The School Neighborhood Environment For Childhood Obesity In A Rural Texas Community, Jin Young Choi, David Pate

Journal of Rural Social Sciences

This paper examines the school neighborhood environments related to childhood obesity in a rural community in Texas, focusing on the assessment of three aspects: socioeconomic characteristics, food environment, and physical activity environment. Different methodological approaches were employed to characterize the aspects of the school neighborhood environments. Most public schools in the community were located in low-income neighborhoods. There were disproportionately high concentrations of fast food restaurants and convenience stores within the active travel-to-school zone. Most of the students who lived in the active travel-to-school zone did not walk or bike to school, and student safety was identified as the predominant …

Ecopsychology And Race : An Exploratory Study, Luke B. Woodward

Theses, Dissertations, and Projects

While ecopsychology has brought critical attention to the relationship between the natural environment and the human psyche, very little has been written about how race and racism shape our experience of the natural world. This qualitative study asked the following central question: How are race and racism relevant to ecopsychology in theory and practice? Twelve semistructured interviews were conducted with a racially diverse group of ecopsychologists, environmental justice activists and spiritual leaders. Interview data emphasized the importance of employing a broad definition of ecopsychology that encompasses not only the relationship between psyche and nature, but the relationship between psyche, nature …

High Muscle Mitochondrial Volume And Aerobic Capacity In A Small Marsupial (Sminthopsis Crassicaudata) Reveals Flexible Links Between Energy-Use Levels In Mammals, Terence Dawson, Koa Webster, Enhua Lee, William A. Buttemer

Faculty of Science, Medicine and Health - Papers: part A

We investigated the muscle structure–function relationships that underlie the aerobic capacity of an insectivorous, small (~15 g) marsupial, Sminthopsis crassicaudata (Family: Dasyuridae), to obtain further insight into energy use patterns in marsupials relative to those in placentals, their sister clade within the Theria (advanced mammals). Disparate hopping marsupials (Suborder Macropodiformes), a kangaroo (Macropus rufus) and a rat-kangaroo (Bettongia penicillata), show aerobic capabilities as high as those of ‘athletic’ placentals. Equivalent muscle mitochondrial volumes and cardiovascular features support these capabilities. We examined S. crassicaudata to determine whether highly developed aerobic capabilities occur elsewhere in marsupials, rather than being restricted to the …

Perceived Neighborhood Safety And Psychological Distress: Exploring Protective Factors, Jaime Booth, Stephanie L. Ayers, Flavio F. Marsiglia

The Journal of Sociology & Social Welfare

While a growing body of literature has established a relationship between "disordered" neighborhoods and psychological distress, less is known about the specific mechanisms at work. Using data collected in the 2008 Arizona Health Survey (N = 4,196), hierarchal linear regression was conducted to assess both the independent effect of perception of neighborhood safety on psychological distress, as well as the mediating effects of powerlessness, social isolation and mistrust. The findings suggest that the more safe individuals feel in their neighborhood, the less psychological distress they experience (b = 1.07, SE = .17, p < .001). This relationship appears to be partially mediated by feelings of powerlessness, social isolation and mistrust, indicating potential risk and protective factors.

Habitat Modeling Of Three Endemic Crayfish Species In The Black River Drainage Of Missouri And Arkansas: Factors Affecting Distribution And Abundance, Matthew Stephen Nolen

Graduate Theses and Dissertations

The Ozark faunal region of Missouri and Arkansas harbors a high level of aquatic biological diversity, especially in regards to endemic crayfish. Orconectes eupunctus, Orconectes marchandi, and Cambarus hubbsi are three such endemics that are threatened by a limited natural distribution and the invasions of Orconectes neglectus. I sought to determine how natural and anthropogenic factors influence these three species across multiple spatial scales. Local and landscape data were used in decision tree analyses (CART) to determine their influence effect on presence/absence and density of the three species. Predictive models were validated using k-fold cross validation. O. eupunctus presence was …

Assessing The Impacts Of Dams On Nutrient And Sediment Loading In The Kalamazoo River Using The Soil And Water Assessment Tool (Swat), Daniel Henry Serfas

Masters Theses

The Soil and Water Assessment Tool (SWAT) was applied to the Kalamazoo River Watershed in order to evaluate the impacts that several dams within a superfund site "Area of Concern" have on the sediment, nutrients, and streamflow of the system. It was hypothesized that the SWAT model could be used to recreate the watershed in hopes of estimating the amounts of nitrogen, phosphorus, and sediment that would result from the removal of the dams. The model would then be used to evaluate dam removal scenarios to come up with a best management practice (BMP).

