Analysis Of The Impact Of Fish Imports On Domestic Crawfish Prices And Economic Welfare Using Inverse Demand Systems, Young-Jae Lee
Analysis Of The Impact Of Fish Imports On Domestic Crawfish Prices And Economic Welfare Using Inverse Demand Systems, Young-Jae Lee
LSU Doctoral Dissertations
This study is mainly intended to determine quantitatively the economic effects of crawfish imports on the domestic crawfish industry. Inverse demand systems are used to estimate the price and scale flexibility as an indicator for the effects of imports on crawfish domestic price. A variety of algebraic forms for empirical consumer allocation models have been developed. Economic theory, however, does not provide the necessary fundamental criteria to choose ex ante among the alternative specifications. Bartern (1993) and Brown, Lee, and Seale (1995) examined a family of inverse demand systems, showing that the integrated demand system, in its own right, has …
Mechanism Of Intraspecific Toxin Inhibition In Aspergillus Flavus, Changwei Huang
Mechanism Of Intraspecific Toxin Inhibition In Aspergillus Flavus, Changwei Huang
LSU Master's Theses
Atoxigenic Aspergillus flavus was demonstrated by others as a promising biocontrol agent to minimize preharvest aflatoxins in susceptible crops. But the mechanism was unclear. A filter insert-well plate system was used to study the mechanism in lab. There was no inhibition when toxigenic A. flavus isolate 53 and inhibitory atoxigenic isolates were separated by 0.4 µm membrane, approximately 50% inhibition occurred when separated by 12 µm membrane, and complete inhibition occurred when a 74 µm membrane was used. This result suggested that touching or close physical interaction is needed for toxin inhibition and the nutrient competition hypothesis was not supported. …
Analysis Of Trade On El Salvador Post Dollarization, Jorge Raul Rivera
Analysis Of Trade On El Salvador Post Dollarization, Jorge Raul Rivera
LSU Master's Theses
Dollarization has been suggested as an option for emerging economies. This policy might, among other goals, promote trade between a country adopting the dollar and the United States. Recent research suggests that adopting a common currency increases bilateral trade. Those findings have been widely critiqued for the lack of consistency over different currencies specially the case of dollarization. This thesis is primarily concerned with the impact of dollarization in El Salvador regarding bilateral trade flows. Utilizing the framework of the Gravity Model, bilateral trade flows for 13 trading partners of El Salvador were examined. This study found that dollarization has …
An Analysis Of The Processor Preferences For The Adoption Of Potential Crawfish Peeling Machines, Darius J. Lewis
An Analysis Of The Processor Preferences For The Adoption Of Potential Crawfish Peeling Machines, Darius J. Lewis
LSU Master's Theses
Over the past decade, the peeling segment of the Louisiana crawfish industry has faced the challenge of remaining competitive in an increasingly global market. Since the mid-1990’s, there has been escalated discussion among Louisiana crawfish processors on the need for a crawfish peeling machine. The International Trade Commission determined that the U.S. crawfish industry had been “materially injured” by the imported tailmeat and ruled China was, in fact, dumping crawfish in the U.S. by selling below fair market value in the host country. The development of a suitable crawfish peeling machine could potentially increase production and lower cost of production, …
Chromosomal Stability And Epigenetic Modifications Of Fibroblast Cells Used For Nuclear Transfer, Angelica Maria Giraldo Gomez
Chromosomal Stability And Epigenetic Modifications Of Fibroblast Cells Used For Nuclear Transfer, Angelica Maria Giraldo Gomez
LSU Doctoral Dissertations
Investigations into the importance of the nuclear integrity of the donor cell prior to nuclear transfer (NT) are limited. In Experiment 1, the proliferative characteristics, chromosomal stability and level of histone phosphorylation in cell lines established by explants and enzymatic dissociation at different population doublings (PDs) were investigated. The cells divided at a constant rate and cell cycle length increased only at the end of the proliferative stage. The level of aneuploidies was high and remained elevated throughout the study independent of the technique used to establish the primary culture. High levels of multinucleated cells and abnormal spindle configurations were …
Intracellular Lipids In Bos Indicus And Box Taurus Oocytes, Casey Bryant Ballard
Intracellular Lipids In Bos Indicus And Box Taurus Oocytes, Casey Bryant Ballard
LSU Master's Theses
It has been proposed that Bos indicus when compared with Bos taurus embryos are more sensitive to cryopreservation procedures due to higher intracellular lipid content of the embryos. With cyropreservation of Bos indicus embryos increasing for export, it is essential to improve the viability of these cryopreserved embryos. In Experiment I, M-II oocytes from mice, pigs and cows were subjected to two different procedures to evaluate lipid content. The lipid content present in pig oocytes was significantly (P<0.05) higher when compared with mouse and cow oocytes. Pig oocytes had a lower settling point in the sucrose buoyant density gradient and higher Nile Red units, which indicated higher lipids present in the oocytes. In Experiment II, it was determined that M-II oocytes aspirated from superstimulated Brahman donors were significantly higher (P<0.05) in lipid content compared with English breed donors. The lipid content present in Brahman oocytes was higher when compared with English breeds when tested with a sucrose buoyant density gradient and Nile Red staining. In addition, donor females with higher body condition scores were significantly (P<0.05) higher in oocyte lipid content when compared with donor females of lower body condition scores. Furthermore, animal body condition scores, cholesterol and triglyceride levels prior to oocyte aspiration may be indicators of intracellular lipids in the oocytes and embryos. To our knowledge, this is the first report that evaluated intracellular lipid content of M-II oocytes of different beef breed types using a sucrose buoyant density gradient and Nile Red staining.
