Successful Weight Loss, Weight Loss Maintenance And Psychological Characteristics In Minority Men And Women Attending An Inner-City Weight Loss Program, Julie Ann Hall

Masters Theses

Inner-city communities are disproportionately impacted by obesity and chronic disease. The LOSE BIG Challenge is a motivational physical activity and nutrition education program offered to inner-city Grand Rapids, Michigan residents with diabetes or hypertension. Twenty-eight participants (26 women, 2 men) in a 12-week culturallybased weight loss program were studied. Before and after the intervention, height, weight, lifestyle information, readiness to change, eating behaviors, depression scores, and quality of life scores were measured. Participants were followed 4 and 6 months post intervention. At baseline, 86% of the participants were obese (BMI >30 kg/m²), 54% watched more than ten hours …

The Church Of Craiglockhart: Wilfred Owen And Siegfried Sassoon‘S Critique And Use Of Religion In Their World War I Poetry, Brian Karsten

Masters Theses

Throughout history, faith and religious principles have been used as motivation for war. Accordingly, political leaders, religious leaders, and writers all used religion-themed propaganda to encourage enlistment in World War I. Two soldier poets, Siegfried Sassoon and Wilfred Owen, after meeting in the asylum of Craiglockhart, together recognized the injustice represented in using faith to promote warfare. Subsequently, they wrote poetry which criticized the religious and political hierarchy, countered the theology used in propaganda, and attempted to reveal the atrocities in battle. Although Sassoon‘s poetry remained satirical of the use of religion, Owen recognized its power and used religion and …

Masters Theses

The research presented here is summary two years of studying the Biosand filter (BSF) both in Haiti during March 2011 and in the laboratory. In Chapter 2, we examined the long term use and sustainability 55 BSF systems near Deschapelles, Haiti and 47% were found to be no longer in use. Interviews with BSF owners revealed problems related to intermittent filter use. A review of 17 BSF field studies also was included to compare and substantiate observations made in Haiti. Together, previous field studies and our observations point toward the importance of providing culturally appropriate technologies and education materials explaining …

The Role Of Saturated Fatty Acids In Connexin Expression On Endothelial Cells And Eosinophils, Kurt Anthony Ashack

Masters Theses

Eotaxin is a potent chemoattractant for eosinophils that becomes elevated in the tissues in response to inflammation and increased adiposity. Therefore, eosinophil migration into adipose tissue should increase in diet-induced obese individuals, yet it does not. This suggested to us that something within the cellular microenvironment of diet-induced obese individuals might be altering the endothelial leukocyte adhesion molecules (ELAM) such as VCAM-1 or selectins on the endothelial cells, thus preventing eosinophils from entering the inflamed tissue. Connexons are gap junctions in endothelial cells and on immune cells such as macrophages that are composed of connexins and have been shown to …

Tropisetron As A Neuroprotective Agent Against Glutamate-Induced Excitotoxicity: Potential Mechanisms Of Neuroprotection, Michael M. Swartz

Masters Theses

Glutamate-induced excitotoxicity has been shown to play a key role in a number of neurodegenerative diseases of the central nervous system. Activation of nicotinic acetylcholine receptors (nAChRs) significantly protects various types of neuronal tissues from excitotoxic cell death (Kaneko et al., 1997; Dajas-Bailador et al., 2000; Wehrwein et al., 2004; Thompson et al., 2006). Tropisetron is a highly selective 5-HT3 class serotonin receptor antagonist that is also a partial acetylcholine (ACh) agonist of the α7 nAChR (Papke et al., 2005). In the current study we aim to determine if tropisetron offers protection to adult pig RGCs. We further aim to …

Laboratory Measures Of Aggression In Methadone Patients, Catherine M. Gayman

Masters Theses

Research suggests that current heroin users and individuals with a prior history of heroin dependence tend to be more aggressive than nonusers. No study has yet investigated whether opioid withdrawal affects aggressive responses on a laboratory task. The present study investigates whether mild opioid withdrawal affects aggression in six males and six females (N=12) undergoing methadone maintenance therapy. Aggressive behavior is measured using the Point Subtraction Aggression Paradigm (Cherek, 1981) computer task. Participants press buttons to earn money towards gift certificates. Money subtractions occur periodically and these are attributed to the behavior of a partner who is actually fictitious. Participants …

Assessing The Impacts Of Dams On Nutrient And Sediment Loading In The Kalamazoo River Using The Soil And Water Assessment Tool (Swat), Daniel Henry Serfas

Masters Theses

The Soil and Water Assessment Tool (SWAT) was applied to the Kalamazoo River Watershed in order to evaluate the impacts that several dams within a superfund site "Area of Concern" have on the sediment, nutrients, and streamflow of the system. It was hypothesized that the SWAT model could be used to recreate the watershed in hopes of estimating the amounts of nitrogen, phosphorus, and sediment that would result from the removal of the dams. The model would then be used to evaluate dam removal scenarios to come up with a best management practice (BMP).

