基于未确知数学在工程管理中的应用研究

随着我国经济的不断发展,我国的市场化经济不断的完善,国民经济总量已经超过日本,成为全球第二位,经济的发展使得各行各业都得到了十分迅速的发展,作为传统行业的建筑业也同样发展迅速。对于建筑业的工程管理来说,有许多的问题都是不确定,具有很多变化的,因此为了对这些问题进行研究和解决就需要使用到未确知数学的知识,以便能够更好的解决问题,提高建筑工程管理的质量和效率。本文主要对什么是未确知数学以及未确知数学在工程管理中的具体应用进行研究。

Students' Reactions to the Introduction of Videoconferencing for Classroom Instruction

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors.     

孵化器与风险投资融合模式研究

近加年来,世界各国为了推动高新技术产业的发展,普遍采用孵化器与风险投资融合的模式.孵化器和风险投资在形成的背景、追求的价值、主要的服务功能、关注的空间和时间形态上有所不同,但在发展方向、运行模式、投资领域的专业化和退出方式上存在着很多的共同点,并且在项目源、管理、资金和政策上存在着很强的互补性,两者的融合将是"双赢"或者"三赢"的结果,融合非常必要,彼此都有融合的利益和风险.因此,二者的融合成为一种必然的趋势,也必定能促进风险投资和孵化器的共同发展,寻求它们之间的融合机制也变得越来越重要.     

家用喷墨打印机的日常维护和常见故障检修

维修打印机之前需要对打印机出现的问题有一些了解。打印机出现问题后，首先是利用打印机自检系统进行检测，通过打印机自带的指示灯或者是蜂鸣器的声音来加以判断：其次，可以进行线路观察，看部件是否正确工作，针对不同的故障情况锁定相关的部件，再确定存在问题的部件；再次，可以使用测试法，进行测试页打印或者局部测试打印机内部件，查寻故障原因。     

基于旅游者视域的旅游可持续发展路径探析

本文以甘肃旅游开发为例,通过对来访甘肃的旅游者的意识进行问卷调查,并运用赫茨伯格的“双因素”理论等相关理论对旅游者的满意与不满意要素进行深入分析,揭示旅游发展中存在的问题,从旅游者的视角对旅游可持续发展的影响要素进行深入探析,并基于此提出相应解决对策。本研究重点为分析旅游的满意要素和不满意要素,并进一步探讨旅游的满意要素和不满意要素与旅游可持续发展的关系,明晰旅游的满意要素（即软件）的不断充实和完善才是真正推动旅游可持续发展的关键所在。     

西方可持续性理论研究的最新进展及其趋势

Rough Justice: A Statistical Assessment of ICANN's Uniform Dispute Resolution Policy

Long-standing conflict between domain name registrants and trademark holders prompted the Internet Corporation for Assigned Names and Numbers (ICANN) to create a global, mandatory arbitration procedure known as the Uniform Dispute Resolution Policy (UDRP). The UDRP has been used in 2166 cases involving 3938 domain names as of 1 November 2000. The policy gives the initiator of a complaint, generally a trademark holder, the right to choose which ICANN-accredited dispute resolution service provider (RSP) will handle the case. During the preparation of the UDRP,some feared that complainant selection would lead to "forum shopping" that might bias the results. This article performs a statistical assessment of the forum-shopping thesis and finds support for it. There are statistically significant differences in the various RSPs' propensity to take away names from defendants; there are also major differences in the number of cases brought to each RSP. RSPs who take away names have the larger share of cases. The study examines other variables that might explain differences in market share, such as price, the plaintiff's nationality, or the time taken to decide a case. It finds that nationality and time also are correlated with market share. The study concludes that shopping for a favorable outcome is an important factor in the UDRP.     

Rethinking Universal Service: Citizenship, Consumption Norms, and the Telephone

One of the reasons the proponents of expanded universal service have not made much headway is that they have not been able to provide a coherent justification for the major resource and policy commitments it requires. The lack of consensus on the very meaning of the term "universal service" has added to the confusion. This article argues that it is critically important to articulate a clear justification for universal service before we discuss what it should include and how it should be funded, the two main preoccupations of the current debate. It answers the "why" question by drawing on the literature on consumption norms and citizenship rights and thereby provides a cogent justification for universal service. A clear articulation of the rationale for universal service should reduce some of the confusion in the current debate and bring greater clarity to the ongoing debate on this important public policy issue.     

百分位数指标的修正及评价分析

针对相对影响和百分位数指标的局限,提出修正百分位数指标。从引文量分布特征、同区引文量差异、引文量与发文时长关联性等方面,对相对影响和百分位数指标进行了对比分析。在此基础上,将相对影响和百分位数指标融合并引入时效性参数,构建了修正百分位数指标并以图书情报类核心期刊及高校图书馆作为测评对象进行了案例分析。结果表明,修正百分位数指标可将位于同一百分位区间但发文时长及引文量不同的论文纳入到同一尺度下进行对比评价,测评结果对于引文数量特征和内在规律性的反映更为客观。     

基于h指数、g指数和p指数的微博影响力评价对比研究

考虑到微博与传统文献的相似性,本文旨在探索h指数、g指数和p指数在微博影响力评价中的应用,通过对比三者的评价结果来探索3种指数在微博影响力评价上的合理性和各自的特点。首先,基于信息计量领域中的h指数、g指数和p指数的定义,针对微博转发数、评论数和点赞数构建9项微博影响力评价指标;然后,以40所"双一流"高校的微博为实证对象,通过整体对比、相关性分析等方法,将h指数、g指数和p指数对微博影响力的评价结果进行了对比。结果表明3个指数在微博影响力评价中都有一定合理性;在区分度方面,g指数和p指数都优于h指数,其中,p指数最具优势,并能挖掘高影响力的非活跃用户;在敏感度方面,h指数不易受极端值影响,更适合评价微博影响力。     

Deep Sleep in the Arctic

Saving energy is crucial to the survival of animals living in the cold regions of the world. A small marmot-like rodent from the Arctic is world champion when it comes to energy saving. According to YAN Jun from the CAS-MPG Partner Institute for Computational Biology in Shanghai, this makes the Arctic ground squirrel extremely suitable for studying the changes that occur at the molecular level during rodent hibernation. Based on this, the scientist and his colleagues aim to discover exactly how the animals can attain such dramatic reductions in their metabolic activity.
