Examining The Effect Of Climate Change On The Upper Mesophotic Coral Montastrea Cavernosa (Linnaeus 1767), John Skutnik

Masters Theses

Coral reefs are under increasing pressure from global climate change. In particular, ocean warming is having a deleterious effect on many of the world’s shallow reefs. Some authors suggest that acute exposure is more detrimental than chronic, versus others who indicate the opposite. However, little knowledge exists regarding heat induced stress on deeper mesophotic reefs. Here, I examined the effect of acute (72 hrs.) and chronic (480 hrs.) heat stress using laboratory experiments on coral Montastraea cavernosa (Linnaeus 1767) collected from an upper mesophotic (~30 m) reef off Islamorada Florida. I examined a variety of putative immune and stress genes …

The Effect Of Seasonal Fish Migration On Energy Budgets In Two Coastal Michigan Streams, Emily M. Dean

Masters Theses

Migratory fish are known to seasonally enter coastal stream systems but the magnitude of the effects these migrations have on stream energy budgets is not fully understood. The Laurentian Great Lakes have several introduced and native adfluvial fish, where only a few studies have investigated the impacts of their migration on energy budgets in Michigan coastal streams. We quantified the contribution of energy from Chinook salmon (Oncorhynchus tshawytscha) muscle and eggs, steelhead (Oncorhynchus mykiss) eggs, and larval white suckers (Catostomus commersonii) to coastal stream energy budgets. Energy densities and energy delivered to streams were estimated using bomb calorimetry and annual …

Assessment Of A New Healthy Food Policy At Two Food Pantries In Grand Rapids, Mi, Katherine D. Hekstra

Masters Theses

Background The purpose of food pantries has traditionally been to provide short-term assistance to food insecure individuals, however recent research indicates that food pantries are often used longer periods of time. This increased use indicates a greater importance for food pantries to distribute nutrient-dense foods to food insecure individuals, some who may suffer from chronic disease. Objectives This study measured food pantry client satisfaction pre- and post- implementation of a new healthy food policy at two Grand Rapids, MI food pantries. An additional purpose was to measure the change in food environment and distribution of nutrient-dense foods after implementation of …

Relationally Managing Weight Loss, Clinton L. Brown

Masters Theses

Previous research emphasizes the link between social support and weight loss. However, scholarship has failed to explore how family members enact support during an individual's weight loss attempt and how participation in a weight loss program impacts family communication about dietary choices. This project examines how family members enact support for individuals in a weight loss program and how as a result of participating in a weight loss program family members renegotiate relational norms and rules regarding dietary behaviors. Thirteen individuals (n= 13), eleven (11) females and two (2) males enrolled in a medically supervised weight management program journaled about …

White-Rot Fungi As Pretreatment Agents For Wood Destined For Biofuel Applications, Ryan M. Kalinoski

Masters Theses

Efficient and economical conversion of lignocellulosic biomass to biofuels is often hampered by the chemical recalcitrance of the material. Inexpensive and environmentally-friendly pretreatment processes are therefore desirable in order to lower the cost of biofuel production and minimize negative environmental impacts. To that end, we have explored the use of a naturally occurring white-rot fungus, Trametes versicolor, as a direct pretreatment agent for hardwood destined for biofuel applications. Specifically, we examined the pretreatment effects on the hardwood mixture after treatment with the wild-type strain of T. versicolor (52J) compared with those from a cellobiose dehydrogenase (CDH)-deficient strain (m4D) , …

Is The Demand For Health Care Income Elastic? The Case Of 40 Sub-Saharan African Countries, Meron Masresha Nadew

Masters Theses

This paper uses panel data (1995 to 2011) from 40 Sub-Sahara African countries to analyze the income elasticity of health care expenditure along with some of the other theoretical determinants. The empirical results of the instrumental variable approach indicate that per capita income is a core and statistically significant determining factor of health expenditure. The value of the elasticity is about 0.48, suggesting that health expenditure as a commodity is a necessity for this region. In simple words, the goal of the system in this region is curative rather than caring. The percentage of population age 65 or older and …

Behavioral Patterns Of The Cannibalism And Sexual Taboos, Kayla R. Rice

Masters Theses

Previous research has suggested that there may be a connection between the cannibalism taboo and sexual attraction. Specifically, it appears that when forced to choose someone to cannibalize, people choose victims in a pattern that mimics who they would choose to be sexually intimate with. To confirm and explore this relationship, the current study measured sexual orientation and examined whether participants' preferences in who to cannibalize if forced reflected their desired sexual partner. Participants recruited from Amazon Turk responded to forced pair choices regarding either desired sexual partner or cannibalism victims. Targets included all combinations of three variables: Physical Appearance …

Correlation Between Sleep And Lifespan In Drosophila Melanogaster, Courtney H. Fiebelman

Masters Theses

”Sleep has previously been associated with lifespan. Monitoring sleep in any given fly over their lifetime facilitates the ability to predict the lifespan of that given fly. Using this estimate, lifespan can potentially correlate with biological age to identify when health parameters have declined.

