A Comparison Of Boltzmann And Gibbs Definitions Of Microcanonical Entropy For Small Systems, Randall B. Shirts Dec 2012

A Comparison Of Boltzmann And Gibbs Definitions Of Microcanonical Entropy For Small Systems, Randall B. Shirts

Faculty Publications

Two different definitions of entropy, S= klnW, in the microcanonical ensemble have been competing for over 100 years. The Boltzmann/Planck definition is that W is the number of states accessible to the system at its energy E (also called the surface entropy). The Gibbs/Hertz definition is that W is the number of states of the system up to the energy E (also called the volume entropy). These two definitions agree for large systems but differ by terms of order N-1 for small systems, where N is the number of particles in the system. For three analytical …

Teacher Nominations And The Identification Of Social, Emotional, And Behavioral Concerns In Adolescence, Stephanie Deverich Davis Dec 2012

Teacher Nominations And The Identification Of Social, Emotional, And Behavioral Concerns In Adolescence, Stephanie Deverich Davis

Theses and Dissertations

Emotional and Behavioral Disorders (EBD) directly influence learning, relationships, mood, and overall scholastic experiences. Research provides evidence that early intervention and prevention efforts can address the needs of students with EBD (Allen-DeBoer, Malmgren, & Glass, 2006; Cook, et al. 2008; Lien-Thorne & Kamps, 2005; Regan, Mastropieri, & Scruggs, 2005; Rivera, Al-Otiba, & Koorland, 2006), but in order to identify these at-risk youth, a screening system is needed to broadly consider Social, Emotional, and Behavioral Concerns (SEBC).This dissertation evaluated the alignment of a teacher nomination process (Teacher Nomination Form (TNF)) and a normative screener of EBD risk (BASC-2 Behavioral and Emotional …

Closing The Church University In 1894: Embracing Or Accommodating Secularized Education, Brian William Ricks Dec 2012

Closing The Church University In 1894: Embracing Or Accommodating Secularized Education, Brian William Ricks

Theses and Dissertations

The late 1800s have been noted as a major transitional period for the Church of Jesus Christ of Latter-day Saints. When the beleaguered pioneers first arrived in Utah they were isolated from the influence and expectations of the United States. During that time, leaders of the Church became influential in every aspect of life in Utah. By the end of the nineteenth century, however, the period of isolation had come to an end. Nationally, the social norms had changed and religion was expected to stay in the churches and out of politics. Church leaders were faced with serious questions regarding …

Noun Clauses In Clinical Child Language Samples, Christine Beate Scoville Dec 2012

Noun Clauses In Clinical Child Language Samples, Christine Beate Scoville

Theses and Dissertations

Noun clauses are grammatical constructions that are of relevance both to typical language development and impaired language development. These clauses have been part of published techniques for the clinical analysis of language samples, and computer software for the automated analysis of clinical language samples has attempted to identify noun clauses, with limited success. The present study examined the development and clinical use of noun clauses as well as the automated identification of these clauses. Two sets of language samples were examined. One set consisted of 10 children with specific language impairment (SLI) whose age ranged from 7;6 to 11;1 (years;months), …

Nouns And Verbs In The Tagalog Mental Lexicon, Linda Walton Dec 2012

Nouns And Verbs In The Tagalog Mental Lexicon, Linda Walton

Theses and Dissertations

The purpose of this research was to study grammatical categories in the Tagalog mental lexicon using lexical decision tasks. Some linguists question whether words in Tagalog can be classified as nouns and verbs (Foley, 1998; Kaufman, 2011) because most root words can be inflected for any grammatical function and because verbs cannot be used in their uninflected form. Previous studies with English and German (Kauschke and Stenneken 2008) have shown that participants respond differently to nouns and verbs in lexical decision tasks. These studies have also shown that participants respond differently to transitive and intransitive verbs in lexical decision tasks. …

Does Attachment To Parents Mediate The Relationship Between Couple Conflict And Adolescent Self-Regulation?, Lisa Tensmeyer Hansen Dec 2012

Does Attachment To Parents Mediate The Relationship Between Couple Conflict And Adolescent Self-Regulation?, Lisa Tensmeyer Hansen

