Student Teacher Knowledge And Its Impact On Task Design, Tenille Cannon Jul 2008

Student Teacher Knowledge And Its Impact On Task Design, Tenille Cannon

Theses and Dissertations

This study investigated how student teachers used their mathematical knowledge for teaching and pedagogical knowledge to design and modify mathematical tasks. It also examined the relationship between teacher knowledge and the cognitive demands of a task. The study relied heavily on the framework in Hill, Ball, and Shilling (2008), which describes the different domains of knowledge in mathematical knowledge for teaching, and the framework on the cognitive demands of mathematical tasks in Stein, Smith, Henningsen, and Silver (2000). Results of the study indicated that the student teachers used their common content knowledge when they lacked sufficient knowledge in other domains, …

Using Live Sequence Chart Specifications For Formal Verification, Rahul Kumar Jul 2008

Using Live Sequence Chart Specifications For Formal Verification, Rahul Kumar

Theses and Dissertations

Formal methods play an important part in the development as well as testing stages of software and hardware systems. A significant and often overlooked part of the process is the development of specifications and correctness requirements for the system under test. Traditionally, English has been used as the specification language, which has resulted in verbose and difficult to use specification documents that are usually abandoned during product development. This research focuses on investigating the use of Live Sequence Charts (LSCs), a graphical and intuitive language directly suited for expressing communication behaviors of a system as the specification language for a …

Boot Camp For The Psyche: Inoculative Nonfiction And Pre-Memory Structures As Preemptive Trauma Mediation In Fiction And Film, Jacob Michael Hodgen Jul 2008

Boot Camp For The Psyche: Inoculative Nonfiction And Pre-Memory Structures As Preemptive Trauma Mediation In Fiction And Film, Jacob Michael Hodgen

Theses and Dissertations

While some theorists have hinted at various social functions served by the gothic genre—such as providing an outlet for grief, anxiety, and violence in their various forms—recent research within the last few decades into sociology, military science, and trauma studies supplies compelling new ways of rereading the horror genre. In addition to providing an outlet for grief, anxiety, and violence in their various forms, horror media can now be read as a preemptive measure in an effort to mediate the immediate and long-term effects of the trauma and horror faced by humanity. I argue that in much the same way …

Complete Tropical Bezout's Theorem And Intersection Theory In The Tropical Projective Plane, Gretchen Rimmasch Jul 2008

Complete Tropical Bezout's Theorem And Intersection Theory In The Tropical Projective Plane, Gretchen Rimmasch

Theses and Dissertations

In this dissertation we prove a version of the tropical Bezout's theorem which is applicable to all tropical projective plane curves. There is a version of tropical Bezout's theorem presented in other works which applies in special cases, but we provide a proof of the theorem for all tropical projective plane curves. We provide several different definitions of intersection multiplicity and show that they all agree. Finally, we will use a tropical resultant to determine the intersection multiplicity of points of intersection at infinite distance. Using these new definitions of intersection multiplicity we prove the complete tropical Bezout's theorem.

The Effect Of A Pseudopalate On Voiceless Obstruent Production: A Spectral Evaluation Of Adaptation, Karie Lindsay Dean Jul 2008

The Effect Of A Pseudopalate On Voiceless Obstruent Production: A Spectral Evaluation Of Adaptation, Karie Lindsay Dean

Theses and Dissertations

Many studies in speech communication have provided valuable findings concerning the kinematic nature of speech articulation. This type of research often involves introducing an oral device to the vocal tract such as lingual pellets, magnets, and different forms of pseudopalates to track the movement and placement of the articulators. This study examined the effect of an electropalatography (EPG) pseudopalate on the production of five voiceless obstruents (/p, t, k, s/ and /sh/). Acoustic recordings from 20 adult speakers with typical speech production were made during three different speaking conditions: prior to pseudopalate placement, immediately after placement, and following 20 minutes …

Voltaire: From Sacrificial To Judicial System In The Play The Orphan Of China, Huichun Fang Jul 2008

Voltaire: From Sacrificial To Judicial System In The Play The Orphan Of China, Huichun Fang

Theses and Dissertations

Voltaire began his career in literature by writing for the theater. One of his plays, The Orphan of China, was an adaptation of a Chinese play, The Orphan of the Mansion Tchao. Many critics contend that in this play Voltaire is: 1. Propagating the spirit of the Enlightenment to the Europeans via his representation of the Chinese; 2. Refuting Rousseau because he condemns civilization as the source of men's suffering and pain; and 3. Lacking in understanding of Chinese history during the Mongolian invasion. This thesis will argue that critics have not examined the essential philosophical theory in The Orphan …

Non-Pedophilic Heterosexual Male Response To Affinity 2.0, Charles D. Crosby Jul 2008

Non-Pedophilic Heterosexual Male Response To Affinity 2.0, Charles D. Crosby

Theses and Dissertations

Given that the Affinity 2.0 is a largely untested instrument that purports to measure sexual attraction, it was unknown whether or not the instrument is temporally stable and would provide a characteristic response curve for normal heterosexual male sexual interest. This study examined the Affinity 2.0, a newly standardized viewing time (VT) instrument that purports to measure sexual interest. More specifically, the Affinity 2.0 was examined in regard to its temporal stability and ability to generate a characteristic curve for non-pedophilic, exclusively heterosexual male interests. This examination was carried out by administering the Affinity 2.0 twice on a sample of …

