Commentary On Healthcare And Disruptive Innovation, Hilary Finch, Affia Abasi-Amefon, Woosub Jung, Lucas Potter, Xavier-Lewis Palmer Jan 2023

Commentary On Healthcare And Disruptive Innovation, Hilary Finch, Affia Abasi-Amefon, Woosub Jung, Lucas Potter, Xavier-Lewis Palmer

Electrical & Computer Engineering Faculty Publications

Exploits of technology have been an issue in healthcare for many years. Many hospital systems have a problem with “disruptive innovation” when introducing new technology. Disruptive innovation is “an innovation that creates a new market by applying a different set of values, which ultimately overtakes an existing market” (Sensmeier, 2012). Modern healthcare systems are historically slow to accept new technological advancements. This may be because patient-based, provider-based, or industry-wide decisions are tough to implement, giving way to dire consequences. One potential consequence is that healthcare providers may not be able to provide the best possible care to patients. For example, …


Thither The Russian Navy? Putin’S Navalization In A Historical Context, William Emerson Bunn Dec 2022

Thither The Russian Navy? Putin’S Navalization In A Historical Context, William Emerson Bunn

Graduate Program in International Studies Theses & Dissertations

The Syrian operation of 2012 was the first successful employment by Russia of expeditionary warfare, narrowly defined as naval support to Russian (or Soviet) ground forces in a war away from their periphery (i.e., in a country that does not border them), from the sea. This was brought about in part by the development of two types of cruise missiles: advanced anti-ship missiles (which protects their expeditionary force from NATO naval units, enabling local sea control) and new land attack cruise missiles (similar in design and capability to the U.S. Tomahawk). In the past geographical, technological and political constraints …


Chapter 07. Message Design For Healthcare Simulation, Maria Satre Oct 2022

Chapter 07. Message Design For Healthcare Simulation, Maria Satre

Instructional Message Design, Volume 2

Simulation is a teaching method that motivates and engages learners (Ifenthaler et al. 2020; Martin & Betrus, 2019), can provide better student performance outcomes compared to traditional classroom education (Chernikova et al. 2020; D’Angleo et al., 2014; Di Natale et al., 2020; Gralnick & Levy, 2011; Pellas et al., 2019), and can even replace some real-world learning experiences (Alexander et al., 2015). Instructional designers who develop healthcare simulations should use relevant learning theory and instructional message design to ensure that the simulation is learner-centered and based in evidence-based practice to maximize the potential for the learning experience.


Securing Russia: Seeking Ontological Security In The Arctic, Brian W. Cole Oct 2022

Securing Russia: Seeking Ontological Security In The Arctic, Brian W. Cole

Graduate Program in International Studies Theses & Dissertations

Following the collapse of the Soviet Union, Russia experienced an abrupt discontinuity in its sense of identity. This break in identity, and a more profound lost sense of self, creates a strong need to reestablish continuity. The need to regain that sense of self is strong and can supersede other concerns. Ontological security theory proposes that the need to maintain identity can outweigh physical security considerations. This study uses game theory methodology and the Arctic as a contextual example to demonstrate that ontological security-seeking actors are willing to sacrifice physical security. Today, the current conditions in the Arctic reflect a …

Present At The Creation, A Redux: The Need For Strategic Minded Joint Force Officers In A Rapidly Changing And Dynamic International Security Environment, Thomas Joseph Snukis

Graduate Program in International Studies Theses & Dissertations

The US Joint Force has an outstanding record over its history of superb performance at the tactical level of war. Inarguably, the United States is currently the best tactical Joint Force in the world a product of a world class tactical education, training, and development program generating and sustaining that tactical proficiency at the individual and organizational level. While tactical education and training programs have been extremely successful, the Professional Military Education (PME) responsible for developing strategic mastery has not been as highly rated. Over the past seventy-five years numerous indictments have been levied against the US PME enterprise, and …


The Carrot Vs. The Stick: A Comparative Analysis Of Secondary Sanctions Vs. Positive Inducements In Gaining European Support For A U.S.-Led Sanction Regime, Andy Gomez May 2022

The Carrot Vs. The Stick: A Comparative Analysis Of Secondary Sanctions Vs. Positive Inducements In Gaining European Support For A U.S.-Led Sanction Regime, Andy Gomez

