Student Performance In Virtual Schooling: Looking Beyond The Numbers, Michael Barbour, Dennis Mulcahy

Education Faculty Publications

Seven years ago the Centre for Distance Learning and Innovation began a virtual high school within the Canadian province of Newfoundland and Labrador. Designed primarily to provide courses in specialized areas to students in rural areas, where schools have difficulty in attracting these teachers, there is concern that the opportunities provided by this virtual school are “second rate.” The purpose of the study is to examine the student achievement in standardized public exams and final course scores in the province between different delivery models, geographic location and subject area to determine whether or not students are succeeding in the virtual …

The Effect Of Leadership Skill-Building On Nurse Leader Behaviors, Barbara Drummond-Huth

UNF Graduate Theses and Dissertations

Patient outcome data are an important factor in healthcare. Reports by the Institute of Medicine between 1999 and 2001, as well as recent research by Linda Aiken and her colleagues have added more emphasis to measures that can be taken to improve patient outcomes. Because of the role they play in healthcare facilities, nurse leaders are in a position to take the lead in improving patient outcomes. There is evidence to suggest that nurse leaders' transformational leadership behaviors are associated with positive patient outcomes.

The purpose of this project was to identify the effect of transformational leadership skill-building training on …

Estimating Deer Abundance In Suburban Areas With Infrared-Triggered Cameras, Paul D. Curtis, Bazartseren Boldgiv, Peter M. Mattison, Jason R. Boulanger

Biology Faculty Publications

Interactions between humans and white-tailed deer (Odocoileus virginianus) have become common, often resulting in management actions to mitigate negative impacts. Changes in population size are generally used to judge management actions. We examined deer population estimation techniques during 2 mark-resighting experiments in a woodland-grassland habitat in central New York State and in a suburban area. We compared program NOREMARK, Lincoln-Peterson estimates, and Jacobson’s (1997) buck:doe ratios (BDR) for estimating deer abundance. In the first field trial, we sought to validate the camera survey methods and computer applications. We used infrared-triggered cameras (IRCs) to survey a white-tailed deer population …

The Outsourcing Of National Defense, Christopher Weimar

Dissertations, Theses, and Capstone Projects

The outsourcing of military activities and services has grown dramatically in recent decades. My objective is to understand and explain this phenomenon at work in the United States Department of Defense (DoD) using theoretical frameworks of strategic efficiency, political ideology and organizational theory factors. This study seeks to answer the question, why has the DOD outsourced support activities and functions that contribute to larger national security objectives and were traditionally performed by DoD personnel? I'll use a case-study methodology to examine outsourcing in the DoD between 1970 and 2005, to include an in-depth look at the information technology (IT) networks …

I Knew You When, Jami Dittus

Theses and Dissertations

Four short stories and the first quarter of a novel revolve around characters sick with want, sick of and from the worlds in which they live. They crave connection with other people, often through indirect methods, but can’t always manage the connections they make with other characters. Objects, comforting and static when people cannot be, take prominence as connection to the real world.

Modelling Situation Awareness For Context‐Aware Decision Support, Yu-Hong Feng, Teck-Hou Teng, Ah-Hwee Tan

Research Collection School Of Computing and Information Systems

Situation awareness modelling is popularly used in the command and control domain for situation assessment and decision support. However, situation models in real-world applications are typically complex and not easy to use. This paper presents a Context-aware Decision Support (CaDS) system, which consists of a situation model for shared situation awareness modelling and a group of entity agents, one for each individual user, for focused and customized decision support. By incorporating a rule-based inference engine, the entity agents provide functions including event classification, action recommendation, and proactive decision making. The implementation and the performance of the proposed system are demonstrated …

When Is It Beneficial For A Firm To Pursue A Unified Procurement Strategy For Enterprise Software Solutions?, Robert J. Kauffman, Juliana Y. Tsai

