All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
On September 10, 2005, a landslide occurred to the south of Utah State University Campus and Highway 89. This landslide did considerable damage to the Logan and Northern canal, which is cut into the slope, and to a residence at the toe of the slope. This event brought many parties together to collaborate on possible solutions to the immediate fix of the slide as well slides that could occur in the future. The purpose of this report is to compile information useful to the study of the area and the possible solutions and/or risk assessment of the Logan Bluff Landslide …
The Relative Effects Of Education And Cognitive Complexity Of Employment Experience On The Rate Of Cognitive Decline In Elderly Women, Janet M. Lundahl
The Relative Effects Of Education And Cognitive Complexity Of Employment Experience On The Rate Of Cognitive Decline In Elderly Women, Janet M. Lundahl
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This thesis examined the lifetime exposure of women's employment on cognitive functioning and cognitive decline in late life.
From the Cache County Study on Memory, Health, & Aging data, a sample of 2,588 women, aged 65 and older gave retrospective occupational history and were screened using the Modified Mini-Mental State Exam at study entry and approximately 3 years later. Non-demented women were used.
Ordinary least squares regression was used cross-sectionally and longitudinally to test the association between cognitive complexity level of the longest job and baseline cognitive status, and rate of cognitive decline over approximately 3 years.
Cross-sectional analysis revealed …

The Contribution Of Environmental Variables On Small Mammal Species Richness And Relative Abundance In Eastern Nevada, Stephanie Harris
UNLV Theses, Dissertations, Professional Papers, and Capstones
The purpose of this study is to determine how four environmental variables: elevation, latitude, soil type, and vegetation impact the relative abundance of Peromyscus maniculatus and the species richness of small mammal populations in Eastern Nevada. In order to complete this study, a survey of small mammals was completed in the following 8 Eastern Nevada valleys: Delamar, Dry Lake, Dry Lake- Muleshoe,Cave, Lake, Snake, Spring, White River. In each valley, transects of Sherman live traps will be set up for 3 consecutive nights (O'Farrell et al 1977). Data on elevation, latitude, soil type, and vegetation were taken at each trap …
The Fate And Transport Of Nitrogen (N) And The Effect Of Emergent Plants On Natural Treatment Of N-Species At Las Vegas Wash, Nevada, Tanju Kiriscioglu
The Fate And Transport Of Nitrogen (N) And The Effect Of Emergent Plants On Natural Treatment Of N-Species At Las Vegas Wash, Nevada, Tanju Kiriscioglu
UNLV Theses, Dissertations, Professional Papers, and Capstones
The purpose of this study is to analyze the effect of emergent plant communities at Las Vegas Wash (the System) using a system dynamics modeling approach. Understanding the dynamics of nitrogen (N —major polluting nutrient in the Wash) that enters the System is important because it occasionally causes algal blooms, choking Lake Mead through excessive eutrophication. Emergent plant communities are an integral part of wetland ecosystems and they play a crucial role in natural treatment of nutrients. This study is intended to test this hypothesis.
