Habitat Use Patterns Within The Home Range Of Pygmy Rabbits (Brachylagus Idahoensis) In Southeastern Idaho, Laura T. Heady, John W. Laundré Nov 2005

Habitat Use Patterns Within The Home Range Of Pygmy Rabbits (Brachylagus Idahoensis) In Southeastern Idaho, Laura T. Heady, John W. Laundré

Western North American Naturalist

Pygmy rabbits (Brachylagus idahoensis) are a small sagebrush (Artemisia tridentata) obligate lagomorph found within the Great Basin of northwestern United States. Because of its reliance on sagebrush, this species is thought to be experiencing a major range reduction as a result of loss of sagebrush habitat. To aid in conservation of this species, we need to better understand its use of the sagebrush environment. We estimated summer home range use patterns by relocating 5 radio-collared pygmy rabbits (3 females and 2 males) over a 24-hour cycle. We then compared soil texture, shrub density, height, and canopy …

Relationship Of Diurnal Habitat Use Of Native Stream Fishes Of The Eastern Great Basin To Presence Of Introduced Salmonids, Darren G. Olsen, Mark C. Belk Nov 2005

Relationship Of Diurnal Habitat Use Of Native Stream Fishes Of The Eastern Great Basin To Presence Of Introduced Salmonids, Darren G. Olsen, Mark C. Belk

Western North American Naturalist

Introduced brown trout, Salmo trutta, are common to many streams of western North America. However, the ecological interactions between brown trout and native stream fishes are not well understood, particularly the nature and extent of antipredator responses of native species. We examined the effects of brown trout presence on diurnal habitat use by 2 small native fishes at a mesohabitat scale (e.g., pool, riffle, run, backwater, etc.). Adult and juvenile southern leatherside chub (Lepidomeda aliciae, formerly Gila copei) and juvenile mountain sucker (Catostomus platyrhynchus) were located in main channel pools in the absence of …

Great Basin Summer Range Forage Quality: Do Plants Nutrients Meet Elk Requirements?, Jeffrey L. Beck, James M. Peek Nov 2005

Great Basin Summer Range Forage Quality: Do Plants Nutrients Meet Elk Requirements?, Jeffrey L. Beck, James M. Peek

Western North American Naturalist

Understanding the relative ability of forages to meet the needs of prime-age females, the productive component of elk (Cervus elaphus) populations, is necessary to decipher reasons for declines and potential for population growth. Information on forage nutrient dynamics for elk on Great Basin summer–fall ranges is lacking. Our primary objectives were to estimate nutrient levels in common elk forage species in northeastern Nevada at 3 time periods and evaluate whether nutrient levels met good requirements for lactating cow elk at time periods across summers. We compared crude protein, digestible energy, and macromineral levels in 2 forbs, 6 grasses, …

Real-Time Motion Transition By Example, Cameron Quinn Egbert Nov 2005

Real-Time Motion Transition By Example, Cameron Quinn Egbert

Theses and Dissertations

Motion transitioning is a common task in real-time applications such as games. While most character motions can be created a priori using motion capture or hand animation, transitions between these motions must be created by an animation system at runtime. Because of this requirement, it is often difficult to create a transition that preserves the feel that the actor or animator has put into the motion. An additional difficulty is that transitions must be created in real-time. This paper provides a method of creating motion transitions that is both computationally feasible for interactive speeds, and preserves the feel of the …

Fremont Storage And Mobility: Changing Forms Through Time, David T. Yoder Nov 2005

Fremont Storage And Mobility: Changing Forms Through Time, David T. Yoder

Theses and Dissertations

Groups of agriculturalist/hunter-gatherers known as the Fremont inhabited the eastern Great Basin and Colorado Plateau from roughly A.D. 1-A.D. 1350 (Madsen 1989). Fremont groups used differing storage strategies through time and across space. Storage strategies included on-site and off-site storage facilities which were constructed above and/or below-ground. These forms of storage occurred at different frequencies and times throughout the Fremont's 1350 year time span. Researchers (Binford 1980, 1990; Keeley 1988; Soffer 1989; Testart 1982; Wills 1992; Young 1996) using examples from various parts of the world have noted a correlation between the degree of residential mobility and the use of …

