Sleep Disturbances And Depression: The Role Of Genes And Trauma, Mackenzie J. Lind

Theses and Dissertations

Sleep disturbances and insomnia are prevalent, with around 33% of adults indicating that they experience at least one main symptom of insomnia, and bidirectional relationships exist with common psychopathology, particularly major depressive disorder (MDD). However, genetic and environmental (e.g., traumatic event exposure) contributions to the etiology of these phenotypes are not yet well understood. A genetically informative sample of approximately 12,000 Han Chinese women aged 30-60 (50% with recurrent MDD) was used to address several gaps within the sleep literature. Sleep disturbances were assessed in all individuals using a general item addressing sleeplessness (GS). A sleep within depression sum score …

Protective Factors In The Association Between Child Sexual Abuse And Telomere Length In Adults, David Sosnowski

Theses and Dissertations

The purpose of the present study was to examine if childhood sexual abuse (CSA) was associated with decreases in mean telomere length (TL), and if social support and/or optimism moderated this association. The study included 99 Caucasian female monozygotic twins, ranging in age from 19-48 (M_age = 30.5, SD = 7.8) at Time 1. Linear mixed effects models were employed to test study hypotheses. Analyses with all participants did not detect an effect of CSA exposure or severity on mean TL, nor were there effects with optimism. However, in analyses that only included women exposed to abuse, increases …

Sol-Gel Chemistry: An Advanced Technique To Produce Macroscopic Nanostructures Of Metal And Semiconductor Colloids, Lamia Nahar

Theses and Dissertations

The fascinating physical properties that arise in materials limited to dimensions of 1-100 nm have gained noteworthy interest from the scientific community. Accordingly, there has been a lot of attention paid to the synthesis of discrete nanoparticles (NPs) and they are being investigated for a range of advanced technologies. Nonetheless, efficient use of nanomaterials in device applications require them to be assembled into solid state macro-structures while retaining their unique, nanoparticulate properties. To date, most commonly investigated assembling techniques include: covalent coupling of NPs surface groups, control evaporation of the solvent to produce ordered supercrystals or non-ordered glassy films, and …

Active Design: Creating A Blue Zones Model For Interior Environments, Alexis Holcombe

Theses and Dissertations

How might interior environments play a role in promoting life long well being? According to Passarino, et al., genetic variety only accounts for about 25% of the variation of human longevity. A combination of diet, environment and exercise comprise the greatest factors. The amount of time Americans spend indoors presents a challenge to increasing physical activity: the Environmental Protection Agency (EPA) states that Americans spend 93% of their lives indoors (Roberts, 2016). Therefore, if physical activity is crucial to living longer, the design of interior environments could logically be a critical factor in promoting natural movement and sustaining lifelong well-being. …

Synchrony And Concordance: A Multilevel Analysis Of The Effects Of Individual Differences During A Co2 Challenge, Rachel E. Wallace

Theses and Dissertations

Emotion theories posit that emotion systems (e.g., behavior, self-report, physiology) should be related when an emotion is being elicited because this serves an adaptive purpose and allows the individual to respond appropriately to the present situation. Oftentimes, this coherent relationship is not found, and research has hypothesized that the type of analyses used and lack of examination of individual differences could be affecting this relationship. Most studies examine the relationship between emotion systems between-subjects when within-subjects analyses may be more appropriate. The present study examined the relationship between self-reported distress (SUDS) and heart rate, and whether trait differences of anxiety …

Separate And Equal: Power Dynamics Between Women Sleeping With Women Partners, Helen Virginia Mays

Theses and Dissertations

The purpose of this study was to explore the power dynamics in relationships between women who sleep with women (WSW). Using private, semi-structured interviews, the areas of financial and sexual power were explored. A total of 10 participants were interviewed individually using a snowball sample. Previous literature has shown that WSW partners are egalitarian, meaning both partners share in the decision making, with respect to household chores and other decisions in the home (Blumstein & Shwartz, 1984; Kurdeck, 2006). Instead of WSW following gender scripts like some heterosexual partners, WSW couples decide roles by preference, choice and after discussing what …

A Range-Wide Assessment Of Migratory Connectivity For The Prothonotary Warbler Using Stable Hydrogen Isotopes, Jessica Reese

Theses and Dissertations

Populations of many species of migratory birds are declining, and an understanding of how populations are linked between the breeding and nonbreeding grounds is necessary in order to determine drivers of declines. While all current tracking technologies to study the movements of small songbirds are limited by their coarse resolution, tracking birds by measuring stable isotopes in keratin offers an advantage because it requires only a single capture and is cost-effective, which leads to robust sample sizes. While this tracking method is accurate, stable hydrogen isotope values measured in feathers (δ²H_f) are known to be variable …

