Temporal, Phenotypic, And Quantitative Characterization Of Thyroid Infiltrating Mononuclear Cells During Development Of Spontaneous Autoimmune Thyroiditis In Obese Strain Chickens, Katelyn M. Clark, Chrysta N. Beck, Gisela F. Erf

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The Obese strain (OS) of chickens spontaneously develops autoimmune thyroiditis (SAT) and is a well-established biomedical model for Hashimoto’s thyroiditis in humans. Both conditions are characterized by the infiltration of thyroid glands with mononuclear immune cells resulting in the destruction of thyroid tissue and impairment of the thyroid’s endocrinological functions. Past studies described immune cell infiltration in thyroids of the OS chickens, but the time-course, cell composition, and relative amounts of the various immune cells infiltrating the thyroids have not been well defined. In this project, frozen and stored thyroid glands that were previously collected at 1, 4, 7, 14, …

Middle Savannah River: An A/R/Tographic Ecopedagogical Ethnography Experimenting With Rhizomatic Perspectives, Lisa Augustine-Chizmar

College of Graduate Studies: Theses & Dissertations

This research is an experiment in perspective. Using the four commonplaces (Schwab, 1978), I practiced letting the Savannah River teach me what there is to know about the water, the land, the people, and the other entities that depend on ki through artistic, ethnographic, and ecopedagogical lenses. The ethnographic findings describe the social actors that depend on ki and give a voice to the River. The a/r/tographic findings display the River on a canvas map through two hundred years using paint, clay, photography, video, abstract acrylics, and fabric. Together, these methods contribute to a unique ecopedagogical journey. This word cloud …

This manuscript summarizes a recent survey-based effort to estimate wild pig damage and control costs incurred by livestock producers by state and livestock type. The survey was distributed by the U.S. Department of Agriculture National Agricultural Statistical Service in the summer of 2021 to a sample of livestock producers in the 13-state region. Findings …

Building A Macrosystems Ecology Framework To Identify Links Between Environmental And Human Health, Felisha N. Walls

Theses and Dissertations

The structure and functions of natural systems continue to be degraded by human activities such as land-use change. One potential consequence that has received relatively little attention is a corresponding decline in human health. Altered ecosystems can present a host of risks to human health. Yet the consequences of environmental degradation are rarely considered in national-scale research on human well-being. The guiding objective of this work is to compare stream health and socioeconomic metrics with spatially congruent human health metrics throughout the conterminous United States, then to identify potential links between environmental health, socioeconomic factors and human health. Environmental health …

Assessing The Knowledge On Sustainability And Barriers To Daily Sustainable Practices Among Faculty And Students In Higher Education: The Case Of Eastern Illinois University, Joel Edem Holison

Masters Theses

The concept of sustainable development gained prominence with the publication of the Brundtland Report, which emphasized economic progress without jeopardizing future generations' well-being. Following that, the Education for Sustainability (EfS) program was created by the United Nations to raise sustainability awareness. However, the transition to sustainable living is fraught with difficulties, including a lack of knowledge, financial constraints, infrastructure gaps, and political ideologies. This study focuses on sustainable practices among Eastern Illinois University (EIU) students and faculty, as well as the barriers to daily sustainable behaviors. As independent variables influencing sustainable practices, the study evaluates sustainability knowledge/awareness, personal financial situation, …

Eating Change: A Critical Autoethnography Of Community Gardening And Social Identity, Jessica Gerrior

Antioch University Dissertations & Theses

Community gardening efforts often carry a social purpose, such as building climate resilience, alleviating hunger, or promoting food justice. Meanwhile, the identities and motivations of community gardeners reflect both personal stories and broader social narratives. The involvement of universities in community gardening projects introduces an additional dimension of power and privilege that is underexplored in scholarly literature. This research uses critical autoethnography to explore the relationship of community gardening and social identity. Guided by Chang (2008) and Anderson and Glass-Coffin (2013), a systematic, reflexive process of meaning-making was used to compose three autoethnographic accounts. Each autoethnography draws on the author’s …

A Comprehensive Satellite-Based Assessment Across The Pacific Arctic Distributed Biological Observatory Shows Widespread Late-Season Sea Surface Warming And Sea Ice Declines With Significant Influences On Primary Productivity, Karen E. Frey, Josefino C. Comiso, Larry V. Stock, Luisa N C Young, Lee W. Cooper, Jacqueline M. Grebmeier

Geography

Massive declines in sea ice cover and widespread warming seawaters across the Pacific Arctic region over the past several decades have resulted in profound shifts in marine ecosystems that have cascaded throughout all trophic levels. The Distributed Biological Observatory (DBO) provides sampling infrastructure for a latitudinal gradient of biological "hotspot" regions across the Pacific Arctic region, with eight sites spanning the northern Bering, Chukchi, and Beaufort Seas. The purpose of this study is two-fold: (a) to provide an assessment of satellite-based environmental variables for the eight DBO sites (including sea surface temperature (SST), sea ice concentration, annual sea ice persistence …

