The Need For A Chainsaw Safety Training Program For Female Forest Landowners, Patrick Hiesl, Janet Steele, Susan T. Guynn

Journal of Extension

Female forest landowners (FFLO) are increasing in numbers but have been marginalized in technical training programs in the past. We conducted chainsaw safety training programs geared towards FFLO and compared program evaluation results with results from male-dominated chainsaw training workshops. FFLO are limited in their technical knowledge at the beginning of a workshop, are more likely to own different types of chainsaws than male participants, and generally liked having a women-only workshop. The takeaway is that FFLO strive in a women-only environment and that more women-focused extension training programs are needed to provide with a safe and inclusive learning environment.

Offering Collegiate Livestock Judging As A Student Organization, Maryfrances Miller, Don W. Edgar, Lyle Logemann

Journal of Extension

Resource constraints have lowered the number of collegiate livestock judging teams, dropping the number of opportunities for collegiate judging, even though interest among students remains high. These opportunities can be provided for less expense through student-led extracurricular organizations. This approach increases the student initiative required, but also provides an increased opportunity for developing and demonstrating leadership skills.

Using Multimedia To Help Agricultural Producers Communicate With Consumers About Gmos, Stacey F. Stearns, Jennifer E. Cushman, Joseph A. Bonelli, Bonnie E. Burr

Journal of Extension

Genetically modified organisms (GMOs) and their uses are often misunderstood. Consumers are regularly unsure what GMOs are, or if they are safe for consumption and the environment. Contradictory and sometimes inaccurate information is available from numerous sources, and challenges consumers and others to separate the facts from sensationalized stories. Agricultural producers often communicate with consumers, neighbors, and members of the general public; however, they do not have information to share about GMOs. Multimedia resources can provide agricultural producers with science-based information to share with consumers. Agricultural communicators and Extension educators can create science-based multimedia resources to bridge the communication gap.

Consumer-Focused Meat Science Extension Program Increase Consumer Confidence And Knowledge Of Meat Selection And Preparation, Stacy Zuelly, Yufei Guo, Melinda Dennis, Emily Ford, Melissa Davis

Journal of Extension

Science-based, meat science education is often limited outside of universities, creating possibilities to develop Extension activities to educate and impower consumers in principles of meat science.

Structural And Blood Co-Factor Binding Studies Of A Red Algal Sulfated Galactan, Anderson R. Dewitt

Honors Theses

The red alga Botryocladia occidentalis presents three distinct fractions of sulfated polysaccharides. The elucidation of structures of various B. occidentalis fractions has been explored in prior research. In this study, the first fraction with the least sulfation underwent NMR structure elucidation. Additionally, this sulfated polysaccharide underwent analysis following chemical modifications. Findings have unveiled the presence of both 4-linked α- and 3-linked β-galactose units with the following chemical characteristics: over half of the total galactose units are unsulfated, the α-units are primarily 3,6-anhydrogalactose units either 2-O-methylated or 2-O-sulfated, and the β-galactose units can be 4-O-sulfated or 2,4-O-disulfated. Results from SPR-based assays …

Unraveling The Paradox Of The 'Great Speciators': Evolutionary Dynamics Of A Geographic Radiation Of Island Kingfishers (Todiramphus), Jenna Merle Mccullough

Biology ETDs

The paradox of the ‘Great Speciators’ describes a biogeographic pattern in which geographically widespread lineages have strong overwater dispersal capabilities, yet exhibit genetic and phenotypic divergence between islands, suggesting limited dispersal and cessation of gene flow. In my dissertation, I leveraged whole genomes and two comprehensive trait datasets of dispersal ability and plumage coloration of all described diversity within Todiramphus kingfishers, a rapid radiation of largely island endemic ‘Great Speciators.’ Chapter 1 reveals that whole genome datasets do not outright solve the evolutionary relationships of this clade and that widespread incomplete lineage sorting (ILS) and gene flow are sources of …

The Contributions Of Philosophical Anthropology To Healthcare Ethics, Bura Koroba

Electronic Theses and Dissertations

The first principles of bioethics, autonomy, beneficence, nonmaleficence, and justice have contributed immensely to healthcare ethics. The procedural approach streamlines the decision-making process, protects vulnerable subjects, and fosters stability and trust in the patient-caregiver relationship. Yet, the principles are demonstrably insufficient, riddled with limitations and loopholes that could stand in the way of care.[i] Several recommendations have been proffered to remedy the deficiencies. Value ethics, for instance, has been touted as a proficient addendum to the foundations established by the principles. Still, these have not sufficiently addressed all arising issues in bioethics. Besides the challenges encountered in decision-making, opposing …

However, scholars have raised concerns about just and rational procurement and transplantation in a global shortage. This dissertation addresses normative approaches for organ/tissue procurement, allocation and transplantation to highlight the related pivotal ethical issues. It defends normative approaches such as queuing and nudging, and upholds their universal obligatoriness. It provides illumination about the demands of an effective solution to who shall receive or give organs when not all can. The introductory chapter employs common morality as a principal source of …

Are Impacts Of The Invasive Alien Plant Crassula Helmsii Mediated By Detritus? A Litter Experiment In A Temperate Pond, Samuel J.L. Tasker, Andrew Foggo, David T. Bilton

School of Biological and Marine Sciences

Because of the high growth rates often achieved by invasive alien macrophytes, their establishment in recipient ecosystems may alter the abundance and composition of litter entering detrital pathways, representing a significant—but often overlooked—ecological effect of these invasions. Crassula helmsii (Kirk) Cockayne (New Zealand pygmyweed) is an invasive alien macrophyte, notorious for its profuse growth in invaded waterbodies. C. helmsii is perennial and often forms dense stands, producing abundant detritus. To investigate whether some of C. helmsii’s impacts are mediated by this detritus, we conducted an 85-day litterbag experiment comparing decomposition of C. helmsii with that of Callitriche stagnalis Scop. (water-starwort), …

Water availability is presently under risk owing to the increased discharge of pollutants from both industrial and residential properties. A distinct category of pollutants known as "emerging contaminants" (ECs), whose hazards were either unknown before they were noticed, e.g., antibiotics, dyes, PFAS, etc. Most of the ECs are unregulated and pose a threat to aquatic and human life at even low doses. Our water treatment facilities are not designed to efficiently eliminate these toxic substances. Therefore, we need an economical tertiary treatment approach. Adsorptionis a sustainable, cost effective and simple technique, making it a viable technique for pollutants elimination on …

Motivations For Habitat Management Of Private Lands In The Southeastern United States: Implications For At-Risk Species, Caleb Michael Blake

Theses and Dissertations

Private lands play a crucial role in protecting at-risk species in the Southeast, and finding ways to increase landowner participation in conservation efforts is essential. I surveyed non-industrial private forest owners in Mississippi to assess how their motivations for land management relates to their willingness to manage for at-risk species. I also assessed if landowners who hunt are more willing to manage for at-risk species. Results showed that landowners are motivated by a sense of stewardship for the land, but there is a lack of awareness about at-risk species. Although the effect size was minimal, there is a significant relationship …
