基于聚类和最优尺度分析的户外拓展运动的安全风险研究

Study on the Safety Risks of Outward Bound Sports Based on Aggregation and Optimal Scaling Analysis

户外拓展运动是一种需要进行风险管理的活动形式。文章基于户外拓展学员的认知,对拓展活动的安全风险引致因素和安全风险表现类型进行问卷调查,并对风险引致因素类型和风险表现类型进行聚类分析。研究引入最优尺度分析中的非线性典型相关分析方法,对个体因素与拓展安全风险间的相关关系进行统计识别。研究发现,拓展安全风险引致因素和拓展安全风险表现类型均具有聚类特征,并与拓展参与者的个性特征变量具有非线性相关关系。

Outward bound sport is a kind of activity that requires risk management.The paper,based on the perceptions of outward bound sport trainees,conducts questionnaire survey on the causing factors and types of safety risks and makes aggregate analysis for their types of expression.By introducing the method of nonlinear canonical correlation in the optimal scaling analysis,the study makes a statistical identity of relevant relationship between individual factor and safety risks.The study finds that both causing factors of safety risks and types of expression are of aggregate characteristics and are of nonlinear relationship with variables of individual characteristics of the participants.
