Bayesian MCMC Mapping of Quantitative Trait Loci in a Half-sib Design: a Graphical Model Perspective

Graphical models provide a powerful and flexible approach to the analysis of complex problems in genetics. While task-specific software may be extremely efficient for any particular analysis, it is often difficult to adapt to new computational challenges. By viewing these genetic applications in a more general framework, many problems can be handled by essentially the same software. This is advantageous in an area where fast methodological development is essential. Once a method has been fully developed and tested, problem-specific software may then be required. The aim of this paper is to illustrate the potential use of a graphical model approach to genetic analyses by taking a very simple and well-understood problem by way of example.     

What＇s So Special about China＇s Exports？ A Comment

Dani Rodrik argues that China's exports are unusually sophisticated for a country at its income level. He also claims that China's export sophistication reflects the government's successful industrial policy and has been instrumental in the recent acceleration of its economic growth. Although Rodrik's interpretation of China's economic growth is broadly correct, the accuracy of his empirical analysis is questionable. This note identifies several problems regarding the “export sophistication” index used in his empirical work and casts doubt on his analysis.

基于方法分析的企业精细管理思想

本文认为,精细管理是企业管理走向科学化的必然要求,是科学管理发展到一定阶段的产物,是对管理实践的科学性概括和总结,是对企业管理创新的一个系统化梳理。精细管理具有系统化特征、理论与技术高度综合性特征、动态管理特征、实践性和全员参与特征;精细管理的闭路循环系统具有对应性,能够找到企业的每一个部门或个人的位置和相应的职责;精细管理在闭路循环系统中可以明确知道可能的效果倾向。文章提出,企业在实施精细管理的过程中,应适应变化的市场环境,把握精细管理的真正内涵;树立正确的企业精细管理理念,持之以恒;重构企业科学管理体系,走全员参与的精细管理之路。     

开放式基金投资风格浅析

近年来，开放式基金在我国发展极为迅速，在数量不断增加的同时，呈现出的风格日趋多样化。面对种类繁多的开放式基金，投资者很难分清哪种投资风格更适合自己的风险偏好，因而投资风格逐渐成为基金最重要的识别系统之一。本文首先介绍了开放式基金的定义，其次，根据财务指标对开放式基金的投资风格进行分类并描述不同类型基金的特点。最后分析了基金最终风格出现趋同的原因。     

基于协整分析的东北区域产业结构优化与金融支持关系研究

基于1978—2003年的统计数据,采用协整关系检验法和格兰杰(Granger)因果检验法对东北地区金融发展与产业结构优化之间的关系进行了实证检验。分析结果表明东北区域产业结构优化与金融发展之间存在长期动态均衡关系及单向因果关系,即金融发展对东北区域产业结构优化具有支持作用,从而为政府经济决策提供了政策依据。     

国库集中支付操作风险产生机理的博弈分析

国库集中支付操作风险是指国库资金支付过程中出现违规操作行为的可能性。国库集中支付制度框架下财政资金支付活动是财政部门、预算单位、代理银行和人民银行共同参与的博弈过程。本文运用博弈理论首先分析国库集中支付操作风险产生的内在机理，然后剖析国库集中支付操作风险产生的外在博弈条件，最后从优化博弈条件出发，提出建立健全监督激励机制以防范国库集中支付操作风险的建议。     

Domestic Support and Border Measures for Processed Horticultural Products

In horticultural markets, trade barriers often apply to the processed products whereas domestic support applies to farm-produced raw commodities. Here we assess the effects of such trade barriers and domestic support by simulating the effects of policy reform on global processing tomato markets, which are faced with modest processed product tariffs and high domestic support in the European Union (EU). Both protection and EU subsidy drive down world welfare, but we find that reducing import tariffs for tomato products would yield greater effects on markets and larger welfare impacts outside Europe than would reductions in EU domestic support.

Hypothesis tests using data envelopment analysis

A substantial body of recent work has opened the way to exploring the statistical properties of DEA estimators of production frontiers and related efficiency measures. The purpose of this paper is to survey several possibilities that have been pursued, and to present them in a unified framework. These include the development of statistics to test hypotheses about the characteristics of the production frontier, such as returns to scale, input substitutability, and model specification, and also about variation in efficiencies relative to the production frontier.
