Influence Of Adapted Sport On Quality Of Life: Perceptions Of Athletes With Cerebral Palsy, Diane G. Groff, Neil R. Lundberg, Ramon Zabriskie

Faculty Publications

Purpose: This study sought to examine the effect of adaptive sports participation on athletic identity and influence on quality of life (QOL) for individuals with cerebral palsy (CP) participating in the CP World Games.

Method: Surveys were conducted with 73 international athletes competing in the 2005 CP World Championships. The survey included descriptive questions about sport involvement and socio-demographics, the Athletic Identity Measurement Scale, and the Influence on Quality of Life Scale.

Results: A significant relationship was found between influence on QOL and athletic identity (r¼0.505; p50.001). There was a moderate negative correlation between influence of adaptive sport …

Automatic, Multimodal Evaluation Of Human Interaction, Matthew L. Jensen, Thomas O. Meservy, Judee K. Burgoon, Jay F. Nunamaker Jr.

Faculty Publications

This article outlines an approach for automatically extracting behavioral indicators from video, audio, and text and explores the possibility of using those indicators to predict human-interpretable judgments of involvement, dominance, tension, and arousal. We utilized two-dimensional spatial inputs extracted from video, acoustic properties extracted from audio and verbal content transcribed from face-toface interactions to construct a set of multimodal features.Multiple predictive models were created using the extracted features as predictors and human-coded perceptions of involvement, tenseness, and arousal as the criterion. These predicted perceptions were then used as independent variables in classifying truth and deception. Though the predicted values for …

Latter-Day Saint Children And Youth In America, David C. Dollahite

Faculty Publications

Some of the concepts of the view of the childhood held by the Latter-day Saints can be found in stories told about the early life of their founder and first prophet, Joseph Smith. Brother Joseph, as he was known to the Saints, often took time to play games with children and youth. Some Mormons, with their early American sense of propriety about religious leaders, were troubled by Joseph's playful nature. One day a Brother Wakefield came to the Prophet's home to discuss church business. He was told that Brother Joseph was translating the word of God. Brother Wakefield waited some …

Ten Scalability Factors In Distance Education, R. Dwight Laws, Scott L. Howell, Nathan K. Lindsay

Faculty Publications

The institutional decision about how much technology should be used to scale distance education enrollments, reduce costs, maximize profits, and protect course and program quality is both institutional specific and complex. Guri-Rosenblit (1999) noted that “many conventional universities worldwide operate as large-scale universities and are in a continuous search to find the right balance between massification trends, quality education, and the catering to the individual needs of students” (p. 289). This research is an outgrowth of the authors’ own efforts to identify relevant scalability factors and their interrelationship one to another in a traditional university’s distance education program.

Dialect Identification: The Effects Of Religion Of Origin And Amount Of Experience, Wendy Baker-Smemoe, David Eddington, Lyndsey Nay

Faculty Publications

This study examines whether two factors, region of origin (i.e., being from either Utah, Western states, or non-Western states) and amount of experience for those not native to Utah (having less than one, more than one but less than five, or over five years living in Utah), influence how well listeners are able to distinguish between Utah and non-Utah speakers and what phonetic characteristics they use to do so. The results suggest that the more similar the listener’s dialect is to Utah English, the better his or her ability to identify Utah speakers. Moreover, it was found that listeners from …

Imaginative Instruction: What Master Storytellers Can Teach Instructional Designers, Jason K. Mcdonald

Faculty Publications

Good instructional storytelling engages students’ attention and cognitive abilities to the end of more effective learning, and instructional researchers have discussed whether the principles of storytelling could lead to the same or similar results if applied to educational situations beyond only telling traditional stories. But despite this potential, the principles of storytelling are seemingly underutilized by today’s instructional designers. This study investigates what instructional designers might learn from another design field that is more experienced in the art of storytelling, specifically that of film production. Eight filmmakers who have successfully produced films that motivate, inspire, and educate were interviewed to …

The Cmc Interactivity Model: How Interactivity Enhances Communication Quality And Process Satisfaction In Lean-Media Groups, Paul Benjamin Lowry, Nicholas C. Romano Jr., Jeffrey L. Jenkins, Randy W. Guthrie

Faculty Publications

Process satisfaction is one important determinant of work group collaborative system adoption, continuance, and performance. We explicate the computermediated communication (CMC) interactivity model (CMCIM) to explain and predict how interactivity enhances communication quality that results in increased process satisfaction in CMC-supported work groups. We operationalize this model in the challenging context of very large groups using extremely lean CMC. We tested it with a rigorous field experiment and analyzed the results with the latest structural equation modeling techniques. Interactivity and communication quality dramatically improved for very large groups using highly lean CMC (audience response systems) over faceto- face groups. Moreover, …

