Longevity Of Mineral Supplements Within The Soil And Associated Use By White-Tailed Deer, Brian C. Peterson, Keith D. Koupal, Andrew K. Schissel, Cody M. Siegel

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Humans have baited wildlife such as white-tailed deer (Odocoileus virginianus) for generations with the primary purpose of increasing hunting harvest success. Baiting regulation changes are often considered by state management agencies as they pertain to hunting opportunity, fair chase, and disease risk. Cervids require a variety of minerals to supplement biological processes, especially sodium (Na), calcium (Ca), and phosphorus (P). We developed artificial mineral supplement sites set in front of trail cameras to monitor deer use. Pooled soil samples were collected at mineral sites and compared to the surrounding area to determine the longevity of elevated minerals levels …

However, the majority of empirical research on athletic participation has been conducted on athletes and non-athletes, leaving a gap in regard to at-risk students. The study provides a comparison between athletic participation and non-participation with at-risk students. The goal of this study was to share the findings of an investigation of the impact of athletic participation on at-risk high …

The Keetch-Byram Drought Index And The Geographical Variability In Wildfire Size And Frequency In Eight Natural Areas Of The United States, Michael Tobit Gray

Theses and Dissertations

A continental-scale study of historic wildfire data within and across ecoregion provinces was conducted and geographical gradients in seasonal measures of wildfire size and frequency were observed. In the conterminous United States, western ecoregion provinces show north-south gradients in duration of season (short-to-long) and peak of season (early-to-late). Across the continent a gradient of unimodal to bimodal seasonal distributions of wildfire size and frequency was shown: western ecoregions have a single summer fire season and eastern regions have spring and late-summer fire seasons separated by an intervening dip in wildfire activity. From the ecoregion provinces with the highest wildfire frequency, …

The Relationship Between School Counselor Beliefs Regarding The Asca National Model Components And Implementation Of A Comprehensive School Counseling Program, Rachael Gwin Ammons

Theses and Dissertations

The American School Counseling Association (ASCA) created the American School Counseling National Model to guide best practices in the school setting. Professional school counselors are encouraged to implement this model in order to increase student achievement and personal/social growth through a comprehensive school counseling program.

Rational Bernoulli Functions For Solving Problems On Unbounded Domains, Velinda Remona Calvert

Theses and Dissertations

In this dissertation, a new numerical method for solving some problems on the semiinfinite domain is presented. The method is based upon the modified rational Bernoulli functions. These functions are first introduced. Operational matrices of derivative and product of modified rational Bernoulli functions are then derived and are utilized to reduce the solution of the equations to a system of algebraic equations. This method is used to solve the following problems: Lane-Emden type equations, Volterra’s population model, Blasius equation, and MHD Falkner-Skan equation. Illustrative examples are included to demonstrate the validity and applicability of the technique.

Preventing Teacher Attrition: Expert Teachers' Sources Of Stress And Coping Strategies, Katherine Damaris Garth

Theses and Dissertations

Teaching is considered to be one of the most stressful occupations (Johnson et al., 2005). Not only is the profession highly stressful, it has the highest degree of career turnover of any profession (Ingersoll, 2001). Consistent stress can lead to burnout of the profession. McCarthy et al. (2009) noted that teacher burnout can be a result of inappropriate coping resources. The purpose of this study was to investigate the sources of stress, coping strategies, and learned coping strategies among expert elementary teachers. The sources of stress and coping strategies were examined using the Social Ecological Model which allowed for sources …

Interactive Whiteboards And Tpack For Technology-Enhanced Learning: Secondary Mathematics Teachers Barriers, Beliefs, And Support Needs In One Rural School District, Shelita Mccadney Brown

Theses and Dissertations

Low-income students and blacks make up nearly half of public school students, and on nearly every indicator of educational access, particularly technology, these students have less access than white affluent students (Darling-Hammond, Zielezinski, and Goldman, 2014). The National Center for Education Statistics (2005) reported that teacher quality and missed opportunities to learn accounted for 93% of African Americans, and 87% of Hispanics performing below proficiency in mathematics. Students that do not master mathematics standards by the end of compulsory education are less likely to complete general mathematics courses in upper secondary school and beyond successfully (Levpušček, Zupančič, & Sočan, 2013). …

