The communication framework and knowledge infrastructure diagram

This diagram is a knowledge infrastructure proposal that addresses the needed communication between the experts involved in problems such as light pollution. The framework consists of a four-cluster-ring-diagram that includes the communication network needed between the lighting industry and research to assess lowering light pollution. Via this framework, we established that (1st ring) a lighting foundation and (4th ring) an ecological ceiling are two boundaries needed to exchange knowledge on (2nd ring) the parameters to consider for research and (3rd ring) research parameters to consider for the lighting practice. It is a collaborative framework based on communication and knowledge transfer needed to address matters such as light pollution.
