Power Transition Theory And The Determinants Of Regional Integration Agreement Accession And Exit, James Langford

Open Access Theses & Dissertations

While the phenomenon of regional integration has been paid substantial attention, the question of what causes states to accede to or exit from regional integration agreements (RIAs) has not. I draw from power transition theory to explain membership in RIAs, hypothesizing that states accede to an RIA when there is a high level of both power preponderance and status quo satisfaction, and exit when the levels of those variables are both low. I employ large-N quantitive analysis to test my two hypotheses. I find weak support for the hypothesis on RIA exit and offer concluding remarks on what the results …

Thermal Behavior Of Plain And Fiber-Reinforced Rigid Concrete Airfield Runways, Arash Karimi Pour

Open Access Theses & Dissertations

The environmental condition and temperature gradient are important factors resulting in concrete airfield runways cracking during the time. Rigid concrete airfield runways experience different thermal gradients during the day and night due to changes in air temperature. Curling and thermal expansion stresses are the main consequences resulting in various types of cracking over the surface and thickness of concrete airfield runways and increasing maintenance costs. The curvature of concrete slabs increases with an increase in the temperature gradient which is amplified when runways open to traffic. Additionally, the combination of the curling and shrinkage stresses, in rare circumstances, can be …

Meaningfulness, Existentialism, And The Reverse Priority View, Aimee Adriana Santillan

Open Access Theses & Dissertations

In this thesis, I will argue that existentialism provides a more helpful guideline to understanding the relationship between meaningfulness and morality. Then, I will explain how existentialist ethics provides a good example of a moral theory that balances morality and meaningfulness. In Chapter 1, I will highlight the important considerations that philosophers like Susan Wolf, Bernard Williams, Harry Frankfurt, and Sophie Grace Chappell have pointed out could be reasons for action that are important enough to outweigh moral duty in some situations. In Chapter 2, I will further outline Wolfâ??s criticism of normative ethical theories and explain her â??meaningfulnessâ?? objection. …

A Mixed Method Approach To Explore Lecturers' Pedagogical And Content Knowledge, Students' Perspectives And Learning Experiences In Mathematics For Social Science Course, Julio Hector Solis
