Full REC project description:

Collegiate esport programs have seen substantial investments in construction of facilities and personnel mirroring the athletics arm race in traditional sport (Hoofer et al., 2015). Despite such advancements, a lack of consensus exists in the management of collegiate esports programs. Collegiate esports athletes face similar issues as their traditional athlete counterparts including sexism (Ruvalcaba et al., 2018), homophobia (Xue et. al., 2019) racism (Fletcher, 2020), and ethical concerns (Funk et al., 2018). The definition of the competitive gamer aligns with that of the traditional athlete, while Esport has grown into a sanctioned sport at the collegiate and professional levels (Jenny et. al., 2017). Due to this growth, college institutions across the nation have funded the construction of esport facilities and formation of varsity esport teams housed within athletic departments; providing scholarship opportunities for esport athletes. The rapid growth and expansion of esport programs across the nation calls for examination of how esport athletes have adjusted to collegiate athletics; in particular how they form (and view) their athletic identity within the esport ecosystem.

List of synchronous scheduled dates/times and events:

Fieldwork: Friday October 4th at 4:00pm – Sunday October 6th at 2:00pm (This may be subject to change. However, fieldwork will start at 4:00pm on a Friday and end on a Sunday around 2:00pm).

Museum and Lab work: Tuesday October October 8th- Tuesday October 15th.

Full REC project description:

For this project, you will gain experience in three major aspects of work: fieldwork, museum installation, and lab work. First, you will have the opportunity to join Lexi and her advisor’s Mammalogy class to partake in fieldwork. While in the field, students will go out in groups, set lines (with different types of kill and non-kill traps), and collect animals the next morning (we do this for two days). In the morning, you will be able to observe how we holistically collect the specimens, meaning we take as much as possible. We take environmental data (how is the habitat around where we captured the animal), measurements of the animal (total length, ear length, tail length, foot length), external and internal reproductive information, parasites (both external like ticks and lice and internal like nematodes and cestodes), tissues (large intestine, muscle, liver, heart, and lung). Unfortunately, you will not be able to partake in this aspect, but you will be able to prepare mammal skins (along with other Mammalogy students) during their time in the field, which will then be installed in the Museum of Southwestern Biology collection.

After fieldwork, you will be given a tour of the Museum of Southwestern Biology Mammals Division and Division of Genomic Resources. You will see where your specimens and associated data will be deposited. You will also be walked through the process of museum installation and how integral museums are to understanding the past, present, and future of mammalian biodiversity.

Finally, the last week will be spent in the Cook Molecular Evolution and Ecology lab, where you will gain a general understanding of lab equipment and techniques used to generate DNA sequences. You will then learn how your generated sequences will be used to answer an array of different types of questions such as (but not limited to):

• How are different species related to one another?
• Are there cryptic species (look the same, but their DNA is different!) within a population?
• How have species moved through time? Are they expanding more northward due to climate change?
• How do species diverge in isolated environments? Do they have greater genetic diversity? Should we work to conserve these populations?

Required prerequisites:

Prior knowledge is not required. However, you should be comfortable with camping, as you will go out to the field to gain experience in the fieldwork portion of what we do! There will be no showers and possibly no bathrooms for a couple of days. I will email a gear list to everyone, and if you do not have certain items, we can work on renting from UNM’s Outdoor Adventure Center, REI, etc.

You must also be comfortable with handling deceased specimens that have been humanely euthanized (according to IUCAC). You will be creating skins from these specimens that will be installed in the Museum of Southwestern Biology. With that, you will be required to try your best at making these skins, as these will be in the museum collection and used for research purposes.

Description of project leader’s research:

Lexi Baca's research focuses on the evolutionary dynamics and biogeographical patterns within the family Dipodidae (including jerboas, jumping mice, and birch mice).

In her main study involving the genus Orientallactaga, which is a group of five-toed jerboas inhabiting central Asia, Lexi addresses the complexities of reconstructing evolutionary histories. This genus presents possible challenges, such as incomplete lineage sorting and asymmetric introgression (among others), which can lead to mitonuclear discordance, where the mitochondrial phylogenetic relationships are not in accordance with the nuclear phylogenetic relationships. To understand why this mitonuclear discordance is occurring, Lexi is generating and analyzing cytochrome b (a single mitochondrial gene) alongside ddRAD (double digest restriction site-associated DNA nuclear sequencing) data from 85 museum specimens across three species: O. balikunica, O. bullata, and O. sibirica. This analysis highlights the importance of analyzing mitochondrial and nuclear DNA independently to gain a comprehensive understanding of the evolutionary processes at play.

