The role of the library is to assist citizens in skills development critical to national interest and empowerment as literacy ambassadors, in general. Specifically, the work by the Federal Geographic Data Committee (1994) indicates that spatial literacy is for every citizen and not just a set of workforce specialists. Hence, the use of maps in decision making and problem solving will become fundamental to all professions, including library professionals. Thus, a spatial literacy awareness and rationale for such as standard job ability is discussed as a future librarian workforce proficiency and knowledge transfer medium. 相似文献

This paper explores the impact of acculturation conditions, orientations and outcomes on international students in Australia’s tertiary education sector. Specifically, we investigate the factors that facilitate or hinder acculturation of international students within a multidimensional acculturation context (Arends-Tóth & van de Vijver, 2006). We used a sequential exploratory mixed-methods design in two studies to investigate acculturation of international students at an Australian university and test how these factors are related to psychological and sociocultural outcomes. In Study 1, we conducted a generic qualitative study using semi-structured interviews with a conventional content analyses approach,which compared the experiences of international students who on average had high numbers of positive experiences versus those who had high numbers of negative experiences. We found that a support network of mixed-nationals, and especially host locals, facilitates positive psychological and sociocultural adjustment, and buffers acculturative stress. Study 2 quantitatively tested the association of factors found in Study 1 (perceived stereotypes, intercultural and ethnic network/resources) with psychological and sociocultural acculturation outcomes. Study 2, shows that perceived negative stereotypes loosen ties with the dominant (host) culture and reinforces ties with the ethnic (non-host) culture. The social resources associated with either culture was found to be useful for acculturation, with both independently contributing to participant well-being. Contact with host locals played a particularly crucial role in developing these resources. Our findings provide foundations for pragmatic policy implications, suggesting value in the development of formally organized contact programs in the early sojourn experience of international students. 相似文献

ABSTRACT Increased global communication is adjusting traditional models of cross-cultural communication. Specifically, changes in international communication processes have caused increased scrutiny of cross-culture adaptation theory. This is especially true when focusing on the difference between cultural adaptation and functional fitness. The purpose of this research is to address changes in global communications by testing to see if there is a difference between two important theoretical concepts within cross-cultural adaptation theory – linear and non-linear adaptation. Findings indicate that cultural sojourners do not equate cross-cultural adaptation with linear models of functional fitness. Models that equate the two should be revisited. 相似文献

The article presents the results of a quasi-experimental intervention study with a 2 × 2 factorial design. We implemented a problem-based intercultural learning unit in four secondary schools (grades 9 to 12) and varied the teaching approach (analytical/affective-experiential) and the language of instruction (German/English). The learning unit covered six 45-min lessons and was conducted in nine school courses (n = 143). Five additional school courses (n = 66) served as a control group. In all experimental groups, students engaged with critical incidents. These were either analysed (analytical focus) or acted out as role plays (affective-experiential focus). In addition, students analysed film clips (analytical focus) or participated in a simulation game (affective-experiential focus). The experimental groups outperformed the control group in the post-test, which required the analysis of critical incidents. Both teaching approaches were equally effective; however, students evaluated affective-experiential learning more positively. Using a foreign language for teaching did not impair performance. 相似文献
