Changing Cigarette Consumption Patterns And Their Relationship To Tobacco Control Policies In A Population Of Low-Intensity Smokers, Santosha Kamala Swayampakala

Theses and Dissertations

Tobacco use is the single most preventable cause of premature death and disability in the world. Every year six million people will die from tobacco-related diseases. To curb the growing tobacco epidemic, World Health Organization (WHO) adopted its first-ever global public health treaty, Framework Convention on Tobacco Control (FCTC) that obligates ratifying countries to implement a range of tobacco control policies. Most of the evidence for the effectiveness of the WHO’s FCTC recommended tobacco control policies comes from high-income countries (HICs). This evidence suggests that as smoking prevalence declines in response to tobacco control policies and programs, the proportion of …

Addressing Disparity: One Unique School’S Efforts To Provide Holistic Education In A Low-Income, Black Community, Allison Anne Parsons

Theses and Dissertations

Schools are meant to provide an equal opportunity for achievement to all students. The reality is that school policies and practices, which govern not only child education but also child health, parenting practices, and other social issues, are based on ideologies of the dominant culture creating an environment the perpetuates current social hierarchies. By doing so, this not only limits minority populations’ access to the opportunities associated with education but also access to health, as education and health are strongly and positively linked.

This study used qualitative methods including ethnography to explore how racism was perpetuated through the dominant discourses …

Study 1 examined task-related changes in eye movements for scene search, scene memorization, text-reading, and pseudoreading. Ex-Gaussian, analysis of variance, and correlational analyses were used to compare differences in eye movements across tasks and participant groups. Study 2 examined how oculomotor and linguistic processing influence eye movements for textreading and pseudo-reading. In addition to the statistical analyses used in Study 1, four case studies were carried out …

The Influence Of Warmth And Competence Perceptions On Employees’ Attitudinal And Behavioral Responses In Casual Dining Restaurants, Diego Riva Humbert Bufquin

Theses and Dissertations

Employees in the hospitality industry continuously judge their peers and leaders in order to evaluate their work environment. Group and individual evaluations are systematic, as the restaurant industry is characterized by high labor intensiveness that typically involves substantial social interactions and task interdependence. As a consequence, employees come up with quick and broad conclusions about the characteristics of the people that they work with or for.

Along these lines, two of the most significant constructs that govern the social perceptions or evaluations of individuals and groups are people’s perceived warmth and competence. The warmth construct informs people whether a person …

Knowing In America: The Enlightenment, Science, And The Early Republic, Timothy K. Minella

Theses and Dissertations

This dissertation analyzes practices of science and technology in the early United States as windows onto the American Enlightenment. Although scholars have emphasized the important impact of Enlightenment thought on the American founding, the historiography tends to argue for the decreasing influence of the Enlightenment on American culture as the nineteenth century progressed. In addition, scholars tend to see a decline in American science after Benjamin Franklin as nineteenth-century Americans began to focus primarily on the practical problems of everyday life. I question these interpretations by connecting scientific practice in the Early Republic with transatlantic Enlightenment thought and analyzing American …

Species Responses To Climate Change And Environmental Heterogeneity: A Multi-Focal Approach, Megan Riley

Theses and Dissertations

Changes in global climate trends have the potential to influence diverse ecosystems at multiple levels of organization, from the species to the community. Changes in other environmental variables, such as those resulting from pollution and habitat modification, also have the potential to impact species fitness and alter species interactions. This dissertation employs a multi-focal approach to investigate species responses to two main topics: climate change and environmental heterogeneity. To investigate the first topic, this work focuses on the climate change-induced range expansion of the mangrove tree crab Aratus pisonii into novel salt marsh habitats. It investigates latitudinal patterns of life …

Toward The Combinatorial Limit Theory Of Free Words, Danny Rorabaugh

Theses and Dissertations

Free words are elements of a free monoid, generated over an alphabet via the binary operation of concatenation. Casually speaking, a free word is a finite string of letters. Henceforth, we simply refer to them as words. Motivated by recent advances in the combinatorial limit theory of graphs–notably those involving flag algebras, graph homomorphisms, and graphons–we investigate the extremal and asymptotic theory of pattern containment and avoidance in words.

