Bridging The In Between: A Portrait Of Asian American Student Affairs Professionals In Asian American Cultural Centers, Joliana Yee

Dissertations

Although the first Asian American Cultural Center (AACC) on a U.S. college campus came about as a result of student activism in the late 1960s and 33 other AACCs have since been established at higher education institutions across the country, very little has been documented in higher education scholarship about the Asian American Student Affairs Professionals (SAPros) who work within these unique institutional resources. While concerted efforts have been made to diversify the student body demographic at predominantly white institutions (PWIs), the negative impact of campus racial dynamics on students of color have nevertheless persisted and extant literature on the …

The Situational Context Of Safety Culture From The Perspective Of Medical-Surgical Staff Nurses And Nurse Leaders In A Hospital, Lisa Harton

Dissertations

People enter into healthcare facilities to maintain or restore health; however, often times those seeking health are harmed during the process by avoidable medical errors. Since the Institute of Medicine report on patient harm, safety culture continues to be the largest barrier in realizing safer patient care. Staff nurses' comprise the largest component of the health care workforce in hospitals and consistently have the lowest perceptions of a safety culture. Leaders who play a key role in creating and sustaining a safety culture consistently have the most favorable perception of safety culture. The development of a safety culture and safer …

Human Isocitrate Dehydrogenase Enzymes, Joseph Valentein Roman

Dissertations

Mammals have three forms of isocitrate dehydrogenase (ICDH) that each catalyze the oxidative decarboxylation of isocitrate forming alpha-ketoglutarate (AKG), carbon dioxide and reduced pyridine nucleotide. The intra-mitochondrial, citric acid cycle enzyme is ICDH III that exists as a hetero tetramer and uses NAD+ as a substrate. ICDH I and ICDH II are both dimeric enzymes that reside in the cytosol and use NADP+. While, the precise function of the cytosolic ICDHs is not known, active site variants of both ICDH I and II cause a variety of cancers. The R132H variant of ICDH1 is one of the most common alterations. …

Electron Transfer Of Shewanella Oneidensis Mr-1 At Clay-Modified Ito Electrode, Reem Faez Alshehri

Dissertations

Various strategies have been established to enhance the extracellular electron transfer and energy output capability of microbial fuel cells, with the majority being aimed at anode modification. The anode has a significant impact on the electricity generation performance of MFCs because it is in direct contact with the microorganisms. The materials of the anode should be favorable for the bacterial cell and capable to facilitate the electron transfer. Developing of an electrode using low-cost and effective materials assists to enhance the bacterial cell attachment and extracellular electron transfer. This provides a significant improvement in MFC performance. In this study, clay …

Making Moral Judgment More Responsive Via Constraints On Moral Beliefs, Principles, And Convictions, David Bukenhofer

Dissertations

A moral judgment is the conclusion of a psychological process, and a moral belief is thecognitive content resulting from it. Some experiences constrain the moral beliefs, principles, and convictions from which moral judgments are causally formed. If these experiences are associated with an underlying belief, principle, or conviction, they add context to it. Acquiring new contextual information through experience prompts reflection, which leads to the development of new morally relevant reasons. I hold that moral beliefs, principles, and convictions typically are involved in the formation of moral judgments, and that moral judgments typically are formed on the basis of moral …

Changing Concepts Of Merit In China's Education System: An Oral Historical Research Of Teachers In Key Schools, Yao Chen

Dissertations

This study examines teachers' views of meritocracy and how their conceptions and views influence their everyday practices in schools with regard to producing, recognizing, and awarding individual merit in China's key schools. This study uses a qualitative methodology, especially oral history interviews. It shows that the meaning of merit has changed over time, depending on cultural and institutional contexts during China's transition from Mao's age to the present. Thirteen teachers, who have been working in the education system of China since the early 1980s, and who have worked as teachers in China's key (magnet/elite) schools (including higher education institutions), were …

