新闻价值量化分析研究

不同的新闻学者和新闻工作者对新闻价值都有自己的看法,由于研究侧重点的不同,得出的结论也有很大的不同,甚至是相悖的。新闻价值虽然是个抽象的概念,但笔者相信,就像智商可以量化一样,可以尝试探索一套对新闻信息和新闻作品进行量化的标准。本文从量化的角度尝试对新闻价值进行分析,从可行性和必要性入手,分析可以量化的条件和原因。据此再对新闻价值量化进行探析并提出新闻价值偏差的概念,基于这个前提,再探讨新闻价值量化的意义。

Proximity and Framing in News Media： Effects on Credibility, Bias, Recall, and Reader Intentions

A writer＇s decision to localize a news article and the valence of the frame the writer employs can affect readers＇ perceptions of credibility and bias as well as readers＇ factual recall and the likelihood that readers would want to read the newspaper further. A 2 （proximity： local, non-local） ~ 3 （frame valence： positive, neutral, negative） factorial experiment （N = 136） tested the effects of proximity and frame valence on credibility, perceived bias, recall, and reading intentions. Articles that localized enjoyed greater perceptions of credibility but not recall, while articles with either a positive or negative frame yielded greater recall than articles with a neutral frame. Neither factor exhibited a main effect in predicting perceived bias, but their interaction was a significant predictor. In addition, localization and frame valence also influence the likelihood that participants would want to read the source newspaper again. Implications for theory and media practice are discussed.
