Perceptions Of Trail Safety In Humboldt County, California: An Analysis Of Safety Concerns, Factors That Impact Trail Use, And The Value People Place On Trails, Natalie C. Arroyo

Cal Poly Humboldt theses and projects

Trails in Humboldt County, California that are used for both transportation and recreation have myriad community benefits. However, people’s concerns about feeling safe can affect trail use, design, and development, as well as how trails are valued and perceived by residents. There has been a lack of information in Humboldt County about trail safety perceptions despite it being a factor that repeatedly arises in infrastructure planning and funding conversations. My research was focused on answering the following questions: (1) How do Humboldt County trail users perceive their safety on and near trails? (2) What factors affect these perceptions about safety, …

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 …

Bottle With A Message: The Role Of Story Writing As An Engagement Tool To Explore Children's Perceptions Of Marine Plastic Litter, Estelle Praet, Jostein Baeza-Álvarez, Veer D De, Geraldine Holtmann-Ahumada, Jen S. Jones, Sarah Langford, Jessica Michel Dearte, John Schofield, Martin Thiel, Kayleigh J. Wyles

School of Psychology

As human behaviors play a crucial role in addressing the global threat of plastic pollution, it is vital to understand perceptions about marine plastic litter (MPL) and to develop interventions encouraging pro-environmental behaviors (PEBs). This study evaluates story writing as a window to explore perceptions and as an engagement activity to boost PEBs. During the COVID-19 lockdowns, schoolchildren from the East Pacific coast participated in this activity, each creating a story and answering a pre-post survey. Qualitative and quantitative analysis of 81 stories and 79 surveys show awareness of sources and impacts. Participants identified land and local pollution as significant …

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 …

Applications Of Urban Land Evaluation And Site Assessment (Ulesa) In Chesterfield County, Virginia, Emily Hastings

Theses and Dissertations

Urban and suburban agriculture is increasing in popularity across the United States. However, many of these farms are short-lived due to a combination of human factors (e.g., managerial, economic, cultural) and environmental or spatial factors (e.g., zoning, soil quality, distance to markets). Geospatial analysis, in the form of suitability modeling, could aid in locating suitable sites for these activities. Land Evaluation and Site Assessment (LESA) is a suitability modeling technique that generates a score for agricultural land use in traditionally rural spaces. This research explores adapting this method to encompass the complexities of placing diverse, in-ground agriculture in urban and …

Toxic Timescapes: Examining Toxicity Across Time And Space, Simone M. Müller, May-Brith Ohman Nielsen

Ohio University Press Open Access Books

An interdisciplinary environmental humanities volume that explores human-environment relationships on our permanently polluted planet.

While toxicity and pollution are ever present in modern daily life, politicians, juridical systems, media outlets, scholars, and the public alike show great difficulty in detecting, defining, monitoring, or generally coming to terms with them. This volume’s contributors argue that the source of this difficulty lies in the struggle to make sense of the intersecting temporal and spatial scales working on the human and more-than-human body, while continuing to acknowledge race, class, and gender in terms of global environmental justice and social inequality.

The term toxic …

Using State Law Before The Glaciers Thaw: Climate Torts After Bp V. Baltimore, Jillian Mayer

American University Journal of Gender, Social Policy & the Law

We are living in the beginning stages of Earth’s sixth mass extinction. Since the Industrial Revolution of the nineteenth century, the burning of fossil fuels has released huge quantities of carbon dioxide and other greenhouse gasses (“GHGs”) into the atmosphere. The increased concentration of GHGs causes the atmosphere to retain more heat. Consequently, ecosystems and weather patterns shift and change faster than most plants, animals, and human societies can adapt. Climate change threatens global peace, crashes economies, and creates humanitarian crises.

The Walls At The Ends Of Empires: Towards A Political Ecology Of The Imperial Border, Benjamin Allen Stahnke

Antioch University Dissertations & Theses

This dissertation study investigates the intricate and complicated interplay between the border walls of imperial states, environmental change, and dispossession. Employing a multidisciplinary approach rooted in Political Ecology, and drawing on the theoretical frameworks of Social Metabolism, Social Kinetics, and Green History, the study is built around an analysis of two historical examples: the Roman border walls in the north of England (Hadrian’s Wall and the Antonine Wall), and the U.S.-Mexico border wall. The research uncovers two overarching conclusions: firstly, imperial border walls serve as discriminatory structures, targeting and segregating Indigenous populations while asserting control over Indigenous geographies; secondly, the …

