Determinants Of Bite Force In Four Species Of Sharks From The Gulf Of Mexico With An Emphasis On The Atlantic Sharpnose Shark, Rhizoprionodon Terraenovae, Kyle Walter Rice Jan 2014

Determinants Of Bite Force In Four Species Of Sharks From The Gulf Of Mexico With An Emphasis On The Atlantic Sharpnose Shark, Rhizoprionodon Terraenovae, Kyle Walter Rice

Electronic Theses and Dissertations

Bite force can provide valuable information regarding the physiological ecology of an organism. However, there have been few studies wherein bite force in sharks has been considered. Herein I report on a study of the bite force of four species of sharks with particular emphasis on that of the atlantic sharpnose shark, rhizoprionodon terraenovae. Among the four species examined, blacktip shark, carcharhinus limbatus bite force was significantly higher than that of sharpnose, rhizoprionodon terraenovae. There was no significant difference between the bite force of those species compared with the same for finetooth shark, c. Isodon and spinner shark, c. Brevipinna. …

Transformation Of Early Nineteenth Century Chickasaw Leadership Patterns, 1800-1845, Emily Paige Smithey Jan 2014

Transformation Of Early Nineteenth Century Chickasaw Leadership Patterns, 1800-1845, Emily Paige Smithey

Electronic Theses and Dissertations

This is an examination of the changing leadership patterns of the Chickasaw Nation during the early nineteenth century, and combines the internal function of Chickasaw government with the leaders' responses to overwhelming external factors. This thesis begins in 1800, a time that hinges on the remnant Chickasaw political leadership offices of previous centuries, such as the Minko and Tisho Minko, combined with the formation of newer offices such as district chiefs. It ends in 1845 after the Chickasaws were forced to remove from their Mississippi homelands into the Indian Territory. After removal, the Chickasaws began a more centralized form of …

Pretreatment Of Cellulosic Biomass By Iron-Containing Magnetic Ionic Liquid Dissolution, Christopher Roth Riley Jan 2014

Pretreatment Of Cellulosic Biomass By Iron-Containing Magnetic Ionic Liquid Dissolution, Christopher Roth Riley

Electronic Theses and Dissertations

The focus of this project is to determine the effectiveness in the preprocessing of biomass when magnetic ionic liquids (MIL) (1-butyl-3-methylimidazolium tetrachloroferrate (Bmim[FeCl4]) and 1-ethyl-3-methylimidazolium tetrachloroferrate (Emim[FeCl4])) are used as a green solvent. Lignocellulose is a promising starting material for a plethora of products, ranging from biofuels to custom chemicals; however, lignocellulose is resistant to enzymatic degradation. Various biomass-preprocessing techniques such as microbial, mechanical, and chemical pretreatment are used for enhancing the digestibility of biomass to sugars for ethanol production. Varieties of ionic liquids have demonstrated the ability to fragment lignocellulose. However, after fragmentation, separation of biomass and ionic liquids …

Transgenerational Transmission Of Trauma In Second Generation Latino Children And Adolescents, Ricardo Phipps Jan 2014

Transgenerational Transmission Of Trauma In Second Generation Latino Children And Adolescents, Ricardo Phipps

Electronic Theses and Dissertations

This study explored the impact that immigration-related trauma has upon families, particularly second-generation immigrant children in the Latino-American community in the United States, and the possibility that second-generation immigrant Latinos are vulnerable to transgenerational trauma. Transgenerational trauma involves the exhibition of posttraumatic stress disorder (PTSD) symptoms in subsequent generations in families with histories of trauma exposure. Multiple linear regression was conducted to explore the existence of a correlation between PTSD and depression in second-generation Latino immigrant children and adolescents with a myriad of potentially predicting factors. Enhanced understanding of how trauma can affect the children of traumatized immigrants will add …

The Beowulf Poet's Accommodation Of Pre-Christian Germanic Culture, Walter Beverly Jan 2014

The Beowulf Poet's Accommodation Of Pre-Christian Germanic Culture, Walter Beverly

Electronic Theses and Dissertations

This thesis argues for the Beowulf poet's more accommodating perspective on pre-Christian Germanic culture, when examined in comparison to other, later Germanic authors of works such as Icelandic sagas and Danish pseudo-history. The primary components of Beowulf I address to argue for this point are the poet's incorporation of pagan Germanic cosmology, and his rendering of Beowulf according to two different heroic types in Germanic literature, those being the model thane and the model king.

