正世界水族馆大约500万年前,频繁的地震和火山活动撕裂了墨西哥大陆的西部,形成了加利福尼亚半岛和本土间的巨大鸿沟,太平洋海水灌入,从而产生了如今的科尔特斯海(Sea of Cortez),又叫加利福尼亚湾(Gulf of California);持续的火山喷发形成了科尔特斯海中诸多的小岛。墨西哥征服者埃尔南·科尔特斯听闻这座海域的岛上遍地黄金,海里到处是珍珠,于是派遣了弗朗西斯科·乌略亚前去勘探,结果自然是没有找到珍宝,不过乌略亚还是用他上司的名字——科尔特斯命名了这片海域。 相似文献

AbstractIn 1981 the four space agencies Intercosmos, ISAS, NASA and ESA formed the Inter-Agency Consultative Group for Space Science (IACG). The objectives of the IACG are to maximise opportunities for multilateral scientific coordination among approved space science missions in areas of mutual interest. The IACG is a multi-agency international forum in which space science activities are discussed on an informal basis among representatives of the member agencies. It concentrates on a single discipline area of approved space science projects as a focal point for a number of years. Until 1986 the IACG coordinated the six space missions to Halley's Comet: Vega 1 and Vega 2 from Intercosmos, Suisei and Sakigake from ISAS, ICE from NASA and Giotto from ESA. Since 1986 the IACG has been coordinating 13 projects involving 20 spacecraft in solar–terrestrial science. 相似文献

Studies of gender have an important place in studies of Turkey because the discourses of Islamism and secularism, and modernity and tradition, make the bodies and practices of Turkish women the site of debate. However, few studies have used a spatial analysis to examine the production of gender in daily life. This article is simultaneously a study of how gender is produced through space and of the creation of various kinds of spaces in an Istanbul mahalle (neighborhood). The mahalle is the space of intimate daily life in the Turkish urban context, and narratives of and ways of life in the mahalle articulate competing notions of what it means to be a woman in Turkey. This study of gender and mahalle space reveals the linkages between space and gender to be multiple and shifting and the boundaries between private and public spaces to be fluid. Furthermore, this reading of gender and urban space, when brought back to the Turkish context, also contributes to research which interrogates the idea of modernity at the core of national identity in Turkey, of which gender is a central and constitutive element. 相似文献

The extensive restructuring of industrialized economies continues to challenge workers and their unions in the 1990s. Labor unions are trying to remain viable institutions in the face of globalization of economic production, deindustrialization, and technological change. These processes have increasingly challenged workers in traditionally highly unionized sectors of the economy such as manufacturing and resource extraction industries. At the same time, unions have failed to organize large numbers of workers, often young and female, in geographically fragmented workplaces in expanding sectors of the economy such as consumer services and subcontracted goods production. There has been a call for new "spatialized strategies" allowing unions to access these new sectors and spaces and to produce scales of organization compatible with post-industrial capital. One strategy being adopted by the labor movement is coalition building with non-labor community interest groups with common goals in order to shape geographies of production. The experience of two Canadian unions with "community unionism" is discussed as an example of a spatialized strategy still in early development. 相似文献

20世纪50年代,我国内地基本建设投资的前提是:生产力水平低下,人均产值低;资金紧缺,但资产相对集中;西方国家对我国实行经济封锁;我国确立了优先发展重工业的工业化方针.通过对我国经济建设投资的产业结构、区域布局、项目结构、主体结构的分析,我们可以得到几点启示:投资管理体制的变化要适应生产力发展的要求;建设规模不能超过国力许可的范围,急于求成必将适得其反;综合平衡应从短线出发. 相似文献

AbstractThe era of manned spaceflight began in the early 1960s. Now, only a quarter of a century later, the foundation is being laid for permanently manned space stations which, a century ago, were the domain of visionaries whose dreams of space habitats and their uses were not that far away from current plans. The first space stations were the Soviet Salyut 1 and the American Skylab of the early 1970s. The Russians built a succession of Salyuts, the last of which was Salyut-7, launched in 1982. This was succeeded in 1986 by Mir, to which a first expansion module has already been added. Mir is planned to become a multimodule facility. The Americans have chosen a different path to their space station. From 1975 to 1981, they developed their Space Transportation System (Space Shuttle) of which Spacelab is a part. Built by Europe and flown first in 1983, it is the world's only reusable, manned space laboratory. The Space Shuttle is to be the logistics vehicle for the US-directed International Space Station, which includes cooperation from Europe, Japan and Canada. As currently planned, the ISS will consist of a rectangular framework of trusses at the center of which will be a core of laboratory, habitation and logistics modules. Unattached space station elements are to include polar-orbiting platforms and a co-orbiting, automated laboratory. 相似文献

