A modified nominal group technique was used that involved 67 participants in ten nominal groups and identified the most important ideas about how OSH professionals can influence workplace safety and health decision making. The research produced themes of communication, scientific, professionalism, leadership, adaptability, and business acumen that resulted in six domains of occupational safety and health professional influence.

Burning Community Integration And Disability, Christopher Shane Brace

Graduate Theses and Dissertations

Individuals with anxiety and depression have always been marginalized and stigmatized. Individuals with “hidden” disabilities are encouraged by society to keep them hidden, or face ridicule and persecution. Society decreases their sense of self-worth, and self-efficacy by destroying any perception of normalcy. Social support resources are vital for individuals with anxiety and depression’s continued mental health. As time goes on the individuals experience a decrease in the amount of available resources, at the same time the need for them increases. These individuals need a way to quickly replenish their social resources and the Burning Man regional network creates a unique …

Decadal Land Surface Phenology And Water Quality In The Headwaters Illinois River Watershed, Justin Ray Rollans

Graduate Theses and Dissertations

Over 25 percent of the world’s population either lives on or obtains water from karst aquifers. The complex interactions between subsurface karst geologic features, the constant motion of the plant life cycle, and significant water resource demand all suggest the need to better define those interactions. The relationship of historical land surface phenology and water quality in karst topography were investigated in the Headwaters Illinois River watershed in Northwest Arkansas (NWA). This area represents high vulnerability to surface water and groundwater contamination, with both natural and anthropogenic processes such as over application of broil litter for enhanced cattle browse, affecting …

Systems To Attract And Feed Pollinators In Warm-Season Lawns, Michelle Wisdom

Graduate Theses and Dissertations

Pollinating insects are responsible for the production of many agricultural crops and they require floral resources to fulfill their life-cycle. Ideally, pollinating insects will encounter a diversity of floral resources across their entire season of activity, and those floral resources can include both herbaceous and woody plant species. Managed turfgrass areas have been identified as potential locations for creating pollinator-friendly habitats. In the transition zone, where both warm- and cool-season turfgrass species are present, the persistence of herbaceous plants in warm-season turfgrasses such as bermudagrass (Cynodon spp.) and buffalograss (Buchloe dactyloides), may be affected not only by the competitive nature …

Spatio-Temporal Reconstruction Of Remote Sensing Observations, Kamrul Khan

Graduate Theses and Dissertations

The USDA Forest Service aims to use satellite imagery for monitoring and predicting changes in forest conditions over time within the country. We specifically focus on a 230, 400 hectares region in north-central Wisconsin between 2003 - 2012. The auxiliary data collected from the satellite imagery of this region are relatively dense in space and time and can be used to efficiently predict how the forest condition changed over that decade. However, these records have a significant proportion of missing values due to weather conditions and system failures. To fill in these missing values, we build spaciotemporal models based on …

Diversification Across A Dynamic Landscape: Phylogeography And Riverscape Genetics Of Speckled Dace (Rhinichthys Osculus) In Western North America, Steven Michael Mussmann

Graduate Theses and Dissertations

Evolution occurs at various spatial and temporal scales. For example, speciation may occur in historic time, whereas localized adaptation is more contemporary. Each is required to identify and manage biodiversity. However, the relative abundance of Speckled Dace (Rhinichthys osculus), a small cyprinid fish in western North America (WNA) and the study species for this dissertation, establishes it an atypical conservation target, particularly when contrasted with the profusion of narrowly endemic forms it displays. Yet, the juxtaposition of ubiquity versus endemism provides an ideal model against which to test hypotheses regarding the geomorphic evolution of WNA. More specifically, it also allows …

Revision Of The Genus Monatractides (Parasitengona, Torrenticolidae) Of The United States And Canada: New Species, Re-Descriptions, Phylogenetics, And A Key To Species, Whitney Anne Nelson

