ABSTRACT
Asthma is a high-stress, chronic medical condition; 1 in 12 adults in the United States combat the bronchoconstriction from asthma. However, there are very few strong studies indicating any alternative therapy for asthmatics, particularly following a cold incidence. Vitamin C has been proven to be effective for other high-stress populations, but the asthmatic population has not yet been trialed. This study examined the effectiveness of vitamin C supplementation during the cold season on cold incidence and asthmatic symptoms. Asthmatics, otherwise-healthy, who were non-smokers and non-athletes between the ages of 18 and 55 with low plasma vitamin C concentrations were separated by anthropometrics and vitamin C status into two groups: either vitamin C (500 mg vitamin C capsule consumed twice per day) or control (placebo capsule consumed twice per day). Subjects were instructed to complete the Wisconsin Upper Respiratory Symptom Survey-21 and a short asthma symptoms questionnaire daily along with a shortened vitamin C Food Frequency Questionnaire and physical activity questionnaire weekly for eight weeks. Blood samples were drawn at Week 0 (baseline), Week 4, and Week 8. Compliance was monitored through a calendar check sheet. The vitamin C levels of both groups increased from Week 0 to Week 4, but decreased in the vitamin C group at Week 8. The vitamin C group had a 19% decrease in plasma histamine while the control group had a 53% increase in plasma histamine at the end of the trial, but this was not statistically significant (p>0.05). Total symptoms recorded from WURSS-21 were 129.3±120.7 for the vitamin C and 271.0±293.9, but the difference was not statistically significant (p=0.724). Total asthma symptoms also slightly varied between the groups, but again was not statistically significant (p=0.154). These results were hindered by the low number of subjects recruited. Continued research in this study approach is necessary to definitively reject or accept the potential role of vitamin C in asthma and cold care.

Description
The focus of this in-depth study is to look at the gestation, performance history, and reception of Giacomo Puccini's evening of three one-act operas called Il Trittico and differentiate the particular components, Il Tabarro, Suor Angelica, and Gianni Schicchi to analyze them for their individual stylistic elements of Italian Opera. These were the styles of verismo, pathos and sentimentality, and opera buffa. As substantiated by written criticism, the audience and the critics did not fully comprehend the hidden meaning behind the individual works of Il Trittico. Puccini, enigmatically, had chosen to present one last glimpse of outmoded Italian operatic traditions. In order to evaluate Il Trittico's importance in the history of Italian opera, this study will first review the musically changing landscape in Italy during the early to mid-nineteenth century, then the second part of the nineteenth and beginning of the twentieth-century when German, French, and eventually Russian music were starting to influence audience taste. Puccini who, over the course of his compositional life, absorbed and incorporated these different styles realized that long held Italian operatic tradition had reached a fork in the road. One path would ensure Italian composers a place in this new order and the other a stagnant dead end.
Even though Puccini's triptych garnered primarily negative reviews, the basis for this negativity was the perception that Il Trittico had broken with the historically traditional Italian musical styles. Though the present study acknowledges that break to a degree, it will also present a historically based rationale for the deviation, one left largely unnoticed by Puccini's critics. In the end, this author plans to realize their symbolic importance as a farewell to three uniquely Italian styles and a departure point for a new operatic tradition. Looking forward to the centenary of the work, this author seeks to illuminate how Puccini reached the pinnacle of firmly rooted genres of Italian opera. Ultimately this might help to unravel the enigma of Il Trittico while it continues to secure its rightful place as one of the masterpieces of the Puccini canon.

Description
Students afflicted with music performance anxiety (MPA) can greatly benefit from guidance and mentorship from a music teacher with whom they have established trust, however there exists a knowledge gap between the development and manifestations of MPA, and how it can be overcome in order to prepare the student for success as a performer. It is my purpose with this guide to inform musicians, including students and teachers, about MPA, common coping methods, and outside resources where pedagogues, students, and even professionals can find further guidance. This document is designed to aid music students and teachers in their individual research on the topic. The first section provides necessary background information on MPA and concepts of gender, identity, and personality. A discussion of the results of an experimental protocol that surveyed double reed musicians about their experiences with performance anxiety comprises the second section. An annotated bibliography, listing other resources including self-help books, personal accounts, and scientific studies, is contained in the final section of this guide. Because of the relative absence of research done on the correlation between MPA and specific identity traits including personality, self-image, and gender, it was necessary to incorporate more generalized sources relating to the topic. The annotations offer a more comprehensive approach to understanding and overcoming MPA. This work is not meant to be all-inclusive; rather, its purpose is to act as a basic guide.

