A Provacative Test To Determine Brain Compliance In The Management Of Patients With Hydrocephalus, Preston K. Manwaring Nov 2005

A Provacative Test To Determine Brain Compliance In The Management Of Patients With Hydrocephalus, Preston K. Manwaring

Theses and Dissertations

Non-invasive techniques to explore intracranial compliance and pressure have been extensively explored in recent years. Previous techniques have used expensive technologies to make these measurements, often with difficulty. We present a novel, inexpensive provocative test to observe trends in intracranial compliance measurement targeted towards the treatment and management of hydrocephalus. Two techniques are proposed which derive data from the digital and supraorbital arteries as well as tympanic membrane displacement. This requires the use of two photo-plethysmographic sensors and a TMD sensor. A common tilt table apparatus is used to methodically and artificially increase intracranial pressure to stress the cranial system …

Highly Efficient Fluorescence Detection In Picoliter Volume Liquid-Core Waveguides, Aaron R. Hawkins, John P. Barber, Dongliang Yin Nov 2005

Highly Efficient Fluorescence Detection In Picoliter Volume Liquid-Core Waveguides, Aaron R. Hawkins, John P. Barber, Dongliang Yin

Faculty Publications

We report loss improvement and fluorescence detection in integrated antiresonant reflecting optical waveguides with liquid cores. The minimum waveguide loss is reduced to 0.33/cm by compensating for thickness variations in the fabrication process. We demonstrate fluorescence detection from as few as 490 molecules in a 57 pl core using these optimized waveguides. We measure angular fluorescence collection factors as high as 15% per facet in good agreement with theory. This demonstrates the potential of integrated hollow-core waveguides as optical sensors for single-molecule spectroscopy.

Generating Medical Logic Modules For Clinical Trial Eligibility, Craig G. Parker Nov 2005

Generating Medical Logic Modules For Clinical Trial Eligibility, Craig G. Parker

Theses and Dissertations

Clinical trials are important to the advancement of medical science. They provide the experimental and statistical basis needed to determine the benefit of diagnostic and therapeutic agents and procedures. The more patients enrolled in a clinical trial, the more confidence we can have in the trial's results. However, current practices for identifying eligible patients can be expensive and time-consuming. To assist in making identification of eligible patients more cost effective, we have developed a system for translating the eligibility criteria for clinical trials to an executable form. This system takes as input the eligibility criteria for a trial formatted as …

Development And Validation Of The Theistic Spiritual Outcome Survey, P. Scott Richards, Timothy B. Smith, Marion Schowalter, Michael E. Berrett, Randy K. Hardman

Faculty Publications

We developed the Spiritual Outcome Scale (SOS) to measure the spiritual outcomes of psychotherapy from a theistic spiritual perspective. A 17-item version of the SOS was found to have adequate reliability and validity in a sample of college students. Three factors emerged from the analyses that corresponded to subscales labeled Love of God, Love of Others, and Love of Self. Correlations with measures of psychological outcomes were statistically significant. In subsequent analyses, the SOS was administered over an 8-week period to a sample of inpatient women with eating disorders and to two samples from inpatient psychological clinics in Germany. The …

Natural History Of A Retreat-Building Midge, Pagastia Partica, In A Regulated Reach Of The Upper Colorado River, Jeremy B. Monroe, N. Leroy Poff, Richard A. Thorp

Western North American Naturalist

The retreat-building midge Pagastia prob. partica (Roback) is an abundant and conspicuous member of the benthic community of the upper Colorado River. We investigated the ecology and behavior of P. partica in this regulated stream using both qualitative observations and quantitative surveys. Our studies revealed that P. partica foraged primarily by grazing algae from their retreats and adjacent surfaces and exhibited territorial behavior toward other P. partica larvae. Pagastia partica were widely distributed among streambed surfaces but preferred those with higher biomasses of periphyton and swifter currents. The retreats of P. partica were composed largely of silk and colonized algae …

