AbstractThe collection of essays introduced in this article contributes to the debate on the commercialization of academic science by shifting the focus from institutional developments meant to foster university technology transfer to the actions of individual scientists. Instead of searching for the origins of the ‘entrepreneurial university,’ this special issue examines the personal involvement of academic physicists, engineers, photographic scientists, and molecular biologists in three types of commercial activity: consulting, patenting, and full-blown business entrepreneurship. The authors investigate how this diverse group of teachers and researchers perceived their institutional and professional environments, their career prospects, the commercial value of their knowledge and reputation, and their ability to exploit these assets. By documenting academic scientists’ response to market opportunities, the articles suggest that, already in the decades around 1900, commercial work was widespread and, in some cases, integral to academics’ teaching and research activity. 相似文献

Investigations at the Carson site (22CO505), located in Coahoma County, Mississippi, have uncovered data on the development of a large Mississippian mound center dating to the period from A.D. 1200 through European contact. Recent sediment coring, excavation, artifact analyses, and radiocarbon and optically stimulated luminescence (OSL) dating shed light on earthworks and household structures at Carson, and on Mississippian culture in the Yazoo Basin more generally. Sediment coring demonstrates a laterally transgressing Mississippi River system deposited coarse sandy ridges and clay-filled swales underneath a surface horizon comprised of variously coarse to medium-fine sediment originating from generalized overbank flooding. In some instances, flood-borne sediments were found on mound flanks, indicating that at times river-based flooding may have interrupted mound construction. Sediment coring and trench excavation also demonstrate that Carson’s Mound D was built in four stages, with Stages II and III comprising the major stages of earth moving. Excavations on the mound summit reveal evidence of several superimposed structures that were burned in place and likely used for the production of stone, shell, and wooden craft items, perhaps related to Mississippi Ideational Interaction Sphere (MIIS) paraphernalia. Here we describe recent investigations at Carson and present preliminary findings; forthcoming publications will emphasize strategies of power, monumentality, craft production, and Mississippian exchange systems. 相似文献

The putting-out spinning of flax for merchants and weaving of kersey in house-manufactories for export are examples of new elements in wool production and manufacturing in late 18th-century Iceland. The import of luxuries also increased, and a broader group of inhabitants acquired these items from the monopoly-trade merchants. The article analyses how these elements can be understood in light of Iceland’s pre-industrial society. How did these changes become visible and have an impact on the country? Did changes in wool production and consumption signify new trends in 18th-century society, or should one interpret them as extensions of structures that already existed within what can be called the ‘Old Society’? 相似文献

The recent discovery of banana phytoliths dating to the first millennium BC in Cameroon has ignited debate about the timing of the introduction of this important food crop to Africa. This paper presents new phytolith evidence obtained from one of three sediment cores from a swamp at Munsa, Uganda, that appears to indicate the presence of bananas (Musa) at this site during the fourth millennium BC. This discovery is evaluated in the light of existing knowledge of phytolith taphonomy, the history of Musa, ancient Indian Ocean trade and African prehistory. 相似文献

新世纪以来中德世界城市全球化模式对比分析 总被引:1,自引:0,他引:1
城市全球化逐渐从跨国资本主导下的单一化模式向国家特性作用下的多元化发展转变。本文对比分析了新世纪以来中国和德国世界城市全球化的过程、格局、规模、产业和动力,揭示出国家特性作用下的差异化城市全球化模式。结果表明:①中国城市全球化起步较晚但发展迅速。②中国世界城市呈现“大分散,小集聚”的格局,全球化要素具有分散化趋势。③中国世界城市经济的总量大但平均规模小,企业总部集中分布于北京。④中国世界城市一、二次产业产值比重大,金融地产、社会公共服务业和总部经济发展滞后。⑤中国城市全球化是国家政府主导下依托跨国投资生产并出口初级工业品的被动全球化,未来须发挥高级生产者服务、研发服务和社会服务的动力作用。 相似文献

A U.S.-based geographer and specialist on China advances his research on industrial districts and regional development by presenting a 2008 study of shoe manufacturing in Wenzhou (a major center in the world's largest footwear producing and exporting country). More specifically, the author examines how the model of economic development pioneered in Wenzhou (the Wenzhou model) has been transformed in an effort to meet the challenges posed by the global economy. He argues that the scaling up of Wenzhou's footwear industry, through the expansion of sales networks and factories across China and abroad, indicates that other adaptable city regions can overcome similar obstacles. The author challenges both the New Regionalism literature focused on local institutions and assets, as well as perspectives that overemphasize the benefits of globalization and global production networks.

20世纪中国的社会转型与社会变革的两种思想和方式 总被引:1,自引:0,他引:1
在20世纪中国社会转型的过程中,革命与改良(改革)这两种变革思想和方式之间虽然有重大区别,但又是互补的,而且"你中有我,我中有你".两者在不同的历史时期各凸现其主导功能,也会相互转化,不可绝对地厚此薄彼,更不可只肯定一种而否定另一种.事实上,革命与改良是同一部乐曲的"双重变奏",两者的相生相克、相辅相成、交互辉映,共同组成了20世纪中华民族救亡图存、启蒙大众、革故鼎新的历史画卷,共同推进了中国社会的现代化.20世纪最后20多年的改革和发展趋势表明,中国尽管已从根本上摆脱了自我束缚的困扰,但进入新世纪后最需要的是居安思危,力戒盛世意识,增强忧患意识. 相似文献

Skill is a challenging topic for archeologists because it requires balancing the biases of cultural relativity with the commonsense
understanding that some humans are more able than others. Using the content and results model of technology, this paper identifies
skill as a variable of technological knowledge with recognizable material results. Late Paleolithic Japanese blade and microblade
assemblages suggest that skill differentials exist on the cognitive, operational, and motor levels. These examples, together
with ethnoarcheological consideration of modern potters suggest material reflections of technical skill. These include regularity
in performance and product, skilled tools, and obvious signs of practice. 相似文献

本文以上海老城厢城市景观演变的历史过程为主线,分析了主导这一过程的驱动因素及其相互间的关系。在人为侵占与河浜自然属性的交互作用下,"因浜成路"一直是上海老城厢独具特色的城市扩展方式;19世纪下半叶,传统的环境基础加上西方公共卫生观念的介入,使原来民间层面上的"因浜成路"发展为官方主导下的"填浜筑路",主干河浜消亡的速度骤然加快。这虽然局部改善了老城厢的市容与卫生状况,却对整体的水网生态和后来的城市环境造成了不利影响。这一过程中的内在规律,恰从区域可持续发展的角度,对城市化进程中人与自然间的耦合关系和互动尺度做出了注解,因而具有一定的启发意义。 相似文献
