    Property, Identity and Place in Seventeenth-Century New England

    Abstract This thesis presents a study of the construction and defence of English settler-colonies in New England during the seventeenth century, focusing upon the relationship between ordinary people and their environment. This work initially examines the preexploration reports and the first few decades of settlement and how commodification and naming practices helped in translating the landscape into a familiar, useful and, most importantly, English place. This continues in Chapter Two with a study of the distribution and construction of towns, boundaries and familiar patterns of agricultural usage. This patterning reveals how early settlers perceived their world, and how they secured traditional English customs and patterns onto this uncultivated landscape. The final two chapters will examine challenges to this system, from within New England and across the Atlantic. Chapter Three focuses on the challenge of native land rights, which threatened to undermine the initial basis of conquest and discovery as claims to the land. However, this was overcome due the flexibility of narratives of ownership and possession and the addition of native land rights to English property regimes. Chapter Four examines the network of authority and ownership which crossed the Atlantic and throughout New England, and what happened when these systems and ideas were challenged by the creation of a new government under the Dominion of New England. This final chapter reveals how all of these concepts and themes about property wove together to re-create the relationship between English settlers and their land, albeit through new concepts and methods

    Examining the Relationships Among Working Memory, Creativity, and Intelligence

    In this study we investigated the relationships among working memory, creativity (measured as divergent thinking and creative achievement) and nonverbal intelligence. Furthermore, this study examined the roles of working memory and intelligence in the creative process. In order to examine this, participants were evaluated using a variety of cognitive tasks that included the Alternative Uses Test, the Consequences Task, the Creative Achievement Questionnaire, the Alloway Working Memory Assessment, and the matrix test from the Wechsler Abbreviated Scale of Intelligence. The results of this study indicate that verbal working memory was related to divergent thinking over and beyond intelligence and creative achievement. Nonverbal intelligence was found to be related to divergent thinking over and beyond working memory. Finally, according to the model used in this study, creative achievement was the best predictor of divergent thinking. The findings of this study expand on the previous literature pertaining to the relationships between working memory, creativity and intelligence

    Spatially restricted drivers and transitional cell populations cooperate with the microenvironment in untreated and chemo-resistant pancreatic cancer

    Pancreatic ductal adenocarcinoma is a lethal disease with limited treatment options and poor survival. We studied 83 spatial samples from 31 patients (11 treatment-naïve and 20 treated) using single-cell/nucleus RNA sequencing, bulk-proteogenomics, spatial transcriptomics and cellular imaging. Subpopulations of tumor cells exhibited signatures of proliferation, KRAS signaling, cell stress and epithelial-to-mesenchymal transition. Mapping mutations and copy number events distinguished tumor populations from normal and transitional cells, including acinar-to-ductal metaplasia and pancreatic intraepithelial neoplasia. Pathology-assisted deconvolution of spatial transcriptomic data identified tumor and transitional subpopulations with distinct histological features. We showed coordinated expression of TIGIT in exhausted and regulatory T cells and Nectin in tumor cells. Chemo-resistant samples contain a threefold enrichment of inflammatory cancer-associated fibroblasts that upregulate metallothioneins. Our study reveals a deeper understanding of the intricate substructure of pancreatic ductal adenocarcinoma tumors that could help improve therapy for patients with this disease

    Seasonality, Labor Organization, and Monumental Constructions: An Otolith Study from Florida’s Crystal River Site (8CI1) and Roberts Island Shell Mound Complex (8CI40 and 41)

    In recent decades, archaeological research has provided evidence that some mounds in the southeastern United States were constructed in short episodes. A large work force would have been required to accomplish these monumental projects. Shell mounds, in particular, provide an opportune type of architecture to investigate whether seasonal aggregations of laborers gathered at sites to engage in large-scale work projects because these mounds are constructed of aquatic resources that leave signatures for what time of the year they were caught or harvested. This study investigates whether the residents of the Crystal River site (8CI1) and Roberts Island (8CI40 and 41) on Florida\u27s Gulf Coast were participating in seasonal deposition events involving the construction of monumental architecture and if feasting acted as a mechanism to attract the needed labor force. Marginal increment analysis is performed on red drum (Sciaenops ocellatus) and spotted seatrout (Cynoscion nebulosus) to determine what time of year these fishes were and eventually deposited in midden and mound contexts

    Effectiveness of Hints vs. Complete Explanation using ASSISTments

    A comprehensive set of measurement problems was created with identical tutoring content presented to students in one of two ways: Hints or Complete Explanations. A study was run using these problems sets to determine which type of tutoring is more effective. Students were randomly assigned one type of tutoring for each problem set that they attempted. We were able to conclude that Hints tutoring was more effective for area, perimeter, surface area, and volume problems. Complete Explanations were more effective for unit conversion problems. Students were less likely to be able to master Complete Explanation problems than Hints problems. Further analysis is required to determine if student ability has an effect on the most effective tutoring strategy
