Description
Engineering is a heavily male-dominated field and females are significantly less likely to choose an engineering-related major or career path. At the age of six years old, females start believing that their male peers are smarter than them, leading them to pursue less ambitious careers. The children's book Lyla B. An Engineering Legacy was created to encourage more young girls to discover their own potential and pursue engineering as a career. To explore the efficacy of the book on its target consumers, a pilot study was performed with first and second grade children. The participants' engineering knowledge; fixed and failure mindset beliefs; STEM (Science, Technology, Engineering, and Math) interest, competency, and career aspirations; and stereotype beliefs were evaluated before and after being read the book to determine if the story has a positive impact on children. Additionally, the satisfaction of the participants towards both the book and main character were analyzed quantitatively and qualitatively. Overall, the results of the study suggest that the book has a positive impact on the interest and competency of STEM fields and the stereotype beliefs that the children had towards engineers. The study also suggests that the book decreases fixed and failure mindsets and that the participants were satisfied with the overall concept of the book and main character, Lyla.

Description
In this creative project, our goal was to establish a student lead service organization dedicated to raising money and awareness for a selected medical issue through an interactive carnival event. In doing so, we were able to identify the potential obstacles and pathways that are required for service organizations within Arizona State University. Our experience provides a guideline for future students looking to organize charitable events on campus. This paper discusses several essential skills for running a charitable student organization, including establishing a brand, managing finances, cultivating business relationships, and marketing the cause. It is our hope that future students can learn from our experience and find success in similar endeavors.

Description
Most daily living tasks consist of pairing a series of sequential movements, e.g., reaching to a cup, grabbing the cup, lifting and returning the cup to your mouth. The process by which we control and mediate the smooth progression of these tasks is not well understood. One method which we can use to further evaluate these motions is known as Startle Evoked Movements (SEM). SEM is an established technique to probe the motor learning and planning processes by detecting muscle activation of the sternocleidomastoid muscles of the neck prior to 120ms after a startling stimulus is presented. If activation of these muscles was detected following a stimulus in the 120ms window, the movement is classified as Startle+ whereas if no sternocleidomastoid activation is detected after a stimulus in the allotted time the movement is considered Startle-. For a movement to be considered SEM, the activation of movements for Startle+ trials must be faster than the activation of Startle- trials. The objective of this study was to evaluate the effect that expertise has on sequential movements as well as determining if startle can distinguish when the consolidation of actions, known as chunking, has occurred. We hypothesized that SEM could distinguish words that were solidified or chunked. Specifically, SEM would be present when expert typists were asked to type a common word but not during uncommon letter combinations. The results from this study indicated that the only word that was susceptible to SEM, where Startle+ trials were initiated faster than Startle-, was an uncommon task "HET" while the common words "AND" and "THE" were not. Additionally, the evaluation of the differences between each keystroke for common and uncommon words showed that Startle was unable to distinguish differences in motor chunking between Startle+ and Startle- trials. Explanations into why these results were observed could be related to hand dominance in expert typists. No proper research has been conducted to evaluate the susceptibility of the non-dominant hand's fingers to SEM, and the results of future studies into this as well as the results from this study can impact our understanding of sequential movements.

Description
In this paper, β-estradiol was characterized utilizing electrochemical impedance spectroscopy (EIS) techniques for the purpose of developing a multi-marker fertility sensor. β-estradiol was immobilized onto the surface of gold disk electrodes to find the optimal binding frequency of estradiol and its respective antibody, anti-17β-estradiol, which was determined to be 37.46Hz. At this frequency a logarithmic relationship between concentration and impedance (Z/ohm) was established creating a concentration calibration curve with a slope of 211 ohm/ln(pg mL-1), an R-squared value of 0.986 and a lower limit of detection of 742 fg mL-1. The specificity and cross-reactivity of the antibody with other hormones was tested through interferent and non-target experiments. Signal-to-noise ratio analysis verified that anti-17β-estradiol exhibited minimal chemical reactions with other hormones (SNR< 3) in non-target experiments. Additionally, there were minimal changes in the amount of signal collected during interferent testing, with albumin and follicle stimulating hormone having SNR values greater than 3. These results, along with the unique frequency response of the antibody-target binding reaction, allow for the possibility of using anti-17β-estradiol and β-estradiol for detecting multiple fertility biomarkers on a single sensor.

