Toward Prebiotic Chemistry On Titan: Impact Experiments On Organic Haze Particles, Ben K.D. Pearce, Sarah M. Hörst, Christopher J. Cline, Mark J. Cintala, Chao He, Joshua A. Sebree, Shannon M. Mackenzie, R. Terik Daly, Alexandra J. Pontefract, Cara Pesciotta

Faculty Publications

Impacts are critical to producing the aqueous environments necessary to stimulate prebiotic chemistry on Titan’s surface. Furthermore, organic hazes resting on the surface are a likely feedstock of biomolecules. In this work, we conduct impact experiments on laboratory-produced organic haze particles and haze/sand mixtures and analyze these samples for life’s building blocks. Samples of unshocked haze and sand particles are also analyzed to determine the change in biomolecule concentrations and distributions from shocking. Across all samples, we detect seven nucleobases, nine proteinogenic amino acids, and five other biomolecules (e.g., urea) using a blank subtraction procedure to eliminate signals due to …

Global Change Impacts On Indigenous Sustainability In Sakha Republic: A Synthesis Of Knowledge, Stanislav Saas Ksenofontov, Andrey N. Petrov

Faculty Publications

Indigenous understanding of sustainability is embedded in close relations to land and environment, Indigenous Knowledge systems, Indigenous epistemologies and ontologies, and Indigenous languages. However, the sustainability of Indigenous peoples’ livelihoods is significantly affected by various global change drivers. In the Arctic, Indigenous peoples’ livelihoods are impacted by environmental, social, and cultural changes, including climate change, environmental pollution, economic processes, and resource extraction. This paper aims to review and synthesize recent academic and gray literature on the sustainability of Indigenous communities in Sakha Republic, Northeast Siberia, Russia in the face of global change with a particular focus on land- and water-based …

The effects of climate change depend on specific local circumstances, posing a challenge for worldwide research to comprehensively encompass the diverse impacts on various local social-ecological systems. Here we use a place-specific but cross-culturally comparable protocol to document climate change indicators and impacts as locally experienced and analyze their distribution. We collected first-hand data in 48 sites inhabited by Indigenous Peoples and local communities and covering all climate zones and nature-dependent livelihoods. We documented 1,661 site-agreed reports of change corresponding to 369 indicators. Reports of change vary according to climate zone and livelihood activity. We provide compelling evidence that climate …

Methods: We assessed the outcomes of the COVID-19 pandemic in Arctic sub-regions using three key epidemiological variables: confirmed cases, confirmed deaths, and case fatality ratio (CFR), along with vaccination rates to evaluate the effectiveness of the early vaccination campaign on the later dynamics of COVID-19 outcomes in these regions. Results: From February 2020 to February 2023, the Arctic …

Estimating The Cholesterol Affinity Of Integral Membrane Proteins From Experimental Data, Theodore L. Steck, S. M. Ali Tabei, Yvonne Lange

Faculty Publications

The cholesterol affinities of many integral plasma membrane proteins have been estimated by molecular computation. However, these values lack experimental confirmation. We therefore developed a simple mathematical model to extract sterol affinity constants and stoichiometries from published isotherms for the dependence of the activity of such proteins on the membrane cholesterol concentration. The binding curves for these proteins are sigmoidal, with strongly lagged thresholds attributable to competition for the cholesterol by bilayer phospholipids. The model provided isotherms that matched the experimental data using published values for the sterol association constants and stoichiometries of the phospholipids. Three oligomeric transporters were found …

The Effect Of Gratitude Journaling On Counselor Stress, Emily Kause

Graduate Research Papers

Stress and burnout are significant problems among those in helping professions, such as school counselors. High demands, time limitations, and vicarious trauma all contribute to the seemingly ever-rising levels of stress these individuals experience. It is critical for counselors to find strategies to lower their stress levels in order to prevent burnout, compassion fatigue, and the negative physical and mental health impacts of prolonged stress.

