Advances In Student Self-Authorship: A Program Evaluation Of The Community Standards Model, Klinton E. Hobbs
Advances In Student Self-Authorship: A Program Evaluation Of The Community Standards Model, Klinton E. Hobbs
Theses and Dissertations
Universities are increasingly applying student developmental theories in a variety of contexts in order to better understand students and to accomplish institutional educational objectives. Robert Kegan's constructive-developmental theory has been utilized in the creation of the Community Standards Model, a program designed for use in university residence halls. The purpose of the Model is to promote student development from Kegan's third order of consciousness, in which student identity is based on a fusion of their peers' expectations and ideas, to the fourth order of consciousness, in which one becomes the author of his or her own values, beliefs, and ideals. …
Poisoning And Sulfation On Vanadia Scr Catalyst, Xiaoyu Guo
Poisoning And Sulfation On Vanadia Scr Catalyst, Xiaoyu Guo
Theses and Dissertations
Deactivation of titania-supported vanadia commercial SCR catalysts exposed to flue gases from both coal and coal-biomass co-firing boilers were investigated. BET surface area and average pore diameter measurements on both fresh and exposed commercial catalyst samples indicated pore plugging occurred to exposed catalyst samples. ESEM analyses showed fouling on catalyst surface, and poison deposition on both catalyst surface and inner pores. Activity assessments of commercial monolith catalysts with various exposures (time and fuel type) indicated that catalyst deactivation involves fouling, pore plugging, and poisoning. Different mechanisms may dominate depending on exposure time, catalyst properties, and combustion environment. Better controlled lab-scale …
The Relationship Of Implicit Family Process Rules To Adolescent Presentation Of Psychological Systems, Ian David Feinauer
The Relationship Of Implicit Family Process Rules To Adolescent Presentation Of Psychological Systems, Ian David Feinauer
Theses and Dissertations
Implicit family process rules refer to unspoken rules about family beliefs and expectations about communication, closeness, and organization and are an important dimension of family functioning that may have a powerful influence over adolescent psychological well being. This study focused on the relationship between implicit family process rules and adolescent psychological symptoms such as: Hostility, interpersonal sensitivity, depression, anxiety, and somatization. It was hypothesized that more facilitative implicit family process rules would be related to fewer adolescent psychological symptoms. In addition, a model was created that included theexogenousindependent variables of family status, (defined as intact-marriage or non-intact), treatment status (whether …

Influence Of Age On Auditory Gating, Ginny Marissa Smith
Theses and Dissertations
This study utilized paired tones at 1000 Hz with a 500 ms interpair interval and a 10 s interstimulus interval to assess sensory gating. Forty-two participants, ranging from 3-72 years of age were used to observe maturational changes in amplitude, latency, and suppression ratios of the P50 waveform. Previous research has shown that in normal adults the amplitude in response to the second of the paired tones is significantly suppressed compared to the amplitude in response to the first tone. The current study showed amplitude decreased with age to middle adulthood, where it increased slightly to later adulthood. Latencies decreased …
The Use Of Viewing Time Of Non-Erotic Visual Stimuli To Differentiate Between Frequent Pornography Users And Infrequent Users, Brian James Sneed
The Use Of Viewing Time Of Non-Erotic Visual Stimuli To Differentiate Between Frequent Pornography Users And Infrequent Users, Brian James Sneed
Theses and Dissertations
The purpose of this study was to determine whether a measure of viewing time that uses non-erotic visual stimuli can differentiate between frequent users and infrequent users of pornography. Thirty-six male participants were classified as infrequent pornography users and 37 as frequent users. Participants completed a questionnaire and were asked to rate a variety of images, both male and female of varying ages, on their sexual attractiveness. Individuals were timed as to how long they looked at each image. The groups were then compared based upon their viewing time of several categories. No statistically significant differences were detected. The temporal …
Fabrication Of Polymeric Microfluidic Devices For Protein Analysis, Jikun Liu
Fabrication Of Polymeric Microfluidic Devices For Protein Analysis, Jikun Liu
Theses and Dissertations
2-Bromoisobutyryl bromide was immobilized on poly(methyl methacrylate) (PMMA) substrates activated using an oxygen plasma. Atom-transfer radical polymerization was then performed to graft poly(ethylene glycol) (PEG) on the PMMA surface. PMMA micro capillary electrophoresis (µCE) devices made with the covalently modified surfaces exhibited substantially reduced electroosmotic flow and nonspecific adsorption of proteins. Both column efficiency and migration time reproducibility were one order of magnitude better with derivatized PMMA µCE devices compared to untreated versions. Fast, reproducible, and efficient separations of proteins and peptides were demonstrated using the PEG-grafted PMMA µCE chips. All analyses were completed in less than 60 seconds, and …
Mechanisms Of The Wurtzite To Rock Salt Phase Transitions In Galium Nitride, Jesse Z. Gunter
Mechanisms Of The Wurtzite To Rock Salt Phase Transitions In Galium Nitride, Jesse Z. Gunter
Theses and Dissertations
We studied the wurtzite to rock salt phase transition in gallium nitride ( GaN ). Using the mapping algorithm of COMSUBS we found 435 possible mechanisms for this transition. We then used FIREBALL to do density functional theory calculations and found enthalpy barrier heights for the transition pathway. We used this to determine the mechanisms that are the most favorable for GaN. The most favorable mechanisms for GaN are those that break no bonds during the phase transition. The bond-preserving mechanisms involve bilayer sliding of (010) hexagonal plane in the plus or minus [100] hexagonal direction.

