The Effect Of Various Pathologies On Bone Quality, Daniel S. Porter Jan 2014

The Effect Of Various Pathologies On Bone Quality, Daniel S. Porter

Theses and Dissertations--Biomedical Engineering

Bone’s ability to resist fracture is often ignored until a low-energy fracture occurs. Patients with Chronic Kidney Disease (CKD) or osteoporosis are at an increased risk of low-energy fracture. Generally, fracture risk is evaluated by using a bone mineral density (BMD) test. BMD values; however, do not fully predict bone’s ability to resist fracture. This suggests that other parameters may be involved. Bone quality is the term used to describe these parameters, which are categorized into three groups: structural, material, and microdamage. The aim of this dissertation research was to examine whether bone quality was altered in patients who: 1) …

Let’S Play: Understanding The Role And Significance Of Digital Gaming In Old Age, Julie A. Skalsky Brown Jan 2014

Let’S Play: Understanding The Role And Significance Of Digital Gaming In Old Age, Julie A. Skalsky Brown

Theses and Dissertations--Gerontology

Despite a marked increase in the use of digital games among older persons, there is insufficient research that provides insight into the gaming experiences of this population. A major demographic shift within the senior gaming market has ushered in a new perspective on the use of digital games as a tool for physical and cognitive health, and improved socialization. It is proposed that individual notions of play, which are developed over the life course, influence digital game play engagement and interaction preferences, and contribute to well-being. This study explored how self-perceptions of play over the course of the senior gamer’s …

Magic, Mimesis, And The Annunciation To Mary : Six Early Byzantine Cameos And The Late Antique Tradition Of Medical Amulets, Ashley A. Lee Jan 2014

Magic, Mimesis, And The Annunciation To Mary : Six Early Byzantine Cameos And The Late Antique Tradition Of Medical Amulets, Ashley A. Lee

Graduate Research Theses & Dissertations

It has been suggested by scholars that small portable objects from the early Byzantine period with the image of the Annunciation may have been used as fertility amulets, but none have examined this in detail. This thesis is the first detailed investigation of the possibility that six sardonyx cameos from sixth-seventh century Constantinople functioned as Christian fertility amulets. I propose that the cameos developed from the late antique tradition of gynecological amulets and could have been used as fertility amulets by women. The cameos emphasize Mary's position as a role model for women and encourage an act of mimesis. This …

Cultivating Primary Students’ Scientific Thinking Through Sustained Teacher Professional Development, Roxanne Greitz Miller, Margaret Sauceda Curwen, Kimberly A. White-Smith, Robert C. Calfee

Education Faculty Articles and Research

While the United States’ National Research Council (NRC 2012) and Next Generation Science Standards (NGSS 2013) advocate children’s engagement in active science learning, elementary school teachers in the US indicate lack of time to teach science regularly because of (1) school and district pressure to focus on English language arts and mathematics assessment scores in response to the country’s No Child Left Behind (2001) mandates; (2) a lack of preparation in teacher science content knowledge; and (3) a lack of science professional development opportunities. In response to these needs and focusing on the primary (Kindergarten–first–second) grade levels, the Project SMART …

Monitoring Ligand-Induced Nucleic Acid Conformational Changes Using Ion Mobility Spectrometry-Mass Spectrometry, Bill Kenneth Redick Jan 2014

Monitoring Ligand-Induced Nucleic Acid Conformational Changes Using Ion Mobility Spectrometry-Mass Spectrometry, Bill Kenneth Redick

Legacy Theses & Dissertations (2009 - 2024)

Three-dimensional structures of biopolymers frequently dictate the biological role those molecules play. As such, investigation into structure of nucleic acids can provide important information pertaining to how those nucleic acids work. Many nucleic acid species, especially single-stranded RNA, fold into unique structures that allow them to function properly. Metals, and other cationic species, are often bound to the nucleic acid to make folding into the proper structure more favorable by neutralizing the negative charge on the nucleic acid imparted by the phosphate group. This investigation explores tertiary structure of nucleic acids that have been folded in the presence of ligands …

