Development And Outcomes Of An Experientially-Based Nonverbal Social Skills Curriculum For Youth With Visual Impairments, Rebecca J. Cicha

Theses and Dissertations

The importance of social skills training for youth with visual impairments has been widely researched within educational and rehabilitation settings. To date, social skills training curricula for visually impaired youth have largely utilized verbally-based methods for instruction and training. Given the non-visual aspects of human communication, it is proposed that verbal approaches to nonverbal social skills training may not be sufficient for visually impaired individuals. To address this issue, an experiential curriculum of nonverbal social skills training was developed that emphasized hands-on learning and practice of nonverbal social skills. This curriculum was administered to seventeen visually impaired youth attending short-term …

Optimization Of The Garch Model Parameters Using A Genetic Algorithm, Jonathon Patrick Cummings

Theses and Dissertations

Financial time series are often characterized by nonlinearity and volatility bunching. Standard regression analysis models cannot capture changing volatilities, potentially leading to erroneous results. The need to more completely model the characteristic volatilities inherent to financial time series eventually led to the creation of the GARCH model. Typical GARCH parameters are (1,1) incorporating a 1-period lag of the regression residual as well as a 1-period lag of the regression volatility. The primary question investigated in this paper is whether the typical GARCH(1,1) parameters are in fact optimal over all time periods and attempts to improve on the typical parameters by …

Determination Of Optimum Polymer Dose For Grand Forks Wastewater Treatment Plant Lagoon Sludge Dewatering, Dipesh Das

Theses and Dissertations

The Grand Forks Waste Water Treatment Plant (GFWWTP) is currently sending its waste activated sludge (WAS) from the activated sludge treatment process to an existing on-site wastewater treatment lagoon which has been in operation since 2003. The plant produces approximately 65,000 gallons of WAS per day. Because of this high level of loading, the existing lagoon system is no longer considered as a treatment option for the produced sludge. The Plant Authority is trying to find a sustainable solution for sludge disposal and for this reason the GFWWTP is interested in introducing screw press system for the dewatering process. As …

Does Google Search Data Aid In Predicting Unemployment?, Brennan Dyk

Theses and Dissertations

The unemployment rate is typically forecasted in the literature using initial claims for unemployment, a lagged value of unemployment, and an autoregressive component. This paper looks to improve upon existing models by adding Google search data to traditional models using initial claims or replacing initial claims with Google searches. One hypothesis is that Google searches may improve forecast accuracy due to employees knowing or getting a sense when they may become unemployed and be searching for jobs prior to filing for unemployment. Study of this is important to improve the accuracy of models and to provide more accurate out-of-sample forecasts …

Seasonal Resource Selection, Site-Specific Brood Predictors, And Nest Characteristics Of Greater Prairie-Chicken Hens In Northwestern Minnesota, Nathaniel Emery

Theses and Dissertations

Greater prairie-chickens, Tympanuchus cupido pinnatus, are in decline across the majority of their already receding range due to changing land use patterns and habitat fragmentation. The Agassiz Beach Ridge region of northwestern Minnesota harbors one of the only sustained to increasing populations of prairie-chickens in the country due to the conversion of marginal agricultural lands to grasslands and through conservation entities securing tracts of land allowing for habitat stability and dispersal.

Nesting and brood-rearing habitats are the most limiting factors for population sustainability. Hens were marked with radio transmitters on booming grounds and at nest sites discovered by nest-dragging. Their …

An Investigation Of Climate Patterns On Earth-Like Planets Using The Nasa Giss Global Climate Model Ii, Robert Mark Elowitz

Theses and Dissertations

To determine the capability of NASA's GISS GCM-II global climate model, the user-friendly EdGCM interface to the 3-D climate model code was evaluated by simulating global climate patterns that Earth-like planets may experience. The simulation scenarios involved different greenhouse gas emissions trends, planetary orbital parameters, and solar irradiance variations. It is found that the EdGCM interface to the GCM-II 3-D climate model is capable of studying climate patterns on hypothetical Earth-like planets, with some limitations involved. Studying extreme climate patterns on Earth-like planets as a function of planetary obliquity, orbital eccentricity, atmospheric composition, solar irradiance variations, and location with the …

Historical Hydroclimatic Change At Theodore Roosevelt National Park: 1895 - 2011, Rhonda Jan Fietzek-Devries

Theses and Dissertations

Although numerous studies have examined hydroclimatic and climatic changes in our national parks, no previous studies have examined historical temperature, precipitation and hydroclimatic changes at Theodore Roosevelt National Park (South Unit). Documenting historical trends in temperature, precipitation and hydroclimatic variables is important for understanding present and future changes in vegetation and wildlife.

