Festivals and events are important activities related to enhancing the image of the destination. Modern festivals are spread all over the world, not only changing the rhythm of daily life but also bringing more development possibilities for the places where these festivals are held. In order to learn more about tourists’ experiences in emerging events, a detailed study of famous hot air balloon festivals was conducted in Taitung City, Taiwan. Based on the stimulus-organism-response (S-O-R) model, the purpose of this study is to explore the relationship among these three constructs, namely stimulus: perception of marketing strategies and motivation, organism: positive emotions and satisfaction and response: revisit intention. Face-to-face surveys were conducted on-site in 2014 and 2018, a total of 896 valid questionnaires were collected from tourists who visited the Taiwan International Balloon Festival. SPSS Macros PROCESS was used to examine the measurement model. This study confirms the application of the S-O-R model in predicting tourists’ revisit intentions in the context of emerging events in the tourism industry. The survey results show that whether in 2014 or 2018, tourists’ satisfaction and tourists’ positive emotions can mediate the relationship between tourists’ perception of marketing strategies (or tourist’s motivation) and tourists’ revisit intention. Moreover, only in 2018, tourists’ visiting frequency can moderate the relationship between satisfaction and revisit intention.

Although the health belief model (HBM) has been widely applied in health behavior research, it cannot fully account for dietary supplement (DS) consumption. This study proposed a second-stage moderation model to empirically examine the mediating role of product knowledge and the moderating effects of trust and distrust in the HBM. Surveys were conducted both online and offline in first-tier Chinese cities; 768 effective samples were collected. Structural equation modeling was employed to test the hypotheses. The findings indicated that perceived susceptibility was a better predictor of attitude toward DS products. Second, perceived susceptibility’s effect on product attitude occurred through product knowledge. Third, trust in manufacturers positively affected product knowledge’s effect on product attitude. Based on these findings, to promote DS consumption, marketers can leverage consumers’ perceived susceptibility to illness, associate the benefits and efficacy of DSs with consumers’ health knowledge, and emphasize their production of high-quality DSs.

In recent decades, food safety has become a major concern due to frequent food safety incidents in many countries. This may lead to increased health risks associated with low quality food consumption, thereby reducing consumer trust in food safety. A better understanding of consumer perceptions of food safety can improve indicators that do not meet consumer expectations. We propose a food safety gap model with four gap-construct based on consumer expectations and perceptions. The model was empirically tested through a survey of 25 items, and then assessed for gaps through the importance–performance analysis (IPA). From a sample of 697 Taiwanese consumers, we found a huge gap between consumer expectations and perceptions related to food safety. More importantly, the results of the IPA indicate that most items must be immediately improved, which is vital in order to mitigate the risk of food safety.
