战略传播的“环境设置”效应

战略传播是美军在公共外交的基础上提出的新型军事传播理念,现已广泛延伸到政治、经济、文化等领域。本文提出,从战略层面着眼,把长远地部署传播体系,对关键目标受众的决策环境进行影响和塑造所实施的传播行动称为“环境设置“。环境设置突出了两个概念,一是战略传播对关键目标受众决策“环境“的着力,二是围绕预期目标针对特定受众思想和行为进行间接“设置“的思路。从这一点上看,战略传播的首要预期作用,也正是制造“环境设置效应“

论新闻与公共关系

新闻与公共关系从一开始就是既相互依存又相互对立的。从实务界到学界,关于新闻与公共关系二者应该互斥还是合作的争论持续了多年。然而,从现实以及未来发展趋势看,随着现代社会组织化程度的不断加深,记者和媒体对作为消息源的组织依赖也日益加深,公共新闻学理论和现代公关理念的渐行渐近,使新闻与公共关系的合作成为必然。新闻与公共关系都是社会的润滑剂。告知真相、建构社会,正在成为新闻和公共关系的共同目标

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel

JUNO sensitivity on proton decay p → ν K + searches*

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the $p\to \bar{\nu} K^+$ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar{\nu} K^+$ is 36.9% ± 4.9% with a background level of $0.2\pm 0.05({\rm syst})\pm$$0.2({\rm stat})$ events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is $9.6 \times 10^{33}$ years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
