Cyber Threats, Cyber Risks, And Cybersecurity Responses: Modeling Whole-Of-Nation Strategy Implementation For American Organizations And Citizens, Vincent Leon Guerrero
Cyber Threats, Cyber Risks, And Cybersecurity Responses: Modeling Whole-Of-Nation Strategy Implementation For American Organizations And Citizens, Vincent Leon Guerrero
All Dissertations
Amid a landscape of cyber attacks on America occurring below the threshold of armed conflict, strategic national policy efforts recommend a whole-of-nation approach where individuals and public and private organizations increase their defensive posture in cyberspace. Motivation to address the risk of a cyber event includes a continuum of cyber threats that can range from low-level disruptive events to cybercrime and cyber espionage to the possibility of a potentially catastrophic attack on critical infrastructure. In this dissertation, I conduct a survey experiment of various cyber threat conditions and cyber policies to model cybersecurity responses, risk perceptions to a possible cyber …

We Train Ai, Why Not Humans, Too? An Exploration Of Human-Ai Team Training For Future Workplace Viability, Caitlin M. Lancaster
All Dissertations
The integration of Artificial Intelligence (AI) in the workforce is transforming team dynamics, leading to the emergence of Human-AI Teams (HATs). These teams offer opportunities to capitalize on human strengths with AI's prowess, offering significant opportunities for innovation and efficiency. Effective HAT functioning requires aligning human expectations with AI capabilities and bridging knowledge gaps between teammates. Despite this potential, key integration challenges remain, such as developing shared mental models, addressing skill limitations, and overcoming negative AI perceptions. Existing training efforts often apply human-human teaming principles directly to HATs, overlooking AI's role as a teammate and limiting the development of HAT-specific …

Enhanced Optical And Infrared Activity Of Nanosphere Dimers Attributed To Dimer Geometry, D. Keith Roper, Jin-Woo Kim, Ricardo R. Romo, Joseph Batta-Mpouma
Biological and Agricultural Engineering Faculty Publications and Presentations
Enhanced optical and infrared activity of subwavelength metal nanoparticles is key to their use in optoelectronics, spectroscopy, and sensing. The present work compared spectra of nanosphere dimers merged by centrifuging gold nanospheres with corresponding simulated nanoscale dimers. Geometric features of the nanosphere dimers were related to corresponding optical and near-infrared activity through simulation. Differences in optical and infrared activity of the nanosphere dimers were largely attributable to changes in the radius of the nanosphere and the radius of the conductive junction between merged nanospheres. The features observed in the experimental spectra were attributed to a select number of dimers exhibiting …

American Sanctions On China's Space Program: Effective Economic Statecraft?, Paul J. Bolt
Space and Defense
American economic statecraft as a tool to manage competition with China’s Space Program is likely to remain contentious as it amplifies enduring debates in U.S. foreign policy: i) the tension between international realism and American liberalism; ii) the questionable benefit of government involvement in picking winners and losers from the private sector; and iii) the difficulty of defining long-term success in foreign policy outcomes.

Pushing Boundaries: Feminism, Female Leaders, And The Fate Of Feminist Foreign Policy, Sannia Abdullah
Space and Defense
The study challenges the clearest, unqualified liberal claim on feminist foreign policy: namely, women equal peace and security while men equal war. In fact, women approach foreign policy challenges as judiciously as men and have proven their statesmanship. Feminist foreign policy promotes gender equality, women empowerment, and socio-economic parity based on a non-hierarchal system, but it fails to offer a resilient, conflict preventing, and environmentally friendly alternative framework capable of reducing contemporary foreign policy challenges.

Atrocity Prevention In The Digital Era: Adapting Norms, Laws, And Code To Changes In The Ways Atrocities Are Committed, David J. Simon, Samhitha Josyula, Joshua Lam, Julian D. Melendi
Genocide Studies and Prevention: An International Journal
Emerging digital technologies have changed some of the ways that genocides are planned and executed. This paper examines those differences, calling attention to how changes in the execution of genocide should prompt a shift in the approaches to atrocity prevention. It develops a conceptual framework addressing how atrocity prevention efforts might adapt to new technology within three realms of potential prevention efforts: the ethical (norms), the legal (laws), and the digital (code).

Security Or Vulnerability? The Optics Of Data In The Humanitarian Sphere, Nicole M. Bennett, Hamid Ekbia
Genocide Studies and Prevention: An International Journal
Governments, humanitarian agencies, and non-government organizations increasingly resort to data-driven techniques to meet the challenges they face in dealing with growing mobile populations such as refugees. Such techniques originate in bureaucratic administrations of the 19th century and, even earlier, in slave trade and plantation accounting methods. They were then perfected in logistics and global supply chain management of the twentieth and twenty-first centuries, especially with the advent of information technology. We examine the application of these techniques in humanitarian cases, seeking to contextualize them within the framework of logistic security. To understand the drivers of this trend, we introduce the …