Conceptualizing The Construct Of Ocean Identity, Miriah R. Kelly, Jo-Marie Kasinak, Emma Mckinley, Caitlin Mclaughlin, Jamie M.P. Vaudrey, Jennifer Mattei

Biology Faculty Publications

The construct of ocean identity provides a valuable lens that can unpack the multiple dimensions of human connections with ocean spaces, and crucially places importance on the integration of cognitive, affective, and behavioral components. The construct of ocean identity is applicable in academic and professional contexts, and is largely unexplored from both qualitative and quantitative research perspectives. This comment article presents a revised definition of ocean identity and posits a useful conceptual framework based on a robust analysis of literature to unveil the multiple dimensions that may explain an individuals’ ocean identity. Here we identify a series of attributes that …

Analyzing Residential Curbside Collection For Food Waste In Humboldt County, Yvette Lindler

Cal Poly Humboldt theses and projects

The most prevalent material in the California landfill-destined solid waste stream is food. Food waste is not only an economic and social concern, but a significant environmental challenge as well. Most food waste is disposed of in landfills, where it anaerobically decomposes and releases methane, an extremely potent greenhouse gas and driver of climate change. Policies passed in California, including AB 1826 and SB 1383, aim to implement organic waste recycling programs and reduce methane emissions by diverting organic waste from landfills. The technology to process this food waste exists, but these facilities are limited or nonexistent in rural areas …

Technical And Economic Feasibility Of A Microgrid For A Fire Station In Humboldt County, California., Nishaant Kumar Sinha

Cal Poly Humboldt theses and projects

Microgrids are emerging as a promising solution to unreliable grid energy. Today, California is not only witnessing grid resiliency challenges from natural disasters such as wildfires, earthquakes, floods and heatwaves, but it is also seeking to green the grid and bring more renewables online. For example, Humboldt County, where this project is focused, has recently experienced an earthquake of 6.4M (on December 22nd, 2022), which shut down the regional grid for ~20 hours.

Microgrid adoption enables critical facilities to operate seamlessly. The Humboldt Bay Fire Station (HBFS) No.1 is one such example, where first responders work to protect citizens against …

Information And Communications Technology Within Coastal Resilience Frameworks: A Multi-Phase Model To Guide Cross-Sector Planning, Ren-Neasha Blake Gilmore, Wie Yusuf

College of Business (Strome) Posters

This research examines how information and communications technology (ICT) has bolstered coastal resilience efforts across multiple sectors in coastal areas. Coastal vulnerability can be considered a wicked problem in society. Wicked problems are hard to define and solve and have broad social, economic, and environmental impacts. When dealing with wicked problems, planners have no right to be wrong since the outcomes can be detrimental and far-reaching. A closer look at coastal areas like those in coastal Virginia and the Caribbean highlights the constant need for policy and strategy toward feasible resilience solutions. Cross-sector partnerships and cross-disciplinary efforts are proven effective …

Emotions And Perceptions Surrounding Teaching Climate Change In The United States: Results From A Teacher Survey, Susan Clayton, Angeline Sangalang, Rebecca Anderson

All Faculty Articles

Children are worried about climate change. Educational settings provide an opportunity to provide coping resources, but teachers do not always feel comfortable doing so. One reason for hesitancy may be their own negative emotions. This paper describes findings from a survey of Action for the Climate Emergency (ACE)’s teacher network, looking at teachers’ perceptions and emotions about climate change, as well as their experiences in teaching climate-related topics. Teachers had both positive and negative responses to climate change; motivation and compassion along with frustration and sadness were the four most common emotional responses. They also generally felt supported in their …

Arts & Sciences Faculty Publications

While a growing body of scientific literature describes the population health impacts of fossil fuel production and burning via climate and air pollution pathways, less is known about the health impacts of indoor combustion. This paper summarizes the results of studies from the last two decades that investigated the association between exposure to sources of unvented combustion pollutants in homes and a range of health outcomes. We found gas combustion to be associated with 6-28% (95% confidence intervals) increased odds of asthma symptoms, 4-51% increased odds of systemic symptoms, 7-81% increased odds of asthma medication use, and 3-12% increased risk …

Preface : Fruit And Vegetable Waste Utilization And Sustainability, Sachin A. Mandavgane, Ipsita Chakravarty, Amit Jaiswal

Books/Book Chapters

Fruits and vegetables are an important source of nutrition and a key element of a healthy balanced diet. Several organizations such as the World Health Organization (WHO), Food and Agriculture Organization of United Nations (FAO), and Food Health England suggest consuming more than 400 g of fruits and vegetables per day (roughly five portions per day) to improve overall health and reduce the risk of certain cardiovascular diseases and cancer; subsequently, consumption and production of fruits and vegetables are on the rise. The increased consumption/production of fruits and vegetables has resulted in huge quantities of waste (approximately 42% of the …
