Association Between Historical Neighborhood Redlining And Cardiovascular Outcomes Among Us Veterans With Atherosclerotic Cardiovascular Diseases, Salil V Deo, Issam Motairek, Khurram Nasir, Amgad Mentias, Yakov Elgudin, Salim S Virani, Sanjay Rajagopalan, Sadeer Al-Kindi

Faculty, Staff and Students Publications

Importance: In the 1930s, the government-sponsored Home Owners' Loan Corporation (HOLC) established maps of US neighborhoods that identified mortgage risk (grade A [green] characterizing lowest-risk neighborhoods in the US through mechanisms that transcend traditional risk factors to grade D [red] characterizing highest risk). This practice led to disinvestments and segregation in neighborhoods considered redlined. Very few studies have targeted whether there is an association between redlining and cardiovascular disease.

Objective: To evaluate whether redlining is associated with adverse cardiovascular outcomes in US veterans.

Design, setting, and participants: In this longitudinal cohort study, US veterans were followed up (January 1, 2016, …

The Association Of Sex Ratio On Suicide Rates In United States Counties: An Exploration Of Mechanisms, Kristin Snopkowski, Hallie Turner

Anthropology Faculty Publications and Presentations

Researchers have long puzzled over suicidal behavior. In this paper, we posit that when people are unable to attract mates given unfavorable sex ratios, suicide rates increase. Sex ratio, the proportion of males in a population, is linked to a variety of behaviors, including marriage stability, violence, depression, and infidelity. We test whether suicide rates are associated with county-level sex ratios utilizing data from 1999 to 2018, controlling for a variety of factors known to be associated with suicide risk. We find that sex ratio is associated with suicide rates, where a greater proportion of males in a county (age …

Left Inferior Frontal Gyrus Connectivity With The Dorsomedial Subsystem Of Default Network Tracks Real-World Conversation Behaviour, Dhaval M. Bhatt

Dartmouth College Master’s Theses

Social interactions are multifaceted, complex, and critical to social behaviour as they help gather information, develop social connections, and regulate social behaviour (Lakey & Orehek, 2011; Testard et al., 2021; Jolly & Chang, 2021). Among social interactions, conversations find a special place for humans due to the nuances associated with language, conversational behaviour (e.g., gestures), and context (e.g., where conversations occur and what is discussed). Researchers have studied aspects of single conversation behaviour, content related to conversations, and brain function (Sievers et al., 2020). However, little is known about the brain function of densely-sampled in-person conversation behaviour. Filling this gap …

Assessing Monkeyface Prickleback Cebidichthys Violaceus As An Emerging Aquaculture Species In California, Matthew Hoehn

Capstone Projects and Master's Theses

In the context of global seafood demand and the pressing need for sustainable aquaculture practices, identifying and developing new species for aquaculture is of paramount importance. This study provides a comprehensive analysis of the reproductive behavior and embryological development of the monkeyface prickleback (Cebidichthys violaceus), an emerging aquaculture species in California. The species exhibits several desirable traits for aquaculture, including herbivory, sedentary behavior, high tolerance to environmental extremes, high fillet-to-carcass ratios, and product similarity to high-value, less sustainable fishes such as unagi. Since very little reproductive behavior was available at the start of these studies the experiments were designed on …

Feeding Habits And Diet Composition Of The African Sacred Ibis In Selected Water-Logged Sites In Dar Es Salaam, Tanzania, Jared S. Bakuza, Joyce Ndinadyo

Tanzania Journal of Science

The African Sacred Ibises Threskiornis aethiopicus are generalist birds that feed on many invertebrates and some vertebrates. However, the diet composition of local T. aethiopicus populations in wetland areas in Dar es Salaam Tanzania was unknown. Sacred Ibises from eight water-logged areas in Dar es Salaam City, Tanzania were studied to determine their feeding habits and diet composition using direct observations and molecular analysis of faecal samples. Snails species identified from sites frequented by T. aethiopicus included Lymnaea natalensis (61.62%), Melanoides tuberculatus (20.64%), Bulinus sp. (17.66%) and Anisus sp. (0.08%), while molecular analysis of the birds’ diet revealed presence of …

Revisiting Great Basin Bristlecone Pine (Pinus Longaeva) In The Stansbury Mountains, Utah, David R. Burchfield, Otto W. De Groff, Matthew F. Bekker, Stanley G. Kitchen, Steven L. Petersen

