The Morally Contaminating (And Motivating) Influence Of Hate Groups In The U.S., Andrew L. Stewart

Master's Theses

A growth in the number of hate groups that operate in the United States over the past decade counters many researchers’ claims that overt prejudice and discrimination no longer have influence. In this thesis, we explore how people react with moral outrage and moral cleansing toward hate groups’ moral transgressions of racial egalitarianism—a strong sacred value among those who desire group-based equality. Across two experiments, we find that people perceive hate groups as immoral social agents, and people express moral outrage against them. We also find that people who were morally contaminated by hate groups (i.e., by being led to …

Comparison Of An Ultrasonic And A Non-Ultrasonic Endodontic Irrigation Protocol: A Clinical Study, Christopher M. Beus

Master's Theses

The use of irrigation as a method of rendering canals bacteria free continues to be a source of investigation. Recent data suggests that an activated irrigation protocol such as passive ultrasonic irrigation can result in decreased intracanal bacteria. In addition, studies have shown that the activation of various irrigants such as NaOCl and Chlorhexidine can increase the sum antimicrobial effect. The purpose of this randomized, double blinded, prospective in-vivo clinical study was to compare the results of a non-activated irrigation protocol (NAI) using only NaOCl 1.5% to a passive ultrasonic irrigation protocol (PUI) using NaOCl 1.5%, EDTA 17% and Chlorhexidine …

Correlations Between Body Composition Components And Bone Mineral Content In Untrained Young Men And Women, Erin L. Burtner

Master's Theses

PURPOSE: Low bone mineral content has been linked to the development of osteoporosis in humans. Research is divided as to whether fat or lean mass plays a more significant role in the development of bone mass. Physical activity has also been shown to increase bone mineral content in adolescents and combat the loss of bone density with aging. The purpose of this study was to examine correlations that exist between bone mineral content and anthropometric and performance measurements in untrained young men and women. METHODS: 78 untrained males (age 22.3±3.7) and 56 females (age 22.8±3.7) completed a battery of baseline …

Modulation Of Hypoglossal Motoneurons By Nitric Oxide, Justin Philip Benoit

Master's Theses

Obstructive sleep apnea (OSA)- the occurrence of repetitive episodes of airway obstruction during sleep- is considered a major health problem affecting up to 9% of adults in the United States (Parish & Somers, 2004). The hypoglossal motor nucleus (HMN) controls genioglossus muscle tone and is critically important for maintaining airway patency; loss of excitatory input to the HMN during sleep results in disfacilitation of hypoglossal motoneurons, increased airway resistance and contributes to the development of OSA (Horner R. L., 2007). However, a fundamental question of sleep medicine that remains unresolved is what mechanisms help maintain airway patency during sleep? A …

Interoperation For Lazy And Eager Evaluation, William Jeffrey Faught

Master's Theses

Programmers forgo existing solutions to problems in other programming lan- guages where software interoperation proves too cumbersome; they remake so- lutions, rather than reuse them. To facilitate reuse, interoperation must resolve language incompatibilities transparently. To address part of this problem, we present a model of computation that resolves incompatible lazy and eager eval- uation strategies using dual notions of evaluation contexts and values to mirror the lazy evaluation strategy in the eager one. This method could be extended to resolve incompatible evaluation strategies for any pair of languages with common expressions.

Sponges Of The Caribbean: Linking Sponge Morphology And Associated Bacterial Communities, Ericka Ann Poppell

Master's Theses

The ecological and evolutionary relationship between sponges and their symbiotic microflora remains poorly understood, which limits our ability to understand broad scale patterns in benthic-pelagic coupling on coral reefs. Previous research classified sponges into two different categories of sponge microbial associations: High Microbial Abundance (HMA) and Low Microbial Abundance (LMA) sponges. Choanocyte chamber morphology and density was characterized in representatives of HMA and LMA sponges using scanning electron microscopy from freeze-fractured tissue. Denaturing Gradient Gel Elextrophoresis was used to examine taxonomic differences among the bacterial communities present in a variety of tropical sponges. The results supported the hypothesis that choanocyte …

A Theoretical Analysis Of Referee Bias In Youth Hockey, Winston Christopher Pappas