Theses and Dissertations

Adolescent self-regulation follows a developmental trajectory over time with ups and downs during maturation. This paper uses growth curve analysis to look at change in self-regulation over time. Although self-regulation scores may increase during latency, adolescents differ in levels of self-regulation due to biological and socialization factors. In addition, exposure to couple conflict has been shown to affect levels of self-regulation. The current study examined the role of attachment to parents as a mediator between couple conflict and adolescent self-regulation outcomes, controlling for gender of child. Participants were 681 families with a child between the ages of 11 and 13 …

Measuring The Technical Difficulty In Reusing Open Educational Resources With The Alms Analysis Framework, Seth Michael Gurell Dec 2012

Measuring The Technical Difficulty In Reusing Open Educational Resources With The Alms Analysis Framework, Seth Michael Gurell

Theses and Dissertations

The Open Educational Resources (OER) movement was started roughly ten years old (Wiley & Gurell, 2009). Since that time thousands of resources have been produced. Though these resources have been used both for classroom development and for the autodidact, the development of OER was not without problems. Incompatibility between Creative Commons licenses has made revising and remixing two resources difficult, if not impossible (Linksvayer, 2006). Tools to help educators find appropriate educational resources have been necessary but are still nascent. Educators' perceived quality issues have also hampered adoption (Wiley & Gurell, 2009). The result is that resources were only being …

Structural Design Of Flexible Etfe Atrium Enclosures Using A Cable-Spring Support System, Ryan Paul Bessey Dec 2012

Structural Design Of Flexible Etfe Atrium Enclosures Using A Cable-Spring Support System, Ryan Paul Bessey

Theses and Dissertations

This research designed and analyzed an innovative structural support system for ETFE (ethylene tetrafluoroethylene) atrium roofs between buildings. A cable-spring system was conceived, which is much lighter and more flexible than arches, frames, trusses, and beams which usually support ETFE roofs. Flexibility was a desirable property because the displacements may vary significantly among the buildings supporting the ETFE atrium roof during wind and seismic loading. The springs in the cable-spring system allow large differential displacements without exerting large support reactions on the buildings. The flexibility of the cable-spring system was compared to the cable-strut system which is used to support …

"Une Transformation Profonde": Decay And Beauty In Cléo From 5 To 7, Susan J. Garver Dec 2012

"Une Transformation Profonde": Decay And Beauty In Cléo From 5 To 7, Susan J. Garver

Theses and Dissertations

Cléo from 5 to 7 is perhaps the most famous work of influential French filmmaker Agnès Varda, who is often called the "Grande Dame of the New Wave". The depth of symbolism, the richness of imagery, the beginnings of cinécriture (a Varda-ism describing cinema as a form of writing that uses all the tools available to a filmmaker, not just words), and the charm of the story have guaranteed Cléo's popularity with scholars and audiences alike. Current scholarship has tended to focus on a few aspects of Cléo, including her role as a flâneuse, the use of …

Cultural Thinning Of Native Sagebrush Stands To Increase Seed Yields, Kurt David Elder Dec 2012

Cultural Thinning Of Native Sagebrush Stands To Increase Seed Yields, Kurt David Elder

Theses and Dissertations

Wyoming big sagebrush (Artemisia tridentata Nutt.) is an important native shrub in the Great Basin because of its wide distribution where it dominates over 60 million ha and provides essential habitat and forage for many varied species. The hand collection of sagebrush seed often results in seed scarcity and the available seed quantities are at times inadequate to revegetate large areas that have been disturbed, resulting in a demand for sagebrush seed. Study locations were selected near Scipio and Sahara sand dunes of Utah, and treatments were 1-) control, no treatment applied area left undisturbed 2-) general chemical strip …

A Tree Theory Case Study In Steinernema, Camille Eileen Finlinson Porter Dec 2012

A Tree Theory Case Study In Steinernema, Camille Eileen Finlinson Porter

Theses and Dissertations

It is widely assumed that current phylogenetic methods are fairly accurate at recovering the evolutionary relationships among different species, but evaluating the relative success of this enterprise is a difficult task. This study addresses some fundamental questions associated with generating phylogenetic trees. The complete genomes of five species of Steinernema were sequenced and assembled. Genes were predicted in AUGUSTUS and orthologous genes were found from those data using OrthoMCL. I aligned 3890 genes in MAFFT and eliminated poorly aligned positions with GBlocks. I created individual trees for each gene as well as a supermatrix tree in PAUP*, using a closely …