The practice of counseling and psychotherapy is influenced by a number of ideologies, models, and paradigms. Among these, the medical model's influence is particularly salient. The ideology of the medical field pervades the theory, research, and practice of psychology and its influence deserves close examination. The few studies in this area that have been conducted are descriptive and basic in nature. The present study aimed to contribute richness and depth to conversations about medical model influence. By interviewing Counseling Psychology training directors and applying a qualitative analysis, this study provided the following themes that characterize views of the medical model's …
Compliant Mechanism Suspensions, Timothy Melvin Allred
Compliant Mechanism Suspensions, Timothy Melvin Allred
Theses and Dissertations
This thesis has explored the use of compliant mechanisms in vehicle suspension systems, specifically where a compliant mechanism acts as part of the wheel locating mechanism and as the energy storage element. A compliant mechanism has the potential of reducing part count, joints, and manufacturing and assembly costs of a suspension system. Fatigue failure has been found to be a limiting design constraint which competes with space and weight constraints. Controlling wheel motion in response to control forces has also been shown to be an important functional requirement for a compliant suspension system. Vehicle applications that are best suited for …

Minimum Spanning Tree Pose Estimation, Parris K. Egbert, Kevin L. Steele
Minimum Spanning Tree Pose Estimation, Parris K. Egbert, Kevin L. Steele
Faculty Publications
The extrinsic camera parameters from video stream images can be accurately estimated by tracking features through the image sequence and using these features to compute parameter estimates. The poses for long video sequences have been estimated in this manner. However, the poses of large sets of still images cannot be estimated using the same strategy because wide-baseline correspondences are not as robust as narrow-baseline feature tracks. Moreover, video pose estimation requires a linear or hierarchically-linear ordering on the images to be calibrated, reducing the image matches to the neighboring video frames. We propose a novel generalization to the linear ordering …

Histogram Matching For Camera Pose Neighbor Selection, Parris K. Egbert, Bryan S. Morse, Kevin L. Steele
Histogram Matching For Camera Pose Neighbor Selection, Parris K. Egbert, Bryan S. Morse, Kevin L. Steele
Faculty Publications
A prerequisite to calibrated camera pose estimation is the construction of a camera neighborhood adjacency graph, a connected graph defining the pose neighbors of the camera set. Pose neighbors to a camera C are images containing sufficient overlap in image content with the image from C that they can be used to correctly estimate the pose of C using structure-from-motion techniques. In a video stream, the camera neighborhood adjacency graph is often a simple connected path; frame poses are only estimated relative to their immediate neighbors. We propose a novel method to build more complex camera adjacency graphs that are …
Image Vectorization, Brian L. Price
Image Vectorization, Brian L. Price
Theses and Dissertations
We present a new technique for creating an editable vector graphic from an object in a raster image. Object selection is performed interactively in subsecond time by calling graph cut with each mouse movement. A renderable mesh is then computed automatically for the selected object and each of its (sub)objects by (1) generating a coarse object mesh; (2) performing recursive graph cut segmentation and hierarchical ordering of subobjects; (3) applying error-driven mesh refinement to each (sub)object. The result is a fully layered object hierarchy that facilitates object-level editing without leaving holes. Object-based vectorization compares favorably with current approaches in the …
Development And Comparison Of Highly Directional Loudspeakers, Gordon Robert Dix
Development And Comparison Of Highly Directional Loudspeakers, Gordon Robert Dix
Theses and Dissertations
Highly directive loudspeakers have long been important tools for sound system designers, experimental acousticians, and many other professionals in the audio industry. They allow sound engineers to more easily manipulate the radiation pattern of their loudspeakers to accommodate the purpose of the venue. Many commercially available products, while exhibiting good directivity at mid and high frequencies, generally lack control in the low frequency range. A new method for controlling the radiation pattern of a loudspeaker at low frequencies has been developed and modeled extensively. Prototypes have been built and tested in an anechoic chamber. Results from computer modeling and experimental …
Internalized Shame As A Moderating Variable For Inhibited Sexual Difficulties In Adult Women Resulting From Childhood Sexual Abuse, Kristine Robinson
Internalized Shame As A Moderating Variable For Inhibited Sexual Difficulties In Adult Women Resulting From Childhood Sexual Abuse, Kristine Robinson
Theses and Dissertations
An adult female sample of childhood sexual abuse survivors (N=467) were surveyed to determine whether internalized shame moderated the effects of sexual inhibited difficulties. Other variables such as severity, duration, and frequency of sexual abuse, as well as whether physical abuse was also part of their experience, were examined to determine their role in later sexual inhibition. It was predicted that there would be a significant positive relationship between 1) Scores on variables of physical abuse, severity of abuse, frequency of abuse, duration of abuse, identity of the perpetrator and scores on the variable of inhibited sexual difficulties; 2) Scores …
Temporal Data Mining In A Dynamic Feature Space, Brent K. Wenerstrom
Temporal Data Mining In A Dynamic Feature Space, Brent K. Wenerstrom
Theses and Dissertations
Many interesting real-world applications for temporal data mining are hindered by concept drift. One particular form of concept drift is characterized by changes to the underlying feature space. Seemingly little has been done to address this issue. This thesis presents FAE, an incremental ensemble approach to mining data subject to concept drift. FAE achieves better accuracies over four large datasets when compared with a similar incremental learning algorithm.
Direct Observation Of Laser Filamentation In High-Order Harmonic Generation, John Charles Painter
Direct Observation Of Laser Filamentation In High-Order Harmonic Generation, John Charles Painter
Theses and Dissertations
We investigate the spatial evolution of an intense laser pulse as it generates high-order harmonics in a long gas cell, filled with 80 torr of helium. A thin foil separates the gas-filled region of the cell from a subsequent evacuated region. The exit plane of the gas cell can be scanned along the laser axis so that the evolution of the laser throughout the focus can be observed (full scanning range of 9 cm). We constructed an apparatus that images the laser radial energy profile as it exits the cell. The high harmonics, odd orders ranging from 45 to 91, …
Food Shelf Life: Estimation And Experimental Design, Ross Allen Andrew Larsen
Food Shelf Life: Estimation And Experimental Design, Ross Allen Andrew Larsen
Theses and Dissertations
Shelf life is a parameter of the lifetime distribution of a food product, usually the time until a specified proportion (1-50%) of the product has spoiled according to taste. The data used to estimate shelf life typically come from a planned experiment with sampled food items observed at specified times. The observation times are usually selected adaptively using ‘staggered sampling.’ Ad-hoc methods based on linear regression have been recommended to estimate shelf life. However, other methods based on maximizing a likelihood (MLE) have been proposed, studied, and used. Both methods assume the Weibull distribution. The observed lifetimes in shelf life …

