Macroconstants Of Development: A New Benchmark For The Strategic Development Of Advanced Countries And Firms, Andrey V. Bystrov, Vyacheslav N. Yusim, Tamilla Curtis

Publications

This research proposed a new indicator of countries’ development called “macroconstants of development”. The literature review indicates that the concept of "macroconstants of development" is not used at the moment in neither the theory nor the practice of industrial policy. Research of longitudinal data of total GDP, GDP per capita and their derivatives for most countries of the world was conducted. An analysis of statistical information has been done by employing econometric analyses.

Based on the analysis of the statistical data, which characterizes the development of large, technologically advanced countries in ordinary conditions, it was identified that the average acceleration …

How Undergraduates' Involvement Affects Sense Of Belonging In Courses That Use Technology, Leroy L. Long Iii

Publications

In order to increase the number of American degree recipients in science, technology, engineering and mathematics (STEM), academics must continually develop ways to improve students’ interest, retention, and success in fields like engineering. Prior researchers have studied the use of educational technology as a way to improve student outcomes and skills. Previous scholars have also investigated students’ perceptions of the usefulness of technology. However, it is unclear if a statistically significant relationship exists between students’ involvement in courses that use technology and their sense of belonging to others on campus. The present study addressed this gap by examining the relationship …

Impact Of Electronic Health Records On Patient Outcomes, Lilian Ndifon, Jude E. Edwards, Leila Halawi

Publications

With the passing of the HITECH Act, EHRs have come into prominence and sharper focus, due to efforts by the government to push for a national adoption of EHRs into our healthcare system. This push for a national adoption of EHRs is based on the premise that it will help improve the quality delivery of health care services and reduce costs. However, this push for a “national adoption” has experienced mixed results. This study was designed to assess the impact of EHRs post-2009, the year of the HITECH Act, to review some of the key contributing factors to this mixed …

Simulation To Application. The Use Of Computer Simulations To Improve Real-World Application Of Learning, Wendi M. Kappers, Stephanie L. Cutler

Publications

Simulations have been used in training and education for years to aid students in gaining the skills needed to complete a task in a low risk environment. However, students can have trouble connecting the skills used in the simulated working environments to skills that are needed to be applied in the real-world environment, referred to as adaptive transfer. The simulations referred to in this study are simulated environments that mirror students kill application, not a simulation of an event that is meant to aid students in the development of concept knowledge around the demonstrated event. This study examines students' ability …

Emerging Tools For Evaluating Safety Management Systems Effectiveness, T. Brady, A. Stolzer

Publications

Safety Management Systems (SMS) have become prevalent in a host of industries, including aviation, for managing safety, but little research has been performed to-date on measuring the effectiveness of SMS. This research examined the independent application of two related concepts to assess effective- ness: IO/SMS, an Input-Output economics concept applied to SMS, and Data Envelopment Analysis (DEA). Input-Output (IO) is a method for systematically determining the inter-relationships among ele- ments in a system. To determine if IO could be applied to SMS, it was necessary to calculate the relative importance to the system of the four components of SMS. Five …

The U.S. Airways Group: A Post-Merger Analysis, Wilfred S. Manuela Jr., Dawna L. Rhoades, Tamilla Curtis

America West Airlines acquired the bankrupt US Airways on September 27, 2005 to form the US Airways Group. Our paper analyzes the post-merger performance of the US Airways Group using airline operating metrics and financial ratios for the period 2005 to 2013. While the airline has still a long way to go to improve its leverage and liquidity ratios, its capital structure and ability to pay its obligations have improved since 2005. Moreover, although the airline is still inefficient in utilizing its assets, the efficiency improvements achieved since the merger have resulted in profits and positive returns to investors. Its …

Students' Perception Of The Flipped Classroom In Graphical Communications, Lulu Sun

Publications

The flipped classroom requires students to study concepts before the class, apply what they learn in the classroom, and work with other students, which then makes it possible to get immediate feedback from the instructor. However, the student’s perception of the flipped classroom is not widely investigated in the area of engineering graphics. This paper presents a study of the flipped classroom in a Graphical Communications course. Students are required to study course material online before the face-to-face classroom experience. The online course study includes multimedia materials and an online quiz that they are required to take. The results of …

Decisions Management During Wildland Fires: Accidents Viewed As A Spatiotemporal Inadequacy, Karim Hardy

Publications

Extreme situations as wildland fires are a source of stress and pressure. In such events, decision-makers and incident commanders need to address a specific problem: how to manage time and resources to make meaningful decisions? Current models of accidents that exist to explain and manage catastrophes and disasters are inadequate and insufficient to deal with resources and time pressure due to uncertainty within a complex organization. Current incident response structures are incompetent and impotent to handle effectively a dynamic evolution of space and time in order to bring a situation back to stability adequately.

