Garland, Prue H. Hart, David G. Hoel, Ramune Jacobsen, Pelle G. Lindqvist, David J. Llewellyn, Henning Tiemeier, Richard B. Weller, Antony R. Young

Chemistry Faculty Publications

This article aims to alert the medical community and public health authorities to accumulating evidence on health benefits from sun exposure, which suggests that insufficient sun exposure is a significant public health problem. Studies in the past decade indicate that insufficient sun exposure may be responsible for 340,000 deaths in the United States and 480,000 deaths in Europe per year, and an increased incidence of breast cancer, colorectal cancer, hypertension, cardiovascular disease, metabolic syndrome, multiple sclerosis, Alzheimer's disease, autism, asthma, type 1 diabetes and myopia. Vitamin D has long been considered the principal mediator of beneficial effects of sun exposure. …

Using Soil Geospatial Properties And Environments To Explore Microbial Diversity, Sharon Faye Smith

Graduate Theses and Dissertations

Soil microorganisms help maintain nutrient cycling, control carbon sequestration, impact plant productivity, and influence several soil chemical and physical properties; yet, the processes that control the microbial composition of soil and how environmental changes may affect the composition and activity of these organisms at different scales remains a difficult and intriguing puzzle for soil scientists, ecologists, and modelers. Wetlands are endangered and important ecosystems that provide several services, which are directly linked to soil function. However, few wetland assessments consider the soil environment and microbial ecology. Linking soil microbial community composition and distribution patterns to soil physio-chemical properties would provide …

The Role Of Strategic Governance In Reducing Infant Mortality Under Crisis Conditions, Lynn Christine Finley

Dissertations and Theses

The infant mortality rate (IMR) in some developing countries has decreased faster than the global average even though these countries lack strong economic growth, good governance, and democracy (often acknowledged precursors to improved health outcomes). What accounts for the improvement of the IMR in the absence of these traditional pathways to health gains? Some scholars suggest that the concept of "strategic governance" might help direct attention to intermediary factors that reduce neonatal deaths in countries that experience crisis conditions. The main objective of this dissertation is to investigate the set of governance practices that have reduced IMR in two such …

Dyslexia Beyond The Word: An Ecological Study Of Specific Reading Disorder, Benjamin T. Carter

Theses and Dissertations

This dissertation discusses the effects of dyslexia on reading behavior and cognition. It does so by first outlining the overall incidence of dyslexia, providing current definitions, giving a history of scientific inquiry and discussing relevant contemporary research. Thirteen different analyses are then discussed (ten a priori and three post-hoc). Individuals with dyslexia were found to have increased fixation duration, first run dwell time, total dwell time, and refixation probability. The dyslexia group was also highly sensitive to lexical predictability. Within the reading network, the BOLD response was depressed in dyslexia during reading in the following regions: the left medial and …

Community Music Therapy For Marginalized Middle School Students, Karen J Mathews

Expressive Therapies Capstone Theses

Abstract

Community Music Therapy has been a recent development in the field of Music Therapy. Community Music Therapy occurs at the intersection of traditional Music Therapy and Community Music.

This paper explores a project using Community Music Therapy with a group of self-selected middle school students in addressing concerns and emotions around equity, diversity, and inclusion. The results of this project demonstrated that Community Music Therapy is an …

Variability Among Later Stone Age Hunter-Gatherers, Mica Jones

Arts & Sciences Graduate Student Theses and Dissertations

The hunting and gathering way of life is the most enduring and resilient in human history. However, the ways that a wild food-based subsistence system affects people’s social and economic organization are often oversimplified and variability is poorly understood. In general, there’s been a tendency, particularly among non-Anthropologists, to assume that hunter-gatherer societies are static and that historic groups represent an earlier, simpler way of life. This is particularly true in Africa, where small, highly mobile groups are common ethnographically. However, dramatic rainfall fluctuations over the last ~30,000 years significantly altered resources available to hunter-gatherers in diverse environments of northern …

Dissertations and Theses (Open Access)

Unconventional gas and oil drilling (UGOD) has increased substantially in the United States for more than a decade. The resultant environmental unsafe air pollution effects of UGOD both locally and regionally have been well documented in the literature. Despite the dramatic increase in unconventional well drilling and the toxicant exposure, the health consequences of UGOD remain largely uncertain. This study assesses the relationship between active wells and healthcare use for respiratory diseases by zip code from 2004 to 2008 in the Barnett shale area of Texas. The first modern shale gas well was drilled in the Barnett shale area of …

