The Influences Of Calculus I On Engineering Student Persistence, Amie Baisley Dec 2019

The Influences Of Calculus I On Engineering Student Persistence, Amie Baisley

All Graduate Theses and Dissertations

About half of the students that are declared engineering majors end up leaving engineering within their first two years at the university. This happens following the required math and science courses that these students must take before getting into the technical engineering coursework. There are two systems that students must be a part of at the university to feel comfortable and have the desire to continue on in their degree. These include the academic system and the social system. The experiences engineering students have during their first required math course, Calculus I, is likely not promoting integration into these two ...

The Rise Of Populist Rhetoric And The Mainstreaming Of A Party? Testing The Rhetorical Shifts Between Front National’S Presidents Jean-Marie Le Pen And Marine Le Pen, Muriel C. Mcgregor

All Graduate Theses and Dissertations

Populist movements have been on the rise across Europe and the Americas. In France, the far right-wing party, Le Front National, has experienced recent growth in electoral success. Scholars of the Front National have in part attributed the party’s success to its increased use of populist rhetoric. This thesis examines the populist rhetoric used between the Front National’s past president Jean-Marie Le Pen and current president Marine Le Pen in order to test these scholarly claims. Based on their campaign speeches for the 2002, 2007, 2012, and 2017 French presidential elections, I conducted a quantitative dictionary-based analysis on ...

Development And Validation Of An Agricultural Literacy Instrument Using The National Agricultural Literacy Outcomes, M. Rose Judd-Murray Aug 2019

Development And Validation Of An Agricultural Literacy Instrument Using The National Agricultural Literacy Outcomes, M. Rose Judd-Murray

All Graduate Theses and Dissertations

This study was conducted to develop a standardized agricultural literacy assessment using the National Agricultural Literacy Outcomes (NALOs) as benchmarks. The need for such an assessment was born out of previous research, which found that despite numerous programs dedicated to improving agricultural literacy, many students and adults remain at low or very low levels of literacy. Low literacy levels lead to negative associations with the production and processing of food, clothing, and shelter, as well as misinformed public perceptions and policies. Agricultural literacy researchers recognized that the development of a standardized assessment for post-12th grade, or equivalent, could unify ...


Thylacine Dreams: The Vernacular Resurrection Of An Extinct Marsupial, Daisy M. Ahlstone Aug 2019

Thylacine Dreams: The Vernacular Resurrection Of An Extinct Marsupial, Daisy M. Ahlstone

All Graduate Theses and Dissertations

This thesis explores the folk resurrection of the thylacine through artwork and symbolic interaction. The thylacine, better known as the Tasmanian tiger, is a marsupial that suffered a government-sanctioned massacre leading to its extinction in 1936. The thylacine’s status as a hidden animal has inspired what folklorists call “ostensive practice”; people not only actively seek out the thylacine in the wilderness of Tasmania today and share their sightings online, but they have also incorporated the thylacine as a symbol of hope and perseverance into various forms of folk art.

There have been upwards of five thousand documented sightings of ...


Feature Selection And Analysis For Standard Machine Learning Classification Of Audio Beehive Samples, Chelsi Gupta Aug 2019

Feature Selection And Analysis For Standard Machine Learning Classification Of Audio Beehive Samples, Chelsi Gupta

All Graduate Theses and Dissertations

The beekeepers need to inspect their hives regularly in order to protect them from various stressors. Manual inspection of hives require a lot of time and effort. Hence, many researchers have started using electronic beehive monitoring (EBM) systems to collect critical information from beehives, so as to alert the beekeepers of possible threats to the hive. EBM collects information by applying multiple sensors into the hive. The sensors collect information in the form of video, audio or temperature data from the hives.

This thesis involves the automatic classification of audio samples from a beehive into bee buzzing, cricket chirping and ...

Social Media Use During Crisis Events: A Mixed-Method Analysis Of Information Sources And Their Trustworthiness, Apoorva Chauhan

All Graduate Theses and Dissertations

This dissertation consists of three studies that examine online communications during crisis events. The first study identified and examined the information sources that provided official information online during the 2014 Carlton Complex Wildfire. Specifically, after the wildfire, a set of webpages and social media accounts were discovered that were named after the wildfire—called Crisis Named Resources (or CNRs). CNRs shared the highest percentage of wildfire-relevant information. Because CNRs are named after a crisis event, they are easier to find and appear to be dedicated and/or official sources around an event. They can, however, be created and deleted in ...


