中学生人格现状分析与思考

通过对400名中学生人格现状的调查和分析,发现中学生:(1)在学习和生活态度方面:有奋斗目标,但有一部分同学在奋斗过程中遇到困难易动摇,甚至采取逃避态度。明确追求个人利益。在学习过程中,有部分同学缺乏持之以恒的意志力,学习上的竞争意识较强,但对竞争手段、方法认识有误。(2)在评价自己方面:参与管理社会的热情不高。对自己如何适应社会竞争缺乏正确认识。缺乏自我监控能力。(3)适应社会能力方面:处理事情有一定的果断性,但也存在着优柔寡断的毛病。对国际国内政治、经济等重大新闻不够关心,有一部分同学对集体的利益荣辱漠然视之。(4)人际交往范围较窄。本文从6个方面提出了如何培养中学生健全人格的思路和设想。

形式与思想的完美统一——《致他羞涩的情人》之语篇分析

选择就是意义,形式是意义的体现。在文学作品篇章表层形式后往往隐藏着作者的深刻用意。人们可以从四个角度,即人称代词、时态、篇章结构以及修辞手段等,对17世纪英国玄学派诗人安德鲁.马伏尔著名的情诗《致他羞涩的情人》进行鉴赏。这首诗以歌颂"及时行乐"为主题,整首诗逻辑严密,用词准确,比喻奇特。如果从语篇分析角度出发,即通过对篇章的一些表层形式的剖析,则能更深层次地挖掘出诗人所要明确表达的精神主题。

Cooperative Sensor Anomaly Detection Using Global Information

Sensor networks are deployed in many application areas nowadays ranging from environment monitoring, industrial monitoring, and agriculture monitoring to military battlefield sensing. The accuracy of sensor readings is without a doubt one of the most important measures to evaluate the quality of a sensor and its network. Therefore, this work is motivated to propose approaches that can detect and repair erroneous (i.e., dirty) data caused by inevitable system problems involving various hardware and software components of sensor networks. As information about a single event of interest in a sensor network is usually reflected in multiple measurement points, the inconsistency among multiple sensor measurements serves as an indicator for data quality problem. The focus of this paper is thus to study methods that can effectively detect and identify erroneous data among inconsistent observations based on the inherent structure of various sensor measurement series from a group of sensors. Particularly, we present three models to characterize the inherent data structures among sensor measurement traces and then apply these models individually to guide the error detection of a sensor network. First, we propose a multivariate Gaussian model which explores the correlated data changes of a group of sensors. Second, we present a Principal Component Analysis (PCA) model which captures the sparse geometric relationship among sensors in a network. The PCA model is motivated by the fact that not all sensor networks have clustered sensor deployment and clear data correlation structure. Further, if the sensor data show non-linear characteristic, a traditional PCA model can not capture the data attributes properly. Therefore, we propose a third model which utilizes kernel functions to map the original data into a high dimensional feature space and then apply PCA model on the mapped linearized data. All these three models serve the purpose of capturing the underlying phenomenon of a sensor network from its global view, and then guide the error detection to discover any anomaly observations. We conducted simulations for each of the proposed models, and evaluated the performance by deriving the Receiver Operating Characteristic (ROC) curves.