The model was calibrated, however, during …

Graph Matching Based Decision Support Tools For Mitigating Spread Of Infectious Diseases Like H1n1, Jomon Aliyas Paul, Kedar Sambhoos

Faculty Articles

Diseases like H1N1 can be prevented from becoming a wide spread epidemic through timely detection and containment measures. Similarity of H1N1 symptoms to any common flu and its alarming rate of spread through animals and humans complicate the deployment of such strategies. We use dynamic implementation of graph matching methods to overcome these challenges. Specifically, we formulate a mixed integer programming model (MIP) that analyzes patient symptom data available at hospitals to generate patient graph match scores. Successful matches are then used to update counters that generate alerts to the Public Health Department when the counters surpass the threshold values. …

Science And Technology Resources On The Internet: Biodiversity Web Resources, John Creech

Library Scholarship

Biodiversity, a contraction of the phrase "biological diversity," was first used by Walter G. Rosen during a planning meeting for the 1986 National Forum on BioDiversity held in Washington, DC, while the first appearance of the word in the print literature likely occurred with the 1988 publication of the proceedings of this conference (Hawksworth 1995). The term "biodiversity" first appeared in the Biodiversity Web Resources http://www.istl.org/12-fall/internet.html 1 of 15 3/11/14 11:26 AM BIOSIS database in 1988 with four references, but by April of 1994 the count of citations had increased to 888 (Hawksworth 1995).

Over the last decade scientists have …

Gatekeeper Training As A Preventative Intervention For Suicide: A Systematic Review, Michael Isaac, Brenda Elias, Laurence Y. Katz, Shay-Lee Belik, Frank P. Deane, Murray W. Enns, Jitender Sareen

Frank Deane

Gatekeeper training is successful at imparting knowledge, building skills, and molding the attitudes of trainees; however, more work needs to be done on longevity of these traits and referral patterns of gatekeepers. There is a need for randomized controlled trials. In addition, the unique effect of gatekeeper training on suicide rates needs to be fully elucidated.

Essays On Spatial Analysis Of Policy Impacts, Daegoon Lee

Masters Theses

This thesis is composed of two essays under the theme of spatial analysis of policy impacts. The objective of the first essay was to analyse how population dynamics affect greenhouse gas (GHG) emissions. The effects of population redistribution resulting from the South Korean government’s decentralization efforts on GHG emissions were assessed. Simulation results suggest that the direction of change in total GHG emissions depends on the share of the population redistributed from higher to lower population density regions. If the entire redistributed population of 877,000 persons expected from the government’s decentralization project were from the Seoul Area, annual CO_{2 …}

New Paleoclimate Reconstruction Techniques In Archaeology: Applications In Greece, New Mexico, And Portugal, Brandon Lee Drake

Anthropology ETDs

This dissertation develops new techniques of analysis that make existing archaeological data more useful for understanding past climate change. These techniques are introduced through three key case studies in the San Juan Basin of New Mexico, the Lower Alentejo of Portugal, and the Eastern Mediterranean. A 12,000 year record of pollen collected from packrat middens across Chaco Canyon were analyzed using a new normalization procedure to produce a Holocene record of piñon and ponderosa pine abundance. The normalization procedure, species occurrence, enabled statistical analysis of the data. Simple linear models indicated that piñon and ponderosa pollen were strongly correlated with …

Cumulative Risk And A Call For Action In Environmental Justice Communities, H. P. Hynes, Russ Lopez

Journal of Health Disparities Research and Practice

Health disparities, social inequalities, and environmental injustice cumulatively affect individual and community vulnerability and overall health; yet health researchers, social scientists and environmental scientists generally study them separately. Cumulative risk assessment in poor, racially segregated, economically isolated and medically underserved communities needs to account for their multiple layers of vulnerability, including greater susceptibility, greater exposure, less preparedness to cope, and less ability to recover in the face of exposure. Recommendations for evidence-based action in environmental justice communities include: reducing pollution in communities of highest burden; building on community resources; redressing inequality when doing community-based research; and creating a screening framework …

