关于“民国机制”命名和定义研讨的反思——兼与李怡等学者商榷     

徐诗颖 《宜宾师范高等专科学校学报》2014,(5):68-72

李怡于2009年提出关于新的中国现代文学史叙述范式“民国机制”在民国文学研究里取得了方法论上的突破。由于形成时间短暂,它还需要经历诸多现实的考验。在命名方面,“民国机制”实际指的是民国文学机制,它所作用的对象依旧是中国现代文学,实质未能跳出“现代”意义的内涵。同时,研讨还包括“民国机制”划分边界的依据和时空影响。李怡把酝酿“民国机制”的时间定在1912年清王朝覆灭后,依旧未能跳出以“国体和政体”作为文学史划分依据的桎梏。虽然中华民国曾作为一个政权符号存在,但“民国机制”并未能在当时起到决定性的作用。由于李怡并没有对文学史观和价值评判标准作出一个完整的解析,所以学界对民国机制“能包容错综复杂的文学现象”这个命题仍需质疑并继续探索。  相似文献   

A prospective,randomized crossover study comparing direct inspection by light microscopy versus projected images for teaching of hematopathology to medical students          下载免费PDF全文

Instruction in hematopathology at Mayo Medical School has evolved from instructor‐guided direct inspection under the light microscope (laboratory method), to photomicrographs of glass slides with classroom projection (projection method). These methods have not been compared directly to date. Forty‐one second‐year medical students participated in this pilot study, a prospective, randomized, crossover study measuring educational performance during a hematology pathophysiology course. The students were randomized to one of two groups. All students received the same didactic lectures in the classroom and subsequent case‐based review of peripheral blood smears using either laboratory or projection methods, on day one with a crossover to the other method on day two. Pre‐ and post‐test examinations centered on morphology recognition measured educational performance on each day, followed by a questionnaire identifying the student's favored method. There was no significant difference in the pre‐test and post‐test scores between the two teaching methods (rank‐sum P = 0.43). Students overwhelmingly preferred the projection method and perceived it as superior (76%), although post‐test scores were not significantly different. Student's recommended method was split with 50% favoring the projection method, 43% favoring a combined approach, and 23% noting logistical challenges to the laboratory. In this study, the laboratory and projection method were equivalent in terms of educational performance for hematopathology among medicals students. A classroom‐based approach such as the projection method is favored, given the large class sizes in undergraduate medical education, as well as the ergonomic challenges and additional resources required for large group instruction in a laboratory setting.

Evaluation of usage of virtual microscopy for the study of histology in the medical,dental, and veterinary undergraduate programs of a UK University          下载免费PDF全文

This article describes the introduction of a virtual microscope (VM) that has allowed preclinical histology teaching to be fashioned to better suit the needs of approximately 900 undergraduate students per year studying medicine, dentistry, or veterinary science at the University of Bristol, United Kingdom. Features of the VM implementation include: (1) the facility for students and teachers to make annotations on the digital slides; (2) in‐house development of VM‐based quizzes that are used for both formative and summative assessments; (3) archiving of teaching materials generated each year, enabling students to access their personalized learning resources throughout their programs; and (4) retention of light microscopy capability alongside the VM. Student feedback on the VM is particularly positive about its ease of use, the value of the annotation tool, the quizzes, and the accessibility of all components off‐campus. Analysis of login data indicates considerable, although variable, use of the VM by students outside timetabled teaching. The median number of annual logins per student account for every course exceeded the number of timetabled histology classes for that course (1.6–3.5 times). The total number of annual student logins across all cohorts increased from approximately 9,000 in the year 2007–2008 to 22,000 in the year 2010–2011. The implementation of the VM has improved teaching and learning in practical classes within the histology laboratory and facilitated consolidation and revision of material outside the laboratory. Discussion is provided of some novel strategies that capitalize on the benefits of introducing a VM, as well as strategies adopted to overcome some potential challenges.

Developing an audiovisual notebook as a self‐learning tool in histology: Perceptions of teachers and students          下载免费PDF全文

Videos can be used as didactic tools for self‐learning under several circumstances, including those cases in which students are responsible for the development of this resource as an audiovisual notebook. We compared students' and teachers' perceptions regarding the main features that an audiovisual notebook should include. Four questionnaires with items about information, images, text and music, and filmmaking were used to investigate students' (n = 115) and teachers' perceptions (n = 28) regarding the development of a video focused on a histological technique. The results show that both students and teachers significantly prioritize informative components, images and filmmaking more than text and music. The scores were significantly higher for teachers than for students for all four components analyzed. The highest scores were given to items related to practical and medically oriented elements, and the lowest values were given to theoretical and complementary elements. For most items, there were no differences between genders. A strong positive correlation was found between the scores given to each item by teachers and students. These results show that both students' and teachers' perceptions tend to coincide for most items, and suggest that audiovisual notebooks developed by students would emphasize the same items as those perceived by teachers to be the most relevant. Further, these findings suggest that the use of video as an audiovisual learning notebook would not only preserve the curricular objectives but would also offer the advantages of self‐learning processes.

基于垂直扫描显微干涉技术的高精度轮廓仪     

戴蓉  谢铁  邦龚文  常素萍 《上海大学学报(英文版)》2008,12(3):255-260

A profilometer used for 3 dimension measurement of micro-surface topography is presented. The instrument is based on the vertical scanning microscopic interferometry （VSMI）. A Linnik type interference microscope is used and the interferograms which present changes of surface profile are recorded with a CCD camera. A developed nano-positioning work stage with an integrated optical grating displacement measuring system realizes the precise vertical scanning motion during profile measurement. By a white-light phase shifting algorithm of arbitrary step, frames of interferograms are processed by a computer to rebuild and evaluate the measured profile. Because of the specialty of VSMI, the profilometer is suitable for both smooth and rough surface measurement. It can also be used to measure curved surfaces, dimension of micro electro mechanical systems （MEMS）, etc. The vertical resolution of the profilometer is 0.5 nm, and lateral resolution 0.5 μm.  相似文献

企业技术创新悖论及其网络机制干预研究     

毛文静 《科学与管理》2012,(1):62-66

随着市场环境的日趋复杂多变及竞争的日益激烈,技术创新成为提升企业竞争力、促进企业成长和效率非线性提高的重要途径。组织结构是影响企业技术创新能力的重要因素。企业技术创新管理面临着技术和组织上的两难悖论,即企业越是追求高新技术,就越是导致企业偏重内部结构并导致部门之间的隔离,从而越是阻碍了企业技术创新;高生产率、产品商业化创新和创新信息管理都需要一个严格等级分明的组织,而新技术发明和创意都要求比较灵活机动的、非等级制的组织形式。企业内外的合作网络机制是解决技术创新的两难悖论、提高创新绩效的关键。  相似文献