Males' Ipsative Score Distortion On Affinity 2.0, Jeffrey Brian Madsen Jul 2008

Males' Ipsative Score Distortion On Affinity 2.0, Jeffrey Brian Madsen

Theses and Dissertations

This study investigated the frequency of distortion that occurs when raw score patterns of Affinity 2.0, a viewing time measure designed to assess sexual interest, are converted to ipsative scores. Eighty-eight percent of a sample of ninety-nine non-pedophilic, exclusively heterosexual males' profiles sustained some degree of distortion. The study also applied Brown's (2005) approach to predicting distortion with this sample of males' responses. Brown's techniques were largely ineffective in predicting males' distortion scores.

Ion Permeation Through Membrane Channels: Molecular Dynamics Simulations Studies, Morad Mustafa Jul 2008

Ion Permeation Through Membrane Channels: Molecular Dynamics Simulations Studies, Morad Mustafa

Theses and Dissertations

Molecular dynamics simulation was used to study ion permeation through different membrane proteins embedded in a lipid bilayer (DMPC) with different saline solutions. The potential of mean force (PMF) for ion transport was obtained by umbrella sampling simulations. A revised MacKerell force field for tryptophan residues was studied using gramicidin A (gA) channel as a test model. The revised force field contribution to the Na+ PMF was consonant with the prediction from the experimental results, but in stark contrast to the prediction of the CHARMM force field, version 22, for the tryptophan side-chain. A new grid-based correction map algorithm by …

Psychoeducational Dissemination Across Distance: The Viability Of Telehealth With The Deaf Population, Jaime A. B. Wilson Jul 2008

Psychoeducational Dissemination Across Distance: The Viability Of Telehealth With The Deaf Population, Jaime A. B. Wilson

Theses and Dissertations

Within the deaf population, an extreme mental health professional shortage exists that may be alleviated with videoconferencing technology – also known as telehealth. Moreover, much needed mental health education within the deaf population remains largely inaccessible. Researchers have forewarned that the deaf population may remain underserved if significant changes do not take place with traditional service delivery methods. The goal of this study was to evaluate the efficacy of telehealth in teaching psychoeducational objectives, with special emphasis given to its application to the deaf population. The results of this study indicate that telehealth can be considered to be an efficacious …

Death In The Royal Family: Victorian Funeral Sermon Techniques In Tennyson's National Poetry, Daniel W. Newton Jul 2008

Death In The Royal Family: Victorian Funeral Sermon Techniques In Tennyson's National Poetry, Daniel W. Newton

Theses and Dissertations

Mourning rituals and memorial aesthetics played an integral role in Victorian England. Queen Victoria's poet laureate, Alfred Lord Tennyson, confronted death on a literary level. His national elegiac poetry — addressed to Victoria — is illuminated when read as a funeral sermon. By drawing out the funeral sermon techniques Tennyson incorporates, we see that he assumes a role as religious mediator to counsel and comfort Victoria in her grief. Tennyson's funeral sermon message alters quite distinctively from Albert's death in 1861, to the death of the Duke of Clarence in 1892, where he makes a final effort to restore the …

Recognizing The Need To Dissemble Emotions In Hypothetical Social Scenarios: Differences In Children With Language Impairment, Emily Rowberry Jones Jul 2008

Recognizing The Need To Dissemble Emotions In Hypothetical Social Scenarios: Differences In Children With Language Impairment, Emily Rowberry Jones

Theses and Dissertations

This study investigated the ability of children with LI to recognize the need to dissemble emotions. Participants included 22 children with LI and 22 typically developing peers, ages 7;1 to 11;0 years. Children were presented with 10 hypothetical social scenarios in which the main character experienced an emotion which should be dissembled for social purposes. The participant's responses were categorized as dissemblance or display. Children with LI reported that they would hide the experienced emotion significantly less often than their typical peers. Children in both groups reported higher levels of dissemblance when asked what their parents would want them to …

Competitive Exclusion Of Cyanobacterial Species In The Great Salt Lake, Hillary Christine Roney Jul 2008

Competitive Exclusion Of Cyanobacterial Species In The Great Salt Lake, Hillary Christine Roney

Theses and Dissertations

Under Gause's principle two species cannot indefinitely occupy the same niche. The north and south arms of Great Salt Lake are separated by a rail causeway, resulting in salinity differences and color variation between the arms. Farmington Bay is also separated from the south arm by a vehicular causeway to Antelope Island. These causeways allow examination of competitive exclusion of cyanobacteria in the hypersaline environment of the Great Salt Lake. Cyanobacterial distributions partially map salinity, with Aphanothece halophytica proliferating in the north arm, and Nodularia spumigena in the south arm. I hypothesized that cyanobacterial species abundant north of the railway …

Early Dynamics Of Ultracold Neutral Plasmas, Adam W. Denning Jul 2008

Early Dynamics Of Ultracold Neutral Plasmas, Adam W. Denning

Theses and Dissertations

We report new studies on the early-time dynamics of ultracold neutral plasmas. We use fluorescence spectroscopy to probe plasma dynamics on the nanosecond time scale. We determine the rms ion velocity during the initial plasma period. The initial ion acceleration is found as the time derivative of the ion velocity. We compare to a theoretical model. The experimental results agree with the model at low plasma densities. However, the ion acceleration is a factor of ten lower than the model at higher densities. The cause of this discrepancy is currently unknown.

