Receptor-Doped Organic Transistors: Transducing Anion Binding From Mixed Ionic-Electronic Transport, Anthony Benasco

Dissertations

Organic semiconductors based on π-conjugated polymers show remarkable properties such as high tolerance to structural defects, low processing temperature requirements, biocompatibility, ease of fabrication, and tunable properties. Conjugated polymers integrated into device arrays can exhibit collective properties sensitive to minor perturbations in the surrounding media. However, these devices rely on serendipitous sensitivity to the analyte of interest, and strategies for specific detection remain a considerable change. There remains a compelling, global need for technologies to monitor phosphate due to its prevalence in agricultural runoff, leading to fish kills and economic decline for commercial and recreational fisheries. The strong hydration energies …

Does Optic Flow Provide Information About Actions?, Hannah Masoner

Dissertations

Optic flow, the pattern of light generated in the visual field by motion of objects and the observer’s body, serves as information that underwrites perception of events, actions and affordances. This visual pattern informs the observer about their own actions in relation to their surroundings, as well as those of others. This study explored the limits of action detection for others as well as the role of optic flow. First-person videos were created using camera recordings of the actor’s perspective as they performed various movements (jumping jacks, jumping, squatting, sitting, etc.). In three experiments participants attempted to detect the action …

Interspecific Pollen Transfer, Gene Flow, And Speciation In Bat-Pollinated Burmeistera H. Karst. & Triana (Campanulaceae: Lobelioideae), Juan Moreira-Hernandez

Dissertations

The evolutionary success of angiosperms has been largely influenced by their interactions with animal pollinators, which provide pollen and gene transport between individuals, populations, and young diverging species. Here, I examine the interplay between interspecific pollen transfer (IPT) by shared pollinators, gene flow, and the evolution of reproductive isolation in the young rapid radiation of Neotropical bat-pollinated bellflowers in the genus Burmeistera (Campanulaeae: Lobelioideae). In Chapter 1, I conducted an extensive review of the pollination and plant speciation literature to highlight the evolutionary consequences of IPT in angiosperms and showed that it has profound consequences for the evolution of floral …

Roles Of Phospholipase Dε In Arabidopsis And Soybean Response To Nitrogen Deficiency, Shuaibing Yao

Dissertations

Phospholipase D (PLD) hydrolyzes phospholipids to produce phosphatidic acid (PA) and plays important roles in plant growth, development, and stress response. Of 12 PLDs in Arabidopsis, PLDε is involved in nitrogen response in Arabidopsis and canola, but the mechanism remained elusive. This study was undertaken to investigate how PLDε mediates plant response to nitrogen availability. Nitrogen deficiency induces an increase in PLDε transcript and protein levels and an increased association with intracellular membranes. PLDε interacts with autophagy-related protein 8e (ATG8e), and two of the four predicted ATG8-interacting motifs in PLDε are required for PLDε-ATG8e interactions. PLDε hydrolyzes phosphatidylethanolamine (PE) conjugated …

A Quantitative Study Of The Relationships Among Psychological Safety, Collaborative Capacity, And School Climate In Middle-Level Schools, Karen Brownfield

Dissertations

This quantitative study was conducted to investigate possible relationships between psychological safety, collaborative capacity, and school climate in middle level schools in order to identify specific leadership behaviors to increase collective efficacy. School leaders’ knowledge of the positive effect collective efficacy has on student learning is not enough (Donohoo & Katz, 2019; Parrett & Budge, 2020). Leaders must also be aware of functional behaviors to foster collective efficacy, thus increasing student learning (Donohoo & Katz, 2019). Based on the theoretical work of Bandura (2000, 2012), as well as DeWitt (2017), Garmston and Wellman (2013), Hattie (2017, 2019), and Rock (2013), …

The Effect Of Using The Adaptive Crawler™ On The Development Of Infants With Spina Bifida, Age 6-12 Months, Margaret E. Williams

Dissertations

During the timeframe of crawling, age 6--12 months, infants typically interact independently with their environment and their parents in order to perform certain developmental tasks. However, many infants with spina bifida are unable to crawl, as would typically developing infants. The inability to crawl may place these infants at a distinct disadvantage during this developmental timeframe. As a result of the developmental disadvantage, the parent-infant relationship may be negatively affected. For this study, the Adaptive Crawler™ assistive technology infant mobility device was designed, and a prototype created, to promote independent mobility and exploration of their environment by infants with spina …