The study makes use of Wash data from reliable sources (Las Vegas Valley Water District, …

Vittatispora, A New Melanosporaceous Genus From Indian Soil, Preeti Chaudhary, Jinx Campbell, David L. Hawksworth, Kedarnath N. Sastry
Faculty Publications
Vittatispora coorgii gen. sp. nov., isolated from soil in India, is described and illustrated. The fungus has morphological characteristics of the genera Melanospora, Sphaerodes and Syspastospora. The most striking feature is the presence of a thick hyaline ridge along the vertical axis of the lemonshaped ascospores wall. Perithecia also have a long neck composed of adhering hyphae, similar to that of Syspatospora. Phylogenetic studies on the 28S rDNA indicate it is closely related to Melanospora and Sphaerodes and belongs in the Ceratostomataceae. The new genus is based on the distinctive morphology and phylogenetic analyses. The fungus grew in culture only …
Phylogeny And Androecial Evolution In Schisandraceae, Inferred From Sequences Of Nuclear Ribosomal Dna Its And Chloroplast Dna TrnL-F Regions, Zhong Liu, Gang Hao, Yi-Bo Luo, Leonard B. Thien, Samuel W. Rosso, An-Ming Lu, Zhi-Duan Chen
Phylogeny And Androecial Evolution In Schisandraceae, Inferred From Sequences Of Nuclear Ribosomal Dna Its And Chloroplast Dna TrnL-F Regions, Zhong Liu, Gang Hao, Yi-Bo Luo, Leonard B. Thien, Samuel W. Rosso, An-Ming Lu, Zhi-Duan Chen
Faculty Publications
Sequences of nuclear ribosomal DNA ITS and chloroplast trnL‐F regions were used to construct a phylogeny of Schisandraceae. The results show that there are two major clades in Schisandraceae. One is composed entirely of Schisandra species; the other contains a mixture of Schisandra and Kadsura species. Molecular data place Smith’s sect. Sphaerostema of Schisandra prominently within Kadsura, and thus neither Schisandra nor Kadsura is monophyletic, refuting the traditional division of the family into two genera based on morphological characters of mature fruits. The sister relationship between S. glabra (North America) and S. bicolor (China) and the monophyly of …

Towards A More Comprehensive View Of The Use Of Power Between Couple Members In Adolescent Romantic Relationships, Charles George Bentley
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study investigated the construct of power in adolescent romantic couples using multiple measures. The project examined gender differences in power, created models of powerlessness for each gender, and examined relations between power and aggression and relationship quality. Participants were 90 heterosexual couples, aged 14-18 years old, living in rural areas in Utah and Arizona. Couple members completed surveys assessing attitudes and behaviors in their relationships and a video-recall procedure in which partners rated their own and their partner's behaviors during problem solving discussion.
Few gender differences emerged in reports of perpetration of aggression, but boyfriends reported higher levels of …

The Unknown Struggle : A Comparative Analysis Of Women In The Black Power Movement., Elizabeth Michele Jones
Electronic Theses and Dissertations
This thesis comparatively analyzes the experiences and roles of women in the United States and Caribbean Black Power Movements. Using the Black Panther Party and Trinidadian National Joint Action Committee as case studies, the researcher isolates similarities and differences among women in these two regions of the African Diaspora. Black Feminist and Caribbean Feminist theoretical perspectives aide in understanding how the interlocking social forces of race, class, and gender impacted women participating in the Black Nationalist movement of the late 1960's and early 1970's.

Current fishing practices are regarded as unsustainable (Pauly et al. 2002), yet our appetite for seafood grows. To meet the growing gap, there are increasing calls for mankind to tame the oceans through aquaculture (Marra 2005). Close to the coast, rapid expansion of marine aquaculture is underway throughout the world. Sea cages enclose 2.5 million tons of fish, while 12 million tons of mussels, oysters and clams hang from floating ropes or grow on racks or trays (FAO 2004). Aquaculture structures are now ubiquitous to many coastlines. As the expansion continues, how can we best manage the interaction between natural …
Site Directed Gene Disruption Of Rpfa In Xylella Fastidiosa : Non-Biofilm Producing Mutants As An Approach To Eradication Of Pierce's Disease In Grapevine, Janice Diane Thomas
Site Directed Gene Disruption Of Rpfa In Xylella Fastidiosa : Non-Biofilm Producing Mutants As An Approach To Eradication Of Pierce's Disease In Grapevine, Janice Diane Thomas
Theses, Dissertations and Culminating Projects
