Description
A desk provides an interesting forum between two people. The first party sits behind the desk while the second approaches with a question. The desk presents itself as a stage for the drama of that conversation to take place; as all furniture and property do, we naturally make assumptions about the owner based on the things they possess. Just as a Ferrari says one thing while a truck says something different, our furniture conveys a similar sensation. The desk is special because it acts as a stage - it can create a very subtle first impression of the person who owns it. The question then becomes, "what should I try to convey through the desk I sat behind?". If someone walked into my office and looked strictly at my desk, what impression would I want to give them about who I am as an individual? I conjunction with this question about the design of the desk itself comes to another question about the materials used. This thesis goes into the symbolic nature of wood in modern and ancient times across cultures, explores wood in modern construction today and explores the source of the wood used in this specific project through a supplier analysis of Porter Barn Wood. Porter Barn Wood is a local Phoenix company that specializes in reclaimed barn wood delivered from the east coast. Determining the story of how the wood got to Phoenix and to the company that made it possible was just as important to the story of the desk as the wood itself. Overall, this project explored my ability to construct a desk and build a story around that piece of art while maintaining a business mindset throughout. It was eye-opening to me and I would encourage you to read further!

Description
In the pursuit of sustainable sources of energy that do less harm to the environment, numerous technologies have been developed to reduce carbon emissions in the atmosphere. The implementation of carbon capture and storage systems (CCS) has played a crucial role in reducing CO2 emissions, but depleting storage reserves and ever-increasing costs of sequestrating captured CO2 has prompted the idea of utilizing CO2 as soon as it is produced (i.e. carbon capture and utilization, or CCU) and storing any remaining amounts. This project analyzes the cost of implementing a delafossite CuFeO2 backed CCU system for the average US coal-burning power plant with respect to current amounts of CO2 captured. Beyond comparing annual maintenance costs of CCU and CCS systems, the project extends previous work done on direct CO2 conversion to liquid hydrocarbons by providing a protocol for determining how the presence of NO affects the products formed during pure CO2 hydrogenation. Overall, the goal is to gauge the applicability of CCU systems to power plants with a sub 10-year lifespan left, whilst observing the potential revenue that can be potentially generated from CCU implementation. Under current energy costs ($0.12 per kWh), a delafossite CuFeO2 supported CCU system would generate over $729 thousand in profit for an average sized supercritical pulverized coal power (SCPC) plants selling diesel fuel created from CO2 hydrogenation. This amount far exceeds the cost of storing captured CO2 and suggests that CCU systems can be profitable for SCPC power plants that intend to burn coal until 2025.

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.

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
Existing research into the health benefits of insurance fall into two major categories \u2014 observational and experimental. Observational studies have centered on data sets from before 2000 and focus on the mortality differences between the privately insured and the uninsured. Experimental studies began with Massachusetts' 2006 health reform and continued after the passage of the Affordable Care Act. These studies measure the effects of public insurance among the coverage expansion populations. These two bodies of literature come to ambiguous and contradictory conclusions to the mortality effects and health value of insurance. This study extends the observational methodologies to the publicly insured in samples from the National Health and Nutrition Examination Survey in both the 1988-1994 survey and the 2001-2002 survey. Using the Cox Proportional Hazard model, this study estimates the hazard ratios faced by the privately and publicly insured compared to the uninsured. This study finds the publicly insured face hazards 1.5 times those of the uninsured (p<.001), while the privately insured do not face hazards significantly different from those of the uninsured. Literature suggests that some unobserved characteristic of the publicly insured are influencing their mortality. Interacting with participants health reveals that these differences across groups shrink as health declines. Experimental literature suggests that public insurance lowers the uninsured risk from "healthcare amenable" conditions. Treatment of these conditions may explain the hazard reductions among the uninsured in non-excellent health. The high risk of the publicly insured in excellent health defies explanation.