Master's Theses

This research addressed the issue of youth hockey referee bias demonstrated throughout 286 CCYHL Squirt A and C league games and the 2009-2010 CDYHL Squirt B league season games. Structural functionalism, cognitive dissonance, and exchange theory were used to explain a probable rationale for biased referee behavior. A T-test revealed a mean of .012, suggesting penalty calls were equalized during squirt level hockey games (age 9 through 10). A logistic regression analysis was incorporated to uncover predictable patterns of penalty calls made by referees based on penalty differential, score difference, and home team lead. Findings indicate that teams with the …

The Art Of Kente: History, Designs, And Drafts, Rhonda D. Crosman

Master's Theses

Kente is a traditional ceremonial strip-woven cloth made by the Asante and Ewe people of Ghana and Togo. This thesis examined the history, patterns, design elements, symbolism, and evolutionary changes of the kente textile tradition. Basic weaving information, illustrations, and color photographs necessary for the understanding of kente were provided. The thesis also analyzed weaving drafts for the creation of kente-like cloth on a contemporary Western style floor loom.

Tri-State Boolean Satisfiability With Commit: An Efficient Partial Solution Using Hyperlogic, Kevin Michael Byrd

Master's Theses

We present two implementation enhancements for the Boolean satisfiability problem and one visualization technique. The first is an expansion to a tri-nary logic system with a commit phase. The three states are (1) true, (2) false, and (3) don't care. We abstracted the operations of AND and OR to this hyperlogic system in a novel way. The commit phase works on one variable at a time and transitions values from temporary to permanent whenever possible. We viewed tri-state logic as a hyperspace above the binary (Boolean) logic. The second improvement is algorithmic. We modified the semantics of the classic 3 …

Parental Struggles With Obtaining Services For Children With Special Needs, Regina Lynn Carr

Master's Theses

This thesis is an in-depth review of the literature addressing parental struggles, attitudes, and perceptions of barriers in obtaining services for young children with special needs. Researchers, policy makers, and educators need to be aware of how families identify and report their experiences with obtaining services for their young children. Service providers for young children and families with special needs must understand the perspective of the family in order to better serve the children and families. Implementations for future research, practice, and policy changes are discussed.

Sex Role Egalitarianism And Relational Aggression In Intimate Partnerships, Emily Elizabeth Prather

Master's Theses

Intimate partner violence (IPV) is a serious problem with vast medical, psychological, financial, and social costs. Research indicates that IPV is particularly common among college students, however, little is known about relational aggression in this population. This study aimed to improve our understanding of relational aggression in the context of romantic relationships in a college sample by focusing on the potential roles of gender, sex role egalitarianism, acceptance of couple violence, and trait anger. As expected, trait anger was positively correlated with relational aggression. Acceptance of couple violence predicted the perpetration of relational aggression above and beyond the effects of …

Fraction-Free Methods For Determinants, Deanna Richelle Leggett

Master's Theses

Given a matrix of integers, we wish to compute the determinant using a method that does not introduce fractions. Fraction-Free Triangularization, Bareiss’ Algorithm (based on Sylvester’s Identity) and Dodgson’s Method (based on Jacobi’s Theorem) are three such methods. However, both Bareiss’ Algorithm and Dodgson’s Method encounter division by zero for some matrices. Although there is a well-known workaround for the Bareiss Algorithm that works for all matrices, the workarounds that have been developed for Dodgson’s method are somewhat difficult to apply and still fail to resolve the problem completely. After investigating new workarounds for Dodgson’s Method, we give a modified …

Evaluating Parenting Practices As A Mediating Factor Between Marital Conflict And Children's Adjustment, Kristin Lee Tyson

Master's Theses

A wealth of research has illustrated that negative parenting practices mediate the relation between destructive marital conflict and externalizing problems in children; however, the study of constructive marital conflict and adjustment problems in children is less developed. Research has also suggested that psychological control is related to children's behavior; however, previous research is unclear as to the specific relationship between marital conflict and children's internalizing and externalizing behavior. To address this gap, the present study examined positive and negative parenting practices and psychological control as mediators of constructive and destructive marital conflict and children's internalizing and externalizing problems. Married mothers …

I Don't Know Why You Say Goodbye, I Say Hello: Concepts Of Place In Eudora Welty's The Optimist's Daughter And Elizabeth Bowen's The Death Of The Heart, Emily Frances Cooley

