Master of Arts in Digital Journalism
Digital communication tools have revolutionized corporate communications. These digital communication tools have come to enhance communication efficiency, but the reality for corporates in Kenya reveals a complex web of challenges not just in uptake but also in how these tools have made corporates leverage the digital platform to tell their own stories without the gatekeeping rigors of legacy media. The primary objective of this study was to explore how corporate communication functions have optimized the uptake of digital communication tools. The specific objectives of the study were to explore the uptake of digital communication tools in corporate organisations’ marketing communications, …
Factors Informing The Transition From Journalism To Corporate Communications, Muyanja Robert
Factors Informing The Transition From Journalism To Corporate Communications, Muyanja Robert
Master of Arts in Digital Journalism
This study investigated the shift of journalists to corporate communications, motivated by economic instability, professional obstacles, and the changing dynamics of the media sector. The study sought to evaluate the present work conditions of journalists, investigate the challenges encountered during their move to corporate communications, and analyse the motivations behind this career change. Decreasing earnings, unstable job security, and escalating workloads in conventional journalism have driven numerous journalists to pursue stability, professional advancement, and improved work-life balance in corporate positions. This transition presented problems, such as adapting to new professional standards, inter-role conflicts, and substantial emotional and identity upheavals. The …

The Legend Of Taylor Heinicke: An Autoethnography Of Unexpected, Passionate Fandom, Brendan O'Hallarn
Communication & Theatre Arts Faculty Publications
Passionate fandom is not a novel phenomenon in the field of sport. The fervor of fans builds stadiums and has allowed the sport industry to grow exponentially in the past few decades. Scholars have examined the passionate fan through many theoretical lenses, but comparatively little scholarship has looked at sport fandom fervor from inside. An autoethnographic examination of my unexpected journey as a fan of journeyman National Football League (NFL) quarterback Taylor Heinicke demonstrates how fandom can stir passions and create rituals in sport followers. A multimedia diary of Heinicke's unexpected ascension to starting quarterback of the Washington Commanders provides …

Master of Arts in Digital Journalism
Integrating AI in Kenyan digital media houses presents opportunities and challenges, underscoring the need for formal guidelines in newsrooms. This study examined the status of AI use guidelines in the editorial policies of Kenyan media houses, along with the challenges involved in formulating and implementing these guidelines. Semi-structured interviews served as the primary data collection method, conducted with editors and reporters from four purposively selected media houses: Nation Media Group (NMG), Kenyans.co.ke, Nairobileo.co.ke, and Sauce.co.ke, all based in Nairobi. A total of 14 journalists were interviewed. Additionally, editorial policies of the selected media houses were analysed to assess if AI …

Despite the growing interest in social justice activities, there is a lack of empirical evidence regarding their impact on various stakeholders, particularly social media users. We gathered longitudinal data from the NFL's @inspirechange X (former Twitter) account, a designated social justice communication handle, between August 2019 and March 2023. During this timeframe, the account garnered 20,967 comments (including original tweets and retweets) from 11,481 distinct users, but our analysis focused on 5851 comments deemed usable from 3632 unique users. Drawing on the social exchange theory, sentiment analysis, and thematic analysis, this study examines social media users' sentiments toward the NFL's …

Critical Environmental Communication Framework, Shumaila J. Bhatti, Srivi Ramasubramanian, Andrea Feldpausch-Parker, Bruno Takahashi, Silje Kristiansen
Media Studies - All Scholarship
This study develops a Critical Environmental Communication (CEC) framework to assess the landscape of Environmental Communication research and to what extent and in which ways critical and justice-oriented perspectives are included. The CEC framework consists of four interconnected themes: (a) Marginalized Ecocultural Identities, (b) Context and Scale, (c) Power and Agency, and (d) Justice, Equity, Diversity, Access, and Inclusion (JEDAI). Using this framework in a bibliometric analysis examining 1,297 Environmental Communication publications, we assess the occurrence of these themes in the scholarship. Our analysis found that Marginalized Ecocultural Identities, and Context and Scale were most frequently occurring, while Power and …

Media Studies - All Scholarship
As calls for media literacy in formal and informal learning spaces continue to grow, educators’ understanding of media literacies and their purposes remains complex. In 2021, the authors of this paper led a multi-methods research project on media literacy education in the United States, focusing on impact and equity. Findings showed that educators share a commitment to equity and justice but are unclear on how to incorporate them into their work. In response, our research team developed a field guide that maps out equitable media literacy practices for classrooms and communities. In this study, we detail the findings from 11 …

