寻呼发射机是无线寻呼系统中的关键设备之一,针对其可靠工作和安全运行问题,提出了一种专用远程监控系统,介绍了智能寻呼发射机监控系统中的系统组成和系统功能,并论述了系统的硬件设计方案,从地址码和遥控命令集的设计等方面分析了系统中遥控遥测的实现原理,并重点讨论了系统为保障数据安全而采用的 IDEA数据加密算法与 MD5报文鉴别等关键实现技术。现场测试表明,该监控系统对提高寻呼发射机运行的安全性和可靠性具有重要作用。     

农村贫困人口瞄准中主体博弈行为的分析

信息不对称导致农村贫困人口瞄准中的政府、政府专门的扶贫机构与基层扶贫组织之间形成委托代理关系,进而出现两大博弈过程。基于扶贫机构工作认真负责与否,建立政府、扶贫机构和扶贫对象三大主体之间的博弈模型,并通过博弈模型的最优解提出提高农村贫困人口瞄准精度的建议：建立农村贫困人口的信息披露制度;保障督查的积极性,注重督查的效率;物质奖励与精神奖励并重;强化扶贫工作责任制等。     

Generalized Poisson integer-valued autoregressive processes with structural changes

In this paper, we introduce a new first-order generalized Poisson integer-valued autoregressive process, for modeling integer-valued time series exhibiting a piecewise structure and overdispersion. Basic probabilistic and statistical properties of this model are discussed. Conditional least squares and conditional maximum likelihood estimators are derived. The asymptotic properties of the estimators are established. Moreover, two special cases of the process are discussed. Finally, some numerical results of the estimates and a real data example are presented.     

短信文化的二律悖反性

手机短信的传播方式不同于大众传播方式,它呈现出一种二律悖反性。短信传播使人与人之间的接触变得更自由,但同时又扩大了人和人之间的距离;短信使人际交往的机会和频率不断增多,但是带来了人与人之间感情的疏离。     

广告信息框架与信息目标对受众亲社会行为的影响研究

为研究亲社会行为广告效果的影响机制,从调节聚焦理论出发,选取社会生活中常见的“公交让座”情境,设计2(受众的调节聚焦特征∶促进聚焦/防御聚焦)×2(信息目标∶自己/他人)×2(信息框架∶损失/获得)心理学实验室实验,研究不同亲社会行为广告信息策略的影响.结果发现,“获得”信息框架对促进聚焦人群亲社会行为意向有积极影响;“损失”信息框架对防御聚焦人群亲社会行为意向有积极影响;信息组合策略强调“他人损失”时对防御聚焦人群亲社会行为意向的积极影响更显著.     

Over-emoting and perceptions of sincerity: Effects of nuanced displays of emotions and chosen words on credibility perceptions during a crisis

This study focuses on understanding how words and discrete facial emotions influence credibility perceptions of both prepared statements and spontaneous question and answer sessions. We build on and extend existing theoretical work concerning crises communication and discrete emotions. Using a press conference simulation, spokesperson video recordings were analyzed using automated face-emotion recognition software (FaceReader™) to characterize discrete emotions. A crisis-message-strategy trained dictionary for Linguistic Inquiry and Word Count (LIWC) was used to characterize message content. Our results indicate that spokespeople can control their verbal messages better in prepared statements than in more spontaneous settings, but their facial emotions are quite similar in both settings. Only three discrete emotions are related to credibility perceptions: anger, sadness, and surprise, but sadness and surprise are not universally viewed positively or negatively. Expressing too much emotion, or over-emoting, is problematic. Expressing more anger in the Q&A, which we refer to as reactive anger, is perceived negatively, and when spokespeople emote a low amount of sadness and use a high amount of words expressing sincerity they are viewed as having the most credible messages.     

Non‐take up of the supplemental child benefit for children with a disability in Belgium: A mixed‐method approach

Families with disabled children run a great risk of being poor. Although policies providing poor families with financial benefits should be effective in reducing poverty, the actual effectiveness is often jeopardized by the issue of non‐take up (NTU). Yet, NTU of benefits aimed at disabled children is for the most part uncharted territory. In this article, we fill this gap using a mixed‐methods approach to (a) estimate the magnitude and characteristics of NTU in the Belgian “supplemental child benefit” by drawing on a large‐scale administrative dataset on childhood disabilities and (b) explore the determinants of NTU by means of semistructured interviews with experts and parents. We estimate an NTU rate of at least 10%, a substantial figure given that the benefit is not income tested. This mainly concerns children with “less visible disabilities” (autism spectrum disorder and other intellectual and psychological disorders) and results from insufficient information provision about the benefit's existence and eligibility criteria; process costs, for instance, the complexity of the procedure; and the way the scale to assess a child's disability is constructed.     

青年短信文化的探寻

追逐时尚的青年“手机族”,创造了新的“第五媒体”——短信新文化。信息联络、祝福传情、幽默调侃、评论宣泄;拓展交际、追求时尚、获得认同、彰显个性、缓解压力;新生活方式的“快乐”与“陷阱”并存。对青年短信文化要作积极的引导。     

英汉口译信息解码中的语义噪音干扰及排除

口译的过程实际上是一个语言间的信息传递过程,涉及到译员解码和用译出语再编码。根据信息传播理论,信息的传播质量受物理和语义噪音的干扰。在英汉口译中,语义噪音干扰了译员对原语的言内、言外信息解码的准确性。要最大程度排除语义噪音的干扰,译员必须提高跨文化意识,做到从源语文化的角度解码信息;加强语境的识别能力,在具体的语境中识别语义,排除语义噪音干扰;树立语域意识,提高预测能力,降低语义噪音的干扰。     

挪威福利原则与改革趋势：社会权将更具条件性？

人们将“北欧福利模式”视为西方福利国家的一种独特模式。北欧模式的一个主要特征是社会保障、健康以及惠及全民的教育政策,换句话说,即基于普遍性原则的社会政策。近期的改革趋势不得不令人质疑：普遍性原则当前在挪威这个福利国家是否受到了威胁。大体上,福利国家都以不同的规范、价值观和原则为基础。从几种主要福利原则可以看出,在现代北欧与欧洲其他福利国家近期改革中,重心从普遍性原则转移到更强调互惠性与标的设定原则。后两者更侧重合同、义务和激励措施,以使人们为个人幸福承担更多责任。
