Characteristics And Accessibility Of Loaner Programs Used By Missouri String Teachers, Juliana Marie Georgiades Jan 2015

Characteristics And Accessibility Of Loaner Programs Used By Missouri String Teachers, Juliana Marie Georgiades

Graduate Theses/Dissertations

The purposes of my study were (a) to describe string instrument loaner programs and associated administrative practices in socioeconomically diverse schools and (b) to analyze the accessibility of string education with respect to school size and socioeconomic status. The research involved the responses to an electronic survey completed by 42 Missouri K-12 string teachers who taught at 119 schools spanning 20 school districts. Findings suggest that lower income schools were more likely to have students using school-owned instruments as their only instrument, more likely to not use loaner instruments that were shared between schools, and more likely to lack the …

Bodies Bending Boundaries: Religious, Spiritual, And Secular Identities Of Modern Postural Yoga In The Ozarks, Kimberley J. Pingatore Jan 2015

Bodies Bending Boundaries: Religious, Spiritual, And Secular Identities Of Modern Postural Yoga In The Ozarks, Kimberley J. Pingatore

Graduate Theses/Dissertations

Modern postural yoga is an amalgamation of practices that continues to defy traditional explanatory models that understand religious, spiritual, and secular to be mutually exclusive categories. In this project, I conduct in-depth interviews with yoga instructors in the Ozarks. In these interviews, I asked my informants to explain how they understand religious, spiritual, and secular. I then asked if and how they would use those words to describe yoga. These interviews revealed that religious, spiritual, and secular are not mutually exclusive, but are instead related, blended, and connected, especially when used to describe yoga. These findings inform my proposed explanatory …

To Fidget Or Not To Fidget: The Effect Of Movement On Cognition, Kelsey Diane Grodner Jan 2015

To Fidget Or Not To Fidget: The Effect Of Movement On Cognition, Kelsey Diane Grodner

Theses and Dissertations

Previous research suggests that there is controversy regarding the effects of fidgeting. On one hand, fidgeting has been associated with inattention. On the other hand, the act of suppressing movement may have extensive costs to cognitive abilities. Thus, allowing fidgeting might be beneficial for attention. However certain fidgeting behaviors, such as large body movements, might be disruptive in certain situations, like a classroom or an office meeting. Fidget toys have been developed that allow for smaller fidgeting movements that are non-disruptive. Most previous studies have been conducted in an elementary school classroom and have used primarily observational data. Here we …

Closing Time And Cheerleader Effects Are Moderated By Target Value, Jackie R. Mcdowell Jan 2015

Closing Time And Cheerleader Effects Are Moderated By Target Value, Jackie R. Mcdowell

Theses and Dissertations

Previous research on factors influencing evaluations of mate value has revealed seemingly contradictory results. Specifically, the Closing Time Effect predicts that individuals will be viewed as more attractive when there are fewer individuals to choose from, while the Cheerleader Effect predicts that individuals will be viewed as more attractive when they are in the presence of others. The current study evaluates the influence of baseline measures of attractiveness on each of these effects. Results indicate that low value individuals may be more subject to Closing Time Effects, while high value individuals benefit from the Cheerleader Effect. The influence of mating …

Role Of Student Entitlement And Co-Production On Satisfaction, Deborah Jean Sisson Jan 2015

Role Of Student Entitlement And Co-Production On Satisfaction, Deborah Jean Sisson

HCBE Theses and Dissertations

The marketing of services has challenges uncommon to that of marketing products. By nature service offerings are intangible, heterogeneous, perishable, and simultaneously consumed and produced. This simultaneous consumption and production often requires the consumer to participate in the service delivery – co-production. Colleges and universities offer a service which requires high levels of co-production by students and is the setting for this research. As colleges/universities face greater challenges at this time, there is a need for better understanding of the role the student plays in the production process. The service marketing literature offers an understanding of the importance of the …

Can Social Stories Lead To An Improved Theory Of Mind Amongst Individuals With Autism?, Margaret Rose Lorenzetti Jan 2015

Can Social Stories Lead To An Improved Theory Of Mind Amongst Individuals With Autism?, Margaret Rose Lorenzetti

Theses and Dissertations

This thesis investigated whether Social Stories used in conjunction with perspective- taking questions would lead to an improved Theory of Mind (ToM) in three participants diagnosed with Autism Spectrum Disorder (ASD). We assessed participants’ perspective taking in a baseline condition, implemented a Social Story condition, and tested participants’ perspective taking again in a post-intervention condition. ToM was assessed using two variations of the false belief measures, namely the change-location and unexpected-contents paradigms. Each Social Story included three perspective-taking questions that required participants to infer a character’s emotion or perspective. Results indicated that participants’ percentage scores of correct responses increased markedly …

