Italian Ryegrass (Lolium Perenne L. Ssp. Multiflorum) Control In Mississippi Corn (Zea Mays L.) Production, Michael Todd Wesley Jr Dec 2019

Italian Ryegrass (Lolium Perenne L. Ssp. Multiflorum) Control In Mississippi Corn (Zea Mays L.) Production, Michael Todd Wesley Jr

Theses and Dissertations

Studies were conducted in the field and in containers in Mississippi from 2017-2019 to optimize Italian ryegrass control in corn production. Most fall-applied residual herbicides provided ≥ 90% Italian ryegrass control 56 days after treatment (DAT) in both field and container experiments. Oxyflurofen provided 95% Italian ryegrass control 28 DAT but only 81% control 56 DAT in field plots. S-metolachlor plus atrazine followed by paraquat produced the highest return on investment for both site-years. The timing of removal study indicates the optimum time to remove Italian ryegrass relative to corn planting is approximately three to four weeks prior to planting. …

Family Firm Selection: A Relational Perspective, William Elliot Tabor Dec 2019

Family Firm Selection: A Relational Perspective, William Elliot Tabor

Theses and Dissertations

This study focuses on the hiring of nonfamily employees in family firms. Research to date has emphasized the challenges family firms confront in attracting and selecting quality nonfamily human capital. This literature has emphasized the limitations these firms face due to the information asymmetries common to the hiring process. However, this research has not considered the advantages available to family firms through their social network. Drawing on agency theory, I hypothesize that owner referral utilization mediates the relationship between family essence and firm performance because their use lessens the agency conflicts between owners and nonfamily members. Utilizing a sample of …

How The Dogface Got Its Color: How Genetics And The Environment Influence Color Variation Within And Between Species In The Zerene Butterfly, Jennifer Fenner Dec 2019

How The Dogface Got Its Color: How Genetics And The Environment Influence Color Variation Within And Between Species In The Zerene Butterfly, Jennifer Fenner

Theses and Dissertations

A fundamental question in biology is: How is variation generated? At a basic level, the vast amount of variation and biodiversity is generated through a combination of genetic and environmental processes. Traditionally these processes were treated independently, but recently fields such as evolutionary development have worked to unify our understanding of these mechanisms and to investigate how these processes interact with each other to generate variation. Developmental plasticity provides a fantastic framework for studying how genetic and environmental (GxE) interactions shape and maintain natural variation. Butterflies and their wing color patterns have long been model systems for plasticity. This dissertation …

Service And Empathy: A Comparison Study Of Intercultural Experiences Among Students At Mississippi College, Victoria Rose Marshall

Theses and Dissertations

Service to the community is a key element in mission statements of public and private universities. In the 21st century, higher education shifted by establishing community engagement offices and encouraging student community service through service-learning. Previous literature indicated that experiential learning increased ethnocultural empathy and volunteerism among college students. This study compares two experiential learning programs’ influence on the ethnocultural empathy development among college students at Mississippi College, a private, religious-affiliated university to explore how this empathy increases community service. 38 students were asked to complete the Scale of Ethnocultural Empathy (Wang et al. 2003) and were interviewed about their …

Problem Solving And Suicide: A First Look, Caitlin E. Titus Dec 2019

Problem Solving And Suicide: A First Look, Caitlin E. Titus

Theses and Dissertations

Suicide is the 10th leading cause of death in the United States, with rates increasing over the past several decades. This study examined whether problem-solving performance differs in those with no suicide ideation or attempts compared to those with only suicide ideation and with those with a history of attempts. Results demonstrated that when accounting for depression, problem-solving accuracy was positively predictive for the suicidal ideation group. Furthermore, the suicidal ideation group solved more problems on average than both those with no history of suicidal thoughts and behaviors and the suicide attempt group. The current study was somewhat underpowered and …

Impact Of Refrigerated Storage On The Dissipation Of Woody Broiler Breast Meat, Michael Byron Dec 2019

Impact Of Refrigerated Storage On The Dissipation Of Woody Broiler Breast Meat, Michael Byron

