查询词典 variation

In contrast, the postulate that the impact of sunk cost on willingness to continue a project is moderated by risk perception is supported, with results indicating that the lower degree of risk perception will cause greater effect of sunk cost on willingness to continue a project, which will lead to the sunk cost effects more easily. Therefore, the variation in willingness to continue a project as a result of variation in level of sunk cost can be significantly better explained when risk perception is introduced as a moderating factor.

This paper reports the varied flowers in syconia of Ficus awkeotsang Makino. We used anatomic observation and statistical analysis to analyze the variation in female and male flowers, mutation rate of different strains and number of varied flowers per syconia in syconia from 24 female and 16 male strains. We also discuss the relation between flower variation and pollinating wasp activity or yield of F. awkeotsang by observing flower development. The results revealed 2 types of flowers in morphology: an umbrella inflorescence shape and solitary.