Writing About A Stressful Experience Can Impair Visual Working Memory, Colton Hunter, Grant S. Shields
Psychological Science Faculty Publications and Presentations
Acute stress has been well-established to impair working memory. However, less is known about how writing about an unresolved stressor may influence working memory or working memory processes. We addressed these issues in the present study (N = 282) by randomly assigning participants to write about an unresolved stressful experience (stressful writing condition or the events of the previous day). We then both measured performance on a change detection task and used computational modeling to estimate the processes underlying performance: attention, capacity, and guessing bias. We found that, relative to the control condition, writing about a stressful experience impaired …

The Blessed Assembly: Irreplaceable Physical Co-Presence In Worship And Healthy Hybridity Reimagined After The Pandemic In The Digital Age, Yvette, Ying Wai Lau
Doctor of Pastoral Music Projects and Theses
Because of the unprecedented and unexpected force of the pandemic since 2020, most churches around the world have experienced some online worship during the lockdown of their cities or the mandated closure of the church buildings. For many people, online worship seems to be an equivalent, if not better, alternative for gathering together—a physical co-presence in worship—even after the pandemic has ended. As necessary and vital as online worship experiences have been for Christians during the pandemic, the witness of the church from Pentecost throughout Christian history indicates that gathered worship in physical spaces is irreplaceable for faith formation and …

Virtual Fencing In Livestock Management: Effects On Beef Cattle Stress And Enhancing Wildlife Conservation, Kaitlyn E. Dozler
School of Natural Resources: Dissertations, Theses, and Student Research
I examined the effects of virtual fencing on beef cattle stress and how implementing the technology can aid wildlife habitat conservation at the University of Nebraska Gudmundsen Sandhills laboratory (GSL) near Whitman, NE. First, I examined how virtual fencing influences acute heart rate changes in beef cattle fitted with the virtual fencing collars. No significant difference in the average heart rate of a cow (P > 0.05) was observed between the 30 min control and virtual fenced periods for both trial dates. Second, I examined the influence of topography on wildlife species richness and presence at GSL using wildlife camera …

The recent surge in the plant-based protein market has resulted in high demands for soybean genotypes with improved grain yield, seed protein and oil content, and essential amino acids (EAAs). Given the quantitative nature of these traits, complex interactions among seed components, as well as between seed components and environmental factors and management practices, add complexity to the development of desired genotypes. In this study, the across-environment seed protein stability of 449 genetically diverse plant introductions was assessed, revealing that genotypes may display varying sensitivities to such environmental stimuli. The EAAs valine, phenylalanine, and threonine showed the highest variable importance …

Recent developments in 2D magnetic materials have motivated the search for new van der Waals magnetic materials, especially Ising-type magnets with strong magnetic anisotropy. Fe-based MPX3 (M = transition metal, X = chalcogen) compounds such as FePS3 and FePSe3 both exhibit an Ising-type magnetic order, but FePSe3 receives much less attention compared to FePS3. This work focuses on establishing the strategy to engineer magnetic anisotropy and exchange interactions in this less-explored compound. Through chalcogen and metal substitutions, the magnetic anisotropy is found to be immune against S substitution for Se whereas …

Machine Ex Machina: A Framework Decentering The Human In Ai Design Praxis, Cait Lackey, Zizi Papacharissi
Human-Machine Communication
Artificial intelligence (AI) design typically incorporates intelligence in a manner that is affirmatory of the superiority of human forms of intelligence. In this paper, we draw from relevant research and theory to propose a social-ecological design praxis of machine inclusivity that rejects the presumption of primacy afforded to human-centered AI. We provide new perspectives for how human-machine communication (HMC) scholarship can be synergistically combined with modern neuroscience’s integrated information theory (IIT) of consciousness. We propose an integrated theoretical framework with five design practice recommendations to guide how we might think about responsible and conscious AI environments of the future: symbiotic …

Exploring Cultural, Health, And Technology Intersections: A Focus On Migrant Experiences, Merna Mina, Sahij Gill
Bridges: An Undergraduate Journal of Contemporary Connections
Despite the plethora of theories and frameworks addressing culture, health, and technology adoption, there remains a notable absence of a unifying theory that comprehensively encompasses all three aspects, particularly concerning newcomers. The Health Belief Model, for example, underscores individual perceptions and attitudes toward health yet fails to consider the intricate interplay between cultural factors and technology adoption among immigrant populations. The Healthy Immigrant Effect, which posits that immigrants often exhibit better health outcomes than native-born individuals, does not mention the role of technology on health outcomes. Acculturation theories, while shedding light on the adaptation process, often fall short of explaining …

Many people own online accounts, with some having financial values like Internet banking, e-wallet and cryptocurrency. In the case of sudden death, their heirs are unaware of the digital assets possessed by the deceased person, which causes the assets to be lost forever, and the heirs might not receive the assets. If an estate plan did not account for digital assets properly, the beneficiaries would not be able to access them. Therefore, this paper addresses this issue by implementing a software development approach in designing a suitable model for sustaining digital assets through smartphones to allow the inheritance of digital …
