Head-Start Juvenile And Adult Resident Eastern Box Turtles (Terrapene Carolina Carolina): Winter Ecology Including Microhabitat Selection, Temperature Tolerance And Philopatry, Amberly Moon

Theses and Dissertations

The Eastern box turtle (Terrapene carolina carolina) is one of the most common reptiles in North America, but is soon to be threatened due to increased urbanization, disease, and the pet and food trades. In order to assist resource managers in choosing suitable sites for relocation studies, more information on the winter ecology of this species is necessary. We examined the temperature tolerance, microhabitat and degree of philopatry to hibernacula for juvenile and adult E. box turtles for two consecutive winters in Charles City Co, VA. The turtles were tracked via radio telemetry to record point locations during the active …

Hindfoot And Forefoot Kinematic Differences Among Individuals With And Without Functional Ankle Instability, Cynthia Wright

Theses and Dissertations

Introduction: Following lateral ankle sprain, many individuals experience recurrent injury and symptoms of giving-way, known as Functional Ankle Instability (FAI). It has been proposed that altered joint kinematics during activity may contribute to instability in these individuals, however research findings have been inconsistent. Objective: To capture foot and ankle kinematic data during two common tasks (walking gait and jump landing) among three groups: individuals with FAI, healthy controls and copers. Design: 3-group observational cross-sectional study. Participants: Participants included 23 individuals with a history of ≥ 1 ankle sprain and at least 2 episodes of giving-way in the past year (FAI: …

Pediatrician Perceptions Of The Patient-Centered Medical Home Model, Christopher Ray

Theses and Dissertations

The Patient-Centered Medical Home (PCMH) is an emerging model of health care designed to provide a simpler, more effective health care experience. The model places heavy emphasis on the concept of every patient having a "personal physician" who is the point of access for all health care needs and concerns. The personal physician integrates all relevant health care information to provide the patient with a holistic picture of his health. The supposed benefits of the PCMH model include an improved patient experience, increased effectiveness of care, increased efficiency of care, greater access to care, among others. Only now is evidence …

Functional Consequences Of Cytosine Methylation In Mitochondrial Dna Catalyzed By Dna Methyltransferase 1, Lisa Shock

Theses and Dissertations

Cytosine methylation of mitochondrial DNA (mtDNA) was first described several decades ago, but neither the mechanism generating this modification nor its functional significance was known. Because mitochondrial dysfunction is a hallmark characteristic of numerous human diseases, including neurological and cardiovascular disease, aging and cancer, this dissertation addressed whether epigenetic modification of mtDNA regulates mitochondrial function. We show that mtDNA contains not only 5-methylcytosine (5mC), but also 5-hydroxymethylcytosine (5hmC), suggesting that previous reports likely underestimated the degree of epigenetic modification within the mitochondrial genome. We questioned how these modifications were generated by looking for mitochondrial isoforms of the nuclear-encoded DNA methyltransferases. …

Data Compressive Paradigm For Multispectral Sensing Using Tunable Dwell Mid-Infrared Detectors, Woo-Yong Jang, Majeed M. Hayat, Sebastian E. Godoy, Steven C. Bender, Payman Zarkesh-Ha, Sanjay Krishna

Electrical and Computer Engineering Faculty Research and Publications

While quantum dots-in-a-well (DWELL) infrared photodetectors have the feature that their spectral responses can be shifted continuously by varying the applied bias, the width of the spectral response at any applied bias is not sufficiently narrow for use in multispectral sensing without the aid of spectral filters. To achieve higher spectral resolutions without using physical spectral filters, algorithms have been developed for post-processing the DWELL’s bias-dependent photocurrents resulting from probing an object of interest repeatedly over a wide range of applied biases. At the heart of these algorithms is the ability to approximate an arbitrary spectral filter, which we desire …