Effectiveness Of Story Enactments Versus Art Projects In Facilitating Preschool Children's Story Comprehension, Jennifer Ann Johnson Nov 2005

Effectiveness Of Story Enactments Versus Art Projects In Facilitating Preschool Children's Story Comprehension, Jennifer Ann Johnson

Theses and Dissertations

The purpose of this study was twofold: (a) to compare preschool children's comprehension of a story after either enacting the story or participating in an art project, and (b) to qualitatively describe the children's interactions during the more interactive story enactment instruction. Twenty children from two Head Start classrooms were told the stories as a class, and then participated in either an art project (AP) or story enactment (SE) in small groups. The children in each classroom each heard three stories followed by the AP condition, and three followed by the SE condition. The children's comprehension of the story was …

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 …

Total Syntheses Of (+)-Geldanamycin, (-)-Ragaglitazar, And (+)-Kurasoin A And Phase-Transfer-Catalyzed Asymmetric Alkylation, Erik J. Hicken Nov 2005

Total Syntheses Of (+)-Geldanamycin, (-)-Ragaglitazar, And (+)-Kurasoin A And Phase-Transfer-Catalyzed Asymmetric Alkylation, Erik J. Hicken

Theses and Dissertations

Geldanamycin possesses various biological activities as seen in the NCI 60 cell line panel (13 nM avg., 70 nM SKBr-3 cells). The predominant mode of action providing these unique results arises from the ability of geldanamycin (GA) to bind to the chaperone heat shock protein 90 (Hsp90). Despite its complicated functionality, the first total synthesis of GA was accomplished, which included two new reactions developed specifically to address the stereochemical features. The final step in the synthesis of GA was a demethylation-oxidation sequence to generate the desired para-quinone. This step could only be accomplished with HNO3/AcOH, producing GA in …

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 Oct 2005

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 …

Generation Of Biomarkers From Anthrax Spores By Catalysis And Analytical Pyrolysis, Phillip R. Smith Aug 2005

Generation Of Biomarkers From Anthrax Spores By Catalysis And Analytical Pyrolysis, Phillip R. Smith

Theses and Dissertations

Anthrax spores, in weaponized form, are dangerous biological warfare agents. Handheld technology for the rapid detection of anthrax is greatly needed to improve national security. Methods to detect anthrax spores are diverse, with most taking at least an hour for positive identification. A viable option for rapid detection is analytical pyrolysis (AP), which produces chemicals containing taxonomical information (biomarkers). AP methods are reviewed and critically analyzed to show that reproducible detection of anthrax spores in a rapid manner (< 5 min) with a handheld device is not currently possible. A promising alternative to AP is the use of a catalyst to produce biomarkers from anthrax spores with improved selectivity and reproducibility. Catalytic materials having promise for this include platinum, nickel, and superacids. Experiments evaluating several of these materials are described. A biomarker mass spectral library was created, based on information available in the scientific literature, to facilitate analysis and identification of the biomarkers produced experimentally. The RAMFAC algorithm was used to deconvolute chromatographic peaks to produce clean mass spectra and match them against entries in the biomarker library. While the library is not complete, its use with the RAMFAC algorithm enabled detection of many important biomarkers in experiments involving catalytic breakdown of anthrax spores. Experimental results from preliminary tests of several catalysts are presented and discussed. Addition of catalysts in the form of platinum nanoclusters and superacids to bacterial spores in a commercial pyrolyzer effected an increase in the amount of biomarkers produced at mild conditions over traditional pyrolysis methods. Electroformed nickel mesh, on the other hand, demonstrated low catalytic activity for the production of biomarkers, likely due to poor contact of the spores with the mesh. Biomarkers similar to those published in the literature were observed, including dipicolinic acid, picolinic acid, propionamide, acetamide, diketopiperazines, fatty acids, furfuryl alcohol, and DNA bases. A statistically designed factorial study was used to determine the importance of temperature, spore loading, and nanocluster loading on the production of three important biomarkers. The relative importance of these variables differs for each of the three important biomarkers, suggesting they are produced by different reaction mechanisms.