Research Collection School Of Computing and Information Systems

The underlying structure of the enterprise software marketplace during the past ten years suggests that the arrangements that firms make with respect to the acquisition of such software capabilities will become increasingly concentrated. This article explores the multiple theoretical rationales and business cases for the move to a unified procurement strategy for enterprise software, reflecting some differences in terms of what might be expected from the predictions of the well known move-to-the-middle hypothesis. Our central argument is that a "move-to-the-middle" with more than just a single vendor is the likely outcome in unconsolidated industry markets. In industries experiencing consolidation, firms …

Doctrine And Fairness In The Law Of Contract, Andrew B.L. Phang

Research Collection Yong Pung How School Of Law

This paper explores, through illustrations from the law of contract, the important centraltheme to the effect that the rules and principles, which constitute thedoctrineof the law,are not ends in themselves but are, rather, the means through which the courts arrive atsubstantively fairoutcomes in the cases before them. The paper focuses on the concept of‘radicalism’, which relates to the point at which the courts decide that it is legallypermissible to hold that a contract should come to an end because a radical or funda-mental ‘legal tipping point’ has not only been arrived at but has, in fact, been crossed. Itexplores the …

Structural Study On Ammonia Borane For Hydrogen Storage, William Joseph James, L. Jagat, Q. Cai, William B. Yelon, J. B. Yang

Chemistry Faculty Research & Creative Works

Ammonia borane (BH3NH3) is a promising hydrogen storage material because of its high gravimetric (19.6 wt.% H2) and volumetric hydrogen density with an accompanying moderate decomposition temperature. Previously reported structures determined by using x-ray and neutron diffraction on hydrides show differences in bond lengths and atomic coordination. Here, the crystal structures of fully and half deuterated ammonia borane were investigated as a function of temperature using powder neutron diffraction. the neutron diffraction patterns show a significant difference due to large difference in the scattering length of D and H. It is evident that an order-disorder phase transition occurs around 225 …

A Semiotic Analysis Of Unified Modeling Language Graphical Notations, Keng Siau, Yuhong Tian

Research Collection School Of Computing and Information Systems

Unified modeling language (UML) is the standard modeling language for object-oriented system development. Despite its status as a standard, UML has a fuzzy formal specification and a weak theoretical foundation. Semiotics, the study of signs, provides a good theoretical foundation for UML research because graphical notations (or visual signs) of UML are subjected to the principles of signs. In our research, we use semiotics to study the effectiveness of graphical notations in UML. We hypothesized that the use of iconic signs as UML graphical notations leads to representation that is more accurately interpreted and that arouses fewer connotations than the …

A Study Of The Beneficial Role Of Thiol Antioxidant Supplementation In Various Forms Of Glutathione Deficiency, Linu Sara Abraham

Doctoral Dissertations

"Oxidative stress plays a major role in the pathology of numerous disorders afflicting humans, ranging from neurodegenerative diseases, to cancer, and heavy metal toxicity. Scientists are on the constant lookout for new and better antioxidants that have the ability to slow, if not stop the harmful degenerative effects of free radicals in oxidative stress related disorders. Both synthetic and naturally occurring compounds are being constantly screened for their antioxidant properties. This study attempted to evaluate the abilities of a thiol antioxidant, N-Acetylcysteine amide (NACA), to protect cells from the harmful effects of glutathione depletion in two different models of oxidative …

Detecting Dissimilarities In Em Constitutive Parameters Using Differential Imaging Operator On Reconstructed Wavefield, Md. Ishfaqur Raza, Richard E. Dubroff

Electrical and Computer Engineering Faculty Research & Creative Works

Electromagnetic field will scatter when incident on boundaries separating media with different constitutive parameters. This paper demonstrates the use of a differential operator on recorded scattered waves to reveal the shape of the boundary. The method is noninvasive and is composed of three phases. First, the area of interest is illuminated and the resulting scattered electromagnetic fields are recorded. In the 2nd phase, the captured data is numerically reverse simulated in time to reconstruct the field distribution in the region of interest. Finally, the differential imaging operator is applied on the reconstructed wave field, creating an image delineating the boundary …

An Improved Upfc Control For Oscillation Damping, Jagannathan Sarangapani, Mariesa Crow, Jianjun Guo

Electrical and Computer Engineering Faculty Research & Creative Works

This paper proposes a new control approach for a unified power flow controller (UPFC) for power system oscillation damping. This control is simple to implement, yet is valid over a wide range of operating conditions. It is also effective in the presence of multiple modes of oscillation. The proposed control is implemented in several test systems and is compared against a traditional PI control.