The purpose of this research was to investigate the effects of reclaimed asphalt pavement (RAP) content and cement content on the strength and durability of recycled aggregate base materials. Specifically, the unconfined compressive strength (UCS) and final dielectric value in the Tube Suction Test (TST) were measured in a full-factorial experimental design including five RAP contents, five cement contents, and three replicate specimens of each possible treatment. Specimen mixtures consisted of 0, 25, 50, 75, or 100 percent RAP and 0.0, 0.5, 1.0, 1.5, or 2.0 percent Type I/II Portland cement. Both the RAP and base materials were sampled from …
A Study Of Model Integration In Conjunction With The Extensible Model Definition Format, Melanie A. Fife
A Study Of Model Integration In Conjunction With The Extensible Model Definition Format, Melanie A. Fife
Theses and Dissertations
A considerable amount of research has been done to connect or integrate separate numerical models. The Environmental Modeling Research Laboratory (EMRL) has developed a generic file format, the eXtensible Model Data Format (XMDF). One of the objectives of the XMDF project is to facilitate the spatial interpolation and data-sharing necessary when linking models. The objective of this research is to investigate how model linking capabilities can be added to the XMDF by defining a Model Linkage Object (MLO) that is compatible with current model linking frameworks. A potential design for an MLO is defined in this thesis after a detailed …
Trust Negotiation For Open Database Access Control, Paul A. Porter
Trust Negotiation For Open Database Access Control, Paul A. Porter
Theses and Dissertations
Hippocratic databases are designed to protect the privacy of the individuals whose personal information they contain. This thesis presents a model for providing and enforcing access control in an open Hippocratic database system. Previously unknown individuals can gain access to information in the database by authenticating to roles through trust negotiation. Allowing qualified strangers to access the database increases the usefulness of the system without compromising privacy. This thesis presents the design and implementation of two methods for filtering information from database queries. First, we extend a query modification method for use in an open database system. Second, we introduce …
Delimitating Species Boundaries Within The Liomys Pictus- Spectabilis Complex (Rodentia: Heteromyidae), Victoria L. Vance
Delimitating Species Boundaries Within The Liomys Pictus- Spectabilis Complex (Rodentia: Heteromyidae), Victoria L. Vance
Theses and Dissertations
Previous studies based on morphological, allozymic and mitochondrial sequence data have indicated that Liomys pictus is paraplyletic relative to L. spectabilis. The purpose of this study was to determine the species boundaries that exist within this complex. I estimated phylogenetic relationships within this complex using sequence data from 1,140 bp of the mitochondrial DNA cytochrome b gene and two nuclear introns from engrailed protein (190 bp) and myosin heavy chain (254 bp) genes for approximately 712 individuals representing 82 localities across the range of L. pictus and L. spectabilis. Maximum parsimony, maximum likelihood, and Bayesian analyses suggest that there are …