Home Literacy Factors Affecting Emergent Literacy Skills, Robyn Valerie Cassel

Theses and Dissertations

The purpose of this study is to identify factors in the home literacy environment using the Stony Brook Family Reading Survey (SBFRS) in order to understand the extent to which these factors predict phonemic awareness and other basic reading skills, as assessed by selected subtests from the Woodcock-Johnson III (WJ III). The present study used archival data to examine the home literacy habits of a sample of parents and preschool children ages 3-5 years (range in months= 36-67) from a private and a public preschool with a combination of high- and low-income backgrounds and various ethnicities. Using exploratory factor analyses …

What If Daniel Ellsberg Hadn't Bothered?, Heidi Kitrosser

Articles

This article was written for the Indiana Law Review’s 2011 annual symposium entitled, “What If? Counterfactuals in Constitutional History.” As the article’s title suggests, it considers the impact of Daniel Ellsberg’s decision to leak the Pentagon Papers to the New York Times. The article takes some liberty with the topic of constitutional counterfactuals. Despite its author’s vast enjoyment of several classic movies and television episodes featuring parallel worlds, the article does not build a counterfactual universe in which Daniel Ellsberg never leaked the Pentagon Papers. It hints at such a world indirectly, however, by considering the difference that Ellsberg’s leak …

Fiber-Reinforced Calcium Sulfate Bone Cement Composites With Enhanced Bioactivity, Mechanical Properties And Controlled Biodegradability, Nuha Fathi Hussien

Theses

Hard tissues are natural composites of inorganic and organic components. The inorganic component is a basic Calcium phosphate; known as hydroxyapatite (HAp) while the organic is a natural polymer; known as collagen. The interlocking between the collagen nanofibers and the Hap nanocrystals growing on them offers the known unique mechanical stability of hard tissues. In case of partial fractures; bone or dental cements are often used. Cements such as polymethylmethacrylate (PMMA) has been long used in this regard. However, this polymer is classified as a bio inert material that can be accepted by the human body without having a positive …

Magnetization Precession And Domain-Wall Structure In Cobalt-Ruthenium-Cobalt Trilayers, Zhen Li, Ralph Skomski, Sy-Hwang Liou, Steven Michalski, Mircea Chipara, Roger D. Kirby

Physics & Astronomy Faculty Publications

The magnetization dynamics of Co(5 nm)/Ru/Co(5 nm) trilayers with Ru thicknesses from 0.3–0.6 nm is experimentally and theoretically investigated. The coupling between the Co layers is antiferromagnetic (AFM) and yields a stable AFM domain structure with frozen domain walls. Comparing high-resolution magnetic force microscopy (MFM) and pump-probe measurements, we analyze the behavior of the films for different field-strength regimes. For moderate magnetic fields, pump-probe measurements provide dynamic characterization of the coupled precessional modes in the GHz range. The dynamics at small fields is realized by the pinning of AFM domain walls at inhomogeneities. The MFM images yield a domain-wall width …

The Behavior Of Nanothermite Reaction Based On Bi2o3/Al, L. Wang, D. Luss, Karen S. Martirosyan

Physics & Astronomy Faculty Publications

We studied the impact of aluminum particle size and the thickness of surrounding alumina layer on the dynamic pressure discharge of nanothermite reactions in the Bi2O3/Al system. A pressure discharge from 9 to 13 MPa was generated using as-synthesized Bi2O3 nano-particles produced by combustion synthesis and Al nanoparticles with size from 3 μm to 100 nm. The maximum reaction temperature was measured to be ∼2700 °C. The estimated activation energy of the reaction was 45 kJ/mol. A very large (several orders of magnitude) difference existed between the rate of the pressure pulse release by nanothermite reactions and by thermite …

Directional Limits On Persistent Gravitational Waves Using Ligo S5 Science Data, J. Abadie, B. P. Abbott, Matthew Benacquista, Teviet Creighton, R. Grosso, J. Li, Soma Mukherjee, Soumya Mohanty, Malik Rakhmanov, Volker Quetschke, Robert Stone, Joseph D. Romano, B. Vaishnav

