FDI视角的环境库兹涅茨假说检验——基于中国中部八省的面板数据

环境库兹涅茨假说认为环境污染指标先随收入的提高而增加,而后随收入的提高而下降。本文利用1985-2008年中国中部八省大气污染、污水和固体废弃物（＂三废＂）等环境质量指标的面板数据,从FDI的视角对中国中部经济发展与环境污染关系进行了库兹涅茨假说检验。结果显示,中国中部八省没有严格意义上的倒U型环境库兹涅茨曲线,FDI对中部各省环境的影响存在差异,数据回归结果也没有支持污染天堂假说。     

输入输出理论在大学英语教学中的应用

输入与输出理论侧重点不同。在大学英语教学中应做到输入、输出并重,并结合读写课和视听说课的实际,采用大班授课和小班授课相结合的教学方式,并辅助网络多媒体自主学习,提高学生的语言运用能力。     

基于输入输出理论的高级英语视听说课程教学改革效果分析

在输入输出理论的指导下,改革高级英语视听说课程的教学内容与教学方法,将语言输入与语言输出放在同等重要的地位上,为学生提供语言实践的机会,提高了学生的语言运用能力。     

Linking Customer Engagement to Trust and Word-of-Mouth on Facebook Brand Communities: An Empirical Study

Given the rise of social networking sites, particularly Facebook, companies have started engaging with customers in this newly emerged digital space. This study explores the role of customer engagement in enhancing trust and word-of-mouth on brand communities over Facebook. The effect of customer involvement on customer engagement is also checked. This study also investigates the direct relationship of customer involvement with trust and word-of-mouth. A pen-and-paper questionnaire survey of 450 Facebook account holder students was used. Data were analyzed using structural equation modeling. The results reveal that a higher level of involvement with the brand community leads to a higher level of customer engagement. Customer engagement leads to customer trust and word-of-mouth activities. The results further suggest a direct positive relationship of customer involvement with trust and word-of-mouth, but the mediation of customer engagement strengthens the mentioned effect.     

金融发展的指标体系及其与经济发展的关系

理论界对金融发展的界定分为注重宏观质性金融发展的"功能观"和注重微观量性金融发展的"结构观",而"金融资源论"则兼容了两者,既研究金融发展的功能,也研究金融发展的结构。金融发展的量化依存一系列指标体系。金融发展与经济发展具有联动关系:一方面经济发展通过对金融系统提出不同需求,对金融发展具有基础性决定作用;另一方面金融的发展也通过其功能的完善对经济发展做出贡献。     

中继蜂窝网中基于负载均衡的中继节点选择算法

提出了一种中继蜂窝网络的基于负载均衡的中继节点选择策略(Load Balancing Rela y Selection,LB-RS)。根据每个用户的具体信道状况以及中继节点服务的用户数目,LB-RS 以分布式的方式为每个用户选择最优的中继节点。仿真结果表明,与基于单一物理层参数的 中继节点选择算法相比,所提出的中继选择算法综合考虑了物理层的信道状况以及MAC层 的资源与用户状况,有效地利用中继节点选择来实现小区内的负载均衡,获得了吞吐量性能 与用户公平性之间的折衷。     

Information Quality of Interim Financial Statements

Expressing concern about the Canadian capital market environment, Boritz (2006) suggested that the accounting and auditing profession may be paying limited attention to quarterly reports. This study investigates whether fourth‐quarter adjustments are significantly different from the previous three, thereby limiting the reliability or faithful representation of the firms' results for each quarter. This study includes four years (2003–2006) of quarterly financial information of 353 Canadian public companies. Our results indicate that the volatility of net income in each of the first three quarters is considerably lower than in the final quarter. While lower volatility can improve predictability, the resulting relevance may be limited. The low volatility of reported earnings in the first three quarters suggests that either earnings management is taking place or that management may not be exercising sufficient care at the end of each of the first three quarters on the measurements that generally accepted accounting principles call for and readers of financial statements expect. This could result in quarterly financial statements that do not faithfully represent the underlying resources and obligations of the reporting firms at the end of the quarter, or the firm's performance during the quarter. Our findings support Boritz's proposition for increased audit requirements for interim reports and changes in the approach to the annual audit to integrate it more closely with interim financial reporting.     

消费者涉入前因、涉入程度与购买意愿间关系的实证研究

消费者涉入程度的高低受到多种涉入前因的影响,而且涉入程度与购买意愿之间呈显著相关;涉入前因中营销刺激与个人兴趣与涉入程度呈显著相关,其他因素一般相关或微弱相关;涉入程度在消费者行为中是中介变量。笔者基于我国市场的特性和消费者行为的差异,验证了这些变量之间的关系,得出营销刺激是最大正向影响因素;在营销实践方面,验证了在现今的市场环境中"酒香也怕巷子深"现象。因此企业要以消费者需求为导向,制定整合营销传播策略,实施有效营销。     

Health and environmental consciousness,costs of behaviour and the purchase of organic food

This paper examines environmental and health consciousness, as well as behavioural costs and their effects on the purchase of organic products. The consumption of organic products is regarded as an investment in individual health. The low‐cost hypothesis takes environmental attitudes and behavioural costs into account and is applied to organic food consumption. The survey conducted in three German cities in 2006 using self‐administered questionnaires (n = 521) does not investigate willingness to pay but rather self‐reported behaviour. The results of the regressions using the Heckman correction show that income does not affect the regularity of organic food consumption but that it does influence individual expenditure on organic food. Furthermore, there is an inverted u‐shaped relation between age and the purchase of organic products. Although health consciousness has a stronger association with organic food consumption than does environmental concern, the interaction between behavioural costs and health or environmental consciousness shows no effect. Thus, the low‐cost hypothesis is not supported.