Record-Keeping Systems Adoption By Louisiana Dairy Farmers, Elisabeth Grisham
Record-Keeping Systems Adoption By Louisiana Dairy Farmers, Elisabeth Grisham
LSU Master's Theses
Fifty Louisiana dairy farmers were interviewed to gather production amounts, costs of production, management techniques, technologies adopted, and demographic information. These data were used to analyze what record-keeping systems the farmers were adopting and to what extent the systems were being used. Logit, ordered probit, negative binomial regression, OLS regression, and double hurdle models were used to determine adoption and intensity. In this study, age was found to decrease the probability that a farmer would believe their computer was not at all useful and also of limited usefulness, while increasing the probability that a farmer would believe the computer was …
Modeling The Eu-Us Cereal Trade - The Post 'Agenda 2000' Analysis, Sachin Chintawar
Modeling The Eu-Us Cereal Trade - The Post 'Agenda 2000' Analysis, Sachin Chintawar
LSU Master's Theses
Significant changes in attitudes toward farm policy and trade have occurred within the European Union and the United States in the past decade. Trade negotiations under the General Agreement on Tariff and Trade (GATT) specifically the Agreement on Agriculture (AoA) and later under the Doha Round of the World Trade Organization (WTO) have bought about considerable changes in the market structure in the cereals trade. Bilateral trade has further been impacted by the cessation of concession treaties like the Blair House Accord that expired at the end of the 2004 marketing year (WTO). Domestic budget pressures in the United States …
Drivers Of Liking And Effects Of Corn Hybrics On Quality Of Corn Tortilla, Jose Andres Herrera Corredor
Drivers Of Liking And Effects Of Corn Hybrics On Quality Of Corn Tortilla, Jose Andres Herrera Corredor
LSU Doctoral Dissertations
Corn tortilla, an ancient staple food of Mexico and Central America, is still the base food in those countries and has also become more popular in other countries with high Hispanic population. However, mechanization of corn tortilla production has modified the original sensory attributes to new standards that meet manufacturer’s requirements. The first part of this study attempted to determine the sensory attributes that drive consumer’s decision on the acceptability and purchase intent of the corn tortilla available in the Mexican market. The findings may help manufacturers to improve the processing of tortilla and develop products with ethnic authenticity. Overall …
Population Ecology Of Pseudacteon Tricuspis Borgmeier (Diptera: Phoridae), An Introduced Parasitoid Of The Red Imported Fire Ant Solenopsis Invicta Buren (Hymenoptera: Formicidae) In Louisiana, Donald Charles Henne
Population Ecology Of Pseudacteon Tricuspis Borgmeier (Diptera: Phoridae), An Introduced Parasitoid Of The Red Imported Fire Ant Solenopsis Invicta Buren (Hymenoptera: Formicidae) In Louisiana, Donald Charles Henne
LSU Doctoral Dissertations
Aspects of the population ecology of a parasitoid (Pseudacteon tricuspis) of the red imported fire ant (Solenopsis invicta) in Louisiana were studied. The spatio-temporal abundance patterns, dispersal, population spread, aggregation, direct mutual interference and functional response characteristics of this parasitoid were studied to address deficiencies in our knowledge about phorid flies, particularly Pseudacteon parasitoids. This endoparasitoid was discovered to manipulate host ant behavior in ways that benefit its own survival. Laboratory experiments to gain insights into behavioral and functional responses revealed that fly aggregations were density-dependent and interference was not significant when 1-3 females were simultaneously confined with hosts, although …
Vascular Function, Physical Performance And Aging, Devon Dobrosielski
Vascular Function, Physical Performance And Aging, Devon Dobrosielski
LSU Doctoral Dissertations
This is a series of three experiments with brachial artery flow-mediated dilation (BAFMD) as the major outcome variable. The first study examined the temporal response of the brachial artery diameter following forearm occlusion in sixteen young (28±8 years) and fifteen older (85±8 years) men. Following release of the pressure cuff there is a significant reduction in brachial diameter compared to baseline, followed by a rapid increase to a PEAK. When comparing the magnitude of the decrease in diameter and the BAFMD between Young and Old, older subjects demonstrated a blunted response. A significant relation was noted between the magnitude of …
Psychological Correlates Of Exercise Behavior Among Adolescents, Kevin C. Paul
Psychological Correlates Of Exercise Behavior Among Adolescents, Kevin C. Paul
LSU Master's Theses