Lexi's research also extends to the genus Dipus, a group of three-toed jerboas, where she adopts a comparative phylogeographic approach between Dipus and Orientallactaga. Her goal is to compare the similarities and differences in demographic histories and ecological niches among distinct species that exhibit overlapping distributions and among closely related infraspecific clades. By utilizing a combination of phylogenetic trees, skyline plots, species distribution models, and niche identity tests, Lexi seeks to reveal the evolutionary dynamics and patterns that shape the diversity and coexistence of these two groups of jerboas.

In addition to her core projects, Lexi Baca is also collaborating on other research projects including:

• Lexi Baca, Mary Ferguson, Gwen Copland, Daniel Shaw, Jennifer K. Frey, Jason Malaney, Jonathan Dunnum, Joseph Cook: Is climate disruption influencing the northern range limits of wildlife in the Southwestern US?
• Lexi Baca, Joseph Cook, Ivanna Tomasco: A New Species of Andean Ctenomys (Rodentia: Ctenomyidate) Related to C. leucodon:
• Lexi Baca, Connor Burgin, Joseph Cook, Ivanna Tomasco: Contributions to the Knowledge of the Paraguayan tuco tuco, Ctenomys paraguayensis Contreras 2000 (Rodentia: Ctenomyidae)

This research project asks why some government security forces commit sexual violence against civilians while others do not. This project involves new data collection to study violence by state actors; to quantify which state actors engage in abuse and when. This research is quantitative in nature and will involve coding sentence excerpts from the U.S. Department of State Human Rights Country reports to create a dataset on sexual violence committed by government security forces. Data collection will be completed using an iterative process of human coding and AI natural language processing models.

APPLICATION DEADLINE: September 20, 2024

Participant Stipend: $450. This amount will be deposited in your bursar account as a departmental award. Department awards are considered financial aid, similar to grants or scholarships.

Project Lead: Margaret Avera, Political Science Department, PhD Candidate

Student Learning Outcomes: 

• Critical Reading
• Familiarity with a Codebook
• Basic Excel Skills
• Introduction to Data Collection

Starting date: September 30, 2024

Ending date: December 2, 2024

List of synchronous scheduled dates/times and events:

• Meetings Wednesday afternoon at 3:30pm (Preferred meeting time but not required).

Full REC project description:

Students will learn through weekly discussion, hands on experience, and interaction with myself, my faculty mentor, and other graduate students who will be coding. Students will gain insight into the creation of a codebook and, specifically, coding practices for use in AI natural language processing models. Students will participate in the iterative process of learning 'best-practices' for AI coding, therefore, students will gain experience with traditional coding and also learn how coding practices change when coding for an AI model. Participation in this data collection process will allow students to learn the basics of how AI models use input information and how to properly code information for model inputs.||Undergraduates will begin with an introduction to the literature on sexual violence focusing on actor type variation and prevalence of sexual violence variation. They will then participate in the coding process. The coding process will be partially done through AI language models; therefore, students will be selecting sentences based on their relevance to allegations of sexual violence. The students will use previous human coder logs to identify relevant sentences and then match those sentences to a csv file of the reports in sentence form. Students will find matching sentences to be fed into the AI language model and be part of the assessment process looking for model accuracy and solutions. Students will match sentences, then assess model output to analyze which sentences the model gets incorrect. Therefore, students will not only engage in research on how sexual violence data is coded but also learn how to use AI language models as a research tool.

Description of project leader’s research:

Sina’s focuses on how the risk of COVID-19 infection varied across different counties in the United States during the pandemic, and how the CDC's community risk level metrics were used to estimate this risk. These metrics helped guide decisions on infection prevention strategies. The CDC categorized counties into low, medium, or high risk based on factors like new cases, hospital admissions, and bed use. These risk levels determined actions like testing, isolation, masking, and vaccination.

