Impacts Of Climate Change And Agricultural Practices On Nitrogen Processes, Genes, And Soil Nitrous Oxide Emissions: A Quantitative Review Of Meta-Analyses, Dafeng Hui, Avedananda Ray, Lovish Kasrija, Jaekedah Christian

Biology Faculty Research

Microbial-driven processes, including nitrification and denitrification closely related to soil nitrous oxide (N2O) production, are orchestrated by a network of enzymes and genes such as amoA genes from ammonia-oxidizing bacteria (AOB) and archaea (AOA), narG (nitrate reductase), nirS and nirK (nitrite reductase), and nosZ (N2O reductase). However, how climatic factors and agricultural practices could influence these genes and processes and, consequently, soil N2O emissions remain unclear. In this comprehensive review, we quantitatively assessed the effects of these factors on nitrogen processes and soil N2O emissions using mega-analysis (i.e., meta-meta-analysis). The results showed that global warming increased soil nitrification and denitrification …

Birds, Bats And Minds. Tales Of A Revolutionary Scientist: Donald R. Griffin. Volume Two, Carolyn A. Ristau

eBooks

In this three-volume biography, we revisit the life and accomplishments of the revolutionary scientist, Donald R. Griffin. He encountered a lifetime of initial hostile resistance to his ideas and studies; now they are largely accepted. He and a colleague discovered the phenomenon of echolocation used by bats to navigate and capture insects, proposed that birds navigate guided by such cues as the sun and stars, and suggested that animals are likely aware, thinking and feeling beings. Forty interviews with his colleagues and friends help us understand the young emerging scientist and the mature researcher. We learn about his and others’ …

Assessment Of Salivary Cadmium Levels And Breast Density In The Marin Women's Study, Michaela F. George, Shayne Paff, Jenyse Rojo, Mark Powell, Christopher Benz, Karl Pope, Karla Kerlikowske, John Shepard, Matthew Willis, Rochelle Ereman, Leeann Prebil

Global Public Health | Faculty Scholarship

Background: We aimed to determine if salivary cadmium (Cd) levels had any association with breast density, hoping to establish a less invasive cost-effective method of stratifying Cd burden as an environmental breast cancer risk factor.

Methods: Salivary Cd levels were quantified from the Marin Women's Study, a Marin County, California population composite. Volumetric compositional breast density (BDsxa) data were measured by single x-ray absorptiometry techniques. Digital screening mammography was performed by the San Francisco Mammography Registry. Radiologists reviewed mammograms and assigned a Breast Imaging-Reporting and Data System score. Early morning salivary Cd samples were assayed. Association analyses were then …

Estimating Lentic Recreational Fisheries Catch And Effort Across The United States, Matthew D. Robertson, Stephen R. Midway, Holly S. Embke, Anna L. Kaz, Mitchel Lang, Craig Paukert, Nicholas A. Sievert, Lyndsie Wszola, Abigail J. Lynch

Faculty Publications

Recreational fisheries represent a socially, ecologically, and economically significant component of global fisheries. The U.S. Inland Creel and Angler Survey Catalog (CreelCat) database includes inland recreational fisheries survey data across the United States to facilitate large-scale analyses. However, because survey methods differ, a statistical method capable of integrating these surveys is necessary to assess patterns and relationships across regions. Here, we developed a hierarchical generalized linear mixed modeling approach to estimate the relationship between daily recreational fisheries catch and effort based on waterbody, socio-economic, and ecological covariates. We applied this approach to CreelCat data on lentic waterbodies and found that …

Autonomy And Free Thought In Brain- Computer Interactions: Review Of Legal Precedent For Precautionary Regulation Of Consumer Products, Sadia Khan, Daniel Cole, Hamid Ekbia

UC Law Science and Technology Journal

The expanding use of neurotechnologies in consumer products increases the risks to human rights such as autonomy and free thought. While potentially beneficial in clinical applications, technologies such as brain implants and EEG-enabled wearable devices pose serious concerns about mental and psychological manipulation of human beings. In the US in particular, law and policy are lagging behind technical developments, thereby increasing the risks of abuse and misuse from commercial neurotechnologies. This article focuses on commercial neurotechnologies, which are distinct from medical neurotechnologies for clinical diagnoses, and seeks to guard against human rights risks to users by overcoming that regulatory gap. …

