Angel Outside The House: The New Woman In Brittish Periodicals 1890-1910, Lindsay Rosa

Graduate Thesis Collection

The New Woman described in short fiction and editorial articles in British periodicals not only presented the ideal New Woman to readers, but served to shape the perceptions of the reader depending on the demographic of the targeted reading audience for that specific periodical. The audience for specific British periodicals featuring the New Woman included conservative families whose youth saw the New Woman figure as a role model. The New Woman figure easily connected to readers, particularly young, female middle-class readers, who easily identified with her because she possessed similar socioeconomic characteristics. Just as there were many New Women characters …

Not Your Father’S Playboy, Not Your Mother’S Feminist Movement: Feminism In A Porn Culture, Rebecca Whisnant

Philosophy Faculty Publications

This chapter is about the state of contemporary feminism and how it relates to the porn culture that surrounds us. This is important because whatever porn culture is, and there are a variety of definitions, it's not what feminists, or women, or anybody with a lick of sense, ever meant by "sexual liberation." There have, however, been contentious debates between radical and liberal feminists about the relationship between pornography, power and choice. I aim to unravel some of those debates here and highlight how liberal notions of "choice," favored by self-proclaimed "third-wave feminists," confuse and undermine our thinking not only …

The Speaker: The Tradition And Practice Of Public Speaking, Joesph M. Valenzano Iii, Stephen W. Braden

Communication Faculty Publications

Speech is both a skill and a field of study. Today, however, the rich tradition of speech communication is either reduced to a few quick mentions of Aristotle and Cicero or lost altogether. Why have we forgotten this history, and more importantly, why are we not sharing these origins with our students?

This volume brings tradition to the forefront of public speaking instruction through the lens of skills-centered pedagogy. It will help students understand the “why” behind the “how” of effective public speaking.

How Artistic Creativity Is Possible For Cultural Agents, Aili W. Bresnahan

Philosophy Faculty Publications

Joseph Margolis holds that both artworks and selves are ”culturally emergent entities." Culturally emergent entities are distinct from and not reducible to natural or physical entities. Artworks are thus not reducible to their physical media; a painting is thus not paint on canvas and music is not sound.

In a similar vein, selves or persons are not reducible to biology, and thought is not reducible to the physical brain. Both artworks and selves thus have two ongoing and inseparable ”evolutions”—one cultural and one physical. Rather than having fixed ”natures” that remain stable for any purpose other than numerical identity, artworks …

Maximum Entropy Modeling Of Indiana Bat (Myotis Sodalis) Maternity Roost Habitat, Joseph Robert Lemen

Graduate Theses/Dissertations

Since 1967, the Indiana bat (Myotis sodalis) has been on the U.S. Endangered Species list due to disruption of hibernating bats in caves, summer habitat degradation, and more recently, the onset of White-nose Syndrome. The purpose of this study is to evaluate landscape variables associated with Indiana bat maternity roost trees in an attempt to better understand what factors play a role in their distribution in north central Missouri. I tracked reproductive female Indiana bats to 20 different primary and secondary roost trees; these are roosts that had multiple bats visit them on multiple occasions. GPS location data for these …

Functional Connection Between Yeast Dynamin And Retromer At The Endosome, Christopher Robert Trousdale

Graduate Theses/Dissertations

Intracellular trafficking from the late endosome to Golgi in cells is termed retrograde transport, essential for recycling of important macromolecules including cell membrane receptors. Retrograde transport is regulated by a family of proteins known as the "Retromer” composed of 5 VPS proteins (Vps5, Vps17, Vps26, Vps29, and Vps35). Retromer acts as the coat proteins for vesicles emerging from late endosomes. Loss of Retromer function has been previously implicated in both Parkinson's and Alzheimer's disease. Vps1, a yeast dynamin-like protein, plays a role in intracellular trafficking. Vps1 has been shown to localize at the endocytic sites to promote pinching off of …