Release From Proactive Interference : The Impact Of Emotional And Semantic Shifts On Recall Performance, Hugh Knickerbocker Jan 2014

Release From Proactive Interference : The Impact Of Emotional And Semantic Shifts On Recall Performance, Hugh Knickerbocker

Legacy Theses & Dissertations (2009 - 2024)

Proactive interference (PI) occurs when the recall of newly learned information is blocked by previously learned information (e.g., recalling an old list of food items when trying to recall a current list of food items during grocery shopping). Release from PI occurs when newly learned information is recalled without interference from previously learned information. Release from PI has been observed when making changes to the to-be-remembered items. Experiment 1 found significant release from PI when category shifted from a neutral category to an emotion category or an emotion-laden category. Experiments 2 and 3 compared the release from PI when shifting …

The Role Of Relational And Item Specific Processing In The Survival Advantage Across English And Spanish, Crystal J. Robinson Jan 2014

The Role Of Relational And Item Specific Processing In The Survival Advantage Across English And Spanish, Crystal J. Robinson

Legacy Theses & Dissertations (2009 - 2024)

The current paper examines the effects of survival processing relative to item specific and relational processing on recall for both English monolinguals and Spanish-English bilinguals. It has been suggested that both item specific and relational processing play an important role in the survival advantage (Burns, Hart, Griffith, & Burns, 2012; Burns, Hwang, & Burns, 2011). However, to date, the generalizability of this advantage has yet to be examined cross-linguistically. In two studies, participants were asked to make survival relevance ratings, pleasantness ratings, and to categorize a set of words from either common taxonomic or ad hoc categories. Spanish-English bilinguals performed …

Examining The Relations Between Disgust, Fear, And Eating Disorder Symptomatology, Lisa Marie Anderson Jan 2014

Examining The Relations Between Disgust, Fear, And Eating Disorder Symptomatology, Lisa Marie Anderson

Legacy Theses & Dissertations (2009 - 2024)

Exposure interventions for eating disorders typically identify fear as a key treatment target (i.e., fear of fat) and integrate a hierarchical list of the patient's fears into treatment. Recently, research has suggested that the disgust emotion may be equally important for exposure efficacy, as it appears to be more resistant to extinction than fear. Currently, the independent contributions of fear and disgust to eating pathology are unknown, which may limit our ability to develop and implement the most effective exposure interventions. Thus, the current study employed hierarchical multiple regression analyses to evaluate each emotion's relative contribution to eating disorder symptoms …

Regulation Of Ty1 Retrovirus-Like Transposon Rna Localization And Translation, Ryan Joseph Palumbo Jan 2014

Regulation Of Ty1 Retrovirus-Like Transposon Rna Localization And Translation, Ryan Joseph Palumbo

Legacy Theses & Dissertations (2009 - 2024)

Replication of the Ty1 retrovirus-like transposon of the yeast Saccharomyces cerevisiae is stringently regulated to reduce the frequency of deleterious retrotransposition events. However, under stress conditions, Ty1 retrotransposition can lead to adaptive genomic alterations. To characterize host regulation of Ty1 retrotransposition, I analyzed ribosome profiling data and showed that Ty1 RNA is efficiently translated. Moreover, the ribosome biogenesis factors BUD21, DBP7, HCR1, LOC1, MRT4, and PUF6 are required for optimal expression of the Ty1 protein Gag.

