Congratulations to Shalinka Jayatilleke, Nick Dejkovski, Tariq Halimi, Teddy Kwakye, Stephen Sim, Joni Vendi, Minh Phong Nguyen and Thi Hoa Nhai Pham on passing their PhD thesis examination and being awarded their PhD’s. Read about their PhD topics below, and check out some of the great graduation pictures.

Dr Shalinka Jayatilleke

Dr Jayatilleke investigated the issue of managing software requirements changes in the Information Technology industry which often result in problems like cost overruns and project delays.  She has developed a method each for; (i) change specification and classification; (ii) change analysis; and (iii) rework assessment, in order to help alleviate the problems.

 

Dr Teddy Ossei Kwakye

Dr Kwakye examined the effect of business strategy on the cost of external financing. The findings show that innovative-oriented firms have higher cost of equity than their efficiency-oriented counterparts due to their greater non-diversifiable business risk and lower quality of financial reports. The research advances business strategy as a direct antecedent of firms cost of equity capital.

 

Dr Tariq Halimi

Dr Halimi examined the influence of political relations between countries on the consumer purchase decision. It was found that positive relations between countries can provide a competitive advantage for their international companies when marketing their products. This thesis contributes to theory development in consumer purchase decision-making and develops a conceptual model that has implications for marketers.

 

Dr Stephen Sim

Dr Sim explored the ethical HRM of workers with a range of mental and intellectual disabilities at two Australian social enterprises. To better support workers with disabilities with inclusive practises, organisational management should not only focus on policies and practises, but also provide innovative and positive workplace experiences.