I used 117 (1895 - 2011) years of temperature and precipitation data obtained from the PRISM data network to construct the historical climatic water budget time series based upon the Thornthwaite water-budget model. Trend lines and descriptive statistics are used to analyze the monthly, seasonal and annual climatic …

Rural North Dakota's Oil Boom, The Impact On Social Services, And The Implications For The Social Work Profession, Julia C. Geigle

Theses and Dissertations

Technological developments within the oil and gas industry (namely horizontal drilling and hydraulic fracturing, or "fracking") combined with record-high average oil prices have propelled North Dakota into the midst of the nation's largest oil boom in decades. Information about the boom has been dominated by the media, while scholarly attention--especially about the social impacts--has been unfortunately limited. Accordingly, the author (an MSW student) and two professors with the Department of Social Work at the University of North Dakota conducted a focus group with the state's county social service directors to explore the pressures and challenges faced by the social service …

"Oh, Must We Dream Our Dreams And Have Them Too?": Transformation Through Reading In Elizabeth Bishop's "Questions Of Travel," Carol Shields' Swann, And Florian Henckel Von Donnersmarck's The Lives Of Others, Carissa Anne Green

Theses and Dissertations

Literary scholars study how readers interpret texts. Louise Rosenblatt, Wolfgang Iser, and Wayne Booth analyze how readers interact with texts transactionally, as a phenomenology, and as an ethical exchange. This grounding gives a foundation on which to analyze and define the interpretive acts demonstrated by readers. Poststructuralist critics Roland Barthes and Jacques Derrida open up the idea of "text," allowing us to apply our phenomenology of reading beyond words on paper. I apply the work of these and other critics not to the readers of texts but to characters depicted within texts who are readers. These characters confront unfamiliar texts, …

Microwave Tomography Using Stochastic Optimization And High Performance Computing, Michael William Holman

Theses and Dissertations

This thesis discusses the application of parallel computing in microwave tomography for detection and imaging of dielectric objects. The main focus is on microwave tomography with the use of a parallelized Finite Difference Time Domain (FDTD) forward solver in conjunction with non-linear stochastic optimization based inverse solvers. Because such solvers require very heavy computation, their investigation has been limited in favour of deterministic inverse solvers that make use of assumptions and approximations of the imaging target. Without the use of linearization assumptions, a non-linear stochastic microwave tomography system is able to resolve targets of arbitrary permittivity contrast profiles while avoiding …

The Influence Of Television And Film On Interest In Space And Science, Katrina Marie Jackson

Theses and Dissertations

Entertainment media has the great potential to inspire interest in the topics it presents. The purpose of this study is to better understand how entertainment media contributes to people's interests in space and science. There is a huge variety of science communication topics in previous literature, some of which deals with television and film, but very little that specifically study how television and film can inspire interest. A historical review of pioneers in the space industry shows that many were inspired by entertainment media, which at the time consisted of science fiction novels and magazines. In order to explore the …

Modeling Arsenic, Antimony, And Selenium Partitioning During Coal Combustion, David W. James

Theses and Dissertations

Even though greenhouse gas emissions have gained widespread recent attention, they are not the only form of pollution associated with coal. Several trace elements liberated from the coal matrix during combustion represent additional pollutants that must be understood and controlled. These elements have a variety of ways in which they are associated within coal, which impacts how they may be released into the environment. Namely, trace elements are classified as "included," "excluded," or "organically bound." Specific elements-arsenic, antimony, and selenium-are of particular interest due to their semi-volatile nature.

Modeling the partitioning of semi-volatile elements-arsenic, antimony, and selenium-is the focus of …

The Ecology Of Host-Seeking Mosquitoes Within The Red River Valley Of Central North Dakota, Joseph Orlo Mehus

Theses and Dissertations

Host-seeking mosquitoes are taxing for people and wildlife alike in the Red River Valley (RRV). During the summer massive numbers of mosquitoes swarm the RRV, yet little is known about the ecology and biology of the mosquito species that inhabit this area. This research will help to fill some of those knowledge gaps by studying the ecology of host seeking mosquitoes in the RRV.

