Reconnecting With The Truth: Conspiracies, Perspective Taking, And Misinformation, Scott Sellnow-Richmond, Mili Pinski

Discourse: The Journal of the SCASD

“I’ve done my research.” Misinformation has become a prevalent topic in communication courses, particularly those focused on argumentation, public speaking, or even interpersonal and family communication. Students thus benefit from adapting public speaking-focused assignments to illuminate how to understand - and thus combat- disinformation in their own lives. This assignment works toward this goal in two stages, allowing students to argue not just against misinformation and conspiracies, but also to argue for them as an act of empathy and understanding. The applied nature of this exercise also empowers instructors with a way to concretely address this issue in the classroom. …

Differentiating Between Irony And Sarcasm: An Illustration Of Sarcasm’S Negative Impact On Audiences, Brent Kice

Discourse: The Journal of the SCASD

The following in-class activity helps students differentiate between ironic and sarcastic messages. In turn, students will recognize the negative impact of sarcastic messaging identified by Dynel (2013) and Averbeck (2013) in an effort for students to improve their own messages when attempting to persuade audiences.

“People Don’T Always Show Up The Way You Want Them To”: Utilizing The Hunger Games To Differentiate Between Persuasion, Coercion, Propaganda, And Manipulation, Nancy Bressler

Discourse: The Journal of the SCASD

The ability to define and conceptualize persuasion and its nuances without engaging in coercion, propaganda, and/or manipulation can be difficult for students at first. This activity centralizes the fine points among these persuasive concepts. Students also recognize the role of their audience in the persuasive messages that they create. Rather than only having a conversation about the common characteristics of these terms and how they differ, students can observe them within the fictional movie The Hunger Games: Mockingjay Part 1 (Lawrence, 2014). After discussing these ideas with their classmates, students then apply what they have learned by creating persuasive messages …

“Number Of Nonverbal Delivery Techniques”: Innovative Approaches To Gestures, Movement, And Vocal Delivery, Nancy Bressler

Discourse: The Journal of the SCASD

Through this activity, students consider to what extent gestures, movement, and vocal inflection affect a speech. Using the same speech content as the rest of their group, each student is provided a prompt requiring them to adapt their speech delivery differently. Through these differences, students can better understand how to incorporate nonverbal speech delivery that is natural, balanced, communicates emotion, and effectively communicates the message of the speech. Students discover the importance of nonverbal delivery while using an entertaining speech they may have seen in a television show. Overall, students learn how planned versus natural speech delivery can alter nonverbal …

Listen Up!: Measuring And Mitigating College Students’ Most Commonly-Reported Listening Challenges, Karla Hunter, Erin Lionberger, Ashley Phillips, Kaitlyn Luebbert, Andrea N. Briggs

Discourse: The Journal of the SCASD

This study updates the existing literature on listening education in two ways: 1) by providing an assessment of an effective listening education intervention and 2) by identifying what college students' self-assessment and reflection revealed as their most common barriers to listening and the actions that helped mitigate those challenges. Through content analysis, five graduate student coders analyzed six consecutive pre-Covid-19 semesters of student submissions to a Listening Log Self-Assessment assignment in an online interpersonal communication course (n = 186). This experiential activity was designed to motivate students' metacognitions to elicit accurate self-appraisals based on reflections of students' current listening encounters …

Analysis Of Per Capita Contributions From A Spatial Model Provides Strategies For Controlling Spread Of Invasive Carp, Donald R. Schoolmaster Jr., Alison A. Coulter, Jahn L. Kallis, Donald C. Glover, John M. Dettmers, Richard A. Erickson

Natural Resource Management Faculty Publications

Metapopulation models may be applied to inform natural resource management to guide actions targeted at location-specific subpopulations. Model insights frequently help to understand which subpopulations to target and highlight the importance of connections among subpopulations. For example, managers often treat aquatic invasive species populations as discrete populations due to hydrological (e.g., lakes, pools formed by dams) or jurisdictional boundaries (e.g., river segments by country or jurisdictional units such as states or provinces). However, aquatic invasive species often have high rates of dispersion and migration among heterogenous locations, which complicates traditional metapopulation models and may not conform to management boundaries. Controlling …

Efficacy Of A Typical Clean-In-Place Protocol Against In Vitro Membrane Biofilms, Diwakar Singh, Sanjeev Anand

