Hybrid Deep (Cnn-Bilstm) Intrusion Detection For Defense And Mission-Critical Networks, Corey A Cheng, Jermaine Anim-Addo, Asma Jakir Hussain, Zion O Smith-Fox, Sanjay Goel, Yuksel Celik
Military Cyber Affairs
This article examines how hybrid deep learning can strengthen intrusion detection for military and defense networks. Using the CSE-CIC-IDS2018 dataset, the study evaluates a CNN-BiLSTM model designed to detect benign traffic and multiple attack categories, including DDoS, DoS, botnet, brute-force, web attack, and infiltration activity. The model achieved strong multi-class detection performance, with 0.9893 accuracy and 0.9979 ROC-AUC. The findings suggest that AI-supported intrusion detection can improve cyber defense operations, analyst triage, and protection of mission-critical networks.

Governing Algorithmic Attention: Attention Safeguard Models And The Cognitive Attentional Standard As System Level Interventions In Human Computer Interaction, Behavioral Economics, And Artificial Intelligence, Delante Clark
Graduate Scholarship and Creative Works
Algorithmic recommendation systems and interface designs shape attention by combining visually salient cues with uncertain reward timing and low friction interaction. These conditions can sustain anticipatory checking, extend time on task, and reduce natural disengagement points through patterns such as infinite scrolling and autoplay. This paper synthesizes research across neuroscience, human computer interaction, behavioral economics, and artificial intelligence to argue that attention capture is a predictable outcome of incentive driven design rather than an individual failure of self regulation. It advances the Attention Safeguard Models and the Cognitive Attentional Standard as system level interventions that regulate exposure conditions, pacing, and …
The Legacy Of Lead: Lead Exposure's Harmful Effects And Its Concentration In Poc Communities, Layla Sophronia Barber
The Legacy Of Lead: Lead Exposure's Harmful Effects And Its Concentration In Poc Communities, Layla Sophronia Barber
Student Theses 2015-Present
This thesis examines the disproportionate burden of lead exposure carried by low income, POC communities. The systemic nature of this problem is a symptom of a longstanding legacy of environmental injustice in the United States. Decades of federal neglect are reflected in the higher statistics of lead exposure and poisoning in predominantly black communities. While it is understood that lead exposure poses a serious threat to physical health and early cognitive development, there is a discouraging lack of urgency to remove the toxin from non-wealthy communities. The material covered by this thesis aims to identify and correct the discriminatory social …
Organizing To Engage: A Framework For Conflict Strategy, Paul Mason Carpenter
Organizing To Engage: A Framework For Conflict Strategy, Paul Mason Carpenter
Dissertations
Conflict strategy can be exceedingly complex. While many of the basics are simple, even the simple can be highly complicated to execute. The Schlieffen Plan in World War I appeared straight forward, but execution was a great deal more complex. It failed and the result was years of trench warfare. In addition, leaders entering conflict may not fully appreciate the full context, its effect, and the need for a long term result--a better state of peace.
Strategy and tactics may be challenging to transform as an engagement evolves. In addition, strategists must often commit to courses of action within very …

C.A.S. Full Assessment Report: State Of Florida Government Portal, Delante Clark
Graduate Scholarship and Creative Works
The purpose of this assessment is to evaluate the cognitive overhead, transparency, and attentional integrity of
official State of Florida digital interfaces using the Cognitive Attentional Standards (C.A.S.) platform.
While the Florida Digital Bill of Rights (FDBR) establishes strict regulatory guardrails for consumer data
transparency, tracking opt-outs, and attentional safeguards, the State of Florida explicitly exempts its own
government agencies, public universities, and non-profit entities from complying with these rules.
This assessment serves to investigate the tension between legislative intent and government execution. By
analyzing public sector websites through the C.A.S. platform, this project will establish a “state-enforced vs.
state-executed” …
Politics As Usual: Racial Pay Inequity And The Illusion Of Inclusion In The Rise And Fall Of Diversity, Equity, Inclusion, And Accessibility Executive Orders, Francois C. Melville
Politics As Usual: Racial Pay Inequity And The Illusion Of Inclusion In The Rise And Fall Of Diversity, Equity, Inclusion, And Accessibility Executive Orders, Francois C. Melville
West Chester University Graduate Theses, Dissertations, and Final Projects
This research examines pressing moral policy questions of our time: who determines when the United States of America has fulfilled its broken promise of equality for all, and what constitutes an appropriate measure of reparative justice. It interrogates why the Diversity, Equity, and Inclusion (DEI) Executive Orders (EOs) implemented across presidential administrations, intended to advance social equity, were grounded in conflict and symbolic gestures rather than scientifically evidenced issues such as wage inequality directly linked to upward career mobility. Race conscious policy generates cultural clashes centered on the perception that gains made by Black and Brown Americans come at the …