The history of modern and contemporary Italy: Made in France (from the late 1970s to the late 1990s)
Olivier Faron 《Journal of Modern Italian Studies》2013,18(3):416-440
Abstract Over the past three centuries Italy has been the focus of numerous studies by French historians, who have taken advantage of the great wealth of sources available there. While no new synthesis has yet been achieved, we can identify certain main lines of development in French historiography. In the late 1970s and into the 1980s international relations and, especially, the relations between France and Italy were given the greatest attention, before a new focus on forms of sociability and political pedagogy began to be more common. However, the shifting of focus of historical studies to the centres of political decision making often coincided with less attention being paid to social stratification. Beyond these major themes, some researchers have reconstructed ‘global’ historical models, which have been characteristic of the renewal of post‐war French historiography. 相似文献

AbstractFor fifteen years from 1962–1977, scores of artists have walked among the launch pads, conversed with astronauts, space scientists and technicians, taken make-believe rides to the Moon in a simulator, were as close as safety allowed to the space launches, and waited for weeks in mid-ocean aboard an aircraft carrier for the return of the Moon explorers. The author directed this unique art program for almost all the time it was in existence and here reviews its philosophy, the interrelationships between engineers and artists, the difficulties that arose and the rewards which accrued. 相似文献

A new and recursive algorithm for determining proximal polygons is based on quadtree concepts. The algorithm can use any distance metric, and produces a quadtree of the image of the proximal polygons. This can be converted to vector form, or be incorporated directly into a quadtree-based geographic information system, in order to solve a number of closest-point problems. The algorithm can also produce the Delaunay triangulation, which is the dual of the proximal polygons. Empirically, the running time of the algorithm is proportional to the number of centers raised to the 1.6 power. 相似文献

It is now commonly accepted that technology is, to its very core, a social product through which we can explore cultural choices. This cultural dimension of technology will be examined with reference to the introduction and use of the potter’s wheel at Phylakopi on Melos (Greece) during the Late Bronze Age. At this site, the co-existence of two different manufacturing techniques was so deeply embedded that, despite the presence of hybrid vessels, many aspects of the pottery production had become linked to either a local (hand-built) or Minoanising (wheel-thrown) tradition. It will be argued that the traditional hand-building technique was associated with individual and rooted facets of the Melian identity (such as kinship, social class, or gender). Reasons for the initial stimulus for adoption of the potter’s wheel are considered to lie in its potential for competitive social practice through association with exotic, symbolically laden technologies, craft products and consumption rituals. The gradual application of the technology to ever more complex vessels, on the other hand, corresponds to the apprenticeship sequence outlined by Roux and Corbetta and may indicate an incomplete learning process or a certain lack of practice opportunities among local potters. 相似文献

论文论述了20世纪六七十年代美国华裔青年"新左派"团体产生的社会政治背景,华裔青年新左派团体的兴衰与转型。论文认为,华裔青年新左派团体作为亚裔美国人运动一支不容忽视的力量,从校园斗争转向唐人街,开展"草根阶层"运动和"为人民服务"行动,力图发动普通华人向不平等、不公正的社会制度发起挑战,争取应得的平等权益。他们的努力确实取得了一定的成效,让唐人街失学的青少年、失业的劳工、贫困的租客等获得了一些教育、就业、医疗等方面的福利。但是,这些左翼团体主张以"革命斗争"推翻美国政府,脱离了社会实际,因而得不到大多数华人的认同,有的只维持几年就解散了,有的转向"温和",接受了美国主流政治的游戏规则。虽然受特定时代思潮的影响,有一定的"局限性",但其在美国华人民权运动史上的贡献不应被遗忘。正是他们无私无畏的斗争,并发挥教育和引领的作用,才使得普通华人民众的维权意识得以提升,给相对保守"沉默"的华人社区带来一股革新之气。 相似文献