Conductive Patterns By Spray Pyrolysis Of A Self-Reducing Copper-Amine Complex Ink, Phenfar Benjapongvimon Jan 2015

Conductive Patterns By Spray Pyrolysis Of A Self-Reducing Copper-Amine Complex Ink, Phenfar Benjapongvimon

Chulalongkorn University Theses and Dissertations (Chula ETD)

A conductive pattern prepared by spray pyrolysis of copper-amine complex ink on glass and polyimide (PI) substrates in nitrogen atmosphere. The complex ink was prepared by mixing copper (II) formate, diethanolamine, 25% ammnonia solution and distilled water. The effects of concentration of copper ion, spray pyrolysis temperature, annealing time, type of substrate, rate of deposition and benzimidazole coating were investigated. Concentration of copper ion affected size of copper particles generated. The patterns fabricated at 200 OC had higher packing density than those fabricated at lower temperature. The rate of deposition determined the thickness of well-sintered layer. Therefore, volume resistivity of …

A Study Of Uplift Capacity Of Pipeline In Soils, Khamnoy Kounlavong Jan 2015

A Study Of Uplift Capacity Of Pipeline In Soils, Khamnoy Kounlavong

Chulalongkorn University Theses and Dissertations (Chula ETD)

This thesis aims to analyze the uplift capacity of a burial pipeline in two types of soil namely cohesionless soils and cohesive-frictional soils. Finite element analysis with two dimensional plain strain condition were employed to model and determine the limit load of this problem. Cohesionless and cohesive-frictional soils were model as Mohr-coulomb materials in the drained condition while a pipeline was modeled as plate element with an elastic material with high axial and bending stiffness to ensure its rigid behavior. Parametric studies of cohesionless soils and cohesive-frictional soils were performed to study effects of dimensionless variables, including 1) embedment depth …

Prospects For Detection Of Extragalactic Stellar Black Hole Binaries In The Nearby Universe, Matthew Benacquista, Jesus Hinojosa, Alberto Mata, Krzysztof Belczynski Jan 2015

Prospects For Detection Of Extragalactic Stellar Black Hole Binaries In The Nearby Universe, Matthew Benacquista, Jesus Hinojosa, Alberto Mata, Krzysztof Belczynski

Physics & Astronomy Faculty Publications

Stellar mass black hole binaries have individual masses between 10-80 solar masses. These systems may emit gravitational waves at frequencies detectable at Megaparsec distances by space-based gravitational wave observatories. In a previous study, we determined the selection effects of observing these systems with detectors similar to the Laser Interferometer Space Antenna by using a generated population of binary black holes that covered a reasonable parameter space and calculating their signal-to-noise ratio. We further our study by populating the galaxies in our nearby (less than 30 Mpc) universe with binary black hole systems drawn from a distribution found in the Synthetic …

Understanding The Gravitational-Wave Hellings And Downs Curve For Pulsar Timing Arrays In Terms Of Sound And Electromagnetic Waves, Fredrick A. Jenet, Joseph D. Romano Jan 2015

Understanding The Gravitational-Wave Hellings And Downs Curve For Pulsar Timing Arrays In Terms Of Sound And Electromagnetic Waves, Fredrick A. Jenet, Joseph D. Romano

Physics & Astronomy Faculty Publications

Searches for stochastic gravitational-wave backgrounds using pulsar timing arrays look for correlations in the timing residuals induced by the background across the pulsars in the array. The correlation signature of an isotropic, unpolarized gravitational-wave background predicted by general relativity follows the so-called Hellings and Downs curve, which is a relatively simple function of the angle between a pair of Earth-pulsar baselines. In this paper, we give a pedagogical discussion of the Hellings and Downs curve for pulsar timing arrays, considering simpler analogous scenarios involving sound and electromagnetic waves. We calculate Hellings-and-Downs-type functions for these two scenarios and develop a framework …

Detection Of Temporal Changes In Vegetative Cover On South Padre Island, Texas Using Image Classifications Derived From Aerial Color-Infrared Photographs, Ruben A. Mazariegos, Kenneth R. Summy, Frank W. Judd, Robert I. Lonard, James H. Everitt Jan 2015

Detection Of Temporal Changes In Vegetative Cover On South Padre Island, Texas Using Image Classifications Derived From Aerial Color-Infrared Photographs, Ruben A. Mazariegos, Kenneth R. Summy, Frank W. Judd, Robert I. Lonard, James H. Everitt

