Diagramming Tpack In Practice: Using An Elaborated Model Of The Tpack Framework To Analyze And Depict Teacher Knowledge, Suzy Cox, Charles R. Graham

Faculty Publications

The introduction of the TPACK model by Mishra and Koehler (2006) has had a profound impact on the field of educational technology. It has inspired teachers, teacher educators, and educational technologists to reevaluate their knowledge and use of technology in the classroom. While Koehler, Mishra, and others have attempted to define and measure TPACK, the framework is not yet fully understood (Angeli & Valanides, 2009). Thus far, the explanations of technological pedagogical content knowledge and its associated constructs that have been provided are not clear enough for researchers to agree on what is and is not an example of each …

Tobacco Use Among Alaska Native And American Indian College Students, Sarah Angstman

Graduate Student Theses, Dissertations, & Professional Papers

The prevalence of tobacco use is disproportionately high among American Indian and Alaska Native people, with rates and patterns of use varying greatly by tribe, community and geographical region. Targeted interventions are needed to reduce this troubling disparity between non-Native and Native rates of use. Among non-Native individuals, the college years are being investigated as a time when lifelong tobacco use patterns may be established, and interventions are being tested to help college students to stop using tobacco. Currently, no interventions have been developed for American Indian or Alaska Native college students. Data obtained from Alaska Native college students at …

The Potential Of Asynchronous Video In Online Education, Michael E. Griffiths, Charles R. Graham

Faculty Publications

There are differences in the benefits that are afforded by the two extremes of face-to-face and distance education. University campus courses are based on the assumption that the student community and interaction between learners and an expert teacher in the same physical location is essential to the learning process. In comparison, distance education provides a learner with flexibility, individualized learning, lower costs, and self-determination in the learning process. Much research has been invested into modern approaches that may be able to harness key benefits from both face-to-face and distance education. One recent breakthrough has come in the use of asynchronous …

Water Quality And Waterborne Disease Along The Niger River, Mali: A Study Of Local Knowledge And Response, Ashley Lauren Williams

Graduate Student Theses, Dissertations, & Professional Papers

This paper presents the findings of a study to assess patterns in local knowledge of and response to water quality and waterborne diseases in relation to seasonal changes in the Niger River Inland Delta. The study draws on field data collected in four villages along the Niger River in the Mopti district of Mali during September 2008. The major findings suggest: (1) water use behaviors and diarrheal disease management are influenced by the tremendous seasonal fluctuations in the riverine environment; (2) local awareness of the relationship between poor water quality, oral-fecal disease transmission, and waterborne disease is low; (3) interventions …

Upstream Geomorphic Response To Dam Removal: The Blackfoot River, Montana, Joshua Aaron Epstein

Graduate Student Theses, Dissertations, & Professional Papers

As dam removal is increasingly used as a tool to restore rivers, developing a conceptual and field-based understanding of the upstream fluvial response is critical. Using empirical data and modeling, I investigated the spatial and temporal pattern of reservoir sediment erosion and upstream channel evolution of the Blackfoot River, MT, following the 8 m base level reduction caused by the removal of Milltown Dam. Field data collected include surveys of channel bed topography and water surface elevation profiles which were integrated into a flow modeling approach. Headward erosion extended 4.5 km upstream of the dam site during the first five …

Factors Contributing To Improved Teaching Performance, Whitney Ransom Mcgowan, Charles R. Graham

Faculty Publications

This article focuses upon the quality and scholarship of teaching as it pertains to educational and faculty development. We outline what more than 200 faculty members at one institution have done over a 3-year period to make significant and sustained improvements in their teaching, surprisingly with minimal effort. The top three factors leading to improvement were active/practical learning, teacher/student interactions, and clear expectations/learning outcomes. We provide practical applications for change and suggestions for future research.

