Research On The Influencing Mechanism Of The Individual Crisis Behavior Decision-making Based On Information Dissemination

Individual suicide,murder and other crisis behavior incidents occur frequently,it seriously threatening the social harmony of our country,and causing a huge negative impact on the family.Individual crisis behavior has become a social problem of widespread concern in our country.Individual crisis behavior is mostly caused by emotional,interpersonal,life pressure and other issues.Because information affects individual decision-making,this thesis,explores the set of factors affecting individual crisis behavior decision-making,and the linkage effect between these factors based on the process of information dissemination and grounded theory,and constructed a decision tree model of individual crisis behavior based on ID3 decision tree algorithm.Finally,we put forward some suggestions to prevent and control the individual crisis behavior according to the research results.The main contents of this thesis include:(1)Constructing the conceptual model of "the influencing factors and mechanism of individual crisis behavior decision-making from the perspective of information dissemination" based on the grounded theory and method,and following the logic of individual information acquisition → individual information processing → individual information experience.And analyzing the typical structural relationship among the main categories,and explaining the mechanism of individual crisis behavior decisionmaking.(2)Collecting 226 effective cases of individual crisis situation from network and interviews to obtain data taken by standardization.Taking the five main categories as conditional attributes and constructing the decision tree model 1 based on ID3 decision tree algorithm.For further study,we introduced the grey relational entropy and constructed the decision tree model 2 based on the first seven with larger grey relational entropy from nine conditional attributes by dividing the initial categories.And we compared and analyzed the two decision tree models;(3)Giving five countermeasures and suggestions from environmental factors and self-factors according to the conceptual model and decision tree results of individual crisis behavior decision-making,which may provide reference for the prevention and control of individual crisis behavior.Through the above research,we find that there are 32 initial categories affecting individual crisis behavior decision-making,which including 11 information attributes,16 individual attributes and 5 experience attributes.There are five main categories affecting individual crisis behavior decision-making.Among them,interpersonal relationship information and interpersonal network information under three-degree influence space determined the scope of information acquisition and characteristics of information distribution for individual crisis behavior decision-making.Cultural environment influences individual decision-making by influencing individual characteristics.And according to the information experience,the twoway decision-making model of individual crisis behavior is obtained: attitude → reasoning path and behavior imitation → connection path.In addition,the feedback process is composed of individual characteristics and information dissemination experience through the rumination.By comparing and analyzing the consistency of the two decision tree models,it is found that environmental information can be used as an important basis for individual crisis behavior.Therefore,based on the perspective of environment and individual itself,this thesis puts forward prevention and control countermeasures,that is,to improve cultural environment as a long-term plan to prevent and control individual crisis behavior,to create a harmonious threedegree influence space for others,to interfere with the psychological survival strategy in individual crisis situation,to change the pessimistic attitude in individual crisis situation,and to prevent individual crisis behavior from imitating.
