Published papers draw their conclusions from evidence contained within those papers and from previously published evidence as acknowledged by their citations to earlier literature. But how exactly do authors use earlier evidence? And what impact does this have on the evidence selected by others?
In this seminar, Rhodri expands on his work using claim-specific citation network analysis; moving beyond the detection of dissemination biases (citation bias and distortion) to identifying plausible mechanisms that underpin their propagation. Using a series of findings from his research on the dynamics of evidence selection in the evaluation of the diet – heart hypothesis, Rhodri focuses primarily on the structure of communication in the scientific literature as a likely candidate to explain the propagation of particular research findings. Using these as exemplars, he presents findings that suggest the presence of information cascades in the scientific literature, and how three measures, betweeness centrality, modularity, and transitive reduction, can help reveal structural causes that impinge on evidence selection.
This seminar will take place on 4th December, between 13.00 and 14.15, in the Practice Suite (1.12) of the Chrystal Macmillan Building.
