2D Helium Atom Diffraction from a Microscopic Spot.

A method for measuring helium atom diffraction with micron-scale spatial resolution is demonstrated in a scanning helium microscope (SHeM) and applied to study a micron-scale spot on the (100) plane of a lithium fluoride (LiF) crystal. The positions of the observed diffraction peaks provide an accurate measurement of the local lattice spacing, while a combination of close-coupled scattering calculations and Monte Carlo ray-tracing simulations reproduce the main variations in diffracted intensity. Subsequently, the diffraction results are used to enhance image contrast by measuring at different points in reciprocal space. The results open up the possibility for using helium microdiffraction to characterize the morphology of delicate or electron-sensitive materials on small scales. These include many fundamentally and technologically important samples which cannot be studied in conventional atom scattering instruments, such as small grain size exfoliated 2D materials, polycrystalline samples, and other surfaces that do not exhibit long-range order.

COVID-19 and Pro-environmental Behaviour at Destinations Amongst International Travellers.

This paper investigates the COVID-19 pandemic, and its impact on pro-environmental behaviour of individuals travelling internationally for leisure and recreational purposes. The aim of this manuscript is to investigate a conceptual framework created through the examination of current existing literature in the field of tourism science. The conceptual framework, consisting of certain constructs of the health belief model (HBM), and the theory of planned behaviour (TPB), is applied and tested using a partial least-squares-structural equation modelling (PLS-SEM). Data were collected from participants who have travelled internationally before and during the outbreak of the COVID-19 pandemic, and those who plan to travel post-COVID-19 pandemic. Results revealed that the conceptual framework tested positively against existing theory, highlighting the key influencing factors in which COVID-19 is likely to have on future pro-environmental behaviour of individuals travelling internationally for leisure and recreational purposes. Moreover, perceived safety threat and outcome expectations have a positive impact on attitude; attitude has a positive impact on behavioural intentions; subjective norm has a positive impact on behavioural intentions, and perceived behavioural control has a positive impact on behavioural intentions. The study results identify practical and theoretical implications for global and travel companies and organisations, presenting opportunities to adjust environmental policies and procedures accordingly, whilst identifying the most effective marketing and management strategies to rebuild a collapsed global travel industry.

Intention to Take COVID-19 Vaccine as a Precondition for International Travel: Application of Extended Norm-Activation Model.

The COVID-19 pandemic is a serious threat to human health, the global economy, and the social fabrics of contemporary societies as many aspects of modern everyday life, including travel and leisure, have been shattered to pieces. Hence, a COVID-19 mandatory vaccination as a precondition for international travel is being debated in many countries. Thus, the present research aimed to study the intention to take the COVID-19 vaccine as a precondition for international travel using an extended Norm-Activation Model. The study model integrates a new construct, namely mass media coverage on COVID-19 vaccination as additional predictor of intention to take the COVID-19 vaccine. The survey data were collected from 1221 international travelers. Structural equation modelling shows a very good fit of the final model to the data; the conceptual model based on extended Norm-Activation Model was strongly supported. Awareness of consequences related to the COVID-19 pandemic on individuals' health has shown a positive effect on individuals' ascribed responsibility to adopt emotionally driven (anticipated pride and anticipated guilt) pro-social behaviors that activate a personal norm towards altruistic and pro-mandatory vaccination-friendly behavior. Theoretical and practical implications are discussed.

Halal Food Performance and Its Influence on Patron Retention Process at Tourism Destination.

Muslim tourism is one of the most rapidly developing sectors in the international tourism industry. Nevertheless, halal food performance and its relationship with international Muslim traveler decision-making and behaviors have not been sufficiently examined. The present research explored the influence of halal food performance, which encompasses availability, health/nutrition, accreditation, and cleanness/safety/hygiene factors, on the Muslim traveler retention process at a non-Islamic destination. A survey methodology with a quantitative data analytic approach was employed to achieve research goals. Our findings indicated that halal food performance increased destination trust and destination attachment, which in turn influenced Muslim traveler retention. Additionally, the efficacy of the higher-order framework of halal food performance was defined. Both destination trust and attachment mediated the effect of halal food performance on retention. A halal-friendly destination image included a moderating influence on the retention process. The effectiveness of the proposed theoretical framework for explicating Muslim traveler behaviors was uncovered. This research better introduces the importance of halal food performance and its attributes for the elicitation of Muslim traveler approach responses and behaviors at a non-Islamic destination to researchers and practitioners.