Groups Of Isometries Associated With Automorphisms Of The Half - Plane, Job Otieno Bonyo

Theses and Dissertations

The study of integral operators on spaces of analytic functions has been considered for the past few decades. However, most of the studies in this line are based on spaces of analytic functions of the unit disc. For the analytic spaces of the upper half-plane, the literature is still scanty. Most notable is the recent work of Siskakis and Arvanitidis concerning the classical Ces`aro operator on Hardy spaces of the upper half-plane. In this dissertation, we characterize all continuous one-parameter groups of automorphisms of the upper halfplane according to the nature and location of their fixed points into three distinct …

Recursive Model Selection For Gnss-Combined Precise Point Positioning Algorithms, Andrew Tollefson

Theses

The accuracy of Global Positioning algorithms can be improved by incorporating observations from the satellites of multiple Global Navigation Satellite Systems (GNSS). To best utilize these observations, inter-system biases must be modeled. A unified observational model is proposed which accounts for these factors for an arbitrary number of GNSS. The Bayesian Information Criterion (BIC) may be imposed upon the unified model to balance data-fitting degree with model complexity among candidate models for a given satellite configuration scenario. A simple formulation is derived for the change to the Weighted Sum Squared Residuals (WSSR) outcome caused by modifying the least-squares design matrix …

Automated Theorem Proving By Translation To Description Logic, Negin Arhami

Open Access Dissertations

Many Automated Theorem Proving (ATP) systems for different logical forms, and translators for translating different logical forms from one to another, have been developed and are now available. Some logical forms are more expressive than others, and it is easier to express problems in those logical forms. On the other hand, the ATP systems for less expressive forms have benefited from more years of development and testing. There is a trade-off between the expressivity of a logical form, and the capabilities of the available ATP systems. Different ATP systems and translators can be combined to solve a problem expressed in …

Algebraic Poetry, Julian Deville

Honors Theses

Although content has evolved in poetry at a steady pace throughout the 20th and 21st centuries, the form in which this content is presented has seen little change. In response to this apparent stagnation of form in poetry, this presentation aims to combat the enforced linearity of writing, embracing Cubist ideals, to make way for a new form of poetry- algebraic poetry. This new form may then provide new inspiration within the literary community, and a new form with which writers may move forward, as opposed to adhering to the same form for centuries. This project then uses modern algebra …

Giulianotti, Lawrence Toll

Mathematics Faculty Articles

The hypothesis in the current study is that the simultaneous direct in vivo testing of thousands to millions of systematically arranged mixture-based libraries will facilitate the identification of enhanced individual compounds. Individual compounds identified from such libraries may have increased specificity and decreased side effects early in the discovery phase. Testing began by screening ten diverse scaffolds as single mixtures (ranging from 17 340 to 4 879 681 compounds) for analgesia directly in the mouse tail withdrawal model. The “all X” mixture representing the library TPI-1954 was found to produce significant antinociception and lacked respiratory depression and hyperlocomotor effects using …

A Comparison Of Infaunal Community Structure Between Pre- And Post Construction Sampling Of Artificial Fdot Rock- Pile Reefs In Broward County, Florida, Joan Lorraine Guerra

HCNSO Student Theses and Dissertations

Artificial reefs (ARs) are generally created with the intention of increasing local fish populations, biodiversity and corresponding habitat productivity, most often in support of commercial and recreational uses (e.g., diving and fishing). Numerous studies have investigated the communities that develop on artificial reefs. By contrast, far less research has focused on the surrounding infaunal communities, which represent critical trophic resources for many species that populate both natural and artificial reefs, and which may be affected both by AR deployment and the organisms that subsequently recruit to them. This study compared infaunal organism abundances at four sites between the inner and …
