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。     

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.     

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。     

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。     

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.     

基于ANSYS的行李车改造成发电车的车架设计与分析

现代设计方法的发展和使用,使铁路车辆设计变得越来越快速高效。在行李车改造为发电车过程中,首先根据车架结构对车厢进行布局设计,其次运用有限元分析软件ANSYS对改造后的车辆车架系统从强度和刚度方面进行计算和分析。然后根据分析结果,使用APDL语言对车架薄弱环节和不合理结构进行改进。最后,对改造后车架进行模态分析和谐响应分析,确定有害频率和振型,并采取有效减振措施。从研究结果看,改造后的车辆车架能达到安全使用的设计目的。     

高校经管类学生参与科研意愿的影响因素分析——基于安徽省8所高校的问卷调查

大学生参与科研是高校培养双创型人才的重要途径之一,高校经管类专业学生培养存在重理论、轻实践的现象。安徽省8所高校1406名经济管理类学生科研意愿的实证分析表明:年级、学习成绩、科研重要性认知、科研了解程度和学校科研活动开展对大学生科研意愿有显著影响。高校在经管类学生培养过程中应通过加强科研宣传推广、开设科研训练课程、丰富科研活动多样性、激励教师科研指导和开拓校外实践教学基地建设等措施增强学生参与科研的积极性,提升学生的双创能力。
