients undergoing hysterectomy were recruited for a study in which they were anesthetized and 5 mg of diazepam …

Molecular Mechanisms Of G Protein-Receptor Coupling, Janna Eugenievna Slessareva

Graduate Theses, Dissertations, and Problem Reports (ETD)

A big diversity in heterotrimeric G proteins and their cognate receptors raises many questions about the mechanisms that regulate the specificity of signaling along G protein-mediated pathways. The major goal of this project was to understand how the selectivity of G protein-receptor coupling is achieved at the level of the G protein-receptor interface. Additional goals of this project were to assess the generality of molecular mechanisms controlling G protein-receptor coupling selectivity and to investigate how agonist may regulate G protein-receptor interactions. Molecular determinants of G protein-receptor coupling were studied by reconstitution of exogenously supplied, purified G protein heterotrimers with receptors …

Economics Of Breast Cancer Preventive Strategies In A Medicaid Program, Rohit D. Borker

Graduate Theses, Dissertations, and Problem Reports (ETD)

The primary objective of the study was to estimate the long-term benefits and costs of chemopreventive tamoxifen and mammography screening in women who are otherwise healthy but at high risk of developing breast cancer. Three hypothetical cohorts of high-risk women were initiated at age forty. The first cohort consumed chemopreventive tamoxifen and underwent routine mammography screening. The second cohort also consumed chemopreventive tamoxifen but underwent mammography screening at real-world rates. The third cohort (control cohort) did not consume chemopreventive tamoxifen and underwent mammography screening at real-world rates. The study also assessed the proportion of women in the West Virginia Medicaid …

The Journey Of Education: Characteristics Of Shoshone-Bannock High School And Community Members On The Fort Hall Indian Reservation, Ed Galindo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation examined personal, cultural, school, and family factors that contribute to the decision of Native American students to remain in school until graduation or to drop out. One hundred eighty-one participants who had either graduated or dropped out of school completed a 140-item questionnaire. Participants lived on the Shoshone-Bannock Indian Reservation located at Fort Hall, Idaho.

Factors examined in the survey instrument included substance abuse by self or family members, peer pressure, trouble with the law, self-esteem, teen pregnancy, family structure, socioeconomic status, parents education, academic achievement, teacher attitudes and expectations, school attendance, tribal self-identity and pride, and bilingualism. …

Using Immune Modulators To Ameliorate Aleutian Disease In Mink, Kie Hoon Jung

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Aleutian disease of mink (AD) is an immunopathological disorder induced by persistent infection with AD virus. Many breeds of mink seem to have a high susceptibility to AD. Interestingly, the primary feature of AD in susceptible adult mink is a chronic, fatal immune complex-mediated glomerulonephritis comparable to that seen in human diseases such as systemic lupus erythematosus. Because of its comparative aspects to human diseases and the substantial economic loss to the fur industries in the world, classical AD and the nature of the virus has been studied extensively for three decades. Currently no therapies are available and vaccination has …

Prospects For Biological Control Of The Western Flower Thrips, Frankliniella Occidentalis, With The Entomopathogenic Fungus, Metarhizium Anisopliae, On Chrysanthemum, N. K. Maniania, S. Ekesi, B. Löhr, F. Mwangi

All Peer-Reviewed Publications

The potential of Metarhizium anisopliae (Metsch.) Sorok. for the control of Frankliniella occidentalis (Pergande) on chrysanthemum cuttings was evaluated in greenhouse experiments. The fungus significantly reduced both the adult and larval populations of F. occidentalis, although the level of control of larval populations was much lower than for adults. Combined application of M. anisopliae and Methomyl (Lannate®), however, resulted in a significant reduction of both the larval and adult stages. The use of both control agents might be helpful in reducing the selection pressure for resistance to chemical insecticides, thereby delaying or preventing the build-up of resistant populations in greenhouses.

