The Institutional-Professoriate Tension: Scholarship Identity And Academic Alignment That Impact Scholars' Productivity And Well-Being, Milagros Pereyra-Rojas
The Institutional-Professoriate Tension: Scholarship Identity And Academic Alignment That Impact Scholars' Productivity And Well-Being, Milagros Pereyra-Rojas
Student Scholarship
Scholars and institutions alike are concerned with academic productivity. Scholars not only further knowledge in their professional fields, they also bring visibility and prestige to themselves and their institutions, which in turn attracts research grants and more qualified faculty and graduate students. Many studies have been done on scholar productivity; however, most of them focus on individual factors such as gender, marital status, and psychological characteristics rather than intrinsic academic factors such as scholars' academic values, institutional expectations and academic alignment between the scholar and the institution. In this study, we developed measures for the different kinds of scholarship based …

Chemistry Faculty Research and Publications
N-(9-Oxothioxanthenyl)benzothiophene carboxamides bearing leaving groups (LG− = Cl−, PhS−, HS−, PhCH2S−) at the C-3 position of the benzothiophene ring system photochemically cyclize with nearly quantitative release of the leaving group, LG−. The LG− photoexpulsions can be conducted with 390 nm light or with a sunlamp. Solubility in 75% aqueous CH3CN is achieved by introducing a carboxylate group at the C-6 position of the benzothiophene ring. The carboxylate and methyl ester derivatives regiospecifically cyclize at the more hindered C-1 position of the thioxanthone ring. …
Global Permutationally Invariant Potential Energy Surface For Ozone Forming Reaction, Mehdi Ayouz, Dmitri Babikov
Global Permutationally Invariant Potential Energy Surface For Ozone Forming Reaction, Mehdi Ayouz, Dmitri Babikov
Chemistry Faculty Research and Publications
We constructed new global potential energy surface for O + O2 → O3 reaction. It is based on high level electronic structure theory calculations and employs fitting by permutationally invariant polynomial functions. This method of surface construction takes full advantage of permutation symmetry of three O nuclei and allows reducing dramatically the number of ab initio data points needed for accurate surface representation. New potential energy surface offers dramatic improvement over older surface of ozone in terms of dissociation energy and behavior along the minimum energy path. It can be used to refine the existing theories of ozone …

Robust Multivariate Regression, Hasthika S. Rupasinghe Arachchige Don
Robust Multivariate Regression, Hasthika S. Rupasinghe Arachchige Don
Research Papers
A robust multivariate linear regression estimator can be obtained by replacing the least squares estimator with the robust hbreg estimator. Then the robust multivariate linear regression estimator is asymptotically equivalent to the classical multivariate linear regression estimator since the probability that the robust estimator is equal to the classical estimator goes to one in probability as the sample size n tends to infinity for a large class of iid zero mean error distributions. This paper discusses the robust estimator and some tests using the robust estimator that are asymptotically equivalent to those using the classical estimator.

A Tunable Electromagnetic Band-Gap Microstrip Filter, Greg A. Lancaster
A Tunable Electromagnetic Band-Gap Microstrip Filter, Greg A. Lancaster
Master's Theses
In high frequency design, harmonic suppression is a persistent struggle. Non-linear devices such as switches and amplifiers produce unwanted harmonics which may interfere with other frequency bands. Filtering is a widely accepted solution, however there are various shortcomings involved. Suppressing multiple harmonics, if desired, with traditional lumped element and distributed component band-stop filters requires using multiple filters. These topologies are not easily made tunable either. A new filter topology is investigated called Electromagnetic Band-Gap (EBG) structures.
EBG structures have recently gained the interest of microwave designers due to their periodic nature which prohibits the propagation of certain frequency bands. EBG …
Long Term Economic Impact Of The Natural Resources And Human Capital On The Growth Rate, Ibrahima Coulibaly
Long Term Economic Impact Of The Natural Resources And Human Capital On The Growth Rate, Ibrahima Coulibaly
Research Papers
They have been growing debate among economists and others social-scientists about the relationship between natural resources and human capital and growth. Although most economists agreed, in short run that natural resources do impact growth negatively through human capital. But, the long term relationship seems to be unsettled, and they have not been too many studies focus on the long term equilibrium between natural resources and human capital. Therefore, this paper aims to contribute in growth literature, by studying at the long term relationship between natural resources, human capital, and growth, using Mali as a case study. Natural resource seems to …

