Online Journal of Rural Research & Policy

To compensate the US producers affected by the “trade war” with China, the United States Department of Agriculture (USDA) offered direct payments to producers using 2018 production levels under the Market Facilitation Program (MFP). Results of the revenue efficiency analysis of the MFP payments show the average producers in 12 out of 14 major corn and soybean producing states were compensated such that their 2018 per acre revenue was more than their 2017 per acre revenue. Conversely, an average producer in those states that experienced drought was under-compensated, as their total per acre revenue after the MFP payment was less ...

Crowdsourcing Change: An Analysis Of Twitter Discourse On Food Waste And Reduction Strategies, Annie R. Specht, Emily B. Buck

Journal of Applied Communications

Food waste has emerged as a major issue in the United States as the nation collectively sends more than 133 billion pounds of food to its landfills every year. In September 2015, the USDA and EPA announced an initiative to cut U.S. food waste in half by 2030. Between 2015 and 2016, nearly 100,000 posts about food waste have been published on Twitter, a microblogging platform that has been a hub of “slacktivism” since its inception in 2006. Using a conceptual framework of social cognitive theory, online activism, and crowdsourcing, we analyzed food waste conversation participants’ demographics, online ...


Evaluation Of Ancient Grains And Grain Free Dog Food On Nutrient Utilization And Stool Consistency In Dogs, Luis Lopez Apr 2019

Evaluation Of Ancient Grains And Grain Free Dog Food On Nutrient Utilization And Stool Consistency In Dogs, Luis Lopez

Kansas State University Undergraduate Research Conference

“Grain-free” and “ancient grain” claims have become popular in the pet food industry. However, there are no studies evaluating these types of diets. Thus, the objective of this study was to evaluate the effects of “grain-free” and “ancient grain” carbohydrate sources on nutrient utilization and stool consistency in dogs. Two dog diets were formulated to contain the same amount of carbohydrate sources: an ancient grain (AG) with spelt, millet, and sorghum, and a grain free (GF) with potato, pea, and tapioca starch. Experimental diets were fed to twelve Beagles housed in individual cages. This study was conducted as a completely ...

This project’s primary purpose was to identify and describe the leadership styles and skills emphases of current Kansas agricultural organization chief executive officers. Twenty-three current CEOs participated and were described in terms of their leadership styles, leadership-skills emphases, and demographics. Overall, they appeared to be rather “middle of the road” on each of the Multifactor Leadership Questionnaire’s nine leadership scales. Leadership styles were not significantly affected by demographics, with the exception of formal leadership training affecting transactional leadership and education level, organizational category, and staff size affecting passive-avoidant leadership. Participants generally rated the 50 leadership skills as important ...


Exploring Multi-Year Soybean Yield Trial Data In South Dakota Environments, Jixiang Wu, Jianli Qi, Jonathan Kleinjan Apr 2017

Exploring Multi-Year Soybean Yield Trial Data In South Dakota Environments, Jixiang Wu, Jianli Qi, Jonathan Kleinjan

Conference on Applied Statistics in Agriculture

Crop performance test (CPT) is a common practice to evaluate yield performance and adaptability of each cultivar. In this study, we combined 16 years of soybean CPT data, which included six representative locations, three major maturity groups, and over 1000 cultivars, to determine some patterns associated with yield production. As expected, the repeatability for these cultivars in trial over years was very low. Thus, the data processing in this study was focused on descriptive statistics regarding time, location, and seed supplier and several linear model analyses. The results will be presented during the conference.

Conference on Applied Statistics in Agriculture

In the area of veterinary medicine, efficacy studies are conducted to support licensure of vaccines. Such studies are typically designed to assess a vaccine's ability to prevent or mitigate clinical disease. For example, reduction of duration/severity of clinical signs or the severity of lung lesions are often considered as primary or secondary criteria of success. Studies designed to measure efficacy typically utilize two or more treatment groups and often use blocking structures to accommodate animal housing or litter related effects. When the criteria of interest are continuous or ordinal variables, as is the case with the above measurements ...


Statistical Methods For Assessing Individual Oocyte Viability Through Gene Expression Profiles, Michael O. Bishop, John R. Stevens, S. Clay Isom Jan 2017

Statistical Methods For Assessing Individual Oocyte Viability Through Gene Expression Profiles, Michael O. Bishop, John R. Stevens, S. Clay Isom

Conference on Applied Statistics in Agriculture

In vivo derived oocytes are held as the gold standard for viability, other known origination methods are sub-par by comparison. Due to the low-viability of oocytes originating from these alternate methods, research was conducted to determine and quantify the validity of these alternate origination methods. However, the larger question of viability is on the individual oocyte level. We propose and compare methods of measurement based on gene expression profiles (GEPs) in order to assess oocyte viability, independent of oocyte origin. The first is based on a previously published wRMSD quantification of GEP differences. We also consider three novel methods: a ...

Evaluating Adaptions Of Soft Red Winter Wheat In Eastern Region Of Usa, Dilmini Alahakoon, Anne Fennell, Jixiang Wu

Conference on Applied Statistics in Agriculture

Identification of winter wheat cultivars that are highly adapted to a wide range of environmental conditions is one of the most important wheat research objectives. Multi-environment crop trials under diverse environments is a commonly used practice to evaluate yield stability. For example, uniform eastern and southern red soft winter wheat nursery trials are conducted annually. However, locations and cultivars may vary from year to year and may cause yield stability analysis to be statistically challenging. In this study, we evaluated cultivars that were widely adapted to eastern production areas and those that were specifically adapted to other environments. We used ...