Xylella fastidious a, a gram-negative, rod shaped bacterium, causes disease in many economically important plants including citrus, coffee, and grapevine. Xylella fastidiosa is xylem limited and is dependent on insect vectors for transmission. Pierce’s Disease of Vitis vinifere grape, transmitted by an insect vector, poses a serious threat to California vineyards today. The glassy-winged sharp-shooter, Homalodisca coagulata, has caused millions of dollars of damage to the California wine industry in just a few years. There is evidence that Xylella fastidiosa may share the molecular mechanisms through which the bacterium establishes infection with a closely related species, Xanthomonas campestris. A cluster …
Needing To Act: Exploring Deliberate Self-Harm In Incarcerated Women, Jacqueline Mangnall
Needing To Act: Exploring Deliberate Self-Harm In Incarcerated Women, Jacqueline Mangnall
Theses and Dissertations
Deliberate self-harm (DSH), behavior that causes minor to moderate physical injury that is undertaken without conscious suicidal intent, is a frequent behavior in institutions such as prisons. The purpose of this study was to develop a grounded theory of DSH in incarcerated women. Seven incarcerated women who self-harm were interviewed and constant comparative analysis techniques were used to develop a model of DSH in incarcerated women. The model of Needing to Act emerged from the data of this study. Adverse childhood and adult events, such as sexual and physical abuse, were the predisposing factors for both acting out (criminal offending) …
Ret Dependent Changes In Gene Expression, Christian Anne Burr
Ret Dependent Changes In Gene Expression, Christian Anne Burr
Theses, Dissertations and Culminating Projects
RET is a mammalian receptor tyrosine kinase required for proper kidney and neuronal development. RET is expressed as three splice variants named RET9, RET43 and RET51 based on the splice variations at the 3’ end of the gene. All three splice variants of RET are activated by a complex of proteins including a ligand (GFL) and a co-receptor (GFR[alpha]l-4). Although there has been a great deal of work looking at the early stages of RET activation, less is known about the long-term effects, including transcriptional changes that occur in response to RET activation. In this study, transcriptional changes following RET …
The Effects Of Music On Art Making With Older Adults, Gertrude W. Goodwin
The Effects Of Music On Art Making With Older Adults, Gertrude W. Goodwin
EVMS School of Health Professions Theses & Dissertations
It is projected that by 2030, older adults will make up 69.4 million of the population in the United States (U.S. Bureau of the Census, 2001). The basic physical, mental, and emotional needs of these older adults must be addressed to ensure an adequate quality of life. Quality of life refers to the degree needs are being met as well as the person’s perception and satisfaction with life. As the population ages there is an increased expectation for a higher quality of life because older adults are healthier, more active, and living longer. The therapeutic use of art and music …

Art Therapy And Sensory Stimulation To Decrease Agitation: A Pilot Study, Leslie Cristen Lavergne
EVMS School of Health Professions Theses & Dissertations
Dementia affects 1% of older adults in America between the ages of 65 and 74 years, and increases to 10% in those 85 years and older. The cognitive and behavioral symptoms of dementia may restrict an individuals ability to perform activities of daily living, such as self-care, memory, and language. The literature supports the premise that individuals who have dementia can benefit from a treatment approach that focuses on medication regulation, as well as mental stimulation. This study was an art therapy and sensory stimulation intervention designed to reduce agitation, a common non-cognitive symptom of dementia. This study included five …

Mechanisms Underlying The Sperm Quality Advantage In Sperm Competition And Cryptic Female Choice In Drosophila Melanogaster, James Pattarini, William T. Starmer, Adam Bjork, Scott Pitnick
Mechanisms Underlying The Sperm Quality Advantage In Sperm Competition And Cryptic Female Choice In Drosophila Melanogaster, James Pattarini, William T. Starmer, Adam Bjork, Scott Pitnick
Renée Crown University Honors Thesis Projects - All
Contrary to early predictions of sperm competition theory, postcopulatory sexual selection favoring increased investment per sperm (e.g., sperm size, sperm quality) has been demonstrated in numerous organisms. Recent findings reveal that sperm production strategies are highly variable, with males of some species producing relatively few, giant sperm. We empirically demonstrate for Drosophila melanogaster that both sperm quality and sperm quantity independently contribute to competitive male fertilization success. The interaction between sperm quality and quantity suggests an internal positive reinforcement on selection for sperm quality, with selection predicted to intensify as investment per sperm increases and the number of sperm competing …
Ventilator Induced Lung Injury, John A. Johnson Jr.
