Tunable Electronic And Optical Properties Of Low-Dimensional Materials, Shiyuan Gao Dec 2018

Tunable Electronic And Optical Properties Of Low-Dimensional Materials, Shiyuan Gao

Arts & Sciences Graduate Student Theses and Dissertations

Two-dimensional (2D) materials with single or a few atomic layers, such as graphene, hexagonal boron nitride (h-BN) and transition metal dichalcogenides (TMDCs), and the heterostructures or one-dimensional (1D) nanostructures they form, have attracted much attention recently as unique platforms for studying many condensed-matter phenomena and holds great potentials for nanoelectronics and optoelectronic applications. Apart from their unique intrinsic properties which has been intensively studied for over a decade by now, they also allow external control of many degrees of freedom, such as electrical gating, doping and layer stacking. In this thesis, I present a theoretical study of the electronic and …

Anodic Cyclization Reaction: Manipulation Of Reaction Pathway And Efforts To Radical Cation And Radical Intermediate, Ruozhu Feng Dec 2018

Anodic Cyclization Reaction: Manipulation Of Reaction Pathway And Efforts To Radical Cation And Radical Intermediate, Ruozhu Feng

Arts & Sciences Graduate Student Theses and Dissertations

In recent years, synthetic chemists have been expressing significant interest in electro-organic synthetic methods. This interest is being fueled by the existence of an increasing number of successful methods in the literature and the availability of new electrochemical equipment that removes the barrier to attempting an electrolysis reaction for the first time. Yet while these developments have fueled growth in some areas of electro-organic synthesis (the recycling of chemical catalysts for example), other areas remain underdeveloped. One such area is the exploration of reactions that can be triggered directly as an electrode surface without the use of any chemical reagent. …

Unsettling Geographies: Primitivist Utopias In Queer American Literature From Walt Whitman To Willa Cather, Benjamin Meiners Dec 2018

Unsettling Geographies: Primitivist Utopias In Queer American Literature From Walt Whitman To Willa Cather, Benjamin Meiners

Arts & Sciences Graduate Student Theses and Dissertations

In “Unsettling Geographies: Primitivist Utopias in Queer American Literature from Walt Whitman to Willa Cather,” I argue that the colonial discourse of primitivism played a central role in the queer literary imaginaries of both canonical and non-canonical U.S. authors. Building on the work of historians of sexuality who trace the complex development of the twentieth-century homo-/hetero- binary, I show how literary works produced in this historical moment—roughly 1860 to 1925—explored and in some instances even advocated alternative queer modes of citizenship and erotic imagination and practice. Focusing on the works of Walt Whitman, Emily Dickinson, Charles Warren Stoddard, and Willa …

Linking Structure And Dynamics In Metallic Liquids: A Combined Experimental And Molecular Dynamics Approach, Robert Ashcraft Dec 2018

Linking Structure And Dynamics In Metallic Liquids: A Combined Experimental And Molecular Dynamics Approach, Robert Ashcraft

Arts & Sciences Graduate Student Theses and Dissertations

A major outstanding problem in condensed matter physics is the nature of the glass transition, in which a rapidly cooled liquid can bypass the transition into a crystalline state and the liquid structure is "frozen-in" due to kinetic arrest. To characterize the fundamental features behind this transition the liquid, both in the high temperature (equilibrium) and supercooled state, needs to be better understood. By examining the relationship between structure and dynamics a better characterization of the liquid state and a determination of the mechanisms that are ultimately important for the formation of the glass can be gained. In this dissertation, …

The Effect Of Talker And Contextual Variability On Memory For Words In Sentences, Nichole Runge Dec 2018

The Effect Of Talker And Contextual Variability On Memory For Words In Sentences, Nichole Runge

Arts & Sciences Graduate Student Theses and Dissertations

Previous research has found that adding different forms of variability during study can affect later memory at test. For example, having words spoken by different talkers has been shown to improve recall of known and novel words (Goldinger et al., 1999; Barcroft & Sommers, 2005), and varying the cues in cue-target related word pairs has been found to improve recall of the targets (Glenberg, 1979; Bevan et al., 1966). It was unclear, however, whether benefits of variability would extend to more naturalistic stimuli, such as sentences, which have higher working memory demands. The present set of experiments investigated how talker …

