高速SDRAM控制器设计的FPGA实现

同步动态存储器(SDRAM)控制器通常用有限状态机实现,对于一般的设计方法,由于状态数量多,状态转换通常伴随大的组合逻辑而影响运行速度,因此,SDRAM控制器的速度限制了SDRAM存储器的访问速度。该文从结构优化入手来优化方法,利用状态机分解的思想将大型SDRAM控制状态机用若干小的子状态机实现,达到简化逻辑的目的,不仅提高了速度还节省了资源,对该类大型SDRAM控制器的实现有一定参考意义。     

The Experience of Gender Change in Public Sector Organizations

The state has a twofold relationship to gender change in society, through its overall steering capacity and through the gendered character of its constituent agencies. It is therefore important to understand the experience of gender change in state organizations. The findings from a study of gender relations in ten public‐sector worksites in New South Wales, Australia are presented. There is a widespread consciousness of gender change linked with new labour processes, restructuring and new patterns of management. These changes are uneven and limits to change are visible. Gender is recognized as an organizational problem in specific circumstances, most visibly where men’s resistance to change appears. A number of mechanisms limit the consciousness of gender as a problem. Several trends, including the current strength of neo‐liberalism, converge to make the gender‐neutral workplace the principal goal of gender reform in the public‐sector workplace. This, however, limits the state’s steering capacity in regard to societal gender relations.

The effects of social and political openness on the welfare state in 18 OECD countries

Studies examining the relationship between globalisation and the welfare state tend to focus on the effects of economic dimensions of globalisation, the extent to which a country is part of the world market. Globalisation also has social and political dimensions and the effects of these on welfare states – in terms of social security transfers and generosity – are studied in this article. Data from the KOF Index of Globalisation , the OECD Historical Statistics and the Comparative Welfare Entitlements Dataset are used to analyse the effects of social and political openness on the welfare states of 18 countries of the Organisation for Economic Cooperation and Development between 1970 and 2000. The analyses show that social security transfers and generosity have increased less in countries with the highest increase in social openness and that the welfare state is not affected by political openness.     

State‐led transnationalism and migration: reaching out to the Argentine community in Spain

Abstract This article focuses on when and how states develop transnational policies. It presents a case study of a relatively small emigrant community, whose departure was not simply caused by poverty or crisis, but most recently by an economic and political debacle that questioned people's values and expectations. I focus on the state side of the equation and identify a shift in Argentina's policy after 2003, though also show how such policies came out of a long history of state intervention in population and migration and are now related to human rights concerns and the unfinished process of democratic consolidation. I argue that the state initiates political transnationalism, not migrants, and highlight the importance of some relatively unexplored factors in the understanding of the motivation, intensity and impact of the state's involvement, such as the characteristics of the emigrant community, the existence of specific political projects, the role of some domestic actors and processes, and the nature of international agreements.     

我校大学生的营养状况调查与对策研究

对三峡大学的部分学生的营养状况、营养知识和饮食行为进行问卷调查,结果表明:大学生营养不良程度较轻,其饮食的月消费水平大都在200~400元之间,但营养知识的掌握情况一般,同时存在一些不良的饮食行为,因此,学校应强化营养知识教育,在加强后勤管理与改革的同时,把提高学生食堂供餐的营养质量作为一项重要的工作来抓。     

B股与H股及红筹股之间的溢出效应与信息流动

运用向量GARCH-M模型检验了B股与H股及红筹股之间的溢出效应与信息流动.实证结果表明:红筹股对沪深市B股、H股对沪市B股的收益和波动溢出效应均显著存在,而反向的溢出效应均不显著,表明信息是从红筹股向沪深市B股、从H股向沪市B股单向流动的;深市B股与H股之间相互的收益溢出效应均存在,而波动溢出效应均不存在,信息在H股和深市B股之间的流动情况不明显;在信息流动过程中,红筹股始终处于信息领先地位.     

对两权分离改革范式的十大实证性批判

两权分离改革范式的根本错误 ,不仅在于理论上缺乏行为分析性 ,更在于在实践中所引发的众多难题 :颠倒了自然人产权奠定法人产权的历史关系 ;没有解决国企所有者缺位的核心问题 ;延误了我国非国有企业的制度建设与全面成长的历史机遇 ;违背了世界经济发展的历史事实和基本趋势 ;没有彻底触动政治体制 ;没有解决不合理的社会关系 ;增大了我国制度变迁与经济发展的交易费用 ,没有解决国企企业家成长的制度问题 ;导致经济发展中短期化行为放大 ;社会资产缺乏理性投向。两权分离改革范式导致中国至今的经济改革走样 ,给经济发展带来现实与潜在的巨大危机与困难

住房价格上涨与其影响因素之间的关系研究——基于VEC模型的实证分析

通过建立向量误差修正模型,对中国近年来住房价格持续上涨的原因进行了分析。结果表明,土地价格的快速上涨、金融对房地产业的过度支持以及在住房价格继续上涨预期刺激下的投机因素是中国住房价格上涨过快的主要原因。近年来中国住房价格的持续快速上涨在很大程度上是一种泡沫现象。
