Toward A Theory Of Safe Passage: Agentic Practices Of Women Writers Who Teach, Lillian Gordon Reeves

Theses and Dissertations

Past studies show that narrative is an effective tool for guiding teachers to develop teacher identity, to recognize their practical knowledge, and to engage in teacher transformation, especially during initial teacher training and the early years of their career. Consequently, other researchers have identified how narrative studies inform what we know about teachers’ identities, their practical knowledge, and their transformations during initial training and early career teaching. However, we do not know how narrative functions in the experiences of teachers beyond initial teacher training and early career teaching. This study intends to fill this gap in the research. In this …

Essays On Battle Clusters In Internal Armed Conflicts And Insurgencies: Concept, Causes And Consequences, Chifeng Liu

Theses and Dissertations

With the purpose to re-conceptualize the intensity of internal armed conflicts, I argue that the characteristics such as location, scale and duration of “major battlefields,” i.e. the spatio-temporal clusters of combat events are important in the evaluation of impact of modern civil wars and insurgencies. I start with elaborating and constructing a new concept of conflict magnitude with battle clusters using up-to-date geo-referenced data and spatial statistic methods. In the second article, I first explain the location and duration of major battlefields. The findings indicate that an area with multiple non-state armed groups (NSAGs) is more likely to become main …

The Poetic Works Of Charlotte Smith: Philosophy, Sympathy, And Forging Community, Jessica Danielle Castillo

Theses and Dissertations

This work will focus on Charlotte Smith’s poetic works and how, over the course of her entire poetic career (the late eighteenth century/early nineteenth century), she exhibits a concrete sense of a poetic ethos regarding sympathy in her writing. I seek to account for the overwhelming focus on suffering subjects by illuminating her view of the relation between poetry and sympathy for others. I will also place her within a history of writers and philosophers who examined the epistemological and practical nature of feeling, sympathy, and emotional connection among human beings. Smith feels that poetry renders suffering visible to others, …

Culturally Relevant Pedagogy: Study Abroad To Teaching Internship, Melanie G. Keel

Theses and Dissertations

Culturally relevant pedagogy (Ladson-Billings, 1995a; Gay, 2010) and culturally sustaining pedagogy (Paris, 2012; Paris & Alim, 2014; Ladson-Billings, 2014) are urgent needs in classrooms because of the diverse student population teachers serve. This research is grounded in critical race theory (CRT) (Delgado & Stefancic, 2001; Bell 1995) and culturally relevant pedagogy (CRP) (Gay, 2010; Gay & Howard, 2000; Ladson-Billings, 1995a & 1995b) as lenses to interrogate a White pre-service teacher’s internship in the United States and a study abroad (Cushner, 2007; Keengwe, 2010; Malewski, Sharma, & Phillion, 2012) experience in Ecuador. During a 25 day study abroad that included daily …

A Three-Dimensional-Engineered Matrix To Study The Microenvironment Of Cancer Stem Cells, Samaneh Kamali Sarvestani

Theses and Dissertations

Maintenance of cancer stem cells (CSCs) is regulated by their microenvironment. As cancer cells are affected by many factors in their microenvironment, a major challenge is to isolate the effect of a specific factor on CSCs while keeping other factors unchanged. We developed a synthetic inert 3D Poly Ethylene Glycol Di-Acrylate (PEGDA) gel culture system as a unique tool to study the effect of microenvironmental factors on CSCs response. Synthetic hydrogels provide the flexibility to design three-dimensional (3D) matrices to isolate and study individual factors in the tumor microenvironment. The first objective of this work was to investigate the effect …

Automatic Loop Tuning And Memory Management For Stencil Computations, Fan Zhang

Theses and Dissertations

The Texas Instruments C66x Digital Signal Processor (DSP) is an embedded processor technology that is targeted at real time signal processing. It is also developed with a high potential to become the new generation of coprocessor technology for high performance embedded computing. Of particular interest is its performance for stencil computations, such as those found in signal processing and computer vision tasks. A stencil is a loop in which the output value is updated at each position of an array by taking a weighted function of its neighbors. Efficiently mapping stencil-based kernels to the C66x device presents two challenges. The …