Description
Long term high fat diets (HFD) are correlated with the development of diabetes
and kidney disease. However, the impact of short term high fat intake on the etiology of kidney disease has not been well-studied. Therefore, this study examined the impact of a six week HFD (60% fat) on kidney structure and function in young male Sprague-Dawley rats. Previous studies have shown that these animals develop indices of diabetes compared to rats fed a standard rodent chow (5% fat) for six weeks. The hypothesis of this study is that six weeks of HFD will lead to early stages of kidney disease as evidenced by morphological and functional changes in the kidney. Alterations in morphology were determined by measuring structural changes in the kidneys (changes in mass, fatty acid infiltration, and structural damage). Alterations in kidney function were measured by analyzing urinary biomarkers of oxidative RNA/DNA damage, renal tissue lipid peroxidation, urinary markers of impaired kidney function (urinary protein, creatinine, and hydrogen peroxide (H2O2)), markers of inflammation (tumor necrosis factor alpha (TNFα) and interleukin 6 (IL-6)), as well as cystatin C, a plasma biomarker of kidney function. The results of these studies determined that short term HFD intake is not sufficient to induce early stage kidney disease. Beyond increases in renal mass, there were no significant differences between the markers of renal structure and function in the HFD and standard rodent chow-fed rats.

Description
The thrill of a live performance can enhance endorphin, serotonin, dopamine, and adrenaline levels in the body. This mixture of heightened chemical levels is a result of "performance adrenaline." This phenomenon can positively and/or negatively affect a performing singer. A singer's body is her instrument, and therefore, any bodily change can alter the singing voice. The uptake of these chemicals can especially influence a central aspect of singing: breath. "Performance adrenaline" can induce shallow or clavicular breathing, alter phonation, and affect vibrato. To optimize the positive effects and counteract the negative, diaphragmatic breathing, yoga, and beta-blockers are explored as viable management tools. When managed properly, the boost offered by "performance adrenaline" can aid the singer in performing and singing. After a review of medical and psychological studies that reveal the physiological and emotional effects of endorphins, serotonin, dopamine, and adrenaline, this paper will explore the biological changes specific to vocalists and methods to optimize these effects in performance.

Description
"Recontextualizing Music for Social Change" proposes alternative ways through which the traditional setup of a vocal recital may be transformed into a multidisciplinary performance with a specific social purpose. This task might be achieved by the conscious use and merging of elements such as innovation, ritualistic significance of music, and hopes for social change.
Rather than exclusively analyzing the nature of these three elements, this document seeks to exemplify the artistic use of these tools through the description of two doctoral recitals. These performances focus on the portrayal of two specific social issues concerning gender identity: the femme fatale, and sexual identity.
The first performance, "Defatalizing the Femme Fatale: The Voice behind a Stereotype," reflects on the negative connotations of the French femme fatale stereotype. This dangerous image has been perpetuated through popular and mass media since the nineteenth century. The femme fatale has achieved an iconic status thanks to her appealing, damaging, unrealistic, and hypersexualized traits. Nevertheless, this male-constructed stereotype was actually conceived as a parody of female emancipation. "Defatalizing the Femme Fatale" seeks to create awareness of this image through a staged approach of Shostakovich's Michelangelo Suite, feminist poetry and prose, and euphonium music.
The second performance, "Un-Labelling Love: A Scientific Study of Romantic Attachment in Four Seasons," analyses the biological nature of love. According to this perspective, "Un-Labelling Love" transforms a vocal recital into a scientific lecture. This lecture examines four developmental stages of romantic love through the performance of art songs and the inclusion of a narrator, who describes the biological and psychological changes experienced by two research subjects--the performers--during these love stages. Through a plot-twist at the end of the performance, "Un-Labelling Love" also questions the patriarchal assumption that heterosexual kinship represents, by default, the unmarked category of adult pair-bonding. In summary, and based on scientific facts, this vocal performance seeks to encourage social assimilation of non-heterosexual kinship systems.

