Psychometric Properties Of Postsecondary Students' Course Evaluations, Michael J. Drysdale

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Several experts in the area of postsecondary student evaluations of courses have concluded that they are stable or reliable measures as well as being measures that provide ways of making valid inferences regarding teacher effectiveness. Often these experts have offered these conclusions without supporting evidence. Surprisingly, a thorough review of the literature revealed very few reported test-retest reliability studies of course evaluations and the results from these studies are contradictory. In the area of validity, the conclusions offered by scholars who conducted meta-analyses of mutlisection course studies are inconsistent. This leads to the following two research questions:

1. What is …

Utah Kindergarten Teachers' Challenges And Concerns About Teaching Kindergarten, Ruth Jane Liebschutz Moore

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This qualitative study was an exploration of 55 Utah kindergarten teachers' perceptions of challenges in teaching. It investigated written concerns teachers expressed in a statewide survey of kindergarten teachers. Study findings indicated that two main issues were communicated by teachers: a disparity between their developmentally appropriate beliefs and practices in the classroom, and concerns about children's kindergarten readiness and transition to school. About 56% of teachers felt a struggle in implementing their developmentally appropriate beliefs about education, for a variety of reasons: large class sizes, district and state mandates, and lack of resources, particularly time. Furthermore, 53% of educators conveyed …

Environmental And Developmental Indicators In Early Childhood: Relations To Second-Grade Reading Comprehension, Gina A. Cook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Reading success has been linked to high school completion, future job success, and future generations of children who can read. Unfortunately, children who are unable to read on grade level by the end of first grade are at a great disadvantage and unlikely to catch up later. Without the ability to read and comprehend text, all aspects of schooling become progressively more difficult and the challenge of poor reading ability can be so difficult to overcome that many poor readers will not complete high school. For these reasons, it is important to identify early experiences in a child's family environment …

Two methods are used: a linear approximation method and the Runke-Kutta …

Axisymmetric Finite Element Modeling For The Design And Analysis Of Cylindrical Adhesive Joints Based On Dimensional Stability, Paul E. Lyon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The use and implementation of adhesive joints for space structures is necessary for incorporating fiber-reinforced composite materials. Correct modeling and design of cylindrical adhesive joints can increase the dimensional stability of space structures. The few analytical models for cylindrical adhesive joints do not fully describe the displacement or stress field of the joint.

A two-dimensional axisymmetric finite element model for the design and analysis of adhesive joints was developed. The model was developed solely for the analysis of cylindrical adhesive joints, but the energy techniques used to develop the model can be applied to other types of joints as well. …

Learning-Based Fusion For Data Deduplication: A Robust And Automated Solution, Jared Dinerstein

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis presents two deduplication techniques that overcome the following critical and long-standing weaknesses of rule-based deduplication: (1) traditional rule-based deduplication requires significant manual tuning of the individual rules, including the selection of appropriate thresholds; (2) the accuracy of rule-based deduplication degrades when there are missing data values, significantly reducing the efficacy of the expert-defined deduplication rules.

The first technique is a novel rule-level match-score fusion algorithm that employs kernel-machine-based learning to discover the decision threshold for the overall system automatically. The second is a novel clue-level match-score fusion algorithm that addresses both Problem 1 and 2. This unique solution …

Native Bunchgrass And Invasive Weed Establishment In Low Nutrient Rangeland Soils With Nitrogen And Phosphorus Manipulation, Jeffrey S. Burnham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Competition between native perennial grasses and Bromus tectorum has been studied for many years. Recently, soil nutrients have been immobilized in an effort to preferentially inhibit growth of B. tectorum relative to native species. Most of this work has focused on soil N, but interactions with soil P are less studied and may be important as well. Additionally, although competitive effects and nutrient responses of several Centaurea spp. are well documented, data are lacking on the competitive effects that Centaurea virgata exerts on the establishment of native and exotic communities. A field experiment and a greenhouse experiment were conducted to …

Statistical Analysis Of The Usu Lidar Data Set With Reference To Mesospheric Solar Response And Cooling Rate Calculation, With Analysis Of Statistical Issues Affecting The Regression Coefficients, Troy Alden Wynn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Though the least squares technique has many advantages, its possible limitations as applied in the atmospheric sciences have not yet been fully explored in the literature. The assumption that the atmosphere responds either in phase or out of phase to the solar input is ubiquitous. However, our analysis found this assumption to be incorrect. If not properly addressed, the possible consequences are bias in the linear trend coefficient and attenuation of the solar response coefficient.

