“社区”的维度与限度

当今"社区"("共同体")概念在我国长驱直入,大有替代我国传统的诸如村庄、乡社、邻里、街坊、城邑之趋势。任何一种人群"共同体"单位形制,都是经历长时段形成的,并被赋予特定、特别的内涵。厘清这些"共同体"的内涵和外延,对中国乡土社会的认识大有裨益。"社区"是一个近代舶来概念,有其维度与限度,不可完全替代和超越我国传统的概念。国家社会科学基金(艺术类)重点项目“中国特色艺术学体系研究”阶段性成果(17AA001

家在“念”中:国家级非物质文化遗产《亚鲁王》的认知与阐释

非物质文化遗产是人类主体认知、实践与社会情境的综合性显现。运用人类学的认识论和方法论,探究族群文化的原初逻辑与完整价值具有合理性。在此基础上可提出对该遗产认知与阐释的新向度:“亚鲁“1不仅是麻山苗人在史、诗、歌中对“英雄祖先“的记忆与纪念,也是他们以本朴的“情“和“理“,编织而成的“家园感“。家在“念“中,既是族群的生存策略和生活方式,亦是“亚鲁“作为非物质文化遗产的价值核心和传承之道。2011年度国家社科基金重大项目“中国非物质文化遗产体系探索研究”(批准号:11&ZD123

从“文学人类学”到“旅游人类学”——厦门大学彭兆荣教授访谈

彭兆荣教授结合自己在西南民族地区的生活经历,回顾了由外国文学到古希腊文化酒神精神与文学仪式的研究转向,这种转向主要缘于西方知识考古学思潮的影响,尝试通过西方文化的知识考古以探究文学中所谓诗学的源头。访谈还涉及以下重要论题:首先,如何正确认识中国语境下比较文学与文学人类学的特定关联;其次,文学人类学的跨学科交叉视角对于当下文学批评的现实意义;再次,如何认识民族志的"真实性",如何重估"大传统"与"小传统";最后,彭教授结合中国具体的社会历史语境,从民族仪式、家园意识与民族认同角度评价了旅游人类学或非物质文化遗产研究中涉及的国家政治认同与民族文化认同间的关联,并大力倡导建立一种具有中国特色的非物质文化遗产体系

Rational Design and Fabrication of ZnO Nanotubes from Nanowire Templates in a Microwave Plasma System

Xiamen Univ, Dept Chem, State Key Lab Phys Chem Solid Surfaces, Xiamen 361005, Peoples R ChinaA nanowire-nanocable-nanotube scheme was designed for fabricating tubular ZnO in a microwave plasma system. Depending on optimal reaction conditions, diameters (from submicrometer to nanometer) and wall thicknesses of the tubular ZnOs can be controlled in the process. Data from morphology analyses, X-ray diffraction, photoluminescence spectra and Raman spectroscopy of the as-prepared ZnO nanotubes support the validity of the proposed three-step route for the fabrication of tubular ZnO

High purity trigonal selenium nanorods growth via laser ablation under controlled temperature

Xiamen Univ, Dept Chem, State Key Lab Phys Chem Solid Surfaces, Xiamen 361005, Peoples R ChinaBy utilizing laser ablation, high purity trigonal selenium nanorods with different size have been synthesized from selenium powders. The high purity of the nanorods is attributed to freestanding growth process without catalyst or template. Its morphologies depend on both substrate temperature and reaction time. By controlling the experimental conditions, selenium nanorods with lateral dimensions in different range can be synthesized ranging from 20 nm to several hundred nanometers in width, and up to 10 mum in lengths.

Low temperature solvothermal synthesis of crumpled carbon nanosheets

通讯作者地址: Xie, ZX (通讯作者), Xiamen Univ, Dept Chem, State Key Lab Phys Chem Solid Surfaces, Siming Nanlu 422, Xiamen 361005, Peoples R China 地址: 1. Xiamen Univ, Dept Chem, State Key Lab Phys Chem Solid Surfaces, Xiamen 361005, Peoples R China 电子邮件地址: [email protected] carbon nanosheets have been successfully synthesized via a catalyst-free solvothermal route at very low temperatures (60-100 degreesC), using tetrachloromethane as the carbon source and potassium as the reductant. The X-ray powder diffraction pattern indicates that the products are hexagonal graphite. Transmission and scanning electron microscopy show that the thickness of crumpled carbon nanosheets ranges from 3 to 8 nm. Raman spectroscopy supports the existence of graphitized carbon at the nanoscale. BET experiments show that carbon nanosheets have a large surface area. Compared with previous methods to prepare graphite nanosheets, such a low reaction temperature has attractive advantages

Growth of Prussian blue microcubes under a hydrothermal condition: Possible nonclassical crystallization by a mesoscale self-assembly

通讯作者地址: Xie, ZX (通讯作者), Xiamen Univ, Dept Chem, State Key Lab Phys Chem Solid Surfaces, Coll Chem & Chem Engn, Xiamen 361005, Peoples R China 地址: 1. Xiamen Univ, Dept Chem, State Key Lab Phys Chem Solid Surfaces, Coll Chem & Chem Engn, Xiamen 361005, Peoples R China 电子邮件地址: [email protected] classical crystallization process starts from stable nuclei followed by a simple enlargement of the nuclei by unit-cell replication. In recent years, the universality of such classical crystallization has been questioned upon investigations of biomineralization processes, and there are few examples showing that crystal growth may not follow such a classical crystallization process. In this paper, a typical coordination polymer, Prussian blue microcrystals, has been synthesized under hydrothermal conditions. By carefully analyzing the intermediates during the crystal growth process, we found that the growth of Prussian blue under the given growth conditions may follow a nonclassical crystal growth process in which a mesoscale self-assembly of nanocrystallites is included during crystal growth. Such a mesoscale self-assembly process could be a common phenomenon for growth of some crystals with extremely low solubility
