Ways In Which Community Involvement May Influence Girls’ Education In Senegal, Babou Ndiaye

Masters Theses

This study attempts to examine through the lens of social feminist theory the ways in which community involvement may influence girls’ education in Senegal. It highlights the extent to which networking, advocacy, and meaningful interactions between community and school may contribute to improving access, learning conditions, and academic achievements for girls. The paper also provides an analysis of the adverse effects of community involvement on girls’ education in Senegal. It underscores the extent to which patriarchy and class interfere to shape community involvement and undermine girls’ education, in terms of both access and quality. The paper further sketches a combination …

Progressive Decline Of Testicular Function In Leptinreceptor Deficient Obese Mice, Jennifer Long

Masters Theses

The incidence of obesity and metabolic syndrome among the human population is increasing, but the effects on male fertility are unresolved. Leptin insensitivity appears to show a consistent relationship between obesity and fertility problems in men. Genetically modified mice lacking the leptin hormone (ob/ob) or leptin receptor (db/db) are reported to be subfertile and/or infertile but there is only minimal information about testicular function (sperm and hormone production) and the progression of infertility. Therefore, this study was designed to investigate testicular function using a leptin-receptor-deficient obese mouse model (the POUND mouse; Charles River). Testicular sperm production is reduced in POUND …

The Effects Of Nitrogen Availability And Competition On First Year Perrennial Bunchgrass Growth And Allocation, Jeffrey T. Walker

Masters Theses

Improving seedling survival of perennial bunchgrasses is a key goal of restoration programs in the Intermountain West. Two perennial bunchgrass species commonly used in restoration programs (Agropyron desertorum and Pseudoroegneria spicata) were exposed to two levels of N and competition treatments in a randomized complete block study in a pot study in eastern Oregon. I documented uptake, allocation and resorption of N in plants during the first year of growth. Agropyron desertorum had significantly higher rates of N uptake than P. spicata, but A. desertorum maintained lower tissue N concentrations, suggesting that P. spicata was more likely to …

Children Birth To Age Three With Feeding Difficulties: Systems Level Perspectives Of Supports, Needs, And Interagency Collaboration, Sondra M. Stegenga

Masters Theses

Early identification and treatment of feeding difficulties greatly improves outcomes for young children with feeding difficulties (Williams et al., 2006). However, identifying and addressing feeding difficulties in young children, birth to age three, is complex; requiring not only interdisciplinary collaboration (Arvedson, 2008; Bruns & Thompson, 2010; Lefton-Greif & Arvedson, 2008; Williams et al., 2006) but also interagency collaboration due to the various partners involved in service provision for young children, birth to age three (Individuals with Disabilities Education Act, 2004). When such interagency collaboration is needed, systems level structural supports are shown to levy the greatest impact on outcomes (Tseng …

Female Mate Choice In A Mainland Population Of The Strawberry Poison Frog, Oophaga Pumilio, Meaghan Gade

Masters Theses

Sexual selection and female mate choice are driving forces in the evolution and maintenance of biological diversity, and may function in the evolution of many secondary sexual characteristics throughout multiple taxa. Female mate selection has been experimentally shown to drive the evolution of color between the polytypic populations of the dendrobatid frog, Oophaga pumilio, in the Bocas del Toro archipelago in Panama. However, limited studies exist examining biologically relevant female mate choices within a single population. Using analogous experimental arenas from previous studies, females were presented with two males exhibiting phenotypic extremes from within the same population at La Selva …

Allelopathic Effects Of S. Canadensis On The Germination Of Native Prairie Plants, James David Megenhardt

Masters Theses

Solidago canadensis has become a aggressive species of North American prairie forb throughout the world and within restored prairies throughout North America, causing the loss of biodiversity within those ecosystems. While reproductive methods of wind dispersed seeds and clonal expansion through rhizomes has helped S. canadensis colonize and spread through these ecosystems, S. canadensis also releases allelopathic chemicals which may inhibit the germination and growth of competing species. What was unknown is if these same allelopathic chemicals which give S. canadensis an edge within foreign ecosystems might also explain why S. canadensis is so prolific in restored North American …

Assessing The Impact Of Pre-Meal To-Go Containers On Consumption And Satiety, Claudia Bueno

Masters Theses

Lack of portion control is one of the main causes of obesity. Restaurants offer portions larger than recommended by the USDA. This can lead to portion distortion among consumers and increased consumption. The purpose of this study was to evaluate the effect of offering a to-go box before a meal on reducing consumption.

