Reservoir Scale Implication Of Microbial Coal-To-Methane Conversion, Rohit Pandey

Dissertations

Increased world-wide interest in reducing the carbon-footprint of human activities has driven the coal-fueled energy industry to transition to a natural gas fueled future. Coupled with the continually increasing energy demand, the interest in alternate sources of natural gas has gained momentum. Microbially enhanced coalbed methane (MECBM), which aims at microbially converting in situ coal to methane provides one such alternate source of natural gas. Feasibility of MECBM as a viable technology is two-pronged, focusing on associated microbiology, and flow-governing reservoir response. The general advance of research in this area has thus far been from a microbial perspective, where coal-to-methane …

Dissertations

A literature review was conducted to examine the concept of self-care as a proactive means to manage the stressors of life, enhance professional competency, and live a well-balanced lifestyle, particularly for graduate-level psychology students. Different levels of distress, including stress, compassion fatigue, and burnout, were researched and discussed. The various domains of self-care were discussed as were the benefits of engaging in regular self-care practices. Finally, various ways to incorporate self-care into already established graduate-level training programs at universities and practicum training sites were discussed to enhance the training experience as well as mitigate burnout in the novel clinician.

Antibiotic Resistant Bacteria, Antibiotic Resistance Genes And Potential Drivers In The Aquatic Environments, Shuo Shen

Dissertations

As antibiotic resistance genes in aquatic environment have been increasing across the world, affecting water quality and public health, many studies documented concentrations of antibiotic resistance genes and some studies discussed their potential drivers. However, systematic and quantitative reviews that link antibiotic resistance genes (ARGs) to anthropogenic and environmental factors are limited. Nevertheless, this information will be important for developing regulation policy on controlling antibiotic use and therefore reducing potential risks to antibiotic resistance. I conducted meta-analysis of ARGs concentration at a global scale using Bayesian inference to explore climatic and socio-economic factors as drivers. I found local-scale climatic variables …

River otters are semi-aquatic social predators that can be found throughout North America. This is the first study to examine the vocalizations of wild river otters, and results are compared across field sites in the different regions. River otter vocalizations and behaviors in New York were recorded using Bushnell Aggressor trail cameras that …

Agonistic Grooming In Multiple Lemur Species, Jennie L. Christopher

Dissertations

Social behaviors are represented in every animal species regardless of the level of sociability found in the species. At the very least, conspecifics must interact for the continuation of the species. Depending on species, social behavior could merely consist of mating and territorial disputes, it could consist of a multitude of social behaviors that provide a way of navigating a complex societal structure, or it could consist of any level of interaction between those extremes. However, the behaviors that make up these social repertoires are not universal across species. They could differ in either the form or function of the …

Social And Individual-Level Identities And College Male Alcohol Use Behaviors: Examining The Utility Of Protective Behavioral Strategies, Robert Bearden Whitley

Dissertations

Recent literature has consistently identified conformity to traditional masculine norms as motivating hazardous drinking behaviors of college men. Given the high prevalence of hazardous drinking among college men and the particular negative consequences that emerge secondary to it, additional research is needed in this area to better identify possible intervention targets. The present study sought to better elucidate the proximity of male norm conformity to drinking behaviors through including a specific identity factor related to alcohol use: drinking identity. Secondary to this goal, this study also sought to examine how these factors of identity predicted the safe drinking behaviors of …

An Investigation Of The Impacts Of Traditional, Virtual, And Hybrid Biological Laboratories On College Students’ Achievement And Motivation To Learn Biology, Shavonda Jackson

Dissertations

Virtual courses function in a different manner than traditional courses, therefore they require teaching methods and assessment techniques geared specifically to maximize this learning experience. Internet-based learning and distance-education are no longer new concepts in the science field. Because of this, many collegiate biology programs have created courses that can be taken virtual or hybrid. A number of experimental studies have had great influence in terms of the effects and impacts of educational technology in relation to virtual laboratories.

However, not many studies emphasize the impact of hybrid laboratories on student achievement or assess students’ motivation to learn in a …

Agency And Parallelism In Three Saxophone Works By Dorothy Chang: A Performative Analysis, Courtney Elizabeth Long

Dissertations

Dorothy Chang’s saxophone works are significant contributions to modern saxophone repertoire. Chang’s music employs multifaceted construction that presents unique post-tonal vocabularies with significant motivic action within traditional frameworks, which creates a dialogue with the past and present. This provides a wealth of interpretive avenues for performers. Nonetheless, there is a lack of scholarship pertaining to Chang and her works. This dissertation’s analytical focus of Two Preludes for alto saxophone and piano (1993), Walk on Water for alto saxophone and cello (2004), and Afterlight for soprano saxophone and piano (2018) initiates the necessary conversation of Chang’s importance as a composer while …

Caring About More Than Grades And Test Scores: The Work Of Reputationally Caring Teachers, Gregory Max Chalfin

Dissertations

Using Nel Noddings’ definition of care as a theoretical framework (2005) alongside Elliot Eisner’s ecology of schooling (1988), this study examined how “reputationally caring” teachers approached assessment in their classrooms and their reasons for doing so. These topics were explored through interviewing and observing participants, in addition to analyzing documents related to their methods of assessment, utilizing the research methodology of educational criticism and connoisseurship. This qualitative study include four “reputationally caring” teachers. The term “reputational care” is of the author’s creation and refers to those teachers who are known by various school constituents: parents, students, colleagues, and administrators as …

Comparative Host Response And Gene Regulation In Deer Mice And Syrian Golden Hamsters During Acute Infection With Modoc Virus, Tyler Sherman

Dissertations

Flaviviruses (family Flaviviridae, genus Flavivirus) comprise a diverse group of globally-distributed viruses that may specifically infect vertebrates, invertebrates, or both. Of those that can replicate in both invertebrates (such as ticks and mosquitoes) as well as vertebrates (such as mammals), many represent important human pathogens. Examples of these include dengue virus (DENV), which may cause severe hemorrhagic fevers, West Nile virus (WNV), Japanese encephalitis virus (JEV), and Zika virus (ZIKV), all of which may cause febrile illness with neurologic involvement, and yellow fever virus (YFV), which may induce hepatic dysfunction.

