This study is concerned with what is happening within a mentorship interaction between engineers aimed at knowledge transfer. The practice of knowledge transfer is contextualised within the knowledge economy that ideologically positions Western economies as knowledge holders and advanced, while positioning developing countries as knowledge deficient and backwards. The prevailing literature regards knowledge transfer as difficult to achieve and is primarily focused on factors that hinder its success, looking to causal relational factors between and within the participants, in particular the qualities of knowledge receivers. Constructing the relationship and the individuals engaged in knowledge transfer as problematic brings about certain types of relations between individuals and between groups. These bring into play the positioning of role players within knowledge transfer that is not neutral, creating asymmetrical power relations and impacting identity construction. Studies in knowledge transfer have examined the factors that inhibit successful knowledge transfer extensively and do not consider its discursive context or considerations of power relations. Based on the assumption that discourse produces social practices and individual identities within social, historical and cultural contexts, this study adopted a social constructionist perspective and suggests that the ways in which identities are constructed in a mentorship interaction affect how participants experience and make sense of their worlds, which has implications for the practice of knowledge transfer. Viewing power as embedded in relations, a Foucauldian Discourse Analysis was conducted of discursive constructions generated from 17 interviews of participants engaged in a multinational knowledge transfer project between South African and Saudi Arabian engineers. The analysis showed that the construction of self and other does have an impact on knowledge transfer between Saudi Arabian and South African engineers. The multiple identity constructions of the participants within the knowledge transfer relationship were resourced from dominant discourses that reveal different meanings attributed to the participants’ mentorship experience and showed the systematic setting up of self and other within unequal power relations that favour the self. The study suggests that deeper consideration should be given to the effects of othering and power within social interactions between individuals located in divergent contexts such as those that characterise knowledge transfer. / Psychology / Ph.
