Fear of Deportation in High School: Implications for Breaking the Circle of Silence Surrounding Migration Status

Long-term ethnographic data on the daily lives of undocumented students, their teachers, and administrators reveal the effects of fear of deportation (De Genova,?2002) on the routine of a high school. Thirty years after Plyler v. Doe guaranteed the educational rights of undocumented students, this study finds many factors contributing to the creation of a Circle of Silence around these students’ rights and access to schooling that threatens the educational opportunities of a significant population of immigrant students. The implications of this study reveal how schools can become a space to interrupt this vicious cycle through awareness, counseling, and advocacy.     

Developing an audiovisual notebook as a self‐learning tool in histology: Perceptions of teachers and students

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.

Literacies through media: identity and discourse in the process of constructing a web site

In this research note we explore how children construct their identity in the context of a literacy practice: developing written and audio-visual texts in small-group situation to be published on the Internet. Through their dialogue, a shared identity is growing on the context, and every children create an identity as member of a community in which is included [Wenger, E. (1998). Communities of practice. Learning meaning and identity. Cambridge: CambridgeUniversity Press].Methodologically we have adopted, on one hand, an ethnographic perspective (Atkinson et al., 2001) and, on the other, an action-research perspective [Reason, P., & Bradbury, H. (Eds.) (2001).Handbook of action research. London, Thousand oaks Sage]. We analysed the data collected in five groups in an after-school workshop, during a one-month period with eight two-hour sessions. It is particularly important to compare the history of every group creates a different identity for its page.Our findings illustrate how the participants, with their multiple identities [Gee, J.P. (1999). An introduction to discovers analysis. Theory and method. London, NewYork: Routledge], generate a collective identity orientated to a common audience writing as a group, and negotiating during their dialogue. We analyse how these multiple identities turn into a shared identity that, finally, is shown in the product (the Web site).The discussion of our results reveals how the process of creating the web pages, in the situation described above, depends on the shared construction of meanings among the participants. Writing on the Internet about the media facilitates multiple dialogues and provides opportunities to educate children in the use of multiliteracies.     

骨胳肌在乳酸生成和清除中的作用

关于骨胳肌与乳酸代谢的研究已取得了很多重要进展。论述了不同强度运动时骨胳肌乳酸的生成及不同肌纤维清除乳酸的途径。以往认为骨胳肌无糖异生作用，但现在研究认为骨胳肌肌纤维具有糖异生作用。

对西方新闻价值理论的考察与思索

西方新闻价值理论是在长期的新闻实践中逐步形成和确立的。一方面,它是西方新闻实践发展的结果,另一方面,它也是西方对价值认识的反映。纵观一个半世纪以来新闻价值观念在西方的确立,新闻价值标准经过了长时期的孕育,代表了某种智慧的历史积淀,并且取得了大体一致的看法。影响力、接
