An Exploration Of Learning And Teaching Methods In Agricultural Extension, Jeremy Levinson, Dave Lamie, Michael Vassalos, Chris Eck, Juang Chong, Francis P. F. Reay-Jones

The Journal of Extension

Abstract

The Train-the-Trainer approach is widely used in Cooperative Extension education to efficiently disseminate research-based information to many clientele groups, including farmers. This paper compares the traditional Train-the-Trainer model to a comprehensive Collaborative Train-the-Trainer model and discusses weaknesses of the traditional model that are addressed in the Collaborative model. Sources of information used by farmers (growers) and overall effectiveness were measured through a survey instrument created and distributed to farmers in South and North Carolina. The Collaborative Train-the-Trainer model, which emphasizes peer-to-peer interaction and feedback loops, represents an enhanced approach for conceptualizing and implementing Extension educational programs.

Preliminary Analysis Of Native Bee Community Adjacent To Sorghum And Wheat Fields In Western Kansas, Katelyn Strack, Sarah Elzay

SACAD: John Heinrichs Scholarly and Creative Activity Days

Agricultural practices have significant and often negative effects on native bee populations. It is imperative that we understand how current agricultural practices affect native bees. Sorghum (Sorghum bicolor) is cultivated heavily in western Kansas and is grown in rotation with winter wheat. This analysis presents preliminary results from a study conducted in summer 2023 in which pan traps were placed adjacent to two sorghum and two wheat fields in Ellis Co. Kansas. This data is part of a larger study examining the relationship between native bees and sorghum in western Kansas.

Contrasting Tick Species Behaviors: A Course-Based Undergraduate Research Experience (Cure), Sara Benham, Shovan Dutta, Rohan Maddamsetti, Clayton Wright, Alena Anderson, David T. Gauthier, Holly D. Gaff

Spora: A Journal of Biomathematics

Tick-borne diseases are on the rise throughout the world, and there is a need to better understand tick behavior in order to identify potential new interventions. Ticks have a complex life history and can survive months off-host. There is a lack of large-scale data on off-host tick behavior, which leaves a gap in understanding of tick biology outside of tick-host interactions. Introducing undergraduate students to authentic research early in their studies can help prepare them for independent inquiry in upper-level classes. To address the student needs and fill gaps in tick research, students in introductory biology courses recorded observations of …

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Obesity affects adults in the United States, leading to chronic diseases and reduced well-being. Time-Restricted Feeding (TRF) is a type of dietary intervention lacking current data regarding the effectiveness on facets of well-being. This study’s objective was to determine the effect of time-restricted feeding supplemented with whey protein isolate on food intake, sleep, and mood in overweight or obese adults. Nineteen participants were randomly assigned to the control or experimental group: 1) control, TRF, and 2) experimental, TRF with whey protein supplementation. Participants followed the assigned dietary intervention for 12 weeks. Every 4 weeks (baseline, week 4, week 8, and …

Rice Biomass Response To Various Phosphorus Fertilizers In A Phosphorus-Deficient Soil Under Simulated Furrow-Irrigation, Jonathan B. Brye, Kristofor R. Brye, Diego Della Lunga

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Wastewater-recovered phosphorus (P), in the form of the mineral struvite (MgNH4PO4∙6H2O), may provide a sustainable alternative to decreasing rock-phosphate reserves. Struvite can be generated via precipitation methods, potentially reducing the amount of P runoff to aquatic ecosystems. The objective of this greenhouse tub study was to evaluate the effects of chemically and electrochemically precipitated struvite (CPST and ECST, respectively) on aboveground plant response in a hybrid rice cultivar grown using furrow-irrigation compared to other common fertilizer-P sources [i.e., triple super phosphate (TSP) and diammonium phosphate (DAP)] using three replications of fertilizer treatment in a P-deficient silt loam (Typic Glossaqualfs). Aboveground …

Effects Of Cyclic Heat Stress On The Acute Inflammatory Response In Broilers, Alessandro J. Rocchi, Chrysta N. Beck, Jossie M. Santamaria, Gisela F. Erf

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Heat stress (HS) is a growing concern in broiler production. Little is known regarding the effect of HS on immune function. To examine the effects of HS on innate immunity, the local- and systemic-inflammatory responses to lipopolysaccharide (LPS) were examined in Cobb 500 male broiler chicks reared under thermoneutral (TN) or cyclic HS conditions. Beginning at four days of age, HS birds were subjected to 35 °C from 8:00 a.m. to 10:00 p.m. and TN temperatures from 10:00 p.m. to 8:00 a.m. At 37 days of age, four groups of broilers were formed: LPS-TN (8 broilers), phosphate-buffered saline (PBS)-TN (4 …

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The purpose of this project was to help children reach more developmental goals and to make outdoor play at the Jean Tyson Child Development Study Center more inclusive for all children. Children gain many developmental goals from playing outside and being exposed to other environments as compared to just being inside the classroom. Outdoor play should be as inclusive as indoor play and offer many different activities and outlets, just as the indoor classroom does. The implementation of this service-learning creative project was to add more versatility to the outdoor area at the University of Arkansas Jean Tyson Child Development …

The Abcdefgs Of Entomology, Maria T. Gutierrez

Department of Entomology: Distance Master of Science Projects

As a parent of three kids, I love finding ways to spark their curiosity and love for learning, so combining my interest in entomology and my experience as a parent, I came up with a fun yet informative book about insects. I selected the most common insects kids might encounter daily at home, school, or while playing at the park: ants, butterflies, cockroaches, dragonflies, earwigs, flies, and grasshoppers.

