Description
This study focused on the connection between the EnvZ/OmpR two-component regulatory system and the iron homeostasis system in Escherichia coli, specifically how a mutant form of EnvZ11/OmpR is able to reduce the expression of fepA::lacZ, a reporter gene fusion in E. coli. FepA is one of several outer membrane siderophore receptors that allow extracellular siderophores bound to iron to enter the cells to power various biological processes. Previous studies have shown that in E. coli cells that expressed a mutant allele of envZ, called envZ11, which led to altered expression of various iron genes including down regulation of fepA::lacZ. The wild type EnvZ/OmpR system is not considered to regulate iron genes, but because these envz11 strains had downregulated fepA::lacZ, this study was undertaken to understand the connection and mechanisms of this downregulation. A large number of Lac+ revertants were obtained from the B32-2483 strain (envz11 and fepA::lacZ) and 7 Lac+ revertants that had reversion mutations not directly correcting the envZ11 allele were further characterized. With P1 phage transduction genetic mapping that involved moving a kanamycin resistance marker linked to fepA::lacZ, two Lac+ revertants were found to have their reversion mutations in the fepA promoter region, while the other five revertants had their mutations mapping outside the fepA region. These two revertants underwent DNA sequencing and found to carry two different single base pair mutations in two different locations of the fepA promoter region. Each one is in the Fur repressor binding region, but one also may have affected the Shine-Dalgarno region involved in translation initiation. All 7 reveratants underwent beta-galactosidase assays to measure fepA::lacZ expression. The two revertants that had mutations in the fepA promoter region had significantly increased fepA activity, with the revertant with the Shine-Dalgarno mutation having the most elevated fepA expression. The other 5 revertants that did not map in the fepA region had fepA expression elevated to the same level as that found in the wild type EnvZ/OmpR background. The data suggest that the negative effect of envZ11 can be overcome by multiple mechanisms, including directly correcting the envZ11 allele or changing the fepA promoter region.

Description
Unauthorized confronts the relationship between technology and personhood in the modern world. More specifically, it addresses the personal and social effects of border politics within the frame of cyber crime. The short film takes place in the near future where a hacker can create citizenship for anyone she wants, effectively turning anyone into a legal person in the United States. This parallels the real life struggles of unauthorized immigrants trying to gain a new life this side of the border despite the overwhelming backlash from the conservative and xenophobic population. The main character's ability to grant citizenship forces the viewer to confront what being a person really means. The film also alludes to the popularized antics of modern day hackers and whistleblowers who are often turned into heroes for fighting the establishment despite their character flaws. The protagonist of Unauthorized struggles through underhanded sexism and blatant racism as well as her own personal struggles with drug addiction and failed relationships. These are very real struggles women face in technology jobs and life in general. The main character's actions ultimately destroy every relationship that she's established, including the connection to her own family. This film, in short, is about the walls people build between each other, both physical and social.

Description
For this thesis, the authors would like to create a hypothetical Private Equity Real Estate Investment firm that focuses on creating value for partners by taking an opportunistic approach to acquiring under-performing urban multi-family properties with large upside potential for investing. The project will focus on both the market analysis and financial modeling associated with investment strategy and transactions. There is a substantial amount of complexity within commercial real estate and this thesis seeks to offer an accurate and comprehensive documentary of the process, while simplifying it for everyday readers. Additionally, there are a significant amount of risk factors associated with investment decisions, so the best practices from the industry documented in this manuscript are valuable tools for successful investing in the future. To gain the most profound and reliable industry knowledge, the authors leveraged the experience of dozens of industry professionals through research and personal interviews. Through careful analysis, the authors were able to ascertain the current economic position in the real estate cycle and to create a plan for future investing. Additionally, they were able to identify and evaluate a specific asset for purchase. As a result, the authors found that multifamily properties are a sound investment for the next two years and that the company should slowly start to shift directions to office and retail in 2018.

