A statistical test is applied to explore the possibility that children can affect the efficiency with which parents consume. Parents may receive some economic benefits from children in the form of reverse integenerational transfers that occur because of a positive influence children have on family behavior. Results show that not only do children have an influence on parental consumption, but also that the influence is beneficial. In fact, not accounting for such a benefit could cause an underestimate in such measures as the rate of return to education or the benefits from such governmental programs as Head Start.  相似文献

Using interviews conducted with 24 higher skilled working tourists employed as guest language instructors in the Republic of Korea, this paper explores how working tourists could secure an optimal leisure lifestyle in their host countries. Three key findings emerged. First, the respondents were seeking casual, touristic, amateur, hobby and volunteer leisure with their colleagues and with their host community members. But, the rewards and episodic aspects of their leisure, including formal and informal language development, suggested that it incorporated variations in project-based leisure as a core characteristic. Second, these respondents were taking part in guest, host and leisure speech communities that were each offering leisure choices. However, their leisure lifestyle was best when leisure, second language development and acculturation coincided in a leisure speech community. Third, that in a leisure speech community, respondents’ acculturation and friendships improved more so than in either guest or host speech communities. Also, that these respondents’ formal and informal second language learning within their leisure speech communities was essential for an optimal leisure lifestyle. The paper determines that leisure speech communities, occurring along a continuum of monetary, educational and interpersonal resources, could affect the linguistic mobility of higher skilled working tourists. It recommends that future research could examine if a sociolinguistics of leisure could assist in exploring and mapping the leisure lifestyles appearing among mobile populations in a globalising world.  相似文献

Wildlife tourism is a huge global market, the revenue from which can promote local livelihoods and tourist education, enact conservation, and improve animal welfare. Such benefits arise if wildlife tourist attractions (WTAs) prioritise ethical deliverables above financial profit, but recent work has shown that the majority of WTAs have substantial negative animal welfare and conservation impacts. In the absence of global regulatory authorities, tourist revenue has become the ultimate arbiter of what constitutes acceptable use of animals in WTAs. Tourists, however, are not adequate assessors of WTAs’ animal welfare and conservation impacts: they lack the specialist knowledge required and are subject to a number of psychological biases that obscure the ethical dimensions of decisions to attend particular WTAs. This inadequacy is evidenced, and compounded, by overwhelmingly positive reviews on TripAdvisor (the industry-leading review site), even for WTAs with objectively poor ethical standards. Our suggested solution is to empower tourists by presenting unequivocal assessments of WTAs' animal welfare and conservation impacts, hosted in the fora that tourists already use to make their travel decisions. We would thereby promote a subjective norm that tourists should consider and limit their individual negative impacts when choosing which WTAs to visit.  相似文献

Preparing qualified graduates for the tourism and hospitality industry who will stay and achieve promotional success is paramount. The objectives of this research project were to determine promotional advancement expectations and strategies to improve promotional opportunities. Two separate questionnaires, with both open and close-ended questions, were sent to upper classmen/women in hospitality and tourism programs and alumni of the same programs. In total, 717 (409 students and 308 alumni) completed the questionnaires. Chi-square tests were run to determine differences between student and alumni responses. To assist in analysis of open-ended responses, Atlas.ti was used. There was a statistically significant difference between students and alumni responses in regards to promotional expectations; students expected it to take a significantly longer time to receive a promotion to supervisor or manager than alumni. Overall, students and alumni indicated strategies such as more real-world-focused courses with hands-on experiences.  相似文献

Using a sample of 233 front-line hotel employees, we examined leader–member exchange (LMX), envy, and organizational citizenship behavior (OCB). The results from path analysis support the research model that employees who have a relatively poor working relationship with their supervisor (i.e., low-quality LMX relationship) were more likely to show higher levels of envy than employees who have relatively closer working relationships with the same supervisor (i.e., high-quality LMX relationship). Ultimately, higher levels of envy decreased employee voluntary helping behavior (i.e., organizational citizenship behavior, OCB) toward coworkers. This finding suggests that employees perceiving a poor working relationship with their supervisor committed less voluntary helping behavior toward coworkers than their counterparts. Implications for managers and suggestions for future research are discussed.  相似文献

A number of states require or are considering the required teaching of consumer education in secondary schools. However, almost all previous research has found no difference in consumer economic competency between students who had taken a consumer education/economics course and students who had not taken the course. This research was conducted in a state that requires consumer education of all students to see if there was a change in competency level and attitudes toward business. Potential differences in types of courses used to meet the state requirements were also investigated. The basic finding is that students who took a course specifically designed to present consumer education topics did improve their consumer economics competency and developed a more positive attitude toward business.  相似文献

Supermarkets are starting to adopt price scanning checkouts. Other supermarkets, both scanner equipped and non-scanner equipped, are removing individual item prices. Although much has been written, especially in the retail trade press, about the advantages to retailers of scanner check-outs little attention has been paid to shopper reactions. This study sought to determine the attitudes and behavior of shoppers at scanner equiped supermarkets. Some user reactions to self-price marking of purchases was also determined.  相似文献