Diving To New Depths: An Exploration Of Aquarium Visitors' Reflection At A Shark Exhibit, Nicole Leigh Conklin

Antioch University Dissertations & Theses

Zoos and aquariums (Z/As) are conservation-oriented free-choice learning institutions. In order to support their mission of advancing wildlife conservation, Z/As deliberately design opportunities and experiences to meaningfully engage visitors in understanding, caring for, and acting on behalf of exhibited species. Conservation psychologists and practitioners have applied values-based and models of human behavior to design and evaluate experiences aimed to influence myriad cognitive, affective, and behavioral outcomes. However, there is little research exploring the role of and opportunity for reflection within these institutions. Models of reflection and reflective practice, which are rooted in both theory and empirical data, stress the importance …

The Use Of A Habitat Quality Stress Index To Evaluate Stress As An Analog For Proximate Fitness In The American Crow Within A Matrix Of Landcover Characteristics To Assess Its Potential Contribution To Disease Etiologies, Theodore Lee Grabarz

Antioch University Dissertations & Theses

All organisms occur within spatial and temporal environments to maximize proximate fitness (health) and thus life history outcomes. Previous work has examined the temporal and behavioral aspects of proximate fitness on life history outcomes particularly regarding highly perturbed environments (i.e., climate and land use change, resource extraction, agricultural erosion, etc.). My work focuses on the less examined spatial aspect of these perturbed environments. More specifically, this dissertation examines habitat selection and quality as the basis for understanding stress response (negative and positive feedback mechanisms) to environmental stressors within the larger context of regional or gamma (ɣ) biodiversity. Through the lens …

Effects Of Management And Environmental Variables On Ant Richness, Diversity, And Nest Abundance In Pitch Pine-Scrub Oak Barrens, Heathlands, And Dry Rocky-Ridge Communities In Inland Massachusetts, Usa, Kyle Bradford

Antioch University Dissertations & Theses

Heathlands and pitch pine-scrub oak (PPSO) barrens are globally-imperiled natural communities threatened by human development and disruption of natural disturbance regimes. To restore these habitats in the northeastern United States, many sites are managed by mechanical tree harvesting, mowing, selective herbicide, and prescribed fire. Restored PPSO barrens and heathlands are important habitat for rare and threatened biota; barrens habitat has been shown to support high ant diversity including rare and threatened species. Ants are important providers of ecosystem services and functions, yet their ecology and response to management in inland Massachusetts barrens are not well known. I used hand-sampling to …

Focusing on the federal regulatory permitting process, the study aims to understand its impact on LSER projects and proposes the application of adaptive regulation for improvement. Employing Q methodology, participants expressed their views on 34 statements related to wetland permitting for LSER projects. Factor analysis revealed two distinct perspectives: Factor 1 emphasizes the reorganization of the permitting process within existing regulations, advocating for more documentation and structured processes. Factor 2 highlights the need for restructuring both the permitting process …

Artistic Engagement With Monadnock: A Hermeneutic Phenomenological Study, Jonathan W. Coffin

Antioch University Dissertations & Theses

This hermeneutic phenomenological study discloses the lived experience of creating art in association with New Hampshire’s Mount Monadnock. This study reveals the potential for artistic invention in association with place gradually to undermine an established sense of separation from environment and to prompt conscious awareness of continuity with environment. A series of interviews with four artists who create art of or in the presence of Monadnock revealed in the lived experience of creating Monadnock art a process that consists of five phases: first encounter, abstract appreciation, existential understanding, sustained attention, and continuity. A hermeneutic circular method of interpretation based upon …

Connecting Antibiotic Resistance To The Environment (Care): Introducing A Novel Framework Integrating Chemical Cross-Resistance And Place-Based Engagement To The Blue Marsh Watershed In Reading, Pennsylvania, Jill Felker

Antioch University Dissertations & Theses

Antibiotic resistance is a serious health threat around the world. Millions of individuals are infected with antibiotic-resistant bacteria yearly, and thousands die from previously curable illnesses. Although antibiotic resistance occurs naturally, misuse of antibiotics accelerates the loss of their effectiveness. Public health campaigns focusing on antibiotic awareness have not effectively communicated and educated the public on this health crisis. New efforts to combat antibiotic resistance are urgently needed. This dissertation focuses on the ecological and public health components of antibiotic resistance research that must be addressed to decelerate antibiotic resistance. A new interdisciplinary theoretical framework was developed to Connect Antibiotic …

Land Reform In Sub-Saharan Africa: Exploring Interested Parties Perspectives On Cameroon's Land Tenure And Land Law Reform, Jacques Kenjio

