An Examination Of Corporate Agribusiness Financial Performance: How Agribusinesses Perform Over Time And Under Various Conditions, Sierra J. Enlow

Theses and Dissertations--Agricultural Economics

While several studies examine the managerial structure of privately owned agribusinesses, few studies take a comprehensive look at publically traded agribusiness firms. Our study examines the historical position of agribusiness compared to the market, and then studies the impact of the global economic and financial crisis. The objective of this study is to pinpoint effects of corporate financial management strategies, commonly researched in financial literature on agribusiness firms’ performance. Through utilizing a quantile regression we find that agribusiness position in times of financial crisis is directly related to firm performance. As we examine internal factors, several interesting impacts of managerial …

Cultivating The Compass: Examining The Role Of Emotional Appraisal And Professional Agency Among Stakeholders In Kentucky Agricultural Education, Savannah Faye Robin

Theses and Dissertations--Community & Leadership Development

Agricultural Education has been informed by four major areas including agricultural education (teaching and learning), educational policy, agricultural policy (industry collaboration) and research. Historically agriculture teachers have been removed from the policy process affecting their profession in these four areas (Thompson, 1963). A review of historical literature suggests that only twice have teachers been involved in the policy process. The purpose of this study was to examine the involvement levels of stakeholders in agricultural education across the state of Kentucky. Specifically, examining the emotional appraisal of specific issues in agricultural education and if the emotions of stakeholders influence their involvement …

Evaluation Of Heat Shock Protein 70a (Hsp70a) In Chlamydomonas Reinhardtii, Sarah Nicole Short

Theses and Dissertations--Biosystems and Agricultural Engineering

Algae are being considered as a possible tool for carbon dioxide mitigation because they uptake carbon dioxide during photosynthesis. Using flue gas from a coal-fired power plant as a carbon source would allow the algae to remove CO₂ from the flue gas before it is emitted into the atmosphere. Because algae do not grow well at the high temperature, low pH conditions presented by flue gas, the traditional approach has been to alter the flue gas to suit the needs of the algae; however, this work aimed to genetically modify the algae Chlamydomonas reinhardtii to grow better at less …

Male Farmers Coping With Loss Of Spouse: Impacts On Farming Operation And Family Life, Daniel O. Wilson

Theses and Dissertations--Community & Leadership Development

Losing a spouse is as devastating an experience anyone will ever deal with in his or her life. Research, however, shows that men have a harder and longer time coping with the loss of a spouse than women. When the widower’s profession is farming, there are no resources to specifically help that individual with their loss. The purpose of this research was to gain insight into the lives of widowed farmers with particular focus on transitions in their farming operation and their family life. Through their stories, we learn what is happening before the loss of the female spouse on …

Development Of A Noncontact Sensor For Monitoring Milk Coagulation And Cutting Time Prediction In Cheese Making, Molly D. Craft-Jenkins

Theses and Dissertations--Biosystems and Agricultural Engineering

Cheese products are manufactured more consistently and with better quality if the curd cutting time can be consistently selected. An optical sensor that accurately predicts cutting time has been developed for large cheese vats, but the initial cost of these sensors makes them uneconomical for small artisan cheese manufacturers. The small artisan cheese vats require an inexpensive sensor technology that can be implemented simply. The initial cost of purchasing a sensor and installing these sensors plus the need for a computational program for implementing the algorithm make this technology excessively expensive for these smaller cheese manufacturers. The objective of this …

The Potential Application Of Weather Derivatives To Hedge Harvest Value Risk In The Champagne Region Of France, Andrew W. Yandell

CMC Senior Theses

In Champagne, France grape growers and and winemakers work together to make the world's most iconic sparkling wine. Part of what makes Champagne so celebrated is its reputation for constant quality: only the best grapes are used to make wine. In poor vintage years, grape growers sell less grapes to winemakers; poor vintages are the result of bad weather. This presents the opportunity for grape growers to hedge the risk of poor weather and resulting lower harvest values with weather derivatives. This study explores the potential for grape growers to trade them to effectively hedge against low harvest values by …

Are There Roles For Technical Communicators In Small Community Food Systems?, Brent William Chisholm

All Graduate Theses, Dissertations, and Other Capstone Projects

The author explores the viability of incorporating technical communication genres, practices, and theory, into various components of small community food systems. He argues that certain types of food systems and users in those food systems allow technical communicators to participate in ways aligning with genres of conservation writing described by Johnson-Sheehan and Morgan (2009). He also incorporates ideas about authorship, describing that technical communicators can improve food systems by reconciling disparate agricultural technical material, advocacy for action, and the articulation of previously non-existent food systems.