Characterizing The Impacts Of The Invasive Hemlock Woolly Adelgid On The Forest Structure Of New England, Peter Brehm Boucher

Graduate Doctoral Dissertations

Climate change is raising winter temperatures in the Northeastern United States, both expanding the range of an invasive pest, the hemlock woolly adelgid (HWA; Adelges tsugae), and threatening the survival of its host species, eastern hemlock (Tsuga canadensis). As a foundation species, hemlock trees underlie a distinct network of ecological, biogeochemical, and structural systems that will likely disappear as the HWA infestation spreads northward. Remote sensing can offer new perspectives on this regional transition, recording the progressive loss of an ecological foundation species and the transition of evergreen hemlock forest to mixed deciduous forest over the course of the infestation. …

Road Development In Asia: Assessing The Range-Wide Risks To Tigers, Neil Carter, Alexander Killion, Tara Easter, Jodi Brandt, Adam Ford

Human-Environment Systems Research Center Faculty Publications and Presentations

Roads are proliferating worldwide at an unprecedented rate, with potentially severe impacts on wildlife. We calculated the extent and potential impacts of road networks across the 1,160,000-km², 13-country range of the globally endangered tiger (Panthera tigris)—a conservation umbrella species. We found that roads were pervasive, totaling 134,000 km across tiger conservation landscapes (TCLs), even in tiger priority sites and protected areas. Approximately 43% of the area where tiger breeding occurs and 57% of the area in TCLs fell within the road-effect zone. Consequently, current road networks may be decreasing tiger and prey abundances by more than …

Ecological And Economic Benefits And Risks Of Using Botanical Insecticides In Tanzanian Farms, Lilia Garcia

Independent Study Project (ISP) Collection

Insect damage is a major concern for smallholder farmers in developing countries like Tanzania. Synthetic insecticides can tame infestations, however they can be expensive, inaccessible, and their misuse can threaten farmer health and ecological conditions. Botanical insecticides are cheap alternatives to treat infestations while preserving beneficial insects such as pollinators, predators, and parasitoids. This study assesses how both synthetic and botanical insecticides affect beneficial insects, crop yield and profit/costs. This study finds botanical insecticides slightly less harmful towards non-target insects. Botanical insecticides seldomly improve crop yields but usually result in a higher profit/lower cost. Due to high variation in ecological …

A Global Regression Method For Thermal Sharpening Of Urban Land Surface Temperatures From Modis And Landsat, James. W. Wang, Winston T. L. Chow, Yi-Chen Wang

Research Collection School of Social Sciences

Land surface temperatures (LST) in urban landscapes are typically more heterogeneous than can be monitored by the spatial resolution of satellite-based thermal infrared sensors. Thermal sharpening (TS) methods permit the disaggregation of LST based on finer-grained multispectral information, but there is continued debate over which spectral indices are most appropriate for urban TS, and how they should be configured in a predictive regression framework. In this study, we evaluate the stability of various TS kernels with respect to LST at different spatial (Landsat 8) and diurnal (MODIS) scales, and present a new TS method, global regression for urban thermal sharpening …

"It Does N'T Seem Like A Big Deal": A Media Ecology Analysis Of Digital Teen Sexuality And Sexting Education, Allison Marie Metz

Theses and Dissertations

In the state of Illinois, any person in possession of sexually explicit photos of a minor, even if the subject is oneself, can be prosecuted as a felon for possession of child pornography and be required to registered as a sex-offender (705 ILCS § 405). Concurrently, the recent trend of ‘send nudes’ depicts humorous ways to request the transmission of sexually explicit photos, increasing this act as a normative practice for young people (Bradford, 2018; Thomas, 2017). This trend is incongruent with Illinois statue (705 ILCS § 405) and school administrative policy about transmitting sexually explicit photos of a minor. …

Minority Stress Among Gay And Bisexual Men In Agricultural Occupations, Michael C. Parent, Garrett M. Steede

