Sustainable tourism is essential for tourism sector development. Environmentally responsible behaviors and behavioral intentions are important prerequisites for sustainable tourism. This research explores the behavioral intentions of university tourism students and significant factors affecting these behavioral intentions. The questionnaire survey method was applied to university students from the tourism departments of nine universities in Taiwan. A total of 390 valid questionnaires were collected. The pro-environmental behavioral intentions of the students ranged from moderate to high. Environmental knowledge positively affected behavioral intentions and positively influenced environmental sensitivity and environmental responsibility. Furthermore, environmental sensitivity and environmental responsibility exerted a full effect in mediating the relationship between environmental knowledge and behavioral intentions. Hence, increasing students' environmental knowledge will enhance their behavioral intentions. However, by improving students' sensitivity and responsibility, their intentions to protect the environment can be more effectively elevated. Development implications and recommendations for sustainable tourism and higher education are provided.

Baseball spectating is one of the most popular leisure activities in Asia. Leisure participants with high well-being levels usually demonstrate loyal behavior to the teams they follow. Previous research indicates that professional sport fans are serious leisure participants and their participation has career qualities. The goal of this research was to investigate the relationship of leisure involvement with the well-being of professional sport fans and the possible mediating effect of organizational commitment, a career-related characteristic, on well-being. Some 406 fans of the Brother Elephants Baseball Team in Taiwan were surveyed. The results showed that leisure involvement positively and significantly influenced fans' well-being and organizational commitment partially mediated the influence of leisure involvement on well-being. This study pioneers the integration of leisure involvement, well-being and organizational commitment in the context of a Professional Baseball League team within Asia. Implications and future research directions are presented.
