Integration of prior research is critical in understanding the existing state of knowledge in the field. The Laboratory for Integration focuses upon two approaches. First, integrations are undertaken by way of support score and meta-analysis techniques when research questions arise that have an evidence base. Datasets of coded prior studies (coding to include policy issues, research design and size effects) will be developed. Second, to understand the nature of the field of study bibliometric studies will be conducted drawing on citation analysis to understand conceptual development in the field.
