Spatiotemporal Distributions Of Sargassum On Grand Cayman, Graeme Timmeney

Masters Theses

This mixed methods research examines individual perceptions of Sargassum on Grand Cayman’s beaches in 2020 using participant mapping, and semi – structured interviews. Results from the participant mapping are compared to satellite detection of sargassum. Sargassum poses health risks to both humans and the natural environment. Decaying Sargassum produces sulfuric gas and prevents young turtle hatchlings from reaching the ocean. Since 2011, Sargassum has diffused beyond the Sargasso Sea into entirely novel locations, spanning from the west African Coast to the Gulf of Mexico. Increased biomass has proven to be overwhelming for many Caribbean Islands, including Grand Cayman where hundreds …

Strong Women Breaking Ground: Roles Of Women In Agriculture In Michigan, April L. Shirey

Masters Theses

Agriculture in Michigan is changing. While the number of farms and farmers continue to decrease, women are increasingly taking on the role of farmer instead of the “farmer’s wife”. The number of female producers increased from 8,275 to 26,059 where the number of producers in Michigan decreased from 56,014 to 47,641 from 2007 to 2017 (USDA, 2007, 2017). Women are becoming the face of farming in Michigan, yet little research examines the impacts of these shifts. In this research, I conduct semi-structured interviews with female farmers throughout lower Michigan beginning in the summer of 2020 to learn more about these …

Particularly, it fills the gap that is blaming HMO (Houses in multiple occupation) …

Social Inequity In Memories Of Shakespeare: The Fetishizing Power Of The Globe Theatre, Reagan A Yessler

Masters Theses

William Shakespeare’s works are widely regarded as the pillar of English literature in Western society. An understanding of Shakespearean literature is a form of symbolic or cultural capital, and a lack thereof signals that a person is uncultured, uneducated. However, in his own time, Shakespeare was not so highly regarded. To fully understand the evolution that Shakespeare and his works have undergone, one must consider the modern memory politics that reify the contemporary interpretation of Shakespeare in the Western world at liex de memoire (places of memory), which are shaped by the tumultuous sequence of historical movements that formed Shakespeare’s …

Association Between Stream Impairment By Mercury And Superfund Sites In The Conterminous Usa, Karessa L. Manning

Masters Theses

Mercury is a natural element that can cause harm to the brain, heart, kidneys, lungs, and immune system, especially to fetuses developing in the womb.

"Optimizing water use is a growing concern, especially in agricultural communities where water use is high. An important challenge in agricultural water optimization is knowing when and where crop water stress is occurring, particularly on large scales where in-situ measurements are no longer practical to obtain. In an effort to combat this challenge, this study utilizes remotely sensed evapotranspiration (ET) and Normalized Difference Water Index (NDWI) to evaluate the responses of integrated satellite datasets to water-stressed conditions over fields of irrigated corn, irrigated winter wheat, and rainfed winter wheat from 2007 to 2017 in southwestern Kansas. Using two different ET …

How Can Employers Contribute To Reducing Commuter-Generated Carbon Emissions? Evaluating Employer-Provided Commuter Benefits In Cambridge, Ma, Mary Richards

Masters Theses

Encouraging a more sustainable commuter mode shift and improving urban transportation systems have the potential to reduce anthropogenic greenhouse gas emissions (GHGs), a major contributor to climate change. Replacing some single-occupancy vehicle (SOV) trips with alternative modes of transportation, such as public transit, walking, or bicycling, represents one approach to begin reducing transportation-related emissions. Collectively, these shifts in transportation patterns would help to reduce the negative social, economic, and environmental costs associated with high rates of personal vehicle use. Employer-provided benefits programs have the potential to influence commuter behavior by making sustainable, alternative commuting choices a more convenient and economically …

Enforcing Higher Standards For Flood Hazard Mitigation In Vermont, Tamsin Flanders

Masters Theses

The state of Vermont faces increasing risk of costly damage from catastrophic flooding events as climate change increases the frequency of heavy rains and cumulative precipitation. In addition to increasing flood inundation risk, extreme precipitation events are leading to high rates damage from fluvial erosion—erosion caused by the force of floodwater and the materials it carries. As in all U.S. states, flood hazard governance in Vermont is shared by multiple levels of government and involves a complex compliance model that relies on local governments to regulate private property owners to achieve community, state, or federal goals.

An Evaluation Of Unmanned Aerial Systems And Structure-From-Motion For Fluvial Large Wood Sensing And Risk Assessment, Daniel Gerke

Masters Theses

This research aims to show Unmanned Aerial System (UAS) and Structure-from-Motion (SfM) technology can, in combination, improve on traditional large wood (LW) monitoring techniques. More temporally and economically efficient data collected at a finer spatial resolution and greater spatial extent will increase the effectiveness of management plans and risk assessment for LW by providing decision-makers with a complete picture of the river.

Contemporary practices are too inefficient in time and labor for large-scale monitoring of fluvial LW with anything more than the most general management or risk assessment in mind. The paradigm of river research, the river continuum concept (RCC), …

Planning For Industrial Land And Industrial Jobs: An Evaluation Of New York City's Industrial Business Zone Program, Jennifer Davis

Masters Theses

In recent years, industrial preservation policies, which aim to preserve urban industrial activity and industrial employment often through the preservation of industrial land, have emerged as a flashpoint in cities across the country that have implemented these policies. While critics contend that industrial preservation policies amount to smokestack chasing in “post-industrial” cities like New York City, industrial preservationists argue that such policies help to preserve well-paying, middle-class jobs and thus represent a tool to mitigate rising income inequalities in cities. Despite considerable attention to these policies, minimal research has evaluated the effectiveness of industrial preservation policies as land use and …

Sustainable transportation planning focuses on addressing the needs of current users, without jeopardizing the needs of future users (Black 1997, Richardson 1999, Balsas 2003). A popular mode of sustainable transportation is the bicycle, which is frequently used by college students. One aspect of bicycle transportation that remains underexplored within the United States and on university campuses, is bicycle parking. By using rack conditioning assessments, bicycle theft density analysis, bicycle parking counts and a formative stakeholder survey of the bicycle parking at Western Michigan University’s campus, recommendations were able to be created for campus officials for use in their planning efforts. …

Habitat Suitability Of The Mountain Pine Beetle In Alberta, Canada Under Future Climate Scenarios, Nathalie Woloszyn

Masters Theses

Mountain pine beetle (Dendroctonus ponderosae Hopkins) is the most destructive insect currently devastating North American forests (Safranyik & Carroll, 2006). Native to western North America, the mountain pine beetle has recently expanded beyond its historic range, into the novel territory of Alberta, Canada. Since its arrival in the mid-2000s, the mountain pine beetle has diffused eastward at an average rate of 80km/year (Cooke & Carroll, 2017). Poised at the doorstep of the boreal forest, current concern anticipates the potential diffusion of the mountain pine beetle to eastern North America.

Understanding Individuals’ Perceptions Of Oak Wilt And Its Implications For Invasive Species Management, Matthew Morrissey

Masters Theses

Oak wilt, a thought-to-be exotic, invasive fungal disease preys upon oak tree species (Quercus sp.) and has begun to cause die-off in oak stands throughout the state of Michigan, with potential for increased cases and subsequent death. Despite efforts to treat the disease, there is no guaranteed treatment for already-infected oak trees. The best option is to control the infection and prevent its spread, by methods such as disconnection of root systems, removal of infected trees, and informed pruning. Given that humans play a role in oak wilt’s artificial spread, it is imperative that the public understands their …
