Identifying perceptions of health promotion barriers and benefits in individuals at risk for coronary heart disease: Author: Weston, Nicolett Marie; Date: 2008-05-15; Program: Nursing; Abstract: Coronary Heart Disease (CHD) is the single largest cause of death in the U.S., and is also the leading cause of death in Montana. In addition, the estimated direct and indirect costs of cardiovascular disease in the U.S. for 2007 were $431.8 billion. Anticipated barriers to health promotion behavior have been shown to affect intentions to engage in and execute the behaviors. Exploring individual's perception of the benefits of health promotion behaviors is equally important when addressing barriers to making lifestyle changes. CHD is strongly associated with modifiable risk factors including ...; Download File | View full details

Sleeping with the Enemy: Integrating Big-Box Retail with Existing Communities: Author: Nash, Ronald James; Date: 2007-05-15; Program: Architecture; Abstract: The intent of my thesis is to find a way to integrate a large big-box retailer into a community in such a way that it benefits the community as a whole. This must be accomplished within the parameters that mark the store as a viable option for the parent company as well. This ideal must be approached from the philosophy that box stores are a large part of the current American way of life and to let them grow unchecked will signal the inevitable death of downtown retail districts as more and more business gets sucked to the super-stores and the areas immediately surrounding them. To do this we ...; Download File | View full details

Redlining in Montana: Author: Schumacher, Joel Brent; Date: 2006-05-15; Program: Applied Economics; Abstract: Redlining is the practice of using the attributes of geographic location of a mortgage loan as the basis for differential and typically adverse treatment of an application. This is a particularly important social problem in the home mortgage market due to benefits which have been shown to be correlated with home ownership. Minority and low income applicants may find redlining to be a major barrier to obtaining home ownership and the benefits associated with being a home owner. This thesis uses a data set collected under the Home Mortgage Disclosure Act to examine the mortgage market in Montana...; Download File | View full details

The Effects of Prescribed Fire on Riparian Groundwater: Author: Tucker, Ronald A. Jr.; Date: 2007-05-15; Program: Animal and Range Sciences; Abstract: The hypothesis of this study is that the use of prescribed fire to reduce trees and tree canopy, on a watershed scale, will decrease depth to riparian groundwater, increase riparian plant species diversity, and increase riparian biomass production. To test these hypotheses two watersheds, primarily managed for cattle grazing, located in Fergus (Dry Armells watershed) and Jefferson (Little Whitetail watershed) Counties, Montana, were chosen. Both watersheds were densely dominated with coniferous tree species. Average preburn tree density was 1,276 trees/ha and 350 trees/ha for both the Dry Arme...; Download File | View full details

Entrainment Losses of Westslope Cutthroat Trout into Screened and Unscreened Irrigation Canals on Skalkaho Creek, Montana: Author: Gale, Steven Burton; Date: 2005-08-15; Program: Fish and Wildlife Management; Abstract: Irrigation canals are known to entrain anadromous and potamodromous salmonids of all life stages during their annual migrations. Fish screens may reduce or eliminate entrainment, but few studies exist on their benefits and these have evaluated effects on anadromous populations only. Prior to my study, none existed on the benefits of fish screens for non-anadromous salmonids. Large numbers of post-spawn adult and downstream migrant juvenile westslope cutthroat trout (Oncorhynchus clarkii lewisi) are potentially entrained into the seven irrigation canals on Skalkaho Creek, a tributary of the Bit...; Download File | View full details

Process voltage temperature compensated on-chip CMOS active inductors for Wilkinson power dividing applications: Author: Bucossi, William Louis; Date: 2008-05-15; Program: Electrical Engineering; Abstract: Few academic or industry feasibility studies have been published on the implementation of Active Inductors in a standard CMOS IC process as an alternative to the physically large and typically quite lossy spiral inductors. Development efforts at the simulation level have achieved only limited success in creating an Active Inductor topology that exhibits the quality and inductive tolerance necessary for the large-scale, high-volume production common to most IC components. This thesis focuses on manufacturing and characterizing the basic component circuitry necessary for the implementation of a ...; Download File | View full details

Perceived Social Support in Young Adults with Cancer and the Camp Experience: Author: Handley, Stacy Marie; Date: 2004-08-15; Program: Nursing; Abstract: During the years when a peer social support network should be formed, children and adolescents with cancer are in hospitals and are surrounded by protective parents and family. Literature suggests there are many benefits associated with formation of a social support network including improvement of health status but few childhood cancer survivors have had the opportunity to form these networks. The purpose of this study is to determine if there is an increase in reports of social support after attending an oncology camp. A non-random convenience sample of 18 to 25 year olds with a diagnosis of...; Download File | View full details

Theorizing Nature: Seeking Middle Ground: Author: Voss, Dahlia Louise; Date: 2005-05-15; Program: English; Abstract: Acknowledging that our ideas about nature and culture are both inextricably linked and the result of social factors shaped by multiple forms of knowledge is at the center of this project. Through a postmodern analysis, informed by environmental cultural studies, I critique a relatively new genre, the environmental memoir, to theorize the ways interconnections between nature and culture are either resisted or revealed. Environmental memoir is a genre-hopping exploration of both personal narrative and environmental literature. Critiquing the literary constructions of nature, culture, environment...; Download File | View full details

