This study investigated the effect of environmental heat stress on physiological and performance measures during a ~4 mi time trial (TT) mountain hike in the Phoenix metropolitan area. Participants (n = 12; 7M/5F; age 21.6 ± 2.47 [SD]) climbed ‘A’ mountain (~1 mi) four times on a hot day (HOT; wet bulb globe temperature [WBGT] = 31.6°C) and again on a moderate day (MOD; WBGT = 19.0°C). Physiological and performance measures were made before and throughout the course of each hike. Mean pre-hike hydration status (urine specific gravity [USG]) indicated that participants began both HOT and MOD trials in a euhydrated state (1.016 ± 0.010 and 1.010 ± 0.008, respectively) and means did not differ significantly between trials (p = .085). Time trial performance was impaired by -11% (11.1 minutes) in the HOT trial (105 ± 21.7 min), compared to MOD (93.9 ± 13.1 min) (p = .013). Peak core temperatures were significantly higher in HOT (38.5 ± 0.36°C) versus MOD (38.0 ± 0.30°C) with progressively increasing differences between trials over time (p < .001). Peak ratings of perceived exertion were significantly higher in HOT (14.2 ± 2.38) compared to MOD (11.9 ± 2.02) (p = .007). Relative intensity (percent of age-predicted maximal heart rate [HR]), estimated absolute intensity (metabolic equivalents [METs]), and estimated energy expenditure (MET-h) were all increased in HOT, but not significantly so. The HOT condition reduced predicted maximal aerobic capacity (CRFp) by 6% (p = .026). Sweat rates differed significantly between HOT (1.38 ± 0.53 L/h) and MOD (0.84 ± 0.27 L/h) (p = .01). Percent body mass loss (PBML) did not differ significantly between HOT (1.06 ± 0.95%) and MOD (0.98 ± 0.84%) (p = .869). All repeated measures variables showed significant between-subjects effects (p < .05), indicating individual differences in response to test conditions. Heat stress was shown to negatively affect physiological and performance measures in recreational mountain hikers. However, considerable variation exists between individuals, and the degree of physiological and performance impairment is probably due, in part, to differences in aerobic fitness and acclimatization status rather than pre- or during-performance hydration status.

My Father, My Martyr, and Me: Postcolonial Instructions for Loving the Palestinian Body

This performance attempts to decolonize possibilities for love through unarcheology, an invented method intended to re-narrate artifacts "dug up" by institutions of oppressive power and utilized in service of particular ideologies. Through unarcheologies of Sirhan Sirhan, the performer's father, and the performer's own body, the performance offers a critical call for us to examine the ways that colonial logics of criminality, threat, and wrongness always already implicate Palestinian bodies and our relations with them.
Rhetorics of criminality have long been written onto Palestinian bodies. From Dareen Tatour's imprisonment by the state of Israel to the U.S. detaining Adham Hassoun indefinitely as a "security threat", these rhetorics lead to material violence against Palestinians on a global scale, as well as on a discursive and interpersonal level. Communicative work which seeks to decolonize the Palestinian body in its various settings is vital to our survival in literal as well as symbolic ways. From a postcolonial perspective, we cannot extricate the individual from the communal, the local, the national, the global nor the universal. A postcolonial understanding of "survival" demands that we reflexively interrogate the Palestinian body in its sociohistorical complexity and on its own terms.
Autoethnography is uniquely situated as a method for postcolonial analyses of Palestinian survival. Chawla and Atay argue, "postcolonialism and autoethnography are inherently self-reflexive practices… that necessitate a centering of both the subject–object within a local and historical context" (4). In this performance, I introduce "unarcheology" as a postcolonial method for learning to love the Palestinian body. Using media and embodied performance, I stage a series of scripts comprised of poetic autoethnographic reflection, repurposed diary entries from an archetypal Palestinian "criminal," and the text of my father's indictment. These scripts, composed through a queer, collage-like method I call "unarcheology," are separated into temporal sections (past, present, and future) and audience members determine the order of their performance, thus demanding direct engagement in the performance's decolonial project. Staged on and around a single pile of dirt, this performance interrogates colonial barriers of criminality preventing the capacity to critically love Palestinians. It documents the survival that Palestinians are forced to embody- its goal, however, is the pursuit of critical, generous, decolonized love.