We present data from nighttime sounding rocket flights in the low latitude E region. The payloads carried a sweeping Langmuir probe, a plasma impedance probe, and electric field probes. A detailed examination of the plasma density, temperature, and electric field measurements show two strong sporadic E (Es) layers with very high electron temperatures (∼1000 K) on each side of the upper layer. The lower layer was consistent with the presence of a strong zonal neutral wind shear. The upper layer was strongly influenced by the presence of a strongly negative vertical electric field, with zonal winds and …
Hydrodynamic Modeling Of Ns-Laser Ablation, David Autrique, Vasilios Alexiades, Harihar Khanal
Hydrodynamic Modeling Of Ns-Laser Ablation, David Autrique, Vasilios Alexiades, Harihar Khanal
Publications
Laser ablation is a versatile and widespread technique, applied in an increasing number of medical, industrial and analytical applications. A hydrodynamic multiphase model describing nanosecond-laser ablation (ns- LA) is outlined. The model accounts for target heating and mass removal mechanisms as well as plume expansion and plasma formation. A copper target is placed in an ambient environment consisting of helium and irradiated by a nanosecond-laser pulse. The effect of variable laser settings on the ablation process is explored in 1-D numerical simulations.

Heteroclinic And Homoclinic Connections Between The Sun-Earth Triangular Points And Quasi-Satellite Orbits For Solar Observations, Pedro J. Llanos, Gerald R. Hintz, Martin W. Lo, James K. Miller
Publications
Investigation of new orbit geometries exhibits a very attractive behavior for a spacecraft to monitor space weather coming from the Sun. Several orbit transfer mechanisms are analyzed as potential alternatives to monitor solar activity such as a sub-solar orbit or quasi-satellite orbit and short and long heteroclinic and homoclinic connections between the triangular points L4 and L5 and the collinear point L3 of the CRTBP (circular restricted three-body problem) in the Sun-Earth system. These trajectories could serve as channels through where material can be transported from L5 to L3 by performing small maneuvers at the departure of the Trojan orbit. …

The Impact Of The Clinical Nurse Leader/Navigator On Clinical Outcomes And Patient Satisfaction, Diane Smith Raines
UNF Graduate Theses and Dissertations
In an era of value based purchasing and healthcare reform, hospitals face the challenge of delivering high quality care in an environment of diminishing resources. This performance improvement project describes the use of master’s prepared nurses on medical surgical units to improve quality and patient satisfaction. The setting was five medical surgical units in a 200+ bed hospital in the southeastern United States. Declining resources necessitated an increase in the nurse to patient ratios on the units (from 5:1 to 6:1). The project involved the modification of the model of care through the change in nurse/patient ratios and the addition …

Sediment Impact On The Formation Of Hypoxic Waters In The Northern Gulf Of Mexico: A Synthesis Of Sediment Texture, Composition, Erodibility And Transport, Rangley Claude Mickey
Electronic Theses and Dissertations
Annual hypoxic events have been found to occur over the past several decades in the northern Gulf of Mexico (nGOM) and have prompted researchers to begin studying the mechanisms that control hypoxia formation so they may advise policy makers on the appropriate mitigating responses. This has led to the development of 3-dimensional modeling systems that incorporate marine physical, biological, geological, and chemical processes that may impact the formation and duration of hypoxic regimes in the nGOM. This study used field, laboratory, and modeling techniques to examine how sediment may be eroded from the seabed and where/how it is transported across …
