    新产品开发绩效是企业追求的重要战略目标,即开发出对本企业及其主要竞争对手来说之前没有的产品,贯穿产品研发、改进、市场化和产业化的全过程,其所创造的绩效就认为是企业的新产品开发绩效。新产品开发绩效可能产生提高企业创新绩效、为企业带来业绩增长、提高企业的市场地位等正向结果。因此,领导者必须掌握新产品开发绩效的影响机制,并且在管理过程中,更加重视对中高层管理人员的有效管理。 影响员工行为的重要情境因素包含了领导风格的种类,也就是说,下属员工将根据感知到领导者风格调整自身行为。特别是中高层管理人员,他们的行为往往能影响企业绩效。包容型领导普遍存在,但其对新产品开发绩效的影响机制的探讨还相对欠缺。因此...New product development(NPD) performance is an important strategic target of the corporate, develop products that are not previously for the corporate and its major competitors, throughout the product development, improvement, marketing and industrialization of the whole process, the performance is considered as the NPD performance.

    目的为了观察束缚固定和异氟烷(流量:0.8 L,浓度:1.5%)麻醉状态中大鼠的心率变异性的变化;并通过比较9天每天30 min束缚干预和异氟烷麻醉对大鼠的体重、痛阈以及与HPA轴相关激素的影响,来评估长期使用异氟烷麻醉和束缚固定对大鼠应激程度的影响,选择更适宜的大鼠固定方法,为基础医学的实验方法提供重要的参考。方法 SD大鼠随机分为3组:空白组,束缚组,异氟烷麻醉组。急性实验通过记录大鼠心电图15 min,观察束缚固定和异氟烷麻醉情况下大鼠心率,心率变异性的变化。慢性实验中比较连续干预9天(30 min/d)前后3组大鼠体重、痛阈变化以及与应激状态相关激素含量的变化。结果 1)急性试验:与空白组大鼠相比,束缚干预和异氟烷麻醉均造成大鼠心率显著增加,具有统计学意义(P 0.05)。结论以上结果提示:低浓度的异氟烷造成麻醉中大鼠心率增加,心率变异性下降,产生以交感兴奋为主的自主神经功能状态改变。多次束缚固定易造成大鼠HPA轴激活,产生慢性应激的效应。在长期需要固定动物的实验中,与束缚固定相比异氟烷麻醉是更好的固定方法。国家自然科学基金(81674083
