空间碎片主动移除任务的相关法律问题

外层空间活动增多,空间环境日益恶劣,但却欠缺相应的国际国内空间法律。基于空间碎片主动移除任务流程,提出中国作为移除任务责任主体应遵循法律约束,他国作为行为主体造成中国卫星损害时可采取法律保护。初步构想中国空间碎片主动移除任务的法律机制,针对移除飞行器方案设计阶段和飞行试验阶段,分别制定风险评估、许可登记、监测预警、应急机制以及赔偿处罚制度。结合中国航天技术领域发展现状,提出应进一步完善中国空间碎片减缓标准及政策法律机制建设。     

关陇庙会空间设计初探1

关陇地区的庙会空间仍处于一个相对“原始”的状态,在整体上缺乏一个合理的规划和设计。从庙会的空间构成和设计思路上进行探析和研究,在保护和传承的前提下,使庙会的空间规划合理,给庙会的参与者提供一个优良的空间环境,其空间设计应以适度的规模、合理的选址、人性化的关怀、氛围的营造,彰显地域文化特色为追求理念。     

中国区域建筑业的产业关联空间差异性三维系统分析

从系统的角度,提出了“发展关联、竞争关联与协作关联”三维产业关联分析框架,为全面、系统地分析特定产业的发展状况提供了新思路,并将研究思路运用到中国建筑产业中,首先将中国31个省份划分为8个区域,然后分别测算8个区域建筑产业的发展关联、竞争关联与协作关联.研究发现:发展关联维度下,全国8大区域内建筑产业影响力系数均超过了1,建筑产业在各区域经济中发挥着重要作用;感应系数普遍较低,维持在0.6,处于偏低状态.竞争关联维度下,8大区域中,京津、东部沿海和南部沿海三区域建筑产业溢出效应明显;相比之下,东北地区与中部地区的建筑产业对其他区域整体经济拉动作用甚微.协作关联维度下,各区域施工与咨询行业均呈现出高度相关性,目前中国区域内的咨询与施工主要以区域内的业务为主.需要强调的是,东部沿海施工与咨询的相关性很差.     

城市游憩空间的政府管理机构整合方案探索

城市游憩空间关联于多个政府职能部门,因此只能获得破碎化的公共服务,导致大部分城市的游憩空间既不能很好地满足人的发展,也不能很好地满足旅游发展,整合分散在各部门的管理职能显得非常必要。为了探索整合方案,本文从价值取向（旅游发展取向与人的发展取向）、组织形式（集权－命令式与分权－协商式）展开分析,由此推导出四种可能的整合方案：一是相关职能划归旅游局,二是成立旅游局牵头的部际协商委员会,三是相关职能划归文化局,四是成立文化局牵头的部际协商委员会。各个城市政府可以根据自身的实际状况做出选择：闲暇旅游驱动型旅游城市可以选择第1种方案;商务旅游驱动型旅游城市可以选择第2种方案;非旅游型中小城市可以选择第3种方案;非旅游型大城市可以选择第4种方案。     

自然地理环境贫困效应实证分析——基于空间贫困理论视角

从空间贫困理论的视角,根据自然地理环境、社会经济发展水平与贫困发生之间的关系,构建面板数据模型,并运用2006-2012年新疆17个边境重点贫困县市的面板数据进行实证分析,探讨自然地理环境的贫困发生效应.回归分析结果表明,自然地理条件对农民收入和农村贫困率有显著影响,政府完善区域经济发展战略和相关政策,可以缓解自然地理环境对贫困效应的影响,农业经济的发展对农村贫困率的减低有显著性影响.     

作为仪式的布依戏研究

布依戏是布依族民族民间的特色戏剧,其存在不仅与布依族的民歌、舞蹈、民间文学及生产生活息息相关,而且也与布依族的民族民间信仰密切联系,因此可以说布依戏是多元文化的结晶。本文以“过渡仪式理论”分析布依戏神圣空间的构建,以及神圣空间与世俗空间的转换、沟通,从而实现布依戏的神性和世俗性的意义。在这样的过程中,布依戏不仅仅是戏剧艺术,在一定程度上成为了布依族精神文化的载体,并且在布依戏中通过一系列的仪式构建的神圣空间来传递布依族文化的精神内涵。所以布依戏是一个娱人娱神的戏剧,这也是它有别于传统中国戏剧的重要表现。     

The reinvention of the Promised Land: utopian space and time in Soviet Jewish exodus literature

The Jewish underground movement in the Soviet Union in the second half of the 1960s produced literature that became a part of the counterculture of Soviet dissent. For the first time in decades, Russian Jews identified, to a significant degree, as people of the galut (Jewish Diaspora). The battle for the return to Israel and the new Jewish renaissance in the intellectual sphere of the unofficial led to the emergence of new topographical concepts, which were inspired primarily by the Jewish cultural tradition. In fact, the exodus texts written in the 1960s–1980s represented a new, late Soviet shaping of Zionist prose. They relate to the symbol of the Promised Land as a fundamental projection of aspirations. Late Soviet Zionist texts share the traditional Jewish vision of Israel as an imagined topos of the original homeland that is both retrospective (with reference to the biblical promise of the land and the seizure of Canaan) and prospective (return and redemption). The Exodus story contained in Sefer Shemot becomes a leading poetic, philosophical and at times religiously charged metaphor of liberation and reunification. The re-strengthened collective memory of tradition required biblical symbols to be imbued with new semiotic power.

This paper will show that the historical dimension of the events dealt with in the literature often has strong mystical and mythological traits and displays messianic-apocalyptic hopes of salvation. However, alternative literary space and time models represented in the aliyah literature hereby betray their rootedness in the teleology of the communist regime. The powerful Israel utopia reflects both the eschatological time of the Soviet empire and its phantasms of paradise on earth. Late Soviet Zionism and totalitarian discourse are shown to be two space-time utopias.

Maximizing Probability Bounds Under Moment-Matching Restrictions

The problem of characterizing a distribution by its moments dates to work by Chebyshev in the mid-nineteenth century. There are clear (and close) connections with characteristic functions, moment spaces, quadrature, and other very classical mathematical pursuits. Lindsay and Basak posed the specific question of how far from normality could a distribution be if it matches k normal moments. They provided a bound on the maximal difference in cdfs, and implied that these bounds were attained. It will be shown here that in fact the bound is not attained if the number of even moments matched is odd. An explicit solution is developed as a symmetric distribution with a finite number of mass points when the number of even moments matched is even, and this bound for the even case is shown to hold as an explicit limit for the subsequent odd case. As Lindsay noted, the discrepancies can be sizable even for a moderate number of matched moments. Some comments on implications are proffered.     

The Inherent Politics of Managing the Quality of Urban Green Spaces

Although the term ‘quality’ has a universal positive connotation and typically is framed by a focus on improvements, its application includes as well as excludes the access, values and world views of particular actors and interests. In this article, we highlight the relevance and implications of such ‘inherent politics’ through a case study of a widespread approach to operationalizing quality in urban green space management. We conclude that adoption of any quality model has both limiting and enabling implications for public participation and decision-making and that a critical stance is needed within both research and practice for the development of quality models that connect to values of broader societal relevance.