Comparing Funders' Altruism Versus Self-Interest: Leveraging The Context Of Crisis, Dan Liu, Guangzhi Shang, Cynthia Fan Yang
Journal of International Technology and Information Management
While reward-based crowdfunding has widespread popularity, the motivations driving funders, balancing self-interest and altruism, have remained puzzling. Prior research has been constrained by examination methods and produced mixed findings regarding the weight of altruism versus self-interest among funders. Our study takes a fresh perspective, delving into funder behavior amid a major crisis—the tumultuous backdrop of the COVID-19 pandemic. Our findings reveal that funders not only display an increased willingness to contribute but also significantly amplify their contributions, particularly to projects in crisis-affected regions, irrespective of external incentives like rewards. This underscores the prevalence of altruistic motives among funders in challenging …

Understanding The Determinants Of Blockchain Adoption: An Empirical Study, Amarpreet Kohli, Nihar Kumthekar, Piyush Shah, Rebecca Jauch
Journal of International Technology and Information Management
Blockchain technology (BT) has the potential to enhance security and robustness of transactions through a distributed ledger bookkeeping process. This study employs technology-organization-environment (TOE) framework and threat-rigidity theory (TRT) to examine whether perceived disruption caused by COVID-19 pandemic significantly impacted the adoption of BT, and inclination to adopt BT in the US. The COVID-19 pandemic provided a unique backdrop, as it affected businesses across all industries, sizes, and geographies. Results show a non-significant effect of perceived pandemic disruption on the current stage of BT adoption and intention to adopt BT. However, disruption readiness positively influences the current stage of BT …
A Content Analysis Of Doubt: How Latter-Day Saints Interact Online When One Of Their Own Seeks Answers, Leilani Naomi Mascio, Ronald Smith
A Content Analysis Of Doubt: How Latter-Day Saints Interact Online When One Of Their Own Seeks Answers, Leilani Naomi Mascio, Ronald Smith
Midwest Social Sciences Journal
This content analysis examines how members of the Church of Jesus Christ of Latter-day Saints (LDS) interact with doubting members in online forums, focusing on Facebook and Reddit. Analyzing 1,115 comments from four public posts (August 2024–January 2025), six emergent themes characterize these interactions: (1) normalizing doubt, (2) thought-terminating clichés, (3) bringing back to the fold, (4) hierarchical escalation, (5) attributing doubt to Satan, and (6) emotional reasoning. Findings reveal that LDS members overwhelmingly dominate these discussions, employing doctrinal language, personal narratives, and appeals to authority to reintegrate doubters. Notably, non-member interference was rare, suggesting moderated or self-selected engagement. The …
The Media Framing Of India’S Nuclear Weapons Discourse, Sitakanta Mishra, Hely Desai
The Media Framing Of India’S Nuclear Weapons Discourse, Sitakanta Mishra, Hely Desai
International Journal of Nuclear Security
The Indian media has had an immense role in framing public perceptions of nuclear weapons within the Indian subcontinent. Examining the largely nationalistic tone of news coverage helps analyze how the media has shaped India’s idea of its status as a nuclear weapon state. Examining the sociocultural discourse around the bomb, this paper analyzes the major influence that the Indian media has in information distribution and how that influence translates to the formation of the atomic attitudes of the masses. In situating the Indian media’s approach to nuclear weapons at large, this work studied the framing of domestic nuclear weapons …
Player 2 Has Entered The Culture War: Discourse, Ideology, And Narrative In Gamergate 2.0, Ashley C. Mccann
Player 2 Has Entered The Culture War: Discourse, Ideology, And Narrative In Gamergate 2.0, Ashley C. Mccann
Theses and Dissertations--Communication
My thesis addresses the ever-evolving landscape of Gamergate 2.0. Once a reactionary misogynistic harassment movement dedicated to attacking women in video games, the new iteration of Gamergate has evolved into an entirely new community. In its new iteration, Gamergate is even less ostensibly concerned with video games and more with reactionary content, mixing together nerd media, general pop culture, and right-wing politics. To study this community, I approach the Gamergate 2.0 community as an anti-fandom and reactionary affinity space. I argue that GamerGate 2.0 exists as its own powerful reactionary community that creates a worldview consisting of the desired destruction …

