    "Acceptance of online vs. traditional travel agencies"
    in: Anatolia: An International Journal of Tourism and Hospitality Research

    Previous research focused primarily on discovering factors affecting either the benefits and service quality of traditional travel agencies or those of online booking facilities. This study tries to broaden the scope by investigating multiple distribution channel options. It considers different concepts covered by the SERVQUAL instrument, the technology acceptance model, the e-service quality approach and price perceptions as potential value drivers for different travel distribution channels. 58 different perceptual and attitudinal criteria were finally used and condensed into eleven value driving dimensions. These evaluative dimensions were applied together with a set of personal characteristics to discriminate between five different traveller segments defined a priori by their past booking behaviour. Overall, so-called store characteristics seem to dominate the explanation of differences in channel preferences. More favourable price perceptions are attributed to online agencies which is one of the outstanding perspectives of the strongest discriminant function described as ‘online euphorism-scepticism’.

    "A Comparative Study of Information Needs of City Travelers in Europe"
    in: Journal of Information Technology & Tourism

    This article focuses on understanding users' interests in European cities based on log file analysis of keywords entered by users on www.visiteuropeancities.info. It applies various text analysis steps in order to extract significant patterns from the queries made by the users. Multidimensional scaling (MDS) is used for constructing a map of similarities based on the unaided responses gained from the users' information requests. Multiple regression analysis between the most frequently used terms entered by the users and the geometrical representation generated by the MDS provides additional insights in the semantics defining competitive differences between 32 city break destinations in Europe. Findings comprise information on cities that can be considered as kindred in regard to the information demanded by the users of the Web portal. As it becomes clear in which areas cities are perceived as similar, this findings can be used by city (tourism) managers in order to revise their communication plan regarding their own city if desired.

    "A comparison of pre-visit beliefs and projected visual images of destinations"
    in: Tourism Management Perspectives

    Destination image is one of the main decision factors for tourists' destination choice. The aim of this study is to compare the perception of consumers' destination image and the actual projected image of DMOs. Two studies
    are conducted to reach this aim. The first study was an online survey regarding the destination image of selected US cities from the consumer side. The second one was a qualitative study to investigate the visual representation of the destination image of the same cities from the supply side by analyzing their official destination websites. Although the results show an overall match between the two studies, weather conditions, natural views, and shopping were the mismatched topics. The results of this study suggests how the DMOs official communication might benefit from a monitoring/understanding of their perceived image by prospective travelers in order to match tourists' expectations, and/or better place their images.

    "A complex system perspective on the emergence and spread of infectious diseases: Integrating economic and ecological aspects"
    in: Ecological economics

    The emergence and spread of infectious diseases reflect the interaction of ecological and economic factors within an adaptive complex system. We review studies that address the role of economic factors in the emergence/spread of infectious diseases and identify three broad themes. First, the process of macro-economic growth leads to environmental encroaching, which is related to the emergence of infectious diseases. Second, there are mutually reinforcing processes associated with the emergence/spread of infectious diseases. For example, diseases can cause significant economic damages, which in turn may create the conditions for further spread. In addition, the existence of a mutually reinforcing relationship between global trade and macroeconomic growth amplifies the emergence/spread of infectious diseases. Third, microeconomic approaches to infectious disease point to the adaptivity of human behaviour, which simultaneously shapes the course of epidemics and responds to it. Most of the applied research has focused on the first two aspects, and to a lesser extent on the third aspect. In this respect, there is a lack of empirical research aimed at characterising the behavioural component following a disease outbreak. Future research should seek to fill this gap and develop hierarchical econometric models capable of integrating both macro and micro-economic processes into disease ecology.

    "A Conceptual Model for Quality Dimensions for B2C Recommender Systems - Proceedings of the 14th European Conference on Information Systems (ECIS)"

    During the last ten years numerous research instruments emerged for evaluating the service quality of Web-based information systems. B2C recommender systems are information systems that support users in selecting information, products, or services improving their decision making process. Unfortunately, the majority of these instruments do not acknowledge the full range of recommendation functionalities like personalization, registration, security or satisfaction with the proposals given by recommender systems. Therefore, this study focused on the recently published E-S-QUAL scale developed by Parasuraman et al. (2005). A qualitative item generating procedure was used to extend the conceptualization appropriate for recommender systems. This instrument was tested among 15 different B2C recommenders. The empirical data were used to examine the conceptual stability of the extended measurement model about recommender service quality (rSQ). The following six dimensions were successfully identified: efficiency, information quality, personalization, reliability, security, and usability. Efficiency and personalization turned out to be the most dominant influencing factors on web recommender satisfaction.

    "A Context-Dependent Supervised Learning Approach to Sentiment Detection in Large Textual Databases"
    in: Journal of Information and Data Management

    Sentiment detection automatically identifies emotions in textual data. The increasing amount of emotive documents available in corporate databases and on the World Wide Web calls for automated methods to process this important source of knowledge. Sentiment detection draws attention from researchers and practitioners alike - to enrich business intelligence applications, for example, or to measure the impact of customer reviews on purchasing decisions. Most sentiment detection approaches do not consider language ambiguity, despite the fact that one and the same sentiment term might differ in polarity depending on the context, in which a statement is made. To address this shortcoming, this paper introduces a novel method that uses Naive Bayes to identify ambiguous terms. A contextualized sentiment lexicon stores the polarity of these terms, together with a set of co-occurring context terms. A formal evaluation of the assigned polarities confirms that considering the usage context of ambiguous terms improves the accuracy of high-throughput sentiment detection methods. Such methods are a prerequisite for using sentiment as a metadata element in storage and distributed file-level intelligence applications, as well as in enterprise portals that provide a semantic repository of an organization's information assets.

    "A Convenience Yield Approximation Model for Mean-Reverting Commodities"
    in: Journal of Futures Markets

    Standard option-based approximations for convenience yields make use of the assumption that commodity spot prices follow a geometric Brownian motion. While there is some empirical support for this assumption, prices of a wide variety of (agricultural) commodities mean revert. Using a mean-reverting spot price process we derive a novel convenience yield approximation analytically. It corresponds to the difference between the present values of two floating-strike Asian options written on the spot and the futures prices, respectively. Using natural gas spot and futures price data from four different trading locations, we compare convenience yield estimates derived from existing approximations to those of our new measure. We find that convenience yield estimates vary substantially across approximation methods and that differences can be attributed to the cost of carry and the moneyness of the options. © 2014 Wiley Periodicals, Inc.
