Knowledge brokering is showing significant potential as a means of increasing the use of research in policy making. Using research to inform policy making is critical to achieving policies that are 'evidence-based' and result in policy outcomes that have greater potential to address the 'wicked' social problems that governments are facing. Research provides governments with the knowledge to make sense of policy problems, develop policy solutions and evaluate their effectiveness. Despite extensive attention given to better understanding the barriers and facilitators to research utilisation, the use of research to inform policy decisions remains elusive.Advocates of a close relationship between the 'two communities' of policy makers and researchers believe this relationship is the key to effective policy formulation based on sound research.Knowledge brokering is emerging as a promising means of linking, and facilitating exchange, to form effective relationships between the 'two communities' of academics and policy makers, building on interactive models of the policy making process. More specifically, knowledge brokering is the human component of knowledge mobilisation, using relationships to move knowledge between policy makers and academics. In doing so, knowledge brokering works to overcome the barriers that hinder research utilisation.While there has been an increased interest in the past decade in understanding and defining the activities of knowledge brokering, the role and effectiveness of knowledge brokering in moving research into the policy making process is unclear. Furthermore, much of the focus in the literature to date is on knowledge brokering activities carried out by individuals, but the dependence of these knowledge brokering activities on the organisational context in which these individuals operate has largely been ignored in the literature. Hence, the study of knowledge brokering organisations may be very important in understanding how knowledge can be effectively transferred between knowledge producers and users.To address the research problem, two separate yet related research components were undertaken, and these research components are described across three core sections of this thesis. Part A of the thesis provides the essential conceptualisation and operationalisation of the research questions based on current debates within the extant literature on knowledge mobilisation and knowledge brokering. Part B of the thesis analyses surveys and in-depth interviews with policy officials and social scientists to make conclusions on the perceived need for, and existence of, knowledge brokering roles and activities in the movement of knowledge into the policy making process in ii Australia. A typology of organisations that operate in a knowledge brokering capacity in Australia has been developed. Part C adopts a multiple-case study design to investigate one type of entity operating in a knowledge brokering role within key public policy areas in Australia -researchfocused intermediary organi...