Graduate Theses and Dissertations

The full suite of known Monatractides (Parasitengona, Torrenticolidae) taxa of North America (north of Mexico) are investigated herein using integrative methods. Species hypotheses are supported with morphology, geography, and phylogenetic analysis of the barcoding region of COI for 154 individuals from over 100 localities. Relationships between species are examined with a combined analysis of COI and 28S rDNA for 55 specimens. Previously described species are examined and re-described with color images and updated information, where possible. Our results indicate the need to synonymize two species: M. californica (Marshall, 1943) is a junior synonym of M. geographica (Marshall, 1943). We describe …

Keeping Pace With Relative Sea Level Rise: Marsh Platform Monitoring Shows Minimal Sediment Deficit Along The Louisiana Coast, Kelly Marie Sanks

Graduate Theses and Dissertations

Recent reports estimate that the marshes of the Mississippi Delta receive just 30% of the sediment necessary to sustain current land area1. An extensive monitoring campaign by the USGS and LCPRA provides direct measurements of sediment accumulation, subsidence rates, and deposit characteristics along the coast over the past 10 years2, allowing us to directly evaluate this sediment balance. By interpolating bulk density, organic fraction, and vertical accretion rates from 273 sites, a direct measurement of organic and inorganic sediment accumulation can be made. Results show that a total of 82 MT/year of sediment is delivered to the coast. Using a …

Zona Libre: Conservatism, Urban Growth, And The Rise Of The New Economy In The San Diego Borderlands, Daniel Elkin

Graduate Theses and Dissertations

Both the rise of conservatism as well as the neoliberal turn of the twentieth century have received much scholarly attention in recent decades. Often, these two subjects are examined separately, with the former focusing on questions of party realignment in the United States and the latter on global economic shifts toward privatization, finance, and the segregation of labor types across international boundaries. As a result, efforts to trace the dual movement between questions of domestic politics and international economy are left underdeveloped. “Zona Libre: Conservatism, Urban Growth, and the Rise of the New Economy” remedies this gap by exploring the …

The Cruel Consequences Of War: Life In Fauquier County, Virginia, 1861-1863, Madeleine Forrest Ramsey

Graduate Theses and Dissertations

“The Cruel Consequences of War” describes how the American Civil War came to Fauquier County, Virginia, a border area in northern Virginia, and examines the effects of the conflict on the county’s black and white residents from 1861 – 1863. Scholars have been writing community studies since the 1960s, but few have examined the region of northern Virginia. While the “traditional” war in Virginia has been studied extensively, the home front has not received as much focus. “The Cruel Consequences of War” helps to fill this void by detailing the wartime experiences of civilians, and the soldiers who occupied the …

Mumbai Macbeth: Gender And Identity In Bollywood Adaptations, Rashmila Maiti

Graduate Theses and Dissertations

This project analyzes adaptation in the Hindi film industry and how the concepts of gender and identity have changed from the original text to the contemporary adaptation. The original texts include religious epics, Shakespeare’s plays, Bengali novels which were written pre-independence, and Hollywood films. This venture uses adaptation theory as well as postmodernist and postcolonial theories to examine how women and men are represented in the adaptations as well as how contemporary audience expectations help to create the identity of the characters in the films. Ultimately, this project hopes to fulfil the gap in scholarship on adaptations in Bollywood.

Factors Influencing Adoption Of Conservation Agriculture In The Democratic Republic Of The Congo, Willy Mulimbi Byamungu

Graduate Theses and Dissertations

The agricultural sector in the Democratic Republic of the Congo (DRC) is still struggling to cope with its post-independence political and structural instability. From 1961 to 2000, the DRC experienced a decrease of 34% and 37% in daily caloric intake and protein intake, respectively. The DRC’s agriculture sector, led by women (who are the core of subsistence farming), is now being targeted as a potential pathway out of poverty through sustainable development programs. Empowering farmers to increase productivity by educating them to use conservation agriculture (CA), a more sustainable alternative to the traditional slash-and-burn agricultural practice, could contribute to reducing …