Adapting Adtrees For Improved Performance On Large Datasets With High Arity Features, Robert D. Van Dam Jul 2008

Adapting Adtrees For Improved Performance On Large Datasets With High Arity Features, Robert D. Van Dam

Theses and Dissertations

The ADtree, a data structure useful for caching sufficient statistics, has been successfully adapted to grow lazily when memory is limited and to update sequentially with an incrementally updated dataset. However, even these modified forms of the ADtree still exhibit inefficiencies in terms of both space usage and query time, particularly on datasets with very high dimensionality and with high arity features. We propose five modifications to the ADtree, each of which can be used to improve size and query time under specific types of datasets and features. These modifications also provide an increased ability to precisely control how an …

The Rhetoric Of Violence, James Christiansen Gunter Jul 2008

The Rhetoric Of Violence, James Christiansen Gunter

Theses and Dissertations

This thesis seeks to understand how we read and understand the use of depictions of violence by examining its rhetorical presentation. Although the media gives us a mixed understanding of the way that experiencing violence secondarily (that is, through all types of media) affects us, scholarship in this area has proved clear connections between viewing/experiencing depictions of violence and raised levels of aggression. On the other hand, there is a clear difference between gratuitous depictions of violence and socially useful depictions of violence (i.e., the difference between a slasher movie and a holocaust movie) that that area of scholarship does …

Using A Chelator-Buffered Nutrient System To Study Phosphorus, Manganese And Zinc Interactions In Russet Burbank Potato, Steven A. Barben Jul 2008

Using A Chelator-Buffered Nutrient System To Study Phosphorus, Manganese And Zinc Interactions In Russet Burbank Potato, Steven A. Barben

Theses and Dissertations

Potato production requires high phosphorus (P) application with potential negative environmental or nutritional consequences for potato as well as for subsequent crops. Impacts of high available P on yield and plant nutrition of species in potato cropping rotations are inadequately understood, and could result in antagonistic interactions with cationic micronutrients such as zinc (Zn) and manganese (Mn). Three hydroponic experiments were conducted with Russet Burbank potato to elucidate P and Zn relationships and associated interactions with other nutrients. In the first experiment, P solution concentration was constant at 256 µM while Zn concentration varied: 0.1, 2, 6, 18, 54, 162 …

Towards A New Currency Of Economic Criticism, Jason G. Douglas Jul 2008

Towards A New Currency Of Economic Criticism, Jason G. Douglas

Theses and Dissertations

“The Purloined Letter,” Edgar Allan Poe's third and final tale featuring the detective Dupin, has evoked a long history of critical response. Criticism has tended to read the text for its role in the development of detective fiction and as illustrative of various theoretical positions. However, the implications of the “The Purloined Letter,” as a tale of ratiocination, has largely been left unexplored. “The Purloined Letter” explores logical processes of value and exchange, particularly economic exchange, in a manner very similar to what Charles Sanders Peirce will call pragmatism several decades later. Dupin's deductive methods and Peirce's abductive logic express …

Choose Your Words: Refining What Counts As Mathematical Discourse In Students' Negotiation Of Meaning For Rate Of Change Of Volume, Christine Johnson Jul 2008

Choose Your Words: Refining What Counts As Mathematical Discourse In Students' Negotiation Of Meaning For Rate Of Change Of Volume, Christine Johnson

Theses and Dissertations

The purpose of this study is to describe how university honors calculus students negotiate meaning and language for conceptually important ideas through mathematical discourse. Mathematical discourse has been recognized as an important topic by mathematics education researchers of various theoretical perspectives. This study is written from a perspective that merges symbolic interactionism (Blumer, 1969) with personal agency (Walter & Gerson, 2007) to assert that human choice reflects, but is not determined by, meanings that are primarily developed through social interaction. The process of negotiation of meaning is identified, described, and analyzed in the discourse of four students and their professor …

Analog Feedback Control Of An Active Sound Transmission Control Module, Jason Derek Sagers Jul 2008

Analog Feedback Control Of An Active Sound Transmission Control Module, Jason Derek Sagers

Theses and Dissertations

This thesis provides analytical and experimental proof-of-concept for a new feedback-controlled sound transmission control module for use in an active segmented partition (ASP) array. The objective of such a module is to provide high transmission loss down to low audible frequencies while minimizing the overall mass of the module. This objective is accomplished in the new module by using actively controlled panels in conjunction with analog feedback controllers. The new module also overcomes two limitations that exist in current ASP modules: the inability to control broadband random-noise and the lack of bidirectional control through the module. Overcoming these limitations represents …
