脊波导宽频带电磁参数测试技术

针对高损耗介质材料电磁参数的宽频带测试问题,提出了利用脊波导进行测试的新方法,建立了电磁参数测试系统,并采用TRL技术进行了系统校准。该方法仅用3个波段的脊波导即可覆盖2.0～18.0GHz宽频带范围内的电磁参数测试,具有频带宽、体积小、测试精确度高等优点。     

大吴文化研究纵横谈

大吴文化是一种广义的地域文化 ,即从古到今 ,吴地人民所创造的一切文化的总汇。吴地地域的界定 ,有广义、狭义之分 ,广义的吴地地域的界定应以历史政区和吴语分布区为依据。从大吴文化视角出发 ,可将吴文化视为一种丰富的知识性的资源 ,人们可纵横结合 ,从人类社会的多个层面予以研究、开发和利用。在长期的发展中 ,吴文化形成了先吴文化、吴国文化、吴地文化三个时期。吴文化具有自己的鲜明特色 ,其中主要有依托水 ;融合古今 ,汇通中西 ;后来居上 ,敢为天下先等     

西方现代性源起的中国灵感

中国形象曾经作为西方现代文化乌托邦精神的象征,参与构筑西方现代性经验.中国形象进入西方现代文化,先后出现了"大汗的大陆"、"大中华帝国"、"孔夫子的中国"三种形象类型,经历了器物、制度、思想三个阶段.马可·波罗时代强调的是物质上富强的中国形象,门多萨时代强调的是制度上完善的中国形象,伏尔泰时代强调的则是一个思想上具有深刻启蒙意义的中国形象.在西方现代性经验中纵深研究中国形象,提出了一个重要的问题,现代性是一个跨文化空间生成的概念,正如中国现代性离不开西方的启蒙,西方现代性中也有中国灵感.     

Pluralism and Universality of Environmental Discourse: The Dilemma Between Damage Caused by the Japanese Macaque and its Protection

Abstract:  The subject of this paper is to describe the complexity of relations between man and wild monkeys, which causes difficulties in forming a social consensus related to their conservation and management. To present how the relations are in everyday life, and how they are simplified in universal discursive spaces, interviews and a questionnaire survey have been conducted. As a result, it is clarified that there are three kinds of discursive spaces, that of politics, natural science, and residents. People who share the land with wild monkeys have various terms and stories about their relations with monkeys. The monkeys have various values in the discourse of residents, including many troubles. The existence of monkeys is vivid and close, and can be described as "accessible" nature. However, in discussion of politics or natural sciences, there is less diversity in monkeys' values. In these discursive spaces, monkeys are described simply in the framework of "distant" nature, and wild monkey issues are constructed as a "pest animal issue". The simplified protocol between accessible and distant nature makes the wild monkey issues simple. And the attitudes of residents are shown as controversial through the contradiction between simple-complex issues. In conclusion, this contradiction cannot be solved only by filling the gap between accessible and distant nature with social consensus, but also by connecting the two and enhancing the dynamism of society as a whole.     

Small‐sphere distributions for directional data with application to medical imaging

We propose novel parametric concentric multi‐unimodal small‐subsphere families of densities for p ? 1 ≥ 2‐dimensional spherical data. Their parameters describe a common axis for K small hypersubspheres, an array of K directional modes, one mode for each subsphere, and K pairs of concentrations parameters, each pair governing horizontal (within the subsphere) and vertical (orthogonal to the subsphere) concentrations. We introduce two kinds of distributions. In its one‐subsphere version, the first kind coincides with a special case of the Fisher–Bingham distribution, and the second kind is a novel adaption that models independent horizontal and vertical variations. In its multisubsphere version, the second kind allows for a correlation of horizontal variation over different subspheres. In medical imaging, the situation of p ? 1 = 2 occurs precisely in modeling the variation of a skeletally represented organ shape due to rotation, twisting, and bending. For both kinds, we provide new computationally feasible algorithms for simulation and estimation and propose several tests. To the best knowledge of the authors, our proposed models are the first to treat the variation of directional data along several concentric small hypersubspheres, concentrated near modes on each subsphere, let alone horizontal dependence. Using several simulations, we show that our methods are more powerful than a recent nonparametric method and ad hoc methods. Using data from medical imaging, we demonstrate the advantage of our method and infer on the dominating axis of rotation of the human knee joint at different walking phases.

A transnational networked public sphere of air pollution: analysis of a Twitter network of PM2.5 from the risk society perspective

ABSTRACT

Drawing on digitaltrace data, publicly accessible government documents, and journalistic reports, this research integrates Beck’s risk society theory with digital media theories to examine the mediated process of risk definition and assessment of PM2.5 (particulate matters with a diameter less than 2.5 micrometers) in a networked public sphere. Network and content analysis of a PM2.5 Twitter network shows that political and professional elite remained the most powerful producers of risk definition. Established media played a key role, yet faced challenges from a variety of actors who disseminated and filtered information. Laypersons, while peripheral, actively interacted with elite and established media. The blurring geographic boundary in the PM2.5 Twitter network revealed an emerging transnational public sphere, which, however, was segregated by language. This research advances a layered understanding of the contingent, paradoxical media impact for social changes in a risk society.     

超越自在:论阿伦特的自由观

阿伦特的自由观是阿伦特政治思想的重要组成部分,其最重要特色或许就是对政治自由的强调。在阿伦特看来,自由并非是人天然存在的某种本质,而是、也只能是政治自由,离开政治以及政治实践得以展开的公共空间,自由就不可能存在,而离开自由的政治也不是真正的政治。从生活必需品和物质必然性的束缚中解脱出来的过程只是解放,而非自由。自由作为政治概念不仅不能停留在物质解放的层次,而且必须以实践的方式进入公共空间;也就是说,自由只存在于行动和言说领域,而不存在于思想王国或哲学王国,所谓主观自由、内在自由等等,都不是真正的自由。自由也并不意味着安全、舒适、富足,恰恰相反,它需要付出勇气、代价,收获的则是尊严和光荣。     

中国化“资产者公共领域”:从民间商会到市民社会的路径选择

学界对于“市民社会”与“公共领域”之概念工具存在理解歧义与混用,“市民社会”与“公共领域”两者均超越了中国化国家与社会之间互动关系的特殊国情,“资产者公共领域”可能是更实际的学理研究路径。在国家与社会互动关系的领域中间,是一个广泛、深邃的市民社会转型地带,并呈递进式状态,朝着市民社会的终极方向演进。当代中国的国家与社会之间互动关系的学理研究角度应是民间商会基础上的“资产者公共领域”,而非公共领域甚至市民社会。     

"有无"与"虚静"合一——从《老子衍》看王夫之对老子"有无"思维的研究

老子以"有无"境界,对人生实有领域的观照与觉悟,就是"虚静","有无"与"虚静"合一就是老子以境界形态的"有无"思维论证人生领域"无中之有"的"虚静"与"无"之境界的合一,这体现了老子境界形态"有无"思维的特征。王夫之以万物实有为思维起点,以实有形态的"有无",即:"有"与"有中之无"论"虚静",统一"有无"与"虚静"于"有"与"无中之有"的实有境界之中,从而从哲学思维的深度论证了"有无"与"虚静"合一于实有,即"有无"与"虚静"统一于"有"与"有中之无"合一的万物实有。
