Three denim jeans products from the same manufacturer with differentiated pricing and labels (antiqued, sandblasted, and stonewashed) were used to determine the relationship between price and quality. Both qualitative and quantitative procedures were used to analyse the garments. All three jeans were made of twill weave with 3 × 1 repeat. Both structural and performance characteristics were compared using standardized tests. Analysis of variance was used to compare the selected structural and performance characteristics among the three jeans products. Tukey’s HSD tests were used for post hoc multiple comparisons for three jeans. The findings revealed that despite the fact that all three jeans products were from the same store, and that the fabrics used the same weave, degree and direction of twist, the jeans differed significantly for several structural and performance characteristics. Several possibilities for future research were explored.  相似文献

本文通过调整迭代解码过程中系统位接收值的加权系数,提出了一种Turbo码加权迭代解码算法。该算法改变了迭代运算后Turbo码解码器输出软值中系统位接收值信息和它的外部估计信息的比重,使Turbo码无论在低信噪比或是在高信噪比时均具有优良的纠错性能。仿真结果显示,采用Turbo码加权迭代解码算法,不仅能提高Turbo码的收敛速度,而且能进一步降低Turbo码解码时的地板值,使Turbo码的比特误码率在高、低信噪比时都能够得到进一步改善。  相似文献

Many textbooks on project management present illustrations concerning the relative size of project attributes during different project phases. The derived models all have attributes in common, such as uncertainty, significance of decisions, and degree of freedom to maneuver, that are typically high in the beginning of the project and low in the end. At the same time, variables such as the accumulated cost and available information begin at low levels and end up at a high level at the end of the project. Based on empirical data from projects, this paper illustrates and quantifies one of these attributes, the freedom to maneuver, in different project phases.  相似文献

Using news media as a reliable source, we content analyzed stories on business leaders in two major official Chinese newspapers in three different time periods over the past 20 years. Results show that the reform has brought an increase in stories of business leaders, and in coverage of the desirable leadership attributes relating to Confucian virtues, communist ideologies, and modern management philophies. The results suggest that, by publicizing and adorning specific leaders in both government and business sectors in the official media, the government reinforces the traditional values that are consistent with communist ideologies, and at the same time, it also introduces Western management values to suit the current needs of the society. The results of our study echo the findings of empirical studies on Chinese values that used data collected using other methods. We therefore encourage future research to use the printed media as a potentially valuable source of data for tracking changes in social phenomena in a society over time.  相似文献

企业是市场经济活动的主体,应该具有其主体属性,并且正是其主体属性决定它的主体地位和作用,并形成主体性产权。但是,学术界缺乏对这个问题的研究,主要是因为受西方经济学传统的限制,要突破这种限制必须把经济学与管理学结合起来进行研究,以构建企业主体性产权理论。企业主体性产权是其相关属性产权与自主属性产权的统一。企业相关属性及其产权是基础和结果,主要说明企业主体性产权的共性;企业自主属性及其产权是原动力和境界,主要说明企业主体性产权的个性。它们的互补和统一突出地体现在企业家及其产权上。企业主体性产权的目的是在防止“蛋糕”缩小的同时把“蛋糕”做大,其核心是基于相互关系的约束而进行自主创造的激励,其模型的运行特点是协同一自主创造。企业主体性产权理论的应用,可以保证和促使中国企业循着超越自然历史发展。  相似文献

公允价值的应用现状及其发展建议   总被引:2,自引:0,他引:2  
中国新会计准则在诸多方面实现了突破,其中公允价值计量属性的运用可谓是最为引人注目的方面。公允价值计量属性的运用,是我国会计准则在国际趋同中迈出的实质性步伐,也标志着我国市场经济日趋成熟。但我国对公允价值的应用与国际相比还有一定差距,现有规定在实施中也面临一些困难,为进一步推行公允价值计量属性在会计准则中的应用,还应在政策制定、会计监管、评估市场、市场环境的完善和会计人员素质等方面做出一系列的努力。  相似文献

This study investigates the interplay between terrorism and finance, focusing on the stock return volatility of American firms targeted by terrorist attacks. We find terrorism risk is an important factor in explaining the volatility of stock returns, which should be taken into account when modelling volatility. Using a volatility event-study approach and a new bootstrapping technique, we find volatility increases on the day of the attack and remain significant for at least fifteen days following the day of the attack. Cross-sectional analysis of the abnormal volatility indicates that the impact of terrorist attacks differs according to the country characteristics in which the incident occurred. We find that firms operating in wealthier, or more democratic countries, face greater volatility in stock returns relative to firms operating in developing countries. Firm exposure varies with the nature of country location, with country wealth and level of democracy playing an important role in explaining the likelihood of a terrorist attack. Our results show that despite significant terrorist events this past decade, stock markets in developed countries have not taken terrorist risk into sufficient consideration.  相似文献

The use of seafood ecolabels is expanding in the world marketplace, but so are labels indicating other product attributes, such as country of origin and wild vs. farmed. The interactive effects of these labels and attributes in evaluating consumers’ preferences for ecolabeled seafood are relatively unexplored. In this paper we investigate (1) the direct and interactive effects of seafood ecolabels with other common fish labels, and (2) how consumers’ perceptions about the state of marine stocks and the valuation of ecolabels may be affected by different information. We find moderate interactive effects between ecolabels and country of origin labels, whereas the valuation for seafood ecolabels is fairly high. In terms of information, we find that consumers’ perceptions about fish stock levels changed (negatively) after receiving information on declining stock levels, and more sensationalized information led to increased change. However, valuation for a seafood ecolabel increases only when the information was perceived positively (credible/interesting); whereas exaggerated information (which was also perceived less credible) had insignificant effects on WTP.  相似文献

Customer satisfaction with a service experience is often determined by several critical attributes. Prior studies have suggested that food, physical environment, and employee service impose an important effect on diners' satisfaction with restaurant services. Although much research has looked at the direct effect of these attributes individually, little is known about them when they are considered together. This study investigates the relative importance and combined effects of the determinants of customer satisfaction in China's hospitality industry. The results show that food taste, employee service, and physical environment (in that order) all significantly contribute to diners' satisfaction, and that one attribute may substitute for another attribute in the satisfaction formation process. Generally, humanic attributes (employee service) can effectively substitute for less humanic attributes (physical environment).  相似文献

For the last twenty years, the perception of hedonic attributes has been a problematic matter in consumer research. We argue that the perception of a hedonic product attribute should not be considered as an irreducible holistic experience, but rather as a complex set of sensory experiences, the components of which are identifiable and quantifiable. We provide evidence for this position by proposing a reliable method linking the features of product-related sound stimuli to consumer perception of hedonic attributes. To our knowledge, this study is the first of its kind offering a detailed investigation of consumer perception of everyday sounds (as opposed to music). We discuss managerial and consumer-level implications of the findings and provide an agenda for future research.  相似文献
