Electrocoagulation For Removal Of Nitrates From Fgd Wastewater, Jacob Watkins, Julissa Van Renselaar, Amanda Moravek, Tallon Beckstrom, Shaylynn Cannon

Biological Engineering

Flue gas desulfurization (FGD) processes are often utilized to mitigate pollution from coal-based plants by removing sulfur oxides¹. However, FGD wastewater streams still contain pollutants such as nitrates that must undergo further treatment². The Environmental Protection Agency (EPA) has Effluent Limitation Guidelines (ELG) that dictate the allowable concentrations of the contaminants in FGD wastewater effluent. While common treatment approaches can meet these requirements, efficiency drops with chemical concentration flux, which is a common situation with FGD wastewater. A novel method that could both meet ELG requirements and handle chemical concentration flux is electrocoagulation (EC). EC is able to target a …

Integrating Storytelling Into The Theory And Practice Of Contextual Behavioral Science, Carter H. Davis, Brandon A. Gaudiano, Louise Mchugh, Michael E. Levin

Psychology Student Research

The practice of generating and interpreting stories can be examined through a behavioral lens and has many potential implications for clinical practice. However, storytelling has for the most part yet to be integrated into the field of contextual behavioral science (CBS). A bedrock of human culture, storytelling has influenced both individual behavior and intergroup cooperation for millennia. Basic principles of relational frame theory, such as those pertaining to coherence, perspective-taking, and the transformation of stimulus function, may help to reveal how stories derive their psychological impact. In turn, understanding storytelling from a CBS perspective can facilitate the broader integration of …

Debugging By Design: A Constructionist Approach To High School Students’ Crafting And Coding Of Electronic Textiles As Failure Artifacts, Deborah A. Fields, Yasmin B. Kafai, Luis Morales-Navarro, Justice T. Walker

Instructional Technology and Learning Sciences Faculty Publications

Much attention in constructionism has focused on designing tools and activities that support learners in designing fully finished and functional applications and artifacts to be shared with others. But helping students learn to debug their applications often takes on a surprisingly more instructionist stance by giving them checklists, teaching them strategies or providing them with test programs. The idea of designing bugs for learning—or debugging by design—makes learners agents of their own learning and, more importantly, of making and solving mistakes. In this paper, we report on our implementation of “Debugging by Design” activities in a high school classroom over …

The whole of Division I, as well as the three subdivisions, were examined for the five-year period from 2013 …

A Decision Tool To Identify Population Management Strategies For Common Ravens And Other Avian Predators, Andrea F. Currylow, Brenda J. Hanley, Kerry L. Holcomb, Timothy Shields, Stephen Boland, William I. Boarman, Mercy Vaughn

Human–Wildlife Interactions

Some avian species have developed the capacity to leverage resource subsidies associated with human manipulated landscapes to increase population densities in habitats with naturally low carrying capacities. Elevated corvid densities and new territory establishment have led to an unsustainable increase in depredation pressure on sympatric native wildlife prey populations as well as in crop damage. Yet, subsidized predator removal programs aimed at reducing densities are likely most effective longer-term when conducted in tandem with subsidy control, habitat management, and robust assessment monitoring programs. We developed decision support software that leverages stage structured Lefkovitch population matrices to compare and identify treatment …

Monograph Reduced Box Price: Managing Human–Deer Conflicts

Human–Wildlife Interactions

Order form for HWI monograph, Methods for Managing Human–Deer Conflicts in Urban, Suburban, and Exurban Areas. This monograph identifies challenges and benefits associated with many human–deer conflict mitigation actions as well as methods to monitor the response of deer populations to management actions. Deer exploit urban, suburban, and exurban areas where human populations provide anthropogenic attractants, either intentionally or inadvertently, which often leads to human–deer conflicts. Mitigating actions have varying degrees of efficacy and may not be effective or accepted in every situation. Wildlife and municipal managers must work together to seek methods to reduce attractants, mitigate conflicts, and perpetuate …

Spatial Modeling Of Common Raven Density And Occurrence Helps Guide Landscape Management Within Great Basin Sagebrush Ecosystems, Sarah C. Webster, Shawn T. O'Neil, Brianne E. Brussee, Peter S. Coates, Pat J. Jackson, John C. Tull, David J. Delehanty

