An Examination Of Medical Resident Practices Regarding Patient Communication About Infant Safe Sleep Practices, Summer Samir Chahin

Dissertations

Infant mortality is a significant public health concern in the United States, particularly because of the large racial disparities in death rates. In particular, Black infants die at a rate twice that of white infants (Center for Disease Control, 2016). Sleep-related deaths are one of the most preventable causes of infant mortality. In Kalamazoo, Black and multi-racial infants account for the majority (3 out of 4) of sleep-related deaths (Sleep-Related Infant Deaths in Kalamazoo County Fact Sheet, 2017). To reduce sleep-related deaths, the American Academy of Pediatrics published recommendations for safe sleep practices (American Academy of Pediatrics, 2016).

Unfortunately, caregivers …

Vertex Identification In Graphs, Yuya Kono

Dissertations

In recent decades, there has been increased interest in studying ways touniquely identify the vertices of a given graph. Two of best-known vertex identification methods are referred to as the metric dimension introduced by Slater and by Harary, and Melter in the1970s, and the partition dimension introduced by Chartrand in 2000. The first method deals with locating an ordered set of vertices in a connected graph G and uniquely identifying each vertex of G by means of the distance between this vertex and the vertices in the ordered set. The second method deals with partitioning the vertex set of a …

Characterization Of Disorder And Its Effects On Two-Dimensional Transition Metal Dichalcogenides, Krystal Rose York

Dissertations

Since the discovery of the unique electrical properties of graphene in 2004, there has been an increased interest in two-dimensional (2D) materials.

So, there is a need for algorithms or models that can …

Cost-Effective Enablement Of Automated Driving Systems On Snow-Covered Roads, Nicholas Alan Goberville

Dissertations

The top reason for implementing automated driving features is to increase safety. Current deployed features like lane-keeping assist and adaptive cruise control have the ability to reduce collisions by up to 50%. However, due to perception limitations, these systems are only capable of operating in strict operational design domains. For example, the occlusion of lane lines introduced during winter weather conditions causes these safety systems to disengage. Companies targeting higher automated systems often use more expensive, high-fidelity sensors that may solve problems like this, but because of the high cost and minimal business model, deployments of such scope are unsustainable. …

Determining The Role Of Gata3 In A Sub-Population Of Vestibular Hair Cells, Sydney Sheltz-Kempf

Dissertations

The inner ear can be divided based on two functions: hearing and balance. The hearing organ is called the cochlea, while the organs responsible for balance are called the vestibular system. One of these vestibular organs, the utricle, is positioned horizontally in the body and relatively parallel to the ground, resulting in sensitive detection of both sideways, and forward and backward acceleration. One major question in the field of otolaryngology focuses on the unique differences between these organs and the evolutionary importance of their similarities. One particular gene of interest called Gata3 is initially expressed highly in the cochlea and …

Forming Connections: The Cell-Autonomous Roles Of Gata3 And Neurod1 In Developing Auditory Neurons, Elizabeth Madison Ketchum

Dissertations

Hearing loss is the most prevalent sensory disorder, yet current treatment options are restricted to hearing aids and cochlear implants. Both treatment options require the presence and proper formation of inner ear auditory afferent neurons, known as spiral ganglion neurons (SGNs). In many patients with hearing loss, these neurons are either not present or are improperly organized, making current therapeutic options nonviable. Although it would be ideal to preserve functioning SGNs or to regenerate them, we are still learning how SGNs develop and form their projections to their peripheral and central targets. Therefore, a better understanding of the genes involved …

Investigating The Role Of Fun30, A Chromatin Remodeler, In Dna Repair, Mehwish Iqbal

Dissertations

The repair of DNA double-strand breaks (DSBs) is crucial for maintaining genome stability. DSB repair needs to take place within the complex organization of the chromatin, and this requires changes in the chromatin structure adjacent to DSB sites. These changes occur through covalent histone modifications that alter histone-DNA contacts as well as by the action of ATP-dependent chromatin remodelers. Many chromatin remodelers, including Fun30, are involved in DSB repair. Fun30 facilitates DNA end resection at DSB site during the homologous recombination repair pathway. Apart from its role in DNA repair, Fun30 promotes gene silencing at heterochromatic loci such as telomeres, …

Delineating The Exocytic Fusion Machinery Required For Mast Cell Exocytosis, Pratikshya Adhikari

Dissertations

Mast cells undergo exocytosis to release a wide array of inflammatory mediators by utilizing membrane fusion proteins-SNAREs (soluble-N-ethyl-maleimide sensitive factor attachment protein receptor) along with essential regulatory Munc18 and Munc13 proteins. Accumulating evidence in mast cell biology suggests the existence of distinct pools of mast cell mediators. However, the precise mechanism underlying the release of each mast cell mediator is not clear. To determine whether different exocytic machineries are required for differential mediator release, I used reconstitution to investigate the differential role of Munc18s in fusion machinery regulation. Munc18a and Munc18c stimulated VAMP2 and VAMP3-mediated lipid mixing, whereas Munc18b only …

How Intensive Care Unit Nurses Conceive Of Personal And Professional Risk When Exercising Clinical Autonomy, William Albert Randall

Dissertations

Nurses are often encouraged to work to their fullest potential, including exercising clinical autonomy--a factor known to decrease morbidity and mortality. Nonetheless, nurses endure historical, societal, and professional barriers to be respected and independent. In the intensive care unit (ICU), critically ill, often unstable patients require nurses to respond quickly and adapt to each unique situation, which may mean migrating outside of formal rules, norms, and policies, or "rule-bending." However, as inherent subordinates of hospital administrators and physicians, rule-bending, no matter how well-intended, necessary, or benign, often cause nurses to function in a grey zone of vulnerability and risk.

I …
