D.Phil. (Personal and Professional Leadership) / For most graduates, entry into the working world is the start of everything they have aimed for through school and university. (Holden & Hamblett, 2007). They arrive with an intense desire to prove themselves, along with often unrealistic expectations of what the organisation will deliver. The organisation, driven by deadlines, profits, and promises to shareholders, has its own aims, and all this is situated “in a time of vast changes – changes so epochal that they may dwarf those experiences in earlier eras… changes that call for new educational forms and processes.” (Gardner, 2006, p.11). Add to this South Africa’s specific issues around quality of education, historical inequalities, and culturally disparate workforces, and you have multiple reasons for why both business and graduates could “fail to achieve their real goals” (Schein, 1964, p. 68). In order to better support graduates, it is necessary to more deeply understand the nature of the graduate transition from university to the world of work. As identity is critical to the process of adapting to new professional roles, I focused on the graduate identity journey in the first year of work (Ibarra, 1999). Using constructivist grounded theory, I tracked a group of 20 graduates over a one-year period, in a graduate development programme in a financial insitiution in Johannesburg, South Africa. Comparing the data I collected to Holmes’s (2001) Claim-affirmation Model of Emergent Identity, I provide insight into the identity issues that graduates need to overcome during this first year, how these issues impact their self-esteem, personal agency, and self-efficacy, and which coping methods they choose to employ during this time. The results suggest that by providing graduates with a liminal temporary identity, the graduate identity, they are better able to manage the transition from student identity to professional identity. The temporary graduate identity allows them to play with their identity rather than work at their identity while on the graduate programme (Ibarra & Petriglieri, 2011). In order to create the temporary graduate identity it is suggested that graduate development programmes need to be reconceptualised as rites of passage, filled with ritualised activities that enable graduates to experience communitas with other graduates on the programme (Turner, 2008). Various graduate rituals are suggested to this end. Within the graduate rite of passage, graduates need to be supported in developing their interpersonal, intrapersonal and technical skills. To help graduates develop deeper insight into self and others, a graduate self development model is proposed. In order to support the development of technical skills, rotational technical skills programmes and fixed role programmes are explored. A framework is suggested for how to develop rotational programmes that maximise the pros and minimise the cons of rotational programmes. In order for the graduate programme managers to best support graduates during their time on the programme I recommend that they need to become more sensitive to the needs of the graduates, I adapt the graduate self development model and offer this as a tool for programme managers self development. This model will help graduate programme managers to begin to uncover some of their own stereotypes and unconcious biases, and more deeply develop their coaching, mentoring and supporting skills. Many of the graduate issues that arise while on the graduate programme involve graduates and managers leaping to conclusions based on faulty assumptions about each other. This often results in an impasse between graduates and their managers. I suggest that graduate programme managers take on the added role of mediator in order to point out to graduates, and their managers, how they might be misconstruing each other, therefore helping to avert some of the issues graduates experience. The findings of this study therefore have implications for graduate programme managers, and provides insight into how to better design and develop future graduate programmes.

Florida is the “Fishing Capital of the World”. With 3.1 million recreational anglers and total recreational fishing-related expenditures of $5 billion in 2011, Florida ranked first in the nation. Given the large benefits of recreational fishing in Florida, assessing the preferences of anglers is critical for sustaining the substantial benefits obtained from recreational fishing in Florida. The objective of this study is to estimate the value of fishing attributes using data on recreational fishing services offered by guides and outfitters. Hedonic price models are applied to estimate the implicit prices of fishing trip attributes and features. The estimated total economic impacts suggest that recreational fishing activities have added $151.19 million value to the economy of Florida and generated $69.73 million in total output. The results can be used by state and national policymakers for future policy design and management of this unique ecosystem service to ensure a sustainable economy.