Graduate Program in International Studies Theses & Dissertations

The United States has a history of imposing its will on other countries via aggressive sanction regimes. In many of those regimes, U.S. policymakers note that support from European partner states is paramount to the regime's success. Over the past 20 years, the U.S. and its European partner state's interests have had relatively aligned, fostering cooperation and implementation of like-minded policies against target states. The end of paralleled interests left policymakers with a conundrum, which stemmed the research question of this study. What circumstances determine whether secondary sanctions or positive inducements are more effective in gaining European support for a …


Russia, Europe And Central Asia Energy Security And Pipeline Politics, Mehmet Kınacı May 2022

Russia, Europe And Central Asia Energy Security And Pipeline Politics, Mehmet Kınacı

Graduate Program in International Studies Theses & Dissertations

Energy Security will continue to remain as one of the top security concerns for Europe. Depleting reserves and growing energy demand have increased European dependence on external energy resources. Today, Russia is by far the largest supplier of oil, coal and the natural gas to Europe. Oil and natural gas revenues have played a vital role to rebound the Russian economy and have supported Putin’s ambitions to reestablish Russia as a great power, increasing its influence over the former Soviet space. This complex energy relationship has increasingly been a cause of concern.

The main question this study seeks to answer …


Frequency Agile Ofdm System For Radio Communication In High Frequency Bands, Erin E. Hill May 2022

Frequency Agile Ofdm System For Radio Communication In High Frequency Bands, Erin E. Hill

Electrical & Computer Engineering Theses & Dissertations

High Frequency (HF) radio communication existed as the primary source of over-the-horizon communication for decades prior to the wide implementation of satellite and cellular networks. Even today, should satellite communication become unavailable, the robust backup of HF vitally supports long distance data transmission without the need of a cellular infrastructure. This capability is of particular importance to naval applications while at sea. Frequency choice, however, becomes critical in supporting reliable HF communication as too high of a frequency will not return to earth and too low of a frequency will result in high absorption rates within the atmosphere. A potential …


Putin And Putnam: Interpreting Russian Military Activity Through A Three Player, Two-Level Game, Nathan M. Colvin Apr 2022

Putin And Putnam: Interpreting Russian Military Activity Through A Three Player, Two-Level Game, Nathan M. Colvin

Modeling, Simulation and Visualization Student Capstone Conference

Is Vladimir Putin a bad strategist, perhaps irrational? Previous military activity by Russia, such as the annexation of Crimea of 2014, yielded limited international gains, at a significant economic and reputational cost. Yet as the 2022 invasion of Ukraine shows, Putin is willing to commit military power, despite the cost of sanctions and other possible retaliation. This three-player simultaneous game, originally created in June, 2021, demonstrates how domestic and international considerations of President Vladimir Putin might lead to otherwise unpredictable Russian military behavior. In this extended version of Robert Putnam’s “two-level game,” President Putin rationally uses the international venue as …

Exploring Blockchain Adoption Supply Chains: Opportunities And Challenges, Adrian V. Gheorghe, Omer F. Keskin, Farinaz Sabz Ali Pour

Engineering Management & Systems Engineering Faculty Publications

In modern supply chains, acquisition often occurs with the involvement of a network of organizations. The resilience, efficiency, and effectiveness of supply networks are crucial for the viability of acquisition. Disruptions in the supply chain require adequate communication infrastructure to ensure resilience. However, supply networks do not have a shared information technology infrastructure that ensures effective communication. Therefore decision-makers seek new methodologies for supply chain management resilience. Blockchain technology offers new decentralization and service delegation methods that can transform supply chains and result in a more flexible, efficient, and effective supply chain. This report presents a framework for the application …

An Examination Of Motives, Attitudes And Charitable Intentions For Running In A Charity Event, Edwin Gomez, Eddie Hill, Lynn Ridinger, Stephen Shiparo

Human Movement Studies & Special Education Faculty Publications

Running, as a form of leisure time physical activity is generally popular due to its low-cost entry, easy access to practice, and the convenience and accessible nature of the activity. Specifically, one type of running experience sought by many is charitable running or running for a cause (i.e., cause-related sport event). While there is a growing body of literature on charity sport events, little is known about how the charitable motives and participant identity with the event affect future behaviors associated with the cause and the event. Grounded in identity theory, the purpose of this article was to examine the …

