20世纪20年代《自然界》对“科学的中国化”的议程设置

文章综合运用文献研究法和数理统计法,对《自然界》1926至1931年全部6卷文章进行统计、分析和研究。发现《自然界》对"科学的中国化"的议程设置呈现出以下四个特点:通过文章数量来凸显核心议题;在传播内容上加强"中国化"特征;表现形式丰富多样增强议题吸引力;专业的编撰队伍保证了文章的严谨性。《自然界》在对"科学的中国化"的议程设置中充分发挥了舆论引导作用,推动了当时西方科学在中国的本土化进程,为后来声势浩大的"科学化运动"奠定了理论和实践基础。

新闻播报的“播”与“说”

随着社会多元化发展,为了增强新闻传播的效果,很多新闻节目纷纷开始了新闻播报方式的创新和改革,其中最主要、影响较大的两种就是以《新闻联播》为代表的"播新闻"和以《凤凰早班车》为代表的"说新闻"。"播"和"说"究竟孰优孰劣?哪些新闻更适合"说",哪些适合"播"?本文分析"播新闻"和"说新闻"两种方式的语言特点、传播效果和规律等,以便更客观地去认识和运用这两种播报方式,提高新闻传播效果。

Making It Worse Than It Is: Quantitative Depictions of Threatening Trends in the News

An analysis of accident, crime, and health news reports sought to determine how story drama is increased by using quantitative data depicting threatening trends. These reports often used frequency data to characterize worsening trends and rate data to illustrate improving trends. Increasing magnitudes signified worsening trends, and decreasing magnitudes signified improving trends. Worsening trends and frequency data depictions were more likely to be accompanied by specific exemplars. Television stories showing worsening trends or those including frequency data were longer than those reporting improving trends or rate data. Newspaper story length was unrelated to trend direction or data type.     

Determinants of national media attention

This study employed two perspectives to investigate media attention given women congressional candidates. The first perspective is that media attention may be explained by typical and normal media processes, such as focusing on incumbents. The second perspective considers a partisan explanation in which media attention is weighted more to Democratic candidates than Republican candidates. This study employs two established sources, Vanderbilt's Television News Index and Abstract and Information Access's National Newspaper Index , to examine the national media attention of Democratic and Republican women congressional candidates in 1990 and 1992. The investigation determined that media attention is related to whether the candidates are running for the Senate or House, incumbency, and state population. The results also reveal that party is a statistically significant factor associated with media attention. The investigation also determined that ethnic candidates tend to receive slightly less attention from the print media than nonethnic candidates.

Are News Reports of Suicide Contagious? A Stringent Test in Six U.S. Cities

Past evidence of suicidal contagion from news reports in the United States is based largely on national data prior to 1980 using proxies for suicide stories rather than local news sources. Our research examined more proximal effects of suicide news reporting for 4 months in 1993 in 6 U.S. cities controlling for a wide range of alternative sources of media and interpersonal influence. In addition, predictions for the effect based on suicide contagion theories were examined for 3 age groups (15–25, 25–44, and older than 44). Local television news was associated with increased incidence of deaths by suicide among persons younger than 25 years. Newspaper reports were associated with suicide deaths for both young persons and persons older than 44 years. An unexpected protective effect of television news reports was observed in the 25–44 age range; nevertheless, news reporting was associated with an aggregate increase in suicide deaths. The results support theories of media contagion but also suggest that media depiction can inhibit suicide among some audience members.     

Multi-bend bus driven floorplanning

In this paper, the problem of bus-driven floorplanning is addressed. Given a set of blocks and bus specifications (the width of each bus and the blocks that the bus need to go through), we will generate a floorplan solution such that all the buses go through their blocks, with the area of the floorplan and the total area of the buses minimized. The approach proposed is based on a simulated annealing framework. Using the sequence pair representation, we derived and proved some necessary conditions for feasible buses, for which we allow 0-bend, one-bend, or two-bend. A checking will be performed to identify those buses that cannot be placed simultaneously. Finally, a solution will be generated giving the coordinates of the modules and the buses. Comparing with the results of the most updated work on this problem by Xiang et al. [Bus-driven floorplanning, in: Proceedings of IEEE International Conference on Computer-Aided Design, 2003, pp. 66-73], our algorithm can handle buses going through many blocks and the dead space of the floorplan obtained is also reduced. For example, if the buses have to go through more than 10 blocks, the approach in Xiang et al. [Bus-driven floorplanning, in: Proceedings of IEEE International Conference on Computer-Aided Design, 2003, pp. 66-73] is not able to generate any solution while our algorithm can still give solutions of good quality.

基于不确定非线性智能电网感知网络控制系统方法研究

针对传统的不确定时滞的鲁棒控制系统不能满足现代电力系统发展的需求,提出一种基于不确定非线性智能电网感知云网络化控制识别方法。使用传统的数据值和基于电力网络到网络系统模型作为电力感知网络到网络模型的电力云网络,控制数据优化使用电源感知网络,而不是利用控制节点的预测值,突破了鲁棒控制的不确定时滞系统的控制效果。运用感知模型中的正向云算法修正加权系数,仿真实验证明,该识别方法能够很好地优化传统的不确定时滞鲁棒控制电力系统,具有良好的适应性和鲁棒控制性,进一步提高了智能电网传感云网络控制的各项性能指标。
