Commercial aviation’s contribution to climate change is growing, but the global role of private aviation is not well quantified. Here we calculate the sector’s CO2 emissions, using flight tracker data from the ADS-B Exchange platform for the period 2019 to 2023. Flight times for 25,993 private aircraft and 18,655,789 individual flights in 2019-2023...

Firm growth is one of the goals of many entrepreneurs in the tourism sector, and its study is in line with Sustainable Development Goal 9. This SDG refers to decent work and economic growth. Firm growth is associated with a positive performance and a sign of the potential long-term survival of the firm. Though many factors can influence the growth...

Authenticity has been long debated in a panoply of tourism contexts. In events, it has been linked to satisfaction and intention to revisit although the extent to which it is important for all types of attendees remains unclear. The purpose of this study is to investigate perceived authenticity at the world's most iconic beer festival, the Oktoberf...

Recent years have seen vivid debate on decarbonizing aviation. Carbon-neutral flight is characterized by various barriers, however: Key transition technologies are in early stages of technology readiness, their scalability is uncertain, and airlines are not profitable. The replacement of fossil fuels will demand drop-in quota legislation at a globa...

Rural areas are characterized by limited access to public transportation. In the absence of alternatives, many older people continue to drive private cars. This imposes risks on society and older people, as traffic risks increase with declining mental and physical health. As opportunities to remain mobile have key relevance for quality of life, thi...

Smart Tourism for the Industry 4.0 and post Covid-19 challenge needs explainable AI Algorithms adapted for the Volatility, Uncertainty, Complexity and Ambiguity (VUCA) World with smart (physical components, algorithms, and IoT/mobile connectivity) elements. This paper shows how boosted generalized additives models (GAM) and random forest can be use...

Much evidence suggests that the wealthiest individuals contribute disproportionally to climate change. Here we study the implications of a continued growth in the number of millionaires for emissions, and its impact on the depletion of the remaining carbon budget to limit global warming to 1.5 °C (about 400 Gt CO2). To this end, we present a model...

There is a general consensus that private car ownership is a significant barrier to transport system change, specifically in regard to injuries, space, air pollutants, or greenhouse gas emissions. Observed changes in automobile characteristics also suggest that the system is becoming less sustainable, given trends towards larger cars with greater m...

Traffic safety is high on the agenda of European governments. Yet, countries including Germany maintain policies that are commonly identified as increasing traffic risks, such as speed limits set too high or trends of greater car motorization and mass. To better understand some of the interrelationships of driver characteristics and car segments, t...

The profile of engineers must also include digital technologies in order to be adequately trained for the future. With the help of an active and collaborative learning experience, students’ motivation and involvement could be increased. Originally, interactive workshops were created as a pop-up makerspace and built on constructivism learning theory...

Technology-supported applications have been found to improve cultural heritage tourism experiences. This paper raises the question of whether and how Virtual Reality technology is accepted as a means to communicate cultural heritage. The second iteration of the Unified Theory of Acceptance and Use of Technology (UTAUT 2) is employed to investigate...

Parking fees and fines represent contested issues in cities, as they conflict with vehicle owners' opinion over ‘rights’ to public space. As cities have moved to regulate vehicle density by introducing parking fees, a share of drivers may feel compelled to ‘cheat’, weighing the price of parking fees against the cost of fines, or to simply park ille...

Shipping is associated with various environmental impacts, such as pollutants discharged to air and sea. Much of this pollution appears to be unregulated, and global emissions from shipping are expected to more than triple between 2020 and 2050. This paper reviews global, national, regional and port-level legislative approaches that have been imple...

Teaching sustainability presents challenges due to the inherent complexity and required behavioral change. A special pedagogical approach is needed. In this paper, we focus on the research question how students' awareness of sustainability issues can be improved significantly in a brief workshop. The presented workshop let the students autonomously...

Weather can be a major concern for travelers when choosing a destination, preparing their trip and during their stay. Existing publications focus on explaining the role of weather based on one, or at most, a few parameters and usually for one season. This paper proposes a new approach covering all four seasons by connecting daily data from meteorol...

The COVID-19 pandemic has led to an unprecedented decline in global air transport and associated reduction in CO2 emissions. The International Civil Aviation Organization (ICAO) reacted by weakening its own CO2-offsetting rules. Here we investigate whether the pandemic can be an opportunity to bring the sector on a reliable low-carbon trajectory, w...