Theatre History In The Secondary Drama Classroom And Beyond, Sandra Kay Millet Dec 2012

Theatre History In The Secondary Drama Classroom And Beyond, Sandra Kay Millet

Theses and Dissertations

Current Utah State Core Standards for Theatre require that theatre history be taught at levels II (Standard 3 Objective C), III (Standard 4 Objective D), and IV (Standard 4 Objectives A and D) of high school drama classes. However, a 2011 survey of Utah high school theatre teachers indicates that only 54% include theatre history as an "important" or "very important" part of their curriculum, while another 36% say they "touch on it." This thesis is designed to be a resource for secondary drama teachers in integrating theatre history pedagogy into their drama classes, in an engaging and performance-based manner …

Long-Term Depression Of Excitatory Inputs To Gabaergic Neurons In The Ventral Tegmental Area, Philip J. Sandoval Dec 2012

Long-Term Depression Of Excitatory Inputs To Gabaergic Neurons In The Ventral Tegmental Area, Philip J. Sandoval

Theses and Dissertations

Dopamine cells within the ventral tegmental area of the brain are involved in motivation and reward. Drugs of abuse target these dopamine cells altering their activity and plasticity resulting in addiction. While dopamine cell activity is primarily involved in addiction, the GABA neurons in the VTA have also been shown to have an indirect role. By decreasing the activity of the inhibitory GABA inputs onto dopamine neurons abusive drugs can indirectly increase dopamine cell activity resulting in addictive behaviors. However, although GABA neurons are important in the perception of reward, much less is known about how the excitatory inputs to …

Transcriptome And Methylation Analysis Of Gossypium Petal Tissue, Aditi Rambani Dec 2012

Transcriptome And Methylation Analysis Of Gossypium Petal Tissue, Aditi Rambani

Theses and Dissertations

Polyploidization instantly doubles all genome content by combining two genomes that have markedly different methylation and gene expression levels. This process may be accompanied by genetic and epigenetic changes in each genome. Sequencing of the transcriptome (RNA-seq) and the methylome (bisulfite treated libraries whole genome libraries) were used to measure gene expression and methylation levels of genic regions of allopolyploid cotton petals and petals of their diploid relatives. Many differentially expressed genes detected by RNA-seq were consistent with expression levels previously detected by microarrays. RNA-seq results also reconfirmed the presence of general polyploid gene expression trends like expression level dominance …

Transcriptome Analysis Of Drought Induced Stress In Chenopodium Quinoa, Joshua Arthur Raney Dec 2012

Transcriptome Analysis Of Drought Induced Stress In Chenopodium Quinoa, Joshua Arthur Raney

Theses and Dissertations

RNA-seq transcriptome analysis of Chenopodium quinoa at different water treatment levels was conducted in a greenhouse study using four water treatments (field capacity to drought) on a valley ecotype quinoa (variety Ingapirca) and an Altiplano Salares ecotype quinoa (variety Ollague). Physiological results support the earlier findings that the Salares ecotypes display greater tolerance to drought-like stress conditions than the valley ecotypes (as determined by growth rate, photosynthetic rate, stomatal conductance, and stem water potential). cDNA libraries from root tissue sample for each treatment x variety combination were sequenced using Illumina Hi-Seq technology in an RNA-seq experiment. De novo assembly of …

Characterization Of Sterile Tassel Silky Earl: A Homeotic B-Class Gene Involved In Specification Of Floral Organ Identity In Zea Mays, Steven Keith Williams Dec 2012

Characterization Of Sterile Tassel Silky Earl: A Homeotic B-Class Gene Involved In Specification Of Floral Organ Identity In Zea Mays, Steven Keith Williams

Theses and Dissertations

Specification of floral organ identity in angiosperm flowers is accomplished by the coordinated activity of A-, B-, C-, and E-class MADS-box genes. In the eudicots, B-class genes specify petal and stamen identity. This eudicot B-class function depends on the simultaneous expression of genes from two paralogous B-class lineages (the DEFICIENS/APETALA3 lineage and the GLOBOSA/PISTILLATA lineage). Proteins produced by genes from these two lineages interact as obligate heterodimers and together regulate the transcription of various downstream targets. These obligate heterodimers also positively regulate the transcription of the B-class genes themselves, thereby mediating a unique B-class autoregulatory feedback loop. There is compelling …
