An Analysis Of The Newspaper Coverage Of Latter-Day Saint Temples Announced Or Built Within The United States From October 1997 Through December 2004, Kevan L. Gurr

Theses and Dissertations

President Gordon B. Hinckley, the fifteenth president of The Church of Jesus Christ of Latter-day Saints, excited the membership of the Church by increasing the number of temples available to members. He announced that the Church would construct smaller buildings – as compared with existing temples at the time – thereby allowing for greater numbers of temples to be built. He set a goal to build 50 temples in a two and half-year period: double the number the Church had ever attempted to build in any decade. Thirty-four of these temples were built in the United States, and newspapers – …

The Etoile Du Deseret: Portrait Of The French Mission, 1851-1852, Douglas James Geilman

Theses and Dissertations

One of John Taylor's most significant achievements during his mission to France, 1849-1851, was the publication of a French-language Latter-day Saint periodical, the Etoile du Déséret. Appearing in twelve issues from May 1851 to December 1852, the Etoile served a variety of functions for the earliest missionaries and members of The Church of Jesus Christ of Latter-day Saints in France. A study of its historical context and of its contents allows readers a glimpse into the circumstances under which the missionaries labored and into the needs of the growing Church. Furthermore, the Etoile provides a vivid example of John …

Danish Anti-Americanism: A Socio-Cultural Perspective, Poul Houe

The Bridge

In the spring of 2002, Granta, the distinguished "Magazine of New Writing," put out a special issue in which "twenty-four writers drawn from many countries" reflect on "What We Think of America." On the magazine's back cover, the occasion for their musings is presented as follows:

The September 11 attacks on the US provoked shock and pity in the rest of the world, but mingled with the sympathy was something harsher: anti-Americanism. It wasn't confined to the West Bank or Kabul. It could be heard in English country pubs, in the bars of Paris and Rome, the tea stalls of …

Development Of A Process Of Addition Of Tricalcium Phosphate From Burnt Phosphate Rock In Feed For Animal Nutrition, Luis Fernando Nogales Grágeda

Theses and Dissertations

This study took place in Bolivia with the purpose of using thermally treated Capinota phosphate rock as a phosphorous supplement in balanced feed diets. The objective was to produce a natural phosphate substance that would be more easily accessible to the local population than commercial feed supplements. An additional objective of this study was to increase the availability of the low-fluoride phosphorous. The biological assays indicated that the diet with the added burned phosphoric rock produced similar yields to those using a commercial feed supplement (dicalcium phosphate). This indicates that the locally manufactured product, by partial acidification, can compete with …

A Diabolical Disneyland In Zion: The Mormons And The Mx, Jacob W. Olmstead

Theses and Dissertations

In September 1979 President Jimmy Carter publicly announced his decision to support the deployment of the MX missile and mobile basing scheme in Utah and Nevada. Despite local opposition and the close proximity of the proposed base to its headquarters, The Church of Jesus Christ of Latter-day Saints (Mormons) remained silent until 5 May 1981, when the First Presidency issued a statement opposing the MX plans. The purpose of this work is to narrate the history of the development of the Mormon position regarding the deployment of MX missile in the Great Basin and evaluate the response to the statement …

Polymerization Kinetics Of Peo-B-Pnipaam Block Copolymers, William G. Pitt, Yi Zeng

Faculty Publications

Our research in ultrasonic activated drug delivery motivated us to develop polymeric micelles that sequester hydrophobic drugs (Fig. 1) until they are sheared open by cavitation events produced by low frequency ultrasound (Fig. 2). [1] Using this type of drug delivery system, micelles sequestering drug can circulate freely without releasing their drug until they flow through a tumor or other tissue insonated by low frequency ultrasound. There they release part of their drug (Fig. 3). [2,3] This drug delivery technology was used to reduce tumors in a rat model [4] using block copolymers of PEO and PPO. However, we are …

Attitudes Toward Abortion Among Religious Traditions In The United States: Change Or Continuity?, John P. Hoffmann, Sherrie Mills Johnson

Faculty Publications

Abortion continues to be a highly contentious issue in the United States, with few signs of abatement. The goal of this paper is to specify how variable positions about abortion across religious traditions have led to differential shifts in attitudes among their members. Based on culturally relevant events, position papers, and other religious media, the guiding hypotheses propose that Evangelicals have become increasingly opposed to abortion for elective reasons; yet changes in attitudes regarding abortion for traumatic reasons are due primarily to cohort shifts. Data from the cumulative General Social Surveys (1972–2002) are used to test the hypotheses. The first …

Mechanism Of Targeted Chemotherapeutic Delivery Using Ultrasound, Thaidra A. Gaufin, Byron K. Murray, Seiga Ohmine, Kim L. O'Neill, William G. Pitt, Briant S. Stringham

Faculty Publications

Ultrasound (US) is used to enhance and target delivery of drugs and genes to cancer tissues. The advantages of focused delivery to select tissues are manifold, but the exact mechanisms are largely unknown and need clarification to optimize delivery. The present study further defined the role of collapse cavitation in US-induced permeabilization of cell membranes and subsequent drug or gene uptake by the cell. Cavitation, defined as the collapse of micro-bubbles, produces high shear stresses and shock waves that may transiently puncture cell membranes and has been suggested as the cause of increased permeability. The hypothesis that collapsing bubbles permeabilize …