The Girl Guides of Canada is a youth service organization, serving almost 10% of the Canadian female population aged 5-17, that aims to teach girls and young women to become responsible citizens. In this thesis, I review the curriculum of the Pathfinder branch (for girls and young women aged 12-15) of the Girl Guides of Canada. Using feminist, anti-racist, and queer perspectives, I treat "responsible citizenship" as a discursive concept and conduct a discourse analysis of the Pathfinder programme to discover how it attempts to gain the consent of girls and young women to particular definitions of responsible citizenship. Drawing on feminist citizenship theory developed by Yuval-Davis, Anthias, Alexander, and Ross, I argue that the state implicates select female citizens in nation building practices as biological reproducers and transmitters of culture. I also draw on theories of moral regulation extended by Sangster, Strange, and Loo to illustrate ways in which the state and voluntary organizations attempt to gain the consent of citizens to particular ways of being. I argue that, because its texts authorize particular definitions of responsible citizenship, the Pathfinder curriculum implicates girls and young women in capitalist nation building in Canada. Specifically, I argue that the Pathfinder programme normalizes heterosexuality, whiteness, and ability, and privileges middle-class values. I also demonstrate that a responsible citizen, according to the Pathfinder curriculum, performs caregiving and environmental stewardship as volunteer service, prepares to join the labour force, and is healthy, hygienic, cheerful and obedient. I raise questions about the nature of the organization's efforts to teach about sexism, racism, classism, ableism, homophobia and heterosexism, and suggest some ways in which the curriculum can attend to these social relations to develop a more inclusive image of the ideal responsible citizen. I also suggest a number of directions for future research. / Arts, Faculty of / Anthropology, Department of / Graduate

Nesta tese, nós quebramos esta dependência empregando moléculas fotônicas (Photonic Molecules, PMs) baseadas em múltiplos anéis internamente acoplados a um anel externo, que por sua vez está acoplado a um guia de onda. Aplicando o método de matriz de transferência (Transfer-Matrix Method, TMM) e programas robustos de simulação, nós projetamos três tipos de PMs baseada em uma plataforma de Silício-sobre-isolante (Silicon-on-Insulator, SOI). Este projeto mostrou que o acoplamento entre duas ou mais micro-cavidades ópticas, permite separações espectrais e hibridização dos modos quando as frequências ressonantes estão degeneradas nas cavidades, similar ao acoplamento fraco entre átomos. Estas PMs foram fabricadas com um processo convencional e compatível com a tecnologia CMOS, empregando uma Foundry, e suas caracterizações mostraram a emergência de dupletos, tripletos, quadrupletos e sextupletos de ressonâncias degeneradas, com alto Q e espaçamentos curtos, somente possíveis com anéis de algumas ordens de magnitude maiores em área. Estes resultados quebraram o paradigma da interdependência entre Q, FSR e R, evidenciando que é possível ter tempo de vida fotônico, espaçamento espectral e área independentes. As aplicações destas PMs em processamento de sinal óptico também foram demonstrados neste trabalho. Nós apresentamos o uso da molécula com dupleto de ressonâncias para extrair um sinal RF de 34.2 GHz, filtrando as bandas laterais de um sinal modulado. Também foi demonstrado que moduladores ópticos ultracompactos operando à 2.75 vezes acima do limite da largura de linha do ressonador pode ser obtido a partir da PM que apresenta um tripleto de ressonâncias, separadas de ~55 GHz. Finalmente, utilizando a molécula que permite obter um quadrupleto de ressonâncias, foi demonstrado a conversão de comprimento de onda totalmente óptico (multicasting) para quatro canais convertidos e separados de 40-60 GHz, utilizando apenas 1 mW de potência de controle / Abstract: Photonic systems based on microring resonators have a fundamental constraint given by the strict relationship among free spectral range (FSR), total quality factor (Q) and resonator size (R). In this thesis, we break this dependence employing CMOS compatible photonic molecules (PMs) based on multiple inner ring resonators coupled to an outer ring, which is coupled to a straight bus waveguide. Applying the transfer matrix method (TMM) and simulation robust programs, we project three types of PM based on scalable silicon-on-insulator (SOI) platform. This project shows that the coupling between two or more optical micro-cavities, allows spectral splitting and hybridization of the modes when the resonant frequencies are degenerated in the cavities, similar to weak coupling between atoms. These PMs were fabricated in a conventional CMOS Foundry and your characterization shows the emergence of doublet, triplet, quadruplet and sextuplet of degenerated resonances, with high-Q and close-spaced, only achievable with single-ring orders of magnitude larger in footprint. These results break the paradigm of the interdependence between Q, FSR and R, evidencing that is possible to have photonic lifetime, spectral spacing and footprint independents. The applications of these PMs in optical processing signal were also demonstrate in this work. We demonstrate the use of the doublet splitting for 34.2 GHz RF signal extraction by filtering the sidebands of a modulated optical signal. We also demonstrate that very compact optical modulators operating 2.75 times beyond its resonator linewidth limit may be obtained using the PM triplet splitting, with separation of ~ 55 GHz. Finally, using the quadruplet of resonances, we demonstrate four-channel all-optical wavelength multicasting using only 1 mW of control power, with converted channel spacing of 40-60 GHz / Doutorado / Física / Doutor em Ciências

