Bottom-up and top-down forces in tidepools : the influence of nutrients, herbivores, and wave exposure on community structure

Creator:: Nielsen, Karina Johanna
Abstract:: The relationship between nutrients and community structure is poorly understood in open-coast habitats. I created a system of artificial tidepools, of identical age and physical dimensions, at two sites that differed in wave exposure, and manipulated nutrient levels and the abundance of herbivores. Using these unique field mesocosms, I explored...

Neutron scattering studies of magnetic semiconducting superlattices

Creator:: Goldman, Keith Isaac
Abstract:: Neutron diffraction experiments on europium telluride/lead telluride super-lattice systems reveal pronounced correlations between the antiferromagnetic EuTe layers. The results from an assortment of varying experimental conditions (applied magnetic field, temperature, etc.) and their relevance to the physical mechanism underlying this striking phenomena are discussed. Stochastic computer simulations are compared to...

Expanding the scope of a Diels-Alder approach to biaryl synthesis

Creator:: Schwartz, Johanna Perkins
Abstract:: A Diels-Alder approach to biaryls (DAB) has been applied towards the synthesis of highly substituted, programmable biaryl templates. Tri- and tetra-ortho-substituted biaryls can be produced in just three to four steps from commercially available materials utilizing the Diels-Alder [4+2] cycloaddition. The methods described herein will illustrate the ability of mono...

Characterization of the transition to the progamic phase in Zea mays pollen

Creator:: Smyth, Johanna C.
Abstract:: The transition of mature pollen to the progamic phase represents an important step in the regulation of plant sexual reproduction. The progamic phase encompasses the initiation of pollen tube germination, growth of the pollen tube through the stigma (the silk in maize) and concludes with fertilization of the female gametophyte....

An historical review of Kolb's formulation of experiential learning theory

Creator:: Hickcox, Leslie K. (Leslie Kay), 1951-
Abstract:: The central purposes of this study were to review the historical sources of David Kolb's formulation of experiential learning theory, and to determine the effect and application of Kolb's theory and Learning Style Inventory as reflected in the literature between 1971 and 1990. It was found that Kolb based his...

Pre-service grief and loss preparation in CACREP accredited school counseling programs

Creator:: Low, Lori L.
Abstract:: Youth today experience high degrees of loss and change, resulting in grief (Goldman, 2001). Little evidence exists of school counselors' academic preparation in grief counseling. The purpose of this research study was to determine how CACREP school counseling programs prepare school counselors in the areas of grief and loss, including...

Quasi-Experimental Methods to Assess Impacts of Energy Policy on Pregnancy Outcomes

Creator:: Willis, Mary D.
Abstract:: Most energy policies that are implemented in the United States dictate how energy is produced, distributed, and consumed, but policies generally neglect to fully investigate how these decisions impact population health. Individuals who live near energy sector components are often different to those that reside further away and change over...

The impact of selected experiences on women during mid-life transition : a retrospective study

Creator:: Lacy, Patricia A.
Abstract:: The purpose of this study was to examine the mid-life period of women's lives. It attempted to determine if this time is generally one of crisis, or more commonly a period of smooth transition. Furthermore, it attempted to determine if there is a typical pattern of emotional concerns experienced by...

Improving Soft Snake Robot Locomotion Through Targeted Environmental Interactions Using Artificial Snake Skin

Creator:: Branyan, Callie A.
Abstract:: This dissertation outlines the design and development of the first fully-soft, snake robot and its snake-inspired skin. Soft robotics takes advantage of soft materials to, among other things, improve robot interactions with complex, unstructured environments. Due to the interplay between the soft material and the environment, minor tweaks to the...