The study aimed to understand how consistent these risk level assignments were over time and whether they changed frequently. To do this, you gathered data on COVID-19 cases, hospitalizations, and bed occupancy from public sources. You analyzed how often counties' risk levels stayed the same or changed, and you looked at the speed of these changes. Additionally, you explored how the rate of risk level change related to factors like county population size, urbanization level, and the number of hospitals.

In this research, Sina also compared the CDC's metrics with an alternative metric that predicts risk similarly. This alternative metric adjusted the threshold for hospital bed occupancy to 5% instead of 10%.

Overall, Sina’s study contributes to understanding how COVID-19 risk was assessed at the county level, how consistent these assessments were, and how different metrics compared in predicting risk. This information could help inform public health recommendations and strategies for managing the pandemic's impact. Link of the article: https://academic.oup.com/cid/article/76/8/1496/6847510

Full REC project description:

Petrified Forest National Park is dominated by Late Triassic Chinle Formation outcrops (~225 – 200 million years old) that contain an incredibly diverse assemblage of vertebrate fossils from archosaurs, early dinosaurs, fish, freshwater sharks, and more. Previous studies have determined that certain exposures within the park were deposited primarily by a megafan network, a type of river characterized by a series of branching channels and streams that end in a distal megafan. While DFS represent the majority of modern-day rivers within sedimentary basins, they are just now being recognized in the geologic record. As a result, we currently have no way to predict the occurrence/preservation of fossils along a DFS. We have generated preservation hypotheses for eight different DFS subenvironments, and have begun to test them by both visiting known fossil sites within PEFO and describing collected fossils within the museum. Identifying how fossils preserve in different DFS subenvironments (e.g. which taxa, what size, level of weathering, level of abrasion, presence of predatory/scavenging marks, etc.) could serve as an excellent predictive model to help find well-preserved fossils in the future. Students involved in this project will learn the basics of fossil deposition and preservation, how to locate fossilized bones and describe them taphonomically, and how to think of scientific questions in the context of deep time, all while discovering new fossils, making new friends, and camping under the Arizona sky.

Description of project leader’s research:

Alex’s research focuses primarily on how vertebrate taphonomy and paleoecology is affected by depositional position within a megafan network. By using statistical analyses on vertebrate fossil co-occurrence, she has previously been able to shed light on how Late Triassic paleocommunities surrounding this fluvial megafan may have interacted. This project will supplement those findings with taphonomic and sedimentologic descriptions, in order to determine how fossil assemblages and their preservation styles change based on which DFS subenvironment deposits them. The lab group of Dr. Jason Moore (which includes Alex) has been conducting a companion study on modern animal bones deposited along the Pilcomayo River in Paraguay, allowing correlations to be made with findings in Petrified Forest. With results from both studies, researchers aim to construct a framework for predicting preservation and species occurrence for DFS successions within the fossil record.

Neuroinflammation is a major hallmark of Alzheimer's disease. One of the key cytokines involved in neuroinflammation is IL-1beta. This cytokine requires IL-1 receptor accessory protein (IL-1RAP) for signaling. IL-1beta signaling results in downstream pro-inflammatory cytokine production. The goal of this study is to determine whether eliminating IL-1RAP or blocking its signaling-either genetically in mouse models or with FDA-approved small molecule drugs in cell culture-can regulate IL-1R1/IL-1RAP function to reduce neuroinflammation, tau pathology, and cognitive function.

Full REC project description:

This research project focuses on understanding the role of a protein called IL-1 receptor accessory protein (IL-1RAP) in Alzheimer's disease (AD). AD is a brain disorder that leads to memory loss and cognitive decline. In AD, a molecule called IL-1beta causes inflammation, which plays a key role in damaging brain cells and worsening the disease. IL-1beta works by binding to a receptor on the cell surface called IL-1R1, and this interaction requires another protein, IL-1RAP, to be effective. Interestingly, while IL-1RAP is linked to AD, it might also help reduce brain inflammation by activating certain immune cells called Type II innate lymphoid cells (ILC2s). These cells can protect the brain and improve cognitive function. Our project aims to explore this dual role of IL-1RAP in both promoting and potentially reducing inflammation in the brain. We will use genetically modified mice that lack either IL-1RAP or IL-1R1 to study how these proteins affect memory, brain inflammation, and the build-up of harmful tau proteins associated with AD. We'll also investigate how ILC2s influence these outcomes. Additionally, we'll search for small molecule drugs that can block the harmful effects of IL-1R1/IL-1RAP interactions in cell cultures. Students participating in this project will have the chance to observe/assist with one or more experiments, including mouse genotyping using PCR, testing memory in mice with the Morris Water Maze, analyzing brain samples for tau proteins using Western blotting and immunohistochemistry, studying ILC2s with flow cytometry, and screening potential drugs in cell cultures.

