新型波导-微带对脊鳍线过渡设计

介绍了一种新型的宽带波导-微带对脊鳍线过渡设计。它利用对脊鳍线自身结构的调整,就可以对频带内谐振频率产生抑制作用,不需外加任何谐振抑制结构或金属孤岛,减少了设计和制造的复杂性。这种紧凑的过渡模型不仅结构简单、尺寸短小,而且可以在宽频带范围内实现较低的插入损耗和回波损耗,方便工程上的应用。对实验样品的测试表明,在Ka全频段内其插入损耗小于0.8 dB。     

The governance of privatized firms: authority,reposnisbility and disclosure1

In any market economy, a fundamental question is how to make management accountable to shareholders and also to the requirements of law. This paper raises selective, critical issues of corporate governance that are particularly relevant to problems of the accountability of boards of directors to their shareholders in transition economies. These issues include the separation of ownership and control and the duties of directors; the need for disclosure given that separation; and the corporate charter as a vehicle for the direct participation of shareholders in governance. The paper suggests that one of the best models of corporate governance that transition economies can use is that employed by the leveraged-buyout (LBO) and venture capital funds operating in the West. It argues that weaknesses in corporate governance may undermine the entire privatization process. Economics and law are too often seen as separate disciplines. In reality, they come together in transition economies perhaps with greater impact than elsewhere.     

固定利率住房抵押贷款对我国商业银行利率风险的影响

我国利率市场化改革正在稳步地向前推进,利率风险在商业银行经营和管理中的重要性正在、并且将会不断凸现。目前,我国商业银行的利率敏感性资产小于利率敏感性负债,重新定价缺口为负缺口,固定利率住房抵押贷款的推出使重新定价负缺口有进一步扩大的趋势。本文从边际的角度分析了固定利率住房抵押贷款对我国商业银行利率风险的影响。由于目标间的冲突,文章的结尾指出我国商业银行有实现战略转型,由目前短期内净利息收入最大化实现向股东权益价值最大化转变,同时兼顾监管时期内资本金条件约束的现实必要性与迫切性。     

Enhanced co-citation analysis using frameworks

The valuation of intangible assets, such as patents, has recently been considered an important technique for R&D strategies. This paper proposes a citation analysis as a method of valuation on patent clusters having patent networks. A citation analysis is a method that examines the value of a patent on the basis of the number of citations of references. In particular, a co-citation analysis is used for coupling patents as the patent cluster and valuating the patent cluster. While the co-citation analysis is of great interest as a method of valuation, this analysis has not been fully examined and does not define any framework for a technology transition and patent strategy. Therefore, in this paper, the conventional co-citation analysis for evaluating the patent clusters is enhanced and frameworks for the technology transition and patent strategy are proposed by analysing citation routes in a co-citation analysis.     

Confirmatory and Structural Categorical Latent Variables Models

The paper proposes a general framework for modeling multiple categorical latent variables (MCLV). The MCLV models extend latent class analysis or latent transition analysis to allow flexible measurement and structural components between endogenous categorical latent variables and exogenous covariates. Therefore, modeling frameworks in conventional structural equation models, for example, CFA and MIMIC models are feasible in the MCLV circumstances. Parameter estimations for the MCLV models are performed by using generalized expectation–maximization (E–M) algorithm. In addition, the adjusted Bayesian information criterion provides help for model selections. A substantive study of reading development is analyzed to illustrate the feasibility of MCLV models.     

林业资源型城市经济转型扶持政策研究

资源型城市经济转型是一个巨大的系统工程,不仅要依靠资源型城市自身力量来完成,还需要中央和地方政府的有关政策扶持,林业资源型城市也不例外。论述林业资源型城市进行政策扶持的必要性。阐述一些西方国家针对不同类型的资源型城市的特点制定的一系列较为完善的扶持政策,如法国和德国主要依靠政府的干预,日本则通过产业政策对煤炭行业进行结构调整等政策促进城市经济顺利转型。在借鉴国外资源型城市转型扶持政策的基础上,提出促进黑龙江省林业资源型城市经济转型的扶持政策,即资源开发的补偿政策和衰退产业的扶持政策,及具体实施办法,以期促进林业资源型城市经济顺利转型。     

Employment fluctuations and dynamics of the aggregate average wage in Poland, 1996–20031

The aggregate average wage is often used as an indicator of economic performance and welfare, and as such often serves as a benchmark for changes in the generosity of public transfers and for wage negotiations. Yet if economies experience a high degree of (non‐random) fluctuation in employment, the composition of the employed population will have a considerable effect on the computed average. In this paper we demonstrate the extent of this problem using data for Poland for the period 1996–2003. During these years the employment rate in Poland fell from 51.2 percent to 44.2 percent and most of this fall occurred between the end of 1998 and the end of 2002. We show that about a quarter of the growth in the average wage during this period could be attributed purely to changes in employment.     

A Gini decomposition analysis of inequality in the Czech and Slovak Republics during the transition1

Disposable income inequality, as measured by the Gini coefficient and using the Family Budget Survey data, increased very little, and by a similar amount, from 1989 to 1993 in the Czech Republic and Slovakia. This surprising result is examined with an analysis of changes in the channels of redistribution and Gini decomposition. We find that the sizeable increase in overall inequality due to changes in the wage earnings component is mitigated by changes in the tax and transfer components in both republics. As for the relative effects of government policies, changes in the transfer component contributed more than changes in the tax component to lowering the growth of inequality in the Czech Republic, while the reverse was true for Slovakia.

The Operating Performance of Newly Privatised Firms in Central European Transition Economies

This study examines the operating performance of privatised firms in three Central European Transition Economies between 1990 and 1998. Overall, we find no evidence of a significant improvement in operating performance for the first six years after privatisation. Contrary to the increasing empirical evidence for non‐transition economies, our privatised firms experience no improvement in profitability, capital investments, efficiency, and output, a significant drop in employment, as well as a significant increase in leverage. The most important determinants of the performance changes following privatisation were country effects, timing of the privatisation sales, industry classification, and state ownership after privatisation. Our findings are consistent with the empirical evidence that the transition process proved to be more difficult than expected and that, although necessary, privatisations do not necessarily produce equal efficiency gains in transition economies ( Megginson, 2005 ; Havrylyshyn and McGettigan, 1999 ).
