Probing Isoforms Of The Prion Protein Through Tyrosine Nitration, Christopher William Lennon

Graduate Student Theses, Dissertations, & Professional Papers

The prion protein (PrP) has multiple stable isoforms. When PrP misfolds, it aggregates and causes neurological disease and death in mammals. The structure of the non-pathogenic isoform has been determined while the structures of the disease related isoforms are unknown. The nitration labeling patterns of three PrP isoforms with peroxynitrite and tetranitromethane, as detected by mass spectrometry, are reported. Two conserved tyrosine residues (tyrosines 149 and 150) are not labeled by either reagent in the normal cellular form of the prion protein but these residues become reactive after the protein has been converted to one of two aggregated isoforms. Another …

Public Relations In Nonprofit Organizations: A Guide To Establishing Public Relations Programs In Nonprofit Settings, Megan Kate Gale

Graduate Student Theses, Dissertations, & Professional Papers

Public relations has become an increasingly popular topic in the nonprofit community, and the demand for developing piblic relations as a core competency has increased as well. Since many nonprofit organization have limited time and resources for developing fuull-scale public relations programs, many rely on information obtained during one-day workshops or conference presentations presented by public relations professionals who have little or no experience with the concerns of the nonprofit setting. Using a program planning model, this paper describes how nonprofit organizations can increase the capacity and effectiveness of their public relations efforts by building relationships with key stakeholders.

Public Archaeology In Montana: A Sample Of University Of Montana Students' Perceptions Of Archaeology And Knowledge Of Local Sites, Helen Alexandra Keremedjiev

It included topics on the basics of archaeology and sites in Montana. After the results were tabulated, a website was created to show the overall results. Its location is at www.umt.edu/publicarchaeology. This online resource includes the questionnaire, the total raw results of all classes’ responses, and a discussion section. (See Appendix E for screenshot images of the website.) This …

Changing Attitudes: Congressional Rhetoric, Race, And Education Inequalities, Jennifer Kathleen Richert

Graduate Student Theses, Dissertations, & Professional Papers

Richert, Jennifer Kathleen, M.A., May 2007 IYFD Changing Attitudes: Congressional Rhetoric, Race, and Education Inequalities Chairperson: Otto Koester Through an analysis of Congressional rhetoric regarding public school in the context of racial equality, three terms emerge as reoccurring concepts that drive discussions on contemporary educational conversations: narrowing the gap, disadvantaged students, and accountability. I have designed this study to determine whether the way politicians in U.S. Congress use these terms have racial undertones that ultimately work to maintain a culture of minority oppression. This study opens with an introduction describing my personal interest, followed with an extensive literature review regarding …

Development Of Fecal Dna Sampling Methods To Assess Genetic Population Structure Of Greater Yellowstone Bison, Florence Marie Gardipee

Graduate Student Theses, Dissertations, & Professional Papers

The bison (Bison bison) of Yellowstone National Park (YNP) and Grand Teton National Park (GTNP) represent two of only three remaining populations of plains bison that have no evidence of hybridization with cattle. Therefore, these bison are an important source for ecological and genetic restoration of wild bison. Little is known regarding genetic population structure and gene flow among the Greater Yellowstone Area (GYA) bison herds. I evaluated the feasibility of fecal DNA sampling for genetic analyses of wild bison populations. I used matched blood and fecal samples from eight radio-collared bison from Hayden Valley breeding group (YNP), and multiplex …

Examining The Variability In The Long Term Adjustment Of Child Sexual Abuse Victims, Heather Marie Ulrich

Graduate Student Theses, Dissertations, & Professional Papers

Two meta-analyses (Rind, Tromovitch & Bauserman, 1998; Ulrich, Randolph, & Acheson, 2006) have suggested that the long held belief about the inevitable pervasive negative effects of child sexual abuse does not hold for college populations. The meta-analyses suggest that there is other factors in sexual abuse victims' lives that interact with their abuse experience to produce the sometimes-observed minimal long-term effects on psychological adjustment. This research attempted to examine a potential model for explaining the variability in the long-term effects of child sexual abuse by examining both moderator variables and abuse characteristics within the same population. The study examined three …

Expression And Regulation Of Emotions In Romantic Relationships, Makon Fardis

Graduate Student Theses, Dissertations, & Professional Papers

Romantic relationships are extremely important in people's physical and mental well being. One of the important determinants of the quality of romantic relationships is the expression and regulation of emotions. This study hypothesized that 1) expression of positive emotions is good for any relationship, 2) expression of negative emotions is good for only communal relationships, 3) expression of positive emotions is necessary alongside of negative ones to maintain a communal relationship, 4) in case negative emotions are expressed, providing explanations would help maintain the relationship, 5) suppression of emotions does not benefit communal relationship, and 6) expression of emotions correlates …

Influence Of Mycorrhizal Inoculation Treatments On Native Tree And Shrub Survival In A Floodplain, Flathead Indian Reservation, T. Rene Kittle

