Description
Human activities around the world are threatening scores of wildlife species, pushing them closer to extinction. In order to address what many conservationists view as a global biodiversity crisis, it is vital that more people are inspired to care about wild animals and motivated to act in ways that help protect them. The up-close experiences and personal connections that people form with wild animals in zoos accredited by the Association of Zoos and Aquariums (AZA) or the World Association of Zoos and Aquariums (WAZA) can help achieve this. However, it is not very well understood how different types of encounters within these zoos may inspire conservation mindedness and pro-environmental behaviors. During this thesis project, surveys were conducted at the AZA-accredited Arizona Center for Nature Conservation/Phoenix Zoo to understand how interactive, hands-on animal experiences within zoos differ from passively viewing zoo animals when it comes to inspiring people to care about conservation. The Phoenix Zoo is home to two different species of giraffes, and guests can view them from the front of the Savanna Exhibit. Guests can also participate in the Giraffe Encounter, which is a much more interactive, hands-on experience. After surveying guests at both locations, the results showed that fewer people at the Giraffe Encounter responded that they often engage in pro-environmental behaviors. This may indicate that the people who participated in the Giraffe Encounter came to the zoo more for recreation and entertainment than to learn about wildlife. Despite this, more people learned something new about nature or conservation at the Giraffe Encounter than they did at the Savanna Exhibit. On average, guests also felt that the Giraffe Encounter motivated them to learn more about how to help animals in the wild than the Savanna Exhibit did. Overall, there is a strong correlation between having an interactive, hands-on experience with a zoo animal and caring more about wildlife conservation. However, more research still needs to be done in order to conclusively provide evidence for causation.

Description
Cancer is a disease in which abnormal cells divide uncontrollably and destroy body tissue, and currently plagues today’s world. Carcinomas are cancers derived from epithelial cells and include breast and prostate cancer. Breast cancer is a type of carcinoma that forms in breast tissue cells. The tumor cells can be further categorized after testing the cells for the presence of certain molecules. Hormone receptor positive breast cancer includes the tumor cells with receptors that respond to the steroid hormones, estrogen and progesterone, or the peptide hormone, HER2. These forms of cancer respond well to chemotherapy and endocrine therapy. On the other hand, triple negative breast cancer (TNBC) is characterized by the lack of hormone receptor expression and tends to have a worse prognosis in women. Prostate cancer forms in the cells of the prostate gland and has been attributed to mutations in androgen receptor ligand specificity. In a subset of triple negative breast cancer, genetic expression profiling has found a luminal androgen receptor that is dependent on androgen signaling. TNBC has also been found to respond well to enzalutamide, a an androgen receptor inhibitor. As the gene of the androgen receptor, AR, is located on the X chromosome and expressed in a variety of tissues, the responsiveness of TNBC to androgen receptor inhibition could be due to the differential usage of isoforms - different gene mRNA transcripts that produce different proteins. Thus, this study analyzed differential gene expression and differential isoform usage between TNBC cancers – that do and do not express the androgen receptor – and prostate cancer in order to better understand the underlying mechanism behind the effectiveness of androgen receptor inhibition in TNBC. Through the analysis of differential gene expression between the TNBC AR+ and AR- conditions, it was found that seven genes are significantly differentially expressed between the two types of tissues. Genes of significance are AR and EN1, which was found to be a potential prognostic marker in a subtype of TNBC. While some genes are differentially expressed between the TNBC AR+ and AR- tissues, the differences in isoform expression between the two tissues do not reflect the difference in gene expression. We discovered 11 genes that exhibited significant isoform switching between AR+ and AR- TNBC and have been found to contribute to cancer characteristics. The genes CLIC1 and RGS5 have been found to help the rapid, uncontrolled growth of cancer cells. HSD11B2, IRAK1, and COL1Al have been found to contribute to general cancer characteristics and metastasis in breast cancer. PSMA7 has been found to play a role in androgen receptor activation. Finally, SIDT1 and GLYATL1 are both associated with breast and prostate cancers. Overall, through the analysis of differential isoform usage between AR+ and AR- samples, we uncovered differences that were not detected by a gene level differential expression analysis. Thus, future work will focus on analyzing differential gene and isoform expression across all types of breast cancer and prostate cancer to better understand the responsiveness of TNBC to androgen receptor inhibition.