According to the 2003 Youth Risk Behavior Surveillance Survey, 33% of youth in grades 9-12 participated in an insufficient amount of vigorous and moderate physical activity (PA), and 11% reported no vigorous and moderate PA. Although researchers have examined the psychological correlates of exercise behavior among youth, limited research investigating moderators of the theories of reasoned action (TRA; Ajzen & Fishbein, 1980) and planned behavior (TPB; Ajzen, 1985) in this population exists. Therefore, the main purpose of this study was to examine socioeconomic status (SES) as a moderator of the psychological correlates of exercise intention and behavior using the TRA/TPB …
Liability, Institutions, And Determinants Of Landowner Access Policies For Fee-Based Recreation On Private Lands, James Emery Henderson
Liability, Institutions, And Determinants Of Landowner Access Policies For Fee-Based Recreation On Private Lands, James Emery Henderson
LSU Doctoral Dissertations
Landowners in the Lower Mississippi Valley or Delta may be willing to consider alternative land uses for some acreage, particularly for marginal agricultural lands. Recreational hunting, fishing, and wildlife watching opportunities on private land for public use may be a possible way to provide income to landowners and restore marginal lands as a contributor to the local economy. Previous studies have identified that landowners often chose not to engage in recreational leasing due to liability concerns. Thus, an institutional change that reduces liability risk to landowners may increase the amount of private land available for public recreation and reduce transaction …
Cryopreservation Of White-Tail Deer Epididymal Sperm For Artificial Insemination, Jesse Ray Saenz
Cryopreservation Of White-Tail Deer Epididymal Sperm For Artificial Insemination, Jesse Ray Saenz
LSU Master's Theses
The ability to cryopreserve epididymal sperm from mature postmortem bucks has long been of interest to both wildlife conservationists and deer ranchers. Increased understanding of the cryobiology of epididymal sperm from a non domestic species, such as White-tail deer, could aid in development of future protocols to assist in the preservation of endangered species. In Experiment I, results showed that after cooling postmortem bull testes for 22 hours, no significant difference was noted between sperm parameters of epididymal sperm collected at room temperature or at a cool enviorment. In Experiment II, it was shown that White-tail deer sperm could be …

LSU Doctoral Dissertations
The general objective of this dissertation was to investigate physical function in osteoarthritis (OA) and total knee replacement (TKA) patients. First, a validation study was performed to evaluate the validity of the Continuous Scale Physical Functional Performance (CS-PFP10) test in knee OA awaiting TKA. The CS-PFP10 scores were compared to the Western Ontario and McMaster Universities OA Index (WOMAC), The Knee Society’s Clinical Rating System (KSS), and the Short Form 36-item health survey (SF-36) physical function scores. It was hypothesized that at least moderate associations between the CS-PFP10 test scores and the WOMAC, KSS, and SF-36 scores in TKA candidates …
Predictors Of Adl Disability In Culturally Diverse Older Adults, Fernanda Holton
Predictors Of Adl Disability In Culturally Diverse Older Adults, Fernanda Holton
LSU Master's Theses
Almost 42% of adults over 65 years of age live with at least one disability. Further, people of lower socioeconomic status and Blacks have greater risks for disability than Whites and individuals at higher socioeconomic status. The consequences of disability include loss of independence, decreased quality of life, increased chances of depression, consumption of health care services, and institutionalization. The purpose of this study was to utilize the disablement process framework to examine the contribution of physical function, dyspnea, and pain to disability in activities-of-daily-living (ADL) in culturally diverse older adults (i.e., diverse according to race, income, and education). Participants …

The temperatures 150oC and 175oC were used for the oxidation study and a 60oC was used for incubation storage. The methanol extracts of all four spices demonstrated significant capability in retaining the DHA and EPA, after subjected to oxidation when compared …
Understanding Students' Motivation In Physical Education: Integration Of Expectancy-Value Model And Self-Efficacy Theory, Zan Gao
LSU Doctoral Dissertations
The purpose of this dissertation was to integrate the expectancy-value model of achievement choice and self-efficacy theory among middle school students, with the goal of better understanding students’ motivational beliefs and the factors that influence these beliefs. Three quantitative studies were conducted to address this purpose. In study 1, the expectancy-value model constructs (expectancy-related beliefs and subjective task values) and self-efficacy theory constructs (self-efficacy and outcome expectancy) were measured in a sample of 225 students and were used to predict students’ in-class activity levels during a 2-week follow-up. Results of path analyses yielded that the hypothesized model fit the data …