Word V is a factor of word W provided V occurs as consecutive letters within W. W is an instance of V provided there exists a nonerasing monoid homomorphsism phi with …

The Recovery Of Gut Barrier Function With Selenium Rich Diet In Acute Dss-Induced Colitis, Sarah Depaepe

Theses and Dissertations

Background: Acute Dextran Sodium Sulfate (DSS)-induced colitis is an inflammatory ailment limited to the colon. It works to destroy the morphology and gut barrier goblet and epithelial cells that aid in providing homeostasis. Selenium (Se) is an essential micronutrient that has anti-inflammatory and antioxidant properties and is known to play a role in reducing inflammation in areas elsewhere in the body. The current study is focused on how Se alters gut barrier permeability and functionality related to the recovery of tight junction regulation and mucin secretion. Methods: C57BL/6 mice were randomly placed into control (normal water) and 2% DSS water …

Assessing The Magnitude And Impact Of Seawater/Pore Water Exchange In Salt Marsh Systems, Carrie Lee Milliken

Theses and Dissertations

Submarine groundwater discharge is a hydrological process that is important to study and understand as it impacts biogeochemical processes and hydrological cycles. Particularly in coastal salt marsh systems, it is an important process to analyze as these systems serve as crucial interfaces between terrestrial and marine waters and particulates. There is evidence that these systems, typically thought to have little exchange across the interface due to impermeable sediments, could actually allow for significant flow of water and particulates at shallow depths. In order to measure and quantify this flow, a method using 224Ra as a tracer has been tested. The …

Trees, Partitions, And Other Combinatorial Structures, Heather Christina Smith

Theses and Dissertations

This dissertation contains work on three main topics.

Chapters 1 through 4 provide complexity results for the single cut-or-join model for genome rearrangement. Genomes will be represented by binary strings. Let S be a finite collection of binary strings, each of the same length. Define M to be the collection of medians – binary strings μ which minimize Sigma v belongs to S H(μ,v) where H is the Hamming distance. For any non-negative function f(x), define Z(f(x), S) to be (Sigma μ belongs to M) (Pi v belongs to S)f(H(μ,v)). We study the complexity of calculating Z(f(x), S), with respect …

The Development Of Efficient Geminal-Based Methods For Quantum Chemical Calculations, Brett Allen Cagg

Theses and Dissertations

Incorporation of electron correlation to improve the accuracy of computations remains a driving force in quantum chemical method development. Traditionally, electron correlation effects are divided into static and dynamic correlation parts, and the inclusion of both results in methods that are impractical for large chemical systems. The goal of this doctoral research is to develop a method that efficiently accounts for both components of electron correlation in a separate but balanced manner. The approach focuses on combining a geminal method, called the antisymmetrized product of singlet-type, strongly orthogonal geminals (SSG), with dynamic correlation by either density functionals or a recently …

Correlations Between White Matter Integrity, Structural Connectivity, And Upper And Lower Extremity Motor Function In Individuals With Chronic Stroke, Denise M. Peters

Theses and Dissertations

Great variability is seen in the clinical manifestation of and recovery from stroke. Structural abnormalities often extend beyond the infarction site, indirectly affecting nonlesioned areas which can further contribute to motor deficits. Advances in neuroimaging have enabled the examination of white matter integrity and anatomical connectivity within the brain. Evidence is limited, however, regarding the relationship between the structural integrity and connectivity of primary and secondary motor tracts/brain regions and chronic upper and (especially) lower extremity motor impairments post-stroke. Therefore, the current study examined the relationship between upper/lower extremity motor impairments and structural integrity (Aim 1) and connectivity (Aim 2) …

Environmental Exposures And Childhood Pulmonary Function, Pallavi Prakash Balte

Theses and Dissertations

Fetal origins of adult disease hypothesis states that adverse influences early in developmental period and particularly during intrauterine life can result in permanent changes in physiology which may lead to increased disease risk of chronic diseases in adulthood. Both fetal and adolescent period are critical time periods for development of lungs. Any adverse environmental exposures during these critical periods of lung growth is a form of programming which can have long term effects on pulmonary function. The purpose of this dissertation was to examine the association between different environmental exposures and pulmonary function in children and late adolescents. The first …

