Moral shielding: A grounded theory of integrity maintenance in multidisciplinary teams

Using a classic grounded theory methodology (CGT), this study explores the phenomenon of moral shielding within mental health multidisciplinary teams (MDTS). The study was located within three catchment areas engaged in acute mental health service practice. The main concern identified was the maintenance of a sense of personal integrity during situational binds. Through theoretical sampling thirty two practitioners, including; doctors, nurses, social workers, occupational therapists, counsellors and psychologists, where interviewed face to face. In addition, emergent concepts were identified through observation of MDTs in clinical and research practice. Following a classic grounded theory methodology, data collection and analysis occurred simultaneously. A constant comparative approach was adopted and resulted in the immergence of three sub- core categories; moral abdication, moral hinting and pseudo-compliance. Moral abdication seeks to re-position within an event in order to avoid or deflect the initial obligation to act, it is a strategy used to remove or reduce moral ownership. Moral gauging represents the monitoring of an event with the goal of judging the congruence of personal principles and commitments with that of other practitioners. This strategy is enacted in a bid to seek allies for the support of a given moral position. Pseudo-compliance represents behaviour that hides desired principles and commitments in order to shield them from challenge. This strategy portrays agreement with the dominant position within the MDT, whilst holding a contrary position. It seeks to preserve a reservoir of emotional energy required to maintain a sense of personal integrity. Practitioners who were successful in enacting moral shielding were found to not experience significant emotional distress associated with the phenomenon of moral distress; suggesting that these practitioners had found mechanisms to manage situational binds that threatened their sense of personal integrity.

Synthesis of 4-substituted-3(2H)-furanones with novel luminescence properties

The objective of this project was to prepare a range of 4-substituted 3-(2H)-furanones, and to investigate the relationship between their molecular structures and photoluminescence properties. The effects of substituents and conjugated linker unit were also investigated. After generation of the key 3(2H)-furanone heterocycle, extension of the conjugated framework at the C-4 position was achieved through Pd(0)-catalysed coupling reactions. Chapter one of the thesis comprises a review of the relavent literature and is split into three sections. These include information about the prevalence of 3-(2H)-furanones as natural products and synthetic routes to 3-(2H)-furanones in general. The synthetic routes are divided according to the synthetic precursor employed. The final section of chapter one outlines the fundamental principles and application of photoluminescence to organic compounds in general. Chapter two contains the results of the research achieved in the course of this work and a discussion of the findings. Two routes were successfully employed to generate 4-unsubstituted 3-(2H)-furanone moieties: (i) base induced cyclisation of hydroxyenones and (ii) isoxazole chemistry. A number of methods which proved ineffective in the production of furanones with the desired substitution pattern are also detailed. The majority of this study was focused on the introduction of substituents at the C-4 position of the 3-(2H)-furanone ring. This was achieved through the use of Sonogashira and Suzuki cross coupling protocols for Pd(0) catalysed C-C bond formation. The further functionalisation of some compounds was performed using transfer hydrogenation and “click chemistry” methodologies. Finally, the photophysical properties of 3-(2H)-furanones prepared in this project are discussed and the effect of substitution patterns in a complementary “push push” and “push pull” manner have also been investigated. All the experimental data and details of the synthetic methods employed, for the compounds prepared during the course of this research is contained in chapter three together with the spectroscopic and analytical properties of the compounds prepared.
