Sexual Fluidity And Women's Bisexual Identity Development, Julijana Draganic

Theses and Dissertations

Experiences of bisexual and sexual fluid women are poorly explored and understood in the current literature. While there is a need and interest in the exploration of bisexual experiences in the current literature, these experiences are usually lumped together with the experiences of lesbian women, who are vastly overrepresented in the participant samples. Data was collected from LGBT centers, women's centers, bisexual interest listservs, and sexual minority internet groups. This study examined: the relationship between a measure of fluidity in attractions, the Sexual Fluidity Grid (SFG) and a measure of sexual orientation, the Klein Sexual Orientation Grid; the relationship between …

Variations Of E-Region Total Electron Content And Electron Density Profiles Over High Latitudes During Winter Solstice 2007 Using Radio Occultation Measurements, Kajli Agrawal

Theses and Dissertations

The space weather phenomenon involves the Sun, interplanetary space and the Earth. Different space weather conditions have diverse effects on the various layers of the Earth's atmosphere Technological advancements have created a situation in which human civilization is not only dependent on resources from deep inside the Earth, but also on the upper atmosphere and outer space region. Therefore, it is essential to improve the understanding of the impacts of space weather conditions on the ionosphere. This research focuses on the variation of total electron content (TEC) and the electron density within the E-region of the ionosphere, which extends from …

The Effect Of Birth Order On Age At First Sex And Total Number Of Lifetime Sexual Partners, Lacey Christine Clark Anderson

Theses and Dissertations

Research in the field of birth order is expansive and has been used to explain many social processes, including the sexual behavior of young adults. However, results regarding the influence of birth order on risky sexual behavior are somewhat limited, sometimes contradictory, and often lack generalizability to larger populations. In this thesis, using

data from the National Health and Social Life Survey (1992) and multiple regression techniques, I investigate the influence of ordinal position on two measures of sexual behavior,age at first sex and total number of lifetime partners, among young adults age 18 to 30. Results show that birth …

Josephson Currents In Two-Gap Superconductor-Insulator- Superconductor Junctions, Ladan Bahrainirad

Theses and Dissertations

As a way to investigate the transport property of superconductor-insulator-superconductor (SIS) junction with two-gap superconductors such as MgB2 and iron superconductors, we study the microscopic structure of the Josephson current in a tunnel junction with a very narrow quasi-classical barrier. Also, the possibility of mid-gap states in two-gap superconductor is investigated, and their effects on the current-phase relation as well as the current density characteristics are studied. In the SIS break junction, mid-gap states appear at the Superconductor-Insulator interfaces due to an abrupt change in the superconducting order parameter, indicating that the two-gap superconductor SIS junction can yield a rich …

Effects Of Paid Maternity Leave On The Gender Wage Gap, Rachel Baxter

Theses and Dissertations

The persistence of the gender wage gap in countries throughout the world has sparked several theories as to its cause and possible solutions. One theory centers on the decisions faced by a woman regarding children and fertility throughout her career. Typically, as the primary caregivers for children, women are more likely to interrupt their careers or leave the labor force entirely as a result. This thesis uses a fixed-effects model using a panel dataset of 18 countries with observations from 2000 to 2010 to evaluate whether paid maternity leave has an effect on the breadth of the gender wage gap. …

Exploring The Differences In Deep Convective Transport Characteristics Between Quasi-Isolated Strong Convection And Mesoscale Convective Systems Using Seasonal Wrf Simulations, Brandon Clifford Bigelbach

Theses and Dissertations

It has been shown in several previous studies that there is a relationship between mesoscale storm type and deep convective mass transport characteristics. For example, a previous simulation study showed that a supercell storm transported significantly more

tracers into the stratosphere than did a multicell storm in an environment with identical thermodynamic structure. We utilize the Weather Research and Forecasting (WRF) model (version 3.2.1) with chemistry to simulate mass transport during the convective season of 2007 in the U.S. Southern Great Plains at convection-resolving scale (2 km). The storms that were resolved in the model were then classified using an …

Characterization Of Evaporative Metal Bonding In Superalloys For Use In Gasified Coal Turbine Generators, Joshua Elliot Braband

Theses and Dissertations

The diffusion bonding of Kanthal APMT, CM247LC, and Rene 80 was studied. The objective of the first part of this work was to create diffusion bonded test samples of Kanthal APMT, CM247LC, and Rene 80 using a 25μm thick zinc interlayer at varying times and temperatures. Then, using scanning electron microscopy to determine the profile of the zinc diffusing into the parent materials, the diffusion coefficients of the zinc interlayer into the materials were determined for each of the materials at each bonding time and temperature. The next objective was to create a finite element model of the bonding process …

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 …

Development Of Second Generation Rolling Contact Fatigue Tester, Satyam Ulhas Deshmukh

Theses and Dissertations

Contact fatigue failure has been in research since the early twentieth century. The need for a second generation sliding-rolling contact fatigue tester was proposed by Gregory Dvorak and Dr. Marcellin Zahui. The first generation RCF tester was used for testing super finishing processes for gear surfaces. The second generation RCF tester was funded by the Advanced Engineering Materials lab of University of North Dakota.