Physics & Astronomy Faculty Publications

Supervised image classifications developed from 23 x 23 cm aerial color-infrared aerial photographs (1:5,000 scale) were used to evaluate temporal changes in vegetative cover occurring within three 150 x 300-m research sites on South Padre Island, Texas. Use of high-resolution digitized imagery (ground pixel resolution of ca. 0.1 m) and survey-grade GPS for positional measurements of ground control points (20-25 1.0m2 targets within each research site) resulted in consistently high levels of geometric accuracy, with root mean square errors (RMSEs) ranging between 0.397 – 2.867. Similarly, use of relatively simple information categories (dry and wet sand, live and dead vegetative …

Lateral Migration Of The Red River, In The Vicinity Of Grand Forks, North Dakota, Dylan Babiracki Jan 2015

Lateral Migration Of The Red River, In The Vicinity Of Grand Forks, North Dakota, Dylan Babiracki

Undergraduate Theses and Senior Projects

River channels are dynamic landforms that play an important role in understanding the alluvial changes occurring within this area. The evolution of the Red River of the North within the shallow alluvial valley was investigated within a 60 river mile area north and south of Grand Forks, North Dakota. Despite considerable research along the Red River of the North, near St. Jean Baptiste, Manitoba, little is known about the historical channel dynamics within the defined study area. A series of 31 measurements were taken using three separate methods to document the path of lateral channel migration along areas of this …

Regolith Erosion At Grinnell Glacier, Glacier National Park, Montana, Connor Devon Lindenberg, Jaakko Putkonen Jan 2015

Regolith Erosion At Grinnell Glacier, Glacier National Park, Montana, Connor Devon Lindenberg, Jaakko Putkonen

Undergraduate Theses and Senior Projects

Glacier National Park is located within a mountainous region in western Montana. Due to recent glaciation, moraines are present at the upper elevations throughout the park. These young moraines erode at a rapid pace when first exposed by melting ice due to: age, vegetation cover, local climate, and human/animal activity. Using repeat photography in conjunction with lab work I was able to determine that the Grinnell Glacier moraine’s crest is lowering at a much faster pace than previously published rates. Conservation policy within the park should be adjusted to reflect this information and additional research should be conducted to determine …

One-Dimensional Triple Periodic Dual-Beam Microstrip Leaky-Wave Antenna, Zi Long Ma, Li (Lijun) Jun Jiang Jan 2015

One-Dimensional Triple Periodic Dual-Beam Microstrip Leaky-Wave Antenna, Zi Long Ma, Li (Lijun) Jun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

In this letter, a novel dual-beam microstrip leaky-wave antenna based on one-dimensional triple periodic (TP) structure is proposed. Through theoretical dispersion relation analysis, it is found that compared to the conventional periodic structure, TP structure has reduced the separation of space harmonics. Hence, more space harmonic modes are brought into the leaky-wave radiation region. Through proper design, m = - 1 and m = - 2 modes are excited simultaneously. Consequently, the forward and backward propagation waves of these two modes generate two radiation beams in the far-field region. At different frequencies, symmetrical and asymmetrical beam pairs are realized. It …

Pausing At The Threshold, Patrick K. Morgan Jan 2015

Pausing At The Threshold, Patrick K. Morgan

Faculty Publications

Threshold concepts are increasingly inescapable at library conferences and in general information literacy discourse, and this visibility will likely only increase as they figure so prominently in the Association of College and Research Libraries inchoate Framework for Information Literacy for Higher Education. Nevertheless, very little has been done to critically consider the wider intellectual ramifications of certain assumptions fundamental to their manifestation in library/information literacy instruction. This paper is an initial attempt to promote such discussions.

We have measured the radial light profiles and global shapes of bars using two-dimensional 3.6μm image decompositions for 144 face-on barred galaxies from the Spitzer Survey of Stellar Structure in Galaxies. The bar surface brightness profile is correlated with the stellar mass and bulge-to-total (B/T) ratio of their host galaxies. Bars in massive and bulge-dominated galaxies (B/T > 0.2) show a flat profile, while bars in less massive, disk-dominated galaxies (B/T ∼ 0) show an exponential, disk-like profile with a wider spread in the radial profile than in the bulge-dominated galaxies. The global two-dimensional shapes of bars, however, are rectangular/boxy, independent …

Do Depressive Symptoms Predict The Incidence Of Myocardial Infarction Independent Of Hopelessness?, Patrick Pössel, Amanda M. Mitchell, Kimmo Ronkainen, George A. Kaplan, Jussi Kauhanen, Maarit Valtonen Jan 2015

