景气指标分类是景气预测法中至关重要的环节.在以往的文献中,一般采用一种方法对备选指标进行景气分类,但其结果还存在优化的空间.文章采用四种典型的景气指标分类方法:峰谷对应法、时差相关分析法、K-L信息量法、灰色关联度指标分类法对同样的多个指标进行分类.按照初定方案对四种方法的结果进行综合分析,对结果进行优化调整,应用实例表明:四种方法的优化调整结果比单一方法的结果更合理、更有效、更具有科学性.  相似文献

In order to broadcast an alert message from the accident site to the control center as soon as possible, the roadside units (RSUs) act as the critical component in vehicular ad hoc networks (VANETs). It is not possible to make a pervasive RSU deployment due to the huge cost and market requirement. Hence, how to deploy a minimum number of RSUs in a given region becomes a challenge problem. In this paper, we present an analysis for the total delay of broadcasting alert messages in VANETs along highways. Based on the analysis, the relationship between optimal number of RSUs with the highway distance is given. Moreover, the experiment results verifies the delay analysis and the optimization of RSUs deployment.  相似文献

Previous research has examined the impact of computing interventions to reduce digital inequity. However, few studies focus on factors such as inequalities to material access, Internet use patterns, and affective or emotional anxiety. This paper investigates the potential role of emotional costs and computer self-efficacy in the connection between computer use at home and students’ computer use patterns. Data for this research come from pretest and posttest surveys administered to fourth- and fifth-grade African-American students. The results reveal that students’ home computer use is a significant predictor of the change in their information and entertainment usage over the course of the intervention. Students’ emotional costs partially mediate the relationship between home computer use and information-oriented usage over the intervention period. The findings suggest that providing students access to digital devices is not enough to close the digital divide.  相似文献

时值"中国电影新力量"初成之际,作为"新力量"重要组成部分的新生代观众群体对这股发展大潮是不可或缺的。新生代观众以80、90后为主,这一代是娱乐化、网络化与个性化的一代。当下中国电影为让新生代观众能够透过影像移情入梦,便依据新生代观众独有的新特性,在复制真实、隐藏真实和制造仿像三个阶段中,充分运用各种艺术与技术的手段来满足他们的观影心理诉求,以保证电影票房的持续增长。  相似文献

In this study, we develop nonparametric analysis of deviance tools for generalized partially linear models based on local polynomial fitting. Assuming a canonical link, we propose expressions for both local and global analysis of deviance, which admit an additivity property that reduces to analysis of variance decompositions in the Gaussian case. Chi-square tests based on integrated likelihood functions are proposed to formally test whether the nonparametric term is significant. Simulation results are shown to illustrate the proposed chi-square tests and to compare them with an existing procedure based on penalized splines. The methodology is applied to German Bundesbank Federal Reserve data.  相似文献

This paper investigates the individual and combined factors affecting the extent to which corporations respond to crisis events consistently, in a timely manner, and actively. The determinants examined include public relations autonomy, legal dominance, strategic orientation, and organizational factors. A survey was conducted of communications mangers, public affairs personnel, and public relations personnel, drawn from the top 500 companies operating in Taiwan. Results indicate that the relative effect of individual sources of influence on crisis response is greatest for situations in which public relations departments have the most autonomy, followed by those where crisis management is handled with a strategic orientation, those where the legal departments dominate, and those where organizational factors provide the main avenue of address. The results emphasize the intriguing role of public relations autonomy by demonstrating its significant impact on providing a consistent, timely, and active crisis response. The strategic orientation of situation analysis also predicts a consistent response, whereas legal dominance predicts strategic ambiguity or inconsistent communication.  相似文献

Many researchers have explored how people share and construct similar mental models in teams. They have claimed that successful team performance depends on a shared mental model of team members about task, team, equipment and situation. Most of the literature has illustrated simplified relationships between a team's mental model and their performance without a valid instrument addressing the confined and relevant constructs of a shared mental model. This paper describes the instrument development steps and the conceptual framework for factors associated with shared mental models. After development and refinement, the instrument was finalized for use to measure team-related knowledge. The final instrument consists of 42 items that are linked to the five emergent factors of shared mental models including general task and team knowledge, general task and communication skills, attitude toward teammates and task, team dynamics and interactions, and team resources and working environment.  相似文献

当前社会工作服务在国家政策支持和社会现实需要下得到了迅猛的发展,而社会工作教师纷纷通过成立机构来承办各项政府购买服务,此现象是利是弊?社会工作教育者理论上要做到教学、科研和实习结合(为三元模式),但发展三元模式存在着资金、师资和验证成效等的困难。本文将就此探讨社工教师承办社工服务的现状,并通过应用珠海经验,探讨如何利用机遇,推进社工教育的三元结合模式。  相似文献

《国务院关于支持河南省加快建设中原经济区的指导意见》的出台,为郑汴一体化提供了新的发展契机,国际国内产业转移加快了郑汴一体化的进程。工业中各行业的静态和动态集聚指数分析表明,郑州和开封是实施一体化的理想区域:1.无论是从历史上还是从现实来看,郑汴两地更多地体现的是一种区域分工关系,而不是竞争关系。2.在一体化发展过程中,郑汴集聚的非优势产业和优势产业,是两地快速成长的产业,在产业内和产业间会形成规模经济-分工。3.郑汴产业对接不是单方向的开封对接郑州,而是存在着郑州对接开封、开封对接郑州和郑汴相互对接等三个层面。4.郑汴一体化使两地所获得的利益并不对等,郑州汲取了郑汴一体化的大部分利益,而开封有进一步被"空心化",进而沦落为落后产能承接地的危险。  相似文献