UNI Proud Documents

This project aims to provide the future of queer activists of this campus a better picture of the roots of activism on this campus. I think of this project as my own personal version of The Celluloid Closet, but instead of old movies it's old Northern Iowan articles. There has always been resistance at UNI, and this document hopes to show that resistance. It is however by no means complete, as often resistance has to occur in the shadows. What this work is hours and hours of searching the archives of The Northern Iowan, for those brief snapshots …

How Pizza And Stickers Drove My Kids To Read And Kept Them Reading, Tiya Montaño

Graduate Research Papers

Walk into any English/Language Arts (ELA) classroom across the country and you will find books on bookshelves, students on computers or cellphones, and a teacher struggling to garner the attention of their students long enough to make it through the short story, poem, or novel they are reading. This has become an all too familiar image that ELA teachers struggle with. Why won’t the students engage? Are the readings too difficult? Are the readings too boring? Am I teaching them all wrong? All these questions and more fly through our brains as they work towards trying to get the students …

Teachers Do It All: A Cluster-Based Analysis Of Abbott Elementary, Peter Heryla

Iowa Journal of Communication

This study employs rhetorical criticism to analyze the television sitcom Abbott Elementary (2021). Through close examination of the episodes “Pilot,” “Development Day,” and “Egg Drop,” this analysis aims to uncover key ideas about the multifaceted roles and responsibilities educators are required to assume outside of their main job as “teacher.” Utilizing cluster criticism, the study shows that being a teacher is about more than educating, and that teachers are motivated by common themes when they act outside of their role. The study also focuses on the mediated representation of teachers and the harmful demographic tropes that have historically characterized them, …

The Future Of Mediation: Mcluhanisms For The Quantum Era, Erik Gustafson

Iowa Journal of Communication

The 21st century has been characterized as a time of expansive and rapid technological change, particularly regarding the internet, digital technologies, and now artificial intelligence. Both scholarly and popular conversations have rushed to make sense of the technological phenomenon as they occur. Now, the “second quantum revolution” and the race for “quantum supremacy” threaten to push technological knowledge and applications even further from public understanding. As such, the present article sought to provide a host of theoretical and practical tools that may aid the public and scholars alike in understanding and combatting the overwhelming features of technology that may come …

Modeling Phosphorus Loading Dynamics In Milford Creek Watershed: With Comparison To A Consent Decree Tmdl, Olivia Calvin

Dissertations and Theses @ UNI

In 1998 Milford Creek, located in northwest Iowa, USA, was included on Iowa’s Impaired Waters List due to its inability to support aquatic life and excessive algal growth that was attributed to an overabundance of phosphorus within the body. In 2001 there was a lawsuit filed against the U.S. EPA regarding the status of Iowa’s Total Daily Maximum Load (TMDL) program. The lawsuit resulted in a consent decree that required the Iowa Department of Natural Resources (IDNR) to develop a TMDL for all bodies of water on Iowa’s 1998 impaired waters list by December 15, 2009, this list included Milford …

Positioning Paperback Books As Americana: Cultural And Historical Impacts Of The Wadle Pocket Book Collection, Jake Volk

Dissertations and Theses @ UNI

The first book in the form of a codex was bound around 300 BCE, but the earliest material used to record writing appeared around 3000 BCE. From these documents recording proto-writing of human history, people have sought to analyze and preserve writing, which continues as a contemporary work of scholars across multiple disciplines to form the field of the history of the book. As the book changed physical form from illuminated manuscripts on vellum to cheaply produced, paperback books, which appeared in the early 1800s, historians have documented these changes; however, more analysis is needed to categorize and interpret how …

Teacher Use Of Rubrics To Assess Claim, Evidence And Reasonings In The High School Science Classroom, Brianna Finnegan

Dissertations and Theses @ UNI

This qualitative study examines how high school science teachers in an eastern Iowa high school utilize rubrics to assess students’ claims, evidence, and reasoning (CER) in the science classroom. The research investigates the methodology teachers employ in assessing student proficiency using their own rubrics they have created. Data were collected through think-aloud interviews with participating teachers as they evaluated and scored CER examples. Analysis of interview data involved inductive coding to identify common themes and categories, shedding light on teacher’s scoring practices, rubric construction, and perceptions of student proficiency and rubric validity.

Findings reveal that teachers often weigh evidence and …