Perception Of Police In Public Housing Communities, Taylor Brickley

Theses and Dissertations

Research on the relationship between police and citizens consistently finds that attitudes toward police (ATP) are least positive among black citizens in areas of concentrated disadvantage. While much of the research in this area focuses specifically on ATP among young black males in low-income communities because they have the most contact with police, there has been relatively little research that has included older and/or female residents. Additionally, research has yet to examine ATP in racial and economic enclaves that may have different social and environmental characteristics than the surrounding community. This study utilizes in-depth interviews with 60 residents of two …

The Influence Of Parent Portal Access On Student Efficacy And Parental Involvement, Shannon D. Dries

Seton Hall University Dissertations and Theses (ETDs)

This study examined the influence of Parent Portal access on student achievement and parental involvement defined as home-to-school communication. The population was students in sixth grade in a suburban district in New Jersey. Academic achievement was defined through GPA at the end of sixth grade and performance on the New Jersey Assessment of Skills and Knowledge (NJ ASK) in both Math and Language Arts Literacy in Grade 6. Attendance was measured using attendance rates. Parental involvement was measured by the number of parent logins to Parent Portal. Multiple regression analyses, backward entry method, were used to determine the influence of …

Approximation And Relaxation Approaches For Parallel And Distributed Machine Learning, Stephen Tyree

McKelvey School of Engineering Graduate Student Theses & Dissertations

Large scale machine learning requires tradeoffs. Commonly this tradeoff has led practitioners to choose simpler, less powerful models, e.g. linear models, in order to process more training examples in a limited time. In this work, we introduce parallelism to the training of non-linear models by leveraging a different tradeoff--approximation. We demonstrate various techniques by which non-linear models can be made amenable to larger data sets and significantly more training parallelism by strategically introducing approximation in certain optimization steps.

For gradient boosted regression tree ensembles, we replace precise selection of tree splits with a coarse-grained, approximate split selection, yielding both faster …

Reduced Astrocyte Viability At Physiological Temperatures From Magnetically Activated Iron Oxide Nanoparticles, Nicholas J. Schaub, Deniz Rende, Yuan Yuan, Ryan J. Gilbert, Diana Andra Borca-Tasciuc

Chemical and Biochemical Engineering Faculty Research & Creative Works

Superparamagnetic iron oxide nanoparticles (SPIONs) can generate heat when subjected to an alternating magnetic field (AMF). In the European Union, SPIONs actuated by AMF are used in hyperthermia treatment of glioblastoma multiforme, an aggressive form of brain cancer. Current data from clinical trials suggest that this therapy improves patient life expectancy, but their effect on healthy brain cells is virtually unknown. Thus, a viability study involving SPIONs subjected to an AMF was carried out on healthy cortical rat astrocytes, the most abundant cell type in the mammalian brain. The cells were cultured with amino silane- or starch-coated SPIONs with or …

Film Tourism: The Pre-Production Perspective. A Case Study Of Visit Somerset And The Hollywood Story Of Glastonbury., Na Semley, G Busby

Plymouth Business School

Film tourism has been researched now for many years and the consequences of post-production are clear. However, there has been little opportunity to explore the perceptions of filming, pre-production, until now. Using a case study approach to the making of one particular Hollywood film on a rural location, the paper focuses on evaluating the business of film tourism and establishing the perceived impacts of film tourism from advanced practitioners and local residents, respectively. Two stages of data collection were adopted during pre-production: elite interviews and focus groups. The findings reveal that the role of each practitioner shapes their level of …

Workplace Harassment: A Cross-Jurisdictional Comparative Analysis Of Legislative Responses To This Workplace Phenomenon In Canada, Kayla Alice Carr

