Survival Of The Fictiveness: The Novel’S Anxieties Over Existence, Purpose, And Believability, Jesse Mank

English Theses

The novel is a problematic literary genre, for few agree on precisely how or why it rose to prominence, nor have there ever been any strict structural parameters established. Terry Eagleton calls it an “anti-genre” that “cannibalizes other literary modes and mixes the bits and pieces promiscuously together” (1). And yet, perhaps because of its inability to be completely defined, the novel best represents modern thought and sensibility. The narrative form speaks to our embrace of individualism while its commodification seems so natural, perhaps even democratic, to a capitalist economy. A historical look at the novel’s inception reveals that the …

Aquatic Mesohabitats: Abiotic And Biotic Comparisons In A Sand-Dominated, 3rd Order, Michigan Stream, Edward M. Krynak

Masters Theses

Mesohabitats are visually distinct areas within a stream that provide habitat heterogeneity and increase invertebrate diversity. As such, mesohabitats represent an important spatial scale that underpins the emergent properties, ecology, and ecosystem structure and function of a stream. Within a Western Michigan stream, woody debris, macrophyte beds, and organic matter pools, were examined to determine if visual distinction also relates to a significant difference in abiotic and biotic parameters. Habitats were sampled from July, 2010 – June, 2011 for chemical-physical characteristics including velocity, temperature, pH, conductivity, turbidity and organic matter. Biotic sampling occurred during the same time span and included …

The Neglected Minority: Interviews With Successful Community College Students From Poverty, Heather Hollifield-Hoyle

Graduate Theses and Dissertations

Poverty in the US is growing at an alarming rate. The current economic climate demands higher education to embrace the economic diversity of all students and to prepare them, regardless of economic class, for a globally competitive workplace. Unfortunately, the higher education community is not as adept at serving low-income students, as it is middle- and upper- income students. Low-income students are less likely than their more affluent peers to enroll in college or graduate. Employing qualitative narrative methods, this dissertation explores the factors that contributed to the persistence and success of 18, low-income, community college students. This study addresses …

The Price Of Dissent: Freedom Of Speech And Arkansas Criminal Anarchy Arrests, Jamie Leto Kern

Graduate Theses and Dissertations

Following World War I and the Bolshevik Revolutions, America's Red Scare began, inciting fanatical patriotism and an alleged threat of anarchy that gripped a nation with fear. Paranoia about communists, Socialists, and anarchists divided the country and resulted in many states, including Arkansas, passing criminal anarchy laws. Since a majority of those accused of anti-American activities were involved in labor disputes, Arkansas makes for an interesting case study; not only did it have a relative lack of labor disputes, it still passed anti-Bolshevik laws. The purpose of this research is to develop an understanding of the ways in which dissenters …

Food Environment And Childhood Obesity, Yucong Jiao

Graduate Theses and Dissertations

This thesis examines whether children's food environment, especially food stores that have fresh produce, affects obesity prevalence among elementary school children in the state of Arkansas. Misclassified food outlet types in the Dun and Bradstreet commercial data set were first corrected and then food environment measures were computed and aggregated to geographic regions corresponding to school attendance areas. After applying classical panel estimation, it was found that the fixed effects model fit the data best. Results indicate that an additional supermarket within a one-mile radial of the census neighborhood block center will bring down childhood obesity prevalence by 0.58 percent, …

Effects Of Head Position And Head-Supported Mass On Nerve Function Of The Flexor Carpi Radialis Muscle In Healthy Individuals, Bethany Lauren Shivers

Graduate Theses and Dissertations

Long-term exposure to head-supported mass (HSM) has been linked with spinal degeneration including foraminal stenosis and disc deterioration. Anecdotally, HSM has also been linked to neck and arm pain and muscle atrophy, but nerve function has not been tested specifically. The combined effect of various head positions and HSM may be sufficient to compress the nerve root in aviators and Soldiers during job performance, potentially leading to short- and long-term neuromuscular effects. The Hoffmann (H) reflex, a well-established measure of nerve function, has shown to be sensitive to changes in nerve root space which occurs with different head positions. This …

Optimization Of A Dynamic Hot Water Pretreatment Of Switchgrass Using Catalysis By Carbonation To Maximize Carbochemical Yields, Rohit Tanaji Dhamdere

Graduate Theses and Dissertations

A bio-refinery is a facility that converts renewable bio-resources into value-added chemicals and products. In this context of a bio-refinery, the production of the carbochemicals such as HMF, furfural and organic acids illustrate that multiple products can be produced from a renewable source such as lignocellulosic biomass (switchgrass). Traditionally, carbochemicals such as furfural and HMF are produced using inorganic acids such as H2SO4, HCL, and H3PO4. The use of such acids requires the application of high cost materials of construction such as Hastelloy-C, titanium etc.