Cellular And Molecular Mechanism Underlying Alcohol Inhibition Of Bone Fracture Healing, Jonathan Michael Eby

Dissertations

Alcohol consumption is associated with increased risk taking and injuries leading to bone fracture. During bone fracture repair mesenchymal stem cells (MSCs) located at the site of injury differentiate into chondrocytes and osteoblasts to form a fracture callus. While most fractures heal without complication, studies show that alcohol abuse can lead to delayed fracture healing and fracture callus formation in both people and animals. Despite what is known about alcohol consumption in pre-injury pathologies like osteopenia and osteoporosis, the cellular and molecular mechanisms by which alcohol consumption inhibits fracture callus formation following orthopaedic injury remain to be elucidated. Here, we …

A Poetics Of Violence: Representations Of Violence As Storytelling And World-Building Tools Of The Theater, Richard Gilbert

Dissertations

This dissertation explores how representations of violence do dramaturgical work in theatrical production. Playwrights write scenes of violence, and directors and designers stage them, with specific dramaturgical goals in mind. The project of this work is to develop a theoretical framework for understanding how productions use representations of violence. Ideally, that framework will be of use both to critics seeking to analyze productions with violence and to practitioners who want to more consciously shape their own use of violence.

Representations of violence create a sudden change in the audience's affective experience of the fictional world. I call that sudden change …

Humanity In The Classroom: An Exploration Of Race In Teacher Behavior And Interaction With Students, Briellen Elizabeth Griffin

Dissertations

The hyper-surveillance of Black students has been well documented by educators and researchers across disciplines and reflects an increase in calls for research that examines the reproduction of racial inequality in educational spaces. To contend with the presence of antiblackness in the classroom is fundamentally about recognizing the humanity of Black students and interrogating the ways that they are dehumanized by racialized structures and social interactions. To examine antiblackness and humanity in the classroom, I conducted a critical collaborative case study with six teachers from an elementary school in a diverse Midwestern school district. I engaged BlackCrit Theory to examine …

Reducing Inequality And Poverty In Latin America: Conditional Cash Transfer Programs In Chile, Colombia, And Mexico, Jorge Humberto Guzman Gonzalez

Dissertations

Latin America is the most unequal region across the globe. Inequality has increased the election of populist leaders and has resulted in massive social movements and protests in the region. Nevertheless, at the beginning of the 2000s, a process of inequality reduction started in the majority of the countries. Since the end of the 1990s, a large number of Latin American countries were the world pioneers developing Conditional Cash Transfers (CCTs), to put money in the hands of the poor with the conditions of school attendance and nutritional check-ups for their children. Most of the studies have analyzed the effectiveness …

Estrogen Regulation Of Mir-9-5p And Mir-9-3p Stability And Localization In The Aging Female Brain, Chun Kim

Dissertations

In females, levels of estrogens fluctuate across the lifespan and rapidly decline during menopause. Hormone replacement therapy (HRT) has been introduced as a clinical alternative to replenish systemic levels of 17β-estradiol (E2), the primary estrogen in circulation. However, studies from the Women's Health Initiative revealed a critical period immediately following the onset of menopause where HRT is efficacious. Here, we identified the differential regulation of miRNAs, small non-coding RNAs that inhibit translation, as a potential mechanism for this temporal switch in estrogen action. Specifically, early - but not late - E2 administration following ovariectomy in a rat model of menopause …

Determining The Genetic And Phenotypic Profile Of Cord Blood Derived T Regulatory Cells And The Effect Of Calcitriol On Immune Suppression, Anya Nikolai-Yogerst

Dissertations

Recent outbreaks in vertically transmitted viruses, such as Zika virus and HIV, have rejuvenated interest in fetal and neonatal immune tolerance. Babies are susceptible to vertically transmitted viruses because fetal and neonatal immune systems are considered to be immune-privileged and will tolerate antigens presented to them by their mother. Thus, understanding the mechanisms of this tolerance is important to design effective treatments for infected mothers to protect their offspring. Here, I define a novel Treg, a type of T cell that mediates tolerance, named bidirectional T cells (BiT), found in human umbilical cord blood (UCB). These cells are induced by …

