Space Vessels

Description: The submarine and the spaceship fit in perfectly with the ideas of permanence and protection on which my work has been focusing. It is not coincidental that I have long been fascinated with the shapes and mechanisms of these vehicles. They are complex machines designed for a complex function; I find the precision of this to be appealing. I have used their shapes and mechanisms as design aspect in my thesis work. Also, in the studio, I have developed a type of Damascus steel bowl by modifying a … more

On the Relation between Stimulus Equivalence and Extension of Stimulus Function

Description: The purpose of this study was to examine the relation between stimulus equivalence (briefly, networks of relations among stimuli) and the extension of stimulus function (briefly, spread of effect across network) more closely than has been possible before. The traditional view of this relation suggests that equivalence classes mediate the extension of stimulus function and are, therefore, necessary for any extension to occur. This study used a preparation in which the conditional discriminations… more

Spaces of Compact Operators

Description: In this dissertation we study the structure of spaces of operators, especially the space of all compact operators between two Banach spaces X and Y. Work by Kalton, Emmanuele, Bator and Lewis on the space of compact and weakly compact operators motivates much of this paper. Let L(X,Y) be the Banach space of all bounded linear operators between Banach spaces X and Y, K(X,Y) be the space of all compact operators, and W(X,Y) be the space of all weakly compact operators. We study problems relate… more

Ethics Naturally: An Environmental Ethic Based on Naturalness

Description: In this thesis I attempt to base an environmental ethic on a quality called naturalness. I examine it in terms of quantification, namely, as to whether it can quantified? I then apply the concept to specific areas such as restoration and conservation to create an environmental ethic and to show how such an ethic would be beneficial in general, and especially to policy issues concerning the environment. The thesis consists of three chapters: (1) the definition of nature and natural by way of a h… more

Art or Craft?

Description: I chose to exhibit sculpture and classical style vessels together to encourage discussion about whether ceramics should be considered a fine art medium. I was interested in experimenting with different forms and textures in order to see which combination would captivate the viewing audience the longest. I found that massive textural sculptural forms held the attention of the viewer more so than did the classical smooth surfaced vessels.

Use of Fading Procedures and Positive Reinforcement to Increase Consumption of Non-Preferred Food in a Child with Autism

Description: Traditionally children with developmental disabilities who develop feeding issues can be at great risk for malnutrition. Failure to eat adequate amounts of food and/or insistence on eating a limited range of foods can be detrimental to a child's health and can lead to other behavioral difficulties. Feeding problems are difficult to treat because high levels of physical prompting can quickly create an aversion to eating as well as cause stress for both parents and children. Behavioral problems t… more

Culturing Vallisneria americana for Restoration Efforts

Description: Robust Vallisneria americana was cultured for restoration purposes. Preliminary studies, with various iron treatments, were conducted to ascertain the amount of phosphorous release into the water column from sediments. There was a significant difference in the amount of phosphorous released if commercial sediment was used with a low iron amendment or without an iron amendment. The second study consisted of planting V. americana on two different sediment types while supplying half of the pla… more

Preparation and characterization of praseodymium oxide films and powders.

Description: Nanocrystalline praseodymium oxide films have been successfully generated on stainless steel substrates. The electrochemical deposition was performed in the cathode compartment of a divided electrochemical cell with a regular three-electrode configuration. The green films obtained by electrodeposition were then annealed at high temperatures for 1-3 hours. X-ray diffraction revealed the fluorite structure of Pr6O11 and the crystallite size was calculated. X-ray photoelectron spectroscopy was emp… more

Instigating a Necessary Epiphany in Visual Message-Making for Design Educators and Future Communication Designers

Description: Man has used graphic signs and symbols to express a variety of thoughts and feelings since before the invention of writing; they have helped him to preserve the ideologies that have enabled him to articulate his conception of the world. Every culture in every historical era has invested the objects, animals and plants around it with a multitude of different psychological meanings to communicate its essential belief systems and social aspirations. In my document, I chose to shed light on the res… more

