The Epistle To The Hebrews And Patron-Client Relationships: Toward A Missiological Appropriation, Cheryl D. Doss

Faculty Publications

Missionaries in cultures where patron-client relationships are common can find their participation in such relationships difficult. Recent New Testament scholarship has illuminated the patron-client relationships implicitly described in the epistle to the Hebrews. Utilizing this scholarship, this article explores the patron-client relationships illustrated in the epistle to the Hebrews seeking biblical principles to guide missionary life and practice.

Genetic Variation In Ustilago Bullata: Molecular Genetic Markers And Virulence On Bromus Tectorum Host Lines, Mikel Stevens, Daniel J. Fairbanks, Susan E. Meyer, David L. Nelson, Suzette Clement, Jennifer Waters

Faculty Publications

The pathogen Ustilago bullata often causes epidemic levels of head smut disease in Intermountain populations of the inbreeding annual grass Bromus tectorum. We examined patterns of genetic variation for virulence and for amplified fragment length polymorphism (AFLP) markers in four U. bullata populations on B. tectorum in northern Utah and southern Nevada. Patterns of disease incidence generally supported a genefor-gene model for virulence and resistance in this pathosystem. Most host lines were susceptible to most or all paired isolates included in cross-inoculation tests, but we found evidence for the existence of four avirulence genes. Host lines with alleles conferring resistance …

Seasonal Acceptance Of Fourwing Saltbush By Sheep When Crested Wheatgrass Is The Alternative, Val J. Anderson, R. D. Horrocks, Christine W. Royer, Stephen B. Monsen

Faculty Publications

Many sagebrush-grass ranges have been seeded to crested wheatgrass [Agropyron desertorum (Fischer ex Link) Shultes]. These ranges are generally nutritionally inadequate for sheep (Ovis aries L.), except for short grazing periods in the spring and fall. To increase production and diversity, particularly crude protein for late-season grazing, fourwing saltbush [Atriplex canescens (Pursch.) Nutt.] was planted in an existing stand of crested wheatgrass. Quantification of sheep forage preferences on these improved ranges aids in determining the length of the grazing season and the extent to which shrubs provide the supplemental nutrition required. This seasonal grazing study was conducted on a characteristic …

Five Powerful Practices For Using Technology To Enhance Teaching And Learning In Higher Education, Charles R. Graham, Richard E. West

Faculty Publications

This presentation reports the findings from our investigation of the professors designated as the most innovative users of technology at our university. After seeking nominations from department heads, we selected thirty-five of the most successful and innovative professors as case studies. After interviewing these cases, and in some instances observing their classes, we identified five major patterns that represented the positive impacts technology was having on their instruction. These patterns were evident in several cases across many different disciplines, indicating they might be generalizable to many different situations and contexts. In our interviews, we identified what technologies these professors were …

"That Could Happen": Nature Writing, The Nature Fakers, And A Rhetoric Of Assent, David Thomas Sumner

Faculty Publications

Much has been made about the relationship between nature writing and science. The foundation of the genre is empirical observation of the more-than-human world. That’s not the whole of it, however. Because of the pairing of empiricism and other human experience, readers come to the genre with certain assumptions: they assume the text will tell them something independently verifiable about the object world--something they could see, hear, or touch if they were in the same location at the same time. They assume they are reading nonfiction, and for most readers, that distinction is important. Readers also come to nature writing …

Dietary Isoflavones Alter Regulatory Behaviors, Metabolic Hormones And Neuroendocrine Function In Long-Evans Male Rats, Edwin D. Lephart, James P. Proter, Lihong H. Bu, Trent D. Lund, Kenneth Setchell, Gina Ramoz, William R. Crowley