Nesting Success And Parental Behavior Of The Prothonotary Warbler (Protonotaria Citrea) In Southwestern Missouri, Kathryn Marie Siverly

Graduate Theses/Dissertations

The breeding biology and singing rates of Prothonotary Warblers (Protonotaria citrea) were studied in southwestern Missouri in 2014 and 2015, using wooden nesting boxes. Data were collected on clutch and brood sizes, the numbers of young fledged, parental care and male singing rates. Five pairs were studied over the course of the two summers. Of 28 eggs laid, 14 young fledged. In 2015, significant flooding resulted in the loss of all young and eggs for that year. First clutches were larger than second clutches. Observations suggest females may contribute more to the care of offspring, in terms of foraging and …

Reintroduction Biology Of Head-Started Ornate Box Turtles, Eric R. Sievers

Graduate Theses/Dissertations

The ornate box turtle (Terrapene ornata) is a prairie-dwelling species that has experienced population declines, especially near the northern edge of its range. In order to provide supporting research for a reintroduction program at the Upper Mississippi River National Wildlife and Fish Refuge in northwestern Illinois, I compared the relative success of different approaches to reintroduction. Specifically, I tested the null hypothesis that reintroduced turtles exhibited equal reintroduction success when, 1) released at a site that is known to support a viable ornate box turtle population, 2) ‘soft-released' in a fenced enclosure at a site where very few ornate box …

Finding Consensus Energy Folding Landscapes Between Rna Sequences, Joshua Burbridge

Electronic Theses and Dissertations

In molecular biology, the secondary structure of a ribonucleic acid (RNA) molecule is closely related to its biological function. One problem in structural bioinformatics is to determine the two- and three-dimensional structure of RNA using only sequencing information, which can be obtained at low cost. This entails designing sophisticated algorithms to simulate the process of RNA folding using detailed sets of thermodynamic parameters. The set of all chemically feasible structures an RNA molecule can assume, as well as the energy associated with each structure, is called its energy folding landscape. This research focuses on defining and solving the problem of …

Adsorption Behaviour Of Polyacrylic Acid On Cerium Oxide Nanostructures: Experimental And Predictive Model, Ali Haghighat Mesbahi

Electronic Theses and Dissertations

Cerium oxide-based slurries are crucial for chemical mechanical polishing (CMP) in electronic industry. For these slurry systems, poly(acrylic acid) (PAA) is heavily utilized to provide colloidal stability. Some of the important parameters in the colloid stability are molecular weight (MW) and concentration of stabilizer, size of the nanoparticle in the slurry and the pH of system. By determining the colloidal stability of a discrete number of slurry formulations and relating these to certain slurry component parameters, a possible model can be produced to predict the influence of these parameters on the particle stability. Direct quantification of colloidal stability is difficult, …

Optimization Of Glycerol And Biodiesel Waste Prefermentation To Improve Ebpr, Marzieh Ghasemi

Electronic Theses and Dissertations

The enhanced biological phosphorus removal (EBPR) process efficiency relies on different operational and process conditions especially the type of carbon source available in the wastewater. Acetic acid and propionic acid are the two major volatile fatty acids (VFAs) found in domestic wastewater which can drive biological phosphorus (P) removal to the desired level. However, often domestic wastewater does not have a sufficient amount of VFAs. Due to high acetate and propionate production-cost, it is not economic to add acetate and propionate directly in full-scale wastewater treatment plants. This brought up the idea of using external carbon sources (e. g. molasses …

Compressive Sensing And Recovery Of Structured Sparse Signals, Behzad Shahrasbi

Electronic Theses and Dissertations

In the recent years, numerous disciplines including telecommunications, medical imaging, computational biology, and neuroscience benefited from increasing applications of high dimensional datasets. This calls for efficient ways of data capturing and data processing. Compressive sensing (CS), which is introduced as an efficient sampling (data capturing) method, is addressing this need. It is well-known that the signals, which belong to an ambient high-dimensional space, have much smaller dimensionality in an appropriate domain. CS taps into this principle and dramatically reduces the number of samples that is required to be captured to avoid any distortion in the information content of the data. …