Verification of the second generation Rolling Contact Fatigue Tester will be discussed in this thesis including the design details, assembly and testing procedure and to discuss its different parameters. The tester will have the capability of …

Position Control Of Electro-Hydraulic Actuator System Using Fuzzy Logic Controller Optimized By Particle Swarm Optimization, Daniel M. Wonohadidjojo, Ganesh Kothapalli, Mohammed Hassan

Research outputs 2014 to 2021

The position control system of an electro-hydraulic actuator system (EHAS) is investigated in this paper. The EHAS is developed by taking into consideration the nonlinearities of the system: the friction and the internal leakage. A variable load that simulates a realistic load in robotic excavator is taken as the trajectory reference. A method of control strategy that is implemented by employing a fuzzy logic controller (FLC) whose parameters are optimized using particle swarm optimization (PSO) is proposed. The scaling factors of the fuzzy inference system are tuned to obtain the optimal values which yield the best system performance. The simulation …

A Dynamic Perspective On Affect And Creativity, Ronald Joachim Bledow, K. Rosing, M. Frese

Research Collection Lee Kong Chian School Of Business

We argue that creativity is influenced by the dynamic interplay of positive and negative affect: High creativity results if a person experiences an episode of negative affect that is followed by a decrease in negative affect and an increase in positive affect, a process referred to as an “affective shift.” An experience-sampling study with 102 full-time employees provided support for the hypotheses. An experimental study with 80 students underlined the proposed causal effect of an affective shift on creativity. We discuss practical implications for facilitating creativity in organizations.

Reference Point Adaptation And Disposition Effect, Chiraphol New Chiyachantana, Zongfei Yang

Research Collection Lee Kong Chian School Of Business

This paper investigates the importance of reference point adaptation in the analysis of the disposition effect. We consider two exogenous factors pertinent to reference point adaptation: prior outcome and recent expectation of future outcome. We show that the incidence of the disposition effect varies in a manner consistent with reference point adaptation. Both prior outcome and recent expectation of future outcome affect the location of the reference point and have a large and significant impact on the incidence of the disposition effect. First, the disposition effect can largely be explained by investors’ inability to sufficiently adapt the reference point in …

Career Path Trends Of Alumni From A U.S. Tesol Graduate Program, Mark W. Tanner, Eimi Priddis, Lynn E. Henrichsen, Ben Warner, Neil J. Anderson, Dan P. Dewey

Faculty Publications

As English expands across the world, quality English teachers are increasingly needed. However, reports that even degree-holding TESOL professionals have a hard time obtaining stable employment are prevalent. This study sought to provide empirical evidence about career paths in TESOL based on survey responses from 250 alumni of a well-established U.S. university TESOL graduate program who had successfully completed their course of study and had worked during a 35-year period since the program’s inception.

The results indicate that TESOL graduates spend about half of their career time in TESOL-related employment. Most are involved in teaching, but jobs in administration, materials …

Elucidating Satisfaction With Physical Activity: An Examination Of The Day-To-Day Associations Between Experiences With Physical Activity And Satisfaction During Physical Activity Initiation, Scott A. Baldwin, Austin Baldwin, Valerie G. Loehr, Julie L. Kangas, Georita M. Frierson

Faculty Publications

Satisfaction with physical activity is known to be an important factor in physical activity maintenance, but the factors that influence satisfaction are not well understood. The purpose of this study was to elucidate how ongoing experiences with recently initiated physical activity are associated with satisfaction. Participants (n = 116) included insufficiently active volunteers who initiated a self-directed physical activity regimen and completed daily diaries about their experiences for 28 days. We used multilevel models to examine the associations between experiences with physical activity and satisfaction. Significant between-person effects demonstrated that people reporting higher average levels of positive experiences and lower …

In an effort to identify an automated means of updating and standardizing metadata within a digital collection, the University of Utah's Marriott Library and Backstage Library Works partnered to develop a service that would replicate the benefits of an automated MARC21 authority control project for digital library metadata. This paper will discuss how the process to update MARC21 bibliographic records was adapted to update data encoded in XML. Future directions for this project will include taking a close look at how it can be used to link URIs with strings of data in order to prepare for a linked data …

Syllabification Of American English: Evidence From A Large-Scale Experiment. Part I, Dirk Elzinga, David Eddington, Rebecca Treiman

Faculty Publications

4990 bi-syllabic English words were syllabified by about 22 native speakers who choose between different slash divisions (e.g. photon: FOW/TAHN, FOWT/AHN). Results of the regression analyses of the items with one medial consonant are discussed. Consistent with previous studies, consonants were drawn to stressed syllables, and more sonorant consonants were more often placed in the coda. A model in which syllables are made to be as word-like as possible is supported; syllables were often created that begin and end in the same phonemes that are legal word-initially and finally, and syllabifications tended to follow morpho-logical boundaries. Orthographic conventions, such as …

The Effect Of Information Disclosure On Information Asymmetry, Chiraphol New Chiyachantana, Neeranuch Nuengwang, Nareerat Taechapiroontong, Pakpoom Thanarung