Host-seeking mosquitoes were collected using CO₂-baited MMX^TM traps. Trapping was conducted in two very different rural settings within the RRV. One site, a 40-acre hardwood forest with closed canopy, the other a farmstead …

Utilization Of Emotional Freedom Techniques (Eft) To Reduce Test Anxiety In High Stakes Testing, Marie Elaine Mohler

Theses and Dissertations

There are many reasons a person may fail a high stakes test such as the National Council Licensure Examination for Registered Nurses (NCLEX-RN®). Sleep deprivation, illness, life stressors, knowledge deficit, and test anxiety are some of the common explanations. A student with test anxiety may feel threatened by this evaluation process. This reaction causes the students to become self-absorbed with altered cognitive abilities such as reduced ability: to concentrate, to remember, and/or to retrieve information, thus lowering the students' performance. This research study explored the correlation among factors such as stress, test anxiety, and student expectations that may be predictive …

Towards More Efficient Enhanced Sampling Methods To Study Phase Transitions, Kenneth Ndumbe Ngale

Theses and Dissertations

The most familiar phase transitions observed in nature are associated with a change in the state of matter (solid, liquid, and gas). In some rare cases this may involve the plasma phase. Such transitions are often referred to as first order phase transitions and often occur commonly such as during the melting of snow or freezing of lakes and rivers during winter. This project focuses on the most ubiquitous phase changes such as, liquid-solid and vapor-liquid as well as the less prevalent vapor-solid transitions. These types of phase transitions are also known as classical phase transitions. They usually involve symmetry …

A Model Of Nontraditional College Student Motivation And Success, Masela Anyango Obade

Theses and Dissertations

Despite the increase in their college enrollment, nontraditional students in U.S. postsecondary institutions are less likely to stay in college until they earn their degree. What could explain nontraditional student high attrition rates and overall success beyond what their demographic characteristics reveal? The purpose of this study was to examine the role of achievement motivation in predicting nontraditional student college success using the expectancy-value theory (Eccles et al., 1983) and achievement goals theory (Dweck, 1986; Maehr, 1989; Nicholls, 1984). A Model of Nontraditional College Student Motivation and Success was tested using a sample of undergraduate students enrolled in various majors …

This Is Only A Test, Laurel Lynn Perez

Theses and Dissertations

This is Only a Test, a collection of original poems, explores perception: how we view ourselves both in our everyday lives and in our obsessions. My hope is to not necessarily to critique these moments or years in our lives, but to expose them in my aesthetic project, using free verse, form, and invented form to set them against the unexpected. By using and departing from traditional poetic forms I create new ways of reading the content. In writing about themes such as fertility, relationships, sexuality, and violence I look at the places we never meant to be in view …

Role Of The Alzheimer's Amyloid Precursor Protein In High Fat Diet Induced Obesity And Regulating Macrophage Phenotype, Kendra L. Puig

Theses and Dissertations

Amyloid precursor protein (APP) derived amyloid beta peptides have been extensively investigated in Alzheimer's disease pathology of the brain. However, the function of full length APP in the central nervous system remains unclear. Even less is known about the behavior of this ubiquitously expressed protein and it metabolites outside of the central nervous system. Therefore, we sought to broaden our understanding of the expression and function of APP and its proteolytic fragments in specific non-neuronal tissues. Although the majority of research effort is currently focused on neuronal amyloid beta production and its effects on cells, prior work in our lab …

Improving The Palmer Drought Severity Index By Incorporating Snow And Frozen Ground, Shaoyue Qiu

Theses and Dissertations

Drought causes extensive damage and affects a significant number of people. To quantify the severity of drought and to better monitor drought, drought indices are necessary. The Palmer Drought Severity Index (PDSI) has its advantages of comprehensive and taking the characteristics of drought into concern so that it was regarded as the milestone in the revolution of drought indices (Heim, 2002). The PDSI has been widely used, tested, and modified since its development in 1965. However, a commonly documented limitation to this index is the lack of consideration for snow and the treatment of ground status. In this study, a …

Spirituality And Systemic Lupus Erythematosus, Kara Ann Richardson-Cline

Theses and Dissertations

Problem: The positive relationship between spirituality and physical, psychological, and social well-being has been well established. However, beyond quality of life measures, this construct has yet to be more deeply studied in a sample of individuals diagnosed with Systemic Lupus Erythematosus (SLE). Furthermore, relational spirituality has yet to be studied in a chronically ill population. Meeting these gaps in the literature, this study compared the explicit domains and latent constructs measured by a relational spirituality instrument and examined their associations with a measure of biopsychosocial-spiritual well-being and quality of life measure.