Antioch University Dissertations & Theses

This research study seeks to understand interested parties’ perspectives on Cameroon's existing land tenure systems, the 1974 land law, and ongoing efforts to reform this land law. It identifies both concerns and specific recommendations from these parties on the formulation and implementation of future reforms. In the decades following the achievement of independence from European colonizers, most governments in sub-Saharan Africa (SSA) have adopted new national land tenure policies to meet their countries’ needs and aspirations. In some parts of SSA, however, this process of land tenure formalization has negatively impacted the land rights of people observing customary land tenure. …

A Mental Health Professional Opinion On Family Involvement During The Treatment Of Severe Mental Illness: A Multiple Case Study, Vanessa Perocier

Antioch University Dissertations & Theses

While severe mental illness (SMI) is extensively studied, less attention focuses on the relationship between people with SMI and their families and the impact this may have on treatment. Bronfenbrenner's (1979) ecological systems theory conceptualized the treatment and recovery of people with SMI and their families. This study proposes that if family members getting social support contribute to a person's treatment plan, the individual's treatment outcome will improve rather than the individual enduring the treatment process individually. By applying ecological systems theory, mental health professionals and policymakers can better grasp the systemic nature of individuals, their family members, and surrounding …

Children Tell Landscape-Lore Among Perceptions Of Place: Relating Ecocultural Digital Stories In A Conscientizing/Decolonizing Exploration, Meredith Jean Bird Miller

Antioch University Dissertations & Theses

We know that when children feel a sense-of-relation within local natural environments, they are more prone to feel concern for them, while nurturing well-being and resilience in themselves and in lands/waters they inhabit. Positive environmental behaviors often follow into adulthood. Our human capacities for creating sustainable solutions in response to growing repercussions of global warming and climate change may grow if more children feel a sense of belonging in the wild natural world. As educators, if we listen to and learn from students’ voices about how they engage in nature, we can create pedagogical experiences directly relevant to their lives. …

Quantifying The Potential Health Impacts Of Unvented Combustion In Homes – A Meta- Analysis, P. Jacob Bueno De Mesquita, Nuria Casquero-Modrego, Iain Walker, Brennan D. Less, Brett C. Singer

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 …

More Than Mindfulness: The Effectiveness Of An Ecospiritual Fellowship In Building Connection, Promoting Wellness, And Transforming The Ecological Worldviews Of Teachers, Medora West Willmore

Antioch University Dissertations & Theses

Action towards planetary well-being requires more than environmental awareness, acquisition of knowledge, or technological fixes; it necessitates a sacred connection, recognizing interdependence, and an ethic that maintains dignity for all non-human beings. It requires a shift in our ecological consciousness from the dominator and exploitative (I-it) view to the connected and participatory (I-thou) view which is best facilitated by an emerging paradigm called ecospirituality. For the next generation to adopt this paradigm, teachers must first adopt it. The research goal was to to transform teachers’ relationship with the natural world by enlisting ecospirituality as central in supporting teacher wellness, as …

The Environmental Cellular Stress Response: The Intertidal As A Multistressor Model, Michael Collins, Melody S. Clark, Manuela Truebano

School of Biological and Marine Sciences

The wild poses a multifaceted challenge to the maintenance of cellular function. Therefore, a multistressor approach is essential to predict the cellular mechanisms which promote homeostasis and underpin whole-organism tolerance. The intertidal zone is particularly dynamic, and thus, its inhabitants provide excellent models to assess mechanisms underpinning multistressor tolerance. Here, we critically review our current understanding of the regulation of the cellular stress response (CSR) under multiple abiotic stressors in intertidal organisms and consider to what extent a multistressor approach brings us closer to understanding responses in the wild. The function of the CSR has been well documented in laboratory …

Entrainment And Horizontal Atmospheric Transport Of Microplastics From Soil, Sajjad Abbasi, Mahrooz Rezaei, Monireh Mina, Abdolmajid Sameni, Patryk Oleszczuk, Andrew Turner, Coen Ritsema