The analysis method adopted is the moment method in junction with the image method. Discontinuities formed by a single vertivcal post, vetical posts with a central gap, horizontal posts with a central gap, and posts on the four waveguides walls are analyzed. The results are compared with experimental data for the four geometries described above. Moreover the results are also compared with those obtained by variational method in the case of the single vertical post.

Light guide is a tubular skylight with mirrored internal surface. It is a lighting device bringing daylight into the interior of a building without windows or into rooms with insufficient daylight. It presents the potential for energy savings, opens the possibility to use places that are not well lit and offers opportunities for improving the visual comfort of the indoor environment. This thesis reviews the potential of light guide system as a daylighting approach in building and presents results of experiments on performance of tubular skylight prototype. The main task of the thesis is focused on comparison of traditional light guide system and newly developed prototype, examination of its light transmittance and efficiency as well as its thermal behaviour in order to find possible improvements for applications in buildings.

Les micro-résonateurs (MRs) sont devenus des éléments clés de la conception de capteurs optiques intégrés, car étant plus miniaturisés que l’existant, ils s’intègrent mieux dans des systèmes ''lab-on-chip'', ce qui permet aussi de réduire le volume des molécules à détecter. Les MRs sont de plus très sensibles à la variation d’indice effectif provoquée par la présence de molécules dans le milieu de détection. Dans cette thèse, nous avons utilisé deux types de matériaux différents: les polymères et le silicium poreux. Les polymères, facilement réalisables avec des méthodes de fabrication peu onéreuses, sont dans un premier temps utilisés pour valider les outils de simulation développés pour l’étude des caractéristiques des MRs pour l’application capteur basée sur la détection par évanescence. Le silicium poreux permet d'exploiter un autre mode de détection, la détection en volume. Les molécules présentes dans le milieu de détection s'infiltrent dans le matériau et réagissent de manière directe avec la lumière. En utilisant les outils de simulation développés et en adaptant le procédé de photolithographie classique utilisé pour la fabrication de MRs en polymères, des premiers MRs constitués de guides ridges à base de silicium poreux sont mis en œuvre et caractérisés. Ces travaux de thèse démontrent expérimentalement la possibilité de détecter des concentrations de glucose avec une meilleure sensibilité que l'état de l'art pouvant atteindre les 600 nm/RIU, pour les domaines utilisant la détection et l'analyse de molécules (santé-agro, défense-sécurité, environnement). / Micro-resonators have become key element for integrated optical sensor because they offer the advantage of significantly minimizing the device size, which allows an easily integration on lab-on-chip and greatly reduces the amount of molecules to be detected. Moreover, micro-resonators are extremely sensitive to the effective index variation induced by the presence of molecules in the detection medium. The thesis focuses on two different materials: polymers and porous silicon. Firstly, polymers, easily implementable with a low cost fabrication, are used to validate the simulation tools developed for the study of micro-resonators characteristics in order to perform sensing application based on the detection by evanescence. Then, porous silicon is investigated in order to operate another type of detection, the detection by volume. The molecules to be detected and present in the medium detection infiltrate into the material and interact directly with the light. Using simulation tools and by adapting the photolithographic process used for polymers micro-resonators fabrication, the first micro-resonators based on porous silicon ridge waveguides are obtained and characterized. The work contained in this thesis demonstrate experimentally the possibility of sensing concentrations of glucose with a sensitivity of 600 nm/RIU, using volume detection, which is higher than the state of the art, for domains using the sensing and analysis of molecules (health, food industries, security and environment).