Worlds Apart: Social Mechanisms Of Contrasting Fertility In European American And Native American Populations On The Northern Plains, Janet Mary Bush

Graduate Student Theses, Dissertations, & Professional Papers

The purpose of this study was to explore the relationship between fertility and household economy on Montana's Northern Plains. Low fertility and outmigration in European American communities have led to dramatic depopulation of the region. At the same time, isolated Indian reservations in the area have grown in population due to high fertility and return migration.

A mixed methods research approach was used to explore the relationship between fertility and social acceptance of communal household economic strategies. Census data and birth records described differences in fertility and household economy between European American and Native American populations in six Plains Indian …

Youth Harvest: Exploring An Employment-Based, Service-Oriented, Therapeutic Program For “At-Risk Youth”, Rachel Christine O'Brien

Graduate Student Theses, Dissertations, & Professional Papers

In the mid-1990s, juvenile courts began establishing youth drug courts that blended the principles of restorative justice and the philosophy of therapeutic jurisprudence in an attempt to process juvenile drug offenders in a way that emphasizes rehabilitation of the offenders and restoration to the community. Over recent decades, wilderness therapy programs and horticultural therapy programs have become popular as alternative approaches for treating adjudicated and/or “at-risk” youth. The Youth Harvest program, which operates in conjunction with the Missoula Youth Drug Court, is a unique, therapeutic program that blends the goals of National Drug Courts and the principles of restorative justice …

Internal Audit Quality And Earnings Management, Douglas F. Prawitt, Jason L. Smith, David A. Wood

Faculty Publications

Internal auditors often perform work that is relevant to their host entities’ financial reporting processes, yet little research attention has focused on the effects of internal auditing on companies’ external financial reporting. Using a unique and previously unavailable data set, we investigate the relation between internal audit function (IAF) quality and earnings management. We measure IAF quality using a composite measure comprising six individual components of IAF quality based on SAS No. 65, which guides external auditors in assessing the quality of an IAF with respect to its role in financial reporting. Earnings management is measured using two separate proxies, …

An Empirical And Consumer Psychology Analysis Of Trademark Distinctiveness, Thomas R. Lee, Eric D. Derosia, Glenn L. Christensen

Faculty Publications

This article analyzes the taxonomy of trademark distinctiveness that has long been endorsed in the courts and scholarly commentary. This distinctiveness scale is routinely justified on the basis of an assumption about consumer psychology: that consumers perceive suggestive, arbitrary, or fanciful marks as source-indicating, but see descriptive marks as "merely descriptive." Although this core premise of trademark law is a fundamental matter of consumer psychology, it has never been subjected to scrutiny under the light of consumer psychology theory and empirical analysis. We offer a consumer psychology model for questioning the law of distinctiveness (or "source indication") and then test …

Disclosure Quality And The Mispricing Of Accruals And Cash Flow, Michael S. Drake, James N. Myers, Linda A. Myers

Faculty Publications

In this paper, we investigate the role that disclosure quality plays in the accurate valuation of accruals and cash flow. We predict that stock prices of firms with higher-quality disclosures more accurately reflect the persistence of accruals and cash flow. We test our predictions using analyst ratings of disclosure published in the annual Association for Investment Management and Research (AIMR) Corporate Information Committee Reports for the years 1982 through 1996. The results provide strong evidence of mispricing for the subset of firms with lower-quality disclosures and of a significant reduction in mispricing for the subset of firms with higher-quality disclosures. …

Earnings Misstatements, Restatements, And Corporate Governance, William G. Heninger, Yongtae Kim, Sandeep Nabar

Faculty Publications

High profile financial restatements from companies like Enron, Worldcom, Healthsouth, and Tyco as well as less celebrated restatements from such companies as Red Hat, Nortel, and Bristol-Myers Squibb have shaken public trust in the U.S. capital market. The restating companies have watched their credit ratings drop, market values erode, and occasionally even faced bankruptcy (Palmrose et al. 2004; Hirschey et al. 2005). The preponderance of restatements, in part, led to the enactment of the Sarbanes-Oxley Act which reemphasized the need for, and the importance of, strong corporate governance.

