Description
Quantum resilience is a pragmatic theory that allows systems engineers to formally characterize the resilience of systems. As a generalized theory, it not only clarifies resilience in the literature, but also can be applied to all disciplines and domains of discourse. Operationalizing resilience in this manner permits decision-makers to compare and contrast system deployment options for suitability in a variety of environments and allows for consistent treatment of resilience across domains. Systems engineers, whether planning future infrastructures or managing ecosystems, are increasingly asked to deliver resilient systems. Quantum resilience provides a way forward that allows specific resilience requirements to be specified, validated, and verified.
Quantum resilience makes two very important claims. First, resilience cannot be characterized without recognizing both the system and the valued function it provides. Second, resilience is not about disturbances, insults, threats, or perturbations. To avoid crippling infinities, characterization of resilience must be accomplishable without disturbances in mind. In light of this, quantum resilience defines resilience as the extent to which a system delivers its valued functions, and characterizes resilience as a function of system productivity and complexity. System productivity vis-à-vis specified “valued functions” involves (1) the quanta of the valued function delivered, and (2) the number of systems (within the greater system) which deliver it. System complexity is defined structurally and relationally and is a function of a variety of items including (1) system-of-systems hierarchical decomposition, (2) interfaces and connections between systems, and (3) inter-system dependencies.
Among the important features of quantum resilience is that it can be implemented in any system engineering tool that provides sufficient design and specification rigor (i.e., one that supports standards like the Lifecycle and Systems Modeling languages and frameworks like the DoD Architecture Framework). Further, this can be accomplished with minimal software development and has been demonstrated in three model-based system engineering tools, two of which are commercially available, well-respected, and widely used. This pragmatic approach assures transparency and consistency in characterization of resilience in any discipline.

Description
To be a versatile violinist, one needs interdependence of aural, visual and kinesthetic skills. This thesis introduces aural, visual and kinesthetic learning modalities, and explores the way each is used in the Suzuki, Paul Rolland, Orff, Kodály, and Dalcroze methods, as well as in Edwin Gordon’s Musical Learning Theory. Other methods and pedagogical approaches were consulted and influential in developing the curriculum, such as the teaching of Mimi Zweig, but were not included in this paper either because of an overlap with other methods or insufficient comparable material. This paper additionally presents a new curriculum for teaching beginning violin that incorporates aural, visual, and kinesthetic learning in a systematic and comprehensive manner. It also details a sequenced progression to learn new repertoire and develop proficiency with rhythm, solfège, reading and writing musical notation, and left- and right-hand technique.

Description
This thesis proposes an augmentation of the Complete Method for Trombone by Jean Baptiste Arban. Although it is widely considered one of the leading trombone method books in the world, a thorough consideration of the demands of most performed solo literature today reveals serious shortcomings in the Arban Method for preparing trombonists to encounter such demands as meter and rhythm, keys and tonalities, range and endurance, clefs and F-attachment usage. This thesis thus proposes additions for a new version of the Arban Method that better aligns with the playing demands of the most performed solo literature today, as compiled by the International Trombone Association Journal since 1972.