Modeling Social Norms In Real-World Agent-Based Simulations, Rahmatollah Beheshti

Electronic Theses and Dissertations

Studying and simulating social systems including human groups and societies can be a complex problem. In order to build a model that simulates humans' actions, it is necessary to consider the major factors that affect human behavior. Norms are one of these factors: social norms are the customary rules that govern behavior in groups and societies. Norms are everywhere around us, from the way people handshake or bow to the clothes they wear. They play a large role in determining our behaviors. Studies on norms are much older than the age of computer science, since normative studies have been a …

Optimal Distribution Network Reconfiguration Using Meta-Heuristic Algorithms, Arash Asrari

Electronic Theses and Dissertations

Finding optimal configuration of power distribution systems topology is an NP-hard combinatorial optimization problem. It becomes more complex when time varying nature of loads in large-scale distribution systems is taken into account. In the second chapter of this dissertation, a systematic approach is proposed to tackle the computational burden of the procedure. To solve the optimization problem, a novel adaptive fuzzy based parallel genetic algorithm (GA) is proposed that employs the concept of parallel computing in identifying the optimal configuration of the network. The integration of fuzzy logic into GA enhances the efficiency of the parallel GA by adaptively modifying …

A New Paradigm Integrating Business Process Modeling And Use Case Modeling, Barclay Brown

Electronic Theses and Dissertations

The goal of this research is to develop a new paradigm integrating the practices of business process modeling and use case modeling. These two modeling approaches describe the behavior of organizations and systems, and their interactions, but rest on different paradigms and serve different needs. The base of knowledge and information required for each approach is largely common, however, so an integrated approach has advantages in efficiency, consistency and completeness of the overall behavioral model. Both modeling methods are familiar and widely used. Business process modeling is often employed as a precursor to the development of a system to be …

Applied Error Related Negativity: Single Electrode Electroencephalography In Complex Visual Stimuli, Benjamin Sawyer

Electronic Theses and Dissertations

Error related negativity (ERN) is a pronounced negative evoked response potential (ERP) that follows a known error. This neural pattern has the potential to communicate user awareness of incorrect actions within milliseconds. While the implications for human-machine interface and augmented cognition are exciting, the ERN has historically been evoked only in the laboratory using complex equipment while presenting simple visual stimuli such as letters and symbols. To effectively harness the applied potential of the ERN, detection must be accomplished in complex environments using simple, preferably single-electrode, EEG systems feasible for integration into field and workplace-ready equipment. The present project attempted …

Resource Management In Large-Scale Systems, Ashkan Paya

Electronic Theses and Dissertations

The focus of this thesis is resource management in large-scale systems. Our primary concerns are energy management and practical principles for self-organization and self-management. The main contributions of our work are: 1. Models. We proposed several models for different aspects of resource management, e.g., energy-aware load balancing and application scaling for the cloud ecosystem, hierarchical architecture model for self-organizing and self-manageable systems and a new cloud delivery model based on auction-driven self-organization approach. 2. Algorithms. We also proposed several different algorithms for the models described above. Algorithms such as coalition formation, combinatorial auctions and clustering algorithm for scale-free organizations of …

Stability And Control In Complex Networks Of Dynamical Systems, Saeed Manaffam

Electronic Theses and Dissertations

Stability analysis of networked dynamical systems has been of interest in many disciplines such as biology and physics and chemistry with applications such as LASER cooling and plasma stability. These large networks are often modeled to have a completely random (Erdös-Rényi) or semi-random (Small-World) topologies. The former model is often used due to mathematical tractability while the latter has been shown to be a better model for most real life networks. The recent emergence of cyber physical systems, and in particular the smart grid, has given rise to a number of engineering questions regarding the control and optimization of such …

