Social Ape, Morgan Dione Harris Jan 2006

Social Ape, Morgan Dione Harris

LSU Master's Theses

“Social Ape” is an investigation and rationalization of America’s obsession with consumption. As a designer, this battle between consumption and individualistic expression has been intriguing. It is a platform for questioning how the public processes information supplied by marketing and advertising, resulting visually in interpretations of this information. It seems fascinating that even though consumers are constantly bombarded by persuasive propaganda, they feel in control of their purchasing decisions. To this end, I am using fashion as a tool for investigation. Fashion is a powerful commodity, representing identity and status, and thus fueling consumption and expression.

Applying Appraisal Theories Of Emotion To The Concept Of Emotional Labor, Erin Michele Richard Jan 2006

Applying Appraisal Theories Of Emotion To The Concept Of Emotional Labor, Erin Michele Richard

LSU Doctoral Dissertations

Interest in the role of emotions in the workplace has increased in recent years (e.g., Arvey, Renz, & Watson, 1998; Ashkanasy, Hartel, & Daus, 2002; Fisher & Ashkanasy, 2000; Muchinsky, 2000). One particular area of workplace emotions research deals with emotional labor, or the regulation of emotions as part of the work role (Hochschild, 1983). Although emotional labor research has examined the ways that individuals can regulate their emotions, this research typically is not grounded in theories of the emotion generation process (Ashton-James and Ashkanasy, 2004) and does not examine the causal effects of emotion regulation strategies on outcomes. The …

Essays On Group Lending: Evidence From Jordan, Moh'd Al-Azzam Jan 2006

Essays On Group Lending: Evidence From Jordan, Moh'd Al-Azzam

LSU Doctoral Dissertations

Group lending has received a great attention from economists and policymakers for its successful delivery of credit to poor borrowers and its role in alleviating poverty in the developing countries. The success of group lending in providing credit to poor borrowers has been attributed to its ability to mitigate the asymmetry of information and enforcement problems in credit markets. The ability of group lending institutions to overcome the asymmetry of information and enforcement problems has been theorized to be the driving force behind their outreach to the poor, their sustainability, and their repayment performance. While there is a host of …

Retention And Transport Of Arsenic In Soils, Hua Zhang Jan 2006

Retention And Transport Of Arsenic In Soils, Hua Zhang

LSU Doctoral Dissertations

Arsenic transport in soils and aquifers is highly dependent on the adsorption-desorption reactions in the solid phase. Results from our kinetic batch experiments indicated that adsorption of arsenate [As(V)] was highly nonlinear and strongly kinetic. Desorption of As(V) were hysteretic in nature and a significant amount of As(V) was irreversibly adsorbed on all soils. Results from column experiments indicated strong As(V) retardation followed by slow release or extensive tailing of the breakthrough curves (BTCs). Sharp decrease in As(V) concentration during flow interruption verified the extensive non-equilibrium condition which was likely due to the dominance of kinetic retention processes. We evaluated …
