Leading Horses To Water During A Pandemic: Assuring Communication Learning For "Quants", Thomas Hall
International Journal for Business Education
Students who are attracted to quantitative disciplines of study can be reluctant to devote much attention to the important task of communicating, and previous research (Hostager, 2018) has identified statistically significant differences in learning approaches by major among undergraduate business students. This paper presents results of learning assurance for writing skills (direct measures) even when the content of the course relates to the highly quantitative topics of data analytics and finance. The approach combines various pedagogical methods in an undergraduate, writing-intensive setting: traditional testing but in an iterative framework, “flipped classroom” intensive work using spreadsheet software, repeated submission of brief …

Can Machine Learning Models Provide Accurate Fertilizer Recommendations?, Takashi S. T. Tanaka, Gerard B. M. Heuvelink, Taro Mieno, David S. Bullock
Department of Agricultural Economics: Faculty Publications
Accurate modeling of site-specific crop yield response is key to providing farmers with accurate site-specific economically optimal input rates (EOIRs) recommendations. Many studies have demonstrated that machine learning models can accurately predict yield. These models have also been used to analyze the effect of fertilizer application rates on yield and derive EOIRs. But models with accurate yield prediction can still provide highly inaccurate input application recommendations. This study quantified the uncertainty generated when using machine learning methods to model the effect of fertilizer application on site-specific crop yield response. The study uses real on-farm precision experimental data to evaluate the …

Will Saf Turbocharge The Corn Ethanol Market?, Richard K. Perrin, Lilyan E. Fulginiti, Felipe Miranda De Souza Almeida
Cornhusker Economics
The long-run outlook for the corn ethanol industry is questionable, due to a transition to electric and hybrid vehicles. One source of hope for the long run is the potential demand for producing Sustainable Aviation Fuel (SAF). SAF is a key component in the United States Aviation Climate Action Plan, a path to net-zero greenhouse gas (GHG) emissions in the aviation industry by 2050. Demand for ethanol for SAF offers hope to the ethanol industry, but it depends a great deal on policy decisions that are being made now. Here we sketch out this story.

Autonomous Roadside Mower Testing And Evaluation In Digital Twin Environments, Michael Mardikes, Ethan Brown, Timothy Wiegman, Nathan Sprague, Shreyas Supe, J. T. Evans
Graduate Industrial Research Symposium
Modern day roadside mowing operations in Indiana are performed by contractors operating tractors that pull flex-wing mowers. These mowing operations span over 11,000 miles of road across the state and create serious risk for human operators. Autonomous mowers can provide a safer alternative, but a replacement system must demonstrate an acceptable level of trust before large-scale deployment. A high-fidelity digital-twin environment can facilitate the capability to rapidly test and evaluate platforms in their desired application, while enabling zero real-world risk, a wide range of test variables, and repeatability of a test setup. The simulation environment must be at a level …

Mulching practice offers farmers an opportunity to minimize the effects of drought, water loss, and soil erosion on crop production. Plastic film is widely used as a mulching material; however, contamination of arable lands by residual plastic has become a serious concern. Synthetic biodegradable mulch films and sprays may offer a more sustainable alternative to plastic films, however current evidence on the factors that influence the suitability of these products for agricultural applications is fragmented, making it unclear under what conditions these products meet agronomic, environmental, and societal needs. We address this gap by conducting a systematic review of studies …

This study examines the effect of social learning on new turfgrass variety adoption decisions using data from 231 turfgrass professionals’ Twitter accounts between 1 Jun 2018 and 31 Dec 2019. To determine the social learning effect, we decompose networking effects into social learning, individual-level and group-level similarities, herd behavior, and clustering effects. Our study estimates a spatial autoregressive probit model that directly incorporates the social network structure to account for unobservable networking effects and potential reflection problem. A Bayesian estimation procedure is used to alleviate the convergence problem caused by the complexity of model specification. Empirical results show that the …

