新世界主义视野下的中国传媒发展

编辑之友 2017年第1期 5-12页

作者：邵培仁王昀浙江大学传媒与国际文化学院浙江杭州310028

近年来,中国关于"世界"的论述,体现出一种新世界主义视野。特别是"一带一路"作为当前国家主导叙事,不仅激活了新的媒介地理想象,并且正演变为颇具代表性的世界主义话语,预示中国国际传播顶层决策正在不断调试、探索新的路径和面向。因此... 详细信息

近年来,中国关于"世界"的论述,体现出一种新世界主义视野。特别是"一带一路"作为当前国家主导叙事,不仅激活了新的媒介地理想象,并且正演变为颇具代表性的世界主义话语,预示中国国际传播顶层决策正在不断调试、探索新的路径和面向。因此,传媒在呈现"一带一路"的角色表达时,必须关注其中涵盖的多重机理以适应国家抉择:"一带一路"既牵涉历史性的共同体叙事,又是本土性框架过滤的产物;其以现代化观念作为全球共识策略,亦透过地缘化布局展开治理机制。"一带一路"自身作为复杂的世界主义想象的被接受过程,也将内在驯化中国传媒产制,使之丰富本土的世界认知,推动制度优化与经验对话,重新反思全球化、区域化中的信息资源分配网络以及文化地理认同路径,从而进一步考量中国国际传播的未来空间。

本文在研究我国能源消费的过程中,通过对经济学理论和以往学者研究成果的总结分析,得出了经济发展、经济结构、城镇化率、研究与实验发展经费支出等四因素直接影响能源消费的结论。文章利用2003-2008年六年间国内30个省(区、市)的相关数据构建了四个因素对能源消费影响的固定效应面板数据模型,有效地分析了不同要素对能源消费的影响程度。同时,利用自回归移动平均模型对我国2010年的能源消费进行了预测。本文认为,在今后一段时期内,我国的能源消费量将持续增长。加大科技投入和科技创新,提升产业技术水平,提高能源的利用效率,是强化我国在能源领域的竞争力,促进中国经济可持续发展的有效路径。

Objective: To understand whether arsenic trioxide (As2O3 )-induced biological effects are associated with degradation of PML proteins. Methods Acute promyelocytic leukemia (APL) cell line NB4, acute T-lymphocytic leukemia cell line Jurkat, acute myeloid leukemia cell line U937, and chronic myelocytic leukemia blast crisis cell line K562 were used as in vitro models In different cell lines, the As2O3-induced biological effects were determined by cell growth, cell viability, cell morphology, and flow cytometry assay on sub G1 cell content. The alteration of PML proteins was analyzed by immunofluorescence Results in terms of growth inhibition and apoptosis induction, 1. 0μmol/L As2O3 had different effects on different cell lines. However, degradation of PML proteins occurred in all the cell lines with As2O3 treatment. Conclusion As2O3-indued biological effects may be independent of PML protein-degradation.

Global Positioning System(GPS) trajectory data can be used to infer transportation modes at certain times and locations. Such data have important applications in many transportation research fields, for instance,to detect the movement mode of travelers, calculate traffic flow in an area, and predict the traffic flow at a certain time in the future. In this paper, we propose a novel method to infer transportation modes from GPS trajectory data and Geographic Information System(GIS) information. This method is based on feature extraction and machine learning classification algorithms. While using GIS information to improve inference accuracy, we ensure that the algorithm is simple and easy to use on mobile devices. Applied to GeoLife GPS trajectory dataset, our method achieves 91.1% accuracy while inferring transportation modes, such as walking, bike, bus, car, and subway, with random forest classification algorithm. GIS features in our method improved the overall accuracy by 2.5% while raising the recall of the bus and subway transportation mode categories by 3.4% and 18.5%. We believe that many algorithms used in detecting the transportation modes from GPS trajectory data that do not utilize GIS information can improve their inference accuracy by using our GIS features, with a slight increase in the consumption of data storage and computing resources.

To investigate the performance of graphene(Gra) modified with ethoxycarbonyl ionic liquid(IL), chain mobility and crystallization kinetics of poly(L-lactic acid)(PLLA), a series of PLLA nanocomposites have been prepared using solution-cast *** can improve the dispersion of Gra in PLLA matrix and the samples containing IL have higher growth rate of PLLA spherulite than neat PLLA does. PLLA/IL/Gra and PLLA/2 Gra exhibit the same relaxation strength and time of αN relaxation that corresponds to the longest normal mode motion at 110-140 °C. PLLA/IL/Gra shows a faster crystallization rate than PLLA/2 Gra does, which might be attributed to the Gra-imidazolium cation interaction in IL modified Gra, the significant dispersion effect of IL at Gra surface, and the increase of nuclei density of PLLA/IL/Gra.