LLM Theses

This thesis investigates different statutory models Canadian legislatures have enacted to address workplace harassment. It adopts a qualitative, comparative case study approach, providing an in-depth comparative analysis of legislation from Québec, Saskatchewan, Ontario, Manitoba and British Columbia. Through this analysis, this thesis outlines the ways in which workplace harassment has been regulated in Canada, why that model was adopted by the jurisdiction and how that model measures against other models for legislating workplace harassment. Through an examination of existing literature relating to workplace harassment stemming from three theoretical paradigms and an analysis of a model legislative framework, this thesis creates …

The Influence Of Confucianism On Identity Formation Of A Multi-Skilled Migrant: An Autoethnography, Annabella Fung

The Qualitative Report

In this autoethnographical study, I examine how my identities were influenced by Confucianism. Two main Confucian concepts were examined: “selfperfection,” and “filial piety and submissiveness.” As a migrant who left Macau for Australia at fifteen, I have been immersed in diverse cultural climates, experienced gender bias, identity crisis and racial discrimination. I consider all experiences as essential steps of my evolution with ethnographic, interpretative, phenomenological and narrative understandings. This paper introduces the term “seasonal fluctuations” as a way to describe the changing meanings of my lived experiences that were interrogated by my three distinctive personalities: The Writer, The Interpreter and …

What's Wrong With Me?: An Autoethnographic Investigation Of The Co-Cultural Communicative Practices Of Living With Tourette Syndrome During Adolescence, Mark Congdon Jr.

The Qualitative Report

Using an Autoethnographic methodology, this essay explores how I was diagnosed with Tourette Syndrome. My experience illustrates a dynamic and difficult process of understanding and negotiating assimilation, using a variety of communication strategies related to self-perception, perceptions of others, and interactions with others. Using Co-Cultural theory (CCT) as a theoretical framework, three themes emerged from my experience: (1) nonassertive assimilation: negotiating with relationships of authority, (2) aggressive assimilation: negotiating relationships with peers, and (3) nonassertive separation: the convergence of negotiating relationships of authority and with peers. It is my hope that my story expands the awareness and conversation among and …

The Foundlings, Nadia Adams

Theses

The Foundlings is an exploration of memory and absence through the use of found objects and photographs. In this thesis, memory is understood through the use of the domestic space and the objects found within. The relationship of photography to memory is an integral part of this work. Specifically in the use of found and constructed imagery as related to the family album. The Foundlings uses sculpture, painting, photography, and projection to understand the place of the individual in both a contemporary and historical context.

A Liberal State Of Mind: Formal Reconstructions Of Statehood In The Anglophone African Novel, Maya Ganapathy

Arts & Sciences Graduate Student Theses and Dissertations

While the idea of the nation and national identity is often taken as the starting point for examinations of the African state, this dissertation explores the transnational dimensions of the African novel and the way in which English-language writers from Africa imagine a state that more adequately captures their desire to freely inhabit a global literary marketplace. Although critics of the Anglophone African novel tend to understand the fictional state as an object of unremitting political critique (often simply as a reflection of its real-world counterpart), the African state, when viewed through the methodological lens of narrative form, becomes the …

Modulation Of Nmda Receptor Activity During Physiological And Pathophysiological Events, Christine Marie Emnett

Arts & Sciences Graduate Student Theses and Dissertations

N-methyl-D-aspartate receptors (NMDARs) are ionotropic glutamate receptors that serve crucial signaling and neurotrophic functions throughout the central nervous system. Both hyperfunction and hypofunction of NMDARs are associated with neurological and neuropsychiatric conditions. Thus, both positive and negative pharmacological NMDAR modulators are of clinical interest as treatments. Understanding drug mechanisms could lead to more rational drug design. Memantine and ketamine are NMDAR open channel blockers that exhibit similar pharmacodynamics at NMDARs but have different clinical uses. Memantine improves cognitive decline during Alzheimer's disease. Ketamine is an anesthetic and analgesic with psychotomimetic effects, but it is also a rapid acting and long-lived …

