The Determinants Of Municipal Minimum Wage Ordinances: An Analysis Of 100 Large Cities From 2012-2017, Nicholas S. Hilton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The city of Seattle, Washington made headlines in 2014 when its city council enacted the highest minimum wage in the history of the United States. The ruling appeared to begin a trend as similar policies began diffusing in cities across the country. In reality, however, municipal minimum wage ordinances have existed since the early 1990’s. Yet, despite over two decade’s worth of data on the subject, little research has been conducted to understand the characteristics that influence cities to enact minimum wages in the first place. This study contributes to our understanding of the predictors of minimum wage ordinances by …

Enteric Methane And Nitrogen Emissions In Beef Cattle Grazing A Tannin-Containing Legume Relative To Feedlot And Traditional Pasture-Based Production Systems, Raúl David Guevara Ballesteros

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Beef cattle production is highly criticized because of the high use of land and water resources, and by the pollution (e.g., the gas methane in a cow’s breath and nitrogen in urine) produced by cows fed in feedlots. In contrast to feedlots diets and grasses, some plants (e.g., legumes) contain bioactive compounds (condensed tannins) that reduce pollution and enhance animal nutrition. In my research, I observed that cows grazing a tannin-containing legume (birdsfoot trefoil; BFT) had methane emissions similar to cows fed a feedlot ration with comparable weight gains. Cows in the BFT treatment gained more weight than cows grazing …

Evaluation Of Stream Bank Restoration To Improve Water Quality In A Semi-Arid Stream, Johnathan Neenan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Human watershed activities such as converting land cover to agriculture and livestock grazing have negatively impacted stream water quality worldwide. One such case is Utah’s Upper Sevier River where a loss of woody bank vegetation (reduced shading) and accelerated bank erosion (increased fine sediment inputs) has led to increased stream temperature and water turbidity. As a result, the state of Utah sought to improve water quality conditions using streambank restoration. While commonly recommended and performed, the effectiveness of this sort of restoration has rarely been quantified. Here, I evaluated a restored reach of the Upper Sevier River near Hatch, UT …

Boundaries And Bridges In Rangeland Social-Ecological Systems: Studies Of Collaboration, Innovation, And Information Flow, Gwendŵr R. Meredith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Public rangelands are managed by a mixture of federal, state, and local governments. Often, these groups are charged with managing adjacent lands that are part of the same greater landscape. To do this effectively, communication and collaboration is required. This dissertation examines federal, state, and local agencies’ level of communication through three projects.

The first project examined barriers to agencies adopting management tools from each other.
