abstract: Throughout history composers have used music to depict their perception of the refugee experience. This project expands upon this idea through the commission and recording of four new works for saxophone. The compositions are Different Arks for solo alto saxophone by John Secunde, Rubble/Resolve for alto saxophone and piano by Jared Yackiw, Emerging Light for soprano saxophone and vibraphone by Alan Hankers, and Unam aeternam for solo alto saxophone and stereo playback by Ashlee Busch. For each work, this project provides performance guides, biographical contexts, program notes, and recordings. I hope to encourage artists to discover and facilitate creative ways to draw attention to migration around the world and contribute to the fight against racism and xenophobia. / Dissertation/Thesis / Doctoral Dissertation Music 2020

In order to establish the rules and criteria· to be satisfied in order to develop a scale model, which may be employed to predict the dynamic behaviour of a fullscale rope-guide mineshaft installation, the theory of the dynamic behaviour of rope-guides is considered. In order to establish to what degree a scale model rope-guide system may be expected to simulate the dynamic behaviour of its fullscale prototype a series of correlation test on an existing rope-guide installation and its dynamic scale model are described. A further series of model investigations into the aerodynamic scale effects which may occur in rope-guide installations, are also described. These investigations demonstrate certain limitations in the use of dynamic scale models of rope-guides and also explain the mechanism of air flow in shaftscontaining bluff bodies. On the strength of the experience gained in this research recommendations are made for the execution of efficient experimental investigations into the dynamic behaviour of various rope-guide mineshaft installations. 6ome information is also provided on the actual design of fullscale rope-guide systems. / Thesis (PhD)--University of Pretoria, 1965. / gm2014 / Mechanical and Aeronautical Engineering / unrestricted

The intent of this dissertation is to provide a reference guide for any prospective performer of Alec Wilder's four works for marimba: Suite for Solo Guitar (1976), Suite for Trumpet and Marimba (1977), Suite for Flute and Marimba (1977), and Sextet for Marimba and Wind Quintet (1977). The first part of the dissertation provides background information pertaining to Wilder himself, the works for marimba, and theoretical aspects of Wilder's music. The second part addresses specific performance problems contained in the music. The dissertation culminates with the presentation of a performance edition of the marimba part of the previously unedited Sextet. This dissertation will facilitate and enhance future performances of these works. It is hoped that this document will serve to help perpetuate and sustain interest in these important compositions.

User Experience (UX) design is the process of creating products that adequately meet users’ needs and result in user satisfaction. In the context of software development, the application of UX design practices has been linked to increased profitability in organisations. Despite the financial benefit organisations stand to gain by adopting UX design practices, previous studies have revealed a low rate of adoption. One key source of resistance to the adoption UX design practices is the perception that adding new steps to an organisation’s software development process would prolong delivery timelines unnecessarily. Such resistance is compounded by the fact that a high proportion of software development projects already exceed their planned durations. The question therefore arises on how the UX design process can be optimised so that it has the least amount of impact on the speed of delivering software. It is this very question that this study answers. In this study, the UX design processes from four case study organisations and six prominent international UX design approaches were reviewed and analysed. From these analyses, commonalities and optimisation opportunities were identified for each process, then synthesised into a proposed framework. This study’s contribution to the Human-Computer Interaction body of knowledge is the proposed Graduated UX Design Adoption (gUXa) framework. The Innovation Resistance Theory (IRT) was used to explain the ability of the gUXa framework to reduce the barrier to UX process adoption due to its potential to optimise the design process for timeous systems development. / Dissertation (MCom)--University of Pretoria, 2020. / Informatics / MCom / Unrestricted

Objective: To determine the association between the perception of practical advice and the educational messages of the food guides in students of a private university in Peru. Methodology: Cross-sectional study. The population corresponded to undergrads who are from the first to tenth semester of their degrees in a private university of Lima-Peru. The sample was 480 university students who voluntarily agreed to participate in the study. The data were collected in the period from october to november of the year 2019. A questionnaire was applied to collect the perception of university students about the messages of the dietary guidelines and the media where they would like to know information about educational messages. Results: 46.5% correspond to undergrads of the Faculty of Health Sciences. Messages 1, 3, 4, 6, 9 and 11 of the Peruvian GABAS showed an evident statistical association (p <0.05). The media with the highest proportion by which they would like to know educational messages about healthy eating were Television (28.5%), Instagram (27.7%) and Facebook (19.0%). Conclusion: Differentiated advertising should be designed and implemented on television, Instagram and Facebook on healthy eating to contribute to the improvement of the health and nutrition status of Peruvian university students.

The purpose of this study was to examine the relationship between job performance of wilderness and adventure therapy (WAT) field guides and personality traits. Specifically, this study utilized the NEO-PI-R to assess personality and the Field Guide Performance Evaluation (FGPE) to assess job performance. Job performance was measured by managers, peers, and WAT participants. The sample consisted of 89 personality assessments, gathered from both the U.S. and Canada. Ordinary least squares regression analysis indicated there was a non-significant relationship between field guide job performance and personality. Findings provide implications for WAT practitioners seeking the most qualified field guides possible.

Anthony Plog (b. 1947) has contributed several notable works for brass instruments. He is known for writing extremely technically challenging works that contain angular melodies, fast rhythms and a large degree of chromaticism. Though his music is difficult, it also conveys intense emotions. His music for trumpet, specifically Concerto no. 1 for Trumpet, Brass Ensemble and Percussion and Concerto no. 2 for Trumpet and Orchestra, represents a zenith in his compositional development. This dissertation examines Concerto no. 1 and Concerto no. 2 from a performer’s perspective to better understand the stylistic characteristics and challenges encountered in his music. Each concerto is examined in terms of rhythmic structure, intervallic structure, thematic material, motivic material and form.

This document aims to add diversity to advanced violin repertoire being taught and performed. Specifically, this project revives late German Romantic composer Robert Kahn (1865-1951) and argues for his violin sonatas to be included in standard violin repertoire due to their immense pedagogical wealth. Kahn was a prolific composer and left behind a large collection of pieces including twenty-five chamber works, the majority involving string instruments. Yet Kahn is rarely performed and hardly known to modern violinists. His works embody the late Romantic style in their expression, harmony, form, and drama and deserve renewed recognition. This document narrows its focus to Kahn's Violin Sonata No. 1 in G Minor, Op. 5 and provides an extensive pedagogical guide for violinists. The guide includes chapters on both collaborative and technical challenges that exist within this piece. The collaborative chapter offers guidance and suggested rehearsal techniques for both instruments regarding balance challenges throughout the first movement. The technical chapter provides exercises for violinists on how to approach several difficult passages within the first and third movements. This project includes an interview conducted by the author with Julia Bushkova and Arsentiy Kharitonov, the first artists to record all three Kahn Sonatas. The transcript of this interview is included in Appendix B of this document.
