Correlational Analysis Of Mammals And Residential Land Use: Amherst, Ma, Ella Gutkowski

Massachusetts GIS Day

Mammal diversity varies in different types of land uses. Residential land use oftentimes interferes with the natural occurrence of mammal species. This study conducts a correlational analysis using camera trap data from Excel and land use data in GIS to uncover whether humans have disrupted mammal occurrence in residential land use areas in Amherst, MA. Results reveal that human activity in residential land use areas in Amherst did not strongly influence the occurrence of these mammals.

Understanding The Safety Impacts Of Left-Turn Infrastructure On The Vulnerable Driving Population, Francis Tainter

Doctoral Dissertations

The severe impact of roadway fatalities has remained a significant concern for researchers in recent years. As of 2015, traffic fatalities were the leading cause of death for individuals between the ages of 15 and 20 years old and a significant safety concern for drivers over the age of 65 years old (otherwise known as the “vulnerable” driving population). Intersection-related crashes have also remained prevalent in these demographic categories. Through four primary crash data evaluations, this dissertation explores the safety implications on the “vulnerable” driving population in the Commonwealth of Massachusetts. Through the utilization of newly developed crash data linkage …

First Records Of Perdita Bequaerti (Hymenopertera: Andrenidae) From New England, Justin C. Roch, Deicy Carolina Muñoz Agudelo, Lynn S. Adler, Joan Milam

Environmental Conservation Faculty Publication Series

We document the first New England records of the bee Perdita bequaerti Viereck. Perdita bequaerti is a specialist on Asteraceae flowers, especially Helianthus, and is native to much of eastern North America, where it is often associated with predominantly sandy habitats. Previous records indicated P. bequaerti reached the northeastern extent of its range in the state of New York, but in August 2019, during a survey of bees on Helianthus, we collected five specimens of P. bequaerti at two sites in western Massachusetts. Both sites were located on small-scale farms with abundant non-native Helianthus, on soils characteristic …

Who Bears The Burden? Racial Disparities In Confirmed Cases Of Covid-19 In The Greater Boston Area, Leija Helling

Massachusetts GIS Day

Documenting racial disparities in the spread of COVID-19 is crucial to bettering public health. In the Boston area, non-white and Black communities are significantly overrepresented in areas of high confirmed COVID-19 prevalence. Areas where high prevalence is clustered (“hot spots”) have disproportionate shares of non-white and Black residents, and the disparities are statistically significant. These results confirm marked COVID-19 racial disparities in Boston.

Processes, Patterns, And Predictions Of Soil Moisture Variation In Upland And Peatland Cranberry Farms In Massachusetts, Rebecca Brennan

Masters Theses

The American Cranberry (Vaccinium macrocarpon Ait.) represents a vital sector of the economy of southeastern Massachusetts. Due to the hydrogeological and edaphic characteristics of peatlands, variations in soil drainage and soil moisture represent major management challenges for growers in Massachusetts. An emerging trend of upland (mineral soil) cranberry farms planted with new hybrid cultivars has the potential to enhance the profitability and long-term viability of cranberry production in Massachusetts. However, sparse data exist on soil moisture characteristics of peatland and upland cranberry farms. The purpose of this research was to elucidate the differences in soil moisture between upland and …

Footing The Bill: An Empirical Look At The Correlation Between Campaign Contributions And Councilor Votes On Split Tax Rates In Massachusetts, Tristan Laliberte

Masters Theses

The current literature regarding the relationship between campaign contributions and roll call voting by elected officials has primarily focused on the congressional level. This study begins to fill the holes in this topic by utilizing city councilor contributions from likely business owners and their stance on tax classification in their respective communities. In this study, I examine contribution data from municipal officials in fourteen communities in Massachusetts as well as the expressed opinions made by city councilors in the 2018 tax classification hearings in order to test the theories that (1) there is a correlation between the actions of political …

Experimental Assessment Of The Current Load Rating Procedures For A Corroded Steel Ridge Girder In Massachusetts, Brendan T. Knickle

Structural Engineering Masters Projects

The work conducted for this project involves an experimental assessment of the Massachusetts Department of Transportation’s (MassDOT) existing procedure for determining the resistance of a corroded steel girder end when load rating a bridge. Three steel girders with significant corrosion developed over a 79-year service life were obtained from a recently rehabilitated bridge and loaded to determine the girders corroded resistance. A testing rig was designed in the UMass Amherst Brack Structural Testing Laboratory to both apply a shear dominated load to the corroded girder and withstand the developed lateral loads throughout the analysis. Reaction force data obtained from the …

Spatial And Temporal Mapping Of Distributed Precipitation, Surface And Groundwater Stable Isotopes Enables Insights Into Hydrologic Processes Operating At A Catchment Scale, Alison Cole

Masters Theses

Isotopic analyses of d¹⁸O and d²H of water through the hydrologic cycle have allowed hydrologists to make better interpretations related to climate and relationships between precipitation, surface water, and groundwater. In this study 394 precipitation samples 1917 surface water samples and 1405 groundwater samples across Massachusetts was used to create an isoscape for each respective water. All samples have been collected by volunteers throughout Massachusetts. A state meteoric water line: d²H = 7.7*d¹⁸O + 9.8, surface water line: d²H = 5.7*d¹⁸O – 4.2, and groundwater line: d^{2 …}

Hydrologic Structure And Function Of Vernal Pools In South Deerfield, Massachusetts, Charlotte Axthelm

Masters Theses

Vernal pools are small, ephemeral wetlands lacking an inlet or outlet. These wetlands, also known as seasonal pools, are found in a wide range of biomes, and their characteristics vary based on location. While the vegetation of western U.S. pools, and amphibians of eastern U.S. pools have been extensively studied, many aspects of vernal pools have not been fully characterized. In particular, although the general seasonal wetting and drying cycle is understood qualitatively, few studies have attempted to quantify the hydrological regime of vernal pools in New England. As water level variation drives many, if not all, of the characteristics …

The History Of Massachusetts Transfer And Articulation Policies In Contexts Of Evolving Higher Education System Structure, Coordination, And Policy Actors, Daniel De La Torre, Jr.

Doctoral Dissertations

Community colleges carry out dual missions providing occupational and collegiate preparation in local communities across the United States. These institutions prepare students for advanced study via transfer policies that lead to enrollment in baccalaureate institutions. State higher education systems use transfer and articulation policies to strengthen academic pathways between two-year and four-year institutions. These policies rely on established governance to facilitate student transfer between sectors. The transfer and articulation literature stresses the importance of statewide policy guidelines, yet little has been written about the process of transfer policy development involving state higher education governance and policy groups and actors. The …

Performance Of Floristic Quality Assessment In Massachusetts Forested Wetlands, Carolyn Gorss

Masters Theses

In order to combat the loss of valuable wetland functions and services, federal, state and tribal governments must have the tools to accurately assess and monitor the condition of wetland ecosystems. One particular method of wetland assessment is Floristic Quality Assessment (FQA), which has been growing in popularity throughout the United States since its creation in the 1970s. FQA relies on vegetative indicators of human disturbance to assess the integrity of an ecosystem. FQA calculations are based on Coefficients of Conservatism (C-scores), professionally-assigned scores ranging from 0-10 that denote a local species' tolerance to anthropogenic disturbance. Despite increasing interest in …