Experiences With Flood And Perceptions Of Flood Risk Among Members Of The Filipino American Community In Virginia Beach, Virginia, Anjelica Pascual Petsch Dec 2021

Experiences With Flood And Perceptions Of Flood Risk Among Members Of The Filipino American Community In Virginia Beach, Virginia, Anjelica Pascual Petsch

Institute for the Humanities Theses

The Filipino Americans living in Hampton Roads, Virginia have comprised of almost 2% of the region’s overall population, and 5.3% of the population in Virginia Beach, Virginia (United States Census Bureau, 2019) (Greater Hampton Roads Connects, 2021). Filipino Americans in Hampton Roads, like the rest of the population, are equally vulnerable to experiencing flooding when commuting to and from work or simply traveling around town, but previous research and surveys from the Hampton Roads Region have failed in their ability to capture this cultural diversity within perception of flood risk. In this paper, a qualitative research design was used to …


Language And Cultural Identity In Post-Soviet Frozen Conflicts, Irina Paquette Dec 2021

Language And Cultural Identity In Post-Soviet Frozen Conflicts, Irina Paquette

Graduate Program in International Studies Theses & Dissertations

How we, as humans, define ourselves and our national and ethnic distinction often centers on visible characteristics—physical features, group traditions, and language. Of those, language is both mutable and plays such a central role in daily life that it is often a hotly contested and manipulated factor in defining national identity. This paper examines the role language has played in the formation of crisis situations in the former Soviet Union. Linguistic identity has been used as a basis to establish the legitimacy of independence for both Soviet republics and separatist groups within those republics. As such, it is a highly …


The Maritime Domain Awareness Center– A Human-Centered Design Approach, Gary Gomez Nov 2021

The Maritime Domain Awareness Center– A Human-Centered Design Approach, Gary Gomez

Political Science & Geography Faculty Publications

This paper contends that Maritime Domain Awareness Center (MDAC) design should be a holistic approach integrating established knowledge about human factors, decision making, cognitive tasks, complexity science, and human information interaction. The design effort should not be primarily a technology effort that focuses on computer screens, information feeds, display technologies, or user interfaces. The existence of a room with access to vast amounts of information and wall-to-wall video screens of ships, aircraft, weather data, and other regional information does not necessarily correlate to possessing situation awareness. Fundamental principles of human-centered information design should guide MDAC design and technology selection, and …


Smart Power In The Iraq Surge 2007-2008, Russell N. Reiling Jul 2021

Smart Power In The Iraq Surge 2007-2008, Russell N. Reiling

Graduate Program in International Studies Theses & Dissertations

This dissertation explores U.S. actions in the military “Surge” in Iraq from 2007-2008. Focus is on the entwined utilization of coercive and attractive power or smart power as an enabler of success and change from prior U.S. strategies in Operation IRAQI FREEDOM. The analysis is based upon an extensive set of interviews with operational participants in the Surge from across the Executive Branch. Results show that smart power was an important element of the Surge and its use facilitated success, but that doing smart power was not a simple matter of achieving some mix of ‘hard’ and ‘soft’ power, but …


Connectivism: Adopting Quantum Holism In International Relations, Grant Randal Highland Jul 2021

Connectivism: Adopting Quantum Holism In International Relations, Grant Randal Highland

Graduate Program in International Studies Theses & Dissertations

The current scientific context of both quantum science and an ever-increasingly connected global citizenry has set the conditions for a new perspective whereby the social sciences are on the cusp of adopting a quantum approach of probability and potentiality versus the clockwork mechanistic determinism of cause-and-effect Newtonian mechanics. While a scientific realist approach toward the application of quantum science to the social sciences is germane, there is a valid reason international relations should also consider and adopt the philosophical worldviews outside the genealogical canon of our early western forbears, as well as the philosophical explorations of consciousness and humanism which …

Blockchain For A Resilient, Efficient, And Effective Supply Chain, Evidence From Cases, Adrian Gheorghe, Farinaz Sabz Ali Pour, Unal Tatar, Omer Faruk Keskin