Western North American Naturalist

Great Basin bristlecone pine (Pinus longaeva D.K. Bailey) presence in the Stansbury Mountains of north-central Utah has been reported prior to the year 2020, but these reports lack adequate population characterization and the delineation of distinct stands of trees. In summer 2020, we identified and documented the presence of 5 separate stands of bristlecone pine in the Stansbury Mountains. These stands are removed from the nearest bristlecone populations in other mountain ranges by a distance of approximately 120 km; as such, they represent a unique outlier population of the species. We used GPS data to create a geographic information …

Ecology And Retribution: Blake, Tokarczuk, And Animal Rights, Kristina Isaak Powell

Theses and Dissertations

This thesis explores how Nobel laureate Olga Tokarczuk's 2008 novel, Drive Your Plow Over the Bones of the Dead, engages with William Blake's life and his writings on animal welfare and speaks to current conversations about multispecies justice in the environmental humanities. It argues, first, that in recognizing how this novel's protagonist, Janina, selectively reads Blake to rationalize retributive justice, readers should resist a tendency to mistake this character for Tokarczuk's ideal advocate for environmental ethics. Secondly, it asserts that legal scholars' division between retributive and restorative justice offers valuable framework for approaching both this novel and ongoing debates about …

Nutrient-Rich Submarine Groundwater Discharge Increases Algal Carbon Uptake In A Tropical Reef Ecosystem, Florybeth Flores La Valle, Julian M. Jacobs, Florence I. Thomas, Craig E. Nelson

All Faculty Open Access Publications

Submarine groundwater discharge (SGD) in high volcanic islands can be an important source of freshwater and nutrients to coral reefs. High inorganic nutrient content is generally thought to augment primary production in coastal systems but when this is delivered via a freshwater vector as is the case with SGD in this study, the effects on productivity are unclear. In the current literature, there is limited evidence for a direct association between SGD and primary productivity of reefs. To elucidate the response of primary productivity to SGD, we conducted spatially and temporally explicit in situ benthic chamber experiments on a reef …

Development Of A Ddpcr Multiplex To Measure The Immune Response To Borrelia Burgdorferi., Kailey Marie Mccain

USF Tampa Graduate Theses and Dissertations

Zoonotic diseases account for a significant proportion of emerging infectious diseases (EIDs), with their dynamics being heavily influenced by the environment. While the effects of the environment on population-level disease dynamics have been extensively studied, there is limited research investigating the impact of the environment on individual-level disease susceptibility and transmission. This study aims to fill this gap by creating a tool to examine the variation in immune response to Borrelia burgdorferi, the causative agent of Lyme Disease, in two competent host species, Peromyscus leucopus and Peromyscus maniculatus. Two triplex droplet digital polymerase chain reaction (ddPCR) assays were developed to …

A Study In Cuba Of The Biology, Ecology And Agroecological Management Of Heteropsylla Cubana Crawford In Leucaena Leucocephala (Lam.) De Wit, N. Valenciaga, M. Felicia Díaz, T. E. Ruíz, M. Fernández, C. Mora

IGC Proceedings (1977-2023)

As a consequence of the increase in Leucaena leucocephala areas to counter the shortage of feed in Cuban cattle production, there is a risk of the development of Heteropsylla cubana Crawford (Hemiptera: Psyllidae) as a pest in silvopastoral systems with this legume. This psyllid is known to be the main phytophagous pest (Valenciaga, 2003), which produces damage in 95% of the apical region of branches. Since information on the identification and biology of a pest species is a necessary prerequisite for its management, a taxonomic, biological and ecological study was conducted to define Heteropsylla behaviour in Cuban conditions and elaborate …

Patterns Of Species Richness And Turnover In Endemic Amphibians Of The Guineo-Congolian Rainforest., Lotanna M. Nneji, Josué A.R. Azevedo, Oyetola O. Oyebanji, Liang Ma, Paul R. Elsen, Gabriel Salako, Robert Puschendorf, Robert M. Pringle

School of Biological and Marine Sciences

Aim: The African Guineo-Congolian (GC) region is a global biodiversity hotspot with high species endemism, bioclimatic heterogeneity, complex landscape features, and multiple biogeographic barriers. Bioclimatic and geographic variables influence global patterns of species richness and endemism, but their relative importance varies across taxa and regions and is poorly understood for many faunas. Here, we test the hypoth-esis that turnover in endemic amphibians of the GC biodiversity hotspot is influenced mainly by the geographic distance between grid cells and secondarily by rainfall- and temperature- related variables.Location: West and Central Africa.Major Taxa Studied: Amphibians.Methods: We compiled species-occurrence records via field sampling, online …

