Participational Agency, Stephen C. Yanchar Sep 2011

Participational Agency, Stephen C. Yanchar

Faculty Publications

Participational agency is presented as a conceptual account of human action, volition, and possibility. Rooted in hermeneutic and narrative traditions, this view differs from other theorizing about agency (and most psychological theorizing in general) in that it makes no effort to explain human action by virtue of reified constructs. As an alternative to traditional theorizing in this area, participational agency is defined as meaningful engagement in the world and treats the experienced meaningfulness of practical human activity as its central feature. The concept of meaningful engagement is clarified through the presentation of four related themes—situated participation, existential concern, dispositional action, …

Foreign Language Houses: Identities In Transition, Wendy Baker, Jennifer Brown, Dan P. Dewey, Rob A. Martinsen

Faculty Publications

This study examined the lived experience of students participating in foreign language houses to improve their skills in Russian, French, or Japanese. American students residing in apartments with other language learners and a nativespeaking resident facilitator were required to speak with one another exclusively in the target language and participate in activities such as preparing and eating dinner together. Data sources for the study included interviews, observations, and video recordings. The data, which were analyzed qualitatively, revealed that the central experience of living in the foreign language house was the creation of a livable community and that use of the …


A Preliminary Report On Disordered Speech With Deep Brain Stimulation In Individuals With Parkinson's Disease, Christopher Dromey, Suzy Bjarnason Aug 2011

A Preliminary Report On Disordered Speech With Deep Brain Stimulation In Individuals With Parkinson's Disease, Christopher Dromey, Suzy Bjarnason

Faculty Publications

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has proven effective in treating the major motor symptoms of advanced Parkinson's disease (PD). The aim of this study was to learn which laryngeal and articulatory acoustic features changed in patients who were reported to have worse speech with stimulation. Six volunteers with PD who had bilateral STN electrodes were recorded with DBS turned on or off. Perceptual ratings reflected poorer speech performance with DBS on. Acoustic measures of articulation (corner vowel formants, diphthong slopes, and a spirantization index) and phonation (perturbation, long-term average spectrum) as well as verbal fluency scores …


Natural Polyploidization Within Tetraploid And Hexaploid Populations Of The Desert Shrub Atriplex Confertifolia, Stewart C. Sanderson Aug 2011

Natural Polyploidization Within Tetraploid And Hexaploid Populations Of The Desert Shrub Atriplex Confertifolia, Stewart C. Sanderson

Western North American Naturalist

Shadscale (Atriplex confertifolia) is a wind-pollinated dioecious shrub of western North America with an unusual development of apparently autoploid races, showing all even ploidy levels from 2x to 12x (base x = 9). Of these, tetraploid races are the most frequently encountered, with octoploids the next most common, and hexaploids being much less common. In this study, the occurrence of neopolyploid individuals within tetraploid and hexaploid populations of shadscale was examined at natural sites in order to investigate the pathways by which octoploids may be formed and to find a possible explanation for the predominance of octoploids over …


A Reconnaissance Of Small Mammal Communities In Garland And Government Prairies, Arizona, Joseph L. Ganey, Carol L. Chambers Aug 2011

A Reconnaissance Of Small Mammal Communities In Garland And Government Prairies, Arizona, Joseph L. Ganey, Carol L. Chambers

Western North American Naturalist

Small mammals play key ecological roles in grassland ecosystems, yet little is known regarding small mammal communities in large (>50 km2), high-elevation prairies embedded in ponderosa pine (Pinus ponderosa) forests in north central Arizona. To provide information on community composition and habitat relationships, we live-trapped small mammals on 6 transects in 2 prairies in 2008. We captured 78 individuals in 5501 trap occasions. Capture rates were low and varied widely among transects. Community composition was simple, with only 3 species of small mammals captured. In order of relative abundance, these species were deer mouse ( …


Maternal Investment By Yellowstone Pronghorn Following Winter Habitat Deterioration, Kerey K. Barnowe-Meyer, P. J. White, John A. Byers Aug 2011

Maternal Investment By Yellowstone Pronghorn Following Winter Habitat Deterioration, Kerey K. Barnowe-Meyer, P. J. White, John A. Byers

Western North American Naturalist

Spring and summer–autumn nutrition are the prime determinants of reproductive investment in most largeherbivore populations, though winter severity is known to affect reproductive rates in some situations. To evaluate the effects of a long-term decline in winter habitat quality, a diet shift away from sagebrush (Artemisia spp.) during winter, and differential habitat selection during spring–autumn on pronghorn (Antilocapra americana) reproduction, we assessed female and fawn condition, maternal investment, and early fawn survival in migrant and nonmigrant portions of the Yellowstone pronghorn population in Montana and Wyoming during 1999–2001. Mean female mass at capture in late winter (46.81 …