In this quasi-experimentally designed study, a convenience sample of diners (N=35) served as subjects. The experimental group (n=18) was offered a to-go box before the meal, and the control group (n=17) was offered a to-go box after the meal. The food was …

In Vitro Study Of Wound-Healing Capabilities Of Bioactive Glass Fibers Under Various Culture Conditions, Sisi Chen

Ph Dependent Antibiotic Resistance Of An Alkaliphilic, Halotolerant Bacterium Isolated From Soap Lake, Washington, Tiffany Charlynn Edwards

Masters Theses

"Soap Lake, located in Washington State, is a meromictic, soda lake. Many bacterial isolates retrieved from Soap Lake have been noted to possess resistance to multiple antibiotics. A likely explanation for the wide range of antibacterial resistance exhibited by these strains is due to the impact of high alkalinity on the antibiotics themselves and not due to the presence of antibiotic resistance genes. The aim of our study was to determine if select antibiotics are effective against Halomonas eurialkalitoleranis, a bacterium capable of growth over a wide range of neutral to alkaline pH values, to investigate the influence of alkalinity …

Prior to testing, one familiarization session took place that involved explanation of procedures. This included practice of glute bridging on the vibration plate and the multiple hop performance test. After the familiarization session, two testing sessions …

The Functional Role Of Leaf Nutrients In An Old-Field Successional Community, Kirstin I. Duffin

Masters Theses

In functional ecology, traits that capture aspects of plant performance are used to understand how organisms interact with their environment. Leaf nutrients are an example of a functional trait that directly links to plant metabolic processes and therefore may describe plant assemblage dynamics. Multivariate leaf nutrient analyses may be used with other functional traits to understand ecological strategies because they are a direct measure of leaf metabolic processes and can describe nuances in plant allocation patterns. In this thesis, I explored (1) whether a suite of leaf nutrients (carbon, nitrogen, phosphorus, potassium, calcium, and magnesium) was related to plant growth …

Can Consumers Perceive A Difference In Quality When Comparing Whole-Grain Gluten-Free Baked Goods To Refined Gluten-Free Baked Goods At Varying Flour Levels, Jenna R. Carlson

Masters Theses

The prevalence of celiac disease and gluten intolerances has increased drastically in the last few decades, accounting for 1 in 100 individuals, or about 1% of Americans (Mager, Qiao, & Turner, 2012). The only treatment for celiac disease or any other gluten intolerance is the gluten-free diet. The gluten-free diet can lack many essential nutrients. The purpose of this research was to identify if consumers could perceive a difference in quality when comparing whole-grain gluten-free baked goods to refined gluten-free baked goods at varying flour levels of 20%, 50%, and 100%.

"Race Becomes Biology": Co-Occurring Oral And Systemic Disease As Embodiment Of Structural Violence In An American Skeletal Sample, Rieti G. Gengo

Masters Theses

In recent years, a large number of biomedical studies have demonstrated that the bacteria that contribute to periodontal disease can migrate outside the oral cavity, causing a host of systemic infections. Yet, to date, only one bioarchaeological investigation has addressed this co-occurring disease process in a past population. The results of this thesis confirm the bioarchaeological visibility of the correlation between oral and systemic disease based on data derived from a sample of white and black adults from the Robert J. Terry Anatomical Skeletal Collection. Vertical recessions and porous remodeling of the alveolar crest were examined to identify periodontitis. Periosteal …

Effects Of Fatty Acid Structure On Endothelial Cell Expression Of Connexin43, Albert E. Sowers Iii

Masters Theses

The epidemic of obesity-related metabolic and cardiovascular diseases is linked to elevated fatty acids (FA). Epidemiological data argue that trans FA contribute to the development and progression of these disease processes. Previous work suggests the similarity in structure between saturated and trans FA may stimulate inflammation through trans FA interactions with toll-like receptor 4 (TLR4). To evaluate the impact of trans FA on cardiovascular health, the response of endothelial cells to trans FA was evaluated. Specifically, responses to the 18-carbon trans FA elaidic acid (EA) were compared to the same length cis FA oleic acid (OA). Endothelial cells were exposed …

Characterization Of Histidine Decarboxylase In Drosophila Using An Internal Flag Epitope, Maxwell Mianecki

