Leadership Survival And The Process Of Economic Integration, Schuyler Richard Porche Jan 2009

Leadership Survival And The Process Of Economic Integration, Schuyler Richard Porche

LSU Doctoral Dissertations

The central contribution of this dissertation to political science is explaining the role of leadership survival theory in shaping the political process of initiation, broadening, deepening, and failure of economic integration agreements by nation states. The empirical research involves the creation of a dataset recording changes in economic integration for the period 1950-1999 and utilizing advanced quantitative methods to study the process. Most existing research focuses on the initiation of trade agreements. I demonstrate that the process of economic integration agreements among polities is shaped by iterated political interaction at both the domestic and international levels. The critical test in …

Essays On Management Quality, Ipo Characteristics And The Success Of Business Combinations, Haksoon Kim Jan 2009

Essays On Management Quality, Ipo Characteristics And The Success Of Business Combinations, Haksoon Kim

LSU Doctoral Dissertations

A Special Purpose Acquisition Company (SPAC) is a blank check company with no business operation but management quality. It raises money through unit IPO and put proceeds in a trust account for future business combination. In the post IPO market, the market price would reflect the value of trust account and management quality of profitably acquiring a firm with business operation. Thus, SPACs provide a unique setting to examine the pricing of management quality. Compared with regular IPO firms, SPAC management has more industry experience and the market put a higher value for SPACs with better management experience. SPACs with …

Beyond Crime Quantites: A Multilevel Analysis Of The Relative Prevalence Of Interracial Violence, Shaun A. Thomas Jan 2009

Beyond Crime Quantites: A Multilevel Analysis Of The Relative Prevalence Of Interracial Violence, Shaun A. Thomas

LSU Doctoral Dissertations

Prior research examining between community variations in violent crime has largely been guided by the social disorganization perspective and the systemic model of community attachment. This literature supports a strong relation between structural resource deprivation, residential instability, and rates of violent crime. In communities where poverty, unemployment, and broken families are geographically concentrated and home ownership and length of residence are relatively low, levels of violent crime are exacerbated. This dissertation extends prior research by focusing on variation in the nature or quality of violence rather than crime rates or quantities. While many analyses explore variations in rates of crime, …

Evidence That The Boundary Element-Associated Factors Beaf-32a And Beaf-32b Affect Chromatin Structure In Drosophila Melanogaster, Matthew Kenneth Gilbert Jan 2009

Evidence That The Boundary Element-Associated Factors Beaf-32a And Beaf-32b Affect Chromatin Structure In Drosophila Melanogaster, Matthew Kenneth Gilbert

LSU Doctoral Dissertations

The Boundary Element-Associated Factors, BEAF-32A and BEAF-32B bind to hundreds of loci on Drosophila chromosomes. These proteins function as insulators; they can prevent promoter activation by an enhancer when placed between them and protect transgenes from chromosomal position effects. To gain insight into BEAF function we designed and expressed a transgene encoding a dominant-negative form of BEAF. This peptide, BID, consists of the BEAF self-interaction domain. We demonstrate here that this peptide interferes with BEAF’s ability to bind DNA and prevents it from functioning as an insulator. In addition, expression of BID leads to a global disruption of polytene chromosome …
