AbstractThe Hong Kong Library Association (HKLA) has been the core organization serving the library and information science (LIS) community in Hong Kong since its establishment 62?years ago. It organizes activities and events continually to enrich professional knowledge of LIS professionals in Hong Kong. It has been observed that the number of student members has risen constantly in recent few years. In view of the pressing demand for better support to student members, the HKLA launched the Mentoring Program in 2013 to enhance informal communication between student members and other members of the Association. The Mentoring Program received an overall positive feedback from the local LIS community and made a positive impact to participants, especially mentees. Apart from the successful experience of this program, there are issues that can be improved in sustaining this program in long term. This paper summarizes the experience of implementing the Mentoring Program in the first two years and identifies the challenges and opportunities ahead. The finding indicates that the Mentoring Program was a well-received professional development program for the student members of the Association. However, this program can be further enhanced in terms of mentor solicitation, mentor-mentee eligibility, mentor-mentee relationship, knowledge-based interaction, and program sustainability. The Program Committee may consider collaborating with other LIS agencies to solicit more potential mentors. In view of the population of the potential mentors, it makes very good sense for the past mentees to serve as peer-to-peer partners for non-degree student members. More incentive should be devised to encourage the mentoring pairs in joining library events in addition to the activities related to the Mentoring Program. To facilitate communication and experience sharing among program participants and HKLA members, it is desirable to set up an online discussion platform to address the increasing demand for more opportunities on this. Lastly, it is vital to improve communication among the Program Committee, HKLA Council members and HKLA members. Besides reviewing the operation and management of the Mentoring Program, the Program Committee should also study the feasibility of sustaining this program in the long run. This paper can be served as an empirical study on the implementation of library and information science mentoring programs in one of the major cities in Asian region. The results of the study can be referenced by the LIS community not only locally but also internationally. 相似文献

ABSTRACTThe tomb of Tutankhamen in the Valley of the Kings, Egypt, one of the major attractions of the World Heritage Site of Ancient Thebes and its Necropolis on the West Bank of modern day Luxor, is today a destination for mass tourism. Visitors to the tomb increase relative humidity, elevate carbon dioxide levels, and encourage natural ventilation which facilitates entry of dust into the tomb. These conditions negatively impact the wall paintings and remaining artifacts in the tomb and create an uncomfortable environment for visitors. The deposition of dust inside the tomb collects on uneven wall painting surfaces, obscures their legibility and necessitates cycles of cleaning, which in turn leads to further damage. Developing environmental management strategies in the tomb to counter the effects of visitors and mitigate dust entry is an important component of the collaborative project between the Getty Conservation Institute (GCI) and Egypt’s Ministry of Antiquities (MoA) to conserve the tomb. These included implementation of a filtered-air supply and exhaust ventilation system to stabilize the interior microclimate and reduce dust in order to improve visitor comfort and contribute to the long-term preservation of the tomb. 相似文献

近代中国的海外移民在迁出地上主要集中于闽粤地区,在迁入地上主要集中于东南亚地区。在南中海地区,移民行为与华商的贸易网络一开始就紧密联系在一起,就源起上讲,两者几乎是同步进行的。在近代,一方面,移民行为使得华商跨国贸易网络不断扩展,同时也为网络规模的扩大提供了强有力的“外部经济”支持,另一方面,华商网络的存在使移民行为在新的关照下被赋予了新的内容和涵义,更进一步拓展了海外移民理论的研究。 相似文献

This article develops a theoretical context for the influence of personality traits on commenting behaviors on online news Web sites. Drawing on the literature of personality, and online behaviors, we examine how personality traits may influence which individuals make contributions on news Web sites. Additionally the article focuses on how the commenting “landscape,” in particular moderation policies and user interfaces, may impact those who contribute. 相似文献

How can students be taught to develop explanations for scientific phenomena on their own when their background knowledge is incomplete or poorly organized? Evidence from historical accounts of scientific discovery suggest that self-generated analogies—analogies produced by the learners themselves—are a tool by which individuals can generate, evaluate, and modify their own explanations. The central research questions for this study were: Can students use a series of self-generated analogies to bring about change in their understanding of a given scientific phenomenon, and what is the nature of the change in understanding? Participants were asked to create, apply, and modify their own analogies—as opposed to applying a specific analogy provided by an outsider—as a heuristic for constructing, evaluating, and modifying their own explanations for a given scientific phenomena. Nontrivial changes in explanation facilitated by the use of generative analogies were observed. Changes in understanding ranged from the emergence of new explanations to the raising of important questions about the nature of the phenomenon. 相似文献
