Description
Students in an online course can face diminished incentives to exert effort and focus without the structure of instructor-paced material. To introduce new motivation to spend more time with course material, this paper examines the use of A/B split test content experiments. One group of students is exposed to a set of hidden hyperlinks ("Easter Eggs") within the course and earns trivially small amounts of course credit for finding them. While controlling for demographics and initial effort, finding each additional Easter Egg is associated with a 0.8 percentage point increase in final grade. This effect is even stronger for low performers: for those below the median grade before the first Easter Egg, each find increases final grade by 1.3 points. The treatment advantages low-performing students more than their high-achieving counterparts, thus helping to reduce the education gap at extremely low cost to course developers.

Description
Aberrant signaling through the canonical RAS/RAF/MEK/ERK (ERK/MAPK) pathway leads to the pathology of a group of neurodevelopmental disorders called RASopathies. RASopathies are caused by germline mutations in the ERK/MAPK pathway and have an incidence of approximately 1:2000 births. The majority of RASopathies stem from mutations that cause gain-of-function in the ERK/MAPK pathway. In this study, we have begun to unravel the roles that GABAergic interneurons play in the pathology of RASopathies. Our data demonstrate that gain-of-function ERK/MAPK signaling expressed in a GABAergic interneuron-specific fashion leads to forebrain hyperexcitability in mutant mice. Further, some GABAergic interneurons experience activated-caspase 3 mediated apoptosis in the embryonic subpallium, leading to a loss of PV-expressing interneurons in the somatosensory cortex. We found that pharmaceutical intervention during embryogenesis using a MEK1 inhibitor may be effective in preventing apoptosis of these neurons. Future work is still needed to understand the mechanism of the death of GABAergic interneurons and to further pursue therapeutic approaches. Taken together, this study suggests potential roles of cortical GABAergic interneurons in ERK/MAPK-linked pathologies and indicates possible approaches to provide therapy for these conditions.

Description
The purpose of this study was to examine the lasting effects of repealed discriminatory laws on African Americans' college attendance rates and experiences. It examined the way that laws that targeted African Americans specifically created a lasting environment long after being declared unconstitutional. These persist to this day and affect their ability to attend higher education. To study the long reaching effects of these laws, I conducted semi-structured interviews with African-Americans, some of whom attended higher education, while others did not. Common important themes were identified through these interviews, including: Environmental and Institutional Factors, Support Systems, and Role Models, the dynamics of which showed lasting effects attributable to discriminatory laws.

Description
This paper explores the universe of non-performing loans and tries to examine the effects that a sharp increase in NPLs would cause. The first part of the paper explores some of the most shared definitions of NPL as well as the accounting treatment under IFRS (International Financial Reporting Standards). In the second part of the paper, literature regarding determinants of NPLs is summarized and categorized into three broad categories: macroeconomic determinants, institutional variables, and bank-specific variables. Eventually, in the last part of the paper, a fictional bank is built and tested against a two and three standard deviation NPL events. The worst loss occurring in the simulated events eroded 26% of the capital (2.55% of the assets) forcing the fictional bank to recapitalize and experience expensive recovery processes.

Description
The rise in the number of antibiotic-resistant bacteria, due in part to the widespread use of antibiotics, has spawned new technological approaches for identifying novel antimicrobials with narrow specificity. Current antibiotic treatment regimens and anti-tuberculosis drugs are not effective at treating Mycobacterium abscessus; therefore, antimicrobial peptides have gained prominence as alternative antimicrobials due to their specificity towards anionic bacterial membranes, rapid action, and inability for the bacteria to develop resistance by acting against the cell membrane. Our group has developed a high-density peptide microarray consisting of 125,000 random synthetic peptides for rapid screening of antimicrobial peptides against M. abscessus. From the array screening, the peptides that interacted with the mycobacterial cell surface were synthesized and subsequent inhibitory, bactericidal, and toxicity assays were performed. Additionally, minimum inhibitory concentration assays were performed with these peptides against Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli in order to determine if inhibitory activity was observed against Gram-positive and Gram-negative bacteria. Six peptides, out of the 125,000 peptides screened, had inhibitory activity against M. abscessus and low toxicity (< 10%) against human red blood cells. One peptide also exhibited inhibitory activity against S. aureus and E. coli. To determine combination effects, antimicrobial synergy assays will be performed with the six peptides and clarithromycin

Description
This study seeks to understand what design factors best aid in the elicitation of behaviors, specifically disclosure behaviors, from one party to another with the intent to provide some form of service. I looked at the medical industry to see how to create the best possible quality of care all while ensuring that the patient information is collected accurately and quickly. With healthcare in the United States becoming increasingly expensive along with the multitude of people seeking attention, the time that physicians have is scare. This scarcity can affect the type and quality of care that a patient would receive. Therefore, creating an online form to gather patient data would reduce time so long as the information was collected via a trusted method and patients were honest in their disclosure. The quality of the face-to-face time in a physician’s office would increase with increased honesty from patients, as the physician would be able to properly prepare for the appointment. This study examines whether screen lighting and typeface could influence a patient's disclosure of problem behaviors, such as smoking or drinking, the patient's rating of the importance of honesty, and the patient's perceptions of privacy and confidentiality during the disclosure. The results showed that Sans Serif [Arial] typeface was more effective in eliciting problem behavior disclosure. Perceptions and disclosure in relation to background color did not yield overwhelming results either way.