The Capacity To Form H-Dna Cannot Substitute For Gaga Factor Binding To A (Ct)N*(Ga)N Regulatory Site, Quinn Lu, John Teare, Howard Granok, Marci Swede, Jenny Xu, Sarah C.R. Elgin

Biology Faculty Research

Previous studies of the Drosophila melanogaster hsp26 gene promoter have demonstrated the importance of a homopurine*homopyrimidine segment [primarily (CT)n*(GA)n] for chromatin structure formation and gene activation. (CT)n regions are known to bind GAGA factor, a dominant enhancer of PEV thought to play a role in generating an accessible chromatin structure. The (CT)n region can also form an H-DNA structure in vitro under acidic pH and negative supercoiling; a detailed map of that structure is reported here. To test whether the (CT)n sequence can function through H-DNA in vivo, we have analyzed a series of hsp26-lacZ transgenes with altered sequences in …

An Ecological/Life History Comparison Of Two Whitefish Species In Bear Lake, Utah/Idaho, Brett W. Thompson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ecological traits of the endemic Bear Lake whitefish Prosoopium abyssicola and the Bonneville whitefish prosopium silonotus were investigated. Spatial distributions indicated distinctive differences in depth contour preference. Catch per unit effort data indicated that Bonneville whitefish prefer shallow depths and warmer water temperatures, whereas Bear Lake whitefish prefer deep, cold water.

Diet differences between the two species were large. Differences in both age distribution and growth rate patterns were also observed. The Bonneville whitefish population was predominantly composed of juvenile age classes. Very large adults reached ages of 12-14 years. Bear Lake whitefish exhibited a different population structure with few …

Assessing The Effects Of Myxobolus Cerebralis And Other Environmental Factors On The Dynamics, Abundance, And Distribution Of Trout Populations In The Logan River, Utah, Ernesto A. De La Hoz Franco

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The presence of nonnative trout and the recent introduction of Myxobolus cerebralis in the Logan River drainage pose a threat to the native Bonneville cutthroat trout population (Oncorhynchus clarki Utah). The variability in the response of susceptible trout populations to M. cerebralis, causing agent of whirling disease, suggests that environmental factors may influence the effects of the parasite in infected environments. I investigated the relationship between temperature, discharge, substrate size, nutrient concentration (nitrogen and phosphorus), periphyton (chlorophyll a), and the relative abundance of Tubifex tubifex to the distribution, and prevalence of M. cerebralis in wild salmonid populations and …

Factors Affecting Spawning And Survival Of Bear Lake Bonneville Cutthroat Trout In St. Charles Creek, Idaho, Paul Burnett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I described the spawning ecology of the Bear Lake Bonneville cutthroat trout (BLBCT) in St. Charles Creek. I tracked cutthroat trout with used radio telemetry. I conducted redd counts to describe spawning conditions. Most cutthroat trout in the Big Arm strayed into the Bear River. Cutthroat trout migrations in the Little Arm and main fork were very limited (< 4 km). Redd distributions showed very similar patterns between 1989, 2000 and 2001 with most redds being built in the lowest kilometer of stream. Artificial fish transportation changed the redd distribution in 2002. More redds were built in the main fork and redds were distributed throughout the stream. Redds built in the main fork were characterized by lower levels of fine sediment and higher water velocities as compared to the redds built on the Little Arm. The results of this research will be used to aid resource managers in developing a management plan for wild BLBCT.

Determining The Factors That Control Respiration And Carbon Use Efficiency In Crop Plants, Jonathan M. Frantz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the literature on plant respiration, there are two viewpoints concerning the source of respiratory control: supply (photosynthate availability) or demand (temperature dependent) limitations. While different studies indicate the primary dependency for respiration is either the supply or demand side, the two paradigms cannot both be true. The relative importance of each paradigm may depend on a number of factors including period of time during which respiration is measured, phase of plant development, environmental conditions, and species.

Studies were performed using continuous CO₂ gas-exchange instrumentation to monitor short- and long-term changes in whole canopies of lettuce, tomato, soybean, and …

Breeding Bird Communities Of Major Mainland Rivers Of Southeastern Alaska, Jim A. Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Because of the scarcity of information for bird communities at the major mainland rivers of southeastern Alaska, the main objective of this study was to provide baseline information including distribution, status, and habitat associations of breeding birds.