Uneven Ground: Figurations Of The Rural Modern In The U.S. South, 1890-1945, Benjamin S. Child Jan 2014

Uneven Ground: Figurations Of The Rural Modern In The U.S. South, 1890-1945, Benjamin S. Child

Electronic Theses and Dissertations

New modernist studies has opened wide the discussion about what modernism means, when it begins, and, compellingly for the purposes of this project, where it occurs. Exploring intersections between modernization, modernism, labor, and segregation in the agricultural South, this dissertation demonstrates how the effects of nascent industrialization, emergent technologies, and "modern" thought are animated by figures and spaces associated with--or performing--versions of rurality. The project is divided into three major sections. In the first, I suggest that the contradictions of African American life in the post-Reconstruction world are parsed in the period's literature through the presence of a veiled georgic …

The Space Between, Aaron Joseph Mcelfish Jan 2014

The Space Between, Aaron Joseph Mcelfish

Electronic Theses and Dissertations

This series of abstracted landscapes is a visual representation of a challenge to step outside of my comfort zone. The paintings are an expression of emotions never before presented in the artist's work. The series expresses the visceral sensation of isolation, anger, and solace experienced throughout the creation of the work. The abstracted landscapes are an expression of the journey from anger and frustration to a path towards understanding and enlightenment. In the early stages, there were no tangible plans, just painting on tar-paper. The work then evolved to black and white latex paints built up over joint compound and …

The Effects Of Carbonated Soft Drinks On Bone Mineral Density In College Age Women, Tina Irene Bankston

Electronic Theses and Dissertations

Osteoporosis is a fast growing, worldwide public health problem. Also called, 'the silent disease' or 'fragile bone disease', osteoporosis results from low bone mass (Gammage & Klentrou, 2011; NOF, 2013; Swann, 2012). Currently, 44 million Americans have osteoporosis; 80% of which are women (NOF, 2011). Few studies, most implemented in other countries, have been conducted examining the consumption of carbonated soft drinks (CSD) as a risk factor for low bone mineral density (BMD) (Ogur et al., 2007; Hostmark et al., 2011; McGartland et al., 2003). The global consumption of CSDs increased by four percent during 2009 to 2010. Within the …

Stop Making Sense: Exploring Basic Properties And Clinical Applications Of Coherence, Michael James Bordieri Jan 2014

Stop Making Sense: Exploring Basic Properties And Clinical Applications Of Coherence, Michael James Bordieri

Electronic Theses and Dissertations

This study explored the ways in which people make sense of ambiguous tasks and the degree to which people prefer contexts where coherent responding is possible. Relational frame theory contains a foundational assumption that coherence (i.e., making sense) is reinforcing for verbally competent humans. That is, it is assumed that humans relate ambiguous stimuli in ways that go together because they have an extensive learning history where others have given praise, positive attention, and other reinforcement for this behavior. This study was designed to empirically investigate this core assumption of relational frame theory by analyzing response patterns to ambiguous stimuli …

Effects Of Nanosilver And Silver Nitrate Exposure On Fathead Minnows (Pimephales Promelas) And Zebrafish (Danio Rerio), Adam D. Hawkins Jan 2014

Effects Of Nanosilver And Silver Nitrate Exposure On Fathead Minnows (Pimephales Promelas) And Zebrafish (Danio Rerio), Adam D. Hawkins

Electronic Theses and Dissertations

Silver nanoparticles (AgNPs) due to their unique antimicrobial properties are among the most widely utilized nanoparticle. Because of the nature of the products that utilize AgNPs, environmental release of AgNPs is inevitable. At greatest risk is the aquatic ecosystem due to known toxicity of the Ag + ion to aquatic organisms. Our goal was to use two fish models, fathead minnows (Pimephales promelas; FHMs) and zebrafish ( Danio rerio; ZFs), to study the effects of AgNPs on gill histopathology, Na+/K+-ATPase immunoreactivity, mucus production, bioaccumulation, particle uptake characterization, gill gene expression, and lethality in varying water parameters in comparison to the …

Childhood Growth In An Oneota Community: Examining Long Bone Growth Differences In The The Juveniles At Norris Farms 36, Whitney Broughton Jan 2014

Childhood Growth In An Oneota Community: Examining Long Bone Growth Differences In The The Juveniles At Norris Farms 36, Whitney Broughton

Electronic Theses and Dissertations

Oneota migration into the central Illinois River valley around ad 1300 resulted in a number of different interactions with Mississippian groups. Milner and colleagues (1991) identified significant numbers of perimortem injuries at the Norris farms 36 cemetery, along with biological markers for poor health, such as cribra orbitalia and porotic hyperostosis. They suggested that the threat of violence may have forced the Oneonta at Morton village to limit subsistence activities to circumscribed areas close to the settlement, thereby reducing the resource base and negatively impacting the health of the community. However, recent research (Bengtson et al. 2012; Bengtson and O'Gorman …

Design And Analysis Of Reconfigurable Sensing Antennas For Wireless Sensing Applications, Qian Qiao Jan 2014

