Work Ethic And Productivity: The Mediating Role Of Leadership, Everly Tapp

Murray State Theses and Dissertations

Employee work ethic and workplace productivity are vital for organizational success. Past research has shown leadership style to be influential on both, with the manager-employee relationship impacting employee’s attitude and output in the workplace. This study investigated the relationship between employee work ethic and workplace productivity, while also examining the impact of transformational, transactional, and laissez-faire leadership styles on agriculture equipment dealership employees. The leadership style of service managers, as measured by the Multifactor Leadership Questionnaire (MLQ) (5x-Short), was compared to the workplace productivity and work ethic scores of the service technicians they manage. Service technician workplace productivity data was …

Exploring The Determinants Of Aspects Of Rotational Grazing In The U.S. Great Plains, Iftekhar Uddin Ahmed Chowdhury

Electronic Theses and Dissertations

Pasture and rangeland make up about 45 percent of the agricultural land in the U.S. Great Plains and one of the most common form of mismanagement of this pasture is overgrazing. Which results in many detrimental effects on environment. Many practitioners endorsed Rotational grazing (RG) as an improved grazing management practice over season-long continuous grazing. The overall goal of the current study is to assess the certain aspects of using RG in the U.S. Great Plains. Using mail survey data of the of 874 beef cattle producers of North Dakota, South Dakota, and Texas, the study found that neighborhood practice, …

Two Essays On Food Environment, Nutrition, And Food Insecurity, Suliman Abdulaziz Almojel

Theses and Dissertations--Agricultural Economics

A healthy food environment is fundamental to good health. It contributes to the reduction of obesity and the development of healthy eating habits. In spite of this, many people in the United States (US) have been hypnotized to become obese due to the current food environment. Recently, the US has consistently ranked high in the world in terms of obesity. The rising rate is symptomatic of consuming unhealthy diets. Besides, the double-edged crisis of the US food environment and obesity poses a major threat to food security and public health. Therefore, studying the US food environment is important to sustain …

A Decision Tool To Identify Population Management Strategies For Common Ravens And Other Avian Predators, Andrea F. Currylow, Brenda J. Hanley, Kerry L. Holcomb, Timothy Shields, Stephen Boland, William I. Boarman, Mercy Vaughn

Human–Wildlife Interactions

Some avian species have developed the capacity to leverage resource subsidies associated with human manipulated landscapes to increase population densities in habitats with naturally low carrying capacities. Elevated corvid densities and new territory establishment have led to an unsustainable increase in depredation pressure on sympatric native wildlife prey populations as well as in crop damage. Yet, subsidized predator removal programs aimed at reducing densities are likely most effective longer-term when conducted in tandem with subsidy control, habitat management, and robust assessment monitoring programs. We developed decision support software that leverages stage structured Lefkovitch population matrices to compare and identify treatment …

Incorporation Of Summer Annual Mixtures Into Grazing Systems In Kentucky, Kelly Marie Mercier

Theses and Dissertations--Plant and Soil Sciences

Utilizing summer annual grass-legume forage mixtures has the potential to improve forage yield and nutritive characteristics, and/or animal performance during times when cool-season pasture growth is limited by high temperatures. Legumes can utilize atmospheric nitrogen, which can increase crude protein and forage digestibility in mixtures. As nitrogen application generally improves both the yield and nutritive characteristics of summer annual forages, but can have a negative effect on legume competitiveness, nitrogen fertilizer recommendations for legume-containing summer annual mixtures are not well established.

Two experiments were conducted to determine the feasibility of utilizing summer annual mixtures in Kentucky, USA. The first experiment …

A Snowball Effect: A Pandemic’S Impacts On Household Food Insecurity In The United States, Sidie Sahid Sisay

Dissertations and Theses

Economic insecurity exists whenever income sources are uncertain, and this is a failure of a fundamental human right. The Covid-19 pandemic has presented unprecedented disruptions to the US economy and has created unparalleled food insufficiency and economic hardships. Before the pandemic, household food insufficiency existed but downplayed in the political arena. In 2019, 10.5 percent of households in the US lived in extreme poverty and were food insecure, the lowest since 1959, but the pandemic has had devastating effects on household food insufficiency. This paper uses nationally representative data from the Census Bureau’s weekly household pulse survey, coupled with standard …

Pumping Fees And Spillovers In The Groundwater Commons: An Evaluation Of A Conservation Tool And Irrigator Competitive Behavior, Godwin Kwabla Ekpe

Graduate Research Theses & Dissertations

My dissertation examines the effectiveness of pumping fees in groundwater commons agricultural irrigation as a conservation tool in the presence of varying water scarcity levels and spatial interdependence among irrigators. The first chapter provides a brief overview of three important areas of groundwater commons irrigation addressed in this dissertation. The second chapter’s objectives are two-fold. First, I review the common-pool resources literature relative to concerns of sustainable extraction and implementation of conservation policies focusing on pricing incentives in the management of groundwater commons where irrigators share the same underlying aquifer. Second, I introduce a theoretical model involving incorporating a non-constant …

Genetically Modified Corn Diffusion And Biofuel Usage: Impacts On Corn Belt Cropping Systems Changes, Kenneth Annan

Electronic Theses and Dissertations

The adoption of genetically modified (GM) crops, the rise of ethanol production that produced an additional derived demand for corn, and the increasingly prominent position of corn and soybeans in crop rotations embody major changes in U.S. agriculture during the past decades. This study investigates the linkages among these developments in two ways. First, we look at how biotechnology and biofuels have influenced cropping system changes in the Corn Belt region of the United States, using state-level data from 2000 to 2019. Second, we investigate the determinants of corn acreage intensification levels and heterogeneity at the state level using data …

On The Use Of Virtual Reality In Mitigating Hypothetical Bias In Choice Experiments, Di Fang, Rodolfo M. Nayga Jr., Grant H. West, Claudia Bazzani, Wei Yang, Benjamin C. Lok, Charles E. Levy, Heather A. Snell

Agricultural Economics and Agribusiness Faculty Publications and Presentations

Choice experiments have been extensively used in many stated preference studies and disciplines. In order to give external validity to stated preferences, participants must behave the same in an experiment setting as they do in reality. The difference between a decision made in a real experiment and a hypothetical experiment is commonly attributed to "hypothetical bias." In this paper, we investigate whether virtual reality can reduce hypothetical bias in choice experiments. We conducted a set of experiments using the Food and Drug Administration's new Nutrition Facts Label for yogurts. Participants were randomly assigned to non-hypothetical and hypothetical experiments, which differed …

Capparis Decidua Edgew (Forssk.) Stem Extract Alleviates The Water Stress Perturbations In Wheat (Triticum Aestivum L.) At Early Growth Stage, Muhammad Nawaz, Qasim Ali, Muhammad Azeem, Fehmina Asghar, Hasnain Ishaq, Naeem Iqbal, Sajid -Ur-Rahman

Journal of Bioresource Management

Water shortage is one of the major limiting factors of crop productivity worldwide. This study was planned to explore the impact of Capparis decidua stem extract on wheat varieties (FSD-2008, 12066 and 13348) under water stress condition. Water deficit condition negatively impacted the seedling germination, growth, photosynthetic pigments and ions uptake capacity. Water limited condition significantly (p≤0.05) increased time to attain 50% germination, lipid peroxidation, H₂O₂ and enhanced the antioxidant mechanism to overcome the oxidative stress. Different concentrations of C. decidua extract i.e. Not Soaking (NS), 10%, 20%, 30% and 40% were used for seed …