A Look Into Nagpra: Application, Issues, And The Future, Gabrielle Despain

Wyoming Law Review

During Colonization, American Indian tribes lost homes, language, and culture. The Native American Grave Protection and Repatriation Act (NAGPRA) was passed to help rebuild the relationship with American Indian tribes after it had been destroyed during colonization. NAGPRA sets forth laws regarding the repatriation of remains and cultural objects which are being held in museums and by federal agencies. The legislative history behind this act shows Congress worked hard to find the best device to help with repatriation. However, NAGPRA’s language left holes in the law which led to different issues argued in litigation. Many American Indians began feeling that …

Do aspen smother or stoke the flames?

Kristin Nesbit

Perhaps you’ve heard of—or seen—fires decreasing in intensity (or extinguishing altogether) when they encounter an aspen stand. For a long time, firefighters, managers, and ecologists have characterized aspen forests as being low flammability, fire-resistant, “firebreak” forest types after observations of crown fires in conifer forests suddenly dropping down to surface fires upon entering adjacent aspen stands. However, high-intensity fires do spread through aspen-dominated forests, and aspen is known to regenerate vigorously after fire. For my M.S. research at Utah State University, I sought to explore this apparent paradox of aspen’s relationship …

A Design Thinking Mixed Methods Study On Learned Empathy Through Multicultural Education, Samanantha Webb

Dissertations

The dissertation in practice focused on addressing the issue of inadequate diversity, equity, and inclusion (DEI) competencies among teachers in a Title I school. The problem of practice emerged within the context of an increasingly diverse educational landscape, necessitating educators to possess robust DEI skills. The proposed solution was a professional development (PD) program, crafted using a design thinking approach, which included an asynchronous learning module supplemented by a book study. The comprehensive PD program was aimed at enhancing the teachers' understanding and application of DEI principles, making the prototype relevant to the demands of multicultural education in today’s diverse …

A Design-Based, Mixed Methodology Study On Neurodiversity-Affirming Practices Among Speech-Language Pathologists In A Midwestern School District, Sarah E. Schmid

Dissertations

As autism diagnosis increased (Maenner et al., 2023; Wright, 2017), autistic individuals increasingly advocated for services aligned with a neurodiversity perspective (Jordan, 2010; Leadbitter et al., 2021). Using a human centric, design-based approach, the researcher identified a lack of alignment between the emerging preferences of the autistic community and the services speech-language pathologists (SLPs) in a large, suburban special education school district felt competent in providing. Some SLPs in the district reported a lack of knowledge and training about the neurodiversity movement and felt further training on the topic was needed. Once the knowledge gap was identified, the researcher worked …

Mathematical Model Of Oxygen, Nutrient, And Drug Transport In Tuberculosis Granulomas, Meenal Datta, Mccarthy Kennedy, Saeed Siri, Laura Via, James W. Baish, Lei Xu, Veronique Dartois, Clifton Barry, Rakesh Jain

Faculty Journal Articles

Physiological abnormalities in pulmonary granulomas–pathological hallmarks of tuberculosis (TB)–compromise the transport of oxygen, nutrients, and drugs. In prior studies, we demonstrated mathematically and experimentally that hypoxia and necrosis emerge in the granuloma microenvironment (GME) as a direct result of limited oxygen availability. Building on our initial model of avascular oxygen diffusion, here we explore additional aspects of oxy- gen transport, including the roles of granuloma vasculature, transcapillary transport, plasma dilution, and interstitial convection, followed by cellular metabolism. Approximate analytical solutions are provided for oxygen and glucose concentration, interstitial fluid velocity, interstitial fluid pressure, and the thickness of the convective zone. …

The Right To A Healthy Environment In Latin America And The Caribbean: Compliance Through The Inter-American System And The Escazú Agreement, Maria Antonia Tigre

