How A Master Teacher Uses Questioning Within A Mathematical Discourse Community, Omel Angel Contreras Jul 2006

How A Master Teacher Uses Questioning Within A Mathematical Discourse Community, Omel Angel Contreras

Theses and Dissertations

Recent scholarly work in mathematics education has included a focus on learning mathematics with understanding (Hiebert & Carpenter, 1992; Hiebert et al., 1997; Fennema & Romberg, 1999; National Council of Teachers of Mathematics, 2000). Hiebert et al. (1997) discussed two processes that they suggested increase understanding and that are central to this study: reflection and communication. Learning mathematics with understanding requires that the students create a deeper knowledge of mathematics through reflection and communication. The environment in which such learning can take place must include patterns of behavior, known as social norms that promote deeper thinking. When the social norms …

Sequence Analysis Of Pmel17 As Candidate Gene For Causing Rat-Tail Syndrome In Cattle, Benjamin C. Hecht Jul 2006

Sequence Analysis Of Pmel17 As Candidate Gene For Causing Rat-Tail Syndrome In Cattle, Benjamin C. Hecht

Theses and Dissertations

Congenital hypotrichosis in cattle is commonly referred to as "rat-tail" syndrome and is characterized by a dilution of black coat color and morphological changes to the hair shaft and tail switch. Two loci are involved in the inheritance of the rat-tail phenotype, the "extension locus" (MC1R) and an unknown locus. In order to express the rat-tail phenotype the animal must inherit at least one black allele at MC1R and be heterozygous at the unknown locus. The rat-tail locus was previously mapped to an 8.7 cM region of Bos Taurus autosome (BTA) 5. Pmel17 is known to be involved in the …

The Memory Of The Body And Other Stories, Ryan Craig Shoemaker Jul 2006

The Memory Of The Body And Other Stories, Ryan Craig Shoemaker

Theses and Dissertations

This thesis is a collection of short stories written over the years 2002 to 2006. The short story is a genre that requires brevity. The short story writer, instead of treating the totality of human life, is forever, as Frank O'Connor suggests, selecting the point at which he can approach it. For this reason, unlike the novel, there is very little dallying in the short story. The short story writer, as the form requires, must make his world believable and coherent with only a minimum of words. Based on the experience of the actual author, the short story, like all …

Second Graders' Solution Strategies And Understanding Of A Combination Problem, Tiffany Marie Hessing Jul 2006

Second Graders' Solution Strategies And Understanding Of A Combination Problem, Tiffany Marie Hessing

Theses and Dissertations

I inquire about second graders' capabilities of developing solution strategies and the original variety of strategies they bring forth while solving a combination problem. Based on analysis of the data presented in this paper, students developed five different general strategies. After analyzing what the second grade students were capable of developing, we can conclude that young children are capable of developing powerful systematic strategies grounded in their personal experiences. This research shows that even when the teacher does not foster personal agency, children will still exercise agency. The social interactions in the classroom helped students learn to propose mathematical ideas, …

"Th' Offense Pardons Itself": Sex And The Church In Othello And Measure For Measure, Jeffrey Wayne Windsor Jul 2006

"Th' Offense Pardons Itself": Sex And The Church In Othello And Measure For Measure, Jeffrey Wayne Windsor

Theses and Dissertations

In 1604, James had newly ascended to the throne and England was now part of Great Britain. The Puritans-largely silenced during Elizabeth's reign-began again to assert political influence and call for reformation to both the state and the church. This is the context in which Shakespeare wrote Othello and Measure for Measure. In both plays, the role of the government in Cyprus or Vienna hinges upon the passions of a single authority figure. Both Angelo and Othello cause political unrest because they mismanage sexuality. In the case of Othello, his unfounded sexual jealousy leads to the death of Desdemona, Emilia, …

Proud To Send Those Parachutes Off: Central Utah's Rosies During World War Ii, Amanda Midgley Borneman

Theses and Dissertations

World War II affected individuals across the nation, both on the home front and on the front lines. Manti, Utah received a new industry, a parachute plant, in connection with the war. Hundreds of women from Sanpete County and neighboring counties were employed through the duration of the war in everything from sewing and inspection to supervision of production. Some of the women utilized childcare facilities, some formed a union, and many found community and familial support. For many of them, this wartime wage work provided a welcomed alternative to the work usually found in rural areas, such as farm …

Telling History Through The Stories Of Women: Julia Alvarez's In The Time Of The Butterflies And In The Name Of Salomé, Nicole Marie Carlson Jul 2006

