我国偶像性体育明星社会影响力探析

运用文献资料等方法对以孙杨、林丹、李娜、姚明、刘翔、丁俊晖等为代表的偶像性体育明星的社会影响力进行分析。他们的社会影响力表现在其对社会正确价值观的树立与引领,对优秀传统文化的承载与传播,对中国崭新形象的展示与国际交流融通,对社会经济发展的助推与促进,对体育项目的普及推广与升华,对时尚潮流的革新与突破等方面。今后提升偶像性体育明星社会影响力的对策包括:培育偶像性体育明星的品牌意识,对其进行整体设计打造;延长偶像性体育明星效应,促使其影响力最大化;借鉴演艺界推广经验,加大宣传力度等。

偶像梦露在床上

从前，我有一个同事．在某天的早晨．气急败坏“我的电脑我的电脑．不知道是谁干的，一开IE．就是色情网站．还怎么设首页都设不回去，谁帮我搞掂这事啊，我请吃饭。”

Folate-conjugated Fe_3O_4 nanoparticles for in vivo tumor labeling

Highly biocompatible superparamagnetic Fe3O4 nanoparticles were synthesized by amide of folic acid （FA） ligands and the NH2-group onto the surface of Fe3O4 nanoparticles. The as-synthesized folate-conjugated Fe3O4 nanoparticles were characterized by X-ray diffraction diffractometer, transmission electron microscope, FT-IR spectrometer, vibrating sample magnetometer, and dynamic light scattering instrument. The in vivo labeling effect of folate-conjugated Fe3O4 nanoparticles on the hepatoma cells was investigated in tumor-bearing rat. The results demonstrate that the as-prepared nanoparticles have cubic structure of Fe3O4 with a particle size of about 8 nm and hydrated diameter of 25.7 nm at a saturation magnetization of 51 A·m2/kg. These nanoparticles possess good physiological stability, low cytotoxicity on human skin fibroblasts and negligible effect on Wistar rats at the concentration as high as 3 mg/kg body mass. The folate-conjugated Fe3O4 nanoparticles could be effectively mediated into the human hepatoma Bel 7402 cells through the binding of folate and folic acid receptor, enhancing the signal contrast of tumor tissue and surrounding normal tissue in MRI imaging. It is in favor of the tumor cells labeling, tracing, magnetic resonance imaging （MRI） target detection and magnetic hyperthermia.

全球化与全球治理

全球化及其相关问题是人类发展史上的一个现代现象,它是各个国家、地区与民族寻求自身发展的一个过程,是世界政治、经济制度、知识理念、个体与群体心理结构以及文化制度集合而发生的一次深刻的、全方位的秩序转变的过程。现代性全球化所特有的矛盾、流动与风险,引发了对其反偶像性的思考,全球治理模式的认知与建立是本世纪人类生存和发展的重大课题。
