人力资本自上而下的代际传递是现有文献研究的重点,但鲜有文献关注人力资本自下而上的代际传递以及性别差异。本文基于中国健康与养老追踪调查数据,利用1986年《义务教育法》实施这一外生冲击,通过工具变量法研究子女教育对父母健康的影响及作用渠道。研究发现,子女教育提升显著改善了老年父母的生存预期、躯体健康、认知功能和抑郁情绪。进一步地,通过对情感和经济支持两方面的异质性机制分析,我们发现这种反哺模式呈现出“儿子出钱、女儿出力”的性别差异。

A Distributed Cell Outage Compensation Mechanism Based on RS Power Adjustment in LTE Networks

引用

China Communications 2014年第A01期11卷 40-47页

作者： LI wenjing YU peng YIN Mengjun MENG Luoming StateKeyLaboratoryofNetworkingandSwitchingTechnology BeijingUniversityofPostsandTelecommunicationsBeijing100876China

To solve the coverage and quality problems caused by cell outage in LTE networks, this paper proposes a distributed self-organizing networks management architecture and a distributed cell outage compensation management mechanism. After detecting and analyzing the outage, a cell outage compensation algorithm based on reference signal power adjustment is proposed. The simulation results show that the proposed mechanism can mitigate the performance degradation significantly. Compared with other algorithms, the proposed scheme is more effective in compensating the coverage gap induced by cell outage

植物芬多精可增强人体免疫力,抑制癌细胞生长,具有较为特殊的医学功能,同时具有一定调节血压、缓解精神障碍、降低血糖、缓解疼痛、抗痉挛的保健作用。随着近年来我国森林康养产业的迅速发展,森林芬多精的研究与开发利用日益受到学者们的重视。探究森林康养植物所释放的挥发性有机物中芬多精的组成成分、相对含量及日动态变化特征,可为森林康养活动的开展和康养时间与地点的优化选择提供参考依据。以国家级森林康养基地中两个特色的森林康养植物鸡爪槭(Acer palmatum)和肉桂茶树(Camellia sinensis)为研究对象,使用动态顶空吸附采样法(dynamic headspace collection)定时定量进行样品采集,采用Entech7200预浓缩和Agilent 7890B/5977GC-MS联用仪进行分析,鉴定鸡爪槭和茶树(肉桂)这两个特色植物VOCs中芬多精的组成成分、相对含量及日动态变化特征。结果表明:两种森林康养植物的芬多精组成成分主要以烷烃类、醇类、芳香烃类、酮类、醛类、萜烯类六种挥发性有机物为主,其中占比相对较高的为烷烃类(鸡爪槭20.6%,茶树25.92%)和芳香烃类(鸡爪槭15.26%,茶树11.93%)。2种植物芬多精的重要成分萜烯类物质的相对含量鸡爪槭较高于茶树(高出0.18%),且2种植物萜烯类相对含量均表现出相同的日变化特征,即上午8:00和下午16:00的萜烯类相对含量较高,而中午12:00的相对含量最低。因此,在森林康养基地建设和森林康养植物选择时可优先选择具体高观赏价值和较高芬多精含量的鸡爪槭,且森林康养活动开展的时间于上午8:00和下午16:00的时间段开展较为适宜。