Results: Utilizing nonrandom online surveys, this study included 305 …

Moreover, the paper outlines a revenue forecast based on the price of Brent crude oil. The analysis finds that over 94% of the variability in OFITE's revenues is explained by the price of Brent oil. This information is important to OFITE owners and management if they wish to increase revenues when oil prices are flat or decreasing. A diversification strategy is one avenue owners could take to lessen …

Wendell Berry's Philosophy Of Education: Lessons From Port William, Jane Margaret Schreck

Theses and Dissertations

In the midst of a proclaimed crisis in higher education, in the clamor and clamber to leverage technology for such innovations as mass open online courses and differentiated learning modules, in the speculative frenzy of preparing students for the careers of a fantasy future, and in the swirl of angst about funding accountability and economic relevance, Wendell Berry's philosophy of education declares that the essential element missing from most current discussions and considerations of education is love. As explained in his essays and revealed in his fiction and poetry, Berry's philosophy centers on love as the best animator of learning: …

Communication Channels For Cancer Survivorship: Addressing Information Dissemination, Clinical Trial Recruitment And Social Networking, Carly Elizabeth Steen

Theses and Dissertations

More people are surviving cancer than ever before due to early detection and advances in treatment (Kazanjian, Smillie, Howard, Ward and Doll, 2009). With a growing group of cancer survivors, a group expected to grow to 18 million by 2020, additional informational resources must be put in place (Cancer Survivorship Training, 2013). This study seeks to better understand 1) where cancer patients and survivors are finding cancer resources, 2) what computer-mediated communication channels they use and prefer and 3) who they trust the most to educate and recruit them for clinical trials. Twenty in-depth interviews were conducted and analyzed with …

Influence Of Gender And Race On Self-Objectification, Kaylee M. Trottier

Theses and Dissertations

The current study examined how men's expectations and references in women's body type (the study attempts to examine the effects of men's expectations by manipulating the gender and race of the present research assistant) may affect how heterosexual women value and judge themselves. This was explored through a manipulation of the experimenter's race and gender. The researcher manipulated the experimenter's race and gender; assuming that the participants have a stereotypical expectation of what men prefer (a more slender body type) in feminine body types. The experimenters interviewed the participants on their confidence, self-esteem, and body-image. The research is important to …

The Impact Of Continuous Prenatal And Early Postpartum Maternal Vitamin D Supplementation On The Vitamin D Status Of Exclusively Breastfed Infants, Doria K. Thiele

Theses and Dissertations

In the United States, at least 50% of breastfeeding mothers are vitamin D deficient, increasing risk for vitamin D deficiency in exclusively breastfed infants. A gap in knowledge exists regarding best practices in maternal vitamin D supplementation during pregnancy and lactation that will yield adequate infant vitamin D levels. The objective of this study was to identify the combined effect of maternal prenatal and postnatal vitamin D supplementation on vitamin D transfer to exclusively breastfed infants. Additionally, due to the immune modulating effects of vitamin D, maternal pro- and anti-inflammatory cytokines were measured across pregnancy and the postpartum. A double-blind, …

Is There A Disconnect? Comparing North Dakota And National Geography Standards, Lori Jean Young

North Dakota Studies is a Grade 9-12 course offered in North Dakota high schools. This course is offered under mandate in North Dakota high schools, so a broad range of data could be obtained by contacting those teachers.

Prior research has shown that students exposed to 3-D geographic technologies have better spatial abilities than students without a technologic background. A recent study showed that adults wanted to know more about geography …

Efficient Regeneration Of Chemical Solvents For Carbon Dioxide Capture By Polymeric Membrane Contactors, Xuefei Zhang

Theses and Dissertations

Although extensive research attention has been drawn to using membranes for carbon dioxide (CO2) capture from flue gas, the use of membranes for stripping CO2 solvents has rarely been studied. The technical feasibility of using polymeric membrane based separation technology to recover CO2 from CO2 saturated chemical solvents such as monoethanolamine is investigated in the present research. A membrane system was built to study the performance of several common polymeric porous membranes for the recovery of CO2 from saturated aqueous MEA solution by the thermal swing process. The stripped CO2 gas was swept by mass flow controlled N2 reference gas …