Masters Theses

Histamine is a neurotransmitter in arthropods and is responsible for synaptic transmission in vision, mechanosensation, temperature sensing and sleep cycle in Drosophila. Histamine is synthesized by the enzyme histidine decarboxylase (HDC). While histamine is detectable within tissues using current immunofluorescent labeling techniques, immunological approaches have not been successful for HDC itself, with both direct antibodies and terminal epitope tags determined to be ineffective. In order to avoid loss of the epitope tag through putative N-­‐ and C-­‐terminal proteolytic cleavage, known to occur for HDC in other organisms, an internal epitope tag that does not disrupt enzyme function was utilized. A …

The Nucleic Acid Binding Properties Of The Pwi Motif, Hamideh Keshavarz-Mohammadian

Masters Theses

The PWI motif is a highly conserved domain that contains a Proline-Tryptophan-Isoleucine (PWI) tripeptide sequence, for which it is named. Proteins that contain a PWI motif are known to be involved in the constitutive and alternative splicing and the 3'-end processing of messenger RNA transcripts. The hypothesized role of the PWI motif is to nonspecifically interact with nucleic acids. The PWI motif is capable of binding both doublestranded and single stranded forms of DNA and RNA. The structure of the highly conserved core of the PWI motif reveals that it adopts a four-helix bundle fold. The structured core domain, however, …

Masters Theses

A preliminary study that utilized the calcified regions of the eyestalks and gastric mills of decapod crustaceans for chronological age determination. The procedure is based on the traditional method for growth analysis of concentric growth bands in otoliths, shells, and genital plates. Transverse cross sections of the eyestalks and prepyloric, pyloric, and zygocardiac ossicles of the gastric mills of Orconectes propinquus and Procambarus clarkii crayfish showed the presence of alternating dark and light growth bands. These growth bands were recorded as a finer secondary series of growth bands found within the broader primary growth bands. Size modal comparisons showed that …

Owning Our Food System: Urban Community Gardening And Local Food Movements, Paige A. Edwards

Masters Theses

Food is a means of examining culture, including identity, autonomy and power. It creates relationships and memories between people via shared connections. Through food, I explore local food movements and urban community gardening.

We both ingest and produce garden-grown foods. This movement is often described as simple nostalgia. I suggest that it is a response against heavily processed foods within a system reliant on mass produced food. This desire for ownership pushes community gardens and other counter-hegemonic spaces forward in their goals of using social practice to challenge the established food industry and take control within their own lives.

The Relationship Between Maternal Child Feeding Practices And Child’S Bmi And Child’S Dietary Restraint In Mexican-American Families Of Grand Rapids, Mi., Larissa E. Fluegel

Masters Theses

Background. Research in Caucasian girls has shown a relationship between mother’s restrictive feeding practices and girls’ eating in absence of hunger and greater body mass index (BMI). Hispanic children disproportionately suffer from obesity, yet there are limited studies on this relationship.

Purpose. This study sought to examine the relationship between maternal feeding practices (MFP) and child BMI (BMI_ch); and to explore the effect of demographics and culture on the latter. The hypothesis that BMI_ch is positively correlated with dietary restriction and monitoring and negatively correlated with pressure to eat was tested.

Subjects. First or second-generation Mexican-American women …

Selling Life To Abortion-Seekers: A Content Analysis Of Passive And Active Persuasion In Crisis Pregnancy Center Marketing, Alexander Kocman

Masters Theses

For supporters of the pro-life cause, crisis pregnancy centers (or CPC's) have become the "darlings of the movement," according to the New York Times (Belluck, 2013), offering women with unplanned pregnancies free advice, information, classes, childcare, and needed supplies. For abortion advocates, such establishments are intended to seduce vulnerable abortion-seekers into a situation where they will be counseled out of an abortion and possibly even proselytized. Yet for as much controversy as exists in the news media, medical community, and legal realm about CPC's, there is an unsettling lack of understanding of how--and why--CPC's market themselves the way they do. …

Energy Tradeoffs Between Food Assimilation, Growth, Metabolism And Maintenance, Lihong Jiao

Masters Theses

"The effect of metabolic rate (MR) on organisms' health maintenance is a long-standing puzzle and empirical data on this issue is contradictory. A theoretical model was developed for understanding animal's energy budget under the food condition of Ad libitum (AL) and food restriction. This model offers a framework for understanding the role of MR and health maintenance mechanism from the perspective of energy tradeoff between food assimilation, growth, metabolism and maintenance. Hornworm (Manduca sexta larva) has been selected as an model to test the energetic tradeoff under different food supply and ambient temperatures. The changes in energy budget can …
