Introduction The process of decision making has been widely studied within different academic paradigms. Many theories and models have been developed from this research activity. However, there is a lack of in-depth research on individuals’ experience of decision making. The present research explores this topic with Clinical Psychologists. This group of professionals are trained to be expert in a specific discipline, which emphasises the need for making informed judgements and for justifying decisions. Objectives To provide an in-depth account of how Clinical Psychologists experience decision making in the context of clinical practice. To relate the analysis to theories and models of decision making and to research on factors thought to influence judgement and decision making. Method Semi-structured interviews were conducted with seven Clinical Psychologists. These were transcribed and analysed using Interpretative Phenomenological Analysis (IPA) methodology. Outcomes Elements of the decision making environment such as managing one’s conflicting beliefs and difficult emotions, responding to uncertainty and changeable scenarios and normative versus unique elements of one’s practice were elucidated in the analyses. The contribution of this work to research in decision making and the development of clinical practice are discussed.

Sustainable development and sustainable living, a key pursuit of our times, must be premised on human well-being in order to be truly sustainable. Although many have speculated on the possible interaction between sustainable lifestyle practices and the well-being, or satisfaction, of practitioners, there has been limited empirical study of this connection. The purpose of this study was to explore how people experience satisfaction and frustration in conjunction with the practice of a sustainable lifestyle. Semi-structured interviews were completed with six sustainable lifestyle practitioners associated with Transition Victoria, a community resilience initiative in Victoria, British Columbia, Canada. Interview transcripts were synthesized into explanatory narratives highlighting experienced outcomes of a sustainable lifestyle practice. A further thematic analysis was completed to identify themes to which participants attributed meaning and potential satisfaction. The results of this analysis were interpreted to draw conclusions about the sorts of satisfying and frustrating experiences that were related to sustainable lifestyle practices for these participants. Results of the study revealed twenty-six salient themes of important, potentially satisfying phenomena anticipated and experienced by participants. These included needs for food, shelter, transportation, money, health, well-being, relationships, connection, communication, support, recognition, legitimacy, effectiveness, autonomy, action, enjoyment, knowledge, interest, nature, meaning, and identity, and also needs to pursue certain values. Various actions, relationships, and contexts constituting sustainable lifestyles had implications for both satisfying and frustrating essential needs for security, belonging, esteem, competence, knowledge, creativity, leisure, and autonomy. In addition, the pursuit of a sustainable lifestyle was related to the need for and satisfaction of meaning. The results of this study suggest that, for this small group of participants, sustainable lifestyles hold multiple opportunities for satisfaction and frustration of various needs. Groups wanting to support sustainable lifestyle practitioners might consider ways to maximize opportunities for satisfaction and meaning, and minimize sources of frustration. It is recommended to conduct further research with a larger sample of participants, to extend these findings to more general conclusions about human experiences with sustainable living. / Graduate

It is well known that for small Reynolds numbers, flow around a cylinder is laminar and stable. For larger Reynolds numbers, although the flow regime remains laminar, the formation of complex periodic structures appear downstream. The cyclic nature of this periodic flow is well characterized by the vortex shedding frequency and Strouhal number. However, complexities of these periodic structures downstream continue to be a topic of research. Periodic laminar 2D incompressible viscous flow around a cylinder is simulated using OpenFoam, an open source computational fluid dynamics program. To better understand these complex structures downstream, a customized computer graphical tool, VerFlow-V.01, was created to analyze and study OpenFoam simulation results. This study includes an investigation of calculating the details of drag and lift coefficients for the cylinder using mathematical models that integrate properties in subdomains, an approach not previously explored to the knowledge of the author. Numerical integration is accomplished using a finite difference approach for solving surface and contour integrals in subdomains of interest. Special attention is given to pressure and to the second invariant of the velocity gradient, as they have a clear mathematical relationship, which is consistent with results previously published. A customized visual data analysis tool, called VerFlow-V.01, allowed investigators to compare simulation data variables in a variety of useful ways, revealing details not previously understood. Main subroutines and a user's manual are included as appendices to encourage reproducibility and future development of the numerical, analytical and graphical models developed here. Together these models resulted in a new understanding of periodic laminar flow around a cylinder. A unique approach was developed to qualitatively understand the origins of drag and lift coefficients associated with properties mapped as images in subdomains of interest downstream. These results explain the development of convergent, eddy, and stream zones embedded in flow fields downstream. / Master of Science