Statewide Scale-Up Of Group Prenatal Care In South Carolina, Kristin M. Van De Griend

Theses and Dissertations

Background: Poor birth outcomes and racial disparities in birth outcomes in South Carolina are widely recognized problems. To improve maternal and child health outcomes, especially among vulnerable groups, universal access to timely, appropriate, and effective care should remain a priority through increased availability and accessibility. An interagency collaborative in South Carolina expanded CenteringPregnancy (CP) from two to five medical practices throughout the state. CenteringPregnancy is associated with improved birth outcomes and reduced rates of racial disparities in preterm birth throughout the United States. Important questions in the literature remain about strategies and determinants of scaling up sexual and reproductive …

Preservice Physical Education Teacher’S Value Orientations Across The Student Teaching Semester, Heesu Lee

Theses and Dissertations

It is of interest to physical education teacher educators to prepare pre-service teachers (PTs) to promote learning based on the five National Standards for K-12 Physical Education (NASPE, 2013). These National Standards reflect value orientations. However, limited empirical evidence exists that examines what value orientations PTs endorse and how physical education teacher education (PETE) programs influence their value orientations. The purpose of this study was to 1) examine the initial value orientations of PTs at entry into the course of student teaching, 2) describe how their value orientations change/develop and/or are maintained across the course, and 3) explore factors that …

The Role Of Intermembrane Space Redox Factors In Glutathione Metabolism And Intracellular Redox Equilibrium, Hatice Kubra Ozer

Theses and Dissertations

The mitochondrial intermembrane space (IMS) is a unique subcellular compartment that houses key thiol-dependent redox pathways such as protein transport, mitochondrial respiration, and detoxification of ROS (reactive oxygen species). These pathways are all dependent on cysteine-rich proteins, thus maintaining thiol-disulfide balance in this organelle is crucial for cellular functions. An IMS protein import pathway called the Mia40-Erv1 disulfide relay system uses disulfide bond formation for the import and retention of substrate proteins in the IMS. Erv1 is also suggested to be involved in maturation of cytosolic Fe-S cluster proteins and regulation of iron homeostasis in S. cerevisiae. However, these studies …

Mindfulness And Cognitive Aging, Elise J. Herndon

Theses and Dissertations

Mindfulness meditation involves the cultivation of a focused, pre-conceptual consciousness that enables increased present-centered awareness of internal states, cognitive processes, and external stimuli (Mikulas, 2011; Kornfield, 2010). Studies suggest that mindfulness practice affects the brain structures and cognitive processes related to fluid intelligence, and may affect fluid intelligence itself among highly experienced practitioners (e.g., Gard, Taquet, et al., 2014; Lazar et al., 2005; Ritskes et al., 2003). Fluid intelligence includes higher-order reasoning and problem-solving abilities that are independent of cultural and environmental influences. These abilities peak in young adulthood, then begin to decay (Cattell, 1987; Goldberg, 2005).

The current study …

Beyond Grades: The Impact Of Race And Academic Disidentification On Social Functioning And Academic Outcomes Among At-Risk High School Students, Brian K. Colar

Theses and Dissertations

An extant literature has supported the notion that black students perform poorly in comparison to white students on frequently used indicators of academic functioning, known as the academic gap between races. Although previous studies have identified this academic inequity between White and Black high school students, there is a dearth of literature examining the context and processes which may contribute to this gap. The current study further examines this educational disparity by evaluating the role of students’ social functioning, the impact of race, and academic outcomes among at-risk high school students. Although analytical evidence reports a positive correlation between social …

Iii-V Nitride Based Microcantilever Heaters For Unique Multimodal Detection Of Volatile Organic Compounds At Low Temperature, Ifat Jahangir

Theses and Dissertations

Detection of volatile organic compounds (VOCs), which are widely used in industrial processes and household products, is very important due to significant health hazards associated with them. VOCs are commonly detected using photo-ionization detectors (PIDs), suspended hot bead pellistors, or heated metal oxide semiconductor functionalization layers. However, these techniques used for detecting VOCs often suffer from one or more of the following issues - high power consumption, limited selectivity, complicated functionalization technique and expensive characterization tools. On the other hand, microcantilevers offer excellent avenues for molecular sensing that arises out of their high sensitivity to various physical parameter changes induced …