Combating The Banality Of Evil: Portrayals Of The Literary Female Villain In Gã¼Nter Grass's Danziger Trilogie And Novella, Im Krebsgang., Joseph Ephraim Baumgarten Aug 2005

Combating The Banality Of Evil: Portrayals Of The Literary Female Villain In Gã¼Nter Grass's Danziger Trilogie And Novella, Im Krebsgang., Joseph Ephraim Baumgarten

Theses and Dissertations

In Günter Grass's Danzig Trilogy and novella, Im Krebsgang, an antagonistic female type makes a repeated appearance. She appears in the guise of Susi Kater and Luzie Rennwand in Die Blechtrommel, and as Tulla Pokriefke in the other works, Katz und Maus, Hundejahre, and Im Krebsgang. This antagonistic female type is not like other women in these works. A review of Le Deuxième Sexe by feminist Simone de Beauvoir reveals several crucial components contributing to woman's position in society. Most essentially, a woman's natural attributes and (dis)abilities and the conventions of society have enforced her historical submission to man. This …

Exploration Of Lip Shape Measures And Their Association With Tongue Contact Patterns, Jessica Lynn Wagner Aug 2005

Exploration Of Lip Shape Measures And Their Association With Tongue Contact Patterns, Jessica Lynn Wagner

Theses and Dissertations

A variety of tools and techniques have been developed to measure the movements of the vocal tract, specifically of the tongue and lips. In recent years, computer technology has allowed for extensive exploration of these precise movements and for the development of speech recognition systems. However, there has been relatively little work on the combination of visible facial movements and internal articulatory activity. In this study, two different technologies were used to explore the internal and external movements of speech production in eight speakers: palatometry quantified tongue contact patterns and computerized video image analysis was used to derive lip shape …

Archaeology, Relics, And Book Of Mormon Belief, John E. Clark Jul 2005

Archaeology, Relics, And Book Of Mormon Belief, John E. Clark

Journal of Book of Mormon Studies

Archaeology has much to offer as a scientific means of gathering independent evidence of the Book of Mormon’s authenticity. But one must look in the right place. A cautionary tale is the failed Cluff expedition of 1900, which, assuming a “hemispheric model” of Book of Mormon geography, traveled from Provo as far as Colombia looking for the city Zarahemla. Yet in 1842 the Times and Seasons (under Joseph Smith’s editorship) had printed excerpts from a popular book on Mesoamerican archaeology that demonstrated a surprisingly high level of civilization, implying that Nephite lands did not extend into South America, thus supporting …

Evaluating Lek Occupancy Of Greater Sage-Grouse In Relation To Landscape Cultivation In The Dakotas, Joe T. Smith, Lester D. Flake, Kenneth F. Higgins, Gerald D. Kobriger, Collin G. Homer Jul 2005

Evaluating Lek Occupancy Of Greater Sage-Grouse In Relation To Landscape Cultivation In The Dakotas, Joe T. Smith, Lester D. Flake, Kenneth F. Higgins, Gerald D. Kobriger, Collin G. Homer

Western North American Naturalist

Greater Sage-Grouse (Centrocercus urophasianus) have been declining in many states and provinces of North America, and North and South Dakota hold no exception to these declines. We studied effects of cultivated land on Greater Sage-Grouse lek abandonment in North and South Dakota. Landscape-level data were assessed using satellite imagery within a geographic information system. Comparisons were made of 1972–1976 and 1999–2000 percent cultivated and noncultivated land. These comparisons were made between land uses surrounding active leks versus inactive leks, active leks versus random locations, and abandoned regions versus active regions. The 1999–2000 imagery illustrated that percent cultivated land …

A Comprehensive Ecological Land Classification For Utah's West Desert, Neil E. West, Frank L. Dougher, Gerald S. Manis, R. Douglas Ramsey

Western North American Naturalist

Land managers and scientists need context in which to interpolate between or extrapolate beyond discrete field points in space and time. Ecological classification of land (ECL) is one way by which these relationships can be made. Until regional issues emerged and calls were made for ecosystem management (EM), each land management institution chose its own ECLs. The need for economic efficiency and the increasing availability of geographic information systems (GIS) compel the creation of a national ECL so that communication across ownership boundaries can occur. ECOMAP, an 8-level, top-down, nested, hierarchical, multivariable approach designed to solve this problem has been …
