心理距离视角下网络舆情传播意愿影响因素研究 总被引:1,自引:1,他引:0
[目的/意义]网络舆情传播意愿的形成是网民的一种心理活动,与心理距离密不可分。了解影响网络舆情传播意愿的主要因素,有助于监督管控部门更加卓有成效地对网络舆情进行预警和治理。[方法/过程]通过对心理距离理论的深层次剖析,对其构成进行阐述,并从时间距离、空间距离、社会距离、概率4个维度出发,做出系列理论假设,利用调查问卷法和最优尺度回归分析法,识别出主要影响因素及其重要程度。[结果/结论]最终归纳出7个影响网民改变其自身传播意愿的主要因素,即报道时间、家乡相关、向往地相关、生活相关、亲戚朋友发布、媒体官方发布、企业官方发布,从这7个影响因素出发监控舆情,可以帮助舆情管控部门更有针对性地掌控舆情的传播方向。 相似文献

The purpose of this research is to illustrate the use of the gamma distribution to model the ages of references in published research, and to demonstrate that the two gamma distribution parameters characterise a field of research in a manner that is complementary to and more nuanced than the Price Index or mean age of references.Minimum Distance Estimation is shown to produce robust estimates of the gamma distribution parameters because of the insensitivity of the Kolmogorov–Smirnov test in the tails of the distribution.Using a sample of 816 articles from 26 different journals across six subject areas, it is shown that the gamma distribution is at least as good as a lognormal distribution to model the ages of references in research articles.The two gamma distribution parameters indicate the rate of publication of new knowledge within the respective discipline and the citing behaviour in terms of the recency of references. Interpretation of these gamma distribution parameters enables a more nuanced and granular interpretation of the distinctiveness of disciplines, sub-disciplines, formats of publication and the distribution of references within articles than possible using the Price Index, half-life or mean age of references. 相似文献

流媒体DRM技术在现代远程教育中的应用 总被引:1,自引:0,他引:1
Internet的飞速发展及广泛应用为各种信息资源的传输提供了一个可靠、高效的技术平台,开放式的现代远程教育在此基础上应运而生逐渐成为现代教育的重要组成部分.流媒体技术解决了人们通过网络下载、传输信息的带宽和时间的问题,通过采用高效的信息传送技术, 远程教育突破了传统课堂中时空的限制,实现了教学资源的共享.然而,多媒体课件是远程教育中最重要的数字作品,是其核心价值之所在,网络的开放特征势必造成多媒体课件任意破坏,版权人的合法权益将严重受损.本文试图通过流媒体DRM技术的利用来达到保护数字内容的版权目的. 相似文献

This case study presents the development and implementation of a personal librarian program for a cohort-based, executive-style higher education administration doctoral program. Librarians and the program director collaborated to create a student-centered program based on individual research needs. The personal librarian program was designed to build a close relationship between the librarian and individual students; to help identify their research knowledge gaps; and to identify resources to meet each individual students' research needs. 相似文献

Many librarians struggle with how to balance scalable instructional offerings with more personalized instruction for online students—scale tends to come at the cost of personalization and vice versa. This paper will discuss three methods for connecting with online students that range from one-to-one personalization to widely scalable instruction: individual consultations, scaffolded instructional webinars, and asynchronous video tutorials. The student engagement with each type of instruction will be discussed, with ideas for future directions provided. 相似文献
