Abstract
Purpose
This paper aims to present an aerothermodynamic analysis of a new concept of a small hypersonic airplane. Aerodynamics characteristics for different flow conditions encountered during the missions are analyzed. The effects of elevons deflection for pitch control and of the presence of engines on aerodynamic performances are also investigated for different flight conditions. The effects of boundary layer laminar–turbulent transition on aerodynamic heating are studied to preliminarily identify proper materials that can sustain the hypersonic phase.
Design/methodology/approach
Aerodynamic characteristics are predicted by means of the semi-empirical aerodynamic prediction code Missile DATCOM and computational fluid dynamics simulations. Computational fluid dynamics analysis is also performed to investigate aerodynamic heating phenomenon.
Findings
Major discrepancies between the results offered by the two methods have been registered in transonic regime, whereas in subsonic and super-hypersonic conditions, Missile DATCOM confirms to be a suitable tool for preliminary design steps. The results of the analysis show that for the identification of the materials that can sustain the hypersonic phase, the turbulent solution must be taken into account. Carbon fiber reinforced ceramics composite materials seem particularly well suited for the nose, wing and vertical tail leasing edges and control surfaces, while titanium alloys could be used for the rest of the vehicle surface.
Originality/value
This new concept of vehicle is designed both for point-to-point medium range hypersonic transportation and long duration suborbital space tourism missions, by integrating available technologies developed for aeronautical and space systems.

Abstract
Purpose
The aim of this manuscript is to study the current scientific literature on food marketing and religion, by giving an overview of current knowledge and the possible future research opportunities once found the gaps.
Design/methodology/approach
This a classic literature review carried on by considering marketing, consumer behaviour and management journals as well as religion-focused ones.
Findings
Current literature highlights how faith impacts on food marketing and religious consumers choices (and not only). Most of the papers focus on Islam. Considering the globalised economy, the authors’ findings highlight also the relevance of religious certifications for less/not religious people, because of certified food is considered safe and healthy.
Originality/value
The paper joins and reviews two research fields whose connection is growing, so it is relevant to know the current status of scientific literature, which is updated compared to recent literature.

Abstract
Purpose
Palm oil is widely used in the food industry; however, there are two main controversies connected to its use, namely, its nutritional value and the environmental consequences deriving from its crop. In Italy, the use of palm oil has recently been criticized, insomuch that some important bakery companies decided to substitute it, creating a real food marketing case. Through a focus on biscuits, this study is aimed at profiling consumers with regard to palm oil issue to better comprehend if the presence of this ingredient truly influences their food purchases and if they care about the nutritional and environmental aspects, highlighting the impact of the Covid-19 pandemic on consumers' consumption.
Design/methodology/approach
A questionnaire was administered to 243 subjects in Italy, in order to apply a cluster analysis.
Findings
The findings show the presence of three main kinds of consumers: (1) compromise finders (sensitive to cost savings but trying to privilege palm-oil free food), (2) brand-loyal consumers (palm oil does not influence their preferences) and (3) healthsensitives (the presence of palm oil profoundly affects their choices), who represent the majority of our sample. The results and implications are discussed.
Originality/value
Research on palm oil is essentially focused on chemistry, natural sciences or on its industrial uses: this study analyzes the consumer point of view by applying a different methodology compared to existing studies.

Abstract
Purpose
As Generation Z (Gen Z) represents one of the most important segments in the travel and tourism sector, the present work aims to analyse Gen Z's behaviour in a post-pandemic scenario. In particular, the present work deepens the factors that may influence future accommodation choices.
Design/methodology/approach
This study uses data from a web-based questionnaire targeting Italian tourists belonging to Generation Z, reaching 221 complete responses. After the statistical analysis of the sample, an exploratory factor analysis (EFA) was then carried out.
Findings
Data provided evidence about the main factors affecting Gen Z tourist choices. In particular, these young consumers are positively influenced by the information (especially from institutional and verifiable sources), more flexible purchase terms (e.g. full refund in case of cancellation due to contagion of the coronavirus disease 2019 (COVID-19) and digital payments) and structure features (e.g. cleanliness, sanitisation, digitalisation and sustainability).
Originality/value
This work attempts to contribute to the academic literature by looking at the tourism experience from Gen Z's perspective. From this angle, this work underlines the influence some factors exert on the final accommodation choice, especially in the presence of exogenous events. Moreover, as this study focusses on a post-pandemic scenario, the study seeks to provide valuable indications, both at the theoretical and managerial level, for the tourism sector to boost the sector's recovery and prepare the sector to face similar events.

Abstract
An unexpected Coronavirus (COVID-19) pandemic has negatively affected the tourism and the hospitality industry, including luxury accommodation service providers. While this was not the first virus outbreak to impact the tourism sectors, in this case, its consequences were devastating. In this light, this contribution analyzes the case of an Italian luxury hotel, a winner of numerous awards during the last few years, including the prestigious World Luxury Hotel Award. The researchers compare its pre- and the post-COVID situation. They clarify that the outbreak has resulted in reduced reservations and explain how the upscale hotel responded to the unprecedented crisis by implementing different approaches. The luxury hospitality business decided to defend its brand differentiation and positioning strategy by continue offering improved service quality and by introducing enhanced hygiene and sanitation facilities, in order to deliver customer-centric experiences to their valued guests.
