Prevalence Of Emergency Management Across The Conservation Reserve Program And Effects Of Emergency Management On Field Vegetation, Gretchen Steffensmeier

Dissertations and Theses @ UNI

The Conservation Reserve Program (CRP) is an extensive government program established by the United States Department of Agriculture (USDA) in 1985 where farmers across the country agree to take land out of agricultural production and plant species to improve environmental health and quality in exchange for yearly rental payments. The main goals of CRP include re-establishing valuable land cover to improve water quality, preventing soil erosion, and reducing the loss of wildlife habitat. Currently, there are approximately 22 million acres enrolled across the country. The CRP is portrayed as a powerful tool that can be used to mitigate the impacts …

Teasing In Romantic Relationships: The Roles Of Attachment Dimensions, Relational Uncertainty, And Interpersonal Attraction, Nathan Miczo

Iowa Journal of Communication

Drawing upon DiCioccio’s interactionist model of teasing, this study examined positive and negative teasing in romantic relationships, with relational uncertainty and interpersonal attraction as mediators. Participants completed measures of teasing, attachment, relational uncertainty, and interpersonal attraction. Affectionate teasing was positively predicted by anxious attachment, physical attraction, and social attraction, and negatively predicted by avoidant attachment. Social attraction mediated the relationship between anxiety and affectionate teasing, while physical attraction and social attraction were mediators between avoidance and affectionate teasing. There were no significant results for relational uncertainty as a predictor or for aggressive teasing as an outcome.

Authenticity At Issue: Legislative Resistance To Gen Ai In Constituent Communication, Amy Mccoy

Iowa Journal of Communication

As legislators manage a fast-paced environment including an increasing number of legislative proposals, this research examines their perceptions around and understanding of generative artificial intelligence (Gen AI) and its potential applications related to constituent communications. This study explores how technological shifts in legislative communication, examined through New Media and Constructivist lenses, are interpreted and experienced by lawmakers. Through a mixed-methods approach using survey and interviews, this research provides insights on the contradiction of using Gen AI for legislative efficiency with concerns of how it may impact perceptions of authenticity and affect democratic engagement.

Student Affairs Professionals' Sensemaking Following Student Disclosures Of Mental Health Concerns, Andrea L. Meluch, Alison Doehring, Maria Hannah

Iowa Journal of Communication

Based on semi-structured interviews with 23 participants, this study explores how student affairs professionals in higher education make sense of the role-related and communication-related challenges that they face when students disclose mental health concerns. Study results indicated that participants construct their role as student affairs professionals as advocates and sources of support for students struggling with mental health. However, despite framing their role as “helpers” to students, participants noted that they must navigate mental health resources within and beyond their institution, manage constraints on their role, and grapple with external factors that inhibit students’ ability to receive mental health support. …

The purpose of this research was to better understand Flagstaff, Arizona (AZ) residents’ water knowledge, media uses, information sources, and water-related risk perceptions. After collecting survey responses from residents (n=476), results highlighted that most residents know their water supplier, but their risk perceptions varied as related to waterborne diseases and water scarcity. Particularly, participants felt more susceptible to water scarcity issues than waterborne diseases and felt that water scarcity was more severe than waterborne diseases. Further, when considering getting water-related information, many participants preferred receiving information via digital devices. Regarding social media use, participants held the strongest preference for receiving …

Toxic Sweetness And Abstinence: The Citationality Of Robert Lustig's Anti-Sugar Rhetoric, Tyler J. Snelling

Iowa Journal of Communication

Robert Lustig’s (2009) lecture on YouTube “Sugar: The Bitter Truth” animated a widespread conversation about whether sugar poisons bodies. Discourse following the lecture warrants analysis to gage how the meaning of the lecture transformed from a critique of food systems into individual actions. I argue that citationality of “Sugar: The Bitter Truth” fosters healthism by grounding sugar’s toxicity in scientific and affective reasoning that compels individual actions like abstinence from sugar. The pediatrician's lecture enabled the construction of a supposedly "moral eater" who removes sugar from consumption to avoid the poison's consequences. This paper offers tools for examining the spread …

Remembering July 36th: A Semiotic Analysis Of The Student-People's Revolutionary Graffiti, Jordan D. Smith