The Energy Yield Of Global Crops 1961-2016, Quinn Montana

Graduate Theses and Dissertations

It is often suggested that world food production must increase by 70%-100% or more by the year 2050 if we are to feed the anticipated world population at that time. To evaluate this claim, global crop production from 1961 to 2016 was inventoried using publicly available data from the United Nations Food and Agriculture Organization (FAO). To determine the adequacy of global crop output for humanity, annual global food crop production data (T y-1) were converted to energy yield in kilojoules (KJ y-1). These data were then compared to the annual metabolic energy requirement of the global human population. The …

Modified Landscapes, Esther Nooner

Graduate Theses and Dissertations

Modified Landscapes is a body of work that reflects serious thought regarding Nature and its future. My personal experience and beliefs are at the core of why I believe this subject to be of great importance and why it will sustain many artists’ investigations for the time to come. The influences that informed this process are explored through experiences I had traveling, reading and exploring the photograph as a material object. The manipulation of the photograph is meant to question the beautiful, untouched scene and break the Romantic gaze that is historically tied to representations of Nature and insist upon …

Real Goner, Nicholas Cox

Graduate Theses and Dissertations

The purpose of this thesis paper is to tell the story behind, and outline the theoretical and conceptual framework underlying the exhibition, Real Goner. The exhibition combines a number of elements drawn from music and art history, as well as the theoretical writings of Albert Camus, Guy Debord, and Joseph Kosuth. Together, these elements produce a cryptic exhibition that attempts to address the inherent chaos, and apparent meaninglessness of existence; and to see art as a proposition, a performance, and a practice. The exhibition addresses issues of celebrity, the production and consumption of culture, and where that cycle leaves us …

In the first paper, I have used the analytical hierarchy process to assign preliminary statistical weights to the most cogent variables influencing mass wasting …

Geography Of The Middle East Through The Western Lens: A Survey Of Films Set In The Middle East And Filmed In The American Southwest, Jake Bryan Rowlett

Graduate Theses and Dissertations

Representation of cinematic geography is a struggle in the world of film: a power balance between the work of the filmmakers and the place itself. Often, the filmmakers tip the scales in their favor and the true nature of the place is lost in translation. Throughout the history of cinema, the geography of the Middle East has been manipulated into a vision designed for Western audiences that is strikingly disjointed from reality.

The foundation of modern Orientalist interpretations of the Middle East in film can be seen in the early decades of the film industry, through the “Biblical Epic,” and …

Dicamba Effects On Soybean (Glycine Max) Growth, Yield, And Offspring, Mark Spencer Mccown

Graduate Theses and Dissertations

Introduction of a new dicamba-resistant (Xtend) trait in soybean and cotton will increase dicamba herbicide use. Consequently, concern for injury to sensitive crops from off-target movement and tank contamination will likely increase. For soybean, foliar symptoms associated with dicamba damage do not necessarily reflect yield losses; hence, experiments were conducted to determine the effects of dicamba on soybean growth, yield, and offspring. Low rates of dicamba [1/64X (8.75 g ae ha-1) and 1/256X (2.18 g ae ha-1) of a normal 1X field rate (560 g ae ha-1)] were applied at two vegetative growth stages (V4, V6) and at each reproductive …

Towards Quantifying Relevant Land Cover Change: A Case Study In The Central Flyway Of The Monarch Butterfly, Hanna Lenee Ford

Seeing Prehistory Through New Lenses: Using Geophysical And Statistical Analysis To Identify Fresh Perspectives Of A 15th Century Mandan Occupation, Amber Marie Mitchum

Graduate Theses and Dissertations

Great Plains prehistoric research has evolved over the course of a century, with many sites like Huff Village (32MO11) in North Dakota recently coming back to the forefront of discussion through new technological applications. Through a majority of its studies and excavations, Huff Village appeared to endure as the final stage in the Middle Missouri tradition. Long thought to reflect only systematically placed long-rectangular structure types of its Middle Missouri predecessors, recent magnetic gradiometry and topographic mapping data revealed circular structure types that deviated from long-held traditions, highlighting new associations with Coalescent groups. A compact system for food capacity was …
