Cusp Catastrophe Model of Employee Turnover.
构建了一个尖点突变模型来解释护理人员的离职行为，发现离职者在离职前组织承诺更低，且工作紧张和承诺的感知会先越过阈值。
A cusp catastrophe model is developed to explain job turnover of nursing employees. The temporal dynamics of the catastrophe model suggest that leavers experience lower organization commitment than do stayers prior to termination. Leavers' perceptions of job tension and commitment appear to cross the threshold levels prior to the termination dates.
