基于组合权重TOPSIS的超限货物运输方案评价

超限货物运输方案是铁路安全运输超限货物的重要前提和保障。为实现超限货物运输方案的优选,提出一种基于组合权重和TOPSIS法的铁路超限货物运输方案评价模型。从装载加固方案、线路条件、运输组织复杂程度和运输费用4个方面分析超限货物运输方案的影响因素,确定方案评价指标,构建综合评价指标体系。运用博弈论原理计算方案评价指标的组合权重,其中主观权重由G1法确定,客观权重由熵权法确定。运用TOPSIS法对运输方案进行评价,构建基于组合权重和TOPSIS法的超限货物运输方案的综合评价模型。最后给出超限货物运输实例,运用所构建的评价模型对各运输方案进行评价。结果表明,建立的方案评价模型能够科学、合理地对超限货物运输方案进行比选。

The effect of the authenticity of the Catholic pilgrimage site on spiritual well-being and quality of life of pilgrims

With the growing interest in spirituality, there has been a corresponding rise in the number of pilgrimages. Modern pilgrims embark on pilgrimages not only for religious purposes but also for their own mental peace and health. To enhance our understanding of this trend we conducted an empirical survey of pilgrims visiting Saenamteo Catholic Martyrs' Shrine, a representative martyrdom site in Korea located on the Seoul Catholic Pilgrimage Route, the first Vatican-designated international pilgrimage site in Asia. The analysis showed that the authenticity of the pilgrimage site impacts both the religious and the existential aspects of spiritual well-being. However, while the existential aspect of spiritual well-being impacted on quality of life, the religious well-being was insignificant. These results indicate that modern pilgrims feel that their happiness and health, rather than their religion directly affects their quality of life.

Out of sight,out of cancellation: The impact of psychological distance on the cancellation behavior of tourists

Travel products such as package tours, Airtels, hotel rooms, and airline seats lose their value unless they are sold by a certain date. Therefore, predicting customer behavior allows travel companies to maximize their profits, minimize their loss of revenue by balancing supply and demand (e.g., determining an overbooking level), and wisely respond to pressures from the government and customer groups to lessen cancellation penalties. For this reason, it is important to investigate what cause people to cancel their travel plans after reservations have been made. Based on construal level theory (CLT), this study tries to identify the reasons for the cancellation behavior of customers in accordance with different types of psychological distance between travelers and their travel or reservation behavior. Moreover, it examines the moderating role of tourists’ dependence on a travel agency in these relationships for predicting tourist cancellation patterns in a more specific manner.     

Co-evolution of the strategic reorientation of port actors: insights from the Port of Rotterdam and the Port of Barcelona

This paper explores changes in the strategic orientation of port authorities and terminal operators towards the hinterland network in the Ports of Rotterdam and Barcelona. Port authorities and terminal operators are economically, institutionally and geographically related organizations. The argument here is that such organizations experience a mutually influential and interactive effect in their strategy over time. The research explores the evolution of the market, institutional and governance forces behind these organizations’ strategic orientation, while acknowledging their interdependence and interrelationship. To that end, it builds a conceptual framework analysing these organizations’ strategies in different points in time. It draws upon firms and port theories to design a co-evolutionary framework, which is later refined with insights gained from an empirical study of the port context.     

A model of traveller acceptance of mobile technology

With the growing popularity of mobile technology, mobile communications are becoming an important channel for tourism organisations. This study builds upon a conceptual framework that explains the factors influencing tourist acceptance of mobile devices. To represent the uniqueness of mobile technology acceptance based on an extensive literature review on user technology acceptance, this study proposes two external variables (technology experience and trip experience) and two influential determinants (perceived usefulness and perceived ease of use). These factors together determine user attitudes towards using mobile devices and, consequently, influence user intention and willingness to adopt mobile devices in the tourism context. The results of a confirmatory factor analysis and structural equation modelling showed that trip experience and technology experience positively influenced perceived performance and perceived ease of use, and the factors positively related to travellers' attitudes towards using mobile devices and intention to use them within the tourism context.

Determination of derived importance of a tourism destination: A comparison of indirect methods

Two types of attribute importance, stated and derived, have been studied in marketing and tourism studies using Importance-Performance Analysis (IPA). Derived importance is thought to have an advantage over stated importance in reducing survey fatigue and social desirability biases, and thus is more predictable to an outcome variable. Derived importance is also used in a Relevance-Determinance Analysis to determine higher-impact core attributes or in an Importance Grid Analysis to explore the asymmetric relationship between attributes and overall satisfaction. Since derived importance is usually estimated through statistical methods, it is necessary to determine which method is the most appropriate. However, few studies have examined the appropriateness of indirect methods. To fill this research void, this paper judges the appropriateness of three statistical methods (i.e. multiple regression, partial correlation, and simple regression) based on data collected from Savannah, GA, using a new approach by which results of derived importance were compared against diagnostic attributes in the “keep up the good work” quadrant of IPA. Diagnostic attributes are attributes with higher stated importance and higher predictability of an outcome variable. Results show that urban forests and cultural heritage are such attributes, and simple regression is the best to infer attribute importance.
