Assessment of passenger benefits brought about by international airport projects

This study sets forth a method to calculate the passenger benefits of an international airport project and assesses the passenger benefits brought about by two international airport projects.An international airport project mainly increases the number of flights and the possibility of determining convenient timetables. It does not significantly decrease the flight time of international travel. Thus, the user benefits brought about by an international airport project cannot be expressed by the conventional concept of ‘traveling time’, which is the term generally used.In this study, the ‘Expected Value of Traveling Time’ and ‘Expected Value of Generalized Cost’ are presented as indexes to evaluate improvements in convenience brought about by international airport projects. The passenger benefits of two airport projects in Japan are measured by consumer surplus calculated from the demand function using these indexes.These indexes are accurately calculated taking into consideration factors such as scheduling connections between domestic and international transport, and so enable a grasp not only of reductions in flight time, but also of passenger benefits resulting from international airport projects, such as increases in the number of flights and reductions in the time required to make transfers during domestic travel.     

Modeling and optimization of a container drayage problem with resource constraints

This paper investigates the problem faced by firms that transport containers by truck in an environment with resource constraints. The considered area is export-dominant. As a result, there are three types of container movements as inbound full, outbound full, and inbound empty movements. Both the time windows at the terminal and at the customers’ places and the operation times are considered. Empty containers are also regarded as separate transportation resources besides trucks. The total operating time including waiting time of all the trucks in operation is minimized. The problem is first formulated as a directed graph and then mathematically modeled based on the graph. It falls into a multiple traveling salesman problem with time windows (m-TSPTW) with resource constraints. An algorithm based on reactive tabu search (RTS) is developed to solve the problem. A number of randomly generated examples indicate that the algorithm can be applied to the real world.

旅游保险发展与旅游收入增长的相关性分析——以海南省为例

运用spss和eviews统计软件,通过建立计量经济模型对海南省2003～2010年的保险业、旅游业相关经济数据进行回归分析,结果显示,海南省旅游保险发展与旅游收入增长之间存在显著的正相关关系。基于此,提出综合运用政府和市场两方面力量,启动旅游业与保险业双方的合力,建立"旅保合作"的工作机制,建立评价指标体系,对旅游相关企业和保险公司进行评估,构建旅游保险客户数据库等促进旅游保险与旅游业互动发展的策略。     

Traveling with pets: Constraints,negotiation, and learned helplessness

Pets have become increasingly important companions for modern families in daily life and during vacations. Yet traveling with pets involves various uncertainties and constraints that can inhibit tourists' participation. Drawing upon the constraint-negotiation model, this two-step, mixed-methods study examines how these constraints may influence pet owners' travel intentions and how such barriers can be overcome. A qualitative investigation was first conducted based on online user-generated content from 71 Chinese bloggers. Thematic analysis informed the development of an extended constraint-negotiation framework featuring learned helplessness. The extended model was then tested using survey data from 615 Chinese pet owners. Findings suggest that while perceived constraints can inhibit traveling with pets through increased learned helplessness, negotiation can reduce helplessness and encourage pet owners’ tourism participation. Implications and limitations are also discussed.     

浅析旅游环境问题的成因

随着我国经济的发展,旅游业将逐渐成为国民经济的一个新的增长点,甚至成为经济发展的支柱产业。但人们在旅游开发的过程中,却忽视了旅游开发对环境造成的诸多不利影响,如旅游环境保护制度不完善,管理不健全,旅游开发、发展过程中生态意识不强。     

由《推销员之死》与《飞蛾之死》看小角色对生命的态度

小人物的命运也能像大人物那样给人带来心灵的震撼。《推销员之死》中的威利·洛曼是为了谋生和寻找自我价值而面临无尽琐事的许许多多普通人中的一个,因此他命运的悲剧性让人深思。《飞蛾之死》中那个为了能将弱小的生命再多维持一刻作最后挣扎,但最终无法与死神的力量抗衡的飞蛾给读者带来的震撼也同样发人深省。两者虽不为同类,可是他们最终的命运却极为相似,都在百般挣扎中走向生命的终点。但是,显然两个小角色对于生命和死亡的诠释却是截然不同的。     

保定地区旅游经济发展研究

本文以《2006河北省国内旅游抽样调查报告》的数据为基础,分析了保定旅游经济发展中存在的的问题,并寻求问题的根源,最后提出保定地区旅游经济发展的对策,主要有:①利用多种手段宣传保定旅游形象;②实现京津保无障碍旅游,加强和京津冀等地区旅游企业的合作;③利用各种方法,增加景点对游客的吸引力;④打造精品旅游路线;⑤优化旅游发展环境的同时,加强旅游商品的开发。     

旅游强县向旅游城市跨越的战略构想——以星子县为例

基于星子县旅游业发展的现状,九江市政府提出要使"星子旅游业由景区建设向旅游城市跨越".这是旅游自身发展规律的内在要求,是地方经济社会发展的现实需要.星子县自然山水与文化元素变相辉映,大规模高品味旅游资源集聚,旅游市场基础好,又处于庐山、鄱阳湖两大旅游区的中心,区位优势十分明显,在江西省努力构建环鄱阳湖生态经济区的政策背景下,星子县具备由旅游强县向旅游城市跨越的可能性.在此基础上,我们针对星子县的实际,提出了实现这一跨越构想的战略对策.