Description
The ability to draft and develop productive Major League players is vital to the success of any MLB organization. A core of cost-controlled, productive players is as important as ever with free agent salaries continuing to rise dramatically. In a sport where mere percentage points separate winners from losers at the end of a long season, any slight advantage in identifying talent is valuable. This study examines the 2004-2008 MLB Amateur Drafts in order to analyze whether certain types of prospects are more valuable selections than others. If organizations can better identify which draft prospects will more likely contribute at the Major League level in the future, they can more optimally spend their allotted signing bonus pool in order to acquire as much potential production as possible through the draft. Based on the data examined, during these five drafts high school prospects provided higher value than college prospects. While college players reached the Majors at a higher rate, high school players produced greater value in their first six seasons of service time. In the all-important first round of the draft, where signing bonuses are at their largest, college players proved the more valuable selection. When players were separated by position, position players held greater expected value than pitchers, with corner infielders leading the way as the position group with the highest expected value. College players were found to provide better value than high school players at defensively demanding positions such as catcher and middle infield, while high school players were more valuable among outfielders and pitchers.

Description
The loss of a loved one through suicide is a traumatic life event that brings about considerable emotional turmoil. In the present study, the term suicide loss survivor refers to an individual who is a family member or a friend of a person who died by suicide. Through the three chosen methods of gathering data, which are online surveys, in person interviews, and photography sessions, researchers highlight the personal experience of thirty-three suicide loss survivors. Supported by these various methods of data collection are the unique issues that accompany the bereavement of a suicide loss. The areas of focus are the emotional trauma, social stigma, and postvention resources utilized or made available to suicide loss survivors. Throughout interviews with suicide loss survivors, some of whom also identified as Arizona State University students, an additional opportunity for research emerged. Participants identified that Arizona State University is not effectively providing suicide awareness and prevention materials and training to its community, including staff and students. Recommendations for how Arizona State University can improve their current processes are discussed in the conclusion. By implementing the recommendations of prevention and postvention care, it is possible to educate students and staff and, in turn, allow Arizona State University to foster a culture of empathy for existing suicide loss survivors, while working on decreasing the risk of future suicides. This creative project and narrative analysis was performed by two individuals who themselves are suicide loss survivors and have taken their personal experiences as a foundation for the project's need.

Description
This creative project consists of three short stories with a common theme of release, letting go, and exhalation. Nymphal Instar is a story about Tommy, a young boy, and his encounter with his uncle, a troubled man who has just returned from war. The story explores the idea of growth and maturation, and the ability to move past and let go of trauma. A Cat Goes Away is about a young man, Richard, who is required to simultaneously deal with the loss of his cat and the suicide attempts of his sister. He also runs into his sister's ex-husband and is forced to deal with him. The story explores the difficulty in recognizing one's own emotions and the importance of knowing the difference between what one can change and what one cannot. Since Diagnosis is a story about Kate, a woman who has just been diagnosed with cancer and who is unable to tell her loved ones. The story explores acceptance and the idea that letting go can allow one to live more fully. Though the three stories are disparate in their characters and events, they share a commonality in their endings and in the final realizations of the characters. There is a focus on the importance of breath and breathing, and the essentiality of acceptance and release.