Research Collection Lee Kong Chian School Of Business

This study investigates the relation among information disclosure, firm characteristics and information asymmetry. The authors find evidence consistent with the notion that increasing corporate disclosure and transparency reduces the asymmetric information between informed and uninformed investors. The findings indicate a strong relation between firm characteristics and level of information disclosure. Larger firms, firms with high growth opportunity and superior performance are associated with higher level of information disclosure. With respect to type of information, large firms, firms with superior operating performance, high growth opportunity are likely to disclose the investment and structural change as well as legal and miscellaneous information. …

The Archaeology Of Archaeology: 2012 Excavations At Alkali Ridge Site 13, James R. Allison

Faculty Publications

Alkali Ridge Site 13 is one of the largest, and most extensively excavated Pueblo I villages in the Northern Southwest. It also is one of the earliest Pueblo I villages, dating to the late A.D. 700s. The site was first excavated in 1932 and 1933 by J.O. Brew of Harvard University, who dug all or part of 118 storage rooms, 11 pit houses, and 25 surface habitation rooms belonging to the early Pueblo I component. In 2012, the first excavations at the site since Brew’s work focused on reexcavation of several storage rooms previously excavated in 1932, screening of backdirt …

Accessories Of Modern Mayan Grinding Stones, Michael T. Searcy

Faculty Publications

The mano and metate are seen as natural companion pieces in the archaeological record. Ethnographic resources suggest there may have been other tools associated with daily grinding activities including biconically drilled (donut) stones and wooden boards. This paper presents evidence for these findings and explores their archaeological implications. It also demonstrates the valuable information that can be gleaned from the modern Mayan groups living in Highland Guatemala today.

Social Network Development, Language Use, And Language Acquisition During Study Abroad: Arabic Language Learners’ Perspectives, Dan P. Dewey, R. Kirk Belnap, Rebecca Ann Hillstrom

Faculty Publications

Language learners and educators have subscribed to the belief that those who go abroad will have many opportunities to use the target language and will naturally become proficient. They also assume that language learners will develop relationships with native speakers allowing them to use the language and become more fluent, an assumption Pellegrino (Pellegrino, 1997, 1998) found to be held by study abroad participants. However, recent research has shown that students do not always use the language to the expected degree and that they often fall back on social relationships with native speakers of their own language (DeKeyser, 2007; Dewey, …

Cathedral Of Kairos: Rhetoric And Revelation In The “National House Of Prayer”, Richard Benjamin Crosby

Faculty Publications

Traditionally, kairos is defined by its transience. Scholars assume that in order to capitalize on the rhetorical power of kairos, a speaker must capture the “opportune moment” before it passes. his article makes the case that the kairic moment can be sustained indefinitely through the sacralization of physical space. Linking rhetorical theories of kairos as “God’s time” to Mircea Eliade’s discussion of “sacred hierophanies,” the article performs an analysis of the National Cathedral in Washington DC and concludes that rhetoric can circumvent traditional contingencies when deployed within kairic space.

Oath Rhetoric, Political Identity, And The Case Of Jon Huntsman, Richard Benjamin Crosby

Faculty Publications

Oath rhetoric took center stage during the 2011-2072 presidential campaign, particularly during the Republican primary races. Several conservative organizations invited candidates to sign pledges, vows, or, as I label them collectively, oaths in an effort to secure the candidates' allegiance to particular polices and communities. Through a close concept-oriented analysis of a representative artifact (the Pro-Life Presidential Leadership Pledge) and candidate Jon Huntsman's refusal to sign it, this essay concludes that oaths serve important rhetorical functions at the personal, cultural, and political level. Whereas traditional political argument in the democratic tradition is meant lo create openings for action, oath rhetoric …

Review: "Of Africa", Aaron Eastley

Faculty Publications

“A truly illuminating exploration of Africa,” suggests Wole Soyinka in the preface of his new book, Of Africa, “has yet to take place.” Soyinka is not writing here of a physical exploration, of course, but of a humanistic or spiritual one. This, at the root, is what the eight essays that comprise Of Africa urge readers to consider: ways in which Africa can lead the world forward into “a deeply craved Age of Universal Understanding.” In Soyinka’s estimation Africa today is very nearly as misapprehended and undervalued by the world at large as ever it was in the past. But …

Love, Hate, Ambivalence, Or Indifference? A Conceptual Examination Of Workplace Crimes And Organizational Identification, Abhijeet K. Vadera, Michael G. Pratt

Research Collection Lee Kong Chian School Of Business

Although research has shown that there may be very different types of workplace crimes, scholarly work in this area (a) is currently fragmented with very little communication between very similar streams of research and (b) tends to be incomplete and can lead to conflicting findings. We address both of these shortcomings. First, we propose a typology of different types of workplace crimes (consisting of pro-organizational, nonaligned-organizational, and anti-organizational crimes) based on the intentions of the perpetrators. Second, we link these intentions to various identification "pathologies"- such as over-identification and over-disidentification, under-identification and ambivalent identification-and argue that these pathologies are linked …