Sabin Center for Climate Change Law

The Escazú Agreement has brought a myriad of environmental rights and duties to Latin America and the Caribbean (LAC), including the recognition of a right to a healthy environment and rights of environmental defenders. As a new agreement, the task of implementing the Escazú Agreement still lies ahead. Significantly, a non-judicial, non-punitive, consultative and transparent Committee to support Implementation and Compliance was established as a subsidiary body of the Conference of the Parties to promote implementation. Concomitantly, the Inter-American Court of Human Rights recognised an autonomous right to a healthy environment, establishing it as directly justiciable within the Inter-American System …

Expanding Karst Groundwater Tracing Techniques: Incorporating Population Genetic And Isotopic Data To Enhance Flow-Path Characterization, Benjamin Tobin, Benjamin V. Miller, Matthew Niemiller, Andrea Erhardt

Earth and Environmental Sciences Faculty Publications

Karst aquifers are unique among groundwater systems because of variable permeability and flow-path organization changes resulting from dissolution processes. Over time, changes in flow-path connectivity complicate interpretations of conduit network evolution in karst hydrogeology. Natural and artificial tracer techniques have long provided critical information for protecting karst aquifers and understanding the potential impacts on ecosystems and human populations. Conventional tracer methods are useful in karst hydrogeologic studies for delineating flow paths and defining recharge, storage, and discharge properties. However, these methods only provide snapshots of the current conditions and do not provide sufficient information to understand the changes in interconnection …

Preferential Binding Of Polyphenols In Blackcurrant Extracts With Milk Proteins And The Effects On The Bioaccessibility And Antioxidant Activity Of Polyphenols, Ting Mao, Fnu Akshit, Iresha Matiwalage, Subha Sasidharan, Caren Meyn Alvarez, Philip Wescombe, Maneesha S. Mohan

Dairy Science and Food Science Faculty Publications: 2022 to Present

Milk proteins are well-known delivery agents; however, there is no clear understanding of the competitive interactions of milk proteins with polyphenols in mixed complex systems. Here, we investigate the preferential competitive interactions of different polyphenols present in blackcurrant extract with milk proteins by quantifying the protein-bound polyphenols and comparing the factors affecting these interactions. In addition, bioaccessibility and antioxidant activity were studied after in vitro gastric digestion. Our results indicated that polyphenols from blackcurrant extracts were preferentially bound to caseins more than whey proteins, with noncovalent interactions causing secondary structural changes in the protein. The hydrophobicity and the charge of …

Plant Protein Flavor Chemistry Fundamentals And Techniques To Mitigate Undesirable Flavors, Serap Vatansever, Bingcan Chen, Clifford Hall

Dairy Science and Food Science Faculty Publications: 2022 to Present

Many plant protein ingredients have unpleasant flavor (e.g., green, beany, bitterness) characteristics. Isolation of the protein fraction will reduce the intensity of the undesirable flavors but in most cases the flavor issue is not eliminated. The objective of this review is to provide information about undesirable flavors associated with plant proteins and approaches to mitigate these flavors. The focus of the review will be on flavor associated with plant proteins from pulses, soybean, and oilseeds (e.g., hempseed, flaxseed). While other plant proteins exist, they will not be covered extensively in this limited review. The undesirable flavors are defined as volatile …

Towards Responsible Quantum Technology: Safeguarding, Engaging And Advancing Quantum R&D, Mauritz Kop, Mateo Aboy, Eline De Jong, Urs Gasser, Timo Minssen, I. Glenn Cohen, Mark Brongersma, Teresa Quintel, Luciano Floridi, Raymond Laflamme

UC Law Science and Technology Journal

The expected societal impact of quantum technologies (QT) urges us to proceed and innovate responsibly. This article proposes a conceptual framework for Responsible QT that seeks to integrate considerations about ethical, legal, social, and policy implications (ELSPI) into quantum R&D, while responding to the Responsible Research and Innovation dimensions of anticipation, inclusion, reflection and responsiveness. After examining what makes QT unique, we argue that quantum innovation should be guided by a methodological framework for Responsible QT, aimed at jointly safeguarding against risks by proactively addressing them, engaging stakeholders in the innovation process, and continue advancing QT (‘SEA’). We further suggest …

