重视师生沟通优化班级管理

进行师生沟通，优化班级管理有四个要点，一是接近学生，熟悉学生；二是捕捉学生的闪光点，赞扬学生；三是形成健康的集体舆论；四是关心学生生活，参与学生的课外活动。     

"红"与"Red"的语义扩展对比研究

本文通过对汉语“红”和对应的英语“red”的语义扩展模式进行对比发现，在两种语言中，两个词的原型义都是“火或血的颜色”，虽然语义扩展的路径基本相同，不同的文化视角使两千词的语义产生了差异。颜色词通过表达相应的颜色概念，把客体，颜色和主体三方面联系在一起，使颜色词不仅指称了颜色概念所表达的客体方面的特征，而且还表达了颜色在人的主体方面所能引起的一切刺激反映的特征。     

城市污染源S0_2扩散规律研究

通过剖析几种常用大气污染物扩散模式,选取合适的大气扩散场参数,建立了适用于郑州市区的污染源SO2扩散模式。用该模式计算市区重点污染源典型月所排SO2浓度,其结果与实际监测结果进行对比分析,对比结果表明,在采暖期和非采暖期两个典型月的相关系数分别为0.727和0.713,达到显著水平。

PDE-Based Medial Axis Extraction and Shape Manipulation of Arbitrary Meshes

Shape skeletonization （i.e., medial axis extraction） is powerful in many visual computing applications, such as pattern recognition, object segmentation, registration, and animation. In this paper, the authors expand the use of diffusion equations combined with distance field information to approximate medial axes of arbitrary 3D differential properties. It offers an alternative solids represented by polygonal meshes based on their but natural way for medial axis extraction for commonly used 3D polygonal models. By solving the PDE along time axis, this system can not only quickly extract diffusion-based medial axes of input meshes, but also allow users to visualize the extraction process at each time step. In addition, the proposed model provides users a set of manipulation toolkits to sculpt extracted medial axes, then use diffusion-based techniques to recover corresponding deformed shapes according to the original input datasets. This skeleton-based shape manipulation offers a fast and easy way for animation and deformation of complicated mesh objects.     

Systemic Intervention in a University Department: Reflections on Arrested Action Research

This paper reflects on my experience as an insider researcher attempting to use critical systems ideas and practices to promote quality improvement in a university engineering department. Reflection is a key part of learning. This paper is intended to contribute to critically, self-reflective learning for the community of systems practitioners. These reflections on my questions about participation, ethics, politics of process, and the choices and actions resulting from them may help others to formulate their own. The complexity of systems practice places substantial demands on the researcher, particularly in the case of insider, practitioner research. Nevertheless, the exploration of critical systems approaches to critique boundaries and structure ‘problems’ in the core aspects of higher education in locally meaningful ways should continue. While demanding, it still can work to promote learning about authentic quality.     

20世纪60年代黑人利益集团的崛起与美国政府的应对——“最后通牒”博弈理论的分析

从博弈论的角度论述了20世纪60年代发生于美国的以黑人利益集团为主体的争取自身利益的活动，以及美国政府所作出的回应。最终得出黑人利益集团在60年代末走向没落的根本原因在于他们最终的愿望是想要融入美国社会，而由于自身的经济条件不发达，以至于在博弈中处于被动地位，并最终销声匿迹。

PEAK COVARIANCE STABILITY OF A RANDOM RICCATI EQUATION ARISING FROM KALMAN FILTERING WITH OBSERVATION LOSSES

We consider the stability of a random Riccati equation with a Markovian binary jump coefficient. More specifically, we are concerned with the boundedness of the solution of a random Riccati difference equation arising from Kalman filtering with measurement losses. A sufficient condition for the peak covariance stability is obtained which has a simpler form and is shown to be less conservative in some cases than a very recent result in existing literature. Furthermore, we show that a known sufficient condition is also necessary when the observability index equals one.