Description of project leader’s research:

Alzheimer's disease (AD) and related tauopathies are increasing cause of death due to dementia, yet there is no cure. IL-1beta-induced inflammation is critical in tau pathology and cognitive decline, mediated by IL-1R1 and its co-receptor IL-1RAP. While IL-1RAP is implicated in AD and other inflammatory processes, it also supports neuroprotective Type II innate lymphoid cells (ILC2s). This project investigates the dual role of IL-1RAP in neuroinflammation and tau pathology. Using IL-1RAP and IL-1R1 knockout mouse models, we will assess cognitive and pathological outcomes. Additionally, the role of ILC2s in modulating these effects will be examined. Lastly, small molecule inhibitors targeting the IL-1R1/IL-1RAP axis will be identified and tested, with a focus on specificity to IL-1RAP. This research aims to clarify IL-1RAP's role in AD and identify novel therapeutic strategies that may extend to other inflammatory diseases.

Antarctica is home to various lake systems that can help scientists understand how they have changed since the last ice age. At the depths of each lake, sediments and the minerals that precipitate from the water column can provide insight into the lake’s hydrology and climate in the past as they are preserved in the rock record. In this project, you will use samples from an Antarctic paleolake in Miers Valley, learn how to interpret carbonate rocks, and be introduced to geochemical methods to understand the evolution of these environments as a result of climate change.

List of synchronous scheduled dates/times and events: Meetings will be arranged around participant work and class schedules. Meetings will include the following sessions/topics:

• Introductions & Background on the McMurdo Dry Valleys
• Mackey Lab Group Introductions
• Introduction to Carbonates: Basics & Applications
• Methodologies & Motivating Question
• Petrography
• Cathodoluminescence
• Stable Isotopes
• Results & Synthesis
• Abstract Preparation

Full REC project description:

The McMurdo Dry Valleys (MDV) in Antarctica host several lakes with permanent ice cover year-round, known as perennially ice-covered lakes (PICLs, for short). These systems have been the subject of scientific research for decades in order to understand their hydrology, their microbiology, and the overall geologic and climatic history of the MDV. Our focus for this project will revolve around the mineralogy of Miers Valley, which consists dominantly of carbonate and gypsum, including potential pseudomorphs after ikaite, all of which exists as a result of environmental change since the Last Glacial Maximum.

To address the goals of this research, sessions will be designed to teach students the basics of carbonate mineralogy and their significance as environmental records, how to conduct petrographic interpretations, and the theory behind different geochemical methods (e.g., stable isotopes, cathodoluminescence). Students will have the opportunity to work hands-on with samples from Miers Valley and different instruments such as the petrographic microscope, as well as how to interpret data and write an effective abstract.

Required prerequisites:

Open for STEM majors (Geology, Environmental Science, Biology, Chemistry, etc.), or any student with an interest in earth sciences. No special skills are required.

Preferred prerequisites:

General Chemistry is encouraged but not required.

Number of undergraduate students who will be accepted into this REC project:

Description of project leader’s research:

Giovannetti-Nazario’s research revolves primarily around geochemistry. The geology of Antarctica’s McMurdo Dry Valleys consists of glacial and lacustrine deposits, as well as modern perennially ice-covered lakes. Because lakes with a permanent ice cover are unique to cold arid environments, they involve processes different from glacial or other lake deposits and are capable of providing insight into past climatic conditions. Giovannetti-Nazario will be looking at carbonate facies of two lake systems, modern Lake Fryxell and the paleolake deposits of Miers Valley, to understand how these environments changed over time. Novel geochemical techniques will be used coupled with petrography and facies observations to assess changes in water balance in Lake Fryxell’s past. This work will also help elucidate the paleoclimatic context of Miers Valley where stratigraphic observations, along with stable isotopes and geochronology, will be used to investigate the evolution of Lake Miers since the Last Glacial Maximum.

