改进的S模式纠错算法

对检测到错误的S模式应答信号报文纠错,传统的方法是查表法,不仅效率很低,而 且要求很大的存储空间存放错误图样,不适合工程应用。通过对S模式应答信号的干扰情况 、编译码方式及循环码特性的深入研究,提出了余数计算的改进方法;再结合使用码元置信 度,实现了能快速、准确定位误码并纠正它们的算法。改进的纠错算法不仅效率高,而且占 用系统资源少,易于硬件实现,其有效性已得到工程应用的验证。     

Trade in Services: The Elasticity Approach for The Case of Turkey

This study includes the analysis of global trade in the services and service sector in Turkey, and estimates the elasticity of trade in services to real exchange rates and income. There is an increasing role of the service sector in the Turkish economy; however, a decreasing trend of trade in services is taking place. The commitments of the General Agreement on Trade in Services (GATS) were found to be ineffective, at least in the case of Turkey. The empirical findings suggest that the real exchange rate is not a significant determinant for the trade in services. We found an inelastic real exchange rate and income elasticities in trade demand functions. However, the value of income elasticity significantly exceeds the value of real exchange rate elasticity.     

Impacts of the End of the Coffee Export Quota System on International‐to‐Retail Price Transmission

We examine the impact of the end of the coffee export quota system (EQS) on international‐to‐retail price transmission in France, Germany and the United States. We take account of the existence of long‐run threshold effects and short‐run price transmission asymmetries (PTAs). We find evidence of threshold effects in both periods (EQS and post‐EQS) in all three countries and the presence of short‐run PTAs during the post‐EQS period in all countries, but not during the EQS period. Our results indicate that the threshold values are smaller in the post‐EQS period, suggesting that retail prices became more responsive to changes in international prices. However, the speed of adjustment towards the long‐run equilibrium decreases during the post‐EQS period in the three countries. In the short run, non‐linear impulse response analyses indicate that a shock in international prices was more persistent during the EQS period than in the post‐EQS period. Moreover, we find evidence of short‐run PTAs in the post‐EQS period, with differences across countries. We find support for the ‘rockets and feathers’ principle in the United States; in contrast, retail prices respond faster when international prices are falling in Germany and France. We explain these differences in terms of market structures.     

Threshold Cointegration in the Greek Milk Market

This article investigates the nonlinear adjustment between consumer and producer prices in the Greek milk sector using a threshold error correction autoregressive model. The results reject the null hypothesis of linear cointegration in favor of a 2-regime threshold cointegration model. A cointegrating relationship is expected only when equilibrium consumer price is decreased more than 24.12% or the equilibrium relative markup is squeezed more than 62.74%. In this case consumer prices have to increase faster than producer prices to restore the long-run equilibrium between consumer-producer milk prices.     

人力资源市场和谐发展的宏观视角研究——基于山东劳动力市场的实证分析

合理解决劳动力就业问题已成为经济能否持续有效发展、创建和谐社会的关键因素之一。文章以山东为例,利用协整检验对长期模型中可能影响劳动力就业的GDP增长、外商直接投资、三大产业结构特征以及教育和技术研发投入金额等因素进行实证分析;利用向量误差修正模型和广义脉冲响应函数研究各影响因素对人力资本市场需求的短期冲击;同时利用Granger因果检验对各主要影响因素和就业情况的内在因果关系进行检测;最后对我国劳动力就业形势进行预测并提出相关政策建议。     

基于ECM的我国税收弹性实证分析

运用时间数列和计量分析方法,利用1978--2006年我国税收收入和GDP数据,针对1978—1994年和1995--2006年两个阶段分别建立误差修正模型,对我国税收的长期弹性和短期弹性进行分析。研究结果发现：1978—1994年我国税收的长期弹性小于其短期弹性;自1995年以来,我国税收弹性发生了显著变化,税收的长期弹性大于其短期弹性。     

语言学层面的网络流行语解读

网络流行语是指伴随现实社会新闻事件的发生而在网络几近同步产生、迅速流行风靡于网络内外、短时间内生命力极其强大但并不长久的热门词语,归属网络语言。流行快,传播广、意义飘、使用活是其袁象特征。网络流行语是一种社会现象,由大众集体认同,约定俗成,形象化、格式化和简单化是其得以流行的关键。     

从“出格”与“变奏”看英诗意境之延展

节奏具有超词语表现力;英语诗歌的节奏及模式能表达出各种不同的情感与心境,继而渲染、浓郁着诗篇的意境。借助认知诗学的基本理论,采用华兹华斯的名诗进行分析与论证,获得了某种节奏与意境之间的文化、心理联系。但这种联系在两者给定状况下并没有对应准则,它随作者与诗篇的改变而改变;诗篇节奏模式中节奏单元的改变与诗篇意境的延展之间同样没有规律可循。     

银行结售汇与人民币汇率预期的实证分析——以广东省为例

近年来中国银行结售汇顺差额不断扩大是外汇储备规模快速积累的最直接原因,而人民币升值预期则被认为是银行结售汇顺差额扩大的重要影响因素。这个观点虽然被广泛认同,但相关的定量研究却相当欠缺。以境内外汇黑市汇率作为人民币汇率预期的量化指标,应用计量经济学方法对广东省银行结汇和售汇的月度时间序列数据进行定量分析,表明结售汇增长是外向型经济规模扩大的结果,同时人民币升值预期显著地提高银行结汇的增速并降低银行售汇的增速,导致结售汇顺差额的不断扩大。     

新时期高校学风建设的实践与创新

学风是一所学校或学者的治学精神、治学态度和治学方法的外在表现。随着高等教育教学改革深入和知识经济的到来,质量意识在不断升温,各高校对学风建设非常重视。走出认识误区和实践误区,有效加强学风建设,是当前高校最紧迫的任务。
