Cationic Latex Nanoparticles In Electrokinetic Chromatography: Synthesis, Characterization, And Application To The Separation Of Explosives, Julie Rebecca Mcgettrick

Graduate Student Theses, Dissertations, & Professional Papers

Electrokinetic chromatography (EKC) is a powerful analytical technique that uses the instrumentation of capillary electrophoresis (CE) and the principles of chromatography to separate ionic and neutral analytes. A capillary is filled with background electrolyte (BGE), and when a voltage is applied ionic species migrate to the electrodes. Neutral compounds have no mobility, so a pseudo-stationary phase (PSP) is added to the BGE that consists of an ionic group to provide mobility and a hydrophobic group to interact with analytes. Analytes interact with the PSP which changes their apparent mobilities, leading to a separation. It is possible to coat the negatively …

Limited Evidence For Co2-Related Growth Enhancement In Northern Rocky Mountain Pinus Contorta Populations: Trends In Growth And Intrinsic Water-Use Efficiency Across Climate Gradients, Charlotte C. Reed

Graduate Student Theses, Dissertations, & Professional Papers

Forests sequester large amounts of carbon annually; however, the degree to which enhanced forest productivity is due to more conducive climate or CO₂ fertilization remains uncertain. Increasing atmospheric CO₂ may enhance photosynthesis and/or decrease stomatal conductance thereby enhancing intrinsic water use efficiency (iWUE). While increasing iWUE has been observed in most trees globally, this increase does not necessarily translate into greater growth. This study aims to evaluate whether responses of radial growth and iWUE to increasing CO₂ vary across climatic gradients. To investigate interactions between climate and CO₂ and their impacts on tree physiology and growth, …

Subjective Experience Of Empathy In Schizotypy Elicited By Literary Fictional Narrative, Christa "Anahata" Neuman

Graduate Student Theses, Dissertations, & Professional Papers

The elaborate and multidimensional systems that are involved in the personal and subjective experience of empathy are largely unexplored. Nevertheless, when empathy is measured as a static trait there is considerable evidence that individuals diagnosed with schizophrenia and schizotypy demonstrate altered and reduced empathic abilities respectively (Thirioux, 2014). The aim of this study was to investigate the effect that the context of reading literary fiction has on a portion of the process of empathic responding in relation to schizotypal traits, taking into consideration personal factors including current mood. A new measure for the use of momentary assessment of empathy was …

Moving Toward A Holistic Menstrual Hygiene Management: An Anthropological Analysis Of Menstruation And Practices In Western And Non-Western Societies, Sophia A. Bay

Graduate Student Theses, Dissertations, & Professional Papers

Educating girls is not only their human right, but also proposed as one of the best investments for improving quality of life in developing countries (Montgomery et al. 2016, 2). Although menstruation is a universal, biological process, it is fraught with cultural stigmas and taboos throughout Western and non-Western societies. Menstrual-related absenteeism is believed to be a primary cause of missed attendance and early dropout rates, so the developing field of menstrual hygiene management (MHM) is seeking to understand and evaluate what factors are contributing to these findings. After the analyzation of the current literature, a more holistic, nine-pronged approach …

Violence, Catastrophe, And Agency In Nepal: A Deeper Understanding Of The 2015 Earthquakes And Border Blockade, Kassandra D. Viers

Graduate Student Theses, Dissertations, & Professional Papers

In 2015, Nepal was struck by two catastrophes. First, on April 25, a 7.8 magnitude earthquake, followed by hundreds of aftershocks, struck in Gorkha. Then, in September, a blockade was formed that prevented goods from passing through trade checkpoints between India and Nepal. Both of these events highlight social suffering, a form of suffering that refers to the systems of oppression, unequal distribution of resources, and broad social structures that serve to keep certain people impoverished and subjugate. The earthquake caused the most damage to vulnerable people, people already suffering the effects of structural violence. The blockade was created by …

Growth Response Of Whitebark Pine (Pinus Albicaulis) Regeneration To Thinning And Prescribed Burn Release Treatments, Molly L. Mcclintock Retzlaff

Graduate Student Theses, Dissertations, & Professional Papers

Whitebark pine (Pinus albicaulis Engelm.) plays a prominent role throughout high-elevation ecosystems in the northern Rocky Mountains. It is an important food source for many birds and mammals, as well as a major player in high-elevation watershed maintenance, both slowing snowmelt and stabilizing soils. Whitebark pine is vanishing from the landscape due to three main factors – white pine blister rust (Cronartium ribicola) invasions, mountain pine beetle (Dendroctonus ponderosae) outbreaks, and successional replacement by more shade-tolerant tree species historically controlled by wildfire. In the past century, human activity such as fire suppression has altered these …