This paper introduces a method to quantify international populations’ susceptibility to cyber cognitive attacks using press freedom and media trust metrics. We present the Cognitive Influence Calculator, a tool that estimates susceptibility (𝑆) based on Press Freedom Scores (PFS) and media trust levels. Findings show that while authoritarian regimes are harder to reach, successful cognitive attacks have greater impacts due to higher trust in state-controlled narratives. Using U.S. wargaming data and international trust metrics, we compute susceptibility scores for the U.S., Russia, China, Iran, and North Korea. Results show an inverse relationship between PFS and media susceptibility, with local/allied …

Characterizing Cyberattacks Against Operational Technology Infrastructures Through The Lens Of Attack Flows, Sherman Kettner, Caleb Chang, Ekzhin Ear, Shouhuai Xu
Military Cyber Affairs
Operational Technology (OT) infrastructures play a critical role in modern society and economy. However, their increasing connectivity with public networks such as the Internet has made them vulnerable to cyberattacks, much like traditional Information Technology (IT) systems. In particular, cyberattacks against OT infrastructures remain relatively underexplored and little understood. In this paper, we aim to deepen our understanding of cyberattacks against OT infrastructures. For this purpose, we propose a methodology, including novel cybersecurity metrics to analyze the attack flows of these attacks in an end-to-end fashion, which allows us to draw useful insights. We demonstrate the utility of the methodology …
Challenging Beliefs: Examining The Efficacy Of Corrections For Conspiratorial And Partisan Misinformation, Ava Zwolinski
Challenging Beliefs: Examining The Efficacy Of Corrections For Conspiratorial And Partisan Misinformation, Ava Zwolinski
Dissertations, Theses, and Capstone Projects
The threat of misinformation is widely acknowledged among researchers and laypeople (NORC, 2021). When misinformation coalesces with conspiracy theories, the repercussions can be especially dangerous, sometimes even fatal. Events such as the January 6th insurrection and the Buffalo Tops Supermarket shooting were both, in part, inspired by misleading information and conspiracy theories (Burke, 2022; Dawsey, 2023). While misinformation involving conspiracy theories is recognized as possibly posing a greater threat to correction efforts (Lewandowsky, 2021a), no study has yet experimentally manipulated the presence or absence of conspiratorial elements within misinformation. This dissertation explores whether conspiratorial misinformation is more difficult to correct …

