Realist depictions of bad housing are pervasive in the canon of twentieth-century American literature. Insufficient abodes crisscross the literary map of the United States, appearing regularly in settings from New York to Los Angeles and from Alaska to Florida. This dissertation examines three case studies that themselves crisscross the map, and represent the diverse contexts of this common thematic concern. Anzia Yezierska writes of the deplorable housing in New York’s East Side tenements, Richard Wright tells of life in South Side Chicago’s kitchenettes, and N. Scott Momaday depicts dark and cold apartments in Los Angeles as well as emptying homes on the reservation. What is shared by all three writers is their use of realism to depict abject housing, their clear engagement with public discourses about living spaces, and the way their works expose the production of space by social, economic, and legislative factors. All three published works that were widely received by the reading public and thereby contributed to the discourses in powerful and surprising ways. All three literary authors of this dissertation register a sense of space that is produced by power. Yezierska, Wright, and Momaday provide fictional, narrative modes of engagement that employ a particularly material-spatial register to depict spatial injustice. In order to read the production of space in these texts, I draw on the work of the theorists Henri Lefebvre, David Harvey, and Edward Soja to help explain the wider circumstances causing disenfranchisement, exploitation, and disempowerment that all three authors investigate. What is at stake here is a more complete picture of social crisis. By illustrating how bad housing is a result of political, economic, and social powers rather than the result of an individual’s laziness or lack of character, Yezierska, Wright, and Momaday add another perspective to prominent social discourses about housing in the twentieth century. The literary houses they depict uncover a history of systematic inequality in which prevalent national attitudes led to policy that put lower-classes and minority populations in bad housing and consequently foreclosed their potential to partake in the supposed full possibilities of citizenship. / 2020-11-07T00:00:00Z

In the early 1950s the study on how to determine true ore-grade distributions in the mining sector, sparked the development of a series of statistical tools that specifically allows for spatial and subsequently spatial-temporal dependence. These statistics are commonly referred to as geostatistics, and has since been incorporated in several fields of study characterized by this dependence. Basic descriptive statistics and mapping tools for geostatistics are defined and illustrated by means of a simulated dataset. The moments are modelled according to predefined conditions and model structures to describe the spatial and spatial-temporal variance in the data. These variograms and covariance structures are subsequently utilized in the least square procedure, namely kriging. At present, kriging is most commonly used in geostatistics for the interpolation and simulation of spatial or spatial-temporal data. The univariate and multivariate spatial and spatial-temporal kriging techniques are tested on the simulated dataset, to demonstrate how interpolation weights are determined according to the lag distances and underlying variance structure. The strength, weaknesses and inherent complexities of the methodologies are highlighted. / Dissertation (MSc)--University of Pretoria, 2010. / Statistics / unrestricted

Florida’s Voluntary Pre-Kindergarten program (VPK) aims to ensure that all 4-year-olds are prepared to excel in K-12 mathematics. Early numeracy/spatial skills are predictive of success in K–12 mathematics. No research has examined whether VPK classrooms are equipped with the materials necessary to teach numeracy/spatial skill. The Pre-Kindergarten Numeracy and Spatial Environment Survey was created to examine the frequency of access to and use of numeracy/spatial materials in VPK classrooms. The 69-item survey was completed by the lead educator from a sample of 62 pre-kindergarten classrooms in Miami-Dade County. Regression analysis results suggest the location of the pre-kindergarten center, the sex distribution of the children in the classrooms or the number of years of experience that the educator has as a lead teacher along with the extra training courses undertaken by the teachers does not affect the access to or the use of, numeracy and spatial materials in the classrooms.

Navigating to a previously seen target without vision was unaffected by a 30-sec delay period at the beginning of the walking task. This study investigated whether a 60-sec delay, with or without a cognitive task, would modify the accuracy of reaching an 8-meter target. Thirty young adults participated. The delay, located at 0, 4, or 7 meters, was either to wait, or to count backwards. Kinematic data of distance travelled, distance-to-target, angular deviation, and body rotation from participants’ final position were recorded with a 3-D motion analysis system. Navigation precision was not significantly different with or without a delay, and whether or not the delays contained a cognitive task. However, comparisons among delays revealed a significant effect of delay position with larger distance errors occurring at the 0-meter delay in the 16 participants who walked at least 7 meters, suggesting that a delay at the beginning was more disruptive for navigation accuracy than when it occurred closer to the target.

With the exponential growth of the usage of web-based map services, the web GIS application has become more and more popular. Spatial data index, search, analysis, visualization and the resource management of such services are becoming increasingly important to deliver user-desired Quality of Service. First, spatial indexing is typically time-consuming and is not available to end-users. To address this, we introduce TerraFly sksOpen, an open-sourced an Online Indexing and Querying System for Big Geospatial Data. Integrated with the TerraFly Geospatial database [1-9], sksOpen is an efficient indexing and query engine for processing Top-k Spatial Boolean Queries. Further, we provide ergonomic visualization of query results on interactive maps to facilitate the user’s data analysis. Second, due to the highly complex and dynamic nature of GIS systems, it is quite challenging for the end users to quickly understand and analyze the spatial data, and to efficiently share their own data and analysis results with others. Built on the TerraFly Geo spatial database, TerraFly GeoCloud is an extra layer running upon the TerraFly map and can efficiently support many different visualization functions and spatial data analysis models. Furthermore, users can create unique URLs to visualize and share the analysis results. TerraFly GeoCloud also enables the MapQL technology to customize map visualization using SQL-like statements [10]. Third, map systems often serve dynamic web workloads and involve multiple CPU and I/O intensive tiers, which make it challenging to meet the response time targets of map requests while using the resources efficiently. Virtualization facilitates the deployment of web map services and improves their resource utilization through encapsulation and consolidation. Autonomic resource management allows resources to be automatically provisioned to a map service and its internal tiers on demand. v-TerraFly are techniques to predict the demand of map workloads online and optimize resource allocations, considering both response time and data freshness as the QoS target. The proposed v-TerraFly system is prototyped on TerraFly, a production web map service, and evaluated using real TerraFly workloads. The results show that v-TerraFly can accurately predict the workload demands: 18.91% more accurate; and efficiently allocate resources to meet the QoS target: improves the QoS by 26.19% and saves resource usages by 20.83% compared to traditional peak load-based resource allocation.

We conducted three experiments to better understand how mothers structure their input to young children for finding hidden objects and how young children use this input to guide their searches. We examined the reference frames and spatial terms mothers use to communicate with their 2.5-, 3.0-, and 3.5-year-old children about location by asking mothers to verbally disambiguate a target hiding container from an identical non-target hiding container for their child. We varied the relative proximity of the target and non-target containers to a landmark and to the mother and child. The target and non-target containers were on opposite sides of the landmark in Experiment 1 and on the same side of the landmark in Experiments 2 and 3. The absolute distance of the containers from the landmark was increased in Experiment 3, while the relative distance of the containers to the landmark and to the mother and child remained the same. In all of the experiments, mothers' reference frame use was governed by the relative proximity of the target and non-target containers to the landmark and themselves. Older children followed directions more successfully than did younger children. The Discussion focuses on how the age of the child and the characteristics of the task shape maternal spatial communication.
