Title
MONITORING LONG-TERM CONTROLLED GRAVE SCENARIOS USING GROUND PENETRATING RADAR.
Creator
Hawkins, William, Schultz, John, University of Central Florida
Abstract / Description
Geophysical techniques, such as ground-penetrating radar (GPR), have been successfully used by law enforcement agencies to locate graves and forensic evidence. However, more controlled research is needed to better understand the potential and limitations of this technology in the forensic context. The goal of this study was to determine the potential of GPR using both a 250 MHz and 500 MHz antennae to monitor eight controlled graves with six different burial scenarios using pig carcasses as...
Show moreGeophysical techniques, such as ground-penetrating radar (GPR), have been successfully used by law enforcement agencies to locate graves and forensic evidence. However, more controlled research is needed to better understand the potential and limitations of this technology in the forensic context. The goal of this study was to determine the potential of GPR using both a 250 MHz and 500 MHz antennae to monitor eight controlled graves with six different burial scenarios using pig carcasses as human proxy cadavers. In addition, a conductivity meter was employed to determine the applicability of using this technology to locate unmarked graves. For the conductivity meter, the data was processed using an EM38 program in conjunction with the SURFER program to display a conductivity contour map of the grid. For the GPR imagery, reflection profile data was processed using the program REFLEXW while horizontal slices were processed using the GPR-SLICE program. Results indicate that the conductivity meter is not a viable option in the detection of clandestine graves when other geophysical tools are available. For the GPR, results indicate that while graves can still be detected after a two-year period, there is a marked decrease in the response, or resolution, of the burial scenarios. Furthermore, burials with grave goods interred along with the carcasses were far more likely to be detected than burials that were interred with no accompanying grave goods. When comparing the performance of the two antennae, the 250 MHz antenna provided increased resolution for large cadavers buried in deep graves.

Abstract / Description
This interdisciplinary dissertation explores perceptions of control in modded and unmodded versions of Bethesda's sandbox video game Skyrim. Sandbox games are known for greater choice options that suggest greater perceptions of control for gamers. Sandbox games also generally encourage the use of user-generated creations called modifications (mods) that users can download to personalize their games.

Show moreThis interdisciplinary dissertation explores perceptions of control in modded and unmodded versions of Bethesda's sandbox video game Skyrim. Sandbox games are known for greater choice options that suggest greater perceptions of control for gamers. Sandbox games also generally encourage the use of user-generated creations called modifications (mods) that users can download to personalize their games. While we need philosophy to understand and define control as a concept, we also need psychology to understand how users perceive control in media studies. At present, qualitative academic research that measures gamer perceptions of control is non-existent as is research on how users articulate their experiences with mods. Interviews were conducted with twenty-seven individuals who identified as gamers to analyze these perceptions of control in a game like Skyrim. The first chapter is introductory and outlines key terms for the dissertation as well as the play study's methodology. The second chapter examines philosophical and psychological perceptions of control that correspond with negative freedom (freedom from) and positive freedom (freedom to). While no game can promise radical free will because they have been programmed in advance, the information here may be used to demonstrate how perceptions of control might influence game design. The third chapter continues this exploration of perceived control through genre analysis, revealing the relationship between greater perceptions of control and mod support in sandbox video games. The fourth chapter presents the first two findings from the play study that demonstrate how mods influence player perceptions of control. The fifth chapter reveals how gamers of the play study discuss their perceptions of control video games in their own words with an emphasis on positive and negative freedom and generic conventions. The final chapter provides challenges for game design and scholarly qualitative analysis for future research based on findings in the play study.

Show moreSince the beginning of signalization of intersections, the management of traffic congestion is one of most critical challenges specifically for the city and urbanized area. Almost all the municipal agencies struggle to manage the perplexities associated with traffic congestion or signal control. The Adaptive Traffic Control System (ATCS), an advanced and major technological component of the Intelligent Transportation Systems (ITS) is considered the most dynamic and real-time traffic management technology and has potential to effectively manage rapidly varying traffic flow relative to the current state-of-the-art traffic management practices.InSync ATCS is deployed in multiple states throughout the US and expanding on a large scale. Although there had been several 'Measure of Effectiveness' studies performed previously, the performance of InSync is not unquestionable especially because the previous studies failed to subject for multiple environments, approaches, and variables. Most studies are accomplished through a single approach using simple/na(&)#239;ve before-after method without any control group/parameter. They also lacked ample statistical analysis, historical, maturation and regression artifacts. An attempt to evaluate the InSync ATCS in varying conditions through multiple approaches was undertaken for the SR-434 and Lake Underhill corridor in Orange County, Florida. A before-after study with an adjacent corridor as control group and volume as a control parameter has been performed where data of multiple variables were collected by three distinct procedures. The average/floating-car method was utilized as a rudimentary data collection process and 'BlueMac' and 'InSync' system database was considered as secondary data sources. Data collected for three times a day for weekdays and weekends before and after the InSync ATCS was deployed.Results show variation in both performance and scale. It proved ineffective in some of the cases, especially for the left turns, total intersection queue/delay and when the intersection volumes approach capacity. The results are verified through appropriate statistical analysis.

Show moreThe Multiple Streams model developed by John Kingdon (1995) and Nikolaos Zahariadis (2007) provides a valuable framework for understanding the nature of policy change. This investigation draws extensively upon the Multiple Streams framework in order to understand the development of gun-control policy initiatives under President Barack Obama.The investigation uses a case-study approach with in-depth analysis of four different mass-shooting events that took place in the United States between 2009 and 2012. Reconstruction of the shooting events and detailed parsing of the Obama administration's official responses to each incident, when viewed through the Multiple Streams lens, clearly explain why Obama's aggressive policy initiative was so delayed in its emergence in spite of several shootings and the President's clearly stated belief that gun-reform was a necessary step for the federal government. While the term (")policy change(") is broad and may encompass all sorts of governmental responsiveness, the term herein should be interpreted in the narrowest sense: exclusively encompassing legislative initiatives.Ultimately, the investigation concludes that numerous factors, but most prominently concerns about the timing and results of the 2010 Midterm and 2012 General Elections, prevented an aggressive pursuit of gun-reform prior to January 2013. The tragic shooting of 28 people in Newtown, Connecticut, then served as a prime focusing event for the President to aggressively engage a long-standing goal.