Worldwide Infrastructure For Neuroevolution: A Modular Library To Turn Any Evolutionary Domain Into An Online Interactive Platform, Paul Szerlip

Electronic Theses and Dissertations

Across many scientific disciplines, there has emerged an open opportunity to utilize the scale and reach of the Internet to collect scientific contributions from scientists and non-scientists alike. This process, called citizen science, has already shown great promise in the fields of biology and astronomy. Within the fields of artificial life (ALife) and evolutionary computation (EC) experiments in collaborative interactive evolution (CIE) have demonstrated the ability to collect thousands of experimental contributions from hundreds of users across the glob. However, such collaborative evolutionary systems can take nearly a year to build with a small team of researchers. This dissertation introduces …

Enhanced Microwave Hyperthermia Using Nanoparticles, Maryory Urdaneta

Electronic Theses and Dissertations

In this dissertation a study of enhanced hyperthermia for cancer treatment through the use of magnetic nanoparticles is presented. Hyperthermia has been in use for many years, as a potential alternative method in cancer treatment, and high frequency microwave radiation has been used successfully to raise the tumor temperature to around 42°C in superficial tumors without causing damage to surrounding healthy tissues. Magnetic fluid hyperthermia involves the use of magnetic nanoparticles injected into the tumor before exposure to microwave radiation. The magnetic energy in the nanoparticles is converted into heat allowing for a more rapid rise of temperature in the …

Life-Cycle Greenhouse Gas Emissions And Water Footprint Of Residential Waste Collection And Management Systems, Mousa Maimoun

Electronic Theses and Dissertations

Three troublesome issues concerning residential curbside collection (RCC) and municipal solid waste (MSW) management systems in the United States motivated this research. First, reliance upon inefficient collection and scheduling procedures negatively affect RCC efficiency, greenhouse gas (GHG) emissions, and cost. Second, the neglected impact of MSW management practices on water resources. Third, the implications of alternative fuels on the environmental and financial performance of waste collection where fuel plays a significant rule. The goal of this study was to select the best RCC program, MSW management practice, and collection fuel. For this study, field data were collected for RCC programs …

A Generic Framework For Multi-Method Modeling And Simulation Of Complex Systems Using Discrete Event, System Dynamics And Agent Based Approaches., Konstantinos Mykoniatis

Electronic Theses and Dissertations

Decisions about Modeling and Simulation (M&S) of Complex Systems (CS) need to be evaluated prior to implementation. Discrete Event (DE), System Dynamics (SD), and Agent Based (AB) are three different M&S approaches widely applied to enhance decision-making of complex systems. However, single type M&S approaches can face serious challenges in representing the overall multidimensional nature of CS and may result in the design of oversimplified models excluding important factors. Conceptual frameworks are necessary to offer useful guidance for combining and/or integrating different M&S approaches. Although several hybrid M&S frameworks have been described and are currently deployed, there is limited guidance …

Research On High-Performance And Scalable Data Access In Parallel Big Data Computing, Jiangling Yin

Electronic Theses and Dissertations

To facilitate big data processing, many dedicated data-intensive storage systems such as Google File System(GFS), Hadoop Distributed File System(HDFS) and Quantcast File System(QFS) have been developed. Currently, the Hadoop Distributed File System(HDFS) [20] is the state-of-art and most popular open-source distributed file system for big data processing. It is widely deployed as the bedrock for many big data processing systems/frameworks, such as the script-based pig system, MPI-based parallel programs, graph processing systems and scala/java-based Spark frameworks. These systems/applications employ parallel processes/executors to speed up data processing within scale-out clusters. Job or task schedulers in parallel big data applications such as …