Event Related Potentials: A Study Of The Processing Of Gapping Structures In Adolescents, Michelle Miller Nishida Nov 2005

Event Related Potentials: A Study Of The Processing Of Gapping Structures In Adolescents, Michelle Miller Nishida

Theses and Dissertations

Many questions remain unanswered regarding the intricacies of the human brain, especially with regard to the complexities of language processing. One essential component of human sentence processing is the ability to detect, decipher, and recover from errors in the interpretation of both verbal and written language. This process of repair of ungrammatical sentences and revision or reinterpretation of ambiguous sentences has been studied extensively in recent years. A variety of tools have been developed, including the use of event-related potentials (ERPs) in order to assess how language is processed and developed, and to help better identify the nature of these …

Facilitating Communication About Death Between Mothers And Adolescent Sons Using Fictional Children's Literature, Deon G. Leavy Nov 2005

Facilitating Communication About Death Between Mothers And Adolescent Sons Using Fictional Children's Literature, Deon G. Leavy

Theses and Dissertations

Most children will experience the death of a loved one in their lifetime and will need to develop healthy grieving patterns. Communication between parents and children is a key ingredient in facilitating this development. Current opinions about bibliotherapy, using a book to assist in healing, suggest that books provide understanding about grief and death and open channels of communication. Although the use of bibliotherapy is gaining popularity, little research exists about its efficacy. Utilizing the book The Bridge to Terabithia, this study evaluated the facilitation of communication about death between 19 dyads of mother and adolescent sons. Their answers and …

From Here To There: Memoirs Of A Swiss Childhood, Ellen Carney Nov 2005

From Here To There: Memoirs Of A Swiss Childhood, Ellen Carney

Swiss American Historical Society Review

Flags are the hallmark of August ist, a day steeped in tradition and legend. Flags are flown all year round, but they serve mainly decorative purposes on mountain tops, steam boats and on occasion, a church tower. The bright red square with the white cross livens up the green (or white) countryside, gray city streets and certainly looks photogenic against the blue sky of calendar pages. Swiss love their flag but don't pledge allegiance to it, not even on this day when it assumes a patriotic dimension and is flown everywhere, from ordinary buildings, across narrow streets in the old …

Influences Of Dietary Soy Isoflavones On Metabolism But Not Nociception And Stress Hormone Responses In Ovariectomized Female Rats, Edwin D. Lephart, Lihong H. Bu, Kenneth Setchell

Faculty Publications

Isoflavones, the most abundant phytoestrogens in soy foods, are structurally similar to 17beta-estradiol. Few studies have examined the nociception and stress hormone responses after consumption of soy isoflavones. Methods: In this study, ovariectomized (OVX) female Long-Evans rats were fed either an isoflavone-rich diet (Phyto-600) or an isoflavone-free diet (Phyto-free). We examined the effects of soy isoflavones on metabolism by measuring body weights, food/water intake, adipose tissue weights as well as serum leptin levels. Also, circulating isoflavone levels were quantified. During chemically induced estrous, nociceptive thresholds were recorded. Then, the animals were subjected to a stressor and stress hormone levels were …

Murals And The Development Of Merchant Activity At Chichen Itza, De Luna Lucha Aztzin Martinez Oct 2005

Murals And The Development Of Merchant Activity At Chichen Itza, De Luna Lucha Aztzin Martinez

Theses and Dissertations

The militaristic interpretations of the art of Chichen Itza, Yucatán, Mexico, fails to sufficiently describe its entire decorative program. Absent from discussions of the art tradition is the apparent focus on merchant activity in the city. The influence and power of merchants strengthened during the transition from the Classic to Postclassic in Mesoamerica. With an increase in demand of foreign goods, new exchange relationships developed between centers in Central Mexico, the Gulf, and Maya region. As a result, several cultural regions participated in a vast economic network that created political alliances and syncretic art styles. Focusing on the mural tradition …

