The Design & Implementation of an Abstract Semantic Graph for Statement-Level Dynamic Analysis of C++ Applications
In this thesis, we describe our system, Hylian, for statement-level analysis, both static and dynamic, of a C++ application. We begin by extending the GNU gcc parser to generate parse trees in XML format for each of the compilation units in a C++ application. We then provide verification that the generated parse trees are structurally equivalent to the code in the original C++ application. We use the generated parse trees, together with an augmented version of the gcc test suite, to recover a grammar for the C++ dialect that we parse. We use the recovered grammar to generate a schema for further verification of the parse trees and evaluate the coverage provided by our C++ test suite. We then extend the parse tree, for each compilation unit, with semantic information to form an abstract semantic graph, ASG, and then link the ASGs for all of the compilation units into a unified ASG for the entire application under study. In addition, to relieve the cognitive burden of information that may inundate a developer, we describe our development of extensions to Hylian to build abbreviated abstract semantic graphs, which incorporate information about user code, but not about compiler provided library code. Finally, we describe the various approaches that we adopted to provide assurance for the developer that the ASGs that Hylian builds, correctly represent the program under study

The extent and impact of trust ownership on the sustainability and resiliency of Iowa’s agricultural landscape
The popularity of trusts as a land management tactic has been increasing. Using survey results, an attorney and economics professor examined the kinds of trust arrangements that exist in Iowa and how they might be used to encourage conservation practices and sustainable agricultural management
EFFECTS OF ALTERNATIVE FARM PROGRAMS AND LEVELS OF PRICE VARIABILITY ON TEXAS COTTON FARMS
This study examines the effects of alternative government farm programs and hypothetical price variability levels on two Texas cotton farms which were simulated stochastically over a 10-year period. Results indicate that a combination of high price variability and participation in government programs stimulates growth and wealth accumulation.Public Economics,
The Ethical Relationship Between School Violence and Teacher Morale
This study explores how negative school climate factors, such as classroom violence, can influence a teacher’s pedagogical approach to classroom learning and relationships with students using a transformative lens to improve student engagement and pedagogical approaches after such tragedies occur. The Burke-Litwin (2010) model of organizational climate is used as a framework to understand how a school\u27s organizational climate contributes to a positive learning culture for teachers, post-trauma, with the goal of heightening teachers’ ability to continue to teach and to maintain student engagement post-violence. Major conclusions show that the underlying school climate plays a critical role in how a teacher recovers after witnessing a school shooting. In the recovery of post-violent school events, school cultures have a major impact on teacher morale, relationships between teachers and students, absenteeism (student and teacher), school discipline and, grades and test scores. A school’s organizational climate essentially contributes to teachers’ abilities to engage students actively in the classroom and to continue to be involved in motivational teaching and new pedagogical approaches despite witnessing violence
Self-reliance: ethnography of literature outside Viet Nam
Self-Reliance: Ethnography of Literature Outside Viet Nam calls for literary activity that recognizes the emergence of the nation of Viet Nam in the modern world order. First, an introduction summarizes the work. Then, the first chapter introduces the figure of Nhat Linh, a founder of modern literature in Viet Nam during the colonial period, who as the nationalist revolutionary Nguyen Tuong Tam later committed suicide in dissent to the Saigon government of Ngo Dinh Diem. The second chapter introduces the broad sweep of Vietnamese history since the founding of the Nguyen dynasty in 1801, in terms of what can be seen walking the streets of Paris visiting Vietnamese bookstores. The third chapter concludes the dissertation by returning to the figure of Nhat Linh and discussing what the author of the dissertation is doing with Vietnamese literature in Orange County, North Carolina
Teaching HDFS/MapReduce Systems Concepts to Undergraduates
This paper presents the development of a Hadoop MapReduce module that has been taught in a course in distributed computing to upper undergraduate computer science students at Clemson University. The paper describes our teaching experiences and the feedback from the students over several semesters that have helped to shape the course. We provide suggested best practices for lecture materials, the computing platform, and the teaching methods. In addition, the computing platform and teaching methods can be extended to accommodate emerging technologies and modules for related courses
