构建面向宏观调控的决策支持系统

面对宏观经济各种运行态势，政府将采取不同的宏观调控手段以保持经济长期稳定、健康发展。本文针对政府制定宏观调控政策的工作任务，分析了面向宏观调控决策过程的基本需求，构建了一个基于数据仓库的宏观调控决策支持系统的框架。该系统的主要特点是在数据挖掘和文本挖掘的基础上，进行数据分析和指标预测，从经济周期的完整过程对宏观调控政策效果予以评价，从而为宏观调控政策的选择提供参考。     

科技进步与经济周期

作为一名传统经济周期理论学家之一,希克斯也是通过乘数-加速数原理的相互作用来解释经济周期问题的。对于希克斯的经济周期理论,西方经济学家给予了很高的评价。直到现在为止,一些西方经济学家仍然认为:“在某种意义上说,希克斯的模型保留了经济周期理论权威性的语言。”     

新经济增长点与可持续发展

改革开放18年来,我国经济一直处于快速增长阶段,人均国内生产总值增长了三倍。与此同时,由于近两年来中央坚持采取“适度从紧”的宏观调控政策,通货膨胀亦得到有效的抑制,今年可望实现预期的调控目标。在“九五”开局良好的形势下,为了促进实现“两个转变”,确保经济持续、快速、健康发展,选择新的经济增长点,已成为人们共同关心的问题之一。但这一问题应该从经济可持续发展来考虑。     

老年人同居——一种新的社会现象

作为一种新的社会现象，老年人的同居不能简单地判断其“是”与“非”，或者“应该”与“不应该”，而应当站在老年人的立场上，从他们的生活处境和实际状况去理解。     

县际竞争、县际竞合与区域经济协调发展

县域经济差异是区域经济发展过程中广泛存在的现象,其发展变化对区域经济发展产生着重要影响.通过县际竞争中区域经济增长的研究视角,以县际竞争为出发点,通过博弈模型来探讨县际竞争演进趋势,并结合宁波水权交易案例分析,研究结果表明作为中国经济增长源泉的县际竞争最终应该实现县际竞合,认为可以通过建立县域间有效的“利益分享机制”和“利益补偿机制”,实现县际经济增长进而促进区域经济协调发展.

“扩权强县”改革对不同类别县域经济绩效的影响——来自四川省59个试点县的经验证据

利用四川省59个试点县2005 ～2014年的经济社会数据,借助“准自然实验”倍差估计法和面板虚拟变量模型分析了“扩权强县”改革对不同类型县域经济绩效的影响,发现:按地理区位划分的丘陵县较山区县和平原县而言,在促进地方经济增长尺度上更易受到“扩权”试点的红利作用,而平原县和山区县则主要凭借经济管理权下放获取更强的本地产业结构优化效应.若按经济类型划分,选择百万人口大县进行扩权试点比选择农业大县会带来更加显著的政策带动效果.

寻求社会公平

人们对于社会现实的公平或不公平的价值判断,会影响到他们的社会政治态度。各个社会阶层的人,由于所处的社会经济状态不同,对于社会现实的价值判断也会有所不同。经济改革以来,中国社会的收入差距持续拉大,社会公平问题引起广泛关注,并激起部分人群的不满情绪。是什么导致不公平?根据中国社会科学院社会学研究所“当代中国社会结构变迁研究”课题组的一项全国抽样调查数据,目前大多数人认为,权力、职业和行业是导致当前中国社会不公平现象的主要因素。大约6/10的人(61.5%)选择“因权力造成的不公平”作为当前中国社会最主要的3种不公平现象…     

基于县级城市的城乡一体化是我国城市化道路的一种政策选择

现阶段严重的收入和地区不平等、大城市具备良好的自我发展能力、城市倾向的制度根深蒂固等现实决定了以大城市作为城市化的“政策主导”既不应该也无必要,否则既不公平也很危险;不以大城市作为“政策主导”并不否定大城市的“主导地位”;小城镇发展的实践、人多地少的国情和小城镇缺乏集聚经济、规模经济等因素决定了以小城镇为“政策主导”也不可行;县级城市作为联系城乡的关键节点和兼顾城市化与城乡一体化、兼顾效率与公平的重要切入点,应当得到政策上的重点倾斜,这具有多方面的优势,适宜在政策上成为“十二五”时期中国城市化道路的一项战略选择,但同时也应避免“一刀切”,注意具体措施的因时、因地制宜.     

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.     

Cooler temperatures inductive to locust outbreaks

The study was published in Proceedings of theNational Academy of Sciences on 17 September, 2007.     

Exploring Multiplexity: Social Network Structures in a Computer-Supported Distance Learning Class

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction.     

The Role of Intermediating Institutions in the Diffusion of Electronic Data Interchange (EDI): How Industry Associations Intervened in Denmark, Finland, and Hong Kong

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies.     

How Electronic Publishers are Protecting Against Piracy: Doubts About Technical Systems of Protection

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means.     

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.

Monoculture Rubber Plantations Have Negative Ef ects on Controlling Splash Erosion

<正>In Xishuangbanna,one of China’s most biodiverse regions,landscape has changed dramatically during the past three decades due to the conversion of tropical rainforest to rubber plantations.In steep areas,terraces are often constructed before planting rubber trees,which causes two important changes in the soil:the destabilization of soil in the bench terraces and the increased vulnerability of unvegetated riser faces to erosion.Few studies have documented the nature and intensity of erosion on bench terraces.Prof.LIU Wenjie and his colleagues from the Xishuangbanna Tropical Botanical Garden(XTBG)conducted a study in Menglun County(21°5′39″N,101°15′55″E),Xishuangbanna to evaluate the influence
