中国货币财政政策有效性的比较检验

货币政策和财政政策是政府干预宏观经济最重要、使用最频繁的两大工具。改革开放以来,我国政府综合运用货币政策和财政政策调控经济运行,促进经济增长。为检验中国1978～2006年间经济增长中货币政策和财政政策有效性的差异性特征,应用脉冲响应函数研究它们之间的动态特性后发现:无论是短期还是长期,积极货币政策对于经济增长均有正效应,而积极财政政策仅在短期内有效,长期内呈现负效应且随时间推移逐渐显著。积极财政政策长期失效的原因有多方面,主要是财政支出的供给范围不合理和支出管理失控产生的效率损失。     

男性犯罪青少年人际信任与社会支持、应对方式的关系研究

通过对山东省少年管教所189名男性犯罪青少年人际信任的特点以及与其社会支持、应对方式的关系进行研究发现:(1)男性犯罪青少年人际信任水平比同龄男性中学生低,且差异显著;(2)其社会支持与人际信任水平呈正相关;(3)积极应对方式与人际信任水平呈正相关,消极应对方式与人际信任水平呈负相关;(4)人际信任、社会支持和应对方式之间存在复杂的因果关系;(5)各种客观变量对人际信任的影响甚微.     

论《傲慢与偏见》反讽色彩在译本中的欠额翻译

反讽可以达到戏谑、嘲弄及讽刺的效果,使作品生动幽默,富有艺术感染力。反讽在《傲慢与偏见》中塑造了鲜活的人物形象,使作品妙趣横生,令读者百读不厌。因此,成功的译文必须将其完全再现出来。然而,在阅读三个中文译本的过程中发现存在反讽的欠额翻译现象。从语言学角度分析了其原因,并给出了新的翻译建议,指出译者不仅要具备足够的源语文化和语言知识,还必须具有熟练驾驭目标语的能力,才能避免反讽的欠额翻译,达到译语读者和源语读者反应的对等。     

An improved cluster two-stage randomized response model

In this paper, Abdelfatah and Mazloum's (2015) two-stage randomized response model is extended to unequal probability sampling and stratified unequal probability sampling, both with and without replacement. The extended models result in more efficient estimators than Lee et al.'s (2014) estimators of the proportion of the population having a sensitive attribute.     

称赞语应答的语体特征分析

称赞语的应答是常用的交际技巧,但是制约应答方式的因素却有很多,要做到应答得体在一定程度上非常困难。本文通过分析称赞语应答的语体特征的构成、对称赞语回应的影响和作用,从中找出称赞语回应的共同特征和应该遵守的潜规则,指导人们如何在交际中得体回应别人的称赞。     

鲁迅与波德莱尔的话语共鸣

《野草》和《巴黎的忧郁》是鲁迅和波德莱尔的散文诗集,两位伟大的作家选择了相同的文体,运用象征手法,选择特有的意象,表达时代的抑郁和苦闷。由此形成了两者的话语共鸣,体味出新的审美典范。散文诗以其特殊的话语形态表达作者的心理情感及其想像空间,鲁迅与波德莱尔一方面具备写作散文诗的特质,另一方面时代也促成了他们选择这样的话语形态,由此透过两位大作家的文字,我们体味到两者文本之中的话语共鸣——精神的忧郁、心灵的苦闷;同时也体味到世界文学的共鸣。     

物联网在灾害救助物资管理中的应用

救援物资的管理是应急管理中的一项重要工作,物联网的泛在性特别适合用于救援物资的管理。物联网在应急物资管理中的应用可以分为针对静态信息、动态信息的管理,也可以根据不同的应急管理阶段进行划分,在事前准备、事中救助、事后分析等三个阶段发挥作用,以上分析将为物联网技术应用于救灾物资管理提供具体的指导和部署意见。     

Churning races in Canada: Visible minority response change between 2006 and 2011

Why do most people have stable responses to census race questions, while some do not? Using linked Canadian data, we examine personal, social, and economic characteristics that predict response stability as White or as one of six large visible minority groups, versus a change in response to/from White or to/from another visible minority group. Response change rates in Canada are generally comparable to those in the US, UK, and New Zealand. Likely reflecting the centuries-old hegemony of Whites in these countries, White is the most stable response group in Canada as well as the US, UK, and New Zealand. Multiple-race response groups are among the newest and least stable response groups. Social statuses and experiences (mixed ethnic heritage, immigration status, and exposure to own-group members) are generally more predictive of race response stability and change than economic (income level and change in income) or personal statuses (education, age). This highlights the socially-constructed nature of race group boundaries. Joining and leaving a group are often predicted by the same status/characteristic and in the same direction, hinting that the status/characteristic adds complexity to the race-related experiences of constituents.     

Narrative persuasion,identification, attitudes,and trustworthiness in crisis communication

The purpose of this study is to test the effects of narratives in crisis communication. This research assesses how organizations benefit from using stories in their media responses, relative to sharing nonnarrative information. The theory of crisis response narratives (Heath, 2004) holds that ethical narratives are effective because they enhance trustworthiness, attitudes toward the spokesperson, and identification with the spokesperson. Normative crisis communication theory exhorts disclosing truthful information rather than spinning. In an online experiment, participants (N = 365) watched a news interview in which a scandalized company’s spokesperson responded to a journalist’s questions with (a) ethical narratives, (b) unethical (spin) narratives, or (c) nonnarrative information. Multiple mediator modeling assessed identification with the spokesperson, attitudes toward the spokesperson, and perceived trustworthiness of the spokesperson. Results indicate ethical narratives are more effective than unethical narratives. However, nonnarrative information most effectively enhances trustworthiness and bolsters identification.     

基于时频分析的裂纹转子碰摩故障特征研究

为研究转子系统耦合故障特性,采用有限元方法建立了含有横向裂纹、转静碰摩的非线性转子动力学模型。首先研究了不同转速下裂纹、碰摩单一故障下转子系统的振动响应,其次研究了两种故障耦合情况下系统的振动响应特征。采用波形图、FFT谱图、瞬时频率和Hilbert-Huang时频谱(HHS)相结合的方法对故障转子振动信号进行了分析。分析结果表明:运用多种时频分析相结合的方法可以较为全面地了解转子的故障特征,裂纹转子在1/5、1/3临界转速时会发生较为明显的5X、3X谐波,且裂纹的产生会导致响应幅值增大,从而引起更为严重的碰摩。 
