Purpose The purpose of this paper is to explore the applicability of technology acceptance model (TAM) to explain the widespread acceptance and usage of social media (SM) for travel purposes by Indian outbound leisure travellers during their travel cycle. Design/methodology/approach The study has adopted a qualitative approach involving in-depth interviews of 30 respondents, who had taken at least one international vacation in the last 12 months. Content analysis was used to arrive at the conclusion. Findings Findings of the study are used to develop a conceptual model which upholds the validity of the TAM with perceived usefulness (PU) and perceived ease of use (PEU) as determinants of SM usage. The model has been extended to include perceived trust (PT) and social capital (SC) as important constructs to explain the travellers’ use of SM. Disposition readiness (DR) of the user towards SM was found to have an effect on all the four constructs. Originality/value Theoretically, this study suggests a modification to the existing TAM, which shows a unidirectional effect of PU and PEU on attitude. This study suggests that the effect would be bi-directional where the attitude (DR) of the traveller towards SM usage will affect PU and PEU. Furthermore, this study extends the TAM to include PT and SC as important constructs to explain SM usage by travellers. This study provides valuable insights into the hospitality and tourism sector which might help in further segmentation of travellers leading to more customised service offerings.

PurposeAfter each of the COVID-19-induced lockdowns, an unprecedented surge in leisure travel was observed, resulting in tourists flocking to places of tourist interest. This phenomenon was termed revenge travel in popular literature. The purpose of this study is to explore the phenomenon of revenge travel in detail through an academic lens. It examines the psychological and emotional motivations for revenge travel while studying the differences in travel behaviour pre- and post-pandemic.Design/methodology/approachThe study applies an interpretive phenomenological approach to explore post-pandemic travel behaviour. Data were collected via personal in-depth semi-structured interviews. Thematic analysis of the transcripts was conducted to arrive at discussion themes.FindingsDrawing on the established theories, the findings of the study indicate that lockdown fatigue coupled with mortality salience induced individuals towards leisure travel. This in turn led to mood alleviation and compensation for the deprivation undergone.Practical implicationsThe study reveals important insights into post-pandemic preferences of travel destinations (off-beat locations near urban clusters), accommodation options (more travellers choosing home stays and stand-alone properties) and vacation itineraries (a gradual shift towards slow tourism with more focus on immersive experiences). Further, there are indications that hotels may develop “workcations” and “staycations” as a new line of offering.Originality/valueThe study adds to the small body of knowledge on revenge travel. It adopts a phenomenological approach, thereby capturing the “lived experiences” of the participants and providing an in-depth look into the psychological and emotional motivations of revenge travel that have not been explored previously. The study provides insights into the travellers' psychology post a period of withdrawal and restraint.

Since the beginning of the 21st century the architecture of software systems and especially distributed software systems have seen a considerable evolution making them easier to extend, reuse and manage. As a result, software systems have become more reliable and robust. In addition to the higher requirements for their products, software developers have to deal nowadays with more complex architecture. The challenge lies in the fact that software systems are constituted of components that are more and more autonomous and may be deployed with di erent technologies and in far geographic locations. Building such heterogeneous systems gained popularity since the appearance of Microservices which resulted in a higher performance that could be improved further by including asynchronous communication between the constituting services. All these changes though bene cial, may make the extraction of a documenting model of such systems more tricky. On the one hand such systems provide through their exible architecture a lot of advantages. On the other hand, they are more likely to be changed fast and thus make their documentation less reliable and hence di culties for maintenance and extension will increase. Through our thesis we treat this problem by extending an existing approach of model extraction of microservice-based systems from their tracing data in a way that message-based systems can also be supported. We evaluate then our results using statistical metrics such as precision, recall and F1-score in order to make sure that the accuracy of our extracted model will not be decreased compared to the approach we are extending, which is actually the case. Hence, through our approach, we provide a way to extract performance models to document message-based system in a much easier and less error prone way then the manual alternative. Subsequently, further possible future works such as calculating failure estimation and resolving parametric dependencies are presented. i ZusammenfassungSeitdem Beginn des 21, Jahrhundert hat sich die Architektur der Software Systeme insbesondere verteilte Systeme erheblich entwickelt, so dass sie besser erweiterbar, wiederverwendbar und verwaltet sein können. Im Folge dessen, sind Software Systeme zuverlässiger und robuster geworden. Deswegen, zusätzlich zu den höheren Anforderungen für ihre Produkte, müssen sich Software Entwickler heutzutage mit komplexeren Architekturen auseinandersetzen. Die Herausforderung besteht darin, dass Software Systeme Komponenten umfassen, die immer autonomer werden, mit verschiedenen Technologien bereitgestellt werden können und sich in weit entfernten geographischen Positionen be nden. Das Bauen solcher heterogenen Systemen hat mehr an Popularität gewonnen seitdem erscheinen von Microservices, die für eine höhere Leistung gesorgt haben, die wiederum noch besser sein könnte durch das einsetzen asynchroner Kommunikation zwischen den konstituierenden Services. All diese Änderungen, auch wenn vorteilhaft, können die Extraktion eines dokumentierenden Modells solcher S...