Physics & Astronomy Faculty Publications

The gravitational-wave (GW) sky may include nearby pointlike sources as well as stochastic backgrounds. We perform two directional searches for persistent GWs using data from the LIGO S5 science run: one optimized for pointlike sources and one for arbitrary extended sources. Finding no evidence to support the detection of GWs, we present 90% confidence level (C.L.) upper-limit maps of GW strain power with typical values between 2−20×10−50  strain2 Hz−1 and 5−35×10−49  strain2 Hz−1 sr−1 for pointlike and extended sources, respectively. The latter result is the first of its kind. We also set 90% C.L. limits on the narrow-band root-mean-square GW …

Unidirectional Invisibility Induced By Pt-Symmetric Periodic Structures, Zin Lin, Hamidreza Ramezani

Physics & Astronomy Faculty Publications

Parity-time (PT) symmetric periodic structures, near the spontaneous PT-symmetry breaking point, can act as unidirectional invisible media. In this regime, the reflection from one end is diminished while it is enhanced from the other. Furthermore, the transmission coefficient and phase are indistinguishable from those expected in the absence of a grating. The phenomenon is robust even in the presence of Kerr nonlinearities, and it can also effectively suppress optical bistabilities.

Investigation Of In-Situ Stresses In Rocks Via Acoustic Emission And The Kaiser Effect., Derrick J. Blanksma

Undergraduate Theses and Senior Projects

This paper is a proposal for designing the Kaiser In‐Situ Stress (KISS) System. The KISS System’s goal is to determine in‐situ stresses in rock formations and other subsurface rocks by means of compression‐induced Acoustic Emission (AE) and the Kaiser effect. The KISS System is a non‐destructive method of in‐situ stress determination and has received much attention in the past. To fully understand AE, the Kaiser Effect and how it relates to stress determination this paper will present the necessary theoretical background, past experimentation and results from the authors own experimentation to investigate the plausibility of AE and the Kaiser Effect …

Responding To Our Own Transgressions: An Experimental Writing Study Of Repentance, Offense Rumination, Self-Justification, And Distraction, Charlotte Vanoyen-Witvliet, Nova G. Hinman, Julie J. Exline, Timothy Brandt

Faculty Publications

This between-subjects experiment focused on offender responses to their past interpersonal transgressions in self-identified Christian undergraduates (55 M, 85 F). Participants completed pre-post measures for one of four randomly assigned 20-minute writing conditions: repentance (i.e., writing about constructive sorrow, apology, restitution, behavior change), offense rumination (i.e., negative wallowing), self-justification (i.e., externalizing blame, minimizing costs), or distraction (i.e., daily details). Offense rumination and repentance writing included the most cost-oriented language; rumination had the most negative emotion language. Mixed within (pre vs. post) X between group ANOVA interactions yielded theoretically meaningful results. Repentance reduced self-condemnation and regret while increasing conciliatory motivations toward …

Neural Mechanisms Of Interference And Storage In Vibrotactile Working Memory, Tyler D. Bancroft

Theses and Dissertations (Comprehensive)

Vibrotactile working memory has attracted increasing attention in recent years. Substantial research into the neural correlates has been conducted, especially using single-cell paradigms in non-human primates (Romo & Salinas, 2003). The vibrotactile working memory system uses a relatively simple neural code for the representation of stimuli, making it possible to determine when stimulus information is present in the various cortical areas thought to be involved. In humans, vibrotactile working memory displays properties (such as overwriting mechanisms of interference) that make it an ideal system for testing general theories of working memory. In the present study, we demonstrate that vibrotactile working …

Exploring Perfectionism, Rumination And Social Anxiety: Theoretical And Causal Implications, Jaclyn R. Brown

Theses and Dissertations (Comprehensive)

Clark and Wells’ (1995) cognitive model of Social Anxiety (SA) posits that those with (SA) have a strong fear of negative evaluation and engage in excessive rumination following social interactions or performances. Fear of negative evaluation is also a key component of perfectionism; perfectionism has also been correlated with rumination. The purpose of the research was to examine the relationships among SA, rumination and perfectionism across two studies. For Study 1, participants were recruited (N=232) to complete online questionnaires. Psychometrics, including factor structure, were examined. It was expected that SA and rumination, rumination and perfectionism, and SA and …

