Greening transportation fleets: Insights from a two-stage game theoretic model

The greening of organizational transportation fleets, especially trucks and automobiles, has gained increasing attention by companies in a variety of industrial sectors. The reasons for this concern and attention are due to regulatory and competitive pressures, but also increasing costs of fossil-fuels. Surprisingly the amount of research and modeling for fleet management overall has been rather limited, with the focus on managing green vehicle investments virtually non-existent. In this study we develop a two-stage game theoretic model that helps evaluate, from both policy and organizational perspectives, the implications of greening of transportation fleets. Various parameters are evaluated including factors such as innovations in green vehicle technology, levels of service differences, cost of fuel, adjusting tax policy, regulatory compliance requirements, and adaptation costs. This evaluation provides practical insights into actions that could be considered by regulators and organizations to encourage environmental investments.     

A Study on Flow Experience Structures: Enhancement or Death,Prospects for the Korean Wave

In proposing the concept of flow which focuses on experiencing the sites visited by Korean Wave tourists as induced by drama or movies, the role of involvement level (variables) of Korean Wave tourists in influencing flow construct as they experience the sites of FIT (Film Induced Tourism) was investigated. The involvement level of Korean Wave visitors was found to operate as a mechanism by which challenge, skills, and focused attention on site might be more organized or more actively experienced. This recognizes that there is clearly a need for making the FIT sites exposed much by any mix of various media. The findings of this study showed that challenges and skills influence enjoyment as an output factor of flow. Film site visitors are assumed to participate in the roles of film characters, experiencing the places and the atmosphere. The degree of visitors' reflections of the film optimizes awareness of flow experiences on the site. Therefore it is necessary to provide more detailed experiential programs on the film sites with a wide variety of flow-related contents in the film.     

The spatial and temporal variation in passenger service rate and its impact on train dwell time: A time-series clustering approach using dynamic time warping

This study aims to improve the understanding of the underlying mechanism of passenger boarding and alighting processes, as well as its potential influence on train dwell time and train operation. Empirical data collected from one of busiest metro stations in Seoul, Korea, demonstrates the spatial and temporal variation in the passenger service rate, as a result of interference between boarding, alighting, and standing passengers. This study postulates that the level of interference can be associated with the train car occupancy and the proximity of train door to entry points, as waiting passengers tend to cluster near the platform entries. A unique temporal service rate curve is derived from each door location. We introduce Dynamic Time Warping for similarity assessment and clustering. It revealed four groups of train doors showing distinct shapes of curve from each platform. The first cluster includes the train doors located closest to the platform entry points where the initial service rate is drastically impeded by severe inference among passengers. The level of interference gradually diminishes as the door is located farther away from the entry points, but the overall service rate decreases as well. A passenger service time model is derived to include the cluster variable. To test its significance, the prediction capability of the model is presented with and without the cluster variable. The results of this study may be used to guide waiting passengers along the platform to minimize interference and to avoid serious disruption during passenger service time.     

The constraints of Chinese tourists to visit Korea caused by THAAD using Q-methodology

The recent deployment of the THAAD system to South Korea has resulted in complex and controversial issues, particularly in the political, diplomatic, and economic relations between Korea and China [Perlez, J. (2017, May 31). China woos South Korea’s new leader, but the U.S. left behind a spoiler. The New York Times. Retrieved from https://www.nytimes.com/2017/05/31/world/asia/china-south-korea-xi-jinping-moon-jaein-thaad.html?_r=0]. To minimize its negative impact on international tourism, the underlying psychological mechanisms of Chinese tourists associated with this complex political issue should be determined. As an attempt to resolve the current crisis, this study identified the subjective characteristics of Chinese tourists who cancelled visits to Korea using Q-methodology and classified Chinese tourists’ attitude towards the THAAD issue. Based on respondent’s evaluations on Q-sample statements, four types of Chinese tourists were articulated, namely, patriotism, risk awareness, external dependency, and Lotte sanctions. By delving into tourists’ subjectivity, Q-methodology seems powerful to elicit intrapersonal constraints, which are deeply embedded in an individual’s psychological state. The results showed that the THAAD issue greatly influenced Chinese tourists’ personal values, beliefs, and identities.     

The politics,satisfaction, loyalty,and success of Ph.D. students in hospitality and tourism

The purpose of this study was to explore the roles of organizational politics in educational institutions with regard to graduate students’ satisfaction with supervision and loyalty toward advisors, and thereby success of students in the Ph.D. program, within the hospitality and tourism discipline. The findings demonstrate that satisfaction and loyalty play important roles in doctoral students’ experiences in graduate education. Several implications for students and faculty are discussed.     