Everything Old Is Q Again: An Analysis Of The Resurgent #Pizzagate Myth In Social Media, Bond Benton, Daniela Peterka-Benton
Everything Old Is Q Again: An Analysis Of The Resurgent #Pizzagate Myth In Social Media, Bond Benton, Daniela Peterka-Benton
College of Communication and Media Scholarship and Creative Works
On November 28, 2023, X CEO Elon Musk posted a meme suggesting that the #pizzagate conspiracy had been suppressed by powerful forces complicit in the exploitation of children. The #pizzagate conspiracy presumed that elites had organized a ring serving pedophiles in the basement of a pizzeria in Washington D.C. The conspiracy was debunked in major news outlets with social media platforms such as Facebook banning such content, as well (BBC News). These efforts ultimately did not prevent #pizzagate from morphing into the QAnon conspiracy that would galvanize multiple extremist political movements (Bleakley). Specifically, however, #pizzagate as a discrete narrative was …

Digital Community Policing: Using Social Media To Engage Students And Enhance Campus Safety, Dathan C. Jackson
Digital Community Policing: Using Social Media To Engage Students And Enhance Campus Safety, Dathan C. Jackson
Dissertations of Practice
Campus police increasingly rely on social media to reach students, yet little is known about how these efforts influence trust, collaboration, and perceptions of safety. This qualitative case study examined how one public research university’s police department uses social media to support community-policing goals. Data came from student interviews, departmental policy analysis, and a review of social media content.
Findings showed three central patterns. First, top-down, compliance-oriented messaging limited connection and failed to meet students’ expectations for open, two-way communication. Second, consistent and authentic engagement, online and in person, helped build shared responsibility and strengthened trust in campus safety efforts. …

An Overview Of The Special Issue, Rachel Gibson, Trent Buskirk
Data Science Faculty Publications
[Introduction] Across the quantitative social sciences, researchers increasingly face significant challenges and opportunities prompted by the arrival of new sources of very rich, highly granular, and often unstructured digital data. While traditional methods such as surveys and content analysis tools remain indispensable for measuring individual attitudes, behaviors, demographic characteristics, and media messaging online, they often struggle to capture the complex multimodal information streams and metadata generated by social media platforms, mobile devices, sensors, and tracking applications. Collecting and analyzing these diverse new forms of content, dynamic moment-to-moment behaviors, and naturally occurring interactions has become a pressing and exciting research task-one …

An Integrated Machine Learning Approach For Identifying Emergency Rescue Messages On Social Media During Natural Disasters, Wael Khallouli, Jiang Li, Jingwei Huang, Ghaith Rabadi, Samuel Kovacic
School of Cybersecurity Faculty Publications
During large-scale disasters, emergency call centers are often overwhelmed by the large volume of rescue requests and calls for help. Consequently, people are turning to social media platforms to seek assistance. Rescue information posted on these platforms is extremely valuable for first responders to make informed rescue decisions. Therefore, the automatic identification of these requests from the vast amount of data posted on social media during crises is critical yet challenging. This work presents our ongoing research on applying deep learning techniques to extract actionable rescue information from social media during crises. We proposed a novel deep learning model that …

A New Deepfake Detection Method With No-Reference Image Quality Assessment To Resist Image Degradation, Jiajun Jiang, Wen-Chao Yang, Chung-Hao Chen, Timothy Young
Electrical & Computer Engineering Faculty Publications
Deepfake technology, which utilizes advanced AI models such as Generative Adversarial Networks (GANs), has led to the proliferation of highly convincing manipulated media, posing significant challenges for detection. Existing detection methods often struggle with the low-quality or compressed press, which is prevalent on social media platforms. This paper proposes a novel Deepfake detection framework that leverages No-Reference Image Quality Assessment (NRIQA) techniques, specifically, BRISQUE, NIQE, and PIQUE, to extract quality-related features from facial images. These features are then classified using a Support Vector Machine (SVM) with various kernel functions. We evaluate our method under both intra-dataset and cross-dataset settings. For …
Echo Chambers On The Left, Echo Chambers On The Right: How Socioideological Identity Emotion Shape Social Interaction Behavior On Social Media, Dean Carl Jackson
Echo Chambers On The Left, Echo Chambers On The Right: How Socioideological Identity Emotion Shape Social Interaction Behavior On Social Media, Dean Carl Jackson
Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–
This dissertation investigates how echo chambers emerge on social media by shifting the lens from aggregate patterns of information exposure to moment-by-moment, individual level interaction decisions between peers. I theorize that selective exposure online is not only about what content people consume or avoid, but also about selective social exposure—accepting, rejecting, or sharing with the sources of that content—guided by sociopolitical identity, ideological distance (ID), and discrete emotions. To test this, I employ two survey experiments using real tweets varying in ideological extremity and measure user’s likelihood to Block, Follow, Retweet, or reply, alongside self-reported emotional reactions and ID between …
