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 …

Word-Formation As Creativity Within Productivity Constraints: Sociolinguistic Evidence, Don William Chapman, Pavol Stekauer, Slávka Tomaščíková, Štefan Franko

Faculty Publications

Productivity has been one of the central topics in the field of word-formation in recent decades. Heretofore, productivity has been mainly, if not solely, discussed in formal terms, such as which affixes can be used with which stems, the productivity of rival affixes, etc. Such a formal approach leaves out the speakers’ needs for creating new words. Accounting for speakers’ word-formation needs requires a re-evaluation of the notion of creativity. In our approach to word-formation, this notion emphasizes the active role of language users, reflecting the fact that, in each act of naming, there is more or less significant space …

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 …

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 …

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 …

The purpose of this study was to determine the effects of video modeling on skill acquisition in learning the golf swing. One-hundred-eight college students participated in this study. All participants were pre-tested via videotaping to determine initial skill level. The pre-test videotaping was analyzed using DartTrainer software. Each participant was randomly assigned to one of three groups (1) control (2) single-view or (3) multi-view. Participants in the control group viewed a compact disc (CD) with a putting demonstration repeated 40 times. The participants in the single-view group viewed a CD with a front view only demonstration repeated 40 times of …

Identification Of Proteins Involved In Chloroplast Dna Replication, Matthew G. Lassen

Theses and Dissertations

Chapter 1

Chloroplast nucleoids (ct-nucleoids) are DNA/protein complexes involved in compacting the chloroplast genome, and may play a role in regulating DNA replication. Ct-nucleoids were isolated from young soybean plants and separated by 2-D gel electrophoresis. Gel spots were excised and analyzed by MALDI-ToF mass spectrometry, resulting in several protein identifications. The proteins identified all have functions unrelated to DNA replication. While some of these proteins may be due to contamination, it is possible that some of these proteins are dual-functional, playing direct roles in the regulation of DNA replication.

Chapter 2

A 28 kDa soybean protein was isolated by …

Impact Of Microfinance Programs On Children's Education: Do The Gender Of The Borrower And The Delivery Model Matter?, Nathalie Holvoet

Journal of Microfinance / ESR Review

This article highlights the effects particular features of microfinance programs have on childhood education. Using data from a South India household survey, the article examines how microfinance impacts schooling and literacy, how credit enters the household, and who brings it in. Regression results show that, in the case of direct bank-borrower credit delivery, it does not matter whether credit enters the household through the mother or the father. However, large differences occur when mothers obtain credit through women's groups. Analysis indicates that combined financial and social-group intermediation leads to higher educational inputs and outputs, mainly for girls. Individual interviewis with …

Distribution Of Chemistry And Sexual Fecundity In The Lichenized-Fungi, Xanthoparmelia Cumberlandia And Xanthoparmelia Coloradoensis On Boulder Mountain, Aquarius Plateau, Ut, Heather Bird Jackson

Theses and Dissertations

Three aspects of Xanthoparmelia cumberlandia and Xanthoparmelia coloradoënsis populations found at two elevations are explored: clustering of secondary chemicals and the resulting implications for taxonomic distinctions, the usefulness of thallus size as an indirect measure of sexual fecundity, and the frequency of sexual reproduction.

First, we use clustering of 46 chemicals produced by X. cumberlandia and X. coloradoënsis to evaluate the adequacy of the current taxonomic distinction between them. Using principal components analysis and UPGMA, we find that the currently recognized species boundaries indicated by the presence of stictic acid in X. cumberlandia and salazinic acid in X. coloradoënsis are …

Microleasing: The Grameen Bank Experience, Asif Dowla

Journal of Microfinance / ESR Review

Grameen Bank was the first microfinance institution (MFI) to introduce microleasing on a large scale. This paper provides a preliminary evaluation of Grameen's leasing program. Instead of providing a full-fledged impact assessment study, we examine the terms and conditions of the leasing program and evaluate its success in terms of outreach, repayment rate, and asset ownership.Analysis of program level data shows that the program is successful in terms of outreach and repayment performance. Through the program, poor men and women have become owners of power tillers, power looms, shallow machines, cellular phones, and even computers. The success of leasing suggests …

