Experiments In Love: Longus’ Daphnis & Chloe And Henry De Vere Stacpoole’S The Blue Lagoon, L. Kirsten Day Nov 2024

Experiments In Love: Longus’ Daphnis & Chloe And Henry De Vere Stacpoole’S The Blue Lagoon, L. Kirsten Day

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

Despite a chronological gulf of nearly two thousand years, the second century C. E. Greek romance writer Longus and the early twentieth century Irish novelist Henry de Vere Stacpoole were prompted to produce their best works by a similar motive: an urge to explore the world, and particularly the phenomenon of love and desire, from a standpoint of complete innocence. Although the resulting novels, Daphnis & Chloe and The Blue Lagoon respectively, have no evident direct connection, they exhibit surprising similarities not only in plot, setting, and characterization, but also in the values, perspectives, and worldviews they advance. The striking …


Examining Adolescence And Agency In The Midst Of International Crisis: Pandemics, Pandemonium, And Zombie Young Adult Literature, T. Hunter Strickland Nov 2024

Examining Adolescence And Agency In The Midst Of International Crisis: Pandemics, Pandemonium, And Zombie Young Adult Literature, T. Hunter Strickland

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

The COVID-19 pandemic of 2020-22 brought an abundance of changes to secondary education as students transitioned across the country to virtual and hybrid learning contexts. Teachers flexed quickly and frequently to support the learning that students acquired in these new, digital spaces even as school, district, and state demands on teaching increased. The English/Language Arts classroom pivoted along with others as teachers sought out digital reading and writing resources for students to engage in. In the midst of a national crisis, a metaphorical monster that sought to destroy, much like Beowulf ’s dragon did, adolescent readers, despite the discourses of …


Mixedness Comes Of Age: Learning From Multiracial Portrayals In Young Adult Tv Series, Marc P. Johnston-Guerrero, Lisa Delacruz Combs Nov 2024

Mixedness Comes Of Age: Learning From Multiracial Portrayals In Young Adult Tv Series, Marc P. Johnston-Guerrero, Lisa Delacruz Combs

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

Representation in literature, popular culture, and media has been shown to influence identity development and belonging as exemplified in the enduring hashtag #RepresentationMatters. However, mixed race representation on television has received little attention in research and scholarship. Hence, this essay examines how multiracial characters are portrayed in coming of age and young adult storylines from four TV series (All American, Charmed, Trinkets, and Dear White Peoples) representing two different networks (Netflix and The CW). Through a close reading of dialogue within the context of larger story arcs, we identify and critique common tropes in order …


Embracing The Fiasco!: Roleplaying Games, Pedagogy And Student Success, Erik Stanley, Michelle Schmidt, David Sweeten Nov 2024

Embracing The Fiasco!: Roleplaying Games, Pedagogy And Student Success, Erik Stanley, Michelle Schmidt, David Sweeten

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

This article explores the relationship between games and pedagogy through the example of the roleplaying game Fiasco!. Fiasco! is a part of a growing genre of collaborative roleplaying games (RPGs) that have important applications in the university classroom. Fiasco! is an innovative game system that upends the traditional model of Game Master-led RPGs to create a collaborative environment for players to create their own stories. This paper explores how the unique model embedded within Fiasco! can be employed as a pedagogical tool for active student-led learning.

To showcase the pedagogical innovations of a game like Fiasco!, we present …

Peril And Promise: Student Experiences Of Virtual Reality And Implications For Inclusive Social Justice Pedagogy, Michelle Vannatta Nov 2024

Peril And Promise: Student Experiences Of Virtual Reality And Implications For Inclusive Social Justice Pedagogy, Michelle Vannatta

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

Virtual reality (VR) is a fast-evolving technology rapidly being integrated into education and training in multiple sectors of society. As the use of VR spreads, it is important to critically analyze both its role in effective pedagogies and how students experience it. Virtual reality has extraordinary promise for deeply engaging students, and it also poses particular challenges for equitable and effective teaching of diverse students. This paper discusses students’ responses to a VR exercise and examines some of the complexities VR presents around racial justice, gender equity, and economic fairness. Virtual reality technology may be less effective and less comfortable …

Conceptualizing Empathy And Prosocial Action: Teaching Film Within The Literature Classroom, Mayuri Deka

