Description
The current EPA regulation for total chromium in drinking water is the MCL standard of 0.1 milligrams per liter or 100 parts per billion (ppb) to avoid dermatological effects. With a toxicology study released in 2008 by the Department of Health and Human Services noting that hexavalent chromium is carcinogenic, the EPA is currently reviewing this MCL standard. During this review, the EPA provides monitoring guidance that requires quarterly sampling of surface water for hexavalent chromium. However, these samples monitor the instant in time that they were taken, and do not account for varying concentrations that are time-dependent. This research seeks to develop a method for monitoring hexavalent chromium in water. Using ion exchange technology, passive samplers were developed and installed at the Chandler Water Treatment Plant for a week-long monitoring event. Results show that passive samplers using ion exchange technology provide an accurate assessment of the average concentration of total chromium within the water treatment plant's effluent with 90.3% recovery of Cr(VI) in SIR-100 resin and 62.6% recovery in SIR-700.

Description
Much research has been devoted to identifying trends in either convergence upon a neoliberal model or divergence among welfare states in connection to globalization, but most research has focused on advanced industrialized countries. This has limited our understanding of the current state of convergence or divergence, especially among welfare states in developing regions. To address this research gap and contribute to the broader convergence vs. divergence debate, this research explores welfare state variation found within Latin America, in terms of the health policy domain, through the use of cross-national data from 18 countries collected between the period of 1995 to 2010 and the application of a series of descriptive and regression analysis techniques. Analyses revealed divergence within Latin America in the form of three distinct welfare states, and that among these welfare states income inequality, trust in traditional public institutions, and democratization, are significantly related to welfare state type and health performance.

Description
The growth the nonprofit sector has experienced not only nationally but within the state of Arizona has been tremendous. The growth occurs one organization at a time and the research looks at the motivators as to why individuals part take in a profit less sector. The research focuses on nonprofits within Maricopa County offering human services. A combination of qualitative methods were used to guide the research. Interviews with nonprofits founders was the main form of data collection. The findings revealed self-efficacy, spirituality, and personal relations played a pivotal role as motivators for the participants. The findings also illuminated the role class, gender, and race play in the structural arrangement and opportunities to engage in adopting a nonprofit organization.

Description
The recent emergence of DNA-based diagnostics increases the demand for rapid DNA sequencing technologies. One method to achieve this is to pass DNA through a nanopore, recording the trans-membrane current with a low-noise current amplifier. The project outlined in this report aims to demonstrate a design of a custom amplifier that offers a wider bandwidth than current designs while maintaining a low signal to noise ratio. The novel amplifier has been designed such that a multi-stage RF signal chain is integrated with an existing amplifier circuit to achieve DNA translocation. Both the existing amplifier circuit and the RF signal chain have produced outputs showing that the two amplifiers are functional and both low frequency signals and high frequency signals can be amplified with this comprehensive circuit design.

Description
Biofeedback music is the integration of physiological signals with audible sound for aesthetic considerations, which an individual’s mental status corresponds to musical output. This project looks into how sounds can be drawn from the meditative and attentive states of the brain using the MindWave Mobile EEG biosensor from NeuroSky. With the MindWave and an Arduino microcontroller processor, sonic output is attained by inputting the data collected by the MindWave, and in real time, outputting code that deciphers it into user constructed sound output. The input is scaled from values 0 to 100, measuring the ‘attentive’ state of the mind by observing alpha waves, and distributing this information to the microcontroller. The output of sound comes from sourcing this into the Musical Instrument Shield and varying the musical tonality with different chords and delay of the notes. The manipulation of alpha states highlights the control or lack thereof for the performer and touches on the question of how much control over the output there really is, much like the experimentalist Alvin Lucier displayed with his concepts in brainwave music.

Description
A major goal of the Center for Biosignatures Discovery Automation (CBDA) is to design a diagnostic tool that detects novel cancer biosignatures at the single-cell level. We designed the Single-cell QUantitative In situ Reverse Transcription-Polymerase Chain Reaction (SQUIRT-PCR) system by combining a two-photon laser lysis (2PLL) system with a microfluidic reverse transcriptase-quantitative polymerase chain reaction (RT-qPCR) platform. It is important to identify early molecular changes from intact tissues as prognosis for premalignant conditions and develop new molecular targets for prevention of cancer progression and improved therapies. This project analyzes RNA expression at the single-cell level and presents itself with two major challenges: (1) detecting low levels of RNA and (2) minimizing RNA absorption in the polydimethylsiloxane (PDMS) microfluidic channel. The first challenge was overcome by successfully detecting picogram (pg) levels of RNA using the Fluidigm (FD) BioMark™ HD System (Fluidigm Corporation, South San Francisco, CA) for RT-qPCR analysis. This technology incorporates a highly precise integrated fluidic circuit (IFC) that allows for high-throughput genetic screening using microarrays. The second challenge entailed collecting data from RNA flow-through samples that were passed through microfluidic channels. One channel was treated with a coating of polyethylene glycol (PEG) and the other remained untreated. Various flow-through samples were subjected to RT-qPCR and analyzed using the FD FLEXsix™ Gene Expression IFC. As predicted, the results showed that the treated PDMS channel absorbed less RNA than the untreated PDMS channel. Once the optimization of the PDMS microfluidic platform is complete, it will be implemented into the 2PLL system. This novel technology will be able to identify cell populations in situ and could have a large impact on cancer diagnostics.

Description
This project covered different components to strengthen Model United Nations organizations, especially programs in Arizona itself. The lack of strong programs in Arizona can be attributed in many ways to a lack of resources, and this project's work aims to bolster programs by providing some resources. The written component contains a write-up of a 2013 High School Model United Nations Conference at Arizona State University; a write-up of a 2014 Middle School Model United Nations Conference at Arizona State University; a guide on how to run such a conference, focused at the high school level; a university-level curriculum that integrates a Model United Nations organization into a classroom setting, including assignments and; a grade school lesson plan with seven lessons that focuses on teaches students about international relations and global affairs while preparing them for a Model United Nations conference.

Description
This thesis aims to analyze and explain the resurgence of the superhero genre, particularly in recent cinema, directly following the terrorist attacks on September 11, 2001. It will also deconstruct the current American political landscape and define how popular culture has historically reflected real-world issues. The study draws heavily on the political ideology of neoliberalism and Henry Jenkins' media theory of convergence culture. I ultimately argue in the course of the analysis that viewers of these superhero films, regardless of their interest in comic books, cathartically release their fears and post-9/11 anxiety through cinematic escapism. It will also relay the evolution of the superhero in the last seventy years as a way to show the effects current events have on popular culture and history, using Captain America and Iron Man as examples of shifting American values.

Who Put Out the Light? A Study of the FInancial Ruin in Greece, is a research study on the Greek economic crisis that led to Greece's financial ruin and nearly put the country into bankruptcy. I conducted a series of interviews on people from all walks of life while in Greece during the Summer of 2013. I investigated all of the possible factors that may have led to the catastrophic events they are currently undergoing and how each person was severely impacted. Moreover, I compared each person's political beliefs and how those beliefs may have factored into what they believe caused the beginning of this turmoil. Through this process, I have also come to find that there are many obscure and eye-opening laws that have been put in place both in Greece by their government, as well as by the European Union that may have factored into the detriment of the country. Furthermore, I wanted to depict the personal anguish of the people through pictures, thus adding a photojournalistic aspect to my thesis project.
