Dear Editor,Gynoecism has been extensively exploited in cucumber breeding. The utilization of a gynoecious line permits earlier pro- duction of hybrids, higher yield, and more concentrated fruit set. In addition, the utilization of a gynoecious line eliminates the need for hand emasculation and reduces the labor cost of crossing （Robinson, 2000）. Therefore, the development of gynoeoious inbred lines is instrumental for cucumber breeding. Gynoecious inbreds can be produced by selection from crosses of monoecious inbreds, or can arise spontaneously from natural variation. However, both methods have disadvantages. For instance, the time-consuming and laborious process of crossing can also lead to the introduction of undesirable traits,

本文使用2010年第三期中国妇女社会地位调查数据,研究了工作—家庭冲突对工作满意度的影响及其性别差异,发现来自工作和家庭两方面的角色压力是引发工作—家庭冲突的主要原因,而且无论是因工作影响家庭,还是因为家庭耽误工作,员工都会对工作表达不满。与男性员工相比,工作压力和家庭压力会使女性员工陷入更为严重的工作—家庭冲突,而且女性员工也更可能因为工作影响家庭而降低对工作的满意度。这些发现不仅为工作—家庭冲突及其相关后果的理论研究提供了丰富的经验证据,还为各级管理人员激励员工士气和提高组织绩效提供了很多实践上的启示。
