Assessing The Efficiency Of Alternative Best Management Practices To Reduce Nonpoint Source Pollution In The Broiler Production Region Of Louisiana, Bryan Gottshall Jan 2013

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 Jan 2013

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 ...


A Linear Programming Model And Partial Budget Analysis To Optimize Management Strategies Of Western Flower Thrips In Greenhouse Impatiens Production, Xiaohua Yue Jan 2013

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 ...


An Analysis Of Consumer Preferences For Grass-Fed Versus Grain-Fed Beef, Bo Lin Jan 2013

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 ...