Millennials are the group of people that make up the newer generation of the world's population and they are constantly surrounded by technology, as well as known for having different values than the previous generations. Marketers have to adapt to newer ways to appeal to millennials and secure their loyalty since millennials are always on the lookout for the next best thing and will "trade up for brands that matter, but trade down when brand value is weak", it poses a challenge for the marketing departments of companies (Fromm, J. & Parks, J.). The airline industry is one of the fastest growing sectors as "the total number of people flying on U.S. airlines will increase from 745.5 million in 2014 and grow to 1.15 billion in 2034," which shows that airlines have a wider population to market to, and will need to improve their marketing strategies to differentiate from competitors (Power). The financial sector also has a difficult time reaching out to millennials because "millennials are hesitant to take financial risks," as well as downing in college debt, while not making as much money as previous generations (Fromm, J. & Parks, J.). By looking into the marketing strategies, specifically using social media platforms, of the two industries, an understanding can be gathered of what millennials are attracted to. Along with looking at the marketing strategies of financial and airline industries, I looked at the perspectives of these industries in different countries, which is important to look at because then we can see if the values of millennials vary across different cultures. Countries chosen for research to further examine their cultural differences in terms of marketing practices are the United States and England. The main form of marketing that was used for this research were social media accounts of the companies, and seeing how they used the social networking platforms to reach and engage with their consumers, especially with those of the millennial generation. The companies chosen for further research for the airline industry from England were British Airways, EasyJet, and Virgin Atlantic, while for the U.S. Delta Airlines, Inc., Southwest Airlines, and United were chosen. The companies chosen to further examine within the finance industry from England include Barclay's, HSBC, and Lloyd's Bank, while for the U.S. the banks selected were Bank of America, JPMorgan Chase, and Wells Fargo. The companies for this study were chosen because they are among the top five in their industry, as well as all companies that I have had previous interactions with. It was meant to see what the companies at the top of the industry were doing that set them apart from their competitors in terms of social media marketing content and see if there were features they lacked that could be changed or improvements they could make. A survey was also conducted to get a better idea of the attitudes and behaviors of millennials when it comes to the airline and finance industries, as well as towards social media marketing practices.

This is an analysis of broad racial discourse through a critical race theory: Responsibility Avoidance Discourse (RAD). RAD is coded English that communicates meaning through connotation, avoidance, and implication as a means of securing its main purposes: enforcing white supremacy, obscuring inequality, and hindering significant racial progress. RAD is extremely effective at directing discussion away from arguments that might induce self-reflexivity or question white privilege. It focuses on discrediting others as a means of legitimizing whiteness. I analyze examples of it from a variety of sources—from political discourse to media coverage and social media trends—to demonstrate its manifestations throughout society.

Description
Memory CD8+ T-cells can persist in the absence of antigen, primed for immediate activation and proliferation if later exposed to the same antigen. These cytotoxic lymphocytes provide long-term immunity following an acute infection. Studies have observed that intermediate levels of general T cell transfer prior to infection may cause an inappropriate response resulting in increased pathology rather than prevention. Therefore, our study focused on a memory CD8 T-cell therapy using lymphocytic choriomeningitis virus (LCMV) specific splenocytes, which activate and proliferate at an accelerated pace compared to that of naive T-cells. LCMV is a natural murine pathogen which also poses a zoonotic infection threat to humans, and the effect of immune cell vaccination therapies for LCMV is not fully understood. We observed the effect of multiple memory CD8 T cell dosage levels on overall disease and memory CD8 T-cell response to the virus. Infection by exposure to a carrier was shown to have a reduced impact on mice receiving higher doses of memory T cells prior to infection compared to mice receiving less or no memory cells. Higher presence of activated memory cells were shown to correlate with less disease-related weight loss and accelerated recovery times. Survival rate after exposure to carriers was not shown to be affected by dosage level, warranting further research regarding the prevalence of the immunopathology observed in other studies in natural murine transmission models.

Description
I saw a Dove ad called "Real Beauty Sketches" where a group of women described themselves to a sketch artist, and then a complete stranger described them to the same artist. By the end of the ad, it's apparent that the women, when describing themselves, were very critical of all their features. When total strangers described them the resulting portrait was more beautiful to the women. The take-away from the campaign was that others see more beauty in you than you do in yourself. I explored that idea through my thesis. My aim in this project was to learn to see the beauty in myself through personal artistic expression. I completed a series of self-portraits; for about four months straight I drew one portrait of myself every single day. I also recorded my thoughts in a diary entry as I drew my portrait, hoping to capture my emotions and moods during that day. The resulting outcome of my creative project is twofold. The physical outcome is about 100 self-portraits and daily diary entries that represent the creative thesis project I pursued. The second outcome cannot be physically seen. I have discovered more about myself in four months than I have in twenty years. I have begun to see myself differently, and positively. This thesis project turned into a journey of self-exploration, and I'm looking forward to what the future holds for me.