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

The experience of viewing a movie in the global era is multi-faceted. A viewer’s response to a cinematic experience as Carl Plantinga explains in Moving Viewers: American Film and the Spectator’s Experience is not only admiration for the aesthetics and techniques employed in the movie but also in the emotions aroused by the storyline. Audiences react to the story and characters presented with directed emotions by imagining either their mental lives and feelings or their situations. Empathy occurs within this framework of imagination where the audience engages with the story and character based on these directed emotions. The audience …

Visuality Of Race In Popular Culture: Teaching Racial Histories And Iconography In Media, Joni Boyd Acuff, Amelia M. Kraehe

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

The repetition of racist imagery from historical to contemporary popular culture is indicative of a lack of visual culture education among artists, designers, and other creative cultural producers working today. This paper addresses the dearth of resources for teaching visual codes and conventions of racial iconography that are recycled in popular media and contribute to the fabrication of racial differences, maintenance of racial hierarchies, and normalization of white supremacist ideology. Inspired by Critical Race Theory in art and visual culture education, the essay proposes teaching tactics and sites/sights that can support students in developing visual understandings of race in popular …


Queerly Cultivating Anti-Racist Feminist Pedagogy, Laurie Fuller Nov 2024

Queerly Cultivating Anti-Racist Feminist Pedagogy, Laurie Fuller

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

Queerly Cultivating Anti-Racist Feminist Pedagogy raises questions and analyzes classroom practices based on adrienne maree brown’s (2017) Emergent Strategy, a radical self-help manual for our current political climate that calls for a paradigm shift in organizing work. Black, mixed, queer, pansexual, feminist writer, pleasure activist, facilitator and sci-fi scholar, brown builds on a continuous tradition of women of color feminists resisting oppression to bring together science fiction and permaculture, biomimicry and organizing, pleasure and activism. She offers fresh perspectives on how to imagine liberation and provides dynamic ways to think about teaching and learning. Emergent Strategy provides principles to …

Using News To Start Class: How Small Daily Interactions Affect Larger Classroom Interactions, Laura M. Dumin

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

In 2013, I added an extra credit assignment to my freshmen composition classes encouraging students to bring in news stories each class period; this assignment was designed to encourage students to be more willing to participate in classroom discussions. We then spent the first few minutes of each class discussing the stories they brought. After using this assignment for a few years, I had anecdotal evidence to suggest that my students were generally more talkative in class after the first week or two of sharing news. These experiences made me want to see if I could measure some change or …


“I Am A Conversation”: Media Literacy, Queer Pedagogy, And Steven Universe In College Curriculum, Misty Thomas Nov 2024

“I Am A Conversation”: Media Literacy, Queer Pedagogy, And Steven Universe In College Curriculum, Misty Thomas

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

The recent cartoon show on Cartoon Network Steven Universe allows for the blending of both queer theory and media literacies to create a pedagogical space for students to investigate and analyze not only queerness, but also normative and non-normative identities. This show creates characters as well as relationships that both break with and subvert what would be considered traditional masculine and feminine identities. Additionally, Steven Universe also creates a space where sexuality and transgender bodies are represented. This paper demonstrates both the presence of queerness within the show and the pedagogical implications for using this piece of media within a …


Bad Girls: Agency, Revenge, And Redemption In Contemporary Drama, Courtney Watson Nov 2024

Bad Girls: Agency, Revenge, And Redemption In Contemporary Drama, Courtney Watson

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

Cultural movements including #TimesUp and #MeToo have contributed momentum to the demand for and development of smart, justified female criminal characters in contemporary television drama. These women are representations of shifting power dynamics, and they possess agency as they channel their desires and fury into success, redemption, and revenge. Building on works including Gillian Flynn’s Gone Girl and Netflix’s Orange is the New Black, dramas produced since 2016—including The Handmaid’s Tale, Ozark, and Killing Eve—have featured the rise of women who use rule-breaking, rebellion, and crime to enact positive change.