Accelerating Heuristic Search For Ai Planning, You Xu

McKelvey School of Engineering Graduate Student Theses & Dissertations

AI Planning is an important research field. Heuristic search is the most commonly used method in solving planning problems. Despite recent advances in improving the quality of heuristics and devising better search strategies, the high computational cost of heuristic search remains a barrier that severely limits its application to real world problems. In this dissertation, we propose theories, algorithms and systems to accelerate heuristic search for AI planning.

We make four major contributions in this dissertation. First, we propose a state-space reduction method called Stratified Planning to accelerate heuristic search. Stratified Planning can be combined with any heuristic search to …

Kinetic Analysis And Inhibition Studies Of Iron-Dependent Histone Demethylases, Barbara Gordon Cascella

Arts & Sciences Graduate Student Theses and Dissertations

The research presented herein focuses on the kinetics and inhibition of the KDM4 subfamily of Jumonji C (JmjC) domain-containing histone demethylases (HDMs). Belonging to the larger class of alpha-ketoglutarate (alpha-KG)-dependent, non-heme iron monooxygenases, the JmjC-HDMs remove methyl groups from mono-, di-, and tri-methylated histone lysine residues through an Fe(IV)-oxo-catalyzed hydroxylation reaction. JmjC-HDMs have been found to play integral roles in the maintenance of genomic integrity as well as in the regulation of transcription. Three KDM4 members were studied: the mixed H3K9/H3K36 demethylases KDM4A and KDM4C, and the pure H3K9 demethylase KDM4E. KDM4C is a hypoxia-inducible factor 1 (HIF-1) target gene …

Real-Time Temperature Imaging Using Ultrasonic Change In Backscattered Energy, Weiyuan Zhao

McKelvey School of Engineering Graduate Student Theses & Dissertations

Thermal therapy from low-temperature cryosurgery to high-temperature ablation of tumors and unwanted electrical pathways has gained increased attention. Temperature imaging (TI) from magnetic resonance studies is the de facto standard for volumetric estimation of temperature. Ultrasound has the advantages of being cheap, portable, non-invasive and non-ionizing. Our group showed in predictions for single scatterers, simulations of scatterer populations and measurements in 1D, 2D and 3D, that CBE changed monotonically with temperature with 1^oC accuracy. An obstacle to clinical application of CBE TI is estimation of temperature in real time, which is limited by time for motion compensation (MC). …

The Effects Of Gamifying Optional Lessons On Motivation, Aaron Zemach

McKelvey School of Engineering Graduate Student Theses & Dissertations

Adding video-game elements to non-video-game interfaces (“gamification”) has become a common engagement strategy over the past several years in the domain of education. While prior studies have found that adding game elements to mandatory educational materials can increase students’ motivation to complete the materials, there has yet to be a study to investigate if game elements can make users more likely to engage with optional educational materials. In this study, we investigate whether users of a gamified educational interface are more motivated than users of a non-gamified interface to voluntarily complete educational materials. We found users of a gamified interface …

Modeling Algorithm Performance On Highly-Threaded Many-Core Architectures, Lin Ma

McKelvey School of Engineering Graduate Student Theses & Dissertations

The rapid growth of data processing required in various arenas of computation over the past decades necessitates extensive use of parallel computing engines. Among those, highly-threaded many-core machines, such as GPUs have become increasingly popular for accelerating a diverse range of data-intensive applications. They feature a large number of hardware threads with low-overhead context switches to hide the memory access latencies and therefore provide high computational throughput. However, understanding and harnessing such machines places great challenges on algorithm designers and performance tuners due to the complex interaction of threads and hierarchical memory subsystems of these machines. The achieved performance jointly …

