Deciphering grape genomics and the yeast fermentation process is giving Hennie van Vuuren and Steven Lund clues on how to help wineries improve wine quality.

In British Columbia (BC) foresters registered with the Association of BC Forest Professionals (ABCFP) have been given the exclusive right to practise professional forestry. As with all professions there is an expectation that Registered Professional Foresters (RPFs) conduct their activities in an ethical manner and are therefore obligated to act as an ethical agent on behalf of society regarding forest resources. If a certain level of ethical agency is desired of professionals we need to understand whether or not an RPF possesses the ability (defined as their discretion) to sufficiently fulfil this responsibility. Rule-based and principle-based standards of forest management, an RPF’s scope of practice, and the socio-political framework of public forest management in BC all come together to define an RPF’s discretionary context, which sets the limits to an RPF’s discretion. This context is highly idiosyncratic to a specific situation or decision and this makes the RPF’s discretion similarly idiosyncratic. This suggests that an RPF should not be accountable for a standard of ethical agency that does not reflect the context-dependent level of discretion they possess. Fifteen interviews of RPFs were conducted for this study to discuss their approach to ethical decision making. The analysis of the interviews revealed 12 major themes, several of which appear to be highly idiosyncratic to the situations described by the participants. The way these themes were perceived by the participants revealed the differences in the discretionary context of their situations. Several aspects of ethical deliberation emerged from the data that appear to be particular to broad employer categories, including delegated decision-making (government), economic and forest health considerations (industry), and the tension between personal and professional values (consultants).

The purpose of this autoethnographic study was to examine three questions: (a) how did my view of myself as a non-Aboriginal educator change as a result of teaching in an Aboriginal cultural context, (b) how did my teaching philosophy and pedagogical approach change as a result of teaching in an Aboriginal cultural context, and (c) how did my sense of community and relatedness to the people I interacted with change due to increased cultural awareness and exposure to Aboriginal cultures? Data from my time in my teacher education program and teaching in Klemtu, BC was collected, and Mezirow’s (1997) transformative learning theory was used to analyze the shift that I made in these three areas. Finally, recommendations were made to teacher education programs and future non-Aboriginal educators who choose to teach in Aboriginal-run schools.

Students of colonialism know well that the stories we tell have the capacity to make, maintain, or transform our relationships as well as our material futures. As earlier work has shown, Indigenous and settler peoples encountered and apprehended one another through story at first contact and in all subsequent contact moments, reaching right up to present-day mechanisms for negotiating conflicts over rights, resources, sovereignty, and historical injustice. In this dissertation, I explore in depth the role of story as a social practice in Indigenous-state relations, examining a series of key encounters over the last 150 years in which Indigenous peoples challenged and contested the state’s possession of their lands in what would become British Columbia. Informed by archival and community-based research with two Indigenous nations – the Stó:lō and the Haida – this study offers a history of Indigenous tactics in pursuit of the larger objective of decolonization, especially since the 1960s. Each of the four main chapters explores how Indigenous peoples have engaged distinct state-sanctioned mechanisms for addressing the state’s dispossession of their lands. The first chapter examines the dynamics of orality and literacy in a series of Stó:lō petitions from the late nineteenth century, a time when reserves were being reduced in order to accommodate a rapid influx of settlers seeking agricultural lands. Chapter 2 looks at Stó:lō experiences of treaty negotiation in the early twenty-first century, and how they are attempting to re-write the master narrative of Stó:lō -state relations. Chapter 3 focuses on the Haida blockade of logging in the mid-1980s, examining how the Haida acted into being what would become an iconic story of Haida nationhood. Finally, chapter 5 explores story and belief through a close study of the narrative dynamics of Haida participation in the Joint Review of the Enbridge Northern Gateway Project between 2012-2014. In each of these encounters, Stó:lō and Haida people exceed the limited narrative spaces they are assigned for communicating who they are and how they relate to their territories and to the state, while attempting to shift the established narrative. Recent scholarship on Indigenous-state relations has focused on how liberal settler states continue to exclude Indigenous peoples even through their gestures at including them into the body politic. While such work on the state is critical, I suggest that it is equally important to understand Indigenous peoples’ demonstrated capacity for collective cultural endurance, and how it exists in tension with the forces acting to assimilate and subsume Indigenous difference within the normative structures of settler society. This study attempts to grasp the nature of this endurance, and demonstrates how narrative is as central to Indigenous peoples’ repossessions of their land as it was to the state’s original dispossession of it. / Graduate / 2018-08-08