Distribution Records And Comments On Fleas In Southwestern South Dakota, Omer R. Larson, Steven G. Platt, Zannita Fast Horse, Thomas R. Rainwater, Stanlee M. Miller Aug 2011

Distribution Records And Comments On Fleas In Southwestern South Dakota, Omer R. Larson, Steven G. Platt, Zannita Fast Horse, Thomas R. Rainwater, Stanlee M. Miller

Western North American Naturalist

From October 2003 through April 2006, we collected 565 fleas incidental to a distribution survey of mammals in southwestern South Dakota. Sixty-one specimens, representing 18 species of mammals, possessed 20 species of fleas. The geographic distributions of these flea species revealed 8 new records for the Black Hills and its adjacent grasslands. Four species—Megarthroglossus divisus, Stenoponia americana, Odontopsyllus dentatus, and Amaradix euphorbi—constitute new records for South Dakota, thus increasing the state’s known flea fauna to 42 species. Hunters, trappers, and field biologists should be aware that serosurveillance during the 1990s revealed the presence of sylvatic plague and tularemia …


Effects Of Habitat On Clutch Size Of Ornate Tree Lizards, Urosaurus Ornatus, Gregory Haenel Aug 2011

Effects Of Habitat On Clutch Size Of Ornate Tree Lizards, Urosaurus Ornatus, Gregory Haenel

Western North American Naturalist

Clutch size is an important determinant of female reproductive success in reptiles. Although female body size explains much variation in clutch size, other important factors include differences in food availability, predation risk, morphology, and demography. Ornate tree lizards, Urosaurus ornatus, display extensive variation in life history traits, including clutch size. Tree lizards primarily use 2 distinct habitat types—trees and rock surfaces—which influence both the performance and morphology of this species and may affect life history traits such as clutch size. As food availability, microclimate, and, potentially, predator escape probabilities differ between these 2 habitats, I predicted that tree- and rockdwelling …


First Record Of Multiple Paternity In The Pygmy Rabbit (Brachylagus Idahoensis): Evidence From Analysis Of 16 Microsatellite Loci, Wilfredo Falcón, Caren S. Goldberg, Lisette P. Waits, Wendy A. Estes-Zumpf, Janet L. Rachlow Aug 2011

First Record Of Multiple Paternity In The Pygmy Rabbit (Brachylagus Idahoensis): Evidence From Analysis Of 16 Microsatellite Loci, Wilfredo Falcón, Caren S. Goldberg, Lisette P. Waits, Wendy A. Estes-Zumpf, Janet L. Rachlow

Western North American Naturalist

Although promiscuity is believed to be common among leporids, little is known about the mating system of free-ranging pygmy rabbits (Brachylagus idahoensis). We used 16 polymorphic microsatellite markers and DNA extracted from tissue samples of 10 rabbits from 2 litters collected in east central Idaho to evaluate paternity. We incorporated maternal genotypes for better resolution and employed an exclusion approach to detect multiple paternity. Our results demonstrated multiple paternity at 6 of the 16 loci tested for each litter. These findings support the expectation that pygmy rabbits have a promiscuous mating system. It has been proposed that multiple …


The Efficacy Of Social Communication Intervention In Improving Emotion Inferencing For School-Aged Children With Language Impairment, Matthew Keith Frank Aug 2011

The Efficacy Of Social Communication Intervention In Improving Emotion Inferencing For School-Aged Children With Language Impairment, Matthew Keith Frank

Theses and Dissertations

Children with language impairment (LI) have demonstrated several language problems, including receptive and expressive deficits. A growing body of research has further demonstrated emotion understanding and, more specifically, emotion inferencing deficits that negatively affect the ability of this population to use language successfully in social interactions. Consequently, the present study examines social communication intervention focused on improving emotion inferencing for children with a diagnosis of LI or Autism Spectrum Disorder (ASD), as similar social communication deficits are occasionally seen in children with these diagnoses. Study participants were identified from the caseload of a practicing certified speech-language pathologist (SLP) and qualified …

The Formation And Stability Of Radical-Molecule And Radical-Radical Complexes And Their Importance In Atmospheric Processes, Jared M. Clark Aug 2011

The Formation And Stability Of Radical-Molecule And Radical-Radical Complexes And Their Importance In Atmospheric Processes, Jared M. Clark

Theses and Dissertations

This research explores the role that radical-molecule complexes play in the chemistry of Earth's atmosphere. The formation of such complexes can have direct and pronounced effects on the reaction and product outcome of atmospheric chemical reactions. Some attention is also given to the formation of radial-radical pre-reactive complexes in the HO + ClO system. Peroxy radicals (RO2) can form stable complexes with polar compounds such as H2O, NH3, and CH3OH. For the simplest RO2 radical, HO2, complex formation (e.g., HO2-H2O, HO2-NH3, and HO2-722;CH3OH) gives rise to a significant increase in the HO2 self-reaction rate constant. Although this phenomenon has been …