Do Depressive Symptoms Predict The Incidence Of Myocardial Infarction Independent Of Hopelessness?, Patrick Pössel, Amanda M. Mitchell, Kimmo Ronkainen, George A. Kaplan, Jussi Kauhanen, Maarit Valtonen

Faculty and Staff Scholarship

Depression and hopelessness predict myocardial infarction (MI), but it is unclear whether depression and hopelessness are independent predictors of MI incidents. Hopelessness, depression, and MI incidence rate 18 years later were measured in 2005 men. Cox regressions were conducted with hopelessness and depression serving as individual predictors of MI. Another Cox model examined whether the two predictors predict MI when adjusting for each other. Depression and hopelessness predicted MI in independent regressions but when adjusting for each other, hopelessness, but not depression, predicted MI incidents. Thus, these results suggest that depression and hopelessness are not independent predictors of MI.

Developing A Chronic Pain Vocabulary: Communication Preferences Among Individuals With Chronic Pain, Karin L. Becker Jan 2015

Developing A Chronic Pain Vocabulary: Communication Preferences Among Individuals With Chronic Pain, Karin L. Becker

Theses and Dissertations

In order to be acknowledged, chronic pain must be voiced yet disclosing of chronic pain is fraught with social and professional repercussions. Moreover, there is a perceived disinterest in hearing about, and a stigma associated with the experience of chronic pain. This research explores the therapeutic value of communicating about pain. Nineteen individuals with chronic pain participated in a six-week online writing workshop to describe the way chronic pain impacts daily activities. These qualitative responses were analyzed using discourse analysis and four interpretive repertoires emerged which convey the multi-faceted impacts of living with chronic pain. These findings informed the creation …

Characterization Of Newly Synthesized Cobalt Polypyridine Complexes Using Nmr, X-Ray, Electrochemistry, And Uv-Vis, Blaise Frenzel

Theses and Dissertations

Coordination of the 2,6-bis(8′-quinolinyl)pyridine (bqp) ligand to a cobalt (Co) core and its influence to electron spin and configuration on the structures and properties of the resulting complexes has been investigated. The homoleptic complexes [Co(mer-bqp-κ3N,N′,N″)2][PF6]2 (1) and [Co(mer-bqp-κ3N,N′,N″)2][Br3]3 (2) were prepared and characterized. X-ray structure determinations of complexes 1 and 2 revealed twisted, near-octahedral arrangements relative to the cobalt center. The magnetic data for 1 is typical of those for distorted octahedral (i.e., D4h symmetry) high-spin d7 species despite the near-ideal octahedral coordination of the bqp ligand around the Co(II) core. Electronic spectra for 1 and 2 have been investigated …

Investigation Of Lanthanide-Doped Anatase Tio2 Core-Shell Nanoparticles For Photocatalysis And Gas Sensing, Rezwanur Rahman Jan 2015

Investigation Of Lanthanide-Doped Anatase Tio2 Core-Shell Nanoparticles For Photocatalysis And Gas Sensing, Rezwanur Rahman

Graduate Theses/Dissertations

Anatase TiO2 has been shown to be potential applications for photo-remediation of chemical waste as well as for photocatalytic splitting of water. The catalytic properties of TiO2 materials can be modified by doping with lanthanide (Ln) ions. In order to minimize the distortion and/or change of the structure of TiO2 nanoparticles, surface doping of anatase TiO2 nanoparticles (~ 14 nm) with several Ln ions (Nd3+, Gd3+, Eu3+, Yb3+) has been successfully made. X-ray diffraction (XRD) and Raman characterization shows that the anatase phase of treated nanoparticles is well preserved. Scanning electron microscopy (SEM) shows that the majority of the nanoparticles …

Aspects Of Fourier Analysis On Euclidean Space, Joseph William Roberts Jan 2015

Aspects Of Fourier Analysis On Euclidean Space, Joseph William Roberts

Graduate Theses/Dissertations

The field of Fourier analysis encompasses a vast spectrum of mathematics and has far reaching applications in all STEM fields. Here we introduce and study the Fourier transform and Fourier series on Euclidean space. After defining the Fourier transform, establishing its basic properties, and presenting some classical results we looked into what impact the smoothness of a function has on the growth and integrability of its Fourier transform. This endeavor also involved a brief study of Bessel functions and interpolation of operators. Having established several results indicating that the behavior of a function's Fourier transform is largely dictated by the …
