《左传》预言发微

预言贯穿《左传》全书，这是其叙事的一大特色。按其预测的依据将预言分为两类，并对其中通过观察人事所作的预言进行重点分析。从中可以看出作者的历史观、伦理道德观和劝善惩恶的史学见解，。这些预言在全书的结构、叙事中也起到了很重要的作用，研究《左传》的文学成就应予重视。

几个确定型量子信道的构造（英文）

通过概率信道的隐形传态通常依赖于高维的幺正操作,而在物理实验中实现高维的幺正操作是非常困难的.为了了解怎样通过几个常见概率信道去构造确定性的量子信道.在方案中,发送者或接收者需要引入一个或多个辅助粒子到概率信道中使之融入并纠缠于原有量子,然后对辅助粒子进行投影测量或半正定算子值测量,就能以一定概率建立起发送者及其客户之间的确定性量子信道.在量子通信网络中,通常有多个不同的代理商作为发送者与接收者之间的中继节点,因此,给出了构造发送者和中继代理援助的接收者之间的确定性信道的几个方案。     

A National Investigation of Teachers’ Environmental Literacy as a Reference for Promoting Environmental Education in Taiwan

Taiwan's government enacted the Environmental Education Act in June 2011. In the beginning of the implementation of the Act, a national assessment of schoolteachers’ environmental literacy was performed in order to establish the baseline for evaluating the effectiveness of environmental education policy. This large-scale assessment involved a large sample size of in-service teachers across schools at all levels and regions in Taiwan using the stratified random sampling method. Data showed that the teachers have satisfactory levels of environmental knowledge and attitudes, but presented low degrees of environmental action. Differing from previous research results, elementary teachers performed better than high school teachers on this assessment, which may be attributed to their teacher training experiences. Results from this study may provide implications for teacher professional development programs and school environmental education policy.

An Ontology-Based Binary-Categorization Approach for Recognizing Multiple-Record Web Documents Using a Probabilistic Retrieval Model

The Web contains a tremendous amount of information. It is challenging to determine which Web documents are relevant to a user query, and even more challenging to rank them according to their degrees of relevance. In this paper, we propose a probabilistic retrieval model using logistic regression for recognizing multiple-record Web documents against an application ontology, a simple conceptual modeling approach. We notice that many Web documents contain a sequence of chunks of textual information, each of which constitutes a record. This type of documents is referred to as multiple-record documents. In our categorization approach, a document is represented by a set of term frequencies of index terms, a density heuristic value, and a grouping heuristic value. We first apply the logistic regression analysis on relevant probabilities using the (i) index terms, (ii) density value, and (iii) grouping value of each training document. Hereafter, the relevant probability of each test document is interpolated from the fitting curves. Contrary to other probabilistic retrieval models, our model makes only a weak independent assumption and is capable of handling any important dependent relationships among index terms. In addition, we use logistic regression, instead of linear regression analysis, because the relevance probabilities of training documents are discrete. Using a test set of car-ads and another one for obituary Web documents, our probabilistic model achieves the averaged recall ratio of 100%, precision ratio of 83.3%, and accuracy ratio of 92.5%.
