Spatial Analysis Of Housing Vacancy : Time Lag, Spillover Effects, And Spatial Heterogeneity, Yutian Feng
Spatial Analysis Of Housing Vacancy : Time Lag, Spillover Effects, And Spatial Heterogeneity, Yutian Feng
Legacy Theses & Dissertations (2009 - 2024)
The housing vacancy issue has long been a concern for community development and urban planning, especially in old industrial cities since the second half of the 20th century. Following the subprime lending crisis in 2007, the problem of housing vacancy again attracts attention as it causes problems like housing inequity, neighborhood redevelopment, and spatial justice in most U.S. cities. This dissertation systematically builds up an analytical framework to explore the mechanism of housing vacancy, using Buffalo urban area as a case study. Firstly, the research pays attention to the factors contributing to housing vacancy. The dissertation also investigates if there …
Addressing The Scale Issues In Spatial-Temporal Analysis Of Crime : An Integrative Framework And Empirical Findings, Mohammed Abdulrazak Alazawi
Addressing The Scale Issues In Spatial-Temporal Analysis Of Crime : An Integrative Framework And Empirical Findings, Mohammed Abdulrazak Alazawi
Legacy Theses & Dissertations (2009 - 2024)
Based on a critical review of existing literature in the spatial-temporal analysis of crime, three challenges have been identified: spatial-temporal scaling, theorizing spatial patterns for different types of crime, and the micro interaction between space and time. The spatial-temporal scaling issue is related to choosing the appropriate geographic unit of analysis. The theoretical issue concerns the lack of an integrative approach that can integrate the benefits of each theoretical perspective and identify broader processes to explain the resulting spatial patterns for different types of crime. Also, examining and explaining the variation of the micro space-time interactions for different types of …
Visual Variables On Mobile Devices : An Empirical Study Of Their Roles In Gaining Spatial Awareness, Andrew Donghyun Kim
Visual Variables On Mobile Devices : An Empirical Study Of Their Roles In Gaining Spatial Awareness, Andrew Donghyun Kim
Legacy Theses & Dissertations (2009 - 2024)
More people are used to and comfortable using mobile devices compared to traditional paper maps. Multiple studies have suggested that user's spatial awareness tends to decrease as the user passively follows directions on a mobile device with diminished screen size. One way to overcome the shortcoming of the small screen is through displaying discrete off-screen objects (landmarks) located beyond the extent of mobile map displays. The current study empirically examines the effectiveness of using visual variables including size, fuzziness, and transparency to embed distance and direction information in implicit icons of off-screen objects. This study investigates the effectiveness of these …
Supporting Spatial Orientation : Using Resizable Icons To Visualize Distant Landmarks On Mobile Phones, Jiayan Zhao
Supporting Spatial Orientation : Using Resizable Icons To Visualize Distant Landmarks On Mobile Phones, Jiayan Zhao
Legacy Theses & Dissertations (2009 - 2024)
Mobile phones have become so popular in navigation. Empirical studies, however, have implied several pitfalls of using these mobile systems. First of all, the small size of the mobile screen fragmentizes the map information so that users have to interact with the display frequently for fear of disorientation. In addition, generated navigation guides with continuous displays of routing information relieves users’ cognitive load, but the excessive reliance on the displayed spatial information keeps the users being mindless of the environment that impacts their acquisition of spatial knowledge. Later, landmarks as important referents were suggested to help users integrate the current …
Identifying Spatial Process Of Vacant Housing In Buffalo Core Urban Area, Yutian Feng
Identifying Spatial Process Of Vacant Housing In Buffalo Core Urban Area, Yutian Feng
Legacy Theses & Dissertations (2009 - 2024)
With the fact that vacant houses contribute to decline of living environment, understanding spatial distribution and agents of vacant house behind that spatial pattern is necessary for policy-makers to better work out proactive plans. An agreement that vacant buildings are not only symptomatic of other problems but even contributes to neighborhood decline. Thus, this paper will examine spatial characteristics of the compact and contiguous Buffalo urban district through three steps. First, we will test if there is spatial auto-correlation of vacant houses throughout the whole study area by global Moran’s I. Secondly, the Ordinary Least Square Regression Model without considering …
Using Storm-Watersheds And A Multi-Criteria Decision Model For Biodiversity Conservation In An Urban Environment, Christina M. Chiappetta
Using Storm-Watersheds And A Multi-Criteria Decision Model For Biodiversity Conservation In An Urban Environment, Christina M. Chiappetta
Legacy Theses & Dissertations (2009 - 2024)
Many planning and land use decisions in New York State are controlled at the local (town or municipal) level, not an optimal scale for planning and implementing resource conservation management. Watershed boundaries provide a more ecologically meaningful scale for conservation, because they capture a full range of natural ecosystem processes that span political boundaries. However, defining an urban watershed is complicated by stormwater infrastructure, so standard topographic watershed boundaries may be inadequate for urban resource conservation even when applied at the watershed scale. Storm-watersheds distort both municipal and watershed boundaries, because the flows are redirected in ways that are often …
Compression Of Gps Trajectory Data : Benchmarking Framework And New Approach, Jonathan Muckell
Compression Of Gps Trajectory Data : Benchmarking Framework And New Approach, Jonathan Muckell
Legacy Theses & Dissertations (2009 - 2024)
GPS-equipped mobile devices such as smart phones and in-car navigation units are collecting enormous amounts of spatial and temporal information that traces a moving object's path. The exponential increase in the amount of such trajectory data has caused three major problems. First, transmission of large amounts of data is expensive and time-consuming. Second, queries on large amounts of trajectory data require computationally expensive operations to extract useful patterns and information. Third, GPS trajectories often contain large amounts of redundant data that waste storage and cause increased disk I/O time. These issues can be addressed by algorithms that reduce the size …
A Study Of Habitat Selection By Blanding's Turtles (Emydoidea Blandingii) In Dutchess County, New York, Shannon Rauch
A Study Of Habitat Selection By Blanding's Turtles (Emydoidea Blandingii) In Dutchess County, New York, Shannon Rauch
Legacy Theses & Dissertations (2009 - 2024)
The Blanding's turtle (Emydoidea blandingii) is a New York State-listed threatened species with several disjunct populations located throughout the state. Blanding's turtles require a variety of habitat types including ponds, wetlands, vernal pools, and the surrounding uplands. Preserving these habitat complexes is necessary to ensure the persistence of Blanding's turtle populations, but this is becoming increasingly challenging in some locations due to significant development pressure. Key components of habitat protection are identifying preferred habitat types and gaining a better understanding of the variables that influence habitat selection. Previous landscape-level studies of turtles have found that land cover type, wetland type, …
Site Identification, Delineation, And Evaluation Through Quantitative Spatial Analysis : Geostatistical And Gis Methods To Facilitate Archaeological Resource Assessment, James Scott Cardinal
Site Identification, Delineation, And Evaluation Through Quantitative Spatial Analysis : Geostatistical And Gis Methods To Facilitate Archaeological Resource Assessment, James Scott Cardinal
Legacy Theses & Dissertations (2009 - 2024)
This thesis presents a brief overview of quantitative spatial analysis in archaeology with a discussion of the theoretical and methodological issues involved, and describes a set of methods for using Geographic Information System (GIS) software and spatial statistics for the assessment of archaeological resources. GIS has become a nearly ubiquitous and indispensable tool in many fields of resource management including archaeology. It is, however, applied by archaeologists most frequently for basic cartographic representations, large-scale regional analyses, or resource management data warehousing. Such applications underutilize the scale-independence of GIS, which is equally potent for intra-project data assessment. This thesis describes a …