An Essential Role For Self-Pmhc Throughout The Life Of A Cd4 T Cell: Contributions In The Thymus And Periphery, Stephanie Rodriguez

Arts & Sciences Graduate Student Theses and Dissertations

It is well established that self-peptide Major Histocompatibility Complexes (hereafter self-pMHC) are essential for the development of a broad repertoire of mature, self-tolerant CD4 and CD8 T cells. Despite clear knowledge that the pool of self-ligands is critical for positive and negative selection, the exact kinetics and dynamic nature of thymocyte interaction with self-pMHC class II (self-pMHCII) bearing antigen-presenting cells (APCs) during development is still largely a mystery. The enigmatic nature of selecting self-pMHC is not unique to the thymic environment; increasingly evident is the dependence of peripheral T cells on extra-thymic self-pMHC expression, specifically selecting self-pMHC, for their homeostatic …

Contextualized Robot Navigation, David Vincent Lu

McKelvey School of Engineering Graduate Student Theses & Dissertations

In order to improve the interaction between humans and robots, robots need to be able to move about in a way that is appropriate to the complex environments around them. One way to investigate how the robots should move is through the lens of theatre, which provides us with ways to analyze the robot's movements and the motivations for moving in particular ways. In particular, this has proven useful for improving robot navigation. By altering the costmaps used for path planning, robots can navigate around their environment in ways that incorporate additional contexts. Experimental results with user studies have shown …

The Synchronized Filtering Dataflow, Peng Li

McKelvey School of Engineering Graduate Student Theses & Dissertations

In the past decade, the world has seen the rise of big data, which calls for a paradigm shift in data processing. Streaming processing, where data are processed in their spatial or temporal order, is increasingly common. Meanwhile, parallel computing has become a household term in the computing world. The combination of streaming processing and parallel computing, streaming computing, has been playing an important role in data processing.

A streaming computing system is a network of nodes connected by unidirectional first-in first-out (FIFO) data channels. When a node has multiple input channels, to ensure the deterministic behavior of the whole …

Novel Mobile Computation Offloading Framework For Android Devices, Meng Wang

McKelvey School of Engineering Graduate Student Theses & Dissertations

The thesis implements an offloading framework for GoogleTM AndroidTM based on mobile devices. Today, the full potential for smartphones may be constrained by certain technical limits such as battery endurance and computational performance. Modern mobile applications own more powerful functions but need larger computation and faster frame rate, which consume more battery energy. Using the proposed offloading framework, mobile devices can offload computational intensive workload to servers to save battery energy consumption and reduce the execution time. The framework can also enable software developers to easily build and deploy services on the servers to support mobile devices to run computationally …

Feeling Doctrine: Religious Meanings Of Emotion In Sixteenth-Century German Literature, Georgia Anna Leeper

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation explores the intersections of emotion and Protestant theology in late-16th-century German literature. The project demonstrates the availability of even secular texts to confessional readings through the analysis of representations of emotions. Post-Reformation texts practice an emotional exemplarity that highlights the effects - including the spiritual effects - which emotional experiences have on the individual. I argue that narrative representations of emotions at this moment reflect anxieties about the nebulous nature of faith, and its central role in Protestant salvation. Close readings of widely-read texts such as the 1587 Faustbuch, Melusine, and Hans Sach's Judith: ein Comedi, among others …

When Life Happens: Theatres Of Hiv And Complexity In South Africa, Jessica S. Ruthven

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation examines theatre as part of an artistic movement in South Africa to address the social, structural, and emotional repercussions of HIV, as well as a space in which knowledge about HIV/AIDS is actively created, mediated, reproduced, challenged, and presented for public consumption. Although applied theatre has a long history in the country, I focus on innovation in recent theatrical practices that have occurred as artists and members of broader civil society struggle to understand the trajectory of the country's AIDS epidemic and question the scope of popular national HIV intervention campaigns. I use emerging forms of cultural production …
