冯至与穆旦的智性抒情诗在新诗史上占有重要的地位.冯至的《十四行集》可以说是诗与哲学的完美结合,穆旦一生的创作都体现出理性思考的力量.比较而言,冯至的诗与现实生活保持了适当的距离,诗风温和而阔大,继承了古典诗歌的某些特征,而穆旦则完全以现代派诗人的姿态,时刻切握现实生活的脉搏,体现出难得的冷峻与深刻. 相似文献

每当提到意大利,人们就会自然地联想到有着文艺复兴摇篮之美誉的佛罗伦萨,让人流连忘返的水上城市威尼斯,令人垂涎欲滴的比萨饼,以及堪称世界足球王冠明珠的意甲。现实中,浪漫的意大利人同样赋予了汽车令人难以企及的想象力。在意大利,与久负盛名的比萨斜塔和悠久的罗马古迹齐名的还有著名的菲亚特汽车和世界第三大汽车城都灵。 相似文献

外资的进入到底是促进还是抑制了我国内资企业技术创新能力的提高?对此问题,学者们多有争论.大体有两种相反的观点:有学者认为,外资进入促进了我国内资企业的技术创新能力;另有学者认为外资的进入起了抑制的作用.本文运用1998-2003年制造业面板数据,定量地评估了三资企业的进入对我国内资大中型企业技术创新能力的影响.结论认为:三资企业对我国内资企业的技术创新能力的作用应该根据技术水平区别来看.对处于技术前沿的行业,外资的进入会使它们的技术创新能力得到提高;而技术水平相对比较落后的行业,外资的进入会使它们的技术创新能力下降. 相似文献

比赛法在乒乓球课中的应用 总被引：1，自引：0，他引：1
为解决乒乓球课运动量偏小,练习基本技术针对性、目的性不强的问题,从所任一、二年级七个乒乓球班随机选取两个班级,有组织地进行每课约40分钟的升降级比赛（二年级）和小组循环赛（一年级）,以寻求较好的比赛和教学方法。经与其他五个班级比较,该两个班在学习基本技术的自觉积极性、目的性方面更强,技术练习的质量更趋向于实战。在约四十分钟的比赛中,运动量明显较之其它班级更大,比赛的能力要强于其它班级。比赛法较好的解决了有计划的安排比赛,以求达到有组织、有目的地提高乒乓球课的后半部分教学质量的问题。同时有效调动了学生的积极情绪,培养了良好的竞争意识。 相似文献

随着我国公路工程不断网化,沥青混凝土路面以其独有的、较好的耐久性和行车舒适性占据了公路的较大比重.但是由于各种原因,沥青混凝土路面早期破坏时有发生,有的产生横、纵向裂缝,有的局部拥包,有的产生路面汲浆、路面边部断裂、局部的沥青混凝土层剥落等,不仅影响了工程的感观质量,也影响了路面的整体性和行车的安全性,同时沥青混凝土路面的早期破坏,导致雨水的浸入渗透,使路面基层、路基遭到侵蚀、破坏和变形,加速了沥青混凝土路面的破坏,从而影响公路的使用寿命. 相似文献

提要美国内战之后,南方人通过修建的一系列的战后纪念雕塑工程来重新构建他们对战前的记忆,他们通过这种方式来维护他们之前所拥有的地方权力机构和体制。战后,南方人努力把奴隶制从他们的历史中删除,从而使他们的体制合法化,另一方面他们又向他们的接班人灌输只有相信并继续这样的文化渗透,他们原有的权利体制才不会遇到来自北方政府的质疑。 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

<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 相似文献
