The first and foremost person I am grateful to is my supervisor Dr Hayley Myers who guided me throughout the research and served as a beacon of hope and motivation during the research process. The extraordinary motivation, support and guidance provided by my supervisor has helped me throughout the research process in different stages such as developing an appropriate research topic, preparing an effective research proposal and finally conducting the research and completing the associated research report. I would also like to thank all my colleagues and participants who gave me their previous time to conduct the research in an effective manner. I am also thankful to all my family members who have supported and motivated me throughout my life and the significant emotional support provided by my family has enabled me to conduct this research in an effective and appropriate manner. I also need to declare my appreciation to my old friends for their understanding, support and the time we have shared.