Sub-Millisecond Response Time In A Photorefractive Composite Operating Under Cw Conditions, Jong-Sik Moon, Tyler E. Stevens, Todd C. Monson, Dale L. Huber, Sung-Ho Jin, Jin-Woo Oh, Jeffrey G. Winiarz

Chemistry Faculty Research & Creative Works

Extensive study of photorefractive polymeric composites photosensitized with semiconductor nanocrystals has yielded data indicating that the inclusion of such nanocrystals enhances the charge-carrier mobility, and subsequently leads to a reduction in the photorefractive response time. Unfortunately, the included nanocrystals may also act as a source of deep traps, resulting in diminished diffraction efficiencies as well as reduced two beam coupling gain coefficients. Nonetheless, previous studies indicate that this problem is mitigated through the inclusion of semiconductor nanocrystals possessing a relatively narrow band-gap. Here, we fully exploit this property by doping PbS nanocrystals into a newly formulated photorefractive composite based on …

Project Execution: A Research Agenda To Explore The Phenomenon, James Walter Marion, Tracey Richardson, Matthew Earnhardt

Publications

It is observed in the literature that although project management is considered to be an execution-oriented discipline, the Project Management Body of Knowledge developed by the Project Management Institute provides relatively little detail in the Executing process group compared with other process groups such as the Planning and Monitoring and Controlling process groups. It is further observed that project elements considered essential to the success of the project including project Scope, Cost, Schedule, and Risk are not included within the Executing process group. Likewise, the coverage of project execution in the Project Manager Competency Development Framework authored by the Project …

Accident-Precipitating Factors For Crashes In Turbine-Powered General Aviation Aircraft, Douglas Boyd, Alan Stolzer

Publications

General aviation (14CFR Part 91) accounts for 83% of civil aviation fatalities. While much research has focused on accident causes/pilot demographics in this aviation sector, studies to identify factors leading up to the crash (accident-precipitating factors) are few. Such information could inform on pre-emptive remedial action. With this in mind and considering the paucity of research on turbine-powered aircraft accidents the study objectives were to identify accident-precipitating factors and determine if the accident rate has changed over time for such aircraft operating under 14CFR Part 91.

The NTSB Access database was queried for accidents in airplanes (

By investigating critical needs of regulatory compliance and safety, as well as new advancements, it may be possible to identify strategies to address the most pressing concerns of sUAS integration. Findings and recommendations from this research are presented to highlight implications and possible solutions to urgent needs of UAS stakehold-ers, including industry, government, and academia.

Until We Meet Again, Richard Snow, Mary Snow

Publications

As long ago as 1896, Svanti Arrenius conducted a scientific analysis of the relationship between carbon dioxide (CO2) and atmospheric temperatures. Several decades later, GS Callender collected and compiled temperature data from around the world and found there had been an increase in global temperatures. He hypothesized that the rising temperatures were resulting from increasing levels of CO2. These early studies piqued the interest of Gilbert Plass in the mid-20th century who endeavored to determine how CO2 affects temperature. In his effort to determine the possible effects that higher levels of CO2 in the atmosphere were having on the energy …

Crisis Leadership During The Great Recession Of 2008, Steven M. Walker, Matthew P. Earnhardt, Jason M. Newcomer, James W. Marion Jr, Jon C. Tomlinson

Publications

Understanding leadership characteristics, frameworks, components, and contexts that are beneficial to the guidance of organizational policy is useful for understanding the way in which leaders should act during a crisis. Recessions are common throughout economies; yet, many see recessions as crises. Due to the chaotic nature of economic recessions, leaders must work in conditions of uncertainty, complexity, and volatility. Therefore, using a qualitative phenomenological approach, an examination was conducted on leaders’ lived experiences of the Great Recession of 2008 to further understand the concept of crisis leadership. A discussion is included on the way in which leaders internalize and analyze …

What Are The Predictors Of System-Wide Trust Loss In Transportation Automation?, Stephen Rice, Scott R. Winter, John E. Deaton, Ismael Cremer

Publications

Prior research has examined how individuals place trust in single (e.g., Meyer, 2001, 2004) and multiple (e.g., Geels-Blair, Rice, & Schwark, 2013) automated devices when one fails. This has shown that participants are influenced by system-wide trust (SWT). What has been missing is an investigation into what types of people succumb to SWT effects. The current study attempts to replicate SWT findings and identify possible predictors of individuals likely to be influenced by SWT. The findings did demonstrate a replication of SWT. The study found that ‘‘feelings of negativity when automated devices fail’’ was a significant predictor of SWT theory.

Intermittency Of Gravity Wave Momentum Flux In The Mesopause Region Observed With An All-Sky Airglow Imager, Bing Cao, Alan Z. Liu

Publications

The intermittency of gravity wave momentum flux (MF) near the OH airglow layer (∼87 km) in the mesopause region is investigated for the first time using observation of all-sky airglow imager over Maui, Hawaii (20.7∘N, 156.3∘W), and Cerro Pachón, Chile (30.3∘S, 70.7∘W). At both sites, the probability density function (pdf) of gravity wave MF shows two distinct distributions depending on the magnitude of the MF. For MF smaller (larger) than ∼16 m2 s−2 (0.091 mPa), the pdf follows a lognormal (power law) distribution. The intermittency represented by the Bernoulli proxy and the percentile ratio shows that gravity waves have higher …