The purpose of this study was to develop, digitally record, evaluate, and psychometrically equate a set of Mandarin bisyllabic word lists for use in measurement of speech discrimination. Familiar bisyllabic words were digitally recorded by male and female talkers of Standard Mandarin. Percentage of correct word recognition was measured for each word at ten intensity levels ( /5 to 40dB HL) in 5 dB increments using 20 normally hearing subjects. Using logistic regression, 200 words with the steepest logistic regression slopes were included in four psychometrically equivalent word lists of 50 words each, and eight half-lists of 25 words each. …

The Effect Of Prostaglandin Inhibitor On Pregnancy Rates Of Heifer Embryo Transfer Recipients, Jared William Mcnaughtan

Theses and Dissertations

Manipulation of the reproductive tract results in increased levels of prostaglandin, which may, in turn, reduce pregnancy rates in embryo recipients. Administration of a prostaglandin inhibitor prior to embryo transfer improves pregnancy rates in cows. Embryo transfer into heifers is more difficult and often requires additional manipulation of the uterus. This study was designed to determine whether administration of the prostaglandin inhibitor, flunixin meglumine, immediately prior to embryo transfer increases pregnancy rates in heifers. Heifers (n=466) were divided into two equal groups based on BCS (range=6-7) and weight (range=256-455). Estrus was synchronized in heifers by giving two injections of prostaglandin …

Representations Of Anglo-Saxon England In Children's Literature, Kirsti A. Bobo

Theses and Dissertations

This thesis surveys the children's literary accounts of Anglo-Saxon history and literature that have been written since the mid-nineteenth century. Authors of different ages emphasize different aspects of Anglo-Saxon culture as societal need for and interpretation of the past change. In studying these changes, I show not only why children's authors would choose to depict the Saxons in their writing, but why medievalists would want to study the resulting literature.

My second chapter looks at children's historical fiction and nonfiction, charting the trends which appear in the literature written between 1850 and the present day. I survey the changes made …

New Product Launch Decisions Under Competition And Uncertainty: A Real Options And Game-Theoretic Approach To New Product Development, James O. Ostler

Theses and Dissertations

New product development is central to many firms' future success. Not only as a means to continue to maintain their piece of the market, but product development can also be a strategic means for a company to diversify, and/or alter focus to adapt to changing market conditions.

Most of the research in new product development has been on how to do it cheaper and faster than the next guy. However, early commercialization does not guarantee a position of strength in the market. Failures of EMI in CT scanners and Xerox in personal computers illustrate that being first to market does …

Atomic Force Microscope Conductivity Measurements Of Single Ferritin Molecules, Degao Xu

Theses and Dissertations

Conductive Atomic Force Microscope (c-AFM) was used to measure the conductivity of single horse spleen ferritin (HoSF) and azotobacter vinelandii bacterial ferritin (AvBF) molecules deposited on flat gold surfaces. A 500 micron diameter gold ball was also used as a contact probe to measure the conductivity of a thin film of ferritin molecules. The average current measured for holo HoSF was 13 and 5 times larger than that measured for apo HoSF as measured by c-AFM at 1V and gold ball at 2V and respectively, which indicates that the core of ferritin is more conductive than the protein shell and …

The Strength Of Multidimensional Item Response Theory In Exploring Construct Space That Is Multidimensional And Correlated, Steven Gerry Spencer

Theses and Dissertations

This dissertation compares the parameter estimates obtained from two item response theory (IRT) models: the 1-PL IRT model and the MC1-PL IRT model. Several scenarios were explored in which both unidimensional and multidimensional item-level and personal-level data were used to generate the item responses. The Monte Carlo simulations mirrored the real-life application of the two correlated dimensions of Necessary Operations and Calculations in the basic mathematics domain. In all scenarios, the MC1-PL IRT model showed greater precision in the recovery of the true underlying item difficulty values and person theta values along each primary dimension as well as along a …

Dynamic Stability And Handling Qualities Of Small Unmanned-Aerial-Vehicles Unmanned-Aerial-Vehicles, Tyler Michael Foster

Theses and Dissertations

General aircraft dynamic stability theory was used to predict the natural frequencies, damping ratios and time constants of the dynamic modes for three specific small UAVs with wingspans on the scale from 0.6 meters to 1.2 meters. Using USAF DatCom methods, a spreadsheet program for predicting the dynamic stability and handling qualities of small UAVs was created for use in the design stage of new small UAV concept development. This program was verified by inputting data for a Cessna-182, and by then comparing the program output with that of a similar program developed by DAR Corporation. Predictions with acceptable errors …

A Finite Element Simulation Of Temperature And Material Flow In Fricton Stir Welding, Mark J. Lasley

Theses and Dissertations

The purpose of this research was to use the Transvalor S.A. product, Forge3, to develop a finite element simulation of the friction stir welding process that improves the predictability of temperature evolution and material flow within the plunge portion of the process. Previous modeling created more heating within the billet than experimental results, probably due to the simplification of the simulation with adiabatic boundary conditions. More realistic tooling temperatures were included in this model as these affect heat evolution which is a determining factor in microcrystalline growth. These results were validated by experimental efforts using a billet and tooling instrumented …

Wave Scattering From Infinite Cylindrical Obstacles Of Arbitrary Cross-Section, Matthew B. Weber

Theses and Dissertations

In this work the scattering of an incident plane wave propagating along a plane perpendicular to the xy-plane is studied. The wave is scattered from an infinitely long cylindrical object of arbitrary cross-section. Due to the arbitrary geometry of the obstacle, a finite differences numerical method is employed to approximate the solution of the scattering problems. The wave equation is expressed in terms of generalized curvilinear coordinates. Boundary conforming grids are generated using elliptic grid generators. Then, a explicit marching in time scheme is implemented over these grids. It is found that as time grows the numerical solution converges to …
