Cross-border e-commerce(CBRC) is increasingly affecting the value of traditional trade due to its rich variety, convenient operation, and free of time and space restrictions, and has also changed the consumer's Shopping habits. However, the development of CBEC still faces many problems, resulting in domestic consumers' willingness to consume on CBEC platforms is not high. Based on the above background, the research content of this paper is the influence of consumer trust on purchase intention based on perceived risk of CBEC platforms. In this paper, a questionnaire survey is used to collect data for simulation. The results show that from the regression results of the five dimensions of trust on purchase intention, the adjusted R2 is 0.466, indicating a high degree of fit. When the exploratory value in perceived promotional gains is high, it will leave consumers in an irrational state and weaken the perception of risk.

Vaccines have saved millions of lives and reduced the severity of many infections, but today the reduction in vaccine coverage has been reflected in the resurgence of epidemics of mumps, whooping cough, measles and chickenpox. This has happened because many people do not recognize the effectiveness of vaccination and fear the side effects, in other words, the main concern is the safety of the vaccines. As a consequence, the greater responsibility of the individual and respect for his will can lead authorities to less vigorously promote the “duty of vaccination”, which is also a social duty. Unfortunately, however, the attitude of individuals is guided by their beliefs about health, which are often supported by an erroneous perception of risk arising from false news.

The purpose of this study was to determine the impact of the risk perception of tourists on the intention to travel to Sabang City in the midst of the Covid 19 pandemic. This research is based on the theoretical framework of the theory of planned behavior (TPB). Sample approach using Non-Probabilityaccidental sampling.The sample amounted to 200 respondents who came from within and outside the province of Aceh. The results of this study indicate that the perception of risk has a negative and significant effect on the antecedents of Intention, namely Attitude, Behavioral Control, and Subjective Norms. Attitudes and Behavioral Control each have a positive and significant effect on the intention of tourists visiting Sabang City during the covid 19 pandemic. Meanwhile, Subjective Norms have no significant effect.

Despite the danger of the spread of the COVID-19 pandemic, visits to natural tourism destinations such as national parks are continuing, though people are using less congested trails or minimizing personal contact. Given the danger from COVID-19, the purpose of our study was to use an expanded theory of planned behavior to analyze whether tourists intend to continue to visit national parks. Another purpose for our study was to compare an extant research model based on the theory of planned behavior with the extended model we developed. Frequency analysis, confirmatory factor analysis, structural equation modeling, and other statistical techniques, such as correlation analysis, parsimonious fit index, and squared multiple correlations were employed according to the appropriate objectives. Additionally, the number of 351 participants joined the survey. Our study found that perception of risk of COVID-19 negatively affected attitude and perceived behavioral control in both models. Moreover, the perceived behavioral control had a positive effect on coping behavior. Given the analytical results, our study presents not only theoretical implications for understanding the behavior of those who visit national parks, but also practical implications for operation and management of national parks during the COVID-19 pandemic.

Safety of navigation is the important issue especially related to the dynamically developing container shipping. The main purpose of the article is to demonstrate the results of research on the perception of risk factors by seafarers working on container ships in terms of their professional experience. The ranking of risk factors considering their impact on the safety of container shipping has been created. An additional goal of the research was to acquire the knowledge on ships crews members' assessment of the impact of the human factor on the safety of navigation, including factors related to the organization of seafarers' work (systemic aspects) and those directly resulting from the operations carried out on ship. The assessment of risk factors affecting the navigation safety was performed from the perspective of Polish crew members working on container ships. The research was carried out with the use of an empirical study questionnaire. 161 seafarers' opinions were analyzed. On the basis of the created risk factors ranking analysis, it was found that seafarers perceive the human factor, and consider both the systemic and the work-related aspects having the greatest impact on the safety of container shipping. Moreover, the conducted non-parametric Pearson chi-square independence test proved the hypothesis that assessments of the five highest rated risk factors, reviewed by studied young and experienced professional groups of seafarers, didn’t differ significantly.
