Atlantic Multidecadal Oscillation-Forced Regional Summertime Precipitation Variations In The Central United States, Michael C. Veres

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

The purpose of this research is to identify the regional mechanisms by which the Atlantic Multidecadal Oscillation (AMO) influences summer (June-August) precipitation in the central U.S. This was accomplished by running two different sets of simulations using the Weather Research and Forecasting (WRF) regional climate model, one forced by observations and the other forced only by variations in the AMO as obtained via a global climate model (GCM). The results reveal a complex set of mechanisms active in the lower and middle troposphere by which the AMO influences summer circulation and precipitation in the central U.S. During the cold phase …

Effective Science Teachers’ Professional Development: A Multiple-Case Study Of District-Level Science Supervisors’ Perspectives, Chris J. Schaben

College of Education and Human Sciences: Dissertations, Theses, and Student Research

At its heart, science teachers’ professional development is about continual growth and improvement (Yager, 2005). Conducting research to understand what constitutes effective professional development is inherently complex (Hewson, 2007). The imperative to link research on professional development to student achievement (Fishman, Marx, Best, & Tal, 2003) increases complexity of research on the topic. These complexities require multiple research approaches and indicate that all stakeholders could provide insights to identify what constitutes effective professional development. District-level science supervisors’ voices are missing from the data on effective science teachers’ professional development and this provides a potential gap in the literature (Banilower, Heck, …

Inquiry, Art And Consummatory Experience: A Deweyan Account Of The Instrumental And Aesthetic Modes In Human Well-Being, Eric A. Evans

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This dissertation argues that a Deweyan reconstruction of philosophical theories of human well-being is needed. While philosophical interest about human well-being has existed for millennia, significant interest in such theories among philosophers has re-emerged during the past twenty-five years. During this same time there has been a resurgence of interest in the work of John Dewey. His critique of the “philosophical fallacy” is used to examine the legitimacy and value of the theories of human well-being offered by Plato and L.W. Sumner in which the target for evaluation is “happiness” and the criterion is, respectively, P-justice or preference fulfillment. It …

The findings in study 1 revealed six prominent categories that inform women’s alcohol expectancy. Findings in study 2 provided 7-subscales (α > 0.7) for the instrument’s reliability and validity. Additionally, there were significant differences in alcohol expectancy by genders. Implications related to expectancy theory …

Community College Faculty Perspective On Changing Online Course Management Systems: A Phenomenological Inquiry, Kathleen Eitzmann

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This is a phenomenological research study about a college that is changing course management systems for online courses and the experiences that the full-time faculty go through during the transition from one course management system (CMS) to another.

Colleges are seeing a student enrollment shift away from the traditional classroom toward the online environment. This demand in online learning means colleges have to offer more online courses, train more faculty, and support the technological requirements of online learning. Many colleges purchase a course management system to support their online courses. When a college changes the course management system, faculty must …

Examining The Effect Of Medical Risk, Parental Stress, And Self-Efficacy On Parent Behaviors And The Home Environment Of Premature Children, Kathryn Woods

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The purpose of this study was to examine the relationship between medical risk and parenting stress and the extent to which parental self-efficacy moderates the relationship between medical risk, parenting stress, specific parenting behaviors (i.e., parental responsivity, acceptance of child, parental involvement) and the home environment (i.e., organization of environment, learning materials, variety in experience, and IT-HOME total score) of premature children. Participants included 72 parent-child dyads with premature children between the ages of 7 and 35 months corrected age. Measures included parent reports of medical risk, stress, self-efficacy, and the IT-HOME. Results show that medical risk was not significantly …

“The Grin Of The Skull Beneath The Skin:” Reassessing The Power Of Comic Characters In Gothic Literature, Amanda D. Drake