Religion And Infant Mortality In The United States: A Community-Level Investigation Of Denominational Variations, Ginny Garcia-Alexander, John P. Bartkowski, Xiaohe Xu

Sociology Faculty Publications and Presentations

A burgeoning body of scholarship has explored the influence of community-level religiosity (religious ecology) on various health outcomes. In this study, we enlist data from the Glenmary Census of Churches, county-level infant mortality rates from the NCHS, and select Census data to investigate the relationship between infant mortality and religion. Our study employs both aggregate analyses of major faith traditions (conservative Protestant, mainline Protestant, Catholic, and other religions) as well as decomposition analyses that subdivide conservative Protestants into four variants: fundamentalist, evangelical, Pentecostal, and other conservative Protestant. Our preliminary findings suggest that counties with a high prevalence of Catholic and …

Niche Theory In New Media: Is Digital Overtaking The Print Magazine Industry?, Zeenath Haniff

UNLV Theses, Dissertations, Professional Papers, and Capstones

New challengers in mass media are poised to annihilate the competition. The trials and tribulations that magazine publishers have conquered over the years is a testament to the industry's undaunted resilience and perseverance against such competition. Presently, the paper-based medium has enjoyed massive success by catering to readers' individual interests in special interest publications called niche magazines. However, the future of print magazines is unclear as recent technological innovations in digital publishing become the latest contender against print media. Analyzing the possible effects of the new digital medium upon the incumbent print magazine may help publishers prepare to face their …

Reconstruction Of Fire History In The National Key Deer Refuge, Monroe County, Florida, U.S.A.: The Palmetto Pond Macroscopic Charcoal Record, Desiree Lynn Kocis

Masters Theses

The pine rocklands in the Lower Florida Keys are considered endangered because of rises in sea level, urbanization, and human impacts on the natural fire regime. Macroscopic charcoal in a sediment core recovered from Palmetto Pond (24°41’45.15”N, 81°19’43.84”W) in 2010 was examined in contiguous 1-cm intervals to reconstruct Late Holocene fire history. Palmetto Pond is a shallow freshwater solution hole located within the pine rocklands of No Name Key in Monroe County, Florida. Radiocarbon dating of plant material at 247 cm depth in the Palmetto Pond profile indicates the sediment record extends back to ca. 4500 cal yr BP. Charcoal …

Information and communication technologies for citizen science can enable massive virtual collaborations based on voluntary contributions by diverse participants. As the popularity of citizen science increases, scientists need a more thorough understanding of how project design and implementation decisions affect scientific outcomes.

Applying a comparative case study methodology, the study investigated project organizers' perspectives and experiences in Mountain Watch, the Great Sunflower Project, and eBird, three observation-based ecological citizen science projects in different scientific domains. Five themes are highlighted in the findings: the influence of project design approaches that …

A Multi-Phase, Mixed-Method Regional Analysis Of Lake And Reservoir Based Recreational Opportunities In Utah, William S. Spain

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Managing and planning for human use at lakes and reservoirs creates challenges for land and water management agencies in Utah and the country as a whole. In spite of increased attention and research, management problems such as conflicts, accidents, and site impacts continue to occur. These problems have been exasperated by an 800% increase in the number of registered boats statewide over the past 50 years. As such, developing new strategies to address the broad array of management challenges could be beneficial to the recreation management of lakes and reservoirs. This study, conducted in collaboration with Utah State Parks, considers …

An Alternate Approach To Ecosystem Mapping: Fusing Orthophotography With Landsat Etm+ Data For A Object-Based Classification, South Eastern Arkansas., David Mcfee

Graduate Theses and Dissertations

Maintaining representative sampling of biologically rich and rare ecosystems has become an important means to preventing biodiversity loss. A limitation in indentifying and quantifying ecosystems is the cost of obtaining high resolution imagery necessary for a high resolution land cover assessment. This research shows how free, different resolution imagery (orthoimages and LANDSAT ETM+) could be combined to produce a hybrid dataset with enhanced spectral, spectral and temporal properties, and processed to obtain a object-based classification of land cover of bottomland and pine hardwood forest in south eastern Arkansas. Three classification techniques were evaluated: 1) a human derived, rule based method, …

Understanding Resistance To Standardization In Education: The Tragedy Of The Commons As A Theoretical Framework, Grinell Smith, Colette Rabin