In the first five months of 2020 industrial production in the US fell 15% due to the Covid-19 shut down. At the sametime the S&P500 stock market index first dropped by 30% and then recovered to almost pre-crisis levels. This seemspuzzling as the most severe economic recession in nearly a century unfolds. However, central banks have supportedfinanci...

Prior to the COVID-19 crisis, global air transport demand was expected to triple between 2020 and 2050. The pandemic, which reduced global air travel significantly, provides an opportunity to discuss the scale, distribution and growth of aviation until 2018, also with a view to consider the climate change implications of a return to volume growth....

The author proposes a new approach for bridge crack detection by a 360° camera on top of a drone. Traditionally, bridge inspection is performed manually and although the use of drones has been implemented before, researchers used standard high definition cameras underneath the drone. To make the approach comparable to the conventional approach, two...

Purpose This paper aims to investigate participants’ motivations and perceptions of a field trip. Specifically, this paper examines if and how students’ perceptions change with time and it explores the main factors for ensuring success in an experiential learning tourism program. Design/methodology/approach The study gathered and compared data col...

Authenticity within tourism has received a great level of attention from scholars. In the particular context of events, authenticity has been linked to satisfaction and intention to revisit, although empirical proof of such link remains scarce. The purpose of this study is to address this issue by investigating the perceptions of authenticity of fe...

‘Flight shame’ describes an unease about the climate implications of air travel, and bears evidence of a change in social norms that have so far associated flying with social status. This paper discusses whether Fridays for Future demonstrations and ensuing flight shame have influenced social norms regarding the desirability of air travel, and whet...

This paper presents a didactical concept to introduce university students to new digital technologies like 3D printing, robotics and virtual reality. The concept is based on problem-based learning and set up in a constructivist learning environment. In order to test the influence of different constructivist dimensions on the perceived improvement o...

Often, new technologies like additive manu- facturing and digital technologies are taught at university pri- marily theoretically with the help of displaying images and short videos. Students regularly miss the practical application of digital technologies as well as the experience and the possibility to develop creative new ideas with these techno...

This paper presents a didactical concept to introduce students from various disciplines to digital technology and specifically to Virtual Reality technology. The concept is embedded into a constructivist learning environment to increase active involvement, self-directed learning and eventually motivation of students. Furthermore, it is based on a h...

Based on the present value model for stock prices, we utilise a pooled mean group estimator for panel ARDL cointegration to estimate the long-run relationship between G7 stock prices and macroeconomic variables over the last 40 years. We find a positive long-run relation between stock prices, industrial production and consumer prices as well as a n...

: Research has dealt extensively with different aspects of climate change and winter tourism such as the impact on ski resorts and ski lift operators, adaptation strategies, governance at destinations and reactions of winter sports guests to changing snow conditions. This paper goes deeper into the question of destination choice and examines the ro...

Long haul trips are an increasing sector of the travel industry. One among several drivers especially in the winter season are cruise trips in warm destinations. This article shows the extreme contributions of such trips to the carbon footprint of the tourism sector.

Active mode (walking, bicycling, and their variants) users are exposed to various negative externalities from motor vehicle traffic, including injury risks, noise, and air pollutants. This directly harms the users of these modes and discourages their use, creating a self-reinforcing cycle of less active travel, more motorized travel, and more harmf...

Company cars have received considerable attention because of their partial tax-exemption and the changes in travel behaviour they stimulate, including car model choices, distances driven, and car ownership patterns. This paper is the first to present evidence on actual transport behaviour change, based on mobility and fuel diaries, and comparing a...

This paper considers how the strength and nature of the relation between the equity and bond yield varies with the level of the real bond yield. We demonstrate that at low levels of the real bond yield, the correlation between the equity and bond yields turns negative. This arises as the lower bond yield implies heightened macroeconomic risk (e.g....

Within the framework of rational bubbles the authors examine the existence of temporary bubbles in the German equity market between 1973 and 2014. Moreover, the bubbles are distinguished between rational price bubbles and intrinsic bubbles that arise from overreaction to fundamentals. Over the last 40 years, four prolonged periods are identified wi...

Using smooth transition regression model analysis, we examine the non-linear predictability of Japanese and US stock market returns by a set of macroeconomic variables between 1981 and 2012. The theoretical basis for investigating non-linear behavior in stock returns can be based on the interaction between noise traders and arbitrageurs or behavior...

Within the framework of a standard discounted value model, we examine whether a number of macroeconomic variables influence stock prices in the US and Japan. A cointegration analysis is applied in order to model the long-term relationship between industrial production, the consumer price index, money supply, long-term interest rates and stock price...
