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.     

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。     

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.     

Regional job-turnover and industrial policy. a note on a potential time pattern of regional industrial policies and their job effects - the case of the german city-state of bremen

Many regions have experienced long-run economic fluctuations generated by the life cycles of their dominant industrial clusters. During the downswings in the 1970s and 1980s, proactive structural policies were typically launched in German regions to combat job losses in their core clusters and to create new jobs in new industries. With respect to the German State of Bremen, this paper provides empirical evidence of: (1) a long-run regional downswing; (2) the potential job effects of proactive regional industrial policy programmes in terms of increasing regional employment, by safeguarding jobs in the regional core industries and creating new jobs in new growth industries; and (3) a time pattern in the job effects, which are related to the different generations of programmes.     

Planning food services for a campus setting

Providing appropriate food services in a campus setting is increasingly important due to more demanding customers and because clients have less time to go off-campus when they need to eat. Using a university campus as an example, this research looks at customer satisfaction with existing food services and explores various methods for determining where to locate new facilities. This campus currently has great needs for additional food services, and it is shown clearly where additional food services are required. Also, the methods used are compared in terms of their effectiveness in finding the solution.

灰关联分析在房地产开发方案评选中的应用

项目可行性研究在房地产项目开发决策中得到了广泛的应用，但目前可行性研究主要是进行项目的经济论证，忽视了项目的技术论证，即开发方案的评价。本文首先强调了开发方案评价的重要性，分析了开发方案评价时应考虑的因素，以及这些因素对提高土地利用率、降低开发投资的影响，并拟定了相应的评价指标。通过对评价问题的分析，提出运用灰色数学理论来进行开发方案的评价，并对评价指标权重的确定进行了改进，文章的最后结合具体实例予以验证。