Faculty Publications

Phytoestrogens derived from soy foods (or isoflavones) have received prevalent usage due to their 'health benefits' of decreasing: a) age-related diseases, b) hormone-dependent cancers and c) postmenopausal symptoms. However, little is known about the influence of dietary phytoestrogens on regulatory behaviors, such as food and water intake, metabolic hormones and neuroendocrine parameters. This study examined important hormonal and metabolic health issues by testing the hypotheses that dietary soy-derived isoflavones influence: 1) body weight and adipose deposition, 2) food and water intake, 3) metabolic hormones (i.e., leptin, insulin, T3 and glucose levels), 4) brain neuropeptide Y (NPY) levels, 5) heat production …

Fragile Fiber3, An Arabidopsis Gene Encoding A Type Ii Inositol Polyphosphate 5-Phosphatase, Is Required For Secondary Wall Synthesis And Actin Organization In Fiber Cells, Ruiqin Zhong, David H. Burk, W. Herbert Morrison, Zheng Hua Ye

Faculty Publications

Type II inositol polyphosphate 5-phosphatases (5PTases) in yeast and animals have been known to regulate the level of phosphoinositides and thereby influence various cellular activities, such as vesicle trafficking and actin organization. In plants, little is known about the phosphatases involved in hydrolysis of phosphoinositides, and roles of type II 5PTases in plant cellular functions have not yet been characterized. In this study, we demonstrate that the FRAGILE FIBER3 (FRA3) gene of Arabidopsis thaliana, which encodes a type II 5PTase, plays an essential role in the secondary wall synthesis in fiber cells and xylem vessels. The fra3 mutations caused a …

Neglected Taxonomy Of Rare Desert Fishes: Congruent Evidence For Two Species Of Leatherside Chub, Jerald B. Johnson, Thomas E. Dowling, Mark C. Belk

Faculty Publications

Conservation biologists rely heavily on taxonomy to set the scope for biological monitoring and recovery planning of rare or threatened species. Yet, taxonomic boundaries are seldom evaluated as falsifiable hypotheses that can be statistically tested. Here, we examine species boundaries in leatherside chub (Teleostei, Cyprinidae), an imperiled desert fish native to the Bonneville Basin and upper Snake River drainages of western North America. Recent molecular data hint that this fish could be composed of two distinct taxa that are geographically separated into northern and southern species. To formally test this hypothesis, we evaluated leatherside chub using several different categories of …

Images Of Migration And Change In The German-Language Poetry Of Galsan Tschinag, Richard Hacken

Faculty Publications

Presented March 25, 2004, at the European presentation for Migrations in Society, Culture, and the Library held in Paris. Migration in the works of Galsan Tschinag could be discussed on a number of levels. The first is an actual geographic migration documented in the published diaries of Tschinag. The next level of migration could be a linguistic migration of ideas and words from Tschinag's native Tuvan language which has no written script sometimes to Mongolian, but most often to German. The main focus is on the diverse images of migration in his German-language poetry, often illustrating transmigration of spirits between …

The Decline Of Covenant In Early Christian Thought, Noel B. Reynolds

Faculty Publications

While many LDS attempts to describe or explain the transformation of the Christian movement and its teachings in the early centuries in terms of an accommodation to Greek philosophy, this paper focuses on the first two Christian centuries and the early elimination of covenant thinking and practice that may have opened the door to Greek thought.

Three Distinct Suppressors Of Rna Silencing Encoded By A 20-Kb Viral Rna Genome, Rui Lu, Alexey Folimonov, Michael Shintaku, Wan Xiang Li, Bryce W. Falk, William O. Dawson, Shou Wei Ding

Faculty Publications

Viral infection in both plant and invertebrate hosts requires a virus-encoded function to block the RNA silencing antiviral defense. Here, we report the identification and characterization of three distinct suppressors of RNA silencing encoded by the ≈20-kb plus-strand RNA genome of citrus tristeza virus (CTV). When introduced by genetic crosses into plants carrying a silencing transgene, both p20 and p23, but not coat protein (CP), restored expression of the transgene. Although none of the CTV proteins prevented DNA methylation of the transgene, export of the silencing signal (capable of mediating intercellular silencing spread) was detected only from the F 1 …

The Situational Character: A Critical Realist Perspective On The Human Animal, Jon Hanson, David Yosifon