Description
The common cold is a significant cause of morbidity world-wide, with human rhinovirus infections accounting for a majority colds suffered each year. While the symptoms of the common cold are generally mild and self-limiting, vulnerable populations such as individuals with asthma can experience severe secondary complications including acute asthma exacerbation which can result in severe morbidity. Most human rhinovirus types utilize Intercellular Adhesion Molecule-1 (ICAM-1) as a receptor to enter cells and initiate infection. Expression of this cell-surface protein is elevated in the respiratory tract of asthma patients. The theoretical basis for this research is the observation that plasma measures of the soluble form of Intercellular Adhesion Molecule-1 (sICAM-1) decrease in response to vitamin C supplementation. As rhinovirus infection occurs in the upper respiratory tract, the primary aim of this study was to evaluate change in sICAM-1 concentration in nasal lavage of asthmatic individuals in response to vitamin C supplementation. Otherwise healthy asthmatic adults between the ages of 18-65 years who were not currently using steroidal nasal sprays, smoking, or actively training for competitive sports were recruited from a university community and surrounding area to participate in an 18-day double-blind randomized placebo-controlled supplement study with a parallel arm design. 13 subjects were stratified based on age, gender, BMI and baseline plasma vitamin C level to receive either 500 mg vitamin C twice daily (VTC, n=7) or placebo (PLC, n=6). Biochemical measures included nasal lavage sICAM-1, plasma sICAM-1, plasma histamine, and plasma vitamin C. Survey measures included Wisconsin Upper Respiratory Symptom Survey-21 to assess colds, Daytime Symptom Diary Scale to assess asthma symptoms, and measures of diet quality including a vitamin C food frequency questionnaire and Rapid Eating Assessment for Participants. No between group comparison of means reached significance (Mann-Whitney U test, p>0.05). Nasal lavage sICAM-1 levels were decreased in VTC group by 37% at study day 4, although this finding did not reach significance. Findings in this study can be used to develop future investigations into the response of nasal lavage sICAM-1 to vitamin C supplementation.

Description
Dietary counseling from a registered dietitian has been shown in previous studies to aid in weight loss for those receiving counseling. With the increasing use of smartphone diet/weight loss applications (app), this study sought to investigate if an iPhone diet app providing feedback from a registered dietitian improved weight loss and bio-markers of health. Twenty-four healthy adults who owned iPhones (BMI > 24 kg/m2) completed this trial. Participants were randomly assigned to one of three app groups: the MyDietitian app with daily feedback from a registered dietitian (n=7), the MyDietitian app without feedback (n=7), and the MyPlate feedback control app (n=10). Participants used their respective diet apps daily for 8-weeks while their weight loss, adherence to self-monitoring, blood bio-markers of health, and physical activity were monitored. All of the groups had a significant reduction in waist and hip circumference (p<0.001), a reduction in A1c (p=0.002), an increase in HDL cholesterol levels (p=0.012), and a reduction in calories consumed (p=0.022) over the duration of the trial. Adherence to diet monitoring via the apps did not differ between groups during the study. Body weight did not change during the study for any groups. However, when the participants were divided into low (<50% of days) or high adherence (>50% of days) groups, irrespective of study group, the high adherence group had a significant reduction in weight when compared to the low adherence group (p=0.046). These data suggest that diet apps may be useful tools for self-monitoring and even weight loss, but that the value appears to be the self-monitoring process and not the app specifically.

Description
Bohuslav Martinù (1890-1959) was a prolific composer who wrote nearly 100 works for piano. His highly imaginative and eclectic style blends elements of the Baroque, Impressionism, Twentieth-century idioms and Czech folk music. His music is fresh and appealing to the listener, yet it remains intriguing as to how all the elements are combined in a cohesive manner. Martinù himself provides clues to his compositional process. He believed in pure musical expression and the intensity of the musical idea, without the need for extra-musical or programmatic connotations. He espoused holistic and organic views toward musical perception and composition, at times referring to a work as an "organism." This study examines Martinù's piano style in light of his many diverse influences and personal philosophy. The first portion of this paper discusses Martinù's overall style through several piano miniatures written throughout his career. It takes into consideration the composer's personal background, musical influences and aesthetic convictions. The second portion focuses specifically on Martinù's first large-scale work for piano, the Fantasie et Toccata, H. 281. Written during a time in which Martinù was black-listed by the Nazis and forced to flee Europe, this piece bears witness to the chaotic events of WWII through its complexity and intensity of character. The discussion and analysis of the Fantasie et Toccata intends to serve as a guide to interpretation for the performer or listener and also seeks to promote the piano music of Bohuslav Martinù to a wider audience.

Description
Works for clarinet in the twentieth century exist in abundance; furthermore, the number of extant works from the Classical period is substantial. However, works for solo clarinet in the late-Romantic style are lacking; most of the significant literature for clarinet is contained in orchestral works. Therefore, the purpose of this project is to add to the solo clarinet repertoire of the late Romantic-style through the transcription of works written originally for viola. The four works transcribed for this project are by York Bowen. Bowen was a British composer and pianist who taught at the Royal Academy of Music in England. Although his career flourished in the twentieth century, his music reflects the music of the late-Romantic style. The project includes a transcription of Bowen's Sonata No. 1 in C minor, Op. 18 for viola and piano, Sonata No. 2 in F major, Op. 22 for viola and piano, Romance in D-flat for viola and piano, and Phantasy in F, Op. 54 for viola and piano. Additionally, a brief examination of Bowen's life, an overview of each piece, details regarding transcription parts, a list of changes made to the original part, and a recording of each transcription is included in the document.