Lost Generations? Indigenous Population Of The Russian North In The Post-Soviet Era, Andrey N. Petrov

Faculty Publications

This paper discusses key findings concerning population dynamic of the Indigenous minorities living in the Russian North during the post-Soviet period, highlighted by the 2002 Census. The paper places recent demographic trends into the context of past and current economic, social and institutional changes. It also provides comparisons with Indigenous population dynamics in other parts of the Arctic. Although most Indigenous peoples of the Russian North were growing numerically, they still experienced effects of Russia’s economic crisis, primarily reflected in rapidly falling fertility and rising mortality in the middle-age cohorts. In addition, both the ethnic drift and legal changes seriously …

The Role Of Msa In Staphylococcus Aureus Biofilm Formation, Karthik Sambanthamoorthy, Antony Schwartz, Vijayaraj Nagarajan, Mohamed O. Elasri

Faculty Publications

Background

Staphylococcus aureus is an important pathogen that forms biofilms. The global regulator sarA is essential for biofilm formation. Since the modulator of sarA (msa) is required for full expression of sarA and regulates several virulence factors, we examined the capacity of the msa mutant to form biofilm.

Results

We found that mutation of msa results in reduced expression of sarA in biofilm and that the msa mutant formed a weak and unstable biofilm. The msa mutant is able to adhere to surfaces and begins to form biofilm but fails to mature indicating that the defect of the …

Uva-Induced Photo Recovery During Early Zebrafish Embryogenesis, Qiaoxiang Dong, W. Todd Monroe, Terrence R. Tiersch, Kurt R. Svoboda

Faculty Publications

DNA photorepair has been widely studied in simple aquatic organisms that live in the marine environment, but is less understood in more complex species that live in freshwater. In the present study, we evaluated UVA-induced DNA photo recovery in embryonic stages of zebrafish, Danio rerio, a freshwater model species. Evaluation of UVB exposure and UVA photo recovery of zebrafish embryos revealed different UVB tolerances and capacities for UVA photo recovery at different stages of development. Effective UVA photo recovery was observed at 3 h post-fertilization (hpf), 6-7 hpf, and 12 hpf, but not in the early cleavage stage (2-32 cells). …

Two Evolutionarily Conserved Sequence Elements For Peg3/Usp29 Transcription, Jeong Do Kim, Sungryul Yu, Jung Ha Choo, Joomyeong Kim

Faculty Publications

Background: Two evolutionarily Conserved Sequence Elements, CSE1 and CSE2 (YY1 binding sites), are found within the 3.8-kb CpG island surrounding the bidirectional promoter of two imprinted genes, Peg3 (Paternally expressed gene 3) and Usp29 (Ubiquitin-specific protease 29). This CpG island is a likely ICR (Imprinting Control Region) that controls transcription of the 500-kb genomic region of the Peg3 imprinted domain. Results: The current study investigated the functional roles of CSE1 and CSE2 in the transcriptional control of the two genes, Peg3 and Usp29, using cell line-based promoter assays. The mutation of 6 YY1 binding sites (CSE2) reduced the transcriptional activity …

The Gendered Meanings Of Assets For Divorce, Jeffrey P. Dew

Faculty Publications

Scholars identified a negative relationship between assets and divorce decades ago, but the mechanisms behind this relationship remain unknown. Using data from the National Survey of Families and Households (N = 4,721 couples), this study compared three mechanisms that might link assets and divorce. Non-proportional Cox hazard models indicated that two of the three mechanisms explained the relationship between assets and divorce. Wives’ marital satisfaction and their perceptions of their hypothetical post-divorce standard of living completely mediated the relationship between assets and divorce. The relationship between assets and divorce was not related to husbands’ characteristics.

Identification Of Adropin As A Secreted Factor Linking Dietary Macronutrient Intake With Energy Homeostasis And Lipid Metabolism, K. Ganesh Kumar, James L. Trevaskis, Daniel D. Lam, Gregory M.

