体育旅游产品消费的文化背景 总被引:9,自引:1,他引:9
人们的消费具有社会性,因而具有很强的时代性。在国内外兴起并迅速发展的体育旅游产品是时代的产物,它是休闲时代人们消费的主体产品,是体验经济时代旅游产品的升级换代产品。人们通过消费体育旅游产品,不但能休闲、娱乐、健身、交际,还能发展自己、完善自己、实现自我价值,从而迎合了知识经济时代人们消费的价值观。我国有极其丰富优越的体育旅游资源,关注并开发体育旅游市场是我国旅游业可持续发展的重要战略。 相似文献

The aim of this study is to develop a material selection framework structured around a knowledge-based system (KBS). Specifically, a hybrid data mining technique is employed to extract knowledge from large datasets using cluster analysis techniques; the mined knowledge then serves as the inference logic within the KBS designed for material selection purposes. Cluster analysis results are used as a basis for the tree-based structure of the KBS where if–then rules are developed based on the general cluster properties; that is, inference logic is structured in a way such that it can predict general sustainability characteristics of the material as well as its exact mechanical, cost and physical properties. To develop the structure of the KBS, the selection structure employs sustainable material indices. Additionally, the proposed material selection model of the KBS is purposefully composed of material sustainability, functionality and cost indices. The constructed knowledge is then demonstrated for selecting automobile structural panels. 相似文献

按照传统的会计处理模式和惯例,无形资产中可以辨认的专利权、商标权已予确认和计量,而对于商誉,国内会计准则规定,只有在企业并购时,才作为一项无形资产确认入账,即只对外购商誉进行确认和计量,而不确认和计量自创商誉.在新的经济形势下,对于自创商誉应该有新的认识,就对自创商誉的确认和计量问题做出一些论述.参5. 相似文献

Recent calls for knowledge-based journalism advocate a new level of formal knowledge in news reporting to meet the professional challenges caused by rapid change in the news industry. Scientifically knowledgeable journalism has the potential to redefine the existing science–media relationship. However, the audience for such journalism is unclear, nor is it known how this new journalism would function within rapidly changing newsroom practices. Implementing knowledge-based journalism requires theory-based propositions to show the actual benefits of improved scientific understanding for news consumers and an understanding, from research into professional cultures, of why new practices in journalism are adopted or abandoned. This paper develops that theoretical basis by examining knowledge-based journalism’s potential and some of the intellectual and institutional barriers to it. 相似文献

This article addresses methodological issues of the human reliability analysis (HRA) in the context of probabilistic safety studies. Several conventional HRA techniques, more often used for the evaluation of the human error probabilities (HEPs), have been classified. A taxonomy of human actions, failure events, and related factors is outlined in order to distinguish action phases, human behavior types and incorrect outputs (errors of omission or commission), error types (slips, lapses, and mistakes), and performance-shaping factors (PSFs) influencing the human performance. A tree is proposed to facilitate the selection of a specific method for the evaluation of human reliability with regard to attributes of the situation analyzed. A software system based on the expert system technology to facilitate and document PSA and HRA is outlined. At the end of the article some research challenges in the domain are discussed. 相似文献