Iowa Journal of Communication

The use of graffiti as a tool for political solidarity has been universally documented in the academic lexicon. Using symbols of resilience, justice, disenfranchisement, and hope, graffiti is a unique phenomenon for visual rhetorical studies. The variety of artifacts spanning millennia document socio-political shifts, economic disparity, and messages of rebirth for systems in crisis. This study conducts a semiotic analysis of protest graffiti created during Bangladesh’s Student-People Uprising of July 2024 to explore how visual and linguistic signs construct messages of hope and solidarity. Using Ferdinand de Saussure’s (2021) semiotic framework, this research examines the symbolic and rhetorical elements present …

Moldy Whoppers And Vitamin Donuts: Health Halos In Food Advertisements, Debbie Danowski

Iowa Journal of Communication

Health Halos have been used in food advertisements since the late nineteenth and early twentieth centuries when the advent of mass-produced consumer goods took hold and manufactures began advertising their products. It wasn’t until nearly eight decades later, however, that theoretical framework specifically involving health halos was recognized in advertising research. Though subsequent research suggests the effectiveness of health halos in making unhealthy food appear healthier, there has been little, if any, attention given to identification of the health halos used in food advertising. This study aims to fill the gap by identifying two of the health halo techniques used …

Alexithymia: Toward An Experimental, Processual Affective Science With Effective Interventions, Olivier Luminet, Kristy A. Nielson

Psychology Faculty Research and Publications

Alexithymia is a multi-dimensional personality trait involving difficulty identifying feelings, difficulty describing feelings, and an externally oriented thinking style. Poor fantasy life is debated as another facet. For over 50 years, the alexithymia literature has examined how alexithymia-related disturbances in perceiving and expressing feelings contribute to mental and physical disorders. We review the current understanding of alexithymia—including its definition, etiology, measurement, and vulnerabilities for both mental and physical illness—and its treatment. We emphasize the importance of further experimental and processual affective science research that (a) emphasizes facet-level analysis toward an understanding of the nuanced bases of alexithymia effects on neural, …

Consumer Preferences For Low-Methane Beef: The Impact Of Pre-Purchase Information, Point-Of-Purchase Labels, And Increasing Prices, Kelly A. Davidson, Brandon R. Mcfadden, Sarah Meyer, John C. Bernard

Agricultural Economics and Agribusiness Faculty Publications and Presentations

Cattle production is estimated to be the largest methane (CH₄) emitter associated with consumer demand in the United States of America (U.S.). With a national commitment to reducing methane emissions by 30% before 2030, methane-reducing additives (MRAs) in livestock feed are being explored as a viable solution. This study investigated consumer preferences for low-methane ground beef produced using one of three MRAs with varying levels of methane mitigation: Aspagopsis taxiformis (seaweed), the organic compound 3-nitroxypropanol (3NOP), or a blend of essential oils (e.g. garlic extract and citrus). In a nationally representative survey, 3,009 respondents completed a labeled discrete …

Editorial: Midlife Brain Health: Understanding Brain Aging In Middle-Age And Effects Of Interventions To Prevent Neurodegeneration In Late Life, Junyeon Won, Marissa A. Gogniat, Takuya Kurazumi, Kristy A. Nielson

Psychology Faculty Research and Publications

With the rapid increase in the aging population, the prevalence of age-related neurodegenerative diseases such as Alzheimer's disease (AD) has risen significantly, affecting over 55 million people worldwide in 2023, with projections suggesting this number will exceed 78 million by 2030 (Better, 2023). While much research has been focused on understanding and treating AD in older adults, there is growing emphasis on early interventions to prevent its onset (Crous-Bou et al., 2017; Dohm-Hansen et al., 2024). In this regard, middle-age has gained recognition as a critical period for the development and prevention of AD (Ritchie et al., 2017). For example, …

The main findings, in the …

Professional Skills For Behavior Analysts: A Survey On The Proficiency And Importance Of Hard And Soft Skills, Landon S. Cowan, Tiffany Kodak

Psychology Faculty Research and Publications

Individuals seeking certification as board certified behavior analysts (BCBAs) require training in both hard and professional (soft) skills. Trainees seeking certification complete coursework, supervised fieldwork experience, and a BCBA exam that assesses mastery of hard skills. However, training and mastery of soft skills is not as defined. BCBAs are also expected to maintain these skills throughout their career. Previous research has shown that soft skills are viewed as important by clients and their caregivers but are not consistently demonstrated from those providing services. Research also suggests that BCBA trainees may not consistently receive training on soft skills. The current study …