“Mierda.” was an original 50-minute solo dance and theater performance by Jordan Klitzke along with guest artist Gina Jurek that premiered from September 6-8, 2018 at Arizona State University. The creative tools of sensation, presence, and fantasy were applied in the development of an individualized movement vocabulary focused on the artist’s embodiment of contrasting ideas. That research was then further cultivated into an immersive theatrical collage that stimulated relational thinking and heightened consciousness. “Mierda.” was an example of a contemporary creative process that utilized the languages of dance and theater. The performance was a unique continuation of artistic research undertaken by pioneers in the dance and theater fields such as Danielle Agami, Lloyd Newson, Hofesh Schechter, and Anne Bogart. It was documented and created over a nine-month period including the three final performances. The form and content of “Mierda.” was not predetermined, but emerged throughout the creative process and performance of the work. The resulting narrative demonstrated the revelatory potential of this style of theatrical inquiry. Precise energy, tension and questioning formed an immersive, intimate experience for the viewers and performers and invited the audience to “fill in the blanks” as they connected with the emerging narrative. The final work was a collage of surprising juxtapositions on both the micro-level of individual movements and the macro-level of theatrical structure. Analysis of the work resulted in a critical understanding of the creative tools used along with future proposals for continued research. Not only did the research enlighten and contextualize the practices of an emerging choreographer, it also argued for a new understanding of the value of Dance as a personal practice of reflection and growth.

The purpose of this mixed methods case study was to evaluate a dramatic arts curriculum focused on building protective factors including resiliency, cognitive flexibility, self-efficacy, and hope in eight to ten adolescent male sex offenders undergoing treatment at a residential behavioral health facility in Mesa, Arizona. The impetus for this research was suicide prevention efforts. Suicide is the second leading cause of death for ages 15-24 in the United States (CDC 2013), and prevention efforts demand complex approaches targeting major risk factors like lack of belonging and hopelessness. Arts-based prevention efforts have shown promise for building pro-social preventative factors.

Analysis of current electric pickup technology utilized in clarinet performance and investigation into potential improvements

156401-Thumbnail Image.png
Description
Despite the growth of technology in music composition and performance, professional clarinetists maintain that air microphones are superior to piezoelectric pickups. Pickups offer increased mobility, isolation, and reduced feedback, but air microphones are used simply for the perceived sound quality.

Despite the growth of technology in music composition and performance, professional clarinetists maintain that air microphones are superior to piezoelectric pickups. Pickups offer increased mobility, isolation, and reduced feedback, but air microphones are used simply for the perceived sound quality. In this study a ported barrel pickup and a contact transducer pickup placed at various intervals on the clarinet were sampled and compared to a reference recording to determine how the sound differed for each method. In addition, the history of wind instrument pickups, the acoustics of the clarinet, and the basics of piezoelectricity were discussed to help examine the results. The pickups were examined in three ways: overall level in decibels, frequency cutoff, and overtone displacement. Through these results it was determined that the most accurate methods of clarinet pickup are the ported barrel pickup, contact transducers closer to the vibration of the reed such as the ligature or barrel surface, or a transducer placed at the end of the bell. These findings were consistent with the discussions regarding history, clarinet acoustics, and piezoelectricity. This study also produced a reference for the sounds associated with different pickup methods, as well as possible improvements for clarinet pickup design.

Building bridges through music: a recording and performance collaboration with adult composers, young soloists, and collegiate band accompaniment

Although music is regarded as a universal language, it is rare to find musicians of different ages, ability levels, and backgrounds interacting with each other in collaborative performances. There is a dearth of mixed-ability-level wind band and string orchestra repertoire, and the few pieces that exist fail to celebrate the talents of the youngest and least-experienced performers. Composers writing music for school-age ensembles have also been excluded from the collaborative process, rarely communicating with the young musicians for whom they are writing.

This project introduced twenty-nine compositions into the wind band and string orchestra repertoire via a collaboration that engaged multiple constituencies. Students of wind and string instruments from Phoenix’s El Sistema-inspired Harmony Project and the Tijuana-based Niños de La Guadalupana Villa Del Campo worked together with students at Arizona State University and composers from Canada, Finland, and across the United States to learn and record concertos for novice-level soloists with intermediate-level accompaniment ensembles.