Telling History Through The Stories Of Women: Julia Alvarez's In The Time Of The Butterflies And In The Name Of Salomé, Nicole Marie Carlson

Theses and Dissertations

My thesis discusses the ways in which Julia Alvarez's In the Time of the Butterflies (1994) and In the Name of Salomé (2000) are revolutionary texts contesting traditional, male dominated history and redirecting historical and communal foci to the lives of Dominican women. I employ Walter Benjamin's theories found in his essays "The Storyteller" (1936) and "On the Concept of History" (1940) to assist my exploration of Alvarez's questions concerning the power and effect of storytelling, and the importance of reconstructing various historical voices and images, specifically, the importance of reconstructing female voices in male dominated cultures. I discuss the …

An Awakened Sense Of Place: Thoreauvian Patterns In Willa Cather's Fiction, Breanne Grover Jul 2006

An Awakened Sense Of Place: Thoreauvian Patterns In Willa Cather's Fiction, Breanne Grover

Theses and Dissertations

The recent "greening" of Willa Cather Scholarship has initiated new conversations about Cather's use of and dependence on landscape in her fiction. Scholars have frequently noted Cather's reliance on landscape imagery, but this thesis suggests parallels between Cather's and Henry David Thoreau's use of awakening imagery and examines how such parallels work in Cather's environmental discussion of wilderness and environmental communities. There is little direct evidence linking the development of Cather to Thoreau, although their similar use of awakening imagery suggests they comment on similar environmental discussions through their writing, indicating that Cather deserves further attention as a nature writer. …

A Solution For Commodity Field Hauling With Self-Unloading Semi-Trailers, Lee Pagens Wilkerson Jul 2006

A Solution For Commodity Field Hauling With Self-Unloading Semi-Trailers, Lee Pagens Wilkerson

Theses and Dissertations

Commodity hauling of bulk goods is a growing enterprise that has expanded from hauling agricultural products to hauling many other bulk products. Commodity trailers are used to haul agricultural products from storage facilities to processing plants. These trailers are designed for highway use but are frequently required to work in field conditions as well. In many cases this environment overstresses these trailers and results in permanent irreparable damage. In addition to the structural problems of these trailers, the current systems for unloading the bulk produce from these trailers have serious inadequacies. While functional, the currently used chain and non-chain driven …

Accuracy Of Automated Developmental Sentence Scoring Software, Carrie Ann Judson Jul 2006

Accuracy Of Automated Developmental Sentence Scoring Software, Carrie Ann Judson

Theses and Dissertations

Developmental Sentence Scoring (DSS; Lee 1974) is a well established, structured method for analyzing a child's expressive syntax within the context of a conversational speech sample. Automated DSS programs may increase efficiency of DSS analysis; however the program must be accurate in order to yield valid and reliable results. A recent study by Sagae, Lavie, and MacWhinney (2005) proposed a new method for analyzing the accuracy of automated language analysis programs. This method was used in addition to previously established methods to analyze the accuracy of a new automated DSS program, entitled DSSA (Channell, 2006). Previously collected language samples from …

The Developmental Timing Of Divorce And Adult Children's Romantic Relationship Quality, Abigail Joy Viveiros Jul 2006

The Developmental Timing Of Divorce And Adult Children's Romantic Relationship Quality, Abigail Joy Viveiros

Theses and Dissertations

Understanding the contingencies that explain whether divorce has positive or negative long-term effects for adult children is at the heart of this study. Although previous studies suggest an association between parental divorce and the divorce of adult offspring, less known is about whether the timing of divorce influences the relationship outcomes of adult children. Using a large nationally representative sample in terms of race (N=6,066), eight groups of individuals (males and females from intact homes, males and females who experienced divorce during adolescence, males and females who experienced divorce during middle childhood, and males and females who experienced divorce during …

Tumor Associated Macrophages In A Mafia Mouse Model, Adrianne Brown Clifford Jul 2006

Tumor Associated Macrophages In A Mafia Mouse Model, Adrianne Brown Clifford

Theses and Dissertations

Recent evidence has shown the important role of macrophages in both tumor development and progression. To investigate the role of macrophages we used a mouse model known as MaFIA (Macrophage Fas Induced Apoptosis) mice that allows for the selective deletion of macrophages. Mice were given melanoma cells at various stages of depletion. Tumor mass was measured and organs were processed for flow cytometry to measure melanoma cell migration. The results show that mice receiving depletion treatment have larger tumor sizes and weights than those mice retaining their macrophage population. We detect metastasis in both the lung and kidney in both …

