Dft Investigation Of Lewis Acid Assisted C-Cn Bond Activation Of Benzonitrile With [Ni(Dmpe)] Fragment, Lubna Kader

Theses and Dissertations

There has been recent interest in the field of organometallics with C—C bond activation of organic substrates that are mediated by transition metal complexes. The bond activation of C—C bonds is important, not only in organic synthesis but also in industrial processes. However, the activation of these bonds remains difficult since they are thermodynamically more stable and sterically less available to activate than the activation of the C—H bond. Most of the successful C—C cleavage uses the relief of ring strain, achievement of aromaticity, or proximity, as the driving force for the reaction.3 Another strategy is the use of a …

Theses and Dissertations

Through pulse filamentation, femtosecond laser pulses have been utilized to modify the refractive indices of dielectric materials such as glass, A-plane sapphire crystal, and Cplane sapphire crystal. The 10x Infinity Corrected Lens was used, and the focusing condition was tuned as being the same and fixed to both glass and sapphire crystals. First, 8uJ of laser energy was optimized to produce controlled pulse filamentation voids in the glass. The laser intensity was then optimized to 2-3.5 uJ, 1.5 uJ, & 2.5 uJ, respectively, for the controlled pulse filamentation in A and C plane sapphire crystals. Due to the different crystal …

A Study Of The Constitutive Models Used In Analyzing Dynamic Strain Aging In Austenitic Stainless Steel 304, Mohammad Mohiuddin

Theses and Dissertations

When triggered, dynamic strain aging has a significant impact on the microstructural mechanical behavior of austenitic stainless steel 304 high performance alloy. The dynamic strain aging phenomenon has been shown to cause significant additional hardening in several experimental studies. To effectively predict the behavior of the material, it is required to employ a constitutive model that includes dynamic strain aging. The extra hardness brought on by dynamic strain aging is captured in this study by the proposal of a novel constitutive model (VAS model) for Austenitic Stainless Steel (ASS) 304 high performance alloy. As part of this study, the developed …

Numerical Simulation Of Vibration - Based Piezoelectric Energy Harvester For Shape Comparison, Adriana Rosas

Theses and Dissertations

This work investigates the shape optimization of piezoelectric energy harvesters subjected to mechanical vibration using ABAQUS/Standard software. Three piezoelectric energy harvesters with different dimensions but the same areas were created to identify if model dimensions have an impact on the output voltage. The models were tested at different speeds to create an output voltage. Once the output voltages were obtained, the results were compared with each other to find if shape optimization on piezoelectric energy harvesters has an impact on scavenging energy from mechanical vibrations.

Excessive engagement in video game play can lead to significant impairment and clinically significant levels of harm. However, there are several important gaps in the research literature which limit understanding of potential harm. First, little is known about the gaming behavior of students, ranging from middle-school to graduate school, specifically as it relates to their reasons for playing video games and their time spent playing. Second, concerns …

A Frayed Edge: A Qualitative And Poetic Inquiry Analysis Of White Antiracist Protest In 2020, Emily Katt

Electronic Theses and Dissertations

This multiphasic study explored the narratives of five first-time Black Lives Matter protesters demonstrating during the historic confluence of conflicts in 2020 America. After positioning the liminal 2020 circumstances within an antiracist research lens, the author analyzed, first through grounded theory and then secondarily through poetic inquiry, how these five participants described their protest experiences. The grounded theory phase yielded an overarching theory that first-time protestors experienced a dual process of unsuturing and of calling-out, with three subthemes categorized within each of these two processes. The author moved into analysis with the poetic inquiry phase, crafting poems guided by six …

Folic Acid – Carbon Dots – Doxorubicin Nanoparticles As Cancer Theranostic, Michael Tetteh

Electronic Theses and Dissertations

This work focused on engineering bi-functionalized nanoparticles (NPs) based on carbon dots (CDs) to improve early cancer detection and treatment. Therefore, using folic acid (FA) as a targeting agent, the CDs were prepared to deliver high concentrations (HC) of doxorubicin (DOX) and gemcitabine (GEM) covalently and non-covalently to cancer cells. The prepared FA-CDs-DOX/GEM-HC NPs were characterized using ultraviolet-visible spectroscopy, fluorescence spectroscopy, and Fourier transform infrared spectroscopy. Assessment of the drug loading capacity (DLC) and drug loading efficiency (DLE) indicated that the non-covalent NPs have low DLC but high DLE compared to the relatively low DLE and high DLC of covalent …

Carceral Intent, Danielle C. Jefferis

Michigan Journal of Race and Law

For decades, scholars across disciplines have examined the stark injustice of American carceralism. Among that body of work are analyses of the various intent requirements embedded in the constitutional doctrine that governs the state’s power to incarcerate. These intent requirements include the “deliberate indifference” standard of the Eighth Amendment, which regulates prison conditions, and the “punitive intent” standard of due process jurisprudence, which regulates the scope of confinement.