Basic Training and Resources for Teaching English to Speakers of Other Languages (BTRTESOL) created by Dr. Lynn Henrichsen, is a basic but comprehensive program to provide skills and resources to teachers with limited formal training, …


Mechanisms Of Prenatal High-Salt "Fetal Programming" Resulting In Stress Hyperresponsiveness In The Adult Female Offspring In The Sprague Dawley Rat., Clinton L. Johnson Aug 2011

Mechanisms Of Prenatal High-Salt "Fetal Programming" Resulting In Stress Hyperresponsiveness In The Adult Female Offspring In The Sprague Dawley Rat., Clinton L. Johnson

Theses and Dissertations

Female offspring of Sprague-Dawley rats fed a high-salt diet (HS) during pregnancy show an enhancement of mean arterial pressure (MAP) and heart rate (HR) response to acute stress in adulthood compared to offspring whose mothers were fed a normal-salt diet (NS) [1]. In the present study, we first examined the expression of soluble epoxide hydrolase (SEH) protein in brain tissue. Whole brains were collected and SEH gene (EPHX2) mRNA and SEH protein expression were analyzed using RT-PCR and Western blot, respectively. mRNA levels were relatively decreased in high-salt rats (1.0 ± 0.32 NS vs 0.39 ± 0.07 HS, n=6). However, …


Scarification And Cultural Practice Of Four Lupine Species Native To The Great Basin, Covy Dennis Jones Aug 2011

Scarification And Cultural Practice Of Four Lupine Species Native To The Great Basin, Covy Dennis Jones

Theses and Dissertations

The Great Basin is North America's largest desert, encompassing 135 million acres. Grazing and other anthropogenic activities in the Great Basin have put heavy demands on the landscape over the last 150 years. Heavily grazed areas lack diversity which allows the spread of exotic weed species. Cheatgrass (Bromus tectorum L [Poaceae]) has invaded and shortened fire frequency intervals from historic 30—100 years to as few as three to five years. Post-fire reseeding of native species is requisite for restoration of highly invaded ecosystems thus, preventing complete conversion to exotic weeds. Most native shrubs and grasses are available for restoration …

The Characterization Of Avian Polyomavirus, Satellite Tobacco Mosaic Virus, And Bacteriophage Cw02 By Means Of Cryogenic Electron Microscopy, Peter S. Shen

Theses and Dissertations

Viruses are the most abundant biological entity in the biosphere and are known to infect hosts from all domains of life. The aim of my work is to identify conserved and non-conserved features among the capsid structures of related and divergent icosahedral viruses via cryogenic electron microscopy, sequence analysis, molecular modeling, and other techniques. Bird polyomaviruses often cause severe disease in their hosts whereas mammalian polyomaviruses generally do not. Avian polyomavirus is a type of bird polyomavirus with an unusually broad host range compared to the restricted tropism of other polyomaviruses. Although most polyomaviruses have a conserved, rigid capsid protein …

Félix Éboué: The Second Resister, Andrew Skabelund Aug 2011

Félix Éboué: The Second Resister, Andrew Skabelund

Student Works

On July 14, 1944, The New York Times reported that French citizens in New York were celebrating both the liberation of Normandy and Bastille Day. The French consul general in New York, Guerin de Beaumont, expressed gratitude for what he called the first time since the beginning of World War II that the French were able to celebrate the holiday in recently freed Normandy without interference. He expressed the hope that "perhaps in another year all of France will be able to celebrate the day so..."


Fast Relabeling Of Deformable Delaunay Tetrahedral Meshes Using A Compact Uniform Grid, David C. Frogley Jul 2011

Fast Relabeling Of Deformable Delaunay Tetrahedral Meshes Using A Compact Uniform Grid, David C. Frogley

Theses and Dissertations

We address the problem of fast relabeling of deformable Delaunay tetrahedral meshes using a compact uniform grid, with CPU parallelization through OpenMP. This problem is important in visualizing the simulation of deformable objects and arises in scientific visualization, games, computer vision, and motion picture production. Many existing software tools and APIs have the ability to manipulate 3D virtual objects. Prior mesh-based representations either allow topology changes or are fast. We aim for both. Specifically, we improve the efficiency of the relabeling step in the Delaunay deformable mesh invented by Pons and Boissonnat and improved by Tychonievich and Jones. The relabeling …


A Hell House Divided: Performing Identity Politics Through Christian Mediums Of Proselytization, Allan N. Davis Jul 2011

A Hell House Divided: Performing Identity Politics Through Christian Mediums Of Proselytization, Allan N. Davis