Cd-Induced Responses In Plasma Ionic Regulation And Oxidative Stress In Rainbow Trout (O. Mykiss) Or Lake Whitefish (C. Clupeaformis) During Chronic Waterborne Exposure, Amanda Mancini

Theses and Dissertations (Comprehensive)

During chronic exposure to Cd or other metals, freshwater fish generally undergo physiological changes that results in acclimation, following a phase of damage and subsequent repair. The mechanisms associated with deleterious cellular effects induced by Cd throughout long-term exposures are less understood than those of acute toxicity, and may relate to an over-production of reactive oxygen species. The objectives of the present study were to examine the changes in, and relationship between, tissue-specific oxidative damage and antioxidant response, as well as plasma ionic regulation and tissue accumulation, in two freshwater salmonids throughout chronic Cd exposure. Rainbow trout (O. mykiss …

You Can’T Go To Zion With A Carnal Mind: Slackness And Culture In The Music Of Yellowman, Brent Hagerman

Theses and Dissertations (Comprehensive)

Jamaican deejay Yellowman is best known for “slackness” lyrics centred on masculine heterosexual potency, sexist objectification of women and graphic sexual narratives. Yet a deeper look at Yellowman’s life and recorded output suggests that when his slackness is read in the context of Afro-Jamaican culture, reggae history and his Rastafarian faith, a more complex interpretation of his slackness is needed. This study will draw on Carolyn Cooper’s (2001) theory that slackness is a “metaphorical revolt against law and order, an undermining of consensual standards of decency” (p. 141). Whereas the term “culture” is used in reggae to depict music that …

Effective Islamic Spiritual Care: Foundations And Practices Of Imams And Other Muslim Spiritual Caregivers, Nazila Isgandarova

Theses and Dissertations (Comprehensive)

In Canada, Muslim communities turn to Muslim spiritual caregivers, especially to imams, for help with various problems. Research has shown that many Muslim spiritual caregivers are familiar with the Arabic language and Islamic values but have limited practice in Islamic counseling and psychotherapy. This study is intended to examine the effectiveness of Muslim spiritual caregivers in the context of Canadian Muslims’ health care. Cross-sectional ethnographic research with fifteen Muslim spiritual caregivers and interviews with them were conducted.

Our results show that even though the majority of Muslim spiritual caregivers have no formal training in Western psychotherapy intervention, they nonetheless play …

Interface Between Black-Footed Ferret Research And Operational Conservation., Dean E. Biggins, Travis M. Livieri, Stewart W. Breck

United States Department of Agriculture Wildlife Services: Staff Publications

Questions and problems that emerged during operational conservation of black-footed ferrets (Mustela nigripes)have been addressed by a wide variety of studies. Early results from such studies often were communicated orally during meetings of recovery groups and in written form using memoranda, unpublished reports, and theses. Typically, implementation of results preceded their publication in widely distributed journals. Many of these studies eventually were published in journals, and we briefly summarize the contents of 8 volumes and special features of journals that have been dedicated to the biology of ferrets and issues in ferret recovery. This year marks the 30th anniversary of …

White-Tailed Deer Incidents With U.S. Civil Aircraft, Kirsten M. Biondi, Jerrold L. Belant, James A. Martin, Travis L. Devault, Guiming Wang

United States Department of Agriculture Wildlife Services: Staff Publications

Aircraft incidents with ungulates cause substantial economic losses and pose risks to human safety. We analyzed 879 white-tailed deer (Odocoileus virginianus) incidents with United States civil aircraft from 1990 to 2009 reported in the Federal Aviation Administration National Wildlife Strike Database. During that time, deer incidents followed a quadratic response curve, peaking in 1994 and declining thereafter. There appeared to be some seasonal patterning in incident frequency, with deer incidents increasing overall from January to November, and peaking in October and November (30.7%). Most incidents (64.8%) occurred at night, but incident rates were greatest (P 0.001) at dusk. Landing-roll represented …