Characteristics Of Kentucky Agricultural Operations Participating In Nrcs Conservation Programs, Carmen T. Agouridis

MPA/MPP/MPFM Capstone Projects

The Natural Resource Conservation Service (NRCS) designs and promotes a wide variety of conservation practices and programs that enhance the environment by reducing soil erosion, improving water quality, and enhancing and creating wildlife habitat. The impact of these practices and programs is largely dependent on the voluntary participation of landowners. Thus, central to the success of the NRCS conservation programs is an understanding of the characteristics of landowners and operations participating in these programs.

Using operator and operation characteristics from the 1997, 2002, and 2007 Censuses of Agriculture and controlling for county fixed effects, this study 1) identifies significant characteristics …

Enabling Learning And Enhancing Education In Ipm In The Midst Of Dwindling Financial Resources: Why Open Access To Resources And Publishing Could Be A Strategic Step To Support Students Today And Tomorrow?, Ousmane Youm

Department of Entomology: Faculty Publications

When I was invited to join the editorial board of the journal Entomology, Ornithology & Herpetology (EOH), I read carefully the note coming with the invitation and also looked at the content and scope. Then two things came into my mind as I stopped a few minutes to reflect on a couple of issues: (1) how the new journal links and is relevant to Integrated Pest Management—IPM (for those who understand its definition)—and (2) the issue of open access and relevance in the current situation of an ailing global economy, particularly in the vulnerable developing nations.

In the latter, more …

Great Plains Soils May Be C Sinks, David E. Clay, Gregg C. Carlson, Sharon A. Clay, James Stone, Kurtis Reitsma, Ronald Gelderman

Agronomy, Horticulture and Plant Science Faculty Publications

Numerous studies with wide-ranging results have been conducted to resolve if Great Plains soils are a C source or sink. The authors addressed the source/sink question by examining the results from producer soil samples and production surveys that were analyzed and archived by the South Dakota Soil Testing Laboratory. Results showed that between 1985 and 2010, soil organic C content increased at a rate of 326 lb C/A/year, for a total increase of 24%. The increase was attributed to planting better adapted varieties and using better management practices that on average increased corn grain yields 2.29 bu/A/year. Higher soil organic …

Soil Microbial Community Response To Climate Change: Results From A Temperate Kentucky Pasture, Lindsey C. Slaughter

Theses and Dissertations--Plant and Soil Sciences

Climate change is likely to alter plant species composition and interactions between plants and soil microbes that together dictate the quantity and quality of forage produced in pastures, the base of animal production in central Kentucky. This study assessed the seasonal dynamics of soil microbes and their response to increased temperature (+3^oC) and growing season precipitation (+30% of the mean annual). Total soil microbial biomass, community composition, enzyme activities, potential carbon mineralization, and catabolic responses to selected substrates were measured seasonally in the different climate treatments. In this system, seasonal variability was a dominant driving factor for all …

Using An Active Optical Sensor To Improve Nitrogen Management In Corn Production, Donato Titolo

Theses and Dissertations--Plant and Soil Sciences

Corn nitrogen (N) applications are still done on a field basis in Kentucky, according to previous crop, soil tillage management and soil drainage. Soil tests, as well as plant analysis for N, are not very useful in making N fertilizer rate recommendations for corn. Recommended rates assume that only 1/3 to 2/3 of applied N is recovered, variability largely due to the strong affect of weather on the release of soil N and fertilizer N fate. Many attempts have been made to apply N in a more precise and efficient way. Two experiments were conducted at Spindeltop, the University of …

Factors Influencing Price Volatility On Soybeans Futures Prices, Diego J. Gavilanez Hernandez

LSU Master's Theses

Recent unexpected changes (mid-2007- Aug 2011) in agricultural commodity markets have led stakeholders to ask if the volatility of futures prices currently observed are still the result of traditional fundamentals. Consequently, the purpose of this research was to identify those factors that affect monthly soybeans futures price volatility. To accomplish this study, four relevant factors are explored. First, the integration between energy and agricultural markets is accounted for via oil spot prices, as well as a dummy variable to account for the shift in the U.S renewable fuel policy since 2007. Second, the increasing consumption of commodities from China is …

The Economic Feasibility Of Utilizing Energy Cane In The Cellulosic Production Of Ethanol, Kayla Lynn Brown

LSU Master's Theses

With an overall lack of economic information available on energy cane production, the aim of this research has been to provide some insight on the economic feasibility of producing energy cane in Louisiana as a feedstock for cellulosic ethanol production. When dealing with a non-traditional crop such as energy cane, increased uncertainty surrounding potential costs and returns can make the crop seem much less appealing to potential producers. As a high-fiber hybrid of traditionally produced sugarcane, energy cane production costs have been estimated using a standard enterprise budgeting approach developed for sugarcane, along with actual yield and fiber data from …