Dairy Science and Food Science Faculty Publications: 2022 to Present

This study evaluates the effectiveness of a typical clean-in-place (CIP) protocol against in vitro biofilms on whey reverse osmosis (RO) membranes developed under static condition. Bacterial isolates obtained from RO membrane biofilms were used to develop single and multispecies biofilms under laboratory conditions. A typical commercial CIP protocol was tested against the 24-h-old biofilms, and included 6 sequential treatment steps based on alkali, surfactant, acid, enzyme, a second surfactant, and a sanitizer treatment step. Experiments were conducted in 4 replicates and the data were statistically analyzed. The results revealed a variation in the resistance of mixed-species biofilms against the individual …

Community-Level Phylogenetic Diversity Does Not Differ Between Rare And Common Lineages Across Tallgrass Prairies In The Northern Great Plains, Sarah A. Herzog, Maribeth Latvis

Native Plant Focused Publications

Niche differentiation has served as one explanation for species coexistence, and phylogenetic relatedness provides a means to approximate how ecologically similar species are to each other. To explore the contribution of rare species to community phylogenetic diversity, we sampled 21 plant communities across the Prairie Coteau ecoregion, an area of high conservation concern. We used breakpoint analysis through the iterative addition of less abundant species to the phylogenetic tree for each community to assess the contribution of rare species to community phylogenetic diversity. We also quantify the phylogenetic signal of abundance using Blomberg's K statistic and calculated the phylogenetic similarity …

Viewing Animal Migration Through A Social Lens, Ellen O. Aikens, Iris D. Bontekoe, Lara Blumenstiel, Anna Schlicksupp, Andrea Flick

Natural Resource Management Faculty Publications

Evidence of social learning is growing across the animal kingdom. Researchers have long hypothesized that social interactions play a key role in many animal migrations, but strong empirical support is scarce except in a few unique systems and species. In this review, we aim to catalyze advances in the study of social migrations by synthesizing research across disciplines and providing a framework for understanding when, how, and why social influences shape the decisions animals make during migration. Integrating research across the fields of social learning and migration ecology will advance our understanding of the complex behavioral phenomena of animal migration …

Ai-Enabled Droplet Detection And Tracking For Agricultural Spraying Systems, Praneel Acharya, Travis A. Burgers, Doang Nguyen

Mechanical Engineering Faculty Publications

his work leverages recent advancements in com- puter vision and deep learning to detect and track the motion of droplets captured by a camera. While classical computer vision techniques have been employed for detection and tracking, those approaches have limitations and are not trivially extended to droplets. We approach the problems of droplet detection and tracking through a data-driven framework, in which an annotated database of droplet images is built and object detection and tracking models are trained on this database. The accuracy of the model is evaluated and the whole process is discussed. At this point, droplet geometric properties …

Precipitation And Not Cover Crop Composition Influenced Corn Economic Optimal N Rate And Yield, Hunter Bielenberg, Jason D. Clark, Debankur Sanyal, Johnathon Wolthuizen, David Karki, Amin Rahhal

Agronomy, Horticulture and Plant Science Faculty Publications

The effects of single species cover crops on corn (Zea mays L.) N requirement and grain yield are well studied throughout the U.S. Midwest. However, comparing cover crop mixes that include different compositions of grass and broadleaf species is limited. Fourteen corn N response experiments were conducted in South Dakota from 2018 to 2021. Fall cover crops planted after small grain harvest were mixtures of dominantly grasses, broadleaves, a 50/50 grass/broadleaf mixture, and a no cover crop control. Compared to the control, including a cover crop led to no differences in economic optimal N rate (EONR) and yield at …

A Comparison Of Mini-Flotac And Mcmaster Techniques, Overdispersion And Prevalence Of Parasites In Naturally Infected North American Bison (Bison Bison) In The Usa, Wiliam L. Johnson, Samantha Reynolds, Colton L. Adkins, Bradly Wehus-Tow, Jameson R. Brennan, Catherine B. Krus, Danielle Buttke, Jeff M. Martin, Jeba R.J. Jesudoss Chelladurai