Description
In the 1950s, Miguel Llobet (1878–1938) and Emilio Pujol (1886–1980) published the first transcriptions of piano and orchestral music for two guitars that became staples in the repertoire. Ida Presti (1924–1967) and Alexandre Lagoya (1929–1999) expanded their efforts with new adaptations of Baroque, Romantic, and Modern music. Following their examples, generations of professional guitar duos have maintained a similar transcription repertoire. However, closer examination reveals noticeable gaps in it as Renaissance works have been largely overlooked. To illuminate this issue, chapter 2 revisits adaptations for two guitars of music originally written for vihuelas, lutes, viols, and the virginal to inquire about the reasons for this neglect and discuss plausible solutions. Because the virginal stands out for its innovative characteristics and alignment with the solo lute works by John Dowland (1563–1626) and John Johnson (ca. 1545–1594), the “English School” of Virginalists is further explored as a potential source of suitable works for transcriptions.
Chapter 3 discusses philosophical concepts and editorial practices to propose a method aimed at producing stylistically faithful adaptations of virginal music. The editorial criteria for this method are informed by in-depth reflections on terminology, the ontology of musical works, the notion of authenticity, and common sixteenth-century practices from musica ficta to tuning temperaments and notational conventions. Concerning ethical matters, this chapter assesses authorship issues that originated at the turn of the nineteenth century but are still adopted by modern editors and transcribers. This discussion aims to shed light on both the negative impact on intellectual property and how it can be avoided by simply resorting to the practice of scholarly transcriptions. Chapters 4 and 5 explain the procedures and applications of the proposed method in two parts: adaptation and revision. The first introduces concepts and strategies from choosing suitable works to balancing playability and aesthetic fidelity intended to produce a preliminary version of the original work. The second establishes a knowledge base through musico-historical discussions and comparative analyses of sources that inform editorial decisions and necessary changes to be implemented in the final score.

Description
This paper will highlight the ways that Chinese students handle stress due to different reasons and how they solve their stress. The main reasons include different education styles, cultural differences between the US and China, food, language, entertainment ways and religious. Chinese students have many methods to solve stress that include both positive and negative ways. I will provide more details about the ways in the third part in which I report the findings of my survey. My study is relevant because of the large numbers of Chinese students who are studying internationally.

Description
Since its first report in 1976, many outbreaks linked to Legionella have been reported in the world. These outbreaks are a public health concern because of legionellosis, which is found in two forms, Pontiac fever and Legionnaires disease. Legionnaires disease is a type of pneumonia responsible for the majority of the illness in the reported outbreaks of legionellosis. This study consists of an extensive literature review and experimental work on the aerosolization and UV inactivation of E.coli and Legionella under laboratory conditions. The literature review summarizes Legionella general information, occurrence, environmental conditions for its survival, transmission to human, collection and detection methodologies and Legionella disinfection in air and during water treatment processes.
E. coli was used as an surrogate for Legionella in experimentation due to their similar bacterial properties such as size, gram-negative rod-shaped, un-encapsulated and non-spore-forming bacterial cells. The accessibility and non-pathogenicity of E. coli also served as factors for the substitution.
Three methods of bacterial aerosolization were examined, these included an electric spray gun, an air spray gun and a hand-held spray bottle. A set of experiments were performed to examine E. coli aerosolization and transport in the aerosolization chamber (an air tight box) placed in a Biological Safety Cabinet. Spiked sample was sprayed through the opening from one side of the aerosolization chamber using the selected aerosolization methods. The air sampler was placed at the other side to collect 100 L air sample from the aerosolization chamber. A Tryptic Soy Agar plate was placed inside the air sampler to collect and subsequently culture E. coli cells from air. Results showed that the air spray gun has the best capability of aerosolizing bacteria cells under all the conditions examined in this study compared to the other two spray methods. In this study, we provide a practical and efficient method of bacterial aerosolization technique for microbial dispersion in air. The suggested method can be used in future research for microbial dispersion and transmission studies.
A set of experiments were performed to examine UV inactivation of E. coli and Legionella cells in air. Spiked samples were sprayed through the opening from one side of the aerosolization chamber using the air spray gun. A UV-C germicidal lamp inside the Biological Safety Cabinet was turned on after each spray. The air samples were collected as previously described. The application of UV-C for the inactivation of bacterial cells resulted in removing aerosolized E. coli and Legionella cells in air. A 1 log reduction was achieved with 5 seconds UV exposure time while 10 seconds UV exposure resulted in a 2 log bacterial reduction for both bacteria. This study shows the applicability of UV inactivation of pathogenic bacterial cells in air by short UV exposure time. This method may be applicable for the inactivation of Legionella in air ducts by installing germicidal UV lamps for protecting susceptible populations in certain indoor settings such as nursing homes or other community rooms.