Graduate Student Theses, Dissertations, & Professional Papers

Mycorrhizal inoculum treatments of two marketed products, Mycopak and Biogrow, were tested against forest soil, and a control treatment on biomass and survival of Populus tremuloides, Salix bebbiana, Populus trichocarpa, and Cornus stolonifera during the summer of 2003 and 2004. Because these seedlings are difficult to establish on cobbled riparian floodplains, the species and treatments were tested on two Jocko River floodplains. The Powell site was plowed in the spring of 2003 prior to planting, and the Stranahan site remained unplowed but treated with the broad leaf herbicide 2,4-D amine, in the fall of 2002. Seedlings were planted in the …

Moving Boxes Closer To Home: The Role Of Sysco Corporation In Food System Localization, David Scott Kennedy

Graduate Student Theses, Dissertations, & Professional Papers

Increasing demand for local food by foodservice establishments creates new opportunities and challenges for the local food movement. While there is considerable potential for local suppliers to sell more product volume closer to home, the business needs of foodservice establishments may not be compatible with direct marketing approaches that have fueled the growth of the movement. Foodservice establishments typically rely on distributors to provide them with the majority of their food. Drawing on the success of direct marketing, new indirect marketing approaches that link producers and consumers through intermediaries are increasingly advanced within food system localization. The dominance of SYSCO …

Negotiated Forgiveness In Parent-Child Relationships: Investigating Links To Politeness, Wellness And Sickness, Jennifer Lynn Geist

Graduate Student Theses, Dissertations, & Professional Papers

Upon experiencing conflict in a relationship, individuals have a variety of response options. While one can seek revenge or avoid that person, another option – forgiveness – can repair the relationship and foster health for both relationship partners. In coming together to confront the conflict and move beyond it, relational partners negotiate forgiveness in interpersonal interactions to accommodate face needs. In doing so, individuals must communicate by seeking forgiveness from and granting it to their relational partners. While much research has pointed to the health benefits associated with forgiving, little has explored the role communicating specifically plays in later received …

Elucidation Of The Specificity Of Neuroactive Steroids And Related Compounds At The At The Vesicular Glutamate Transporter, Wesley Edward Smith

Graduate Student Theses, Dissertations, & Professional Papers

As the primary excitatory amino acid, glutamate is essential to proper functioning of the mammalian CNS. Proper regulation of the synaptic release of glutamate, potentially regulated by synaptic vesicle content, is one of many critical aspects to normal excitatory functioning. In particular, the vesicular glutamate transporters (VGLUTs), which load synaptic vesicles with glutamate prior to presynaptic release of neurotransmitter, are distinct from that of the plasma membrane excitatory amino acid transporters (EAAT). The development of a library of compounds which selectively inhibit the uptake of [3H]-L-glutamate into the VGLUTs, has revealed importance of particular structural motifs. Among these structural motifs, …

Energy Flow In A Floodplain Aquifer Ecosystem, Brian Reid

Graduate Student Theses, Dissertations, & Professional Papers

We developed an energy budget to identify energy sources for the invertebrate community of a large 20 km2 floodplain aquifer, based on biomass distributions, organismal respirometry, in situ community respiration, mesocosm and microcosm experiments, stable isotopes and invertebrate gut contents. The invertebrate respiration scaling exponent was 0.474 (+/- 0.068, 95% CI) across six orders in body mass, which is significantly lower than the ¾ power scaling predicted by metabolic theory. Invertebrate production was dominated by copepods (Diacyclops, Acanthocyclops, Bryocamptus), Stygobromus amphipods, and amphibiont stoneflies, and ranged from 26.9 to 4200 mg C/m3 sediment/year. Production and density showed a U-shaped response …

The Role Of Attention In Second Language Development, Amanda Marie Mcginnis

Graduate Student Theses, Dissertations, & Professional Papers

This pilot study investigated the role of attention in language learning. I began by examining the most current research into how attention functions in the brain; then I discussed how attention as a cognitive mechanism is believed to fit into models of data processing and language learning. Once the nature and role of attention in language development was understood, it became possible to discover the practical implications for language teachers and learners. The most recent means to a grammar pedagogy is the Focus on Form approach: a language teaching option which takes into account the research on the role of …

Distance From Family, Years Of Life On Reservation/Village, Level Of Acculturation, Gender, And Acculturation Stress Of American Indian/Alaska Native Students At The University Of Montana, Michael Brian Trahan

Graduate Student Theses, Dissertations, & Professional Papers

Acculturation is a construct that supposes that two or more cultures interact and are in conflict with one another, and an individual can determine which qualities to adhere to from each culture. Acculturation stress is a product of the acculturation process, in which an individual experiences stress as a result of the interaction of the multiple cultures upon the individual. This study examined the effects of acculturation stress on 41 (14 male and 27 female) American Indian/Alaska Native (AI/AN) university students in an effort to determine whether this stress is related to level of acculturation, years lived on an Indian …