The model was calibrated, however, during …

Lignin Yield Maximization Of Lignocellulosic Biomass By Taguchi Robust Product Design Using Organosolv Fractionation, Anton Friedrich Astner

Masters Theses

Lignin, a byproduct of the organosolv pretreatment process using lignocellulosic biomass from switchgrass (Panicum virgatum) and tulip poplar (Liriodendron tulipifera) is currently being explored for its potential use in the production of value-added chemicals and biobased polymers. Pretreatment is one of the most expensive processing steps in cellulosic biomass conversion. Optimization of the process is one of the major goals of the biomass-toethanol conversion process. Taguchi Robust Product Design (TRPD) provides an effective engineering experimental design method for optimizing a system and designing products that are robust to process variations. Given the results of several preliminary …

The Effect Of Common Imaging And Maceration Techniques On Dna Recovery From Skeletal Remains, Emilie Margaret Frank

Masters Theses

DNA testing is an essential tool for human identification, particularly from skeletal remains. Therefore it is important to understand how different processing methods used to clean and prepare bones for research and analysis influence the recoverability of CODIS marker DNA from skeletal remains. Thirteen elements from three sets of recently skeletonized remains were macerated with hot water, scanned by computed tomography (CT), X-rayed, or exposed to a combination of the three methods. The number of CODIS marker loci, relative fluorescent units (RFU) values and DNA yields were compared to an unprocessed control group to determine if there was a significant …

Beat-Class Tonic Modulation As A Formal Device In Steve Reich's "The Desert Music", Liahna Rochelle Guy

Masters Theses

Beat-class analysis is a model of rhythm employed by Richard Cohn and John Roeder to analyze textural form in the compositions of Steve Reich (Roeder 2003, 275). Rhythmic attacks are regarded based on the modulus analytically assigned to a particular section (eighth note, sixteenth note, etc.). This paper will offer an in-depth analysis of beat-class modulation and transposition in Steve Reich’s The Desert Music, with a focus on the third movement. Applying this analytical technique to The Desert Music (a piece never before analyzed using beat-class analysis) proposes a fresh analytical approach to Reich’s 1984 piece. This perspective will …

On The Spherical Symmetry Of Perfect-Fluid Stellar Models In General Relativity, Joshua M Brewer

Masters Theses

It is well known in Newtonian theory that static self-gravitating perfect fluids in a vacuum are necessarily spherically symmetric. The necessity of spherical symmetry of perfect-fluid static spacetimes with constant density in general relativity is shown.

(Re)Conceptualizing Death: Examining Attitudes Toward Death At The Anthropological Research Facility, Kiley Nicole Compton

Masters Theses

The Anthropological Research Facility (ARF), commonly known as the “Body Farm,” provides a unique research setting in which researchers work intimately with human remains in various stages of decomposition. While the ARF, and forensic anthropology, is well documented in popular culture, little academic research has been conducted to investigate the sociocultural phenomena associated with working with human remains.

This thesis investigates the reactions and attitudes toward death of those involved in operational and administrative duties at the ARF focusing on how these attitudes influence and are influenced by involvement at the facility. This research also provides a point of departure …

Impact Of Rearing Conditions On The Microbiological Quality Of Retail Poultry Meat, Bridgshe Hardy

Masters Theses

Poultry and poultry products are a leading source of foodborne pathogens and illnesses. The rearing conditions of poultry can be an influential factor on the presence of foodborne pathogens including Campylobacter and Salmonella because some types of rearing practices have increased risks in terms of biosecurity. However, there is a gap in knowledge of food safety in raw chicken products and no studies have reported the microbiological quality of turkeys produced under different rearing environments. Thus, the aim of this study was to compare conventionally and organically-reared whole chicken and turkey carcasses purchased from three retail outlets in Knoxville, TN. …

