对大学生"负翁"现象的思考

由于“享乐主义”等不良社会文化的影响、大学生消费心理的不成熟性以及家庭和学校对大学生消费缺乏教育和监管,导致越来越多的大学生负债消费,成为校园“负翁”。如果任其发展,校园“负翁”会给整个校园和社会带来危害。学校应采取各种措施,有针对性地对大学生进行“合理理财”和“适度消费”的教育,以培养适应时代需要的人才。     

情商对部队院校思想政治教育的启示

在军校各种事件层出不穷,传统的思想政治工作面临挑战的今天,如何应用情商理论来提高思想政治工作的实效性已是大势所趋。借鉴该理论,本文立足部队院校实际,论述情商在思想政治教育工作中的重要作用,从另一个视角对思想政治教育工作提供一定的理论借鉴。     

河南省京广/京珠沿线旅游城市带竞争力分析及对策——基于区位商理论的视角

应用区位商模型和相关分析的数学方法对河南省京广/京珠沿线的8个城市的旅游区位商进行定量分析,结果表明：郑州市、安阳市的旅游竞争力最强;新乡市、漯河市的旅游竞争力近年来增长迅速;许昌市、驻马店市、鹤壁市、信阳市的旅游竞争力较弱,河南省京广/京珠沿线8个城市的旅游竞争力从空间上呈北高南低的态势。     

产业集聚水平测度方法及实证研究——以中国纺织产业为例

利用区位商指数对中国纺织产业2003~2005年的集聚水平进行了测定。计算结果表明:我国纺织产业在东部地区如上海、江苏、天津、浙江、广东、山东等省的产业集群程度比较高;中西部地区纺织产业集聚程度相对较低;纺织产业集聚程度与工业经济增长呈现高度的正相关性;我国纺织产业集聚弹性是0.8823,该行业的规模经济效益非常明显,存在较强的规模经济效应。     

关于增广商群结构问题的讨论

Let G be a finite group, ZG its integral group ring and
n(G) the nth power of the augmentation ideal
(G), denote Qn(G) =
n(G)/
n+1(G) the augmentation quotient groups of G. In this paper we give a set of generators for
n(G) related to the Sylow p−subgroup of G. At last the structure of Qn(D2tk) for dihedral group D2tk is discussed and Qn(D2tk) ∼= Qn(D2t ) is proved.     

关于Rayleigh商迭代法的收敛性

文[1]讨论了Rayle igh商迭代法的收敛性,但在给出的说明中,对酉矩阵Q的形式提出了一些不适当的要求,额外附加了若干限制.本文改进了文[1]中关于商迭代法二次收敛性的证明.     

信息商的提出:概念及内涵

在综合现有“信息能力、信息化、信息素质”等研究成果的基础上,创新性地提出信息商概念,认为信息商就是集成了信息观、信息知识与信息能力而形成的对信息环境的适应、控制与创新能力。分析构成信息商的信息观、信息知识与信息能力三要素的关系,以及此概念的提出,对于图书馆管理与教育领域的意义。     

Normalization of zero-inflated data: An empirical analysis of a new indicator family and its use with altmetrics data

Recently, two new indicators (Equalized Mean-based Normalized Proportion Cited, EMNPC; Mean-based Normalized Proportion Cited, MNPC) were proposed which are intended for sparse scientometrics data, e.g., alternative metrics (altmetrics). The indicators compare the proportion of mentioned papers (e.g. on Facebook) of a unit (e.g., a researcher or institution) with the proportion of mentioned papers in the corresponding fields and publication years (the expected values). In this study, we propose a third indicator (Mantel-Haenszel quotient, MHq) belonging to the same indicator family. The MHq is based on the MH analysis – an established method in statistics for the comparison of proportions. We test (using citations and assessments by peers, i.e. F1000Prime recommendations) if the three indicators can distinguish between different quality levels as defined on the basis of the assessments by peers. Thus, we test their convergent validity. We find that the indicator MHq is able to distinguish between the quality levels in most cases while MNPC and EMNPC are not. Since the MHq is shown in this study to be a valid indicator, we apply it to six types of zero-inflated altmetrics data and test whether different altmetrics sources are related to quality. The results for the various altmetrics demonstrate that the relationship between altmetrics (Wikipedia, Facebook, blogs, and news data) and assessments by peers is not as strong as the relationship between citations and assessments by peers. Actually, the relationship between citations and peer assessments is about two to three times stronger than the association between altmetrics and assessments by peers.     

一类二阶非线性微分方程的振动性与渐近性

主要研究了二阶非线性微分方程（a（t）（x′（t））^σ）′＋p（x（t））x′（t）＋q（t）f（x（g（t）））=0，t≥t0的振动性与渐进性，其中σ为一个偶数与奇数的正商，得到了方程振动与渐进的充分条件，所得结果推广了文献中的相应结论。