Faculty Publications

This Article is dedicated to retiring the now-dominant "rational actor" model of human agency, together with its numerous "dispositionist" cohorts, and replacing them with a new conception of human agency that the authors call the "situational character." This is a key installment of a larger project recently introduced in an article titled

The Situation: An Introduction to the Situational Character, Critical Realism, Power Economics, and Deep Capture. That introductory article adumbrated, often in broad stroke, the central premises and some basic conclusions of a new approach to legal theory and policy analysis. This Article provides a more complete version of …

High-Threshold, Kv3-Like Potassium Currents In Magnocellular Neurosecretory Neurons And Their Role In Spike Repolarization, Talent Shevchenko, Ryoichi Teruyama, William E. Armstrong

Faculty Publications

We identified Kv3-like high-threshold K+ currents in hypothalamic supraoptic neurons using whole cell recordings in hypothalamic slices and in acutely dissociated neurons. Tetraethylammonium (TEA)-sensitive currents (TEA) evoked from -50 I/V were characterized by a large component that inactivated in 10-30 ms, and a smaller, persistent component that inactivated in 1-2 s. UV relations in dissociated neurons revealed TEA-subtracted currents with a slope and voltage dependency consistent with the presence of Kv3-like channels. In slices, tests with 0.01-0.7 mM TEA produced an IC50 of 200-300 nM for both fast and persistent currents. The fast transient current was similar to currents associated …

Relaxation To Native Conformation Of A Bond-Fluctuating Protein Chain With Hydrophobic And Polar Nodes, Johan Bjursell, Ras B. Pandey

Faculty Publications

The conformation and dynamics of a protein chain with hydrophobic and polar nodes are examined by the bond-fluctuation model using Monte Carlo simulations on a cubic lattice. The minimal (nearest neighbor) interaction leads to standard (self-avoiding walk) conformation, i.e., the scaling of the radius of gyration R_g with the molecular weight N R_g ∝ N^γ with γ ≃ 3/5/ Specific interactions with longer range and higher strength are needed to approach the native globular conformations with γ < 3/5. Relaxation into the globular ground state shows a weak power-law decay, i.e., R_g ∝ t^-α, α ~ 0.06-0.12.

The Mormon Hive: A Study Of The Bee And Beehive Symbols In Nineteenth Century Mormon Culture, J. Michael Hunter

Faculty Publications

From antiquity to the middle of the eighteenth century, humans used the bee and beehive symbols to represent monarchy. Political and social changes resulted in a reinterpretation of the bee and beehive symbols during the eighteenth century. Republicans ignored the royalist associations of bees and beehives, and used them to represent values of the new republicanism. In nineteenth-century America, the Mormons, members of The Church of Jesus Christ of Latter-day Saints, encountered the bee and beehive symbols while participating in the rites of Freemasonry. In the nineteenth century, Mormons used the bee and beehive symbols to represent the Kingdom of …

Membrane Lipid Biosynthesis In Chlamydomonas Reinhardtii: Ethanolaminephosphotransferase Is Capable Of Synthesizing Both Phosphatidylcholine And Phosphatidylethanolamine, Wenyu Yang, James V. Moroney, Thomas S. Moore

Faculty Publications

Phosphatidylethanolamine, but not phosphatidylcholine, is found in Chlamydomonas reinhardtii. A cDNA coding for diacylglycerol: CDP-ethanolamine ethanolaminephosphotransferase (EPT) was cloned from C. reinhardtii. The C. reinhardtii EPT appears phylogenetically more similar to mammalian aminoalcoholphosphotransferases than to those of yeast and the least close to those of plants. Similar membrane topography was found between the C. reinhardtii EPT and the aminoalcoholphosphotransferases from mammals, yeast, and plants. A yeast mutant deficient in both cholinephosphotransferase and ethanolaminephosphotransferase was complemented by the C. reinhardtii EPT gene. Enzymatic assays of C. reinhardtii EPT from the complemented yeast microsomes demonstrated that the C. reinhardtii EPT synthesized both …

