Ira Shor's book, When Students Have Power, provides a detailed account of negotiated learning in a contemporary university setting. Weaving recollections of personal experience with educational theory, Shor builds a rich, complex picture of his unique approach to critical pedagogy. This article draws attention to some of the key stylistic and substantive strengths of the book, considers the question of how authority might best be exercised in the classroom, and comments on some of the limits to liberating education. 相似文献

Despite substantial literature on the dyeing of textiles, there is a lack of research about colouring Japanese mending papers (tissue papers) used for paper conservation purposes. This study investigates the fungal bioreceptivity of Japanese tissue papers after they have been treated with various dyes and pigments. A variety of toning materials including plant dyes, watercolours, acrylic paints, inks, pastels, gouaches, and colour pencils are commonly used by conservators for paper toning purposes. In this study, two Japanese tissue papers (Yukyu-shi and Sekishu Mare) were treated with selected plant dyes, watercolours, and acrylic paints and then inoculated with fungal species. Quantitative real-time polymerase chain reaction (qPCR) was used to quantify the DNA from Aspergillus niger and Penicillium rubrum as a proxy for fungal species abundance before and after inoculation and artificial moist heat ageing. qPCR primers which were universal for fungi amplified DNA from papers inoculated with A. niger and P. rubrum and these species were found to grow less on treated Sekishu Mare and Yukyu-shi papers compared with untreated papers. Sekishu Mare papers treated with artists' acrylic paints were found to be more resistant to fungal growth than similarly treated Yukyu-shi papers. This study suggests that for the best long-term preservation outcomes for paper materials in archives, libraries, galleries, and museums, acrylic paints generally perform better in conservation terms than most plant dyes and watercolours, although most colourants displayed some bioinhibition. 相似文献

The place of the canon in institutions of higher education has been a matter for considerable debate in recent years. While there are important variations between different conservative positions in the battle over university reading requirements, many traditionalists assume that texts should be selected purely on the basis of their literary or philosophical merit, and that some people are able to objectively distinguish "Great Books" from those of lesser value. This paper concentrates on Allan Bloom's version of this thesis. Bloom suggests that "writers of quality" know other writers of quality. The author argues that Bloom's analysis is premised on a problematic theory of legitimation, a flawed conception of greatness, and a restrictive view of possibilities for reading at the university level. An alternative position - one based on the Freirean view of critical reading - is advanced. 相似文献
