Abstract Emotional intelligence, a type of social and personal intelligence, is important in managing interpersonal relationships and interactions, especially in the business sphere. Businesses that involve frequent customer contact and interaction, such as those in the field of tourism, can benefit from the application of multiple intelligences. This study examines how, and to what extent, emotional intelligence can benefit the travel and tourism industry. Seven tour operators were interviewed to assess their attitudes, opinions and observations about emotional intelligence and its application to the relationship between tourists and residents of a community. Results showed that all tour operators, to a certain degree, utilized emotional intelligence to offer more personalized travel solutions for tourists. It was found that understanding the cultural values and social etiquette particular to each travel destination was essential for healthy tourist-resident relations. 相似文献

TAX BASIS AND NONLINEARITY IN CASH STREAM VALUATION 总被引:2,自引:0,他引:2
The value of a future cash stream is often taken to be its net present value with respect to some term structure. This means that a linear formula is used in which each future payment is discounted by a factor deemed appropriate for the date on which the payment will be made. In a money market with taxes and shorting costs, however, there is no theoretical support for the existence of a universal term structure for this purpose. What is worse, reliance on linear formulas can be seriously inaccurate relative to true worth and can lead to paradoxes of disequilibrium. A consistent no-arbitrage theory of valuation in such a market requires instead that taxed and untaxed investors be grouped in separate classes with different valuation operators. Such operators are linear to scale but nonlinear with respect to addition. Here it is established that although these valuation operators provide general bounds applicable across an entire class, individual investors within a tax class can have more special operators because of the influence of existing holdings. These customized valuation operators have the feature of not even being linear to scale. In consequence of this nonlinearity, investors from the same or different tax classes can undertake advantageous trades even when the market is in a no-arbitrage state, but such trade opportunities are limited. Some degree of activity in financial markets can thereby be understood without appeal to differences in utility functions or temporary disequilibrium due to random disturbances. 相似文献

混合所有制是指不同所有制产权间的交融混合.混合所有制有宏观与微观两个层次,前者反映不同所有制经济的共同存在,后者指企业中公私不同产权间的相互融合.推进混合所有制的发展,需要解除“国资流失”、“羊入虎口”等多种疑虑,需要让企业人事制度改革,包括董事长与总经理职权关系的厘清、国资代表权力的落实、奖惩与内外监管制度完善等在内的企业法人治理结构的完善. 相似文献

使用简单遗传算法(SGA)求解线性方程组时,由于易发生"早熟"现象,简单遗传算法求出的数值解误差很大甚至会失真。针对此问题,本文提出了一种改进的遗传算法(IGA),并设计了选择算子,交叉算子和变异算子。为了提高简单遗传算法抗"早熟"的能力,采用遗传算子结合惩罚函数,最佳个体保留以及种群迁移等措施。最后以核磁共振测井数学模型线性化后的大型病态线性方程组为例,对算法进行了测试。实验结果表明:同简单遗传算法相比较,IGA在一定程度上提高了数值解的精度。 相似文献

This article presents an artificial intelligence-based solution to the problem of product line optimization. More specifically, we apply a new hybrid particle swarm optimization (PSO) approach to design an optimal industrial product line. PSO is a biologically-inspired optimization framework derived from natural intelligence that exploits simple analogues of collective behavior found in nature, such as bird flocking and fish schooling. All existing product line optimization algorithms in the literature have been so far applied to consumer markets and product attributes that range across some discrete values. Our hybrid PSO algorithm searches for an optimal product line in a large design space which consists of both discrete and continuous design variables. The incorporation of a mutation operator to the standard PSO algorithm significantly improves its performance and enables our mechanism to outperform the state of the art Genetic Algorithm in a simulated study with artificial datasets pertaining to industrial cranes. The proposed approach deals with the problem of handling variables that can take any value from a continuous range and utilizes design variables associated with both product attributes and value-added services. The application of the proposed artificial intelligence framework yields important implications for strategic customer relationship and production management in business-to-business markets. 相似文献