Department of English: Dissertations, Theses, and Student Research

Neither representative of aesthetic flaws or mere comic relief, comic characters within Gothic narratives challenge and redefine the genre in ways that open up, rather than confuse, critical avenues. Comic characters in the Gothic texts of Horace Walpole, Ann Radcliffe, and Clara Reeve establish the comic as a serious and legitimate part of the Gothic aesthetic. Comic characters continue to appear in all forms of the Gothic, including its parodies, well into the nineteenth-century, suggesting that these characters endure as necessary and vital elements within the evolving Gothic genre. As the genre evolves, the characters evolve as well, progressing from …

Adaptation And Validation Of Food Product Specific Analytical Methods For Monitoring Prebiotics Present In Different Types Of Processed Food Matrices, Rebbeca M. Duar

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Prebiotic carbohydrates are now added to a variety of processed foods to beneficially affect the gut microbial composition and activities. However, published data remain limited on the stability of prebiotics during food processes, such as baking, extrusion, pasteurization, high temperature heating, low pH condition, etc. As the complexity of the food matrix may also affect the ability to test for prebiotics, product specific analytical methods, including UV-vis spectroscopy, GC and HPLC, were developed and validated to monitor the stability of FOS, inulin and GOS in different types of processed food (breakfast cereal, cookie, muffin, sports drink and a nutritional bar). …

Quantum Mechanical And Molecular Mechanical Study Of Solvent Effects, Dejun Si

Department of Chemistry: Dissertations, Theses, and Student Research

Intermolecular interaction and solvent effects play important roles in determining physical and chemical properties of molecular systems, and must be considered in relevant quantum mechanical (QM) calculations. Due to the high computational cost, full and rigorous QM treatment of both solute and solvent molecules is impractical. Computationally efficient molecular mechanical (MM) methods can be used to describe solvent effects, and combined into QM methods to formulate QM/MM methods. Classical force field method and reaction-field method are the two most popular MM methods. However, the issue of effectively combining MM methods with high-level QM methods remains unsolved. This thesis presents several …

Management Zone Delineation Techniques On Irrigated Corn In Nebraska, Aaron M. Bereuter

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Increased interest in site-specific management of irrigated corn in Nebraska has identified the need for a decision-making framework for zone delineation. Zones based on static soil and landscape properties provide a valuable foundation for variable rate management strategies. The purpose of this project was to identify the optimal soil and landscape attributes for generating management zones (MZ) of relative productivity potential. Three producer-managed cornfields across Nebraska with varying soil types, topographic characteristics, and climate regimes were identified as research sites during the 2010 growing season. Nine soil and landscape attributes were identified as potential properties for estimation of productivity potential. …

Fundamental Rights In Latin America A Comparative Study Addressing Human Rights Violations In Venezuela, Colombia, And Argentina, Maria Eugenia Rios

HIM 1990-2015

Over the last few decades the importance of human rights has increased considerably in international relations. With globalization and democratization, more states and individuals develop concerns about the fundamental rights every human is entitled to; regardless of sex, religion and ethnicity. Latin American countries began obtaining their independence over 200 years ago while progressing into becoming working democracies. Yet, they have been plagued by oscillating authoritarian regimes and social conflicts that constrain and inhibit their hopeful development. The majority of the Latin American states have reached a point where further positive growth was expected; yet human violations have taken a …

Rand Takes On The Constitution An Objectivist Perspective Of The United States Constitution, Farin C. Robinson

HIM 1990-2015

Author and philosopher Ayn Rand has gathered a cult like following thanks to her bestselling novels We the Living, Anthem, The Fountainhead and Atlas Shrugged. Through Rand's fictional writings she illustrates the principles of her philosophy objectivism. Objectivism employs five principles; objective reality, reason, self -interest, capitalism and individualism as the truths that govern the philosophy. Objectivists believe that their self-reliant philosophy holds the key to all life's answers. This thesis examines the following question: what would the founder of objectivism Ayn Rand think about the U.S. Constitution? Sadly Ayn Rand passed away in 1982 and never expressed her full …