Engineering Management & Systems Engineering Faculty Publications

In the modern acquisition, it is unrealistic to consider single entities as producing and delivering a product independently. Acquisitions usually take place through supply networks. Resiliency, efficiency, and effectiveness of supply networks directly contribute to the acquisition system's resiliency, efficiency, and effectiveness. All the involved firms form a part of a supply network essential to producing the product or service. The decision-makers have to look for new methodologies for supply chain management. Blockchain technology introduces new methods of decentralization and delegation of services, which can transform supply chains and result in a more resilient, efficient, and effective supply chain. This …

Generation Of Excited Species In A Streamer Discharge, Shirshak K. Dhali Jan 2021

Generation Of Excited Species In A Streamer Discharge, Shirshak K. Dhali

Electrical & Computer Engineering Faculty Publications

At or near atmospheric pressure, most transient discharges, particularly in molecular gases or gas mixture containing molecular gases, result in a space charge dominated transport called a streamer discharge. The excited species generation in such discharges forms the basis for plasma chemistry in most technological applications. In this paper, we simulate the propagation of streamers in atmospheric pressure N2 to understand the energy partitioning in the formation of various excited species and compare the results to a uniform Townsend discharge. The model is fully two-dimensional with azimuthal symmetry. The results show a significantly larger fraction of the energy goes …


Transient Behavior Of Drift And Ionization In Atmospheric Pressure Nitrogen Discharge, S. K. Dhali Jan 2021

Transient Behavior Of Drift And Ionization In Atmospheric Pressure Nitrogen Discharge, S. K. Dhali

Electrical & Computer Engineering Faculty Publications

The fluid models are frequently used to describe a non-thermal plasma such as a streamer discharge. The required electron transport data and rate coefficients for the fluid model are parametrized using the local field approximation (LFA) in first order models and the local-mean-energy approximation (LMEA) in second order models. We performed Monte Carlo simulations in Nitrogen gas with step changes in the E/N (reduced electric field) to study the behavior of the transport properties in the transient phase. During the transient phase of the simulation, we extract the instantaneous electron mean energy, which is different from the steady state mean …

Covid-19 And Biocybersecurity's Increasing Role On Defending Forward, Xavier Palmer, Lucas N. Potter, Saltuk Karahan

Electrical & Computer Engineering Faculty Publications

The evolving nature of warfare has been changing with cybersecurity and the use of advanced biotechnology in each aspect of the society is expanding and overlapping with the cyberworld. This intersection, which has been described as “biocybersecurity” (BCS), can become a major front of the 21st-century conflicts. There are three lines of BCS which make it a critical component of overall cybersecurity: (1) cyber operations within the area of BCS have life threatening consequences to a greater extent than other cyber operations, (2) the breach in health-related personal data is a significant tool for fatal attacks, and (3) health-related misinformation …


Stratified Security Communities: Transatlantic Distrust And Identity Divergence, Afra Maike Herr Dec 2020

Stratified Security Communities: Transatlantic Distrust And Identity Divergence, Afra Maike Herr

Graduate Program in International Studies Theses & Dissertations

With mounting pressure by the United States directly and through their strategic shift and slow abdication of leadership towards Asia and away from the transatlantic community, European states have growing incentive to cooperate more strongly and integrate their defense and security efforts. The absence of such a trend of integration points to internal barriers to growing cooperation countering the external dynamic. Utilizing the theory of security communities, this thesis explores German, French, and British understanding of leadership, defense, and their respective public opinions. Focusing on the security identities of all three nations and their visions for the community as well …


A Rivalry Of Necessity: An Analysis Of Mechanisms Of Contention Between The Islamic Republic Of Iran And The Kingdom Of Saudi Arabia, Aras Syahmanssuri Dec 2020

A Rivalry Of Necessity: An Analysis Of Mechanisms Of Contention Between The Islamic Republic Of Iran And The Kingdom Of Saudi Arabia, Aras Syahmanssuri

Graduate Program in International Studies Theses & Dissertations

The 1979 Iranian Islamic revolution that extremely concerned the Saudis leaders culminated after the overthrow of a monarchical regime of the Iranian Shah and the power rise of a theocratic Shia government led by Ayatollah Khomeini. From the early days of this revolution, Khomeini raised a unique slogan, which was “exporting the revolution” to neighboring countries. Through targeting the Shia minority in neighboring countries, this slogan highly concerned the Gulf countries including the Kingdom of Saudi Arabia. Examining four decades of hostility, which starts from the 1979 Islamic Revolution of Iran, this study indicates that the rivalry between the Islamic …
