Moodley, cannot be over emphasised. In the form of guided thinking and motivation, you kept me going. I deeply acknowledge your hard work around the clock to ensure the timeous completion of this research. Your commendable supervisory roles cannot go unmentioned.To my late grandmother for the words you said to strengthen me at the time I needed them the most (to put the pieces back together and soldier on). Those words still keep me going.With much appreciation I acknowledge the support and love of Miss Lebala Miriam Kolobe for being with me every step of the way. May you be rewarded many fold. This study would not have been a success without the willing contributions of the participants. I salute you all for devoting some time out of your tight schedules towards the success of this study.To my colleagues in the Masters programme, I thank you all for the useful discussions I acknowledge the co-operation and support of my principal, Mr A.S. Dlamini and his two deputies Mr Sakhile Mngomezulu and Mr Frank Khumalo, as well as the entire management of Kwasanti secondary school, for granting me the permission to collect the data for this study from the nearby schools during my free periods. Thank you also for your support in all these years. And last but not least, to the principals of the participating schools, I say thank you; your tolerance is deeply acknowledged and appreciated.
