On December 25, 1998 the Japanese government reinterpreted a long‐standing policy prohibiting the use of outer space for military purposes by announcing its intention to develop a network of domestically produced and deployed “information‐gathering” satellites to be utilized primarily by the Japan Defense Agency (JDA) and other national security institutions. This decision is important in its own right—for one, Japan is a major player in the space technology arena—but also because of the precedent it sets for other areas of technology and military policy in Japan today. As many observers have noted, Japan appears to be undergoing a broad reexamination both of its view of the appropriate level of interaction between government bureaucracy and industry and of its military security strategy in the first decade of the twenty‐first century. The case of surveillance satellites links these two areas together, offering broader lessons for the course of Japanese policy in numerous areas in the future.  相似文献

"一带一路"战略充满各种安全风险,军事安全挑战与威胁就是其中之一。"一带一路"战略应该针对最坏的军事安全威胁来进行谋划。作为军民双用的天基资产,理应超越公共产品的范畴,承担起保护"一带一路"军事安全的重任。在可预见的未来,构筑"天基丝路"的方向是继续增加天基资产数量,促进"一带一路"沿线基础设施的互联互通;另外,从保护"一带一路"战略的军事安全来看,要增加先进侦察卫星数量,明了沿线的各种军事安全威胁;适当增加天基对地攻击武器和中远程导弹,实施快速军事反应。"天基丝路"的建设,也需要有"战略支点",即在关键地区、国家建立卫星地面站点。这又是一个棘手的政治问题,需要用政治智慧来解决。  相似文献

北京卫星城发展的问题与对策研究   总被引:2,自引:0,他引:2  
党的十六大报告提出,要逐步提高城镇化水平,走中国特色的城镇化道路。对于北京市来说,加快京郊卫星城建设,促进城乡一体化,是缩小城乡差距,缓解城市中心区人口压力,实现产业链深度整合,提高城市竞争力的一个非常重要的战略。为此,北京市总体规划确立的城镇体系布局,是建立市区、卫星城、中心镇和建制镇的四级城镇体系。本对北京卫星城发展中存在的问题进行了分析,并提出加快发展卫星城的政策。  相似文献

Over the course of the last decade, the equipment used by news organizations to transmit text, voice, and images from locations without fixed or operational communications links has changed radically. Whereas remote real-time transmissions once required tons of satellite uplink equipment, generators, and a stable of technicians, approximately the same can be accomplished today with a laptop sized device and handheld digital camera. This sort of technological prowess was seen most recently in the 2003 war in Iraq. We hypothesize that, as a result of these technological developments, the likelihood of newsgathering from remote locations has increased. By “remote location,” we mean any place without the standard technical infrastructure (fixed satellite uplinks or high-speed terrestrial lines). Most often, remoteness of this sort is a feature of nonurban, less developed regions of the world. This hypothesis is a critical but untested presumption underlying recent debates concerning the CNN effect, event-driven news, and other aspects of the changing nature of the relationships between news media and policy. In our analysis, we find evidence of a decrease in the effects of remoteness on levels of U.S. media coverage of distant events.  相似文献

In this paper we examine the actual legal situation concerning the attribution of geostatic positions and frequencies and the problems of frequency interference by other satellites due to not fully clear property rights. We analyze the property rights setting governing satellite communications and review the implications of the Coase theorem of these rules through a game theoretical approach between two players: Russia and Greece (Hellasat commercial communication attempt). The basic finding, in accordance with the theorem's prediction under non-zero and possibly high transaction costs, is that the end result may be sub-optimal due to the inappropriate present specification of property rights, leading either to non-use of scarce resources, or to total over-investment.  相似文献

In contrast to the increased popularity of gay and lesbian representations in the visual media of the early 2000s, the imagery of androgynous, inter-sex and transgender subjectivities, particularly in television commercials, is conspicuously limited. This article distinguishes three main categories of cinematic (mis)representation of gender transgression: the opportunistic lipstick, the “authentic” lipstick, and the fabulous lipstick. It examines this classification through the analysis of a unique, self-promotional television commercial broadcast by Yes+, an Israeli digital television channel whose visual contents often transgress the limits of mainstream television. Although the discussed advert conforms to the commercial imperative to attract Israeli audiences by all means, it is much more polysemic than one might notice at first glance. This study problematizes the sensational aspects of this “spectacular drama,” embraces its diverse erotic identifications and re-examines the price of queer visibility in the age of exploitive striptease culture.  相似文献

随着机动车犯罪案件数量的增多,犯罪手段的智能化、技术化、集团化趋势日益明显,公安机关的传统侦控方式已经不能满足遏制这类犯罪的需要,而追踪机动车的行动轨迹成为侦查此类犯罪的常用程序,故建议在全国机动车上强制安装卫星定位系统,以此来控制机动车犯罪.立法机关应当把“机动车上强制安装卫星定位系统”的建议写入《中华人民共和国道路交通安全法》.这一技术手段的应用可能会触及公民的隐私权,但其社会的公益性远远大于个人的隐私权,而且公民的隐私权也能够得到有效的充分保护.  相似文献

目前我国公安移动通信存在大面积的盲区 ,给公安实际工作带来了很大的困难。要改变这种状况 ,只有建立我国公安卫星移动通信系统。为实现话音、定位通信 ,支持手持机 ,采用中轨卫星移动通信系统或低轨卫星移动通信系统最为合适。  相似文献
