Simulations Of Differential Reflectivity Columns In Quasi-Linear Convective Systems, Devon Jacob Healey

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Much research over the past decade has revealed that dual-polarization radar is a powerful tool in furthering our understanding of severe storm dynamics and subsequently improving warning strategies for these hazardous events. However, there are currently very few studies examining a particularly prolific severe convective storm mode with dual-polarization radar: quasi-linear convective systems (QLCSs). These storms can occur in any season of the year throughout most of the contiguous United States and can have immense societal impacts. Warning for the hazards produced by QLCSs is currently a significant operational challenge, therefore, research is needed to see if applying dual-polarization radar …

Nebraska Balanced Mix Design - Phase Ii, Farzad Yazdipanah, Mahdieh Khedmati, Jamilla Teixeira, Hamzeh Haghshenas

Nebraska Department of Transportation: Research Reports

Experiential Learning In Lecture Settings For Ides 200: Programs, Codes & Standards, Emily Cerny

UNL Faculty Course Portfolios

In traditional lecture settings, students take notes from a lecturer’s recitations and have minimal interaction with each other and the world around them. For IDES 200: Programs, Codes & Standards, a key aspect of learning is for students to understand the connections between the concepts learned in class and the built environment. To increase this connection and get students thinking in different manners, experiential learning methodologies were introduced through in-class exercises and within the course assignments alongside typical lectures and lecture comprehension quizzes. By surveying students’ perceptions of assignments and course activities, the goal of this course portfolio is to …

Advancing Butterfly Systematics Through Genomic Analysis, Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

Within the framework of an ongoing comparative genomic study of global butterfly diversity, we construct phylogenetic trees combining all protein-coding genes assembled from the whole genome shotgun data. When viewed in the context of current taxonomy and phenotypic knowledge, the genome-wide phylogeny points to further advances in butterfly systematics, which are presented here. We assign major clades with comparable levels of genetic divergence to the same taxonomic rank and apply criteria involving relative population divergence and gene flow to define species boundaries. As a result, one genus, 13 subgenera, 62 species, and five subspecies are proposed as new (type species …

“Honey, Life Is Just A Classroom:” Using Taylor Swift As A Pedagogical Tool For College Composition, Liz Thomae

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

As educators, we confront the challenge of cultivating a deeper understanding of writing in an age obsessed with utilitarianism, instant gratification, and pragmatism. Students come into our classrooms inundated with these messages of utility and often find subjects within the humanities, especially first year writing, boring and unhelpful. Especially with the rise of generative artificial intelligence (AI) use in our classrooms and society at large, we as pedagogues have our work cut out for us. I propose a pedagogical approach that bridges students' interests with essential writing skills by integrating Taylor Swift's music into the composition classroom. Swift's evolution as …

Analyzing Florida’S Lgbtqia+ Censorship Laws And Their Anti-Democratic Attack On Education, Peyton Sibert

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

The past four years (2021-2024) have seen an increase in academic censorship laws and anti-LGTBQIA+ rhetoric across the United States. Florida, specifically, has established itself as a leader in discriminatory legislation. In this paper, the author analyzes four Florida laws: HB 1557, HB 1069, HB 7, and SB 266, along with the rise in book bans to consider both the pedagogical effects and negative impacts on the LGBTQIA+ community. These analyses will be juxtaposed with extant political rhetoric around these laws to expose a) the intent of the law b) the contradictions within and across laws and thereby c) the …

Benefits Of Informal Practical Experiences As A Central Teaching Method In A Literature Of Adolescents Course, Jillian Harpster

UNL Faculty Course Portfolios

This portfolio includes the course context and organizational format of a junior-level required course for pre-service secondary English teachers.

The Connection Between An Unequitable Distribution Of Care Responsibilities And A Widening Gender Nutrition Gap In Latin America, Alexis Nicole Bodlak

Honors Program: Senior Projects (Public)

The notion of care refers to activities that satisfy the basic needs of existence and reproduction. Within rural communities, care work such as the production and preparation of food contributes to food security at the household level. Care work supports the paid workforce, allowing workers to focus on commercial productive activities that generate economic income in rural communities. Women perform 6.3 to 29.5 more hours per week than men in unpaid care work, reducing their time for income-generating activities and personal nutrition management. Affecting their economic independence and ability to access and consume nutritious food. Studies show that in food-insecure …

The Role Of Popular Culture In Decolonial Transformative Learning: A Racially Minoritized Adult Educator's Journey, Riyad Shahjahan

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

While a growing body of literature examines the role of popular culture in transformative learning, much of it centers on fostering transformative experiences among learners, rather than educators themselves. This paper addresses that gap by exploring how popular culture enhances transformative learning for racially minoritized adult educators. Drawing from my experiences as a graduate instructor at a predominantly white institution, I reflect on how engaging with popular cultural texts facilitated my own transformative learning within my teaching practice. Grounded in decolonial theory, which emphasizes the inclusion of Indigenous and marginalized knowledges while confronting contemporary colonial oppressions, my reflexive approach highlights …

What Is Climate Smart Agriculture? : A Standardized Framework For Assessing The Effectiveness Of Climate Smart Agriculture Systems And Practices, Olivia G. Messerges, Trenton W. Ford

RURALS: Review of Undergraduate Research in Agricultural and Life Sciences

The United States agricultural system is challenged with feeding a growing population, adapting to climate change, and minimizing environmental damage. In response to these challenges, the paradigm of climate-smart agriculture (CSA) was developed to describe practices that address these challenges as a comprehensive strategy to address climate change and increase food security.

Definitions of CSA vary, but surround three main pillars: increasing productivity, enhancing adaptation, and reducing emissions. However, no standardized framework exists to assess if practices or technologies identified as "climate-smart" produce the desired benefits. A standardized framework would enable producers, policymakers, and researchers to improve CSA implementation, policy …

Illustrating Identity: Ethel Reed’S Art Posters And Women's Claims To Public Space In Fin-De-Siècle Boston, Miranda R. Knofczynski

School of Art, Art History, and Design: Theses and Student Creative Work

Much scholarship has uncovered the history of women illustrators during the late nineteenth century. The rebuilding of these lost histories calls for research which theorizes women’s contributions to the burgeoning arts scene of the fin-de-siècle. This thesis will examine the posters Ethel Reed created for different companies during the height of the 1890s poster craze and discuss how she articulated women in public space in them. Reed’s art offers an aestheticized yet feminist visualization of women engaging in leisure activities such as exploring the city, reading, or attending the theatre. Many have described the women in her posters as merely …

Medusa's Metamorphosis: Art, Mythology, And The Changing Perception Of Female Power, Elizabeth Kehr

School of Art, Art History, and Design: Theses and Student Creative Work

The evolution of Medusa’s iconography in ancient Greek art mirrors societal and cultural transformations. As attitudes shifted in relation to gender roles, power relationships, and morality changed, so too did images of the Gorgon. Following the course of development of Medusa’s image allows one to discover details of the thoughts and struggles the ancient Greeks had with concepts of power, womanhood, and monstrosity and otherness. Previous art historical research on Medusa has largely examined her function and evolution of visual depictions from the Archaic monster to Classical ideal. Few, however, have explored how and why these changes may be indicative …
