This dissertation offers three independent studies that each contributes to the literature on trade facilitation. The papers are built on the gravity model framework where the relationship between trade facilitation variables and the volume of agricultural exports across the border are examined. To deal with the issue of endogeneity, instrumental variable regression is ....

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 fou....

A survey was conducted to document the silicon (Si) content of soils from 27 (selected) agrarian parishes of Louisiana using different extraction procedures. For 0.01 M calcium chloride (CaCl©ü) extraction procedure, all surveyed soils (n=212) fell below 56 mg Si kg⁻©ö. For five of the procedures, about 50% of surveyed soils in Louisiana had Si level below the cri....

This study explores the lived experiences of graduate assistants pursuing a masters degree in higher education. Graduate assistants now comprise approximately 12% of all postgraduate students in higher education. Thus, this qualitative study seeks to understand graduate assistants experiences and support them in honing the quality of their interactions and communication....

The Mexican rice borer, Eoreuma loftini (Dyar) (Lepidoptera: Crambidae) is an invasive stem borer pest of sugarcane, rice, corn, and sorghum, and poses a threat to the production of dedicated bioenergy feedstocks in the U. S. Gulf Coast region. Studies were conducted to assess insect-plant interactions between E. loftini and bioenergy and conventional cultivars of suga....

More complex image understanding algorithms are increasingly practical in a host of emerging applications. Object tracking has value in surveillance and data farming; and object recognition has applications in surveillance, data management, and industrial automation. In this work we introduce an object recognition application in automated nutritional intake analysis and....

When using a bidimensional mental health (BDMH) model, psychological distress and wellbeing are measured. This study used a mental health screening measure, with equal number of items measuring each mental health dimension (i.e., wellbeing and distress) to classify students into one of four possible mental health groups: mentally healthy (MH), mentally unhealthy (MU), s....

The Deep Water Horizon oilrig explosion led to the release of 6.8 ± 1.7 x 108 kg or 4.9 million barrels of petroleum hydrocarbons into the Gulf of Mexico. The spill persisted from the end of April to mid July 2010 affecting a significant portion of the Gulf coast. The effects of this spill are being studied in labs across the country, and this thesis investigated high-....

This thesis deals with understanding quantum gravitational effects in those anisotropic spacetimes which serve as black hole interiors. Two types of spacetime are investigated. Kantowski-Sachs spacetime and Bianchi-III LRS spacetime. The former, in vacuum, is the interor spacetime for Schwarzschild black holes. The latter is the interior for higher genus black holes. Th....

Writers have long explored and attempted to portray the visual artists challenge of creating the ideal in the real world through art. My thesis asserts that the Pygmalion myth, originally told in written form in Ovids 8 A.D. Metamorphoses, is the quintessential model to explore the changing, and sometimes problematic, relationships between the artist, the creation, and ....

RNA polymerase III (Pol III) transcribes tRNAs as well as other small non-coding RNAs. tRNA genes contain internal promoter sequences (A- and B-boxes) which can be specifically recognized and bound by TFIIIC. Binding of TFIIIC facilitates TFIIIB recruitment, which in turn targets Pol III to be recruited and initiate transcription. In addition to typical tRNA genes, ther....
