This research asks the question: “What are the relational dynamics in Masters (MA) supervision?” It does so by focusing upon the supervisory relationship itself. It does this through dialoguing with the voices of both MA supervisors and supervisees in the Humanities using a Cultural Historical Activity Theory (CHAT) framework. In so doing, this research argues for a re-evaluation of how MA supervision is conceptualised and proposes a new theoretical framework for conceptualising MA supervision as a relational phenomenon. The research design was derived from an Activity Theory-influenced methodology. Data collection procedures included the administration of Activity Theory Logs, individual semi-structured interviews with both supervisors and supervisees and the completion of reflective journals. Grounded Theory was used to analyse the data. The sample for the study consists of three supervisor-supervisee dyads from three disciplines in the Humanities. Data was collected over the course of one academic year, 2010-2011. This research found that both individual and shared relational dynamics play an important role in MA supervision. Individual dynamics, such as supervisors’ iterative negotiation of ambiguity/clarity and supervisees’ boundary work, revealed that both parties attempt to negotiate a separation between their professional-academic identities and personal identities. However, an inherent paradox emerged when the shared relational dynamics of MA supervision were investigated. It was found that the shared space created by the supervisory relationship did not only exist in a physical setting, but was also psychoactive in nature and held strong emotional resonances for both parties involved. This served to undermine the separation between professional-academic and personal identities. As a result, this research argues that the interaction between the individual and shared relational dynamics in MA supervision enables, for both supervisors and supervisees, a disciplined improvisation of academic identity.

The aim of this thesis was to investigate the high prevalence of Clostridium difficile in patients with cystic fibrosis (CF), and to control its dissemination. To determine the carriage rate of C. difficile in CF patients, 60 patients were tested for C. difficile and its toxin. In total, 50% of patients were found to be asymptomatic carriers of C. difficile despite toxin being detected in 31.66% of patients. Ribotyping of the C. difficile isolates revealed 16 distinct ribotypes, including the hyper virulent RT078. All isolates were sensitive to both Vancomycin and Metronidazole. The effect of CF and its treatment on the gut microbiota of CF patients was assessed by 16s sequencing of the gut microbiota of 68 CF patients. When compared to a healthy control group, CF patient gut microbiota was found to be less diverse and had an increased Firmicutes to Bacteriodetes ratio. Interestingly, CF patients who were carriers of C. difficile had a less diverse gut microbiota than C. difficile negative CF patients. Multilocus sequence typing was found to be comparable to PCR-ribotyping for typing C. difficile isolates from high risk patient groups. The sequence type ST 26 is potentially associated with CF patients as all seven isolates were found in this group and this sequence type has been previously reported in CF patients in a geographically distinct study. The bacteriophage ФCD6356 was assessed as a targeted antimicrobial against C. difficile in an ex-vivo model of the human distal colon. Despite reducing viable C. difficile by 1.75 logs over 24 hours, this bacteriophage was not suitable due to its lysogenic nature. Following treatment, all surviving C. difficile were immune to reinfection due to prophage integration. However, the ФCD6356 encoded endolysin was capable of reducing viable C. difficile by 2.9 over 2 hours in vitro after being cloned and expressed in Escherichia coli.