Fatigue Behavior Of High-Entropy Alloys, Michael Alexander Hemphill

Masters Theses

Research was performed on the Al₉Co_18.2Cr_18.2Cu_18.2Fe_18.2Ni_18.2 [subscripts atomic percent] and Al_7.5Cr_22.5Fe₃₅Mn₂₀Ni₁₅ high-entropy alloys (HEAs) in an attempt to study their fatigue behavior. The present investigation shows encouraging fatigue-resistance characteristics due to their high fatigue lives of various samples at relatively high stresses. The current results indicate that the fatigue behavior of HEAs compares favorably to many conventional alloys, such as steels, titanium alloys, and advanced bulk metallic glasses with a fatigue-endurance limit of the Al₉Co_18.2Cr_{18.2 …}

Testing A Novel Technique To Improve Aluminum-26 Accelerator Mass Spectrometry Measurements For Earth Science Applications, Meghan Sarah Janzen

Masters Theses

The measurement of cosmogenic ²⁶Al [aluminum-26] in geological samples by accelerator mass spectrometry (AMS) is typically conducted on Al₂O₃ [aluminum oxide] targets. However, Al₂O₃ is not an ideal source material because it does not form a prolific beam of Al^- [negative atomic aluminum ions] required for measuring low-levels of ²⁶Al. This thesis presents the performance of AlN [aluminum nitride], AlF₃ [aluminum fluoride] and mixed AlN + Al₂O₃ as novel alternative source materials for the analysis of ²⁶Al. A negative ion cesium sputtering source at the Holifield …

Adipose Tissue's Potential Role As A Reproductive Or Lactation Endocrine Gland, Megan Gray Macdougal

Masters Theses

While adipose tissue secretes hormones related to nutrition and metabolism, a few studies have provided evidence suggesting a direct reproductive role from adipose-derived products. The goal of this study was to determine if adipose tissue serves as a reproductive or lactation endocrine gland. Adipose tissue was associated with the reproductive tract of mature female cows in two locations, mesosalpinx and mesometrium (tissues supporting the oviduct and uterus, respectively), in varying amounts. Using quantitative polymerase chain reaction on a non-descript pool of cows, LHβ, CGA, PRL, FST, and LEP transcripts were demonstrated to be present in mesosalpinx, subcutaneous, visceral, and peri-renal …

Online Social Network Friends And Spatio-Temporal Proximity Of Their Geotagged Photos – A Case Study Of Flickr Data, Sumang Liu

Masters Theses

This empirical study aims to analyze relationships between online social network (OSN) friends and spatio-temporal proximity of their geotagged photos, using Flickr data as a case study. First, this study analyzes whether Flickr friends tend to post geotagged photos that are closer to each other compared to Flickr non-friends in space and time. Second, this study investigates whether the number of geotagged photos posted by users is related to the distance and time difference between their geotagged photos. Third, this study examines the spatial distributions of geotagged photos of Flickr friends within specific distance intervals to further understand the geographic …

Consider The Source: Receiver-Assigned Attributions Of Credibility To Influential Bloggers, Aaron Michael Sachs

Masters Theses

The purpose of this study is to examine credibility as it pertains to blogging. While studies have traditionally considered credibility in the context of the material being created, this study examines source credibility in the context of the personality creating the material. Therefore, this study functions primarily as an exploratory study and seeks to present an understanding of source credibility from the perspective of the individuals participating in blogging communities cultivated by influential bloggers. An interview questionnaire was specially developed for this study. Ten participants were selected for this study. Eight of them are females, two of the participants are …

Implicitly And Explicitly Assessed Relationship Satisfaction, Matthew Jason Shaffer

Masters Theses

This study investigates the relationship between implicitly assessed (i.e., unexpressed, sometimes unconscious, “gut-level”) attitudes and explicitly assessed attitudes in romantic couples. 135 newlywed couples were examined in a laboratory session. A series of Hierarchical Linear Models were run to assess whether implicitly assessed attitudes predict the use of demand-withdraw behaviors in conflict discussion tasks. Results indicate that, for demand behaviors, there is a 3-way interaction between implicitly assessed attitudes, participant sex, and partner behavior during the discussion task. Implicitly assessed attitudes did not predict withdraw behaviors. Theoretical implications for both implicitly assessed attitudes research and romantic relationships research are discussed.

On Decision Making: Bayesian And Stochastic Optimization Approaches, Yang Shen

Masters Theses

Decision analysis provides a framework for searching an optimal solution under uncertainties and potential risks. This thesis focuses on two problems arising in transportation engineering and computer sciences, respectively.

