Generalized Reference Targeting For Spacecraft, David Geller, David Woffinden, Collin York

Space Dynamics Laboratory Publications

For spaceflight programs to achieve some of the aggressive exploration initiatives such as visiting and landing on other celestial bodies, rendezvousing with other orbiting vehicles, and ultimately returning crew safely to Earth, an assortment of targeting algorithms to compute the necessary burns to strategically maneuver a spacecraft to a variety of destinations are required. Numerous examples exist, but rather than creating and implementing multiple targeting solutions, is it possible to have a general targeting model that can accommodate a variety of applications? Originally motivated for mission design and analysis purposes, this paper outlines a generalized reference targeting algorithm for spaceflight …

Analyzing The Portrayal Of The Atomic Bombs Dropped On Hiroshima And Nagasaki In Textbooks And Non-Profit Curriculum Sources, Kason Kendall

Teacher Education and Leadership Student Research

Some veteran history teachers I have met over the years have explained that early in their careers they were encouraged to teach from the textbook. One teacher indicated this has been the dominant mode of teaching for the large portion of her career (J. Baker, personal communication, July 11, 2023). This can be problematic if textbooks do not contain multiple perspectives of events. Keith Crawford and Stuart Foster (2007) write that nations often do not tell the full truth about themselves. U.S. History curriculum is often missing a complete and accurate representation of historical events (Anyon, 1979). Textbooks often support …

Using A Token Economy In A First-Grade Classroom To Increase On-Task Behavior, Ana Kesler, Emma Preston, Milad Najafichaghabouri, Kristen R. Rolf

Special Education and Rehabilitation Counseling Faculty Publications

Token economies are an adaptable intervention used effectively in many settings to improve behavior, including schools. When used in schools, students are often given a board or chart on which to collect tokens (i.e., small items or marks) for desired behavior(s). Tokens are then exchanged for students’ preferred rewards. This chapter presents a case study of token economies implemented with five students who were unresponsive to class-wide (Tier 1) strategies in a general education first-grade classroom. The intervention was designed and implemented by a paraeducator who worked collaboratively with the classroom teacher to select students, develop intervention procedures, collect and …

Evaluating Lethal Coyote Management In The Chicago Metropolitan Area Using A Conflict Recurrence Metric, Jeffrey T. Schultz, Scott Beckerman, Robert Erickson, Danielle Montgomery, Stewart W. Breck

Human–Wildlife Interactions

Human–coyote (Canis latrans) conflict in urban environments is prevalent in cities throughout the United States. Urban areas commonly use nonlethal techniques to mitigate coyote-caused conflicts but will also incorporate selective removal of individual coyotes when conflicts persist. However, little research has evaluated these management strategies. This study analyzed coyote removal efforts conducted in the Chicago Metropolitan Area from 2010 to 2020. To evaluate the management actions, we used “time without incidence”—the time elapsing from an initial conflict until either a subsequent conflict occurred in the same area, or when the data collection period ended—as an index of effectiveness. …

Use Of Scat Dna To Estimate Coyote Abundance On A Newly Colonized Barrier Island, Sonia M. Hernandez, Michael J. Yabsley, Sarah C. Webster, Elizabeth M. Kierepka, Rochelle R. Beasley, Carly L. Landa, Heather W. Barron, Kelly Sloan, Holly Milbrandt, James C. Beasley

Human–Wildlife Interactions

Coyotes (Canis latrans) have expanded in mainland eastern North America and are known to have successfully colonized numerous islands. However, there are scarce data on the densities of coyotes in these ecosystems, in which coyotes can have substantive negative impacts. Coyotes first colonized Sanibel Island, a barrier island off the western coast of Florida, USA, in 2011, and their presence has been linked to declines in several sensitive species. However, the population size of coyotes has only been estimated from anecdotal reports and camera traps. Our goal was to estimate the size of the coyote population on Sanibel …

Cost-Effective Strategies For Feral Swine Control: Exploring Trapping Equipment Cooperatives, Phil Kenkel, Riza Radmehr, Rodney Holcomb, Mckenzie Boyce