Description
With the coming advances of computational power, algorithmic trading has become one of the primary strategies to trading on the stock market. To understand why and how these strategies have been effective, this project has taken a look at the complete process of creating tools and applications to analyze and predict stock prices in order to perform low-frequency trading. The project is composed of three main components. The first component is integrating several public resources to acquire and process financial trading data and store it in order to complete the other components. Alpha Vantage API, a free open source application, provides an accurate and comprehensive dataset of features for each stock ticker requested. The second component is researching, prototyping, and implementing various trading algorithms in code. We began by focusing on the Mean Reversion algorithm as a proof of concept algorithm to develop meaningful trading strategies and identify patterns within our datasets. To augment our market prediction power (“alpha”), we implemented a Long Short-Term Memory recurrent neural network. Neural Networks are an incredibly effective but often complex tool used frequently in data science when traditional methods are found lacking. Following the implementation, the last component is to optimize, analyze, compare, and contrast all of the algorithms and identify key features to conclude the overall effectiveness of each algorithm. We were able to identify conclusively which aspects of each algorithm provided better alpha and create an entire pipeline to automate this process for live trading implementation. An additional reason for automation is to provide an educational framework such that any who may be interested in quantitative finance in the future can leverage this project to gain further insight.

Description
This thesis explores the power of food to transcend cultural and racial borders and to act as a common ground, bringing people of all different backgrounds together. Through globalization, there is an increased movement of people from their homeland to different regions around the world and with this migration comes the spread of their culture and cuisine to new areas. This spreading of culture often creates friction and tension amongst other cultures, however as this thesis argues, with increased diversity, there is the great potential for greater interaction with other cultures and therefore greater appreciation. The key aspect of this thesis is the ways in which food can be used as a tool to overcome racial barriers and serve as a means of positive expression of a culture. I hope to show that by engaging with a culture through its cuisine, one can arguably build a greater appreciation for that culture and therefore lower their preconceived notions and stereotypes.

Description
RISE Tutoring is an ASU student organization which helps refugee youth achieve academic and personal success through tutoring and mentorship. As a member of RISE Tutoring for three years, the researcher sought to document and analyze the program’s impact on the Phoenix refugee community. It was determined that video documentation, with its ability to capture both visual and verbal testimony, was the ideal holistic approach to assess and share this impact. The researcher hypothesized that RISE Tutoring adds value to the lives of its tutors and students through the multidimensional growth––educational, personal, and cultural––it facilitates for all. Methods of data collection were limited to video and audio, but approval from the Institutional Review Board and consent from all participants were obtained prior to the project’s start. The final video, filmed and edited with the help of a professional videographer, was 20 minutes and 21 seconds in length. The findings derived from the recorded interviews with students, tutors, and community leaders, and from the footage of tutoring and group activities, validated the researcher’s hypothesis. Viewers of the video can witness the bonding of tutors and students; hear the pride in the voices of the tutors and see the passion in their eyes when they speak of their students; and feel the joy and excitement that the program brings to its students’ lives. This project transformed the personal experiences of participants into a collective RISE Tutoring identity which can now be presented, for the first time, to the public. The video also aimed to help RISE Tutoring share its meaningful work and improve its marketing efforts, thereby enabling the organization to recruit more tutors and students, build new partnerships, and fundraise. Through the fulfillment of these goals, the video will empower the organization to effect greater change in the community.

Description
Fossil fuels have been the primary source of energy in the world for many decades. However, they are among the top contributors of the greenhouse gas emissions in the atmosphere. The objective of this research was to produce a more environmentally friendly biofuel from Algae-Helix and Salicornia biomasses. Experiments were conducted using a hydrothermal liquefaction (HTL) technique in the HTL reactor to produce biofuel that can potentially replace fossil fuel usage. Hydrothermal Liquefaction is a method used to convert the biomass into the biofuels. HTL experiments on Algae-Helix and Salicornia at 200°C-350°C and 430psi were performed to investigate the effect of temperature on the biocrude yield of the respective biomass used. The effect of the biomass mixture (co-liquefaction) of Salicornia and algae on the amount of biocrude produced was also explored. The biocrude and biochar (by-product) obtained from the hydrothermal liquefaction process were also analyzed using thermogravimetric analyzer (TGA). The maximum biocrude yield for the algae-helix biomass and for the Salicornia biomass were both obtained at 300°C which were 34.63% and 7.65% respectively. The co-liquefaction of the two biomasses by 50:50 provided a maximum yield of 17.26% at 250°C. The co-liquefaction of different ratios explored at 250°C and 300°C concluded that Salicornia to algae-helix ratio of 20:80 produced the highest yields of 22.70% and 31.97%. These results showed that co-liquefaction of biomass if paired well with the optimizing temperature can produce a high biocrude yield. The TGA profiles investigated have shown that salicornia has higher levels of ash content in comparison with the algae-helix. It was then recommended that for a mixture of algae and Salicornia, large-scale biofuel production should be conducted at 250℃ in a 20:80 salicornia to algae biocrude ratio, since it lowers energy needs. The high biochar content left can be recycled to optimize biomass, and prevent wastage.