Using USU Rayleigh lidar temperature data, we found a significant phase offset to the solar input in the temperatures that varies ±5 years depending on …

Spatial Light Dilution As A Technique For Conversion Of Solar Energy To Algal Biomass, Daniel J. Dye

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A photobioreactor has been designed and developed to efficiently utilize solar irradiance through spatial dilution of sunlight. The concept of spatial light dilution is simple: incident sunlight is spread over a large surface area, thus reducing the photon flux density of the light. The implementation of this technique, however, is difficult. The reactor described within uses a new approach to spatial light dilution, utilizing recently-developed optical components to diffuse concentrated sunlight inside an algae culture. Preliminary productivity tests indicate a 2-3 fold increase in productivity per unit aperture (sunlight collection area) over a control reactor with direct-sunlight. Aperture productivity of …

The Essential Structure Of Compulsive Buying: A Phenomenological Inquiry, Letty Workman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

While many jokes and sales of specialty merchandise have been made that make light of consumers who frequently shop and buy (e.g., "When the going gets tough, the tough go shopping," or "I am a shopaholic"), for 18 million Americans suffering from compulsive buying, the process of shopping and buying has caused their lives to literally go out of control. The outcomes of this disease for individuals, families, and business are all negative. In a marketing era of social responsibility, if marketers either knowingly or unknowingly encourage increased consumption among compulsive buyers, potential negative outcomes stand to impact others well …

Plasticity And Damage In Bimodal Grain Size Al-5083: Microstructural Finite Element, Steven Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bimodal and nanocrystalline aluminum alloys are being investigated as stronger replacements for conventional polycrystalline aluminum alloys. Higher strengths are achieved by reducing the grain size of a metal; however, as the grain size is reduced the ductility diminishes. One solution that limits this decrease in ductility is the addition of a few microcrystalline grains into a nanocrystalline alloy, creating a bimodal microstructure that offers a better balance of strength and ductility. Two- and three-dimensional microstructural finite element (FE) simulations of monotonic and fatigue failures in Al-5083 having bimodal grain structures are conducted. To reduce the computational time and facilitate the …

Assessment And Performance Of Vsn-Inv Normalization On The Nci-60 Microrna Expression Profiles., Martin T. Disibio

Electronic Theses and Dissertations

Multiple normalization methods have been proposed for the analysis of microRNA microarray expression profiles but there is no consensus method. One of the more robust methods, quantile normalization, is commonly used in transcript (mRNA) studies and was therefore used for normalizing the first microRNA expression profiles of the NCI-60 cell panel, published in 2007. In this study the appropriateness of VSN-Inv, a recently proposed alternative normalization method, to the NCI-60 dataset is verified. VSN-Inv normalization results in much increased inter-sample correlations among control groups, and significantly higher intra-chip correlations of duplicate probes, versus quantile and no normalization. Furthermore, VSN-Inv normalization …

Assurance And Frustration : From Ireland And The Netherlands To Jamestown., Keith A. Donahoe

Electronic Theses and Dissertations

English experience gained from colonization attempts in the New World and in Ireland, as well as military expeditions to the European continent and the New World, helped make Jamestown more successful than any previous English colonial venture in the New World up to that time. Jamestown's early leadership successfully applied the collective English experiences from the Netherlands and Ireland to help the Jamestown colony survive. English experiences in Ireland were instrumental in developing the concepts that led to successful English colonization of North America, but English experiences in the Netherlands also played an important role. In the critical first two-and-a-half …