Description
Diabetes mellitus is a disease characterized by many chronic and acute conditions. With the prevalence and cost quickly increasing, we seek to improve on the current standard of care and create a rapid, label free sensor for glycated albumin (GA) index using electrochemical impedance spectroscopy (EIS). The antibody, anti-HA, was fixed to gold electrodes and a sine wave of sweeping frequencies was induced with a range of HA, GA, and GA with HA concentrations. Each frequency in the impedance sweep was analyzed for highest response and R-squared value. The frequency with both factors optimized is specific for both the antibody-antigen binding interactions with HA and GA and was determined to be 1476 Hz and 1.18 Hz respectively in purified solutions. The correlation slope between the impedance response and concentration for albumin (0 \u2014 5400 mg/dL of albumin) was determined to be 72.28 ohm/ln(mg/dL) with an R-square value of 0.89 with a 2.27 lower limit of detection. The correlation slope between the impedance response and concentration for glycated albumin (0 \u2014 108 mg/dL) was determined to be -876.96 ohm/ln(mg/dL) with an R-squared value of 0.70 with a 0.92 mg/dL lower limit of detection (LLD). The above data confirms that EIS offers a new method of GA detection by providing unique correlation with albumin as well as glycated albumin. The unique frequency response of GA and HA allows for modulation of alternating current signals so that several other markers important in the management of diabetes could be measured with a single sensor. Future work will be necessary to establish multimarker sensing on one electrode.

Description
Currently, the management of diabetes mellitus (DM) involves the monitoring of only blood glucose using self-monitoring blood glucose devices (SMBGs) followed by taking interventional steps, if needed. To increase the amount of information that diabetics can have to base DM care decisions off of, the development of an insulin biosensor is explored. Such a biosensor incorporates electrochemical impedance spectroscopy (EIS) to ensure an extremely sensitive platform. Additionally, anti-insulin antibody was immobilized onto the surface of a gold disk working electrode to ensure a highly specific sensing platform as well. EIS measurements were completed with a 5mV sine wave that was swept through the frequency spectrum of 100 kHz to 1 Hz on concentrations of insulin ranging from 0 pM to 100 μM. The frequency at which the interaction between insulin and its antibody was optimized was determined by finding out at which frequency the R2 and slope of the impedance-concentration plot were best. This frequency, otherwise known as the optimal binding frequency, was determined to be 459 Hz. Three separate electrodes were developed and the impedance data for each concentration measured at 459 Hz was averaged and plotted against the LOG (pM insulin) to construct the calibration curve. The response was calculated to be 263.64 ohms/LOG(pM insulin) with an R2 value of 0.89. Additionally, the average RSD was determined to be 19.24% and the LLD was calculated to be 8.47 pM, which is well below the physiological normal range. These results highlight the potential success of developing commercial point-of-care insulin biosensors or multi-marker devices operating with integrated insulin detection.

Description
Spending time outdoors can have a positive impact on the physical and mental health of individuals. These physiological and psychological benefits were comprehensively reviewed, accompanied by a brief history of these views in American society and how modern programs are promoting outdoor activity. Some of the populations targeted in this research include children, veterans, the elderly, and the clinically ill. A guidebook for Arizona outdoor adventures \u2014 containing original landscape photography \u2014 was created to encourage ASU students to explore local hikes, campsites, and other outdoor opportunities near the city of Phoenix. Each entry contained a brief description of the area or trail, along with the distance from the ASU Tempe campus and information on the length and difficulty of the hike, if applicable. A section at the end of the book was aimed at education readers on basic outdoor survival protocol, as many people venture into the wild with very little understanding of the dangers associated with their activities. A website was made that mirrors the guidebook, but was intended to be a more accessible method of sharing our information. The final component of the project involved maintaining a social media account over the course of the year, allowing us to expand our reach to people beyond ASU and this community. Over the course of the project, the account gained a large following, and several posted photos went on to be featured on prominent regional accounts. By combining the four components described previously, several resources were created for people, particularly students attending ASU, to gain a better understanding of the outdoor adventures available to them, and the benefits that spending time surrounded by nature can have.

Description
The goal of this creative project is to document my grandmother’s traditional Gujarati recipes with the hopes of preserving her life and passion for cooking. This process included library research to investigate the history of Indian and Gujarati cuisine, spending time in the kitchen documenting the recipes in their entirety, practicing them on my own, writing the cookbook and including passages that weave in the history, my grandmother’s stories, and techniques and tools. After completing this process, the significant findings related to my grandmother’s life and her journey from birth to now. Her marriage to my grandfather at a young age, her journey and those who influenced her ability to cook, and her impact on my family were all effects that I had understood and known during my experiences with my grandmother. In this journey, I learned more about her thoughts and experiences that I never knew before. Our relationship has deepened ten-fold and while she may not be with me forever, I now have a tangible part of her that I can keep with me for the rest of my life.

Description
The novella Flicker by Rachel Ponstein is a climate fiction story. It draws influence from the post-apocalyptic and dystopian genres as well as classic gothic literature. The story utilizes elements of gothic literature including Freud's Uncanny, uneven framing, and bildungsroman. It also utilizes subhuman species to incite conversation about the importance of perspective and the use of an alternative lens on the post-Reckoning world. The disaster story is ambiguous to focus the reader on the importance of the characters and their progress throughout the journey rather than the overall plotline. The analysis below serves as an explanation for the intentional decisions made to fit a sub-genre and engage the reader in an intellectual conversation about the issues broached.