To confirm that the prediction algorithm could identify short and long-lived flies, glutathione levels in heads and bodies were compared between two groups. The results showed this to be consistent in the bodies of wild-type Canton S male flies, and showed that glutathione was decreased in the predicted biologically older flies. These data show that glutathione …

Using Adaptive Thresholding And Skewness Correction To Detect Gray Areas In Melanoma In Situ Images, Jason R. Hagerty

Masters Theses

"The incidence of melanoma in situ (MIS) is growing significantly. Detection at the MIS stage provides the highest cure rate for melanoma, but reliable detection of MIS with dermoscopy alone is not yet possible. Adjunct dermoscopic instrumentation using digital image analysis may allow more accurate detection of MIS. Gray areas are a critical component of MIS diagnosis, but automatic detection of these areas remains difficult because similar gray areas are also found in benign lesions. This paper proposes a novel adaptive thresholding technique for automatically detecting gray areas specific to MIS. The proposed model uses only MIS dermoscopic images to …

Seeing Red In A Sea Of Green: Anthocyanin Production In A Carnivorous Plant, Pinguicula Planifolia, Jenna Annis

Masters Theses

The Southeastern United States is a biological hot-spot for carnivorous plants, with over half of the North American species occurring along the Gulf Coast. Pinguicula planifolia Chapman is one of six carnivorous perennial butterwort species found in the Florida Panhandle. Among these species, only P. planifolia expresses a distinct variation of red coloration on its leaves. The functional role of foliar anthocyanins may include stress response to drought and nutrient deficiency, herbivory defense, free radical scavenging, and photoprotection. Carnivorous plant leaves face strong selection pressures to optimize prey capture and nutrient absorption. Given the frequency of these red pigments in …

Successional Changes In Leaf Nutrient Concentrations Of Woody And Herbaceous Species, Daniel Walter Kuchta

Masters Theses

Leaf nutrient concentrations are an example of a functional trait, a trait that can be used to understand community dynamics by observing how plants interact with their environment. I explored how leaf nutrient concentrations were affected over successional time by environmental changes. The majority of prior research on functional traits focuses on either woody or herbaceous species, but not both life forms simultaneously. To address this, I also explored the successional changes to leaf nutrient concentrations, separating the plant community into woody and herbaceous species.

Healthy, mature leaves were taken from 122 taxa of woody and herbaceous species in a …

Expression Of Insulin Responsive Genes In Insulin Resistant Conditions, And The Effect Of Selenium On Gene Expression, David L. Ruff

Masters Theses

Chronically high blood glucose levels lead to many problems, such as insulin resistance, the hallmark of Type II diabetes. Increased flux through the hexosamine biosynthesis pathway is one mechanism by which high glucose as well as glucosamine has been shown to induce insulin resistance. This study tests the effects of glucosamine induced insulin resistance on insulin regulation of the metabolic genes glucose-6-phosphate dehydrogenase (G6PDH) and fatty acid synthase (FAS) as well as insulin responsive proteins tribbles homolog (TRIB3) and sterol regulatory element binding protein (SERBP-1c) 1c.

Selenium, a micronutrient has been shown to be an effective insulin mimetic in Type …

Cultural Influence Of Storytelling: An Examination Of The Use Of Narratives In Political Campaigns, Charla Bansley

Masters Theses

Television has changed political discourse. The thirty second commercial has replaced typography and rhetoric. After losing the popular vote in 5 of the last 6 presidential elections, the Republican National Committee concluded that the GOP has lost the ability to persuade. Walter Fisher's Narrative Paradigm states that meaningful communication is in the form of storytelling, which enables public discourse to observe not only differences, but commonalities. In a postmodern culture that does not believe in absolute truth, this study asked the following question: Are conservatives still using statistics and facts to communicate conservative principles? The rhetorical research conducted here examined …

The Spirit Molecule: Dmt, Brains, And A Theoneurological Model To Explain Spiritual Experiences, Shaun Smith

Masters Theses

This thesis attempts to address the philosophical implications of the N, N-Dimethyltryptamine (DMT) research of Dr. Rick Strassman. Strassman concludes that the psychedelic properties of DMT represent a proper biological starting point for discussing spiritual and near-death experiences. My research attempts to incorporate philosophical elements from the philosophy of mind and philosophy of religion/mysticism to give an accurate account of some of the philosophical issues worth exploring for future research. One of the essential patterns in this thesis is to trace the research and conclusions of Strassman, compare them with the philosophical issues in the contemporary philosophy of mind and …

Breastfeeding With The Bronson Mothers’ Milk Bank, Marykate Bodnar

Masters Theses

Bronson Methodist Hospital in Kalamazoo is home to one of only 15 certified breast milk banks in the United States. Women have shared breast milk for centuries through wet nurses, but this institutionalized and regulated version of sharing is distinct from previous forms. Breastfeeding has become a symbol of successful motherhood; donor milk adds a new dimension to this aspect of idealized motherhood. This study explores how the milk bank works: its organizational structure within a hospital, how donors are selected, and how recipients qualify for donor milk. It is grounded in Feminist and Medical Anthropology literature. Using semi-structured interviews …

These sites, investigated by the Finger Lakes National Forest Farmstead Archaeology Project, produced a rich sample of over 250,000 artifacts and thousands related to canning.

The objective of this thesis is to explore the potential of these common artifacts to yield important information about these Backbone households. Specifically, my questions include: when did these households adopt canning and who were they?

The intentional decision to include …

Sleep Hygiene Practices: A Cross Cultural Survey Of Sleeping And Dreaming In College Students, Ivan Noe Martinez Salazar

Masters Theses

There is consensus that a sizeable percentage of people in most developed countries do not obtain adequate amounts or quality of sleep. These disruptions in sleep, when chronic and severe, can lead to psychological, behavioral and health consequences. The focus on behavioral and contextual factors that impact sleep has been termed “sleep hygiene”. An on-line anonymous survey collected sociodemographic information, as well as self-reports on sleep, sleep hygiene practices and dreaming across two cultural groups (English & Spanish speaking responders). A total of 204 participants (majority of them college and graduate students) answered the survey. Both cultural groups, English and …
