My thesis combines two different perspectives. The first is supply chain management, and the second is volunteering. The inspiration for this topic came from Joy Field's seminar titled "Job Design and Work Allocation for Volunteers in Nonprofit Organizations." My thesis differs from her seminar because I decided to expand her topic to include all types of organizations, not just non-profits. The idea of relating supply chain and volunteering is appealing because I believe getting the most out of each volunteer's experience and those on the receiving end is very important. Additionally, her seminar appealed to me because I have volunteered before and it relates to my major of supply chain management. Volunteer management relates to supply chain management from an operations perspective. A common objective within supply chain operations is maximizing productivity, resources, and value. Mismanaging people can lead to an increased amount of waste in the form of money, time, and resources. That is why it is important to get the most out of the entire experience in order for both the volunteers and the organization to achieve the most benefit. The purpose of this paper is to describe best practices in volunteer management for organizations to consider. I will explore three phases of the volunteer management process: before, during, and after. Additionally, I will provide a personal volunteer experience and assess its effectiveness. My source material consisted of various research articles and journals, and the end result will be an outline of recommendations for organizations to utilize when using volunteers.

The brain continuously monitors speech output to detect potential errors between its sensory prediction and its sensory production (Daliri et al., 2020). When the brain encounters an error, it generates a corrective motor response, usually in the opposite direction, to reduce the effect of the error. Previous studies have shown that the type of auditory error received may impact a participant’s corrective response. In this study, we examined whether participants respond differently to categorical or non-categorical errors. We applied two types of perturbation in real-time by shifting the first formant (F1) and second formant (F2) at three different magnitudes. The vowel /ɛ/ was shifted toward the vowel /æ/ in the categorical perturbation condition. In the non-categorical perturbation condition, the vowel /ɛ/ was shifted to a sound outside of the vowel quadrilateral (increasing both F1 and F2). Our results showed that participants responded to the categorical perturbation while they did not respond to the non-categorical perturbation. Additionally, we found that in the categorical perturbation condition, as the magnitude of the perturbation increased, the magnitude of the response increased. Overall, our results suggest that the brain may respond differently to categorical and non-categorical errors, and the brain is highly attuned to errors in speech.

Cochlear implant (CI) successfully restores hearing sensation to profoundly deaf patients, but its
performance is limited by poor spectral resolution. Acoustic CI simulation has been widely used
in normal-­hearing (NH) listeners to study the effect of spectral resolution on speech perception,
while avoiding patient-­related confounds. It is unclear how speech production may change with
the degree of spectral degradation of auditory feedback as experience by CI users. In this study,
a real-­time sinewave CI simulation was developed to provide NH subjects with auditory
feedback of different spectral resolution (1, 2, 4, and 8 channels). NH subjects were asked to
produce and identify vowels, as well as recognize sentences while listening to the real-­time CI
simulation. The results showed that sentence recognition scores with the real-­time CI simulation
improved with more channels, similar to those with the traditional off-­line CI simulation.
Perception of a vowel continuum “HEAD”-­ “HAD” was near chance with 1, 2, and 4 channels,
and greatly improved with 8 channels and full spectrum. The spectral resolution of auditory
feedback did not significantly affect any acoustic feature of vowel production (e.g., vowel space
area, mean amplitude, mean and variability of fundamental and formant frequencies). There
was no correlation between vowel production and perception. The lack of effect of auditory
feedback spectral resolution on vowel production was likely due to the limited exposure of NH
subjects to CI simulation and the limited frequency ranges covered by the sinewave carriers of
CI simulation. Future studies should investigate the effects of various CI processing parameters
on speech production using a noise-­band CI simulation.

As sustainability has become more prevalent it has become clear that companies have a pressing need to incorporate sustainability into their business. The purpose of this study is to analyze the ways that integrating sustainability can actually provide a financial benefit for a company. Through interviews and extensive research, we will target sustainability initiatives that work for both small and large businesses. This is another key part of our research; addressing the discrepancy in how businesses of different sizes are able to use sustainability, and then finding sustainability initiatives that recognize this discrepancy and are effective for businesses of all sizes.
As sustainability has become more prevalent it has become clear that companies have a pressing need to incorporate sustainability into their business. The purpose of this study is to analyze the ways that integrating sustainability can actually provide a financial benefit for a company. Through interviews and extensive research, we will target sustainability initiatives that work for both small and large businesses. This is another key part of our research; addressing the discrepancy in how businesses of different sizes are able to use sustainability, and then finding sustainability initiatives that recognize this discrepancy and are effective for businesses of all sizes.
Through the interviews of three large corporations (Amazon, Dell, and Lowes), and four small businesses (Exel Shirts, Goode Deals, Desert Dream Ice Cream, and FitzGerald and Sons Contracting) we were able to discover several very effective sustainability initiatives, such as ocean plastics recycling at Dell or packaging advertisements at Amazon. This thesis then discussed what characteristics of these plans are easiest to transfer and implement for businesses of all sizes, classifying the “ideal” sustainability initiative. Possible revenue earners like reusing scrap, and the intangible benefits like saved labor of telecommuting as some of the most significant financial value that sustainability can provide for companies of all sizes.

This thesis explores the likely impacts of climate change on agricultural production globally and in the state of Arizona, and on agricultural supply chains. It shows increases in severe weather, including hotter temperatures and droughts, will have a negative impact on crop production in the state and on global agricultural supply chains. It also shows the effects on the environment caused by our current cradle-to-grave supply chains. As a partial remedy, this thesis explores the benefits of vertical farming systems and shows how they could be of value to the residents of Arizona.

Coffee is one of the most widely consumed beverages in the world, with a staggering 1.4 billion cups of coffee poured a day (Coffee Consumption around the World). One-point six percent of total US GDP is made up by coffee operations and fuels 1.6 million jobs in the United States (The Global Coffee Industry). However, with an increasingly complex political and economic world, along with the threat of climate change, the world’s coffee supply is at risk of total collapse. There are two primary varieties of coffee consumed in the world, Arabica and Robusta coffee. Most coffee producing countries run along the equator and are generally classified as developing economies. The global south is relied upon for coffee production. “Across Mexico and Central America, over 4 million people depend directly on coffee production for their livelihoods” (An Integrated Framework). Coffee production helps boost these economies and support families financially, with many workers having to support dependent individuals.
