非人灵长类的杀婴行为及其适应意义
杀婴 非人灵长类 雄性繁殖策略 杀婴行为的防范对策
font style='font-size:12px;'>
2016/7/20
杀婴现象普遍存在于非人灵长类种类中,本文通过综述目前已知的21 种非人灵长类的69 例杀婴行为记录,探讨了非人灵长类杀婴行为的适应性意义。大多数雄性杀婴行为符合雄性繁殖策略假说,既满足以下3 个条件:(1)杀婴雄性与受害婴仔没有父子关系;(2)失去婴猴的母亲会提前进入发情状态;(3)受害雌性随后可能与杀婴雄性交配。不过有些个别的杀婴现象与雄性繁殖利益无关,文中进一步介绍了误伤假说、减少未来竞争者假...
实践智慧是由亚里士多德明确倡导的,它具有慎思、明辨和中道的理论品格;但是实践智慧作为人类的主体性活动与人的发展关系,在亚氏之后渐渐成为绝响,中国哲学在这一问题上走在了前列。在实践智慧下,人格之美表现为内在的精神形态和外在的行为过程。实践智慧下内在的精神形态既是对于"中道"或"度"的把握,还表现为"仁、智、勇"的统一;外在的行为过程具体的指向知和行、言和行的统一,知行统一和言行统一就是理想人格的具体...

2012/11/7
为了解广东地区汉族人群的舌运动能力,选取了广东省化州市472例汉族进行了卷舌、叠舌、翻舌、尖舌和三叶舌5种舌运动类型的调查.结果显示:5种舌运动类型的出现率分别为52.54%,4.24%,18.86%,69.49%和6.36%,低于其他大多数族群,与南方族群更接近;除尖舌外男女之间无显著差异;卷舌-翻舌、卷舌-三叶舌之间的相关程度较高.表明广东化州地区汉族的舌运动能力总体上处于较低水平.