Cruise ship dining experiencescape: The perspective of female cruise travelers in the midst of the COVID-19 pandemic.

The cruise dining experience is one of the core elements of the overall cruise travel experience as guests fulfill their cognitive and affective needs in this pleasant environment. Nonetheless, the cruise dining experience has been sparsely researched. There is also no holistic model conceptualizing the cruise ship dining experiencescape. This study explores how under the influence of the COVID-19 pandemic, cruise ship dining environment stimuli dimensions are evaluated by female cruise travelers. Female travelers are the major spenders and travel decision-makers. They are also the dominant customer group in the cruise sector. Their perception of cruise ship dining environment is leading to their positive emotional responses and approach behavior. More precisely, this study demonstrates the potency of the moderating role of a perceived health risk from COVID-19, which strengthens female travelers' perceptions of the dining atmosphere and interaction with other guests by evoking positive emotions and influencing their approach behavior.

The Post-Coronavirus World in the International Tourism Industry: Application of the Theory of Planned Behavior to Safer Destination Choices in the Case of US Outbound Tourism.

The tourism industry has been seriously suffering from the coronavirus disease (COVID-19) crisis ever since its outbreak. Given this pandemic situation, the major aim of this study is to develop a conceptual framework that clearly explains the US international tourists' post-pandemic travel behaviors by expanding the theory of planned behavior (TPB). By utilizing a quantitative process, the TPB was successfully broadened by incorporating the travelers' perceived knowledge of COVID-19, and it has been deepened by integrating the psychological risk. Our theoretical framework sufficiently accounted for the US tourists' post-pandemic travel intentions for safer international destinations. In addition, the perceived knowledge of COVID-19 contributed to boosting the prediction power for the intentions. The associations among the subjective norm, the attitude, and the intentions are under the significant influence of the tourists' psychological risks regarding international traveling. The comparative criticality of the subjective norm is found. Overall, the findings of this study considerably enhanced our understanding of US overseas tourists' post-pandemic travel decision-making processes and behaviors.

Fear and Trembling of Cruise Ship Employees: Psychological Effects of the COVID-19 Pandemic.

The current COVID-19 pandemic has evolved to unprecedented proportions. This research aimed to gain a deeper understanding of the psychological effects of the COVID-19 pandemic on cruise ship employees stuck at sea. Using an inductive qualitative approach, a synchronous online focus group was conducted with nine cruise ship employees who were stuck at sea during COVID-19 pandemic. The findings revealed that COVID-19 pandemic has managed to erase the feeling of joy from cruise ship employees who were stuck at sea while exposing weakness of cruise line companies such as poor human resource management leadership. Moreover, COVID-19 pandemic demonstrated that it is of paramount importance that cruise line companies create a comprehensive strategy in assisting their employees who are experiencing an anxiety disorder and depression. The managerial implications are outlined.

Connected at Sea: The Influence of the Internet and Online Communication on the Well-Being and Life Satisfaction of Cruise Ship Employees.

This study aims to elucidate the idiosyncratic effects of the Internet and online communication on the well-being and life satisfaction of cruise ship employees. Cross-sectional surveys and covariance-based structural equation modelling tools were used. In addition, univariate variance analysis was used to address the effects of socio-demographic variables (years of service on a cruise ship, working department on a cruise ship, gender, age, educational level and place of residency) on latent variables of the conceptual model. The conceptual model draws on existing theory and previous research and was empirically tested on a sample of cruise ship employee internet users. Result show that while being onboard a cruise ship, employees experience strong social pressure to be constantly available and they fear of missing out on important information and life events. Thus, relatedness to friends and family needs satisfaction is of paramount importance for cruise ship employees because they are fully aware that they are dispensable and replaceable to cruise ship companies, however to their friends and family, they are indispensable and unique. Moreover, employees who engage in other tasks/activities while taking part in online communication with friends and family exhibit reduced performance, which leads to poor interaction and social dissatisfaction. Lastly, employees experiencing under-reciprocating exchanges show significant negative effects on their well-being. Overall, the results provided several important theoretical and practical implications relevant to cruise tourism and human resource management.