Limit to improvement: Myth or reality?: Empirical analysis of historical improvement on three technologies influential in the evolution of civilization

The evolution of civilization appears to have primarily resulted from continuous improvement made possible by technological advances. A group of social evolutionists and economists have identified, among others, energy, transport, as well as information and communication to be the three most influential technologies. On the other hand, a number of eminent scholars have cited several forces, natural, physiological, technological, as well as environmental which can place a limit on on-going improvement.The purpose of this paper is to empirically explore the continuous improvement process as well as the limit placed on these three technologies. Using the framework of both connected and disconnected multiple technology S-curves and X-factor, historical improvement data on these three elements have been analyzed. The results of our analysis indicate that improvement in general has continued without limit mainly due to a series of emerging new technologies. These emerging technologies can be either connected or disconnected from the existing mature technologies. Our preliminary analysis shows that much of the past improvement comes from new technologies that on first serious application appear to be substantially superior from earlier technologies. In addition, enormous continuous improvement, which has accompanied both connected and disconnected new technologies appear to have played the critical role in sustaining the evolution of civilization. The paper discusses a number of policy implications and suggests topics for future research.     

Beliefs of and attitudes toward political advertising: An exploratory investigation

The major goals of this study were to identify voters' belief structures about political advertising, develop a scale to measure beliefs, and examine how the identified beliefs are related to overall attitudes toward political advertising. The reliabilities, factor structure, and validity tests indicate that five belief dimensions—information, veracity, cynicism, money politics, and entertainment—have sound and stable properties. The scale demonstrates that voters assess political advertising at the instrumental level (e.g., information, veracity, and entertainment) as well as the institutional level (e.g., cynicism and money politics). The results showed that not all beliefs predicted overall attitudes. Furthermore, the results indicated that political involvement was a significant factor in influencing both beliefs and attitudes. © 2009 Wiley Periodicals, Inc.     

Relationships among consumer vanity,gender, brand sensitivity,brand consciousness and private self‐consciousness

The purpose of this study was to examine relationships among consumer vanity, gender, brand sensitivity, brand consciousness and private self‐consciousness within a context of social comparison theory. The four dimensions of consumer vanity are concern for and positive view of physical appearance and concern for and positive view of achievement. Participants were 400 college students (284 women; 116 men). Participants above the median in three of the four dimensions of vanity (except vanity achievement view) were more sensitive to and more conscious of brand names. Participants above (vs. below) the median in vanity achievement view scored higher on private self‐consciousness. Women scored higher on brand sensitivity, brand consciousness and private self‐consciousness than men. There was a significant correlation between brand sensitivity and brand consciousness. Results support the notion that consumers’ decisions, especially regarding brand names, may be guided by vanity‐related concerns and views.     

The French commitment to European monetary integration: A review of the two EMS crises (1981–83, 1992–93)

This paper focuses on the process of exchange rate management during the two European Monetary System(EMS) crises, in 1981–83 and 1992–93, and examines the factors which led the French governments to adhere to the EMS. France's strong franc (franc fort) policy is a useful test case for maintaining national commitment to European monetary integration. The origin of the franc fort policy can be traced back to the exchange rate crisis of 1981–83. By actively supporting European institutions and emphasizing the emergence of a strong and united European common currency, France discovered the way to bolster confidence in her economic policy. Beyond this focal point, political justification and economic rationality became mutually reinforcing, configuring French national preference in European monetary integration. The response of the French government to the EMS crisis of 1992–93 was more consistent compared to the response to the 1981–83 crisis, and reflected the accumulation of loyalty to European monetary integration. This loyalty, however, was made neither from purely economic calculation nor out of normative commitment French European monetary policy reflected the interaction between domestic politics and European monetary integration. The French commitment to the franc fort also was based on domestic political bases such as the existence of a core policy group, a centralized policy‐making structure, and an issue linkage between the franc fort and European integration.     

The role of interactivity in e-tailing: Creating value and increasing satisfaction

The purpose of this study is to examine the relationships between three dimensions of interactivity (controllability, synchronicity, and bi-directionality) and consumers’ perceived value composed of utilitarian and hedonic values on e-shopping, finally determining the level of overall satisfaction on using interactivity features in e-tailing service. A total of 451 respondents participated and the usable sample size was 427 after the screening process. The results indicate that bi-directionality is a key interactivity feature for consumers’ hedonic value creation in e-tailing service settings while synchronicity is a key for utilitarian value.