Fault Box Modeling Of Dip Slip Faults: A Framework For Fault Box Design And Future Studies, Hailey Pressnell

Master's Theses

The behavior of soils during surface fault rupture is a serious concern in the planning and design of infrastructure that may be located within or near a fault zone. Challenges associated with developing mitigation measures for surface fault rupture include the uncertainty of fault rupture and the variability of fault behavior. Current analytical procedures define surface fault rupture according to the type of fault movement (strike slip, normal or reverse), the amount of displacement on the fault, and the mechanics of the material overlying the fault. The purpose of this thesis is to reconfirm analytical solutions and gain a better …

The Role Of Financial Literacy Education In Shaping Students’ Future Financial Decisions, Arianna Shornock

Honors Program Theses

This paper aims to explore the relationship between the effectiveness of financial literacy programs and their influence on students' future decision-making. In this study, survey data were collected from a random sample of young adults aged 18-25 years, primarily located in the Midwest region of the United States. This study suggests that students who took a financial literacy class are less likely to perform better on financial literacy topics and are less likely to have higher perceived confidence when making financial decisions, which contrasts with the existing evidence in the literature over financial literacy programs. Possible explanations for this deviation …

Analyzing The Safety Effects Of Edge Lane Roads For Motor Vehicle Users, John Yang

Master's Theses

This thesis builds upon a prior study that analyzed the safety effects of Edge Lane Roads (ELRs) within the U.S. context, addressing gaps related to collision, traffic volume, and speed data. An ELR is a roadway configuration that accommodates two-way automobile traffic within a single center lane while providing edge lanes for vulnerable road users (VRUs), i.e., bicyclists or pedestrians. Although the concept of a single shared lane for opposing traffic often raises safety concerns among the public, ELRs have demonstrated potential to control speeds, optimize roadway space, and improve traffic operations on low-volume roads.

To evaluate safety outcomes, this …

Designing An Affordable Motion Capture System For Multi-Robot Research And Education, Hojune Kim , '25

Senior Theses, Projects, and Awards

In this work, we propose a low-cost motion capture system for real-time tracking of multiple robots’ positions and orientations in indoor environments, specifically tailored for research and educational applications. Precise localization is essential for evaluating robotics algorithms such as decentralized multi-agent control, cooperative path planning, and collision avoidance. [1-3] However, commercial motion capture systems like Vicon and OptiTrack cost between $50,000 and $150,000, making them inaccessible for many smaller institutions, student clubs, and low-resource labs. To address this challenge, we developed an affordable alternative based on three ceiling-mounted 1080p USB cameras and AprilTags. Our system operates at 30 Hz and …

Progress Toward The Synthesis Of Pyridine-Containing Macrocycles Using Dynamic Alkyne And Olefin Metathesis, Stephen Kwas , '25

Senior Theses, Projects, and Awards

Tubular structures are ubiquitous in nature and possess functions ranging from the structural ones played by microtubules to transporting necessary ions across cell membranes by membrane proteins. In addition, the excellent electronic and structural properties of carbon nanotubes have made them of great interest to chemists. Yet, the functionalization of these nanotubes is hindered by unselective post-modification, often requiring harsh reaction conditions. As such, the assembly of macrocycles into nanotubular structures has been widely studied by chemists. One such way to make these materials is by using dynamic, reversible reactions to synthesize pyridine-containing macrocycles in high yields. Due to inherent …

Anxiety And Body-Focused Repetitive Behaviors: A Systematic Review And Meta-Analysis Of Comorbidity Rates And Symptom Associations, Kathryn E. Barber, Isabella F. Cram, Elyse C. Smith, Leila K. Capel, Ivar Snorrason, Douglas W. Woods

Psychology Faculty Research and Publications

Body-focused repetitive behavior (BFRB) disorders, including hair pulling disorder (trichotillomania [TTM]) and skin picking disorder (SPD), frequently co-occur with anxiety disorders, but reported comorbidity rates vary widely. Additionally, research on the relationship between anxiety and BFRB symptoms has yielded inconsistent findings. This meta-analysis and systematic review examined (1) the prevalence of comorbid anxiety disorders in individuals with BFRB disorders and (2) correlations between anxiety and BFRB symptom measures. The study protocol was pre-registered on PROSPERO. A systematic search of PsycInfo, PubMed, and Web of Science identified 119 studies (N=15,902) reporting anxiety prevalence rates in BFRB disorders and/or correlations between anxiety …
