Time-Series Analysis Of Clusters In City Size Distributions, Ahjond S. Garmestani, Craig R. Allen, K. Michael Bessey

Complex systems, such as urban systems, emerge unpredictably without the influence of central control as a result of adaptive behavior by their component, interacting agents. This paper analyses city size distributions, by decade, from the south-western region of the United States for the years 1890–1990. It determines if the distributions were clustered and documents changes in the pattern of clusters over time. Clusters were determined utilizing a kernel density estimator and cluster analysis. The data were clustered as determined by both methods. The analyses identified 4–7 clusters of cities in each of the decades analysed. Cities cluster into size classes, …

Citizen Based Public Health Surveillance, Monitoring And Post-Event Assessments, Thomas Lyons Carr Iii
Thomas Lyons (Thom) Carr III Appl.Sc., CEM
When a sudden on-set emergency or disaster affects a region or the whole country, communities and neighborhoods should plan for the possibility that emergency and other civic services will be disrupted and unavailable (District of Columbia 2003a, 2003b, 2004; Doyle 2004; Siskiyou County Public Health/NorCalBT.com 2004). The event may be severe enough that the routine public health surveillance and monitoring system will be disrupted or the system will not be able to provide data quickly enough to support state and local decisionmaking. A temporary post-disaster system should be planned for and implemented. The epidemiologist supporting the local decision makers must …
The Segregated Distribution Of Middle Class African American Households In The Pittsburgh Metropolitan Statistical Area, Jay L. Newberry
The Segregated Distribution Of Middle Class African American Households In The Pittsburgh Metropolitan Statistical Area, Jay L. Newberry
Theses, Dissertations and Capstones
This research analyzes the residential distribution of middle-class African American households in the Pittsburgh Metropolitan Area to determine if the "middle class" status affords them greater integration with the dominant white group. Using 1990 and 2000 census income data for white and black households in the Pittsburgh MSA, lower, middle, and upper class categories were created in both groups for comparison against the black middle class category via five segregation indices. This research found that, although the African American households experience varying degrees of segregation by class, all are highly segregated from the white group with middle class African American …
Extending Spatial Hot Spot Detection Techniques To Temporal Dimensions, Sungsoon Hwang
Extending Spatial Hot Spot Detection Techniques To Temporal Dimensions, Sungsoon Hwang

This paper presents how hot spot detection methods can be extended to allow for temporal dimensions. Major concerns are how temporal dimension is incorporated into the framework of point pattern analysis, while maintaining the capability of multi-scale analysis. The study elaborates on expanding the scope of (space) K function in order to count time in the analysis. With the explicit treatment of time as well as space, K function falls into three category depending on the way space and time are controlled; (1) space K function, (2) time K function, (3) space-time K function. Space K function is equivalent to …

The Atlas and Database of Air Medical Services (ADAMS) is a web-based, password-protected, geographic information system containing data on air medical service main and satellite base helipads, communication centers, rotorwing aircraft, and major receiving hospitals for trauma in the United States. ADAMS initially was developed to provide the geographic information needed to support realtime, wireless routing of automatic crash notification (ACN) alerts from a crashed motor vehicle to the nearest air medical transport service and trauma center. This coupling of ADAMS and ACN technology to enhance emergency communications is expected to speed delivery of emergency medical care to crash victims …