Nature Vs. Nurture In Albuquerque: What Breaking Bad And Better Call Saul Teach Us About How We Talk About Criminals, Max Romanowski Nov 2024

Nature Vs. Nurture In Albuquerque: What Breaking Bad And Better Call Saul Teach Us About How We Talk About Criminals, Max Romanowski

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

Breaking Bad and Better Call Saul focus on the criminal transformation of their two main characters, Walter White (Bryan Cranston) and Jimmy McGill (Bob Odenkirk). While quite similar on the surface, Walter and Jimmy’s narratives represent two different criminal transitions, evoking the classic nature vs nurture conversation. Both of these shows bring the conversation to the idea of inevitability. The nature vs. nurture argument is a popular one because it acts as a teaching tool for how we think and talk about criminal behavior. At first, it follows that since criminality was in Walter White’s nature the whole time, his …


We All Have Jobs Here: Teaching And Learning With Multiple Intelligences In The Walking Dead, Lizabeth Gartley Nov 2024

We All Have Jobs Here: Teaching And Learning With Multiple Intelligences In The Walking Dead, Lizabeth Gartley

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

With the rise of cultural studies, positivism and formalism fell out of favor. But in recent years, altered versions of these methodologies have been suggested as solutions to the deficiencies of the ideological approach dominating the field. Where the ideological approach looks at the content of texts to determine their meaning, the aesthetic approach adopted by media scholars in recent years returns to the close textual readings of formalism (while abandoning its assertion that meaning resides in the text alone). Similarly, where the ideological approach tends to use textual analysis devoid of sociological empiricism, the use of “big data” in …


More Than Simple Plagiarism: Ligotti, Pizzolatto, And True Detective’S Terrestrial Horror, Jonathan Elmore Nov 2024

More Than Simple Plagiarism: Ligotti, Pizzolatto, And True Detective’S Terrestrial Horror, Jonathan Elmore

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

Of course, True Detective is neither a philosopher’s bedtime story nor supernatural horror, and yet there remains a productive affinity between Ligotti’s work and the HBO series. Where Ligotti provides substantial portions of the hallmark character’s identity and dialogue, True Detective puts Ligotti’s thought experiment to far more practical uses than does Ligotti himself. By intertwining hurricanes and flooding alongside industry and pollution into the background and negative space of the setting, the series implicates the urgent material reality of climate change and environmental collapse into the setting: “all of this is going to be under water in thirty years” …


The Costs Of Ecosystem Disturbances, E. Wesley F. Peterson Nov 2024

The Costs Of Ecosystem Disturbances, E. Wesley F. Peterson

Cornhusker Economics

Presents an illustration of the interdependencies inherent in natural ecosystems. An ecosystem may be defined as: “… a single environment and every living (biotic) organism and non-living (abiotic) factor that is contained within it or characterizes it. An ecosystem embodies every aspect of a single habitat, including all interactions between its different elements” (Knapp 2020). In such interdependent systems, removal of one or more of the essential “elements” can severely disrupt the functioning of the system and such disruptions can give rise to negative impacts on the environment and human health and well-being.


Destructive Plasticity, “Surplus Of Consciousness,” And The “Monster” In True Detective, Courtney Patrick-Weber Nov 2024

Destructive Plasticity, “Surplus Of Consciousness,” And The “Monster” In True Detective, Courtney Patrick-Weber

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

The first season of HBO's cult hit True Detective introduced viewers to a southern gothic murder mystery that many will not easily forget. Since many of us focused primarily on the whodunit narrative, we may have missed the narrative of trauma simmering under the surface of the story. This narrative of trauma reveals a deeper layer to the story between Detective Rust Cohle and serial killer Errol Childress, one that also reveals our own fears regarding trauma in our lives. By applying first the nihilist philosophies of Peter Zapffe with Cohle and Catherine Malabou's concept on destructive plasticity in Childress, …


Reflections On Building A Popular Writing Course, Emily Howson, Chris Massenburg, Cecilia Shelton Nov 2024

Reflections On Building A Popular Writing Course, Emily Howson, Chris Massenburg, Cecilia Shelton

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

Composition pedagogy has typically employed traditional academic texts in the instruction of first-year writing courses. In this article, three first-year writing instructors reflect on their experiences employing popular culture artifacts in lieu of more traditional academic texts in writing classrooms at a small, private, historically black institution (HBCU). By retrospectively analyzing the intersections between theory and practice, the instructors’ autoethnographic reflections explore the utility of popular culture artifacts as tools for teaching and learning writing, with an emphasis on rhetorical knowledge and transfer. Though preliminary, their conclusions point to the potential of popular culture for integration into traditional best practices …


Girls, Guns, And Zombies: Five Dimensions Of Teaching And Learning In The Walking Dead, Anthony Neely Nov 2024

