| Experts’ participation in controversial news events has become the norm in modern society.The solution of the problem and the settlement of the dispute need experts’ professional knowledge and rational thinking logic.However,the dispute is not only about the problem itself,the expert participation has become the focus of controversy and the object of questioning by the public,which is the manifestation of the expert trust crisis.This study takes the transgenic controversy,a typical scientific controversial news event,as a case.From a more micro perspective,experts themselves take the news event and the news text expert discourse of the news event as the research text.It finds that there are three main problems when experts participate in controversial news events :(1)experts word problems,namely the use of jargon and arrogance leads to can’t effective communication and dialogue with the public(2)cross-border speech problem,namely ignore discipline boundary problem lead to irresponsible(3)the interests of the experts and related issues,namely,in the face of temptation ignoring ethics moral interests,laws and regulations,the emergence of these problems lead to the emergence of expert credibility crisis;This study based on the theory of social role found at the same time,experts are often involved in controversial news event is not just in the "experts" role,will also such as "knowledge disseminator" "opinion leaders" "lay" into the role of "demonstrator",so the cause of the above problem is closely related to experts and role playing,the experts in this role transformation and play to their role in the process of contradiction or mutual coordination and eventually produce conflict,the specific reasons are as follows:(1)fuzzy and expert on popular disseminator role cognition field transformation brought about by the habitus inappropriate word problems led to the experts;(2)the internal change and modern science field specialization own disadvantages appeared in the society lead to the problem of crossing the line to speak;(3)the intervention of political power and capital as well as the limitations of China’s scientific research evaluation system led to the interests of the embedding problem.The discovery of the problem and the traceability of the problem provide a good foundation for the solution of the problem,and also point out the right direction for the conception and proposal of relevant suggestions:(1)the experts themselves should take the initiative to do self adjustment,discipline and at the same time to make changes,such as change of arrogance and discourse strategies to promote dialogue and exchanges with the public;strengthen the punishment mechanism to strictly restrain and restrict;moments grasp disciplinary boundaries of degrees in order to promote mutual exchanges and cooperation in the body of science;(2)the relevant institutions and the establishment of the national government should perfect the mechanism to promote the self-adaptation of experts,such as establishing incentive mechanism to encourage initiative of experts for the social public,the joint media institutions to improve the communication mechanism to promote expert face-to-face dialogue and exchanges with the public,improve the education and training mechanism to promote experts to deal with the media and the public’s ability and quality.Found and source based on the above problems,the complexity of the experts in controversial news events have been interpretation,which can not only help experts introspection the cause of the crisis of confidence,but also can help experts acknowledge its involved in controversial news events should has the ability and quality,at the same time also expect the public to understand the reasons of the problems of the many,promote the parties to understand each other,from another level reshaping expert trust;In addition,the proposal of relevant countermeasures and suggestions can add bricks and tiles to the effectiveness of science communication and public communication power,and can also help establish a good integrated model of knowledge communication. |
