- Abstract
Der behandelte Forschungsgegenstand der Arbeit sind die endogenen und exogenen Ein-flussgrößen auf den Endpreis bei online Auktionen, bei starker Homogenität der Aukti-onsobjekte. Als Forschungsobjekt dient der iPod touch 8gb, da es von diesem Produkt zu dem beobachteten Zeitpunkt ein ausreichendes Angebot auf dem Portal eBay.de gab. Die Daten aller entsprechenden Auktionen wurden dann über einen Zeitraum von 15 Tagen beobachtet und aufgezeichnet. Danach wurden die Daten analysiert und die Ergebnisse waren teilweise doch überraschend. Signifikante Werte gab es für die Wochentage, daraus kann man schließen, dass an Wo-chenenden niedrigere Auktionsendpreise erzielt werden als während der Woche. Auch die Tageszeit zeigt einen ausschlaggebenden Einfluss auf den Endpreis der Auktionen; so wird bei Auktionen in den frühen Abendstunden ein niedrigerer Auktionsendpreis erzielt, als zu anderen Zeitpunkten. Der Zustand eines Artikels hat auch einen signifikanten Wert erzielt, demnach erzielen neue Geräte einen höheren Endpreis als bereits gebrauchte aber neuwertige Geräte. Einen entscheidenden Einfluss hatte auch die Variable konkurrierende Auktionen innerhalb von drei Stunden, demnach erzielten Auktionen mit einer hohen An-zahl dieser Variable deutlich niedrigere Preise. Andere Variablen hingegen vielen nicht signifikant aus. So war es zum Beispiel überra-schend, dass die Variablen Garantie und Rechnung vollkommen uninteressant erscheinen. Demnach legen die Käufer keinen Wert darauf zu wissen, wo das Produkt herkommt und nehmen scheinbar gerne in Kauf, dass es sich eventuell um gestohlene Produkte handeln könnte. Auch die Anbieterreputation hatte keinerlei Einfluss auf den Endpreis, allerdings kann dies daher kommen, dass die Mehrheit der Bewertungen sehr positiv war., The research concentrates on exogenous and endogenous determinants that may occur in the end price of online auctions, where the objects of these auctions have to be highly homogenous. The object of research is the iPod touch 8 GB. This product was chosen because there were enough offers on the German portal eBay.de within the observed period of time. For 15 days all data of the concerned auctions have been collected and then analyzed. Some of the results gained were quite surprising. Significant values could be found for the variable day of the week. In more detail it means that lower prices are achieved on weekends compared to days during the week. The time of the day shows an influence as well; so it can be said that in the early evening a higher end price can be obtained than on other time periods on a day. Significant results could also be seen for the condition. This means that the newer a product is, the higher the end price will be. Moreover the variable competing auctions within three hours showed significant values: the more competing auctions, the less the end price of an auction. So it was surprising that variables like guarantee or check had no affect at the price at all. It can be speculated that the buyer does not want to know where the product comes from and accepts that it might be a stolen one. The reputation of the seller had no effect as well, but there is to say that the majority of the ratings were extremely positive.

DECISION making , *TOURISM , *RISK assessment , *TOURIST attitudes , *TOURIST attractions - Abstract
Many studies on risk and destination choice focus on specific destinations or tourist characteristics in an isolated way, resulting in a fragmented nature in research results without a comprehensive understanding. Therefore, an integrated research approach is applied using tourists’ self-assessments of risk and uncertainty in travel decision-making, as well as key characteristics of destinations at hypothetical and realistic stages of the destination choice process. The study uses data collected from a survey on German tourists’ destination choice behavior. The results show that high educational levels and high travel frequencies are distinct characteristics of risk-affine tourists, while higher age groups are more dominant in risk- and uncertainty-averse tourist types. Tourists with varying attitudes toward risk and uncertainty in travel decision-making differ strongly with respect to ideal destinations initially, but choose rather similar destinations when it comes to the final destination choice.