Heart Rate Variability Following Treatment For Ptsd: Testing The Polyvagal Theory, Brittany F. Goodman

Dissertations

Posttraumatic stress disorder (PTSD) has been linked to lower heart rate variability (HRV), including measures of vagal tone. Treatments targeting the autonomic nervous system (ANS) have demonstrated efficacy in improving vagal tone, but it is less clear whether similar effects can also be achieved with cognitive therapies. The polyvagal theory has suggested that symptoms of social dysfunction are linked to vagal tone through a phylogenetically organized response to stress. HRV was collected during rest, reactivity (exposure to personalized trauma scripts), and recovery using a scripted imagery paradigm in female PTSD positive physical and sexual assault survivors (N = 41) …

Unsupervised Learning With Word Embeddings Captures Quiescent Knowledge From Covid-19 And Materials Science Literature, Tasnim H. Gharaibeh

Dissertations

Millions of scientific papers are produced each year and the scientific literature is continuing to grow at a head-spinning speed. Thus, massive scientific knowledge exists in solid text, but all these publications make it difficult, if not impossible, for researchers to keep in up to date with discoveries, even within a narrow scientific area. This massive amount of information also makes it difficult to find implicit and hidden connections, relationships, and dependencies within the information that may guide the direction of future research or lead to valuable new insights. So, there is a need for algorithms or models that can …

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 …

Delegitimizing Animal Rights And Environmental Activism: A Critical Discourse Analysis Of “Eco-Terrorism” In Congress And The Federal Courts, Joshua Varnell

Dissertations

Research on eco-terrorism has focused attention on many areas, from the analysis of the language used in specific pieces of legislation targeting animal rights and environmental activists, like the Animal Enterprise Protection Act, and the Animal Enterprise Terrorism Act, to the appropriateness of labeling individuals and groups eco-terrorist and/or terrorist given their non-violent stance and direct action campaigns which target property not people, and to law enforcement responses to those labeled eco-terrorist (Del Gandio and Nocella II 2014; Lovitz 2007; Carson, LaFree, and Dugan 2012; Loadenthal 2013b, 2014). The eco-terrorist discourse produces images of animal rights and environmental activists as …

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 …

Research Nurses' Attitudes And Practices Regarding Communication Of Risks And Benefits During The Research Informed Consent Process, Lidia Lika Nusbaum

Dissertations

Many studies show that research participants frequently do not fully comprehend information regarding risks and benefits (R&B) associated with clinical trials even though this is a fundamental component of the research informed consent (IC) process, required by ethical and regulatory guidelines. Research nurses often take an active role in obtaining IC while explaining study details and verifying potential participants' understanding. Although there are published recommended strategies to enhance the IC communication process, particularly for R&B communication, there is a paucity of research focused on research nurses' perspectives about the process. This study addresses this gap in the literature and provides …

Ocean Quahog (Arctica Islandica) Population Dynamics: Sex-Based Demographics And Regional Comparisons In The Northwest Atlantic, Kathleen M. Hemeon

Dissertations

Arctica islandica (ocean quahog) is the longest-lived bivalve on Earth. Individuals on the deep continental shelf of the Mid-Atlantic (US) can survive for centuries, and when found in the colder, boreal waters of Iceland, ages over 500 years can be reached. The ocean quahog is important in the US, yet very little is known about the resiliency of the ocean quahog stock to fishing activity, and ocean quahog recruitment patterns over time. To quantify and constrain age-reader error prior to age analysis, a triple-method error protocol was developed for A. islandica that included age-reader bias, precision, and error frequency. The …

Applications Of Simulation Analysis To Generate Reference Points And Evaluate Management Control Rules In Three Eastern Us Fisheries, Laura Solinger

Dissertations

Myriad sources of uncertainty are characteristic of or impact all commercial and recreational fisheries, contributing uncertainty to the determination of stock status. In the face of these uncertainties, fisheries managers tend to reserve fishery resources from the management targets to allow for variability. Simulation analysis is a useful tool to complement and extend formal stock assessment models to better inform managers of the risk that a management strategy results in an overfished stock or overfishing occurs over some period of time. Three examples of simulation analysis are presented to address risk-tolerance and development of management thresholds for three commercially important …