Queer Bodies And Queer Materials In Post-Wwii American Texts, William Joseph Whalen Jan 2014

Queer Bodies And Queer Materials In Post-Wwii American Texts, William Joseph Whalen

Legacy Theses & Dissertations (2009 - 2024)

Although the primary subject of this dissertation is contemporary American literature and popular culture--individual chapters are devoted to careful studies of Octavia Butler's short story "Bloodchild," Cormack McCarthy's gothic novel Child of God, Chuck Palahniuk's epistolary novel Pygmy, and the track "It's Good" by hip-hop artist Lil Wayne featuring Drake and Jadakiss--I develop a reading of these contemporary texts that places them within much older and richer intellectual, spiritual, psychological, and even biological traditions. My primary focus is the human body, both literal and figurative, as the site of dynamic exchanges, movements, blockages, and productive potentialities. I argue that at …

Military Contamination And Persistent Organochlorine Pesticide Exposure Among Alaska Natives, Samuel Byrne

Legacy Theses & Dissertations (2009 - 2024)

St. Lawrence Island Alaska is located in the Bering Sea, only 36 miles from Siberia. The island is home to approximately 1600 Siberian Yupik residents, who rely heavily on subsistence hunting and gathering. There are two formerly used defense (FUD) sites on the island, one of which has been the subject of an approximate $110 million cleanup effort. Environmental monitoring suggests localized soil and watershed contamination with PCBs, organochlorine pesticides and heavy metals. Previous research suggests the site may be a source of PCB exposure for local residents. The primary aim of the study was to determine whether subsistence activities …

Spinal Transection Changes External Urethral Sphincter Muscle Activity And Motoneuron Properties : Implications For Lower Urinary Tract Function After Spinal Cord Injury, Brandon Keith Lapallo Jan 2014

Spinal Transection Changes External Urethral Sphincter Muscle Activity And Motoneuron Properties : Implications For Lower Urinary Tract Function After Spinal Cord Injury, Brandon Keith Lapallo

Legacy Theses & Dissertations (2009 - 2024)

Lower urinary tract (LUT) dysfunction is a major problem for people with spinal cord injury (SCI). SCI impairs the reciprocal coordination of the two main LUT functional components: the bladder, a storage reservoir for urine; and the external urethral sphincter muscle (EUS), which regulates the passage of urine through the urethra. This impairment frequently results in detrusor-sphincter dyssynergia (DSD), a dangerous condition in which involuntary EUS contraction prevents voiding of urine from the bladder. Despite the critical role of the EUS during normal function and in DSD, studies of the contribution of SCI-induced EUS motoneuron abnormalities to EUS and LUT …

Motives, Reasons, And Morality : The Humean Theory Of Motivation, Reasons Internalism, And The Problem Of Objective Morality, Elliot Cross Jan 2014

Motives, Reasons, And Morality : The Humean Theory Of Motivation, Reasons Internalism, And The Problem Of Objective Morality, Elliot Cross

Legacy Theses & Dissertations (2009 - 2024)

In this dissertation I argue that the Humean theory of motivation, and reasons internalism ought to be accepted and are compatible with moral objectivity. The Humean theory of motivation is the view that only desires, and not beliefs, are capable of motivating. Reasons internalism is the view that only those considerations capable of motivating can be reasons. The combination of these two views entails that we only have a reason for action when we have a relevant desire. Accordingly, if we hold both of these positions then we cannot have reason to be moral unless we desire to be moral. …

Conservation Solutions To Shark Finning : Insights From Past Efforts, Jamie Zaccaria Jan 2014

Conservation Solutions To Shark Finning : Insights From Past Efforts, Jamie Zaccaria

Legacy Theses & Dissertations (2009 - 2024)

Globally, shark species are in decline, largely due to shark finning. This practice has an adverse effect on shark populations and could result in fishery and ecosystem collapses. Past conservation efforts, including the dolphin-safe tuna campaign, large mammal poaching, sea turtle conservation and the anti-whaling campaign, have used various approaches to mitigate impacts on wildlife, including political, consumer and public awareness, and science or evidence-based approaches. By examining and drawing from these processes we can determine the most effective strategy to reduce the effects of finning on shark populations around the world. A feasible conservation strategy for shark conservation in …

Critique Is Not Enough : The Empirical Imperatives Of Innovative American Poetry, Christopher Rizzo Jan 2014

Critique Is Not Enough : The Empirical Imperatives Of Innovative American Poetry, Christopher Rizzo