The objective of this study is to develop a semi-continuous process for the conversion of …

Optimization Models And Algorithms For Truckload Relay Network Design, Hector Andres Vergara Arteaga

Graduate Theses and Dissertations

Driver turnover is a significant problem for full truckload (TL) carriers that operate using point-to-point (PtP) dispatching. The low quality of life of drivers due to the long periods of time they spend away from home is usually identified as one of the main reasons for the high turnover. In contrast, driver turnover is not as significant for less-than-truckload (LTL) carriers that use hub-and-spoke transportation networks which allow drivers to return home more frequently. Based on the differences between TL and LTL, the use of a relay network (RN) has been proposed as an alternative dispatching method for TL transportation …

Cell Bioenergetics In Leghorn Male Hepatoma Cells And Immortalized Chicken Liver Cells In Response To 4-Hydroxynonenal Induced Oxidative Stress, Alissa Laura Piekarski

Graduate Theses and Dissertations

Bioenergetic mechanisms responsible for ATP production are essential in carrying out maintenance and cell-specific functions. In this study, hepatocytes (liver cells) were used to test both endogenous and exogenous stress on cellular respiration. The secondary lipid peroxide, 4-hydroxynonenal (HNE), was used because it alters bioenergetics by increasing mitochondrial proton leak that attenuates mitochondrial radical production and, therefore, endogenous oxidative stress. The major objective of this study was to demonstrate effects of HNE-induced oxidative stress on avian hepatocyte bioenergetics. Various chemical which help enable the determination of oxygen (O2) consumption linked to ATP synthesis (oligomycin), maximal O2 consumption (FCCP), and proton …

The Identification Of Quantitative Trait Loci For Sucrose And Stachyose Content In Soybean Seed, Ailan Zeng

Graduate Theses and Dissertations

Sucrose is a desirable sugar in soybean seed that affects the quality and taste of soyfoods, while stachyose is a non-digestible sugar that induces flatulence in non-ruminant animals. Therefore, soybean cultivars with high sucrose and/or low stachyose would be valuable for soyfood and meal markets. The objectives of this study were to identify quantitative trait loci (QTL) or genes associated with seed sucrose and stachyose content using simple sequence repeat (SSR) or single nucleotide polymorphism (SNP) markers. A low sucrose line, MFS-553, was crossed with a high sucrose plant introduction, PI 243545, to develop the sucrose QTL mapping population. A …

Consumer Sensory Preferences And Willingness-To-Pay For Nutraceutical-Rich Fruit, Lydia Lawless

Graduate Theses and Dissertations

Health-oriented juices are prime candidates for the nutraceutical market due to their inherent healthfulness and convenience. Fruits such as açaí berries, blueberries, blackberries, black cherries, Concord grapes, cranberries, and pomegranates are rich in potentially health-supporting polyphenolics, which makes the juices of these fruits attractive for nutraceutical optimization. The compositional, sensory, and stability properties of blueberry, blackberry, and Concord grape juice blends were explored in an extended shelf-life study. Initially, 100% blueberry juice had the highest total monomeric anthocyanins (67.40 mg/100mL), 100% blackberry juice had the highest total phenolics (249.24 mg/100mL), and 100% Concord juice had the highest polymeric color (23.21%). …

A Reexamination Of The Eastern Collared Lizard (Crotaphytus Collaris Collaris) In Arkansas, Ashley A. Grimsley

Graduate Theses and Dissertations

Loss of suitable habitat is a threat to species worldwide. Habitat destruction, including loss, change, and fragmentation of habitat, is the leading cause of species extinction. Eastern collared lizards (Crotaphytus collaris collaris) are habitat specialists on glades. Both C. c. collaris and glade habitats are rare and of special concern in the state of Arkansas. Many glade populations have already been extirpated in the Ozarks of Arkansas and Missouri. Increasing knowledge of the distribution, habitat structure, and population dynamics of C. c. collaris is important to ensure the survival of this species in Arkansas.