Tropospheric Ozone In Louisiana And Synoptic Circulation, Robert Rohli

Faculty Publications

Abstract Tropospheric ozone (O3) is a pollutant of increasing concern in many urban areas in the United States. There is an increasing need to understand the geographical and meteorological properties associated with O3, particularly because of the changing criteria that are being implemented by the U.S. Environmental Protection Agency to monitor O3. This research examines the relationship between O3 mixing ratios in Louisiana and surface and low-tropospheric synoptic circulation patterns. Results suggest that local conditions and synoptic influences are both important in determining the behavior of observed O3 in Louisiana during this period in which “exceedance” frequencies decreased until 2000–01, …

A Brief Exploration Of Space: Some Observations On Law School Architecture, Robert H. Jerry Ii

Faculty Publications

The costs and benefits of some architectural choices are immediately obvious, as in the case of disability accommodations. But other choices are less obvious, even when one does not attempt to predict how a design will function thirty or forty years hence. This is why having a skilled design team involved in developing the plan and executing it is so important.

Broken Scales: Obesity And Justice In America, Adam Benforado, Jon Hanson, David Yosifon

Faculty Publications

This Article is not so much about the scales we use to measure weight, but the scales we use to infer causation and assign responsibility-including the scales of justice. Ultimately, the problem we face is not obesity itself. Obesity is only a symptom of the problem. When scientists and public health experts point to various environmental agents-whether larger portion sizes, corn subsidies, video games, or urban sprawl-they, too, overlook the deeper source of our troubles. Our real problem is that we have an extremely difficult time seeing and understanding the role of unseen features in our environment and within us …

There are a number of issues facing those who wish to employ learning objects to facilitate learning. These issues are not, however, inherent in the component-based paradigm. The first section of this paper describes some of the most difficult issues to be resolved. In the second section, we present a model of the use of learning objects that is grounded in a object-based paradigm. In the third section, we describe the …

Semi-Autonomous Human-Uav Interfaces For Fixed-Wing Mini-Uavs, Randal Beard, Michael A. Goodrich, Morgan Quigley

Faculty Publications

Sponsorship: DARPA, AFOSR. We present several human-robot interfaces that support real-time control of a small semi-autonomous UAV. These interfaces are designed for searching tasks and other missions that typically do not have a precise predetermined flight plan. We present a detailed analysis of a PDA interface and describe how our other interfaces relate to this analysis. We then offer quantative and qualitative performance comparisons of the interfaces, as well as an analysis of their possible real-world applications.

Defining A Link With Asthma In Mice Congenitally Deficient In Eosinophils, James J. Lee, Dawn Dimina, Mi Mi P. Macias, Sergei I. Ochkur, Michael P. Mcgarry, Katie R. O'Neill, Cheryl Protheroe, Ralph Pero, Thanh Nguyen, Stephania A. Cormier, Elizabeth Lenkiewicz, Dana Colbert, Lisa Rinaldi, Steven J. Ackerman, Charles G. Irvin, Nancy A. Lee

Faculty Publications

Eosinophils are often dominant inflammatory cells present in the lungs of asthma patients. Nonetheless, the role of these leukocytes remains poorly understood. We have created a transgenic line of mice (PHIL) that are specifically devoid of eosinophils, but otherwise have a full complement of hematopoietically derived cells. Allergen challenge of PHIL mice demonstrated that eosinophils were required for pulmonary mucus accumulation and the airway hyperresponsiveness associated with asthma. The development of an eosinophi-less mouse now permits an unambiguous assessment of a number of human diseases that have been linked to this granulocyte, including allergic diseases, parasite infections, and tumorigenesis.