Neural Mechanisms Of Drosophila Circadian Rhythms, Xitong Liang Dec 2018

Neural Mechanisms Of Drosophila Circadian Rhythms, Xitong Liang

Arts & Sciences Graduate Student Theses and Dissertations

Animals show circadian rhythms in a variety of physiological functions and behaviors. In Drosophila melanogaster, behavioral rhythms are driven by circadian clock genes that are oscillating in ~150 circadian pacemaker neurons. To explain how circadian neurons encode time and regulate different behavioral rhythms, I performed 24-hour in vivo whole-brain calcium imaging using light-sheet microscopy. First, I found that different groups of circadian neurons show circadian rhythms in spontaneous neural activity with diverse phases. The neural activity phases of the M and E pacemaker groups, which are associated with the morning and evening locomotor activities respectively, occur ~4 hours before their …

Singing As A Therapeutic Technique To Improve Gait For People With Parkinson Disease, Elinor Harrison Dec 2018

Singing As A Therapeutic Technique To Improve Gait For People With Parkinson Disease, Elinor Harrison

Arts & Sciences Graduate Student Theses and Dissertations

Abstract of the DissertationSinging as a Therapeutic Technique toImprove Gait for People with Parkinson DiseasebyElinor Clare HarrisonDoctor of Philosophy in Movement ScienceNeurosciencesWashington University in St. Louis, 2018Professor Gammon Earhart, ChairGait impairment is common in older adults and even more prevalent for people with Parkinson disease (PD). Gait dysfunction is often characterized by reductions in speed, step frequency, and step length. In addition, decreased ability to regulate step length and step frequency may contribute to increased gait variability, making walking less stable and increasing risk for falls. As gait deficits are often resistant to drug therapy, there is a need to …

Stability Of A Spinning Triangle Tethered Spacecraft System In A Circular Orbit, Matthew James Heitstuman Dec 2018

Stability Of A Spinning Triangle Tethered Spacecraft System In A Circular Orbit, Matthew James Heitstuman

Mechanical Engineering ETDs

Equations of motion are derived for a spinning triangle tethered spacecraft system and are used to analyze the stability of such systems. Floquet theory is applied to the linearized, periodic coefficient, equations of motion to analyze spin stability as a function of triangle geometry and the average spin rate of the satellite relative to the angular velocity of the spacecraft orbiting around a central body. The results of the Floquet analysis show that spin stability is achievable for many combinations of spacecraft geometry and spin rate. Spacecraft engineers or operators for a triangle-shaped tethered spacecraft can use this information for …

Chemically Modified Monolayer Surfaces Influence Valvular Interstitial Cell Attachment And Differentiation For Heart Valve Tissue Engineering, Matthew N. Rush Dec 2018

Chemically Modified Monolayer Surfaces Influence Valvular Interstitial Cell Attachment And Differentiation For Heart Valve Tissue Engineering, Matthew N. Rush

Nanoscience and Microsystems ETDs

As a cell mediated-process, valvular heart disease (VHD) results in significant morbidity and mortality world-wide. In the US alone, valvular heart disease VHD is estimated to affect 2.5% of the population with a disproportionate impact on an increasing elderly populous. It is well understood that the primary driver for valvular calcification is the differentiation of valvular interstitial cells (VICs) into an osteoblastic-like phenotype. However, the factors leading to the onset of osteoblastic-like VICs (obVICs) and resulting calcification are not fully understood and a more complete characterization of VIC differentiation and phenotypic change is required before treatment of valve disease or …

More Faculty of Science and Engineering Research

© 2018 Establishing agricultural activity using pollen analysis is one of the prime challenges of a palaeoecological investigation. Here we report combined pollen and archaeobotanical data originating from a waterlogged off-site organic-rich fill radiocarbon dated to ∼8 ka Cal BP located between the two occupation mounds at Neolithic-Chalcolithic Çatalhöyük, south central Turkey in order to investigate the record of Early Chalcolithic agricultural activity. Pollen results indicate extremely high abundances of Cerealia-type pollen (30->70%) and critical measurements of these show them to be Triticum-type, Avena/Triticum-type, Secale-type and Hordeum-type. Pollen data are also compared with archaeobotanical data retrieved from the same …

Adopting The Unadoptable/Disabled Subject In The Posthuman Era, Fu-Jen Chen Dec 2018

Adopting The Unadoptable/Disabled Subject In The Posthuman Era, Fu-Jen Chen

CLCWeb: Comparative Literature and Culture

In his article “Adopting the Unadoptable/Disabled Subject in the Posthuman Era,” Fu-Jen Chen first examines three memoirs that demonstrate prevalent features of today’s narratives by parents with adopted children of special needs and next offers a theoretical and ontological investigation of disability. He suggests that we have to change the way we relate to disability: to recognize it not as an external limitation but an internal as well as pre-existent division and to re-orient ourselves to the ontological truth that we are always already “disabled/otherized” especially in the posthuman era when the body is seen to exceed existing boundaries of …

