In 1911-1912 Roald Amundsen and Robert Falcon Scott led rival parties in a race to the geographic South Pole. While both parties reached the Pole--Amundsen first--Scott's men died on the return journey. Amundsen became a Norwegian icon through his record-setting travels; Scott became a symbol of courage and devotion to science. The memory of each was invoked at various points during the twentieth century in the context of contemporary Antarctic events. Scott's status as a scientific figure was central to the Scott Polar Research Institute, while Amundsen's lack of scientific legacy became a way for British polar explorers to differentiate themselves from Norwegian contemporaries during the interwar years. After 1945 Scott and Amundsen were again invoked as exemplars of national polar achievement, even as the rise of large-scale science on the continent overshadowed past British and Norwegian achievements. In the present Amundsen and Scott remain wedded to particular values, focused respectively on national achievement and sacrifice in the name of science, while their race has become secondary. 相似文献
Background: Thailand is a poor but highly literate country in South‐East Asia with over 60 million people. A lot of biomedical research is undertaken but dissemination is limited. Objectives: To identify relevant Thai bibliographic databases and investigate accessibility, functionality and content, particularly in relation to randomised controlled trials (RCTs) and clinical controlled trials (CCTs). Methods: A systematic search for institutions productive of research and the databases in their libraries. Search each accessible database in both Thai and English, recording the functionality and content. Assess accessibility of the retrieved RCTs or CCTs by comparing to Pub Med holdings. Results: We found 32 different databases (29 accessible in UK) of various sizes, coverage and functionality but many with unique records of RCTs and CCTs (total, n = 781). Two hundred and nine of 781 trials were accessible on Pub Med (27%). However, 641 of the 781 trial records contain text in both English and Thai (82%) and 112 records were solely English (14%). Conclusions: Those undertaking comprehensive searches for RCTs/CCTs should, in addition to a Pub Med , search the Thai Medical Index and Thai Index Medicus databases, and the Khon Kaen University Library Catalogue. 相似文献

This study explores narratives about critical moments in mathematics learning written by K-8 pre-service teachers’ (PSTs) in the United States over a 20-year period. These critical moments, such as a single memorable task, course, test, or comment from a teacher, had a powerful and sustained impact on PSTs’ mathematics identities, which they carried with them as they entered the teaching profession. We classified narratives using McCulloch et al. (Sch Sci Math 113(8):380–389, 2013) and Drake’s (J Math Teach Educ 9(6):579–608, 2006) categories and found a potentially new category, Taking the Reins. We also classified PSTs’ mathematics orientations as either relational (oriented toward creative problem solving and conceptual understanding) or instrumental (enacting rote procedures without meaning) (Skemp in Math Teach 77(1):20–26, 1976). Many PSTs identified a causal relationship between their mathematics orientations and narrative arcs: relational learning opportunities encouraged positive narratives, while instrumental learning opportunities either resulted in negative narrative arcs or positive but fragile mathematics identities that crumbled under minor stress. We found little variation over time in the nature and prevalence of the narrative arcs and mathematics orientations, suggesting that any changes in mathematics teaching practices over time were not reflected in students’ learning experiences.
This paper begins by defining the term ‘student drop‐out’. Data are presented showing that the time that an external student is at greatest risk of becoming a drop‐out is during the first term, semester or year of study.
The reasons for this phenomenon are explored in the light of the theories of three writers in the field of distance education, namely, Otto Peters, Börje Holmberg and David Sewart.
The paper concludes by listing a number of suggestions that might be adopted in order to reduce early attrition rates and generally improve the functioning of distance education institutions. 相似文献
This second part of a two-part paper describes how the University of California, San Francisco (UCSF) Library implemented a bibliographic control system for a medical illustrations collection. Discussed are the staffing of the project, the design of formats and computer programs, further design changes, the input process, quality evaluation of the illustrations, and production and distribution of the control products (printed indexes and microfiche replicas). The report ends with a note on the applicability of the UCSF system to other libraries, and some benefits of the project. 相似文献
