科幻小说科学传播影响力提升的AMO 分析

随着互联网、手机的普及,搜索引擎以及基于搜索的互动式知识问答分享平台等自媒体应用,人们获取科学信息的能力与速度有了大幅提高。传统强调科学信息传播的“科学普及”,逐渐被强调从受众出发的“科学传播”所替代,后者更加注重传播过程的趣味性、情节性和传播效果的影响力。科幻小说在传播科学思想、科学观念、科学精神以及科学方法与知识方面,尤其符合自媒体时代的传播特征,显现出其他通俗科普读物难以匹及的科普功效。本文从传播学的角度出发,拟借助说服传播的精细加工可能性模型（ELM）,将其中的AMO （能力、动机、机会）三因素作为分析视角,对科幻小说科学传播影响力的提升提出了分众化、娱乐化、多媒体化的传播策略。     

屠呦呦获诺贝尔奖事件的跨媒介传播分析

本研究以屠呦呦获得诺贝尔奖为例,试图了解科学事件在不同的媒介平台,传统媒体与社会化媒体上传播的情 况。运用内容分析的方法,分析传统媒体、社会化媒体的新闻报道。研究发现,社会化媒体对此类科学事件的关注度 较高,较传统媒体有更强的时效性,但热点话题消退也非常快。而两者所关注此次事件的议题也大相径庭,传统媒体 更偏向祝贺赞扬类及向公众传播科学知识,社会化媒体平台则更加倾向于科学传播中“人”的参与及争议性的话题, 同时,社会化媒体上的科学传播文本也呈现了优质、深度的内容,并影响了传统媒体的议题,其在科学传播上的作用 也不容忽视。

网络“大V”的管理

随着现代信息技术的快速发展,一些新兴媒体也不断地崛起,如微博、微信等一些社交网站,随之有很多网络“大V”脱颖而出.他们大多都是拥有很多数量的“粉丝”,且这些网络“大V”能够凭借自己的网络号召力、影响力,已经成为现代媒体传播中不可忽视的中坚力量.如何更好地利用网络“大V”传播积极的影响,就需要进行科学的管理.本文认为需要以主流媒体为主,对网络“大V”加以正确引导的同时,也要净化网络环境,并且加大对民生的关注力度.     

科学博客：探索在公众理解科学的最前沿

近几年,随着博客技术的发展和日臻成熟,科学博客浮出水面,逐渐形成了一股蓬勃发展的在线科学群体力量,在科学公共领域发挥着一定的影响。一方面,科学博客的出现改变了传统的科学传播方式,使科学家进入科学传播的媒介系统,成为科学传播的主体,显示了＂自媒体＂越来越大的传播潜力。另一方面,它以其开放性、互动性、高效性,成为科学传播的一个便捷、高效的载体,为公众提供了一个新的获得科学知识和科技信息的渠道,继而影响着公众对科学的理解和对科学技术态度。尽管科学博客想取代大众传播媒介还为时过早,但科学博客与专业媒体的汇流趋势已经在科学传播的变革中逐渐凸现。本文将从科学博客的现状、传播手段、传播主体、传播内容、未来发展趋势等几方面研究科学博客在现代传播体系中的特色,探讨科学博客在促进公众理解科学中发挥的作用和潜在影响。     

读图时代的科学传播现状及策略

“读图时代”对科学传播提出了新的课题,图像不再是文字的附属和、点缀,开始担负起传递信息、传播观点的职能。摄影在中国有着广泛的群众基础,技术的进步又大大提高了图像的传播效果,报刊、图书等各种科普出版物“浓眉（题）大眼（图）”,电影、电视、动画等更是让人们享受,到了视觉的盛宴。与此同时,泛视觉化倾向却削弱了受众清醒认识世界的能力≯在这个视觉时代有必要分析图像的传播特征,研究一影像的传播策略,探索视觉时代的科学传播之路。”     