Sperm Cryopreservation Of A Live-Bearing Fish, The Platyfish Xiphophorus Couchianus, Changjiang Huang, Qiaoxiang Dong, Terrence R. Tiersch

Faculty Publications

The objectives of this study were to evaluate the effects of cryoprotectant, osmotic pressure, cooling rate, equilibration time, and sperm-to-extender ratio, as well as somatic relationships of body length, body weight, and testis weight to sperm density in the platyfish Xiphophorus couchianus. Sperm motility and survival duration after thawing were significantly different between cryopreservation with dimethyl sulfoxide (DMSO) and glycerol, with the highest motility at 10 min after thawing obtained with 14% glycerol. With subsequent use of 14% glycerol as cryoprotectant, the highest motility after thawing was observed with Hanks' balanced salt solution (HBSS) across a range of 240-300 mOsm/kg. …

Test Of The Mechanotactile Hypothesis: Neuromast Morphology And Response Dynamics Of Mechanosensory Lateral Line Primary Afferents In The Stingray, Karen P. Maruska, Timothy C. Tricas

Faculty Publications

The mechanotactile hypothesis proposes that ventral non-pored lateral line canals in the stingray function to facilitate localization of prey that contact the skin during benthic feeding. This study used comparative neurophysiological and morphological techniques to test whether ventral non-pored canals encode the velocity of skin movements, and show other adaptations that may enhance detection of tactile stimuli from their prey. Resting discharge rate of lateral line primary afferent neurons was lower among units from ventral than dorsal canal groups. The ventral non-pored canals had a higher proportion of silent units (31%) than either ventral (3%) or dorsal (13%) pored canals, …

The Chlamydomonas Reinhardtii Proteins Ccp1 And Ccp2 Are Required For Long-Term Growth, But Are Not Necessary For Efficient Photosynthesis, In A Low-Co2 Environment, Steve V. Pollock, Davey L. Prout, Ashley C. Godfrey, Stephane D. Lemaire, James V. Moroney

Faculty Publications

The unicellular green alga Chlamydomonas reinhardtii acclimates to a low-CO2 environment by modifying the expression of a number of messages. Many of the genes that increase in abundance during acclimation to low-CO2 are under the control of the putative transcription factor Cia5. C. reinhardtii mutants null for cia5 do not express several of the known low-CO2 inducible genes and do not grow in a low-CO2 environment. Two of the genes under the control of Cia5, Ccp1 and Ccp2, encode polypeptides that are localized to the chloroplast envelope and have a high degree of similarity to members of the mitochondrial carrier …

Pharmacokinetics Of Once-Daily Amikacin In Healthy Foals And Therapeutic Drug Monitoring In Hospitalized Equine Neonates, Erica Paige Bucki, Steeve Giguère, Margo Macpherson, Rachel E. Davis

The objectives of this study were to investigate the pharmacokinetics of once-daily amikacin in healthy neonates, to determine amikacin concentrations in hospitalized foals, and to determine the minimum inhibitory concentrations (MICs) of amikacin against gram-negative isolates from blood cultures in septic foals. Median half-life, clearance, and volume of distribution of amikacin in healthy 2- to 3-day-old foals after administration of an intravenous bolus of amikacin (25 mg/kg) were 5.07 hours (4.86-5.45 hours), 1.82 mL/min/kg (1.35-1.97 mL/min/kg), and 0.785 L/kg (0.638-0.862 L/kg), respectively. Statistically significant (P or = 3 microg/mL between the 2 groups. An initial dose at 25 mg/kg is …

Testing Species Boundaries In An Ancient Species Complex With Deep Phylogeographic History: Genus Xantusia (Squamata: Xantusiidae), Keith A. Crandall, Elizabeth A. Sinclair, Robert L. Bezy, Kathryn Bolles, Jose L. Camarillo, Jack W. Sites

Faculty Publications

Identification of species in natural populations has recently received increased attention with a number of investigators proposing rigorous methods for species delimitation. Morphologically conservative species (or species complexes) with deep phylogenetic histories (and limited gene flow) are likely to pose particular problems when attempting to delimit species, yet this is crucial to comparative studies of the geography of speciation. We apply two methods of species delimitation to an ancient group of lizards (genus Xantusia) that occur throughout southwestern North America. Mitochondrial cytochrome b and nicotinamide adenine dinucleotide dehydrogenase subunit 4 gene sequences were generated from samples taken throughout the geographic …