Students involved in this project will learn the basics of fossil deposition and preservation, how to locate fossilized bones and describe them taphonomically, and how to think of scientific questions in the context of deep time, all while discovering new fossils, making new friends, and camping under the Arizona sky.

Description of project leader’s research:

Alex’s research focuses primarily on how vertebrate taphonomy and paleoecology is affected by depositional position within a distributive fluvial system (DFS). By using statistical analyses on vertebrate fossil co-occurrence, she has previously been able to shed light on how Late Triassic paleocommunities surrounding this fluvial megafan may have interacted. This project will supplement those findings with taphonomic and sedimentologic descriptions, in order to determine how fossil assemblages and their preservation styles change based on which DFS subenvironment deposits them. The lab group of Dr. Jason Moore (which includes Alex) has been conducting a companion study on modern animal bones deposited along the Pilcomayo River in Paraguay, allowing correlations to be made with findings in Petrified Forest. With results from both studies, researchers aim to construct a framework for predicting preservation and species occurrence for DFS successions within the fossil record.

Full REC project description:

If you have thought about participating in scientific research but have been hesitant for a variety of reasons, I would love to have you join my group for an introductory dive into Antarctic lakes regardless of seniority, background, major, or preexisting knowledge of the field. My field is geobiology, or the intersection between geology and biology. This includes topics such as how microbes and minerals impact each other, how Earth and life coevolved, how to detect life on other planets using extreme places on Earth that resemble those planets, and much more. Although I have spent time doing most of the above, my current PhD research is based in Lake Fryxell, McMurdo Dry Valleys, East Antarctica. Lake Fryxell is a very unique and extreme environment, covered year-round by 3-5 meters of ice yet home to many microbes that persist even in 24 hours of night in the winter. The McMurdo Dry Valleys overall is Earth’s most Mars-like place. Depending on where you are at coming into the program, you will be learning how to read technical scientific writing in the area of geobiology, notating and interpreting sediment cores from Antarctica, using microscopes to look at minerals from Antarctica, preparing Antarctic sediments for stable isotope analyses, or learning about how to interpret isotope results. During the last week of the program, every student will reflect on their experience with the group via their desired medium (PowerPoint, poster, podcast, essay, etc.) with the potential for presenting to a broader audience as well. My goal is to provide you with a metric for interest in research after the program ends, and to inspire an enthusiasm for geobiology!

Description of project leader’s research:

In the field of geobiology, Shaner looks at sediment cores from Lake Fryxell, Antarctica to decipher past climate and how different variables affect each other. She uses microscopes to look at redox-indicative minerals, which tell her how oxygenated the water was when those minerals were formed and interpret whether they have changed after being buried. She also uses microscopes to look at diatoms—microscopic protists that leave their hard shells preserved—which also indicate oxygenation, as well as lake ice cover thickness. She then observes carbon isotope enrichment as a dependent variable of the above. Does the carbon isotope signature change if minerals have been altered at depth? Does the carbon isotope signature change if the waters are oxic vs anoxic? How does the carbon isotope signature being ‘overprinted’ change our view of using carbon isotopes to interpret past climate? She then applies these questions to broader topics, such as preservation of biological material over longer periods of time.

Full REC project description:

Through this REC Program, students will have the opportunity to see how natural history museums obtain and prepare specimens, learn basic phylogeographic concepts, and gain laboratory and basic bioinformatic skills. The program will start with a brief lecture about the ethics and significance associated with collecting museum voucher specimens. These lectures will outline the responsibility associated with collecting and maintaining specimens and accommodating other researchers' use of museum material through loans and database accessibility for the public. Following this brief introduction, students will tour various divisions within the Museum of Southwestern Biology, particularly the Division of Mammals. Here, I will outline the processes and procedures for creating a holistic voucher specimen. As a precursor to laboratory work, there will be a day dedicated to explaining basic genetic concepts and how we can view biogeographic history through sequencing different parts of genomes. After understanding what is happening from a molecular standpoint, students will get a tour of laboratory equipment, supplies, storage, and safety. Students will then get hands-on experience through a tutorial on how to use single and multi-channel pipettes. The following days will combine laboratory work and guided online research. Students will participate in all steps of DNA extractions, polymerase chain reactions, and cleaning cytochrome b sequences. However, these are lengthy processes with many breaks, so the students will simultaneously learn how to use the Arctos museum database to search for specimens, navigate NCBI GenBank, and learn the functionality of GBIF. To introduce undergraduates to bioinformatics, I will also show them how to use the terminal on their personal computers, the UNM CARC system, R Studio, and some basic programs to create phylogenetic trees.

