Movement Ecology Of An Intercontinental Migratory Bird During Spring Stopover, Emily Beth Cohen

Dissertations

Movement ecology is a component of nearly all aspects of animal behavior and an animal’s decision to move is likely influenced by a complex combination of exogenous and endogenous factors. Therefore, an examination of the causes and consequences of organismal movement provides a conceptual framework for understanding complex behavioral strategies. My dissertation research is focused on the movement ecology of an intercontinental migratory songbird during spring migration. I adopted experimental approaches to study the factors influencing how a songbird migrant, red-eyed vireos (Vireo olivaceus), makes decisions in unfamiliar landscapes from the initiation of spring stopover.

I simulated the …

Establishing Construct Validity Of The Biology I Subject Area Testing Program In Mississippi, Christy Michelle Hollis Philippoff

Dissertations

Science education has undergone many revisions since it was permanently embedded in the country's educational curriculum at the end of the 19th century. Some of these revisions occurred as a direct result of the No Child Left Behind Act (NCLB). This legislation placed more accountability on schools than ever before by requiring that all students pass a series of standardized tests (USDE, 2010). High schools in Mississippi require four areas of standardized testing: English II, Algebra I, U.S. History, and Biology I (Wroten, 2008). The focus of this study is the Biology I Subject Area Test.

In an effort to …

A Quantitative Study Of Learning In The School Cafeteria Using Educational Placemats, Keshia Lasha Gaines

Dissertations

This study investigated if there was a difference in student achievement after participants were exposed to educational placemats in a school cafeteria for four days each (four different placemats). Also, the student’s gender and ability grouping was considered in relation to achievement. This study included 49 ability grouped third grade students in an elementary school in south Mississippi. Students were pre-tested with researcher-made math instruments before the educational placemats were introduced and post-tested afterwards. For research purposes, some placemats served as a control and did not relate to the pre-test and post-test content. Statistical measurements of the differences were derived …

Behavioral Cues Associated With Lies Of Omission And Of Commission: An Experimental Investigation, Brianna Ratliff

Dissertations

Deception is a universal communication behavior across and within species. In humans, the purpose of verbal deception, or lying, is to intentionally mislead, and this behavior can be intuitively broken down into two unique categories based on the method used to mask the truth: omission and commission. Lies of omission involve the intentional exclusion of important information, whereas lies of commission involve the intentional generation of false information. Because these two types of deception involve contrasting methods of delivery, it is possible that lies of omission and lies of commission could result in differing behavioral presentations. Accordingly, the purpose of …

Evolution, Terror Management Theory, And Humans’ Relationship With Nature, Joshua Warren Vinocour

Dissertations

This study investigated the savannah hypothesis, an evolutionary explanation for human environmental preference. It aimed to address some of the methodological shortcomings of prior research while simultaneously investigating the role of non-evolutionary influences, such as existential anxiety and individual differences. Ninety-eight undergraduate participants were shown photos of Natural, Mixed, and Built settings and rated the visual attractiveness of each photo. Results showed that Built scenes were preferred over Natural and Mixed scenes, in contradiction to the savannah hypothesis. Existential anxiety, however, did not appear to influence photo ratings. Individual differences, such as ethnicity and the quality participants’ previous outdoor experiences …

Geometric Structures On Matrix-Valued Subdivision Schemes, James J. Smith

Dissertations

Surface subdivision schemes are used in computer graphics to generate visually smooth surfaces of arbitrary topology. Applications in computer graphics utilize surface normals and curvature. In this paper, formulas are obtained for the first and second partial derivatives of limit surfaces formed using 1-ring subdivision schemes that have 2 by 2 matrix-valued masks. Consequently, surface normals, and Gaussian and mean curvatures can be derived. Both quadrilateral and triangular schemes are considered and for each scheme both interpolatory and approximating schemes are examined. In each case, we look at both extraordinary and regular vertices. Every 3-D vertex of the refinement polyhedrons …