Military Cyber Affairs
Understanding of the intersection of cyber vulnerabilities and bioprocess regulation is critical with the rise of artificial intelligence and machine learning in manufacturing. We detail a case study in which we model cyberattacks on network-mediated signals from a novel bioreactor, where it is important to control medium feed rates to maintain cell proliferation. We use a digital twin counterpart reactor to compare glucose and oxygen sensor signals from the bioreactor to predictions from a kinetic growth model, allowing discernment of faulty sensors from hacked signals. Our results demonstrate a successful biomanufacturing cyberattack detection system based on fundamental process control principles.
Tunisian Democracy At A Crossroads: A Comparative Analysis Of Beji Caid Essebsi And Kais Saied Regimes, Nizar Lukman
Tunisian Democracy At A Crossroads: A Comparative Analysis Of Beji Caid Essebsi And Kais Saied Regimes, Nizar Lukman
Jurnal Politik
As a new democracy, Tunisia is quite vulnerable to democratic erosion. The implementation of democracy in the country was quite effective during the leadership of Beji Caid Essebsi, resulting in a high democracy index driven by various policies that supported the implementation of this system. However, Tunisia’s quality of democracy significantly declined since President Kais Saied took power in 2019. The dissolution of Parliament, the prime minister's dismissal, the introduction of freedom of expression for council members, and unilateral electoral reforms aimed at consolidating his power are some cases of proof. This pattern raises questions about the recurring nature of …
Identifying Youth Appeals In Alcohol Alternative Social Media Content Through Framing, Melina Oneal
Identifying Youth Appeals In Alcohol Alternative Social Media Content Through Framing, Melina Oneal
West Chester University Master’s Theses
Proposed regulations for alcohol advertising prevent beverage companies from targeting people under the legal drinking age. However, similar regulations for alcohol alternative beverages are less explored, which could allow alcohol alternative products to create awareness for alcoholic beverages among youth. Alcohol alternatives beverages, including no-alcohol and low-alcohol products, are increasing in popularity and can function as compliments to alcoholic products to decrease the total alcohol volume consumed or as substitutes for alcoholic products. Framing theory can be operationalized through the Content Appealing to Youth Index, an index of content elements found in research literature to be appealing to youth, to …

This thesis explores Western media's representation of the United Nations (UN), focusing on the Security Council's role in global conflict resolution. It examines how UN-accredited correspondents perceive the effectiveness of the Security Council, particularly when the body faces deadlock. The study employs text analysis techniques to identify biases and perceptions in media coverage, using The New York Times' reporting on the Ukraine conflict as a case study. It illuminates framing effects in journalistic narratives, revealing how journalists subtly interject their views when reporting, often revealing unrealistic expectations and shedding light on the limitations of the UN's mandate or its inability …
Clausewitzian Theory Of War In The Age Of Cognitive Warfare, Amber Brittain-Hale, Amber Brittain-Hale
Clausewitzian Theory Of War In The Age Of Cognitive Warfare, Amber Brittain-Hale, Amber Brittain-Hale
Education Division Scholarship
We can reconceptualise warfare by contrasting Clausewitz with the modern practice of cognitive warfare, as evidenced by Ukraine’s defence methodologies. The strategic orchestration of ‘infopolitik’ and the sophisticated use of social media can shape narratives and public perception. This article revisits Clausewitz’s tenet of war as a political instrument and juxtaposes it with contemporary conflict’s multidimensional tactics. By scrutinising Ukraine’s digital and psychological warfare tactics, one may question the applicability of Clausewitz’s framework, seeking to understand if these novel dimensions of warfare compel a redefinition or an expansion of his thesis to navigate the complexities of contemporary geopolitical confrontations.
The Politics Of Expertise And The Articulation Of Authority In Democracy: Cognitive Style And Intelligibility In The Education Of Problem-Solving And Professional Decision-Making In The Domain Of Law, Michael W. Raphael
Dissertations, Theses, and Capstone Projects
Computational complexity refers to the representational aspect of problem-solving. This representational aspect is commonly understood to describe the regularities that organize the definition of the problem-situation, the qualities that designate its difficulty, either in terms of the process of arriving at a definition of the problem or in the process of arriving at a solution. It is for this reason, that it is commonly said that “representational design precedes computational efficacy.” The point of this maxim is to serve as a reminder that an efficient use of resources begins with the design of near decomposability, the specification of the properties …

Industrial Control Systems (ICS) are widely used by critical infrastructure and are ubiquitous in numerous industries including telecommunications, petrochemical, and manufacturing. ICS are at a high risk of cyber attack given their internet accessibility, inherent lack of security, deployment timelines, and criticality. A unique challenge in ICS security is the prevalence of serial communication buses and other non-TCP/IP communications protocols. The communication protocols used within serial buses often lack authentication and integrity protections, leaving them vulnerable to spoofing and replay attacks. The bandwidth constraints and prevalence of legacy hardware in these systems prevent the use of modern message authentication and …