The Association Between Drought Exposure And Respiratory-Related Mortality In The United States From 2000 To 2018, Yeongjin Gwon, Yuanyuan Ji, Jesse E. Bell, Azar M. Abadi, Jesse D. Berman, Austin Rau, Ronald D. Leeper, Jared Rennie

Daugherty Water for Food Global Institute: Faculty Publications

Climate change has brought increasing attention to the assessment of health risks associated with climate and extreme events. Drought is a complex climate phenomenon that has been increasing in frequency and severity both locally and globally due to climate change. However, the health risks of drought are often overlooked, especially in places such as the United States, as the pathways to health impacts are complex and indirect. This study aims to conduct a comprehensive assessment of the effects of monthly drought exposure on respiratory mortality for NOAA climate regions in the United States from 2000 to 2018. A two-stage model …

Incorporating Resilience When Assessing Pandemic Risk In The Arctic: A Case Study Of Alaska, Sweta Tiwari, Andrey Petrov, Nino Mateshvili, Michele Devlin, Nikolay Golosov, Marya Rozanova-Smith, Mark Welford, John Degroote, Tatiana Degai, Stanislav Ksenofontov

Faculty Publications

The discourse on vulnerability to COVID-19 or any other pandemic is about the susceptibility to the effects of disease outbreaks. Over time, vulnerability has been assessed through various indices calculated using a confluence of societal factors. However, categorising Arctic communities, without considering their socioeconomic, cultural and demographic uniqueness, into the high and low continuum of vulnerability using universal indicators will undoubtedly result in the underestimation of the communities' capacity to withstand and recover from pandemic exposure. By recognising vulnerability and resilience as two separate but interrelated dimensions, this study reviews the Arctic communities' ability to cope with pandemic risks. In …

Non-Tuberculous Mycobacterium Correlation With Geochemical Characteristics Of Soil And Basalt In Hawaii, Leeza Marie Wells

Theses and Dissertations

Non-tuberculous mycobacteria (NTM) cause opportunistic lung disease though environmental exposure pathways. Among the United States, Hawaii has a significantly higher infection rate. Preliminary studies have shown certain environmental factors, such as phosphorus and other select soil geochemical characteristics, to be statistically significant to NTM occurrence. However, a model to predict NTM occurrence based on soil geochemistry had yet to be attempted. A selection of 40 NTM positive and 40 NTM negative soils from Oahu were selected for a geochemical analysis to search for possible correlations to mineralogy and elemental abundances that may promote, or inhibit, NTM growth in the environment. …

To Melt, Huanzhe Hu

Masters Theses

This thesis focuses on the need for a reevaluation of the relationship between humans and nature in the face of the current ecological crisis. The author argues that the dominant anthropocentric orientation, which sees nature as a resource to be exploited for human benefit, has led to over extraction and resource abuse, disrupting the balance of ecosystems. Instead, the author suggests adopting an ethical framework based on mutual understanding and appreciation, breaking the "hunter's gaze" and fostering empathy for non-human life forms. This thesis also explores the potential for new forms of communication and engagement with nature, such as through …

County Incidence And Geospatial Trends Of Early-Onset Hypertensive Disorders Of Pregnancy In Kentucky, 2008-2017, Courtney J. Walker, Anna Kucharska-Newton, Steven R. Browning, W. Jay Christian

UK CARES Faculty Publications

Background Early‑onset hypertensive disorders of pregnancy (eHDP) are associated with more severe maternal and infant outcomes than later‑onset disease. However, little has been done to evaluate population‑level trends. Therefore, in this paper, we seek to address this understudied area by describing the geospatial and temporal patterns of county‑level incidence of eHDP and assessing county‑level demographics that may be associated with an increased incidence of eHDP.

Methods Employing Kentucky certificates of live and stillbirth from 2008–2017, this ecological study detected county‑level clusters of early‑onset hypertensive disorders of pregnancy using SaTScan, calculated average annual percent change (AAPC) with a join point analysis, …

Beyond Covid-19: Designing Inclusive Public Health Surveillance By Including Wastewater Monitoring., Rochelle H. Holm, Na'taki Osborne Jelks, Rebecca Schneider, Ted Smith

Faculty and Staff Scholarship

Wastewater-based epidemiology is a promising and expanding public health surveillance method. The current wastewater testing trajectory to monitor primarily at community wastewater treatment plants was necessitated by immediate needs of the pandemic. Going forward, specific consideration should be given to monitoring vulnerable and underserved communities to ensure inclusion and rapid response to public health threats. This is particularly important when clinical testing data are insufficient to characterize community virus levels and spread in specific locations. Now is a timely call to action for equitably protecting health in the United States, which can be guided with intentional and inclusive wastewater monitoring.

