虚拟仪器技术对知识创造的影响研究

仪器作为现代科学研究的核心组成部分，在很大程度上决定了科学知识的产出。虚拟仪器技术对知识创造产生了深远影响。“软件就是仪器”的理念使得传统仪器、测量观念以及仪器作为科技黑箱的内涵和功能发生了质的变化。虚拟仪器在集成大量编码知识的同时更多地集成了主体的隐性知识，虚拟仪器技术通过对主体知识体系的重塑影响了知识创造。主体只有通过长时间、复杂的学习和使用过程才能充分发挥虚拟仪器技术在知识创造中的优势，实现编码知识和隐性知识的共同增长。     

财务危机成因分析

随着当今市场环境的复杂多变和国际竞争的日益加剧,企业面临着越来越大的风险和危机,而财务危机是企业危机中最显著、最综合的表现。对企业的财务危机进行管理,必须首先在国内外学者研究成果的基础上对企业产生财务危机的原因进行分析。其外部原因主要分为宏观环境和行业环境,其内部原因主要包括管理失误、治理结构不完善、为其他公司提供担保这几大方面。     

A股市场均线策略有效性与收益率随机特征研究

本文使用上证指数1990年12月到2011年12月的数据对均线策略有效性进行了分析。我们发现,(1)均线规则下,投资者能够获得超额收益率,且买入交易日的平均收益率显著高于卖出交易日的收益率;(2)不同期限的均线策略所获得的收益率随市场环境的变化而变化,这是由各期限均线策略在不同市场环境中风险的变化所导致的;(3)增加缓冲空间提高了买入交易日的收益率均值,同时降低了卖空交易日的收益率均值,这一结果同样是由缓冲空间所引起的风险变化所导致的。基于随机游走模型、ARMA模型以及GARCH-M模型的Bootstrap检验结果进一步表明,均线交易策略产生的收益率绝对值大于上述三个模型所得到的"正常"收益率的绝对值,这三个常用的模型无法解释移动平均策略所获得的收益率。     

Motivations and Barriers to Corporate Environmental Management

This paper integrates two conceptual frameworks, utility maximization and institutional theory, to analyze voluntary corporate environmental management. The utility maximization or economic approach centers on motivations to decrease cost, increase revenue and improve manager utility. Institutional theory emphasizes how external pressures from market and non‐market constituents shape the firm's environmental efforts. We view the two frameworks as complementary and postulate a model that includes both types of influences. Survey data from six major industries consisting of a diverse set of facilities are used to estimate the effects of economic and institutional factors on a facility's use of environmental practices and pollution‐prevention activities. Our results support the hypothesized model, and show that cost barriers, management attitudes toward environmental stewardship, company ownership and external institutional forces, including competitiveness, investor and regulatory pressures, all affect a facility's environmental practices and pollution prevention activities. Findings suggest that a multifaceted policy strategy is needed to advance corporate environmental management across diverse firms. Copyright © 2012 John Wiley & Sons, Ltd and ERP Environment

Involvement theory in constructing bloggers' intention to purchase travel products

Blogs recently have demonstrated their enormous marketing potential, and more and more travel advertisements are being posted in blogs. In light of this observation, this study aims to provide insights into the structural relationship among travel bloggers' involvement level, the advertising effect from blog messages, and travel bloggers' intention to purchase travel products. A travel blogger's purchase intention model was constructed and empirically tested. A total of 900 questionnaires were distributed to identified travel bloggers; 398 valid responses were returned. The data were examined with Structural Equation Modelling (SEM). The results demonstrated the positive impact resulting from the ad effect as well as the ad effect on purchase intention, which could be verified in travel blog environments. It also indicated that high-involvement travel bloggers are more likely to form favourable impressions with regard to ads in travel blogs. Travel blogs play a positive role in the processing of ad messages; brand management is essential to business marketers since brand attitude is the most influential factor related to the ad effect on purchase intention. Meanwhile, while ad attitude is not significantly effective concerning purchase intention, it remains essential in forming brand attitudes. Several implications for posting advertisements in travel blogs will be discussed and suggested in this paper.     

基于感应认知原理的汶川灾区黑色旅游资源开发探讨

“5．12汶川大地震”的发生，使灾区人民的生命财产、灾区的社会经济与产业结构遭受毁灭性破坏。目前灾后重建工作正在开展，黑色旅游作为一种与死亡、痛苦、恐怖、灾难等相关的新兴旅游活动，国外黑色旅游开发的经验对汶川灾后重建工作具有一定的借鉴意义。基于行为地理学中的感应-认知原理总结感应认知与旅游行为过程模式。进而分析潜在旅游者对汶川黑色旅游地的感知映像与旅游动机，并提出以旅游者旅游动机与需求为导向的汶川黑色旅游资源开发思路，以期对灾后重建工作的开展和国内黑色旅游的研究有所裨益。     

高层住宅含钢量新旧规范对比研究

随着房地产经济环境的变化,房地产开发商愈加重视结构的经济性和含钢量对造价的影响。2011版结构新规范的执行对结构的含钢量指标变化较大,直接影响结构经济性。本文根据新规范的实施,实例统计地震烈度6度区高层住宅含钢量的变化,统计建筑面积、钢筋级别、抗震等级在高层住宅中的影响情况,并且分析了含钢量的统计影响因素,以提供资料数据予房地产开发商造价控制以及结构工程师的结构优化。分析结果表明,新规范的执行使得含钢量和混凝土用量均增加5%以上,其影响不可忽视。     

新公共服务理论视角下中国旅游景区票价的政府管理

面对不断攀升的旅游景区门票,人们不断提出种种质疑。加强景区票价的政府管理,是促使其回归公益属性的重要途径。基于新公共服务理论分析当前地方政府在旅游景区门票管理中存在的问题,可以从门票的定价、经营方式的转变以及社会公众管理参与度的强化等方面加强景区门票的有效管理,以真正保障旅游资源的公益性。
