The Tourist Bubble and the Europeanisation of Holiday Travel

This account explores certain aspects of the developments in international, interEuropean holiday travel as a part of the phenomena characterised as modernity and Europeanisation. The focus is on the idea of 'travelling parochialism', i.e. whether large proportions of contemporary international holidaymakers and other travellers on their tours within Europe adopt some kind of furtherance of a home-like culture. The main point of departure is the idea of the 'tourist bubble' understood here as a territorial and functional differentiation and as an expectation of holidaymakers going abroad. The concept of 'travel ecumene' is introduced to examine implications for travellers of the development of a western European travel system. Moreover, the study analyses the extent to which the notion of the tourist bubble is still beneficial in comprehending significant aspects of inter-European holiday travel in relation to current discourses of internationalisation, Europeanisation and cosmopolitanism. The paper also discusses advances of cosmopolitan predilections and aspirations and their possible influences on contemporary international European tourism.     

Reliable evacuation planning via demand inflation and supply deflation

This paper presents an evacuation route planning model that both accounts for demand uncertainty (i.e. the number of evacuees) as well as capacity uncertainty (i.e. the road capacities). To ensure reliability, the model plans for more evacuees (i.e. demand inflation) and less road capacity (i.e. supply deflation). A major contribution is that we provide a framework to determine the amount of demand inflation/supply deflation necessary to ensure a user-specified reliability level. The model is shown to be a natural generalization of previously proposed evacuation models. A small numerical case study reveals the key characteristics of the model.     

Earnings Volatility,Post–Earnings Announcement Drift,and Trading Frictions

We find that lower ex ante earnings volatility leads to higher Post–Earnings Announcement Drift (PEAD). PEAD is a function of both the magnitude of an earnings surprise and its persistence. While prior research has largely investigated market reactions to the magnitude of the earnings surprise, in this study we show that the persistence of the earnings surprise is equally important. A unique feature of the anomalous PEAD returns documented here concerns the association between abnormal returns and trading frictions. Besides demonstrating that firms with lower earnings volatility have higher abnormal returns, we also find that lower earnings volatility firms have lower trading frictions. Taken together, these findings imply that higher abnormal returns are associated with lower trading frictions. We exploit this implication to empirically demonstrate that PEAD returns due to earnings volatility are not concentrated in the firms with the largest trading frictions, which is in contrast to the findings in prior anomaly studies.     

Vector network equilibrium problems with capacity constraints of arcs

In this paper, we study a (weak) vector equilibrium principle with capacity constraints of arcs and common arcs in some different paths. We obtain some necessary and sufficient conditions for a (weak) vector minimum cost flow. By virtue of a (weak) Δ-equilibrium principle, we also derive some necessary and sufficient conditions for a weak vector equilibrium flow.     

Does one model fit all? Exploring factors influencing the use of blogs,social networks,and wikis in the enterprise

Enterprise social media (ESM) have become increasingly widespread, but many intranet communities barely survive, miss their initially planned targets, or are even terminated. Research on technology acceptance can be a useful approach to improve adoption rates, but more empirical research needs to be conducted to examine factors driving the adoption of enterprise social media. To address this gap, we develop a model of individual ESM adoption, including technological and individual factors based on findings from collaboration and knowledge-sharing research. Because different ESM tools, such as blogs, social networks, and wikis, can be employed for fundamentally different uses, we explain differences between individual adoptions of the three technologies by identifying their uses and gratifications from the perspective of employees. The model is tested in three parallel studies, one for blogs, social networks, and wikis each, among employees of an international technology company in the pre-implementation phase. We find substantial differences between the factors influencing the intention to adopt the three applications. This provides the basis to employ the applications in a more effective way by considering organizational and employee needs.     

Advanced models of quality function deployment: a literature review

In this paper, a literature review conducted to study the characteristics of advanced models of quality function deployment (QFD) that have appeared in the literature arena is reported. QFD technique emerged in Japan in the 1970s. QFD has been proving to be a powerful tool that can be used for translating the voice of customers into technical languages. Yet from the beginning of this century, researchers began to point out the need to refine, modify and improve the features of QFD technique. In order to fulfil this need, few researchers brought out several advanced models of QFD. While conducting the literature review reported in this paper, six types of such advanced models of QFD were identified in the literature arena and their characteristics were studied. The result of this study revealed that the procedural and computational complexities are least in the case of an advanced model called total quality function deployment (TQFD). TQFD technique replaces the complex computations involved in applying conventional QFD technique with simple ratings. Besides the formation of teams to translate the voice of customers into work instructions ensures the quick reactions to the customers’ desires in the actual field of implementation. In this background, at end of this paper, it is suggested to adopt TQFD for implementation in traditional organizations in which the prevalence of adequate education for adopting complex procedures is found to be least.     

Trends and prospects of ensuring energy resources in Ukraine

The article examines the state of power supply in Ukraine for the period from 2000 to 2010. The trend in the Ukraine GDP energy intensity (at purchasing power parity), compared to other countries of the Commonwealth of Independent States, is analyzed. The key points of demand determination and of alternative ways to satisfy it in Ukraine for the period until 2015 are formulated. A forecast of production and consumption of energy resources was conducted in accordance with the expected socioeconomic development of the country through the development of advanced fuel and energy balances.
