Moral Responsibility And Other Visceral Attitudes Of Western Michigan University Students Toward Food Waste, Quinn Heiser
Moral Responsibility And Other Visceral Attitudes Of Western Michigan University Students Toward Food Waste, Quinn Heiser
Masters Theses
Despite the large number of people that go hungry on a regular basis in America, food waste remains a looming issue, globally and nationally. Both American college students and the universities themselves contribute a large portion to the national food waste totals. A dichotomy that is especially curious is the difference between students who live on-campus and whose main source of meals is the dining centers, versus students who live off campus and rely mainly on groceries to make meals independently. However, food waste has seldom been studied in the context of the fact that college is a major transition …
Factors Affecting Groundwater Nitrate Concentration In Madinah Area, Saudi Arabia, Majed M. Almutairi
Factors Affecting Groundwater Nitrate Concentration In Madinah Area, Saudi Arabia, Majed M. Almutairi
Masters Theses
High levels of nitrate in groundwater are a serious problem in Madinah Area, Saudi Arabia. Identifying factors affecting groundwater nitrate contamination is important for managing groundwater quality. This study examined factors that have significant impacts on the high level of groundwater nitrate in Madinah Area. Factors examined included well-depth and land cover. Relationships between variables were explored using three statistical approaches: the Kruskal-Wallis test and two types of regression (ordinary least squares [OLS] and geographically weighted regression [GWR]).
Nitrate concentration data show that 73% of obtained groundwater samples exceeded the United States Environmental Protection Agency (EPA) maximum contaminant level (MCL) …

Analysis Of Interdunal Wetlands And Ecosystem Dynamics Using Uas And Obia In Ludington State Park, Michigan, Claire Gilbert
Masters Theses
The Great Lakes sand dunes are the world's largest freshwater dune complex. There is a functional relationship between coastal wetlands and freshwater sand dune, referred to as interdunal wetlands. Interdunal wetland systems are highly dynamic and change dramatically seasonally and annually. Using geographic information systems (GIS) and unoccupied aerial systems (UAS), this thesis project is focused on understanding the spatial distribution of sparse and dense vegetation, and abiotic influence such as distance to coast, slope, and aspect influence interdunal wetland stability within a Great Lakes shoreline dune system. Object-based image analysis (OBIA) classification results extracted meaningful vegetation densities of growth …
Using Historical Maps For Contaminated Site Identification And Prediction, And Environmental Justice Implications: A Case Study In Grand Rapids, Michigan, Dana Heusinkveld
Using Historical Maps For Contaminated Site Identification And Prediction, And Environmental Justice Implications: A Case Study In Grand Rapids, Michigan, Dana Heusinkveld
Masters Theses
As the production of synthetic chemicals has grown in the past centuries to increase production, lower costs, and generally make our lives more convenient, detecting and understanding the environmental impacts of these compounds has lagged significantly behind their mass production and wide-spread use. To combat this trend, sources of these contaminants, especially those that have been removed from the landscape, need to be quickly identified to make mitigation and remediation efforts more effective. In this study, historical Sanborn maps are used to extract and digitize historical site/land use in Grand Rapids during the early 1900s through the practical application of …

Interannual Variations Of Snowfall In The Lower Peninsula Of Michigan And Impacts Of Local And Remote Meteorological Conditions, Nirjala Koirala
Masters Theses
Inter-annual variation of snowfall and its relation to climate indices will help clarify and improve the prediction of total snowfall in the Lower Peninsula of Michigan (LPM). This study examines the trend and variability of annual snowfall (November- March) using 8 homogeneous weather stations in the LPM. The statistical relationship between snowfall and air temperature, Sea Surface Temperature (SST), North Atlantic Oscillation (NAO), Pacific Decadal Oscillation (PDO) and Maximum Ice Coverage(MIC) of Lake Michigan is calculated. The long-term trend in the snowfall data set from 1950 to 2015 is removed before any statistical correlation analysis is conducted. My analysis suggests …

Modeling Channel Response To Dam Removal In Lansing, Michigan, Using Swat, Ryan Filbin
Masters Theses
The removal of dams has increased in recent decades in the United States, largely resulting from decaying infrastructure and greater efforts to restore rivers to a more natural, free-flowing state. Dam removal presents the opportunity for increased public safety, improved environmental prosperity, and improved economic prosperity in conjunction with riverfront revitalization projects. The City of Lansing, Michigan, contains two moderate-to high-risk dams along the Grand River that pose a significant risk to the surrounding area in the event of structural failure.
The Soil and Water Assessment Tool (SWAT) is applied to model the impacts of the Moores Park Dam and …
Michigan's Clay Bluffs: The Description And Comparison Of An Erosion-Dependent Natural Community, Nathaniel G. Fuller
Michigan's Clay Bluffs: The Description And Comparison Of An Erosion-Dependent Natural Community, Nathaniel G. Fuller
Masters Theses
The clay bluffs of Michigan are a natural community found along the shores of the Great Lakes. Groundwater is found to be critical to sustaining the alkaline wetlands on the face of the bluff as well as the source of most erosion events. The clay bluffs are unusual in their vegetation, disturbance regime and geographical context. This thesis focuses primarily on describing seeping clay bluffs and exploring the comparison to other natural communities. The purpose of this is twofold, to better understand the ways in which natural communities are described as distinct from one another, and to assess the distinctness …

