ABSTRACTVisitor experiences and interpretation at wildlife tourism sites are often designed to encourage visitors to adopt conservation actions. Typically, conservation messages are delivered via one-size-fits-all interpretive signage, with little consideration given to whether the same information attracts and engages different cultural groups. This study explores Chinese and international visitors’ perceptions of signage at the Chengdu Research Base of Giant Panda Breeding in China. Four sign prototypes were designed and a combination of visitor observations, interviews, and exit surveys were used to test their attracting and holding power. Comparisons of Chinese and Western visitors revealed no significant difference in the proportion who stopped to read signs. Preferences for signage elements were also similar across the two cultural groups; however, there were differences in terms of what visitors thought should be included in wildlife interpretation. Implications for the design and delivery of interpretation in Chinese wildlife tourism settings are discussed. 相似文献

We identified leaders’ achievement goals and composition of creative input as important factors that can clarify when and why leaders are receptive to, and supportive of, subordinates’ creative input. As hypothesized, in two experimental studies, we found that relative to mastery goal leaders, performance goal leaders were less receptive to subordinates’ voiced creative input. In Study 1, we further showed that image threat appraisal and learning opportunity appraisal mediated this effect. In Study 2, we demonstrated that when merely creative ideas were expressed by the subordinate, performance goal leaders responded like mastery goal leaders. However, as in Study 1, performance goal leaders were less receptive to, and less supportive of, subordinates’ creative input than mastery goal leaders when the composition of subordinates’ creative input included both problem identifications and creative ideas. 相似文献

The debate continues with regard to whether degradation of semantic knowledge or deficits in information processing lead to impaired memory performance in patients with Alzheimer's disease (AD). This study examined the effects of semantic content and working memory demands on the recall and recognition abilities of patients with mild AD. Nineteen patients with probable AD and 19 demographically matched normal control participants were asked to remember prose passages that varied in semantic content (high, medium, and low level of idea importance) and working memory demands (narrative and expository passages). Compared to the controls, patients with mild AD lost the ability to recall prose in a manner consistent with the semantic structure of the passages as the demands on working memory increased. Furthermore, as the demands on working memory increased, patients recognized information in a manner that suggested their initial processing was of isolated details rather than by semantic structure. This study provides support for the hypothesis that information processing deficits contribute to impaired semantic processing in patients with mild AD. 相似文献