One Nation, Under Dobbs: How Dobbs V. Jackson Women’S Health Impacts Data Privacy For All, Mikayla Domingo

UC Law Science and Technology Journal

The Supreme Court has gone against the fundamental principle of Stare Decisis in Dobbs v. Jackson Women’s Health Organization, holding that the constitution confers no right to an abortion. The aftermath of Dobbs shines a spotlight on how reproductive and feminine health data are exploited to target women. From geolocation monitoring to abortion clinics, to women’s search history and private messages being used in her prosecution, the dystopian prospect of surveillance capitalism is now reality for women in the United States. The immediate impact of Dobbs illuminates the need for greater and clearer data privacy protections have never been more …

Taxonomic Advances Driven By The Genomic Analysis Of Butterflies, Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

This study presents new findings based on a large-scale analysis of butterfly genomic sequences. Focusing on species identification through comparative genomics, we define subspecies as populations differentiated to a lesser extent than distinct species ("species in the making"). Additionally, we propose further adjustments to the current butterfly classification. As a result, 3 subgenera, 12 species, and 4 subspecies are described as new. New subgenera are (type species in parenthesis): Hyalaus Grishin, subgen. n. (Papilio epidaus E. Doubleday, 1846) of Eurytides Hübner, [1821] (Papilionidae Latreille, [1802]) and Astria Grishin, subgen. n. (Lycaena astraea Freyer, 1851) of Glaucopsyche Scudder, 1872 …

Genetic Context Drives Age-Related Disparities In Synaptic Maintenance And Structure Across Cortical And Hippocampal Neuronal Circuits., Sarah E Heuer, Emily W Nickerson, Gareth R Howell, Erik B Bloss

Faculty Research 2024

The disconnection of neuronal circuitry through synaptic loss is presumed to be a major driver of age-related cognitive decline. Age-related cognitive decline is heterogeneous, yet whether genetic mechanisms differentiate successful from unsuccessful cognitive decline through maintenance or vulnerability of synaptic connections remains unknown. Previous work using rodent and primate models leveraged various techniques to imply that age-related synaptic loss is widespread on pyramidal cells in prefrontal cortex (PFC) circuits but absent on those in area CA1 of the hippocampus. Here, we examined the effect of aging on synapses on projection neurons forming a hippocampal-cortico-thalamic circuit important for spatial working memory …

Interdependencies Between Wildfire-Induced Alterations In Soil Properties, Near-Surface Processes, And Geohazards, Farshid Vahedifard, Masood Abdollahi, Ben A. Leshchinsky, Timothy D. Stark, Mojtaba Sadegh, Amir Aghakouchak

Civil Engineering Faculty Publications and Presentations

The frequency, severity, and spatial extent of destructive wildfires have increased in several regions globally over the past decades. While direct impacts from wildfires are devastating, the hazardous legacy of wildfires affects nearby communities long after the flames have been extinguished. Post-wildfire soil conditions control the persistence, severity, and timing of cascading geohazards in burned landscapes. The interplay and feedback between geohazards and wildfire-induced changes to soil properties, land cover conditions, and near-surface and surface processes are still poorly understood. Here, we synthesize wildfire-induced processes that can affect the critical attributes of burned soils and their conditioning of subsequent geohazards. …

Geotechnical Characterisation Of Coal Spoil Piles Using High-Resolution Optical And Multispectral Data: A Machine Learning Approach, Sureka Thiruchittampalam, Bikram Pratap Banerjee, Nancy F. Glenn, Simit Raval

Geosciences Faculty Publications and Presentations

Geotechnical characterisation of spoil piles has traditionally relied on the expertise of field specialists, which can be both hazardous and time-consuming. Although unmanned aerial vehicles (UAV) show promise as a remote sensing tool in various applications; accurately segmenting and classifying very high-resolution remote sensing images of heterogeneous terrains, such as mining spoil piles with irregular morphologies, presents significant challenges. The proposed method adopts a robust approach that combines morphology-based segmentation, as well as spectral, textural, structural, and statistical feature extraction techniques to overcome the difficulties associated with spoil pile characterisation. Additionally, it incorporates minimum redundancy maximum relevance (mRMR) based feature …