I conducted a meta-analysis of all known reports (including the current study) conducted at major mainland rivers during the breeding season. I described bird species composition, distribution, abundance estimates, status, habitat associations, and guild membership for all birds recorded at 11 major mainland rivers. Based on incidental observations, 170 species were recorded by all studies. Of these, 134 species were known or suspected …

Chinese Parents’ Knowledge, Attitudes, And Practices About Sexuality Education For Adolescents In The Family, Wenli Liu, Carolyn P. Edwards

Department of Child, Youth, and Family Studies: Faculty Publications

This study used a cross-sectional, multi-site survey design to examine Chinese parents’ knowledge, attitudes, and practices in the area of sexuality education for adolescents. Three cities in China were selected for the survey, and the final sample contained 841 parents with children ranged from 11 to 19 years. The majority of Chinese parents were found to have reasonably accurate knowledge about sexuality and positive attitudes toward sexuality and sexuality education. However, most Chinese parents reported that they never talked with their children about sexuality. Parental education was strongly related to both knowledge and attitudes. Gender of parent was a significant …

The Foraging Behavior Of A Solitary Bee, Diadasia Nigrifrons (Hymenoptera: Anthophoridae) On Sidalcea Oregana, Ssp. Oregana, Kimberly A. Kuta

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Foraging studies have established that bees typically obey a set of movement rules when foraging on vertical inflorescences: they begin foraging at the bottom of an inflorescence, move upward, visit a fraction of the available flowers, and leave before reaching the top of the inflorescence. These behaviors are purported to maximize bee foraging efficiency by concentrating their efforts on the most rewarding flowers and minimizing flower revisits. Bees also increase their efficiency by selecting inflorescences with many flowers, visiting more flowers per inflorescence, and remaining in resource-rich areas. To test these hypotheses on plants with more complicated flower arrangements, I …

Simulation Of Wind Dispersal Of Tree Seeds, Tree Colonization, And Growth Of Bottomland Hardwood Reforestation Sites Of The Mississippi Alluvial Valley, Timothy James Nuttle

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Tree community composition in bottomland hardwood reforestation sites is considerably less diverse than natural bottomland hardwood forests. This study sought to understand the mechanisms behind failure to develop diverse tree communities. First, I developed a mechanistic model of seed dispersal by wind in spatially variable environments. Second, I developed a spatially explicit simulation model of forest dynamics that includes this wind-dispersal model to investigate whether diversity is limited by dispersal or interactions among species and individuals. Finally, I performed model experiments to determine if manipulations of stand structure might help improve conditions for colonization of various species, thus enhancing diversity …

Species Pairwise Associations Over Nine Years Of Secondary Succession: Assessing Alternative Explanations And Successional Mechanisms, Lara R. Rozzell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The importance and mechanisms of species interactions are undetermined in most successional systems. I used correlations and null modeling to detect pairwise species associations between 33 plant species in the first nine years of secondary succession after logging and burning in a western Oregon Cascade forest. I tested for correlations between each species and soil nutrients, nonvegetative ground cover, and surrounding vegetation. More positive than negative associations were found at all sampling times. The proportion of positive associations decreased and negative associations increased through time. Up to 42% of associations at a sampling time were explicable by shared positive correlations …

Quaternary Geology And Landscape Evolution Of Eastern Grand Canyon, Arizona, Matt D. Anders

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Tectonics and drainage evolution are controlling overall landscape incision in eastern Grand Canyon. Superimposed on downcutting are dynamic responses of hillslopes, tributary streams, and the Colorado River to glacial-interglacial climate cycles. Five tributary stream fill terraces have been identified, and luminescence dating indicates aggradation was occurring 50- 34 ka {S3), 12-7 ka (S2), and 5-3.5 ka (S1). Seven Colorado River fill terraces have been identified, and luminescence and U-series dating indicate deposition was occurring 343-322 ka (M5), 151-118 ka (M4), and 71-64 ka (M3).

Aggradation by the Colorado River in eastern Grand Canyon begins during glacial advances and continues into …

Foraging Behavior And Habitat Use Patterns Of Brown Bears (Ursus Arctos) In Relation To Human Activity And Salmon Abundance On A Coastal Alaskan Salmon Stream, Anthony P. Crupi Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Over the past decade, demand for recreation has increased as part of Alaska's doubling growth in tourism. Along the Chilkoot River, near Haines, fishing and bear viewing have become increasingly popular. I investigated the ecological and behavioral interactions there between brown bears, salmon, and humans between 2000 and 2002. My objectives were to: (1) determine if specific human activities differentially influenced bear activity and foraging behavior, (2) identify temporal and spatial habitat use patterns, (3) evaluate brown bear response to natural and human disturbances and quantify related flight distances, (4) investigate changes in bear foraging behaviors in response to prey …