Coaching College Students To Thrive: Exploring Coaching Practices In Higher Education, Alicia Sepulveda

Dissertations

The purpose of this study was to explore how trained, four-year success coaches perceive their coaching practice with students in higher education, particularly in the context of their meetings. While coaching programs have proliferated, little is known about coaching as a practice in higher education and it is difficult to generalize findings because professionals are ‘coaching’ in different ways. Some academic coaches in the field have stated they were given a title, but they are not ‘coaching’ (Sepulveda, 2017). Little is known about coaching as a practice, and this study will help to fill this gap. Taking a narrative approach, …

Establishment Of Organoids From Gastric Stem Cells And Their Use To Study The Role Of Aryl-Hydrocarbon Receptors, Shakila Afroz Taleb

Dissertations

Stem cells are powerful tools in different aspects of biomedical and translational research, including disease modelling, drug testing, and tissue engineering for regenerative medicine. However, isolation and culture of organ-specific stem cells are challenging tasks. Therefore, the biological features of many adult stem cells are not well studied and their involvement in the development of cancer is still controversial. Some immortal stem cell lines have been established and used as an alternative to studying features of organ-specific stem cells. The ability to grow cells in a scaffold-free, three-dimensional (3D) model system that mimics in vivo conditions would help in revealing …

Investigating Drivers Of Genetic Structure In Plants: Global, Regional And Local Scales, Diana Gamba-Moreno

Dissertations

Genetic structure within and among plant populations is a critical component of plant biodiversity, informing local adaptation, conservation, and incipient speciation. However, its drivers remain poorly understood, especially across different spatial scales. In my dissertation I examined factors that affect plant population genetic structure at global, regional, and local scales. At the global scale, I performed a literature review of population genetic differentiation (F_ST) in seed plants based on a 337-species dataset with data on F_ST and species traits. Using phylogenetic multiple regressions, I found that F_ST is higher for tropical, mixed-mating, non-woody species pollinated by …

Sedative And Neurotoxic Properties Of Brexanolone Compared To Midazolam In The Developing Rodent Brain, Jacob Huffman

Dissertations

The developing brain is susceptible to extensive neurotoxicity following exposure to sedative/anesthetic drugs (SADs). Every year hundreds of thousands of children around the world are exposed to SADs with no viable non-neurotoxic agents approved for clinical use. Allopregnanolone (AlloP) has well-established sedative effects in adults and neonates. AlloP and many SADs produce sedation/anesthesia through allosteric modulation of GABA_A receptors, which is one of two principal mechanisms behind SAD-induced neurotoxicity. Evidence suggests AlloP has the unique capacity to regulate key apoptotic factors in adults and is widely involved with critical stages of neurodevelopment, indicating this neurosteroid might serve as a …

Awareness Of Increased Risk For Heart Disease And Cardiovascular Risk Factors In Women With Systemic Lupus Erythematosus, Patricia Catherine Weinstein

Dissertations

Women with systemic lupus erythematosus (SLE) develop cardiovascular disease (CVD) earlier and at a more accelerated rate compared to women without SLE. Many women with SLE are unaware of their increased risk despite years spent in the health care system, thus giving the atherogenic process time to accrue damage. Research has not explained fully why women with SLE are unaware of their increased risk for CVD or why awareness does not correspond to risk reducing behaviors. Stage theories of behavior like the Precaution Adoption Process Model (PAPM) propose that health behavior change proceeds through qualitatively different stages, and people at …

An Evaluation Of The Molecular Species Of Ca125 Across The Three Phases Of The Menstrual Cycle, Monica Rose Mclemore

Dissertations

CA125, a tumor-associated antigen, is primarily used to monitor epithelial ovarian cancer. However, CA125 alone lacks the sensitivity and specificity necessary for population-based screening in healthy women. Barriers to the development of a screening assay includes the low incidence of the disease, large inter-individual variability in CA125 levels, fluctuations in levels during the phases of the menstrual cycle (i.e., menses, follicular, luteal), ethnicity, menopausal status, and other benign conditions. Evaluation of the molecular species of serum CA125 is a vital step in understanding the underlying biology of CA125. The specific aims of this study, in a sample of healthy women …

Buccal Pulse Oximetry: Accuracy And Precision, Patricia N. Meza

Dissertations

Clinicians assess multiple biomarkers and patient signs/symptoms in clinical settings such as intensive care units, operating rooms, emergency departments, and patient transport. Pulse oximetry monitoring remains a standard. There are instances in which traditional pulse oximetry monitoring sites, such as the fingers, toes or earlobes, fail or access is infeasible. In these instances, clinicians seek alternative monitoring sites, such as the buccal area. Unstable patients may also challenge ability to acquire a pulse oximetry signal, possibly preventing reliable pulse oximetry values. Compared to fingers or toes, the buccal area is not as susceptible to local vasoconstriction effects. Therefore, the buccal …