Human–Wildlife Interactions

Feral swine (Sus scrofa) in the United States have become a growing concern, with a population of ≥6 million and causing annual damages of ≥$1.5 billion USD. Because of their high reproductive capacity, effective control methods are crucial to reducing or slowing their population growth. While remotely monitored and triggered traps have proven to be an effective control strategy, the cost of sophisticated trapping equipment, which can cost ≥$7,000 USD, is often cost prohibitive for many landowners. Despite the pressing need to address the challenge of making effective feral swine control methods more affordable, there are few studies …

Factors Influencing The Discovery And Use Of Carrion By Vertebrate Scavengers From Human-Induced Mass-Mortality Events, Samantha J. Leivers, Michael J. Bodenchuk, Tyler A. Campbell, John M. Tomeček

Human–Wildlife Interactions

Scavengers play critical roles in ecosystem health and stability, and both biotic and abiotic factors can influence scavenger guild dynamics. Carrion is often limited both temporally and spatially on the landscape, but mass mortality events (MMEs)—in which there is an influx of carrion biomass on the landscape—may result in different scavenger community dynamics compared to when carrion is scarcely distributed. In this study, we investigated factors affecting the discovery and use of carrion by a natural, unharrassed scavenger guild during wild pig (Sus scrofa) MMEs conducted at East Foundation’s San Antonio Viejo Ranch in South Texas, USA. We …

Bird Strikes During Climb And Approach: A Need For Innovative Management Strategies, Richard A. Dolbeer, Michael J. Begier

Human–Wildlife Interactions

Wildlife Hazard Management Plans at civil airports in the United States cannot directly address threats posed by birds moving through aircraft climb and approach paths unrelated to nearby bird-attractant habitats such as landfills. As an iconic example, an Airbus 320 departing LaGuardia Airport (New York, USA) on January 15, 2009, struck a flock of migratory Canada geese (Branta canadensis) 8 km out at 884 m above ground level (AGL) that resulted in a water landing now known as the “Miracle on the Hudson.” We documented 1,841 and 458 strikes from 2009 to 2023 involving large (≥1.8 kg) and …

Refine Fuels Treatments In The Wildland–Urban Interface With Wildlife In Mind, Miles Becker, Catrin M. Edgeley, David Stoner

Human–Wildlife Interactions

Conserving urban tree and shrub cover provides many benefits for wildlife and people, yet often becomes a lower priority than fuels treatments to mitigate fire risk in the wildland–urban interface (WUI). We support the principle that considering multiple objectives on privately owned property is valuable and can be achieved. Data sharing and collaboration between wildfire experts and wildlife biologists could improve the quality and extent of managing both animals and fire. Furthermore, the adoption of statewide policy and municipal regulations for preventing wildfires in the WUI provides an opportunity to incorporate ecological functions in the same directives for a balanced …

Using Advanced Machine Learning To Evaluate The Spatial And Temporal Patterns Of Human–Bear Interactions In Maryland, Usa, Katherine A. Kurth, Jonathan K. Trudeau

Human–Wildlife Interactions

American black bears (Ursus americanus) are highly adaptable to human-dominated areas, which can lead to interactions with humans. Managing these interactions is a priority for many wildlife agencies in North America. Climate-induced shortages in natural food can exacerbate human–bear interactions, as bears are driven to seek alternative food sources in human-dominated areas. However, few studies have investigated the impact of climate or weather on the frequency and severity of human–bear interactions. In Maryland, USA, no research has examined the anthropogenic or environmental factors contributing to human–bear interactions, even though reported interactions have consistently increased since the 1990s. Our …

Racial-Ethnic Differences In The Associations Between Functional Disabilities And Subsequent Depression Among Community-Dwelling Midlife And Older Adults In The Us, Debasree Das Gupta, Uma Kelekar, Kallol Kumar Bhattacharyya, Sidney Carl Turner

Kinesiology and Health Science Faculty Publications

Background: The intersection of race/ethnicity with disability is a critical dimension of mental health outcomes in later ages that remains under-investigated.

Objective: We examined the role of race-ethnicity in moderating the associations between functional disabilities and subsequent depression among Americans 51 and older and stratified into the two age-groups of midlife (51-64) and older adults (≥65).