Theses and Dissertations

This study of Carl Friedrich Zelter’s Kantate auf den Tod Friedrichs marks the first scholarly and musical exploration of the piece since the eighteenth century. A handcopied score of the cantata was converted into modern notation in 2009 using the program Sibelius. This version of the score, as well as instrumental parts, was used for the lecture-recital that grew from the study of this work. The manuscript’s present-day owner, Renate de La Trobe of Hamburg, Germany, granted access to a fair copy of the original score with a dedication in Zelter’s own hand. A member of Mrs. de La Trobe’s …

Tropes Of Blood, Body And The Ground Of The Law: Becoming, Being And Beyond Wife On The Early Modern Stage, Emily Faye Murray

Theses and Dissertations

This project focuses on the representation of women on the early modern stage in three exemplary texts: the anonymous domestic tragedy Arden of Faversham, and two city comedies, Thomas Dekker’s The Shoemaker’s Holiday and Dekker and Thomas Middleton’s The Roaring Girl. Whether playing the role of adulterous wife, performing the role socially striving wife, or resisting the role of laboring wife, these female characters were on stage not only for entertainment, but also for examination and scrutiny by an early modern audience. Playwrights used characterizations of women and wives and their relationships to the economy as vehicles through …

Rule 9011(b) of the Federal Rules of Bankruptcy Procedure, the bankruptcy counterpart to Rule 11 of the Federal Rules of Civil Procedure (“Rule 11”), provides, that in presenting a pleading to the court, an attorney or unrepresented party is certifying that to the best of the person’s knowledge, information, and belief, formed after an inquiry reasonable under the circumstances, that: (1) it is not being presented for any improper purpose, such as to harass or to cause unnecessary delay or needless increase in the cost of litigation; (2) the claims, defenses, and other legal contentions therein are warranted by …

The Earmarking Doctrine: Can It Be Used To Protect Late-Recorded Mortgages In Preference Action?, Michael Benzaki

Bankruptcy Research Library

(Excerpt)

Borrowers often seek to refinance their home loan mortgages in order to attain more favorable interest rates and other terms. Essentially, in these refinancing transactions, “the parties are looking simply to exchange one more expensive secured loan for another less expensive secured loan.” Typically, as part of the transaction, a refinancing lender will discharge the original mortgage and record a new mortgage. It is not uncommon for a delay to occur such that the new mortgage is recorded over thirty days after the lender transferred the funds to pay off the original loan. In such a case, if the …

Does The Fdcpa Apply In Bankruptcy?, Garam Choe

Bankruptcy Research Library

(Excerpt)

In 1977, Congress enacted the Fair Debt Collection Practices Act (“FDCPA”) to remedy rampant abusive debt collection practices by debt collectors. A year later, the Bankruptcy Code was enacted under Title 11 of the United States Code. Conflicts arise as to whether which law applies when debt collectors use abusive debt collection practices while seeking to recover from a debtor in a bankruptcy case. Circuit courts are split as to whether the Bankruptcy Code displaces the FDCPA in the bankruptcy context. Some circuit courts have concluded that the Bankruptcy Code displaces the FDCPA in the bankruptcy context. Alternatively, some …

Borrowers And Bankruptcy Trustees’ Unsuccessful Attempts To Avoid A Mortgage Under The “Splitting-The-Note” Theory, Alana Friedberg

Bankruptcy Research Library

(Excerpt)

In 1993, the mortgage industry created the electronic database Mortgage Electronic Registration System (“MERS”) in order to “track ownership interests in residential mortgages.” MERS “serves as the mortgagee in the land records for loans registered on the MERS System, and is a nominee (or agent) for the owner of the promissory note.” To date, MERS holds title to around 60 million home mortgages, about half of all home mortgages in the United States.

Borrowers and bankruptcy trustees have attempted unsuccessfully to argue a mortgage or deed of trust is void if a third party, such as MERS, was designated …