Human–Wildlife Interactions

Common ravens (Corvus corax; ravens) are a behaviorally flexible nest predator of several avian species, including species of conservation concern. Movement patterns based on life history phases, particularly territoriality of breeding birds and transiency of nonbreeding birds, are thought to influence the frequency and efficacy of nest predation. As such, predicting where on the landscape territorial resident and non-territorial transient birds may be found in relation to the distribution of sensitive prey is of increasing importance to managers and conservationists. From 2007 to 2019, we conducted raven point count surveys between mid-March and mid-September across 43 different field …

Influence Of Anthropogenic Subsidies On Movements Of Common Ravens, Adam E. Duerr, Peter H. Bloom, Kerry Ross, Tricia A. Miller, Melissa A. Braham, Amy L. Fesnock, Todd E. Katzner

Human–Wildlife Interactions

Anthropogenic subsidies can benefit populations of generalist predators such as common ravens (ravens; Corvus corax), which in turn may depress populations of many types of species at lower-trophic levels, including desert tortoises (Gopherus agassizii) or greater sage-grouse (Centrocercus urophasianus). Management of subsidized ravens often has targeted local breeding populations that are presumed to affect species of concern and ignored “urban” populations of ravens. However, little is known about how ravens move, especially in response to the presence of anthropogenic subsidies. Therefore, subsidized ravens from distant populations that are not managed may influence local prey. To …

Synthesis Of Nest Predation Impacts Of Common Ravens On Sensitive Avian Species, Peter S. Coates, William C. Webb, Seth J. Dettenmaier, Seth M. Harju, David J. Delehanty

Human–Wildlife Interactions

Decades of mounting scientific evidence have revealed that common raven (Corvus corax; raven) population numbers have been increasing across nearly all regions of their geographic range in North America. Concomitantly, numerous native wildlife species have experienced elevated predation rates from ravens as populations have increased and expanded their range. Managers are concerned that increased raven predation of many threatened and endangered avian species in the U.S. and Canada during nesting periods may be hampering species recovery. We explored the literature to aggregate existing knowledge and evaluate the impacts of raven predation on nests and young of sensitive avian …

Common Raven Impacts On Nesting Western Snowy Plovers: Integrating Management To Facilitate Species Recovery, Cheryl Strong, Kriss K. Neuman, Jenny L. Hutchinson, Jamie K. Miller, Amber L. Clark, Lena Chang, Joanna Iwanicha, Elizabeth Feucht, Matthew J. Lau, David J. Lauten, Sarah Markegard, Benjamin Pearl, David L. Sherer, Rachel Tertes, Susie Tharratt, Travis Wooten

Human–Wildlife Interactions

The U.S. Pacific coast population of the western snowy plover (Charadrius nivosus nivosus; plover) has declined due to loss and degradation of coastal habitats, predation, and anthropogenic disturbance. The U.S. Fish and Wildlife Service listed the subspecies in 1993 as threatened under the Endangered Species Act due to the population declines and habitat loss. Predation of nests and chicks has been identified as an important cause of historic population declines, and thus, most predator management actions for this subspecies are focused on reducing this pressure. In recent years, common ravens (Corvus corax; ravens) have become the most …

Inter- And Intra-Annual Effects Of Lethal Removal On Common Raven Abundance In Nevada And California, Usa, Shawn T. O'Neil, Peter S. Coates, Julia C. Brockman, Pat J. Jackson, Jack O. Spencer Jr., Perry J. Williams

Human–Wildlife Interactions

Populations of common ravens (Corvus corax; ravens) have increased rapidly within sagebrush (Artemisia spp.) ecosystems between 1960 and 2020. Although ravens are native to North America, their population densities have expanded to levels that negatively influence the population dynamics of other wildlife species of conservation concern, such as greater sage-grouse (Centrocercus urophasianus) and desert tortoises (Gopherus agassizii). For this reason, lethal removal, such as the application of the avicide DRC-1339, has been used to manage raven numbers at local scales and under certain circumstances. Because the relative effectiveness of DRC-1339 in reducing raven …

Raven Control From A Conservation Biology Perspective, David J. Delehanty

Human–Wildlife Interactions

The common raven (Corvus corax; raven) is a large, highly intelligent passerine songbird with a Holarctic distribution attributable to a high degree of plasticity in its foraging and nesting behavior. Historically, ravens have received special attention in human culture, being either respected or vilified. In the western United States, ravens are exploiting the expanding human enterprise, which provides them with unintended subsidies of food, water, and breeding locations, allowing ravens to expand their range and increase in population density and resulting in raven depredation threatening species of conservation concern. From a conservation biology perspective, increased raven populations present …