Methods: Using a nationally representative sample of community-dwelling Americans (≥51; n=7,475) in the 2016-2018 Health and Retirement Study, we conducted bivariate and multivariable regression analyses. Racial-ethnic groups included non-Hispanic (NH) Black, Hispanic, and NH White and a binary (0/1) outcome defined subsequent depression in …

Urban Coyotes As A Source Of Conflict With Humans: An Evaluation Of Common Management Practices, Paul D. Curtis, David L. Bergman, Angeline Barker, Daniel Bogan, Mary Ann Bonnell, Pierre Canac-Marquis, David Drake, Dave Kay, Brian F. Wakeling, H. Bryant White

Human–Wildlife Interactions Monographs

Wildlife often serves as a catalyst for conflict among stakeholders. Management actions that are intended to address sources of disagreement may initiate additional conflict. The Association of Fish and Wildlife Agencies Human–Wildlife Conflict Working Group initiated an effort to identify management actions commonly used to address unwanted coyote (Canis latrans) interactions within urban environments and identify the benefits and challenges associated with each action. Challenges with coyotes in urban environments include aggressive behavior toward humans and pets, attacks, disease exposure, and domestic livestock damage. Although elimination of all attractants would prove preventative in most instances, in practice this …

Hearing From Working Nurses: Incorporating Real-World Knowledge Practices Into The Framework To Better Instruct Tomorrow’S Healthcare Professionals, Anne R. Diekema, Elizabeth (Betsy) S. Hopkins, Britt Fagerheim, Brandon Patterson, Nena Schvaneveldt

Library Faculty & Staff Publications

There is a certain duality to the role of librarians in higher education as the job requires preparing students for their current academic work, such as doing research for writing papers, while at the same time preparing students for their future professional information work.¹ Librarians seeking guidance on teaching information literacy more comprehensively are left to study the professional standards of the targeted professional group,² and find or carry out research on these practitioners.³ Synthesizing and translating these findings into instructional approaches while staying true to existing information literacy standards, however, can be challenging.⁴ In this …

Using the Learning at the Boundaries framework, we analyze design team meetings, teacher feedback, and co-designed curricular materials. Our findings highlight the roles of boundary spanners, practices, and objects in bridging gaps among stakeholders and fostering sustainable collaboration. This research contributes to the learning sciences by documenting effective processes for organizational learning, emphasizing the importance of structured co-design in educational improvement.

Exploring Biostimulant Efficacy Under Limited Fertilizer And Water In Utah's Watermelon Production, Evan Christensen, Milena Oliveira, Prakriti Nepal, Youping Sun

Plants, Soils and Climate Student Research

The western U.S. has recently experienced some of the driest conditions on record, and Utah has been in a multi-year drought (2019-2023) that affected the agricultural sector, including vegetable producers. While vegetables are not a primary agricultural crop in Utah, they are still an important part of the horticultural economy with 763 farms growing 6,138 acres. As the fourth largest acreage vegetable crop in Utah (almost 10% of the acreage) watermelon and related crops in the gourd family Cucurbitaceae (nearly 36% of total vegetable acreage) are important to vegetable growers. Watermelon is a water-intensive crop and requires an adequate supply …

Turbo Fladry Fencing To Mitigate Short-Term Agricultural Damage Caused By Wild Pigs, Michael P. Glow, Jesse A. Tussing, Johnathan G. Walls, Robert B. Hyle, Joseph M. Halseth, Nathan P. Snow, Kurt C. Vercauteren

Human–Wildlife Interactions

Wild pigs (Sus scrofa) are a destructive invasive species that damage agricultural crops in many regions of the world. Lethal techniques to reduce populations are most often used to mitigate damage, but additional techniques are also needed in conjunction with lethal tools to protect resources in some settings (e.g., where lethal control is not practical or possible to achieve population elimination). While additional tools such as deterrents or temporary fencing may provide short-term relief, few effective options are currently available because habituation by wild pigs often reduces long-term effectiveness. Turbo fladry, a type of electric fence, is an …

Identifying The Types Of Collective Engagement Structures That Manifest In Middle Grade Mathematics Classrooms, Tye G. Campbell, Michael A. Lawson, Erin Rich, Sheunghyun Yeo, W. Boden Robertson

