A Linear Programming Model And Partial Budget Analysis To Optimize Management Strategies Of Western Flower Thrips In Greenhouse Impatiens Production, Xiaohua Yue
LSU Master's Theses
The research problem of this thesis was to compare strategies and costs of protecting impatiens in greenhouse culture from western flower thrips that would provide a plant of acceptable quality to the market and would address the issue of development of resistance to commonly used pesticides by evaluating biopesticides. Partial budgets based on alternative strategies were identified. Six control strategies were identified from a combination of commercial growers, research experts and biopesticide recommendations from product distributors. The research-recommended strategy 6 had the highest total production cost ($197.44), while one of the grower strategies based on conventional pesticides had the lowest …
The Effects Of U.S. Shrimp Imports On The Gulf Of Mexico Dockside Price : A Source Differentiated Mixed Demand Model, Maryam Tabarestani
The Effects Of U.S. Shrimp Imports On The Gulf Of Mexico Dockside Price : A Source Differentiated Mixed Demand Model, Maryam Tabarestani
LSU Doctoral Dissertations
The ever increasing demand for the shrimp products in the 1980s and 1990s caused the volume of shrimp imports to increase. The import of shrimp has had an upward trend, from 847 million pounds in 1997 to 1,636 million pounds in 2010.The imports price has declined since 1997. Along with the decrease in imports price, the U.S. domestic shrimp price has also declined. However, the annual production of shrimp from the Gulf of Mexico has, in the long-run, remained relatively stable. These facts indicate that there is not the same quantity-price relation between the U.S. domestic shrimp market and shrimp …
Empirical And Simulation Essays On Analyzing A Country's Export Performance : The Case Of Ghana, Aude L. Pujula
Empirical And Simulation Essays On Analyzing A Country's Export Performance : The Case Of Ghana, Aude L. Pujula
LSU Doctoral Dissertations
A large array of literature has revealed the complexity of export performance analysis. Using the case of Ghana, this dissertation, divided into three essays, seeks to provide the methodological guidance, empirical and simulation evidence necessary to analyze a country’s export performance. The choice of Ghana was motivated by the country’s growth experience, strong export and agricultural sectors and implemented reforms and programs since 1983. In the first essay, we created a new trade-weighted Cedi index or real effective exchange rate (REER) that takes into account Ghana’s most relevant patterns of trade and captures the evolution of Ghana’s export price competitiveness …
Environmental Kuznets Curve In Water Pollution: A Semiparametric Approach, Mahesh Pandit
Environmental Kuznets Curve In Water Pollution: A Semiparametric Approach, Mahesh Pandit
LSU Doctoral Dissertations
The relationship between pollution and per capita income generally appears as an inverted U-shaped curve. This inverted U-shaped curve is known as the environmental Kuznets curve (EKC). The shape of the curve, however, is very sensitive to the data, location and pollutant considered in the analysis. Since the early 1990s, there has been an exponential growth in the number of empirical studies in this field, but many refute the inverted U-shaped nature of the curve for pollutants across different time periods and geographical regions. This has generated an increased interest in developing a more flexible functional form for model specification …
Consumer's Preferences For Goat Meat In The United States : An Application Of Choice-Based Conjoint Analysis, Jessica Irene Hill
Consumer's Preferences For Goat Meat In The United States : An Application Of Choice-Based Conjoint Analysis, Jessica Irene Hill
LSU Doctoral Dissertations
The meat goat industry is one of the fastest growing agricultural sectors in the United States. However, there has been limited research on consumers’ preferences for goat meat; therefore, a choice experiment was used to assess consumer preferences for goat meat and/or live goats. A national online survey was conducted from April 27, 2012 to May 4, 2012. Respondents were asked to complete either the goat meat choice experiment, live goat choice experiment or both. In addition to the choice experiment, respondents answered a set of questions about goat meat consumption and purchasing behavior as well as demographics. The attributes …
An Analysis Of Consumer Preferences For Grass-Fed Versus Grain-Fed Beef, Bo Lin
An Analysis Of Consumer Preferences For Grass-Fed Versus Grain-Fed Beef, Bo Lin
LSU Master's Theses
As a consequence of the growing concerns about human health and the environment, consumers are becoming more interested in grass-fed beef than conventional grain-fed beef. Therefore, the study of consumers’ preference towards grass-fed versus grain-fed beef steak is the focus of research. In this paper, 2,000 respondents who indicate they have eaten grass fed beef in the past years and 2,000 respondents that complete a nationally representative sample is the general population. Conjoint analysis is utilized to analyze the preference of consumers. Participants are presented ten hypothetical beef steaks to rate. All steaks are identical excluding their product type, source …
Assessing The Efficiency Of Alternative Best Management Practices To Reduce Nonpoint Source Pollution In The Broiler Production Region Of Louisiana, Bryan Gottshall
Assessing The Efficiency Of Alternative Best Management Practices To Reduce Nonpoint Source Pollution In The Broiler Production Region Of Louisiana, Bryan Gottshall
LSU Master's Theses
The Louisiana broiler production region is located in North Central and Northwestern Louisiana. The region consists of twelve parishes in Northwestern and North Central Louisiana. The broiler production region is a significant contributor of nonpoint source (NPS) pollution to nearby waterways. This pollution is a consequence of sediment, nitrogen and phosphorus runoff caused by agricultural production. NPS pollution is difficult to mitigate due to uncertainties in its point of origin as well as a host of other factors ranging from rainfall to topographical parameters. Best Management Practices (BMPS) have been shown to be a reliable method for reducing nonpoint source …
Quality Of Care: Analyzing The Relationship Between Hospital Quality Score And Total Hospital Costs, Jordan Andrew Newell
Quality Of Care: Analyzing The Relationship Between Hospital Quality Score And Total Hospital Costs, Jordan Andrew Newell
LSU Master's Theses
As healthcare costs and premiums have increased in the recent past, hospitals are forced to try to provide healthcare on tight budgets. In many cases, quality is often sacrificed in an effort to manage patient wait-times and costs. This research attempted to add to the existing body of knowledge of quality of care by defining a relationship between quality of care provided and total hospital costs. This study used the 2006 American Hospital Association’s Annual Survey Database and the 2006 Hospital Compare dataset to meet the data requirements for the study. A log-log, as well as a translog, cost function …