Natural Resource Management Faculty Publications

Several quantitative diagnostic techniques are available to estimate gastrointestinal parasite counts in the feces of ruminants. Comparing egg and oocyst magnitudes in naturally infected samples has been a recommended approach to rank fecal techniques. In this study, we compared the Mini-FLOTAC (sensitivity of 5 eggs per gram (EPG)/oocysts per gram (OPG)) and different averaged replicates of the modified McMaster techniques (sensitivity of 33.33 EPG/OPG) in 387 fecal samples from 10 herds of naturally infected North American bison in the Central Great Plains region of the USA. Both techniques were performed with fecal slurries homogenized in a fill-FLOTAC device. In the …

Industrial Energy Development Decouples Ungulate Migration From The Green Wave, Ellen O. Aikens, Teal B. Wyckoff, Hall Sawyer, Matthew J. Kauffman

Natural Resource Management Faculty Publications

The ability to freely move across the landscape to track the emergence of nutritious spring green-up (termed ‘green-wave surfing’) is key to the foraging strategy of migratory ungulates. Across the vast landscapes traversed by many migratory herds, habitats are being altered by development with unknown consequences for surfing. Using a unique long-term tracking dataset, we found that when energy development occurs within mule deer (Odocoileus hemionus) migration corridors, migrating animals become decoupled from the green wave. During the early phases of a coalbed natural gas development, deer synchronized their movements with peak green-up. But faced with increasing disturbance …

Auxin-Based Herbicide Program For Weed Control In Auxin Resistant Soybean, Joy Amajioyi, Thandiwe Nleya, Graig Reicks, Janet Moriles- Miller, David Clay, Sharon Clay

Agronomy, Horticulture and Plant Science Faculty Publications

Soybean [Glycine max (L.) Merr.] cultivars resistant to synthetic auxin herbicides have provided another mode of action for the postemergence broadleaf weed control. This field study was conducted at three South Dakota locations [Northeast, NERF; east-central, ARF; and Southeast, SERF) in 2019 and two locations (ARF and SERF) in 2020. The Enlist E3 and Roundup Ready 2 Xtend cultivars were planted at three dates (early, mid-, and late season) to examine weed control, agronomic characteristics, nodulation, and yield. Preemergence (PRE) treatment was flumioxazin + metribuzin + S-metolachlor + glyphosate + pendimethalin. Two postemergence (POST) treatments, based on cultivar, were compared …

Why Are Some Plant Species Missing From Restorations? A Diagnostic Tool For Temperate Grassland Ecosystems, Marcello De Vitis, Kayri Havens, Rebecca S. Barak, Louise Egerton-Warburton, Adrienne R.

Foxx, Kyndall Hadley, Jim Jabcon, Joan O’Shaughnessey, Sai Ramakrishna, David Sollenberger, Sophie Taddeo, Rafael Urbina-Casanova, Chris Woolridge, Lan Xu, Jacob Zeldin, Andrea T. Kramer

Natural Resource Management Faculty Publications

The U.N. Decade on Ecosystem Restoration aims to accelerate actions to prevent, halt, and reverse the degradation of ecosystems, and re-establish ecosystem functioning and species diversity. The practice of ecological restoration has made great progress in recent decades, as has recognition of the importance of species diversity to maintaining the long-term stability and functioning of restored ecosystems. Restorations may also focus on specific species to fulfill needed functions, such as supporting dependent wildlife or mitigating extinction risk. Yet even in the most carefully planned and managed restoration, target species may fail to germinate, establish, or persist. To support the successful …

Use Of Micellar Casein Concentrate And Milk Protein Concentrate Treated With Transglutaminase In Imitation Cheese Products—Unmelted Texture, Prafulla Salunke, Chenchaiah Marella, J. K. Amamcharla, K. Muthukumarappan, Lloyd Metzger

Dairy Science and Food Science Faculty Publications: 2022 to Present

The amount of intact casein provided by dairy ingredients is a critical parameter in dairy-based imitation mozzarella cheese (IMC) formulation because it has a significant effect on unmelted textural parameters such as hardness. From a functionality perspective, rennet casein (RCN) is the preferred ingredient. Milk protein concentrate (MPC) and micellar casein concentrate (MCC) cannot provide the required functionality due to the higher steric stability of casein micelle. However, the use of transglutaminase (TGase) has the potential to modify the surface properties of MPC and MCC and may improve their functionality in IMC. The objective of this study was to determine …