Legacy Theses & Dissertations (2009 - 2024)

Critique is Not Enough: The Empirical Imperatives of Innovative American Poetryproposes that innovative modern and early contemporary American poetries redefine the relation of knowledge, consciousness, and poetic performance to lived experience. This study demonstrates how the radically different poetic projects of Walt Whitman, Gertrude Stein, Ezra Pound, and Charles Olson not only equally insist upon empirically investigative poetics, but also endeavor, each to each, to individualize their poetic methodologies, which thus challenges the generalized Enlightenment myth of rationality. In that each of these writers undertakes to redefine the relation of knowledge, consciousness, and poetic performance to lived experience, they also …

Mediation Of Recurrent Hypoglycemia's Physiological And Behavioral Effects In The Hippocampus By Glucocorticoids, Danielle Osborne Jan 2014

Mediation Of Recurrent Hypoglycemia's Physiological And Behavioral Effects In The Hippocampus By Glucocorticoids, Danielle Osborne

Legacy Theses & Dissertations (2009 - 2024)

Recurrent hypoglycemia (RH) occurs with the over administration of insulin resulting in severe hypoglycemia on a repetitive basis. This occurs most commonly among Type I Diabetics who rely on exogenous insulin replacement for management of their disease; however it is becoming increasingly common among Type II Diabetics. Although cognitive deficits are reported during hypoglycemia, the period following restoration of euglycemia has been denoted by improved hippocampally-mediated short-term and working memory in humans and rodents, respectively. RH is also associated with an altered glucocorticoid secretion profile in response to hypoglycemia. In vitro and in vivo approaches were utilized with the goal …

A Biocultural Perspective On The Transition To Agriculture In Ukraine, Jordan Kenneth Karsten Jan 2014

A Biocultural Perspective On The Transition To Agriculture In Ukraine, Jordan Kenneth Karsten

Legacy Theses & Dissertations (2009 - 2024)

The development of agriculture and its spread around the globe is one of the most consequential events in the history of our species. The transition to agriculture is associated with many cultural developments, such as craft specialization, urbanization, and the creation of social hierarchies. Many social theorists believe that these changes associated with the adoption of farming were beneficial to the human condition, however, not all agree. The goal of this research is to evaluate the impact of the adoption of agriculture on human health. To do this, bioarchaeological analysis is employed, comparing the skeletal and dental health of Mesolithic …

Probing Secondary And Tertiary Rna Folding Using Force And Temperature, William Stephenson Jan 2014

Probing Secondary And Tertiary Rna Folding Using Force And Temperature, William Stephenson

Legacy Theses & Dissertations (2009 - 2024)

RNA folding is the process whereby a single stranded RNA molecule assumes its three-dimensional functional conformation. Along with the protein folding problem, the RNA folding problem remains as one of the great unsolved problems in biophysics. Generally RNA folding occurs in a hierarchical manner whereby the sequence of an RNA (primary structure) determines which regions will form helical segments (secondary structure) before further rearrangement and base pairing of secondary structure motifs (tertiary structure). Due to the intimate connection between structure and function within molecular biology, increased familiarity with the thermodynamic and kinetic factors that govern RNA folding will permit the …

Effects Of Extreme Hydrologic Events On Trout Populations And Fish Communities In A Catskill Mountain River, Scott Daniel George Jan 2014

Effects Of Extreme Hydrologic Events On Trout Populations And Fish Communities In A Catskill Mountain River, Scott Daniel George

Legacy Theses & Dissertations (2009 - 2024)

Extreme hydrologic events are becoming more common with changing climatic conditions. Although the impacts of winter and spring floods on lotic ecosystems have been well studied, the effects of summer floods on fish assemblages in mountain streams are less well known. This study took advantage of an extreme precipitation event during the course of an ongoing monitoring program, which allowed the opportunity to quantify the effects of a severe late summer flood on fish communities in a montane watershed. We also evaluated the effect of the flood on the density and age structure of two ecologically important populations of sport …
