Acknowledgment

In all humility I bow before God, the compassionate and most merciful who gave me the brain to think and capability to hear so to know what I do not.

The words can’t express my gratitude to my family for their support, encouragement and sacrifices to push me up to this level in my academic journey. I also could not undertake this journey without particular motivation from my lovely and learned Sister MARANATHA and my learned brother MARCEL who generously provided their knowledge support and being referred to as my knowledge base.

This Endeavor would not have been possible without the generous knowledge contribution and support from HELEN PUTLAND who supported me since the first day at the University and continued to provide her support throughout this journey.

I am grateful to all my university lecturers and support team for their great teaching experience and support throughout my learning journey.

Additionally, I’m thankful to Dr. MOHSIN IFTIKHAR and KENNETH EUSTACE form Charles Sturt University for their encouragement and cooperation during my research work.

I am also grateful to all my best and close friends for their feedback, motivations and moral support. Thanks, should also go to my Pastor MWENDAMBALI for all the prayers you have been doing for this success.

Finally, I would express my gratitude to my lovely parents who always believe in me and support me.