While the relation between terrorism and tourism has been an important topic for tourism research, the questions whether terrorism affects tourism immediately and how long after a terrorism event tourism recovers are, as yet, not clearly answered. The aim of this article is to better understand the magnitude and temporal scale of the impact of terrorism on tourism. To this end, a research model differentiating between short-term and long-term effects of terrorism on tourism is developed and analyzed for the destination Israel using data on tourists from Germany. The results show both short-term and long-term impacts with a time lag between the terrorist event and the beginning of tourism decline of 1 or up to 6 months. An economic influence on the development of tourist arrivals was not detected, but seasonality plays an important role in the relationship between terrorism and tourism. [ABSTRACT FROM AUTHOR]

RISK perception ,TOURISM ,TOURIST attractions ,TOURISTS ,RISK assessment - Abstract
Safety and security are key aspects for the success of tourism in every destination. Rather than objective risks, it is rather the tourist's individual and subjective perception of these risks that mostly influence destination choice and in the long run tourism flows from one country to another. The concept of risk perception has been highly studied in tourism, however the literature remains fragmented resulting in lack of a cohesive and comprehensive framework. It is not yet clear how risk perception as one important determinant of destination choice acts as an influencing factor in the destination choice process. The purpose of this paper is to review and synthesise literature from tourism research and other disciplines on risk and particularly risk perception to develop a framework that offers a better understanding of the role of risk (perception) in the destination choice process. Although travel decision-making and destination choice is a negotiation process between tourist needs and destination offer, most past research has mainly concentrated on the tourist rather than the specific attributes of a destination. The aim is therefore to develop a literature-based framework, including tourist and destination attributes, which is built upon a meta-review of fundamental and recent studies from various disciplines.

56. Investigating Tourists' Destination Choices - An Application of Network Analysis.

- Abstract
A better understanding of the complex destination choice process is highly relevant, both for academia and practice. Tourism research tends to focus either on actually executed or hypothetical destination choices. However, a discrepancy exists between these two types of destination choices which has hardly been investigated. Moreover, past research often studies tourists and their attitudes, needs or perceptions of destinations but not how destinations' attributes affect destination choices. To approach these two research gaps, this study concentrates not only on actual but also on hypothetical destination choices to better understand differences in the evaluation of alternative destinations. This study furthermore examines the role of the destination itself to discover the influence of destination characteristics on destination choices. Therefore, network analysis and set theory are combined in a new research approach which allows to analyse destination choices with varying closeness to reality whilst preserving destination information. The analysis is based on a quantitative survey of German tourists' travel decision-making behaviour. The results reveal changes in destination choices from multidimensional hypothetical choices to unidimensional actual and past choices. Furthermore, only few destinations have a consistent position whilst most destinations are either more relevant for hypothetical or actual destination choices. [ABSTRACT FROM AUTHOR]

AbstractFood consumption represents a substantial share of tourism’s global CO2 emissions. Yet, experimental research on reducing high-emission food choices among tourists is scarce. This study explores how cognitive and behavioural interventions affect the likelihood of choosing vegetarian dishes in hotel restaurants. The authors conducted covert field experiments using theory-informed menu designs to encourage vegetarian food choices. In two hotels, 647 participants received one of four menu conditions: the hotel’s default menu or one of three intervention menus. The intervention menus were designed to test cognitive (using the bandwagon effect) or behavioural interventions (using framing and anchoring biases). The results show that the behavioural interventions outperformed the cognitive intervention in increasing vegetarian orders. When presented with the behavioural intervention, participants had up to 654% (95% CI [2.21, 49.80]) higher odds of choosing vegetarian dishes than the cognitive intervention group. The odds increased to 950% (95% CI [1.26, 27.35]) when the participants were presented with a framing and anchoring-based behavioural intervention. The results indicate that behavioural interventions are more effective in encouraging pro-environmental food choices in hotel settings than cognitive interventions. This study contributes to the literature on pro-environmental behaviour change, presenting suggestions for further studies and practical, theoretical, and managerial implications.
