南阳和襄樊两地旅游发展的矛盾及对策探讨

南阳和襄樊都有着比较丰富的旅游资源,但两地在旅游业发展上存在着巨大的矛盾,严重制约着两地旅游整体效益的发挥.在分析两地旅游业发展的现状以及存在的矛盾基础上,论述了两地之间的合作优势,提出两地应该转变观念、进行合作,共塑"诸葛亮躬耕地"这一旅游地品牌形象等措施.     

规划理论和实践中的空间观念辨析

规划理论和实践中的空间观念塑造着我们周围的人造环境。空间观念的发展呈现出从绝对到相对、从时空分离转向时空关联、从一元到多元的变化趋势。20世纪以来规划理论逐渐吸纳相对空间观念,但迄今为止规划实践仍以绝对空间观念为主导。绝对空间观念成为规划实践低效性的深层原因,但是完全放弃绝对空间观念而将相对空间观念引入规划理论和实践不仅存在很多困难,而且会造成认识和实践上的混乱,科学的空间观念应该将绝对和相对结合起来形成多元空间观。我国规划理论研究和实践仍以绝对空间观念为主导,了解绝对空间观念的不足和吸纳相对空间观念的合理性具有重要的理论和实践意义。     

从知名企业的实践看内部控制在我国的应用

内部控制是企业加强经营管理的基本方式,它体现着现代企业经营管理的需求,有利于加强企业经营管理,达到公司治理、追求最大化利润的目的.联想和海尔两大集团的实践经历,是现代企业内部控制的应用方法以及操作模式的典范,为现代企业高级管理层以及财务总监提供了有益借鉴.     

城市建筑空地遗留与区位建设——以北京市为例

现代城市问题,归根到底是人与地的关系问题,疏浚和控制人口密度是当前城市发展所不容忽视的重要课题.通过实地考察和对北京市区位建设相关数据的理论分析,认为在旧城改造和新城建设中,为有效控制人口聚集的密度,当前应主要致力于:一是重视建筑高度和密度的控制,为其设定具有法律效力的底线标准;二是在遵循市场运行规律的前提下,合理划分城市区位,引导进行多核心的数量、品位、质量、规模大致相同的功能分布体的区位建设.     

加权Hardy空间的不变子空间

证明了加权Hardy空间H^2（β）的乘子代数M（H^2（β）（当H^2（β）的权序列满足^∞∑n=1 1/β（n）^2〈＋∞时）的不变子空间M在单位圆盘内有有限个公共零点时的结构．在这种情况下,M由其公共零点表示成：M=（z—z1）…（z—zn）M（H^2（β））．     

黎曼浸没在全空间中的特征值估计

给出了一类黎曼浸没在全空间中第一特征值的下界估计．设π：M→N为黎曼浸没,其中M是个非紧致流形,N是个在无穷远点有一个极点的黎曼流形,而且Ric（M）≤-（n--1）k,这里k〉0,如果｜｜H｜｜≤c≤（n-1）,那么,λ1（M）≥{（n-1）k-c}^2/4,从而得到了著名的Mckean定理。     

Roadmap for interactive exploration of sustainable development opportunities: The use of simple instruments in the complex setting of bottom-up processes in rural areas

Before embarking on the development of rural areas or regions it seems necessary to answer the following key questions: what goals of the parties involved can be realized, and where, when and how? To tackle these questions we have developed a ‘roadmap’, as part of an overall sustainable development procedure for physical planning and spatial management in rural areas. The roadmap is a tool for the process manager and the people involved. It helps to find the way in the exploration of the potential social, economic and ecological benefits of developing the area or region. The purpose of using the roadmap is to alleviate doubts about the advantages of cooperating in pursuit of sustainable development. A back-casting approach is applied to create appealing visions of the future and visualize mutual opportunities worth implementing. In this article we first describe the need for this new roadmap. We then describe its use, step by step and in some detail. An example of the exploration process is described and the strengths and weaknesses of the roadmap are discussed.     

土壤污染防治法背景下的城乡绿地系统建设：趋势与对策

《中华人民共和国土壤污染防治法》的颁布标志着中国将形成完善的土壤污染防治法律体系,建立从污染土壤调查、修复、风险防控、监测到场地再利用,从环境标准到规划管理的全方位制度。生态文明制度建设的宏观背景,再加上中国土壤污染严重、规模大、修复难、成本高、周期长等特征,将导致大量污染场地转变为绿地或生态用地,最终对绿地系统的数量与规模、布局与功能、规划与管理、环境质量标准等多个维度产生实质性影响。分析这一趋势,对其影响提出预判,最终提出对策建议。     

汇水系统绿地雨洪调蓄研究——以武汉港西汇水系统为例

绿地有一定的雨洪调蓄功能,雨洪状况下,如何在汇水系统尺度利用和保护绿地亟待研究。选取95处位于武汉港西汇水系统的地块,调研地块性质,利用ArcGIS提取不透水比例及平均坡度,并进行SWMM水文模型演算。通过实验性模拟结果的对比,得出汇水系统的绿地雨洪调蓄效率(λ＝0.13m3/m2)、汇水系统(g＝36%)和各类用地(g＝18%～47%)基于雨水调蓄理念下的最低绿地率,使汇水系统水文状况达到海绵城市建设标准。讨论了不同重现期下汇水系统的绿地雨洪调蓄效能,旨在完善绿地雨洪调蓄的研究方法、指标体系及利用与保护策略,为相关研究与实践提供借鉴。     

Knowing your place and commanding space: de/constructions of gendered embodiment in mixed-sex karate

ABSTRACT

Feminists have long acknowledged that gendered divisions in access to spaces of leisure, and how women and men physically take up that space, reproduce gender inequality. This article will explore how karate practitioners participate in the space of mixed-sex karate practice and how such uses of space de/construct gendered embodiments and a gender hierarchy. Data presented are drawn from nine months of ethnographic emersion within three karate clubs and 15 photo-elicitation interviews with karate participants from the three clubs. The findings of this paper suggest that whilst women often occupied spaces of expertise within the karate hall, gendered distinctions in uses of space emerged in the more subtle ways in which women and men used their voice, responded to the tacit and smelt dilemmas of sweat, and moved their bodies across physical space. This research highlights both the potential of physical leisure practice to ‘undo’ conventional gendered embodiments that particularly restrict women’s intentionality in the world, and the power of spatially attuned research to illuminate the minute ways in which unequal gender relations are naturalised, legitimised and done.