Design And Analysis Of Reconfigurable Sensing Antennas For Wireless Sensing Applications, Qian Qiao

Electronic Theses and Dissertations

Reconfiguration sensing antenna (rsa) is a novel antenna concept, which not only can transmit or receive radio waves but also can sense the surrounding environment. The environment sensing is realized by reconfiguring the antenna's characteristics, such as resonant frequency, and radar cross section (rcs). The rsas possess the advantages of passive and low cost, which make them suitable for the large-scale wireless sensing networks (wsns) deployment. In this dissertation, the rsas concept is demonstrated, and two sensing mechanisms performed in the rsas are investigated. In order to verify these sensing mechanisms, four rsas are designed, analyzed, and measured. All the …

The Origins Of An Everyday Behavior: Why Do People Share Meals?, David Lee Jan 2014

The Origins Of An Everyday Behavior: Why Do People Share Meals?, David Lee

Honors Theses

Humans are socially driven creatures that require constant interaction. One way humans have consistently expressed their social nature since prehistory is through sharing meals. Recent studies and literature were examined in order to investigate the roots behind why sharing meals has been the most consistent method of social output. Through careful reading and analysis, reasons behind why people share meals were traced in perspective levels. The biological and molecular aspect explains how humans evolved from prehistoric primates and their similarities associated with food consumption. Genetics and food preferences also play a role by allowing humans to taste food rather than …

Modeling Nitroglycerin-Induced Migraine In Rats, Stephanie Staszko Jan 2014

Modeling Nitroglycerin-Induced Migraine In Rats, Stephanie Staszko

Honors Theses

The present research sought to determine whether nitroglycerin (NTG) produced changes in clinically relevant endophenotypes of migraine. Rats were given a single injection of NTG or vehicle with the following dependent measures recorded: Rat Grimace Scale, hot and cold tail flick latency, Rotor-Rod performance, and photophobia and movement in traditional and modified light/dark boxes. NTG increased rat grimace scores but did not produce thermal allodynia nor photophobia. Further, NTG produced paradoxical increases in Rotor-Rod performance and movement. These results demonstrate that a single injection of NTG does not produce behaviors that parallel clinical symptoms of migraine.

The Effects Of Adrenergic Antagonists On Spatial Memory In The Zebra Finch (Taeniopygia Guttata), Taylor Williams Jan 2014

The Effects Of Adrenergic Antagonists On Spatial Memory In The Zebra Finch (Taeniopygia Guttata), Taylor Williams

Honors Theses

The adrenergic system appears to be involved in the consolidation and reconsolidation of hippocampally dependent spatial memories in mammals. Based on connectivity, cell types, ontogeny and receptor distribution, the avian hippocampus is thought to be a homolog to the mammalian hippocampus. The adrenergic system appears to be fairly conserved but may show some species specializations. To determine if the adrenergic system plays a role in spatial learning and memory in birds, we used a series of experiments to investigate the role of α- and β-adrenergic receptors on spatial navigation and memory in an avian species, zebra finches, using the Day …

An Evaluation Of Soil Extracellular Enzyme Activity In Response To Burning As A Forest Restoration Technique, William M. Steward Jan 2014

An Evaluation Of Soil Extracellular Enzyme Activity In Response To Burning As A Forest Restoration Technique, William M. Steward

Honors Theses

Burning is a method of forest restoration with the goal of returning natural tree species to ecosystems. Burning has a wide range of effects on an ecosystem, including the alteration of important soil processes and characteristics. One of the key components of soil is the activity of extracellular enzymes, which can be used to provide insight into the nutritional requirements of soil microbes as well as nutrient availability and cycling. Because enzymes are important in the overall functioning of soil and can be used to assess soil health, there is great need to examine the effects of burning on soil …

Boredom And Memory For Positively And Negatively Valenced Words, James Kirchner Jan 2014

Boredom And Memory For Positively And Negatively Valenced Words, James Kirchner

Honors Theses

The purpose of the present study was to determine whether boredom affected memory for positively and negatively valenced words in addition to class names (e.g., History) that were presented in an auditory modality while participants listened to a recorded script. This was accomplished by comparing the recall of a doodling group, who were asked to shade in shapes while listening to a recorded script, with a non-doodling group, who simply listened to the script. The results indicated that participants in the non-doodling group recalled more class names (e.g. History) from the script than participants in the doodling group. In addition, …

Promotion Of Environmental Engagement Through Positive Youth Development In Tanzania, Katherine Westfall Jan 2014

Promotion Of Environmental Engagement Through Positive Youth Development In Tanzania, Katherine Westfall

