Description
The purpose of this project is to artistically express that our perceptions of the visual world are interrupted due to the often overlooked blinking of our eyes. The project was guided by two questions: 1) How is blink rate related to thought and emotion? 2) How does the process of blinking provide context to our life experiences? To link these two concepts together, I constructed a creative editing device that uses a live video feed of the user's eye blinking to randomly launch pre-existing footage of the user's significant life events. The process of creating this project occurred in three distinct steps. In the first step, I recorded 30-second videos to be used as a demonstration when exhibiting the device. In the second step, I attached a camera to a head mount to output a real time video of my eye blinking. In the third step, I created a Max patch that used the video feed of my eye as a trigger to play my pre-recorded clips. The final result was an evocative non-linear narrative of past personal experiences, and the development of the narrative itself is similar to the way in which humans recall memories. The visuals of the blinking eye were placed adjacent to the pre-recorded footage in order to mimic the positioning of two eyes on a face; one side of the display shows my actual eye, and the other side signifies looking back on what my eye has seen. The intended effect was to generate an awareness of the breaks in our vision and how this influences our existence.

Description
Amino acid analysis (AAA) of egg white lysozyme and bovine Achilles tendon collagen was performed using 1H solution-state nuclear magnetic resonance (NMR) spectroscopy. The proteins were hydrolyzed in 6M HCL with and without 0.02% phenol at 110\u00B0C for 24, 48, and 72 hours. For both proteins, 18 of 20 amino acids were characterized including hydroxyproline and hydroxylysine in collagen, using 1-dimensional (1D) and 2-dimensional (2D) NMR spectroscopy experiments. Errors ranging from <1% to 8% were seen in treatments with and without phenol. Both proteins could be correctly identified within their own species using the online database search AACompIdent. The proposed approach is a simple analytical technique that does not require the use of column separation or amino acid derivatization prior to compositional analysis.

Consumption of seafood poses a substantial threat to global biodiversity. Chemical contamination found in both wild-caught and farmed seafood also presents significant health risks to consumers. Flame retardants, used in upholstery, plastics, clothing, and other products to reduce fire danger, are of particular concern as they are commonly found in the marine environment and permeate the tissues of fish that are sold for consumption via multiple pathways. By summarizing various metrics of sustainability and the mercury content in consumed species of fish and shellfish, researchers have found that high levels of chemical contamination was linked with lesser fishery sustainability. I conducted a literature review of flame retardant content in seafood to further compare contamination and sustainability in addition to the initial analysis with mercury. My review suggests that the widespread issue of fishery collapse could be alleviated by demonstrating to stakeholders that many unsustainable fish stocks are mutually disadvantageous for both human consumers and the environment. Future research should address the need for the collection of data that better represent actual global contaminant concentrations in seafood.

For the ancient Greeks, music not only was esteemed for its social and entertaining value, but also because it reflected the beauty of the gods and their creations. Music furthermore “embodied larger universal principles and served as a vehicle for higher understanding.” According to Lippmann, the ancients believed that the universe “contains a harmony that controls both spatial and temporal phenomena” and “we can come to know the divine order of harmony more readily in ourselves than in the external world.” Gaining self-knowledge and awareness of one’s place in the world are significant and music is a means of gaining this consciousness. Ancient Greeks believed that music was inspired by the Greek goddesses known as the Muses. In this paper, I argue that, by gifting humans with divinely inspired music, the Muses help humans achieve this mindfulness of one‟s place in the world and attain immortality.

Description
Electrochemical sensors function by detecting electroactive species at the electrode surface of a screen printed sensor. As more force is applied, the concentration of electroactive species at the surface of the sensor increases and a larger current is measured. Thus, when all conditions including voltage are made constant, as in Amp i-t, a quantifiable current can be read and the force applied can be calculated. Two common electrochemical techniques in which current is measured, cyclic voltammetry(CV) and amperometric i-t(Amp i-t), were used. A compressible sensor capable of transducing a force and acquiring feedback was created.

Description
As robots become more prevalent, the need is growing for efficient yet stable control systems for applications with humans in the loop. As such, it is a challenge for scientists and engineers to develop robust and agile systems that are capable of detecting instability in teleoperated systems. Despite how much research has been done to characterize the spatiotemporal parameters of human arm motions for reaching and gasping, not much has been done to characterize the behavior of human arm motion in response to control errors in a system. The scope of this investigation is to investigate human corrective actions in response to error in an anthropomorphic teleoperated robot limb. Characterizing human corrective actions contributes to the development of control strategies that are capable of mitigating potential instabilities inherent in human-machine control interfaces. Characterization of human corrective actions requires the simulation of a teleoperated anthropomorphic armature and the comparison of a human subject's arm kinematics, in response to error, against the human arm kinematics without error. This was achieved using OpenGL software to simulate a teleoperated robot arm and an NDI motion tracking system to acquire the subject's arm position and orientation. Error was intermittently and programmatically introduced to the virtual robot's joints as the subject attempted to reach for several targets located around the arm. The comparison of error free human arm kinematics to error prone human arm kinematics revealed an addition of a bell shaped velocity peak into the human subject's tangential velocity profile. The size, extent, and location of the additional velocity peak depended on target location and join angle error. Some joint angle and target location combinations do not produce an additional peak but simply maintain the end effector velocity at a low value until the target is reached. Additional joint angle error parameters and degrees of freedom are needed to continue this investigation.

My thesis is on the subject of mentoring. I researched the benefits and the styles of programs available and then used my research to create a survey to give to IDSA national members to see what they believe would make a good mentoring program. From there I tried to improve the current ASU IDSA mentoring program.

Freewheelin': The American Counterculture in Museums is the first study to explore American museums that collect artifacts from the counterculture era at length. Examining institutions whose specialized collections and histories represent the recent, dynamic social movements of the mid-twentieth century begets particular institutional challenges and extraordinary opportunities; both factors causing the evolution of some American history museums into premier social history centers. I have focused on four institutions for research: the Beat Museum, the GLBT History Museum, the Rock and Roll Hall of Fame, and the Museum of Sex. The analysis of each organization contains a brief account of the history they strive to preserve, a case study of their professional operations, and objective recommendations. Ultimately through researching the four selected institutions and museum studies at large, it was determined that certain collective features are propelling a paradigm shift in modern American history museums.

Description
The role of retention and forgetting of context dependent sensorimotor memory of dexterous manipulation was explored. Human subjects manipulated a U-shaped object by switching the handle to be grasped (context) three times, and then came back two weeks later to lift the same object in the opposite context relative to that experience on the last block. On each context switch, an interference of the previous block of trials was found resulting in manipulation errors (object tilt). However, no significant re-learning was found two weeks later for the first block of trials (p = 0.826), indicating that the previously observed interference among contexts lasted a very short time. Interestingly, upon switching to the other context, sensorimotor memories again interfered with visually-based planning. This means that the memory of lifting in the first context somehow blocked the memory of lifting in the second context. In addition, the performance in the first trial two weeks later and the previous trial of the same context were not significantly different (p = 0.159). This means that subjects are able to retain long-term sensorimotor memories. Lastly, the last four trials in which subjects switched contexts were not significantly different from each other (p = 0.334). This means that the interference from sensorimotor memories of lifting in opposite contexts was weaker, thus eventually leading to the attainment of steady performance.