Explorations In Leadership Education: The Role Of Leadership Education In Higher Education Outcomes, Douglas G. Mcbroom

Graduate Student Theses, Dissertations, & Professional Papers

There has been much criticism of academic leadership programs for not adequately preparing leaders. This is the case for all of the major programs: business administration, educational leadership, military science, and public administration. However, these evaluations themselves are limited inasmuch as they are typically concerned with such dimension as students' satisfaction and faculty credentials and performance while organizational outcomes attributable to leadership are ignored. The present research investigates the relationship of institutional outcomes for colleges and universities and the presence or absences of presidents with formal leadership training. The outcomes indicators are those contained in the Integrated Postsecondary Educational Data …

A Comparison Study Of Montana's Intermediate And K-8 Schools With Regard To Student Performance On A Criterion Referenced Test, Incidence Of At-Risk Behaviors, And Perceptions Of Educators From Both Grade Configurations, Robert Jeffrey Watson

Graduate Student Theses, Dissertations, & Professional Papers

Within the last ten years, middle schools have been criticized for focusing too much on social development while ignoring academics. Several large school districts around the country are transforming their middle schools into K-8 schools. The purpose of this mixed methods study was to compare K-8 schools with intermediate schools in the State of Montana. Quantitative research examined the relationship between school grade configuration and student performance on a criterion referenced test. Descriptive analysis examined the relationship between school grade configuration and incidence of at-risk behavior among students. Additional data was collected through 1-1 comparison interviews with educators from both …

Biosignature Storage In Sulfate Minerals- Synthetic And Natural Investigations Of The Jarosite Group Minerals, Julia Michelle Kotler

Graduate Student Theses, Dissertations, & Professional Papers

The discovery of jarosite on Mars in 2004 generated increased interest in the properties of the mineral related to the search for life on other planets. Several studies indicate that the formation of jarosite can be linked to biological activity on Earth and biomolecules such as amino acids have been found associated with terrestrial jarosite samples. A series of natural and synthetic investigations using different jarosite end-members has been conducted and is presented in this dissertation to investigate the possibility that jarosite can store biosignatures. Natural samples were analyzed by x-ray diffraction, elemental carbon analysis and laser-desorption Fourier transform mass …

Art For Life: A Spiritual Journey Of Art And The Bonds Of Community, Tara Lynn Smith

Graduate Student Theses, Dissertations, & Professional Papers

Within mainstream culture exists an accepted protocol by which most people function in daily life. The majority of the population has a standard way of life without much detour to other possibilities. Sometimes this canonical does not seem quite right. The potential detour then becomes increasingly difficult to ignore because a disconnect of community runs rampant in the corners of our culture. My intuition regarding a way to live differently coupled with a spiritual connection and life-purpose, has caused me to take action in unexpected ways resulting in outcomes of revelation. In pursuit ways to re-connect to the significance of …

Reinvention In The Line Of Death: A Reconsideration Of Geoffrey Hill's Commemorative Verse, Michael Christopher Bartch

Graduate Student Theses, Dissertations, & Professional Papers

This paper considers the embodied ethics of Geoffrey Hill’s poetic practice. Hill stages his engagement with poetry through the idioms, images, tropes, and diction of the literary tradition. Through this pragmatic rehearsal of the language of the dead, Hill’s poetry projects the tradition into the present. Hill resists the ethical entrapments of appropriative poetry through his insistence upon the brute physicality of atrocity and through a rigorous (for both poet and reader) formal difficulty. Hill’s practice refuses to console after the models of Peter Sacks, Jahan Ramazani, or John Vickery. Instead, concerned with modernity’s disconnectedness, Hill’s poetry returns us to …

Changes In Fire Season Precipitation In Idaho And Montana From 1982-2006 , Ann Marie Hadlow