Design Of A Linear Ultrasonic Piezoelectric Motor, Scott L. Sharp Jul 2006

Design Of A Linear Ultrasonic Piezoelectric Motor, Scott L. Sharp

Theses and Dissertations

A new geometrically unique ultrasonic motor (USM) was designed using finite element modeling (FEM). A USM operates by vibrating a drive tip in an elliptical motion while it is in periodic contact with a driven surface. Piezoelectric elements are used to create the elliptical motions and are driven near a resonant frequency to create the needed displacements for the motor to operate. An idea for a motor frame was conceived that consisted of an arch, a center ground, and two piezoelectric elements connected to the center ground. End caps were added between the frame and the piezoelectric elements to reduce …

Adolescent Leisure Activities As A Moderator Of The Negative Effects Of Family Process On Adolescent Emotional Health, Samuel K. Dahlin Jul 2006

Adolescent Leisure Activities As A Moderator Of The Negative Effects Of Family Process On Adolescent Emotional Health, Samuel K. Dahlin

Theses and Dissertations

The purpose of this study was to investigate whether an adolescent's experience with different types of leisure (achievement, social or time-out) would moderate the negative effects of dysfunctional family process on an adolescent's emotional health. A model was tested that hypothesized that leisure experienced as achievement or social by adolescents would buffer the negative effects of a dysfunctional family. A sample of 243 clinical and non-clinical adolescents completed the Global Severity Index, the Family Assessment Device, and the Leisure Questionnaire. Three regression analyses were run for the whole sample (n=243), the male sample (n=150), and the female sample (n=93). In …

A Microformatted Registry Alternative, Thomas R. Warne Jul 2006

A Microformatted Registry Alternative, Thomas R. Warne

Theses and Dissertations

To effectively use Web services, providers and consumers need to be connected by a registry. Several registry solutions exist today, including UDDI and WSIL. Also, many organizations simply use Web pages to list available Web services and their descriptions. This research describes a microformat for representing Web service description documents. These microformatted documents can be converted back to the original format for use by machines. They can also contain additional information, making them more useful to people. A registry, allowing indexing and searching of microformatted service descriptions, is also described. The benefits of this solution include: using existing standards; allowing …

Local Url Resolution Protocol, Joseph Clark Ekstrom Jul 2006

Local Url Resolution Protocol, Joseph Clark Ekstrom

Theses and Dissertations

DOGMA is a resource management system designed to create a supercomputer like system from unused desktop computers. Scalability is one of the challenges faced by DOGMA because it uses a strict client/server architecture. Distributing large files over a client server architecture is problematic since available network bandwidth is limited. The Local URL Resolution Protocol(LURP) addresses this problem for environments where there are high node densities. LURP implements a locality aware Peer-to-Peer file distribution model to increase the speed of file distribution while reducing the overall network congestion.

Implicit Family Process And Couples Rules: A Comparison Of American And Hungarian Families, Noemi Gergely Jul 2006

Implicit Family Process And Couples Rules: A Comparison Of American And Hungarian Families, Noemi Gergely

Theses and Dissertations

Family life is organized by rules, and most of them are unspokenly agreed-upon by family members and may be even out of awareness. Implicit family process and couple rules may facilitate or constrain family relationship and intimate couple relationship growth. Prevalence of family rules may be different across cultures. Family members may perceive their rules and family functioning differently according to their family position and gender. Married couples may view their relationship rules differently than couples who cohabit. This study utilized the Family Implicit Rules Profile (FIRP) and the Couples Implicit Rules Profile (CIRP) Questionnaires to answer these research questions. …

Crossing Dependencies In Persian, Jonathan M. Dehdari Jul 2006

Crossing Dependencies In Persian, Jonathan M. Dehdari

Theses and Dissertations

Languages occasionally have syntactic constructions that are difficult, if not impossible, to describe using a context-free grammar. One such construction is a crossing dependency. Crossing dependencies have been well studied for Dutch and Swiss German (Huybregts, 1976; Shieber, 1985), and recently for Tagalog (Maclachlan and Rambow, 2003). In this paper I propose that Persian exhibits crossing dependencies. In this SOV language, a light verb construction in the future tense becomes interrupted by a future auxiliary verb, which agrees with its subject in person and number. The future auxiliary also splits passive constructions in a similar manner. These forms present interesting …