Phosphorylation Of Skeletal Muscle Acetyl-Coa Carboxylase By Ampk Enhances Palmitoyl-Coa Inhibition, Dustin S. Rubink

Theses and Dissertations

Acetyl-CoA carboxylase (ACC) catalyzes the formation of malnoyl-CoA, which in turn controls the rate of fatty acid metabolism. ACC beta or 2 has been shown to be localized on the mitochondria in close proximity to carnintine palmitoyl transferase 1 (CPT-1), the enzyme responsible for the influx of acyl-CoA into the matrix where beta oxidation takes place. CPT-1 is inhibited by malonyl-CoA produced by ACC. It has been well documented that AMP activated kinase (AMPK) when activated phosphorylates and inactivates ACC. ACC is controlled allosterically by citrate, which activates, and by palmitoyl-COA, which inhibits. In this study, we asked the question, …

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 …

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 …

Density Effects On Growth, Survival And Diet Of June Sucker (Chasmistes Liorus): A Component Allee Effect In An Endangered Species., David Barrett Gonzalez

Theses and Dissertations

Density-dependence is considered one of the most important regulators of population growth, and it has been documented across a wide variety of species. Typically, population growth rate and components thereof decline with increasing density (i.e., negative density-dependence); however, in species that exhibit high population densities and social behavior, positive density-dependence (i.e., Allee effect) may occur at low density. June sucker, a federally endangered lake sucker endemic to Utah Lake, Utah, USA, occurred historically at high density, and it exhibits coordinated feeding behavior. These characteristics indicate a potential for the existence of an Allee effect at current low population densities. To …

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.

Effects Of Different Jumping Programs On Hip And Spine Bone Mineral Density In Pre-Menopausal Women, J. Eric Strong

Theses and Dissertations

Sixty premenopausal women (age 25-50) finished a 16 week randomized controlled trial looking at the effects of different jump programs on hip and spine bone mineral density (BMD). Subjects were randomly assigned to a control group or one of two jumping groups. The Jump 10 group performed 10 jumps with 30 seconds of rest between jumps, twice daily, while the Jump 20 group performed the same protocol but with 20 jumps. At 8 weeks, BMD percent change (%Δ) at the hip was significantly different among groups when age, weight change, and subject compliance were simultaneously adjusted. In particular, the Jump …

Introduction: The Swiss Protestant Reformation

Swiss American Historical Society Review

On November 28th , 2002 the innocent family Lieu awoke to begin another day of prayer, devotion and work in their hometown of Danane in the Ivory Coast, West Africa. However, at 9 AM gunfire erupted and rebel forces began dropping bombs on the town, announcing that the current civil war in the Ivory Coast had reached Danane, terrifying the citizens and traumatizing the Lieu family to such an extent that they and many of their neighbors resolved to flee, with literally just the shirts on their backs, into the jungle. For months they lived like animals in the wilderness …

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 …

The Centipede Genus Arthrorhabdus Pocock, 1891, In The Western Hemisphere: Potential Occurrence Of A. Pygmaeus (Pocock, 1895) In Belize (Scolopendromorpha: Scolopendridae: Scolopendrinae), Rowland M. Shelley, Amazonas Chagas-Júnior

Western North American Naturalist

The scolopendrid centipede genus Arthrorhabdus Pocock, 1891, comprises 6 species: A. formosus Pocock, 1891, the type species, occurring in southern Africa (Mpumalanga, Free State, Western and Northern Cape Provinces, South Africa, and southern Namibia); A. somalus Manfredi, 1933, in Somalia and Yemen; A. jonesii Verhoeff, 1938, from southern India (Kerala Province); A. mjobergi Kraepelin, 1916, and A. paucispinus Koch, 1984, in Australia (Western and South Australia, Northern Territory, and Queensland); and A. pygmaeus (Pocock, 1895), in the south central and southwestern United States, Mexico, and, potentially, Belize. This sporadic occurrence suggests that the genus is polyphyletic, and the monotypic synonym, …

