基于单片机的数据复用器研究

本文探讨的是一个两路的数据复用器，该数据复用器采用异步串行通信方式，主要用89C51单片机来实现，我们从硬件和软件两方面完成了数据复用器的设计与开发及调试，通过实际的安装，基本达到了该复用器的设计性能指标，它具有结构简单、体积小、传输数据可靠等特点。     

Can Production Subsidies Explain China's Export Performance? Evidence from Firm‐level Data*

This paper analyses the relationship between production subsidies and firms’ export performance using a very comprehensive and recent firm‐level database and controlling for the endogeneity of subsidies. It documents robust evidence that production subsidies stimulate export activity at the intensive margin, although this effect is conditional on firm characteristics. In particular, the positive relationship between subsidies and the intensive margin of exports is strongest among profit‐making firms, firms in capital‐intensive industries, and those located in non‐coastal regions. Compared to firm characteristics, the extent of heterogeneity across ownership structure (SOEs, collectives, and privately owned firms) proves to be relatively less important.     

Safe Harbours in Merger Guidelines: What Should They Be?

Safe harbours in merger guidelines define post‐merger market concentration or concentration change thresholds below which proposed mergers are unlikely to be anti‐competitive; anti‐competitiveness is usually measured as a ‘substantial lessening of competition’. Yet competition agencies have different safe harbours. We used merger models to run many simulations involving a wide range of market structures and merger‐induced aggregations. The post‐merger unilateral price increases in these scenarios were used to gauge what the safe harbours should be to keep price increases below a specified threshold. The safe harbour thresholds commonly used were found typically to be too restrictive, in that they failed to screen out mergers that were almost certainly competitively benign.     

未婚青年生殖健康咨询服务利用与评价

利用2009年全国青年生殖健康可及性抽样调查数据,通过描述性统计对15-24岁青年生殖健康咨询服务利用状况与效果进行研究.2009年青年咨询需要率(人次比人数)为39.1%,同时超过80%的青年未报告有任何咨询需要;此外农村15-19岁男性咨询需要率与实现率(人次比人次)都高于同龄女性,但有咨询需要的比例低于女性,可见未婚青年尤其是农村15-19岁男性的生殖健康状况严峻.需要为未婚青年尤其是农村15-19岁男性青年提供一揽子咨询服务.不同咨询途径存在的问题不同,需要有针对性地提高青年生殖健康咨询服务的可及性.     

液晶电视动态LED背光源技术及其应用

目前LED的电光效率还不够高,亮度固定的LED背光源影响到显示图像的画质不能进一步提高,而且耗能发热而影响产品可靠性。本文研究的基于FPGA技术的分区动态控制LED背光源技术,其动态对比度特性明显的提高了液晶图像画质,大大的降低了液晶显示器(电视机)的实际使用功率,为提高画质和节能做出进一步的贡献。

CAS理论视角:财务核心能力系统演化过程探析

财务核心能力在企业发展过程中呈现动态性。本文运用CAS理论对财务核心能力系统的演化过程进行分析,确定了财务核心能力系统是一个复杂适应系统,根据CAS理论原理建立财务核心能力系统演化过程模型,并将该过程分为确定主体、主体个体演化以及系统整体演化三个阶段。     

建立我国科学、新型的预算管理制度

财政部部长项怀诚指出：预算改革是一场深刻的革命，改革的重点已转移到财政支出管理方面。论文对我国近期一系列预算探索加以概括性地总线。提出部门预算应成为预算编制的基本组织形式，零基预算编制的基本方法；国库集中收付制是预算执行的基本形式。同时提出复式预算应是政府对经济实施宏观调控的重要政策工具。     

国企人才流失风险的识别与防控

企业普遍偏低的人力资源素质是无法通过人力资源的数量代替的。造成国企人才流失风险的内部因素归为观念落后、用人机制不合理、缺乏合理的绩效考核机制、分配制度不合理、待遇偏低。提出国企人才流失风险防控措施:严把招聘关;提供具有竞争力的薪酬待遇;设计有吸引力的福利;引入职业生涯规划;建设一支高素质的领导队伍;加强企业文化建设。最后提出企业若想提高效率,留住人更为重要,否则优秀人才的流失,将直接影响企业的兴旺与发达。