Predictive Modeling In The Search For Vertebrate Fossils: Geographic Object Based Image Analysis (Geobia) In The Eocene Of Wyoming, Bryan Bommersbach
Masters Theses
The development and testing of predictive models for identifying productive fossil localities represents a promising interdisciplinary endeavor among geographic information scientists, paleoanthropologists, and vertebrate paleontologists. This thesis analyzed high resolution (2m spatial resolution) commercial satellite imagery from the Worldview-2 satellite of five areas of the Great Divide Basin using a GEographic Object-Based Image Analysis (GEOBIA) technique, which segments the image into spectrally homogeneous, multi-pixel image objects. In addition to allowing statistical analysis of the spectral characteristics of the image objects, GEOBIA techniques also let analysts incorporate expert knowledge and contextual information to improve classification accuracy. The spectral characteristics of the …
Owning Our Food System: Urban Community Gardening And Local Food Movements, Paige A. Edwards
Owning Our Food System: Urban Community Gardening And Local Food Movements, Paige A. Edwards
Masters Theses
Food is a means of examining culture, including identity, autonomy and power. It creates relationships and memories between people via shared connections. Through food, I explore local food movements and urban community gardening.
We both ingest and produce garden-grown foods. This movement is often described as simple nostalgia. I suggest that it is a response against heavily processed foods within a system reliant on mass produced food. This desire for ownership pushes community gardens and other counter-hegemonic spaces forward in their goals of using social practice to challenge the established food industry and take control within their own lives.

No Fracking Way! A Study On The Spatial Patterns Of And Changes In Perception And Distance From A Michigan Horizontal Hydraulic Fracturing Site, Shannon Mcewen
Masters Theses
The research investigates whether Michigan residents' perception of risk from an oil and natural gas (ONG) well site that employs the use of horizontal hydraulic fracturing (fracking) changes with distance. The research goal is to determine if residents that live farther from a fracking site perceive it to be more dangerous than those who live closer. Secondary research goals include determining if increasing distance from a fracking site cause residents to overestimate their proximity to a fracking site and if gender and education levels have an effect on residents' perception levels. Data were collected from residents in three counties in …

Study Of Feasability For Phase Difference Extraction Using Software Defined Radio In Location Analysis, Paul Miller
Masters Theses
Here is a method for using the phase of an HF radio signal for use in location analysis. This computation is implemented in a software defined radio processing block in the GNU Radio environment. The signals analyzed are received by an Ettus Research USRP SDR. We created a phase analysis system called WMU Rootsync, which compares the roots of a received signal to the roots of a generated reference signal for the phase analysis. This research describes a prototype method for phase analysis only. Future projects may use these ideas differently than presented here. We intend for future projects to …
Ethical Ambivalence In Local Television Weathercasting: A Rossian Analysis, Vernon Keith Thompson
Ethical Ambivalence In Local Television Weathercasting: A Rossian Analysis, Vernon Keith Thompson
Masters Theses
Today’s television weathercasters are being called upon increasingly to go beyond benign weather prognostications to become the “newsroom experts” for science topics. The expectation to act as both scientists and journalists can cause ethical ambivalence (EA), a sociological condition in which, faced with conflicting norms, the subject feels that he/she is being pulled psychologically in two different directions (Jansen & Von Glinow, 1985). This thesis presents a Rossian analysis of climate change in weathercasting, a topic that captures the most important ethical tensions arising from conflicting duties within the weathercaster role, specifically: a) how might the duties of the television …

The Effects Of Replacing Dispersed Trash And Recycling Bins With Integrated Waste Receptacles On The Accuracy Of Waste Sorting In An Academic Building, Katherine J. Binder
The Effects Of Replacing Dispersed Trash And Recycling Bins With Integrated Waste Receptacles On The Accuracy Of Waste Sorting In An Academic Building, Katherine J. Binder
Masters Theses
Numerous researchers and theorists have attempted to explain the existence of the gap between the possession of environmental knowledge and awareness and the display of pro-environmental behavior (Glasser, 2007; Kollmuss & Agyeman, 2002). Behavior analysis is uniquely aligned to contribute to this discussion through its emphasis on the role of controlling variables in behavior change. A growing number of behavioral research studies address the challenges of group-contingencies in an effort to solve real-world gaps (Lehman & Geller, 2004). This study was designed as a continuation of the line of behavioral research designed to increase recycling rates and also as an …
Geophysical And Remote Sensing Applications For A Better Understanding Of The Structural Controls On Groundwater Flow In The Lucerne Valley, California, Dale R. Dailey
Masters Theses
An integrated study was conducted in the Mojave Basin to investigate the potential role of faults and basement uplifts for groundwater flow in the Mojave Desert. Observations made include: 1) Very Low Frequency (VLF) measurements across mapped (using LIDAR and Geoeye-1 imagery) fault traces showed significant radio field dip angles indicative of presence of shallow sub-vertical, sheet-like conductors; many of the VLF tilt peaks coincided with changes in the magnetic profiles; 2) Vertical Electric Soundings indicate shallow basement west of, and parallel to, the Helendale Fault and deep saturated zones east of the fault/basement outcrop (F/B); and 3) isotopic analyses …

An Investigation Of The Surface Temperature Distribution In The Detroit Region, Allen R. Smith
An Investigation Of The Surface Temperature Distribution In The Detroit Region, Allen R. Smith
Masters Theses
Chapter I
Introduction
Climate and the City
Studies made of temperature in and around cities have shown the climate of the city to be anomalous in relation to its regional climate. The extent of this anomalous condition and the reasons for its occurrence vary from city to city and from season to season. So many variable factors are present in the generation or regeneration of heat within the city that no study has yet satisfactorily explained the total factors involved, or has indicated the percentage for which any one factor might be responsible. This being the case, the only objective …