Factors Associated With Diabetic Peripheral Neuropathy And Quality Of Life Among Type 2 Diabetes Patients In Saudi Arabia, Awatef Ibraheem

Dissertations

Evidence has suggested that diabetic peripheral neuropathy (DPN) is associated with decreased quality of life (QoL) and impaired physical and emotional health. About 82% of the diabetic population in Saudi Arabia show signs of DPN. However, it is under-recognized and undertreated. Further, DPN is linked to several clinical and metabolic risk factors. However, there is minimal evidence from Saudi Arabia on the impact of DPN on the individual's QoL. The aims of this current study were to (1) examine the impact of DPN symptoms on functioning, health perception, and QoL and (2) explore the biologic and individual factors associated with …

Victims Of Child Sex Trafficking: Are U.S. Pediatricians Ready To Identify, Assess, Treat And Protect Them?, Bidisha Sinha

Dissertations

The trafficking of children for commercial sexual exploitation is a gross violation of human rights and a global, public health issue that is rapidly growing and prevalent. Due to the clandestine nature of this crime and the general lack of public knowledge about it, identifying and protecting victims of child sex trafficking (CST) is fraught with challenges. Therefore, it is imperative that healthcare professionals - often the only professionals with whom CST victims come in contact while in captivity - are properly educated and trained on this topic. A literature review reveals there is little knowledge about pediatricians' education and …

Modernism's Legacies: Forms, Feelings, And Figures, Shelby Sleevi

Dissertations

My dissertation, entitled "Modernism's Legacies: Forms, Feelings, and Figures," explores American modernism's legacies within contemporary fiction, not only as a set of aesthetic trends but also as a looming and influential mythos. Whether the practices and concerns of early twentieth-century literary modernism are evoked through obvious allusion, explicit reference, or strong resonance on the level of narrative, the contemporary texts in my discussion together attest to modernism's continued influence on and relevance for our current era. Tracing the legacies of William Faulkner, Gertrude Stein, Djuna Barnes, and Vladimir Nabokov in the contemporary fictions of Edward P. Jones, Julie Otsuka, George …

The Flexible Impact Of Affective States On Group Decision-Making And Ideational Creativity, Young-Jae Yoon

Dissertations

Positive and negative affect are often thought to influence the cognitive performance of individuals and groups via their effects on two different dimensions of cognitive processing style: heuristic vs. systematic processing, and global vs. local attentional focus. Recently, research has suggested that the effects of affective states on the analytic and creative performance of individuals depend on the relative dominance of heuristic vs. systematic processing (for analytic performance) and of a global vs. local attentional focus (for creative performance) just prior to the affect's arousal (Huntsinger, Isbell, & Clore, 2014; Huntsinger & Ray, 2016). Extending this individual-level evidence to small …

Patient-Specific Factors Associated With Surgical Delay In A Large Academic Hospital, Natalie Meyers

Dissertations

The high cost of healthcare is driving the search for more efficient practice, especially in high-stakes locations like the operating room. In addition to financial losses, patients suffer physical and emotional distress, including an increased risk of morbidity or mortality when surgical cases are delayed due to inefficiency. While patient-related causes of delay have been implicated, it is unclear which specific factors are most significant. This study aimed to identify specific patient factors correlated with surgical delay and develop a predictive risk algorithm that describes the relationship between patient-specific factors and surgical delay.

