    反馈是控制论中的重要概念,指控制系统把信息输出后,信息作用的结果又将返回控制系统,并对控制系统的再输出发生影响,而信息在这种循环往返的过程中,不断改变内容,实现控制。控制论的创始人维纳说过“这一控制原则不仅适用于巴拿马运河船咱闸,而且也适用于国家、军队和个人……这一社会反馈问题具有极大的社会学和人类学的意义”[1]反馈作为重要的传播资源在传播过程中发挥独特的调节功能,但在传播的实践中,反馈却是一个薄弱的环节,传播者并不十分重视开发反馈资源,反馈所发挥的作用也十分有限。本文即是关于政府传播反馈问题的一个研究,为了更具有针对性和操作性,本论文从政府传播反馈渠道之一的公众组织——NGO入手,试图对政...Feedback is an important concept in Cybernetics, which means after the output of information, the result would return the control system, and influence the reexport of the information .

    大学生创业教育伴随着知识经济的来临而日益成为世界各国高等教育的改革方向,也将成为我国全面建设小康社会进程中促进经济发展、缓解就业压力和推动教育改革的重要思路。厦门大学大学生创业教育起步较早,在创业教育的探索与实践方面居于我国大多数高校的前列,但与试点院校相比又有所差距,可以说,厦门大学创业教育的现状具有普遍性和代表性。本论文以厦门大学为个案进行研究,以期窥一斑而知全豹,并在此基础上尝试为我国高校实施大学生创业教育理出一条理想的思路。本研究的调查分析主要围绕四个方面进行:一是大学生创业教育实践基本经验总结;二是大学生创业教育实施现状;三是大学生创业教育制约因素;四是大学生创业教育的指导思想。通过...Since the advent of IT era, undergraduate enterprise education has been growing into a world-wide trend in higher education. It will become an important concept in the course of Chinese comprehensive construction of a well-to-do society, which helps to accelerate economic development, to abate unemployment pressure, and to promote educational innovation.

    性别失衡、婚姻挤压与个体劳动参与

    \"女性赤字\"的性别失衡现象对男女双方在婚姻市场的竞争机制和劳动力市场的供给决策产生了深刻影响。本文利用2005年1%人口抽样调查和2010年第三期中国妇女社会地位调查数据,综合考察性别比结构对我国婚姻市场和个体劳动参与的影响。研究发现,性别比提高会显著降低男性的婚姻议价能力,从而导致婚姻挤压现象,其中文化水平低下的农村男青年遭受的挤压最为严重。正是由于婚姻挤压的中介机制,性别比上升会使得男性在劳动力市场付出更多,因而男性劳动参与率显著上升,而女性的劳动参与率显著降低。此外发现,性别失衡会使女性获得更大的家庭决策权和自主权,并增加对女性家庭劳动的需求从而对市场劳动形成替代(即\"非劳动收入效应\"和\"替代效应\")。本文不仅为评估性别失衡经济社会影响提供确凿的微观证据,也在一定程度上提供新的政策洞见。国家社会科学基金青年项目“女性就业视阈下我国性别失衡的劳动力市场效应研究”(批准号:16CRK017)阶段性研究成

    Late Quaternary Sediment Stratigraphy and Marine Cycles in the Pingtan Island, Fujian Province

    选择位于福建平潭岛北部芦洋埔海积平原的PT01钻孔,岩芯长度28.3 m,采用加速器碳同位素(AMS 14C)和光释光(OSL)测年建立地层年代框架,认为晚更新世富含有孔虫等海相生物化石的地层应归属于MIS 5高海面期,即MIS 5e的潮下带滨海相沉积。结合岩性特征、古生物化石、沉积物色度、粒度分析及其参数等指标,进行了沉积单元的划分,重建了MIS 6末期以来的沉积相变化过程,揭示出MIS 5期间的多次海平面波动变化,即MIS 5高海面期沉积环境仍存在滨海、潮坪、潟湖、风成砂等沉积相之间的转换,并可能存在短暂的陆相或风化过程。而该区整个末次冰期的沉积缺失或较薄,上部全新世沉积也不发育,厚度仅为3.79 m,以沼泽相―风成砂相为主。A 28.3 m long core, PT01, from the Pingtan Island, Southeast China, is selected to be studied. Radiocarbon dating(AMS 14C) and optical stimulated luminescene(OSL) are used for establishing chronology. Combining age-dating results with marine microfossil and color index, we classify the Late Quaternary sediment stratigraphy in the coastal region of Fujian Province. It is suggested that the late Pleistocene marine deposit, dated back to 124 ka, and abundant marine microfossil(e.g. foraminifer and ostracods), would belong to the Marine Isotope Stages 5(MIS 5). Moreover, the late Quaternary sediment could be divided into three units based on the analysis of lithology, microfossil, grain size and color index. Our results reveal that the sediment environment during the MIS 5 was significantly controlled by global sea level change which varied among coast, tidal flat, lagoon, and eolian sand, and probably there existed weathering process. A hiatus during the last glacial(MIS 2-4) was attributed to low relative sea level. And the Holocene deposit, as thick as 3.79 m, developed poorly and was mainly comprised of swamp facies and eolian dune.国家自然科学基金(41230101、41072128