Epigenetic Reprogramming, Apoptosis, And Developmental Competence In Cloned Embryos, Laura A. Moley Aug 2019

Epigenetic Reprogramming, Apoptosis, And Developmental Competence In Cloned Embryos, Laura A. Moley

All Graduate Theses and Dissertations

Cloning through somatic cell nuclear transfer (SCNT) remains highly inefficient twenty years after the first demonstration of the technology with the birth of Dolly. By increasing efficiency by selecting the embryos early in development that are most likely to succeed following transfer into a surrogate mother, the technology could be more routinely utilized to enhance animal agriculture production. SCNT is believed to be highly inefficient as a result of incorrect DNA methylation and gene expression that are accumulated because of the SCNT technique. We proposed the use of a non-toxic, non-invasive detector of cell death, to quantitatively assess embryo competency ...

Synthesis And Biological Studies Of Amphiphilic Compounds Derived From Saccharides And Aminoglycosides, Madher N. Alfindee

All Graduate Theses and Dissertations

Adjacent cells communicate through gap junctions (GJs). These GJs are formed by head to head docking of two hemichannels (HCs) from two adjacent cells. HCs are connexin hexamer proteins. Connexin mutation is the most frequent cause of childhood hearing loss. This hearing impairment affects 2 in every 2000 children. Inhibition of the HCs might be the key factor to treat such disorders. A library of amphiphilic kanamycins was synthesized to be tested as HC inhibitors. These compounds showed excellent inhibition activity in comparison with the parent compound (kanamycin A) with less toxicity.

A library of monosaccharide esters with varying carbon ...

All Graduate Theses and Dissertations

After the English-led invasion of Ireland, between 1169 and 1172, the country was run by Anglo-Irish lords—English and Welsh men gifted with Irish land and titles for their service to the English King. Of these families, the Butlers were one of the three most powerful in the country. The 3rd and 4th Earls of Ormond, both named James Butler, each held the highest title in Ireland, Lord Lieutenant, multiple times as well as being successful military leaders. Add to this a large income from all the wine revenues of the country, and the Butlers were a force ...


The Thermal And Physical Properties Of Beef From Three Usda-Quality Grades Cooked To Multiple Degrees Of Doneness, Jessica Mcclellan Hadfield Aug 2019

The Thermal And Physical Properties Of Beef From Three Usda-Quality Grades Cooked To Multiple Degrees Of Doneness, Jessica Mcclellan Hadfield

All Graduate Theses and Dissertations

The objective of this study was to determine the influence of quality grade (QG) and degree-of-doneness (DOD) on thermophysical properties of beef strip steaks. The “Prime” eating experience must be marketed to compete with cheaper protein sources, and so palatability is a major concern with beef products. Thermal and physical properties help shed light on the impacts various components have on beef palatability, mainly tenderness and juiciness. Warner-Bratzler shear force (WBSF) and the textural property of springiness are both influenced by a combination of QG and DOD. This is also true for viscoelasticity and the degradation of myosin and sarcoplasmic ...

The five major emerging themes from this study are Catalysts for Recovery, Foundation ...


Investigation Of Graphene Interconnections For Multifunctional Reconfigurable Antenna Beam Steering, Joshua R. Perkins Aug 2019

Investigation Of Graphene Interconnections For Multifunctional Reconfigurable Antenna Beam Steering, Joshua R. Perkins

All Graduate Theses and Dissertations

In high frequency, high-performance wireless communications, direct line of sight antennas are common. The issue with the line of sight antennas is the need to redirect the physical antenna to achieve the best possible reception. Classical redirections are done by mechanical movements: hand tuning and motors. Our multi-functional re-configurable antenna (MRA) concept allows for electrical and non-mechanical antenna reorientation. This work investigates two important concepts in the development and enhancement of future MRA devices: special, non-interfering, control signal circuitry and nano-sized switching devices that are controlled by the special circuitry. The investigation was conducted with the use of commercially available ...
