The Emergence of Molecular Biology in the Diagnosis of Cervical Cancer: A Network Perspective

Abstract
Cytology-base technologies have been extensively used for decades to diagnose cervical cancer in women despite the large number of false negative cases those may report. The rise of molecular biology, since mid-1980s, has spurred the emergence of novel diagnostic technologies, which have significantly changed both the research landscape and clinical practices around cervical cancer. Within this context, the present paper examines how different institutional groups of actors (research and higher education, governmental, hospital and care, industrial, and non-governmental organisations) have contributed to the emergence of molecular biology from an inter-organisational network lens (co-authorship data of publications). To do so, we analyse the patterns of network interactions among different institutional groups involved in the emerge process. We specifically examine the formation of ties (dyads) within and between groups as well as the extent to which organisational actors operate in di↵erent brokerage positions (triads) over the emergence process. The analysis is based on a sample of scientific articles published over more than 30 years in the diagnosis domain of cervical cancer research. Findings provide evidence that the process of tie formation as well as the brokerage activity follow different patterns according to the considered institutional group. The process of tie formation and brokerage activity also evolve over emergence.