Girls, Guns, And Zombies: Five Dimensions Of Teaching And Learning In The Walking Dead, Anthony Neely

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

Rooted in sociocultural theory, this article utilizes a conceptual framework derived from Alexander, Schallert, and Reynolds’ four topographical dimensions of learning: who of learning, what of learning, where of learning, and when of learning. Situated learning (Lave and Wenger) is presented as a fifth dimension to address how learning occurs in communities of practice absent of formal schooling. Content analysis (Elo and Kyngass) is used to analyze a teaching and learning event from an episode of The Walking Dead based on the five topographical dimensions of learning listed above. Findings provide insights for pedagogical application for …

Protracted Maternal Malnutrition Induces Aberrant Changes In Maternal Uterine Artery Hemodynamics And The Metabolic Profiles Of The Dam And Neonate, Jennifer F. Thorson, Ligia D. Prezotto Nov 2024

Protracted Maternal Malnutrition Induces Aberrant Changes In Maternal Uterine Artery Hemodynamics And The Metabolic Profiles Of The Dam And Neonate, Jennifer F. Thorson, Ligia D. Prezotto

Department of Animal Science: Faculty Publications

Malnutritional stress during gestation is a well-established driver of metabolic disfunction in offspring. Extended exposure to malnutrition requires metabolic plasticity as the animal shifts toward a catabolic state. In this paper we demonstrate the influence of malnutrition throughout gestation on uterine artery hemodynamics and the metabolism of the dam and neonate. We hypothesized that gestational malnutrition reduces blood flow of the maternal uterine artery and regulates the metabolic profile of the dam and offspring. Further, the combination of these factors consequently influences the concentration of metabolites in the cerebrospinal fluid of the neonate at birth. To test our hypotheses, pregnant …

Designing A Decision-Support Tool For Fertilizer Recommendations In Oil Palm Smallholders, Rana Farrasati Nov 2024

Designing A Decision-Support Tool For Fertilizer Recommendations In Oil Palm Smallholders, Rana Farrasati

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Oil palm (Elaeis guineensis Jacq.), originally from West Africa, now accounts for 42% of global vegetable oil production and mainly includes key regions cultivated in tropical regions of Southeast Asia, West Africa, South America, and Central America. Despite its economic significance, the oil palm industry faces challenges of stagnant yields and large yield gaps, particularly among independent smallholders. These issues often stem from inadequate nutrient management practices and limited agronomic knowledge. Our objective was to quantify nutrient requirements for mature oil palm plantations as a basis to design a decision support tool (DST) for fertilizer recommendations. To do so, …


Bio-Based Sprayable Mulch For Weed Control In Row Crop Systems, Camila Chiaranda Rodrigues Nov 2024

Bio-Based Sprayable Mulch For Weed Control In Row Crop Systems, Camila Chiaranda Rodrigues

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Improving current crop productivity levels requires transformative advancements in management, engineering, and science. One of the main challenges is the increasing difficulty of weed management due to herbicide-resistant weeds. There is a growing need for alternative weed management methods to reduce pesticide use and improve environmental safety. An emerging technology that is being developed is spray-on films which could help address these challenges. Spray-on films are liquid solutions that after spraying on the soil will dry and form a physical barrier. The overall objective of this research was to evaluate the effectiveness of a chicken feather bio-based sprayable mulch film …


Assessing The Above- And Belowground Productivity Of Fall-Planted Cover Crop Cultivars In Nebraska's Diverse Ecoregions, Bridget Mckinley Nov 2024

Assessing The Above- And Belowground Productivity Of Fall-Planted Cover Crop Cultivars In Nebraska's Diverse Ecoregions, Bridget Mckinley

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Cover crops (CC) provide essential ecosystem services including soil conservation, nutrient cycling, and weed suppression, through the accumulation of aboveground (AGB) and belowground (BGB) biomass. While AGB has been widely studied, BGB contributions, particularly root development and distribution, remain less understood. This study evaluated fall-planted CC across three Nebraska ecoregions, assessing AGB productivity, BGB biomass, and correlations between ground cover, plant height, and AGB.

Thirty treatments, including grasses, legumes, brassicas, and mixtures, were evaluated over two fall growing seasons (2022–2023 and 2023–2024) at three UNL research centers in northeast, west central, and west Nebraska. AGB was highest at west site …