Theses and Dissertations

Every year, during the month of October, hundreds of Christian churches throughout the United States open the doors of their Hell House to surrounding communities. Hell Houses are Christian haunted houses designed to literally scare the Hell out of visitors so they will accept Jesus Christ as their personal Lord and Savior. In the place of vampires or zombies, Hell Houses portray the sins Satan is mostly likely to tempt teenagers to commit. Scenes include young girls receiving abortions, young men believing lies that they were born gay, and careless individuals drinking and driving. As para-theatrical performances, Hell Houses lead …


Oat Snp Marker Discovery And Mapping Based On 454 Pyrosequencing Of Genome-Reduced Avena Magna Murphy Et Terrell, Rachel Rebecca Redman Jul 2011

Oat Snp Marker Discovery And Mapping Based On 454 Pyrosequencing Of Genome-Reduced Avena Magna Murphy Et Terrell, Rachel Rebecca Redman

Theses and Dissertations

The size and complexity of the oat genomes (Avena L., x = 7) have made genetic studies, including the discovery of molecular markers, difficult. Recent attention to these species has resulted in the development of many DArT -based markers in the tetraploid A. magna Murphy et Terrill (2n = 28, CCDD genomes), along with numerous RFLP's, SSR's, DArT's, and EST-based SNPs in hexaploid A. sativa L. (2n = 42, AACCDD). Here we report the first SNP markers for tetraploid oat based on genome reduction and high-throughput pyrosequencing in two inbred lines of A. magna: A-169 (wild) and Ba …


Literary Love(R)S: Recognizing The Female Outline And Its Implications In Roman Verse Satire, Kaitlyn Marie Klein Jul 2011

Literary Love(R)S: Recognizing The Female Outline And Its Implications In Roman Verse Satire, Kaitlyn Marie Klein

Theses and Dissertations

The existence of a metaphoric female standing in for poetic style was only plainly discussed in a paper from 1987 concerned with Roman elegiac poetry. This figure is given the title of scripta puella or written woman, since her existence depends solely on the writings of an author. These females often appear to have basis in reality; however there is insufficient evidence to allow them to cross out of the realm of fantasy. The term scripta puella in poetry refers to a perfected poetic form, one the author prefers over all others, and a human form creates the illusion of …

Two-Dimensional Hydrodynamics Of Swimming Rainbow Trout Using Navier-Stokes And Large Eddy Simulation Models, Donovan R. Chipman Jul 2011

Two-Dimensional Hydrodynamics Of Swimming Rainbow Trout Using Navier-Stokes And Large Eddy Simulation Models, Donovan R. Chipman

Theses and Dissertations

Energy efficiency and propulsive characteristics of a 10 cm undulatory rainbow trout (oncorhynchus mykiss) swimming in a stationary position are considered. Two CFD simulations are performed utilizing dynamic grid meshing (FLUENT 6.3). The first simulation uses a laminar flow model with an added hydrofoil shape in order to test if thrust and drag can be brought to unity. The second simulation uses a Large-Eddy Simulation (LES) turbulence model to determine if transition to turbulence along the fish's surface leads to boundary layer separation. The expected results caused by adding these two features to earlier simulations do not occur. …

The Effects Of A Literature-Based Emotion Recognition Program On Teacher Report Of Sociability Withdrawal For Six Children With Social Communication Difficulties, Jennifer Lynn Harris

Theses and Dissertations

Children with language impairment (LI) often demonstrate difficulties in social communication. Although a number of general social communication interventions have been suggested, there is relatively little work done to examine the efficacy of these interventions for school-age children with LI, and none reported to target general emotional competence. The purpose of this study was to examine the effects on teacher perception of an intervention designed to improve emotion understanding. The intervention was centered on the presentation and use of children's stories to introduce and practice aspects of emotion understanding. The withdrawn and sociable subscales of the Teacher Behavior Rating Scale …


Calcineurin Is Required For Trpv1-Induced Ltd Of Ca1 Stratum Radiatum Interneurons, Tyron Deray Jensen Jul 2011

Calcineurin Is Required For Trpv1-Induced Ltd Of Ca1 Stratum Radiatum Interneurons, Tyron Deray Jensen

Theses and Dissertations

Learning and memory in the brain are thought to be dependent on synaptic plasticity. In response to sensory input, synapses can be strengthened or weakened, known as long-term potentiation or long-term depression (LTD), respectively. Transient receptor potential vanilloid 1 (TRPV1) has been shown to mediate a novel form of presynaptic LTD in hippocampal interneurons. TRPV1 is currently being heavily studied in the PNS and being targeted by pharmaceuticals for its anti-nociceptive and anti-inflammatory properties. However, much less is known regarding TRPV1 function in the CNS, including the signal mechanism mediating hippocampal LTD despite its obvious importance. Here we performed whole-cell …
