The Psychology Of Science Denialism And Lessons For Public Health Authorities, Brenna Moreno, Molly J. Walker Wilson

All Faculty Scholarship

As it wreaked tragedy on the world, the outbreak of COVID-19 helped expose a pandemic of a different kind, one steeped in distrust and contrarianism. This movement, termed science denialism, has been lurking and undermining public health efforts for decades. Specifically, it is “the employment of rhetorical arguments to give the appearance of legitimate debate where there is none, an approach that has the ultimate goal of rejecting a proposition on which a scientific consensus exists.” Unlike skepticism, which is “doubt as to the truth of something” and works to progress both science and society, denialism is characterized by individuals’ …

Women Pursuing An Agricultural Systems Technology Degree, Tanya Milam

Murray State Theses and Dissertations

Abstract

This phenomenological research study examined the factors influencing women to pursue an Agricultural Systems Technology (AST) degree and their self-efficacy in that field of study. Two research questions guided this study and data was analyzed from interviewing women enrolled in an Agricultural Systems Technology (AST) program at a mid-western university. The resulting four categories of Agricultural Experiences, Aptitude, Support, and Motivation were broken down into themes. The results were also applied to the theoretical framework of self-efficacy associated with career choice theories. Limitations of scope and generalizability indicate that further investigation of this topic is highly recommended.

Bayesian Structural Time Series Methods For Modeling Cattle Body Temperature In Heat-Stressed Animals, Lacey Quandt

Murray State Theses and Dissertations

Climate change has had devastating effects globally, most commonly talked about during natural disasters and rising temperatures. Notably, the climate concern is turning towards agriculture and livestock. With rising temperatures, the prolonged amount of heat stress put on animals, specifically cattle, is becoming more apparent. Heat stress has been linked to a reduction in cattle growing and fattening, feed intake, productivity, reproduction, and fertility; increased heart rates and respiration; changes in behavior; and mortality in severe cases. There are abatement strategies put in place to lower heat stress in cattle, such as improvements in shading and cooling, nutritional management, and …

A Single-Molecule Method For Measuring Fluorophore Labeling Yields For The Study Of Membrane Protein Oligomerization In Membranes, Melanie Ernst, Tugba N. Ozturk, Janice L. Robertson

2020-Current year OA Pubs

Membrane proteins are often observed as higher-order oligomers, and in some cases in multiple stoichiometric forms, raising the question of whether dynamic oligomerization can be linked to modulation of function. To better understand this potential regulatory mechanism, there is an ongoing effort to quantify equilibrium reactions of membrane protein oligomerization directly in membranes. Single-molecule photobleaching analysis is particularly useful for this as it provides a binary readout of fluorophores attached to protein subunits at dilute conditions. However, any quantification of stoichiometry also critically requires knowing the probability that a subunit is fluorescently labeled. Since labeling uncertainty is often unavoidable, we …