Honors Theses

With climate change and environmental degradation already having devastating effects on communities in sub-Saharan Africa, enhancing youth's commitment to the environment and mobilizing their pro-environmental action is increasingly urgent. In this study, we explored predictors of environmental commitment and action based on a model of positive youth development. We predicted that sociodemographics, self-efficacy, connection to nature, sense of community, and club participation would predict environmental commitment and action. Tanzanian youth (N = 959) from regions across the country completed self-report measures assessing these constructs. Using a series of logistic and hierarchical multiple regressions, we were able to predict statistically significant …

An Investigation Of The Effects Of Hysteresis On The Rotation Percept, Maximilian James Shumake Jan 2014

An Investigation Of The Effects Of Hysteresis On The Rotation Percept, Maximilian James Shumake

Honors Theses

Although much research has been done on the role of hysteresis in apparent motion displays, no research has investigated the effects of hysteresis for rotary motion. The present experiment sought to determine and quantify the effects of hysteresis on the rotation percept. Participants viewed two types of apparent motion stimuli, which consisted of tokens appearing to move in a clockwise, counterclockwise, or chaotic fashion. One of the displays slowly changed from favoring a percept of rotation to a percept of non-rotation and vice versa. We fit the data using a logistic function and compared the point at which the direction …

The Effect Of Sumatriptan On Clinically Relevant Behavioral Endpoints In A Recurrent Nitroglycerin Migraine Model In Rats, Morgan Elizabeth Davis Jan 2014

The Effect Of Sumatriptan On Clinically Relevant Behavioral Endpoints In A Recurrent Nitroglycerin Migraine Model In Rats, Morgan Elizabeth Davis

Honors Theses

The present research sought to determine the effects of sumatriptan on clinically relevant behavioral endpoints in migraine produced by repeated nitroglycerin (NTG) administrations in rats. Rats were given 5 NTG administrations each of which was followed by either saline, 0.3 mg/kg sumatriptan, or 1.0 mg/kg sumatriptan over a 2-week period. During their 5th NTG migraine episode, behavioral endpoints were the Rat Grimace Scale, photophobia, and movement. Sumatriptan dose dependently attenuated a) loss in weight, b) elevated Rat Grimace Scale pain scores, and c) decreased movement in the modified light-dark box. In addition, rats with the highest dose of sumatriptan tended …

Down Creek A Screenplay, Elizabeth Britt Mcclure Jan 2014

Down Creek A Screenplay, Elizabeth Britt Mcclure

Honors Theses

Growing up, the story was told to me this way: one day, a little boy’s foot washed up on a beach in Charleston. An investigation found that the foot belonged to a patient of Dr. Reed, an orthopedic surgeon who had removed the boy’s foot some three years prior. The doctor had stored the boy’s foot in his freezer at home. When one day the freezer broke down. Dr. Reed disposed of the body part by substituting it for raw chicken in his crab trap. Somehow the foot escaped the bait compartmentmuch to the leathery beachgoers’ horror. Even as a …

Certified Personal Trainers And Physicians: An Evaluation Of Consumer Preference, Influence, And Decision Making On Intent To Use A Weight-Loss Medication, Linda Lemgruber Lobb Jan 2014

Certified Personal Trainers And Physicians: An Evaluation Of Consumer Preference, Influence, And Decision Making On Intent To Use A Weight-Loss Medication, Linda Lemgruber Lobb

Electronic Theses and Dissertations

In health-related behavioral decision-making, the Theory of Planned Behavior (TPB) posits that attitudes toward a behavior are the function of three metrics: beliefs and strengths of beliefs toward the behavior, subjective norms around the behavior and locus of control for the individual (Ajzen, 1988). The purpose of this research was to identify the extent to which consumers would accept the recommendation of taking weight-loss medications, based on the source of the recommendation. Research shows that the source of knowledge for information plays a significant role in health-related decision-making of consumers (Pornpitakpan, 2004). In comparison to traditional weight-loss methods such as …

The Efficacy Of Prostaglandin Synthase Inhibition On Attenuating Pressure Overload Induced Cardiac Remodeling, Krishna T. Nagalla Jan 2014

The Efficacy Of Prostaglandin Synthase Inhibition On Attenuating Pressure Overload Induced Cardiac Remodeling, Krishna T. Nagalla

Electronic Theses and Dissertations

Chronic hypertension has long been known to cause left ventricular remodeling. Although previous studies pointed towards inflammation as the pathological driver of cardiac remodeling, the exact mechanistic pathway associated with pressure overload-induced cardiac remodeling remains to be elucidated. In order to address this issue, we designed this study to determine pathways associated with pressure overload induced cardiac remodeling and identify therapeutic targets to attenuate this maladaptive cardiac remodeling. Rats with surgically constricted abdominal aorta were used as an animal model for pressure overload and associated Left ventricular (LV) structure and functional changes were measured by pressure-volume admittance catheterization. Human cardiac …