This Article coins the term “carceral intent” to refer collectively to those legal intent requirements and examines critically the role of carceral intent in shaping and maintaining the deep-rooted structural racism and …

Africana Legal Studies: A New Theoretical Approach To Law & Protocol, Angi Porter

Michigan Journal of Race and Law

“African people have produced the same general types of institutions for understanding and ordering their worlds as every other group of human beings. Though this should be obvious, the fact that we must go to great lengths to recognize and then demonstrate it speaks to the potent and invisible effect of the enslavement and colonization of African people over the last 500 years.” – Greg Carr

Shape Deformities In Recycled Concrete As A Substitute Aggregate In Concrete, Carson D. Timmerman

Construction Management

Concrete is a universal material that is used widely across the construction industry. Within a standard concrete mix, a fine aggregate and a coarse aggregate are added to the mix design to help with solidity and compressive strength in the mixture. The admixtures, additives, slump, and mix ratios will differ based on the compressive strength you're trying to attain. This paper directly reflects the results of the differences between shapes in recycled concrete used as a coarse aggregate substitute in concrete mixes. As the construction industry grows, so does outreach towards sustainability and reusing materials anywhere the industry can. Testing …

Navy Blues: Between Waves And Warriors, Reinetta A. Vaneendenburg

English Theses & Dissertations

Personal narrative, segments of oral histories, and short prose poetry combine to reflect the experience of contemporary women line officers in the U.S. Navy. I drew from my thirty-plus years of naval service as well as oral interviews that I have collected to depict this significant transitional period for women, whose roles expanded from clerks and fleet support administrators to trained warriors and watch standers, ready for the next mission. Themes such as personal identity, sexuality, and social pressures combine to form a portrait of adventuresome and talented young women who did, indeed, persist, and persevere.

Counselor Perceived Competence Diagnosing Disorders From Dsm-5 Diagnostic Categories Survey Results And The Development And Validation Of Scores On The Diagnostic Self-Efficacy Scale, Erin Elizabeth Woods

Counseling & Human Services Theses & Dissertations

This dissertation focused on the diagnostic self-efficacy of mental health counselors. The diagnosis of mental health disorders serves a wide array of functions in the counseling field including communication, treatment planning, and third-party reimbursement. Self-efficacy, or one’s belief in their own ability to accomplish a task, is considered a factor in successful task completion. The literature lacked information about which mental health disorders counselors are most confident diagnosing and an instrument which measured the self-efficacy of counselors specific to the diagnostic process. The MEASURE approach was employed to create the Diagnostic Self-Efficacy Scale and validate scores on this instrument with …

Centering Community College Students' Experiences: A Multiple Methods Study Of Multiple Measures For Writing Placement, Nicole L. Hancock

English Theses & Dissertations

Community colleges are trying to reform their placement procedures from use of a single placement test score to a system that collects multiple measures to be used either as a replacement solitary measure or in conjunction with other measures for more accurate placement into writing courses than what occurred with the placement test, which often resulted in disparate impact for students of color. In this study of multiple measures placement assessment for writing courses, I critique several large studies of community college multiple measures assessment for the lack of a community college perspective. The studies largely supported use of high …

Heat Waves And A Public-Private Partnership In Alaska, Karen Sandrik, Sarah Matsumoto

Alaska Law Review

The recently-passed Inflation Reduction Act represents the largest single step that Congress has taken to combat harms from climate change. In its over $360 billion commitment, the Act incentivizes clean energy development and generation, includes methods to directly lower residential utility bills and increase home efficiency, promotes cleaner transportation and agricultural practices, and funds states' and cities' efforts to meet their individual climate goals. While many environmental organizations applauded the Act's passage, some—even simultaneously—expressed concern about its tradeoffs: the Act continues to invest in fossil fuels, subsidizing pipeline construction and guaranteeing new oil and gas leases, specifically expanding leasing in …

Coastal Marine Debris In Alaska: Problems Withplastics, Pollution, & Policy, Savannah Artusi

Alaska Law Review

Plastics pollute people and the planet throughout their lifecycle, from intensive extraction of raw materials to chemical leaching during their use to entangling animals in discarded plastic products. Plastic waste is especially troublesome in Alaska, where the state's extensive shoreline and coastal communities are disproportionately inundated with plastic marine debris. Current policies internationally, in the United States, and in Alaska have not done enough to prevent plastic waste from ending up on Alaska's coasts, to hold plastic producers accountable for that waste, or to provide Alaskan communities the support needed to remove the waste themselves. This Note offers several proposals …

Capstone Projects and Master's Theses

Research shows that the mental health crisis among collegiate athletes' has become an increasingly alarming issue. However, there is little done regarding the advocation for athletes on college campuses across the nation. At the junior college level, this reigns to be true, as research conducted shows there to be little research available on this group. This paper introduces a workshop that emphasizes the awareness of mental wellness and coping strategies for junior college (JUCO) athletes. The main goal of this workshop was to create a conversation about mental wellness at the JUCO level, as a majority of research was done …