Moral Responsiveness And Discontinuity In Therapy: A Qualitative Study, Jason B. Whiting Phd, R. Scott Nebeker, Stephen T. Fife Oct 2005

Moral Responsiveness And Discontinuity In Therapy: A Qualitative Study, Jason B. Whiting Phd, R. Scott Nebeker, Stephen T. Fife

Faculty Publications

Phenomenological qualitative methods were used to identify and describe moral elements in therapeutic relationships. Using the relational philosophy of E. Levinas (1961/1969, 1979/1987) as a base, data in which therapists and clients identified and described morally responsive experiences in therapy sessions were analyzed. These moments were often unexpected and included categories of surprise, interruption, willingness to change, and clarifications/repairs. Additional moral phenomena related to therapists' attitudes included asymmetrical indebtedness, attitude of serving, and tentativeness of diagnosis. Identified moments of moral responsiveness were frequently associated with clients' progress in therapy. This suggests that conceptually smooth and uninterrupted therapy may be less …

Acoustic And Spectral Characteristics Of Young Children's Fricative Productions: A Developmental Perspective, Shawn L. Nissen, Robert Allen Fox

Faculty Publications

Scientists have made great strides toward understanding the mechanisms of speech production and perception. However, the complex relationships between the acoustic structures of speech and the resulting psychological percepts have yet to be fully and adequately explained, especially in speech produced by younger children. Thus, this study examined the acoustic structure of voiceless fricatives (/f, θ, s, ʃ/) produced by adults and typically developing children from 3 to 6 years of age in terms of multiple acoustic parameters (durations, normalized amplitude, spectral slope, and spectral moments). It was found the acoustic parameters of spectral slope and variance (commonly excluded from …

Rate-Adaptive Runlength Limited Encoding For High-Speed Infrared Communication, James Cyril Funk Sep 2005

Rate-Adaptive Runlength Limited Encoding For High-Speed Infrared Communication, James Cyril Funk

Theses and Dissertations

My thesis will demonstrate that Rate Adaptive Runlength Limited encoding (RA-RLL) achieves high data rates with acceptable error rate over a wide range of signal distortion/attenuation, and background noise. RA-RLL has performance superior to other infrared modulation schemes in terms of bandwidth efficiency, duty cycle control, and synchronization frequency. Rate adaptive techniques allow for quick convergence of RA-RLL parameters to acceptable values. RA-RLL may be feasibly implemented on systems with non-ideal timing and digital synchronization.

How Family Religious Involvement Benefits Adults, Youth, And Children And Strengthens Families, David C. Dollahite, Jennifer Y. Thatcher Sep 2005

How Family Religious Involvement Benefits Adults, Youth, And Children And Strengthens Families, David C. Dollahite, Jennifer Y. Thatcher

Faculty Publications

A growing body of empirical research demonstrates that a family’s religious involvement directly benefits adults, children and youth in many ways. Divorce rates are lower and marital satisfaction and quality scores highest among religiously involved couples. Religious practices are linked with family satisfaction, closer father-child relationships, and closer parent-child relationships. There is less domestic violence among more religious couples and religious parents are less likely to abuse or yell at their children. Religious involvement promotes involved and responsible fathering and is associated with more involved mothering. Greater religiosity in parents and youth is associated with a variety of protective factors …

A Witness In England: Martin Harris And The Strangite Mission, Robin Scott Jensen Sep 2005

A Witness In England: Martin Harris And The Strangite Mission, Robin Scott Jensen

BYU Studies

Throughout his long life, Martin Harris (fig. 1) consistently testified that he knew Joseph Smith translated the Book of Mormon from golden plates. At first affiliated with Joseph Smith and the main body of The Church of Jesus Christ of Latter-day Saints, for a time Harris associated with a schism led by James J. Strang. He served a mission in England in 1846 for the Strangites, but he claimed to the end of his life that he had never preached against Mormonism or against the Book of Mormon. Indeed, he was a powerful witness of the Book of Mormon during …