School of Geography, Earth and Environmental Sciences

Soils are an important source of microplastics (MPs) to the atmosphere but the fluxes and mechanisms involved in MPs entrainment are not well understood. In the present study, a series of horizontally aligned sediment traps have been deployed at different heights within 1 m above the ground for a two-month period at various locations in an arid region (Sarakhs, Iran). MPs were isolated from sediments and were quantified and characterised according to size, colour, shape and polymer composition by established techniques. Most MPs were <250 μm in length, fibres were the most important shape, black and blue-green were the dominant colours, and polymer abundance decreased in the order polyethylene > nylon > polypropylene > polystyrene > polyethylene terephthalate. The distributions of sediment mass (range <0.01–9 g) and number of MPs (range = 0 to 21) were heterogeneous, both between sites and at the different heights sampled, and yielded median, vertically-averaged horizontal fluxes for the region of about 450 g m−2 d−1 and 2600 MP m−2 d−1, respectively. However, when data were pooled, the number of MPs normalised to sediment mass exhibited a significant inverse relationship with sediment mass, an effect attributed to the presence of ambient suspended MPs and sediment that are diluted by the suspension of soil and deposited MPs at higher wind speeds. The mechanisms of MP saltation and entrainment were not ascertained but a theoretical framework for threshold shear velocity based on regularly-shaped particles and density considerations is presented. Further experimental work is required to verify this framework, and in particular for fibrous MPs with different aerodynamic properties to soil particles.

Smart utilities comprise an important aspect of modern smart cities. The aim of this work is to present a case study for implementing a solar- energy-based electric vehicle charging station (for the first time on a campus in Egypt) at the British University in Egypt. The total amount of energy needed for charging each electric vehicle (EV) was estimated to be 13.3—16.2 kWh. The EV is operated by 12 batteries. The station was designed to provide energy sufficient for charging up to two vehicles daily during summer. Thus, the station sizing was based on the provision of 16.2 KW and …

Spatial Robustness: Double-Design And The Democratization Of Space, An Exploration Of Designing For Multiple Uses, Michael Cassidy

School of Art, Design and Architecture Theses

Spatial Robustness: Double-design And The Democratization Of Space, An Exploration Of Designing For Multiple Uses by Michael Warren Arkinstall Cassidy Differing attitudes to the expected life and value of architecture characterize the sustainability debate, yet space itself is rarely mentioned. The buildings for which architecture is responsible comprise both space and materials. While it is taken for granted that some existing buildings can be reused productively, this cultural phenomenon has not influenced the design of the new stock. While content to revere old buildings, the qualities that make them valued have not influenced design principles for new projects. Should new …

Impacts Of Polyethylene Microplastics On The Microalga, Spirulina (Arthrospira Platensis), Sajjad Abbasi, Sahar Amiranipour, Javad Karimi, Sasan Mohsenzadeh, Andrew Turner

School of Geography, Earth and Environmental Sciences

Microalgae play a critical role in the food web and biogeochemical cycling and produce compounds that are commercially exploited. However, their reactions and responses to microplastic contamination are not well understood. In this study, the widely distributed and commercially important cyanobacterium, Spirulina (Arthrospira platensis), was exposed to different concentrations (1–100 mg L−1) of low-density polyethylene microplastics (<5 μm) over a 20-d period. Various end-points were combined with different microscopic techniques in order to examine physiological and biochemical effects and interactions between the plastic and microalga. Growth rate and photosynthetic activity decreased with increasing microplastic concentration, and a maximum inhibition ratio of about 9% was calculated from optical density measurements. Plastic concentrations above 10 mg L−1 resulted in oxidative stress and the intracellular production of proline. Fragmentation and swelling of trichomes and attachment of microplastics was observed in the exposures, and microplastics appeared to adhere or aggregate around fragmented or fragmenting regions. The latter effect may indicate trichome weakening by microplastics or their concentration around cytosolic debris; nevertheless, it provides a potential mechanism for internalisation of small particles. Although unrealistically high concentrations of well-defined microplastics have been employed, relatively small disruptions at the population level incurred by lower concentrations could have more serious implications for ecosystem services and functioning.

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 …

Assessing The Risk Of Acute Gastrointestinal Illness Attributable To Three Enteric Pathogens From Contaminated Private Water Wells In Ontario, Tessa Latchmore, Paul Hynds, R. Stephen Brown, Kevin Mcdermott, Anna Majury

Articles

The province of Ontario compromises the largest groundwater reliant population in Canada serving approximately 1.6 million individuals. Unlike municipal water systems, private well water is not required to meet water quality regulatory standards and thus source maintenance, treatment and testing remains the responsibility of the well owner. Infections associated with private drinking water systems are rarely documented given their typically sporadic nature, thus the human health effects (e.g., acute gastrointestinal illness (AGI)) on consumers remains relatively unknown, representing a significant gap in water safety management. The current study sought to quantify the risk of waterborne AGI attributed to Giardia, shiga-toxin …