Voltage-Gated Potassium Channel Dependent Mechanisms Of Cardiovascular Adaptation To Chronic Exercise., Sean Raph

Electronic Theses and Dissertations

Exercise increases cardiac workload, escalating the demand for oxygen. The myocardial vasculature responds to the greater demand for oxygen by increasing blood flow to match the needs of the heart during augmented work. Increasing blood flow requires the coronary arteries dilate (a.k.a. vasodilation); this is mediated predominantly by vascular smooth muscle cell relaxation. Vasodilation is driven through inhibition of calcium influx into vascular smooth muscle cells. The prevention of calcium influx is largely mediated by efflux of potassium via potassium channels causing membrane hyperpolarization, which in turn closes voltage-dependent (or gated) calcium channels (VDCC). Changes in vascular smooth muscle cell …

The Graduate Record Examination And Graduate Admissions: Issues In Diversity, Lauren Rankin

Dissertations

Doctoral education is an expensive and difficult endeavor. Program faculty are interested in finding students who will be successful in completing their courses and obtaining employment. The Graduate Record Examination (GRE) is often used to assess a student’s readiness for the rigors of graduate education. A student’s readiness for doctoral education can be assessed through analyzing the predictive validity of the GRE with various outcomes such as grade point average, scholarly output, and time to completion. However, this measure may not predict success for all students with potential bias towards students who are international and linguistically diverse. A total of …

Law enforcement officers in this sample were grouped into three clusters based on the number of years of patrol experience (10 years or less versus more than 10 years), the education level (less than a bachelor’s degree versus at least a bachelor’s degree), and training (advanced training versus basic training). The key findings were A) The three clusters of law enforcement officers were well distinguished. The first cluster …

Mathematical Knowledge For Teaching As Decision-Making For The University Mathematician Developing Coherence In Review Of Discrete Mathematics, Julie Lang

Dissertations

Mathematicians teaching at the university level have a deep understanding and appreciation for the mathematics that they teach. However, they rarely receive much formal training in teaching. Thus, university mathematicians must rely on their mathematical understandings and personally developed ideas of teaching to guide their decision-making. Relatively little research exists on mathematicians’ teaching practices. The purpose of this study was to examine the mathematical knowledge for teaching (MKT) of a university mathematician teaching discrete mathematics and how he leveraged his knowledge to make decisions and develop coherence among mathematical ideas during a semester review. An enactivist perspective examining a mathematician’s …

Political Astuteness Of Nurse Educators, Gail Marie Hanson Brenner

Dissertations

Nurses comprise the largest segment of the healthcare workforce. Although nurses have advocated for patients since Florence Nightingale’s time, advocating for changes in health policies that affect populations on a larger scale has not changed over time (Rasheed et al., 2020). Professional nursing associations, nurse educators, and the Institute of Medicine have all identified the need to educate nurses in advocacy and health policy. With the recent revision of the American Association of Colleges of Nursing’s Essentials publication, health policy has moved from an essential to a featured concept that is found in the competencies and subcompetencies of the domains. …

Due to their computational capabilities in big data, many researchers have been attempting to incorporate machine-learning in prediction and inference problems. One of the recent methods that got a lot of attentions was referred to as the double machine learning method (DML). This method attempts to estimate the effect of the treatment variable in the presence of high-dimensional nuisance function by incorporating machine-learning algorithms. Previous studies have shown that the DML method is able to …

Estimating The Distribution Of Ratio Of Paired Event Times In Phase Ii Oncology Trials, Li Chen, Mark Burkard, Jianrong Wu, Jill M. Kolesar, Chi Wang

Markey Cancer Center Faculty Publications

With the rapid development of new anti-cancer agents which are cytostatic, new endpoints are needed to better measure treatment efficacy in phase II trials. For this purpose, Von Hoff (1998) proposed the growth modulation index (GMI), that is, the ratio between times to progression or progression-free survival times in two successive treatment lines. An essential task in studies using GMI as an endpoint is to estimate the distribution of GMI. Traditional methods for survival data have been used for estimating the GMI distribution because censoring is common for GMI data. However, we point out that the independent censoring assumption required …

The Effect Of Numeracy And Math Anxiety On Whole Number Bias, Jasmine Jessica Leanna Bonsel

Electronic Theses, Projects, and Dissertations

Whole number bias (WNB) has been defined as the tendency to apply natural number knowledge to rational numbers. This misapplication can often lead to erroneous responses in mathematical tasks and understanding of rational number properties. Whole number bias can be explored using Dual Processing Theories. According to Dual Processing Theory we have two types of thinking: Type I and Type II. Type I is fast, heuristic based, intuitive, and doesn’t require working memory, while Type II is slow, logic based, analytical, and requires working memory. Some researchers argue that WNB is an intuitive phenomenon and occurs from a failure to …