This project was influenced by the intergenerational ensembles common in Finnish music institutes. The author provides a document which includes a survey of the existing concerto repertoire for wind bands and previous intergenerational and multicultural studies in the field of music. The author then presents each of the mixed-ability concertos created and recorded in this project and offers biographical information on the composers. Finally, the author reflects upon qualitative surveys completed by the project’s participants.

Most the new concertos are available to the public. This music can be useful in the development and implementation of similar collaborations of musicians of all ages and abilities.

A study of the piano works by Anatol Lyadov

As one of the composers living in an era filled with innovations, Anatol Konstantinovich Lyadov (1855-1914) has been relatively ignored by scholars and pianists to date. He is an unusual composer with multiple characteristics: solitary but expressive, talented but indolent. His compositional style never lacked critics—especially with respect to his persistent preference of miniatures. Nonetheless, his piano works embody the breathtaking beauty of the composer’s independent musical ideas and colorful musical language. Compared with the flourishing, dazzling, and nationalized music from other composers living in the same era, these light, flowing musical pieces from Lyadov have irreplaceable value.

Through the study of these small-scale piano works, one finds important connections with the music of other renowned composers (e.g. Chopin and Scriabin), and the employment of traditional aspects such as Russian folk tones and fairy tales. Stylistically, Lyadov was a representative of 19th-century Romanticism; however, his compositional style changed during his late period (after 1900), presenting a unique use of dissonance.

The scholarly research on Lyadov’s piano works remains limited. Most of the related resources can be found only in the Russian music literature. No in-depth study or dissertation on the complete piano works of Lyadov could be located, and therefore my research paper is intended to provide useful information to piano performers and teachers, hopefully encouraging more study and performance of Lyadov’s piano works. Despite their lyrical melodies and deep emotion, these works are thus far relatively unpopular and unknown, with only a few played occasionally as encore pieces.

This study used an online survey methodology looking at all levels of archers and coaches to understand their perceptions of the shooting process and Mental Game importance. The survey asked about the archer's skill level and their training style, as well as their perception of the importance of each step in the shooting process and the different parts of the Mental Game. The study also processed the impact of performance of an archer based on their perception of importance of the different steps of the shooting process and the Mental Game. Depending on if the archer has ever had a coach, certain steps of the shooting process and certain parts of the Mental Game was impacted by having a coach at one time. While, the level of coach also impacts how the Mental Game is perceived. Throughout this study, imagery was the most impacted by the level of coach the participant is, if the participants have ever had a coach, and how the participants perform.

The Cello as a Voice of Humanity - Bach and Kodaly: An Exploration/Recital

Description
This thesis explores the musical and historical aspects of two of the greatest solo works for the cello: Suite No. 6 in D major, BWV 1012 by Johann Sebastian Bach and the Sonata for Solo Cello, Op. 8 by Zoltán

This thesis explores the musical and historical aspects of two of the greatest solo works for the cello: Suite No. 6 in D major, BWV 1012 by Johann Sebastian Bach and the Sonata for Solo Cello, Op. 8 by Zoltán Kodály. The thesis and creative project consists of a researched paper of approximately 30 pages of historical and musical analysis on both pieces and the “defense” was a recital where I performed both pieces memorized with an informed approach. Part I explores of Bach’s Suite No. 6 in D major, BWV 1012, and Section 1 includes a biography and historical context during the period in which the sixth suite was written. Section 2 consists of an analysis of all six movements (Prelude-Allemande-Courante-Sarabande-Gavottes I and II-Gigue). The analysis explores the German dance form of the suite movements and how they are relevant to the sixth suite, as well as musical aspects that make the sixth suite unique. Part II explores Kodály’s Sonata for Solo Cello, Op. 8 that has a similar structure as Part I with a Section 1 of biography and historical context during the period of the sonata, and a Section 2 analysis. Section 1 explores Kodály’s life and studies in folk music that is relevant to the Sonata, and Section 2 musical analysis with points of relevance to the Hungarian language folk song. The Sonata consists of three lengthy movements (Allegro maestoso ma appassionato-Adagio con grand espressione-Allegro vivace) and the analysis consists of formal, musical, and a few pedagogical approaches. The thesis is rounded out with a conclusion of personal reflection added during the revision process. This musical and historical analysis greatly informed my performance of these works and the “defense” recital was highly successful.
