传播议程经济的乘数效应

传媒经济的实质是议程经济,只有议程经济可以联系传媒传受即供需双方,实现传媒经济均衡。议程经济发挥作用的机制是传播的乘数效应,在传统媒体和新媒体融合的生态下,媒介生产方式体现出全新的特征。信息的倍增效果产生的正反作用对传播的议程经济的取得提出了新的挑战,值得高度重视,有必要深入研究以网络信息传播为代表的新媒体的规制原则和方法,才能确保传媒经济和社会双重效益的实现。     

“信息乐园”对当代社会伦理的冲击和反思

信息网络开辟了人类新的时空隧道,掀起一场全人类信息化的思想"冲浪", 其中不乏新的机遇,也难免迷乱和冲突.加强网络信息伦理教育,提倡网民"自省"、"慎独" 以及完善网民信息行为的赏罚机制,能加强"信息乐园"的道德建设.     

出生率变化对高等教育的影响研究

建国以来,我国出生率发生了重大转变,随着90年代以来人口出生率的逐年下降,我国高等教育将面临学生数量下滑趋势,未来高等院校将会出现生源不足的困境。但是,由于目前我国高等教育入学率还比较低,加之政府财政时高等教育支持的力度也还有很大提升空阅,因此,尽管出生率会不断下降,但对高等院校整体上生存不会受太大的影响。

New V control chart for the Maxwell distribution

Control charts have been popularly used as a user-friendly yet technically sophisticated tool to monitor whether a process is in statistical control or not. These charts are basically constructed under the normality assumption. But in many practical situations in real life this normality assumption may be violated. One such non-normal situation is to monitor the process variability from a skewed parent distribution where we propose the use of a Maxwell control chart. We introduce a pivotal quantity for the scale parameter of the Maxwell distribution which follows a gamma distribution. Probability limits and L-sigma limits are studied along with performance measure based on average run length and power curve. To avoid the complexity of future calculations for practitioners, factors for constructing control chart for monitoring the Maxwell parameter are given for different sample sizes and for different false alarm rate. We also provide simulated data to illustrate the Maxwell control chart. Finally, a real life example has been given to show the importance of such a control chart.     

Monitoring the coefficient of variation using a variable sample size and sampling interval control chart

This article proposes a CV chart by using the variable sample size and sampling interval (VSSI) feature to improve the performance of the basic CV chart, for detecting small and moderate shifts in the CV. The proposed VSSI CV chart is designed by allowing the sample size and the sampling interval to vary. The VSSI CV chart's statistical performance is measured by using the average time to signal (ATS) and expected average time to signal (EATS) criteria and is compared with that of existing CV charts. The Markov chain approach is employed in the design of the chart.     

Social impacts evaluation and insider-outsider paradigm: Floodwater spreading project on the Gareh-Bygone plain as an illustrative case

Selection of the appropriate social impact evaluation approach has become an important issue in agricultural and rural development projects in developing countries. The aim of this research was to use the lens of insider-outsider or mutual social impact assessment approach to assess the social impacts of floodwater spreading project (FWSP) on the Gareh-Bygone plain, Iran. A survey methodology with systematic sampling techniques was used to select 138 households as insider group in four villages’ of the Gareh-Bygone plain which is covered by FWSP. Furthermore, key person interview was used to assess the viewpoints of experts (outsider group) who had close, ongoing involvement with the project. Result indicated that the experts’ viewpoints were more positive towards social impacts of the project. Whereas, the project had some negative and positive social impacts from the local people point of view.     

从“凯恩斯效应”到“阿米曲线”——政府规模与经济增长关系的非线性转向

政府规模与经济增长之间的关系问题是宏观经济研究中的核心问题之一.关于两者关系的传统研究往往以线性假定为基础,所以实证结果出现了巨大的差异.这种现象促使研究者从非线性角度重新审视政府规模与经济增长之间的关系.“巴罗法则”在内生增长框架内为政府规模与经济增长关系研究提供了一个标准的分析框架,揭示了两者之间的倒“U”关系.而“Armey曲线”不仅非常直观地表达了政府规模与经济增长之间的非线性关系,同时还指出这种非对称关系的非对称性质,具有很强的总结性和政策指导意义.     

农村剩余劳动力转移对下岗人员再就业的冲击

农村剩余劳动力转移和下岗问题是全社会普遍关注的问题,农村剩余劳动力的转移时下岗职工再就业产生了不少的压力,形成了一种激烈的竞争关系,造成下岗职工再就业难度加大的局面。本文在描述农村剩余劳动力的转移对下岗人员带来冲击的同时,也分析了下岗人员受到冲击的原因。通过对农村剩余劳动力和下岗人员情况分析,意在剖析下岗人员失业的原因以及在市场经济条件下如何缓解农村剩余劳动力转移对下岗职工再就业冲击的问题。     

新自由主义思潮及其对我国的影响

新自由主义作为一种经济思潮,最早兴起于20世纪30年代,它以反对国家干预“凯恩斯主义”理论的面目出现,兴盛于资本主义的“滞涨”时期。随着70年代末80年代初英国撒切尔夫人、美国里根总统的相继上台,这一思潮逐渐成为西方资本主义国家主流的经济意识形态,苏联解体后,美国等资本主义国家加速向发展中国家推行这一思潮,引导这些国家进行自由主义改革,导致这些国家相继出现社会动荡和经济危机。改革开放以后,我国在引进西方先进科学技术的同时,这一思潮也趁虚而入,在国内造成了很大的负面影响。通过考察新自由主义思潮的发展及其对我国的影响,力图让人们看清新自由主义的资产阶级意识形态的本质,并自觉加以抵制。