Required prerequisites:

Since this is program serves as an introduction, students will not be required to have any prior knowledge of the topics discussed. However, students must be interested in viewing and possibly handling museum specimens. This includes but is not limited to skulls, skeletons, tissue, skins, and whole organisms. The Museum of Southwestern Biology practices holistic voucher preparation, which includes various measurements, organ/tissue subsampling, cleaning of skeletal material, creation of study skins, collection of internal/external parasites, and ethanol preservation.

Description of project leader’s research:

Danielle’s research primarily surrounds mammalian genetic diversity both spatially and temporally. Utilizing nuclear and mitochondrial DNA sequences, we can view population expansion, contraction, and colonization events. Often, lineage diversification coincides with changing climate and glacial cycling, which structures genetic variation. To look at these patterns in depth, she studies shrews in Genus Sorex, which are small-bodied mammals notorious for their ability to thrive in multiple environments. Specifically, she looks at 13 species of shrew that range from Europe to the eastern edge of Russia, some of which expand to Alaska and Asian Pacific coastal islands. To investigate the complexity of genetic relationships and past colonization routes, she utilizes single genetic markers and reduced representation whole genome sequencing. From this, Danielle constructs phylogenies and paleodistribution models. The research she does is entirely thanks to collection efforts by natural history museums and international collaborations. Most of her summers are spent doing fieldwork to contribute to museum collections, whether here in New Mexico or going on expeditions to Alaska!

Antarctica is home to various lake systems that can help scientists understand how they have changed since the last ice age. At the depths of each lake, the sedimentary record and the minerals that precipitate from the water column can provide insight into the lake’s hydrology and climate in the past.

Full REC project description:

The McMurdo Dry Valleys (MDV) in Antarctica host several lakes with permanent ice cover year-round, known as perennially ice-covered lakes (PICLs, for short). These systems have been the subject of scientific research for decades in order to understand their hydrology, their microbiology, and the overall geologic and climatic history of the MDV. They also have implications for understanding Martian paleoclimate. The Earth and Planetary Sciences Department at UNM is home to several cores from Lake Fryxell and Lake Joyce aimed at various research goals. In this project, we will ask one simple question: is there a record of environmental change in any of these cores?

To address this, students involved will have hands-on experience in working with these lake cores as we tackle two key components: stratigraphy and chemistry. First, students will apply observational skills to identify any changes in stratigraphy (i.e., are there any differences in sediment size, shape, color, composition?). Secondly, two geochemical techniques will be introduced as a way to familiarize students with analytical methods at a scientist’s disposal and how they can be used to address our research questions. By the end of this project, students will be more comfortable in research practices for future experiences.

Required prerequisites:

Open for STEM majors (Geology, Environmental Science, Biology, Chemistry, etc.), or any student with an interest in earth sciences. No special skills are required.

Preferred prerequisites:

General Chemistry is encouraged but not required.

Number of undergraduate students who will be accepted into this REC project:

Five

Description of project leader’s research:

Giovannetti-Nazario’s research revolves primarily around geochemistry. The geology of Antarctica’s McMurdo Dry Valleys consists of glacial and lacustrine deposits, as well as modern perennially ice-covered lakes. Because lakes with a permanent ice cover are unique to cold arid environments, they involve processes different from glacial or other lake deposits and are capable of providing insight into past climatic conditions. Giovannetti-Nazario will be looking at carbonate facies of two lake systems, modern Lake Fryxell and the paleolake deposits of Miers Valley, to understand how these environments changed over time. Novel geochemical techniques will be used coupled with petrography and facies observations to assess changes in water balance in Lake Fryxell’s past. This work will also help elucidate the paleoclimatic context of Miers Valley where stratigraphic observations, along with stable isotopes and geochronology, will be used to investigate the evolution of Lake Miers since the Last Glacial Maximum.

