Assessing The Threat Of Social Media To National Security: Information Operations In The 21st Century, Brendan M. Cullen

Senior Theses

The ubiquity of social media has enabled an unprecedented amount of personal data to be accessible to various entities. Social media platforms leverage this data to optimize algorithmic recommendation systems, persuade users to engage, and promote monetization. The social media ecosystem’s business model demands continuous engagement and the relentless collection of user data to grow and scale. Not only is social media massively popular around the world, but it has integrated heavily into users’ daily lives. This integration is driven by social platforms’ deliberate architectures and affordances. The intentionality of social media can be exploited by state and non-state actors …

Evaluation Of Different Machine Learning, Deep Learning And Text Processing Techniques For Hate Speech Detection, Nabil Shawkat

MSU Graduate Theses

Social media has become a domain that involves a lot of hate speech. Some users feel entitled to engage in abusive conversations by sending abusive messages, tweets, or photos to other users. It is critical to detect hate speech and prevent innocent users from becoming victims. In this study, I explore the effectiveness and performance of various machine learning methods employing text processing techniques to create a robust system for hate speech identification. I assess the performance of Naïve Bayes, Support Vector Machines, Decision Trees, Random Forests, Logistic Regression, and K Nearest Neighbors using three distinct datasets sourced from social …

Information Justice: The Histories And Futures Of Technology And Social Categories, Patrick Sweeney

Dissertations, Theses, and Capstone Projects

My dissertation examines two controversies related to emergent uses of information from social media in psychological research and application. It focuses on controversies surrounding studies of face-based gaydar and the use of psychographic targeting by Cambridge Analytica in the 2016 US presidential election. Each controversy is analyzed in a case study that explores the issues specific to that study in relation to broader patterns across contexts to identify emergent trends in the use of information from social media in psychological research. Qualitative Content Analysis is used to analyze extant texts relevant to each case. In each study, findings related to …

The Internet-Extended Mind: The Psychological Ramifications And Philosophical Implications Of Cognitive Offloading, Gloria Choi

Scripps Senior Theses

In this thesis, I explore the internet-extended mind through both philosophical and psychological lenses in order to investigate the questions “To what extent is the mind extended onto the internet and, more generally, outside our bodies?” and “How will an increasingly internet-extended brain change the ways in which humans communicate, remember, and behave?”. First, I introduce the idea of a mind that extends out into the world, instead of lying solely in the brain. Then, I outline existing research that introduces the challenges and implications of an internet-extended mind in an ever-changing internet landscape. Next, I discuss how the internet …

The Evolution Of Computational Propaganda: Trends, Threats, And Implications Now And In The Future, Holly Schnader

Senior Honors Projects, 2010-2019

Computational propaganda involves the use of selected narratives, social networks, and complex algorithms in order to develop and conduct influence operations (Woolley and Howard, 2017). In recent years the use of computational propaganda as an arm of cyberwarfare has increased in frequency. I aim to explore this topic to further understand the underlying forces behind the implementation of this tactic and then conduct a futures analysis to best determine how this topic will change over time. Additionally, I hope to gain insights on the implications of the current and potential future trends that computational propaganda has.

My preliminary assessment shows …

Networks Of Isolation: The Case Of Donald J. Trump, Facebook, And The Limits Of Social Movement Theory, Carol L. Stimmel

International Development, Community and Environment (IDCE)

The 2016 election that catapulted Donald J. Trump to the U.S. presidency has raised questions for how Facebook may have enabled the emergence and coalescence of a social movement among traditionally improbable voters. The research in this paper engages with contemporary social movement theory, assessing its adequacy for explaining the role of Facebook as a primary method for facilitating a social movement among the civically-alienated, who are the most unlikely of all Americans to join an organized collective for change. From a methodological perspective, the exploration takes up the case as a strategy of inquiry to explore social movement theory …

Reconceptualizing The Work Of A Content Provider For An Online Audience: A Case Study For How Pedagogical Strategies Can Provide Models Of Engagement For Producers Of Entertainment, Diane Cooke

English Theses & Dissertations

With the interconnectivity of the Internet, and the availability of affordable media compositional tools, the proliferation of online media continues to grow exponentially. However, each day is still comprised of a fixed 24 hours, with far fewer hours spent in active media consumption. Considering the global potential for content to be found (Moreville), discovered (Cormier) or spread (Jenkins), content providers are looking for ways to attract, cultivate and hopefully expand their audiences amid all this digital clutter. In the field of entertainment, this challenge is complicated when small content providers are not aligned with an online, curated network such as …

Empirical Analysis Of Socio-Cognitive Factors Affecting Security Behaviors And Practices Of Smartphone Users, Joseph P. Simpson

CCE Theses and Dissertations

The overall security posture of information systems (IS) depends on the behaviors of the IS users. Several studies have shown that users are the greatest vulnerability to IS security. The proliferation of smartphones is introducing an entirely new set of risks, threats, and vulnerabilities. Smartphone devices amplify this data exposure problem by enabling instantaneous transmission and storage of personally identifiable information (PII) by smartphone users, which is becoming a major security risk. Moreover, companies are also capitalizing on the availability and powerful computing capabilities of these smartphone devices and developing a bring-your-own-device (BYOD) program, which makes companies susceptible to divulgence …

Disrupting Infrastructure: Social Media And Accessing Digital Publics, Carolyn K. Grant

Open Access Theses

This thesis investigates infrastructural barriers to effecting change through social media participation. Though social media is said to hold "democratic potential" by enabling open access to the digital public sphere, in reality it is often still the most privileged voices that get heard. Even in success cases of the power of social media like the Arab Spring, situational contexts lead to particular infrastructural access points that are not universally transferable, and still tend to favor mainstream perspectives. Barriers to amplifying marginalized voices include inadequate systems for digital memory and sharing algorithms that promote the visibility of the already visible. These …

Geospatial Data Accessibility In Web 2.0 Environments, Sara Helen Mcnamee

Masters Theses

Geographically referenced data is becoming a robust source of information because the use of place-based relevance searching is being employed as a popular form of information access and dispersal. To address this trend, the researcher conducted a study on the usability of the USA National Phenology Network (http://www.usanpn.org/), engaging 6 volunteer participants structured usability test of the USANPN mapping application. The participants were asked to complete two tasks, and data was collected both during (in the form of a think aloud exercise) and after the test (in the form of an exit interview). From the data collected, the researcher aimed …