Ventilator Induced Lung Injury, John A. Johnson Jr.
Renée Crown University Honors Thesis Projects - All
Severe physical-trauma can lead to the development of acute respiratory distress syndrome (ARDS). Currently, the only known treatment for ARDS is mechanical ventilation. However, if mechanical ventilation is applied inappropriately further injury and malfunction of the lungs may occur, and thus, causing a ventilator induced lung injury (VILI). VILI has several manifestations including volutrauma, atelectrauma, and biotrauma. These mechanisms often exacerbate one another adding further insult to the injury. The goal of this current study is to establish a stable control pig model of ARDS as a comparison for ventilatory strategies that will act in a more protective manner than …
Filthy Clean Advertisements: A Comparative Study Of Shampoo Advertisements From 1954 And 2004, Jacqueline Braun
Filthy Clean Advertisements: A Comparative Study Of Shampoo Advertisements From 1954 And 2004, Jacqueline Braun
Renée Crown University Honors Thesis Projects - All
In this study, national advertisements for shampoo products were compared from 1954 and 2004 through the utilization of Katherine Toland Frith’s “Undressing the Ad” technique. This analysis procedure measures the underlying meaning of an advertisement through the dissection of the surface, intended, and cultural/ideological meaning. This study used 10 advertisements, five from each respective decade, to measure each advertisement’s level of stereotyping toward females and gender stereotyping cultivation in general. The study revealed that the 1954 advertisements more directly projected gender stereotyping; however, the 2004 advertisements also contained the stereotypes on an indirect level. Additionally, the analysis uncovered the fact …

Mouse and human natural killer T (NKT) cells recognize a restricted set of glycosphingolipids presented by CD1d molecules, including self iGb3 and microbial alpha-glycuronosylceramides. The importance of the canonical Valpha 14-Jalpha18 TCR alphachain for antigen recognition by NKT cells is well recognized, but the mechanisms underlying the Vbeta8, Vbeta7, and Vbeta2 bias in mouse have not been explored. To study the influences of thymic selection and the constraints of pairing with Valpha 14-Jalpha 18, we have created a population of mature T cells expressing Valpha 14-Jalpha 18 TCRalpha chain in CD1d-deficient mice and studied its recognition properties in vitro and …
Survey Of Reproduction Of The Southeastern American Kestrel (Falco Sparverius Paulus) In Electrical Transmission Towers In South-Central Georgia, Pamela Lynn Maney
Survey Of Reproduction Of The Southeastern American Kestrel (Falco Sparverius Paulus) In Electrical Transmission Towers In South-Central Georgia, Pamela Lynn Maney
College of Graduate Studies: Theses & Dissertations
This study involved a survey of the distribution and the reproductive biology of the rare southeastern subspecies of the American kestrel, Falco sparverius paulus, which was found to be breeding in the hollow cross-arms of the 230 kV electrical transmission towers between the Offerman substation in the east, to Plant Mitchell (Putney), in the west, in south-central Georgia. This subspecies of the kestrel has declined in the southeastern United States by more than 80% over the last fifty years, and populations of F.S. Paulus have nearly disappeared below the Fall Line in Georgia. The major factor contributing to this decline …
Age Effects On Social And Investigative Behaviors In A Closed Population Of African Elephants, Christen Eileen Merte
Age Effects On Social And Investigative Behaviors In A Closed Population Of African Elephants, Christen Eileen Merte
College of Graduate Studies: Theses & Dissertations