Professional Widow

Description: The focus of my graduate work was to figure my way through a variety of challenges and transitions I was going through as a graduate student and simply as a person finding my way through my education to discover who I am and who I want to become. Perhaps my themes didn't focus primarily on these events in a literal sense, but I think the transitions in my artwork have become obvious through my time spent at UNT and the variations on a theme I have dealt with. All of my work deals with love, att… more

The Unreadable Word

Description: This autobiographical problem in lieu of thesis explores the subject matter of the sculpture, revolving around the issues of dyslexia and literacy, and builds upon the idea of metaphor and its function in relationship to the sculpture. The four visual and conceptual elements that are emphasized are: (a) the juxtaposition and arrangement of elements and materials; (b) inability to open the books; (c) alteration of the text to make the words illegible, by creating words that are fuzzy or transpar… more

Wild Practices: Teaching the Value of Wildness

Description: The notion of wildness as a concept that is essentially intractable to definition has profound linguistic and ethical implications for wilderness preservation and environmental education. A survey of the ways in which wilderness value is expressed through language reveals much confusion and repression regarding our understanding of the autonomy of nature. By framing discussions of wilderness through fact-driven language games, the value of the wild autonomy in nature becomes ineffable. In remo… more

Order effects of variability-contingent and variability-independent point delivery: Effects on operant variability and target sequence acquisition.

Description: Previous research has shown that variability is a reinforceable dimension of operant behavior. Additionally, it has been demonstrated that learning is facilitated when variability in responding is high. In this research, variability was observed within an operant composed of any sequence of six left and right key presses. Variability was either a requirement for point delivery (VAR conditions) or points were delivered independent of variability (ANY conditions). Two groups of college undergradu… more

Intelligent Memory Manager: Towards improving the locality behavior of allocation-intensive applications.

Description: Dynamic memory management required by allocation-intensive (i.e., Object Oriented and linked data structured) applications has led to a large number of research trends. Memory performance due to the cache misses in these applications continues to lag in terms of execution cycles as ever increasing CPU-Memory speed gap continues to grow. Sophisticated prefetcing techniques, data relocations, and multithreaded architectures have tried to address memory latency. These techniques are not completely… more

Adherence/Diffusion Barrier Layers for Copper Metallization: Amorphous Carbon:Silicon Polymerized Films

Description: Semiconductor circuitry feature miniaturization continues in response to Moore 's Law pushing the limits of aluminum and forcing the transition to Cu due to its lower resistivity and electromigration. Copper diffuses into silicon dioxide under thermal and electrical stresses, requiring the use of barriers to inhibit diffusion, adding to the insulator thickness and delay time, or replacement of SiO2 with new insulator materials that can inhibit diffusion while enabling Cu wetting.

Within-session session changes in responding as a function of habituation vs. satiation.

Description: Behavior analysts refer to a decrease in response rate following repeated, contingent presentations of a reinforcing stimulus as a product of satiation. Other evidence suggests that these decreases may often be due to habituation to the sensory properties of the reinforcing stimulus. The investigation reported here sought to determine whether decreases in operant responding by 3 adults with developmental disabilities were due to satiation or habituation. During baseline, participants placed pok… more

Layered Double Hydroxides: Synthesis, Characterization, and Interaction of Mg-Al Systems with Intercalated Tetracyanonickelate(II)

Description: The square-planar tetracyanonickelate(II) anion was intercalated into 2:1 and 3:1 Mg-Al layered double hydroxide systems (LDHs). In the 2:1 material, the anion holds itself at an angle of about 30° to the layers, whereas in the 3:1 material it lies more or less parallel to the layers. This is confirmed by orientation effects in the infrared spectra of the intercalated materials and by X-ray diffraction (XRD) data. The measured basal spacings for the intercalated LDH hosts are approximately 1… more