Steamed: Examinations Of Power Struggles On The Value Forum, Richard E. Babb

Graduate Student Theses, Dissertations, & Professional Papers

This study examines Valve Corporation’s Steam gaming forum to understand how members constitute meaning and overcome perceived system abuses. By going outside the system, into what could be called the meta-system, users augment their power within a Steam’s structure where they are in a lower power position. Using qualitative analysis and structurating activity theory as a sensemaking mechanism, two incidents involving developer-user conflict were analyzed. The examination found how users were incorporating outside systems into Steam to create a system network they could use against developers. Also, several instances of systemic contradiction were found and defined. This paper expands upon …

Exploring Population Change Detection By Monitoring Effective Number Of Breeders, Brian Trethewey

Graduate Student Theses, Dissertations, & Professional Papers

Detecting if a population is in decline is an important objective for biologists and conservationists who are monitoring threatened populations. As genetic methods improve effective population size (N_e) and effective number of breeders (N_b) continue to gain popularity as a way to monitor species. Using simulated populations and linkage disequilibrium, we explored detecting population decline through N_b in age structured populations. Through comparisons of sensitivity (1 – false negatives) and specificity (1- false positives) over 1000 replicates, we explored how factors such as starting N_b, number of SNPs, number of individuals …

Universal Depression Screening In Student Health Centers Across U.S. College Campuses: Prevalence And Characteristics Associated With Use, Ivie English

Graduate Student Theses, Dissertations, & Professional Papers

Universal depression screening at university student health centers can increase identification and treatment of depression among college students, but the rates of screening in these settings were, until now, unknown (Shepardson & Funderburk, 2014). The U.S. Preventive Services Taskforce (USPSTF), American College Health Association, and other organizations have recommended that all primary care settings universally screen for depression, provided that necessary supports are in place (USPSTF, 2016; ACHA, 2010). Notably, others disagree (Joffres et al., 2013; Mitchell et al., 2009; Gilbody et al., 2005). An online survey was electronically mailed to 493 college health center directors and/or medical directors of …

Potentially Dangerous Enemy Aliens: Experiences At Fort Missoula And Transformative Immigration Policy In The United States, Daniel Smith

Graduate Student Theses, Dissertations, & Professional Papers

In this paper, I attempt to comprehend the experiences of Italian and Japanese internees who were detained at Fort Missoula’s Alien Detention Center during World War II. Furthermore, I draw upon historical patterns of United States’ immigration policies that greatly affected perspectives and social values between various ethnic groups. Simultaneously, national immigration policies shifted across space and time reflecting ethnocentric ideals and discriminatory campaigns that altered past cultural, political, and economic landscapes. The events that produced the internment of Italian and Japanese men at Fort Missoula varied greatly and are critical to examine through historical records. Such records pertain to …

Carrying The Seeds: Adaptations And Transitions Of Hmong American Food Producers In Missoula County, Montana, Rachel Cramer

Graduate Student Theses, Dissertations, & Professional Papers

Forty years after the initial resettlement of Hmong refugees in Missoula County, Montana, the Hmong American community has undergone significant agricultural and cultural adaptations. Today, there are about 200 Hmong Americans in the county, less than 2% of the population (US Census Bureau 2010), but they make up around 40% of the farmers’ market produce vendors. The thesis demonstrates that, while agriculture has played a central role in helping Hmong refugees adapt, its role is becoming more symbolic as the second generation develops an identity less connected to growing and selling food. Through a qualitative research approach using 19 in-depth …

Chillisource Game Engine Particle System Study, Angela Gross

Graduate Student Theses, Dissertations, & Professional Papers

The majority of modern game engines utilize intricate objects called particle systems which are a collection of many particles that together represent an object without well-defined surfaces. This thesis discusses the results of studying and stressing particle systems within ChilliSource, an open-source game engine written in C++, with the goal of understanding a complex system and exploring possible optimizations that could be made to it. The studies performed were driven by metrics generated with custom profiling classes that kept track of things like the number of particles rendered, how long the engine spent rendering particles, or even how long a …

Cyber-Victimization And Delinquency: A General Strain Perspective, Ian D. Greenwood

Graduate Student Theses, Dissertations, & Professional Papers

This study examines juvenile delinquency and cyber-victimization from a general strain perspective. General strain theory provides a model where strain is experienced through the (1) loss of something valued, (2) the presentation of noxious stimuli, or (3) the inability to achieve valued goals. As a coping mechanism for strain, some juveniles react through criminal or delinquent behavior. This thesis predicts that cyber-victimization increases the likelihood of physical fighting, weapon-carrying, and truancy at school. Using the 2013 National Crime Victimization Survey: School Crime Supplement, the hypotheses are analyzed using multivariate logistic regression models that include other known correlates of delinquency. Marginal …

A Comparison Of Course Quality Surveiy Results From Students On Gender Balanced And Gender Imbalanced Field Courses At Nols, Alexandra M. Alway