Public–Private Partnerships In Strengthening Rural Food Supply Chains: A Financial And Operational Model For Federal Collaboration, Sarah Onyeche Usoro, Aminat Adebukola Amunigun
Student Publications
Rural food supply chains in the United States exhibit structural fragility, chronic underfunding, and limited integration with federal investment mechanisms. Cold storage capacity remains inadequate, aggregation infrastructure is sparse, and processing and last-mile distribution face persistent bottlenecks across much of rural America. These domestic conditions reflect a broader global pattern: the FAO estimates that approximately 733 million people faced hunger in 2023, with rural populations bearing a disproportionate share of that burden [1]. This paper addresses the domestic dimension of that challenge by synthesizing the existing literature on public–private partnerships (PPPs) in food systems infrastructure and proposing an original financial …

Rice is a crucial contributor to global food security and is an important staple for over half the world's population. Irrigated paddy rice is a water-intensive crop, and an important contributor to greenhouse gas emissions. Thus, improving the efficiency of using rice as food rather than non-food uses is paramount to sustainably feeding a growing global population. One source of inefficiency in the rice market is using broken rice for non-food purposes. This study focuses on consumer preferences for rice with different broken percentages in Colombia. We used a mixed-method approach to ascertain the stated (experimental setting) and revealed (using …

Reducing micronutrient malnutrition (“hidden hunger”) in low-income countries is a global challenge, particularly among women, children, and high-poverty households. Countries like Tanzania have developed diverse strategies to combat malnutrition, including the biofortification of staple foods. However, broad awareness and knowledge of micronutrient deficiencies and beneficial foods are needed for these strategies to be effective. The objectives of this study were to (i) examine Tanzanian consumers' initial awareness and knowledge of deficiencies for four micronutrients and associated biofortified foods, and (ii) to examine the effectiveness of targeted communication approaches (i.e., information and branding) to improve knowledge. Data were collected from 1029 …

In a multi-year survey of potential job seekers, those who are likely to change jobs in the next year or who are likely to reenter the workforce in the next year, several key training obstacles for improving their employment situation were identified. There seemed to be only slight differences in how they viewed these challenges, regardless of whether they saw their potential job as a career, a steppingstone to a career, or just a job to get by. The cost of training, the lack of available training, the distance or transportation to the training, lack of time, and the knowledge …

New breeding methods have provided scientists with opportunities to improve traits in a wide range of crops, however, there remains resistance to foods that are produced from these crops, and mandates on labels used to describe such processes continue to be a source of policy debate. Here we focus on gene editing and examine (i) whether consumer acceptance varies when the technology is applied to different ingredients (unrefined versus highly refined ingredients) and (ii) the impact of two different claims related to gene editing (health-focused claim versus an environment-focused claim). Our results show that consumers are less likely to purchase …

Predicting Sedentarism And Its Impact On Caloric Requirements, Jacob Michels, John C. Beghin
Yeutter Institute International Trade Policy Review
A recent study conducted by PhD candidate Jacob Michels and Agricultural economist John Beghin delves into the question of whether global estimates of food insecure populations need a reevaluation of their methodology to account for increasing sedentarism. This reevaluation is prompted by the increasing prevalence of sedentary lifestyles worldwide, which calls for a redefinition of caloric thresholds indicating the onset of food insecurity. In this short article, we provide a nontechnical summary of their investigation recently published in Michels and Beghin (2024).

Slight Cost Of Production Changes Noted In The 2024 Nebraska Crop Enterprise Budgets, Glennis Mcmclure
Cornhusker Economics
The Nebraska crop budgets are available for the 2024 production season. The 84 enterprise budgets prepared in the October 2023 timeframe use input prices collected as of that time. Overall, estimates reflect slight cost of production decreases in the budgets when compared to the 2023 cost estimates. For 2024, the main drivers of cost decreases are due to decreased fuel and fertilizer costs. In some cases, pesticide costs decreased, yet for some of those products, prices increased. Seed and interest costs have increased for 2024 adding to cash expenses, while land opportunity costs and depreciation costs have continued to rise …
