基于最大熵谱估计的机载雷达杂波抑制技术

在讨论机载雷达地面杂波的基础上，利用最大熵估计法对机载雷达杂波进行抑制，并引入了ｃｈｏｌｃｓｋｙ分解快速算法求解最大熵谱的ＡＲ模型参数。计算机模拟表明，基于最大熵谱估计的机载雷达杂波抑制技术有很高的谱分辨率，不仅能跟踪主杂波的频率位置而且能跟踪其谱宽度，因而具有较为满意的杂波对消化与改善因子。     

Gini’s nuclear family

The purpose of this paper is to justify the use of the Gini coefficient and two close relatives for summarizing the basic information of inequality in distributions of income. To this end we employ a specific transformation of the Lorenz curve, the scaled conditional mean curve, rather than the Lorenz curve as the basic formal representation of inequality in distributions of income. The scaled conditional mean curve is shown to possess several attractive properties as an alternative interpretation of the information content of the Lorenz curve and furthermore proves to yield essential information on polarization in the population. The paper also provides asymptotic distribution results for the empirical scaled conditional mean curve and the related family of empirical measures of inequality.      

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.     

International Tax Competition: A Case for International Cooperation in Globalization

The liberalization of international financial flows and foreign direct investment has induced countries to use diverse measures to attract inflow of foreign capital and foreign direct investment, which is expected to have a positive effect on the growth of GDP and thus a positive effect on social welfare. Tax exemption, reduction of tax rate, tax holiday, or diverse subsidies are some of the most important measures used. In this paper we study international tax cooperation, i.e., countries change and especially reduce tax rate for corporate income or for asset revenues to attract inflow of foreign direct investment. Both theoretical and empirical studies have shown the sensibility of foreign direct investment decision with respect to tax rate differences between home countries and host countries. In general, more inflow of foreign direct investment can be expected if the tax rate of the home country is lower than that of foreign countries. This is the main reason for international tax cooperation. In this paper we propose a simple model to prove the sub-optimal Nash non cooperative solution in a two-country tax-competition game. The model shows that international tax cooperation can improve welfare of the participating countries. How to reach a cooperative solution for an international tax competition game (ITCG) is therefore an important issue for further discussions and studies. International institutions can play a crucial role to reach international tax cooperation or international tax harmonization.     

试论我国刑事附带民事诉讼执行

刑事附带民事案件执行比普通民事执行更难,有其自身特殊的原因。解决刑事附带民事执行难问题已不是执行机构单方面的努力所能解决的,而需要公安机关、人民检察院、监狱和刑事审判庭等各个部门的通力合作。解决刑事附带民事执行难的最终机制在于建立国家补偿制度。

一种自适应斜坡补偿电路

基于CMOS工艺设计了一种能够自动调节补偿斜率的斜坡补偿电路。该电路可以跟随输入和输出信号的变化,相应地给出适当的斜坡补偿量,不仅使得峰值电流模式BOOST变换器可以稳定工作,而且可以避免补偿不当的现象,保证变换器有足够快的瞬态响应。仿真结果表明该电路产生的斜坡补偿信号的精度可以达到83%以上。     

浅议精神损害赔偿举证责任制度的完善

作者分析了精神损害赔偿举证责任问题的现状,认为精神损害赔偿案件的受害者在事实上存在着举证困难的问题,如果局限于传统的民事诉讼举证责任原则,作为受害方可能无法进行有效的举证。因此,应当对精神损害赔偿举证责任问题作出特别规定,以切实维护受害者的合法权益。为了提高我国精神损害赔偿制度中的司法裁判的统一性,有效的保障当事人的合法权益,在精神损害赔偿案件中,应该从三个方面完善我国精神损害赔偿的举证责任制度:首先,慎重对待精神损害赔偿案件中的事实推定;其次,细化精神损害赔偿案件中的举证责任;第三,确立精神损害标准化的制度。     

薪酬策略与公司竞争战略的匹配机制研究

文章通过对185家企业的实地调研,比较了薪酬策略和公司竞争战略的两种匹配模式:中介匹配和调节匹配.否定了中介匹配模式,支持了调节匹配模式,从而解决了薪酬管理研究中长期存在的争议:两者到底是如何匹配的.公司竞争战略并不能自发地促生出相应的薪酬策略,而是需要相关部门较为独立地开发出相应的薪酬策略与之配套.最后,根据研究发现并提出了一些增进薪酬策略与公司竞争战略匹配度的建议.