A retrospective review of 36,543 patients’ charts …

Brain Disease Detection From Eegs: Comparing Spiking And Recurrent Neural Networks For Non-Stationary Time Series Classification, Hristo Stoev

Modeling non-stationary time series data is a difficult problem area in AI, due to the fact that the statistical properties of the data change as the time series progresses. This complicates the classification of non-stationary time series, which is a method used in the detection of brain diseases from EEGs. Various techniques have been developed in the field of deep learning for tackling this problem, with recurrent neural networks (RNN) approaches utilising Long short-term memory (LSTM) architectures achieving a high degree of success. This study implements a new, spiking neural network-based approach to time series classification for the purpose of …

Content-Based Filtering Recommendation Approach To Label Irish Legal Judgements, Sandesh Gangadhar

Dissertations

Machine learning approaches are applied across several domains to either simplify or automate tasks which directly result in saved time or cost. Text document labelling is one such task that requires immense human knowledge about the domain and efforts to review, understand and label the documents. The company Stare Decisis summarises legal judgements and labels them as they are made available on Irish public legal source www.courts.ie. This research presents a recommendation-based approach to reduce the time for solicitors at Stare Decisis by reducing many numbers of available labels to pick from to a concentrated few that potentially contains the …

A Discrimination Aware Model To Predict Childhood Literacy Levels, Kate Byrne

Dissertations

It is illegal in Ireland to discriminate in the provision of education on the basis of multiple characteristics including gender, race and religion. While the increased use of machine learning models can open multiple avenues to identify early intervention strategies in education, caution must be exercised to ensure that any intervention does not discriminate with respect to a protected class. Poor literacy in childhood can have long term effects as the child ages, including on employment and mental health outcomes. Early intervention is key in mitigating this. In this dissertation, a model was created that predicted the outcome of a …

Enhanced Label Free Normal And Cancer Cells Classification Using Combined Parametric Modeling And Optical Techniques, Ayshathul Fouzia Abdul Gani

Dissertations

The development of label-free methods for cell classifications has been driven by the importance of early detection and identification of cancer disease. The future point-of-care (POC) treatment methods require rapid and real-time cancer screening techniques. As the labelled methods of cell classification are time-consuming processes and require a large amount of sample preparation along with skilled persons, they do not appear to be suitable for POC treatment methods. This necessitates the importance of such development. The label-free methods incorporate the biophysical properties of cells instead of biomarkers. The optical properties of cells have been frequently utilized for cell classification. This …

Convex Relaxations Of A Continuum Aggregation Model, And Their Efficient Numerical Solution, Mahdi Bandegi

Dissertations

In this dissertation, the global minimization of a large deviations rate function (the Helmholtz free energy functional) for the Boltzmann distribution is discussed. The Helmholtz functional arises in large systems of interacting particles — which are widely used as models in computational chemistry and molecular dynamics. Global minimizers of the rate function (Helmholtz functional) characterize the asymptotics of the partition function and thereby determine many important physical properties such as self-assembly, or phase transitions. Finding and verifying local minima to the Helmholtz free energy functional is relatively straightforward. However, finding and verifying global minima is much more difficult since the …

Quantitative Metrics For Mutation Testing, Amani M. Ayad

Dissertations

Program mutation is the process of generating versions of a base program by applying elementary syntactic modifications; this technique has been used in program testing in a variety of applications, most notably to assess the quality of a test data set. A good test set will discover the difference between the original program and mutant except if the mutant is semantically equivalent to the original program, despite being syntactically distinct.

Equivalent mutants are a major nuisance in the practice of mutation testing, because they introduce a significant amount of bias and uncertainty in the analysis of test results; indeed, mutants …

Dimension Reduction Techniques For High Dimensional And Ultra-High Dimensional Data, Subha Datta

Dissertations

This dissertation introduces two statistical techniques to tackle high-dimensional data, which is very commonplace nowadays. It consists of two topics which are inter-related by a common link, dimension reduction.

The first topic is a recently introduced classification technique, the weighted principal support vector machine (WPSVM), which is incorporated into a spatial point process framework. The WPSVM possesses an additional parameter, a weight parameter, besides the regularization parameter. Most statistical techniques, including WPSVM, have an inherent assumption of independence, which means the data points are not connected with each other in any manner. But spatial data violates this assumption. Correlation between …
