优化高校第二课堂推进当代中国马克思主义大众化

高校在推进当代中国马克思主义大众化进程中担负有重要的历史使命。高校第二课堂对于推进当代中国马克思主义大众化有明显的优势。优化高校第二课堂活动的组织实施,使其成为高校推进当代中国马克思主义大众化的新载体和新方法,具有重要意义。     

Beam steering in planar photonic crystal based on its anomalous dispersive properties

INTRODUCTION Photonic crystals (PhCs) are increasingly at- tracting attention due to their ability of controlling light propagation on a wavelength scale, by which a fascinating platform for a new generation of inte- grated optical devices and components can be pro- vided. Many studies on PhCs however, focused on new means of tailoring the emission and propagation of light using the photonic band gap (PBG) property whereby the photon density of states is zero. A PhC with a full PBG re…

The reading efficiency model: an extension of the componential model of reading

The purpose of the present study was twofold: First, the authors investigated if an extended version of the component model of reading (CMR; Model 2), including decoding rate and oral vocabulary comprehension, accounted for more of the variance in reading comprehension than the commonly used measures of the cognitive factors in the CMR. Second, the authors investigated the fitness of a new model, titled the reading efficiency model (REM), which deviates from earlier models regarding how reading is defined. In the study, 780 Norwegian students from Grades 6 and 10 were recruited. Here, hierarchical regression analyses showed that the extended model did not account for more of the variance in reading comprehension than the traditional CMR model (Model 1). In the second part of the study the authors used structural equation modeling (SEM) to explore the REM. The results showed that the REM explained an overall larger amount of variance in reading ability, compared to Model 1 and Model 2. This result is probably the result of the new definition of reading applied in the REM. The authors believe their model will more fully reflects students' differentiated reading skills by including reading fluency in the definition of reading.     

美国加州:阳光照耀的留学生活(三) 母语和韩国白领李尚美

与此女的认识过程显然要轻松许多,原因是我能够在一定程度上使用她的母语。除了课堂以外,和她一起工作的经历,也成了我宝贵的留学回忆。她便是赴美进修的韩国白领李尚美。     

基于扩散几何坐标的高光谱影像的增强表示(英文)

利用扩散映射所诱导出的扩散几何坐标对高光谱影像低维可视化表示,这种非线性维度约简的表示方法能够得到高光谱影像紧凑而富含信息量的可视化表示结果.通过对海量高光谱影像中每个高光谱观测向量进行局部搜索,仅考虑局部的邻接性和局部的相似度,构造出该高光谱影像对应的近邻图;对近邻图进行合适的规范化,得到该高光谱影像对应的扩散算子,相当于利用该扩散算子对高光谱特征空间模拟出马尔可夫随机游走.因此这样的构造较好地把握了高光谱影像内蕴的几何信息,与传统的基于主成分分析的线性降维表示方法相比,由扩散算子的特征分解所诱导出的扩散几何坐标能够给出更好的表示效果,富含更多的信息.对于大尺度的全景高光谱影像,利用构造"骨干"扩散几何坐标系的方法,其计算的时间复杂性和空间需求都是可接受的.实验也表明,选择合适的对称化方法规范扩散算子对于最终的高光谱影像表示有重要的影响.

The most amazing 24 hours

In this column, a mother shares the story of her son's birth with her prenatal yoga instructor. The mother was able to work with her labor, was well supported by her husband and doula, and negotiated successfully with the hospital staff to have a safe, healthy birth. She describes how difficult labor is and the ways in which comfort and support strategies help women manage contractions.

我的案子归哪个法院管——法院管辖之地域管辖

<正>地域管辖,就是按照人民法院的主管范围和当事人住所地来划分同级人民法院之间审判第一审民事案件的权限。级别管辖是确定民事案件第一审由哪一级人民法院审判,而地域管辖则是在确定级别管辖之后,再确定由哪个地方的人民法院管辖。所以,只有根据地域管辖的规定,才能确定案件由哪个地方的人民法院受理、审判。