Pressurized Metal Bellows Shock Absorber For Space Applications., John Trautwein

Electronic Theses and Dissertations

Numerous spacecraft designs exist for exploring the surfaces of planetary bodies and each have their own advantages and disadvantages. All successful landings have been made by stationary landers or wheeled rovers that rely on one-time use mechanisms, such as crushable aluminum honeycomb shock absorbers or inflatable airbags, to reduce shock loading to the spacecraft during landing. The stationary lander is the simplest type of lander, but can only take data from one location. Wheeled rovers add complexity in exchange for mobility to explore different locations. Rovers are limited by the terrain they can traverse; rovers becoming stuck have ended missions. …

Learning To Combat Chronic Pain: Exploring The Effectiveness Of A Six-Week Patient Psychoeducation Course Teaching Self-Management Of Chronic Pain, Serita Backstrand

Doctor of Psychology (PsyD)

Abstract Chronic pain is a highly prevalent health problem in the U.S. and poses a large economic and temporal cost to the medical system (Institute of Medicine, 2011; Marcus, 2003). Patients with chronic pain typically report a decrease in emotional, social, and economic functioning (Bair et. al, 2009; Breen, 2002; Kang, Backstrand, & Parker, 2013). This study investigated the efficacy of a 6-week evidence-based group psychoeducation course for the self-management of chronic pain. Pre- and post-test measures were utilized to assess results of the course. Data were analyzed using a paired sample t-test in order to explore the relationship and …

Impact Of A Cognitive Behavioral Pain Management Group On Depression, Anxiety, Pain Severity, And Opioid Use In An Inpatient Population, Breanna Bocciolatt

Doctor of Psychology (PsyD)

Chronic pain has significant, multifaceted effects on both the health care system and the individual. The total cost of pain to the U.S. healthcare system is estimated to be over $600 billion annually (Skinner, Wilson, & Turk, 2012). People with chronic pain may frequent multiple providers, often dominating the time and resources of healthcare professionals (Skinner et al., 2012). The approximately 100 million people with chronic pain miss work, experience financial distress, and strained relationships, which leads to comorbid psychological diagnoses (Birnie, McGrath, & Chambers, 2012). Pain treatment strategies have largely followed a biomedical framework, seeking to identify the source …

Activating Race: Race Priming In An Undergraduate Population, Amber L. Nelson

Doctor of Psychology (PsyD)

Can a race priming intervention improve evaluations of college scholarship applicants? Building on the work of Sanchez and Bonam (2009), the present study was designed to examine how evaluations of warmth, competence, and scholarship worthiness, change as a result of race priming and stereotype activation. The hypothesis was that race priming and stereotype activation would cause participants to consider how they may apply stereotypes in their judgments of candidates, resulting in a positive shift in their evaluations on dimensions of warmth, competence, and scholarship worthiness following a race priming intervention. Participants across three studies included 228 undergraduate students, and 24 …

The Effects Of A Grace Intervention In A Christian Congregation: A Study Of Positive Psychology In The Church, Jeff A. Moody

Doctor of Psychology (PsyD)

There are certain virtues or character strengths that promote well-being in a person’s life. Positive psychology research has examined these characteristics, but not within spiritual and religious contexts. It has been demonstrated that involvement in religious life contributes to overall well-being. There is an absence of research examining the influence of spirituality on positive psychology variables. Within the Christian tradition, grace is considered to be a catalyzing element which leads to transformation in the Christian’s character and relationships. It was hypothesized that a successful grace intervention within a Christian faith community would lead to increases in the awareness and enactment …

Mathematical Modeling Of Carbon Removal In The A-Stage Activated Sludge System, Thomas Nogaj

Electronic Theses and Dissertations

This research developed a dynamic activated sludge model (ASM) to better describe the overall removal of organic substrate, quantified as chemical oxygen demand (COD), from A-stage high rate activated sludge (HRAS) systems. This dynamic computer model is based on a modified ASM1 (Henze et al., 2000) model. It was determined early in the project that influent soluble COD, which is normally represented by a single state variable in ASM1, had to be subdivided into two state variables (SBs and SBf, or slow and fast fractions) to simulate the performance of A-stage systems. Also, the addition of state variables differentiating colloidal …