The Rise Of The Neoliberal Chinese Female Subject In Go Lala Go, Su-Lin Yu Dec 2018

The Rise Of The Neoliberal Chinese Female Subject In Go Lala Go, Su-Lin Yu

CLCWeb: Comparative Literature and Culture

Built upon feminist critique of neoliberalism, this paper will examine a prominent medium through which neoliberal feminist ideology is disseminated: Go Lala Go. By analyzing the film, I will show how it co-opts the discourse of neoliberalism, and reworks it to construct neoliberal female subjects. First, I will explore what kind of role neoliberalism has enacted in the formation of an emergent type of female subject in China. Then, I will demonstrate how the contentious process of neoliberal feminism affects young career women’s identities. More than career guides promoting different techniques for making women more successful at their workplaces, …

Innovation, Entrepreneurship, And The Spirit Of Digital Capitalism, Collin Chua Dec 2018

Innovation, Entrepreneurship, And The Spirit Of Digital Capitalism, Collin Chua

CLCWeb: Comparative Literature and Culture

In his article “Innovation, Entrepreneurship, and the Spirit of Digital Capitalism,”Collin Chua analyzes the myth of innovation and the fantasy of entrepreneurship. The article draws on foundational perspectives regarding the spirit of capitalism established by Max Weber, later extended by Luc Boltanski and Eve Chiapello. The myth of innovation is interrogated, as innovation now operates as a rhetorical and managerial strategy that must be pursued in order to be competitive in today’s capitalist system. The fantasy of entrepreneurship is explored, as it serves as a coping mechanism for the fragmentation and erosion of traditional work arrangements and structures. The article …

Comparing Beijing's And Tokyo's Population Growths, Ernest M. Oleksy Dec 2018

Comparing Beijing's And Tokyo's Population Growths, Ernest M. Oleksy

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

The growth of the human population has led to the formation of largely populated agglomerations known as megacities. Although megacities can be found on multiple continents, Asia’s collection displays how megacities can develop in their own directions. Japan’s megacity of Tokyo, like other Japanese megacities, has adopted a western approach. China’s Beijing, on the other hand, continues to embrace its eastern roots. These megacities may differ in their ideologies, but they share in experiencing similar phenomena. One of these phenomena is population growth.

An Examination Of The Death Penalty, Alexandra N. Kremer Dec 2018

An Examination Of The Death Penalty, Alexandra N. Kremer

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

The death penalty, or capital punishment, is the use of execution through hanging, beheading, drowning, gas chambers, lethal injection, and electrocution among others in response to a crime. This has spurred much debate on whether it should be used for reasons such as ethics, revenge, economics, effectiveness as a deterrent, and constitutionality. Capital punishment has roots that date back to the 18th century B.C., but, as of 2016, has been abolished in law or practice by more than two thirds of the world’s countries and several states within the United States. Here, the arguments for and against the death …

Documents And Moral Knowledge: Art In Yellowstone National Park, Tim Gorichanaz Dec 2018

Documents And Moral Knowledge: Art In Yellowstone National Park, Tim Gorichanaz

Proceedings from the Document Academy

Documents have traditionally been conceptualized as representations of reality. Recently, scholars have been exploring how documents can also construct reality. In this paper, I follow this thread, discussing how documents can supply moral knowledge, showing what people ought to value in the world, thereby guiding action. Specifically, I discuss two works of art depicting Yellowstone National Park: a painting by Thomas Moran, done in the 19th century; and a photograph by Michael Nichols, from the 21st. Both of these works respond to a dualism in the human relationship to the wilderness, dating back at least to the European colonization of …

Grief Moves: An Embodied Artistic Inquiry Into Losing And Finding The Self, Joanna Taubeneck Dec 2018

Grief Moves: An Embodied Artistic Inquiry Into Losing And Finding The Self, Joanna Taubeneck

Creative Arts Therapies Theses

The purpose of this embodied artistic inquiry self-study was to investigate the role and felt-experience of grief during the process of professional identity loss. The use of this particular methodology offered the researcher an opportunity to use movement as the means towards both collecting and analyzing data so that the relationship between grief and identity transition could be sensed physically. Data was collected with a research consultant during six sessions of movement improvisations inspired by each of Elisabeth Kübler-Ross’ (1969) five stages of grief. The researcher and research consultant met six times as a result of their decision to include …