La tragédie du quatrième siècle fut considérée depuis l’antiquité comme une phase de décadence du genre tragique. Toutefois, plusieurs spécialistes ont montré qu’il ne s’agissait pas d’un déclin : le théâtre continuait à jouer un rôle important dans la vie culturelle du monde grec. Dans cette thèse nous proposons une nouvelle édition des fragments des poètes tragiques grecs du quatrième siècle, qui furent actifs entre la fin de la guerre du Péloponnèse et la mort d’Alexandre le Grand. L’édition des textes est précédée d’une courte introduction sur chaque poète et suivie de leur apparat critique, leur traduction et des commentaires. Nous proposons également un nouvel ordre des poètes et des témoignages pour faciliter l’étude de ces textes. Nous espérons que cette thèse contribuera à une meilleure compréhension de cette production méconnue et invitera à des nouvelles recherches. / After the death of Euripides and Sophocles, tragic poets continue to write tragedies. During the fourth century BC theatre expanded all over the Greek world. In this thesis, I propose a new edition of the tragic fragments of the fourth century BC, by poets who were active from the end of the Peloponnesian war to the death of Alexander the Great. The edition of these texts is preceded by a brief introduction on each poet and followed by a critical apparatus, their translation and commentaries. I also propose a new order of the poets and testimonies in order to facilitate the study of the texts. I hope this thesis will contribute to a better understanding of this relatively unknown production and inspire new researches.

La cellulose bactérienne (CB) est bien connue pour sa biocompatibilité, moulabilité, pureté et cristallinité ainsi que pour sa structure fibrilleuse nanométrique. Cependant, la production des matériaux par des microorganismes est innovante. La présente thèse initialise ce type de bioproduction dans nos laboratoires. Les bactéries productives de cellulose sont isolées à partir d'un vinaigre Libanais. Plusieurs études cinétiques sont établies. Les isolats sont étudiés dans différents milieux de cultures en variant la source de carbone et la température d'incubation, pour déterminer les conditions optimales recommandées pour la production de meilleurs rendements de CB. La bactérie productive de CB a été étudiée en détails au niveau de son cycle de vie et phases de croissance. La physiologie des cellules a été clarifiée et les mécanismes qui précédent et qui accompagnent la synthèse de CB ont été expliqués. Un modèle mathématique se basant sur l'équation logistique est employé pour standardiser les paramètres étudiés. Le rendement de CB a été accru en appliquant différents chocs aux cellules. Le choc thermique appliqué pendant les étapes précoces d'incubation ainsi que le choc acide ont montré des résultats innovants et accéléré le métabolisme de synthèse de CB. L'aspect environnemental du travail a été valorisé en préparant un milieu de culture extraits des fruits et légumes endommagés. En termes d'application, la CB a été utilisée pour produire des papiers et des papiers résistants à l'eau et comme additive dans un prototype d'industrie de papier. Ainsi des composites de cellulose/Liquides ioniques ont été produits afin de performer des matériaux à haute constante diélectriques / Bacterial cellulose (BC) is a wellknown polymer of this family. Its main attractive properties are the biocompatibility, moldability, purity, crystallinity and fibrillar structure at the nanoscaled level. The production of such materials by microorganisms is an innovative procedure. In order to trigger this production procedure in our laboratories, the present thesis was the preliminary step to go through this huge micro-world. In the first step, we isolated cellulose producers from Lebanese vinegar. Kinetic studies were established to clarify the profile of the producer and to optimize cellulose production. The isolates were studied under different incubation temperatures in different microbiological media and at different carbon sources levels to determine optimal conditions for BC production. In the second step, cellulose producer was studied concerning bacterial phases and life cycles. Cells physiologies were clarified and mechanisms that accompany cellulose formation on the top of cultures were discussed. A mathematical model was set basing on Logistic equation to standardize the parameters. Then, cellulose yield was enhanced by different cells choc methods. Thermal choc was applied on cultures during earlier stages of incubation. Moreover, acids were used as doping agents to the culture media. In parallel, to satisfy the eco-friendly aspect of the work, bacterial cellulose production was optimized using fruits and vegetables wastes juice. Papers and waterproof papers were produced using BC. BC was also used as an additive in industrial paper making and was found to enhance mechanical resistance of the papers. In addition, a high-K material was performed using bacterial cellulose and ionic liquids
