台湾地区大学图书馆电子书使用现况调查 总被引:2,自引:0,他引:2
由于数字出版的发展,电子书已在台湾的大学及技专校院图书馆占重要地位。为了解大学师生对这些电子书的使用状况,台湾学术电子书联盟于2010年进行了大规模的使用调查。调查问题包括:大学师生是否使用过图书馆的电子书,使用频率为何,透过何种管道查询电子书,使用电子书的意愿为何,使用电子书的动机为何,使用电子书遇到的问题及需要协助的困难为何,哪些是用户重视的电子书质量及功能,对于台湾学术电子书联盟引进的电子书满意度如何。调查采用在线问卷,共有91个学校,26,120位教职员生填答。调查发现,大学教师、研究员及研究生使用过电子书的比例高达六成以上;在同时有纸本书及电子书的情况下,半数以上的教师、研究员及研究生会优先选用电子书,但大学生仍喜爱纸本图书;对于电子书的质量,用户重视的是全文影像是否清晰、搜寻功能是否良好、使用接口是否易于操作、浏览方式是否便利、全文阅读方式是否符合需求等。另外,找不到所需的电子书,是读者最常遇到的困扰,显示图书馆的电子书种类仍不足以应付使用者的需求。 相似文献

Previous work on new teacher professional identity has focused on identity as a process of negotiation between individual and contextual factors. These negotiations are often filled with a struggle between personal agency and structures that prevent the enactment of an ideal professional self. This study introduces and discusses three teacher professional identity orientations (self, classroom, and dialogic) and the implications of each orientation on a teacher’s professional identity and classroom practice. While each focal teacher featured in the study drew from similar sources of professional identity (experiences as students, classroom practical experience, and theory/research), the teachers varied in the degree of importance accorded to each identity source. This variation led to differences in approach to their roles as teachers as well as differences in their work with students. Using a qualitative, comparative case study methodology to highlight features of each professional identity orientation, this study provides evidence of discourse related to each orientation and discusses implications of identity orientation in each case study teacher’s classroom practice. After the discussion and analysis of the data, the author offers recommendations for teacher educators (pre-service and in-service) and researchers related to understandings of professional identity development and implications for the work of pre-service teacher education and continuing professional development. 相似文献

Primary hemostasis and blood clotting is known to be influenced by the red blood cell volume fraction (hematocrit) in blood. Depressed or elevated levels of red blood cells can lead to vascular perfusion problems ranging from bleeding to thrombus formation. The early stage of hemostasis and thus blood clotting in all vessel sections from the arterial to the venous system involves the adhesion of platelets to von Willebrand factor. Here we present experimental and theoretical results showing that the adhesion probability of platelets to von Willebrand factor is strongly and nonlinearly dependent on hematocrit and flow rate. Interestingly, the actual binding forces are not markedly different, which suggest that the origin of such behavior is in the distribution of platelets. Using hydrodynamic simulations of a simple model, we explicitly show that the higher the hematocrit and the flow rate, the larger the amount of platelets residing close to the wall. Our simulation results, which are in excellent agreement with the experimental observations, explain why such phenomena occur. We believe that the nonhomogeneous red blood cell distribution as well as the shear dependent hydrodynamic interaction is key for the accumulation of platelets on the vessel wall. The work we present here is an important step forward from our earlier work on single molecules and extends into the collective cellular behavior of whole blood. It sheds new light on the correlation between hematocrit and the initial steps in hemostasis and thrombosis, and outlines advances for the treatment of vascular diseases associated with high levels of red blood cells. These results are not only highly relevant for the field of hemostasis and the physics of blood clotting but are also of powerful impact in applied science most obviously in drug delivery and colloidal science. 相似文献

This single-subject study assessed the effects of in-classroom coaching on early childhood teachers’ use of emergent literacy teaching strategies. Teaching strategies were grouped into clusters related to oral language and comprehension of text, phonological awareness and alphabetic principle, and print concepts and written language, with coaching being applied to each cluster separately. The coaching process included two primary components: a brief initial meeting to introduce teaching strategies in the cluster, and semi-weekly observation with follow-up discussion using data collected during the observation. A third, booster component was added when the teacher did not achieve a pre-established criterion. Participants were five early childhood teachers, three in child care programs and two in public school pre-kindergarten programs. The intervention phase lasted approximately 6 weeks for each teacher. Results indicated that this approach to coaching was effective for increasing the number of teaching strategies that teachers used in each cluster. Individual differences among teachers are discussed, and implications for future research and practice are explored. 相似文献

There has not been enough critical analysis of children’s literature by and about Chinese Americans, especially when compared to other minority groups in the United States. In particular, Chinese American historical books lack extensive analysis. It is important to reflect cultural accuracy in literature and to help children develop clear concepts of self and others by providing precise cultural and physical characteristics of people. While cultural authenticity allows children the opportunity to see a reflection of real experiences within a book instead of seeing stereotypes or misrepresentations, obtaining correct information about a certain time period can help children to see images of immigration accurately represented in literature. Using the Confucian delineation of interpersonal relationships as the major criterion of cultural authenticity, this article examines three currently available children’s picturebooks set in the historical period between 1848 and 1885. In addition to exploring how Chinese Americans’ interpersonal relationships are portrayed in these children’s historical books, this article argues for more proactive inclusion of the diversity in selection of picturebooks. 相似文献