In this study of African elephants (Loxodonta africana), I examined two competing hypotheses to explain the development of social and reproductive behaviors. The reproductive hypothesis states that behaviors change around the time when an individual begins successfully reproducing, while the social dominance hypothesis states that behaviors change throughout the life of an individual, reflective of changes in social rank. These hypotheses were explored in male and female elephants during the entry to a signal-rich waterhole and in female African elephants across seasons. Chemosensory and social behaviors were recorded in Addo Elephant National Park between May 2004 and June 2005 using …
Population Genetic Structure Of The Temperate Scleractinian Coral, Oculina Arbuscula, In Coastal Georgia, Lauren Michelle Wagner
Population Genetic Structure Of The Temperate Scleractinian Coral, Oculina Arbuscula, In Coastal Georgia, Lauren Michelle Wagner
College of Graduate Studies: Theses & Dissertations
Dispersal of marine organisms has generally been assumed to be demographically open with planktonic larvae exploiting ocean currents to travel long distances. However, recent studies report evidence of local larval recruitment. In this study, I hypothesized that populations of the temperate coral, Oculina arbuscula, are maintained primarily by local recruitment off the Georgia coast because: 1) suitable substrate for settlement is patchy and 2) O. arbuscula's branching morphology is conducive to asexual reproduction by fragmentation. To address this hypothesis, I combined data from allozyme electrophoresis, histocompatibility assays, and despersion of established colonies. Results indicated substantial local recruitment maintained primarily by …
Local Adaptation For Life-History Traits In Silene Latifolia, Brandy May Penna
Local Adaptation For Life-History Traits In Silene Latifolia, Brandy May Penna
College of Graduate Studies: Theses & Dissertations
A fundamental question in evolutionary ecology is how species adjust post colonization. The plant Silene latifolia was introduced to North America (NA) from Europe (EU) in the 1800s. The goal of this thesis was to test if Silene latifolia has become locally adapted across its range. My first experiment tested local adaptation of germination success to three temperatures across three latitudinal regions in a growth chamber using seeds from nine EU and NA populations. Germination success or speed was similar among latitudinal regions across continents. My second experiment examined local adaptation at a continental scale; I grew plants from 15 …
Molecular Pathogenesis Of Legionella Longbeachae., Rexford Asare 1972-
Molecular Pathogenesis Of Legionella Longbeachae., Rexford Asare 1972-
Electronic Theses and Dissertations
The ability of L. pneumophila to cause disease depends on its replication in alveolar macrophages. Infectivity and the expression of various virulence traits is triggered at post exponential growth phase. We show that unlike quiescent macrophages, L. longbeachae does not replicate in IFN-ã activated macrophages and its intracellular replication is independent of the growth phase of the inocula. L. pneumophila replicates in a phagosome that excludes early and late endocytic markers, and is surrounded by the rough endoplasmic reticulum (RER). In contrast, the L. longbeachae phagosome colocalizes with early endosomal marker EEA1, late endosomal markers LAMP-2 and M6PR, and ER …
Influence Of Human Papillomavirus 16 E6 On Trail-Mediated Apoptosis, Theodore O. Garnett
Influence Of Human Papillomavirus 16 E6 On Trail-Mediated Apoptosis, Theodore O. Garnett
Loma Linda University Electronic Theses, Dissertations & Projects
Viruses have developed sophisticated strategies to evade host defenses and facilitate the production and spread of progeny. HPV 16, whose immune evasion activities can contribute to cervical cancer, is a prime example of such a virus. In this study, we examined the influence of HPV 16 E6 on TRAIL-induced FADD-dependent and -independent pathways in two cellular models: HCT116 colon carcinoma cells and U2OS osteosarcoma cells. We show that transfection of the HPV 16 E6 oncogene into HCT116 cells provides protection from TRAIL-mediated apoptosis. Additionally, we demonstrate that the protection provided by E6 is dose-dependent because higher levels of E6 provide …