abstract: In the fast-paced, technology-driven society of today, new demands are placed on artists to re-think how music is presented and communicated to the world. Access to the internet, development of sound manipulation software, and broader means of use and distribution through the digital music industry have drastically shifted the way the twenty-first century artist creates and performs music. One of the most striking changes that occurred is the increased use of visual material as a vehicle to enhance and contribute to the depth and intrigue of live performances and recordings. This project researches twenty-first century works for clarinet and multimedia that specifically include a visual element (including but not limited to images, fixed and interactive video, light effects, and choreography) and highlights the prevalence of this genre in contemporary repertoire. Discussion begins with a brief overview of the history of multimedia, its relation to the clarinet, and how it has been defined by the twenty-first century. Additionally, in order to contribute to this ever-growing repertoire, three new works for clarinet and multimedia were commissioned in collaboration with composers and visual artists. These new works include: Roadrunner (2019) for clarinet and fixed electronics by Spencer Brand with video by Samuel Proctor; I’d known this place (2020) for clarinet and electronics by Dan Caputo with live audio generative animations by Andrew Robinson; and Spectral Passages (2020) for clarinet and electronics by Alvaro Varas with painting by Miguel Godoy. Background information and performance guides are included for each piece to aid future musicians in performance, as well as respective audio/video recordings. Finally, a significant portion of this document includes a catalog of works for clarinet and multimedia. The catalog was compiled by focusing on the output of twenty-first century composers to serve as a resource for future performers. / Dissertation/Thesis / Roadrunner for clarinet and electronics by Spencer Brand / Spectral Passages for clarinet and electronics by Alvaro Varas / I'd known this place for clarinet and electronics by Dan Caputo / Doctoral Dissertation Music 2020

Reference librarians at East Tennessee State University's Sherrod Library identified LibGuides as an efficient way to introduce undergraduate students, particularly those in their first two years of college, to the university library. Selecting pertinent library resources based on a course syllabus and creating a LibGuide for the course provides the students with a limited number of relevant materials. Librarians and professors view the use of subject guides attached to a course management system site as an effective educational solution. Librarians facing exponentially expanding resources and first-year students who are used to turning to Google for all their information needs can utilize LibGuides to guide students toward more relevant library resources.

Tour guides are often required to be a certain version of themselves while selling a particular state of mind to their guests. The job and its lifestyle suggest many influences on tour guides’ identities. Guiding involves working in an emotional environment, representing different groups simultaneously, wearing different ‘masks’ throughout a given working day, and living a unique lifestyle. By interviewing international guides leading active, multi-day, luxury trips, this study explores a broad range of factors that might influence their identity. It analyzed how their work context relates to their idea and sense of self, mainly as a tour guide but also what that means to their perceived place in the world as a person. The study found that the guides highly value the human connections in their job, and they have a strong sense of belonging to their co-leader community. They identify as separate from society by living a peculiar, dynamic, and challenging lifestyle, avoiding settling down. Moreover, they see themselves as socially competent, and they derive purpose and meaning from the job by assuming different roles that make a positive difference for the guests they encounter. The life satisfaction, self-esteem, and confidence that emerges is so gratifying that to a certain extent they forgive the unsustainable practices of their employer. However, the exposure to negative environmental impacts brings about many negative emotions, and even though they try, the minimal impact they individually have on reducing these impacts bothers them and negatively influences their well-being.