The Design By Molecular Dynamics Modeling And Simulations Of Porous Polymer Adsorbent Media Immobilized On The Throughpore Surfaces Of Polymeric Monoliths, E. Riccardi, J. C. Wang, A. I. Liapis

Chemical and Biochemical Engineering Faculty Research & Creative Works

Ion-exchange porous adsorbent media having intermediate and low surface densities of dextran polymer grafted on the surface of the through pores of polymeric monoliths are constructed and characterized by a molecular dynamic modeling and simulation approach that has also been shown to be effective in the construction and characterization of porous ion-exchange adsorbent media whose number of immobilized dextran polymer chains per unit surface area is high. the activation step that prepares the surface of the pores of the dextran polymer layer for the immobilization of the charged ligands insignificantly affected the pore structure of the dextran polymer layer, while …

Preliminary Investigation Of Novel Bone Graft Substitutes Based On Strontium-Calcium-Zinc-Silicate Glasses, D. Boyd, G. Carroll, Mark R. Towler, C. Freeman, P. Farthing, I. M. Brook

Chemical and Biochemical Engineering Faculty Research & Creative Works

Bone graft procedures typically require surgeons to harvest bone from a second site on a given patient (Autograft) before repairing a bone defect. However, this results in increased surgical time, excessive blood loss and a significant increase in pain. In this context a synthetic bone graft with excellent histocompatibility, built in antibacterial efficacy and the ability to regenerate healthy tissue in place of diseased tissue would be a significant step forward relative to current state of the art philosophies. We developed a range of calcium-strontium-zinc-silicate glass-based bone grafts and characterized their structure and physical properties, then evaluated their in vitro …

Phonon Confinement Effects In The Raman Spectrum Of Nanodiamond, Sebastian Osswald, Vadym Mochalin, Mickaël Havel, Gleb N. Yushin, Yury G. Gogotsi

Chemistry Faculty Research & Creative Works

Nanodiamonds (ND) exhibit unique properties due to their small size and high surface-to-volume ratio compared to bulk diamonds. A reduction in crystal size also affects ND Raman spectra. The confinement of optical phonons in nanocrystals (<10 nm) results in asymmetrically broadened Raman lines, which are shifted toward lower wavenumbers. The phonon confinement model (PCM) relates the observed changes in the Raman spectra to the crystal size and can be used for size characterization at the nanoscale. While the PCM was successfully applied to a variety of materials including Si and BN, results remained unsatisfactory in the case of ND. In order to improve the agreement between the predictions of the model and experimental Raman spectra of ND, effects such as crystal size distribution, lattice defects, and the energy dispersion of the phonon modes were taken into consideration and incorporated into the PCM. This work has shown that phonon wave vectors from small vibrational domains lead to a broad shoulder peak at ~1250 cm^-1, that is often observed in the Raman spectrum of ND.

