Are Some Analysts Superior At Forecasting World Grain Supplies?, Emmie M. Noyes

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Whether agriculture is how you make your living or simply a means of putting food on your table, the prices of agricultural commodities and products affect us all. When buying and selling agricultural commodities, both farmers and firms use futures markets. Futures markets help minimize price risk, which is important to both sides of the transaction.

Recently, private analysis firms have started to forecast the information contained in the USDA’s WASDE report. This is relevant because future prices react to new information contained in WASDE reports. These firms will release their information a few days before the WASDE comes ...


Factors Affecting Graduation With Honors: A Case Study In Business, William Litzinger 2022 University of Arkansas, Fayetteville

Factors Affecting Graduation With Honors: A Case Study In Business, William Litzinger

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Many first-year college students elect to enroll in their university’s honors program. These programs offer students many educational benefits not provided to non-honors students, such as smaller class sizes, priority registration, and added faculty interaction. However, of the students that enter the university as an honors student, many fail to complete their honors program. Researchers have documented completion rates as low as 18.45% (Campbell and Fuqua, 2008). So why are honors graduation rates so low? In this study, variables were examined that the literature suggests affects honors graduation rates (High School GPA, ACT/SAT scores, AP credits, GPA ...

Targeting Inflammation In Heat-Stressed Wethers Improves Growth And Efficiency And Alters Body Composition; A Brief Exploration And Application Of Extension Principles, Micah Most 2022 University of Nebraska-Lincoln

Targeting Inflammation In Heat-Stressed Wethers Improves Growth And Efficiency And Alters Body Composition; A Brief Exploration And Application Of Extension Principles, Micah Most

Theses and Dissertations in Animal Science

The objective of our first study was to determine how administering anti-inflammatory dexamethasone and ω-3 polyunsaturated fatty acid (PUFA)-rich fish oil affects growth efficiency and body composition in heat-stressed finishing lambs. Commercial wethers were randomly assigned to be fed under heat stress (35°-40℃) or thermoneutral (19℃, n = 10) conditions for 30 d, and controls were pair-fed to eliminate differential feed intake. Heat-stressed wethers were randomly assigned to receive clinical-dose dexamethasone IM injections every 72 h, twice daily fish oil capsule oral boluses, or placebos. Heat stress decreased (P < 0.05) growth and efficiency, but dexamethasone and fish oil supplementation recovered these performance measures. Heat stress also decreased (P < 0.05) predictive body composition metrics that were at least partially improved by administration of dexamethasone and fish oil. Proximate analyses of muscles showed that heat stress decreased (P < 0.05) percentage of protein and increased (P < 0.05) percentage of intramuscular fat, neither of which was improved by dexamethasone or fish oil. Immunohistochemistry revealed that heat stress decreased (P < 0.05) myoblast differentiation and muscle fiber size, but anti-inflammatory supplementation recovered differentiation only. Plasma IGF-1 concentrations were not different among groups throughout the study. These findings demonstrate how heat stress-induced inflammation contributes to impaired growth, efficiency, and body composition observed in heat-stressed feeder lambs. However, targeting inflammation with dexamethasone or fish oil recovers many of these deficits.

The Cooperative Extension Service, created in ...

First Line Of Defense: Role Of Surface Waxes In Sorghum Defense Against Aphids, Juan David Betancurt Cardona

Dissertations and Student Research in Entomology

Since 2013, the sugarcane aphid (SCA; Melanaphis sacchari) has become a devastating pest in sorghum (Sorghum bicolor) in the United States. Efforts to mitigate this pest and contain its rapid population growth have increased recently. Host plant resistance (HPR) is an effective and environmentally friendly strategy to reduce aphid populations in this crop. Many factors make SCA a challenging pest to control. For example, SCA can overcome drastic climatic changes, which allows them to successfully colonize sorghum plants at different developmental stages.

Epicuticular waxes (EW) constitute the first point of contact between plants and their environment. EW differ in their ...

Interactions Between Resistance Genes In Wheat Triticum Aestivum L. And Wheat Curl Mite Populations Aceria Tosichella Keifer (Eriophyidae), Tran Kim Ngan Luong

Dissertations and Student Research in Entomology

Wheat curl mite (WCM) (Aceria tosichella Keifer) is a major pest of winter wheat (Triticum aestivum L.), being the only known vector of three damaging plant viruses, Wheat streak mosaic virus, Triticum mosaic virus, and High Plains wheat mosaic virus. This wheat-mite-virus complex causes significant yield loss globally. Management has been mostly through cultural practices to reduce mite build up in volunteer wheat, thereby reducing the spread of viruses. Host plant resistance to WCM has also been used as an important management strategy for this wheat-mite-virus complex. However, WCM is a cryptic species complex, resulting in great variability in WCM ...
