加入WTO对江苏农业的影响

加入世贸组织对江苏农业究竟有什么样的影响？为了回答这一问题，我们首先应当了解加入世贸组织要求中国农业做出什么样的让步。目前世贸组织关于农产品贸易的规则是其前身关贸总协定在最后一轮多边贸易谈判即乌挂圭回合上做出的，这些规则将在２００４年前后被新一轮多边贸易谈判达成的协议取代。由于这一原因，加上通常应有的过渡期，主要贸易伙伴在中国加入世贸组织的谈判中提出的条件多半以２００４年为界。因此，我们可以依据这些贸易伙伴提出的条件评价中国加入世贸组织以后农业在短期内可能受到的冲击到底有多大，对江苏农业的影响有…     

Bad Days Don't End When the School Bell Rings: The Lingering Effects of Negative School Events on Children's Mood, Self-esteem, and Perceptions of Parent–Child Interaction

Each day for five days, 79 fifth‐grade children reported on events that occurred at school and they and their parents described their interactions with each other each evening. Consistent with previous research, it was found that on days when children reported more academic or peer problems during the day at school, they later described more aversive interactions with their parents. As hypothesized, increases in anxiety and drops in children's state self‐esteem partially mediated this link. However, parents did not report any differences in their interactions with the target child on days when the child experienced problems at school. This study suggests that negative events experienced by children while at school lead to short‐term changes in mood and self‐esteem, which influence their perceptions of subsequent interactions at home with parents.     

人民币汇率失衡与调整问题研究

 摘　　要:目前，学术界在人民币汇率问题的研究上存在着分歧。尤其是对均衡汇率的测算，在方法上存在不足。多数模型的设计实质上是把名义汇率或实际有效汇率的平滑值当作了均衡汇率，而非真正的经济学意义上的均衡汇率。本文设计了一种“多目标两阶段估值”的方法来测算均衡汇率：在第一阶段，依据实现均衡汇率的各个目标，分别估算不同目标条件下的均衡汇率；第二阶段，以第一阶段估算的均衡汇率和实现均衡汇率的各目标建立计量模型，得到均衡汇率精算值。在深入分析汇率失衡给宏观经挤带来的后果的基础上，依据均衡汇率的计算结果，本文认为，提升汇率符合中国的长期利益和根本利益，而且在觋阶段政府还不应该放弃对汇率调整的干预

汉字发展过程中的调整与完善

汉字在其发展演变过程中,一直在不断地进行调整与完善,汉字的分化是其中一项重要的调整手段。一方面有同形字的分化,另一方面也有因词义引申和汉字假借等引起的分化。这种分化是遵循一定的规律的,发现并研究这种规律,对于我们认识汉字历史、指导汉字改革均具有重要意义。

A Note on Exponentially Smoothed Seasonal Differences

Filtering economic time series can be justified if variations within a certain frequency interval are relevant for the problem at hand. It is shown here that exponential smoothing of seasonal differences provides a simple means of damping short oscillations, including seasonal ones.     

P-value adjustment for multiple binary endpoints

The p-value-based adjustment of individual endpoints and the global test for an overall inference are the two general approaches for the analysis of multiple endpoints. Statistical procedures developed for testing multivariate outcomes often assume that the multivariate endpoints are either independent or normally distributed. This paper presents a general approach for the analysis of multivariate binary data under the framework of generalized linear models. The generalized estimating equations (GEE) approach is applied to estimate the correlation matrix of the test statistics using the identity and exchangeable working correlation matrices with the model-based as well as robust estimators. The objectives of the approaches are the adjustment of p-values of individual endpoints to identify the affected endpoints as well as the global test of an overall effect. A Monte Carlo simulation was conducted to evaluate the overall family wise error (FWE) rates of the single-step down p-value adjustment approach from two adjustment methods to three global test statistics. The p-value adjustment approach seems to control the FWE better than the global approach Applications of the proposed methods are illustrated by analyzing a carcinogenicity experiment designed to study the dose response trend for 10 tumor sites, and a developmental toxicity experiment with three malformation types: external, visceral, and skeletal.