Description
Over the past six years, China has embarked on an international economic initiative titled, “The Belt and Road Initiative” in which it finances and constructs multi-billion-dollar infrastructure development projects around the world. Aimed at building out energy and transportation infrastructure, these projects are being undertaken in approximately 68 countries. So far, China has pledged $1 trillion to the initiative, 95% of which is has come from public sources . However, it is projected that, in order to maintain its current growth, Developing Asia will require an additional $26 trillion in investment by 2030 .
The hundreds of projects have been grouped into six maritime and land-based economic corridors that retrace many of the original routes of the Silk Road. Of these corridors, the China-Pakistan Economic Corridor (CPEC) has proven to be one of the most important in China’s quest for Asian economic integration. The CPEC is the BRI’s first major economic corridor and one of the largest, receiving approximately $39 billion in investments to date.
Despite the thousands of articles and research papers that have been written on the topic, there are very few resources that provide a more comprehensive view of the Belt and Road Initiative. Consistent information on BRI projects is difficult to find, as both China and its debtors have been withholding many of the details regarding construction progress and lending activity. As a result, this thesis attempts to reconcile the simultaneous surplus of research with the shortage of conclusive information by framing its analysis in the form of a question about the BRI’s likelihood of success.
This thesis explores the history of the Silk Road, the progress of the Belt and Road Initiative, and the project’s global implications. In order to determine the BRI’s likelihood of success, this thesis identifies the China-Pakistan Economic Corridor (CPEC) as the economic corridor most likely to succeed of the six. It then analyzes the CPEC, determining that, despite the fact that it is the economic corridor most likely to succeed, it likely will not. It then builds upon this to conclude that the BRI, too, is unlikely to succeed.
In addition, this thesis critiques many of the expansionary policies, loose lending practices, and near-term decisions made by Chinese leadership by arguing that the BRI is an initiative for the benefit of China and not its debtors.

Description
This is a report on an experiment that examines if the principles of multimedia learning outlined in Richard E. Mayer’s journal article, “Using multimedia for e-learning”, located in the Journal of Computer Assisted Learning would apply to haptic feedback used for haptic robotic operation. This was tested by developing and using a haptic robotic manipulator known as the Haptic Testbed (HTB). The HTB is a manipulator designed to emulate human hand movement for haptic testing purposes and features an index finger and thumb for the right hand. Control is conducted through a Leap Motion Controller, a visual sensor that uses infrared lights and cameras to gather various data about hands it can see. The goal of the experiment was to have test subjects complete a task where they shifted objects along a circuit of positions where they were measured on time to complete the circuit as well as accuracy in reaching the individual points. Analysis of subject responses to surveys as well as performance during the experiment showed haptic feedback during training improving initial performance of individuals as well as lowering mental effort and mental demand during said training. The findings of this experiment showed support for the hypothesis that Mayer’s principles do apply to haptic feedback in training for haptic robotic manipulation. One of the implications of this experiment would be the possibility for haptics and tactile senses to be an applicable sense for Mayer’s principles of multimedia learning as most of the current work in the field is mostly focused on visual or auditory senses. If the results of the experiment were replicated in a future experiment it would provide support to the hypothesis that the principles of multimedia learning can be utilized to improve the training of haptic robotic operation.

Description
Dissolved organic matter (DOM) can have numerous effects on the water chemistry and the biological life within an aquatic system with its wide variety of chemical structures and properties. The composition of the dissolved carbon can be estimated by utilizing the fluorescent properties of some DOM such as aromatic amino acids and humic material. This experiment was used to observe how organic matter could influence hydrothermal systems, such as Sylvan Springs in Yellowstone National Park, USA. Using optical density at 600 nm (OD 600), excitation-emission matrix spectra (EEMS), and Illumina sequencing methods (16S rRNA gene sequencing), changes in dissolved organic matter (DOM) were observed based on long term incubation at 84ºC and microbial influence. Four media conditions were tested over a two-month duration to assess these changes: inoculated pine needle media, uninoculated pine needle media, inoculated yeast extract media, and uninoculated yeast extract media. The inoculated samples contained microbes from a fluid and sediment sample of Sylvan Spring collected July 23, 2018. Absorbance indicated that media containing pine needle broth poorly support life, whereas media containing yeast extract revealed a positive increase in growth. Excitation-Emission Matrix Spectra of the all media conditions indicated changes in DOM composition throughout the trial. There were limited differences between the inoculated and uninoculated samples suggesting that the DOM composition change in this study was dominated by the two-month incubation at 84ºC more than biotic processes. Sequencing performed on a sediment sample collected from Sylvan Spring indicated five main order of prokaryotic phyla: Aquificales, Desulfurococcales, Thermoproteales, Thermodesulfobacteriales, and Crenarchaeota. These organisms are not regarded as heterotrophic microbes, so the lack of significant biotic changes in DOM could be a result of these microorganisms not being able to utilize these enrichments as their main metabolic energy supply.

Imagine you and your significant other are relaxing at home watching your favorite Netflix show. You are embraced equally between the arm of your couch and the arm of your significant other right in front of your television. While the living room is small, you both work long days to be in this very position, some would call this your natural environment. In your brief moment of bliss as you sink further into your couch, you have a shiver creep down your spine as you are pressed between your two loves. As you are disgruntled from either the approaching winter or your requirement to simply move, you reach up to turn your ceiling fan off. When you attempt to recover what comfort you peeled yourself out of, you discover a greater inconvenience as the fan blades begin to slide to a stop. Dust, grime and the results of dirty air are caked on the fan blades. You think of climbing onto your coffee table and wiping the blades as all the dust falls on you and your living room. With a sigh, you surmise to deal with the eye sore another day and hope you find the motivation to deal with it another day.