Improving Eyewitness Testimony Methods For More Accurate Recall Of Events, Ashley M. Schachter

HIM 1990-2015

Eyewitness testimony has as long history in the court system, and is very persuasive to juries. Jurors are hard pressed to ignore a witness' assertion of a perpetrator's identity. However, the juror's perception of eyewitness testimony is problematic as it has been documented as inaccurate and unreliable in numerous experiments. With the advent of DNA testing and efforts such as The Innocence Project, it has become apparent that faulty eyewitness accounts are central to many wrongful convictions. The intent of this thesis was to explore how law enforcement can facilitate more accurate eyewitness accounts via their interview process. Research suggests …

An Examination Of The Fraudulent Factors Associated With Corporate Fraud, Ronald Zmuda

HIM 1990-2015

Between the years 1998 and 2002, the United States suffered a time in which several large companies engaged in fraudulent behavior which eroded investor confidence in the stock market and to some extent destabilized the economy. Audits, which were conducted to assess the validity and reliability of a company's financial statements, were not detecting the material misstatements in the statements. As a result, both the US Government and the accounting profession needed to come up with a way to prevent these immense frauds from occurring in the future. As a response to these large frauds, in 2002, the US Government …

Spatial Ability And Experts Of Needlework Crafts An Exploratory Study, Shannon Kyle Tedder Bailey

HIM 1990-2015

In the Surface Development Test, self-perceived Sewing Expertise was significant in predicting participants' test scores. For the Paper Folding Test, Knitting and Crocheting Expertise were significant, suggesting expertise may mitigate age effects.; Spatial ability has been a topic of much research and debate over the past few decades. Yet, there are gaps in the current literature. Spatial ability refers to the aptitude of an individual to mentally rotate objects, visualize spaces, and recognize patterns (Linn & Petersen, 1985). A highly spatial task that is not addressed in research literature is crafting. Crafting may refer to knitting, crocheting, sewing, and other …

Gold Nanoparticle Generation Using In Situ Reduction On A Photoresist Polymer Substrate, Christopher J. Clukay

HIM 1990-2015

This report presents evidence that in-situ reduction of metal ions bound to a cross-linked polymer surface does not always result in nanoparticle formation solely at the interface, as is commonly assumed, but also as much as 40 nm deep within the polymer matrix. Tetrachloroaurate ions were bound using a variety of multi-functional amines to cured films of SU-8 -- a cross-linkable epoxide frequently used for micro- and nanofabrication -- and then treated using one of several reducing agents. The resulting gold-nanoparticle decorated films were examined by X-ray photoelectron spectroscopy and by plan-view and cross-sectional transmission electron microscopy. Reduction using sodium …

Human Resources: A Key Aspect In Company Innovation, Kristin Hall

HIM 1990-2015

Innovation is a key factor for companies. It is also essential on an individual scale for employees. To ensure they are utilizing employees to the utmost efficiency, companies must implement practices to ensure the attraction and retention of top employees. Human resource practices can help to define and explain essential techniques to help employees gain satisfaction from their work, creating intrinsic motivation, and allowing them to ultimately perform more efficiently and perhaps even creatively for the company, helping to generate significant profits. The intent of this thesis is to analyze human resource practices on an empirical study of eight companies …

Art Teacher Preparation Does The Path To Certification In Florida Matter?, Deanna Jean Price

HIM 1990-2015

For years now, students have been learning from two different types of teachers: Teachers who received certification from a traditional training program at a university and teachers who became certified through alternative certification routes. Does the educational preparation of an art teacher matter? Is alternative certification as effectual as traditional teacher preparation programs? Darling- Hammond (2006) says, "Evidence indicates that teachers who have had more preparation for teaching are more confident and successful with students than those who have had little or none." This thesis will examine and analyze alternative teacher certification in art education for the state of Florida, …

