Preparation for Collegiate Music Theory and Aural Skills Through Repertoire
Music majors often struggle in first-year music theory and aural skills coursework. These struggles have lead to increased dropout rates among music students. Even those students who succeed in music theory course work often are not able to apply theory concepts to music literature. Some universities have identified this problem and sought to rectify it through offering remedial course work, however the universities should not bear this burden. Success in theory and aural skills is linked to mastery of music fundamentals and basic aural skills. Pre-college studies should focus on these subjects and not place too much emphasis on advanced music theory or performance skills alone. Performance studies represent a relevant and readily available platform in which to gain fundamental theory and aural skills. Performance teachers must take the responsibility to purposely integrate music theory and aural skills into their lessons and rehearsals. The ability to put theory into practice contributes to the making of a whole musician. Students studying theory and aural skills through repertoire will gain a more holistic understanding of music and these skills will have practical meaning for the student

Advanced Solar-propelled Cargo Spacecraft for Mars Missions
Three concepts for an unmanned, solar powered, cargo spacecraft for Mars support missions were investigated. These spacecraft are designed to carry a 50,000 kg payload from a low Earth orbit to a low Mars orbit. Each design uses a distinctly different propulsion system: A Solar Radiation Absorption (SRA) system, a Solar-Pumped Laser (SPL) system and a solar powered magnetoplasmadynamic (MPD) arc system. The SRA directly converts solar energy to thermal energy in the propellant through a novel process. In the SPL system, a pair of solar-pumped, multi-megawatt, CO2 lasers in sunsynchronous Earth orbit converts solar energy to laser energy. The MPD system used indium phosphide solar cells to convert sunlight to electricity, which powers the propulsion system. Various orbital transfer options are examined for these concepts. In the SRA system, the mother ship transfers the payload into a very high Earth orbit and a small auxiliary propulsion system boosts the payload into a Hohmann transfer to Mars. The SPL spacecraft and the SPL powered spacecraft return to Earth for subsequent missions. The MPD propelled spacecraft, however, remains at Mars as an orbiting space station. A patched conic approximation was used to determine a heliocentric interplanetary transfer orbit for the MPD propelled spacecraft. All three solar-powered spacecraft use an aerobrake procedure to place the payload into a low Mars parking orbit. The payload delivery times range from 160 days to 873 days (2.39 years)

Shockwave lithotripsy with renoprotective pause is associated with renovascular vasoconstriction in humans
Animal studies have shown that shock wave lithotripsy (SWL) delivered with an initial course of low-energy shocks followed by a pause reduces renal injury. The pause correlates with increased arterial resistive index (RI) during SWL as measured by ultrasound. This suggests that renal vasoconstriction is associated with protecting the kidney from injury. This study explored whether a similar increase in RI is observed in humans. Patients were prospectively recruited from two hospitals. All received an initial dose of 250 lowest energy shocks followed by a two-minute pause. Shock power was then ramped up at the discretion of the physician; shock rate was maintained at 1 Hz. Spectral Doppler velocity measurements were taken from an interlobar artery at baseline after induction, during the pause at 250 shocks, after 750 shocks, after 1500 shocks, and at the end of the procedure. RI was calculated from the peak systolic and end diastolic velocities and a linear mixed-effects model was used to compare RIs. The statistical model accounted for age, gender, laterality, and body mass index (BMI). Measurements were taken from 15 patients. Average RI ± standard deviation pretreatment, after 250 shocks, after 750 shocks, after 1500 shocks, and post treatment was 0.68 ± 0.06, 0.71 ± 0.07, 0.73 ± 0.06, 0.75 ± 0.07 and 0.75 ± 0.06, respectively. RI was found to be significantly higher after 250 shocks compared to pretreatment (p = 0.04). RI did not correlate with age, gender, BMI, or treatment side. This is suggestive that allowing a pause for renal vascular vasoconstriction to develop may be beneficial, and can be monitored for during SWL, providing real-time feedback as to when the kidney is protected
Level of Satisfaction Among Food Pantry Clients, Staff/Volunteers, and Directors and its Association with Client Choice in Food Pantry Layouts
Objectives: Food insecurity is an issue in rural communities, particularly among food pantry clients. Food pantries may not provide clients with the opportunity to choose their own foods (client choice), and instead may just give a set amount and type of foods. Client choice is important in regards to client health status as well as perceptions of autonomy and quality of life. Although client choice can be promoted in food pantries, it may be difficult to grasp the process of food pantry transitioning and how well changes such as these may be perceived by clients or food pantry personnel. We sought to determine the association between client choice within pantries and perceptions of food pantry client, staff/volunteer, and director in six Midwestern states. Methods: Degree of client choice within the pantry was determined using a study-developed MyChoice scorecard, which could range in score from 0 to 42. Change in MyChoice score from baseline to post-intervention (follow-up) was calculated. 191 rural food pantry clients completed baseline and follow-up data collection and were surveyed on their levels of satisfaction with amount, variety and choice of foods received from their food pantry. Differences in pre/post satisfaction scores were calculated and linear regression was used to determine the relationship between change in satisfaction score and change in MyChoice score while controlling for intervention status, sex and age. Additionally, 101 food pantry staff and volunteers and 41 food pantry directors were surveyed on their perceptions related to how food was displayed and distributed. Perception responses were dichotomized and logistic regression was used to determine the relationship between these outcomes and MyChoice score while controlling for intervention status, sex and age. Odds ratios and p-values are reported. Results: MyChoice observation scores improved over the course of the intervention (8.4±8.1). Overall changes within food pantries, as indicated by increases in choice scores, were positively perceived by pantry clients, staff/volunteers, and directors. Increases in client satisfaction with increases in MyChoice score were seen for amount (p=.041) and variety (p=.008) but not choice (p=.077). For pantry staff/volunteers, odds of reporting changes to the way foods were displayed and changes to the way foods were given out increased with increasing MyChoice score (both OR 1.2, pDiscussion and Conclusion: Satisfaction among pantry clients, staff/volunteers, and directors is not negatively impacted by the switch from less choice to more choice in food pantries, so this should not be a discouragement in making changes to improve client choice