Long-Term Mammal Herbivory On Arthropod Assemblages At Kruger National Park, South Africa, Ludzula Mukwevho, Tatenda Dalu, Frank Chidawanyika

All Peer-Reviewed Publications

Protected savannas are essential reserves for biological diversity, including endangered arthropod species, however, extreme grazing by mammals has cascading impacts on the communities and disrupts the functioning of these ecosystems globally. The current study assessed the abundance, species richness and composition of arthropods at the long-term grazing exclosures of Kruger National Park, South Africa. Pitfall traps and active searches were used to sample arthropods at the ungrazed, moderately, and heavily grazed exclosures. We found that Hymenoptera, Coleoptera, Diptera and Araneae were the most abundant orders of arthropods sampled. The abundance of multi-taxon, Diptera and Hymenoptera was significantly different between exclosures. …

Integrating Ocean Observations Across Body‐Size Classes To Deliver Benthic Invertebrate Abundance And Distribution Information, Henry A. Ruhl, Brian J. Bett, Jeroen Ingels, Adrian Martin, Andrew R. Gates, Andrew Yool, Noëlie M.A. Benoist, Ward Appeltans, Kerry L. Howell, Roberto Danovaro

School of Biological and Marine Sciences

Invertebrate animals living at the seafloor make up a prominent component of life globally, spanning 10 orders of magnitude in body size over 71% of Earth's surface. However, integrating information across sizes and sampling methodologies has limited our understanding of the influence of natural variation, climate change and human activity. Here, we outline maturing practices that can underpin both the feasibility and impact of establishing Benthic Invertebrate Abundance and Distribution as a Global Ocean Observing System—Essential Ocean Variable, including: (1) quantifying individual body size, (2) identifying the well‐quantified portions of sampled body‐size spectra, (3) taking advantage of (semi‐)automated information processing, …

Sustainability Analysis: Large-Scale Desalination Implications For Coastal California, Elizabeth H. Whitford

Master's Projects and Capstones

In response to prolonged drought, desalination is gaining popularity as an alternative water production method for fresh water. However, water desalting technology poses concerns; the process is energy intensive, creates brine waste, and has the potential to damage sensitive coastal ecosystems. Significant research is available on the technological, economic, and energy efficiency aspects of desalination, while only a small percentage of the current literature focuses on environmental impacts. This research analyzes the desalination literature holistically in terms of both energy consumption and environmental impacts by conducting 1) a historical and current state review of the sector, 2) a technology analysis …

The Role Of Coping Motives In The Relationship Between Ptsd And Alcohol-Related Consequences In Oef/Oif Veterans, Cameron Quan

Electronic Theses and Dissertations Archive

Post-Traumatic Stress Disorder (PTSD) and Alcohol Use Disorder (AUD) are highly comorbid, and this co-occurrence is of particular concern among veterans. Alcohol misuse has shown to be a method of coping with negative PTSD symptoms. In a harm reduction approach, alcohol-related consequences can serve as an outcome measure in the testing of brief alcohol interventions when measured through severity level. The current investigation is a secondary analysis using data from a trial of two brief interventions used in a veteran sample published by McDevitt-Murphy and colleagues (2014). This study investigated: (a) the 3-factor model of the DrInC and (b) the …

Evaluating The Ability Of Constructed Intertidal Eastern Oyster (Crassostrea Virginica) Reefs To Address Shoreline Erosion In South Carolina, Peter R. Kingsley-Smith, Andrew W. Tweel, Sharleen P. Johnson, Gary W. Sundin, Michael S. Hodges, Benjamin W. Stone, Gregory D. Sorg, Denise M. Sanger

Journal of South Carolina Water Resources

The application of nature-based solutions to address shoreline erosion and the loss of salt marsh in coastal South Carolina has centered around the creation of intertidal oyster (Crassostrea virginica) reefs that act as natural breakwaters. The installation of such living shoreline materials often results in a rapid accumulation of fine sediments, followed by wild oyster recruitment to suitable materials, and then more gradually the growth of salt marshes (primarily Spartina alterniflora). Leveraging more than two decades of oyster reef restoration and living shorelines research at the South Carolina Department of Natural Resources, this study quantitatively assessed performance rates for both …