I aimed to develop an activity book that anyone could use, whether they are a teacher or a parent without a scientific background. By focusing on these seven specific insects, I wanted …

Entomology Outreach Presentations To Four Audiences, Michael Goldman

Department of Entomology: Distance Master of Science Projects

I proposed that my master’s Project would be outreach on Entomology at four levels: School aged children, laymen, non-entomologists in a technical field, and entomologists. The idea here is basically how to talk about entomology to varying levels of expertise, from first graders to experts in both entomology and occupational health and safety. Presentations were given to audiences at each of the four levels. The specific topics varied for each audience. The determination was made by the inviting audience in the cases of school aged children and adult laymen and by me in the cases of Occupational Safety and Health …

A Short Introduction To Marine Parasitology: Marine Parasites Of Economic And Medical Importance, Klaus Rohde, Robin M. Overstreet

Concepts in Animal Parasitology Textbook

Introduction

Parasitism, in this chapter, is defined as “a close association of two organisms, in which one—the parasite—depends on the other—the host—deriving some benefit from it. The benefit is often food” (Rohde, 2005b). Many bacteria, viruses, and fungi are parasitic but usually not studied by parasitologists sensu stricto; they are the domain of microbiologists. Parasites as defined here do not always harm their host; the border between so-called genuine parasites and other symbionts such as commensals is often blurred, and investigators who work on disease aspects tend to emphasis the pathogenic aspects and may not consider non-pathogenic species as truly …

This study determined the effectiveness of rosemary extract on the shelf life of ground beef patties under different retail display conditions. Ground beef patties were produced from an 85%:15% blend (lean:fat). Patties were formed from batches of control or amended with rosemary extract. Patties were individually packaged using overwrap. Groups were assigned into one of two lighting groups (3000K and 3500K). Patties were placed in a simulated retail display for 5 d under continuous lighting and rotated once a day. Lipid oxidation and color samples were taken each day. Relating to lipid oxidation, there was no three-way interaction between display …

Validation Of A Diagnostic Marker For Primocane-Fruiting In Blackberry, Isabella Vaughn, Alexander Silva, Carmen Johns, Lacy Nelson, Margaret Worthington

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Typical blackberries (Rubus subgenus Rubus) have perennial crowns and roots and biennial canes. The first-year canes (primocanes) are usually vegetative, while second-year canes (floricanes) produce fruit. Primocane-fruiting blackberries produce fruit on first-year canes and are desirable to growers because they potentially allow for a longer harvest season in temperate regions and enable production in tropical areas where no natural chill hours are accumulated. The development of molecular markers for desirable traits can potentially increase efficiency in blackberry breeding. However, to date, there are no diagnostic molecular markers for economically important traits in blackberries. Primocane-fruiting is recessively inherited, and tetraploid blackberries …

Temporal, Phenotypic, And Quantitative Characterization Of Thyroid Infiltrating Mononuclear Cells During Development Of Spontaneous Autoimmune Thyroiditis In Obese Strain Chickens, Katelyn M. Clark, Chrysta N. Beck, Gisela F. Erf

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The Obese strain (OS) of chickens spontaneously develops autoimmune thyroiditis (SAT) and is a well-established biomedical model for Hashimoto’s thyroiditis in humans. Both conditions are characterized by the infiltration of thyroid glands with mononuclear immune cells resulting in the destruction of thyroid tissue and impairment of the thyroid’s endocrinological functions. Past studies described immune cell infiltration in thyroids of the OS chickens, but the time-course, cell composition, and relative amounts of the various immune cells infiltrating the thyroids have not been well defined. In this project, frozen and stored thyroid glands that were previously collected at 1, 4, 7, 14, …

Discoverinsects.Com: An Interactive Tool To Introduce Younger Audiences To Entomology, Ian Eldred

Department of Entomology: Distance Master of Science Projects

Early in life, children’s views towards arthropods can be tainted by many things. One major way is through the views held and expressed by those that surround them, especially their caregivers. Tools are needed to reach children during these crucial developmental ages and expose them to all of the wonderful things arthropods do and educate them on how big of a role arthropods play in the lives of every human around the globe. As digital technology in households is becoming more apparent and accessible, new ways to engage these audiences need to be developed and utilized. This creates a unique …

Preventative Weed Management Strategies In Arkansas Tomato Production, Gracie E. Morrison, Matthew Bertucci

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Cost-effective weed suppression is an important consideration for tomato growers. Growers often choose methods which minimize hand labor, as hand weeding can be prohibitively expensive. This project determined economic viability of high tunnel tomatoes treated with several methods of weed control, both organic and chemical. These methods included: 2-week hand weeding, 1-week hand weeding, preemergent herbicide application (plots sprayed with herbicide prior to weed emergence), straw mulch (plots bedded with straw), landscape fabric (plots covered in fabric), and untreated weedy control plots. These six treatments were applied to randomized blocks in a high tunnel. Weeding, planting, and harvesting were all …

Consumers' Perception Of Quality For Ladies' Swimwear Based On Price And Brand, Jennifer Avila, Laurie M. Apple, Lance M. Cheramie, Leigh Southward