Dong, Heather A. Halem, Michael D. Culler, Lora K. Heisler, Jacqueline M. Stephens, Andrew A. Butler

Faculty Publications

Obesity and nutrient homeostasis are linked by mechanisms that are not fully elucidated. Here we describe a secreted protein, adropin, encoded by a gene, Energy Homeostasis Associated (Enho), expressed in liver and brain. Liver Enho expression is regulated by nutrition: lean C57BL/6J mice fed high-fat diet (HFD) exhibited a rapid increase, while fasting reduced expression compared to controls. However, liver Enho expression declines with diet-induced obesity (DIO) associated with 3 months of HFD or with genetically induced obesity, suggesting an association with metabolic disorders in the obese state. In DIO mice, transgenic overexpression or systemic adropin treatment attenuated hepatosteatosis and …

Escherichia Coli Ftna Acts As An Iron Buffer For Re-Assembly Of Iron-Sulfur Clusters In Response To Hydrogen Peroxide Stress, Jacob P. Bitoun, Genfu Wu, Huangen Ding

Faculty Publications

Iron-sulfur clusters are one of the most ubiquitous redox centers in biology. Ironically, iron-sulfur clusters are highly sensitive to reactive oxygen species. Disruption of iron-sulfur clusters will not only change the activity of proteins that host iron-sulfur clusters, the iron released from the disrupted iron-sulfur clusters will further promote the production of deleterious hydroxyl free radicals via the Fenton reaction. Here, we report that ferritin A (FtnA), a major iron-storage protein in Escherichia coli, is able to scavenge the iron released from the disrupted iron-sulfur clusters and alleviates the production of hydroxyl free radicals. Furthermore, we find that the iron …

Tfiiic Binding Sites Function As Both Heterochromatin Barriers And Chromatin Insulators In Saccharomyces Cerevisiae, Tiffany A. Simms, Sandra L. Dugas, Jason C. Gremillion, Megan E. Ibos, M. Nicole Dandurand, Tasha T. Toliver, Daniel J. Edwards, David Donze

Faculty Publications

Chromosomal sites of RNA polymerase III (Pol III) transcription have been demonstrated to have "extratranscriptional" functions, as the assembled Pol III complex can act as chromatin boundaries or pause sites for replication forks, can alter nucleosome positioning or affect transcription of neighboring genes, and can play a role in sister chromatid cohesion. Several studies have demonstrated that assembled Pol III complexes block the propagation of heterochromatin-mediated gene repression. Here we show that in Saccharomyces cerevisiae tRNA genes (tDNAs) and even partially assembled Pol III complexes containing only the transcription factor TFIIIC can exhibit chromatin boundary functions both as heterochromatin barriers …

Micro Radio And The Internet: Dissent Network Formation In Media Based Collective Action, Ted Coopman

Faculty Publications

The movement to establish a grassroots community radio system in the U.S. in the 1990s coincided with the rise of the internet. The impact of internet on media based collective action highlighted shortcomings in existing theory. To address this, I develop a dissent network approach. Utilizing participant observation I apply my measures of consensus on system failure, relational density, process and resource sharing, and the centrality of digital networks to the case of micro radio.

Magnetism And Homogenization Of Microresonators, Robert V. Kohn, Stephen P. Shipman

Faculty Publications

Arrays of cylindrical metal microresonators embedded in a dielectric matrix were proposed by Pendry et al. [IEEE Trans. Microw. Theory Tech., 47 (1999), pp. 2075.2084] as a means of creating a microscopic structure that exhibits strong bulk magnetic behavior at frequencies not realized in nature. This behavior arises for H-polarized fields in the quasi-static regime, in which the scale of the microstructure is much smaller than the free-space wavelength of the fields. We carry out both formal and rigorous two-scale homogenization analyses, paying special attention to the appropriate method of averaging, which does not involve the usual cell averages. We …

Three-Dimensional Seismic Analysis Of High-Amplitude Anomalies In The Shallow Subsurface Of The Northern Indus Fan: Sedimentary And/Or Fluid Origin, Géròme Calvès, Mads Huuse, Anne Schwab, Peter Clift

Faculty Publications

We report on a detailed analysis of amplitude anomalies in three-dimensional (3D) seismic reflection data and their surrounding strata in the shallow subsurface of the northern part of the Indus Submarine Fan, Arabian Sea. Our analysis reveals the presence of distributary lobe complexes and a relict fluid migration system, including a buried mud volcano, linked to contractional anticlines overlying deep-seated strike-slip faults buried below the Indus slope. Building on a regional tectonic and stratigraphic framework, we have used a 3D seismic survey to map in detail the occurrence of high-amplitude anomalies in the shallow subsurface. We link these to gas …

The Use Of A Summary Journal Assignment To Promote Theory And Practice Integration In Experientially Based Courses, Adele Baruch Phd, Ju Hong-Chittaphong, Christine Potaczala