Restoration Of Aspen In Different Stages Of Mortality In Southern Utah, Seth Ray Ohms

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Aspen clones of an aspen-dominated community in Southwestern Utah are declining, some having experienced high mortality coupled with in sufficient regeneration. The objectives of this study were to (I) determine if decadent, non-regenerating mature aspen stands could be regenerated through disturbance of the 111 auxin/cytokinin hormone relationship by clearcutting; (2) determine the extent of ungulate use of regenerating aspen ramets. Clearcuts were made in late summer of 2001 in 10 different clones that exhibited various levels of decline on a continuum from relatively healthy to extremely deteriorated. Nested wildlife/livestock exclosures were constructed in each clearcut plot, as well as in …

Rapid Detection Of Listeria Monocytogenes, Wim Lippens

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Listeria monocytogenes is a foodbome pathogen that can cause severe illness and even death. It is found in dairy and meat products. The focus is on rapid detection since conventional methods are time consuming (4-5 days). Pre-enrichment steps, as part of those methods, are time consuming. Our objective was to develop a detection system without a pre-enrichment step, giving a final result within 2 to 4 h.

In the concept of "the need for speed," a detection system with an antibody-based capture technique, followed by polymerase chain reaction (PCR), was developed. Glass beads coated with a Listeria polyclonal antibody were …

Rapid Effects Of 25-Hydroxyvitamin D3 On Calcium Uptake In Isolated Chick Enterocytes, Ruta Phadnis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

25-Hydroxyvitamin D₃[25(OH)D₃] is a metabolite of vitamin D₃ that has long been considered to be an inactive precursor of the hormonally active metabolite 1,25- dihydroxyvitamin D₃[l,25(OH)₂D₃]; consequently very few studies have addressed the potential biological activity of 25(OH)₂D₃. However, it is known that 100 nM 25(OH)₂D₃ increases calcium transport in the perfused duodenal loop of the chicken to 200% of controls within 20 minutes. The hypothesis of the current study is that 25(OH)₂D₃ may be a hormonally active metabolite …

Determining The Influence Of The Extracellular Proteinase From Brevibacterium Linens On The Metabolism Of Lactococcus Lactis Spp. Lactis Using Functional Genomics, Yi Xie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the catabolism of amino acids in cheese results in the formation of most volatile flavor compounds, a proper intracellular pool of amino acids must be established in order to produce a desirable flavor production in cheese. Generation of this pool of amino acids requires complex interactions among casein and its derivatives, proteolytic enzymes, and transport systems in the associated bacteria, including lactococci. In this project, we hypothesized that casein hydrolysis by the extracellular proteinases of Brevibacterium linens BL2 modulates the expression profile of proteolytic related genes in Lactococcus lactis spp. lactis IL1403.

In order to monitor the …

Effect Of Drought, Flooding, And Potassium Stress On The Quantity And Composition Of Root Exudates In Axenic Culture, Amelia Henry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Root exudates include important chelating compounds and can change the rhizosphere pH by several units. These changes are essential for nutrient uptake and can also alter solubility of soil contaminants and increase plant uptake. Mild root-zone stress may increase exudation and more severe stress can damage membranes and increase root turnover, all of which increase root-zone carbon. Increased carbon from this rhizodeposition can increase microbial activity, which might help degrade contaminants. We studied the effect of three types of stress on root exudation of crested wheatgrass (Agropyron cristatum): low K⁺, drought, and flooding. These stresses were …

Short-Term Water Use Dynamics In Drainage Lysimeters, Musa V. Dlamini

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Turfgrass water use (seasonal turfET) and crop coefficients were determined and a mathematical soil-water balance model for non-weighing drainage lysimetcrs, which simulates the occurrence (timing and amount) of drainage, was developed. Pairs of non-weighing drainage lysimeters were used to determine crop coefficients for turfgrass in four locations in the state of Utah: Logan Golf and Country Club, Murray Golf Course, Brigham Young University (Spanish Fork) Experiment Farm, and Sunbrook Golf Course (St. George).

Daily weather data including air temperature, relative humidity, average wind travel, total solar radiation, precipitation, and average soil temperature were collected with an electronic weather station at …
