The Influence Of An Individual’S Disposition To Value Privacy In A Non-Contrived Study, John Marsh Jan 2021

The Influence Of An Individual’S Disposition To Value Privacy In A Non-Contrived Study, John Marsh

CCE Theses and Dissertations

Unexpected usage of user data has made headlines as both governments and commercial entities have encountered privacy-related issues. Like other social networking sites, LinkedIn provides users to restrict access to their information or allow for public viewing; information available in the public view was used unexpectedly (i.e., profiling). A non-profit entity called ICWATCH used tools to gather information on government mass surveillance programs by scraping publicly accessible user data from LinkedIn. Previous research has shown that privacy concerns influence behavior intention in contrived scenarios. What remains unclear is whether LinkedIn users, whose data was scraped by ICWATCH (an actual situation), …


Orientation And Social Influences Matter: Revisiting Neutralization Tendencies In Information Systems Security Violation, Frank Curtis King Jan 2021

Orientation And Social Influences Matter: Revisiting Neutralization Tendencies In Information Systems Security Violation, Frank Curtis King

CCE Theses and Dissertations

It is estimated that over half of all information systems security breaches are due directly or indirectly to the poor security practices of an organization’s employees. Previous research has shown neutralization techniques as having influence on the intent to violate information security policy. In this study, we proposed an expansion of the neutralization model by including the effects of business and ethical orientation of individuals on their tendencies to neutralize and compromise with information security policy. Additionally, constructs from social influences and pressures have been integrated into this model to measure the impact on the intent to violate information security …

The Construction And Internal Validation Of A Model For The Effective Collaboration Of Distributed Agile Teams, Ernesto Custodio

CCE Theses and Dissertations

Agile approaches to software development have increased steadily over the past decade. Agile processes emphasize iterative and collaborative discovery of requirements and solutions executed by self-organizing, cross-functional teams. Software development using distributed teams, including distributed sub-teams, fully dispersed teams, and partially dispersed teams, has also increased due to benefits such as access to global talent and faster delivery, among others.

However, most Agile approaches, models, and frameworks only address the needs of colocated teams. Distributed teams come with unique challenges when it comes to effective collaboration. The goal was to construct and validate internally a model for the effective collaboration …


Neural Network Variations For Time Series Forecasting, David Ason Jan 2021

Neural Network Variations For Time Series Forecasting, David Ason

CCE Theses and Dissertations

Time series forecasting is an area of research within the discipline of machine learning. The ARIMA model is a well-known approach to this challenge. However, simple models such as ARIMA do not take into consideration complex relationships within the data and quite often fail to produce a satisfactory forecast. Neural networks have been presented in previous works as an alternative. Neural networks are able to capture non-linear relationships within the data and can deliver an improved forecast when compared to ARIMA models.

This dissertation takes neural network variations and applies them to a group of time series datasets found in …

Pause For A Cybersecurity Cause: Assessing The Influence Of A Waiting Period On User Habituation In Mitigation Of Phishing Attacks, Amy Antonucci

CCE Theses and Dissertations

Social engineering costs organizations billions of dollars a year. Social engineering exploits the weakest link of information security systems, the people who are using them. Phishing is a form of social engineering in which the perpetrator depends on the victim’s instinctual thinking towards an email designed to create a fear or excitement response. It is well-documented in literature that users continue to click on phishing emails costing them and their employers significant monetary resources and data loss. Training does not appear to mitigate the effects of phishing much; other solutions are necessary to mitigate phishing.

Kahneman introduced the concepts of …

To accomplish this, a semi-structured interview was distributed to healthcare executives. The semi-structured interview …


Investigating The User Experience With A 3d Virtual Anatomy Application, Winnyanne Kunkle Jan 2021

Investigating The User Experience With A 3d Virtual Anatomy Application, Winnyanne Kunkle

CCE Theses and Dissertations

Decreasing hours dedicated to teaching anatomy courses and declining use of human cadavers have spurred the need for innovative solutions in teaching anatomy in medical schools. Advancements in virtual reality (VR), 3D visualizations, computer graphics, and medical graphic images have enabled the development of highly interactive 3D virtual applications. Over recent years, variations of interactive systems on computer-mediated environments have been used as supplementary resource for learners. However, despite the growing sophistication of these resources for learning anatomy, studies show that students predominantly prefer traditional methods of learning and hands-on cadaver-based learning over computer-mediated platforms.

There is limited research on …

Examination Of Corporate Investments In Privacy: An Event Study, Joseph Michael Squillace

CCE Theses and Dissertations

The primary objective of any corporate entity is generating as much wealth as possible. Investing financially in technology domains has historically been a successful strategy for generating increased corporate and shareholder wealth. However, investments in Information Technology (IT), Information Systems (IS) and Information Security (InfoSec) to specifically generate increased wealth must be implemented carefully.

Shareholders reacting to corporate investments perceive financial value from individual investments. The investment’s perceived value is then reflected in the corporation’s updated stock market value. IS, IT, and InfoSec investments perceived to possess positive financial value, indicating strong potential for increased wealth, are rewarded by shareholders …

Examining The Influence Of Perceived Risk On The Selection Of Internet Access In The U.S. Intelligence Community, Tyler Michael Pieron

CCE Theses and Dissertations

Information technology security policies are designed explicitly to protect IT systems. However, overly restrictive information security policies may be inadvertently creating an unforeseen information risk by encouraging users to bypass protected systems in favor of personal devices, where the potential loss of organizational intellectual property is greater.

Current models regarding the acceptance and use of technology, Technology Acceptance Model Version 3 (TAM3) and the Unified Theory of Acceptance and Use of Technology Version 2 (UTAUT2), address the use of technology in organizations and by consumers, but little research has been done to identify an appropriate model to begin to understand …


Investigation Of Ant Colony Optimization Implementation Strategies For Low-Memory Operating Environments, Douglas Hale Jan 2021

Investigation Of Ant Colony Optimization Implementation Strategies For Low-Memory Operating Environments, Douglas Hale

CCE Theses and Dissertations

In search guided by meta-heuristics, a fundamental tradeoff exists between exploitation of good solutions (intensification) and exploration of the solution space for better solutions (diversification). Over-exploitation can limit the search to suboptimal solutions while over-exploration can reduce the efficiency of the overall search. Ant Colony Optimization (ACO) is a well-known meta-heuristic inspired by biological ants for solving NP-hard combinatorial search problems like the Traveling Salesman Problem (TSP). In nature, biological ant colonies navigate to find efficient paths around complex obstacles by depositing and following simple chemicals called pheromones. ACO algorithms model this behavior by implementing sets of artificial ants which …

Increasing Software Reliability Using Mutation Testing And Machine Learning, Michael Allen Stewart Jan 2021

Increasing Software Reliability Using Mutation Testing And Machine Learning, Michael Allen Stewart

CCE Theses and Dissertations

Mutation testing is a type of software testing proposed in the 1970s where program statements are deliberately changed to introduce simple errors so that test cases can be validated to determine if they can detect the errors. The goal of mutation testing was to reduce complex program errors by preventing the related simple errors. Test cases are executed against the mutant code to determine if one fails, detects the error and ensures the program is correct. One major issue with this type of testing was it became intensive computationally to generate and test all possible mutations for complex programs.
