With rapid advance of information technology (IT), computer-based gaming has flourished for decades. Gaming becomes a part of modern culture, especially among emerging digital generations. In addition to the entertaining purpose, attempts are made to use games for serious purpose, such as education and training. With the genuine characteristics that bring enjoyment, engagement, and context, games are considered good tools for business education and training that support or even may substitute the traditional learning methods. However, there is a dearth of research with regards to the comprehensive view of how people can learn business topics through serious games and transfer …
"Superbly Sterile:" Queer Reproduction In Victorian Literature And Culture, Mary Timothy Wilson
"Superbly Sterile:" Queer Reproduction In Victorian Literature And Culture, Mary Timothy Wilson
LSU Doctoral Dissertations
Examining a broad range of texts,“‘Superbly Sterile:’ Queer Reproduction in Victorian Literature and Culture,” argues that Thomas Hardy’s final naturalist novels, popular nineteenth-century vampire narratives, and the fiction of Oscar Wilde queered the bildungsroman (or novel of development) through characters who failed or refused to progress along sexual and maturational timelines. Where these texts’ critics have tended to read them as cautionary tales about homosexuality or predatory female sexuality, this dissertation contends that they also presented alternate forms of kinship and reproduction. They do so through the use of recursive, inverted, or otherwise backward relationships to time. Where Victorian sexology …
Scanning Probe Investigations Of Nanopatterned And Thermo-Responsive Polypeptoids And The Design Of A Sample Stage For Force Modulation Microscopy, Lu Lu
LSU Doctoral Dissertations
Protocols for patterning nanostructures of polymers were developed to enable scanning probe microscopy (SPM) studies of surface properties at the molecular level. A chemically selective surface for patterning polymers was generated by combining particle lithography with organosilane immersion. Poly(N-allyl glycine), a biocompatible and backbone degradable polypeptoid, was grown on Si(111) at confined amine sites using surface-initiated polymerization (also known as the “graft from” approach). A thermo-responsive random copolypeptoid, poly[(N-ethyl glycine)32-r-(N-butyl glycine17)], was pre-synthesized and attached onto a patterned organosilane surface using a thiol-ene click reaction (“graft to” approach). The phase transitions of the copolypeptoid nanostructures in an aqueous environment was …

A Quantitative Study Using Constructist Learning Activities To Connect Biology Concepts To Local Environmental Issues In A Non-Major Introductory College Biology Course, Michaelyn Broussard
LSU Doctoral Dissertations
Among the general population, there has continued to be a struggle to improve environmental literacy with the knowledge, attitude, and awareness of basic environmental issues locally and nationally. Despite efforts through many formal and informal programs, the result nationally has indicated little to no understanding of basic environmental issues (Coyle, 2005). Many educators such as Sobel (1996, 2004) and Louv (2005) have documented the lack of positive outdoor experiences or environmental behaviors. The purpose of this study was to incorporate local environmental examples through constructivist learning techniques within a general biology non-major course to promote an increase in environmental literacy …

Three Year Assessment Of Nearshore Crude Oil Contamination In The Gulf Of Mexico Using Gulf Menhaden (Brevoortia Patronus) As An Indicator Species: Menhaden Watch, Gregory Michael Olson
LSU Doctoral Dissertations
Approximately 4.9 million barrels of crude oil along with natural gas were released into the Gulf of Mexico (GoM) from April to July 2010 (Deepwater Horizon, DWH, spill). Impacts of this magnitude seldom occur in the GoM (Ixtoc I was the last spill close to this magnitude occurring in 1979), and one cannot predict when they will happen. Major constituents of concern found in crude oil are Polycyclic Aromatic Hydrocarbons (PAHs), which often have low volatility that allows for prolonged existence in the environment. PAHs are compounds of concern according to the United States Environmental Protection Agency (USEPA), with one …
Two Essays On Institutional Investors And U.S. Bank Holding Companies, Hui Wang
Two Essays On Institutional Investors And U.S. Bank Holding Companies, Hui Wang
LSU Doctoral Dissertations
This dissertation studies institutional investment in U.S. bank holding companies (BHCs). The first essay examines institutional investing preferences in U.S. banks and the impact of expansion of bank power on the preferences. Institutional investors prefer BHCs that hold more liquid assets, are better capitalized and larger in size, have better loan quality, lower stock return volatility and less derivative trading. In addition, the expansion of bank power is welcomed by various types of institutional investors, except for long-term institutions. Institutional investors also become less risk-averse when investing in BHCs that have expanded into non-banking business. However, the increased complexity and …
The Edible Landscape: Plant Breeding, Farming, And Sustainbility In Northwest Portugal, Joseph Blanchard Powell
The Edible Landscape: Plant Breeding, Farming, And Sustainbility In Northwest Portugal, Joseph Blanchard Powell
LSU Doctoral Dissertations
This dissertation is an ethnographic analysis of a participatory plant breeding project in northwest Portugal. Participatory plant breeding (PPB) is a crop enhancement strategy that brings farmers and plant breeders together in the effort to conserve crop genetic resources in-situ, improve yield, and increase the overall agricultural sustainability in agriculture. One strategy in PPB calls for plant breeders to spend considerable time on working farms to understand better farmers’ knowledge and skill, and to survey the existing crop genetic diversity within the existing resource limitations on farms. Although there are clear social implications for PPB, the bulk of PPB evaluative …
Essay On Anti-Takeover Provisions And Corporate Spin-Offs, Wei Du
Essay On Anti-Takeover Provisions And Corporate Spin-Offs, Wei Du
LSU Doctoral Dissertations
Despite the prevalent use of anti-takeover provisions (ATPs) based indices as measures of corporate governance quality, the role of ATPs (efficiency vs. entrenchment hypotheses), and their relationship to firm performance are not fully understood. Corporate spin-offs offer a unique opportunity to disentangle entrenchment motives from efficiency motives behind the adoption of ATPs. This setting also provides relatively clean inferences on the relation between ATPs and firm performance. This paper studies the design of ATPs in spun-off firms relative to their parents, the determinants of ATPs, and their relationship to subsequent firm performance. We show that spun-off firms typically are endowed …

On The Role Of Surface Roughness In Elastohydrodynamic Lubrication Of Tribological Components, Mohammad Masjedi
On The Role Of Surface Roughness In Elastohydrodynamic Lubrication Of Tribological Components, Mohammad Masjedi
LSU Doctoral Dissertations
The present dissertation investigates the effect of surface roughness in the elastohydrodynamic lubrication (EHL). Since many essential components of the machinery such as gears, rolling element bearings, cam-followers, and heavily loaded journal bearings operate under the mixed EHL condition, and given the fact that nearly all engineering surfaces are rough to some extent, there is a need for an extensive research which can realistically quantify the effect of the surface roughness in such applications. We thus seek to develop an applied engineering approach for the treatment of the mixed EHL for prediction of the performance of machinery. Both line-contact and …