Master's Theses

The Optimist's Daughter and The Death of the Heart reveal that, for Eudora Welty and Elizabeth Bowen, place is· more than mere landscape. Place is both the scene upon which their novels unfold and the means by which they convey their abstract understandings of the world. Place provides the physical settings of their stories, but it also reveals something about their psyche or symbolic language. The settings used by Welty in The Optimist's Daughter reinforce traditional notions of place in Southern life and society whereas the settings employed by Bowen in The Death of the Heart exhibit a partiality for …

Metaphasia: Shelley And The Language Of Remoter Worlds, Michael Andrew Howell

Master's Theses

The aim of this project was to trace the evolution of Percy Shelley's metaphasic narrative, or language of the dead, chronologically through the Hymn to Intellectual Beauty, Mont Blanc, and Prometheus Unbound. Proceeding from Earl Wasserman's detailed map of Shelley's mythopoeic structure, I charted this evolution while identifying a fifth discrete entity within the mythological hierarchy of what Harold Bloom has characterized as a "mythopoeic trilogy" (36). Concurrently, I examined the ongoing debate concerning Shelley's influences, as well as the early formation of his personality, as it pertains to the poems in question, and his fascination with …

Semiconductor Laser Device-Level Characteristics, Clement K. Law

Master's Theses

High-speed modulations of the semiconductor lasers are highly desirable in cost-effective optical communication systems.  Developing the experimental setups to extract the characteristics of the semiconductor lasers is vital to the future of the optical research projects.  In this thesis, integrated experimental setup designs have been developed to measure the characteristics of the Vertical Cavity Surface Emitting Laser (VCSEL), Distributed Feedback (DFB), and Fabry-Pérot (FP) lasers.  The measurements of the DC characteristics are optical power versus drive current (L-I) curves (DFB, VCSEL) and optical spectra (FP, DFB, VCSEL).  In addition, the high-speed optical detection measurement of the optoelectronic frequency responses for …

A Computational Study Of Engine Deflection Using A Circulation Control Wing, Bryan Holly Blessing

Master's Theses

In the past, research into Short Takeoff and Landing aircraft has led to the investigation of the coupling of a Circulation Control Wing and Upper Surface Blowing engine. The Circulation Control Wing entrains the flow of the engine to be deflected downward such that a component of the thrust is now in the vertical direction. The unfortunate consequence of the Upper Surface Blowing engine is the poor cruise performance due to scrub drag. Cal Poly's research into a Cruise Efficient Short Takeoff and Landing Aircraft offers a solution by pylon mounting over the wing engines. Analysis shows that the engine …

High-Frame-Rate Oil Film Interferometry, Jonathan Charles White

Master's Theses

High-Frame-Rate Oil Film Interferometry

Jonathan Charles White

This thesis presents the design and implementation of a high-frame-rate oil film interferometry technique (HOFI) used to directly measure skin friction in time dependent flows. Experiments were performed to determine the ability of a high-speed camera to capture oil film interferometry images. HOFI was found to be able to capture these interferometry images at frequencies up to 10⁵ Hz. Steady laminar and turbulent flows were tested. Transient flows tested consisted of a wind tunnel ramping up in velocity and a laminar boundary layer which was intermittently tripped to turbulence by puffing air …

The Effect Of The Chemical Composition Of Low Salinity Water On The Growth, Development, And Survival Of Cultured Juvenile Blue Crabs, Dyan Patricia Gibson

Master's Theses

Cultured juvenile blue crabs ( Callinectes sapidus Rathbun) were held for up to 77 days and monitored for survival, growth and development in low salinity water containing various compositions of ions. ~rabs were isolated in separate containers and placed in thirty gallon aquaria containing 2ppt of ion solution. Temperature, ambient, humidity, and nitrite levels were monitored daily. Molts were measured to determine growth, and molt increments were recorded to determine rate of development. The first part of the study compared ratios of sodium chloride (NaCl) to commercial sea salt (SS) in five treatments: 100% NaCl, 100% SS, 25:75 NaCl/SS, 50:50 …

Applied Bayesian Networks, Steven David Spansel

Master's Theses

A Bayesian Network is a stochastic graphical model that can be used to maintain and propagate conditional probability tables among its nodes. Here, we use a Bayesian Network to model results from a numerical riverine model. We develop an discretization optimization algorithm that improves efficiency and concurrently increases the overall accuracy of the resulting network. We measure accuracy using a new prediction accuracy criteria that includes an a posteriori soft correction. Furthermore, we show that this accuracy quickly asymptotes and begins to show diminishing returns on large data sets.