Journal of Rural Social Sciences

Research integrating the minority stress model and vocational behavior has used broad samples of sexual minority persons. Specific work contexts, particularly traditionally masculine work contexts, may be relevant areas to the integration of minority stress theory and vocational well-being. This study examined the relationship between workplace heterosexism and job satisfaction, as moderated by identity management and person-organization fit, among a sample of 114 sexual minority men, employed in agriculture, recruited from an online social network group. Contrary to prior research, integrating identity management did not moderate the relationship between workplace heterosexism and job satisfaction. Person-organization fit did moderate this relationship, …

Elemental Climate Disaster Texts And Queer Ecological Temporality, Laura Mattson

USF Tampa Graduate Theses and Dissertations

This thesis approaches climate disaster texts as an opportunity to challenge constructions of the body, space, and time. Developed from embodied experiential knowledge about hurricanes, my work will explore how climate disasters can teach us to reimagine human-nature relationships. In my two analysis chapters, I use critical textual analysis and autoethnography to challenge particular representations of the human-nature relationship as a binary between nature and culture. By intervening in the nature-culture binary, I theorize queer ecological temporality as an opportunity to reveal and challenge constructions of nature and time. Working at the intersections of queer and ecocritical theory, this thesis …

Cats And Conservationists: The Debate Over Who Owns The Outdoors, Dara M. Wald, Anna L. Peterson

Purdue University Press Book Previews

Cats and Conservationists is the first multidisciplinary analysis of the heated debate about free-roaming cats. The debate pits conservationists against cat lovers, who disagree both on the ecological damage caused by the cats and the best way to manage them. An impassioned and spirited conflict, it also sheds light on larger questions about how we interpret science, incorporate diverse perspectives, and balance competing values in order to encourage constructive dialogue on contentious social and environmental issues.

On one side of the cat debate stand many environmentalists, especially birders and conservation organizations, who believe that outdoor cats seriously threaten native wildlife. …

Assessing Boreal Peat Fire Severity And Vulnerability Of Peatlands To Early Season Wildland Fire, Laura Bourgeau-Chavez, Sarah L. Grelik, Michael Billmire, Liza K. Jenkins, Eric S. Kasischke, Merritt R. Turetsky

Michigan Tech Publications, Part 1

Globally peatlands store large amounts of carbon belowground with 80% distributed in boreal regions of the northern hemisphere. Climate warming and drying of the boreal region has been documented as affecting fire regimes, with increased fire frequency, severity and extent. While much research is dedicated to assessing changes in boreal uplands, few research efforts are focused on the vulnerability of boreal peatlands to wildfire. In this case study, an integration of field data collection, land cover mapping of peatland types and Landsat-based fire severity mapping was conducted for four early season (May to mid-June) wildfires where peatlands are abundant in …

Cancer Health Disparities Among African Americans: A Socioecological Approach, Seth M. Spitzley

The Hilltop Review

Research shows that health outcomes are influenced by race or ethnicity, socioeconomic status, education and literacy levels, and the physical environment (U.S. Department of Health and Human Services, 2014). The health statuses of minority groups, such as African Americans, are adversely impacted by inequality (Randall, 2009). In Kalamazoo, Michigan, the leading cause of death for all residents in Kalamazoo County was cancer, where black individuals have the highest death rate among any other racial or ethnic group. That African Americans comprise less than 11% of the population in Kalamazoo County thus suggests that African Americans are disproportionately impacted by cancer …

Economic Impacts Of Coastal Hazards On Mississippi Commercial Oyster Fishery From 2005 To 2016, Benedict C. Posadas

Journal of Ocean and Coastal Economics

This paper attempted to quantify the commercial fishery impacts consisting of wild harvest losses of oysters by commercial Mississippi fishers due to coastal hazards since 2005. The economic impacts of coastal hazards on the Mississippi oyster fishery included the direct losses associated with Katrina in 2005, the oil spill in 2010, spillway opening in 2011 and harmful algal blooms in 2015. The cumulative economic direct impacts on the Mississippi oyster reached almost $40 million, averaging about $3.3 million per year. Long-term data were compiled to develop economic recovery models for the Mississippi oyster fishery. The economic recovery model attempted to …

Authentic Perspectives On Autistic Resilience: Implications For Schools And Society, Andrew Nelson

