Engaging Undergraduates in Science Research: Not Just About Faculty Willingness

Despite the many benefits of involving undergraduates in research and the growing number of undergraduate research programs, few scholars have investigated the factors that affect faculty members’ decisions to involve undergraduates in their research projects. We investigated the individual factors and institutional contexts that predict faculty members’ likelihood of engaging undergraduates in their research project(s). Using data from the Higher Education Research Institute’s 2007–2008 Faculty Survey, we employ hierarchical generalized linear modeling to analyze data from 4,832 science, technology, engineering, and mathematics (STEM) faculty across 194 institutions to examine how organizational citizenship behavior theory and social exchange theory relate to mentoring students in research. Key findings show that faculty who work in the life sciences and those who receive government funding for their research are more likely to involve undergraduates in their research project(s). In addition, faculty at liberal arts or historically Black colleges are significantly more likely to involve undergraduate students in research. Implications for advancing undergraduate research opportunities are discussed.     

写作:作者与写作对象及阅读者的话语交流

写作的过程也是一种对话的过程。写作因话语交流而实现了价值的最大化。"话语交流式"作文的本质就在于促使写作者与写作对象、阅读者建立相互依赖、相互作用的主客体结构,努力唤醒写作者的主体意识,使写作者在双向或多向的沟通交流中,能真实、自由、个性化地表达,以提高驾驭语言的能力,促进写作智能的发展,达到"自能"作文的境界。本文试从"话语交流式"作文的具体内涵、现实意义及实施的策略方面分述之。     

内蒙古新时期风情性草原题材绘画探析

内蒙古新时期草原题材绘画不同于20世纪五六十年代的主题性绘画,主要表现为风情性。一大批优秀的画家创作出了享誉国内外的优秀作品。他们以现实主义为主要创作方式,不断探索新的表现形式和绘画语言,对草原风情及其背后的深层民族文化精神进行挖掘,体现出从民族风情到民族精神的渐趋深化的历程。     

英语否定转移的表达方式及其汉译

否定转移是指位置上与一个词或短语放在一起的否定词,有时在意义上或逻辑上可转移到去否定另一个词或短语。通过总结英语否定转移的四种表达方式,即从一般否定转移到特指否定;从特指否定转移到一般否定;从一种特指否定转移到另一种特指否定;从否定主句谓语动词转移到否定从句谓语动词,来探讨其在汉语中的翻译,以期进一步提高翻译的准确性。     

Ranking scientific articles based on bibliometric networks with a weighting scheme

As the volume of scientific articles has grown rapidly over the last decades, evaluating their impact becomes critical for tracing valuable and significant research output. Many studies have proposed various ranking methods to estimate the prestige of academic papers using bibliometric methods. However, the weight of the links in bibliometric networks has been rarely considered for article ranking in existing literature. Such incomplete investigation in bibliometric methods could lead to biased ranking results. Therefore, a novel scientific article ranking algorithm, W-Rank, is introduced in this study proposing a weighting scheme. The scheme assigns weight to the links of citation network and authorship network by measuring citation relevance and author contribution. Combining the weighted bibliometric networks and a propagation algorithm, W-Rank is able to obtain article ranking results that are more reasonable than existing PageRank-based methods. Experiments are conducted on both arXiv hep-th and Microsoft Academic Graph datasets to verify the W-Rank and compare it with three renowned article ranking algorithms. Experimental results prove that the proposed weighting scheme assists the W-Rank in obtaining ranking results of higher accuracy and, in certain perspectives, outperforming the other algorithms.     

基于稀疏求解的改进PCA方法在SAR目标识别中的应用

针对实际军事情况下车辆目标为非合作目标,提出改进的主成分分析方法（IPCA）。它首先利用稀疏求解方法得到与测试样本最相关的部分训练样本以及它们对测试样本的表示系数。然后结合主成分分析（PCA）得到最优投影矩阵,使投影后不同测试样本能更好地利用训练样本信息进行分类。利用美国运动和静止目标获取与识别数据库中3类目标进行识别实验,结果表明基于改进的PCA方法比传统的PCA方法能够得到更高的识别率,并对稀疏方位角训练样本有更好的鲁棒性。     

基于特征筛选和二级分类的极化SAR建筑提取算法

提出一种基于特征筛选和二级分类的建筑提取算法。该算法首先对极化SAR数据进行精致Lee滤波,获取多维极化特征和纹理特征构成原始特征集;然后将随机森林作为初级分类器评估各特征的重要性,依据重要性排名进行特征筛选;最后通过支持向量机对特征子集进行次级分类,并用邻域投票法将两级分类结果融合。AIRSAR极化数据实验结果表明,本算法可有效提高极化SAR建筑提取准确率。     

论中华武术文化对提升高等学校文化发展的作用

武术文化既具有体育活动强身健体的特征,又蕴涵中华文化独特内涵和民族文化特征。武术的社会价值和锻炼价值十分丰富,对人产生了深远的影响。文章通过研究优秀的民族传统体育项目在高等学校的普及,指出它有助于民族文化的传播和继承,对发扬民族优秀品质,振奋民族精神,崇尚社会文明将会产生重要的作用。     

高职高专院校学生体质健康状况的调查与分析

运用文献资料法、体质测试法和数理统计法,对2006—2010年晋城职业技术学院学生体质健康状况进行比较分析。结果发现：学生体质健康状况总体上呈现出下降的趋势,随着年限和年级的增长,下降的趋势更加明显。学校的体育教育在做好技能传授的同时,应加强身体素质的练习,从而改变其下降的趋势。