A Study Of Processing-Structure-Property Correlations In Novel Inorganic Phosphate Glass/Polyamide 66 Hybrid Materials With Enhanced Benefits, Jin Katena

Master's Theses

A new class of inorganic glass/organic polymer hybrid materials has been developed recently by using ultra low T_g tin fluorophosphate glass (Pglass) to combine the advantages of classical polymer blends and composite materials without their disadvantages. One of the important advantages using Pglass is that desirable morphology and properties can be tailored because Pglass becomes liquid under processing conditions of the most plastic materials. Recent study found that polar thermoplastic polymers seem to have a good interaction with the Pglass. In this study, the Pglass was introduced into a commodity thermoplastic polymer matrix, polyamide 66 (PA66), using a conventional …

Modeling Saltmarsh Sparrow Distribution In Connecticut, Susan T. Meiman

Master's Theses

To develop a map that would predict where saltmarsh sparrows live and reproduce in Connecticut, I compared models to test a) whether field data or remote-sensing data most effectively characterized within-marsh conditions that relate to sparrow occurrence, and b) whether including landscape-level variables improved model fit.  The best sparrow presence model used a variable derived from raw spectral reflectance values associated with plots where sparrows did not occur, while the best nest presence model used a combination of vegetation structure descriptions.   A second nest model, built using high resolution remote sensing data that organized marsh characteristics into high and low …

Geomagnetic Compensation For Low-Cost Crash Avoidance Project, John C. Torres

Master's Theses

The goal of this work was to compensate for the effects of the Earth’s magnetic field in a vector field magnetic sensor.  The magnetic sensor is a part of a low-cost crash avoidance system by Stephane Roussel where the magnetic sensor was used to detect cars passing when it was mounted to a test vehicle.  However, the magnetic sensor’s output voltage varied when it changed orientation with respect to the Earth’s magnetic field.  This limited the previous work to only analyze detection rates when the test vehicle travelled a single heading.  Since one of the goals of this system is …

Investigation Of The Behavior Of Free-Standing Gabions In Seismic Regions, Amy Ransom

Master's Theses

This thesis investigates the behavior of free-standing gabion walls in areas of mild seismicity. To investigate this behavior, three walls of varying internal cable patterns were constructed at a quarter-scale. These walls were tested with a mass shaker, and mode shapes, tone extractions, and damping ratios were calculated. A modal analysis was conducted using design spectra created from a suite of seven earthquakes from countries bordering Kenya. The corresponding lateral forces to these spectral displacements were found, and the restoring eccentricities from the soil restoring force were backed out through a summation of moments. All analysis was experimentally done due …

Probabilistic Fault Displacement Hazard Analysis For Reverse Faults And Surface Rupture Scale Invariance, Zachary E. Ross

Master's Theses

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px 'Times New Roman'}

A methodology is presented for evaluating the potential surface fault displacement on reverse faults in a probabilistic manner. This methodology follows the procedures put forth for Probabilistic Fault Displacement Hazard Analysis (PFDHA). Empirical probability distributions that are central to performing a PFDHA are derived from field investigations of reverse faulting events. Statistical analyses are used to test previously assumed properties of scale invariance with respect to magnitude for normalized displacement. It is found that normalized displacement is statistically invariant with respect to magnitude and focal mechanism, allowing for the …

Optimization Of Point-Of-Use Water Treatment Device For Disaster Relief, Margaret June Herzog

Master's Theses

Point-of-use (POU) drinking water treatment is a common method of providing drinking water in disaster relief situations when critical water infrastructure is damaged. In these cases, POU treatment devices can be used to treat local water until relief organizations set up more permanent water provision methods. One such POU technology is PŪR^® Purifier of Water, a combined coagulation/flocculation and disinfection chemical treatment sachet produced by Procter & Gamble. PŪR^® has been shown to treat contaminated water to meet water quality standards and guidelines set by the U.S. EPA for water purifiers and by the World Health Organization and …