Full REC project description:

Through the lens of the technology acceptance model, the purpose of this study is to describe the impact of technology innovations in Major League Baseball (MLB) on the satisfaction and commitment to consumption of MLB during in-person and TV viewing experiences. Fans will be surveyed through Amazon Mechanical Turk. To identify moderating factors of technology acceptance of the MLB’s pitch clock, structural equation modeling will be used to examine how technology innovation improves (or diminishes) satisfaction of implementation of the MLB pitch clock during 2023 season; additionally impacting consumption. It is hypothesized that highly identified fans will show high commitment to consuming MLB both in-person and on TV, despite not accepting the new pitch clock technology. Despite an attempt to speed up the pace of play (eliminating down-time between pitches) and add more excitement to the game, MLB pitching technology may not be well received and can diminish in-person and TV consumption of professional baseball. MLB league officials must critically analyze fan attitudes towards new technology before implementation, a result of which can diminish in-person attendance and TV consumption of MLB games.

Full REC project description:

This REC project will give you insights into current multidisciplinary research being conducted at UNM in relation to the Metals Exposure and Toxicity Assessment on Tribal Lands in the Southwest (METALS) Superfund Center funded by a grant from the National Institute of Environmental Health Science. There are thousands of abandoned uranium mines (AUM) throughout the United States, most of which disproportionately impact Native American communities. One of those mines, the Jackpile Mine which operated from 1952-1982, is located only 40 miles from Albuquerque and poses significant environmental and human health risks to the surrounding communities. This site has been designated as a Superfund Site, meaning that it represents one of the most highly contaminated areas in the country—with Pueblo of Laguna (POL) population centers ranging from 0.5-8 miles from the mine. This proximity to the mine site is of major concern when considering windblown contamination, the primary research topic for this REC.

After an initial meeting, where you will become more familiar with Superfund Site, the history of the Jackpile Mine, and what community-based research is, you will attend at least one monthly METALS meeting. At these meetings, you will meet trainees, like me, and research faculty who are working on multiple different projects related to human health, communicating science, water and air contamination, environmental engineering, toxicology, public health, biology, and botany. Most importantly, you will hear from those living at POL and gain a better understanding of the community concerns that the METALS research team is striving to address. A major longstanding concern of the community is the potential for exposure to toxic, windblown metal-bearing dust derived from the mine that may have significant detrimental effects on the health of local communities as a result of inhalation. . Particulate matter, especially particles less than 2.5 microns in size (PM _2.5) can travel deep into the respiratory track and remain in the lung tissue.  Nanoparticulates (less than 100 nm in size) are especially hazardous to human health, because they readily enter the bloodstream, and are transported throughout the body, and can also pass through the blood-brain barrier, causing chronic health conditions. Hearing from members of the POL community is extremely eye-opening and will help you understand the importance of this type of public health research and why this project is being conducted.

Once you understand the purpose of the research, you will then be able to attend a field day. During this field day we will be met by POL Environment and Natural Resources Department (ENRD) Staff members, many of whom live on POL land. ENRD will take us to each of the different mining sites—the main pit, north pit, and south pit. Legacy mining techniques were employed at these sites which included open-pit mining, erodible leftover till, and incomplete clean-up practices. This is extremely dangerous to the environment as it generates large amounts of dust containing heavy metal mixtures that can contaminate the air, water, and soil. Although previously remediated in 1995, continuous erosion for almost three decades has resulted in the exposure of radioactive materials and continues to increase the potential for uranium to be windblown. You will be able to see the extent of the erosion as we travel throughout the mine as well as see an area where exposed ore still exists. Ultrafine dust that comes from these sites becomes extremely mobile in the arid and windy southwestern climate of New Mexico. For that reason, passive air samplers have been set up at each of the mining pit locations which collect windblown dust and dust that settles from the atmosphere. As a result, you will also be participating in collecting these passive air sampler filters and replacing them with new ones since data is being recorded monthly. Please note that proper radiation safety precautions will be taken while we are out in the field.

After going out in the field, you will then learn how to use the Scanning Electron Microscope (SEM), which is an instrument that has the ability to image at a high enough magnification (sub micron) for us to identify and image any airborne uranium particulates that we collect. The SEM uses a scanning electron beam to collect topographical, compositional, structural, and crystallographic information about the specimen of interest. Not only will you learn SEM techniques, but you will also be taught how to find potential uranium-bearing particulate matter from the air filters that we collect out in the field. We will then be able to determine the size, composition of these minerals and if they fall into the category of particulate matter that is easily respirable and a potential threat to the community.