Sufficient Conditions For Uniqueness Of The Weak Value, Justin Dressel, Andrew N. Jordan

Mathematics, Physics, and Computer Science Faculty Articles and Research

We review and clarify the sufficient conditions for uniquely defining the generalized weak value as the weak limit of a conditioned average using the contextual values formalism introduced in Dressel, Agarwal and Jordan (2010 Phys. Rev. Lett. 104 240401). We also respond to criticism of our work by Parrott (arXiv:1105.4188v1) concerning a proposed counter-example to the uniqueness of the definition of the generalized weak value. The counter-example does not satisfy our prescription in the case of an underspecified measurement context. We show that when the contextual values formalism is properly applied to this example, a natural interpretation of the …

Investigation Of A Novel Method For Polonium-210 Determination In Groundwater, Tara Matheny

All Theses

A novel method was investigated for the quantification of 210Po in water as an alternative to the standard method of spontaneous plating onto Ag disks followed by quantification with an alpha spectrometer. The novel method concentrated a 0.5L sample by MnO2 co-precipitation followed by dissolution of the precipitate into a solution. Polonium-210 was separated from the solution and quantified in a column containing a 50:50 by volume mixture of Pb resin (Eichrom Technologies, Inc.) mixed with granulated CaF2:Eu scintillator. The column containing 210Po is quantified on a liquid scintillation counter without the introduction of liquid cocktail. The minimum detectable concentration …

Fabrication Of All-Inorganic Nanocrystal Solids Through Matrix Encapsulation Of Nanocrystal Arrays, Erich Kinder, Pavel Moroz, Geoffrey Diederich, Alexa Johnson, Maria Kirsanova, Alexander Nemchinov, Timothy O’Connor, Dan Roth, Mikhail Zamkov

Physics and Astronomy Faculty Publications

A general strategy for low-temperature processing of colloidal nanocrystals into all-inorganic films is reported. The present methodology goes beyond the traditional ligand-interlinking scheme and relies on encapsulation of morphologically defined nanocrystal arrays into a matrix of a wide-band gap semiconductor, which preserves optoelectronic properties of individual nanoparticles while rendering the nanocrystal film photoconductive. Fabricated solids exhibit excellent thermal stability, which is attributed to the heteroepitaxial structure of nanocrystal matrix interfaces, and show compelling light-harvesting performance in prototype solar cells.

Local Television Coverage Of A Mall Shooting: Separating Facts From Fiction In Breaking News, Jeremy Harris Lipschultz, Michael L. Hilt

Communication Faculty Publications

Local TV news emphasizes the earliest stage of crimes because ‘‘breaking news’’ is fresh, dramatic and visual. A qualitative analysis was conducted using a comprehensive set of recordings of the first three-and-a-half hours of local television news coverage in Omaha, Nebraska. This study identified a series of ongoing issues that have important implications for newsroom decision-makers. Local television news used charged and dramatic language, such as that shooting victims were ‘‘fighting for their lives.’’ Reporters and news managers find themselves in the middle of a struggle between two options: remaining a distant and objective observer of events, or connecting with …

Brief Assessment Of Schizotypy: Developing Short Forms Of The Wisconsin Schizotypy Scales, Beate P. Winterstein, Paul J. Silvia, Thomas R. Kwapil, James C. Kaufman, Roni Reiter-Palmon, Benjamin Wigert

Psychology Faculty Publications

The Wisconsin Schizotypy Scales—the Perceptual Aberration, Magical Ideation, Physical Anhedonia, and Revised Social Anhedonia Scales—have been used extensively since their development in the 1970s and 1980s. Based on psychometric analyses using item response theory, the present work presents 15-item short forms of each scale. In addition to being briefer, the short forms omit items with high differential item functioning. Based on data from a sample of young adults (n = 1144), the short forms have strong internal consistency, and they mirror effects found for the longer scales. They thus appear to be a good option for researchers interested in …