Description
In recent years, the Maine lobster industry, researchers, and policy makers have attempted to come together to set new regulations into place that will help slow the decline of right whale populations off the North Atlantic coast. Like many species, right whales were once abundant in the Atlantic before commercial whaling practices decimated populations to near extinction by the 1900’s (Fujiwara et al., 2001). Today’s populations total to approximately 450 individuals worldwide and continue to decline despite conservation efforts (Pace et al., 2017). Though commercial whaling no longer poses a threat to right whales, there are other factors that have proven to be detrimental to their survival. In particular, ship strikes and entanglement in fishing rope are the main causes for continued population decline (Knowlton et al., 2012).
One may ask, how is all of this connected specifically to the Maine lobster industry? It has been determined that approximately 80% of right whales currently have scars along their bodies as a result of being entangled in fishing rope. More specifically, the rope that right whales are becoming entangled in is the vertical line used by lobstermen that connects the lobster trap lying on the seafloor to a buoy at the surface. Not only can this entanglement lead to the drowning of individuals, but also a decreased birth rate among females due to stress should they successfully free themselves (Knowlton et al., 2012).
In an attempt to decrease entanglement rates and bring the decline in right whale populations to a halt, the state of Maine has been in the process of creating and implementing new policies, many of which will have an impact on the lobster industry. Regulations that have been considered include weakened vertical lines, modified gear marking, a change in rope color, reduction in traps, or even the introduction of new ropeless technology.
What perceptions do lobstermen in Maine have regarding the conservation of right whales and the possible regulations that could be put into place? To address this question, I posted a Google Forms survey link on a local Maine fishermen’s Facebook page in late December 2018 that remained open until the end of February 2019. The five-minute survey was to be completed on a voluntary basis to gather a convenient sample from the 15,000 members on the group page, of which not all were lobstermen. There was a total of 39 participants. The survey asked about opinions regarding a series of possible regulations that could possibly impact the lobster industry, should they be implemented. Additionally, the survey provided space for lobstermen to explain how past regulations had impacted them personally, as well as space for recommendations they thought would help conserve right whale populations while simultaneously creating little negative impact on the lobster industry.

Description
The Precariat is a socioeconomic class that live extremely precarious lives due to job insecurity, financial instability, and lack of ability to prepare for the future. This class falls through the cracks of the present system; a system that is failing to identify and support the true struggling working class. Many of these workers just barely miss the financial cut off for government assistance programs (e.g LIHEAP and SNAP) or may be unaware of all the resources available to them. A citizen of the Precariat can possess a variety of characteristics. This class is thought to be divided into three factions with unique dimensions. There is a collective mentality and pressure to accept unstable labor; thus, why there is no occupational or demographic identity of the Precariat. The three factions can be titled as follows: atavists, progressives, and nostalgics. These titles reflect the differentiating traits and attitudes of each faction.

Description
Lower termites are classified as termites that require a symbiotic relationship with their hindgut community of single-celled protozoa in order to gather nutrients to survive. The class Spirotrichonymphea is one of the six classes of protists that make up the Phylum Parabasalia. Within the class Spirotrichonymphea, there are 3 families and 11 genera. In this study, the Spirotrichonympha, Spironympha, and Microjoenia genera (family Spirotrichonymphidae), Holomastigotes genus (family Holomastigotidae), along with a new genus Brugerollea were targeted for molecular analysis. Protist cells were collected from Reticulitermes tibialis (Rhinotermitidae), Hodotermopsis sjostedti (Archotermopsidae), and Paraneotermes simplicornis (Kalotermidiae). Most molecular phylogenetic studies of termite-associated protists have used the 18S rRNA gene, however, there have been some ambiguities in the phylogeny of this gene. EF1-α, also known as EF1A, is a protein whose sequence can additionally be used to study the evolution of protists. EF1-α gene sequences were obtained from isolated protist cells by reverse transcription PCR (RT-PCR). Additionally, the 18S rRNA gene was amplified to confirm the isolated cells’ identity and compare the two phylogenetic methods, to see which would better resolve phylogenetic ambiguities. Sequences were compiled into an alignment for each target gene, and then a maximum likelihood tree was created for each using RAxML. Results from both trees supports the monophyly of Spirotrichonymphea and the polyphyly of genus Spirotrichonympha. However, neither gene fully resolves the phylogeny of Spirotrichonymphea.

Description
The goal of this study was to examine whether there is any effect of phonotactic probability during the early phases of novel word recognition. In order to determine this, I performed two experiments. In Experiment 1, 33 adult monolingual English speakers learned 24 novel word-object pairings, half of which were high English phonotactic probability words and the other half were low English phonotactic probability words. I additionally included three conditions that varied the amount of exposures to each novel word-object pairing (i.e. One Exposure Condition, Two Exposures Conditions, and Five Exposures Condition). Experiment 2 was designed to clarify results found in Experiment 1, with improved randomization and fewer conditions (i.e. One Exposure Condition and Five Exposures Condition). The findings from both experiments were statistically significant in accuracy for Training condition, but not statistically significant for phonotactic probability nor for an interaction between phonotactic probability and Training condition. Although participants demonstrated learning across conditions there is no indication of a relationship between high and low phonotactic probability and novel word recognition. Collectively, these findings suggest that future studies will be necessary to determine if there is indeed an effect of phonotactic probability on early novel word recognition.