Description
Investment banking is an industry that has historically had a low representation of minorities. Diversity has become a common buzz word among human resource professionals and American firms have worked hard over the last decades to diversify their ranks. The positive effect that diversity of thought has on performance has fueled a high demand for increasingly diverse and inclusive work environments. Conversely, investment banking (typically considered a profession for upper-class, white males) has not made any strides in regard to attracting more diverse talent to Wall Street. Wall Street firms have been unsuccessful in attracting students of color and women to the industry. In this study, interest levels of Black students will be explored to understand if the shortage of Black bankers is due to supply rather than demand.

Description
This paper examines the qualitative and quantitative effects of the 2008 financial crisis on the current landscape of the investment banking industry. We begin by reviewing what occurred during the financial crisis, including which banks took TARP money, which banks became bank holding companies, and significant mergers and acquisitions. We then examine the new regulations that were created in reaction to the crisis, including the Dodd-Frank Act. In particular, we focus on the Volcker Rule, which is a section of the act that prohibits proprietary trading and other risky activities at banks. Then we shift into a quantitative analysis of the changes that banks made from the years 2005-2016. To do this, we chose four banks to be representative of the industry: Goldman Sachs, Morgan Stanley, J.P. Morgan, and Bank of America. We then analyze four metrics for each bank: revenue mix, value at risk, tangible common equity ratio, and debt to equity ratio. These provide methods for analyzing how banks have shifted their revenue centers to accommodate new regulations, as well as how these shifts have affected banks' risk levels and leverage. Our data show that all four banks that we observed shifted their revenue centers to flatter revenue areas, such as investment management, wealth management, and consumer banking operations. This was paired with fairly flat investment banking revenues across the board when controlling for overall market changes in the investment banking sector. Additionally, trading-focused banks significantly shifted their operations away from proprietary trading and higher risk activities. These changes resulted in lower value at risk measures for Goldman Sachs and Morgan Stanley with very minor increases for J.P. Morgan and Bank of America, although these two banks had low levels of absolute value at risk when compared to Goldman Sachs and Morgan Stanley. All banks' tangible common equity ratios increased and debt to equity ratios decreased, indicating a safer investment for shareholders and lower leverage. We conclude by offering a forecast of our expectations for the future, particularly in light of a Trump presidency. We expect less regulation going forward and the potential reversal of the Volcker Rule. We believe that these changes would result in more revenue coming from trading and riskier strategies, increasing value at risk, decreasing tangible common equity ratios, and increasing debt to equity ratios. While we do expect less regulation and higher risk, we do not expect these banks to reach pre-crisis levels due to the significant amount of regulations that would be particularly difficult for the Trump administration to reverse.

Description
In this essay, I discuss Islamic feminism from the point of view of its proponents. By this, I hope to engage Muslims and traditionalists. Islamic feminism is the fight for gender equality, as a challenge to the way traditional Islam has perpetuated patriarchal power structures in the Muslim world. Today, feminist sentiment is on the rise in the Islamic world as more and more women are becoming engaged in this fight for gender equality. Islamic feminism reclaims the Quran as its justification and involves the struggle for gender equality grounded in this justification. I divulge into two linked claims: a normative one where gender equality is justified in Islam, and a descriptive one which posits that male domination over interpretive powers has distorted the way Islam has been practiced traditionally, thus placing women in a disadvantaged position. Islamic feminists, I have found, seek to reject the widespread patriarchal interpretation of the Quran by first, reinterpreting the Quran as an equalizing force, and then implementing Islamic feminism in the public sphere. I show that they do this by engaging politically and civically through activism, education, and political involvement — this I refer to as civic Islam, highlighting that public engagement is an inherent Islamic duty. For this end, I cite several countries — including Iran, Yemen, Tunisia — in which Islamic feminists have taken up the mantle as activists, and what their impact has been through brief case studies. In the end, I include my reflection on Islamic feminism as a college-educated Muslim woman having grown up in a Western, liberal society.