Graduate Student Theses, Dissertations, & Professional Papers

Abstract. Fire season precipitation trends were investigated using daily rainfall data obtained from seventy-six Remote Automated Weather Stations (RAWS) across Idaho and Montana for the period 1982 to 2006. Missing and erroneous values from each station were corrected with gridded data from the North American Regional Reanalysis (NARR), creating temporally consistent, comparable records. Monthly precipitation was then analyzed during the core fire season (July-Sept) and biweekly precipitation was analyzed for the start of fire season (June). The end of the season was examined using October precipitation data and through identification of season slowing rain events (SSE). These analyses reveal significant …

Animal Vegetable Mineral, Eva Lys Champagne

Graduate Student Theses, Dissertations, & Professional Papers

There is a radical unity supporting the vast diversity of appearances in nature that makes distinct categorizations like “animal, vegetable or mineral” superficial at best. The unifying element has been called energy, or, as Emerson put it, “thought is the common origin.” This guiding principle, a life spent by the sea, and an enduring fascination with nature’s forms, has resulted in my current body of work. By combining formal references to animals, vegetables and minerals I create intentionally ambiguous ceramic sculptures that seem to exist in the fluid margin between categories. My aim is toward something composite that challenges the …

Identification And Characterization Of Novel Astroviruses, Stacy Finkbeiner

All Theses and Dissertations (ETDs)

Approximately 1.8 million children die from diarrhea annually, and millions more suffer multiple episodes of nonfatal diarrhea. Despite the availability of improved molecular diagnostics to detect the known viral agents, the etiology of a large proportion of diarrheal cases is unknown. In fact, it is estimated that no causative agent can be identified in up to 40% of sporadic cases or in gastroenteritis outbreaks. Detection of novel or unexpected viruses is the first step in identifying agents that could potentially close the diagnostic gap and pave the way for the development of more comprehensive preventative measures and better treatments. This …

In Vivo Function Of Otopetrin 1 In The Vestibular Sensory Epithelium, Euysoo Kim

All Theses and Dissertations (ETDs)

Otopetrin family genes encode multi-transmembrane domain proteins with three highly conserved domains. In mice, three Otopetrin paralogues are found. One of its members, Otopetrin 1: Otop1) has been previously shown to be essential for the formation of otoconia in the vestibular system of the inner ear. Otoconia are calcium carbonate biominerals that are required for normal balance and the sensation of linear acceleration with respect to gravity. The mechanism by which OTOP1 mediates otoconia biosynthesis is not known, but the ability of OTOP1 to modulate [Ca2+]i in response to purinergic signals in heterologous systems suggest that OTOP1 may be involved …

Hiv-1 Envelope-Induced Signaling Mediates Actin Cytoskeleton Rearrangements Necessary For Fusion And Entry, Brooke Harmon

All Theses and Dissertations (ETDs)

Human immunodeficiency virus type-1: HIV-1) initiates infection by direct fusion of the virus membrane with the plasma membrane of the target cell. This fusion event is a multi-step process mediated by the envelope: Env) surface subunit gp120 and the transmembrane subunit gp41 which anchors gp120 into the viral membrane. First the surface subunit gp120 binds to the primary receptor CD4. This interaction promotes actin cytoskeletal rearrangements in the target membrane that bring the chemokine coreceptor, CCR5 or CXCR4, into close proximity for binding and induces conformational changes in gp120 that allow it to couple to the coreceptor. Formation of the …

Aggregation & Localization Of A Disease-Associated Prion Protein (Prp) Mutant, Andrea Rhonda Medrano

All Theses and Dissertations (ETDs)