Theses and Dissertations

Chicken breast samples, (n=90; n=30 normal, n=30 moderate woody breast (WB), n=30 severe WB) were collected from a commercial processing plant on 5 separate occasions. After 5 days of storage at 2-4 ºC, 84% of severe WB fillets dissipated to moderate WB, which was greater (P<0.05) than all other storage times. In comparison, 40-52% of the moderate WB fillets dissipated to slight WB or normal breasts after 3 to 5 days of storage. Shear force was greater (P<0.05) for normal breast meat than moderate and severe WB meat on day 0. After 2, 3, 4, and 5 days of storage the upper position (cranial part) of severe WB had greater shear force than normal fillets (P<0.05). Therefore, the dissipation that occurred in woody breast meat over refrigerated storage was apparent through palpation but did not result in improved texture in the cranial portion of the breast, based on shear force results.

Animal, Dairy, and Veterinary Science Faculty Publications

Exposure of lupus-prone female NZBWF1 mice to respirable crystalline silica (cSiO2), a known human autoimmune trigger, initiates loss of tolerance, rapid progression of autoimmunity, and early onset of glomerulonephritis. We have previously demonstrated that dietary supplementation with the ω-3 polyunsaturated fatty acid docosahexaenoic acid (DHA) suppresses autoimmune pathogenesis and nephritis in this unique model of lupus flaring. In this report, we utilized tissues from prior studies to test the hypothesis that DHA consumption interferes with upregulation of critical genes associated with cSiO2-triggered murine lupus. A NanoString nCounter platform targeting 770 immune-related genes was used to assess …

The Morphology, Pigmentation, And Development Of Structural Coloration In Vanessa Cardui (Lepidoptera: Nymphalidae), Emily A. Shelby Dec 2019

The Morphology, Pigmentation, And Development Of Structural Coloration In Vanessa Cardui (Lepidoptera: Nymphalidae), Emily A. Shelby

Theses and Dissertations

Butterfly wing color patterns are produced by the placement of monochromatic scales that have specific colors due to pigmentation, nanostructures, or a combination of both. Structural coloration results from the interference of light from the architecture of the nanostructures. Structural coloration in butterfly scales has been studied optically, but little is known about the mechanisms used to create these scales compared to scales without structural coloration. Light, scanning, and transmission electron microscopy were used to determine underlying morphological, pigmentation, and developmental differences between blue (i.e., structural) and black (i.e., nonstructural) wing scales of Vanessa cardui. Differences in scale size, pigmentation, …

Reduced Herbicide Antagonism Through Novel Spray Application Techniques, Luke H. Merritt Dec 2019

Reduced Herbicide Antagonism Through Novel Spray Application Techniques, Luke H. Merritt

Theses and Dissertations

Field studies were conducted to test three application methods for applying antagonistic herbicide combinations: 1) tank mix (TMX), 2) mix-in-line (MIL), and 3) separate boom (SPB). Sethoxydim applied with bentazon, glyphosate applied with dicamba or 2,4-D, and clethodim applied with dicamba or 2,4-D had higher efficacy when applied using the SPB method. Antagonism of all the herbicide combinations above was observed when applied using the TMX and MIL methods. In some cases, antagonism was avoided when using the SPB method. Three application methods tested in greenhouse studies were 1) TMX, 2) synthetic auxin applied first (AAF), and 3) synthetic auxin …

Fraze Mowing For Overseeding Establishment And Removal Of Perennial Ryegrass, Matthew Carpenter Dec 2019

Fraze Mowing For Overseeding Establishment And Removal Of Perennial Ryegrass, Matthew Carpenter

Theses and Dissertations

Fraze mowing offers a new tool used in both overseeding establishment and removal of perennial ryegrass (Lolium perenne L.). Research objectives were to determine the most effective timing of fraze mowing in overseeding establishment and removal, as well as to compare fraze mowing to other establishment and removal methods. Fall overseeding studies suggest that fraze mowing and scalping in mid-October provides the fastest establishment of ryegrass. However, by mid-March all treatments led to visually similar results. When evaluating removal timings, fraze mowing performed in early- and late-May led to faster visual bermudagrass recovery than March and April timings. Early-season application …