Chemical Ecology, Fungal Interactions And Forest Stand Correlations Of The Exotic Asian Ambrosia Beetle, Xylosandrus Crassiusculus (Motschulsky) (Curculionidae), Eric Paul Ott
LSU Master's Theses
Increasing evidence of non-indigenous ambrosia beetles aggressively attacking hosts in their new environment in the United States has led to concern over the potential for damage to urban trees, nurseries, orchards, and forests. A novel technique of flooding host trees was devised to stimulate ambrosia beetle attacks, with ambrosia beetle attraction peaking four days following flooding. In-situ sampling identified significant differences in the composition, quantity and point of release (leaf or bole) of volatiles emitted by the flooded and non-flooded trees. Coupled gas chromatography electroantennographic detection revealed olfactory sensitivity by the ambrosia beetle Xylosandrus crassiusculus (Motschulsky) to 29 of these …
An Assessment Of The Risk Mapping System For The Use Of Managing Loblolly Pine Decline Sites Within Red-Cockaded Woodpecker Habitat, Roger Dale Menard
An Assessment Of The Risk Mapping System For The Use Of Managing Loblolly Pine Decline Sites Within Red-Cockaded Woodpecker Habitat, Roger Dale Menard
LSU Master's Theses
A decline of loblolly pine (Pinus taeda L.), characterized by expanding areas of declining and dead trees, has become prevalent at Fort Benning, Georgia. A 3 year study was conducted to determine the kinds of fungi, insects, and site disturbances associated with this problem. The insects Dendroctonus terebrans, Hylastes salebrosus, Hylastes tenuis, Pachylobius picivorus and Hylobius pales were significantly more abundant in symptomatic than in asymptomatic loblolly pine plots. These root and lower stem-infesting insects consistently carried the fungi Leptographium terebrantis, L. procerum, and L. serpens. Root sampling revealed high levels of root damage and mortality, staining and infection with …
Self-Control Of Learning Multiple Motor Skills, Wilbur Fong Wah Wu
Self-Control Of Learning Multiple Motor Skills, Wilbur Fong Wah Wu
LSU Doctoral Dissertations
Learning is commonly referred to as a “two-way street” between the learner and instructor. Until recently, learning has been studied using a “one-way” approach in which numerous studies have explored learning in situations where the experimenter or instructor shapes the practice environment. A number motor learning studies have shown the effectiveness of the learners’ abilities to control various aspects within their learning environment. Studies on augmented feedback (Chiviacowsky & Wulf, 2002; Janelle, Kim, & Singer, 1995), observational learning (Wulf, Raupach, & Pfeiffer, 2005), and physical assistance devices (Wulf & Toole, 1999) have found that learning is enhanced when individuals are …
Detection Of Vibrio Vulnificus By Direct Colony Immunoblot, Reshani Nisansala Senevirathne
Detection Of Vibrio Vulnificus By Direct Colony Immunoblot, Reshani Nisansala Senevirathne
LSU Master's Theses
Vibrio vulnificus (Vv) is a natural occurring bacterium of world wide estuarine environments, which concentrate on filter feeding shellfish. Under cooked seafood contaminated with this pathogen is a leading cause of 95% of seafood-related, foodborne deaths. The development of a rapid, reliable and user-friendly method for Vv enumeration would help to reduce mortality rate. A direct colony immunoblot (DCI) method was developed and used as a rapid enumeration with high sensitivity and the specificity. This method was optimized using Vv agar plates incubated for 16 h at 35 °C. Colonies were transferred from incubated plates to polyvinylidene fluoride (PVDF) membranes …
An Analysis Of The World Shrimp Market And The Impact Of An Increasing Import Base On The Gulf Of Mexico Dockside Price, Pawan Poudel
An Analysis Of The World Shrimp Market And The Impact Of An Increasing Import Base On The Gulf Of Mexico Dockside Price, Pawan Poudel
LSU Master's Theses
As a result of increased cultured activities, the world shrimp market has been expanded significantly during the past two decades. Because the growth in world supply has exceeded that of growth in demand, the deflated world shrimp price has fallen significantly since the mid-1980s. While a large producer of shrimp (primarily in the Gulf of Mexico), the United States is also the world’s largest importer. In general, the Gulf of Mexico dockside price is determined by the world export price and, as such, the Gulf of Mexico price has fallen sharply in recent years. This study quantifies the impact on …
