  • 简介:劳动供给曲线是一条在某个工资率之上向后弯曲的曲线,在关键点(C点)以上,提高工资会减少提供的劳动数量。当收入效应大于替代效应,即收入较高时,员工感到有能力享用更多的闲暇,即使每一增加的闲暇小时具有较多的用牺牲掉的工资来计算的代价。由此得出企业人力资源激励不能只用金钱,同时指出了SA8000标准对当代企业的要求,并提出了企业内部无薪激励的建议以及企业在无薪激励中应该注意的其他一些问题。

  • 简介:研究了退火气氛对ZnO:N(氮掺杂的氧化锌)薄膜的光电性质影响。结果发现,n型电导原位生长的ZnO:N薄膜样品,经过600℃O2气氛下退火后,样品A表现为P型电导特征;而经过600。CNz气氛下退火后,样品B仍然表现为n型电导特征。低温光致发光光谱(PL)测试表明,样品A和样品B的发光光谱最大的差别为样品A的低温发光光谱中具有与受主相关的发光峰,峰位位于3.348eV;样品B的低温发光光谱中具有与施主相关的发光峰,峰位位于3.358eV。