Evaluating The Geographic Distribution Of Plants In Utah From The Atlas Of Vascular Plants Of Utah, R. Douglas Ramsey, Leila Shultz

Western North American Naturalist

Locations of 73,219 vascular plant vouchers representing 2438 species were digitized from the Atlas of the Vascular Plants of Utah (Albee et al. 1988). Source maps consist of 1:6,000,000-scale shaded relief maps of Utah with points representing collection locations by species. Location points, representing 1 or more specimens, were transposed onto these maps from the approximately 400,000 herbarium records of 3 major universities and federal land management agencies. These source maps were digitized into an ARC/Info^TM database in order to reproduce the atlas in digital form. Analysis of all locations revealed a mapping bias of the original authors to …

A Relocation Technique For Black-Tailed Prairie Dogs, Kelly A. Roe, Christopher M. Roe

Western North American Naturalist

Relocations of black-tailed prairie dogs have occurred both to save individual prairie dogs from urban development and to reestablish populations that have been extirpated. Unfortunately, however, many past relocation efforts rarely exceeded 40% retention. Many factors have contributed to very low retention rates in past relocation efforts including lack of (1) suitable habitat, (2) proper artificial burrow systems, (3) aboveground acclimation cages or pens, and (4) skilled people conducting the relocations. In an attempt to increase prairie dog relocation success, we developed techniques that are easy to implement, promote high retention, and effectively conserve labor, financial resources, and prairie dog …

Marmot Distribution And Habitat Associations In The Great Basin, Chris H. Floyd

Western North American Naturalist

In this study I describe the distribution and habitat associations of yellow-bellied marmots (Marmota flaviventris) in the Great Basin, compare my findings with those of E.R. Hall during his 1929–1936 survey and later surveys, and discuss potential reasons for changes in marmot distribution over time. I found 62 marmot burrow sites in 18 mountain ranges, mostly in rocky meadows situated on well-drained slopes between 2100 m and 3000 m elevation. Marmots were generally found near burrows dug within talus slopes, talus-like rock piles, or clusters of massive boulders. Oceanspray (Holodiscus discolor) was the shrub most commonly …

Dynamics Of A Dwarf Bear-Poppy (Arctomecon Humilis) Population Over A Sixteen-Year Period, K. T. Harper, Renée Van Buren

Western North American Naturalist

A population of the dwarf bear-poppy (Arctomecon humilis Coville, Papaveraceae) at Red Bluff, Washington County, Utah, was monitored twice annually between 1987 and 2002. This is a narrowly endemic, gypsophilous species that has been formally listed as endangered since 1979. During the 16 years of observation, density of this species has fluctuated between 3 and 1336 individuals on the 0.07-ha monitoring plot. Moderate to large recruitments of seedlings occurred in 1992, 1995, and 2001. Seedling recruitments from a large, long-lived seed bank are triggered by abundant precipitation during the February–April period. At least 5.0 cm of rainfall is required …

Native Plant Community Composition And Genetic Diversity Associated With Long-Term Weed Invasions, Brian A. Mealor, Ann L. Hild, Nancy L. Shaw

Western North American Naturalist

Many studies have assessed genetic changes in exotic plant species in their native and introduced ranges, but none have focused on genetic variation in native plant species in response to exotic invasion. We examine characteristics of native plant communities within and outside old (>25 year) invasions of Acroptilon repens (Russian knapweed) and Cardaria draba (hoary cress). We also document genetic variability of 4 native grass populations (Hesperostipa comata [needle and thread], Achnatherum hymenoides [Indian ricegrass], Sporobolus airoides [alkali sacaton], and Poa secunda [Sandberg bluegrass]) from 2 areas: adjacent to and within weed invasions. Native plant species richness and …