ABSTRACT OF THE DISSERTATION Aggregation & Localization of a Disease-Associated Prion Protein: PrP) Mutant by Andrea Rhonda Zaragoza Medrano Doctor of Philosophy in Biology and Biomedical Sciences: Genetics) Washington University in St. Louis, 2009 Professor David A. Harris, Chairperson Prion protein: PrP) is a GPI-anchored sialoglycoprotein involved in the pathogenesis of infectious and inherited forms of transmissible spongiform encephalopathies: TSEs). A nine-octapeptide insertional mutation in the prion protein: PrP) causes a fatal neurodegenerative disorder in both humans and transgenic mice. To determine the precise cellular localization of this mutant PrP: designated PG14), we have generated transgenic mice expressing PG14-EGFP, a …

Regulation Of Bax/Bak-Dependent Cell Death Program, Hyungjin Kim

All Theses and Dissertations (ETDs)

Mammals have evolved an intricate regulation of a genetically programmed apoptotic cell death that involves mitochondria. Diverse apoptotic signals converge on mitochondria, which causes the release of cytochrome c into the cytosol to activate Apaf-1. This initiates caspase activation, which results in irreversible cellular demise. The BCL-2 family proteins constitute a critical checkpoint in mitochondrion-dependent apoptosis. Multidomain proapoptotic BAX/BAK promotes mitochondrial outer membrane permeabilization, whereas anti-apoptotic BCL-2/BCL-X_L/MCL-1 protects mitochondrial integrity and prevents cytochrome c release. The proapoptotic activity of BAX/BAK is triggered by BH3-only molecules: BH3s) which are upregulated by upstream death signals. However, how these subfamilies interact …

Role And Regulation Of Escrt-Iii In Multivesiculr Body Biogenesis, Soomin Shim

All Theses and Dissertations (ETDs)

Endosomal sorting complex required for transports: ESCRT) machinery responsible for multivesicular body: MVB) biogenesis is essential for receptor downregulation, viral budding and cytokinesis. ESCRT-III is a large polymer built from related ESCRT-III proteins that is thought to help generate intralumenal vesicles: ILVs) within the MVB. How ESCRT-III functions is poorly understood. Although ESCRT-III assembles on the endosomal membrane, its components are predominantly soluble in the cytoplasm. I found that the transition between these two states is controlled by autoinhibitory domains within ESCRT-III proteins, which I identified by structure/ function analysis in four human ESCRT-III proteins - Charged multivesicular body protein2A: …

The Role Of Astrocyte Activation In Infantile Neuronal Ceroid Lipofuscinosis, Shannon Macauley-Rambach

All Theses and Dissertations (ETDs)

Infantile neuronal ceroid lipofuscinoses: INCLs), or Batten Disease, is an inherited neurodegenerative lysosomal storage disorder affecting the central nervous system: CNS) during infancy or childhood. Hallmark pathological changes include accumulation of autofluorescent material, neuronal loss, cortical thinning, and brain atrophy, which ultimately lead to cognitive deficits, motor dysfunction, seizure activity, and blindness. INCL is the result of mutations in the CLN1 gene leading to a deficiency in the lysosomal enzyme, palmitoyl protein thioesterase 1: PPT1). A mouse model of INCL, the PPT1-deficient: PPT1-/-) mouse, was recently created by a targeted disruption in the CLN1 gene. The phenotype of the PPT1-/- …

Monitoring Noxious Weeds Invasions In Riparian Areas Following Livestock Exclusion Of The Upper Big Hole River Valley: Adaptive Management Under The Candidate Conservation Agreement With Assurances Project, Ana Ingrid Pederson

Graduate Student Theses, Dissertations, & Professional Papers

As a 2008 summer intern working for the Nature Conservancy, I arrived in the Big Hole Valley and was introduced to an innovative federal land management program initiated to benefit government land managers, local ranchers, and the general public while increasing ecological integrity in the valley and recovering the fluvial Arctic grayling species. The government program offered funding assistance to local ranchers for conservation projects that would help recover the species, but the landowner had to agree to a few stipulations; among them are riparian enclosures fenced for 5 years to exclude all domestic grazing. The goal of this project …