Comparison Of Intraoral And Extraoral Scanners On The Accuracy Of Digital Model Articulation, Jason L. Porter

Theses and Dissertations

Introduction: Orthodontists increasingly rely on digital models in clinical practice. The ability of modern scanners to articulate digital models must be scientifically evaluated. Methods:Twenty five digital articulated models were produced from four digital scanners in five experimental groups. The resulting inter-arch measurements were compared to the gold standard. An acceptable range of 0.5mm more or less than the gold standard was used for evaluation. Results: iTero® and iTero® Element yielded all acceptable inter-arch measurements. The 3M™ True Definition and Ortho Insight 3D® with Regisil® bite registration produced four of six acceptable inter-arch measurements. The Ortho Insight 3D® with Coprwax ™ …

A Multi-Method Exploration Of The Genetic And Environmental Risks Contributing To Tobacco Use Behaviors In Young Adulthood, Elizabeth K. Do

Theses and Dissertations

Tobacco use remains the leading preventable cause of morbidity and mortality in both the United States and worldwide. Twin and family studies have demonstrated that both genetic and environmental factors are important contributors to tobacco use behaviors. Understanding how genes, the environment, and their interactions is critical to the development of public health interventions that focus on the reduction of tobacco related morbidity and mortality. However, few studies have examined the transition from adolescent to young adulthood – the time when many individuals are experimenting with and developing patterns of tobacco use. This dissertation thesis seeks to provide a comprehensive …

Chemical Probes For Protein Α-N-Terminal Methylation, Brianna D. Mackie

Theses and Dissertations

While protein α-N-terminal methylation has been known for nearly four decades since it was first uncovered on bacteria ribosomal proteins L33, the function of this modification is still not entirely understood. Recent discoveries have demonstrated α-N-terminal methylation is essential to stabilize the interactions between regulator of chromosome condensation 1 (RCC1) and chromatin during mitosis, to localize and enhance the interaction of centromere proteins (CENPs) with chromatin, and to facilitate the recruitment of DNA damage-binding protein 2 (DDB2) to DNA damage foci. Identification of N-terminal methyltransferase 1 (NTMT1) unveiled the eukaryotic methylation writer for protein α-N-termini. In addition, NTMT2 that shares …

Development Of My Footprint Calculator, Karthik Mummidisetti

Theses and Dissertations

The Environmental footprint is a very powerful tool that helps an individual to understand how their everyday activities are impacting environmental surroundings. Data shows that global climate change, which is a growing concern for nations all over the world, is already affecting humankind, plants and animals through raising ocean levels, droughts & desertification and changing weather patterns. In addition to a wide range of policy measures implemented by national and state governments, it is necessary for individuals to understand the impact that their lifestyle may have on their personal environmental footprint, and thus over the global climate change. “My Footprint …

In Search Of A Function For An Uncharacterized Conserved Protein In Streptococcus Sanguinis Sk36, Ayana Scott-Elliston

Theses and Dissertations

With the number of fully sequenced bacterial genomes increasing in the past 7 years, it has been discovered that a large percentage of the putative protein coding genes have no known function. This lack of knowledge leaves scientists with an incomplete understanding of bacteria. In this study, conserved hypothetical protein mutants from Streptococcus sanguinis SK36 were screened on solid media with various environmental conditions. From these screens, the candidate protein, SSA_2372, displayed a sensitivity to acidic conditions. Its homolog in Bacillus subtilis 168, BSU00030, also displayed a sensitivity to pH conditions at its acid tolerance extremes unlike its other homolog …

Effects Of Prescribed Fire On Cope’S Gray Treefrog (Hyla Chrysoscelis) Across Habitat Scales And Life Stages, Logan Mcdonald

Theses and Dissertations

Fire may alter both aquatic and terrestrial habitat used by all amphibian life stages, yet, our knowledge of its effects on amphibians is primarily limited to adult responses. I present an integrated approach to test the response of Cope’s Gray Treefrog (Hyla chrysoscelis) to fire by examining responses in tadpole performance and survivorship, adult abundance, and oviposition. Tadpoles raised with burned leaf litter had similar survival, but total mass and total length were 440% and 170% greater, respectively, for tadpoles raised in unburned litter. I assessed terrestrial and aquatic oviposition cues by embedding burned and unburned litter treatments within burned …

The Third Place: A Mixed-Use Building For Office Workers In The Central Business District, Mingming Zhao