Teacher Education and Leadership Faculty Publications

While the potential of collaborative problem solving in mathematics is well known, facilitating effective group work is often challenging. One reason for this persistent difficulty educators face with collaborative problem solving can be traced to research and practice models that are not well-equipped to attend to the complexity of group work. The emerging construct of “collective engagement structures” represents one novel framework designed to attend to the complexity and variation of individual and group experience in collaborative problem solving. This study extends initial theorizing on collective engagement by offering descriptive accounts of the different types of collective engagement structures that …

Comparison Of Three Chimeric Zika Vaccine Prototypes Developed On The Genetic Background Of The Clinically Proven Live-Attenuated Japanese Encephalitis Vaccine Sa14-14-2, Byung-Hak Song, Jordan C. Frank, Sang-Im Yun, Justin G. Julander, Jeffrey B. Mason, Irina A. Polejaeva, Christopher J. Davies, Kenneth L. White, Xin Dai, Young-Min Lee

Animal, Dairy, and Veterinary Science Student Research

Zika virus (ZIKV) is a medically important mosquito-borne orthoflavivirus, but no vaccines are currently available to prevent ZIKV-associated disease. In this study, we compared three recombinant chimeric viruses developed as candidate vaccine prototypes (rJEV/ZIKV^MR-766, rJEV/ZIKV^P6-740, and rJEV/ZIKV^PRVABC-59), in which the two neutralizing antibody-inducing prM and E genes from each of three genetically distinct ZIKV strains were used to replace the corresponding genes of the clinically proven live-attenuated Japanese encephalitis virus vaccine SA₁₄-14-2 (rJEV). In WHO-certified Vero cells (a cell line suitable for vaccine production), rJEV/ZIKV^P6-740 exhibited the slowest viral growth, formed …

Weed Incursion Of Irrigated Forage–Forb Mixtures Under Mob Grazing Or Mowing In The Mountain West Usa, Jennifer Macadam, Jared Gibbons, Xin Dai

Plants, Soils, and Climate Faculty Publications

Improving the quality of irrigated pastures can increase the profitability of ruminant production systems. Increasing pasture plant biodiversity is beneficial for ruminants, pollinators, and soil health, but it is challenging to manage weed incursion in seeded mixed-species pastures. This study assessed the weed incursion that resulted when forage legumes or grasses were seeded as binary mixtures with one of four non-legume forbs. Defoliation occurred at 6-week intervals as either mowing or mob grazing. Forbs were chicory, plantain, Lewis flax, or small burnet and forages were alfalfa, birdsfoot trefoil, creeping foxtail, intermediate wheatgrass, kura clover, meadow bromegrass, orchardgrass, perennial ryegrass, reed …

Function Over Form: The Benefits Of Aspen As Surrogate Brood-Rearing Habitat For Greater Sage-Grouse, Michel T. Kohl, Charles P. Sandford, Paul C. Rogers, Renee Chi, Terry A. Messmer, David K. Dahlgren

Aspen Bibliography

Species of conservation concern are often habitat specialists, posing significant risk to those species when specific plant communities are threatened. As a result, practitioners habitually focus conservation efforts on these communities while ignoring ecological mechanisms that explain the wildlife–plant relationships. In doing so, practitioners may overlook alternative vegetation communities that could maintain wildlife populations under alternative conditions (e.g., climate change). Here, we term these areas surrogate habitat, defined as vegetation communities or resource sites that provide similar critical resources as conventional sites, and assess their potential for conservation using a case study of greater sage-grouse (Centrocercus urophasianus) on …

Changes In Climate And Their Implications For Cattle Nutrition And Management, Bashiri Iddy Muzzo, R. Douglas Ramsey, Juan J. Villalba

Wildland Resources Faculty Publications

Climate change is a global challenge that impacts rangeland and pastureland landscapes by inducing shifts in temperature variability, precipitation patterns, and extreme weather events. These changes alter soil and plant conditions, reducing forage availability and chemical composition and leading to nutritional stress in cattle. This stress occurs when animals lack adequate water and feed sources or when these resources are insufficient in quantity, composition, or nutrient balance. Several strategies are essential to address these impacts. Genetic selection, epigenetic biomarkers, and exploration of epigenetic memories present promising avenues for enhancing the resilience of cattle populations and improving adaptation to environmental stresses. …