First, it is considered a centralized controller which imposes actions on a number of interacting subsystems. Employing an appropriate Markov Decision Process framework, we establish that the Pareto optimal solution of each subsystem will be optimal for the entire system. Synthetic data have been taken into account for verifying this claim.

Next, we focus on a supercomputing problem utilizing a hierarchical Bayesian model. We estimate an optimal solution in order to …

The Accidental College Student, Phyliss Dubinsky Shey

Masters Theses

This narrative study began as a retrospective of an in-depth interview study with a young woman who navigated the move from a large, suburban school system in the mid-Atlantic region before the fifth grade to a small, isolated rural school in Southern Appalachia in the 1990s. She graduated from the only high school serving the county in which she lived. Over the course of two formal interviews, hundreds of informal conversations for more than ten years, and particularly through writing this analysis (Goodall, 2000), I realized that even though there were vast differences between our ages, cultural backgrounds, and current …

Rejection Sensitivity In Adolescent Offspring Of Mothers With Borderline Personality Disorder, Jennifer Marie Strimpfel

Masters Theses

Borderline Personality Disorder (BPD) is a chronic and severe psychological disorder with symptoms including fear of abandonment, negative relationships, and inappropriate expressions of anger. Individuals with BPD score higher on rejection sensitivity than do normative comparisons. The present study assessed rejection sensitivity in a sample at high risk for developing BPD—adolescent offspring of women with BPD. We hypothesized that adolescents whose mothers have BPD would have higher levels of rejection sensitivity than would normative comparisons, adolescents’ rejection sensitivity would be positively correlated with their mother’s borderline features, and adolescents’ rejection sensitivity would be positively correlated with their own borderline features. …

Motivated Endorsement Of Interethnic Ideologies: An Optimal Distinctiveness Approach, Kevin Lee Zabel

Masters Theses

The current study examined the effects of need for inclusion and differentiation (Brewer, 1991) activations on endorsement of colorblind and multicultural ideologies, and the roles ideological endorsements played in visual social perception. A total of 238 university students were given false feedback on a personality inventory to activate needs for differentiation and inclusion, as well as completed interethnic ideology measures and a morphed faces judgment task in which they perceived whether paired others were exactly the same or different. Bootstrapping analyses (Preacher & Hayes, 2008) confirmed that, consistent with hypotheses, need for inclusion activation participants endorsed colorblind ideology to a …

Power Management For Cloud-Scale Data Centers, Yanwei Zhang

Masters Theses

Recent years have seen the rapid growth of large and geographically distributed data centers deployed by Internet service operators to support various services such as cloud computing. Consequently, high electricity bills, as well as negative environmental implications (e.g., CO2 emission and global warming) come along. In this thesis, we first propose a novel electricity bill capping algorithm that not only minimizes the electricity cost, but also enforces a cost budget on the monthly bill for cloud-scale data centers that impact the power markets. Our solution first explicitly models the impacts of the power demands induced by cloud-scale data centers on …

Die Rolle Des Opfers In Der Fiktionalen Darstellung Der „Landshut“- Entfuehrung In Literatur & Film, Annica Esther Eisenhofer

Masters Theses

In this thesis I examine the cinematic and literary portrayal of victims during the hijacking of the Lufthansa plane, Landshut by Palestinian terrorists in October 1977. I discuss the book, Mogadischu Fensterplatz by the German author Friedrich Christian Delius and two films, the docudrama Todesspiel by the director Heinrich Breloer, and the film Mogadischu by the director Roland Suso Richter.

The study compares and contrasts alternate means of portraying the plight of the hijacking victims through different forms of media. Mogadischu Fensterplatz is a book whose text comprises a single victim’s personal narrative. The backbone of Todesspiel is a chronology …

"Sing To The Lord A New Song": Memory, Music, Epistemology, And The Emergence Of Gregorian Chant As Corporate Knowledge, Jordan Timothy Ray Baker

Masters Theses

Following the Christianization of the crumbling Roman Empire, a wide array of disparate Christian traditions arose. A confusion of liturgical rites and musical styles expressed the diversity of this nascent Christendom; however, it also exemplified a sometimes threatening disunity. Into this frame, the Carolingian Empire made a decisive choice. Charlemagne, with a desire to consolidate power, forged stronger bonds withRome by transporting the liturgy ofRome to the Frankish North. The outcome of this transmission was the birth of a composite form of music exhibiting the liturgical properties ofRome but also shaped by the musical sensibilities of the Franks—Gregorian chant.

This …