Functional Characterization Of Putative Non-Specific Phospholipase C (Npc) In Arabidopsis Thaliana, Carlotta Antonetta Peters

Dissertations

Abstract Phospholipases are enzymes that hydrolyze phospholipids. In terms of the position of bond hydrolysis, phospholipases are classified into four major types: phospholipase C (PLC), phospholipase D (PLD), phospholipase A1 (PLA1) and phospholipase A2 (PLA2). PLC hydrolyzes phospholipids at the first phosphodiester bond, producing diacylglycerol (DAG) and a phosphorylated head group. Based on substrate specificity, PLC is divided into two distinctively different groups: phosphoinositide-specific phospholipase C (PI-PLC) and non-specific phospholipase C (NPC). There are six members of the NPC family in Arabidopsis, designated NPC1 through 6 that bears sequence homology to bacterial phosphatidylcholine hydrolyzing PLC (PC-PLC). However, their function remains …

The Impact Of Dynamic And Passive Standing On Bone Mineral Density And Appositional Growth In Immobilized Children, Megan Diane Damcott

Dissertations

The first discovery of the potential role that mechanical loading has on determining the strength of bone occurred in 1892. However, for almost a century after this discovery, the specific mechanisms influenced by mechanical loading remained locked in a mysterious 'black box'. Then in the 1960s, the 'black box' was opened and continued work has now unlocked the basic mechanisms involved in mechanical loading and whole-bone strength. This increased knowledge has spurred clinicians and researchers to investigate the impact of weight-bearing interventions on individuals with an increased risk of osteoporosis. The most common weight-bearing clinical intervention used in non-ambulant populations …

Investigating Nitrate-Dependent Humic Substance Oxidation And In-Service K-12 Teachers' Understanding Of Microbiology, Nastassia N. Jones

Dissertations

Humic substances (HS) are the humified portions of totally decomposed soil organic matter that are ubiquitous in nature. Although these substances have been studied for more than 200 years, neither their metabolic capabilities nor a specific chemical structure has yet to be determined. HS have been studied as a carbon source in many environments where they are degraded; however, previous studies have shown that some microorganisms are capable of utilizing humic substances as electron acceptors and electron donors in anaerobic respiration. Even though there have been humic-reducing and humic-oxidizing microorganisms isolated and studied in recent years, the mechanism of humics …

The Evolution And Development Of Wing Form, Body Size And Flight In Large- And Small-Bodied Fruit Bats (Artibeus Jamaicensis And Carollia Perspiciillata), Jason B. Shaw

Dissertations

Differences in developmental patterns important to diversification are produced through heritable variation of the onset/offset and timing of juvenile growth. As the size and shape of an organism changes during ontogeny, morphological, and behavioral components must adjust to accommodate proper function. This study explored the ontogenetic pathways of two closely related Phyllostomids differing in flight ability, body size, life history strategies, and developmental state at birth. We hypothesized that Artibeus jamaicensis and Carollia perspicillata will show ontogenetic differences that account for the diversification of morphological, body size, and behavioral patterns. Comparisons between the two species‟ flight development, growth rates, and …

The Relations Among Laterality, Cortisol, And Approach-Avoidance Behavior In Garnett's Bushbaby (Otolemur Garnettii), David Burton Hanbury

Dissertations

Many studies to date have demonstrated that approach and avoidance behaviors are processed asymmetrically in the brain and may be reflected in measures such as handedness. The purpose of this study was to extend work in primates on this topic to Garnett’s bushbaby, a prosimian species. Furthermore, to determine whether measures in addition to handedness relate to approach-avoidance behavior, lateralized differences in tympanic membrane temperature were assessed. Cortisol measures were also obtained to determine whether it was related approach-avoidance behavior and handedness. Eleven captive-born Garnett’s bushbabies (Otolemur garnettii) were evaluated for handedness and responsiveness to novelty. Moreover, the …