Chemical Transport Of Neutral Atmospheric Constituents By Waves And Turbulence: Theory And Observations, Chester S. Gardner, Alan Liu

Publications

Vertical chemical transport occurs when the density fluctuations of a species, caused by perturbations of its chemistry, are strongly correlated with the vertical wind fluctuations. Chemical transport can exceed dynamical and eddy transport of chemically active species. Theoretical expressions are derived for the chemical fluxes and transport velocities and used to characterize the vertical transport of mesospheric O3 and meteoric Na and Fe between 85 and 100 km. Chemical transport is dependent on the intrinsic frequency spectrum of the temperature fluctuations and on the chemical cutoff periods of the species. For O3 only high-frequency fluctuations contribute to chemical transport because …

Southern Hemisphere Summer Mesopause Responses To El Niño–Southern Oscillation, Tao Li, Natalia Calvo, Jia Yue, James Russell Iii, Alan Liu

Publications

In the Southern Hemisphere (SH) polar region, satellite observations reveal a significant uppermesosphere cooling and a lower-thermosphere warming during warm ENSO events in December. An opposite pattern is observed in the tropical mesopause region. The observed upper-mesosphere cooling agrees with a climate model simulation. Analysis of the simulation suggests that enhanced planetary wave (PW) dissipation in the Northern Hemisphere (NH) high-latitude stratosphere during El Niño strengthens the Brewer–Dobson circulation and cools the equatorial stratosphere. This increases the magnitude of the SH stratosphere meridional temperature gradient and thus causes the anomalous stratospheric easterly zonal wind and early breakdown of the SH …

Evidence Of The Excitation Of A Ring-Like Gravity Wave In The Mesosphere Over The Andes Lidar Observatory, Fabio Vargas, Gary Swenson,, Alan Liu, Dominique Pautet

Publications

On 23 March 2012, our all-sky imager recorded a concentric, ring-like gravity wave pattern. The wave arose within the area covered by images of both OH and O(1S) nightglow emissions taken at the Andes Lidar Observatory (ALO), Chile (30.3°S, 70.7°W). We have estimated the observed and intrinsic parameters of the event and located the wave source within the lower mesosphere altitude range using a reverse ray tracing method. By the analysis of GOES and LIS satellite images, we have not found evidence of neither convective nor lightning activity nearby ALO, indicating that the source of the ring-like wave …

Audio Tours Of Fish: Angling For An Effective Mediated Speech, Sally Blomstrom, Barbara Hayford, Lori A. Mumpower

Publications

Public speaking is a course required in many degree programs traditionally taught in a face to face setting. Online and hybrid courses are now offered by many institutions in addition to traditional courses, and they are more likely to include mediated speech assignments. Mediated speaking situations include webinars, videoconferences, video recordings of speeches on DVD or YouTube, and other options that students may well find themselves using in their personal and professional communication. Online and some hybrid courses assign mediated speaking situations for the submission of speeches, not as a genre unto itself. In traditional face to face public speaking …

Plasma Density Analysis Of Cubesat Wakes In The Earth’S Ionosphere, Robert M. Albarran Ii, Aroh Barjatya

Publications

Spinning or tumbling CubeSats with Langmuir probes deployed on booms will render spin-modulated plasma densities as the probes move in and out of the spacecraft wake. It is traditionally assumed that the lower-density measurements from the spin cycle are made in the spacecraft wake, and the higher-density measurements are outside the wake. Although this assumption is valid for larger spacecraft in the Earth’s ionosphere, this paper scrutinizes its validity for CubeSats in similar conditions. Spacecraft–plasma interactions (surface charging, plasma sheaths, and wakes) are less understood for CubeSats, and the small CubeSat dimensions must be considered with respect to characteristic length …

Micro Cavitation Bubbles On The Movement Of An Experimental Submarine: Theory And Experiments, S.C. Mancas, Shahrdad G. Sajjadi, Asalie Anderson, Derek Hoffman

Publications

To understand the nature of movement of submarine, micro cavitation bubbles were systematically diffused around the exterior of a test body (tube) fully submerged in a water tank. The primary purpose was to assess the feasibility of applying micro cavitation as a means of depth control for underwater vehicles, mainly but not limited to submarines. Ideally, the results would indicate the use of micro cavitation as a more efficient alternative to underwater vehicle depth control than the conventional ballast tank method. The current approach utilizes the Archimedes' principle of buoyancy to alter the density of the object affected, making it …

Teaching Innovation And Creativity: Turning Theory Into Practice, Aaron M. Glassman, Rose Opengart

Publications

Innovation and creativity are the lifeblood of organizations. As such, businesses expect college graduates to exhibit the skills necessary to engage in these behaviors. This research explores the concept of innovation, whether it is innate, or if the skill can be taught within the university setting, and how universities are addressing the need for, and teaching innovation. A search of the word “innovation” within educational courses found that most courses are theoretically-oriented or are efforts to cultivate entrepreneurs and/or new inventions, though some appear more practical in nature. A sampling of 50 ACBSP and AACSB accredited universities offering courses in …
