The Intersection Of Gentrification, Race, And Historical Sociology: Utilizing The Construction Of A Racial Gentrification Index To Measure Racialized Versus Economic Changes Across Massachusetts From 2000 To 2020, Paige Elizabeth Depasquale

Master's Theses and Capstones

The phenomenon of gentrification occurs in cities and towns across the United States in a racialized way. Despite several gentrification indices existing, thus far none measure racial gentrification nor incorporate racialized practices associated with gentrification into their measures. This paper aims to create a novel index measuring racial gentrification across 73 cities and towns in Massachusetts from 2000 to 2020 using Census and Diversity and Disparities data. The racial gentrification index constructed comprises of 3 economic gentrification variables and 6 residential segregation variables. Through multiple linear regression analyses, racial gentrification is tested as a predictor of three structural outcomes that …

Spac Mergers, Ipos, And The Pslra's Safe Harbor: Unpacking Claims Of Regulatory Arbitrage, Amanda M. Rose

William & Mary Law Review

Communications in connection with an initial public offering (IPO) are excluded from the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995 (PSLRA). Unsurprisingly, IPO issuers do not share projections publicly—the liability risk is too great. By contrast, communications in connection with a merger are not excluded from the safe harbor, and special purpose acquisition companies (SPACs) routinely share their merger targets’ projections publicly. Does the divergent application of the PSLRA’s safe harbor in traditional IPOs and SPAC mergers create an opportunity for “regulatory arbitrage” and, if so, what should be done about it? …

Gentrification And Crime In The Twin Cities: Insights And Challenges Through A Statistical Lens, Erin G. Franke

Mathematics, Statistics, and Computer Science Honors Projects

Gentrification is a complex process of urban redevelopment that typically involves an in-migration of educated people to neighborhoods experiencing a period of disinvestment. While gentrification is widely regarded for its potential to displace long-time businesses and residents of the neighborhood, its impact on crime is highly controversial. There is not a consensus on the relationship between gentrification and crime across criminological theory and past statistical studies have also shown contradictory results. Measuring gentrification on the tract level with census data, we seek to understand gentrification’s relationship with violent crime and theft in the Twin Cities. Using a Poisson model with …

Sweet Potato In The Lower Rio Grande Valley: Evaluating Performance Across Several Cultivars, Jon Dale

Men, Women, And Italians: The Masquerade Of Narrative And Identity In Richardson's Sir Charles Grandison, Ruth A. Holmes

English Theses & Dissertations

The chaotic masquerades that proliferated during the British long eighteenth century punctuated the period’s preoccupation with order and categorization. The identity categories that the masquerade disrupted, the novel reinforced, or perhaps even created. It was in the middle of this period, in the political center of Britain, that Samuel Richardson published his third and final novel, The History of Sir Charles Grandison (1753), a novel which centers England and was also centered by England, a national treasure entangled in literary and cultural history. Tracing the nexus of gender and nationalism in Grandison then becomes important given the novel’s active entanglement …

In the efforts to limit hazard risk exposure, local governments are increasingly planning for long-term flood protection. One prospective flood risk mitigation measure is living shorelines or nature-based adaptation. The coastal ecosystems, such as beaches, wetlands, barrier islands, oyster reefs, and salt marshes, deliver multiple benefits to communities, including recreation, natural resources, freshwater, and carbon sequestration. Moreover, when combined with structural solutions, they can effectively reduce water …

Management Of Nematodes Associated With Tobacco And Sweet Potato Using Non-Fumigant Approach, Md Shah Alam

All Theses

Tobacco and sweet potato are attacked by several species of plant-parasitic nematodes leading to substantial yield losses. Because host-plant resistance is lacking in commercial cultivars and other common methods of nematode management either have low efficacy or pose adverse effects to the environment, controlled environment studies were conducted to evaluate the efficacy of non-fumigant chemical and biological nematicides against Meloidogyne enterolobii on tobacco and Rotylenchulus reniformis on sweet potato. Results suggest that fluensulfone was the most effective in suppressing M. enterolobii in tobacco, followed by oxamyl and fluopyram. The biological Burkholderia derived biological nematicide did not suppress the nematode population. …

Limited Evidence Of Cumulative Effects From Recurrent Droughts In Vegetation Responses To Australia's Millennium Drought, Tong Jiao, Christopher A. Williams, Martin De Kauwe, Belinda E. Medlyn

Geography

Drought-induced vegetation declines have been reported across the globe and may have widespread implications for ecosystem composition, structure, and functions. Thus, it is critical to maximizing our understanding of how vegetation has responded to recent drought extremes. To date, most drought assessments emphasized the importance of drought intensity for vegetation responses. However, drought timing, duration, and repeat exposure all may be important aspects of ecosystem response with the potential for non-linear effects. Cumulative effects are one such phenomenon, representing the additional decline due to repeated exposure to drought, and indicating gradual loss of ecosystem resistance. This study quantifies the frequency …