Theses, Dissertations and Capstones

This study explored resilience factors as identified by autistic adults with authentic lived experience. Historically, Autism Spectrum Disorder (ASD) has been diagnosed using deficit models and criteria designed by outsiders with little input from the autism community. While risk of adversity is often high for those with ASD, scant research exists looking at the strengths, adaptive skills, and environmental factors contributing to the resilience of people with ASD. Autistic adults were interviewed (N = 10) to assess which internal and external risks and protections participants deemed important to their resilience. Responses were coded, analyzed, and compared to existing resilience data …

Is The World Converging To A ‘Western Diet’?, Azzeddine Azzam

Department of Agricultural Economics: Faculty Publications

Objective: To test the nutrition transition hypothesis of global dietary convergence to a ‘Western diet’.

Design: Consumer-waste-adjusted FAO Food Balance Sheets are used to construct for each country a Western Diet Similarity Index (WSI), expressed as a ratio of calories from animal-sourced foods, oils, fats and sweeteners to total per capita calories. β-Convergence and associated speed are estimated by growth regressions using 1992–2013 panel data. Speed of convergence, a non-linear function of income per capita, globalisation and urbanisation, determines the steady-state or long-term global WSI. The long-term global WSI is compared with the WSI of the group of countries with …

Beyond Never-Never Land: Integrating Lidar And Geophysical Surveys At The Johnston Site, Pinson Mounds State Archaeological Park, Tennessee, Usa, Henry R. Edward, Alice P. Wright, Sarah C. Sherwood, Barrier R. Casey, Stephen B. Carmody, Christopher Van De Ven

Anthropology Faculty Research and Scholarship

Archaeologists often use near-surface geophysics or LiDAR-derived topographic imagery in their research. However, rarely are the two integrated in a way that offers a robust understanding of the complex historical palimpsests embedded within a social landscape. In this paper we present an integrated aerial and terrestrial remote sensing program at the Johnston Site, part of the larger Pinson Mounds landscape in the American MidSouth. Our work at Johnston was focused on better understanding the history of human landscape use and change so that we can begin to compare the Johnston Site with other large Middle Woodland (200 BC-AD 500) ceremonial …

Geospatial Analysis Of Flooding In The Cypress Creek Watershed Due To Urban Sprawl, Michael Roland Boucher

Walden Dissertations and Doctoral Studies

Harris County, Texas, experiences flooding almost every year, and the situation is getting worse. Uncontrolled development is leading to an increase in flooding events. This study investigated how rapid urbanization and sprawl led to a higher frequency and intensity of flooding in the Cypress Creek watershed in northern Harris County. According to urban ecology, the basis of the theoretical framework, the human actions on the environment are not just bystanders, but direct contributors as inputs. In this case, the outputs are the intensity of the flooding events caused by Hurricane Ike, the Memorial Day flood of 2016, and Hurricane Harvey. …

Diet Of A Recently Reintroduced River Otter (Lontra Canadensis) Population In Taos County, New Mexico, Gabriela Alexandra Wolf-Gonzalez

Theses and Dissertations--Forestry and Natural Resources

North American river otters (Lontra canadensis), native to every U.S. state and Canada, experienced extensive population decreases and range reduction until the mid-20th century as a result of overexploitation and habitat loss during European colonization. The last known river otter in New Mexico was killed on the Gila River in 1953, although unverified reports continued thru 2008. After a nearly 60-year absence from New Mexico, 33 adult river otters were reintroduced to the Rio Pueblo de Taos in the northern part of the state between 2008-2010; however, they were not subsequently monitored or studied. I characterized diet of …

Assessing The Climate Water Balance Model’S Ability To Predict Soil Moisture Variability And Species Distribution Of A Forested Watershed In The Northern Cumberland Plateau, Katherine J. Love

Theses and Dissertations--Forestry and Natural Resources

Spatial patterns of moisture and tree species have been studied using environmental gradients, often represented by terrain attributes in GIS. With climate change, GIS terrain variables, which are static as long as the elevation remains unchanged, will not reflect alterations in temperature, water cycle, and atmospheric conditions. In this thesis, the commonly used terrain variables and climate water balance variables were evaluated and compared for their ability to explain soil moisture and tree species distributions in a forested watershed in the Northern Cumberland Plateau. The results suggest that GIS terrain variables generally perform better than climate water balance variables, however, …