Symbiotic Nitrogen Fixation and Establishment of Six Montana Native Legumes Species: Author: Metcalf, Sarah Jean; Date: 2005-08-15; Program: Land Rehabilitation; Abstract: Legume species have been known to increase soil N content and are incorporated into land restoration seed mixes in hopes of improving degraded soils and plant communities. The goals of this project were to determine effects of soil type, soil moisture, inocula and fungicide treatments on legume establishment, N₂ fixation capacity and plant biomass for six individual native legume species. In potted greenhouse studies, legumes were grown in five field soils to verify nodulation without inocula. In a second phase, plant biomass was measured in two soils at two moisture contents (60 and 8...; Download File | View full details

Behavioral Responses of Elk (Cervus elaphus) to the Threat of Wolf (Canus lupus) Predation: Author: Winnie, John Arthur, Jr.; Date: 2006-05-15; Program: Biological Sciences; Abstract: We studied individual and herd level behavioral responses of elk to spatial and temporal variation in the risk of predation by wolves over three winters in the Upper Gallatin drainage, Montana. Within a given drainage, elk of both sexes moved into or closer to protective cover (timber) in response to wolf presence. Cow elk responded to elevated risk by increasing vigilance in exchange for foraging, and large mixed (cow, calf, spike) herds substantially decreased in size. In contrast, when wolves were present, bulls did not increase vigilance levels, nor decrease feeding, and small bull-only gr...; Download File | View full details

Barriers to Participation in Cardiac Rehabilitation: A Rural Perspective: Author: Echeverri, Rebecca Chloe; Date: 2007-05-15; Program: Nursing; Abstract: Cardiovascular disease is a significant health problem in rural states and complicated by the lack of access to specialized health care services such as cardiac rehabilitation programs. Researchers have documented that education, counseling, and behavioral interventions are important elements of cardiac rehabilitation (CR) that lead to decreased mortality and increased quality of life. Despite the known benefits of participation, only 10-20% of eligible persons in the United States participate in CR. While evidence exists to partially explain participation in cardiac rehabilitation programs, a...; Download File | View full details

Application of the Modeling Role-Modeling Theory to Mentoring in Nursing: Author: Lamb, Patricia Darlene; Date: 2005-08-15; Program: Nursing; Abstract: Mentoring has existed in some form since the days of Greek mythology. Today the debate is whether mentoring is really valuable at all, if the absence of a single definition interferes with its usefulness, and whether those in nursing perceive it useful within their profession. Purpose: The purpose was to explore the applicability of the MRM Theory to the relationship of nursing educators as mentors and students as mentees. This descriptive exploratory study aims were to 1) determine if the theory concepts were considered realistic to nursing faculty and nursing students, in relation to the men...; Download File | View full details

Employing Visitor Studies and Video Media to Better Communicate Science in National Parks: Author: Koch, Alison Lindsey; Date: 2007-05-15; Program: Science and Natural History Filmmaking; Abstract: The future of the National Park Service depends upon the agency's ability to educate the public to care for and preserve America's parks.

Assessing Constructed Wetlands for Beneficial Use of Saline-Sodic Water: Author: Kirkpatrick, Amber Denise; Date: 2005-05-15; Program: Land Resources and Environmental Sciences; Abstract: Changes in agricultural practices, and irrigation strategies combined with natural processes, have led to increased salinization of soil and water resources worldwide. Coal bed methane (CBM) development in the Powder River Basin of Montana and Wyoming results in the co-production of large volumes of sodic and moderately saline discharge water, and represents a potential source of salinization of soil and water resources. The objective of this study was to evaluate the potential of constructed wetlands as a tool for CBM product water management. This was accomplished by assessing seasonal water...; Download File | View full details

Consumer Awareness and Interest in Omega-3 Fats and Applications for Marketing Culinary Camelina Oil: Author: Weems, Tyson Victor; Date: 2007-05-15; Program: Health and Human Development; Abstract: Camelina sativa is a oilseed-bearing plant that grows in Montana and from which can be extracted oil containing 30-42% alpha-linolenic acid, an essential "omega-3" fatty acid. While researchers have associated certain health benefits with replacing other dietary fatty acids with alpha-linolenic acid and other omega-3 fatty acids, these are scarce in most Americans' diets. Current consumption levels are likely related to concurrent knowledge, beliefs, attitudes, and other behaviors about omega-3s and fat in general. The purpose of this study was to interview and survey likely targeted...; Download File | View full details

Wireless Communication for Sparse and Rural Areas: Author: Zhang, Mingliu; Date: 2007-08-15; Program: Engineering; Abstract: Wireless technology experienced a fast development in the past few decades. However, research and investment in wireless communication so far has been focused mainly on high-density domains or fully connected networks. The technologies/solutions developed for above domains do not readily apply to rural and sparse domains. The users in rural and sparse areas are still served predominantly by either low-speed dialup access or have no data service available at all. This research work explores the largely overlooked rural and sparse domains, where distance, rough terrain and low node density are t...; Download File | View full details

Arbuscular Mycorrhizae in Yellowstone National Park Thermal Soils: Host Plant, Fungal Inoculum, Soil pH, and Elevated Temperature Effects on Symbiosis Function: Author: Bunn, Rebecca Anne; Date: 2004-08-15; Program: Land Resources and Environmental Sciences; Abstract: Arbuscular mycorrhizae (AM) are frequently described as a textbook example of a mutualistic symbiosis between a plant and fungus. However, we now understand that AM fungi are not always beneficial to their host plants. By requiring host plant photosynthate in exchange for potential benefits, the symbiosis varies along a continuum from mutualistic to parasitic. Examining AM function in extreme environments may increase our understanding of how the balance between symbionts is achieved, and if it is altered in the presence of strong abiotic stresses. Thermal soils offer a unique opportunity to s...; Download File | View full details