Faculty Publications

The authors discuss the use of a summary journal, an assignment designed to facilitate the integration of theory and course experience in practice-based Counsellor Education courses. The reflections on the assignment are provided by the instructor and two students, from two different practice-based courses. The summary journal does appear to provide an opportunity for students to compare their own experiences with formal theory presented in class and in texts, although the quality of this integration varies. The provision of prior student summaries appears to be helpful to those students who are inexperienced in constructing theoretical meaning out of their own …

Civility In Schools: An Emerging Paradigm For Behavioral Problems And School Violence, Keely Wilkins, Paul Caldarella, K. Richard Young

Faculty Publications

What is Civility? Modern: courtesy, politeness, consideration, decorum (Hinckley, 2000; Peck, 2002, Ferriss, 2002). Historical: ability to work as a citizen, a sense of membership in a community with its attendant rights and responsibilities (Shulman & Carey, 1984; Boyd, 2006).

Synthesis And Spectroelectrochemistry Of N-Cobaltacarborane Porphyrin Conjugates, Erhong Hao, Min Zhang, E. Wenbo, Karl M. Kadish, Frank R. Fronczek, Brandy H. Courtney, M. Graça H. Vicente

Faculty Publications

N-Substituted porphyrins are well-known for the distortion they exhibit of the porphyrin plane through the sp3 hybridization of one of the pyrrolenic units. They have served as model compounds in investigations of many biochemical processes. In this paper, we developed an efficient route to N-substituted porphyrins, and report the synthesis of a series of new N-substituted cobaltacarborane - porphyrins containing one or two cobaltabisdicarbollide anions linked by (CH2CH2O) 2 chains to either the core porphyrin nitrogens or to a meso-aminophenyl group. These conjugates show different degrees of distortion of the porphyrin macrocycle, which affect their spectroscopic and electrochemical properties. In …

Breast Cancer Fatalism: The Role Of Women's Perceptions Of The Health Care System, Allyson G. Hall, Amal J. Khoury, Ellen D.S. Lopez, Nedra Lisovicz, Amanda Avis-Williams, Amal K. Mitra

Faculty Publications

Cancer fatalism, which can be understood as the belief that cancer is a death sentence, has been found to be a deterrent to preventive cancer screening participation. This study examines factors associated with breast cancer fatalism among women. We analyzed data from a 2003 survey of women 40 years of age. The survey collected information about respondents' knowledge and attitudes regarding breast health. Analyses compared the characteristics of women who reported and those who did not report a fatalistic attitude. Women with a fatalistic attitude were more likely to be African American, to have a family history of breast cancer, …

Restoration Of Dredged Canals In Wetlands: A Comparison Of Methods, Joseph Baustian, R. Eugene Turner, Nancy F. Walters, David P. Muth

Faculty Publications

A comparison of two methods for restoring dredged canals to wetlands was examined at the Jean Lafitte National Historical Park and Preserve’s Barataria Preserve Unit near New Orleans, LA. Both northern and southern canals had the remnant dredged spoil material returned to the canal, but the southern canal had additional sediment pumped in from a nearby lake. The water depth in the southern canal shallowed significantly from 1.2 to 0.4 m following backfilling and sediment addition, while the depth of the northern canal (which received no additional sediment) remained unchanged following backfilling. Neither site had complete soil restoration, but the …

Drought Stress And Preharvest Aflatoxin Contamination In Agricultural Commodity: Genetics, Genomics And Proteomics, Baozhu Guo, Zhi Yuan Chen, R. Dewey Lee, Brian T. Scully

Faculty Publications

Throughout the world, aflatoxin contamination is considered one of the most serious food safety issues concerning health. Chronic problems with preharvest aflatoxin contamination occur in the southern US, and are particularly troublesome in corn, peanut, cottonseed, and tree nuts. Drought stress is a major factor to contribute to preharvest aflatoxin contamination. Recent studies have demonstrated higher concentration of defense or stress-related proteins in corn kernels of resistant genotypes compared with susceptible genotypes, suggesting that preharvest field condition (drought or not drought) influences gene expression differently in different genotypes resulting in different levels of "end products": PR(pathogenesis-related) proteins in the mature …

Into The Imagined Forest: A 2000-Year Retrospective Of The German Woods, Richard Hacken

Faculty Publications

In a "House of Learning" lecture in the Harold B. Lee Library in October, 2008, Richard Hacken gave this presentation, a combination of text and images. Coming from the history of ideas, this retrospective of the German woods looked at historical, linguistic, artistic, philosophical, political, literary, cultural, and of course botanical aspects of the German forest. In summary, five major forest themes arise from Germans imagining their own German woods: (1) taming the external and internal wilderness; (2) establishing social justice; (3) advocating national unity; (4) maintaining a sense of the sacred; and (5) encouraging ecological awareness.