Earth's Heat Source -- The Sun, Oliver Manuel

Chemistry Faculty Research & Creative Works

The Sun encompasses planet Earth, supplies the heat that warms it, and even shakes it. The United Nation's Intergovernmental Panel on Climate Change (IPCC) assumed that solar influence on Earth's climate is limited to changes in solar irradiance and adopted the consensus opinion of a hydrogen-filled Sun - the Standard Solar Model (SSM). They did not consider the alternative solar model and instead adopted another consensus opinion: Anthropogenic greenhouse gases play a dominant role in climate change. The SSM fails to explain the solar wind, solar cycles, and the empirical link of solar surface activity with Earth's changing climate. The …

Ac Susceptibility And Heat Capacity Studies Of The Geometrically Frustrated Pyrochlores Terbium Titanium Tin Oxides And Holmium Titanates, Daniel Antonio

UNLV Theses, Dissertations, Professional Papers, and Capstones

Materials with a geometrically frustrated magnetic pyrochlore lattice have been of interest due to their unusual ground states. Tb 2 Ti 2 O 7 is known for having a spin liquid ground state which does not transition to a long-range ordered state down to at least 50 mK. Ho 2 Ti 2 O 7 has a macroscopically degenerate spin ice ground state which resembles that of the proton ordering in water ice. Heat Capacity measurements of Tb 2 Ti 2- x Sn x O 7 were done down to 0.36 K and AC magnetic susceptibility measurements of Ho 2- x …

Desert Varnish As An Indicator Of Modern-Day Air Pollution In Southern Nevada, Piotr Nowinski

UNLV Theses, Dissertations, Professional Papers, and Capstones

Rock varnish, often called desert varnish, is a slow-growing, manganese-rich coating that accumulates on exposed rock surfaces. The mechanism of varnish formation is not fully understood, however, most authors agree that varnishes derive their components from the atmosphere. The main goal of this study was to demonstrate the potential use of desert varnish as a passive environmental monitor of present and past atmospheric pollution. Analysis of varnishes is a new field that can potentially provide records of pre-anthropogenic levels of atmospheric metals and other environmental pollutants. To evaluate the potential of desert varnish as an environmental monitoring tool, the following …

Effects Of Marital Quality On Children In Brazilian Families, Stephen V. Stutzman, Richard B. Miller, Cody S. Hollist, Olga G. Falceto

Department of Child, Youth, and Family Studies: Faculty Publications

Although there is a robust literature supporting the empirical generalization that parental conflict is related to childhood problems, the research has primarily studied European American populations in the U.S. There is minimal research that investigates the relationship between marital distress and child outcomes in other cultures (Bradford et al., 2004; Buehler et al., 1997; Krishnakumar & Buehler, 2000; Shek, 2001), including a specific lack of knowledge regarding Latino populations. This is a significant gap in the literature since Latino children make up the largest minority group in the U.S., accounting for 16% of children younger than 18 years of age …

This handbook helps take some of the mystery out of practicing in tribal courts. Without the necessary information to learn new rules and protocols many attorneys are understandably reluctant to practice in a new jurisdiction. As a result, tribal courts are underused or misused. This handbook is intended to help attorneys and advocates become more aware of the various individual tribal court systems and to learn their rules and protocol.

Cognitive Transfer Of A Reading Strategy From Oral Participation To Silent Reading, Myrtle Welch

Journal of Inquiry and Action in Education

This article explains a viable, researched, teaching activity that I call Treasure Hunt. Treasure Hunt is an oral participation, vocabulary lesson that facilitates the transfer of reading comprehension to silent reading. I designed and used this activity with adolescent, challenged readers. The readers had scored below the 70th percentile on a state exam. This activity became a research project for the purpose of testing its reliability. Students actually thought of the activity as a vocabulary game; however, their ability to comprehend texts was enhanced after they participated. Comprehension was fostered through locating words in texts, reading orally, listening to themselves …

Intellectual Ability In Children With Anxiety: A Replication And Exploration Of The Differences, Melissa S. Munson

LSU Master's Theses

The purpose of this study was to examine the effect of anxiety on the intellectual functioning of children. Specifically, the current researchers sought to replicate previous findings that children with higher levels of anxiety have significantly lower scores on tests of intelligence. A second goal was to examine possible reasons for these deficits, including possible deficits in working memory and/or attention. Participants were divided into two groups with high and low anxiety, based on a self-report measure, though none of the children reported clinically problematic anxiety. The participants were 19 children (10 males, 9 females) who were recruited from the …