“诊脉验孕”挑战赛的传统媒体框架建构 ———基于报纸新闻的“解释包”分析

微博上发起的“诊脉验孕”挑战赛是中国医疗界近年来重要新媒体事件之一,其背景涉及中医之争。本文使 用Gamson 等人的框架理论的“解释包”分析方法,研究该事件发生过程中传统媒体上的294 篇报道,分析媒体对 “诊脉验孕”挑战赛的框架建构类别、过程和特点。研究结果发现传统媒体主要受到现有医疗体制和社会文化影响而 普遍采用支持中医的框架,说明中医一方和政府行政管理部门掌握了传统媒体的话语权。由于科学诠释框架较少被传 统媒体用来建构中西医之争新闻,因此需要深入探讨在传统媒体上如何进行科学传播。

Curved crystal spectrometer for the measurement of X-ray lines from laser-produced plasmas

In order to diagnose the laser-produced plasmas, a focusing curved crystal spectrometer has been developed for measuring the X-ray lines radiated from a laser-produced plasmas. The design is based on the fact that the ray emitted from a source located at one focus of an ellipse will converge on the other focus by the reflection of the elliptical surface. The focal length and the eccentricity of the ellipse are 1350 mm and 0.9586, respectively. The spectrometer can be used to measure the X- ray lines in the wavelength range of 0.2-0.37 nm, and a LiF crystal （200） （2d = 0.4027 nm） is used as dispersive element covering Bragg angle from 30° to 67.5°. The spectrometer was tested on Shengnang- Ⅱ which can deliver laser energy of 60-80 J/pulse and the laser wavelength is 0.35 μm. Photographs of spectra including the 1 s2p ^1P1-1s^2 ^1S0 resonance line（w）, the 1s2p ^3P2-1s^2 1S0 magnetic quadrupole line（x）, the 1s2p ^3P1-1 s^2 ^1S0 intercombination lines（y）, the 1 s2p ^3S~1-1 s^2 ^1S0 forbidden line（z） in helium-like Ti Ⅹ Ⅺ and the 1 s2s2p ^2P3/2-1 s622s ^2S1/2 line（q） in lithium-like Ti Ⅹ Ⅹhave been recorded with a X-ray CCD camera. The experimental result shows that the wavelength resolution（λ/△ 2） is above 1000 and the elliptical crystal spectrometer is suitable for X-ray spectroscopy.     

Preparation and Characterization of TaN ALD Precursors

High purity organic-tantalum precursors for thin film ALD TaN were synthesized and characterized.Vapor pressure and thermal stability of these precursors were studied.From the vapor pressure analysis,it was found that TBTEMT has a higher vapor pressure than any other published liquid TaN precursor,including TBTDET,TAITMATA,and IPTDET.Thermal stability of the alkyl groups on the precursors was investigated using a 1H NMR technique.The results indicated that the tertbutylimino group is the most stable group on TBTDET and TBTEMT as compared to the dialkylamido groups.Thermal stability of TaN precursors decreased in the following order:TBTDET ＞ PDMAT ＞ TBTEMT.In conclusion,precursor vapor pressure and thermal stability were tuned by making slight variations in the ligand sphere around the metal center.     

A Versatile Mixed-Signal Pin Approach for Cost-Effective Test of Automotive ICs

Integrated circuits (ICs) intended for increasingly sophisticated automotive applications bring unique test demands. Advanced ICs for applications such as highly integrated automatic braking system (ABS) and airbag controllers combine high voltage digital channels, significant VI demands and precise timing capability. Along with continued missioncritical reliability concerns, the trend toward higher voltage operation and increased device integration requires specialized test capabilities able to extend across the wide operating ranges found in automotive applications. Among these capabilities, automotive test requirements increasingly dictate a need for a cost-effective versatile mixed-signal pin electronics with very high data rates reaching up to 50MHz with a voltage swing of-2 V to +28 V.     

Electronic Structure of Semiconductor Nanocrystals

This paper reviews our recent development of the use of the large-scale pseudopotential method to calculate the electronic structure of semiconductor nanocrystals, such as quantum dots and wires, which often contain tens of thousands of atoms. The calculated size-dependent exciton energies and absorption spectra of quantum dots and wires are in good agreement with experiments. We show that the electronic structure of a nanocrystal can be tuned not only by its size,but also by its shape. Finally,we show that defect properties in quantum dots can be significantly different from those in bulk semiconductors.