Graduate Student Theses, Dissertations, & Professional Papers

There is an extensive database of literature about diversity in outdoor Environmental Education and any of the studies focus on NOLS specifically. Several studies have investigated the impact of course composition in terms of gender as well as socioeconomic diversity; however, the research studies about course composition and gender were limited to differences between single gender and coed groups. The role of gender ratios on coed groups has not been widely researched. This study was designed to fill this gap in the research literature. Using course quality survey data, results showed that the student responses were significantly different between gender …

Exploring Park Support: A Study Of Philanthropy And Other Support For Yellowstone National Park, Geoffrey G. Havens

Graduate Student Theses, Dissertations, & Professional Papers

Support for charitable causes has long been a topic studied in the hopes of uncovering the reasons for donations and other support behaviors. However, holistic examination of support for places, such as parks, has been relatively untouched as an area of research. One such place where understanding such support is important is Yellowstone National Park, the first designated National Park and one of the most visited parks in the United States. A lack in adequate government funding to meet increasingly heavy visitation has led the park to increasingly rely on outside support for the park.

The purpose of this study …

Synthesis Of Satellite Microwave Observations For Monitoring Global Land-Atmosphere Co2 Exchange, Lucas Alan Jones

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation describes the estimation, error quantification, and incorporation of land surface information from microwave satellite remote sensing for modeling global ecosystem land-atmosphere net CO₂ exchange. Retrieval algorithms were developed for estimating soil moisture, surface water, surface temperature, and vegetation phenology from microwave imagery timeseries. Soil moisture retrievals were merged with model-based soil moisture estimates and incorporated into a light-use efficiency model for vegetation productivity coupled to a soil decomposition model. Results, including state and uncertainty estimates, were evaluated with a global eddy covariance flux tower network and other independent global model- and remote-sensing based products.

Hydraulic Conductivity As A Proxy For Drainage System Connectivity In A Subglacial Hydrology Model, Jacob Z. Downs

Graduate Student Theses, Dissertations, & Professional Papers

The link between subglacial hydrology and basal sliding has prompted work on basal hydrology models with water pressure and storage as prognostic variables. We find that a commonly used model of distributed drainage through linked cavities underpredicts winter water pressure when compared to borehole observations from Issunguata Sermia in Western Central Greenland. Possible causes for this discrepancy including unrealistic model inputs or unconstrained parameters are investigated through a series of modeling experiments on both synthetic and realistic ice sheet geometries. We find that conductivity acts as a proxy for the connectivity of the linked cavity system and should therefore change …

Queen Of Kings: Beyoncé Politics And Pedagogy In The Juvenile Detention Center Classroom, Sarah Kahn

Graduate Student Theses, Dissertations, & Professional Papers

In 2016, the cultural conversation around feminism and intersectionality has shifted towards new problems of inclusion and change. Feminists are beginning to ask whether the commodification of female sexuality and objectification are extricable, whether a hypersexualized mainstream identity and a feminist one are mutually exclusive, how to integrate female experiences of different socioeconomic backgrounds, races, and cultures into a new feminism, and how to define feminism as we begin to move away from binary gendering. Increased visibility of trans issues has brought genderqueerness and femmephobia into the feminist conversation, and technology and globalization have forced that conversation to open up …

Dogs Are Expensive: Cost-Benefit Perspectives On Canid Ownership At Housepit 54, Bridge River, British Columbia, Ben B. Chiewphasa

Graduate Student Theses, Dissertations, & Professional Papers

The presence of dogs in the Housepit 54 (HP 54) faunal assemblage of the Bridge River site (EeRl4) raises questions regarding their roles within Canadian Plateau prehistory, specifically their contributions to networked household economies. Ethnohistoric sources often cite dogs as “jacks of all trades,” household entities that can act as beasts of burden, hunters, prized companions, or as a husbanded food resource. The 2012-2014 field seasons yielded variation in dog frequencies throughout 10 superimposed floors (IIj-IIa); these fluctuations occurred alongside changing densities of ungulates and salmon remains. The thesis incorporates multivariate analyses to determine how dogs could have allowed HP …

“The Most Poisonous Of All Diseases Of Mind Or Body”: Colorphobia And The Politics Of Reform, April J. Gemeinhardt

Graduate Student Theses, Dissertations, & Professional Papers

Focusing on the mid-1830s through 1865, this thesis explores colorphobia—the irrational fear and hatred of black people otherwise known as racial prejudice—as a reform tactic adopted by abolitionists. It argues that colorphobia played a pivotal role in the radical abolitionist reform agenda for promoting anti-slavery, immediate emancipation, equal rights, and black advancement. By framing racial prejudice as a disease, abolitionists believed connotations, stigmas, and fears of illness would elicit more attention to the rapidly increasing racial prejudice in the free North and persuade prejudiced white Americans into changing their ways. Abolitionists used parallels to cholera, choleraphobia (fear of cholera), and …