Description of project leader’s research:

The Jackpile Mine, which operated from 1953 to 1982, was located within the tribal lands of the Pueblo of Laguna (POL), was one of the world’s largest uranium (U) mines. This open-pit mine operated by blasting and crushing uranium-bearing rock, and produced a large volume of waste rock from the mining process that was stored on the mine site. These mining activities led to the production and airborne transport of uranium-bearing particulate matter (PM _2.5). PM _2.5 is extremely dangerous to human health because it can travel into the respiratory tract and penetrate the lungs, where it is retained. The Jackpile mine has been designated a Superfund site, meaning that it is currently among the most contaminated places in the United States, and is eligible for federal funds from the EPS Superfund program for remediation. Despite the danger to human health, little is known about the fate and transport of uranium dust, formation mechanisms of U-bearing nanoparticles, pathways of uranium uptake into agricultural crops, human health risks from inhalation or ingestion, or how uranium contaminated mine sites should inevitably be remediated. The proposed research will address a number of questions to help fill this knowledge gap. We plan to (1) systematically sample sites on the POL and at exposed uranium ore outcrops within the Jackpile Mine, (2) analyze air and soil samples for U and other toxic metals through scanning electron microscopy (SEM), transmission electron microscope (TEM) techniques and trace element chemical analysis (ICP-MS), and (3) investigate if agricultural soils are being enriched in U as a result of windblown dust coming from the mine through radiogenic isotopic ratios. The abundance of U-bearing PM _2.5 in the air and soil surrounding the Jackpile Mine will be the baseline to understanding patterns of distribution throughout the Pueblo. This investigation can provide necessary data on how PM is being transported, inhaled, and ingested—potentially explaining pervasive chronic health issues seen in the communities of the Pueblo of Laguna. Empirical data collection is an important step in understanding the interactions that abandoned uranium mines are having on Native American communities, in mitigating the effects of potential exposures to metals, and in improving the overall health of the environment.

The mechanisms of chronic exposure, uptake pathways, whether the Jackpile mine site is producing contemporary U-bearing dust, and the overall human-environmental feedback relationships are yet to be fully understood. Many questions remain regarding the transport, origins, distribution, abundance, and physiochemical characteristics of U-bearing PM associated with AUMs (Lewis et al., 2017). Understanding these characteristics is extremely important to improve the knowledge of how U and other metal-bearing nanoparticles impact the environment and human health. This research is critical because not only does it encourage citizen-based science, but it also promotes relationships, social justice, and collaboration with longed ignored Native American communities. As a result of this research, new scanning electron microscopy (SEM) techniques will be explored and developed, contributing to more accurate mineralogical and geochemical identification of toxic metal-bearing dust. Furthermore, isotopic investigations have yet to be conducted and is necessary to verify if the source of uranium found in the soils at Laguna are coming from the mine. Importantly, these data will address specific concerns raised by community members of the Pueblo of Laguna allowing informed decisions to be made on how to mitigate health risks for those impacted. This project will also serve as a baseline to evaluate how effective planned remediation efforts for the mine, under the auspices of the EPA Superfund project, have been as they are completed over the next several years.

The current R packages for mixed model analysis, such as lme4 and nlme, have limitations that have caused setbacks in research and have hindered the ability to conduct analyses effectively.

Description of project leader’s research:

Sina’s focuses on how the risk of COVID-19 infection varied across different counties in the United States during the pandemic, and how the CDC's community risk level metrics were used to estimate this risk. These metrics helped guide decisions on infection prevention strategies. The CDC categorized counties into low, medium, or high risk based on factors like new cases, hospital admissions, and bed use. These risk levels determined actions like testing, isolation, masking, and vaccination.

The study aimed to understand how consistent these risk level assignments were over time and whether they changed frequently. To do this, you gathered data on COVID-19 cases, hospitalizations, and bed occupancy from public sources. You analyzed how often counties' risk levels stayed the same or changed, and you looked at the speed of these changes. Additionally, you explored how the rate of risk level change related to factors like county population size, urbanization level, and the number of hospitals.

In this research, Sina also compared the CDC's metrics with an alternative metric that predicts risk similarly. This alternative metric adjusted the threshold for hospital bed occupancy to 5% instead of 10%.