Faculty Publications

The purpose of this paper is to articulate how a theory, developed in 1968 by Garrett Hardin to describe how shared resources, or “commons” can become depleted, also elucidates the mechanism by which standardization of educational outcomes and assessment have come to dominate current education discourse. We then present results of a case study of a school struggling to succeed within a context of a district’s hyper-focus on standardized measures of success, and employ the theory to illustrate its usefulness to explain what we found at the school site. We believe this theoretical framework provides interesting perspectives on current trends …

All Roads Lead To Fragmentation: Exploring Habitat Connectivity And Wildlife Underpasses Through The Florida Panther And The Jaguar, Carroll Courtenay

Geography and the Environment Capstone Projects

The global transportation system is the “giant now embracing us,” and its omnipresent nature influences ecosystems worldwide (Forman, 1998: iv). The diversity of environmental effects associated with transportation systems challenges researchers to focus on concrete aspects of intertwined ecological systems. Examining habitat fragmentation associated with transportation networks, however, exposes some of the most direct impacts of these networks on fauna populations. As transportation networks expand, road corridors hinder habitat connectivity, which can greatly impact habitat health and genetic diversity in ecosystems (Corlatti et al., 2009; Tewksbury et al., 2002). Animal-vehicle collisions, decreased reproductive success, movement constraints, decreased colonization, and increased …

Existing Knowledge, Understudied Ecosystems, And Rapid Development: The Environmental Impacts Of Roads On The Wetlands Of The Pantanal, South America, Ethan Strickler

Geography and the Environment Capstone Projects

Wetlands are particularly diverse habitats because they are home to both aquatic and terrestrial flora and fauna. Wetlands are important for conservation because they are often home to many rare and endangered species. For example, in the United States alone, over a third or all rare or endangered species reside in wetlands. Wetlands offer many benefits for both humans and wildlife because they are hydrologic modifiers, wildlife centers, and beneficial for both water quality and nutrient cycling (Forman, et al. 2003). As wildlife centers, wetlands are the most botanically productive habitats on earth and support high abundance and diversity of …

Parochlus Kiefferi (Garrett, 1925) In Nebraska (Diptera: Chironomidae), Barbara Hayford

Great Plains Research: A Journal of Natural and Social Sciences

A rare species of nonbiting aquatic midge, Parochlus kiefferi (Garrett, 1925), was discovered in Squaw Creek in the Pine Ridge of northwest Nebraska. Parochlus is a genus of midge found throughout the Southern Hemisphere and is only represented by this one species in the Northern Hemisphere. The typical North American species distribution of P. kiefferi includes high alpine and northern latitude streams, so the collection of P. kiefferi from a low elevation and low-latitude stream in Nebraska represents a range extension for the species. A survey for P. kiefferi from 83 samples from 53 stream sites in northern Nebraska yielded …

The Vacb Model In Hòa An Village And Xeo Trâm Hamlet: Comparison And Analysis Through A Gendered Lens, Alyssa Bosold

Independent Study Project (ISP) Collection

Burning fuel-wood, a method of traditional cooking practiced by half of all homes in Vietnam (Global Alliance for Clean Cook-stoves 2012) and the majority of homes in Hòa An Village and Xeo Trâm Hamlet, has significant negative consequences in terms of environmental and personal health. In Hòa An Village and Xeo Trâm Hamlet, as is true in much of Vietnam, gender roles dictate that women should be primarily responsible for household chores like cooking (World Bank 2001, Nguyen 2012, Nguyen 2012, Vo 2012). This means that women must often deal directly with the environmental dangers and safety hazards of woodstoves. …

Firearms, Youth Homicide, And Public Health, Robert S. Levine, Irwin Goldzweig, Barbara Kilbourne, Paul Juarez

Sociology Faculty Research

Homicide is seven times as common among U.S. non-Hispanic Black as among non-Hispanic White youth ages 15 to 24 years. In 83% of these youth homicides, the murder weapon is a firearm. Yet, for more than a decade, the national public health position on youth violence has been largely silent about the role of firearms, and tools used by public health professionals to reduce harm from other potential hazards have been unusable where guns are concerned. This deprives already underserved populations from the full benefits public health agencies might be able to deliver. In part, political prohibitions against research about …