Theses and Dissertations

Work-related stress is an issue of growing concern around the world.[1] The relationship between work stress and individuals’ psychological and physical health is well acknowledged.[2] In the survey of “stress in the workplace” conducted by American Psychological Association in 2012, two in five (41%) of employed adults report that they typically feel stressed during the workday, up from 36% in 2011, while less than six in ten (58%) report that they have the resources to manage work stress.[3] Historically, Central Business Districts are a focal point of cities, and are occupied by a large group of office buildings and a …

Comparisons Of Isogenic Trisomic And Disomic Cells From People With Mosaicism For Down Syndrome Unmask Cellular Differences Related To Trisomy 21, Kelly A. Rafferty

Theses and Dissertations

It is known that age-related changes impacting multiple organ systems occur earlier in people with Down syndrome (Ds), but the biological basis underlying this trisomy 21-associated propensity for premature aging is poorly understood. Given that the trisomic/normal cells from people with mosaic Ds (mDs) are identical with regards to environmental exposures and genes (except for chromosome 21 copy number), comparisons of these isogenic trisomic/disomic cells allow one to “unmask” the cellular consequences of trisomy 21 by removing extraneous factors. The primary aim of this study was to determine if trisomy 21 results in an increase in the acquisition of age-related …

Reliability And Stability Of The Six Question Disability Measure In The Current Population Survey: What The Data Can And Cannot Tell Us About Disability And Labor Force Participation, Jeffrey Joy Dr.

Theses and Dissertations

The Current Population Survey (CPS) has been a major source of disability data for public policy and research. The aim of this study was two-fold. First, the study examined the six disability measures added to the CPS in 2008 to determine if they are both a reliable and stable method of describing disability over a period of two survey administrations in a 12-month period. Second, this study then assessed the impact of disability upon labor force participation. This research used a subset of the respondents to the longitudinal CPS Annual Social and Economic Supplement; it included (N=11,721) respondents …

The Tuskegee Syphilis Experiment, Colleen Arthur

UROP Posters

The aim of this paper is to look into the human rights violations committed by the United States against the black men during the Tuskegee Syphilis Experiment as well as touch on the broader concept of racial medicine. In addition, my goal is to dismantle the pretense society may hold about the United States and the moral high ground it claims to stand on. In order to accomplish this goal, I will make parallels about atrocities committed by the United States on the African-American population to those committed by the Nazis on the Jewish population in Germany. I will first …

Can A Layer Of Antimicrobial Agents Be Placed Around Breast Implants To Prevent Staph Infections From Occurring?, Valerie L. Tran

UROP Posters

The most common infection that occurs after breast augmentation is a staph infection. Currently, there are only three ways to treat this type of infection, all of which treat the breast implant after the infection has developed. The first option is to treat the infection with an oral antibiotic. If this doesn’t completely rid the infection, then intravenous antibiotics are used. If this too doesn’t remove the infection, then surgery will be performed to remove the breast implant and a new implant will be inserted. Although, these options have a low mortality rate, the success rate of completely getting rid …

Aapt Diagnostic Criteria For Chronic Sickle Cell Disease Pain, Carlton Dampier, Tonya M. Palermo, Deepika S. Darbari, Kathryn Hassell, Wally Smith, William Zempsky

Neurology Publications

Pain in sickle cell disease (SCD) is associated with increased morbidity, mortality, and high health care costs. Although episodic acute pain is the hallmark of this disorder, there is an increasing awareness that chronic pain is part of the pain experience of many older adolescents and adults. A common set of criteria for classifying chronic pain associated with SCD would enhance SCD pain research efforts in epidemiology, pain mechanisms, and clinical trials of pain management interventions, and ultimately improve clinical assessment and management. As part of the collaborative effort between the Analgesic, Anesthetic, and Addiction Clinical Trial Translations Innovations Opportunities …

Doing Time And College: An Examination Of Carceral Influences On Experiences In Postsecondary Correctional Education, Lindsey Livingston Runell

Journal of Prison Education and Reentry (2014-2023)

Imprisonment pains often accompany confinement to correctional institutions and can be manifested through controlled interactions that are an ingrained part of these contexts. Less is known about how related discomforts and deprivations might specifically impact participation in postsecondary correctional education. This paper will shed light on possible ways that encounters between incarcerated college students, other prisoners, prison educators and corrections officers can influence their access to and quality of higher education received. It is based on qualitative data collected from interviews with 34 formerly incarcerated individuals who were past and present members of a higher education program post-release. This research …
